Abstract

Background: Chronic anemia in SCD during pregnancy could lead to a cascade of maternal and fetal complications. The aim of this study is to assess the various types of ABO blood groups of pregnant SCD women at booking and the severity of anemia. The outcome of this study will help in making recommendations of ABO blood types most suitable to improve the quality of life of SCD patients. This may contribute to guideline for safe blood transfusion in SCD. Methodology: This was a-ten-year retrospective study of all registered SCD pregnant women seen at the antenatal clinic of Braithwaite Memorial Specialist Hospital (BMSH) Port Harcourt (January 2004-December 2013). Data on gestational age, Hemoglobin (HB) electrophoretic pattern, HB concentration and blood group were obtained at booking clinic. Data were analysed using Epi-info version 7.02 by WHO, Geneva Switzerland and CDC, USA. Result: A total of 52 Hb SS pregnant women were seen during the study period. The average booking trimester was the 2 nd trimester. 94.2 % (49) were anemic (<11.0 g/ dl) while 5.8% (3) were non anemic (≥11 g/dl). 27.0%, 9.6% and 61.5% were A, B and O rhesus D positive blood groups respectively. No AB blood group was recorded from this study. The O rhesus D positive blood group was significantly more prone to anemia [30 (61.2%)] than other ABO blood groups (X 2 =50.37; 0.001). 20% (1/5) of B rhesus D positive and 6.3% (2/32) of O rhesus D positive patients were non-anemic. All A rhesus D positive blood were anemic. The highest prevalence of A rhesus D positive blood group (37.5%) was in 2 nd trimester, that of B (20%) and O (66.7%) rhesus D positive blood groups were in 1 st and 3 rd trimesters respectively. Conclusion: Although most SCD pregnant women in this region are O rhesus D positive blood groups, B rhesus D positive blood group patients appear to be less susceptible to anemia. There is need to carry out more elaborate study on this blood group.
