Background And Aims: Few reports, all retrospective, have evaluated vaccine coverage against COVID-19 infection in cirrhotic subjects. No data are available for European Countries. We aimed to explore this topic and potential independent predictors of lack of vaccination.
Methods: Between January 1st and June 30th 2022, 1512 cirrhotic subjects of any etiology were consecutively enrolled in an observational - prospective study in 8 referral centers in Italy. Adjusted Odds Ratios (O.R.) for the association with lack of vaccination and with occurrence of breakthrough infection were evaluated by multiple logistic regression analysis.
Results: Overall vaccine coverage was 89.7% (80% among people born abroad). Among the 1358 vaccinated people, 178 (13.1%) had a breakthrough infection; of them 12 (6.7%) were hospitalized, but none died. Independent predictors associated with lack of vaccination were birth abroad, age <65 years and lower years of schooling. Child stage B/C was the only independent predictor of breakthrough infection. Occurrence of breakthrough infection was more likely reported in subjects who received 2 doses of vaccine than in those who received 3 doses (33.9% versus 9.0%; P<0.001).
Conclusion: High vaccine coverage against COVID-19 infection is observed among cirrhotic subjects in Italy. Vaccine is effective in preventing severe outcomes. Three doses are more effective than two, even in cirrhotic subjects.
Lay Summary: This large cohort study evidenced high vaccine coverage against COVID-19 infection among cirrhotic subjects in a European country and the effectiveness of vaccine in preventing severe outcomes. Three doses of vaccine are more effective than two in preventing breakthrough infection and hospitalization. Informative campaigns targeting people younger than 65 years of age and those with lower years of schooling may increase these excellent results.

Background: Pediatric patients with autoimmune and inflammatory diseases often require immunosuppressive therapy, which increases their susceptibility to infections, including varicella-zoster virus (VZV). While the live attenuated varicella vaccine is contraindicated in most immunocompromised children, the recombinant subunit vaccine, Shingrix, may offer an alternative preventive strategy. However, data on its safety, immunogenicity, and efficacy in pediatric VZV-naïve patients remain limited.

Understanding factors contributing to anticipatory breadth, wherein affinity maturation against an ancestral strain yields neutralization capacity against evolved variants, is therefore of great importance. Here, we investigated the mechanism of anticipatory breadth development in a public antibody family targeting the functionally restricted ACE2 binding site on SARS-CoV-2.

Adult T-cell leukemia/lymphoma (ATL) is a T-cell malignancy caused by human T-cell leukemia virus type I (HTLV-1). Treatment strategies have been established by classification of ATL as aggressive (acute, lymphoma, and chronic ATL with any unfavorable prognostic factors) or indolent (smoldering and chronic ATL without any unfavorable prognostic factors). The standard of care (SOC) for aggressive ATL has been dose-intensified multi-agent chemotherapy.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare clonal disorder characterized by complement-mediated hemolysis, thrombosis, and bone marrow failure. Eculizumab (Ecu), a C5 inhibitor, blocks intravascular hemolysis (IVH) and improves prognosis. Ravulizumab and crovalimab have longer half-lives, and reduce treatment burden.

Background: Immune induction under B-cell depletion is complex and far from being fully understood.
Methods: We investigated clinical and immunological responses after dual homologous mRNA vaccination with BNT162b2 and after booster vaccination or infection in 14 B-cell depleted patients with inflammatory central nervous system disease in comparison to 28 healthy controls. Spike-specific IgG were determined using ELISA and neutralizing activity by surrogate assay.
