RESUMO
OBJECTIVES: To investigate the etiologies and outcomes of rapidly progressive glomerulonephritis (RPGN) in pediatric patients at King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia. METHODS: A retrospective study was conducted in 19 pediatric patients who were diagnosed with RPGN between 2006 and 2016 at the Department of Pediatric Medicine at KAUH. Associations between variables were evaluated using independent t-test, one-way analysis of variance (ANOVA) and Chi-squared tests. RESULTS: Majority of patients were male, (68.4%), with a mean±SD age at diagnosis of 8.52±3.15 years. The most common underlying etiologies were post-infectious glomerulonephritis (PIGN) (63.2%) and lupus nephritis (21.1%). Thirteen patients exhibited a good clinical prognosis (68.4%), with 6 exhibiting a poor prognosis (31.6%), 4 of whom progressed to end-stage renal disease (ESRD), one experiencing a relapse and one developing chronic kidney disease. Post-infectious glomerulonephritis was associated with the best clinical outcome overall. Treatment was implemented early in most patients and continued for 3 months. Among the 19 patients, 2 died and one underwent hemodialysis. CONCLUSION: Post-infectious glomerulonephritis was the most common etiology of RPGN, with these patients achieving a good clinical prognosis overall. Early identification and treatment of RPGN is important to preserve renal function, which is a key factor for achieving a good prognosis.
