ABSTRACT

Összefoglaló. Az új típusú koronavírus (SARS-CoV-2) okozta pandémia súlyos terhet és nagy kihívást jelent a fertozésekkel szemben általában is fogékony, szerteágazó immunológiai és genetikai hátteru, primer immundeficiens (PID-) betegek számára. Az eddigi megfigyelések arra utalnak, hogy a SARS-CoV-2-fertozés és a súlyos COVID-19 mortalitása nem elsosorban az immunológiai alapbetegséggel, hanem sokkal inkább egyéb, a PID talaján megelozoen kialakult (például bronchiectasia, asthma, autoimmun betegség stb.) vagy attól független krónikus társbetegséggel (például diabetes, krónikus szív- és érrendszeri vagy vesebetegség) és szervi károsodással függ össze. A betegek egy kis csoportjában az I. típusú interferon-immunitás zavarát okozhatják génmutációk vagy autoantitestek termelése. A közleményben az eddig közölt adatok alapján beszámolunk a SARS-CoV-2-fertozés és a COVID-19 lefolyásáról és mortalitásáról PID-betegekben. Orv Hetil. 2022; 163(5): 166-170. Summary. The pandemic caused by the novel coronavirus (SARS-CoV-2) has resulted in tremendous challenges to the management of patients with primary immunodeficiencies (PIDs) representing a wide range of immunological and genetic entities. Preliminary data suggest that patients with PID would be at increased risk of severe disease and mortality from this newly emerged coronavirus. However, morbidity and mortality by SARS-CoV-2 may depend only partly on specific defect of immunity. Most of disease morbidity and mortality has been published to be related to previous damage of organs and tissues that had developed on the bases of PID before contracting SARS-CoV-2 or other, PID-independent disorders. In a small fraction of patients, impaired type I interferon immunity was found to predispose PID patients to severe coronavirus disease. In this review, we provide an update on published data about SARS-CoV-2 infections and COVID-19 in various PIDs. Orv Hetil. 2022; 163(5): 166-170.

ABSTRACT

At the start of the pandemic caused by the novel coronavirus (SARS-CoV-2), the Gaucher disease community anticipated that infection with this emerging viral pathogen would be associated with high morbidity and mortality in individuals with this chronic metabolic disorder. Surprisingly, however, preliminary studies suggest that Gaucher disease does not confer a higher risk of severe, life-threatening effects of SARS-CoV-2 infection, and no severe cases have been reported in large cohorts of patients from the United States, Europe and Israel. It is thought that the accumulation of glucocerebroside in the cells of Gaucher patients may promote immune tolerance rather than inflammation on exposure to SARS-CoV-2. We review here the current concepts of Gaucher disease and SARS-CoV-2 infection, focusing particularly on general prevention and vaccination. We also discuss the susceptibility to COVID-19 of patients with inborn errors of type 1 interferon (IFNα and IFNω) immunity. Orv Hetil. 2021; 162(24): 938-942.
