Prior to the advent of combined antiretroviral therapy (cART), human immunodeficiency virus-associated nephropathy (HIVAN) was inevitably associated with rapidly progressive renal failure and dialysis dependence. HIV-1 seropositive patients often met with untimely deaths due to complications of end-stage renal disease (ESRD), opportunistic infections, or other HIV-related end-organ failure. Although the association between cART and improved outcomes in HIVAN has been recognized for over 20 years, no randomized trials have specifically examined this effect to date. In terms of reversal of dialysis-dependent renal failure after cART initiation, only a handful of case reports exist. The authors report a case of a 44-year-old Latino male requiring thrice-weekly haemodialysis in the setting of biopsy-proven HIVAN who was able to stop dialysis in 7 months after being initiated on cART.

Abstract Background Heterozygous mutations in the inverted formin 2 (INF2) gene are related to secondary focal segmental glomerulosclerosis (FSGS), a rare secondary disease associated with rapidly progressive renal failure. Case presentation We report a patient with familial autosomal INF2 mutation manifesting nephritic syndromes and elevated serum creatinine levels. Mutational analysis revealed an autosomal dominant (AD) inheritance pattern and a mutation in exon 4 (p.Arg214Cys) of INF2 as the likely cause, which has not been previously described in an Asian family. The patient progressed to end-stage renal disease (ESRD) and received hemodialysis. His mother had undergone renal transplant 3 years earlier, and his grandmother had carried the p.Arg214Cys mutation for more than 80 years without any sign of renal dysfunction. Conclusions This is the first report to identify an association between a familial autosomal dominant INF2 p.Arg214Cys mutation and rapidly progressive renal disease in an Asian family. INF2 mutation analysis should not be restricted to individuals without family history of FSGS, rather it should also be performed on individuals for whom drug-based therapies are not effective. In this case, kidney transplant is an effective alternative.

In peritoneal dialysis (PD), the peritoneum serves as a biological dialyzing membrane. The endothelium of the vast capillary network perfusing the peritoneum functions as a semipermeable membrane and allows bidirectional solute and water transfer between the intravascular space and dialysate fluid dwelling in the peritoneal cavity. PD is a renal replacement strategy for patients presenting with end-stage renal disease. It can also be offered for ultrafiltration in patients with diuretic-resistant fluid overload even in those without advanced renal failure. PD can also be used for patients with acute kidney injury, although in the developed world this occurs rarely compared to the use of extracorporeal therapies. This review contains 9 videos,  8 figures, 4 tables, and 73 references.  Keywords: peritoneal dialysis, peritoneal cavity, catheter, dialysis fluid, ultrafiltration, tunnel infection, osmotic pressure, renal failure

AbstractMicroscopic polyangiitis (MPA) is one of the main clinical presentations of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides. Although the disease is defined by clinical and pathological criteria, the anti-myeloperoxidase (MPO) specificity of ANCAs is observed in almost 80% of MPA patients. The direct pathogenic role of anti-MPO antibodies has been proven in animal models, in which the disease was transmitted by transfer of anti-MPO antibodies or anti-MPO–specific splenocytes. The most frequently affected organs in this disease are the kidneys and the lungs. Necrotizing and crescentic glomerulonephritis can be revealed by rapidly progressive renal failure, but kidney injury can be more slowly progressive and lead to end-stage renal disease without major extrarenal manifestations. The most frequent pulmonary manifestation is diffuse alveolar hemorrhage, but some patients may present with chronic interstitial fibrosis leading to respiratory failure. General signs such as fever and weight loss, muscular and articular symptoms, peripheral neuropathy, and cutaneous involvement may also reveal the disease. Although the relapse rate is quite low after induction of remission, 5-year mortality is 25%, with even higher mortality rates in older patients (> 65 years old), or those with significant kidney dysfunction. Iatrogenic causes (particularly infections) are an important cause of deaths in these vulnerable patients. Future studies are warranted to determine the optimal maintenance immunosuppressive regimen to minimize side effects of immunosuppression.

In HIV-seropositive individuals, the incidence of acute pancreatitis may achieve 40% per year, higher than the 2% found in the general population. Since 1996, when combined antiretroviral therapy, known as HAART (highly active antiretroviral therapy), was introduced, a broad spectrum of harmful factors to the pancreas, such as opportunistic infections and drugs used for chemoprophylaxis, dropped considerably. Nucleotide analogues and metabolic abnormalities, hepatic steatosis and lactic acidosis have emerged as new conditions that can affect the pancreas. To evaluate the role of antiretroviral drugs to treat HIV/AIDS in a scenario of high incidence of acute pancreatitis in this population, a systematic review was performed, including original articles, case reports and case series studies, whose targets were HIV-seropositive patients that developed acute pancreatitis after exposure to any antiretroviral drugs. This association was confirmed after exclusion of other possible etiologies and/or a recurrent episode of acute pancreatitis after re-exposure to the suspected drug. Zidovudine, efavirenz, and protease inhibitors are thought to lead to acute pancreatitis secondary to hyperlipidemia. Nucleotide reverse transcriptase inhibitors, despite being powerful inhibitors of viral replication, induce a wide spectrum of side effects, including myelotoxicity and acute pancreatitis. Didanosine, zalcitabine and stavudine have been reported as causes of acute and chronic pancreatitis. They pose a high risk with cumulative doses. Didanosine with hydroxyurea, alcohol or pentamidine are additional risk factors, leading to lethal pancreatitis, which is not a frequent event. In addition, other drugs used for prophylaxis of AIDS-related opportunistic diseases, such as sulfamethoxazole-trimethoprim and pentamidine, can produce necrotizing pancreatitis. Despite comorbidities that can lead to pancreatic involvement in the HIV/AIDS population, antiretroviral drug-induced pancreatitis should always be considered in the diagnosis of patients with abdominal pain and elevated pancreatic enzymes.

Background/Aim. The disturbances of active forms of vitamin D synthesis and disturbances in calcium and posphate metabolism develop early in chronic renal failure, when creatinine clearance is about 30 ml/min. Chronic hemodialysis and peritoneal dialysis only partially correct the biochemical environment of patients on chronic renal replacement therapy because of end-stage renal disease. These dialysis modalities can?t significantly affect the endocrine disturbances of chronic renal failure and they have minimal modulatory effect. The management of disturbed calcium (Ca) and phosphate (P) metabolism and the maintainance of Ca ? P product below 4.4 mmol/l thanks to the use of dialysate solutions with the appropriate calcium concentration and the careful dosage of phosphate binders, calcium and active vitamin D metabolits, are extremely important for the prevention of renal osteodystrophy, secondary hyperparathyroidism as well as low-bone turnover disease. The aim of the study was to analyze the plasma levels of calcium, phosphate, albumin, alkaline phosphatase and parathormon (PTH) in 58 patients who were treated with continuous ambulatory peritoneal dialysis (CAPD) from March to August 2003. The use of phosphate binders and the substitution with active vitamin D metabolits were also analyzed. Methods. We examined 58 patients, 30 males and 28 female, mean-age 52 years (range, 26-78 years), affected by end-stage renal disease of the different leading cause. The average time on peritoneal dialysis program was 20 months (2-66 months). Most of the patients were treated by CAPD, while only few of them performed automatic, cyclic or intermittent peritoneal dialysis. Most of the patients used a dialysate with 1.75 mmol/l calcium concentration. Results. The study showed that our patients on chronic CAPD program during several months had normal calcemia, phosphatemia and the level of alkaline phosphatase, and that they had Ca ? P product in the recommended range. PTH serum level ranged from 16 to 490 pg/l in our patients. Conclusion. The study showed that a balanced diet and a correct dosage of phosphate binders, as well as a careful substitution with active vitamin D metabolits render a good control of calcium and phosphate serum balance, as well as an effective prevention of renal osteodystrophy development in the patients on chronic peritoneal dialysis treatment.

Introduction: Hemodialysis is the preferred method of treatment for Nepalese patients with End Stage Renal Disease. Despite the technological advances and better understanding of physiology associated with hemodialysis, a number of complications are known to be associated with hemodialysis. This study was undertaken to study the frequency of acute intradialytic complications in patients undergoing hemodialysis. Methods: A cross-sectional study was conducted at Nephrology unit of a tertiary care hospital from 15 June, 2007 to 15 December, 2007. A total of 28 patients were included in the study. Patients with acute renal failure and acute on chronic renal failure were excluded from the study. Results: Total sessions of hemodialysis during the period were 1455. Hypotensive episode were 66 (4.5%) and was the commonest complication and followed by hypertensive episodes were 58 (3.8%). Other problems encountered were transfusion reactions were 23 episodes (1.5%), rigors not related to transfusions were 13 episodes (0.8%), nausea/vomiting were 20 episodes (1.4%), muscle cramps were 12 episodes (0.8%), hypoglycemia were 6 episodes 5(0.4%). Conclusions: The frequency of intradialytic complications is low and many of them are not life threatening. Keywords: complications; end stage renal disease; hemodialysis; hypertension; hypotension.

Abstract Mucormycosis is a rare fungal infection often seen in immunocompromised hosts. Isolated renal mucormycosis may however present in immunocompetent children as renal failure and has a uniformly poor prognosis if not detected and treated early into the course of illness. We present a 3-year-old boy with unrelenting pyelonephritis in whom serial urine cultures done were negative. A final diagnosis of isolated renal mucormycosis was made by magnetic resonance imaging and renal biopsy.
