Abstract: OBJECTIVE: Infliximab is effective in patients with rheumatoid arthritis (RA). Add-on infliximab therapy in patients on methotrexate results in a rapid gain in effectiveness, which lasts at least 1 year. The objective of this study was to evaluate the effectiveness and continuation rate of infliximab in patients with RA after the first year of treatment. METHODS: The first 50 patients with RA who were given infliximab in the North-Pas-de-Calais region of France were included in a multicenter open-label study. The patients had severe RA or failed to respond to conventional medications. Infliximab was given in a dosage of 3 mg/kg every 8 weeks in combination with methotrexate. Effectiveness was evaluated using the DAS28-3 score and EULAR response criteria. The dates and reasons of infliximab discontinuations were recorded. RESULTS: The 2-year infliximab continuation rate was 70%. Serious adverse events requiring infliximab discontinuation occurred in 7 patients. Mean DAS28-3 scores in the 35 patients who took infliximab for at least 2 years were 6.42 at baseline, 4.33 after 30 weeks, 4.31 after 54 weeks, and 3.86 after 102 weeks. According to EULAR criteria after 102 weeks, there were 12 good responders, 18 moderate responders, and 5 nonresponders. CONCLUSION: Experience acquired in the North-Pas-de-Calais district of France suggests that infliximab is continued for more than 2 years in more than two-thirds of patients and remains effective over this period.

Abstract: OBJECTIVES: To assess the occurrence of bone loss in rheumatoid arthritis (RA) and to determine the factors influencing bone loss (particularly the usefulness of bone turnover markers) over an 18-month period. METHODS: A total of 51 patients were studied, 6 men and 45 females (of whom 35 were menopausal). Their mean age was 56 +/- 10 years and the mean RA duration was 12 +/- 10 years. Twenty-eight (55%) were receiving corticosteroids (10 mg/day for a mean duration of 6 +/- 5 years). Several clinical and biological parameters reflecting disease activity or severity were recorded both at the 0 and 18-month investigations. Bone turnover was assessed at baseline by measuring the serum levels of 4 biological markers. Three of them reflected bone formation, i.e., procollagen type I C-terminal propepeptide (PICP), procollagen type I N-terminal propeptide (PINP) and osteocalcin (OC). The fourth, procollagen type I-C terminal telopeptide (ICTP), reflected bone resorption. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry both at the lumbar spine (LS) and femoral neck (FN) at baseline and 18 months later. RESULTS: Bone loss occurred both at the LS: 2.1%, [95% CI: 0.8%-3.4%, P < 0.005] and femoral neck: 3.1%, [95% CI: 1.1%-5.1%, P < 0.005]. Bone loss was markedly increased for postmenopausal women at the FN: 5.3% [95% CI: 2.9%-7.6%, P < 0.005]. Bone loss was not statistically significantly different between users and non-users of steroids. Bone loss at the LS was significantly correlated with both osteocalcin (r = 0.51, P < 0.01) and ICTP levels (r = 0.32, P < 0.05). FN bone loss was correlated with the osteocalcin level only (r = 0.34, P < 0.05). Fast losers (bone loss at the LS above the median) had higher OC (P < 0.01) and ESR (P < 0.05) levels at baseline as compared with slow losers (bone loss at the LS below the median). CONCLUSION: Bone loss occurs in RA particularly at the FN and seems to be influenced by increased bone turnover and high levels of inflammation.
