Abstract

Tobacco smoking products have a heavy impact on the public health of developed as well as non-developed countries by being a main etiologic factor for the induction of cardiovascular diseases and tobacco-related cancer. The purpose of this study was to determine the influence of tobacco smoking on the measurement of the humoral immune response in Egyptian pregnant women with type 1 diabetes. Concentrations of serum immunoglobulin A, G and M in 35 smoking, 35 non-smoking pregnant women with type 1 diabetes and 35 matched normal women were measured by ELISA. Women were matched by age and working life with controls. Measurements suggested that diabetic smokers had decreased levels of IgG and IgM in their sera. It was found that normal individuals had mean IgA, IgG and IgM levels of 2.80 mg/ml, 9.33 mg/ml and 1.66 mg/ml, respectively while non-smoker women suffering from type 1 diabetes had mean levels of 3.47 mg/ml, 10.97 mg/ml and 2.05 mg/ml (p<0.0004,p<0.0001 andp<0.0002). However, the mean level of IgA, IgG and IgM in diabetic smoker sera was determined to be 3.33 mg/ml, 8.07 mg/ml and 1.31 mg/ml, respectively (p<0.003,p<0.0001 andp<0.0001). The obtained results suggest that toxic smoke components were immuno-suppressant and may well play a part in the complex immuno-pathogenesis interaction. The increased risk of smoking in insulin dependent diabetic pregnant women during pregnancy is a further reason to encourage pregnant women to quit tobacco smoking.
