Managing a Pregnancy in the Presence of the Rare Blood Group Antibody PP1Pk.

Pregnant women with p phenotype, who lack antigens P, P1, and Pk, spontaneously form anti-PP1Pk antibodies whose primary target is the placenta. The risk of miscarriage in these women is 50%-70% and reaches 87% in the second trimester. The therapies aim to reduce the titer of antibodies early in pregnancy. They also have risk of hemolytic transfusion reaction, with very few compatible red blood cell donors in the world. In this study, we present a case of successful pregnancy managed with autologous blood donations and plasmapheresis.

Pure white cell aplasia an exceptional condition in the immunological conundrum of thymomas: Responses to immunosuppression and literature review.

Thymomas are tumours frequently associated with autoimmune manifestations or immunodeficiencies like Good syndrome. In rare cases, pure white cells aplasia (PWCA) has been described in association with thymomas. PWCA is characterized by agranulocytosis of autoimmune background primary refractory to granulocyte colony-stimulating factor (G-CSF). It is necessary the use of immunosuppressor to allow granulocyte recovery. Without treatment, it could be fatal.
