title: Outcome results in children with IgA nephropathy: a single center experience.
abstract: BACKGROUND
  Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis. Patients manifest variable clinical symptoms (eg, microhematuria) with preserved or progressive deterioration of renal function resulting in end-stage renal disease. The aim of this study was to evaluate patients from a single center to describe the clinical features, treatments, and follow-up results of those with the disease.
  
  
  METHODS
  This is a retrospective data study of all children with IgAN. Patients who had a histopathologically proven diagnosis of IgAN and were followed up for at least 5 years were included in the study. Renal biopsy, graded as Hass classification, was performed on all patients. A total of 39 patients were included in the study.
  
  
  RESULTS
  The mean follow-up time (± standard deviation) was 10.4 ± 3.51 (range 5-16) years. Twenty-nine patients (74.4%) were male and ten (25.6%) were female. Nineteen (48.7%) patients presented with recurrent macroscopic hematuria, ten (25.6%) with microscopic hematuria ± proteinuria, six (15.4%) with nephritic syndrome, and four (10.3%) with nephrotic syndrome. All patients underwent a renal biopsy, which was graded according to the Hass classification. At the end of follow-up time, 18 (46.1%) patients were normal, 15 (38.5%) had minor urinary abnormalities, three (7.7%) had active renal disease, and three (7.7%) developed renal failure.
  
  
  CONCLUSIONS
  The results of the present study are better than those from most other series. The majority of children with IgAN in this study were admitted with recurrent macroscopic hematuria and found to have a good prognosis. We suggest that children with IgAN have a good prognosis in the first 5-year follow-up period.
