Abstract

Background: Functional hypothalamic amenorrhea (FHA) and polycystic ovary syndrome (PCOS) are pathologies most common in women of reproductive age. Menstrual irregularities (oligo/amenorrhea) are the most common symptom of these diseases. FHA develops against the background of stress or excessive physical exertion, and is characterized by inhibition of neuroendocrine regulation of the hypothalamic-pituitary-ovarian axis with a subsequent decrease in the production of sex steroids. For PCOS, the most important pathogenetic links are insulin resistance and hyperandrogenism. The pathology of neuroendocrine regulation in ovarian hyperandrogenism is accompanied by excessive pulsatile secretion of gonadotropin-releasing hormone (GnRH), promoting increased production of luteinizing hormone (LH). Both FHA and PCOS lead to multiple complications from other organs and systems: cardiovascular pathology, decreased bone mineral density with prolonged amenorrhea and contribute to the development of infertility.

Objective: To analyze the works studying the problems of differential diagnosis of FHA and PCOS.

Methods: Using PubMed, eLibrary, CyberLeninka.ru, a systematic search was conducted for articles published over the past 6 years that met the following criteria: the research that describe methods and develop criteria for the differential diagnosis of FHA and PCOS. Selected impactive publications within 1998-2018 were also included in the review.

Results: This review highlights the differential diagnostic criteria for FHA and PCOS. The features of clinical, laboratory and instrumental studies are also described. Publications describing the coexistence of these pathologies in women are analyzed, and methods that allow differentiating these nosologies are described in detail.

Conclusion: A correct and timely diagnosis facilitates the prescription of appropriate treatment regimens, reduces the incidence of complications and improves the quality of life of women. In light of recent advances in the description of the mechanisms of neuroendocrine regulation of the reproductive system, it is necessary to further conduct research to study the role of neuropeptides in the development of FHA and PCOS, which may serve to create more accurate diagnostic markers of diseases.
