Interferon-beta-1b induced autoimmune hemolytic anemia in a patient with ms : a case report

الملخص EN

A 26-year-old lady with the diagnosis of multiple sclerosis who had received interferon beta1-b for eleven months was visited in MS clinic of our hospital because of icter and fatigue.

Laboratory tests showed anemia, indirect hyperbillirubinemia, increased LDH, positive direct and indirect coomb’s tests, and increased reticulocyte count and percentage.

Other causes of autoimmune hemolytic anemia (AHA) and pre-existing AHA in the patient were ruled out.

After INF discontinuation, symptoms disappeared, hemoglobin increased, and indirect coomb’s test became negative.

We concluded that autoimmune hemolytic anemia should be considered in all MS patients who receive interferon beta1-b and present with symptoms and signs of anemia.
