Abstract:
PURPOSE: This retrospective study has been undertaken to find out the clinical outcome of children with HS nephritis and its relationship with initial clinical presentation and/or renal pathologic finding. PATIENTS AND METHODS: Study population consisted of 59 children with HS nephritis who have been admitted to the Pediatric department of KyungPook University Hospital from 1987 to 1999, and biopsy was done with indications of heavy proteinuria ( > 1 g/m2/day ) lasting over 1 month, nephrotic syndrome, and persistent hematuria and/or proteinuria over 1 year. Patients were divided clinically into 3 groups ; isolated hematuria, hematuria with proteinuria and heavy proteinuria (including nephrotic syndrome). Biopsy findings were graded from I-V according to International Study of Kidney Disease in Children (ISKDC). RESULTS: Mean age of presentation was 8.1+/-3.0 years and slight male proponderance was noted ( 33 boys and 26 girls ). Histopathologic grading showed Grade I ; 2, Grade II ; 44, and Grade III ; 13 cases. Clinical outcome at the follow-up period of 1-2 years (49 cases) and 3-4 years (30 cases) showed normal urinalysis in 15 ( 30.6% ) and 18 cases ( 60.0%), persistent isolated hematuria in 20 ( 40.8% ) and 2 cases ( 6.7 % ), hematuria with proteinuria in 11 ( 22.5% ) and 8 cases ( 26.6% ), and persistent heavy proteinuria in 3 ( 6.1% ) and 2 cases ( 6.7% ) respectively. Clinical outcome according to histopathologic grading showed the frequency of normalization of urinalysis being lower in Grade III compared to grade I or II. Clinical outcome according to initial clinical presentation showed no relationship to the normalization of urinalysis at follow-up periods. However, 15-20% of children with initial heavy proteinuria showed persistent heavy proteinuria ( 3 out of 20 cases at 1-2 years, and 2 out of 10 case at 3-4 years of follow-up periods). CONCLUSION: The majority of children with HS nephritis (histopathologic grade I, II, III) improved within 3-4 years, and persistent heavy proteinuria was seen only in a few of children with initial clinical presentation of heavy proteinuria.
