Patient Perceptions concerning Pain Management in the Treatment of Rheumatoid Arthritis

Abstract: Previous qualitative studies have revealed discrepancies between patients' and physicians' perceptions of rheumatoid arthritis (RA) and its treatment. Questionnaires were administered to 2795 patients with RA (756 from Europe; 2039 from the USA) to measure patients' perceptions regarding pain management in RA. Although the majority of patients reported their RA as somewhat-to-completely controlled, 75% of European and 82% of US patients reported their pain as moderate-to-severe in the previous 2 months. The majority of European (60%) and US (65%) patients reported dissatisfaction with their arthritis pain. Patients' pain levels corresponded with their disease severity. A higher percentage of patients who reported severe pain were being treated for depression than those who had moderate or mild pain. Patients in the USA rated pain relief as the top required benefit from their RA medication. A comprehensive examination of patients' perspectives regarding pain could lead to better patient care and pain management strategies.

Golimumab, a new human anti-tumor necrosis factor alpha antibody, administered intravenously in patients with active rheumatoid arthritis: Forty-eight-week efficacy and safety results of a phase III randomized, double-blind, placebo-controlled study.

Abstract: Objective To assess the efficacy and safety of intravenous administration of golimumab in patients with rheumatoid arthritis (RA). Methods Adult patients with RA in whom disease activity was persistent despite treatment with methotrexate (MTX) at a dosage of 15–25 mg/week for ≥4 weeks were randomized to receive intravenous infusions of placebo plus MTX or intravenous infusions of golimumab at a dose of 2 mg/kg or 4 mg/kg, with or without MTX, every 12 weeks through week 48. Patients with <20% improvement in the swollen and tender joint counts could enter early escape and receive additional active treatment (week 16) or could have their dose regimen adjusted (week 24). The primary end point was the proportion of patients achieving a 50% response according to the American College of Rheumatology improvement criteria (ACR50) at week 14. Results The primary study end point was not met (at week 14, an ACR50 response was observed in 21% of the patients treated with golimumab plus MTX compared with 13% of the patients treated with placebo plus MTX [P = 0.051]). By week 24, significantly more patients treated with golimumab plus MTX had achieved an ACR50 response. Differences in the proportion of patients achieving an ACR50 response between the group receiving golimumab monotherapy and the group receiving placebo plus MTX were not significant at either week 14 (16% versus 13%) or week 24 (10% versus 9%). At week 48, the proportions of patients achieving ACR20 and ACR50 responses were highest among those who had received golimumab 4 mg/kg plus MTX (70% and 48%, respectively). Concomitant treatment with MTX was associated with a lower incidence of antibodies to golimumab. The most commonly reported adverse events through week 48 were infections (48% of patients treated with golimumab with or without MTX and 41% of patients receiving placebo plus MTX). Conclusion The primary end point was not met. However, intravenously administered golimumab plus MTX appears to have benefit in the longer-term reduction of RA signs/symptoms in MTX-resistant patients, with no unexpected safety concerns.

Physical function improvements and relief from fatigue and pain are associated with increased productivity at work and at home in rheumatoid arthritis patients treated with certolizumab pegol

Abstract: Objectives. To evaluate the association between improvements in physical function, fatigue and pain and improvements in productivity at work and at home in patients treated with certolizumab pegol (CZP) in combination with MTX. Methods. Physical function, fatigue and pain were assessed in two CZP clinical trials (Rheumatoid Arthritis PreventIon of structural Damage 1 and 2) using the HAQ-Disability Index (HAQ-DI), Fatigue Assessment Scale (FAS) and Patient Assessment of Pain, with minimal clinically important differences (MCIDs) defined as ≥0.22, ≥1 and ≥10 points, respectively. Work and home productivity were evaluated using the RA-specific Work Productivity Survey (WPS-RA). The odds of achieving an HAQ-DI, FAS or pain ‘response’ at Week 12, defined as improvements ≥MCID, were compared between CZP and control groups. Improvements in productivity at Week 12 were compared between CZP-treated HAQ-DI, FAS or pain responders and non-responders. Results. The odds of achieving improvements ≥MCID were five times higher for pain, and two to three times higher for physical function and fatigue, in patients receiving CZP vs control. Per month, responders reported significantly greater improvements in productivity at work and reduced interference of RA with their work productivity than non-responders. Responders also reported significantly greater improvements in productivity at home and participation in family, social and leisure activities. Conclusions. This study demonstrated a clear association between patient-reported improvements in physical function, fatigue and pain, and improvements in productivity both at work and home.

Gender, body mass index and rheumatoid arthritis disease activity: results from the QUEST-RA Study.

Abstract: OBJECTIVES: To investigate whether body mass index (BMI), as a proxy for body fat, influences rheumatoid arthritis (RA) disease activity in a gender-specific manner. METHODS: Consecutive patients with RA were enrolled from 25 countries into the QUEST-RA program between 2005 and 2008. Clinical and demographic data were collected by treating rheumatologists and by patient self-report. Distributions of Disease Activity Scores (DAS28), BMI, age, and disease duration were assessed for each country and for the entire dataset; mean values between genders were compared using Student's t-tests. An association between BMI and DAS28 was investigated using linear regression, adjusting for age, disease duration and country. RESULTS: A total of 5,161 RA patients (4,082 women and 1,079 men) were included in the analyses. Overall, women were younger, had longer disease duration, and higher DAS28 scores than men, but BMI was similar between genders. The mean DAS28 scores increased with increasing BMI from normal to overweight and obese, among women, whereas the opposite trend was observed among men. Regression results showed BMI (continuous or categorical) to be associated with DAS28. Compared to the normal BMI range, being obese was associated with a larger difference in mean DAS28 (0.23, 95% CI: 0.11, 0.34) than being overweight (0.12, 95% CI: 0.03, 0.21); being underweight was not associated with disease activity. These associations were more pronounced among women, and were not explained by any single component of the DAS28. CONCLUSIONS: BMI appears to be associated with RA disease activity in women, but not in men.

Towards understanding the phenotypes of myocardial involvement in the presence of self-limiting and sustained systemic inflammation: a magnetic resonance imaging study

Abstract: Objective. To investigate the patterns of myocardial involvement in the presence of self-limiting and sustained systemic inflammation, using MRI. Methods. Ninety-four subjects, with a clinical diagnosis of myocarditis (n = 36), RA (n = 24) and apparently healthy subjects (n = 34, control group), underwent standardized cardiac MRI protocol for the assessment of global and regional morphology and systolic function using balanced steady-state free precession sequences, T2-weighted images and late gadolinium enhancement (LGE) studies. Results. The three groups were well matched for age, gender and cardiovascular risk factors. The RA group showed markedly increased end-diastolic volumes and reduced ejection fraction (P < 0.05). Antero/inferolateral wall thickness was greater in the myocarditis group and reduced in RA, associated with reduced radial and longitudinal thickening (P < 0.01), and markedly raised T2-oedema ratio and global LGE scores (P < 0.05). Conclusions. Our results may signify the phenotypic features of myocardial plasticity and deformation in response to self-limiting and sustained inflammatory injury.

Quantitative Power Doppler Ultrasonography Is a Sensitive Measure of Metacarpophalangeal Joint Synovial Vascularity in Rheumatoid Arthritis and Declines Significantly Following a 2-week Course of Oral Low-dose Corticosteroids

Abstract: Objective. To investigate the stability over 2 weeks of ultrasonographic assessments of synovial thickness and vascularity in all 10 metacarpophalangeal joints of subjects with rheumatoid arthritis (RA) with a range of disease activities as measured by the validated Disease Activity Score-28 joint score (DAS28-ESR). And in subjects with severe disease activity, to compare the sensitivity of these measurements, acute-phase markers, and vascular endothelial growth factor to change in response to 2 weeks of oral prednisolone (7.5 mg daily). Methods. A group of 38 subjects with RA were enrolled, 13 (mean DAS28 2.1), 14 (mean DAS28 5.2), and 11 (mean DAS28 5.7) meriting oral corticosteroid treatment. Synovial thickness and vascularity were assessed by ultrasonography at 3 timepoints. Images were ranked by semiquantitative scale. Vascularity was also measured by quantitative determination of the power Doppler area (PDA). Results. In the whole RA cohort, baseline indices of synovial thickness and vascularity correlated with DAS28, as did PDA (r = 0.42, p < 0.05). In the RA groups on stable therapy, synovial thickness and vascularity showed little variation over 2 weeks. In the corticosteroid group, PDA had fold changes of −1.9-fold (p < 0.05) after 1 week and −2.2-fold (p < 0.05) after 2 weeks. These were the largest fold changes of all measured variables. Conclusion. Ultrasonographic measures can differentiate disease severity in RA correlating closely with DAS28. Quantitative power Doppler signal was significantly reduced within 1 week of oral prednisolone, a rapid kinetic suggesting that PDA may have value as a sensitive early marker of therapeutic response.

The importance of the patients' experience of RA compared with clinical measures of disease activity.

Abstract: Improvements in rheumatoid arthritis (RA) treatment have led to an increased focus on specialised and validated outcome measures, resulting in a decrease in the use of subjective assessments such as patient perceptions. However, to achieve optimal outcomes in the treatment of RA, there is a need to balance clinical goals with those that may be more important to patients. Although the treatment goals of physicians and patients are generally aligned, the framework in which these goals are expressed differs widely, and there are pronounced differences in how patients and physicians view their interactions regarding the decision-making process about treatment and information sharing. Detailed discussion between the physician and the patient regarding the patient’s perspectives can lead to valuable insights into the patient’s unmet needs from treatment as well as enhancement of the physician-patient relationship and an overall improvement in patients’ quality of life.
