Polycystic Ovary Syndrome, Mitochondrial Dysfunction, Obesity, Insulin Resistance Infertility (POMODORI) Cohort

Recruiting

• Conditions: Infertility, Female; Polycystic Ovary Syndrome; Mitochondrial Alteration; Obesity; Insulin Resistance; Primary Ovarian Insufficiency

• Registration Number: NCT06167135
• Lead Sponsor: Semmelweis University

Brief Summary

Enrolling of 150 female patients of fertile age diagnosed with PCOS, insulin resistance, infertility, or mitochondrial disease, and the same number of age- and sex-matched controls are planned.

During the research biomarkers already with mitochondrial dysfunction in the scientific literature and common mtDNA abnormalities (deletions, point mutations, copy number changes, etc.) are examined.

Detailed Description

Mitochondrial dysfunction can be involved in the development of clinically heterogeneous diseases affecting multiple tissues and organs and can manifest at any age. Clinical signs are mainly manifested in the most energy-demanding tissues, such as the central nervous system, striated muscles, cardiac musculature, endocrine glands, liver, kidney, and sensory organs.

Polycystic ovarian syndrome (PCOS) is a multifactorial disorder with endocrine dysfunction characterized by ovulatory dysfunction, obesity, insulin resistance (IR), hirsutism, mild persistent inflammation, and ultrasonographically confirmed polycystic ovarian morphology. PCOS affects 5-15% of women of reproductive age. PCOS and IR are also common and treatable causes of infertility. As a result of delaying childbearing until later in life, this problem is affecting more and more couples. In the present study, the investigators hypothesize that PCOS, IR, and infertility associated with these conditions may also be a manifestation of mitochondrial dysfunction, the role of mitochondrial dysfunction in these conditions has been investigated to a limited extent based on the current literature.

Recent literature has shown that mitochondrial dynamics and morphology are two of the major factors in the development of insulin resistance and diabetes mellitus by regulating glucose metabolism. The investigators of this study cohort hypothesize that PCOS and IR may also be a manifestation of a primary mitochondrial pathology, the prevalence of IR and PCOS in primary mitochondrial patients has not yet been investigated based on the current literature. Recent literature suggests that mitochondrial dynamics and morphology are two of the main factors in the development of insulin resistance and diabetes mellitus by regulating glucose metabolism.

In the present experimental design, mitochondrial dynamics, bioenergetics, and autophagy pathways are hypothesized to play a key role in the pathomechanisms of PCOS and IR. A better understanding of the role of mitochondrial pathways in the pathophysiology of PCOS and IR may help to develop new biomarkers or therapeutic targets.

Primary Outcome Measures

Name	Time	Method
Clinical Pregnancy Rate	One year	Clinical pregnancy rate = the number of clinical pregnancies/the total number of participants in the patient cohort × 100%
Serum Glucose and Insulin Levels	One year	The serum glucose and insulin levels are calculated by using plasma concentrations of insulin and glucose obtained during 120 min of a standard (75 g glucose) OGTT. Fasting, 1h and 2h glucose and insulin levels are measured

Secondary Outcome Measures

Name	Time	Method
Baseline Female Sex Hormone Levels and Thyroid Hormone Levels	One year	Measurement of the baseline female sex hormone: anti-Mullerian hormone (AMH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, progesterone, total testosterone, free testosterone, SHBG) and thyroid hormone levels (thyroid stimulating hormone (TSH), T3, T4 + anti-thyroid peroxidase antibody, anti-thyroglobulin antibody) - in the unit of measurement used for the hormone concerned
