BackgroundThe epidemiology of acute kidney injury (AKI) differs from country to country and varies from center to center within a country. Owing to the absence of a central registry, data on overall epidemiology of AKI are scanty from India.MethodsThis study aimed at describing changes in epidemiology of community-acquired AKI (CAAKI) over a time span of 26 years in two study periods, namely, 1983-95 and 1996-2008.ResultsWe studied 2405 (1375 male and 1030 female) cases of AKI in the age range 1-95 (mean: 40.32) years. The incidence of CAAKI in 1983-95 and 1996-2008 was 1.95 and 4.14 per 1000 admission, respectively (P < 0.01). Obstetrical AKI has decreased because of the declining number of post-abortal AKI. Surgical AKI decreased from 13.8% in 1983-95 to 9.17% in 1996-2008(P < 0.01). Malarial AKI increased significantly from 4.7% in the first half of the study to 17% in the later period (P < 0.01). Diarrhea-associated AKI had significantly decreased from 36.83% in 1983-95 to 19% in 1996-2008 (P < 0.01). Sepsis-related AKI had increased from 1.57% in 1983-95 to 11.43% in 1996-2008 (P < 0.01). Nephrotoxic AKI showed an increasing trend in recent years (P < 0.01) and mainly caused by rifampicin and NSAIDs. Liver disease-related AKI increased from 1.73% in 1983-95 to 3.17% in 1996-2008 (P < 0.01). Myeloma-associated acute renal failure (ARF) accounted for 1.25% of the total number of ARF cases in the period 1996-2008. HIV infection contributed to 1.65% of ARF of the total number of AKI cases in the second period (1996-2008). Incidence of renal cortical necrosis (RCN) decreased significantly from 5.8% in 1983-95 to 1.3% in 1996-2008 of the total number of ARF cases (P < 0.01). However, during the same period ARF due to acute tubular necrosis, acute glomerulonephritis and acute interstitial nephritis remained unchanged. The mortality rate from AKI decreased significantly from 20% in 1983-95 to 10.98% in 1996-2008 (P < 0.01).ConclusionsThe epidemiological characteristics of CAAKI have changed over the past three decades. There has been an increase in the overall incidence of ARF with the changing etiology of AKI in recent years. Incidences of obstetrical, surgical and diarrheal AKI have decreased significantly, whereas those of AKI associated with malaria, sepsis, nephrotoxic drugs and liver disease have increased. RCN has decreased significantly. In contrast to developed nations, community-acquired AKI is more common in developing countries. It often affects younger individuals and is caused by single and preventable diseases. © 2013 The Author.

Recent data regarding the clinical and histopathologic spectrum of crescentic glomerulonephritis (CSGN) among the Indian adult population is unknown. 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.

Background From developing countries, there is paucity of information regarding epidemiological characteristics of acute-on-chronic renal failure (ACRF) that differs from acute kidney injury (AKI). Methods In this prospective study, we analyzed and compared clinical characteristics and outcome of ACRF with AKI from January 2007 to August 2012. Results A total of 1117 patients with community-acquired AKI were included in study (AKI = 835; ACRF = 282). Patients with ACRF were older than patients with AKI (p < 0.001). Sepsis was the main cause of acute decline in renal functions in patients with ACRF in comparison to AKI (p < 0.001). Volume depletion/renal hypoperfusion was the most common cause of AKI and the difference was statistically significant as compared to ACRF (33.9% vs. 17.7%; p < 0.001). Need for dialysis was significantly less in patients with ACRF as compared to AKI (68% vs. 77.4%; p 0.002). Lower inhospital mortality was observed in ACRF in comparison to AKI (5% vs. 8.9%, p = 0.04), while no significant difference was noted in terms of duration of hospital stay between the two groups (p = 0.67). However, a significantly higher proportion of patients with ACRF did not recover and progressed to end-stage renal disease as compared to AKI (20% vs. 7.8%; p < 0.001). Conclusion ACRF constituted an important cause (25%) of AKI. An episode of superimposed AKI is associated with significantly increased risk of progression to end-stage renal disease in patients with chronic kidney disease.
