We aimed to describe the impact of this screening on the local SARS-CoV-2 outbreak. All high-risk contacts, as well as the individuals living in their households, were screened. We detailed the evolution of the number of confirmed COVID-19 cases in the Lot-et-Garonne department and the rest of the Nouvelle-Aquitaine region. Among the 89 screened individuals, 10 new cases were confirmed, including 4 asymptomatic persons. In Lot-et-Garonne, the number of confirmed COVID-19 cases immediately decreased after this screening and no epidemic peak occurred, contrary to what was observed in the rest of the region. The early screening of high-risk contacts of COVID-19 cases and members of their household implemented a few days before the first lockdown probably helped to prevent the spread of the virus in the department

Factors associated with poorer quality of life in people living with HIV in southwestern France in 2018–2020 (ANRS CO3 AQUIVIH-NA cohort: QuAliV study)
No full textAbstract We evaluated people living with Human Immunodeficiency Virus’ (PLWH) quality of life (QoL) and assessed whether their demographic, disease-related, socioeconomic, or behavioral characteristics were associated with poorer QoL. ANRS CO3 AQUIVIH-NA cohort participants (Nouvelle Aquitaine, France) were recruited to a cross-sectional study (2018–2020) and their QoL assessed (WHOQOL-BREF). We calculated median (Q1, Q3) QoL domain scores and assessed factors associated with poorer median QoL using bivariable and multivariable quartile regression. Of the 965 PLWH included, 98.4% were on antiretroviral therapy, 94.7% were virally-suppressed, 63.5% reported good/very good QoL. Median scores (0–100) were highest for physical (69;Q1, Q3: 56, 81) and environmental (69; 56, 75) QoL and lowest for social (56; 44, 69) and psychological (56; 44, 69) QoL. PLWH with ≥ 3 comorbidities, HIV-related stigma, or income of < 1500€/month had poorer median adjusted physical, psychological, social, and environmental QoL scores compared to reference groups. While more than half of PLWH reported good/very good QoL, we have not achieved good QoL in 90% of PLWH. Multi-morbidity, HIV-related stigma, and social determinants were consistently and independently associated with poorer QoL. Addressing structural factors in addition to those indirectly related to HIV is required to attain good QoL in all PLWH
T-cell activation discriminates subclasses of symptomatic primary humoral immunodeficiency diseases in adults.
No full textInternational audienceBACKGROUND: Symptomatic Primary Humoral Immunodeficiency Diseases (PHID) constitute a highly heterogeneous group of diseases characterized by a shared hypogammaglobulinemia, resulting in increased risk of recurrent or severe infections. Associations have been described with a variety of immunological abnormalities involving B and T-cell differentiation, T-cell activation and innate immunity. However, PHID discrimination remains based on B-lymphocyte abnormalities and other components of the immune system have not been sufficiently taken into account. We carried out unsupervised and supervised methods for classification in a cohort of 81 symptomatic PHID patients to evaluate the relative importance of 23 immunological parameters and to select relevant markers that may be useful for diagnosis and prognosis. RESULTS: We identified five groups of patients, among which the percentage of PHID complications varied substantially. Combining the set of markers involved in PHID supported the existence of two distinct mechanisms associated with complications. Switched memory B-cell attrition and CD8+ HLA-DR + activated T-cell increase were the prominent abnormalities observed in PHID complications. Furthermore, in a subgroup of 57 patients with common variable immunodeficiency, the classification that added CD8+ HLA-DR + to the consensual EUROclass classification was better than the EUROclass model in predicting complications. CONCLUSION: These results highlight the importance of T-cell activation that may improve discrimination of PHID patients in specific subgroups and help to identify patients with different clinical outcomes
Time to treatment initiation and HIV viral suppression in people diagnosed with HIV-1 during COVID-19 pandemic in ex-Aquitaine, France (ANRS CO3 AQUIVIH-NA Cohort-QuAliCOV Study)
No full textInternational audienceThe Covid-19 pandemic's impact on initiation and effectiveness of antiretroviral therapy (ART) in people diagnosed with HIV remains unclear. We evaluated critical delays in HIV care in people diagnosed before and during the pandemic in ex-Aquitaine, France. We considered adults diagnosed with HIV-1 in 2018-2021 and enrolled in the ANRS CO3 AQUIVIH-NA and followed them until 10/10/2022 for those diagnosed during the pandemic (1/4/2020 - 31/12/2021) and until 31/03/2020 for historical controls. We compared their characteristics at inclusion and the median time between diagnosis and ART initiation, ART initiation and viral suppression and diagnosis and virological suppression (effective management). 83 individuals were diagnosed during the pandemic versus 188 during the pre-pandemic period. Median follow-up was 549 (IQR: 329-713) days. Populations were similar in terms of sex, age, HIV transmission group, hospital type, and clinical characteristics at diagnosis, however, fewer were foreign-born during the pandemic (15.7% versus 33.5%, p=0.003). The probability of ART initiation, therapeutic success, effective management was higher in PLWH diagnosed during the pandemic in adjusted analyses (HR 2.0 95%CI. 1.5-2.7, HR 1.7 95%CI. 1.2-2.3, HR 1.8 95%CI. 1.3-2.6, respectively). Those diagnosed during the pandemic were 2.3 (95%CI: 1.2-4.1) times more likely to be virologically suppressed within 6 months of diagnosis compared to historical controls. Pandemic-related reorganizations may have resulted in newly diagnosed PLWH being prioritized, however, the lower proportion of foreign-born PLWH diagnosed during the pandemic period, likely due to reduced migration and potential delays in diagnosis, may contribute to these preliminary findings
