title: Transient IgA nephropathy with acute kidney injury in a patient with dengue fever.
abstract: Dengue virus infection can clinically manifest as dengue fever, dengue shock syndrome and dengue hemorrhagic fever. Acute kidney injury as a result of dengue virus infection can occur due to various reasons including hypotension, rhabdomyolysis, sepsis and rarely immune complex mediated glomerular injury. However, glomerulonephritis associated with IgA Nephropathy in dengue virus infection has not been reported previously. We report a case of 15-year-old boy who was admitted with dengue fever and dialysis dependant acute kidney injury. Urine examination showed microscopic glomerular hematuria and proteinuria. Kidney biopsy showed mesangial proliferation with mesangial IgA dominant immune complex deposits and acute tubular necrosis. A repeated kidney biopsy 6 weeks after clinical recovery showed reversal of glomerular changes as well as resolution of mesangial IgA deposits.
