![]() 10 Serum IgA was shown to have no change, 1,3,5,9 decreased 4,8 or increased. 4–9 The fall in serum IgG levels may be attributed to the haemodilution during pregnancy and transplacental transfer of maternal IgG to the fetus. Reports show that the levels of IgG did not change 1–3 or decreased significantly. Studies on serum immunoglobulin levels are limited in number and showed conflicting findings. Pregnancy is associated with several physiological, hormonal and immunological changes. Serum serial number not showing up serial#This finding would be of greater weight if reproduced in a larger number of subjects with multiple serial samples at fixed regular time intervals during pregnancy and postpartum. In this cross-sectional study, serum total IgE levels showed no statistically significant changes during pregnancy or postpartum. Using analysis of variance, none of these three groups showed significant change in serum total IgE level during pregnancy or postpartum. A history of allergy was positive in 98 samples, negative in 61 and unclear in 59. Serum IgE in the postpartum period also did not differ according to method of delivery. However this was not statistically significant. Postpartum serum IgE level showed a lower mean, 14.9 IU/ml during the early postpartum period (less than 30 days) compared to 30.3 IU/ml during the late postpartum period (30 days-25 weeks). The geometric mean serum total IgE was 20.5 IU/ml in the first trimester, 20.8 IU/ml in the second and 22.2 IU/ml in the third. Analysis was also done according to history of allergy. In addition, the postpartum IgE data were analysed according to the method of delivery. Serum total IgE geometric means were compared at various trimesters and postpartum. Methodsġ59 pregnant subjects provided 218 serum samples during various stages of pregnancy and the postpartum period. To investigate the course of serum total IgE levels during pregnancy and postpartum. Studies on serum IgE levels during pregnancy are limited.
