    OBJECTIVE: To compare the effects of alendronate and alfacalcidol in the prevention ofglucocorticoid-related osteoporosis in patients with a rheumatic disease. DESIGN: Randomised, double-blind, double-placebo clinical trial (www. clinicaltrials.gov; number: NCT00138983). METHODS: A total of 201 patients with rheumatic disease who were starting glucocorticoid treatment at a daily dose that was equivalent to at least 7.5 mg of prednisone were randomised to alendronate (10 mg) and a placebo capsule ofalfacalcidol daily (n = 100) or alfacalcidol (1 microg) and a placebo tablet ofalendronate daily (n = 101) for 18 months. Primary outcome was change in lumbar spine bone mineral density at 18 months. The main secondary outcome was the incidence of morphometrically confirmed vertebral deformities. RESULTS: Overall, 163 patients completed the study. The bone mineral density of the lumbar spine increased by 2.1% (95% CI: 1.1-3.1) in the alendronate group and decreased by 1.9% (95% CI: -3.I--0.7) in the alfacalcidol group. At 18 months the mean difference in change in bone mineral density between the two groups was 4.0% (95% CI: 2.4-5-5). Three patients in the alendronate group had a new vertebral deformity, compared with 8 patients in the alfacalcidol group, including 5 symptomatic vertebral fractures in 3 patients; the hazard ratio was 0.4 (95% CI: 0.1-1.4). CONCLUSION: Alendronate was more effective than alfacalcidol in preventing glucocorticoid-induced bone loss during this 18-month trial in patients with rheumatic diseases who were starting glucocorticoid treatment

    Objectives: To identify early predictors of stenosing tenosynovitis in the hand and hand-related activity limitations in patients with rheumatoid arthritis (RA). Design: A longitudinal study of an inception cohort. Setting: A large outpatient clinic. Participants: Consecutive patients who attended the Early Arthritis Clinic for at least 2 years and fulfilled the American College of Rheumatology criteria for RA at baseline and/or at the 1-year follow-up were invited to participate until 200 patients were included. Interventions: Not applicable. Main Outcome Measures: Stenosing tenosynovitis, assessed by means of a standardized physical examination. Hand-related activity limitations, assessed with the Disabilities of Arm, Shoulder and Hand questionnaire (DASH). A DASH score above the upper limit of the 95% range of the normative score was defined as abnormal. Prognostic factors: demographic and disease activity-related variables, radiographic damage, the Health Assessment Questionnaire (HAQ) total score and category scores at the 2-year follow-up. Results: The mean age +/- SD of the patients was 59.7 +/- 10.7 years (75% female). The mean time +/- SD between the 2-year follow-up and the assessment of the dependent variables was 3.9 +/- 2.7 years. Stenosing tenosynovitis was present in 33%. The median (interquartile range) DASH score was 26.7 (10.8-42.5); 30% were abnormal. Stenosing tenosynovitis was predicted by the HAQ subscale regarding the use of hands (HAQ-hand) at the 2-year follow-up (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.2-4.2). Hand-related activity limitations were predicted by the Disease Activity Score in 28 joints (OR, 1.8; 95% Cl, 1.3-2.4) and HAQ-hand (OR, 2.4; 95% CI, 1.3-5.8) at the 2-year follow-up. Conclusions: Stenosing tenosynovitis in patients with RA was predicted by HAQ-hand at the 2-year follow-up, and hand-related activity limitations were predicted by disease activity and HAQ-hand at the 2-year follow-up.

    Pulmonary arterial hypertension in limited cutaneous systemic sclerosis: a distinctive vasculopathy.

    Contains fulltext : 81797.pdf (publisher's version ) (Closed access)Systemic sclerosis-associated pulmonary arterial hypertension (SScPAH) has a worse prognosis and response to pulmonary arterial hypertension (PAH) therapy than idiopathic PAH (IPAH). These differences have not yet been explained. Knowledge concerning histological pulmonary vasculopathy in SScPAH is limited in contrast to IPAH. Therefore, we explored patterns of vasculopathy in SScPAH compared with IPAH. Parameters of vasculopathy were assessed from lung tissue of eight PAH patients with limited cutaneous systemic sclerosis and 11 IPAH patients. Lung tissue was obtained at autopsy (n = 15), explantation (n = 3) and biopsy (n = 1). Pulmonary arterial/arteriolar intimal fibrosis was identified in all SScPAH patients and in three IPAH patients (p = 0.003). Fibrosis of pulmonary veins/venules was found in all SScPAH patients and in three IPAH patients (p = 0.003). In four SScPAH patients, fibrosis of veins/venules was focal and associated with capillary congestion as in pulmonary veno-occlusive disease (PVOD). Of the IPAH patients, 10 had unequivocal evidence of plexogenic arteriopathy compared with none of the SScPAH patients (p = 0.001). SScPAH is characterised by small vessel intimal fibrosis, which is associated with a PVOD-like pattern in some cases. This might explain its different clinical behaviour from IPAH. Small vessel intimal fibrosis may provide clues to elucidation of differences in pathogenetic mechanisms between the groups
