ALFONSO VALDES, María Elena et al. Alloimmunization against blood cells in the first trimester of pregnancy. Rev Cubana Hematol Inmunol Hemoter [online]. 2006, vol.22, n.2. ISSN 0864-0289.
A prospective study was conducted to know the prevalence of alloimmunizations against blood cells in 30 nulliparous young women without previos history of blood transfusions or spontaneous abortions that underwent induced abortion before the 12 weeks of gestation. The presence of alloantibodies against erythrocytic , leukocytic and platelet antigens was determined before and 6 months after abortion. No erythrocytic antibodies were detected in any case. In the initial study, antibodies against leukocytes and/or platelets were detected in 30 % of the cases, and 6 months after abortion in 33.33 %. On characterizing the antibodies in the initial sample, it was determined that 16.66 % of the women had anti-HLA antibodies, whereas 13.33 % had granulocyte-specific antibodies. In the final sample, 13.33 % had anti-HLA, 16.66 % had granulocyte-specific and 3.33 % platelet-specific antibodies. No relation was found between the number of pregnancies and the presence of alloantibodies
