The prevalence of hypogonadism in HIV-infected patients is still a matter of debate as there is no standardized consensual diagnostic method. In addition, the etiology and endocrine/metabolic implications of hypogonadism in this population remain controversial. This study aims to determine the prevalence of testosterone deficiency in a single-site hospital and to evaluate its association with potential risk factors, lipodystrophy, metabolic syndrome, and cardiovascular risk. This study analyzed 245 HIV-infected men on combined antiretroviral therapy. Patients with low total testosterone (TT) levels (<2.8 ng/mL) and/or low calculated free testosterone (FT) levels (<6.5 ng/dL) were considered testosterone deficient. According to their LH and FSH levels, patients were classified as having hypogonadotropic or hypergonadotropic dysfunction. Other clinical, anthropometric, and analytic parameters were also collected and analyzed. The prevalence of testosterone deficiency in our population was 29.4 %. Among them, 56.9 % had hypogonadotropic dysfunction and 43.1 % presented with hypergonadotropic dysfunction. Patients with testosterone deficiency were older (p < 0.001), had higher HbA1c levels (p = 0.016) and higher systolic blood pressure (p = 0.007). Patients with lower testosterone levels had higher prevalence of isolated central fat accumulation (p = 0.015) and had higher median cardiovascular risk at 10 years as measured by the Framingham Risk Score (p = 0.004) and 10-Year ASCVD risk (p = 0.002). The prevalence of testosterone deficiency in this HIV population is high, with hypogonadotropic dysfunction being responsible for the majority of cases. Testosterone deficiency might predispose to, or be involved, in the pathogenesis of HIV-associated lipodystrophy. Patients with low testosterone levels have higher cardiovascular risk, highlighting the importance of early diagnosis of this condition.

Purpose: While tuberculosis remains a significant global health concern, prosthetic joint infections (PJIs) caused by members of the Mycobacterium tuberculosis complex are exceptionally rare. Our objective is to perform a retrospective search of new cases of this disease and analyze all cases available in the literature of tuberculous PJIs, aiming to detect factors that may influence patient outcomes. Methods: The ESGIAI and ESGMYC study groups were used to collect information on non-published cases of tuberculous prosthetic joint infections (PJIs). Additionally, a literature review of all published cases of tuberculous PJIs was conducted. All identified cases in the retrospective study and in the literature review were merged and included in the statistical analysis, involving both univariate and multivariate analyses. Results: Fifteen previously unreported cases of tuberculous prosthetic joint infections (PJIs) from four countries were detailed. Among them, ten patients were female, with a median age of 76 years. The hip was affected in 13 cases. Seven patients experienced co-infection with another microorganism. Treatment approaches varied, with 13 patients undergoing implant removal, one treated with DAIR (debridement, antibiotics, and implant retention), and one case was treated with an unknown treatment method. All patients received antibiotic therapy and achieved a cure. The literature review that was conducted detected 155 published cases. Univariate analysis revealed a statistical significance for previous tuberculosis, joint, and no importance of surgery for cure. Conclusions: Tuberculous prosthetic joint infection (PJI) is a rare condition, typically presenting as a localized chronic infection. Antibiotic treatment is essential for the management of these patients, but neither surgical treatment nor duration of treatment seems to have importance in the outcome.

Prostatitis is a clinical condition of difficult management and with limited antimicrobial options, especially in the setting of antimicrobial resistance. Recurrences are frequent and can be severe. Limited reports support the use of fosfomycin for chronic prostatitis by ESBL-producing bacteria. We reported a case of a patient with chronic prostatitis caused by ESBL-producing Escherischia coli with several relapses after prolonged periods of treatment with broad-spectrum intravenous antibiotic therapy and with recurring urinary symptoms after transuretheral prostatic resection. After resolution of the last infection, we performed a long-term eradication antimicrobial treatment with 3 g of fosfomycin once daily, altered to 3 g every 48 h after 10 days due to diarrhea (which resolved with the dose change). After three months with this dosage, fosfomycin was switched to a once-weekly regimen which was maintained for further 9 months. After 9 months of follow-up without antimicrobial treatment, the patient has remained free of urinary symptoms. Experience with fosfomycin for chronic prostatitis caused by ESBL-producing E. coli is limited to three case reports and two case series. Intraprostatic measurements have shown adequate penetration of fosfomycin into prostatic tissue. Accordingly, our report suggests that fosfomycin can be used as eradication therapy in a patient with a prior history of chronic prostatitis by ESBL-producing bacteria with recurring urinary infections after surgical treatment.
