Abstract:
Microangiopathic disease (MAP) is characterized by intravascular hemolysis resulting in anemia with presence of schistocytes on a peripheral blood smear, and with a rise in serum lactate dehydrogenase (LDH) followed by a fall in serum haptoglobin levels and with thrombocytopenia. In virtually every case of MAP, the kidney shows some degrees of injury, ranging from the appearance of proteinuria and active urinary sediment to acute kidney injury and incremental decreases in GFR. Three primary MAP’s have now been identified, based on the underlying pathophysiology and characterized according to the expectations for renal injury and the disease-specific treatment. These syndromes include classical hemolytic-uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), and atypical hemolytic-uremic syndrome (aHUS). Classical HUS is associated with enteric infection, most commonly shiga-like toxin-producing E.coli O157:H7 (STEC-HUS), with a dominant prevalence in childhood. TTP specifically arises from decreased activity of ADAM TS13, a metallaprotease that cleaves large multimers of Von Willebrand factor (vWF) causing inactivation of vWf; the deficiency of ADAM TS13 resulting in sustained presence and activity of vWf multimers. Lastly, aHUS has been linked to uncontrolled activation of the complement system by the lack of counter-regulatory factors, chiefly, factors H, I, or B. This deficiency in regulation can result from production of anti-factor F antibodies or a host of genetic mutations that affect factors F, I, or B production of activity. In addition to these well-defined syndromes, MAP with kidney injury can occur sporadically in a wide variety of unrelated disease processes. In every instance, prompt disease-specific treatment can prevent or ameliorate severe or long-term renal damage. For classical HUS, use of antibiotics to address the infection is not indicated and may be counter-productive while plasmapheresis is not beneficial. Supportive care with dialysis when indicated is the preferred mode of care. A diagnosis or strong presumption of TTP demands initiation of plasmapheresis as soon as possible with administration of corticosteroids. Rituximab may be started as initial therapy or added for disease resistance to steroid and apharesis. Absence of evidence for classical HUS or TTP, aHUS must be considered, given the high risk for progressive kidney damage. Eculizumab, a mono-specific antibody that inhibits complement factor C5 and interferes with the terminal portion of the complement cascade is the required treatment for aHUS. The expense of this drug makes it desirable to secure the correct diagnosis of the complement-mediated basis of disease by measuring factors H, I, and B activity. In the presence of normal activity of these factors, other diseases that may give rise to sporadic MAP need to be considered. A case-based analysis will be used to outline a reasonable approach to management of MAP with renal involvement.

Keynote: Why don’t you use a very effective herbal medicine, Shao-yao-gan-cao-tang (Japanese name: Shakuyaku-kanzo-to), for muscle cramp in patients on hemodialysis?
Biography:
Fumihiko Hinoshita has completed his graduation from Tokyo Medical and Dental University in 1981 (MD) and has completed his PhD from the same university, and Post-doctoral study from Harvard Medical School. He is the Head of Department of Nephrology, National Center for Global Health and Medicine, a prestigious national medical center of Japan. He has published more than 30 papers in reputed journals and served as the Lead Guest Editor for the special issue on “Hemodialysis-Associated Problems to solve: Current and Future” of the Scientific World Journal in 2013.
Abstract:
Most of the physicians in Western countries don’t know that the current traditional herval medicines, which are often used in East Asia, are very useful and effective for specific medical problems or symptoms. One of these is Shao-yao-gan-cao-tang (Japanese name: Shakuyaku-kanzo-to), an anti-cramping medicine, which exhibits an outstanding effect against muscle cramp in the patients on hemodialysis (HD), one of the most common complications of HD. Shakuyaku-kanzo-to consists of equal amounts of paeony and licorice roots and has a prophylactic anti-cramping effect. It has frequently been used for more than 20 years in Japan since the author and a few other groups started to make use of it. In our first report (Am J Chin Med 31:445-453, 2003), Shakuyaku-kanzo-to (EK-68®, Kracie Pharma, Ltd., Tokyo, Japan) at 6 g per day was prospectively administered for 4 weeks to five patients on HD who were suffering from frequent muscle cramps. Consequently, skeletal muscle cramps completely disappeared in two of the patients after the start of oral administration of Shakuyakukanzo-to. Moreover, the frequency of cramping was significantly decreased in two of the remaining three patients after persistent administration without any serious side effects. The severity of muscle cramps was also decreased by this treatment in the responsive patients. The inhibitory effect of Shakuyaku-kanzo-to on muscle contraction was also experimentally confirmed by using phrenic nerve-diaphragm preparations from male Wistar rats. Conclusively I suggest that Shakuyaku-kanzo-to of remarkable efficacy should be used to relieve pain with muscle cramp in hemodialyzed patients as soon as possible.

Title: Hypophosphatemia in users of cannabis
Time : 11:10-11:40
Biography:
Peter Edward Cadman has received his MD from Columbia University, College of Physicians and Surgeons and completed his Internal Medicine Residency and Nephrology Fellowship at the University of California, San Diego (UCSD). As an Associate Clinical Professor of Medicine at UCSD, he holds a dual appointment with both the Division of Nephrology and Hypertension and the Division of Hospital Medicine. He works as a Staff Nephrologist and Hospitalist, acting as a Clinical Educator for Medical students, Residents and Nephrology fellows. To date, he has authored or contributed to 12 different publications.
Abstract:
Cannabis has been legalized for medical and recreational use in several states, making physicians more aware of the drug’s potential toxicities. First described in 2004, the cannabinoid hyperemesis syndrome (CHS) has been recognized as a significant cause of hospitalization among drug users. Relatively little, however, has been written about electrolyte or acid-base disturbances in CHS. Between 2011 and 2014, six men were treated for CHS at the VA Medical Center in San Diego, CA and found to have significant hypophosphatemia (range <1 to 1.3 mg/dL). The six cases will be presented and possible causes of hypophosphatemia discussed. In half of the patients, serum phosphate levels normalized spontaneously within hours, suggesting redistribution of phosphate as a potential mechanism. Hyperventilation, which can lead to phosphate redistribution was observed in two-thirds of the patients and may have contributed. Hypophosphatemia is a feature of CHS in some patients.

Title: Bariatric surgery for obese live kidney donors: An analysis of risks and benefits
Time : 11:40-12:10
Biography:
Jorge Ortiz has completed his Residency in General Surgery at North Shore University Hospital. He did his Fellowship at the University of Miami Jackson Memorial Hospital. He is currently an Associate Professor of Surgery at the University of Toledo, College of Medicine and Life Sciences. He has published dozens of papers in reputed journals.
Abstract:
Background & Aim: Obesity can be a barrier to live donor selection and there are reports of obese live kidney donors (OLKDs) undergoing bariatric surgery prior to donation. While this practice has potential promise, the risks associated with it are unclear. Thus, our aim was to evaluate the advantages and disadvantages of this practice.
Design: Risks and benefits were ascertained from the literature. Analysis of costs and benefits was performed to provide objective data for each scenario.
Results: Live kidney donation is associated with superior outcomes compared to deceased donation. However, live donors are at risk of complications that could be exacerbated by obesity. Higher donor body mass index (BMI) has been associated with inferior recipient outcomes. Bariatric surgery (BS) results in decreased mortality and can induce sustained weight loss. Our cost-benefit analysis revealed a benefit-to-cost ratio of 3.64 for BS prior to live donation by OLKDs. We found ratios of 3.19 and 0.97 for live donation with an obese donor and a deceased donor, respectively.
Conclusions: Our results suggest that BS for an OLKD has the potential to increase the number of live donors and improve outcomes. However, more data is required; thus we recommend a registry of patients who have undergone both procedures.

Her main areas of interest and experience are vascular access cannulation and care, hygiene and infection control, dialysis processes analysis, safety in dialysis. Her publications focused on peritoneal dialysis, hemodialysis safety and quality and vascular access cannulation and care.
Abstract:
Introduction & Aim: There is a close link between the availability of a well-functioning vascular access and patient survival on hemodialysis. Every effort should be made to maintain the functionality of the vascular access for long-term use. Practices of access cannulation vary from clinic to clinic, mainly for historical reasons. The aim of this study is to investigate the impact of cannulation technique on the survival of the arteriovenous fistula (AVF) and grafts (AVG).
Methods: In April 2009, a cross sectional survey was conducted in 171 dialysis units located in Europe, Middle East and Africa to collect details on vascular access cannulation practices. On the basis of this survey, a cohort of patients was selected for follow-up, inclusion being dependent on the availability of corresponding access survival/intervention data in the clinical database. Access survival was analyzed using the Cox regression model (adjusted for within country effects) defining as events the need for first surgical access survival intervention. Patients were censored for transplantation, death, loss of follow-up or end of the study period (March 31, 2012). Results were adjusted for age, gender and diabetes mellitus.
Results: Out of the 10,807 patients enrolled for the original survey, access survival data was available for 7,058 (65%) of patients, these residing in Portugal, UK, Italy, Turkey, Romania, Slovenia, Poland and Spain. Mean age was 63.5±15.0 years; 38.5% were female; 27.1% were diabetics; 90.6% had a native fistula and 9.4% had a graft. Access location was distal for 51.2% of patients. During the follow-up, 51.1% were treated with antiaggregants and 2.8% with anti-coagulants. Prevalent needle sizes were 15 G and 16 G for 63.7% and 32.2% of the patients, respectively (14 G: 2.7%, 17 G: 1.4%). Cannulation technique was area for 65.8% and rope-ladder for 28.2% and the direction of puncture was antegrade for 57.3%. Median blood flow was 350-400 mL/min.
Conclusions: The study revealed that area cannulation technique, despite being the most commonly used was inferior to both rope-ladder and buttonhole for the maintenance of vascular access functionality. With regard to the effect of needle and bevel direction, the combination of antegrade position of arterial needle with bevel up or down was significantly associated with better access survival than retrograde positioning with bevel down. There was an increased risk of access failure for graft versus fistula, proximal vs. distal location, right arm vs. left arm and the presence of a venous pressure greater than 150 mmHg. The higher HR associated with a venous pressure greater than 150 mmHg should open a discussion on currently accepted limits.

Abstract:
Introduction: Studies show conflicting results regarding the long-term impact of induction therapies on kidney graft survival. The srtr database was analyzed for patients transplanted 01/2000–12/2009 who met the inclusion criteria of a prior multicenter study (risk of delayed graft function and/or acute rejection; NEJM 2006; 355: 1967) and received rATG (thymoglobulin®) or BAS induction therapy.
Methods: Registry analysis identified 90,851 deceased donor kidney graft recipients; 51,561 had risk factor status entries and met the increased risk inclusion criteria used in the prior study (NEJM 2006; cold ischemia time [cit] > 24 h, additional risk factors if cit < 24 h). Graft survival was compared for patients with and without each risk factor; Patients with functioning grafts lost to follow-up were excluded. Adjusted Kaplan-Meier survival curves were generated for each risk factor, with other covariates fixed at population means. Hazard models included rATG vs BAS induction.
Results: Of 51,561 patients receiving induction therapy, 35.7% received rATG and 17.4% received BAS. The proportion of patients receiving rATG increased from 14.2% (2000) to 53.3% (2009) ; The proportion receiving BAS declined from 30.2% (2000) to 14.5% (2009). One-year graft survival was 90.7% vs 89.9% for rATG vs BAS, respectively (p=0.02); 5-year graft survival was 69.3% vs 66.7% for rATG vs BAS, respectively (p<0.001). Improved survival for rATG vs BAS was maintained at longer follow-up.
Conclusion: Analyses suggest improved graft survival for rATG vs BAS induction therapy in transplant patients at risk of delayed graft function/rejection.

Abstract:
Objective Retrograde intra-renal surgery (RIRS) is considered as a minimally invasive procedure for management of renal stones with minimal morbidity. Our objective is to demonstrate its effectiveness in management of large, multiple and staghorn stones in our institution.
Methods A prospective study was done of 274 patients who presented to us with renal and upper ureteric stones and were managed with RIRS. Pre-operatively, stone size and laterality were assessed on NCCT KUB and X-ray KUB. Intra-operative parameters were assessed such as; operative time, need for ureteric dilatation and intra-operative complications. Post operatively, X-ray KUB/USG KUB was done before stent removal.
Results: Out of 274 patients, 185 patients were male and 89 were female. 83 patients had single stone and 191 patients had multiple stones. 25 patients were pre stented in view of septicemia or renal impairment. 47 patients had renal impairment at the time of presentation, which improved in all patients and returned to normal value in 36 patients. 85 patients underwent bilateral RIRS and 189 underwent unilateral RIRS. 175 patients had more than 2 cm sized stones. Six patients had residual stones out of which, three patients underwent URS, two patients underwent RIRS and one patient underwent ESWL.
Conclusion RIRS is feasible in case of large stone burden, like partial and complete staghorn stones along with multiple stones. Our study demonstrates its effectiveness in large stone burden with additional procedure required in < 3% patients.

Abstract:
Coxiella burnetii (C. burnetii) causes a zoonotic disease – Q fever. This bacterium is highly resistant to harsh environmental conditions and causes an uncharacteristic clinical syndrome. Q fever may be acute or chronic and renal manifestations of the disease are more common in the chronic forms. There is a few reports of acute kidney injury due to C. Burnetti and most of them were reported in chronic forms of the disease. We are going through renal manifestations of the disease and we are going to review a case of acute Q fever manifested by recurrent fever and acute kidney injury with nephrotic syndrome.

Abstract:
Percutaneous Nephrolithotomy (PCNL) is the first-line treatment modality for the management of kidney stones larger than 2 cm in diameter. The creation of a percutaneous renal access is the most important step in PCNL and the adequacy of the access directly influences the success and complication rates of this procedure. Several techniques have been used for guidance for entrance to the collecting system, including fluoroscopy, computed tomography (CT) and ultrasonography (US), however access under fluoroscopy is the most commonly used. The aim of this presentation is to emphasize the importance of the renal access, mainly the monoplanar technique, during PCNL. The access under fluoroscopy control can be performed either under biplanar or monoplanar guidance. Biplanar access is based on the cephalad-caudad and mediolateral movements of the needle; the depth of the needle is adjusted with using fluoroscopic imaging in 30 degree and vertical positions. Monoplanar access is based on the intensive movement of the kidney and the retraction of the targeted calyx under fluoroscopy on a vertical plane only. The monoplanar access technique is a safe method, it decreases puncture and radiation time, it minimizes the patient's, the surgeon's and stuff's direct exposure time to radiation and it has similar success rates as the biplanar access technique.

He is Head of Nephrology Department at Enrique Garcés Hospital, Medical Director of Dialnef Critical Care Nephrology and Medicine Professor at Universidad Central del Ecuador.
Abstract:
Introduction: Acute intoxication is an important cause of admission to intensive care unit in Ecuador; 8% of patients who needed renal replacement therapy developed by DIALNEF group since 2014 were by acute poisoning. The haemoperfusion with macro adsorbent resin offers advantages to clear toxins with medium molecular weight, high bound proteins and lipophilic characteristics.
Objective: To evaluate the role of early haemoperfusion as a therapy in severe acute intoxication. Mortality was primary outcome.
Methodology: A case and controls study was delivery in poisoning patients with neurologic deterioration by drugs with high bound proteins. Group 1 (n: 25 patients) were in haemoperfusion by 3 hours with MG-150- 250 macro adsorbent resin cartridge after general treatment for detoxifications versus group 2 (n: 25 patients) patients without access to haemoperfusion treatment. APACHE and SOFA scores were used to severity evaluation.
Results: Severity score APACHE II was G1:19 and G2: 15 (p:0.03) and SOFA G1:8.9 and G2:6 (p:0.02). UCI stay was G1:3.5 and G2: 5.4 days (p:0.11). Mortality in G1: 0 and G2: 5 (p=0,018).
Conclusions: The present study shows benefits of haemoperfusion in patients with severe acute intoxications. In addition, it shows how dramatically decreases the mortality in patients with high APACHE 2 score. Also, it was effective because decrease the permanence either in intensive care unit and hospitalization, therefore the cost is reduced. Haemoperfusion is a suitable technic for effective treatment in poisoning patients and clearance of high bound protein drugs.

Abstract:
High Blood Pressure (HBP) is a common finding in patients with chronic kidney disease on dialyses. This research analyzed the relation between blood pressure (BP) and hydration status (HS) in chronic kidney patients under hemodialysis (HD) and peritoneal dialysis (PD) in a Brazilian Dialysis Center. Demographic data, BP, number of antihypertensive drugs (NAD) and HS by bioimpendance exam were collected from 89 patients (69 in HD; 20 in PD). There were findings of 55.1% of men, age between 57.6±16.4 years old, Caucasian ethnicity (80.9%), usage of 2.4±1.2 hypotension drugs in HD, 1.7±1.4 in PD. Systolic Blood Pressure (SBP)<140 mmHg in 27.5% patients before HD, in 40.6% after HD and in 55% under PD. Diastolic Blood Pressure <90 mmHg in 81.2%, 79.7% and 85% respectively. 43.8% with mean blood pressure (MBP)>100 mmHg (86.9±9.9 mmHg) and OH 0.5±2.5 liters. 56.2% with MBP>100 mmHg (114.7±11.9 mmHg; p=0.0001) and OH of 1.5±2.7 liters (p=0.06 between the groups). When pre-dialysis SBP and HS were combined, the patients were stratified in 4 groups: Group-1; 40.4% HBP can relate to hyperhydration; Group-2; 24.71%, HBP is independent of hyperhydration; Group-3; 19.1%, in which 9% are hypohydrated and low blood pressure; Group-4; 15.7%, in which 12.3% are normohydrated and normotensive and 3.4% are hyperhydrated, though normotensive or arterial hypotension. HS was normal in 22.5%. In this research, there was noted the difficulty of controlling BP in these patients despite the use of expressive NAD and no relation between HS and MBP.

Daniel Santos Rocha Sobral Filho is a Medical Student at Federal University of Piauí, Teresina - Piauí – Brazil and has Scholarship of the Program of Scientific Initiation of the Federal University of Piauí. He participates in researches in nephrology, focusing on genetic nephropathies.
Abstract:
Fabry disease (FD) is a rare X-linked disorder resulting from the deficiency of alpha-galactosidaseA enzyme. Microalbuminuria is the initial manifestation of renal involvement, progressing to end-stage renal disease. From one case, we followed the patient's response to enzyme replacement therapy (ERT) and the evolution of its manifestations. A 61 years old male was referred to nephrologist to investigate generalized edema and massive proteinuria. He referred a previous diagnosis of cardiomyopathy and heart failure treatment. Physical examination revealed widespread edema. Complementary tests showed nephrotic proteinuria, hypoalbuminemia and dyslipidemia. Renal biopsy revealed membranous glomerulonephritis (MN) and FD association. Anti-phospholipase-A2-Receptor autoantibodies were positive, revealing the unprecedented association between idiopathic MN and Fabry nephropathy, reinforces the hypothesis that Fabry's nephropathy may modify podocyte antigens, leading to idiopathic MN. Others FD manifestations were found: cornea verticillata, hypertrophic cardiomyopathy and supratentorial microangiopathy. The α-Gal activity was reduced, associated with lyso-Gb3 accumulation. Genetic analysis identified an unreported hemizygous mutation in exon 7 of the GLA gene. The patient experienced decreased edema and clinical stabilization with the institution of fortnightly ERT with agalsidase alfa, with complementary exams showing preservation of renal function with reduction in proteinuria and increased serum albumin. Family screening identified six close relatives with FD on oligosymptomatic stage. This study recognized an unknown association between MN and FD and an unreported genetic mutation. It’s also serving as the basis for the development of a database that aims to allow the follow-up of these patients, making possible the analysis of clinical data and of its evolution.

Time : 17:30-18:00
Biography:
David H King is currently a Consultant Nephrologist at the Department of Nephrology, Division of Medicine, Broomfield Hospital, UK.
Abstract:
We have re-visited the use of Static Pressure Ratio developed by Anatole Besarab et al. Arterial needle pressure is monitored with dialysis pump switched off. Pressure will rise to abnormal levels in the presence of a blood flow limiting venous stenosis. The method is not widely used, possibly due to difficulties in compensating for hydrostatic height difference and the need to interrupt the dialysis routine. The Bluedop™ device is intended to measure mean blood pressure non-invasively, without the use of needles, is unaffected by pump speed and can be applied at any suitable part of the AVF without any requirement for hydrostatic height correction. We have named our new parameter Non Invasive Static Pressure Ratio SPRn and have studied its role in early detection of failing AVF. A Doppler Ultrasound probe is used to sample blood flow waveforms from the distal brachial artery. The same protocol is used for radio-cephalic and brachio-cephalic AVF. The range of SPRn values±2SD in normally functioning AVF was established in 479 dialysis patients. Following this 340 prospective measurements were made on 73 patients over a 10 week period. SPRn in 27 AVF rose above the +2SD normal limit. Of these, 23 had 60% or greater focal stenosis shown on duplex scanning, 2 were maturing AVF and 2 had no significant stenosis. An earlier retrospective review of clinically identified failing AVF in the same unit showed that nearly half were found to be normal in duplex studies. This new Bluedop™ test has the potential to improve the care pathway for renal dialysis patients.

Her clinical research interests include glomerulopathies, childhood hypertension and BK virus infection. As a Junior Faculty, she started the Pediatric Hypertension Clinic at University of Florida in 2015. She has given a CME talk on Pediatric Hypertension to community pediatricians and has lectured to medical students and residents on various nephrology topics.
Abstract:
Background: Membranoproliferative glomerulonephritis (MPGN type I, II, III) was reclassified in 2013 as MPGN and C3 glomerulopathy (C3G) based on classical or alternative pathway complement activation.
Objectives: To evaluate whether C4d, a component of the classical pathway could be a diagnostic tool in differentiating between MPGN and C3G.
Methods: We conducted a retrospective study of 15 MPGN type I, II, III and 13 minimal change disease (MCD) patients from 2000 to 2012. Formalin-fixed paraffin-embedded kidney tissues were stained for C4d using an immunoperoxidase method.
Results: Using the 2013 C3G consensus classification, the 15 MPGN types I, II, III biopsies were re-classified as MPGN (8) and C3G (7). Based on C4d immunohistochemical staining, of the 8 biopsies diagnosed as MPGN, 4 had classical pathway involvement [C1q (+), C3 (+), C4d (+)]; two had lectin pathway involvement [C1q (-), C3 (+), C4d (+)]; and, two were reclassified as C3G because the absence of C4d and C1q suggested the presence of the alternative pathway [C1q (-), C3 (+), C4d (-)]. Three of seven C3G biopsies presented classical pathway and were reclassified as MPGN. The alternative pathway was present in one of the other 4 considered to be C3G; the other two C3G biopsies likely involved the lectin pathway. The one case of dense deposit disease had lectin pathway involvement.
Conclusions: This study reports that C4d staining may help to differentiate between MPGN and C3G. In addition, the lectin pathway seems to play a role in the pathogenesis of these glomerulopathies.

Objective: Prevention of exit site infection (ESI) is of paramount importance to peritoneal dialysis (PD) patients. The aim of this study was to evaluate the effectiveness of chlorhexidine in the prevention of ESI in incident PD patients compared with mupirocin.
Methods: This retrospective, pre-test/post-test observational study included all incident PD patients at Singapore General Hospital from 2012 to 2015. Patients received daily topical exit-site application of either mupirocin (2012-2013) or chlorhexidine (2014-2015) in addition to routine exit-site cleaning with 10% povidone-iodine. The primary outcome was ESI rate during the 2 time periods. Secondary outcomes were peritonitis rate, times to first ESI and peritonitis, hospitalization rate and infection-related catheter removal. Event rates were analyzed using Poisson regression and infection-free survival was estimated using Kaplan-Meier and Cox regression survival analyses.
Results: The study included 162 patients in the mupirocin period (follow-up 141.5 patient-years) and 175 patients in the chlorhexidine period (follow-up 136.9 patient-years). Compared with mupirocin-treated patients, chlorhexidine-treated patients experienced more frequent ESIs (0.22 vs 0.12 episodes/patient-year, p=0.048), although this was no longer statistically significant following multivariable analysis (incidence rate ratio [IRR] 1.78, 95% confidence interval [CI] 0.98-3.26, p=0.06). No significant differences were observed between the 2 groups with respect to time to first ESI (p=0.10), peritonitis rate (p=0.95), time to first peritonitis (p=0.60), hospitalization rate (p=0.21) or catheter removal rate (0.03 vs. 0.04/patient-year, p=0.56).
Conclusions: Topical exit-site application of chlorhexidine cream was associated with a borderline significant, higher rate of ESI in incident PD patients compared with mupirocin cream.

Abstract:
Nutritional status assesment in dialysis patients is very important since malnutrtion in dialysis is common and increases morbidity and mortality.The commonly used mehtods such as; BMI, anthropometry are not accurate for assessing the nutritional status in dialysis patients because of their altered fluid status. However, adding subjective global assessment (SGA) or malnutrition inflammatory score (MIS) to anthropmetry may provide better information. The fat mass, fat free mass (lean body mass) are the two most important parameters of nutrition and can be abnormal even with normal body weight in dialysis patients. DEXA scan, CT, MRI which are relatively simple methods to perform but involve expertise to analyze the data are a bit more expensive and expose patients to ionizing radiation. More accurate methods such as dueterium oxide and total body potassium estimation are complex, and used as advanced tools. Bioimpedance analysis (BIA), a relatively simpler, cheaper, bedside and user freindly tool has become more popular in the recent past in assesing the nutritional status in dialysis patients. In our expereince, bioimpedance analysis yielded body composition parameters which correlated well with BMI and anthropometric parameters in a subset of our dialysis patients. In addition, we found that subjective global assesment is also a less expensive method and provided nutritional as well as functional status in our dialysis patients. We conclude that, in our experience, bioimpedance analysis and subjective global assessment are simple tools and are complimenary to anthropometry for nutritional assesment in dialysis patients.

Abstract:
The management of the pain therapy (ischemic pain, neoplastic pain) in hemodialysis patients has become a frequent challenge in the last years. These patients often require the prescription of major analgesic drugs such as opioids like Fentanyl, in order to control the pain. It is necessary to pay attention to the correct dosage and to the half-life of these drugs that results prolonged in the chronic renal insufficiency. The main side effect of opioids is respiratory depression and is well known, but to date in the literature reports about other less frequent side effects, like epilepsy or status epilepticus are lacking. We report two cases of chronic hemodialysed patients who developed a generalized non-convulsive status epilepticus secondary to fentanyl intoxication administered for the pain therapy. These cases required a synergic team management implicating the nephrologists, the neurologist and the intensivist. The generalized non-convulsive status epilepticus could be an important and serious side effect of fentanyl in hemodialysis patients and it is therefore necessary a sharp monitoring of the pain therapy in these subjects.

Abstract:
Wilms’ tumor suppressor gene 1 (WT1) mutations are found in Denys-Drash syndrome, Frasier syndrome and isolated diffuse mesangial sclerosis; these mutations lead to the occurrence of diffuse mesangial sclerosis (DMS) and focal segmental glomerulosclerosis. Nephrotic syndrome (NS) caused due to DMS is unresponsive to drug therapy and is characterized by rapid progression to end-stage renal disease. Here, we report a case of a 3 years and 5 months old girl with NS caused due to DMS who responded favorably to cyclosporin A (CsA) and angiotensin-I converting enzyme inhibitor (ACE-I). The light microscopic findings of the renal biopsy before CsA therapy revealed the early stage of DMS, which showed small glomerulus with diffuse mesangial matrix increase and mesangial hypercellularity and hyperplastic podocytes. However, prominent epithelial proliferation was not found in the specimen. CsA therapy induced a dose-dependent decrease in her urinary protein/creatinine ratio and resulted in partial remission of NS and maintenance of normal renal function for over 3 years. The second biopsy at 3 years old revealed the improvement on the light microscopic findings. CsA may be effective for DMS with WT1 mutations, if therapy is started before creatinine levels increase and in the early stage of DMS. In children with WT1 mutation, CsA therapy may prevent prompt progression to end-stage renal disease.

Title: Ulinastatin: Is it a new therapeutic option for AKI?
Biography:
Sonia Gupta has completed her medical education along with the specialization in Nephrology from Institute of Kidney Diseases in Ahmedabad, India. At present, she runs her own kidney hospital Kidney Care Hospital & Research Center Udaipur. She has more than 15 publications to her credit and tries to focus on delivering affordable quality nephrology care to her patients.
Abstract:
Background: In critically ill patients with AKI, unacceptably high mortality rates reaching up to 50-80% in all dialyzed ICU patients are seen despite the availability of intensive renal support. At present there is no specific or targeted therapy for AKI. The exact molecular pathophysiology of AKI is complex and also multifactorial. Ulinastatin is a multifunctional Kunitz type serine protease inhibitor; it has been shown to exhibit significant renoprotective effects in various models of mechanical and chemical injury.Our premise regarding the use of molecule in AKI was based on the fact that this molecule acts at multiple levels in the sepsis conundrum and can act to stop the cascade and thereby halt the “storm”.
Aim: The aim of our study, done in a semi urban nephrology set up, was to find out if using ulinastatin in patients with AKI has any beneficial result on the outcomes in patients with AKI. Ours is a retrospective comparative study done in patients with AKI who were critically ill.
Method: We studied a total of 280 patients with AKI who needed ICU care in our hospital in the period between May 2012- Dec 2015. Out of these, 140 patients received Injection ulinastatin 3 doses a day for 5 days, against a similar number of control patients. We included those patients with AKI who had SOFA scores more than 8. We recorded the age and the etiologies of the patients. We recorded the length of stay, need and duration of renal replacement therapy, time to stoppage of renal replacement therapy, need for mechanical ventilation, mortality and post AKI recovery and progression to CKD.
Results: The patients who received ulinastatin had a shorter stay in the ICU (p <0.01 vs control group); also the time to stoppage of renal replacement therapy was shorter (p < 0.05). The recovery to renal function was seen in 84% (n=118). The progression to CKD was seen in 11% (n=10; 20 in control group), of patients .The average number of sittings of dialysis needed were 11 (range3-20), less number of dialysis were needed in the ulinastatin group .The overall mortality was 26 %( n=72, 39 in the control group).

Biography:
Shinnosuke Kuroda has completed his graduation from Yokohama City University School of Medicine. He has worked at Ohguchi Higashi General Hospital in Japan from 2014 to 2015. He has published more than 10 papers about male infertility and urolithiasis.
Abstract:
Objectives: To compare outcomes of retrograde intrarenal surgery for urolithiasis between patients with solitary kidneys and patients who have single-side urolithiasis with bilateral kidneys.
Methods: We retrospectively analyzed outcomes of retrograde intrarenal surgery in solitary kidney patients (group A) carried out during 2007-2014 and in patients with bilateral kidneys with comparable stone burdens (group B). Stone-free status was defined as no residual fragment on computed tomography 1 month later.
Results: There were 19 patients in group A (mean age 62.5±18.4 years, range 14-76 years). The mean stone diameter and burden were 6.0 mm (range 3-24 mm) and 10.42±6.92 mm, respectively. The stone-free rate was 94.7% and no repeat procedure was required. The glomerular filtration rate tended to rise post-surgery (postoperative day-1: 48.67±15.92 mL/min, 100.2%, P=0.940; postoperative month-1: 51.32±16.90 mL/min, 105.7%, P=0.101) compared with preoperative rates. The stone-free rate and surgery time were not significantly different between the two groups, although post-surgical hospitalization time was longer for group A (4.05 vs. 3.08 days, P=0.037). The change in glomerular filtration rate was not significantly different between groups A and B (postoperative day-1: +0.101 vs. +0.547 mL/min, respectively, P=0.857; postoperative month-1: +2.749 vs. 3.161 mL/min, respectively, P=0.882). No significant difference was found in terms of complication rate.
Conclusions: Retrograde intrarenal surgery in solitary kidney patients is as safe and effective as in bilateral kidney patients.

Abstract:
Diabetic Kidney Disease (DKD) is a global health concern that is associated with high morbidity and mortality. Patients with DKD are expected to manage their daily self-care activities. Patients’ non-adherence to treatment regimen is thought to be the major cause for the poor control and the occurrence of complications. Previous research has shown that multidisciplinary management of DKD can improve patient outcomes. The effect of nurse-led multidisciplinary self-care management on Quality of Life (QoL), self-care, adherence to antihypertensive therapy, glycemic control and renal function of patients with DKD is not yet well established. The aim of this study was to investigate the effect of a nurse-led Multidisciplinary Self-care Management Program (MSMP) on QoL, self-care behavior, adherence to anti-hypertensive therapy, glycemic control and renal function of adults with DKD. A uniform balanced cross-over design was used with 32 participants randomized into four study arms. Cross-over designs allow efficient comparison of treatments when recruiting fewer participants and attaining the same level of statistical power as randomized controlled trials. It is for use more importantly in chronic diseases for comparison of participants’ responses to different treatments. Each participant receives treatment and serve of own control thus, overcoming the mixed effects related to heterogeneity of co-morbidities when comparing two different groups. The uniform strongly balanced design represents the ideal cross-over because it overcomes the statistical bias of carry-over effect. Each participant received twice, at different time intervals and over 12 months, three months of Usual Care (UC) alternating with three months of MSMP. QoL was evaluated using the Audit of Diabetes-Dependent QoL scale, patient self-care behavior was measured using the Revised Summary of Diabetes Self-Care Activities and adherence to anti-hypertensive therapy was assessed using the Medication Events Monitoring System (MEMS). Blood glucose control was measured by glycated hemoglobin (HbA1c) levels and renal function by serum creatinine, estimated glomerular filtration rate and urinary albumin/creatinine ratio. The present QoL was improved by MSMP with a higher mean rank (55.95) as compared to UC (42.19) (p<0.05, Confidence Interval (CI) of 95%). MSMP also improved the general diet habits, diabetes specific diet habits and blood sugar testing frequency demonstrating overall higher mean ranks as compared to UC (p<0.01, 95% CI, respectively 59.56 vs. 39.44, 59.98 vs. 37.02 and 57.75 vs. 40.43). Results of glycemic control and renal function did not show a significant difference between MSMP and UC. MEMS adherence overall percentage mean (n=21) over the 12 months, for UC and MSMP confounded was high (95.38%, Minimum=69%, Maximum=100%). The implementation of a nurse-led multidisciplinary self-care management program with a theory-based nursing practice improved general QoL and self-care activities of DKD patients.

Abstract:
Introduction: Estimating glomerular filtration rate (GFR) in obese subjects is a challenge. An analysis is made from the performance of equations to estimate GFR in this population.
Materials & Method: This cross-sectional study included 100 obese subjects evaluated between 2008 and 2015. The GFR was measured with urinary iothalamate clearence (reference standard) and estimated using creatinine-based formulas: Cockroft Gault, MDRD, CKD-EPI, MCQ and CKD-MCQ (mean of these). A global performance score (G-P-Score) was created to unify all the analysis criteria.
Results: CKD-MCQ equation had the best performance in obesity grade I (n=53) [bias=1.6 +/- 17.4 ml/min × 1.73 m2; correlation (r)=0.87; area under the curve (AUC)=0.978; sensitivity (S) =100%; specificity (E)=87.8%]. MCQ and CKD-MCQ had the lowest bias in obesity grade II (n=25) (bias=1.8 +/- 22.3 and -4.4 +/- 21.9 ml/min × 1.73m2) and CKD-MCQ the highest r (r=0.89), with the same AUC, S, and E (AUC=0.976, S=85.7%, E=100%). MDRD equation had the lowest bias in obesity grade III (n=22) (bias=-0.2 +/- 31.1 ml/min × 1.73 m2), and CKD-MCQ had the highest r and AUC (r=0.66, AUC=0.929), with the same S and E (S=80%, E=94.1%) than MDRD. CKD-MCQ was the only equation without significant differences compared to the reference standard in any of the obesity levels. The highest score was obtained in the G-P-score (39/48).
Conclusion: CKD-MCQ had the better overall performance for estimating GFR in subjects with different degrees of obesity.

Abstract:
Hypertension is one of the most common causes of cardiovascular morbidity and mortality worldwide. Several factors contribute to the development of hypertension. Similar to non-transplant population, hypertension remains high prevalence in kidney transplant recipients. Among kidney transplant recipients with pre-transplant hypertesion, the majority of them still continue to be hypertensive after successful kidney transplantation; however, some kidney transplant recipients become normotensive. Etiology of hypertension is difficulty to determined and it is likely multifactorial including genetic and acquired conditions. Kidney is thought to be one contributing factor of hypertension and this may represent in the form of genetic kidney disease. Native nephrectomy in non-transplant patient is one possible way to manage uncontrolled hypertension. Our previous data demonstrated that kidney transplant recipients who received living-unrelated renal transplantation appeared to have lower prevalence of post-transplant hypertension compared to the recipients receiving living-related renal transplantation. For deceased donor renal transplantation, hypertensive patients receiving kidney transplantation from the same donor (mated kidney transplantation) seemed to convert to normotensive or remain hypertensive at the same direction. This may implies a potential role of genetic kidney diseases. In addition to potential genetic causes of post-transplantation hypertension, other treditional non-genetic risk factors of post-transplant hypertension are still important since these may be reversible or preventable conditions. These common conditions or diseases include obesity. Since post-transplant hypertension is high prevalent and crucial for kidney transplant outcomes both renal allograft and patient survivals, identifing the causes of post-transplant hypertension should lead to strategies for preventing post-transplant hypertension and mitigate poor kidney transplant outcomes.

Abstract:
Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common hereditary kidney diseases that develop end-stage kidney disease. Usage of renin-angiotensin-aldosterone system inhibitors and educational campaign such as salt restriction and metabolic syndrome have successfully delayed initiation of dialysis in the other kidney diseases. However, ADPKD patients have obtained littele benefit from these appearance of medicine or activities. As a result, ADPKD now requires dialysis at a younger age than the other kidney diseases. Tolvaptan is the first drug that directly inhibits growth of kidney cysts. TEMPO 3:4 study clinically showed efficacy and safety of tolvaptan treatment among ADPKD patients with creatinine clearance more than 60 mL/min. This medicine improved decline of kidney function as well as enlargement of total kidney volume. Polyuria is frequently present, and tolvaptan requires sufficient fluid intake. According to TEMPO 3:4 study, tolvaptan can be administered to ADPKD patients with chronic kidney disease (CKD) G1-G4 since 2014 in Japan. Tolvaptan has been administered to ore than 1,000 ADPKD patients. Approval of indication including CKD G3 and G4 resulted in the current situation that CKD G3 and G4 is dominant in tolvaptan-treated patients. I will introduce therapeutic effect and amount of fluid intake and urine volume in tolvaptan treatment.

Title: Vitamin D repletion after kidney transplantation
Biography:
Kyra Borchhardt has completed her studies at Medical University of Vienna and Post-doctoral studies from Stanford University School of Medicine. She is the Medical Director of the Dialysis Institut of Klagenfurt, Austria.
Abstract:
Objectives: Vitamin D deficiency has been associated with detrimental renal allograft outcome, yet interventional studies on vitamin d supplementation after kidney transplantation are not available. We aimed to test whether treatment of vitamin d deficiency improves renal allograft function by preventing infections and acute rejections, and improves bone mineral density one year after kidney transplantation.
Design: The study is a single-center randomized double-blind placebo-controlled clinical trial with one-year follow-up.
Setting: The study was conducted at the Medical University of Vienna, austria between may 2009 and august 2014. Participants: we studied 203 deceased-donor kidney-only transplant recipients with vitamin D deficiency (25-hydroxyvitamin D levels <20 ng/ml) at the time of transplantation. Patients who underwent re-transplantation more than twice, as well as immunologically high-risk patients were excluded.
Interventions: Participants were randomly assigned to receive daily treatment with oral vitamin D3 (6800 international units) or placebo for one year. Main outcome measures: primary outcome was renal allograft function at one year post-transplant (estimated by serum creatinine) with the combined event rate of acute rejections and infections as a co-primary endpoint. Secondary outcomes included time course analyses of serum creatinine and c-reactive protein levels, bone mineral density, serum levels of parathyroid hormone, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, and cathelicidine. Besides intention-to-treat analyses, per-protocol analyses were performed at twelve (n=63 in the vitamin D3 and n=60 in the placebo group) and six months (n=70 in the vitamin D3 and n=65 in the placebo group), including patients who completed the follow-up.
Results: Out of 610 consecutively screened kidney transplant candidates, 203 were included and randomly assigned to vitamin D3 (N=103 with mean 25-hydroxyvitamin D levels of 11.6±4.9 ng/ml at baseline) or placebo (N=100 with mean 25-hydroxyvitamin D levels of 11.1±4.8 ng/ml at baseline). The novel supplementation regimen led to a fast and persistent increase in 25-hydroxyvitamin D levels (+22.6 (quartiles 7.5-36.9) ng/ml in the vitamin D3 group vs. -0.3 (-4.6-3.9) ng/ml in the placebo group at one year post-transplant, p<0.001). One-year serum creatinine levels were similar in the vitamin D3 and placebo group in the intention-to-treat analyses, but were higher in vitamin D3-treated patients in the per-protocol analyses at twelve (1.54 (1.32-2.17) mg/dl vs. 1.42 (1.20-1.73) mg/dl, p=0.03) and six months (1.61 (1.36-2.13) mg/dl vs. 1.43 (1.19-1.82) md/dl, p=0.01). There was no group difference in the monthly combined event rate of acute rejections and infections (0.25 (0.09-0.44) in the vitamin D3 and 0.33 (0-0.71) in the placebo group, p=0.73) or the course of C-reactive protein levels or serum levels of cathelicidin. Changes in lumbar and femoral bone mineral density over time were similar in both groups. Vitamin D3 therapy resulted in significantly lower serum levels of parathyroid hormone (median 96 (quartiles 61-139) pg/ml vs. 128 (89-172) pg/ml, p=0.02), and significantly higher serum levels of 1,25-dihydroxyvitamin D (50 (38-75) pg/ml vs. 35 (24-49) pg/ml, p<0.001). Hypercalcemia was more common during vitamin D3 supplementation (30% vs. 17%, p=0.04).
Conclusions: Given the lack of an overall benefit of vitamin D supplementation, as well as its potential adverse effect on renal allograft function and its hypercalcemic potential, vitamin D supplementation is not justified in kidney transplant recipients.

Abstract:
Kidney is the most commonly injured genitourinary organ (65%). Kidney trauma occurs in approximately 1-5% of all trauma cases. The present study was performed to describe and analyze the characteristics of hospitalized patients in Saiful Anwar Hospital (SAH). During January 2005 to December 2016, 63 of kidney trauma patients in SAH were retrospectively studied. The data were analyzed based on demographic characteristic, chief complaint, mechanism of injury, hemodynamic stability state, grading and location of trauma and management. The association of hemodynamic state, type of management, anemic condition, grade of kidney trauma to patient’s outcome was analyzed using SPSS. It occurred mostly in male patients (47/74.6%), pediatric involve (22/34.9%) of total patients. Motor vehicle injury was the most common mechanism of injury (50/79.4%). Most of the patients came with flank pain as a chief complain (42/66.7%). Trauma were occurred mostly due to blunt trauma (61/96.8%), more frequent cases involved right kidney (33/52.4%). Grade I kidney trauma is the most frequent occurred (40/63.5%) and stable hemodynamic state (52/82.5%). Mostly patients treated with non-operative management (60/95.2%) and no significant difference of length of hospitalization was noted between conservative and operative treatment (p=0.625). There were significant association between hemodynamic state and treatment options (p=0.047). However no association was noted between type of management and patients’ outcome (p=0.436). Severe grade of trauma revealed increasing nephrectomy rate (OR: 174, 95% CI: 8.62-315.174 p<0.01). Most of its patients in SAH were uneventfully treated by conservative treatment. Severe grade of trauma increased risk of nephrectomy.

Abstract:
Introduction & Purpose: Staghorn and multiple renal stone diseases have been a challenging problem, and require multiple modalities for complete clearance. The purpose of this study is to discuss about the innovative and advanced retroperitoneoscopic surgery performed for this morbid condition.
Material & Method: Since 1992, 336 cases of urinary stones were operated by this technique out of which, 65 cases were of staghorn and multiple stone diseases. Apart from laparoscopic instruments, rigid and flexible nephroscope, dormia basket, grasping forceps and flushing cannula were used. Standard kidney position was used with 3 to 4 ports. 43 cases were male, 22 cases were female. The age of the patients ranged from 11 years to 65 years. Ureteric catheter or DJ stent was introduced before operation.
Results: All the operations were performed successfully except two conversations in initial period. Blood transfusion was given into two patients in the post-operative period (one unit in each patient). Post-operative urine leak stopped in 24 to 72 hrs. Duration of surgery ranged from two hours 45 minutes to four hours 35 minutes. Post-operative x-rays showed residual stones in kidney in three patients and in the retroperitoneum in four patients. Residual stones in kidney were treated by ESWL after six weeks. Hospital stay was 4-6 days. No postoperative urinary tract infection occurred from the surgery. Two patients had port infection. One patient had urinoma due to lockage of drain.
Conclusion: Retroperitoneoscopic surgery for staghorn and multiple stones is minimally invasive and less traumatic to kidney. It is comparable with open surgery and accepted by patients. Post-operative discomfort in more as compared By PCNL.

Abstract:
Background: Renal replacement therapy (RRT) is the treatment of choice for patients with end stage renal failure, RRT include dialysis and kidney transplantation. Most sub-Saharan African countries have not developed renal transplantation services and are relying on referring patients to overseas countries. This study was carried out to describe renal transplantation experience in Tanzania.
Methods: Forty four renal transplant recipients were recruited in this study. Standardized questionnaire and Swahili version of standard form – 36 (SF-36) were used to collect socio-demographic information, clinical data, laboratory test results and health related quality of life information.
Results: Ages of transplant recipient ranged from 21 to 66 years with mean age of 45.9 ± 10.5 years. The leading causes of end stage renal failure among participants was hypertension 58.8% (25/44) followed by glomerulonephritis 15.9% (7/44). Twenty eight (63.6%) of transplantations were paid by the government. Most of the donors (97.7%) were living out of which 26 (59.1%) were siblings and 11 (25%) were second degree relatives (cousins and nephews). Most common complication noted following transplantation was diabetes mellitus 9 (20.5%) and 3 (6.8%) had chronic rejection. Mental health was the domain with highest mean score (75.6 ± 14.3) and role physical had the least mean score (44 ± 45.6).
Conclusions: Hypertension was the leading cause of ESRF in this study. Most of the donors were siblings and the costs of transplantation were largely covered by the government. There is a need for concerted effort to establish local kidney transplantation services in Tanzania.
