Seven years (2015-2021) of blood donor screening for HEV-RNA in France: lessons and perspectives.

International audienceThe French health authorities are considering expanding the current selective HEV-RNA testing procedure to include all donations in order to further reduce transfusion-transmitted HEV infection. Data obtained from blood donors (BDs) tested for HEV-RNA between 2015 and 2021 were used to assess the most efficient nucleic acid testing (NAT) strategy

Hepatitis A: an epidemiological survey in blood donors, France 2015 to 2017

International audienceSince mid-2016, hepatitis A virus (HAV) outbreaks, involving predominantly men who have sex with men (MSM), have affected countries in Europe and overseas. In France, HAV screening of blood donations in 2017 revealed a HAV-RNA prevalence ca fivefold higher than during 2015-16 (4.42/106 vs 0.86/106; p = 0.0005). In 2017, despite a higher male-to-female ratio (5.5 vs 0.7) and the identification of MSM-associated outbreak strains, only one of 11 infected male donors self-reported being a MSM. Since mid-2016, outbreaks involving mainly men who have sex with men (MSM) have been reported in European countries and overseas [1-6]. The outbreaks were associated with three genotype IA hepatitis A virus (HAV) strains: VDR_521_2016, RIVM_HAV16-090 and V16-25801. In this study, we report epidemiological and clinical findings pertaining to HAV infected blood donors before and during the recent outbreak in France

Quantitative-analysis of computed tomography in COVID-19 and non COVID-19 ARDS patients: A case-control study

International audienceHighlights• Lung weight is significantly increased in all COVID+ ARDS patients.• Lung potential for recruitment of COVID+ ARDS patients is lower than COVID− ARDS.• A substantial proportion of COVID+ patients exhibit large amount of tidal hyperinflation.PurposeThe aim of this study was to assess whether the computed tomography (CT) features of COVID-19 (COVID+) ARDS differ from those of non-COVID-19 (COVID−) ARDS patients.Materials and methodsThe study is a single-center prospective observational study performed on adults with ARDS onset ≤72 h and a PaO2/FiO2 ≤ 200 mmHg. CT scans were acquired at PEEP set using a PEEP-FiO2 table with VT adjusted to 6 ml/kg predicted body weight.Results22 patients were included, of whom 13 presented with COVID-19 ARDS. Lung weight was significantly higher in COVID− patients, but all COVID+ patients presented supranormal lung weight values. Noninflated lung tissue was significantly higher in COVID− patients (36 ± 14% vs. 26 ± 15% of total lung weight at end-expiration, p < 0.01). Tidal recruitment was significantly higher in COVID− patients (20 ± 12 vs. 9 ± 11% of VT, p < 0.05). Lung density histograms of 5 COVID+ patients with high elastance (type H) were similar to those of COVID− patients, while those of the 8 COVID+ patients with normal elastance (type L) displayed higher aerated lung fraction
