Habituel Abortusların Prognozunda Kantitatif Hormon Tayinleri

Abstract

Objective To assess how quantitative measurements of placental hormones and metabolites predict pregnancy outcomes in women with habitual abortion. Methods Literature was reviewed on hCG, HPL, progesterone (urinary pregnanediol), estriol, and thyroid markers in early pregnancy. Key studies correlating these hormone levels with miscarriage risk were analyzed. Results Early gestational hCG levels below reference ranges predict poor implantation and miscarriage. HPL—measurable by day 35—provided 76% predictive accuracy for threatened abortion outcomes when combined with hCG. Low urinary pregnanediol (<5 mg/day) indicates luteal insufficiency and is associated with miscarriage, though some low-level pregnancies progress. Estriol excretion under 1 mg/day correlates with adverse outcomes and small-for-gestational-age fetuses; normal rises typically exceed 10 mg/day by first trimester end. Thyroid binding globulin (PBI) increases in normal pregnancies; absent rise signals heightened miscarriage risk. Adrenal 17-ketosteroid excess may also contribute. Conclusion Serial quantitative assays of hCG, HPL, pregnanediol, and estriol in early pregnancy provide valuable prognostic information in women with recurrent miscarriage, guiding potential interventions.
