RESUMO
Covid-19 disease is implicated in increased mortality among immunocompromised patients. The JAK inhibitor, baricitinib (bar), or the IL-6 inhibitor, tocilizumab (toc), demonstrated a survival benefit in patients with severe disease.However, evidence supporting their use in immunocompromised patients with severe Covid-19 is scarce.We aimed to assess clinical outcomes of bar/toc treatment in immunocompromised patients. A multi-center registry of consecutive immunocompromised patients hospitalized due to severe Covid-19 during the Omicron variant dominance period. After excluding patients who did not require high oxygen supply, patients treated with bar/toc were compared to patients treated by standard of care (SOC). Primary outcome was in hospital mortality. Secondary outcomes were 30 and 60 day mortality, super-infection and thromboembolic events. Among an overall 228 immunocompromised patients hospitalized in six Israeli hospitals with severe Covid-19, 112 patients required high oxygen support, of whom 48 (43%) were treated with bar/toc. In-hospital mortality rates were exceptionally high and did not significantly differ between bar/toc and SOC treated patients (62.5% vs. 64.1%, p = 1.0). A logistic regression analysis revealed that advanced age and incomplete vaccination were predictors of in-hospital mortality. Patients treated with bar/toc had no excess of suspected super-infection (62.8% vs. 60.7%, p = 0.84) or thromboembolic events (8.3% vs 3.1%, p = 0.39). In immunocompromised patients with severe Covid-19 and a high oxygen demand, bar/toc therapy was not associated with reduced mortality or with a higher rate of associated complications, compared to SOC. Larger prospective studies should better address efficacy and safety.

Background: Early reports described an increased risk of herpes zoster following receipt of mRNA-based COVID-19 vaccines. The objective was to assess whether COVID-19 vaccine is associated with varicella-zoster virus-induced neurologic disease (VZV-ND). Methods: This multicenter retrospective case-control study with a test-negative design was conducted at 12 hospitals in Israel. We included all patients admitted with VZV-ND between January 2020 and December 2021 and matched controls with a negative polymerase chain reaction result for VZV in cerebrospinal fluid. Results: We identified 188 patients meeting the case definition of VZV-ND who were admitted during the study period. Cases were matched with 376 controls. There was no significant variation in the incidence of VZV-ND between 1 year preceding and 1 year following the deployment of BNT162b2 in Israel. Analysis of persons who had received at least 1 dose of COVID-19 vaccine (n = 259) showed similar proportions of VZV-ND and non-VZV-ND in 4 intervals (30, 42, 50, 60 days) following the last vaccine dose. The median time from the last vaccine dose to hospitalization with a neurologic syndrome was 53 days (IQR, 25-128) and 82 days (IQR, 36-132) for VZV-ND and non-VZV-ND, respectively, not reaching statistical significance (P = .056). The rate of VZV-ND in vaccinated patients was no different from the rate in the unvaccinated group (30.9% vs 35.4%, P = .2). Conclusions: We did not find an association between COVID-19 vaccine and VZV-ND. Since COVID-19 vaccine is now recommended yearly, every fall and winter, establishing the safety of the vaccine is of great importance.
