RESUMO
AIM: Post-streptococcal glomerulonephritis (PSGN) is a frequent cause of acute nephritis in children. This study aimed to describe the epidemiology, clinical characteristics and outcomes of PSGN and look for predictor's factors of severity. METHODS: A 12-year retrospective review of case notes and laboratory data was conducted at a department of pediatrics, pediatric emergency and intensive care, Hedi Chaker Hospital. RESULTS: One hundred seventy eight children were treated for PSGN with a mean age of 7.6 ans±3.43 ans. One hundred and forty-two patients (80%) had a history of a recent upper respiratory tract or skin infection. Streptococcal pharyngitis was the most common cause, identified in 113 patients (67.6%). Macroscopic hematuria and edema were noted in 135 (75.8%) and 114 cases (64%) respectively. Hypertension was present in 55 patients (31%). Oliguria was noted in 30 children (16.8%). Sixty-six subjects (37%) developed acute renal impairment (creatinine≥70 micromoles/L). No correlation was demonstrated between acute renal impairment and age, sex, triggering infection, anemia and white blood cell count. Creatinine greater than 56.35 micromoles/L was associated with a high risk of developing high blood pressure. The mean length of admission was 5.8 days±4.44. Only one subject has ongoing renal dysfunction. CONCLUSION: PSGN remains a common nephropathy in our region. The detection and effective treatment of any infection that may be involved can reduce the incidence of this disease.
