Prednisone plus methotrexate for polymyalgia rheumatica: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Steroids are the standard treatment for polymyalgia rheumatica. The efficacy of the candidate drug methotrexate has not yet been demonstrated in controlled studies. OBJECTIVE: To compare the efficacy and safety of prednisone plus methotrexate and prednisone alone in patients with polymyalgia rheumatica. DESIGN: Multicenter randomized, double-blind, placebo-controlled trial. SETTING: 5 Italian rheumatology clinics. PATIENTS: 72 patients with newly diagnosed polymyalgia rheumatica. MEASUREMENTS: The proportion of patients no longer taking prednisone, the number of flare-ups, and the cumulative prednisone dose after 76 weeks. INTERVENTION: Prednisone dosage (25 mg/d) was tapered to 0 mg/d within 24 weeks and was adjusted if flare-ups occurred. Oral methotrexate (10 mg) or placebo, with folinic acid supplementation (7.5 mg), was given weekly for 48 weeks. RESULTS: Twenty-eight of 32 patients in the methotrexate group and 16 of 30 patients in the placebo group were no longer taking prednisone at 76 weeks (P = 0.003). The risk difference was 34 percentage points (95% CI, 11 to 53 percentage points). Similar results were obtained after adjustment for C-reactive protein level and duration of symptoms in a multivariate model. Fifteen of 32 patients in the methotrexate group and 22 of 30 patients in the placebo group had at least 1 flare-up by the end of follow-up (P = 0.04). The median prednisone dose was 2.1 g in the methotrexate group and 2.97 g in the placebo group (P = 0.03). The rate and severity of adverse events were similar. LIMITATIONS: Follow-up was short, and a high dose of folinic acid and a relatively high starting dosage of prednisone were used. Ten of 72 patients (14%) discontinued treatment or were lost to follow-up. CONCLUSIONS: Prednisone plus methotrexate is associated with shorter prednisone treatment and steroid sparing. It may be useful in patients at high risk for steroid-related toxicity.

Autoantibody profile in rheumatoid arthritis during long-term infliximab treatment.

The aim of the present study was to investigate the effect of long-term infliximab treatment on various autoantibodies in patients with rheumatoid arthritis. Serum samples from 30 consecutive patients, who were prospectively followed during infliximab and methotrexate therapy for refractory rheumatoid arthritis, were tested at baseline and after 30, 54 and 78 weeks. At these points, median values of the Disease Activity Score were 6.38 (interquartile range 5.30-6.75), 3.69 (2.67-4.62), 2.9 (2.39-4.65) and 3.71 (2.62-5.06), respectively. Various autoantibodies were assessed by standard indirect immunofluorescence and/or ELISA. Initially, 50% of patients were positive for antinuclear antibodies, and this figure increased to 80% after 78 weeks (P = 0.029). A less marked, similar increase was found for IgG and IgM anticardiolipin antibody titre, whereas the frequency of anti-double-stranded DNA antibodies (by ELISA) exhibited a transient rise (up to 16.7%) at 54 weeks and dropped to 0% at 78 weeks. Antibodies to proteinase-3 and myeloperoxidase were not detected. The proportion of patients who were positive for rheumatoid factor (RF) was similar at baseline and at 78 weeks (87% and 80%, respectively). However, the median RF titre exhibited a progressive reduction from 128 IU/ml (interquartile range 47-290 IU/ml) to 53 IU/ml (18-106 IU/ml). Anti-cyclic citrullinated peptide (CCP) antibodies were found in 83% of patients before therapy; anti-CCP antibody titre significantly decreased at 30 weeks but returned to baseline thereafter. In conclusion, the presence of anti-double-stranded DNA antibodies is a transient phenomenon, despite a stable increase in antinuclear and anticardiolipin antibodies. Also, the evolution of RF titres and that of anti-CCP antibody titres differed during long-term infliximab therapy.

Rheumatoid arthritis in beta-thalassemic trait: clinical, serologic and immunogenetic profile.

OBJECTIVES: To investigate the clinical, serologic, radiologic and immunogenetic characteristics of rheumatoid arthritis (RA) occurring in patients with beta-thalassemic trait as compared with RA in control patients from the same geographical area. MATERIALS AND METHODS: Twenty-eight patients with beta-thalassemic trait fulfilling the American College of Rheumatology (ACR) criteria for RA were compared with a control group of twenty-eight RA patients matched for age, sex, disease duration and place of birth. Clinical and routine laboratory assessment, including anti-keratin antibodies and anti-citrullinated peptide antibodies, was carried out in the two groups. The patients were also evaluated for HLADRB1 alleles and radiologic damage. RESULTS: No differences were found with regard to clinical indexes of disease activity, laboratory parameters, and joint erosions. The immunogenetic analysis did not show any significant difference, the percentage of patients with alleles encoding for the shared epitope being similar in the two groups (61% vs. 57%). As for the extra-articular features, we found a trend for a lower prevalence of sicca syndrome in the beta-thalassemic group (14% vs. 39%; P = 0.06). Rheumatoid nodules were not found in beta-thalassemic patients while they were present in two RA patients in the control group. CONCLUSIONS: The chronic polyarthritis occurring in beta-thalassemic trait carriers can be regarded as a true RA similar to that found in Mediterranean countries, possibly characterized by a low prevalence of extra-articular features.

BAL cytokine profile in different interstitial lung diseases: a focus on systemic sclerosis.

BACKGROUND AND AIM: Fibrosing alveolitis develops in up to 80% of systemic sclerosis patients (SSc) but progression to end stage fibrosis occurs in about 15% of cases. Mechanisms leading to the process remain mostly unknown. We compared cytokine profiles of broncho-alveolar lavage fluids (BAL-f) from patients with SSc associated interstitial lung disease (SSc-ILD) (n. 34), idiopathic pulmonary fibrosis (IPF) (n. 13), stage II sarcoidosis (n. 14) and 9 controls. METHODS: Interleukin (IL) 8, monocyte chemoattractant protein 1 (MCP-1), gamma-interferon (IFN-gamma), IL12, IL18 and IL10 and transforming growth factor-beta (TGF-beta) were assessed by ELISA in concentrated BAL-f. RESULTS: Levels of IL8 and MCP-1 were significantly elevated in SSc-ILD and in IPF as compared with controls (Mann Whitney test p < 0.05), while MCP-1 values were significantly lower in SSc-ILD than in IPF. A significant correlation between neutrophils and IL8 levels (p = 0.047), as well as between eosinophils and MCP-1 levels (p = 0.004) was also observed. IFN-gamma levels were slightly higher than normal only in sarcoidosis (p = 0.06), whereas IL12 levels increased both in sarcoidosis and SSc-ILD (p < 0.05). No differences were found in IL18 and TGF-beta levels. Finally, IL10 levels were higher in SSc-ILD and sarcoidosis than in controls and IPF (p < 0.05). CONCLUSION: BAL-f cytokine profile differentiates ILD associated with SSc from IPF. The lower expression of MCP-1 and the higher expression of the anti-fibrotic IL12 and the anti-inflammatory IL10, observed both in sarcoidosis and in SSc-ILD, could account for the better prognosis of these ILDs. Further longitudinal studies are required to confirm whether a different cytokine phenotype may be considered predictive of clinical outcome in SSc-ILD.

Inflammatory myopathy in a patient with cutaneous findings of pityriasis rubra pilaris: a case of Wong's dermatomyositis.

We report the case of a 46-year-old woman presenting cutaneous lesions similar to those of pityriasis rubra pilaris, characterized by diffuse scaling erythroderma and palmoplantar keratoderma; skin biopsy showed follicular hyperkeratosis with a perivascular lymphocytic infiltrate. One year later she developed an inflammatory myopathy; on the basis of clinical features, a diagnosis of dermatomyositis was made. Treatment with prednisone and hydroxychloroquine led to complete control of the cutaneous and muscular involvement, which was maintained during prednisone tapering.
