ABSTRACT

Allogeneic bone marrow transplantation (BMT) is an effective treatment for some severe hematologic or nonhematologic diseases. The blood group antigen mismatch between donor and recipient may cause immunohematological complications during or after BMT. In this review, we analyze the ABO, Rh and other red cell antigen mismatches between donor and recipient, the main immunohematological complications and the techniques to prevent them. The data reported are derived from the experience of the authors and from the medical literature. The clinical implications of the immunohematological aspects of BMT emphasize the importance of close immunohematological monitoring in patients undergoing allogeneic BMT with ABO, Rh or other red cell antigen mismatches between donor and recipient.

ABSTRACT

BACKGROUND: HIV-infected patients may contract a variety of other concurrent infections, including Mycoplasma pneumoniae, cytomegalovirus (CMV) and Epstein-Barr virus (EBV), that are known to be causes of transient cold agglutinins (CA). The aim of this study was to search for the prevalence, the persistence and the significance of CA in HIV antibody-positive patients. METHODS: Ninety patients belonging to different risk groups (drug addicts, homosexuals and hemophiliacs), including 15 with AIDS, 20 with ARC, 25 with PGL, 30 symptom-free individuals and 100 healthy blood donors were assessed for the presence of CA for at least six months. RESULTS: In 20 cases (22%) CA were found: 3, 7, 5 and 5 respectively, in each of the above mentioned HIV-positive groups, while the group used as control was CA-negative. There were no differences between CA-negative and CA-positive patients with regard to the presence of anemia, frequency of other infections, or development of lymphatic malignancy during the follow-up period. Serological specificity of CA included 14 of type anti-I, 5 of anti-i and 1 of anti-Pr specificity. CONCLUSIONS: It appears that CA production is another immune disorder of patients with HIV infection.

ABSTRACT

A case of erythrocytic polyagglutination in a healthy blood donor is reported. After a review of current literature, the results of clinical and serologic tests which led to the diagnosis of Tn-red cells polyagglutination are presented. This is only the sixth case of Tn-activation in a healthy blood donor. The clinical and forensic significance of this rare phenomenon is discussed.
