Introduction: Remdesivir (REM) and monoclonal antibodies (mAbs) could alleviate severe COVID-19 in at-risk outpatients. However, data on their use in hospitalized patients, particularly in elderly or immunocompromised hosts, are lacking. Methods: All consecutive patients hospitalized with COVID-19 at our unit from 1 July 2021 to 15 March 2022 were retrospectively enrolled. The primary outcome was the progression to severe COVID-19 (P/F < 200). Descriptive statistics, a Cox univariate–multivariate model, and an inverse probability treatment-weighted (IPTW) analysis were performed. Results: Overall, 331 subjects were included; their median (q1–q3) age was 71 (51–80) years, and they were males in 52% of the cases. Of them, 78 (23%) developed severe COVID-19. All-cause in-hospital mortality was 14%; it was higher in those with disease progression (36% vs. 7%, p < 0.001). REM and mAbs resulted in a 7% (95%CI = 3–11%) and 14% (95%CI = 3–25%) reduction in the risk of severe COVID-19, respectively, after adjusting the analysis with the IPTW. In addition, by evaluating only immunocompromised hosts, the combination of REM and mAbs was associated with a significantly lower incidence of severe COVID-19 (aHR = 0.06, 95%CI = 0.02–0.77) when compared with monotherapy. Conclusions: REM and mAbs may reduce the risk of COVID-19 progression in hospitalized patients. Importantly, in immunocompromised hosts, the combination of mAbs and REM may be beneficial.

Background: The increased vascular risk associated with varicella–zoster virus (VZV) reactivation is extensively established in the general population. This retrospective cohort study investigates whether this observation holds for People Living with HIV (PLWH), a group already confronting heightened cardiovascular risk. Methods: Among PLWH who initiated antiretroviral therapy (ART) at our center and have been under our care for >24 months since 1st January 2005, individuals with a history of herpes zoster (HZ) were identified, and their features were compared with those of PLWH with no history of HZ. The prevalence of ischemic events (deep venous thrombosis, stroke, and acute myocardial infarction) was calculated and compared using the chi-square test. An odds ratio (O.R.) and a 95% confidence interval (C.I.) for ischemic events following HZ were evaluated through univariate and multivariate logistic regression. Results: Overall, 45/581 PLWH reported HZ. Ischemic events followed HZ significantly more often than not (13% vs. 5%, p = 0.01). Positive serology for both VZV and HZ correlated with increased ischemic risk (O.R. 4.01, 95% C.I. 1.38–11.6, p = 0.01 and O.R. 3.14, 95% C.I. 1.12–7.68, p = 0.02, respectively), though chronic heart disease demonstrated stronger predictive value in multivariate analysis(O.R. 8.68, 95% C.I. 2.49–29.50, p = 0.001). Conclusions: VZV potentially exacerbates vascular risk in PLWH, particularly in the presence of other predisposing factors. Further research is needed to confirm our data.

Background: Limited evidence is available about sleep quality changes associated with the use of Cabotegravir (CAB), a new, long-acting (LA) antiretroviral (ARV) drug belonging to the class of Integrase Strand Transfer Inhibitors (INSTIs). Methods: Pittsburgh Sleep Quality Index (PSQI) was calculated in 53 people living with HIV (PLWH) under the care of the outpatient services of two Italian Infectious Diseases Centers in Apuliabefore (M0) and seven months after (M7) the switch to LA CAB. Global scores and relative subitems were compared using paired sample tests. The same analysis was repeated in subgroups of PLWH switching from INSTIs-, Dolutegravir-(DTG), and Bictegravir (BIC)-based regimens. Results: A significant reduction was reported in global mean (±StandardDeviation, SD) PSQI at M7 compared to M0 (4 (±3) vs. 3 (±2), p = 0.01), particularly in the areas of sleep latency and sleep disturbances. The improvement was also significant in PLWH already on INSTIs- (from median 3 to 2 points, p = 0.02) and DTG-based (from median 4 to 2, p = 0.01) ARV regimens, but not among those who switched from BIC-based regimens. Conclusions: PLWH reported improved sleep quality after switching from ARV treatment to LA CAB. Further studies are needed to give deeper insights into this phenomenon.

Both positive serology for VZV and HZ correlated with increased ischemic risk (O.R. 4.01, 95% C.I. 1.38-11.6, p=0.01 and O.R. 3.14, 95% C.I. 1.12-7.68, p=0.02, respectively), though pre-existing heart disease demonstrated stronger predictive value in multivariate analysis(O.R. 8.68, 95% C.I. 2.49-29.50, p=0.001). Conclusions: VZV potentially exacerbates vascular risk for PLWH, particularly in the presence of other predisposing factors. Further research is needed to confirm our data.
