Objective. To compare the efficacy of a single intraarticular corticosteroid injection, a supervised physiotherapy program, a combination of the two, and placebo in the treatment of adhesive capsulitis of the shoulder.Methods. Ninety-three subjects with adhesive capsulitis of <1 year's duration were randomized to 1 of 4 treatment groups: group 1, corticosteroid injection (triamcinolone hexacetonide 40 mg) performed under fluoroscopic guidance followed by 12 sessions of supervised physiotherapy; group 2, corticosteroid injection alone; group 3, saline injection followed by supervised physiotherapy; or group 4, saline injection alone (placebo group). All subjects were taught a simple home exercise program. Subjects were reassessed after 6 weeks, 3 months, 6 months, and 1 year. The primary outcome measure was improvement in the Shoulder Pain and Disability Index (SPADI) score.Results. At 6 weeks, the total SPADI scores had improved significantly more in groups 1 and 2 compared with groups 3 and 4 (P ‫؍‬ 0.0004). The total range of active and passive motion increased in all groups, with group 1 having significantly greater improvement than the other 3 groups. At 3 months, groups 1 and 2 still showed significantly greater improvement in SPADI scores than group 4. There was no difference between groups 3 and 4 at any of the followup assessments except for greater improvement in the range of shoulder flexion in group 3 at 3 months. At 12 months, all groups had improved to a similar degree with respect to all outcome measures.Conclusion. A single intraarticular injection of corticosteroid administered under fluoroscopy combined with a simple home exercise program is effective in improving shoulder pain and disability in patients with adhesive capsulitis. Adding supervised physiotherapy provides faster improvement in shoulder range of motion. When used alone, supervised physiotherapy is of limited efficacy in the management of adhesive capsulitis.Adhesive capsulitis is a common cause of shoulder pain and disability. It is characterized by spontaneous onset of shoulder pain accompanied by progressive limitation of both active and passive glenohumeral movement (1).

Background: Biologic disease modifying anti-rheumatic drugs (bDMARDs) are recommended for radiographic axial spondyloarthritis (r-axSpA), otherwise known as ankylosing spondylitis, when conventional therapies fail. We report efficacy and safety results of a Phase 3 study of ixekizumab, a high-affinity monoclonal antibody that selectively targets IL-17A, in bDMARDnaïve patients with r-axSpA. Methods: In this randomized, double-blind, Phase 3 study, adult patients with inadequate response/intolerance to NSAIDs, an established diagnosis of r-axSpA, and with radiographic sacroiliitis centrally defined by modified New York criteria and ≥1 spondyloarthritis feature according to Assessment of Spondyloarthritis International Society (ASAS) criteria were recruited from 84 sites (12 countries) in Europe, Asia, and North America. Patients were randomized 1:1:1:1 using a computer-generated random sequence to 80 mg subcutaneous ixekizumab every two (Q2W) or four (Q4W) weeks, 40 mg adalimumab Q2W (active reference arm), or placebo. The primary endpoint was the proportion of patients achieving an ASAS40 response at Week 16. Findings: Between June 20, 2016 and August 22, 2017, 341 patients were randomized to placebo (N=87), adalimumab (N=90), ixekizumab Q2W (N=83), or ixekizumab Q4W (N=81). At Week 16, significantly more patients achieved ASAS40 with ixekizumab Q2W (n=43, 51•8%, p<0•0001), ixekizumab Q4W (n=39, 48•1%, p<0•0001), and adalimumab (n=32, 35•6%; p=0•0053) versus placebo (n=16, 18•4%). One serious infection occurred in each of the ixekizumab Q2W (1•2%), ixekizumab Q4W (1•2%), and adalimumab (1•1%) arms; none were reported with placebo. One (1•1%) Candida infection occurred in the adalimumab arm and one (1•2%) patient receiving ixekizumab Q2W was adjudicated as having probable Crohn's disease. No opportunistic infections, malignancies, or deaths occurred. Interpretation: Each dosing regimen of ixekizumab was superior to placebo for improving r-axSpA signs and symptoms in bDMARD-naïve patients; the safety profile was consistent with previous studies of ixekizumab. The adalimumab control arm performed as expected.

Axial spondyloarthritis (axSpA) is a chronic immune-mediated disease characterized by inflammation of the spine and sacroiliac joint (SIJ), peripheral joint involvement, extra articular manifestations, and a strong genetic association with human leukocyte antigen (HLA)-B27. Radiographic axSpA (r-axSpA) was previously classified as ankylosing spondylitis (AS) in 1984 and updated to r-axSpA as part of the ASAS criteria. Both criteria sets require the same radiographically confirmed structural damage to the sacroiliac joint as well as at least one accompanying clinical element.

ObjectiveTo determine the effect of chondroitin sulphate (CS) treatment on cartilage volume loss, subchondral bone marrow lesions (BML), synovitis and disease symptoms in patients with knee osteoarthritis (OA).MethodsIn this pilot multicentre, randomised, double-blind, controlled trial in primary knee OA, 69 patients with clinical signs of synovitis were randomised to receive CS 800 mg or placebo once daily for 6 months followed by an open-label phase of 6 months in which patients in both groups received CS 800 mg once daily. Cartilage volume and BML were assessed by MRI at baseline and at 6 and 12 months; synovial membrane thickness was assessed at baseline and at 6 months.ResultsThe CS group showed significantly less cartilage volume loss than the placebo group as early as 6 months for the global knee (p=0.030), lateral compartment (p=0.015) and tibial plateaus (p=0.002), with significance persisting at 12 months. Significantly lower BML scores were found for the CS group at 12 months in the lateral compartment (p=0.035) and the lateral femoral condyle (p=0.044). Disease symptoms were similar between the two groups.ConclusionCS treatment significantly reduced the cartilage volume loss in knee OA starting at 6 months of treatment, and BML at 12 months. These findings suggest a joint structure protective effect of CS and provide new in vivo information on its mode of action in knee OA.

BackgroundIn osteoarthritis (OA) treatment, although chondroitin sulfate (CS) was found in a number of studies using radiography to have a structure-modifying effect, to date CS use is still under debate. A clinical study using quantitative magnetic resonance imaging (qMRI) is therefore of the utmost importance. Here we report data from a 24-month, randomised, double-blind, double-dummy, controlled, comparative exploratory study of knee OA. The primary endpoint was to determine the effect of CS 1200 mg/day versus celecoxib 200 mg/day on cartilage volume loss (CVL) in the lateral compartment over time as measured by qMRI. Secondary endpoints included assessment of the OA structural changes and signs and symptoms of OA.MethodsqMRI was performed at baseline and at 12 and 24 months. CVL, bone marrow lesion size, and synovial thickness were evaluated using qMRI. The primary statistical analysis was carried out on the modified intention-to-treat (mITT) population (n = 138) using chi-squared, Fisher’s exact, Wilcoxon Mann–Whitney, and Student’s t tests and analysis of covariance. Analyses were also conducted on the according-to-protocol (ATP; n = 120) population.ResultsIn the adjusted mITT analysis, compared with celecoxib treatment, patients treated with CS had a significant reduced CVL at 24 months in the medial compartment (celecoxib –8.1 % ± 4.2, CS –6.3 % ± 3.2; p = 0.018) and medial condyle (–7.7 % ± 4.7, –5.5 % ± 3.9; p = 0.008); no significant effect was seen in the lateral compartment. In the ATP population, CS reduced CVL in the medial compartment at 12 months (celecoxib –5.6 % ± 3.0, CS –4.5 % ± 2.6; p = 0.049) and 24 months (celecoxib –8.4 % ± 4.2, CS –6.6 % ± 3.3; p = 0.021), and in the medial condyle at 24 months (celocoxib –8.1 % ± 4.7, CS –5.7 % ± 4.0; p = 0.010). A trend towards a statistically reduced synovial thickness (celecoxib +17.96 ± 33.73 mm, CS –0.66 ± 22.72 mm; p = 0.076) in the medial suprapatellar bursa was observed in CS patients. Both groups experienced a marked reduction in the incidence of patients with joint swelling/effusion and in symptoms over time. Data showed similar good safety profiles including cardiovascular adverse events for both drugs.ConclusionThis study demonstrated, for the first time in a 2-year randomised controlled trial using qMRI, the superiority of CS over celecoxib at reducing CVL in knee OA patients.Trial registrationClinicalTrials.gov NCT01354145.
