Intermittent doravirine/lamivudine/tenofovir disoproxil fumarate (DOR/3TC/TDF) maintains a high level of viral suppression in virologically suppressed people living with HIV.

INTRODUCTION: We aimed to determine whether doravirine/lamivudine/tenofovir disoproxil fumarate (DOR/3TC/TDF) given 5 or 4 days a week was able to maintain viral suppression in people living with HIV (PLHIV). METHODS: In this observational, retrospective study, we included all PLHIVs who had received intermittent DOR/3TC/TDF between 10/01/2019 and 01/31/2021, in two French hospitals. RESULTS: Forty-three PLHIVs were included, median (IQR) age: 52 years (48-58), ART duration: 15 years (8-23), duration of virological suppression: 6 years (2-10). Median follow-up was 78 weeks (IQR 62-97). One virological failure (VF) occurred at W38 (HIV-RNA = 61 and 76 copies/mL), in a patient with no viral resistance at baseline or at time of VF, and during the study period five individuals discontinued DOR/3TC/TDF due to adverse events. There were no significant changes during follow-up in the CD4 count, CD4/CD8 ratio, body weight or residual viremia rate. CONCLUSION: These findings suggest the potential for intermittent DOR/3TC/TDF to maintain virological control.

The first wave of COVID-19 in hospital staff members of a tertiary care hospital in the greater Paris area: A surveillance and risk factors study.

INTRODUCTION: Understanding how hospital staff members (HSMs), including healthcare workers, acquired severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first wave can guide the control measures in the current second wave in Europe. METHODS: From March 5 to May 10, 2020, the Raymond-Poincaré Hospital held a weekday consultation for HSMs for PCR testing. HSMs were requested to complete a questionnaire on their potential exposure to SARS-CoV-2. RESULTS: Of 200 HSMs screened, 70 tested positive for SARS-CoV-2. Ninety-nine HSMs completed the questionnaire of whom 28 tested positive for SARS-CoV-2. In the multivariable analysis, age of ≥44 years (aOR = 5.2, 95% CI [1.4-22.5]) and not systematically using a facemask when caring for a patient (aOR = 13.9, 95% CI [1.8-293.0]) were significantly associated with SARS-CoV-2 infection. Working in a COVID-19-dedicated ward (aOR = 0.7, 95% CI [0.2-3.2]) was not significantly associated with infection. Community-related exposure in and outside the hospital, hospital meetings without facemasks (aOR = 21.3, 95% CI [4.5-143.9]) and private gatherings (aOR = 10, 95% CI [1.3-91.0]) were significantly associated with infection. CONCLUSIONS: Our results support the effectiveness of barrier precautions and highlight in-hospital infections not related to patient care and infections related to exposure in the community. Protecting HSMs against COVID-19 is crucial in fighting the second wave of the epidemic.

Clinical Cutaneous Features of Patients Infected With SARS-CoV-2 Hospitalized for Pneumonia: A Cross-sectional Study.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a current pandemic worldwide. This virus can reach all organs and disturbs the immune system, leading to a cytokine storm in severe forms. We aimed to report cutaneous features among coronavirus disease 2019 (COVID-19) hospitalized patients. METHODS: We performed a cross-sectional study on 1 given day among all patients hospitalized in acute care for COVID-19 and included all patients with cutaneous features. Follow-up 48 hours later was obtained. RESULTS: Among 59 adult patients hospitalized on the day of the study in an infectious diseases ward for SARS-CoV-2 infection who were confirmed by molecular assay and/or radiological findings (computed tomography scan), 40 were included. Several cutaneous manifestations were found: macular exanthema (80%), face edema (32%), livedo (13%), urticarial rash (8%), purpura (5%), oral lichenoid lesions (33%), and conjunctivitis (18%). Cutaneous biopsy was performed in 17 patients. Histological findings showed mast cell hyperplasia (100%), superficial perivascular infiltrate of lymphocytes (94%), and superficial edema (47%) consistent with capillary leak. CONCLUSIONS: Various dermatological signs can be encountered during COVID-19. A macular rash was the most frequent. All cutaneous features could be related to a vascular leak process.

Efficacy of intermittent short cycles of integrase inhibitor-based maintenance ART in virologically suppressed HIV patients.

BACKGROUND: Several studies have shown that NNRTI/PI-based triple therapy could be safely administered as a 4 days (4D) or 5 days (5D) a week maintenance strategy. We report here our experience of using an integrase inhibitor (INSTI)-based 4D/5D regimen in virologically suppressed HIV patients. METHODS: This cohort study enrolled adult patients on ART with viral load (VL) <50 copies/mL for >1 year, who switched to an INSTI-based triple regimen given 4D/5D a week. The primary endpoint was the virological efficacy rate at Week (W) 48, with virological failure defined as confirmed VL ≥50 copies/mL. RESULTS: A total of 73 patients were included (n = 28 for 4D, n = 45 for 5D): 54 men (74%), median (IQR) age 51 (45-57) years, ART duration 10 (6-18) years and duration of viral suppression 5 (2-9) years at baseline. As of 25 March 2019, the median follow-up was 21 (14-35) months, with a total of 161 patient-years of follow-up; all patients had reached the W24 visit, 66 (90%) W48 and 34 (47%) W96. Four patients discontinued the strategy: virological failure (n = 2) at W60 and W67, respectively, switch for renal toxicity (n = 1) at W28 and switch to rilpivirine/dolutegravir (n = 1) at W65. Overall the rate of virological success (95% CI) was 100% (94%-100%) at W24 and W48 and 93.7% (79.8%-98.2%) at W96. CONCLUSIONS: While waiting for the final results of the large randomized QUATUOR ANRS-170 study, our real-life results suggest that the use of an intermittent maintenance triple-drug regimen given as a weekend (2 or 3 days) off is as effective with an INSTI-based regimen as with a PI or an NNRTI.
