The incidence and aggravating factors of male hypogonadism in type 2 diabetes

BACKGROUND: Male hypogonadism is associated with type 2 diabetes mellitus (T2DM), therefore, it is of interest to study its frequency. The clinical symptoms of hypogonadism are not specific, and laboratory diagnostics is the basis for its detection. The optimal method for this diagnostics is isotope dilution liquid chromatography/tandem mass spectrometry, which was used in our study.

 AIMS: Assessment of the incidence and aggravating factors of male hypogonadism in type 2 diabetes

MATERIALS AND METHODS: A full-design, cross-sectional, screening, single-center, non-interventional study included men with T2DM, who were he was treated in Endocrinology Research Centre, Moscow. The study was conducted from October 2021 to January 2022. Medical history assessment, physical examination with determination of body mass index (BMI), measurement estimation of total testosterone by isotope dilution liquid chromatography/tandem mass spectrometry, glycated hemoglobin (HbA1c) and lipid profiles were performed. The groups were compared using the Mann-Whitney U-test for quantitative indicators and χ² with Yates’ correction for qualitative ones. Differences were considered statistically significant with p0,05.

RESULTS: Hypogonadism was detected in 355 (70.3%) men with T2DM. Patients with hypogonadism had statistically significantly higher BMI, worse glycemic control, lower HDL levels, and higher triglycerides than eugonadal men. An additional comparative analysis among non-obese individuals showed the presence of statistically significant differences in the level of HbA1c (higher in hypogonadal men) and HDL (lower in hypogonadal men). An analysis of hypogonadal patients depending on the presence of obesity showed statistically significant differences between groups in the level of total testosterone (lower in obese men) and triglycerides (higher in obese men).

CONCLUSIONS: The prevalence of male hypogonadism in type 2 diabetes was 70,3%. Its development was associated with obesity and poor glycemic control.

Androgen Deficiency In Men With Chronic Obstructive Pulmonary Disease

Hypogonadism is a clinical condition comprising symptoms and laboratory evidence of testosterone deficiency and low androgen receptor sensitivity. The importance of hypogonadism in clinical practice is often underestimated. Androgen deficiency habitually occurs in various conditions causing abnormal functioning of many organs and systems, as well as impairing the quality of life in patients. Androgen deficiency often occurs with various somatic diseases. Chronic obstructive pulmonary disease (COPD) is one of the most important medical and social problems of modern medicine, in which severe systemic (including hormonal) disorders occur. This review presents data on androgen deficiency in men with COPD and its potential impact on the patients. We have analyzed literary sources in the eLIBRARY and PubMed databases.

[Current understanding of the role of age-related hypogonadism in the development of cardiovascular diseases]

The literature review presents novel data on the prevalence of age-related hypogonadism and its relationship with aging, its impact on the circulatory system and cardiovascular diseases. This review summarizes the methods for diagnosing age-related hypogonadism, its association with traditional cardiovascular risk factors such as dyslipidemia, insulin resistance and diabetes mellitus, obesity, arterial hypertension. The mechanisms of the possible direct effect of testosterone on endothelium and vascular tone, the role of hormone replacement therapy as a way of preventing cardiovascular diseases are discussed.

[Androgens and Antiandrogens influence on COVID-19 disease in men]

The WHO has declared a SARS-CoV-2 pandemic. During a pandemic, the researches aimed at finding the new treatments for SARS-CoV-2 become relevant. The review focuses on studies of androgens and antiandrogens in this disease. Since the beginning of the COVID-19 epidemic, it has been noted that men have more severe forms of infection and higher mortality. The main cause of both the severity of the disease and the high mortality of men from COVID-19 are associated with androgens. It was found that patients receiving androgen deprivation are less likely to become infected and easily tolerate COVID-19. The researchers explain the effect of the therapy by the effect on the TMPRSS2 protein. It was found that both TMPRSS2 expression and a more severe course of coronavirus infection are observed in men with hyperandrogenism - androgenic alopecia, acne, excessive facial hair growth and increased skin oiliness. In this regard, some researchers suggest to use androgen deprivation for men at high risk of developing COVID-19. Steroid and non-steroidal antiandrogens are used for androgen deprivation. At the same time, obtaned scientific data on the relationship of severe forms and mortality of COVID-19 with low testosterone levels leads to a hypothesis about the possibility of a positive effect not of androgen devrivation therapy but of androgen replacement therapy in case of hypogonadism have diagnosed. These studies have not been completed recently, and data on the effectiveness and safety of antiandrogens and androgens in the treatment of a new coronavirus infection require clarification.
