Risk of infection with biologic antirheumatic therapies in patients with rheumatoid arthritis

There are currently 10 licensed biologic therapies for the treatment of rheumatoid arthritis in 2014. In this article, we review the risk of serious infection (SI) for biologic therapies. This risk has been closely studied over the last 15 years within randomised controlled trials, long-term extension studies and observational drug registers, especially for the first three antitumour necrosis factor (TNF) drugs, namely infliximab, etanercept and adalimumab. The risk of SI with the newer biologics rituximab, tocilizumab, abatacept and tofacitinib is also reviewed, although further data from long-term observational studies are awaited. Beyond all-site SI, we review the risk of tuberculosis, other opportunistic infections and herpes zoster, and the effect of screening on TB rates. Lastly, we review emerging opportunities for stratifying the risk. Patients can be risk-stratified based on both modifiable and non-modifiable patient characteristics such as age, co-morbidity, glucocorticoid use, functional status and recent previous SI.

Health-related quality of life and its predictors among patients with rheumatoid arthritis

BACKGROUND Limited studies have examined the predictors of HRQoL among patients with rheumatoid arthritis. This study helped to ascertain the predictors of HRQoL from the pool of influencing factors identified by previous studies. AIM This study investigated the health-related quality of life (HRQoL) of adult patients with rheumatoid arthritis and its predictors. METHODS Using a descriptive correlational design, this study explored the relationship between HRQoL and pain, functional disability, anxiety, depression, medication adherence and social support. Eligible outpatients (n=108) were recruited via their attending doctors who were co-investigators of this study. Informed consent forms were distributed and questionnaires administered in a teaching hub by the main researcher. RESULTS Significant correlations were found between HRQoL and all of the study variables. Pain, functional disability and depression were main predictors of HRQoL. CONCLUSIONS Future evidence-based interventions focusing on pain relief, delaying disability or improving functional ability and reducing depressive symptoms are required to enhance the HRQoL of patients with rheumatoid arthritis.

Exploring new healthcare professionals’ roles through interprofessional education

Abstract This article presents findings from a simulation-based interprofessional education (IPE) program involving trainee advanced practice nurses (APNs) and internal medicine residents (IMRs) based in Singapore. Trainee APNs and IMRs participated in a semester-long series of high-fidelity simulations of medical emergencies. Learners’ attitudes toward the IPE intervention were assessed using validated Likert scaled surveys and written comments. Overall satisfaction was high among learners, with strongly positive attitudes toward teamwork, collaboration and patient centredness. Of most interest, written comments highlight the utility of IPE in defining the professional scope and boundaries of APNs. Comments from both professions observed that participation in the IPE scenarios greatly aided their understanding of the scope and role of APN’s practice within the health care team. This aspect of IPE may find further application in other similarly novel roles in healthcare.

Atherogenic serum lipid profile is an independent predictor for gouty flares in patients with gouty arthropathy

OBJECTIVE Atherogenic serum lipid profile possesses pro-inflammatory properties and is associated with more active RA. While prevalent in patients with gout, whether atherogenic lipid profile is associated with gouty flares is unknown. This study aims to investigate whether atherogenic serum lipid predicts gouty flares in patients with gout. METHODS Adult patients (age > or =21 yrs) who suffered from gout were prospectively followed between September 2006 and November 2007 and their demographic, clinical and laboratory data were collected. Episodes of gouty flares over this observation period were recorded and factors predictive of gouty flares were studied by regression models. RESULTS Of the 100 patients, 80 were men, 65 were ethnic Chinese, 31 were Malay and the rest were Indian and Caucasian. The mean age and duration of gout (+/-S.D.) were 61.9 +/- 14.0 and 6.6 +/- 7.8 yrs, respectively. The mean serum uric acid and creatinine levels were 537.6 +/- 142.8 and 173.6 +/- 119.9 micromol/l, respectively. In univariate analysis, longer duration of gout, higher adjusted mean serum creatinine, lower adjusted mean fasting serum, total cholesterol and high-density lipoprotein cholesterol (HDL-C) levels were associated with gouty flares. After adjustment for potential confounders in multivariate regression models, longer duration of gout and lower adjusted mean fasting serum HDL-C level remained independently predictive of gouty flares. CONCLUSIONS Low serum high-density lipoprotein cholesterol level was an independent predictor for gouty flares. Whether optimizing serum HDL-C level can benefit patients with gout in terms of reducing gouty flares needs to be addressed by controlled trials.

A randomized controlled trial for improving patient self-assessment of synovitis in rheumatoid arthritis with education by ultrasonography: the RAEUS Study

OBJECTIVE Patients can potentially monitor disease activity of RA through self-assessed swollen joints (clinical synovitis), but reliability is poor. The objective is to evaluate the use of education by US feedback on the ability of patients to assess for clinical synovitis in RA. METHODS We performed a 6 month, single-centre, randomized controlled trial on patients with established RA to study the effect of education on self-assessment of joints that included initial brief patient training on tender (TJC) and swollen (SJC) joint counts followed by US feedback every 3 months vs standard care without education. Patient and physician independently performed 28-joint counts at each visit. Outcome variables included the percentage of patients with good agreement with physician-derived swollen joints [prevalence-adjusted bias-adjusted kappa (PABAK) >0.6] as well as agreement in the SJC (Bland and Altman 95% limits of agreement), feasibility/patient satisfaction survey and disease activity at 6 months. RESULTS Of the 101 randomized patients, 95 were included (51 in the education arm and 44 in the standard care arm). At 6 months there was a significant difference in the proportion of patients with swollen joint PABAK >0.6 in the education arm compared with standard care (98 vs 85%, P = 0.02). Limits of agreement for the SJC difference between physician and patients were reduced only in the education arm. The training method is considered feasible, with 94% of patients reporting it as useful. A trend of higher rates of disease remission (28-joint DAS <2.6) in the education arm vs standard care (47% vs 29%, P = 0.07) was seen. CONCLUSION A short course of education with US feedback may be helpful in educating patients to assess for clinical synovitis.

Experiences of Patients With Rheumatoid Arthritis: A Qualitative Study.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that greatly impacts one’s physical and psychosocial well-being. The purpose of this study was to explore the experiences and support needs of adult patients living with RA. A descriptive qualitative study was conducted, and 16 adults with RA were interviewed from October 2013 to January 2014. The transcribed data were analyzed using thematic analysis. Five themes were identified: altered physical capacity and well-being, psychological and emotional challenges, changes in social life, coping strategies, and support received and further support needs. This study provided insights into the experiences and support needs of patients with RA in Singapore. Physical and psychosocial challenges experienced by patients affected their daily and social activities. Patients’ needs for variety of support should be addressed.

Use of complementary and alternative medicines is associated with delay to initiation of disease‐modifying anti‐rheumatic drug therapy in early inflammatory arthritis

To study the predictors of complementary and alternative medicine (CAM) use in patients with early inflammatory arthritis (EIA), and its impact on delay to initiation of disease‐modifying anti‐rheumatic drugs (DMARD).

Consensus development on eligibility of government subsidisation of biologic disease modifying anti-rheumatic agents for treatment of ankylosing spondylitis: The Singapore experience

The beneficial effects of biologic disease‐modifying anti‐rheumatic drugs (bDMARDs), such as tumour necrosis factor inhibitors (anti‐TNF) in active ankylosing spondylitis (AS) are well established. The significant costs on patients in the absence of financial subsidization can limit their use. The objective was to describe a consensus development process on recommendations for government‐assisted funding of biologic therapy for AS patients in Singapore.

Increasing podiatry referrals for patients with inflammatory arthritis at a tertiary hospital in Singapore: A quality improvement project

BACKGROUND Foot disease is highly prevalent in people with inflammatory arthritis and is often under-recognized. Podiatry intervention can significantly reduce foot pain and disability, with timely access being the key factor. The aim of this study was to plan and implement a quality improvement project to identify the barriers to, and improve, uptake of podiatry services among patients with inflammatory arthritis-related foot problems seen at a tertiary hospital in Singapore. METHOD A 6-month quality improvement program was conducted by a team of key stakeholders using quality improvement tools to identify, implement and test several interventions designed to improve uptake of podiatry services. The number of patients referred for podiatry assessment was recorded on a weekly basis by an experienced podiatrist. The criterion for appropriate referral to podiatry was those patients with current or previous foot problems such as foot pain, swelling and deformity. RESULTS Interventions included education initiatives, revised workflow, development of national guidelines for inflammatory arthritis, local podiatry guidelines for the management of foot and ankle problems, routine use of outcome measures, and introduction of a fully integrated rheumatology-podiatry service with reduced cost package. Referral rates increased from 8% to 11%, and were sustained beyond the study period. Complete incorporation of podiatry into the rheumatology consultation as part of the multidisciplinary team package further increased referrals to achieve the target of full uptake of the podiatry service. CONCLUSION Through a structured quality improvement program, referrals to podiatry increased and improved the uptake and acceptance of rheumatology-podiatry services.

Singapore Chapter of Rheumatologists consensus statement on the eligibility for government subsidy of biologic disease modifying anti-rheumatic agents for the treatment of psoriatic arthritis

In Singapore, patients with psoriatic arthritis (PsA) constitute a significant disease burden. There is good evidence for the efficacy of anti‐tumor necrosis factor (anti‐TNF) in PsA; however cost remains a limiting factor. Non‐biologic disease modifying anti‐rheumatic drugs (nbDMARDs) hence remain the first‐line treatment option in PsA in spite of limited evidence. The Singapore Chapter of Rheumatologists aims to develop national guidelines for clinical eligibility for government‐assisted funding of biologic disease modifying anti‐ rheumatic drugs (bDMARDs) for PsA patients in Singapore.
