We describe conduction block as an unusual electrophysiologic manifestation in a patient with necrotizing angiopathy. The patient developed subacute symptoms over a 1-month period consisting of progressive pain, tingling, and weakness of the lower extremities. Physical examination revealed a pattern consistent with a polyneuropathy. Electrodiagnostic studies provided evidence of a conduction block in the left ulnar nerve. Pathologic studies confirmed the process to be a necrotizing angiopathy. This report establishes the role of conduction block in human nerve ischemia.

Interferon-alpha and ribavirin are widely used treatments for chronic hepatitis C. It is believed to be a cytokine made by T lymphocytes upon activation by foreign antigens. Complications of interferon and ribavirin therapy include systemic flulike symptoms, marrow suppression, emotional liability, auto immune reactions (especially auto immune thyroiditis) and miscellaneous side effects such as alopecia, rashes, diarrhea, numbness, and tingling of the extremities. With the possible exception of autoimmune thyroiditis, all these side effects are reversed upon dose lowering or cessation of therapy. We report a case of a 51-year-old man, with no previous history of vascular disease, who developed ischemic colitis after interferon-alpha and ribavirin therapy for chronic hepatitis C. In the literature, there have been only 2 published accounts associating interferon-alpha use with ischemic colitis in 2 patients. This report illustrates a better association of interferon-alpha and ribavirin with ischemic colitis.
