BACKGROUND: The relationship between health status, defined by frailty and comorbidities, and serum T levels has been widely demonstrated in general population, while only one previous retrospective study has explored it in HIV-infected men1. AIM: To investigate the association between frailty and go- nadal status by assessing serum total T (TT) with Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS) in a cohort of HIV-infected men. METHODS: Prospective, cross-sectional, observational study on HIV-infected men (age <50 years) with on- going Highly Active Antiretroviral Therapy. Serum TT was assessed by the gold standard ID-LC-MS/MS. Sex hormone-binding globulin (SHBG) was measured by chem- iluminescent immunoassay. Calculated free T (cFT) was obtained by Vermeulen equation. Multimorbidity was de- fined as at least 3 comorbid conditions, including: hyperten- sion, diabetes, cardiovascular disease, chronic obstructive pulmonary disease, chronic kidney disease, osteoporosis, chronic viral hepatitis and cancers. Frailty was calculated through the validated 37-item frailty index (FI)2. Patients with FI>0.21 were considered frail. Statistical ana- lysis: Mann-Whitney U test was used to compare contin- uous variables. Correlations were performed using linear regression models. RESULTS: 315 consecutive HIV-infected men were enrolled (mean age 45.3±5.3 years; average duration of HIV-infection 16.3±8.8 years). 128 patients (40.5%) were co- morbid and 207 (64.9%) were frail. Either cFT (p=0.001) or TT (p<0.001) were lower in comorbid patients than others. FT was inversely related to the number of comorbidities (p<0.001, R2=0.045). Accordingly, cFT (p=0.003) and TT (p<0.001) were significantly lower in frail patients.Frailty score was inversely correlated with cFT (p<0.001, R2=0.058), TT (p=0.041, R2=0.014) and SHBG (p=0.003, R2=0.029). However, after adjustment for age and duration of HIV-infection, cFT, TT and SHBG were excluded from the regression model. CONCLUSIONS: Low cFT and TT levels are associated with multimorbidity and poor health status in HIV infected men. The bidirectional nature of this relationship leads to the figuration of an intriguing vicious circle where T de- ficiency triggers the onset of comorbidities or, vice versa, poor health status induces hypogonadism. At the same time, notwithstanding the inverse relation between FT and frailty, it seems that other stronger predictive factors, and in particular the duration of infection, are involved in de- termining the health outcome in this clinical setting.

Abstract

BACKGROUND: The relationship between health status, defined by frailty and comorbidities, and serum T levels has been widely demonstrated in general population, while only one previous retrospective study has explored it in HIV-infected men1. AIM: To investigate the association between frailty and go- nadal status by assessing serum total T (TT) with Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS) in a cohort of HIV-infected men. METHODS: Prospective, cross-sectional, observational study on HIV-infected men (age <50 years) with on- going Highly Active Antiretroviral Therapy. Serum TT was assessed by the gold standard ID-LC-MS/MS. Sex hormone-binding globulin (SHBG) was measured by chem- iluminescent immunoassay. Calculated free T (cFT) was obtained by Vermeulen equation. Multimorbidity was de- fined as at least 3 comorbid conditions, including: hyperten- sion, diabetes, cardiovascular disease, chronic obstructive pulmonary disease, chronic kidney disease, osteoporosis, chronic viral hepatitis and cancers. Frailty was calculated through the validated 37-item frailty index (FI)2. Patients with FI>0.21 were considered frail. Statistical ana- lysis: Mann-Whitney U test was used to compare contin- uous variables. Correlations were performed using linear regression models. RESULTS: 315 consecutive HIV-infected men were enrolled (mean age 45.3±5.3 years; average duration of HIV-infection 16.3±8.8 years). 128 patients (40.5%) were co- morbid and 207 (64.9%) were frail. Either cFT (p=0.001) or TT (p<0.001) were lower in comorbid patients than others. FT was inversely related to the number of comorbidities (p<0.001, R2=0.045).
