COVID-19 outcomes in patients with and without autoimmune rheumatic diseases: A multicenter comparative study.

Background And Objective: People with rheumatic diseases are particularly concerned with the coronavirus disease 2019 (COVID-19) pandemic. Our work aimed to study the impact of pre-existing autoimmune rheumatic disease (AIRD) and its immunosuppressive drugs on COVID-19 severity and outcome.

Patients And Methods: This is a multicenter case-control study performed between September 2020 and February 2021 on 130 adults with COVID-19, including 66 patients with AIRD and 64 without AIRD, who served as a control group.

Predictive value of serum uric acid in hospitalized adolescents and adults with acute asthma.

Background: High serum uric acid (sUA) is an indicator of oxidative stress and is linked to tissue hypoxia in asthma. The objective of this case series was to investigate the prognostic role of sUA in patients with acute asthma exacerbations and the link between sUA and spirometric lung tests.

Patients And Methods: This cross-sectional observational study included 120 patients with acute asthma exacerbations and 120 controls, categorized according to peak expiratory flow rate into moderate, and severe and life-threatening asthma.
