Assessment of adherence to disease-modifying anti-rheumatic drugs in rheumatoid arthritis

Adherence to the antirheumatic drugs: a systematic review and meta-analysis

Introduction

This systematic review and meta-analysis aimed to analyze the adherence rate for conventional and biological disease-modifying antirheumatic drugs (DMARDs) utilizing different assessment measures.

Method

A systematic literature search was performed in four electronic databases, including PubMed, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL), covering the time frame from April 1970 to April 2023. Studies that present data on medication adherence among adult patients with rheumatoid arthritis (RA), specifically focusing on DMARDs (conventional or biological), were included in the analysis. The adherence rate for different assessment measures was documented and compared, as well as for conventional and biological DMARDs. A random-effects meta-analysis was performed to assess adherence rates across different adherence assessment measures and drug groups.

Results

The search identified 8,480 studies, out of which 66 were finally included in the analysis. The studies included in this meta-analysis had adherence rates ranging from 12 to 98.6%. Adherence rates varied across several adherent measures and calculation methods. Using the subjective assessment measures yielded the outcomes in terms of adherence rate: 64.0% [0.524, 95% CI 0.374-0.675] for interviews and 60.0% [0.611, 95% CI 0.465-0.758] for self-reported measures (e.g., compliance questionnaires on rheumatology CQR-5), p > 0.05. In contrast, the objective measurements indicated a lower adherence rate of 54.4% when using the medication event monitoring system (p > 0.05). The recorded rate of adherence to biological DMARDs was 45.3% [0.573, 95% CI 0.516-0.631], whereas the adherence rate for conventional DMARDs was 51.5% [0.632, 95% CI 0.537-0.727], p > 0.05. In the meta-regression analysis, the covariate "Country of origin" shows a statistically significant (p = 0.003) negative effect with a point estimate of -0.36, SE (0.12), 95% CI, -0.61 to -0.12.

Discussion

Despite its seemingly insignificant factors that affect the adherence rate, this meta-analysis reveals variation in adherence rate within the types of studies conducted, the methodology used to measure adherence, and for different antirheumatic drugs. Further research is needed to validate the findings of this meta-analysis before applying them to clinical practice and scientific research. In order to secure high reliability of adherence studies, compliance with available reporting guidelines for medication adherence research is more than advisable.

Urinary methotrexate dosage in rheumatoid arthritis, in patients treated for at least 6 months: a potential marker of adherence

OBJECTIVES

Non-adherence to rheumatoid arthritis (RA) treatments must be identified. A methotrexate (MTX) urinary dosage (METU) was recently developed. The aim of our study was to assess adherence to MTX in RA using METU in real-life conditions and to compare it with indirect adherence measurement technics.

METHODS

We performed a cross-sectional study at Reims University Hospital. We included over 18-year-old patients with RA treated by MTX for more than 6 months. Patients were invited to complete demographic, clinical and psychological questionnaires and adherence measurement technics (Compliance Questionnaire of Rheumatology (CQR) and Medication Possession Ratio (MPR)). A urinary sample was collected to measure MTX and information about tolerance was evaluated through Methotrexate Intolerance Severity Score.

RESULTS

84 patients were included, 26 using oral MTX, 58 subcutaneous (SC) MTX. Among them, 73% were female, mean age was 61.5 years, MTX mean dose was 15 mg/week and 61.9% were treated by biological DMARDs (Disease Modifying Antirheumatic Drugs). 77 patients (91.7%) were adherent to treatment according to METU, whereas MPR and CQR reported less adherence (69.5% and 61.9%, respectively). MPR and METU were not significantly different in SC MTX users (p=0.059). Non-adherent patients had a higher number of tender joints and C reactive protein value (p<0.05).

CONCLUSION

This is the first largest study evaluating MTX adherence in patients with RA using a urinary dosage. We identified that indirect adherence measurements did not reflect real-life adherence. It would be appreciable to realise METU, in a new study, in patients with RA with unexplained response to treatment, to consider it before escalating therapeutic strategy.

Frequency of irritable bowel syndrome in spondyloarthritis: a multicentric cross-sectional study and meta-analysis

OBJECTIVE

To evaluate the prevalence of symptoms and factors associated with irritable bowel syndrome (IBS) in axial spondyloarthritis (ax-SpA).

METHODS

In a cross-sectional multicentric study, consecutive patients with ax-SpA treated with biologics in five rheumatology departments were asked for IBS Rome IV criteria. Demographic data, lifestyle behaviours and disease characteristics were recorded. Second, a systematic literature review and meta-analysis were performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Of the 500 patients with ax-SpA included, 124 reported IBS symptoms (25%). Female gender, unemployment, higher Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and worse Bath Ankylosing Spondylitis Functional Index scores, multiple lines of biologics, fibromyalgia, anxiety, depression and lower physical activity were associated with IBS symptoms. In multivariate model, the risk of IBS was associated with anxiety and physical inactivity. From the literature review, the prevalence of IBS in patients with SpA was 15.4% (8.8% to 23.3%). Meta-analysis of the five studies comparing the presence of IBS in patients with SpA (323/7292) and healthy controls (484/35587) showed a significant increase of IBS in patients with SpA (OR=1.59 (1.05 to 2.40)).

CONCLUSION

The prevalence of IBS symptoms was high in the ax-SpA population and should therefore be considered in the presence of gastrointestinal disorders. The presence of IBS symptoms was associated with anxiety and low physical activity in multivariate analysis. Patients with IBS symptoms tended to have more difficult to manage disease characterised by higher activity, worse functional score and multiple lines of treatment in univariate analysis.

Exploring Factors Influencing Medication Compliance in Saudi Rheumatoid Arthritis Patients: A Nationwide Cross-Sectional Survey - Results from the COPARA Study

PURPOSE

Compliance is essential to achieve treatment goals in rheumatoid arthritis (RA) patients. The current study evaluated compliance and related factors in a large and diverse population.

PATIENTS AND METHODS

Patients with RA who received active treatment were invited to participate in an online survey. The Arabic versions of the 5-Item Compliance Questionnaire for Rheumatology (ACQR-5) and the RA Impact of Disease (RAID) were used to measure compliance and disability, respectively. The patients were sub-grouped based on background disease-modifying anti-rheumatic drugs (DMARDs). Variables associated with high compliance were selected for the logistic regression analysis.

RESULTS

A total of 1241 patients completed the survey and were included in the final analysis. Of those, 1055 (85%) were females with a mean (±SD) age and disease duration of 47.14 ± 13.71 and 8.77 ± 7.43 years, respectively. The mean RAID was 4.4±2.58, with 980 (79%) having an unacceptable level state. Patients with an unacceptable RAID level had a lower compliance rate (78.8% vs 85.8%, p = 0.001). Demographics associated with high compliance were female sex and increased age, with reported odds ratios of 1.018 (95% CI: 1.007-1.028) and 1.464 (95% CI: 1.016-2.108), respectively. Compliance was similar between patients on Janus kinase inhibitors or biological DMARDs (88.14% vs 80.83%, p = 0.17), between monotherapy, double therapy, or triple therapy recipients (80% vs 82.23% vs 81.32%, p = 0.665), and between patients receiving injectable and oral therapy (77.32% vs 81.14%, p = 0.246).

CONCLUSION

A high compliance level was observed in this population, with patient demographics influencing compliance rather than the medication type or route of administration. Interventional studies should focus on the of high-risk patients identified in this study.

Assessment of physical function, quality of life, and medication adherence in elderly patients with rheumatic diseases

Background

The proportion of older people in the total population has increased in Turkey as well as worldwide. As life expectancy rises, the increasing prevalence of rheumatic diseases poses major problems in the elderly. Comorbid diseases and the aging-induced changes in the endogenous immune response and the pharmacokinetic properties of therapeutic agents may complicate the decision to use a particular drug and result in a different clinical picture and treatment response. We, therefore, aimed to investigate the characteristics of chronic inflammatory diseases, their impact on physical function and quality of life, the prevalence of comorbid diseases that may complicate treatment planning, and treatment adherence in patients aged 65 years or older.

Results

One hundred seventy-four patients were included and divided into two age groups: 18–64 years (group 1, n = 85) and 65 years or older (group 2, n = 89). The mean age of all recruited patients was 57.55 ± 16.98 years. Of 174, 99 (56.9%) were female and 75 (43.1%) were male. The mean duration of rheumatic disease was 7 ± 4.8 years and age at onset was 51.46 ± 14.78 years. Gender distribution differed significantly by age group (P = 0.024). The percentage of females in group 1 was 48.2% and 65.2% in group 2. The occupational status also differed significantly by age group (P < 0.001). 48.2% of group 1 were employed and 57.3% of group 2 were housewives. Marital status varied significantly by age (P < 0.001). The percentage of married was 74.1% in group 1 and the percentage of separated/divorced/widowed in group 2 was 28.1%. There was no difference between groups 1 and 2 in terms of place of residence (P = 0.459). The prevalence of comorbid diseases and the rate of use of medications for comorbid diseases (non-rheumatic treatments) were higher in elderly patients. The rate of use of disease-modifying anti-rheumatic drugs (DMARDs) was 30.3% and biological agents 61.8% in the elderly group (≥ 65 years) (group 2) (P < 0.001). There were positive correlations between, Health Assessment Questionnaire (HAQ), Bath Ankylosing Spondylitis Functional Index (BASFI) and Nottingham Health Profile (NHP) domains in both groups. There was also a significant negative correlation between Medication Adherence Rating Scale (MARS) and all dimensions.

Conclusions

Elderly and younger patients with rheumatic diseases have different demographic and clinical characteristics. Physical function and quality of life are more affected by rheumatic diseases and treatment adherence is poorer in the elderly. Our study found a positive correlation between physical function and quality of life in both age groups. The treatment adherence rating scale showed a negative correlation with physical function and quality of life scores, with individuals with poor treatment adherence having worse physical function and quality of life.

Prevalence of complementary and alternative medicine despite limited perceived efficacy in patients with rheumatic diseases in Mexico: Cross-sectional study

INTRODUCTION

Complementary and alternative medicine (CAM) is frequently used by patients with rheumatic diseases (RD) to improve their symptoms; however, its diversity and availability have increased notably while scientific support for its effectiveness and adverse effects is still scarce.

OBJECTIVE

To describe the prevalence and diversity of CAM in patients with RD in Chihuahua, Mexico.

METHODS

A cross-sectional study was conducted in 500 patients with RD who were interviewed about the use of CAM to treat their disease. The interview included sociodemographic aspects, characteristics of the disease, as well as a description of CAM use, including type, frequency of use, perception of the benefit, communication with the rheumatologist, among others.

RESULTS

The prevalence of CAM use was reported by 59.2% of patients, which informed a total of 155 different therapies. The herbal CAM group was the most used (31.4%) and included more than 50 different therapies. The use of menthol-based and arnica ointments was highly prevalent (35%). Most patients (62.3%) reported very little or no improvement in their symptoms. Only a fourth of the patients informed the rheumatologist of the use of CAM. The use of CAM was influenced by female sex, university degree, diagnosis delay, lack adherence to the rheumatologist's treatment, family history of RD, and orthopedic devices.

CONCLUSION

The use of CAM in our population is highly prevalent and similar to reports in different populations suggesting a widespread use in many different societies. We found high use of herbal remedies; however, there were many different types suggesting a lack of significant effect. Patients continue using CAM despite a perception of no-effectiveness. Recurrent use of CAM is explained by factors other than its efficacy.

[Compliance with biologic agents: Current situation]

Despite the fact that the prognosis of chronic inflammatory disorders is improved by biological agents, compliance with those therapeutics remains imperfect. Compliance corresponds to the measurable part of the follow-up of the medical prescription by the patient, whereas adherence is related to the acceptation of the treatment by the patient. The compliance rates of biologic agents are generally higher than those of conventional therapies. Compliance can be influenced by the real or experienced efficacity of the treatment, by patient-related factors or by the patient-physician relationship. An increase of compliance is associated with an improvement of adherence. To achieve this, the physician can use educational measures such as patient education, which allows the identification of poor adherence. Such programs have been shown to improve the patient's knowledge of the disease and treatment leading to better adherence and compliance.
