Association of HLA-DR5 with recurrent spontaneous abortion in women treated with paternal leukocytes. Possible subclinical autoimmune disease

Abstract

The incidence of pregnancy loss is higher in patients with various autoimmune diseases than in the general population. The causes of recurrent spontaneous abortions (RSA) are unknown; however, the presence of antinuclear antibodies and other antibodies in some women with RSA who are otherwise healthy suggests the possibility of underlying autoimmune disease. Because autoimmune diseases are often associated with an increased incidence of certain histocompatibility antigens, we examined the occurrence of specific HLA antigens in patients who had been treated for RSA. We found HLA-DR5 to be significantly overrepresented in the patients with RSA who aborted again after treatment with paternal mononuclear cell immunotherapy, compared with the incidence of this phenotype in a control population. Neither antinuclear antibodies nor antilymphocyte antibodies segregated with DR5. However, DR5+ patients who developed antilymphocyte antibodies after immunotherapy were more likely than all other treated patients to experience subsequent abortion (P less than 0.01). Our findings suggest the possibility of an underlying autoimmune disease in these women.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
