1Shandong University Jinan 250100, P. R. China ; Department of Nephrology, People's Hospital of Dong E county Liaocheng 252200, People's P. R. China.
A 15-year-old boy with glomerulonephritis achieved complete remission of proteinuria with supportive care alone. Persistent low complement levels (C3 and C4) were observed during follow-up.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- A 15-year-old male presented with anasarca, indicating significant fluid retention.
- Laboratory results showed proteinuria, hematuria, and hypocomplementemia, suggesting kidney involvement.
Observation:
- Renal biopsy revealed diffuse mesangial and endocapillary proliferative glomerulonephritis.
- Immunofluorescence demonstrated IgG, IgA, C3, C1q, and F deposition in capillary walls and subendothelial areas.
- Electron microscopy identified subendothelial electron-dense deposits and foot process effacement.
Findings:
- The patient achieved complete remission of proteinuria within one month of supportive treatment.
- Microscopic hematuria persisted throughout the 62-week follow-up period.
- Serum complement C3 and C4 levels remained persistently low, despite clinical improvement.
Implications:
- This case highlights the potential for spontaneous remission in certain forms of glomerulonephritis.
- Persistent hypocomplementemia may not always correlate with active disease or predict poor outcomes.
- Further research is needed to understand the long-term significance of persistently low complement levels in resolved glomerulonephritis.
