Local immunity in pregnant women.

Immunoglobulins IgA and IgG levels and Lysozyme-activity were examined in the vaginal fluid of 70 pregnant women and 30 non-pregnant women where microbiological examinations did not detect any pathological microorganisms. To confirm the local character of immune factors produced in the female genital tract, these factors were also examined in the sera. An increase of class A immunoglobulins was noted in the vaginal fluid and examined sera. IgA/IgG ratio as well as statistical calculations confirmed the local origin of antibodies within the classes. The lysozyme activity was 10 times greater in the vaginal fluid than in the sera. Both factors are relatively simple to determine and in women with recurrent inflammatory conditions of the vaginal tract can be used as indicators of the local immunity state.

Angiotensin II type 1 receptor gene A1166C polymorphism is associated with the increased risk of pregnancy-induced hypertension.

OBJECTIVE: The aim of our study was to evaluate the relation of parental history of hypertension to the development of PIH, and to assess the potential role of plausible candidate loci in the susceptibility to PIH. STUDY DESIGN: Five polymorphisms: ACE gene I/D and Pst1 RFLP polymorphism, AGT gene M235T polymorphism, AGTR1 gene A1166C polymorphism, and chymase gene CMA/B polymorphism were studied in 126 women suffering from PIH in comparison with 150 healthy pregnant women. Genotyping was performed using methods based on polymerase chain reaction. RESULTS: Among the PIH patients, positive parental history of hypertension (hypertension in both parents, in mother alone or in father alone) was significantly more frequent than in healthy pregnant women. Having a hypertensive father or mother statistically significantly increased the risk of PIH (odds ratio 4.34, 95% CI, 1.86-10.13, and 2.33, 95% CI, 1.29-4.12 respectively). CC genotype was significantly more frequent in women with PIH as compared with healthy controls and the C allele frequency was also significantly higher among the cases compared to controls. Having a CC genotype increased the risk of development of PIH 2.74 times (95% CI, 1.08-6.97). We observed no significant differences in genotype distributions or the allele frequencies of other examined polymorphisms. CONCLUSION: On the basis of the results of our study, we may suggest that AGTR1 gene A1166C polymorphism may predispose women to the development of PIH. It seems that ACE gene I/D and Pst1 RFLP polymorphism, AGT gene M235T polymorphism, and finally chymase gene CMA/B polymorphism do not play any significant role in the pathogenesis of PIH in Caucasian women.
