Hepatitis B mediated glomerulonephritis in children
Insights
Hepatitis B virus-mediated glomerulonephritis (GN) in children is often self-limiting, with membranous GN being most common. Treatments like immunosuppressants did not alter the disease course, though liver issues persisted.
Area of Science:
- Pediatric Nephrology
- Hepatology
- Virology
Background:
- Hepatitis B virus (HBV) infection is a significant cause of glomerulonephritis (GN) in children.
- Understanding the clinical course and outcomes of HBV-mediated GN is crucial for effective management.
Purpose of the Study:
- To analyze the clinical characteristics, histological findings, and outcomes of HBV-mediated glomerulonephritis in a pediatric cohort.
- To evaluate the efficacy of immunosuppressive therapy and indomethacin in managing this condition.
Main Methods:
- Retrospective observational study of 49 children diagnosed with HBV-mediated GN over 11 years.
- Analysis of demographic data, clinical presentation, kidney biopsy findings (membranous, mesangiocapillary, mesangial proliferative GN), and treatment outcomes.
- Assessment of disease self-limiting nature and persistence of liver disease post-GN resolution.
Main Results:
- Boys (38:11 ratio) and young infants (1-5 years) were predominantly affected.
- Membranous GN was the most common histological type (77%), followed by mesangiocapillary GN (18%) and mesangial proliferative GN (5%).
- The disease was self-limiting in most cases, with no significant modification of course or outcome by immunosuppressive drugs or indomethacin. Liver disease often persisted after GN resolution.
Conclusions:
- HBV-mediated glomerulonephritis in children typically follows a self-limiting course, predominantly presenting as membranous nephropathy.
- Standard treatments do not appear to alter the renal disease's outcome, highlighting the importance of supportive care.
- Persistent liver disease post-glomerulonephritis resolution warrants continued monitoring in affected children.
Abstract:
Forty nine children with hepatitis B virus-mediated glomerulonephritis (GN) were observed during the last 11 years. Boys were more frequently affected than girls, the ratio being 38 : 11. Young infants (1 to 5 years of age) predominated in the group. The incidence of membranous form of glomerulonephritis was high (34 out of 44 kidney biopsy cases, 77%), the rest of patients showing mesangiocapillary GN-8 (18%) and mesangial proliferative GN-2 (5%). The disease proved to be self limiting. Immunosuppressive or indomethacin treatment did not modify the course and outcome of the disease. Liver disease in these patients often persisted after the resolution of glomerulonephritis.
