Insights
Connective tissue disease (CTD) patients experienced more severe COVID-19 outcomes compared to gout and ankylosing spondylitis (AS) patients. Hydroxychloroquine and glucocorticoids may reduce COVID-19 severity in rheumatic patients.
Area of Science:
- Rheumatology
- Infectious Diseases
- COVID-19 Research
Background:
- Rheumatic disease patients on immunosuppressants face higher infection risks.
- Specific risks for COVID-19 within rheumatic disease subtypes remain unclear.
Purpose of the Study:
- To investigate COVID-19 severity and outcomes in different rheumatic disease subcategories.
- To identify risk factors and protective treatments for COVID-19 in rheumatic patients.
Main Methods:
- Retrospective analysis of 100 rheumatic patients from 18,786 hospitalized COVID-19 patients.
- Data collected included demographics, medical history, disease severity, lab tests, and treatments.
- Comparison of outcomes between connective tissue disease (CTD), gout, and ankylosing spondylitis (AS) patients.
Main Results:
- Connective tissue disease (CTD) patients showed a trend towards more severe COVID-19 compared to gout and AS patients (p=0.081).
- CTD patients exhibited lower lymphocyte counts, hemoglobin, and platelet counts.
- Hydroxychloroquine and low-to-medium dose glucocorticoids before diagnosis were associated with reduced progression to severe/critical COVID-19 (p=0.001 and p=0.006, respectively).
Conclusions:
- COVID-19 may present more severely in connective tissue disease (CTD) patients compared to those with ankylosing spondylitis (AS) or gout.
- Hydroxychloroquine and glucocorticoid therapy may mitigate severe COVID-19 progression in rheumatic patients.
Abstract:
Novel Coronavirus disease 2019 (COVID-19) has spread rapidly around the world. Individuals with immune dysregulation and/or on immunosuppressive therapy, such as rheumatic patients, are considered at greater risk for infections. However, the risks of patients with each subcategory of rheumatic diseases have not been reported. Here, we identified 100 rheumatic patients from 18,786 COVID-19 patients hospitalized in 23 centers affiliated to Hubei COVID-19 Rheumatology Alliance between January 1 and April 1, 2020. Demographic information, medical history, length of hospital stay, classification of disease severity, symptoms and signs, laboratory tests, disease outcome, computed tomography, and treatments information were collected. Compared to gout and ankylosing spondylitis (AS) patients, patients with connective tissue disease (CTD) tend to be more severe after COVID-19 infection (p = 0.081). CTD patients also had lower lymphocyte counts, hemoglobin, and platelet counts (p values were 0.033, < 0.001, and 0.071, respectively). Hydroxychloroquine therapy and low- to medium-dose glucocorticoids before COVID-19 diagnosis reduced the progression of COVID-19 to severe/critical conditions (p = 0.001 for hydroxychloroquine; p = 0.006 for glucocorticoids). Our data suggests that COVID-19 in CTD patients may be more severe compared to patients with AS or gout.
