Interferon-induced membrane proteins (IFITM) 3 gene variants are known risk factor for severe viral diseases. We examined whether IFITM3 variant may underlie the heterogeneous clinical outcomes of SARS-CoV-2 infection-induced COVID-19 in large Arab population. We genotyped 880 Saudi patients; 93.8% were PCR-confirmed SARS-CoV-2 infection, encompassing most COVID-19 phenotypes. Mortality at 90 days was 9.1%. IFITM3-SNP, rs12252-G allele was associated with hospital admission (OR = 1.65 [95% CI; 1.01-2.70], P = 0.04]) and mortality (OR = 2.2 [95% CI; 1.16-4.20], P = 0.01). Patients less than 60 years old had a lower survival probability if they harbor this allele (log-rank test P = 0.002). Plasma levels of IFNγ were significantly lower in a subset of patients with AG/GG genotypes than patients with AA genotype (P = 0.00016). Early identification of these individuals at higher risk of death may inform precision public health response.

Coronavirus (cov) disease 2019 pandemic caused by severe acute respiratory syndrome cov 2 has imposed significant demands on healthcare systems across the world. These demands were more significant on obstetrics and gynecology (obgyn) patients, who required services that had to continue despite the closure of other services. This paper describes the change management of an obgyn department at a tertiary health-care center. That experience resulted in a complete management shift in the institution and the formation of an infectious disease epidemic plan for respiratory infections. Description of the change management performed, difficulties encountered, and achievements obtained can assist other departments change management when they face similar situations.
