Increased Risk of Chronic Kidney Disease in Rheumatoid Arthritis Associated with Cardiovascular Complications - A National Population-Based Cohort Study.

ABSTRACT:

Background and objectives

There have been few large population-based studies of the association between rheumatoid arthritis (RA) and chronic kidney disease (CKD) and glomerulonephritis. This nationwide cohort study investigated the risks of developing CKD and glomerulonephritis in patients with RA, and the associated risks for cardiovascular complications.

Methods

From the Taiwan National Health Insurance Research Database, we identified a study cohort of 12,579 patients with RA and randomly selected 37,737 subjects without RA as a control cohort. Each subject was individually followed for up for 5 years, and the risk of CKD was analyzed using Cox proportional hazards regression models.

Results

During the follow-up period, after adjusting for traditional cardiovascular risk factors RA was independently associated with a significantly increased risk of CKD (adjusted hazard ratio [aHR] 1.31; 95% confidence interval [CI] 1.23-1.40) and glomerulonephritis (aHR 1.55; 95% CI 1.37-1.76). Increased risk of CKD was also associated with the use of non-steroidal anti-inflammatory drugs, cyclosporine, glucocorticoids, mycophenolate mofetil, and cyclophosphamide. Patients with comorbidities had even greater increased risk of CKD. Moreover, RA patients with concurrent CKD had significantly higher likelihood of developing ischemic heart disease and stroke.

Conclusions

RA patients had higher risk of developing CKD and glomerulonephritis, independent of traditional cardiovascular risk factors. Their increased risk of CKD may be attributed to glomerulonephritis, chronic inflammation, comorbidities, and renal toxicity of antirheumatic drugs. Careful monitoring of renal function in RA patients and tight control of their comorbid diseases and cardiovascular risk factors are warranted.

Project description:Background:Chronic inflammatory arthritis is associated with increased cardiovascular (CV) morbidity and mortality. Pharmacological management and healthy lifestyle modification is recommended to manage these risks, but it is not known how often these are utilised and whether there is any difference in their use between patients with different types of arthritis. The aim of this study was to determine and compare the proportion of participants with rheumatoid arthritis (RA) and psoriatic arthritis (PsA) receiving pharmacological or lifestyle management strategies for CV risk factors. The secondary objective was to identify factors associated with use of management strategies. Methods:A survey was sent to online participants in the Australian Rheumatology Association Database, a voluntary national registry for inflammatory arthritis. Participants were asked whether they took medications for hypertension, hyperlipidaemia and diabetes, and to report their height, weight, level of physical activity, and dietary changes made. The use of management strategies was compared between participants with RA and PsA. Logistic regression analyses were performed to identify factors associated with physical activity and dietary changes. Results:There were 858 respondents with RA and 161 with PsA (response rate 64.5%). Pharmacological treatment was reported by 93% of participants with hypertension and 70% with hyperlipidaemia. All participants with diabetes reported being managed with dietary modification, pharmacological treatment, or a combination of both. Adequate physical activity was reported by 50.8%. Only 27% of overweight or obese participants reported making any dietary change for their health in the past year. There was no difference between RA and PsA in reported utilisation of management strategies. Hyperlipidaemia and being overweight were associated with making dietary change. Obesity and arthritis disease activity were negatively associated with physical activity. Conclusions:Most participants with RA and PsA reported using pharmacological treatment for CV risk factors. Relatively few reported using lifestyle modifications. Targeted lifestyle interventions should be implemented for RA and PsA patients.

Project description:BackgroundRheumatoid arthritis (RA) and ankylosing spondylitis (AS) are associated with mental illness. Whether acute mental health (MH) service utilization (i.e. emergency visits or hospitalizations) is increased in RA or AS is not known.MethodsTwo population-based cohorts were created where individuals with RA (n?=?53,240) or AS (n?=?13,964) were each matched by age, sex, and year to unaffected comparators (2002-2016). Incidence rates per 1000 person-years (PY) were calculated for a first MH emergency department (ED) presentation or MH hospitalization. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated, adjusting for demographic, clinical, and health service use variables.ResultsIndividuals with RA had higher rates of ED visits [6.59/1000 person-years (PY) versus 4.39/1000 PY in comparators] and hospitalizations for MH (3.11/1000 PY versus 1.80/1000 PY in comparators). Higher rates of ED visits (7.92/1000 PY versus 5.62/1000 PY in comparators) and hospitalizations (3.03/1000 PY versus 1.94/1000 PY in comparators) were also observed in AS. Overall, RA was associated with a 34% increased risk for MH hospitalization (HR 1.34, 95% CI 1.22-1.47) and AS was associated with a 36% increased risk of hospitalization (HR 1.36, 95% CI 1.12-1.63). The risk of ED presentation was attenuated, but remained significant, after adjustment in both RA (HR 1.08, 95% CI 1.01-1.15) and AS (HR 1.14, 95% CI 1.02-1.28).ConclusionsRA and AS are both independently associated with a higher rate and risk of acute ED presentations and hospitalizations for mental health conditions. These findings underscore the need for routine evaluation of MH as part of the management of chronic inflammatory arthritis. Additional research is needed to identify the underlying individual characteristics, as well as system-level variation, which may explain these differences, and to help plan interventions to make MH service use more responsive to the needs of individuals living with RA and AS.
