Incidence Prevalence

Background:Rheumatoid arthritis (RA) predominantly affects women and has a significant impact on childbearing. Several population-based studies identifying incidence, prevalence, and medication use of RA have been reported, yet epidemiological studies focusing on women with RA in childbearing years are missing.Objectives:We aimed to identify the incidence, prevalence and medication use of RA among Korean women in childbearing years.Methods:From National Health Insurance Service (NHIS) data (2009-2016), containing inpatient and outpatient claim information for approximately 97% of the Korean population, we identified 9,217,139 women aged between 20-44 years. Incidence and prevalence of RA in the specific sociodemographic group of women in childbearing age were analyzed, and the prevalence of medication prescription were compared between women with RA and controls without rheumatic diseases such as RA, systemic lupus erythematosus, and ankylosing spondylitis. Individuals with RA were defined by the presence of International Classification of Disease, 10th revision code, M05. The medication use was defined as receiving > 90days prescriptions of NSAIDs, corticosteroids (CSs), and conventional synthetic (cs) disease modifying antirheumatic drugs (DMARDs) or > 1day prescription of biologic (b) DMARDs.Results:Total 24,590 women with RA were identified. The average incidence of RA during 2011-2016 among women in childbearing years was 24.1/100,000 person-years (PYs) (95% CI 20.91-27.31) with a yearly increase from 20.99/100,000 PYs in 2011 to 28.38/100,000 PYs in 2016. The average prevalence of RA during 2009-2016 among women in childbearing years was 105.2/100,000 PYs (95% CI 99.0-111.5) with a minimum of 95.7/100,000 PYs in 2009 and a maximum of 110.5/100,000 PYs in 2016. There were increasing trends in both incidence and prevalence of RA according to age among women in childbearing years peaking in the age group of 40-44 years. The prescriptions of NSAIDs, CSs, csDMARDs and bDMARDs were more frequent in women with RA than controls (NSAIDs; 94.21% vs 21.79%, CSs; 83.65% vs 4.28%, csDMARDs; 91.23% vs 0.41%, bDMARDs; 0.11% vs 0%, p<0.001).Conclusion:The incidence and prevalence of RA are high among Korean women in childbearing years, and medication use was significantly more frequent in this specific population than controls. High disease burden is imposed upon women in childbearing years.References:[1] Won S, Cho SK, Kim D, Han M, Lee J, Jang EJ, Sung YK, Bae SC: Update on the prevalence and incidence of rheumatoid arthritis in Korea and an analysis of medical care and drug utilization.

Disease Modifying

Introduction: The coronavirus disease (COVID-19) became a global pandemic in 2019. Some studies have shown that the virus can cause a higher mortality in people with weakened immune systems, such as the elderly, those taking immunosuppressive drugs, and those with underlying disorders, than in the general population. Objectives: The aim of this study was to evaluate the prevalence of COVID-19 in patients with rheumatic disorders who received biologic disease-modifying antirheumatic drugs (DMARDs). The effect of precautionary self-isolation in these patients was also determined. Patients and Methods: This descriptive study involved 200 patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and multiple sclerosis (MS) who were treated with biologic DMARDs. Patients with symptoms of the coronavirus infection were invited to have a COVID-19 test that involved a COVID-19 IgG antibody test or a polymerase chain reaction (PCR) test (i.e., nasal swab). Additionally, patients were asked about their precautionary self-isolation status during this period. Results: The mean age of the patients was 51.29 years ± 13.38 years. The ratio of males to females was 27 to 173. Of the 200 patients included in the study, 156 (78%) had RA, 10 (5%) had SLE, and 34 (17%) had MS. Seventy-five percent of the patients used rituximab. Ten patients (5%) were symptomatic of COVID-19, although only four patients had a definitive diagnosis of the disease. All patients who were symptomatic of COVID-19 took rituximab. Ten percent of patients who did not observe the precautionary self-isolation period were diagnosed with COVID-19. Conclusion: Patients who receive biologic DMARDs have a lower risk of developing COVID-19 and a lower risk of mortality from the disease than the general population.
