In the recent 2022 monkeypox (Mpox) global outbreak, cases have been mostly documented among men who have sex with men. Proctitis was reported in almost 14% of cases. In this study, four ...Mpox-confirmed cases requiring hospitalizations for severe proctitis were characterized by clinical, virological, microbiological, endoscopic, and histological aspects. The study showed the presence of lymphofollicular lesions associated with Mpox virus rectal infection for the first time.
Abstract
Background: The Raltegravir Switch for Toxicity or Adverse Events (RASTA) Study is a 2-arm randomized pilot study exploring the safety and efficacy at 48 weeks of a treatment switch to ...raltegravir associated with tenofovir/emtricitabine or abacavir/lamivudine in patients with regimens with optimal virological control. Methods: Patients treated with stable protease inhibitor (PI)-, non-nucleoside reverse transcriptase inhibitor (NNRTI)-, or nucleoside reverse transcriptase inhibitor (NRTI)-based regimens, with HIV-RNA levels < 50 copies/ml for ≥ 3 months and a CD4 cell count > 200 cells/μl were eligible. Enrollment of 40 patients was planned: at baseline patients were randomized 1:1 to switch to raltegravir plus tenofovir/emtricitabine (arm A) or abacavir/lamivudine (arm B). Laboratory parameters, raltegravir plasma levels, self- reported adherence, quality of life parameters, neurocognitive performance, bone composition, and body fat distribution were monitored. Virological failure was defined as HIV-RNA > 50 copies/ml on 2 consecutive determinations. Results: After 48 weeks, 5/40 (12.5%) regimen discontinuations occurred: 2 were for low-level viremia virological failure (both in arm A, at weeks 24 and 48) and 3 were for adverse events (neurological disturbances and skin rash in arm B; proximal tubulopathy in arm A). Overall, a significant CD4 increase was observed at weeks 36 and 48, and a significant decrease in total cholesterol, non-high density lipoprotein cholesterol, and triglycerides was observed at each study visit. Physical health/satisfaction in therapy scores and neuropsychological performance improved. The lumbar column Z-score improved, with no modification in other bone composition and fat distribution parameters. Conclusions: The investigated switch strategy was associated with rare virological failure. Improvements in lipid levels, quality of life measures, neuropsychological performance, and bone composition suggest good tolerability of raltegravir-based regimens.
