Acute renal failure in a patient with acute lymphoblastic leukemia : a rare cause

الملخص EN

A young adult was diagnosed to have acute lymphoblastic leukemia, T-cell immunophenotype and was initiated on chemotherapy.

He presented with acute renal failure two days after the completion of his induction regimen.

A renal biopsy showed features of necrotizing crescentic glomerulonephritis (GN).

Serology for c-anti-neutrophil cytoplasmic antibody (ANCA) was positive and a final diagnosis of ANCA-associated necrotizing crescentic GN was made.

Aggressive immunosuppression could not be used due to the presence of nosocomial pneumonia and the patient expired 26 days after the renal biopsy diagnosis.

We report for the first time the association of acute lymphoblastic leukemia with crescentic GN and, hence, expand the list of malignancy-related ANCA-positive GN.
