Analysis of vitamin D receptor gene polymorphisms in women with and without endometriosis

AbstractAn aberrant immunologic mechanism has been suggested to be involved in the pathogenesis of endometriosis. Genetic alterations in the vitamin D receptor gene (VDR) may lead to important defects in gene activation that principally affect immune function. We have hypothesized a possible relationship between endometriosis and/or infertility and the VDR polymorphisms (ApaI, TaqI, FokI, and BmsI). The study was a case–control study including 132 women with endometriosis-related infertility, 62 women with idiopathic infertility, and 133 controls. VDR polymorphisms were studied by restriction fragment length polymorphism. We found relatively similar VDR polymorphism genotype frequencies in cases and controls. When patients with minimal/mild and moderate/severe endometriosis were studied separately, no difference was found. When we compared infertile groups with and without endometriosis there was no statistically significant difference. The data suggest that VDR polymorphisms did not play an important role in the pathogenesis of endometriosis and/or infertility in the Brazilian women studied

Warfarin: pharmacological profile and drug interactions with antidepressants

Oral anticoagulants are among the drugs with the greatest numberof drug interactions. The concomitant use of several medications isa common practice in patients with cardiovascular problems, whooften also present with depression; therefore, the probability of aninteraction occurring between warfarin and the antidepressants ishigh, and may result in increased or decreased anticoagulant activity.Since the possible interactions between these two classes of drugshave been poorly explored in literature, with a risk to the patients who use them, we reviewed the pharmacology of warfarin and its possible interactions with antidepressants. Of the antidepressants analyzed, those that showed relevant effects on the interaction with warfarin were, in decreasing order: paroxetine, venlafaxine, fluoxetine, and duloxetine
