ABSTRACT

Purpose: This study aimed to compare the clinical outcome of acute poststreptocaccal glomerulonephritis (APSGN) between patients who had presented with gross hematuria and those with microscopic hematuria.
Methods: Thirty-nine patients with acute poststreptococcal glomerulonephritis, who were diagnosed from January 2000 to April 2003 were enrolled.
Results : The mean age was 8.85 years and the male to female ratio was 1.1:1 Seventeen patients presented with gross hematuria at diagnosis(group A) and twenty-two patients had microscopic hematuria only(group B). There were no significant differences between the two groups in the incidence of edema, fever or history of respiratory infection and oliguria. But hypertension was more frequent in group B. Laboratory data showed decreased C3 and C4 level in group B. Spot urine protein/creatinine ratio and 24hr urine protein showed higher levels in group A. Conclusion; Patients with gross hematuria at diagnosis had lower incidence of hypertension and a higher rate of nephrotic range of proteinuna than patients with microscopic hematuria. However, no difference in the duration of admission or complication rate was observed. All patients had clinical improvement during follow-up. We conclude that gross hematuria is not a significant prognostic factor for poststreptococcal glomerulonephritis.
