Abstract Introduction/objectives The objective of this study is to describe the treatment patterns and use of healthcare resources in a cohort of Colombian patients with rheumatoid arthritis (RA) treated with biological disease-modifying antirheumatic drugs (bDMARDs) or tofacitinib. Method This is a descriptive study from a retrospective cohort of patients diagnosed with RA who were treated with bDMARDs or tofacitinib after failure of conventional DMARDs (cDMARDs) or first bDMARD. Patients who were receiving pharmacological treatment between 01 January 2014 and 30 June 2018 were included. The analysis is through the revision of claim database and electronical medical records. Demographic and clinical data were collected. The costs of healthcare resources were estimated from the billing expense of healthcare service provider. Results We evaluated 588 RA patients on treatment with bDMARDs (n = 505) or tofacitinib (n = 83), most of them were in combination with cDMARDs (85.4%). The 88.1% were females and mean age was 57.3 ± 12.5 years. The median evolution of RA since diagnosis was 9 years (IQR:4–17.2). The mean duration of use during follow-up of the bDMARDs or tofacitinib was similar, with a mean of 9.8 ± 1.9 months. It was identified that 394 (67.0%) discontinued therapy. The average annual direct cost of care per patient was USD 8997 ± 2172, where 97.2% was due to drug costs. The average annual cost of treatment per patient with bDMARDs was USD 8604 and tofacitinib was USD 6377. Conclusions In the face of a first failure of cDMARD, bDMARDs are frequently added. A high frequency of patients do not persist treatment during the first year of follow-up. The pharmacological treatment is the most representative cause of healthcare costs. Key Points• Rheumatoid arthritis is a disease with a high burden of comorbidities, complications, and worse health-related quality of life and is associated with elevated healthcare costs.• The biological disease-modifying antirheumatic drugs or tofacitinib medications are indicated for those with significant progression of the disease and when there is a need for alternatives to achieve low levels of activity and remission.• Patients with rheumatoid arthritis treated with biological disease-modifying antirheumatic drugs or tofacitinib represent a significant economic burden to the health system, especially in the costs derived from pharmacological treatment.

To assess the prevalence and association of anti-cyclic citrullinated peptides and rheumatoid factor in Saudi rheumatoid arthritis patients.Over three years (February 2011 - February 2014). Demographic and clinical features, drugs, rheumatoid factor-positivity, and anti-cyclic citrullinated peptides-positivity were recorded for 205 Saudi rheumatoid arthritis patients (185 females; mean age was 45 years and mean disease duration was 5 years). Anti-cyclic citrullinated peptides and rheumatoid factor were assessed in serum. Disease activity scores for 28 joints was used. There were 36% rheumatoid factor+ve and 45% anti-cyclic citrullinated peptides+ve. 21.5% of the rheumatoid factor-ve subjects were anti-cyclic citrullinated peptides+ve. 13.3% of the rheumatoid factor positive patients were anti-cyclic citrullinated peptides-ve and 86.7% were anti-cyclic citrullinated peptides+ve. Significant association (P < 0.05) of anti-cyclic citrullinated peptides-positivity and rheumatoid factor-positivity with each other, and with gender, use of disease–modifying antirheumatic drugs, hydroxychloroquine and methotrexate. No direct impact of anti-cyclic citrullinated peptides status on the disease activity scores for 28 joints or its constituents (P > 0.5); nevertheless, anti-cyclic citrullinated peptides positive patients appear to represent a greater need for combination disease modifying drugs.

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.
