Summary
This case report details the first documented instance of IgA nephropathy (IgAN) in a Nigerian male presenting with nephrotic syndrome. Early steroid treatment showed promise, but relapse and renal function decline highlight diagnostic challenges.
Area of Science:
- Nephrology
- Immunology
- Genetics
Background:
- Nephrotic syndrome is a kidney disorder characterized by heavy protein in the urine.
- IgA nephropathy (IgAN) is a common cause of primary glomerulonephritis worldwide.
- Limited data exists on IgAN prevalence in Sub-Saharan Africa.
Observation:
- A 20-year-old Nigerian male presented with nephrotic syndrome and normal renal function.
- Renal biopsy confirmed IgA nephropathy (IgAN).
- Initial response to steroid therapy was observed.
Findings:
- The patient experienced a relapse of nephrotic syndrome with significant renal function deterioration 2 years later.
- This represents the first documented case of IgAN in a Nigerian individual.
- The low rate of renal biopsies in the region may lead to underdiagnosis of IgAN.
Implications:
- Highlights the potential underdiagnosis of IgA nephropathy in Nigeria.
- Emphasizes the need for increased renal biopsy rates for accurate diagnosis.
- Suggests IgAN may be a more significant contributor to kidney disease in the region than previously thought.
