Abstract
Background
Acute post-streptococcal glomerulonephritis (APSGN) is common in developing countries with a high hospitalization rate. Most patients have acute nephritic syndrome features, although some occasionally present with unusual clinical features. This study aims to describe and analyze clinical features, complications, and laboratory parameters in children diagnosed with APSGN at presentation, 4 and 12 weeks later, in a resource-limited setting.
Methods
This cross-sectional study was conducted among children < 16 years with APSGN between January 2015 and July 2022. Hospital medical records and outpatient cards were reviewed for clinical findings, laboratory parameters, and kidney biopsy results. Descriptive analysis of multiple categorical variables was performed using SPSS version 16.0 and presented as frequencies and percentages.
Results
The study included 77 patients. Most (94.8%) were older than five years, and age group 5–12 years had highest prevalence (72.7%). Boys were affected more frequently than girls (66.2% vs. 33.8%). Edema (93.5%), hypertension (87%), and gross hematuria (67.5%) were the most frequent presenting symptoms, and pulmonary edema (23.4%) was the most common severe complication. Anti-DNase B and anti-streptolysin O titers were positive in 86.9% and 72.7%, respectively, and 96.1% had C3 hypocomplementemia. Most clinical features resolved in three months. However, at 3 months, 6.5% of patients had persistent hypertension, impaired kidney function, and proteinuria alone or in combination. Most patients (84.4%) had an uncomplicated course; 12 underwent kidney biopsy, 9 required corticosteroids, and 1 required kidney replacement therapy. There was no mortality during the study period.
Conclusion
Generalized swelling, hypertension, and hematuria were most common presenting features. Persistent hypertension, impaired kidney function, and proteinuria persisted in a small proportion who had a significant clinical course and required kidney biopsy.
