Efficacy of rehabilitation for patients with ankylosing spondylitis: comparison of a four-week rehabilitation programme in a Mediterranean and a Norwegian setting.

OBJECTIVE: To investigate the sustained effect of a rehabilitation programme for patients with ankylosing spondylitis, and to compare the effect of this intervention given in a Mediterranean vs a Norwegian setting. METHODS: A total of 107 patients with ankylosing spondylitis applying for rehabilitation were randomized to a 4-week inpatient rehabilitation programme in a Mediterranean country or in Norway. The participants were evaluated clinically before and after the rehabilitation period (week 0 and 4) and in week 16. The ASsessments in Ankylosing Spondylitis working group's Improvement Criteria (ASAS-IC), and tests of spinal mobility and physical capacity were used to measure treatment response. RESULTS: An ASAS20 improvement was still present at week 16 in 50% of the patients treated in a Mediterranean and 23% in a Norwegian centre (p = 0.006). The tests of spinal mobility, physical capacity, and almost all patient's assessments of health status (ASAS-IC components) were still improved at week 16 after therapy in both climatic settings. While the improvements in physical capacity were comparable, the spinal mobility and ASAS-IC components improved more, and improvements were sustained longer, after rehabilitation in a Mediterranean setting. CONCLUSION: Patients with ankylosing spondylitis benefit from a 4-week rehabilitation programme in Norway, but even more so from a similar programme in a Mediterranean setting.

Fertility in women with chronic inflammatory arthritides.

OBJECTIVE: To compare fertility rates in women with RA, other chronic arthritides (OCAs) and JIA with reference women from the general population. METHODS: Each woman from a Norwegian patient registry was matched by year of birth with 100 reference women randomly selected from the National Population Registry. Data linkage of patients and references with the Medical Birth Registry of Norway (MBRN) identified all offspring in patients and references until October 2007, and indirectly also nulliparous (childless) women. Groups were compared with Mann-Whitney U-test for continuous variables and chi-squared tests for categorical variables. Poisson regression analysis was applied to calculate relative fertility rates in the diagnostic groups vs references. RESULTS: Among 631 patients 849 children were registered in MBRN. Of these, 289 children (34.0%) were born after time of diagnosis vs 44.3% in references. Altogether, 206 of 631 patients (32.6%) were nulliparous vs 26.4% in references (P < 0.001). Among RA patients, 28.4% (96 of 338) were nulliparous vs 24.5% in references (P = 0.09), 30.7% (67 of 218) in OCA patients vs 24.5% in references (P = 0.03) and 57.3% (43 of 75) in JIA patients vs 40.9% in references (P = 0.004). Adjusted relative fertility rates in RA, OCA and JIA after diagnosis were 0.88, 0.84 and 0.84, respectively, compared with references. CONCLUSION: A higher proportion of women with chronic inflammatory arthritides were nulliparous compared with references, and relative fertility rates were reduced in all patient groups.

The comparative effectiveness of tumor necrosis factor-blocking agents in patients with rheumatoid arthritis and patients with ankylosing spondylitis: a six-month, longitudinal, observational, multicenter study.

OBJECTIVE: To compare the effectiveness of tumor necrosis factor (TNF)-blocking agents (etanercept and infliximab) in patients with rheumatoid arthritis (RA) and patients with ankylosing spondylitis (AS). METHODS: Data from an ongoing longitudinal, observational study in Norway were used to assess changes in health-related quality of life (HRQOL) in patients with RA (n = 291) and AS (n = 62). Patients received anti-TNF therapy, and changes in scores on the Short Form 36 (SF-36), SF-6D, modified Health Assessment Questionnaire, and visual analog scales for patients' assessments of pain, fatigue, and global status from baseline to followup examinations at 3 and 6 months were compared. Data were adjusted for age, sex, and baseline values and are presented as crude estimates as well as standardized response means. RESULTS: Both groups had improvements in all measures at 3 and 6 months. At 3 months, the changes were significantly better in the AS group compared with the RA group for all measures except the SF-36 social functioning scores. At 6 months, all changes were numerically greater in the AS group. Differences were significant for the SF-36 role emotional scores and were borderline significant for the SF-36 physical functioning, role physical, and vitality scores and for the SF-6D scores. CONCLUSION: In this real-life setting, patients with AS experienced improvement in HRQOL that was comparable to, and sometimes greater than, that observed in RA patients. These results support the idea that patients with AS should have the same access to TNF-blocking agents as patients with RA.

[Medical prophylaxis and treatment of steroid induced osteoporosis]. / Medikamentell profylakse og behandling av steroidindusert osteoporose.

BACKGROUND: Glucocorticoid steroids are widely used as antiinflammatory and immunosuppressive medications and are well known to induce osteoporosis. MATERIAL AND METHODS: Randomised clinical trials and Cochrane reports on the use of calcium, vitamin D, bisphosphonates and hormones were reviewed and the results summarised. Additionally, national and some international recommendations were reviewed in order to propose recommendations for prophylaxis and treatment. The literature was identified by Medline searches. RESULTS AND INTERPRETATION: Calcium and vitamin D prevent bone loss in low-to-medium-dose glucocorticoid steroid therapy. Bisphosphonates maintain or modestly increase lumbar and hip bone mass. The fracture risk was not significantly reduced in the spine and the hip. The clinical randomised trials and Cochrane reports conclude that bisphosphonates as well as calcium and vitamin D taken together are effective and the drugs of choice in prevention and treatment.

[Combination therapy in rheumatoid arthritis]. / Kombinasjonsterapi ved revmatoid artritt.

BACKGROUND: During the last decade patients with active rheumatoid arthritis have been offered early and aggressive drug therapy in order to decrease the damaging effect of inflammation on cartilage and bone. Combination of two or more disease-modifying antirheumatic drugs has been used more frequently to achieve better efficacy than with monotherapy without increasing drug side effects. MATERIALS AND METHODS: We have studied available rheumatological literature to find the best documented drug combinations. RESULTS: The combination of methotrexate, sulfasalazine and hydroxychloroquine seems to be a well documented alternative, and so is the combination of methotrexate and cyclosporine. Modern biologic drugs like etanercept, infliximab and anakinra work best in combination with methotrexate. INTERPRETATION: The combination of two or more disease-modifying antirheumatic drugs can be a good alternative to monotherapy in the treatment of patients with active rheumatoid arthritis, either when monotherapy has failed or unacceptable side effects have occurred, or as a first choice in patients who need very early and aggressive therapy. Combination therapy should only be initiated by a rheumatologist, after informed consent. A safe clinical and chemical monitoring must be organized in cooperation with the patient and the primary physician.
