Clinical Spectrum of Acute Post-streptococcal Glomerulonephritis in Children: A Kashmir Experience.

Background In the pediatric population, acute post-streptococcal glomerulonephritis (PSGN) is a common glomerular etiology of hematuria and acute hypertension leading to hospitalization. We conducted this study to know the clinical profile and occurrence of acute PSGN in patients presenting with features of acute nephritic syndrome. Methods This prospective observational study was conducted on children aged between two and 18 years, presenting with clinical features of acute glomerular nephritis (AGN). After due ethical considerations, all eligible patients were enrolled and underwent detailed clinical assessment, laboratory, and imaging evaluation, followed by protocolized treatment. Relevant data were collected and analyzed to reach valid results. Results Out of 60 patients with AGN, PSGN was found in 83.3% of the patients (50/60). The age group under five years was the most commonly involved, with a male/female ratio of 1.6:1. Around half of the studied patients were from the lower middle class, and 40 (80%) were from rural backgrounds. Facial puffiness was the most common clinical presentation, seen in 45 (90%) patients. Hypocomplementemia and proteinuria were seen in all PSGN patients. Pyoderma was the most common preceding infection, seen in 38 (76%) patients, followed by pharyngitis. Acute kidney injury (AKI) was the most common complication, seen in 12 (24%) patients. Complete resolution of the signs and symptoms was seen in 37 (74%) patients at the time of discharge, which increased to 47 (94%) patients at six months post discharge. Conclusion PSGN stands to be the most common cause of pediatric AGN. The population under five years of age, with a past history of pyoderma, is more predisposed to PSGN. The potential for the occurrence of AKI and other life-threatening complications is high, for which early diagnosis and institution of proper treatment would be very beneficial.
