Snake bite is an occupational hazard in India and important preventable cause of acute kidney injury (AKI). This study was done to estimate the magnitude of snakebite-induced AKI (SAKI)who required renal replacement therapy, prognostic predictors, and final outcome, and to measure the oxidative and carbonyl stress (CS) level in SAKI patient who underwent hemodialysis (HD). All SAKI patients dialyzed between April 2010 and July 2011 in NRS Medical College were included. Demographical, clinical, and biochemical data were analyzed, and patients are followed to discharge or death. Oxidative and CS markers (advanced oxidation protein product [AOPP], advanced glycation end product, pentosidine, dityrosine, thioberbituricacid reactive substance, and methylglyoxal [MG]) were measured in 48 SAKI patient requiring HD. About 155 SAKI patients (M: F 2.2:1 ) received HD. Of them. The age was 36.2 (range 4-74) years. The most common site of the bite was lower limb (88.7%). Oliguria and bleeding manifestation were the common presentation. Hypotension was found in 52 (33.5%) cases, cellulitis and inflammation were found in about 63%. Mean creatinine was 4.56 ± 0.24 mg/dl. About 42 (27.1%) had disseminated intravascular coagulation (DIC). 36 (78.2%) had cellulites, 24 (52.2%) had hypotension or shock at initial presentation (P < 0.05), bleeding manifestation was found in 37 (80.4%), and 22 (47.8%) had DIC (P < 0.05). Forty-six (29.7%) patient died. DIC and hypotension/shock at initial presentation came out as an independent predictor of death. Among all markers measured for oxidative and CS (n = 48) AOPP and MG came out as an independent predictor (P < 0.05) of adverse outcome. Hypotension, DIC, AOPP, and MG were a poor prognostic marker in SAKI patients requiring dialysis. [ABSTRACT FROM AUTHOR]

Spontaneous perirenal hematoma following ruptured microaneurysm is an unusual but serious complication of polyarteritis nodosa. We describe a young male who presented with spontaneous perirenal hematoma and was subsequently diagnosed to have polyarteritis nodosa. He was managed with immunosuppressive medications with no recurrence of symptoms. [ABSTRACT FROM AUTHOR]

The rare occurrence of human immunodeficiency virus (HIV) transmission through organ transplantation cannot override the huge impact that it has on the patient. We report a case of HIV transmission by renal transplantation in a 33-year-old housewife, who received a living related transplantation from her sister. Both the patient and her donor were negative by HIV antibody testing prior to transplantation, but were found to be infected in the ninth month after transplant. Further testing suggested that the donor was in the window period at the time of organ donation after having acquired the infection from her husband. [ABSTRACT FROM AUTHOR]

Glomerular diseases are an important cause of chronic renal failure in developing countries. The spectrum of diseases causing nephrotic syndrome is changing globally in the last few decades. The aim of this prospective study was to look at this spectrum at a tertiary care center in North India and to analyze the changing trends over the last five decades. Patients in the age group 18-60 years with nephrotic syndrome were consecutively included in the study. Renal biopsies were performed in all patients and were subjected to light microscopy, immunofluorescence (IF) and electron microscopy (EM). While the IF was performed in 78% of cases, EM was available in one-fourth of cases. During 2002-2007, 364 patients (60.2% males) were included in the study. The mean age was 31.5 years. Primary glomerular diseases accounted for 89% of cases while lupus nephritis was the most common secondary glomerular disease. Focal segmental glomerulosclerosis (FSGS) accounted for 30.6% of primary glomerular diseases making it the most common cause of nephrotic syndrome. It was followed by membranous glomerulonephritis (MGN) in 24.4%, mesangiocapillary glomerulonephritis in 17.9% and minimal change disease in 14.8%. In the age group >40 years, MGN was the most common lesion (32.5%) followed by FSGS (27.7%). Over the last five decades, there was a nearly five-fold increase in the incidence of FSGS, 3-fold increase in MGN and a 10-fold reduction in diffuse proliferative glomerulonephritis while there was no major change in incidence of other diseases. The biopsy diagnosis of FSGS has increased considerably in last few decades and it is now the most common cause of nephrotic syndrome in adults in North India. MGN is the most common lesion in patients over 40 years of age. [ABSTRACT FROM AUTHOR]
