The PROGINS progesterone receptor gene polymorphism and idiopathic recurrent miscarriage.

OBJECTIVE: Progesterone inhibits lymphocyte cytotoxicity, natural killer cell degranulation, and release of proinflammatory cytokines and has been shown to protect against spontaneous miscarriage. We investigated the association between idiopathic recurrent miscarriage (IRM) and the PROGINS 306 base pair insertion polymorphism in intron G of the progesterone receptor gene, which is known to segregate with progesterone-dependent neoplasms. METHODS: In a case-control study we investigated 125 women with a history of three or more consecutive pregnancy losses before 20 weeks' gestation and 79 healthy controls with at least two live births and no history of pregnancy loss. Peripheral venous puncture, DNA extraction, and polymerase chain reaction were used to genotype women for the presence of the PROGINS polymorphism. RESULTS: Allele frequencies among women with IRM and controls were 85.2% and 89.2%, respectively, for allele T1 (wild type) and 14.8% and 10.8%, respectively, for allele T2 (mutant). No association between allele T2 and the occurrence of IRM was found (P =.3; odds ratio [OR] 0.69; confidence interval [CI] 0.34, 1.40). Genotype frequencies were not significantly different between the study group (T1/T1 73.6%, T1/T2 23.2%, T2/T2 3.2%) and the control group (T1/T1 79.7%, T1/T2 19%, T2/T2 1.3%) (P =.4). Between women with primary and secondary IRM, there were no statistically significant differences with respect to allele frequencies (82% versus 87%, P =.4 for allele T1 and 12% versus 13%, P =.6 for allele T2). CONCLUSIONS: We found that the PROGINS polymorphism in the progesterone receptor gene was not associated with IRM in white women.

Maternal basic fibroblast growth factor serum levels are associated with pregnancy-induced hypertension.

OBJECTIVE: To test the hypothesis that serum levels of basic fibroblast growth factor (bFGF) are altered among women with pregnancy-induced hypertension (PIH) and are associated with disease severity. METHODS: We evaluated serum levels of bFGF in 46 women with PIH, 46 age- and parity-matched healthy pregnant women, and 46 healthy nonpregnant controls. Enzyme-linked immunosorbent assays were used to determine serum levels of bFGF. Results were correlated to clinical data. RESULTS: The overall mean serum levels of bFGF were 3.2 (standard deviation [SD] 9.3) micromol/L. Mean serum levels of bFGF in normal controls, healthy pregnant women, and women with PIH were 0 (SD 0) micromol/L, 2.6 (SD 6.3) micromol/L, and 6.8 (SD 13.8) micromol/L, respectively (P =.003) for normal controls compared with healthy pregnant women and P <.001 for healthy pregnant women compared with women with PIH). In a univariate logistic regression model bFGF showed a significant influence on the odds of presenting with PIH compared with healthy pregnant women (P =.002). The mean serum levels of bFGF in women with severe PIH and in women with mild PIH were 4.4 (SD 10.6) micromol/L and 9.5 (SD 17.3) micromol/L, respectively (P =.1). In a univariate logistic regression model bFGF did not reveal a significant influence on the odds of developing severe PIH (P =.3). CONCLUSIONS: Elevated serum levels of bFGF are associated with PIH, but bFGF does not seem to be a useful prognostic parameter for severe PIH.
