The Clinicopathological Correlation and Outcome of Glomerulonephritis With Crescent: A Single-Center Study.

BACKGROUND: There is a lack of standardized treatments for patients with less than 50% crescents observed in their renal biopsies. This study aimed to analyze the crescent percentage, clinicopathological characteristics, and renal prognosis of glomerulonephritis (GN) cases with at least one crescentic lesion. MATERIALS AND METHODS: This retrospective cohort study was conducted at the Indira Gandhi Institute of Medical Sciences, Patna, from January 2016 to December 2020. Consecutive patients (aged between 18 and 65 years) with renal biopsy findings suggestive of GN and at least one crescent were included in the study. Demographic details and clinical presentation were collected from the medical records. RESULTS: A total of 145 patients were included. The mean (standard deviation (SD)) age was 33.06 (11.739) years. Hemoptysis was significantly higher in the ≥50% crescent group (P=0.011). Rapidly progressive glomerulonephritis (RPGN) was significantly higher in the ≥50% crescent group (P<0.001). There was a significant difference observed in mean creatinine (P=0.001), mean crescents (P<0.001), and mean urine polymerase chain reaction (PCR) (P=0.031). Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis was significantly higher in the ≥50% crescent group (P<0.001). Complete remission decreased as crescents increased. In GN with crescent, the presence of fibrous crescents (≥50%) is associated with a higher rate of treatment resistance (100%) compared to fibrocellular (58.33%) and cellular crescents (6.25%). In the ≥50% crescent group, death was significantly higher in patients with fibrous crescent age (57.14%). CONCLUSION: Crescent percentage and crescent age were found to be significantly related to greater risk of renal failure and resistance to treatment.

Minimal change disease (MCD) following vaccination with ChAdOx1 nCoV-19 vaccine in a young Indian male: A case report.

Various vaccines against coronavirus disease 2019 (COVID-19) have been developed amidst the ongoing pandemic. Few cases of glomerulonephritis after COVID-19 vaccination have been reported globally. We present a case of nephrotic syndrome due to minimal change disease (MCD) most likely associated with the ChAdOx1 nCoV-19 vaccine. A 24-year-old male presented with anasarca and frothy urine after receiving the first dose of the COVID-19 vaccine. On admission, the patient had normal serum creatinine with 24-h urinary protein excretion of 4.1 g/day and severe hypoalbuminemia. Kidney biopsy revealed nonproliferative glomerular morphology with relatively unremarkable-appearing glomeruli on light microscopy and diffuse effacement of the odocyte foot processes on electron microscopy, consistent with diagnosis of MCD. This case highlights the risk of new-onset nephrotic syndrome due to MCD after COVID-19 vaccination.

Acute kidney injury with consumption of raw gall bladder of Indian carp fish (Labeo rohita): A single center study from India.

AIM: This retrospective study examined the clinical presentation and outcome of all patients who presented with acute kidney injury (AKI) following consumption of uncooked fish gallbladder as folk medicine. METHODS: We reviewed all cases admitted at our institute between 1 January 1997 and 31 December 2016 following ingestion of fish gallbladder (Indian carp/Labeo rohita). RESULTS: A total 32 of patients were included, with a male: female ratio of 3:1 and mean age 44.34 ± 13.33 years. The mean number of gall bladder consumed was 4.59 ± 4.75. All 32 patients presented with hepatic and renal failure. The mean duration of onset of symptoms following ingestion was 6.47 ± 2.84 h. At the time of admission, urine output was 187.9 ± 141 mL/24 h, serum creatinine 11.66 ± 2.50 mg/dL, serum bilirubin 6.14 ± 3.91 mg/dL, serum glutamate-pyruvate transaminase (SGPT) 687 ± 458 IU/L and serum glutamic oxaloacetic transaminase (SGOT) 188 ± 181 IU/L. All but one patient required haemodialysis. Twenty-seven patients were discharged with recovering acute kidney injury while five patients died. Mean duration of hospital stay was 12.94 ± 8.31 days. Mean number of haemodialysis sessions received by patients was 4.59 ± 3.12. Interval between consumption and onset of symptoms, serum bilirubin and SGPT were found to be significantly different between those who survived and died. CONCLUSION: Acute kidney injury associated with ingestion of raw fish gallbladder is associated with significant morbidity and mortality.

Analysis of native kidney biopsy: Data from a single center from Bihar, India.

This is a retrospective study of all native kidney biopsies performed at our center between October 1, 2012 and March 31, 2015. Relevant clinical and laboratory variables were recorded. Biopsy samples were processed for light microscopy and immunofluorescence in all cases. Histological classification was adapted from the World Health Organization recommendations. The indications for kidney biopsy were nephrotic syndrome in adults in 190 cases, rapidly progressive renal failure in 43, unexplained renal failure in 25, and steroid-resistant nephrotic syndrome in children in 12. The mean age of the patients was 31.48 ± 13.46 years. Male-to-female ratio was 1.87:1. Mean serum creatinine (SCr) of the patients was 2.36 ± 2.07 mg/dL. Primary glomerulonephritis accounted for 88.89% of cases (240) while secondary glomerulonephritis accounted for 7.40% of total cases (20). Interstitial disease accounted for 1.5% and vascular disease for 2.2%. The most common lesion among primary glomerulonephritis was focal segmental glomerulosclerosis (FSGS) (31.11%) followed by diffuse proliferative glomerulonephritis (DPGN) (13.33%) and membranous glomerulonephritis (MGN) (12.59%). Among secondary glomerulonephritis, lupus nephritis was the most common (5.56%). In patients with SCr 1.4 mg/dL or less (n = 131), FSGS was the most common histology (17.26%) followed by MGN (23.66%) and minimal change disease (7.63%). Whereas, in patients with SCr more than 1.4 mg/dL (n = 139), DPGN was the most common diagnosis (23.74%) followed by FSGS (17.26%) and IgAN (12.23%). Fourteen patients (5.2%) had one or more episode of gross hematuria, three of whom required blood transfusion. The overall FSGS was the most common lesion seen. When we consider only patients with deranged renal function, DPGN was the most common histopathological lesion. The reason for disproportionate high incidence for DPGN is not clear and requires further research.
