title: Comparison of pregnancy outcomes in women with sickle cell disease and trait.
abstract: OBJECTIVE
  To compare the pregnancy and neonatal outcome in sickle cell disease and trait women.
  
  
  METHODS
  The retrospective comparative study was conducted at Abha General Hospital, Abha, Saudi Arabia, from January 2009 to December 2011. The records of women having sickle cell disease and trait were reviewed for antenatal and postnatal complications. Pregnancy and foetal outcome was also compared in both the groups. Chi-square, Fisher's Exact and Student's t tests were used for statistical analysis.
  
  
  RESULTS
  Out of 112 women, 57 (50.89%) had sickle cell disease and 55 (40.10%) had sickle cell trait. The mean gravidity and parity in the latter group (5.05+/-3.51 and 3.2+/-2.74 respectively) was more than double in the former group (2.89+/-1.36 and 1.66+/-0.96 respectively). There were significant differences in antenatal complications. In the disease group, anaemia was in 55 (96.5%) cases compared to 35 (63.6%) in the trait group. Significant number of women in the first group (n=41; 71.9%) experienced painful crisis in pregnancy compared to 4 (7.27%) in the second group. Mean haemoglobin in the disease group was 8.35g/dl, while it was 9.96 g/dl in the other (p <0.01). The requirement of blood transfusion was higher in the former, 28 (38.6%) than in the latter 3 (5.54%). Frequency of preterm delivery was only slightly higher in the disease group, 14 (28.57%) than in the trait women, 13(23.63%). The mean birth weight of babies of women with the disease and the trait was 2380 and 2480 grams. This 100 grams difference, however, was statistically insignificant.
  
  
  CONCLUSIONS
  Patients with sickle cell disease had more antenatal complications than those with sickle cell trait, without affecting the foetal outcome. Though the trait is generally considered a benign disease, women need special care and attention during a stressful situation like pregnancy.
