Autoimmune haemolytic anaemia and thyroiditis:case report

A 55-year-old woman developed autoimmunehaemolytic anaemia and thyroiditis during treatment withpeginterferon-α-2a for chronic hepatitis C.

The woman started receiving ribavirin and SCpeginterferon-α-2a 180 µg/week in February 2010. After8 weeks, she developed haemolytic anaemia. Due tohaemoglobin reduction, 16 weeks after treatment, shestarted receiving erythropoietin; however, no improvementwas noted. Gradual withdrawal of ribavirin was started, andanaemia failed to reverse. At week 28 she receivedlevothyroxine sodium for overt hypothyroidism. Shepresented during week 35, with easy fatigability andsyncope. Bone marrow examinations revealedhypercellular erythroid series. Her thyroglobulin antibodyand thyroid peroxidase antibody levels were 60.8/40 IU/mLand 48.9/34 IU/mL, respectively. Peginterferon-α-2a-induced autoimmune haemolysis was diagnosed.

Peginterferon-α-2a was discontinued, but haemolysisand hypothyroidism progression did not cease. Six weeksafter steroid induction, the woman’s haemoglobin and TSHlevels had normalised, and antithyroid antibodies becamenegative.
