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.

Background and Objectives: The objective of this study was to evaluate the prevalence, clinicopathologic features, and outcome of renal involvement in a large cohort of patients with primary antiphospholipid syndrome (PAPS)., Design, Setting, Participants, & Measurements: We retrospectively examined medical records of 160 patients with a diagnosis of PAPS of two general hospitals of northern Italy between 1985 and 2008., Results: There were 140 women and 20 men. Mean age was 35+/-12 yr. PAPS was characterized by thrombotic events in 41.2%, fetal loss in 39.4%, and both in 19.4%. Signs of renal abnormalities were present in 14 (8.7%) patients. All patients had proteinuria, in the nephrotic range in five; four patients had moderate chronic renal insufficiency, and one had end-stage kidney disease (ESKD). Two patients presented with acute renal failure and one with nephritic syndrome. Ten patients underwent a renal biopsy, which showed a membranous glomerulonephritis in four, proliferative glomerulonephritis in two, thrombotic microangiopathy in two, and vascular lesions consistent with chronic antiphospholipid antibodies nephropathy in two. Patients with renal involvement were older (41.8 versus 34.3 years; P=0.0269), more frequently lupus anticoagulant positive (92.3 versus 48.9%; P=0.0068), and had hypocomplementemia (P<0.05)., Conclusions: Renal abnormalities are present in approximately 9% of patients with PAPS. In addition to APS nephropathy, the prevailing picture is membranous nephropathy. Outcome and long-term follow-up usually are good. Not all of the clinical manifestations of PAPS can be ascribed to thrombotic mechanisms. The heterogeneity of renal involvement confirms the presence of a continuum between systemic lupus erythematosus and PAPS.

The titre of anti-Ro/SSA were analysed by ELISA. Four patients were diagnosed as overlap RA/SS., Results: Six female patients (mean age 58 ys, SD 9.8 ys), with long-standing RA (mean 7 ys, range 5-22 ys) were treated with anti-TNFalpha 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 < 0.006) with stability of sicca symptoms. The titer of ANA and anti-Ro/SSA was stable, while 4 subjects developed anti-dsDNA at low titer within 6-12 months. One patient withdrawn the treatment, because of lupus-like features; another one, with HCV hepatitis, interrupted Etanercept because of elevation of liver enzymes. No anticardiolipin or antibeta2GPI antibodies were detected. One subject with RA-SS also presented a primary biliary cirrhosis: clinical and histological features of cholangitis remained stable during Etanercept treatment., Conclusions: Anti-TNFalpha treatment showed good efficacy and safety in anti-Ro/SSA positive patients with RA. Anti-ds-DNA antibodies at low titer appeared in most patients while the onset of lupus-like disease could be considered a rare event also in RA patients with a rich autoimmune repertoire.
