The Significance of Imunohematology Research in Relation to Menagement of Hemolitical Diseases of the Newborn in Republic of Macedonia

Abstract

AIM: Prompt discovery of allosensibilisation to RBC’s antigens during pregnancy and successful management of HDFN in Republic of Macedonia, in order to decrease morbidity and mortality of the fetus and the newborn.MATERIALS AND METHODS: The study comprises in total 23,800 patients, 14,858 pregnant women and 8,842 newborn babies.RESULTS: The screening and identification of anti RBC’s antibodies detected in total 216 alloantibodies, out of which 81% (175) had a clinical significance. Out of the above mentioned 164 alloantibodies (65.9%) belong to the Rh system. The most often reason for a severe hemolytic disease is the anti-D antibody. The HDFN symptoms of mild and moderate degree demonstrated 32.5%, and 18.9% had symptoms of severe fetal suffering, and almost half of them (48%) were with or with mild HDFN and had no need of therapy. In 15% it was about alloantibodies of other Rg antigens: anti-C, anti-E and anti-c, at which in most cases there were no signs of HDFN, or it showed weak symptoms (89%), just one case of anti-c ended with intrauterine death.CONCLUSIONS: Anti D antibody represents the most often reason for severe HDFN and displays a need of intrauterine transfusion and exsangvino transfusion. Anti-c is the only antibody that demonstrated the same potential for severe HBN as the anti-D. The most often reason for alloimmunisation of the mother is the lack of RhIG prophylaxis (97.8): postnatal, antenatal and in case of possible sensible conditions during pregnancy. Thus, there is a need and an outmost importance of elaboration and adoption of the National programe for RhIG prophylaxis in Republic of Macedonia.
