Predictors of hospitalization for COVID-19 in patients with autoimmune rheumatic diseases: results from a community cohort follow-up

Global Perspective on the Impact of the COVID-19 Pandemic on Rheumatology and Health Equity

Although the public health emergency associated with the COVID-19 pandemic has ended, challenges remain, especially for individuals with rheumatic diseases. We aimed to assess the historical and ongoing effects of COVID-19 on individuals with rheumatic diseases and rheumatology practices globally, with specific attention to vulnerable communities and lessons learned. We reviewed literature from several countries and regions, including Africa, Australia and New Zealand, China, Europe, Latin America, and the US. In this review, we summarize literature that not only examines the impact of the pandemic on individuals with rheumatic diseases, but also research that reports the lasting changes to rheumatology patient care and practice, and health service use. Across countries, challenges faced by individuals with rheumatic diseases during the pandemic included disruptions in health care and medication supply shortages. These challenges were associated with worse disease and mental health outcomes in some studies, particularly among those who had social vulnerabilities defined by socioeconomic, race, or rurality. Moreover, rheumatology practice was impacted in all regions, with the uptake of telemedicine and changes in health care utilization. While many regions developed rapid guidelines to disseminate scientific information, misinformation and disinformation remained widespread. Finally, vaccine uptake among individuals with rheumatic diseases has been uneven across the world. As the acute phase of the pandemic wanes, ongoing efforts are needed to improve health care access, stabilize rheumatology drug supplies, improve public health communication, and implement evidence-based vaccination practices to reduce COVID-19 morbidity and mortality among individuals with rheumatic diseases.

Prevalence and risk of COVID-19 in patients with rheumatic diseases: a systematic review and meta-analysis

Objectives

COVID-19 pandemic has already had a tremendous impact on the process of human society; the survival of mankind and the healthy living environment deterioration with the influence will last for many years. This meta-analysis aims to assess the risk of COVID-19 in patients with rheumatic diseases.

Methods

PubMed, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), and Chinese Biomedical Database (CBM) were systematically searched with no language restriction up to July 5, 2021. The pooled rates were synthesized by fixed effect model or random effect model depending on heterogeneity.

Results

A total of 83 articles were included in this meta-analysis. The incidence of COVID-19 in patient with rheumatic diseases was 0.0190 (95% CI: 0.0136-0.0252), and the hospitalization rate, intensive care unit admission rate, mechanical ventilation rate, and case fatality rate of patients with rheumatic diseases infected with COVID-19 were 0.4396 (95% CI: 0.3899-0.4898), 0.0635 (95% CI: 0.0453-0.0836), 0.0461 (95% CI: 0.0330-0.0609), and 0.0346 (95% CI: 0.0218-0.0493), respectively.

Conclusions

Our research shows that patients with rheumatic diseases have great risk of COVID-19. Differences in COVID-19 incidence, hospitalization rates, and mortality rates in regions were statistically significant. We still need to pay attention to the risk of COVID-19 in patients with rheumatic diseases.

Key Points

• Although the risk of COVID-19 in patients with rheumatic diseases has been discussed in previous meta-analysis, their research directions were inconsistent, and few studies focus on prevalence or serious outcomes of COVID-19 in patient with rheumatic diseases, while the quality of these articles was variable.

• The incidence of COVID-19 and serious clinical outcomes in patients with rheumatic diseases were still high along with differential risks in most regions.

• The use of glucocorticoids and conventional synthetic disease-modifying antirheumatic drugs did not affect the hospitalization rate and mortality in rheumatism patients with COVID-19.

Inactivated SARS-CoV-2 vaccine in primary Sjögren’s syndrome: humoral response, safety, and effects on disease activity

Introduction

There is no study specifically focused on SARS-CoV-2 vaccine in primary Sjögren’s syndrome (pSS).

Objectives

To assess the immunogenicity, safety, possible effects on disease activity, and autoantibody profile of the Sinovac-CoronaVac vaccine in pSS.

Methods

Fifty-one pSS patients and 102 sex- and age-balanced controls without autoimmune diseases were included in a prospective phase 4 trial of the Sinovac-CoronaVac vaccine (two doses 28 days apart, D0/D28). Participants were assessed in three face-to-face visits (D0/D28 and six weeks after the 2nd dose (D69)) regarding adverse effects; clinical EULAR Sjögren’s Syndrome Disease Activity Index (clinESSDAI); anti-SARS-CoV-2 S1/S2 IgG (seroconversion (SC) and geometric mean titers (GMT)); neutralizing antibodies (NAb); and pSS autoantibody profile.

Results

Patients and controls had comparable female sex frequency (98.0% vs. 98.0%, p = 1.000) and mean age (53.5 ± 11.7 vs. 53.4 ± 11.4 years, p = 0.924), respectively. On D69, pSS patients presented moderate SC (67.5% vs. 93.0%, p < 0.001) and GMT (22.5 (95% CI 14.6–34.5) vs. 59.6 (95% CI 51.1–69.4) AU/mL, p < 0.001) of anti-SARS-CoV-2 S1/S2 IgG but lower than controls, and also, moderate NAb frequency (52.5% vs. 73.3%, p = 0.021) but lower than controls. Median neutralizing activity on D69 was comparable in pSS (58.6% (IQR 43.7–63.6)) and controls (64% (IQR 46.4–81.1)) (p = 0.219). Adverse events were mild. clinESSDAI and anti-Ro(SS-A)/anti-La(SS-B) levels were stable throughout the study (p > 0.05).

Conclusion

Sinovac-CoronaVac vaccine is safe in pSS, without a deleterious impact on disease activity, and has a moderate short-term humoral response, though lower than controls. Thus, a booster dose needs to be studied in these patients.

Trial registration

ClinicalTrials.gov Identifier: NCT04754698.

Key Points • Sinovac-CoronaVac vaccine is safe in pSS, without a detrimental effect on systemic disease activity, and has a moderate short-term humoral response • A booster doseshould be considered in these patients
