Case in brief
A teenage refugee presented with rapidly progressive renal failure, nephrotic-range proteinuria, and fluid overload necessitating haemodialysis. He had chronic perianal sepsis and developed a methicillin-resistant Staphylococcus aureus urinary infection during hospitalization. Kidney biopsy revealed IgA-dominant crescentic glomerulonephritis with significant chronic damage. Due to the active infection and severe kidney damage, immunosuppression was not administered, and kidney function did not recover despite clearing the infection.
Diagnostic / clinical pearl
Clinicians should consider the complexities of diagnosing IgA-IRGN versus advanced IgAN in the context of active infections, particularly when significant renal damage is present.
Why it matters
This case underscores the importance of weighing the risks of immunosuppression against the potential for kidney recovery in patients with concurrent infections and severe renal pathology.
