Kimura&am... more Kimura's disease is a rare chronic eosinophilic inflammatory disorder of unknown etiology. Majority of cases have been reported from South East Asia, while sporadic occurrences have been reported worldwide, including the Indian subcontinent. Nephrotic syndrome may be the presenting manifestation of Kimura's disease, and a variety of renal lesions are observed histologically in such patients. We herein describe a case of steroid-responsive mesangioproliferative glomerulonephritis related to kimura's disease.

New onset diabetes mellitus after transplantation (NODAT) is a serious and common complication following solid organ transplantation. NODAT has been reported to occur in 2% to 53% of all solid organ transplants. Kidney transplant recipients who develop NODAT have variably been reported to be at increased risk of fatal and nonfatal cardiovascular events and other adverse outcomes including infection, reduced patient survival, graft rejection, and accelerated graft loss compared with those who do not develop diabetes. Identification of high-risk patients and implementation of measures to reduce the development of NODAT may improve long-term patient and graft outcome. The following article presents an overview of the literature on the current diagnostic criteria for NODAT, its incidence after solid organ transplantation, suggested risk factors and potential pathogenic mechanisms. The impact of NODAT on patient and allograft outcomes and suggested guidelines for early identification and management of NODAT will also be discussed.

Our aim is to study the clinicopathological features and outcome of CSGN. It is a retrospective observational study from a tertiary care hospital in India over 3.5 years. Biopsy-proven cases of CSGN (i.e., >50% crescents in glomeruli) were included in the study. Cases with insufficient data were excluded. There were 34 cases of CSGN, accounting for an incidence of 5.5% among kidney biopsies. The mean age was 32.2 ± 16.09 years, with male to female ratio of 12:22. Clinical presentations of CSGN include rapidly progressive glomerulonephritis in 23 (67.7%), chronic renal failure (CRF) in seven (20.5%), nephrotic syndrome in two (5.8%) and acute nephritic syndrome in two (5.8%) patients. The immunological profile of CSGN showed MPO-ANCA in nine (26.4%), PR3-ANCA in one (2.9%), both PR3 and MPO-ANCA in one (2.9%), anti-GBM antibody in five (14.7%) and lupus nephritis in six (17.6%) patients. All the three antibodies were present in one patient. The percentage of glomeruli showing crescents were 100% in nine (26.4%) and ≥80% in seven (20.5%) patients. Type of crescents seen were cellular in 11 (32.3%) and fibrocellular in 22 (64.7%) patients and fibrous in one (2.9%) patient. Interstitial fibrosis was found in seven (20.5%) patients. Dialysis dependency was seen in 11 (32.3%) patients. After 3 months of follow-up, mortality was seen in three (8.8%), remission in eight (23.5%), CRF in 15 (44.1%) and ESRD in five (14.7%) patients. CSGN carries a poor prognosis. The disorder may have an insidious onset and a slowly progressive course. ANCA, anti-GBM-antibody and anti-dsDNA can coexist in CSGN.

Sixty patients were randomized in four groups; group A1 = non-diabetic CKD given trial drug Salacia oblonga for six months, group A 2 = non-diabetic CKD intended to receive placebo, group B1 = diabetic CKD treated with Salacia oblonga for six months and group B 2 = diabetic CKD patients intended to receive placebo. Estimation of renal function tests including blood urea, serum creatinine and creatinine clearance was performed at baseline and after that at monthly intervals. Lipid profile, interleukin-6 (IL-6) and C-reactive protein (CRP) were measured at baseline and were repeated at three months and six months. After six months of treatment, Salacia oblonga could reduce the triglyceride levels by 23.66% (P = 0.008) in non-diabetic and by 17.45% (P = 0.01) in diabetic CKD patients. In comparison with placebo, both non-diabetic and diabetic CKD patients treated with Salacia oblonga showed significant reduction in CRP levels (P = 0.002 and 0.03, respectively), while significant reduction in IL-6 (P-value = 0.0003) and serum cholesterol levels (P-value = 0.0001) was seen only in diabetic CKD patients treated with Salacia oblonga. Stabilization of creatinine clearance with Salacia oblonga was observed in both non-diabetic (P = 0.05) and diabetic CKD (P = 0.04) patients in comparison with placebo. Salacia oblonga has significant beneficial effects on lipid profile and markers of inflammation and endothelial dysfunction in CKD patients. Salacia oblonga also seems to have a reno-protective effect, as reflected by stabilization of creatinine clearance at six months in this study.

This study was performed to evaluate the various intradialytic complications that occur during HD and their management. This is a retrospective study performed in patients who underwent conventional HD during the period of 1 January 2000 to 31 December 2011 at our center. Clinical details, various complications faced and their management were retrieved from dialysis case sheets. A total of 2325 patients of renal failure (790 ARF and 1535 CRF patients) were assessed for the intradialytic complications of HD. During the study period, there were 12,785 bicarbonate dialyses performed on these patients. In the ARF patients, the common intradialytic complications were: Hypotension, seen in 1296 sessions (30.4%), nausea and vomiting seen in 1125 sessions (26.4%), fever and chills seen in 818 sessions (19.2%), headache seen in 665 sessions (15.6%), cramps seen in 85 sessions (2.0%), chest pain and back pain seen in 82 sessions (1.92%), hypoglycemia seen in 77 sessions (1.8%), first-use syndrome seen in 72 sessions (1.7%) and femoral hematoma seen in 31 sessions (0.73%). In the CRF group, common complications were hypotension in 2230 sessions (26.1%), nausea and vomiting in 1211 sessions (14.2%), fever and chills in 1228 sessions (14.4%), chest pain and back pain in 1108 cases (13.0%), hypertension in 886 sessions (10.4%), headache in 886 sessions (10.4%), cramps in 256 sessions (3.0%), hematoma in 55 sessions (0.64%), intracerebral hemorrhage in three sessions (0.03%) and catheter tip migration in three sessions (0.03%). There is a need for special attention for the diagnosis and management of intradialytic complications of HD because such complications could be managed successfully without the need for termination of the dialysis procedure.

The causes of amyloidosis vary from country to country and from time to time at individual center. This study investigates the changes in epidemiological and clinical profile of renal amyloidosis in recent years. Cases of biopsy-proven renal amyloidosis from January 1992 to December 2010 were studied retrospectively. They were divided into two groups: 1990s (between 1992 and 2002) and 2000s (between 2003 and 2010). The clinical characteristics of patients were studied and compared between the groups. A total of 2498 (974 in 1990s and 1524 in 2000s) renal biopsies was done during the 19-year period. The incidence of amyloidosis in 1990s and 2000s was 1.74% (n = 17) and 1.9% (n = 29), respectively (p > 0.05). We noted that the incidence of renal amyloidosis increased significantly (p < 0.05) among the females in 2000s. The mean age of patients in 2000s and 1990s was 38 ± 17.9 and 39.2 ± 19 years, respectively (p = 0.83). Renal insufficiency in patients with renal amyloidosis significantly increased (p < 0.05) in 2000s (n = 14; 48.2%) in comparison to 1990s (n = 2; 12.8%). Subnephrotic proteinuria was observed in 12.8% (n = 2) and 48.82% (n = 14) of patients in 1990s and 2000s, respectively (p < 0.05). Infection (n = 10; 58.8%) was the most common cause of secondary amyloidosis during the 1990s, whereas chronic inflammation (n = 14; 48.2%) was the most common cause in 2000s. In 1990s, the incidence of ankylosing spondylitis (AS) and rheumatoid arthritis (RA) was 11.7% (n = 2) and 5.8% (n = 1), respectively, but in 2000s, their respective incidence was 17.2% (n = 5) each. Multiple myeloma (MM) was the most common cause of amyloid light chain protein (AL) amyloidosis in both the groups. We observed systemic lupus erythromatosus (SLE)-related renal amyloidosis in two cases and Hodgkin lymphoma-associated amyloidosis in one case in 2000s. The overall incidence of renal amyloidosis showed little change from 1990s to 2000s. Chronic inflammatory diseases were the most common cause of renal amyloidosis in 2000s in contrast to infections in 1990s. Female gender was more affected in 2000s than in 1990s. Renal insufficiency and subnephrotic-range proteinuria were more frequent clinical manifestations of renal amyloidosis in recent years (2000s) in comparison to the earlier decade (1990s).

All adult patients of laboratory-proven malaria with acute kidney injury (AKI) admitted during the period of May 2010 to June 2011 were included. Patient characteristics, physical examination findings, and laboratory parameters were recorded. Patient outcome was assessed in terms of peak serum creatinine level, duration of hospital stay, need for dialysis, and in-hospital mortality rate. Surviving patients were followed up for 3 months to determine progression to chronic kidney disease. This study enrolled 101 patients of malarial AKI. Mean age was 33.70 ± 15.39 years. Oliguric AKI was observed in 44.6% cases. Mean duration of hospital stay was 8.75 ± 7.60 days. Renal replacement therapy was required in 36.6% patients. Ten (9.9%) patients succumbed to illness during hospital stay. Majority of deaths occurred shortly after admission. Mortality risk was significantly associated with raised LDH (p = 0.019), lower hemoglobin level (p = 0.015), raised aspartate transaminases (p < 0.001), and elevated alanine transaminases (p = 0.016). Cerebral malaria was an important determinant of mortality (p = 0.002). Renal parameters, including severity of renal dysfunction and need for dialysis, were not associated with mortality risk. Among 91 survivors, 79 patients completed a 3-month follow-up and all of them had normalization of renal function. We observed 9.9% in-hospital mortality rate in the study cohort. Cerebral malaria was an important risk factor for mortality in malarial AKI patients. Severity of renal dysfunction did not correlate with the mortality risk in our study.
