BENCOMO HERNANDEZ, Antonio A et al. Autoantibodies in hematologic patients treated with Alpha-interferon. Rev Cubana Hematol Inmunol Hemoter [online]. 2000, vol.16, n.1, pp. 49-55. ISSN 1561-2996.

Presence of autoantibodies in 45 patients with hematologic diseases was studied: 32 cases of chronic myeloid leukemia (CML) and 13 cases of other lymphoproliferative diseases (LPD). All cases of LPD and other 20 of CML, were treated with natural Alpha-interferon (IFN) or recombinant Alpha 2b, when study was performed. Mean length of treatment was of 27 months (1-96), and mean dosis given was of 3 millions, three times a week. Erythrocitic autoantibodies were found in 16 cases (80%) where CML was treated with IFN, but neither in 4 patients given IFN nor in non treated patients groups. In 5 cases (26%) given IFN, and in other two (12%), without treatment, other types of autoantibody were found. In cases with autoantibodies there weren´t manifestations of autoimmune hemolytic anemia (AHA) or of other autoimmune diseases. In cases with LPD, we found autoantibodies and antinuclear in 2 (14,3%). In a case of Hodgkin´s disease, AHA was diagnosed within 10 weeks of IFN-treatment
