Abstract
Objective This study was conducted with the aim of evaluating the cost-effectiveness of and adherence to treatment in patients on disease-modifying antirheumatic drug (DMARD) therapy for rheumatoid arthritis (RA) in a tertiary care teaching hospital in Uttarakhand, India. Methodology This prospective observational study was conducted on 150 rheumatoid arthritis patients presenting to the Rheumatology Outpatient Department (OPD) receiving DMARD therapy (approval number AIIMS/IEC/18/160). The patients were followed up for an average of 10.7 weeks and received drugs in four regimens with methotrexate (MTX) (Regimen 1) having the least contribution with a mean of 46.05 Rs, methotrexate + hydroxychloroquine (MTX + HCQ) (Regimen 2) with 174.15 Rs, methotrexate + hydroxychloroquine + leflunomide (MTX + HCQ + Lef) (Regimen 3) with Rs 371.70, and methotrexate + hydroxychloroquine + leflunomide + biological DMARD adalimumab (MTX + HCQ + Lef + bDMARD adalimumab) (Regimen 4) with 17,349.4 Rs. The cost of drug therapy was assessed by calculating the cost of therapy per month for each patient, and adherence was assessed using the Morisky-Green-Levine Scale (MGLS) at the follow-up visit. Results The overall mean cost of DMARD treatment was 205.81 Rs. The overall DMARD therapy cost-effectiveness was Rs 878.14 for a unit change of Disease Activity Score (DAS28). The most cost-effective treatment came out to be Regimen 1 with the least cost of 290.9 Rs for a unit change of DAS28, and the least cost-effective was Regimen 4 with 65,661.8 Rs for a unit change of DAS28. At follow-up, among all subjects of the study, 49 (32.7%) subjects showed high adherence, 71 (47.3%) subjects showed medium adherence, and 30 (20%) subjects showed low adherence. Accordingly, the maximum number of participants fell in the category of medium adherence, i.e., 71 (47.4%). Conclusion Our study concluded that the cost burden varied according to the number of DMARDs being given to the patient. The double-drug therapy of methotrexate + hydroxychloroquine had a maximum "high adherence." On a whole, the majority of patients had "medium adherence" to therapy.

Abstract
The main objective of the study was to perform the pharmacoeconomic analysis of synthetic disease-modifying anti-rheumatic drugs in rheumatoid arthritis patients. A prospective, observational study was conducted in 98 rheumatoid arthritis (RA) patients meeting 2010 Rheumatoid Arthritis Classification Criteria. Treatment-naive RA patients were initiated on synthetic disease-modifying anti-rheumatic drugs (DMARD/s) and followed up for 3 months. Average cost-effectiveness analysis was done by taking Health Assessment Questionnaire Disability Index (HAQ-DI) score as a measure of effectiveness. Out of the 98 RA patients, 15.30% were males and 84.69% females. 80.61% RA patients are seropositive. Majority of the study population patients (55%) were on combination of three synthetic DMARDs and almost a quarter (24.48%) were on combination of two synthetic DMARDs. The mean value of DAS 28 at baseline was 6.07 ± 1.33 and after 3 months treatment, the mean was 3.84 ± 1.11. The mean disability index measured by HAQ-DI was significantly reduced from 1.43 ± 0.71 to 0.81 ± 0.61, p < 0.001, after 3 months treatment. The direct medical cost of treatment of RA per month is 997.05 rupees. The average cost-effectiveness ratio of combination of synthetic DMARDs was 1533.92 rupees. Treatment of RA with synthetic DMARDs controls disease activity and improves disability with reasonable cost of treatment. The majority of the direct medical cost is attributable to cost of medicine and laboratory investigation. Use of quality generic drugs and an early diagnosis would minimize the economic burden on the patient.

Impact of Adalimumab on Work Productivity and Activity Impairment in Japanese Patients with Rheumatoid Arthritis: Large-Scale, Prospective, Single-Cohort ANOUVEAU Study. Adv Ther 2017; 34:686-702. [PMID: 28144917 PMCID: PMC5350205 DOI: 10.1007/s12325-017-0477-z] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2016] [Indexed: 02/03/2023]
Abstract
INTRODUCTION The Adalimumab Non-interventional Trial for Up-verified Effects and Utility (ANOUVEAU) was a large-scale, multicenter, prospective, observational, single-cohort study that evaluated the effects of adalimumab (ADA) on rheumatoid arthritis (RA)-related work productivity and activity impairment (RA-related WPAI) and disease activity in routine rheumatology care in Japan. METHODS Patients with RA were categorized as paid workers (PWs, ≥35 h/week), part-time workers (PTWs, <35 h/week), or homemakers (HMs, unemployed) and were administered the WPAI for RA (WPAI/RA) questionnaire. All patients who received ADA were followed for 48 weeks to evaluate safety and effectiveness. RESULTS Of the 1808 patients analyzed, 825, 243, and 740 patients were PWs, PTWs, and HMs, respectively. WPAI/RA domain scores significantly improved at weeks 12, 24, and 48 in all groups, with maximum improvement observed for PWs (p < 0.05). Additionally, remission rates (according to Disease Activity Score 28, erythrocyte sedimentation rate, Simplified Disease Activity Index, or Health Assessment Questionnaire-Disability Index scores) and EuroQol 5-Dimension 3-Level scores significantly increased from baseline to 48 weeks in all groups (p < 0.0001). Analysis of patient subgroups revealed better WPAI/RA outcomes for patients who were biologic-naïve, treated with concomitant methotrexate, or with RA duration of ≤2 years (p < 0.05). The rate of serious adverse events over 48 weeks of ADA treatment was 5.23%. CONCLUSIONS Treatment with ADA provided sustained improvement in WPAI and had an acceptable safety profile in patients with RA. FUNDING AbbVie GK and Eisai Co., Ltd.

Abstract
Functional disability is a major concern in patients with rheumatoid arthritis (RA). This retrospective study investigated the risk factors for vertebral fractures (VFs) in postmenopausal RA patients and determined the impact of VFs on functional status. Data from a cohort of 200 postmenopausal RA patients in a single hospital registry were analyzed. Demographic and clinical data, imaging data from spine radiographs, and bone mineral density (BMD) data were collected from the patients at baseline and at the final visit (a mean of 2.9 years after the first visit). Risk factors for incident VFs and their impact on the modified health assessment questionnaire (mHAQ) were analyzed. Twenty-eight patients (14%) developed new VFs (NVFs). Logistic regression analysis adjusted for age, BMI, and disease duration revealed that daily dose of prednisolone, femoral neck BMD, use of active vitamin D3, and use of a bisphosphonate at baseline were factors associated with NVF, with odds ratios (95% confidence interval) of 1.27 (1.05-1.54), 0.94 (0.91-0.97), 0.34 (0.13-0.89), and 0.31 (0.12-0.82), respectively. Patients with NVF exhibited worse mHAQ scores and a greater increase in mHAQ scores from baseline compared with those without NVF. In conclusion, incident VFs were associated with reduced functional status in postmenopausal patients with RA. It is important to prevent VFs to maintain the functional status of RA patients.

Abstract
OBJECTIVES We aimed to assess the efficacy of tacrolimus (TAC) as an add-on therapy in patients with rheumatoid arthritis (RA) who were previously treated with methotrexate (MTX) but not with biologics. METHODS The study group (MTX + TAC group) consisted of 157 patients (selected from among the patients in the Institute of Rheumatology, Rheumatoid Arthritis [IORRA] RA cohort from April 2005 to October 2009) who received add-on therapy with TAC in addition to MTX, but without biologics. A propensity score (PS) for the use of TAC was derived, and 471 PS-matched patients who received MTX alone or MTX with other non-biologic disease-modifying antirheumatic drugs (except for TAC), but not with biologics, were selected and served as the control group. Changes in disease activity in the two groups during three consecutive IORRA phases were analyzed by adjusting for confounding factors. RESULTS The median 28-joint disease activity score (DAS28) decreased from 4.58 to 3.70 in the MTX + TAC group and from 4.12 to 3.61 in the control group. After adjusting for confounding factors, the decrease in the DAS28 score in the MTX + TAC group was significantly larger (by 0.273 points) than that in the control group (P < 0.05). CONCLUSION This study demonstrated the efficacy of add-on therapy with TAC to MTX in patients with RA in daily practice.

Abstract
OBJECTIVES Our goal was to determine the annual direct medical and nonmedical costs for the care of patients with rheumatoid arthritis (RA) using data from a large cohort database in Japan. METHODS Direct medical costs [out of pocket to hospitals and pharmacies and for complementary and alternative medicine (CAM)] and nonmedical costs (caregiving, transportation, self-help devices, house modifications) were determined for RA patients who were participants in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) studies conducted in October 2007 and April 2008. Correlations between these costs and RA disease activity, disability level, and quality of life (QOL) were assessed. RESULTS Data were analyzed from 5,204 and 5,265 RA patients in October 2007 and April 2008, respectively. The annual direct medical costs were JPY132,000 [out of pocket to hospital (US$1 = JPY90 in 2007)], JPY84,000 (out of pocket to pharmacy), and JPY146,000 (CAM). Annual direct nonmedical costs were JPY105,000 (caregiving), JPY22,000 (transportation), JPY30,000 (self-help devices), and JPY188,000 (house modifications). Based on the utilization rate for each cost component, the annual medical and nonmedical costs for each RA patient were JPY262,136 and JPY61,441, respectively. Costs increased with increasing RA disease activity and disability level or worsening quality of life (QOL). CONCLUSIONS Based on the IORRA database, patients with RA bear heavy economic burdens that increase as the disease is exacerbated. The results also suggest that the increase in medical and nonmedical costs may be ameliorated by the proactive control of disease activity.

Abstract
The maximum dosage of methotrexate (MTX) for treatment of rheumatoid arthritis (RA) formally approved in Japan is 8 mg/week. We intended to examine the efficacy and safety of MTX at dosages over 8 mg/week in Japanese rheumatoid arthritis patients using the large Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort database. Among 9,122 patients registered in the IORRA database from the October 2000 survey to the October 2007 survey, 5,201 patients who had been treated with MTX were selected. We attempted to overcome the drawbacks innate to nonrandomized studies by using longitudinal analyses and multifactorial logistic regression analyses. Cross-sectional analysis of data obtained from the October 2007 survey indicated that dosages of MTX higher than 8 mg/week were used in 27.5% of patients treated with MTX. Longitudinal analyses based on data from three consecutive phases showed that final Disease Activity Score-28 (DAS28) values were significantly lower [n = 260, mean difference 0.563, 95% confidence interval (CI) 0.438-0.688, P < 2.2 × 10(-22), two-sided paired t test] than initial values when MTX was increased from 8 mg/week or lower to over 8 mg/week. In addition, longitudinal analyses based on data from two consecutive phases indicated decreases in DAS28 values of 0.26 ± 1.04 (n = 690, P = 6.78 × 10(-11), two-sided paired t test) when MTX dosages were increased from 8 mg/week or lower to over 8 mg/week, compared with decreases of 0.07 ± 0.89 (n = 2,125, P = 0.000307) when the dosage was maintained at 8 mg/week. The decreases in DAS28 values were significantly larger in the former than the latter (P = 2.27 × 10(-6), two-sided unpaired t test). Concerning safety of MTX at dosages over 8 mg/week, we performed logistic regression analysis in which the objective variable was the existence or nonexistence of self-reported side-effects and the explanatory variable was the MTX dosage in the former phase, with adjustments made for age, sex, body mass index (BMI), steroid administration, folic acid administration, concomitant pulmonary diseases, and renal dysfunction. The results indicated that MTX dosages over 8 mg/week did not have any association with either severe or severe + moderate side-effects. These data regarding both efficacy and safety of MTX at dosages over 8 mg/week in Japanese RA patients would provide the basis for use of the drug at dosages currently not formally approved by the Japanese government.

Abstract
The aim of this report was to review the use of orthopedic surgeries performed to manage rheumatoid arthritis (RA). Our review of studies published in English indicates that there has been a decrease in RA-associated surgeries in Western countries. Improvements in medical treatment may partly explain the reduction in numbers of orthopedic joint surgeries, which also suggests a worldwide trend toward improved long-term outcomes. However, the results of our multicenter study in Japan indicate that the number of RA-associated operations has not decreased, and that the numbers of operations performed annually have been relatively stable from 1998 to 2008. Although there definitely has been a decline in the numbers of synovectomy surgeries, the numbers of operations on the upper limbs and foot arthroplasties have increased. With the trend toward milder disease because of improved medical treatment, we speculate that RA patients may want and need better function for the activities of daily living. The combination of medical treatment and surgical intervention is thought to improve outcomes in RA patients who will develop joint destruction. Additional studies, including analyses of RA databases containing long-term data on a variety of surgical interventions, are needed.

Abstract
Although rheumatoid arthritis causes significant disability for more than 1 million individuals in the United States, prior research regarding surgical treatment options has been limited by study sample size, study design, and methods of comparison. Furthermore, there is wide variation in the referral pattern for hand surgery consideration and type of surgical treatment of rheumatoid hand disease, yet the reasons for these differences are unclear. This review describes the role of outcomes research in rheumatoid hand disease by summarizing variations in surgical treatment, detailing current outcome assessment strategies, and offering potential strategies for designing future studies for rheumatoid hand disease.

Abstract
The objective of this study is to determine the incidence of falls and fear of falling by gender and age in Japanese patients with rheumatoid arthritis (RA). Among the Japanese patients who participated in a single-institute-based prospective observational cohort study of patients with RA, namely the Institute of Rheumatology Rheumatoid Arthritis, 765 men (median age 63 years) and 4,231 women (median age 60 years) with RA responded to questions related to falls. Eight percent of men and 11% of women reported one or more falls during the previous 6 months. At least one fall and multiple falls were significantly more frequent in men (p < 0.05) and in women (p < 0.001) with RA over age 65 and age 75 years, respectively, although there was no significant linear increase in risk with age. Sixteen percent of men and 22% of women reported fear of falling. More men over age 65 tended to report fear of falling than those under age 65 (p < 0.001), although the incidence of women with fear of falling increased with advancing age. Japanese patients with RA over age 65 and age 75 appeared to have a high risk of at least one fall and multiple falls, respectively.
