Objective.To establish thresholds for rheumatoid arthritis (RA) activity categories according to the RA Disease Activity Index-5 (RADAI-5).Methods.Three hundred ninety-two patients with RA were categorized according to Disease Activity Score 28-joint count (DAS28), Clinical Disease Activity Index (CDAI), and their satisfaction (PATSAT) with disease status. These measures built the basis for the calculation of disease activity limits for the RADAI-5. Patient assessments simultaneously meeting the identical DAS28, CDAI, and PATSAT categories were taken as the references to establish the thresholds for the respective RADAI-5 categories by calculating the third quartile of the corresponding RADAI-5 values. Subsequently, these new thresholds were applied to all assessments.Results.Seven hundred fifty-eight assessments in 392 patients (2 assessments median/patient) could be obtained, most patients having mild to moderate disease according to DAS28 and CDAI. Calculating the third quartile, the RADAI-5 thresholds were as follows: 0.0–1.4 for a remission-like state, 1.6–3.0 for mild disease activity, 3.2–5.4 for moderate, and 5.6–10.0 for high disease activity. Categorization according to the RADAI-5 showed a normal distribution, while DAS28 and CDAI were somewhat shifted to the left. DAS28 and CDAI levels, as well as tender and swollen joint counts and physician’s global assessment and erythrocyte sedimentation rate, proved to be highly significantly different within the different RADAI-5 categories (Kruskal-Wallis test p < 0.001).Conclusion.RADAI-5 thresholds for RA activity could be elaborated. Patient self-report questionnaires may substitute composite disease activity scores and may contribute significantly to improving documentation in routine patient care.

Objective.We analyzed whether a patient self-report remission criterion, such as that according to the Rheumatoid Arthritis Disease Activity Index-5 (RADAI-5), meets the criteria of the 2011 proposed American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) definition of remission.Methods.The 2 approaches of the ACR/EULAR proposal [Boolean- and Simplified Disease Activity Index (SDAI)-based] as well as the RADAI-5 were used to assess whether patients with RA are in remission. Sensitivity, specificity, positive and negative predictive values (PPV, NPV), and kappa analyses were performed to illustrate the relationship among the different approaches defining remission at a group level.Results.In total, 705 patients' assessments were included. Eighty-nine patients were classified as being in remission according to the Boolean-based and 169 according to the SDAI-based definition of the ACR/EULAR proposals, and 154 according to the RADAI-5. Sixty-eight assessments were classified as being in remission according to all 3 definitions. In the case of RADAI-5 remission, sensitivity was 78%, specificity 86%, PPV 45%, and NPV 96%, indicating remission according to the Boolean-based definition; and 60%, 92%, 66%, and 90%, respectively, indicating remission according to the SDAI-based definition. In the case of remission according to the SDAI-based ACR/EULAR definition, sensitivity was 52%, specificity 100%, PPV 98%, and NPV 87%, also indicating remission according to the Boolean definition; while according to the Boolean definition the values were 98%, 87%, 52%, and 100%, respectively. Kappa statistics showed fair to good agreement for all 3 definitions.Conclusion.Nearly twice as many assessments were classified as being in remission using the SDAI-based or the RADAI-5 definitions when compared to the Boolean-based definition. Remission according to the RADAI-5 also was highly specific for both ACR/EULAR criteria. Sensitivity for the RADAI-5 criterion was even better for the Boolean-based definition than that for the SDAI-based definition.

Objective.Sustained remission in rheumatoid arthritis (RA) results in healthcare utilization cost savings. We evaluated the variation in estimates of savings when different definitions of remission [2011 American College of Rheumatology/European League Against Rheumatism Boolean Definition, Simplified Disease Activity Index (SDAI) ≤ 3.3, Clinical Disease Activity Index (CDAI) ≤ 2.8, and Disease Activity Score-28 (DAS28) ≤ 2.6] are applied.Methods.The annual mean healthcare service utilization costs were estimated from provincial physician billing claims, outpatient visits, and hospitalizations, with linkage to clinical data from the Alberta Biologics Pharmacosurveillance Program (ABioPharm). Cost savings in patients who had a 1-year continuous period of remission were compared to those who did not, using 4 definitions of remission.Results.In 1086 patients, sustained remission rates were 16.1% for DAS28, 8.8% for Boolean, 5.5% for CDAI, and 4.2% for SDAI. The estimated mean annual healthcare cost savings per patient achieving remission (relative to not) were SDAI $1928 (95% CI 592, 3264), DAS28 $1676 (95% CI 987, 2365), and Boolean $1259 (95% CI 417, 2100). The annual savings by CDAI remission per patient were not significant at $423 (95% CI −1757, 2602). For patients in DAS28, Boolean, and SDAI remission, savings were seen both in costs directly related to RA and its comorbidities, and in costs for non-RA-related conditions.Conclusion.The magnitude of the healthcare cost savings varies according to the remission definition used in classifying patient disease status. The highest point estimate for cost savings was observed in patients attaining SDAI remission and the least with the CDAI; confidence intervals for these estimates do overlap. Future pharmacoeconomic analyses should employ all response definitions in assessing the influence of treatment.

Objective.To explore 5 possible criteria for remission in rheumatoid arthritis (RA) based on a patient self-report index, the Routine Assessment of Patient Index Data (RAPID3), with a careful joint examination and possible physician global estimate (DOCGL), but without a formal joint count or laboratory test.Methods.The ESPOIR early RA cohort of 813 French patients recruited in 2002–2005 was analyzed to identify patients in remission 6 months after enrollment, according to 2 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria: Boolean ≤ 1 for total tender joint count-28, swollen joint count-28, C-reactive protein, and patient global estimate (PATGL), and Simplified Disease Activity Index (SDAI) ≤ 3.3. Agreement with 7 other remission criteria was analyzed — Disease Activity Score-28 (DAS28) ≤ 2.6, Clinical Disease Activity Index (CDAI) ≤ 2.8, and 5 candidate criteria based on RAPID3, joint examination, and DOCGL: “RAPID3R” (RAPID3 ≤ 3.0); “RAPID3R+SJ1” (RAPID3 ≤ 3.0, ≤ 1 swollen joint); “RAPID3R+SJ1+D1” (RAPID3 ≤ 3.0, ≤ 1 swollen joint, DOCGL ≤ 1); “RAPID3R+SJ0” (RAPID3 ≤ 3.0, 0 swollen joints); and “RAPID3R+SJ0+D1” (RAPID3 ≤ 3.0, 0 swollen joints, DOCGL ≤ 1), according to kappa statistics, sensitivity, and specificity. Residual global, articular, and questionnaire abnormalities according to each criteria set were analyzed.Results.Among 813 ESPOIR patients, 720 had complete data to compare all 9 possible criteria. Substantial agreement with the Boolean criteria was seen for SDAI, CDAI, RAPID3R+SJ1, RAPID3R+SJ1+D1, RAPID3R+SJ0, and RAPID3R+SJ0+D1 (92.2%–94.7%, kappa 0.67–0.79), versus only moderate agreement for DAS28 or RAPID3R (79.9%–85.8%, kappa 0.46–0.55).Conclusion.Remission according to CDAI and RAPID3R+SJ1, but not DAS28 or RAPID3R, is similar to that of the ACR/EULAR criteria. RAPID3 scores require a complementary careful joint examination for clinical decisions, do not preclude formal joint counts or other indices, and may be useful in busy clinical settings.

Abstract Objectives To evaluate the effectiveness and safety of abatacept over 52 weeks in biologic-naïve rheumatoid arthritis (RA) patients with moderate disease activity in the prospective, 5-year, observational study (ORIGAMI study) in Japan. Methods Abatacept 125 mg was administered subcutaneously once a week. Clinical outcomes included Simplified Disease Activity Index (SDAI) remission at Week 52 (primary endpoint), Japanese Health Assessment Questionnaire (J-HAQ), EuroQol 5-Dimension (EQ-5D), treatment retention, and safety. Results were compared with those of csDMARD controls from the ongoing Institute of Rheumatology, Rheumatoid Arthritis (IORRA) registry. Results Overall, 325 patients were enrolled, with a mean age of 66.9±12.7 years. The proportion of patients achieving SDAI remission (≤3.3) at Week 52 was 18.9% (95% CI: 14.3–23.6) and low disease activity (≤11) was 53.3% (95% CI: 47.4–59.1). A significant improvement was observed in J-HAQ and EQ-5D over 52 weeks in both the abatacept and csDMARD groups. The probability of abatacept treatment retention at Week 52 was 69.9% (95% CI: 64.7–75.5). AEs and serious AEs were reported in 50.0% and 12.1% of patients, respectively. Conclusions Abatacept significantly improved disease activity, physical disability, and quality of life for up to 52 weeks in RA patients in a real-world setting.

Abstract Background Rheumatological complaints including rheumatoid arthritis (RA) are frequently encountered conditions in homeopathy practice. On account of progressive destruction and disability of the joints, and troublesome side effects and dissatisfaction with the mainstream therapies, homeopathy remains one of the most sought-after therapies; however, it remained under-researched systematically. Aim of this trial was to evaluate the possible role of homeopathic treatment in RA by determining changes in severity of complaints and quality of life. Materials and Methods An open observational trial was performed on 50 patients suffering from RA (classified as per 2010 ACR/EULAR criteria) at National Institute of Homoeopathy, Kolkata and were assessed over 4 months of treatment. Disease Activity Score-28 (DAS28) and Rheumatoid Arthritis Disease Activity Index (RADAI) were used as the primary and secondary outcome measures respectively. Individualised medicines were prescribed on the basis of homeopathic principles. Results Six patients dropped out; 44 completed the trial. Intention-to-treat sample (n = 50) was analysed in the end. There were statistically significant reductions in both DAS28 score (6.8 ± 1.0 vs. 6.1 ± 1.2; mean reduction 0.7, 95% CI: 0.4–0.9, p < 0.001) and RADAI score (6.6 ± 1.8 vs. 5.2 ± 1.9; mean reduction 1.4, 95% CI: 1.0–1.9, p < 0.001) over 4 months of individualised homeopathic treatment. Conclusion Individualised homeopathic medicines seemed to produce promising treatment effects by reducing DAS28 and RADAI scores significantly over 4 months. Further randomised trials are warranted with enhanced methodological rigor (Trial registration: CTRI/2017/06/008848).
