IntroductionPulmonary involvement represents a major cause of death of systemic sclerosis (SSc) patients. Recent data suggest that tyrosine kinase inhibitors, such as imatinib, may be a therapeutic option for SSc patients. However, preliminary published clinical trials were inconclusive about imatinib efficacy and showed side effects. The purpose of this study was to verify efficacy and tolerability of low-dose imatinib on interstitial lung disease in a cohort of SSc patients unresponsive to cyclophosphamide therapy.MethodsThirty consecutive SSc patients with active pulmonary involvement, unresponsive to cyclophosphamide, were treated with imatinib 200 mg/day for 6 months followed by a 6-month follow-up. A “good response” was defined as an increase of forced vital capacity (FVC) by more of 15% and/or increase of diffusing capacity of carbon monoxide (DLCO) >15% and PaO2 > 90% of initial value and high-resolution computed tomography (HRCT)-scan pattern unchanged or improved.ResultsTwenty-six patients completed the study. Three patients died and one patient was lost to follow-up. Four patients (15.32%) had a good response, 7 worsened and 15 had a stabilized lung disease. Overall, 19 (73.07%) patients had an improved or stabilized lung disease. After a 6-month follow-up, 12 (54.5%) of the 22 patients showed an improved or stabilized lung disease.ConclusionsLung function was stabilized in a large proportion of patients unresponsive to cyclophosphamide therapy and a beneficial outcome emerged from the analysis of HRCT lung scans. There was no significant improvement of skin involvement, and the low dose was well tolerated. These data provide useful suggestions to design future randomized clinical trials for SSc therapeutics.Trial registrationClinicalTrials.gov NCT00573326. Registered 13 December 2007.

Anticardiolipin antibodies (aCL) and HLA-DR antigens were determined in 314 central European patients with systemic lupus erythematosus (SLE). Both HLA-DR4 and DR7 were increased in aCL-positive patients, and aCL were significantly associated with DRw53. The association between DRw53 and aCL was also apparent in those 17 patients with SLE and the anticardiolipin syndrome. There was no association between aCL and HLA-DQ or C4 alleles in SLE.

In a multicentre study anticardiolipin antibodies of the IgG and IgM isotypes were measured by a solid phase enzyme immunoassay in 368 patients with systemic lupus erythematosus (SLE) who were not selected on the basis of features of antiphospholipid syndrome. Clinical and laboratory associations of increased levels of anticardiolipin antibodies were evaluated. IgG and IgM antibodies to cardiolipin were documented in 224 (60.9%) and 128 (34.8%) patients, respectively. Regarding the symptoms of antiphospholipid syndrome, elevated amounts of anticardiolipin IgG were significantly associated with spontaneous abortion (P < 0.001), thrombocytopenia (P < 0.01), livedo reticularis (P < 0.01) and a positive direct Coombs test (P < 0.05), but not with thrombosis or central nervous system diseases such as epilepsy and psychosis. IgM antibodies to cardiolipin were associated with a positive direct Coombs test (P < 0.01), but with no other symptom of antiphospholipid syndrome. The predictive values of anticardiolipin antibody determinations in unselected SLE patients were poor for all features of antiphospholipid syndrome because of high proportions of false-positive and false-negative results. As for other manifestations of SLE, positive correlations between raised antibodies to double-stranded DNA and the occurrence of anticardiolipin antibodies of the IgG isotype were observed, and anticardiolipin IgM was negatively associated with nephritis.

Objectives: To assess efficacy and safety of the association oxycodone/acetaminophen (oxycodone/ acetaminophen) for pain treatment and disability improvement in patients with rheumatoid arthritis (RA).Methods: Patients with RA (n = 29), suffering from moderate to severe pain for more than 3 months, were included in the study, except those under RA therapy with biological drugs. The treatment started with oxycodone/acetaminophen at the dosage of 5 mg/325 mg, and then the dosage was titrated until the attainment of good pain relief. Antiemetic and laxative therapy was used for the prophylaxis of known opioid-related adverse events.Results: Patients continued their RA therapy without changing the dosages, reported reduced pain intensity and disease activity, and improvement of disability. Forty-two percent of patients had a good clinical response to oxycodone/acetaminophen treatment, according to European League against Rheumatism (EULAR) assessment criteria, and 50 percent of patients reached the American College of Rheumatology 20 percent improvement criteria (ACR20). At the end of the study, the mean (±SD) daily effective oxycodone/acetaminophen dose was 13.8 (±6.8) mg/720.4 (±291.0) mg. No serious adverse event was observed. Nausea, vomiting, and stipsis of mild-moderate intensity were the most common adverse events.Conclusion: Oxycodone/acetaminophen at low dosages for the treatment of chronic pain in RA patients can be a good alternative to non-steroidal anti-inflammatory drugs (NSAIDs), allowing the reduction of their consumption, while keeping RA therapy stable.
