RESUMEN

BACKGROUND AND AIM: Notwithstanding the improvement in therapies, patients affected by thalassemia major (TM) and intermedia (TI) are still at high risk of cardiac complications. This study aimed at evaluating the incidence and predictive factors for developing cardiac events in adult ß-TM and TI patients. POPULATION AND METHODS: Data on diagnosis and clinical history were collected retrospectively; prospective data on new-onset cardiac failure and arrhythmias, echocardiographic parameters, biochemical variables including non-transferrin-bound iron (NTBI) and labile plasma iron (LPI), magnetic resonance imaging (MRI) T2* measurement of hepatic and cardiac iron deposits, and iron chelation therapy were recorded during a 6-year follow-up. RESULTS: Thirty-seven patients, 29 TM and 8 TI, were included. At baseline, 8 TM patients and 1 TI patient had previously experienced a cardiac event (mainly heart failure). All patients were on chelation therapy and only 3 TM patients had mild-to-severe cardiac siderosis. During follow-up, 11 patients (29.7%) experienced a new cardiac event. The occurrence of cardiac events was correlated to high LPI levels (OR 12.0, 95% CI 1.56-92.3, p .017), low mean pre-transfusion haemoglobin (OR 0.21, 95% C.I. 0.051-0.761, p .21) and echocardiographic parameters suggestive of myocardial hypertrophy. Multivariate analysis disclosed high LPI and left ventricle mass index (LVMI) as independent variables significantly associated with cardiac events. Cardiac iron deposits measured by MRI T2* failed to predict cardiac events. CONCLUSION: LPI, Hb levels and echocardiographic parameters assessing cardiac remodelling are associated with cardiac events in adult TM and TI patients. LPI might represent both a prognostic marker and a potential target for novel treatment strategies. Further studies are warranted to confirm our findings on larger populations.

RESUMEN

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.

RESUMEN

Follicle-stimulating hormone (FSH) supports spermatogenesis acting via its receptor (FSHR), which activates trophic effects in gonadal Sertoli cells. These pathways are targeted by hormonal drugs used for clinical treatment of infertile men, mainly belonging to sub-groups defined as hypogonadotropic hypogonadism or idiopathic infertility. While, in the first case, fertility may be efficiently restored by specific treatments, such as pulsatile gonadotropin releasing hormone (GnRH) or choriogonadotropin (hCG) alone or in combination with FSH, less is known about the efficacy of FSH in supporting the treatment of male idiopathic infertility. This review focuses on the role of FSH in the clinical approach to male reproduction, addressing the state-of-the-art from the little data available and discussing the pharmacological evidence. New compounds, such as allosteric ligands, dually active, chimeric gonadotropins and immunoglobulins, may represent interesting avenues for future personalized, pharmacological approaches to male infertility.

RESUMEN

OBJECTIVE: To determine whether characteristics and outcomes of Italian patients in the observational global Hypopituitary Control and Complication Study (HypoCCS) differed according to the degree of GH deficiency (GHD). DESIGN: Patients were grouped by tertiles of stimulated GH peak concentration at baseline (Group A lowest tertile, n = 342; Group B middle tertile, n = 345; Group C highest tertile, n = 338). RESULTS: Baseline demographics, lipid levels, body mass index categories and mean Framingham cardiovascular risk indexes were similar in the three groups and remained substantially unchanged over time, with no subsequent significant between-group differences (except mean levels of triglycerides increased in the highest tertile group). GHD was adult-onset for >75% of patients in all groups. The percentage of patients with multiple pituitary deficiencies was higher in Group A than in the other groups; isolated GHD was reported with highest frequency in Group C. Patients in Group A received the lowest mean starting dose of GH. Hyperlipidaemia at baseline was reported in 35·1%, 31·1% and 24·7% of patients in groups A, B and C, respectively (P = 0·029). Mean duration of GH treatment was 7·21, 5·45 and 4·96 years, respectively. The proportion of patients with adverse events did not differ significantly between groups, with a low prevalence over time of diabetes and cancer. CONCLUSIONS: In Italian patients from HypoCCS, the level of GH deficit did not influence changes over time in metabolic parameters or adverse event profile, despite differences in GHD severity at baseline and in the starting GH dose.

RESUMEN

INTRODUCTION: The prevalence of erectile dysfunction (ED) and its correlates in men with acromegaly has never been investigated. AIM: The aim of this study was to evaluate sexual function in men with acromegaly. METHODS: Multicenter-based, retrospective analysis of a nonselected series of 57 acromegalic subjects (mean age: 52.7 ± 14.2 years) was performed. Acromegalic subjects reporting ED (n = 24) were compared with matched ED patients without acromegaly or pituitary disease (controls), selected from a cohort of more than 4,000 subjects enrolled in the Florence Sexual Medicine and Andrology Unit. MAIN OUTCOME MEASURES: Patients were interviewed using Structured Interview on Erectile Dysfunction (SIEDY) structured interview, a 13-item tool for the assessment of ED-related morbidities. Several clinical and biochemical parameters were taken. Penile color Doppler ultrasound (PCDU) was performed in a subgroup of 37 acromegalic subjects. RESULTS: ED was reported by 42.1% of acromegalic subjects. After adjusting for age and testosterone, acromegalic subjects with ED had a higher prevalence of hypertension and more often reported an impairment of sleep-related erections and a longer smoking habit. Accordingly, acromegaly-associated ED was characterized by a higher organic component and worse PCDU parameters. No relationship between ED and testosterone levels or other acromegaly-related parameters was found. However, acromegalic subjects with severe ED reported a longer disease duration. In a case-control analysis, comparing acromegalic subjects with ED-matched controls free from acromegaly (1:5 ratio), acromegalic men had a worse ED problem and a higher organic component of ED, as derived from SIEDY score. In line with these data, acromegalic patients with ED had a higher prevalence of major adverse cardiovascular events history at enrollment and lower PCDU parameters. CONCLUSIONS: Subjects with complicated acromegaly are at an increased risk of developing ED, especially those with cardiovascular morbidities. Our data suggest including a sexual function evaluation in routine acromegaly follow-up.

RESUMEN

INTRODUCTION: The role of testosterone supplementation (TS) as a treatment for male sexual dysfunction remains questionable. AIM: The aim of this study was to attempt a meta-analysis on the effect of TS on male sexual function and its synergism with the use of phosphodiesterase type 5 inhibitor (PDE5i). METHODS: An extensive Medline, Embase, and Cochrane search was performed. MAIN OUTCOME MEASURES: All randomized controlled trials (RCTs) comparing the effect of TS vs. placebo or the effect of TS as add on to PDE5is on sexual function were included. Data extraction was performed independently by two of the authors (A. M. Isidori and G. Corona), and conflicts resolved by the third investigator (M. Maggi). RESULTS: Out of 1,702 retrieved articles, 41 were included in the study. In particular, 29 compared TS vs. placebo, whereas 12 trials evaluated the effect of TS as add on to PDE5is. TS is able to significantly ameliorate erectile function and to improve other aspects of male sexual response in hypogonadal patients. However, the presence of possible publication bias was detected. After applying "trim and fill" method, the positive effect of TS on erectile function and libido components retained significance only in RCTs partially or completely supported by pharmaceutical companies (confidence interval [0.04-0.53] and [0.12; 0.52], respectively). In addition, we also report that TS could be associated with an improvement in PDE5i outcome. These results were not confirmed in placebo-controlled studies. The majority of studies, however, included mixed eugonadal/hypogonadal subjects, thus imparting uncertainty to the statistical analyses. CONCLUSIONS: TS plays positive effects on male sexual function in hypogonadal subjects. The role of TS is uncertain in men who are not clearly hypogonadal. The apparent difference between industry-supported and independent studies could depend on trial design more than on publication bias. New RCTs exploring the effect of TS in selected cases of PDE5i failure that persistently retain low testosterone levels are advisable.

RESUMEN

Tirzepatide (TZP) is a new anti-obesity drug, and little is currently known about its effect on body composition (BC) in people with overweight or obesity. The aim of this study is to conduct a systematic review on the impact of TZP on BC compartments in this population during weight loss programs. Literature searches, study selection, method development, and quality appraisal were performed. The data were synthesized using a narrative approach, in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Of the 1379 papers retrieved, 6 randomized controlled trials met the inclusion criteria and were reviewed, revealing the following findings. Firstly, TZP was shown to result in a significant reduction in total fat mass (FM), visceral adipose tissue (VAT) and waist circumference (WC) between baseline and short as well as intermediate follow-ups. Compared to other anti-obesity medications (e.g., dulaglutide and semaglutide) taken over the same duration, TZP showed a superior decrease in body fat compartments (i.e., total FM, VAT and WC). Finally, the effect of TZP on fat-free mass (FFM) is still uncertain because the findings remain inconclusive. In conclusion, TZP appears to be an effective strategy for achieving significant improvements in body fat and its distribution, but additional investigations are still needed to determine the impact of TZP on lean mass in this population.

RESUMEN

PURPOSE: The utility of repeating ultrasound-guided fine-needle aspiration (US-FNAB) in the follow-up of benign (THY2) thyroid nodules is still debated. The aim of this study was to retrospectively investigate the diagnostic value of re-biopsy of thyroid nodules following an initially benign result. METHODS: We retrospectively analyzed US-FNABs performed at the Unit of Endocrinology of Modena from 2006 to 2009. The firstly benign cytological result was compared with the cytological results of subsequent US-FNABs (2nd and/or 3rd) executed on the same nodule. RESULTS: Among 10449 US-FNABs, 6270 (60%) received a THY2 cytological categorization. Of them, 278 (4.43%) underwent a subsequent US-FNAB: 86.7% maintained the same cytology, 32 (11.5%) changed to THY3 (indeterminate) and 5 (1.8%) to THY4 (suspicious of malignancy). Among the 24 nodules addressed to surgery, 9 (37%) were histologically malignant, with an overall miss rate of 3.2%. Male patients had higher risk of discordant results at subsequent US-FNAB (p = 0.005, OR:3.59, 95%CI:1.453-7.769) while dimensional increase above 5 mm was predictive of concordant benign cytology (p = 0.036, OR:0.249, 95%CI:0.068-0.915). Age, suspicious US characteristics, and distance between US-FNABs resulted not predictive. CONCLUSIONS: Re-biopsy of benign nodules confirmed the benign nature in most cases. In case of discordant cytology, relocation in indeterminate category was the most common. The histological diagnosis of cancer occurred in one quarter of nodules surgically removed, with a low overall clinically significant miss rate. Thus, a small percentage of false negatives exists; males and subjects with US suspicious nodules should be carefully followed-up, considering case by case re-biopsy possibility.

RESUMEN

OBJECTIVE: Despite having normal thyroid-stimulating hormone levels, many hypothyroid patients are dissatisfied with the treatment. The primary aim of this study was to evaluate the effect of twice-daily, combination therapy with levothyroxine (LT4) and liothyronine (LT3), at doses adapted according to TSH-level, on peripheral tissues as reflected by sex hormone binding globulin (SHBG) levels in totally thyroidectomized patients. Changes in other tissue markers and quality of life considering DIO2-rs225014 and MCT10-rs17606253 genetic variants were also assessed. DESIGN: Double-blind, randomized, placebo-controlled. METHODS: One hundred and forty-one subjects were randomized to LT4 + LT3 group (LT4 + LT3 in the morning and LT3 in the evening; n = 70) or placebo group (LT4 in the morning and placebo in the evening; n = 71). Pituitary-thyroid axis compensation was assessed after 6, 12, and 24 weeks. Clinical parameters, quality of life, and tissue markers (sex hormone binding globulin, serum lipids, bone markers) were evaluated at 12 and 24 weeks. DIO2 and MCT10 single nucleotide polymorphisms were genotyped. RESULTS: The LT4 + LT3 group was treated with mean daily LT3 doses of 5.00 µg, with a mean daily LT4 reduction of 15 µg. After 6 months of treatment, neither SHBG and other tissue markers nor quality of life differed significantly between groups. Combination treatment required greater dose adjustments than placebo (25% vs 54%, P < .001), due to thyroid-stimulating hormone reduction, without hyperthyroidism signs or symptoms. At the end of treatment, the LT4 + placebo group had significantly lower fT3/fT4 compared to the LT4 + LT3 group (0.26 ± 0.05 vs 0.32 ± 0.08, P < .001). No preference for combination therapy was found. Genetic variants did not influence any outcomes. CONCLUSIONS: Six months of combination therapy with twice-daily LT3 dose adapted according to TSH-level do not significantly change peripheral tissue response or quality of life, despite an increase in the fT3/fT4 ratio.

RESUMEN

HIV-infected individuals suffer from accelerated aging, which manifests as premature cardiovascular and bone disease. However, little is known of the association of these two disorders in the HIV population. Our objective was to investigate the association between a marker of atherosclerosis (coronary artery calcium [CAC]) and low bone mineral density (BMD) in a cross-sectional cohort of HIV-infected patients. The study was conducted at the University of Modena and Reggio Emilia, Italy. A total of 636 consecutive middle-aged, HIV-infected subjects were recruited between January 2006 and December 2010. All patients underwent CAC and BMD assessment. Patients were categorized according to a CAC score <100 or >100 units based on previous literature that identified this cut-point as a marker of increased risk. Low femoral and lumbar spine BMD was defined as <25th percentile value for the study cohort. Logistic regression and bootstrap analysis were used to assess the independent association between CAC and BMD. The main outcome measure was a CAC score >100. Patients with CAC > 100 were older and more likely to be men, diabetic, and overweight. Patients with CAC < 100 had better renal function and a lower cardiovascular risk profile. After adjusting for age, sex, traditional and HIV-specific risk factors, vitamin D level, and PTH level, there was a significant association between CAC > 100 and low BMD for the femur (OR = 2.33, 95 % CI 1.09-4.99; p = 0.02) but not for the spine. Bootstrap analyses confirmed these findings. In summary, CAC was independently associated with low femoral BMD in HIV-infected patients. Future studies should test whether therapies that attenuate cardiovascular risk in HIV favorably impact bone health.

RESUMEN

Hypogonadism is a frequent finding among men living with HIV (MLWH) and it seems to occur earlier in comparison with the general male population. Although the prevalence of hypogonadism in MLWH has significantly lowered thanks to advancements in medical management, it remains high if compared with age-matched HIV-uninfected men, ranging from 13% to 40% in the age group of 20-60 years. Signs and symptoms of low serum testosterone (T) in MLWH are cause of concern since they are non-specific, of mild-to-moderate degree, and often overlapping with those of infection per se. For these reasons, hypogonadism can be underestimated in the absence of targeted laboratory blood examinations. With regard to the etiological factors involved in the T decrease, emerging evidence has suggested the functional nature of hypogonadism in MLWH, pointing out the mutual relationship between sex steroids, health status, comorbidities, and HIV-related factors. In agreement with this hypothesis, a therapeutic approach aiming at improving or reversing concomitant diseases through lifestyle changes (e.g. physical activity) rather than pharmacological T treatment should be theoretically considered. However, considering both patient's barriers to lifestyle changes to be maintained overtime and the lack of evidence-based data on the efficacy of lifestyle changes in normalizing serum T in MLWH, T therapy remains an option when other non-pharmacological interventions are ineffective as well as for all other functional forms of hypogonadism. From this perspective, the traditional therapeutic management of male hypogonadism in MLWH, especially the role of T supplementation, should be revised in the light of the probable functional nature of hypogonadism by considering a good balance between benefits and harmful. This narrative review presents an overview of current knowledge on hypogonadism in MLWH, deepening the factors driving and taking part in T decrease, providing advice for the clinical approach, and underlining the importance of individualized treatment aiming at optimizing non-gonadal comorbidities and thus avoiding over-, or even unnecessary, treatment with T.

RESUMEN

Objective: The serum calcium (Ca)-to-phosphorus (P) ratio has been proposed to identify patients with primary hyperparathyroidism and chronic hypoparathyroidism (HPT), but it has never been tested in pseudohypoparathyroidism (PHP). The aim of this study was to test the performance of Ca/P ratio in PHP diagnosis compared with that in healthy subjects and patients with HPT for differential diagnosis. Design: A retrospective, cross-sectional, and observational study was carried out. Methods: Serum Ca, P, creatinine, parathyroid hormone (PTH), and albumin were collected. Ca and P were expressed in mmol/L. Ca/P diagnostic performance was evaluated by receiver operating characteristic curve, sensitivity, specificity, and accuracy. Results: A total of 60 patients with PHP, 60 patients with HPT, and 120 controls were enrolled. The Ca/P ratio was lower in patients with PHP and HPT than that in controls (p < 0.0001). The cutoff of 1.78 (2.32 if Ca and P measured in mg/dL) for Ca/P ratio could identify patients with PHP and HPT among the entire cohort (sensitivity and specificity of 76%). No valid cutoff of Ca/P was found to distinguish patients with PHP from patients with HPT; in this case, PTH above 53.0 ng/dL identified patients with PHP (sensitivity and specificity of 100%). The index (Ca/P × PTH) above 116 ng/L recognized patients with PHP from controls (sensitivity of 84.7% and specificity of 87.4%), whereas (Ca/P × PTH) below 34 ng/L recognized patients with HPT from controls (sensitivity of 88.9% and specificity of 90.8%). Conclusions: The Ca/P ratio below 1.78 (2.32 CU) is highly accurate to identify patients with PHP and HPT, although it is not reliable to differentiate these two conditions. The index (Ca/P × PTH) is excellent to specifically recognize PHP or HPT from healthy subjects.

RESUMEN

Summary: A 44-year-old athletic man presented in 2009 with severe low back pain. Dual-energy x-ray absorptiometry revealed severe osteoporosis; serum testosterone was 189 ng/dL while serum estradiol (E2) measured by liquid chromatography/mass spectrometry was 8 pg/mL. DNA was extracted and sequenced from a blood sample from the patient since his maternal first cousin also had low bone mass and both patients were screened for aromatase dysfunction by PCR analysis for the CYP19A1 gene, which encodes aromatase. No known pathologic mutations were observed in the coding exons, but novel single nucleotide polymorphisms were detected both in the proband and in his cousin. Treatment with topical testosterone started in August 2010. Over the next 8 years, testosterone dosage was varied and switched from topical gel to injections and maintained on depo-injections of testosterone at about 60 mg once per week. Re-examination in March 2012 included a brain MRI to exclude pituitary lesions; hyperparathyroidism was ruled out (normal serum parathyroid hormone, calcium, and calcium to phosphorous ratio) and celiac disease was excluded (negative transglutaminase antibodies). Follow-up in October 2018 showed improved bone mineral density of the lumbar spine by 29% and of the left femoral hip by 15% compared to baseline measurements. This reveals the importance of measuring serum E2 for making the correct diagnosis, as well as for monitoring a therapeutic effect. Herein, we propose treatment of male osteoporosis where serum E2 levels are below about 20 pg/mL with testosterone to reverse osteoporosis. Learning points: Estrogen deficiency in the diagnosis of male idiopathic osteoporosis. Importance of serum estradiol in male osteoporosis. Role of polymorphisms in aromatase gene on bone health. Reversal of osteoporosis. Tailored testosterone treatment for bone health.

RESUMEN

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.

RESUMEN

(1) Background: While females start their gynecological examinations during puberty, only few men decide to be visited by urologists in their youth. Given the participation in the EcoFoodFertility research project, our department had the opportunity to screen young males that were supposedly healthy. (2) Results: from January 2019 to July 2020, we evaluated 157 patients with sperm, blood analysis, and uroandrological examinations. The inclusion criteria were age 18-40 and absence of previous urological disease (urology-naïve). The primary endpoint of the study was to record uroandrological diseases that are occasionally discovered during examination in asymptomatic young men. The average age was 26.9 years (range 18-40); average testicular volume was 15.7 mL (range 12-22 mL); and 45.2% reported abnormal semen analysis: 62 cases of teratozoospermia, 27 asthenozoospermia, 18 oligozoospermia, and 2 azoospermia were discovered respectively; 4/157 patients were diagnosed with hypogonadism; 2 cases with suspicious testicular mass resulted in testicular cancer; and 31 suspected varicoceles and 8 patients with mild sexual dysfunctions were managed. (3) Conclusions: an uroandrological evaluation of young asymptomatic males allowed for the prompt diagnosis of different urological conditions, including cancerous ones, in our series. Despite being debatable, combining urological counselling with physical examination, semen analysis, and a laboratory profile could be useful and cost-effective in order to ameliorate male health.

RESUMEN

OBJECTIVE: The objectives of this study were to describe the trajectories of bone mineral density (BMD) and trabecular bone score (TBS) changes throughout pre-menopause (reproductive phase and menopausal transition) and post-menopause (early and late menopause) in women with HIV (WWH) undergoing different antiretroviral therapies (ARTs) and explore the risk factors associated with those changes. METHODS: This was an observational longitudinal retrospective study in WWH with a minimum of two DEXA evaluations comprising BMD and TBS measurements, both in the pre-menopausal and post-menopausal periods. Menopause was determined according to the STRAW+10 criteria, comprising four periods: the reproductive period, menopausal transition, and early- and late-menopausal periods. Mixed-effects models were fitted to estimate the trajectories of the two outcomes (BMD and TBS) over time. Annualized lumbar BMD and TBS absolute and percentage changes were calculated in each STRAW+10 time window. A backward elimination procedure was applied to obtain the final model, including the predictors that affected the trajectories of BMD or TBS over time. RESULTS: A total of 202 WWH, all Caucasian, were included. In detail, 1954 BMD and 195 TBS data were analyzed. The median number of DEXA evaluations per woman was 10 (IQR: 7, 12). The median observation periods per patient were 12.0 years (IQR = 8.9-14.4) for BMD and 6.0 years (IQR: 4.3, 7.9) for TBS. The prevalence of osteopenia (63% vs. 76%; p < 0.001) and osteoporosis (16% vs. 36%; p < 0.001) increased significantly between the pre-menopausal and post-menopausal periods. Both BMD (1.03 (±0.14) vs. 0.92 (±0.12) g/cm2; p < 0.001) and TBS (1.41 (IQR: 1.35, 1.45) vs. 1.32 (IQR: 1.28, 1.39); p < 0.001) decreased significantly between the two periods. The trend in BMD decreased across the four STRAW+10 periods, with a slight attenuation only in the late-menopausal period when compared with the other intervals. The TBS slope did not significantly change throughout menopause. The delta mean values of TBS in WWH were lower between the menopausal transition and reproductive period compared with the difference between menopause and menopausal transition. CONCLUSIONS: Both BMD and TBS significantly decreased over time. The slope of the change in BMD and TBS significantly decreased in the menopausal transition, suggesting that this period should be considered by clinicians as a key time during which to assess bone health and modifiable risk factors in WWH.

RESUMEN

INTRODUCTION: Erectile dysfunction (ED) is common among elderly men and patients suffering from chronic diseases, the latter probably including also HIV infection. No studies, however, compared the prevalence of ED in HIV-infected and HIV-uninfected individuals using the international index of erectile function (IIEF-15). AIM: The aim of this study is to compare ED prevalence in young to middle-aged men with and without HIV infection using the IIEF-15 questionnaire. METHODS: We conducted a cross-sectional, observational, controlled study on 444 HIV-infected men and 71 HIV-uninfected men. MAIN OUTCOMES MEASURES: The IIEF-15 questionnaire was used to assess ED. A cutoff score of ≤25 of the erectile domain was used to diagnose ED. Serum testosterone, demographic, and anthropometric (weight, height, and body mass index [BMI]) characteristics were obtained from all participants. Statistics included the T-test, the Fisher's test, univariable and multivariable logistic regression, and univariate and multivariate Spearman's correlation analysis. RESULTS: The HIV-uninfected group was significantly younger than the HIV-infected group and presented a higher BMI (P < 0.001). The prevalence of mild, moderate, and severe ED was higher in HIV-infected men than in HIV-uninfected men of all decades of age. In univariate analysis, HIV infection was associated with ED (odds ratio [OR] = 34.19, P < 0.001). In multivariable logistic regression analysis, HIV infection remained the strongest predictors of ED (OR = 42.26, P < 0.001) followed by hypogonadism, after adjusting for age and BMI. CONCLUSIONS: This study demonstrates a clear association between ED and HIV infection, after adjusting for age and BMI. Other than HIV infection, hypogonadism was associated with ED. In addition, the prevalence of ED was higher in HIV-infected men than in HIV-uninfected men, in all decades of age. The early onset of ED in HIV-infected men could be considered a peculiar clinical hallmark of HIV and confirms precocious aging in these patients. ED should be of concern to clinicians when managing HIV-infected men even if the latter are young or middle aged.

RESUMEN

INTRODUCTION: The penis has been compared to a barometer of endothelial health, erectile dysfunction (ED) being an early sign of endothelial dysfunction. AIM: The aim of the study was to investigate the extent of the association between ED and endothelial dysfunction in patients with human immunodeficiency virus (HIV) infection on antiretroviral therapy. METHODS: In this observational cross-sectional study, we evaluated the prevalence and factors associated with ED in a cohort of 133 HIV-infected men. MAIN OUTCOME MEASURES: The International Index of Erectile Function, ultrasound assessment of brachial artery flow mediated dilatation (FMD), and multi-slice computed tomography for coronary artery calcifications (CAC) as surrogates of endothelial dysfunction, the Adult Treatment Panel III criteria to diagnose metabolic syndrome (MS), plasma total testosterone (hypogonadism), and a visual analogue scale (VAS) of aesthetic satisfaction of the face and of the body (psychological distress associated with lipodystrophy). RESULTS: Thirty-nine (29.32%) patients had mild ED, 14 (10.52%) patients had moderate ED, and 26 (19.55%) patients had severe ED. Prevalence of ED ranged from 45% to 65%, respectively, in patients less than 40 and more than 60 years old. MS was present in 20 (25%) patients with ED and 13 (24%) patients without ED (P value = 0.87). Prevalence of ED neither appeared to be associated with MS as a single clinical pathological entity nor with the numbers of its diagnostic components. FMD < 7% was present in 25 (32%) patients with ED and 18 (33%) patients without ED (P value = 0.83), and CAC > 100 was present in 8 (10%) patients with ED and 5 (9%) patients without ED (P value = 0.87). A stepwise multivariable logistic regression analysis was used to find predictors of ED. Independent predictors were VAS face (odds ratio [OR] = 0.85, 95% confidence interval [CI] 0.73-0.99, P = 0.049) and age per 10 years of increase (OR = 1.73, 95% CI 1.02-2.94, P = 0.04). CONCLUSIONS: Age constituted the most important risk factor for ED, which was related to aesthetic dissatisfaction of the face leading to negative body image perception.

RESUMEN

INTRODUCTION: Although a trustworthy connection between doctor and patient is crucial in clinical practice, it could be hindered by different cultural and linguistic backgrounds. Moreover, an effective doctor-patient interaction could be even more challenging in andrological fields, in which psychological and social components are predominant. AIM: To analyse the doctor-patient relationship in the andrological field, applying both qualitative and quantitative analyses. METHODS: monocentric, cross-sectional, observational study was performed between May and December 2018. During the study, all patients aged >18 years attending the Modena Andrology Unit for couple infertility or erectile dysfunction were enrolled and the doctor-patients interaction recorded. Patients were divided into two groups depending on their medical seeking and were further divided between native and non-native speakers of Italian. All patients underwent a routine andrological examination. Every first medical consultation was audio-recorded and transcribed using "ELAN" software for socio-linguistic analysis. Transcriptions underwent qualitative analysis through conversation analysis. Then, quantitative analyses were performed, and interaction parameters underwent correlation analyses. RESULTS: Twenty-five patients were enrolled. The analysis of the andrological interview allowed to recognise five consecutive phases, following a semi-standardized pattern. Patients without linguistic barriers and with infertility problems showed more autonomous contribution during the consultation. No difference arose in the sexual dysfunctions group. Doctor's explanations were frequent, but when linguistic barrier was present or Italian patients seemed less talkative, explanations were shorter, and doctors tried to use other conversational mechanisms to promote understanding. Patient's variables were significantly lower compared to the doctor, considering the number of turns (p = 0.025) and their minimum (p = 0.032), maximum (p < 0.001), and average durations (p < 0.001). Only patient's latency was significantly higher than the doctor's (p = 0.001). CONCLUSION: This is the first attempt to analyse the doctor-patient relationship in andrology using authentic audio-recorded consultations. The results confirmed that a patient-centred communication must be applied also in andrological consultations. However, the topics discussed may require more "medical formulation" to be acceptable to the participants in this context.

RESUMEN

Over the past two decades several large cohort studies have been performed to disclose the changes of sex hormone in elderly and their clinical significance. Beyond the decline of total testosterone, aging is accompanied by a sex hormone binding globulin (SHBG) increase, a steeper free testosterone decline, while gonadotropins may be increased or inappropriately normal, with important contribution of comorbidities (e.g., obesity) to these changes. Actually, it has become firm the concept that the biochemical finding of testosterone deficiency alone is not sufficient for diagnosing hypogonadism in older men. The definition of late-onset hypogonadism (LOH) includes low serum testosterone levels coupled with signs and symptoms related to hypogonadism. Indeed, the combination of multiple factors all contributing to the testosterone decline, with other concurrent comorbidities further overlapping, makes the clinical correlates of LOH highly heterogeneous. For all these reasons both the diagnosis and the therapeutic management of LOH, especially the decision about starting testosterone replacement treatment, remain challenging.
