Towards the Lowest Efficacious Dose: Results From a Multicenter Noninferiority Randomized Open-Label Controlled Trial Assessing Tocilizumab or Abatacept Injection Spacing in Rheumatoid Arthritis in Remission.

OBJECTIVE: We assess the clinical and structural impact at two years of progressively spacing tocilizumab (TCZ) or abatacept (ABA) injections versus maintenance at full dose in patients with rheumatoid arthritis in sustained remission. METHODS: This multicenter open-label noninferiority (NI) randomized clinical trial included patients with established rheumatoid arthritis in sustained remission receiving ABA or TCZ at a stable dose. Patients were randomized to treatment maintenance (M) at full dose (M-arm) or progressive injection spacing (S) driven by the Disease Activity Score in 28 joints every 3 months up to biologics discontinuation (S-arm). The primary end point was the evolution of disease activity according to the Disease Activity Score in 44 joints during the 2-year follow-up analyzed per protocol with a linear mixed-effects model, evaluated by an NI test based on the one-sided 95% confidence interval (95% CI) of the slope difference (NI margin 0.25). Other end points were flare incidence and structural damage progression. RESULTS: Overall, 202 of the 233 patients included were considered for per protocol analysis (90 in S-arm and 112 in M-arm). At the end of follow-up, 16.2% of the patients in the S-arm could discontinue their biologic disease-modifying antirheumatic drug, 46.9% tapered the dose and 36.9% returned to a full dose. NI was not demonstrated for the primary outcome, with a slope difference of 0.10 (95% CI 0.10-0.31) between the two arms. NI was not demonstrated for flare incidence (difference 42.6%, 95% CI 30.0-55.1) or rate of structural damage progression at two years (difference 13.9%, 95% CI -6.7 to 34.4). CONCLUSION: The Towards the Lowest Efficacious Dose trial failed to demonstrate NI for the proposed ABA or TCZ tapering strategy.

Factors associated with knowledge and safety skills of arthritis patients receiving biologics: A survey of 677 patients.

OBJECTIVE: We aimed to determine patient and rheumatologist factors associated with the safety skills of patients receiving bDMARDs for inflammatory arthritis. METHODS: Data were obtained from a descriptive observational cross-sectional nationwide survey performed in 2011 in France. Community- and hospital-based rheumatologists were selected at random. The BioSecure questionnaire was used to collect information on patient safety skills. RESULTS: Of the 677 patients included (mean age 53±13years old; 452 (67%) women, 411 (61%) had RA; 421 (64%) received subcutaneous bDMARDs). Patients had received information about their treatments from their physician 610 (90%), a nurse 207 (31%), by a written booklet 398 (59%), and/or during therapeutic patient education (TPE) sessions 99 (15%). The median BioSecure total score was 72/100 (IQR 60-82). In total, 99 (16.4%) patients had a low skill level; 321 (53.2%) a moderate skill level and 183 (30.3%) a high skill level. On multivariate regression analysis, as compared with high safety skills, low skills were associated with living alone (OR 2.8 [95% CI 1.3â¿¿6.0]), low educational level (OR 4.3 [2.1â¿¿8.9]), living in a large city (OR 3.1 [1.2â¿¿8.2]), being unemployed (OR 3.3 [1.6â¿¿6.7]) and not receiving written information, participating in TPE sessions or consulting a nurse (OR 3.8 [1.6â¿¿8.8]). One rheumatologist-related factor was a high number of patients receiving bDMARDs in the practice. CONCLUSION: We reveal factors associated with low safety skills of patients receiving bDMARDs for inflammatory arthritis, which should be addressed to improve safety skills in this population.

Cross-sectional study of self-care safety skills in 677 patients on biodrugs for inflammatory joint disease.

RATIONALE: Biodrugs carry specific risks that patients must be aware of and capable of managing. Until now, few studies have addressed the self-care safety skills of patients taking biodrugs. The primary objective of this study was to describe the self-care safety skills of patients taking biodrugs for chronic inflammatory joint disease. METHODS: We conducted a nationwide cross-sectional survey. To obtain the most representative sample possible of patients taking biodrugs, we selected rheumatologists at random from the directory of the French Society for Rheumatology (SFR). Each rheumatologist was to include 5 consecutive patients receiving biodrugs. The BioSecure questionnaire was used to collect information on patient self-care safety skills. RESULTS: Of the 677 included patients, with a mean age of 53 years, 33% were males, 62% had rheumatoid arthritis, and 47% had previously received a therapeutic patient education (TPE) session. The median BioSecure score (percentage of correctly answered items) was 73% (interquartile range, 60-82). The dimensions with the lowest scores were the symptoms requiring a physician visit (median, 75), vaccinations (median, 75), contraception (median, 50), and subcutaneous biodrugs (median, 68). The replies to theoretical items (assessing knowledge) and those to problem-case items (assessing adaptive skills) were discordant. CONCLUSION: This study provides concrete data of use for improving the information and TPE of patients taking biodrugs. Skills regarding the symptoms that require a physician visit, vaccinations, contraception, and subcutaneous treatments need to be improved. Interesting information can be obtained by simultaneously testing knowledge and coping.

Longitudinal femoral shaft due to bone insufficiency. A review of three cases.

We report three new cases of longitudinal femoral shaft fracture due to bone insufficiency and review the eight cases reported in the literature. The typical patient is a woman older than 65 years of age who present with mechanical pain in the thigh and/or groin. Palpation of the thigh may reproduce the pain. The diagnosis is often made late because the radiographs are normal initially. However, an early and consistent finding is increased radionuclide uptake along the femoral shaft. The fracture line is readily evidenced by computed tomography but may be difficult to see on magnetic resonance imaging. Use of crutches for 6 weeks to protect the bone from weight bearing ensures healing of the fracture.
