THU0086 The Survival Impact of Statins in Rheumatoid Arthritis: A General Population-Based Cohort Study

ObjectiveMortality trends of rheumatoid arthritis (RA) are largely unknown over the past decade when new drugs and management strategies have been adopted to effectively treat RA.MethodsUsing The Health Improvement Network, an electronic medical record database representative of the UK general population, we identified patients with incident RA and up to five individuals without RA matched for age, sex and year of diagnosis between 1999 and 2014. The RA cohort was divided in two sub-cohorts based on the year of RA diagnosis: the early cohort (1999–2006) and the late cohort (2007–2014). We compared mortality rates, HRs (using a Cox proportional hazard model) and rate differences (using an additive hazard model) between RA and non-RA cohorts adjusting for potential confounders.ResultsPatients with RA diagnosed between 1999 and 2006 had a considerably higher mortality rate than their comparison cohort (ie, 29.1 vs 18.0 deaths/1000 person-years), as compared with a moderate difference in patients with RA diagnosed between 2007 and 2014 and their comparison cohort (17.0 vs 12.9 deaths/1000 years). The corresponding absolute mortality rate differences were 9.5 deaths/1000 person-years (95% CIs 7.5 to 11.6) and 3.1 deaths/1000 person-years (95% CI 1.5 to 4.6) and the mortality HRs were 1.56 (95% CI 1.44 to 1.69) and 1.29 (95% CI 1.17 to 1.42), respectively (both p values for interaction <0.01).ConclusionThis general population-based cohort study indicates that the survival of patients with RA has improved over the past decade to a greater degree than in the general population. Improved management of RA and its associated comorbidities over recent years may be providing a survival benefit.

BackgroundRecent hospital-based studies have suggested a sixfold increased risk of pulmonary embolism (PE) in rheumatoid arthritis (RA) in the year following admission. We evaluated the risk of PE and deep vein thrombosis (DVT) and associated time trend among RA patients (84.5% without a history of hospitalisation during the past year) derived from the general population.MethodsWe conducted a cohort study using an electronic medical records database representative of the UK general population, collected from 1986 to 2010. Primary definitions of the RA cohort (exposure) and PE/DVT outcomes required physician diagnoses followed by corresponding treatments. We estimated relative risks (RRs) of PE and DVT compared with a matched non-RA comparison cohort, adjusting for age, sex, smoking, body mass index, comorbidities and hospitalisations.ResultsAmong 9589 individuals with RA (69% female, mean age of 58 years), 82 developed PE and 110 developed DVT (incidence rates, 1.5 and 2.1 per 1000 person-years). Compared with non-RA individuals (N=95 776), the age-, sex- and entry-time-matched RRs were 2.23 (95% CI 1.75 to 2.86) for PE and 2.20 (CI 1.78 to 2.71) for DVT. Adjusting for other covariates, the corresponding RRs were 2.16 (CI 1.68 to 2.79) and 2.16 (CI 1.74 to 2.69). The time-specific RRs for PE were 3.27, 1.88 and 2.35 for follow-up times of <1 year, 1–4.9 years, and ≥5 years, and corresponding RRs for DVT were 3.16, 1.82 and 2.32.ConclusionsThis population-based study indicates an increased risk of PE and DVT in RA, supporting increased monitoring of venous-thromboembolic complications and risk factors in RA, regardless of hospitalisation.

Background and Objectives: Mortality rates among patients with rheumatoid arthritis (RA) have been reported to be higher than in the general population. The long-term prognosis of RA has improved in recent years due to early diagnosis, as well as effective pharmacological treatment, and this may be able to diminish the excess mortality risk. This study was designed to investigate mortality (a) in patients with RA in a retrospectively defined national RA cohort in comparison with the general Lithuanian population, and (b) to conduct a systematic review of the literature from different countries and meta-analysis. Materials and Methods: In this national retrospective cohort study, patients with a first-time diagnosis of RA in the period between 1 January 2013 and 31 December 2017 were identified from the Lithuanian Compulsory Health Insurance Information System database SVEIDRA. All cases were cross-checked with the Health Information Center at the Institute of Hygiene, for the vital status of these patients and date of death if documented. The standardized mortality ratios (SMRs) with 95% confidence intervals (CI) obtained for all-cause mortality in patients with RA adjusted for age, sex, and calendar year were calculated. The search for published studies using the combination of keywords “rheumatoid arthritis AND standardized mortality ratio” was performed in MEDLINE (via PubMed, OVID, and EBSCO), Science Direct, Taylor & Francis, and Springer databases. Studies were selected according to described inclusion and exclusion criteria listed in the paper, and a meta-analysis was conducted. A random-effect meta-analysis model was used to compute the pooled standardized mortality ratios (meta-SMRs). Results: Overall, 4623 patients with newly diagnosed RA during the 2013–2017 period were identified and enrolled in the Lithuanian population-based cohort. The mean age of patients at the time of RA diagnosis was 58.7 (standard deviation (SD) 15.1) years, and 77.1% of the patients were women. The estimated SMR for all-cause mortality was 1.15 (95% CI 1.02, 1.29). The SMR for men (SMR 1.14, 95% CI 0.94, 1.39) was higher than for women (SMR 1.03, 95% CI 0.89, 1.19). A systematic literature search revealed 12 studies meeting the inclusion criteria, starting from 2010 to 2020, representing 50,072 patients. The meta-SMR in patients with RA for all-cause mortality was 1.41 (95% CI 1.29, 1.55). All-cause mortality risk was higher for men (meta-SMR 1.53, 95% CI 1.31, 1.78) than for women (meta-SMR 1.46, 95% CI 1.2, 1.77). Conclusions: In a retrospectively defined population-based national RA cohort, a 15% excess risk of death was observed among patients with RA compared to the general Lithuanian population. Patients with RA have a higher mortality risk than the general population. Published data indicate that the risk of mortality is increased by 41% in patients with RA compared to the general population. Excessive all-cause mortality risk is higher in men than in women. National data showed lower standardized mortality compared to literature data.

Background:Cohort studies using nationwide health registers have shown an increased risk for affective and anxiety disorders in people with ankylosing spondylitis (AS) and rheumatoid arthritis (RA) (1-3). Moreover, a nationwide cohort study demonstrated an increased risk for mental disorders in people with rheumatic diseases (4).Objectives:We aimed to investigate the risk for psychiatric hospitalization following a hospitalization for rheumatic disease.Methods:Using data from the Czech nationwide register of all-cause hospitalizations, we obtained 4 971 individuals hospitalized (index hospitalization) between 2004 and 2012 for rheumatic diseases - RA, spondyloarthritis (including AS, psoriatic arthritis and undifferentiated spondyloarthritis), systemic lupus erythematosus and systemic sclerodermia, with no history of psychiatric and rheuma-related hospitalization in the previous 10 years from the index hospitalization. On these individuals, we randomly matched (on age, gender and year of index hospitalization) controls that were hospitalized in the same time period for a non-rheumatic disease and have no history of psychiatric and rheumatic hospitalization in the last 10 years from their index hospitalization, in the ratio of 1:5. We employed conditional logistic regression for assessing the risk for psychiatric hospitalization in the subsequent 3 years from the index hospitalization. To strengthen our results, we repeated the matching step 100 times and run the analysis on each resulting dataset separately, and pooled the results. The findings are expressed as odds ratios (OR) with 95% confidence intervals (95% CI).Results:We identified an elevated risk for psychiatric (OR = 1.34, 95% CI = 1; 1.78) and for affective disorders (OR = 2.19, 95% CI = 1.17; 4.1) in people hospitalized for rheumatic diseases. We did not find a statistically significant association with organic, psychotic and anxiety disorders.Conclusion:There is an increased risk for experiencing a psychiatric disorder in the period of 3 years after a rheuma-related hospitalization.References:[1]Shen C-C, Hu L-Y, Yang AC, Kuo BI-T, Chiang Y-Y, Tsai S-J.

Abstract Background Some observational studies have found a significant association between the use of statin and a reduced risk of dementia. However, the results of these studies are unclear in patients with rheumatoid arthritis (RA). This study is to determine the association between the use of statins and the incidence of dementia according to sex and age-related differences in patients with RA. Methods We conducted a nationwide retrospective cohort study using the Taiwan Health Insurance Review and Assessment Service database (2003–2016). The primary outcome assessed was the risk of dementia by estimating hazard ratios (HRs) and 95% confidence intervals (CIs). Multiple Cox regression was used to estimate the adjusted hazard ratio of new-onset dementia. Subgroup analysis was also conducted. Results Among the 264,036 eligible patients with RA aged > 40 years, statin users were compared with non-statin users by propensity score matching at a ratio of 1:1 (25,764 in each group). However, no association was found between the use of statins and the risk of new-onset dementia (NOD) in patients with RA (HR: 1.01; 95% CI: 0.97–1.06). The subgroup analysis identified the use of statin as having a protective effect against developing NOD in male and older patients. Conclusion No association was observed between the use of a statin and the risk of NOD in patients with RA, including patients of both genders and aged 40–60 years, but these parameters were affected by gender and age. The decreased risk of NOD in patients with RA was greater among older male patients. Use of a statin in older male (> 60 years) patients with RA may be needed in clinical practice to prevent dementia.
