Determinants of sexual function in men living with HIV younger than 50 years old: Focus on organic, relational, and psychological issues.

BACKGROUND: Sexual dysfunctions, particularly erectile dysfunction, are common in men living with HIV, whose organic and psychological components remain to be clarified. The aim of the study is to investigate the impact of risk factors of sexual dysfunctions, including organic, relational, and psychological determinants of erectile function, in men living with HIV younger than 50 years old. METHODS: A cross-sectional, observational study was conducted in men living with HIV < 50 years. The questionnaire International Index of Erectile Function-15 was used to assess the prevalence and degree of erectile dysfunction. The structured interview of erectile dysfunction was used to explore the organic (Scale 1), relational (Scale 2), and psychological (Scale 3) components of erectile dysfunction. Total testosterone, estradiol, and dihydrotestosterone were measured by liquid chromatography-tandem-mass spectrometry; free testosterone was calculated by the Vermeulen equation. RESULTS: A total of 313 consecutive men living with HIV were prospectively enrolled (median age 47.0 years; median HIV-infection duration 16.2 years). 187 patients (59.7%) had erectile dysfunction, with a higher prevalence of non-heterosexual (138 out of 187, 73.8%) than heterosexual patients (p = 0.003). Patients with erectile dysfunction showed a worse score of structured interview of erectile dysfunction scale 3 compared to patients without erectile dysfunction (p = 0.025); the International Index of Erectile Function-15 was inversely related to structured interview of erectile dysfunction scale 3 (p = 0.042). No difference was found for sex steroids (total testosterone, estradiol, free testosterone, and dihydrotestosterone) between men living with HIV with and without erectile dysfunction. In the multivariate analysis sexual orientation, and lack of stable relationships were major determinants for erectile dysfunction. Only 35 of 187 patients with erectile dysfunction (18.7%) reported the use of erectile dysfunction medications. CONCLUSIONS: Within the multidimensional network of erectile dysfunction in men living with HIV, the psychological component is predominant, highlighting the contribution of peculiar factors related to HIV distress (e.g., fear of virus transmission, stigma) rather than gonadal status and other classical risk factors. In contrast to the high prevalence, only a few patients reported the use of erectile dysfunction medications suggesting a general under-management of such issues.

Primary, secondary and compensated male biochemical hypogonadism in people living with HIV (PLWH): relevance of sex hormone-binding globulin (SHBG) measurement and comparison between liquid chromatography-tandem mass spectrometry (LC-MS/MS) and chemiluminescent immunoassay for sex steroids assay.

BACKGROUND: Data about classification of hypogonadism and estrogen deficiency in male people living with HIV (PLWH) are scanty. AIM: To investigate the prevalence and characterization of biochemical hypogonadism and relative estrogen deficiency in male PLWH aged < 50 comparing liquid chromatography-tandem mass spectrometry (LC-MS/MS) with chemiluminescent immunoassay (CI), and combining gonadotropin, sex hormone-binding globulin (SHBG) and serum estradiol (E2) measurements. METHODS: Prospective, cross-sectional, observational study. Serum total testosterone (TT), E2, gonadotropins, SHBG were measured by CI. TT and E2 were also assessed by LC-MS/MS. Free testosterone (cFT) was calculated by Vermeulen equation. RESULTS: A total of 316 PLWH (45.3 ± 5.3 years) were enrolled. TT and cFT by LC-MS/MS were lower compared to CI (p < 0.0001). The prevalence of biochemical hypogonadism was higher with LC-MS/MS than CI, both for TT (5.1% vs 3.2%, p < 0.0001) or cFT (9.5% vs 7%, p < 0.0001). The prevalence of hypogonadism (overt + compensated) was 17.1% for cFT using LC-MS/MS. Secondary form of hypogonadism was more prevalent than primary. The prevalence of relative estrogen deficiency was of 30.0% among hypogonadal patients and 15.5% among eugonadal. CONCLUSIONS: The prevalence of male hypogonadism results underestimated by CI compared to LC-MS/MS in PLWH, both for TT and cFT. SHBG and gonadotropins are essential for detecting T deficiency.

HIV and Sexual Dysfunction in Men.

Sexual issues tend to go unaddressed in human immunodeficiency virus (HIV) management, although overt sexual dysfunctions are more prevalent in people living with HIV than uninfected people. Erectile dysfunction is the most frequent sexual problem, with a prevalence of 30-50% even in men <40 years of age, but other issues such as loss of libido and ejaculatory disorders should not be overlooked. Peculiar factors related to HIV infection (e.g., fear of virus transmission, changes in body image, HIV-related comorbidities, HIV distress and stigma), alongside classical factors non-related to HIV, should be considered when approaching sexual problems in HIV patients. For this reason, the diagnostic and therapeutic workout of sexual dysfunction in the context of HIV requires a multidisciplinary approach, involving specialists in both infectious diseases and sexual medicine. This narrative review presents an overview of current knowledge on sexual dysfunction in HIV men, deepening the factors driving and taking part in these issues, providing advice for the clinical approach, and underlining the importance of caring for sexual health to improve the quality of life of HIV patients.

Health status is related to testosterone, estrone and body fat: moving to functional hypogonadism in adult men with HIV.

OBJECTIVE: Hypogonadism is common in HIV-infected men. The relationship between health status, sex steroids and body composition is poorly known in HIV. The aim was to investigate the association between health status (comorbidities/frailty), body composition, and gonadal function in young-to-middle-aged HIV-infected men. DESIGN: Prospective, cross-sectional, observational study. METHODS: HIV-infected men aged <50 years and ongoing Highly Active Antiretroviral Therapy were enrolled. Serum total testosterone (TT), estradiol (E2), estrone (E1) were measured by liquid chromatography-tandem mass spectrometry, LH and FSH by immunoassay. Free testosterone (cFT) was calculated by Vermeulen equation. Body composition was assessed by dual-energy X-ray absorptiometry and abdominal CT scan. Multimorbidity (MM) and frailty were defined as ≥3 comorbidities and by a 37-item index, respectively. RESULTS: A total of 316 HIV-infected men aged 45.3 ± 5.3 years were enrolled. Body fat parameters were inversely related to cFT and TT, and directly related to E1 and E2/testosterone (TS) ratio. Patients with MM had lower cFT (P < 0.0001) and TT (P = 0.036), and higher E1 (P < 0.0001) and E2/TS ratio (P = 0.002). Frailty was inversely related to cFT (R2 = 0.057, P < 0.0001) and TT (R2 = 0.013, P = 0.043), and directly related to E1 (R2 = 0.171, P < 0.0001), E2 (R2 = 0.041, P = 0.004) and E2/TS ratio (R2 = 0.104, P < 0.0001). CONCLUSIONS: Lower TT and cFT, higher E1, E2/TS ratio and visceral fat were independently associated to poor health status and frailty, being possible hallmarks of unhealthy conditions in adult HIV-infected men. Overall, MM, frailty and body fat mass are strictly associated to each other and to sex steroids, concurring together to functional male hypogonadism in HIV.
