The effects of combined spa therapy and rehabilitation on patients with ankylosing spondylitis being treated with TNF inhibitors.

Despite advances in pharmacological therapy, physical treatment continues to be important in the management of ankylosing spondylitis (AS). The objective of the present study was to evaluate the effects and tolerability of combined spa therapy and rehabilitation in a group of AS patients being treated with TNF inhibitors. Thirty AS patients attending the Rheumatology Unit of the University of Padova being treated with TNF inhibitors for at least 3 months were randomized and assessed by an investigator independent from the spa staff: 15 were prescribed 10 sessions of spa therapy (mud packs and thermal baths) and rehabilitation (exercises in a thermal pool) and the other 15 were considered controls. The patients in both groups had been receiving anti-TNF agents for at least three months. The outcome measures utilized were BASFI, BASDAI, BASMI, VAS for back pain and HAQ. The evaluations were performed in all patients at the entry to the study, at the end of the spa treatment, and after 3 and 6 months. Most of the evaluation indices were significantly improved at the end of the spa treatment, as well as at the 3 and 6 months follow-up assessments. No significant alterations in the evaluation indices were found in the control group. Combined spa therapy and rehabilitation caused a clear, long-term clinical improvement in AS patients being treated with TNF inhibitors. Thermal treatment was found to be well tolerated and none of the patients had disease relapse.

Synovial biomarkers in psoriatic arthritis.

OBJECTIVE: To find candidate biomarkers of psoriatic arthritis (PsA). A panel of synovial fluid (SF) and synovial tissue (ST) biomarkers was analyzed in patients with resistant peripheral PsA, in relation to clinical and imaging outcomes of synovitis response following serial intraarticular (IA) etanercept injections (12.5 mg). METHODS: Fourteen PsA patients with resistant knee joint synovitis were treated with 4 IA etanercept injections in a single knee joint, once every 2 weeks. Primary outcome (Thompson's knee index: THOMP) and secondary outcomes were assessed at baseline and end of study: C-reactive protein, Knee Joint Articular Index (KJAI), Health Assessment Questionnaire disability index, maximal synovial thickness (MST) by gray-scale ultrasonography, contrast-enhanced magnetic resonance imaging (C+MRI), ST-cluster differentiation (CD)45+ mononuclear cell, ST-CD31+ vessels, and ST-CD105+ angiogenic endothelial cells, along with levels of SF interleukin 1ß (IL-1ß), IL-1 receptor antagonist (Ra), and IL-6. RESULTS: At the end of the study, clinical and imaging outcomes, ST and SF biological markers were significantly reduced compared to baseline. There was a significant association between IL-6 and either THOMP or KJAI; between either ST-CD31+ or ST-CD105+ or ST-CD45+; between ST and SF biomarkers expression (CD45+ and IL-1ß) and between ST-CD45+ and both KJAI and MRI-MST. Comparing pre- versus post-IA etanercept injection changes (Δ), Δ IL-1ß was significantly correlated with both Δ IL-6 and with Δ IL-1Ra and Δ IL-6 with Δ IL-1Ra. CONCLUSION: The association to disease activity and the changes following IA treatment indicate that ST-CD45+ and ST-CD31+, along with SF-IL-6 and SF-IL-1ß, may represent candidate biomarkers of the knee synovitis response to IA tumor necrosis factor-α blockade.

Anterior chest wall involvement in early stages of spondyloarthritis: advanced diagnostic tools.

OBJECTIVE: Anterior chest wall (ACW) involvement is difficult to evaluate in patients with spondyloarthritis (SpA). Bone scan is sensitive to ACW involvement, while magnetic resonance imaging (MRI) detects early alterations in SpA. We compared the sensitivity and specificity of bone scans and MRI in assessing ACW in early SpA. METHODS: Out of 110 patients with early SpA attending the Outpatient Rheumatology Unit Clinic of Padua University from January 2008 to December 2010, the 40 complaining of pain and/or tenderness [60% with psoriatic arthritis (PsA), 12.5% with ankylosing spondylitis, and 27.5% with undifferentiated SpA] underwent bone scans and MRI. RESULTS: At clinical examination, sternocostoclavicular joints were involved in 87.5% on the right, 77.5% on the left, and 35% on the sternum. Bone scan was positive in 100% and MRI in 62.5% of these patients. Early MRI signs (bone edema, synovial hyperemia) were observed in 27.5%, swelling in 5%, capsular structure thickness in 37.5%, erosions in 15%, bone irregularities in 15%, osteoproductive processes in 12.5%, and osteophytes in 5%. A higher prevalence of Cw6, Cw7, B35, and B38 was found in 15%, 48%, 28%, and 12%, respectively, of the patients with PsA who had bone scans. CONCLUSION: Noted mainly in women, ACW involvement was frequent in early SpA. Both bone scans and MRI are useful in investigating ACW inflammation. Bone scans were found to have high sensitivity in revealing subclinical involvement, but a low specificity. MRI provides useful information for therapeutic decision making because it reveals the type and extent of the process. The significant associations of HLA-Cw6 and Cw7 with PsA could suggest that genetic factors influence ACW involvement.

Rehabilitation treatment in patients with ankylosing spondylitis stabilized with tumor necrosis factor inhibitor therapy: a randomized controlled trial.

OBJECTIVE: To assess the 2- (T1) and 6-month (T2) followup effects on pain, spine mobility, physical function, and disability outcome of a rehabilitation intervention in patients with ankylosing spondylitis (AS) stabilized with tumor necrosis factor (TNF) inhibitor therapy. METHODS: Sixty-two outpatients (49 men, 13 women, mean age 47.5 ± 10.6 yrs) were randomized to rehabilitation plus an educational-behavioral (n = 20) program, to an educational-behavioral program only (n = 20), or to a control group (n = 22). The educational-behavioral program included 2 educational meetings and 12 rehabilitation exercise sessions (stretching, strengthening, chest and spine/hip joint flexibility exercises), which patients then performed at home. Outcome assessment at the end of rehabilitation training (T1) and at T2 was based on spinal pain intensity in the previous 4 weeks by self-report visual analog scale (VAS; 100 mm: 0 = no pain, 100 = maximum pain), BASMI, BASFI, BASDAI, and on chest expansion and the active range of motion of the cervical and lumbar spine measured by a pocket goniometer. RESULTS: The 3 groups were comparable at baseline. On intragroup comparison at T1, the rehabilitation group showed significant improvement in the BASMI and BASDAI, in chest expansion, and in most spinal active range of motion measurements. BASFI and cervical and lumbar VAS scores improved in both the rehabilitation and educational-behavioral groups. The positive results achieved in the rehabilitation group were maintained at the 6-month followup. CONCLUSION: Combining intensive group exercise with an educational-behavioral program can provide promising results in the management of patients with clinically stabilized AS on TNF inhibitor treatment.
