Prognostic improvement and treatment of COVID-19 in patients with rheumatic diseases until December 2022: Analysis of the JCR COVID-19 registry in Japan

OBJECTIVES

The aim is to evaluate the treatment and prognosis of coronavirus disease 2019 (COVID-19) according to the time of onset and dominant strain in patients with rheumatic diseases.

METHODS

This study analysed a nationwide COVID-19 registry of Japanese patients with rheumatic diseases compiled between June 2020 and December 2022. The primary endpoints of the study were hypoxaemia incidence and mortality. Multivariate logistic regression analysis was performed to assess differences according to the period of onset.

RESULTS

A total of 760 patients were compared across four periods. Hypoxaemia rates were 34.9, 27.2, 13.8, and 6.1% and mortality rates were 5.6, 3.5, 1.8, and 0% until June 2021, between July and December 2021, January and June 2022, and July and December 2022, respectively. History of vaccination (odds ratio, 0.39; 95% confidence interval, 0.18-0.84) and onset during the July to December 2022 Omicron BA.5-dominant period (odds ratio, 0.17; 95% confidence interval, 0.07-0.41) were negatively associated with hypoxaemia in the multivariate model, adjusting for age, sex, obesity, glucocorticoid dose, and comorbidities. Over the Omicron-dominant period, antiviral treatment was administered in 30.5% of patients with a low probability of hypoxaemia.

CONCLUSIONS

COVID-19 prognosis improved over time in patients with rheumatic diseases, especially in the Omicron BA.5-dominant period. In the future, treatment of mild cases should be optimised.

The Risk of COVID-19 and Its Outcomes in Korean Patients With Gout: A Multicenter, Retrospective, Observational Study

This retrospective cohort study aimed to compare coronavirus disease 2019 (COVID-19)-related clinical outcomes between patients with and without gout. Electronic health record-based data from two centers (Seoul National University Hospital [SNUH] and Boramae Medical Center [BMC]), from January 2021 to April 2022, were mapped to a common data model. Patients with and without gout were matched using a large-scale propensity-score algorithm based on population-level estimation methods. At the SNUH, the risk for COVID-19 diagnosis was not significantly different between patients with and without gout (hazard ratio [HR], 1.07; 95% confidence interval [CI], 0.59-1.84). Within 30 days after COVID-19 diagnosis, no significant difference was observed in terms of hospitalization (HR, 0.57; 95% CI, 0.03-3.90), severe outcomes (HR, 2.90; 95% CI, 0.54-13.71), or mortality (HR, 1.35; 95% CI, 0.06-16.24). Similar results were obtained from the BMC database, suggesting that gout does not increase the risk for COVID-19 diagnosis or severe outcomes.

Cardiovascular health worsening in patients with autoimmune rheumatological diseases during the COVID-19 pandemic

Rheumatic autoimmune diseases are associated with a myriad of comorbidities. Of particular importance due to their morbimortality are cardiovascular diseases. COVID-19 greatly impacted the world population in many different areas. Patients with rheumatic diseases had to face changes in their healthcare, in addition to unemployment, a decrease in physical activity, social isolation, and lack of access to certain medications. This review summarizes the impact of COVID-19 pandemic on cardiovascular risk factors, comorbidities, and unhealthy behaviors in patients with rheumatic inflammatory autoimmune diseases, particularly focused on rheumatoid arthritis and systemic lupus erythematosus. Searches were carried out in MEDLINE/PubMed and Scopus from August to December 2022. Four reviewers screened the title and abstract of retrieved records. Potentially eligible reports were then reviewed in full text. Differences were reconciled by either consensus or discussion with an external reviewer. During the COVID-19 pandemic, patients with rheumatic diseases showed an increase in the prevalence of mental health disorders (43.2-57.7%), reduced physical activity (56.8%), and a worsening in eating behaviors. Alcohol intake increased (18.2%), especially in early phases of the pandemic. Smoking prevalence decreased (28.2%). Dyslipidemia and hypertension showed no changes. The pandemic and lockdown affected rheumatic patients not only in disease-related characteristics but in the prevalence of their cardiovascular comorbidities and risk factors. Lifestyle changes, such as healthy eating, physical activity, and optimal management of their rheumatic diseases and comorbidities, are essential to manage the long-lasting consequences of the COVID-19 outbreak. Key Points • During the COVID-19 pandemic, anxiety, depression, sedentarism, obesity, and a worsening in eating behaviors increased. •Patients with rheumatic diseases and comorbidities have worse clinical outcomes and a higher cardiovascular disease burden than those without them. •Comparative studies are necessary to precisely elucidate the pandemic's impact on the prevalence of cardiovascular disease, risk factors, and comorbidities in patients with rheumatoid arthritis and systemic lupus erythematosus.

Temporal trends in COVID-19 outcomes among patients with systemic autoimmune rheumatic diseases: from the first wave through the initial Omicron wave

OBJECTIVES

To investigate temporal trends in incidence and severity of COVID-19 among patients with systemic autoimmune rheumatic diseases (SARDs) from the first wave through the initial Omicron wave.

METHODS

We conducted a retrospective cohort study investigating COVID-19 outcomes among patientswith SARD systematically identified to have confirmed COVID-19 from 1 March 2020 to 31 January 2022 at Mass General Brigham. We tabulated COVID-19 counts of total and severe cases (hospitalisations or deaths) and compared the proportion with severe COVID-19 by calendar period and by vaccination status. We used logistic regression to estimate the ORs for severe COVID-19 for each period compared with the early COVID-19 period (reference group).

RESULTS

We identified 1449 patients with SARD with COVID-19 (mean age 58.4 years, 75.2% female, 33.9% rheumatoid arthritis). There were 399 (28%) cases of severe COVID-19. The proportion of severe COVID-19 outcomes declined over calendar time (p for trend <0.001); 46% of cases were severe in the early COVID-19 period (1 March 2020-30 June 2020) vs 15% in the initial Omicron wave (17 December 2021-31 January 2022; adjusted OR 0.29, 95% CI 0.19 to 0.43). A higher proportion of those unvaccinated were severe compared with not severe cases (78% vs 60%).

CONCLUSIONS

The proportion of patients with SARD with severe COVID-19 has diminished since early in the pandemic, particularly during the most recent time periods, including the initial Omicron wave. Advances in prevention, diagnosis and treatment of COVID-19 may have improved outcomes among patients with SARD.

Temporal trends in COVID-19 outcomes among patients with systemic autoimmune rheumatic diseases: From the first wave to Omicron

Objectives

To investigate temporal trends in incidence and severity of COVID-19 among patients with systemic autoimmune rheumatic diseases (SARDs) from the first wave through the Omicron wave.

Methods

We conducted a retrospective cohort study investigating COVID-19 outcomes among SARD patients systematically identified to have confirmed COVID-19 from March 1, 2020 to January 31, 2022 at a large healthcare system in Massachusetts. We tabulated COVID-19 counts of total and severe cases (hospitalizations or deaths) and compared the proportion with severe COVID-19 by calendar period and by vaccination status. We used logistic regression to estimate the ORs for severe COVID-19 for each period compared to the early COVID-19 period (reference group).

Results

We identified 1449 SARD patients with COVID-19 (mean age 58.4 years, 75.2% female, 33.9% rheumatoid arthritis). There were 399 (27.5%) cases of severe COVID-19. The proportion of severe COVID-19 outcomes declined over calendar time (p for trend <0.001); 45.6% of cases were severe in the early COVID-19 period (March 1-June 30, 2020) vs. 14.7% in the Omicron wave (December 17, 2021-January 31, 2022; adjusted odds ratio 0.29, 95%CI 0.19-0.43). A higher proportion of those unvaccinated were severe compared to not severe cases (78.4% vs. 59.5%).

Conclusions

The proportion of SARD patients with severe COVID-19 has diminished since early in the pandemic, particularly during the most recent time periods, including the Omicron wave. Advances in prevention, diagnosis, and treatment of COVID-19 may have improved outcomes among SARD patients.

KEY MESSAGES

What is already known about this subject?: Patients with systemic autoimmune rheumatic diseases (SARDs) may be at increased risk for severe COVID-19, defined as hospitalization or death.Previous studies of SARD patients suggested improving COVID-19 outcomes over calendar time, but most were performed prior to the wide availability of COVID-19 vaccines or the Omicron wave that was characterized by high infectivity.What does this study add?: The proportion of SARD patients with severe COVID-19 outcomes was lower over calendar timeThe adjusted odds ratio of severe COVID-19 in the Omicron wave was 0.29 (95%CI 0.19-0.43) compared to early COVID-19 period.The absolute number of severe COVID-19 cases during the peak of the Omicron variant wave was similar to the peaks of other waves.SARD patients with severe vs. not severe COVID-19 were more likely to be unvaccinated.How might this impact on clinical practice or future developments?: These findings suggest that advances in COVID-19 prevention, diagnosis, and treatment have contributed to improved outcomes among SARD patients over calendar time.Future studies should extend findings into future viral variants and consider the roles of waning immunity after vaccination or natural infection among SARD patients who may still be vulnerable to severe COVID-19.

COVID-19 in Patients with Psoriatic Arthritis

The COVID-19 pandemic has a negative impact on all aspects of human life and can lead to the exacerbation of chronic diseases. At the same time, it is known that a higher risk of infection and a more severe course of coronavirus infection is found in the elderly, as well as in people with serious comorbidities. Psoriatic arthritis (PsA) is a type of inflammatory arthritis that is often diagnosed in patients with psoriasis. Specific treatment of patients with chronic inflammatory joint disease include nonsteroidal anti-inflammatory drugs, glucocorticosteroids, disease-modifying antirheumatic drugs, new biological agents, including monoclonal antibodies to IL-6, IL-1, TNF-a, target disease modifying drugs. Medications used for PsA treatment can potentially have both negative and positive effects on the course of COVID-19. The objective: to analyze the features of COVID-19 in patients with PsA and to study the comorbid pathology after coronavirus infection. Materials and methods. The study involved 174 people with a verified diagnosis of PsA. Patients were divided into two groups. Group I included 112 (64.4%) persons who had COVID-19, and group II - 62 (35.6%) who had not had coronavirus infection at the time of first examination. Patients in group I significantly differed from group II in age (p <0.001) and duration of PsA (p <0.001), showed a significantly higher degree of psoriatic skin lesions and activity of the underlying disease (p = 0.001) compared to patients from group II. The participants of the study underwent examination characterize the course of the psoriatic disease and skin lesions and risk of cardiovascular disease. Results. To date, there are no clear scientific data that reveal the specific features of COVID-19 infection and the effect of antirheumatic therapy on the development of dangerous complications associated with coronavirus infection in patients with PsA. The analysis of comorbid pathology has found cardiovascular pathology in 67 (59.8%) of patients, including arterial hypertension – in 58 (51.8%) people, metabolic syndrome – in 34 (30.4%), diseases of the digestive system – in 32 (28.6%) and respiratory system – in 24 (21.4%) of persons. Conclusions. Patients with higher activity and duration of the PsA were significantly more likely to get COVID-19 and demonstrated higher total cardiovascular risk for the next 10 years. Further research is needed to study the impact of specific basic rheumatological drugs on the outcomes of COVID-19 and to analyze the broader effects of the pandemic on the course of psoriatic arthritis.
