Leukocytoclastic vasculitis associated with bortezomib therapy

الملخص EN

A 28-year-old male, 10 years post live-related renal transplant with stable graft function of 1.4 mg/dL, presented with complaints of loss of appetite and vomiting for three days.

On evaluation, he was found to have significant graft dysfunction with a creatinine of 10.3 mg/dL.

He was initiated on hemodialysis in view of uremic gastrointestinal symptoms.

Graft biopsy done revealed acute cell-mediated rejection BANFF IIB and diffuse C4d-positive antibody-mediated rejection.

He was treated with intravenous methylprednisolone, therapeutic plasma exchange, and intravenous immunoglobulin therapy, following which his graft function improved gradually.

He received multiple injections of bortezomib as a part of anti-rejection treatment protocol and developed peripheral neuropathy, leukocytoclastic vasculitis, and varicellosis.

This case report is to highlight the unusual phenomenon of leukocytoclastic vasculitis in a post renal transplant setting secondary to bortezomib therapy.
