Seroprevalence of hepatitis E virus (HEV) infection in blood donors and renal transplant recipients: a retrospective study from central Italy [Sieroprevalenza dell’infezione da virus dell’epatite E (HEV) in donatori di sangue e pazienti trapiantati di rene: Uno studio retrospettivo dal centro Italia]

Autochthonous hepatitis E virus (HEV) is an emerging health issue in developed countries and is thought to be a porcine zoonosis; its spread is underestimated and there is concern about the possibility of chronic infection in immunosuppressed patients; HEV transmission through blood has also been demonstrated. We conducted a retrospective study (2007-2013) on HEV seroprevalence using stored serum samples from 132 blood donors and 118 renal transplant recipients living mainly in central Italy. Anti-HEV IgG was positive in 12/132 (9.1%) of the blood donors and 12/118 (10.2%) of the transplant recipients. All subjects but one were autochthonous and none showed signs of liver disease at the time of sampling. A significant association was documented between mean age of patients and the serology against HEV especially in the group of blood donors. Our study, albeit limited and retrospective, confirms the circulation of autochthonous HEV in central Italy; the presence of antibodies against HEV in particular categories of persons such as blood donors and transplant patients, who are not screened for the infection, raises questions in terms of transfusion safety and health protection of immunocompromised patients

Tocilizumab for patients with COVID-19 pneumonia. The single-arm TOCIVID-19 prospective trial

BackgroundTocilizumab blocks pro-inflammatory activity of interleukin-6 (IL-6), involved in pathogenesis of pneumonia the most frequent cause of death in COVID-19 patients.MethodsA multicenter, single-arm, hypothesis-driven trial was planned, according to a phase 2 design, to study the effect of tocilizumab on lethality rates at 14 and 30 days (co-primary endpoints, a priori expected rates being 20 and 35%, respectively). A further prospective cohort of patients, consecutively enrolled after the first cohort was accomplished, was used as a secondary validation dataset. The two cohorts were evaluated jointly in an exploratory multivariable logistic regression model to assess prognostic variables on survival.ResultsIn the primary intention-to-treat (ITT) phase 2 population, 180/301 (59.8%) subjects received tocilizumab, and 67 deaths were observed overall. Lethality rates were equal to 18.4% (97.5% CI: 13.6-24.0, P=0.52) and 22.4% (97.5% CI: 17.2-28.3, P<0.001) at 14 and 30 days, respectively. Lethality rates were lower in the validation dataset, that included 920 patients. No signal of specific drug toxicity was reported. In the exploratory multivariable logistic regression analysis, older age and lower PaO2/FiO2 ratio negatively affected survival, while the concurrent use of steroids was associated with greater survival. A statistically significant interaction was found between tocilizumab and respiratory support, suggesting that tocilizumab might be more effective in patients not requiring mechanical respiratory support at baseline.ConclusionsTocilizumab reduced lethality rate at 30 days compared with null hypothesis, without significant toxicity. Possibly, this effect could be limited to patients not requiring mechanical respiratory support at baseline.Registration EudraCT (2020-001110-38); clinicaltrials.gov (NCT04317092)
