Role of Collagen Gene Polymorphisms in the Structure of Early Gestation Loss.

Studies of collagen gene polymorphisms associated with predisposition to early recurrent miscarriages revealed significant differences in the distribution of COL1A1 C-1997A C>A (rs1107946) genotypes and alleles in the group of pregnant patients with early miscarriages in comparison with controls (normal pregnancy). Identification of COL1A1 C-1997A C>A (rs1107946) collagen gene polymorphisms at the stage of pregnancy planning will make it possible to form early miscarriage risk groups for more thorough preparation to gestation and optimization of follow up of this patient population.

[Diagnosis of the causes and prevention of intrauterine fetal death in the second trimester of pregnancy in women with hyperandrogenism]. / Diagnostika prichin i profilaktika vnutriutrobnoi gibeli ploda vo II trimestre beremennosti u zhenshchin s giperandrogeniei.

Differential diagnosis of the causes of intrauterine fetal death was carried out in 84 women; in 57 of them it was due to hyperandrogenism of various origins. 63.2% of patients suffered from mixed (combined ++ovario-adrenal) androgen hypersecretion, 33.3% from the adrenal and only 3.5% of women from the ovarian form of hyperandrogenism. Relationship between the frequency of intrauterine fetal death, the pregnancy term and the form of hyperandrogenism was revealed. Differential diagnosis of hyperandrogenism forms and preparatory pathogenetic therapy helped preserve the pregnancy and resulted in delivery of a viable healthy child in 77.4% of the examined women.
