Objective: To evaluate the efficacy and the safety of anti-TNF-alfa treatment in elderly patients (≥65 years old) with active rheumatoid arthritis (RA), in comparison with younger (17-65 years old). Methods: We considered retrospectively 295 patients, affected by RA and treated with anti-TNF-alfa drugs. They were divided in two groups, according to their age, and followed up for two years: over-65-years old patients (190) and under-65-years old patients (105). Effectiveness of drugs was assessed analyzing RA disease activity (DAS28, DAS44, SDAI), functional status (HAQ) and serological parameters (CRP) before and after anti-TNF-alfa therapy. Safety was studied considering discontinuation rate of biological disease-modifying antirheumatic drugs, and collateral events rate. Results: At baseline, elderly patients showed higher disease activity’s score (DAS 28, DAS44, SDAI, HAQ) with important loss of articular function (worse quality of life, HAQ) than younger patients (p0.05). Conclusions: Anti-TNF-alfa treatment was efficacious and safe in both groups of patients. These drugs induced improvement in disease activity, apart from the age. No functional improvement was observed in HAQ, showing the irreversible loss of articular function and the incomplete recovery in elderly patients. Age doesn’t interfere with the possibility to treat elderly patients with anti-TNF-alfa drugs.

Objective: To analyse clinical efficacy, onset of new autoantibodies or symptoms of autoimmune disease in patients affected by rheumatoid arthritis with anti-Ro/SSA treated with anti-TNFa agents. Methods: Six anti-Ro/SSA positive subjects with RA were studied every six months until 24th month of treatment in order to detect ANA titer (IFI), anti-dsDNA (Farr), anti-cardiolipin and anti-beta2glycoprotein I (ELISA), anti-ENA (CIE). The titre of anti-Ro/SSA were analysed by ELISA. Four patients were diagnosed as overlap RA/SS. Results: Six female patients (mean age 58ys, SD 9.8ys), with long-standing RA (mean 7ys, range 5-22 ys) were treated with anti-TNFa agents for a mean of 31 months (SD: 20.4 m): 4 with Infliximab and 2 with Etanercept. All the patients showed a significant reduction of DAS until 24th month (p

We studied 99 patients with systemic autoimmune disease (5 males, 94 women; mean age 37 year, range 16-72): 28 Primary Antiphospholipid Syndrome, 67 Systemic lupus Erythematosus, 1 Mixed Connective Tissue Disease, 2 Undifferentiated Connective Tissue Disease and 1 Discoid Lupus. Based on the observation that native PT shows conformational changes in presence of Ca++ ions and discloses new epitopes available for binding with phospholipids, we performed 3 different methods for the detection of aPT in presence and absence of Ca++, finding a different incidence of specific autoantibodies, associated with clinical features of APS (aPT in presence of Ca++) or non associated (aPT in absence of Ca++). The presence of aPT was significantly associated also with the presence of Lupus Anticoagulant (LAC). The detection of aPT (in presence of Ca++) significantly enhances diagnostic sensibility of APS allowing the identification of a subset of patients (6/99) with clinical features of APS, but with negative LAC, aCL and aβ2-GPI; in fact (limited to thrombotic episodes) the sensibility rises from 56.2% with one test (LAC) to 81.1% with the application of LAC, aCL, aβ2GPI and aPT.
