Hyercalcemia induced by interferon therapy in chronic hepatitis C.

ABSTRACT

Interferon is being increasingly used in the treatment of chronic hepatitis C. Several case reports have suggested an association between interferon therapy and sarcoidosis with hypercalcemia. We report a case of severe hypercalcemic crisis with bilateral hilar lymphadenopathy in a male patient who was receiving interferon therapy for hepatitis C. Gastroenterologists should be aware of this unusual but clinically important complication of interferon therapy.
