The efficacy of biological agents has been shown in several randomized clinical trials. However, little is known regarding the performance of these drugs in daily rheumatological care. Totally, 173 patients treated with biological agents (infliximab, etanercept, adalimumab, anakinra) were retrospectively analyzed between November 2001 and December 2005 at an Austrian rheumatic outpatient clinic. In total, 224 courses of treatment with biological agents were followed up. Among the 93 drug discontinuations observed, the most frequent causes were inefficacy (56.5%) and side effects (31.9%). In 74 patients (51%), the first biological agent was withdrawn after a median treatment period of 10.7 (range 0–80) months. A second biological agent was given to 36 patients, a third to 11 and a fourth to 3 patients. Our data underline the necessity of large observational studies to assess the full spectrum of patients treated with biological agents in clinical routine. [ABSTRACT FROM AUTHOR]

This study was conducted to assess the use of the European preliminary criteria, the Breiman-classification tree and the American–European criteria for diagnosis of primary Sjögren’s Syndrome (pSS) in daily practice. A retrospective analysis of 17 consecutive patients with pSS (European criteria) was performed evaluating the application of the Schirmer test, semiquantitative sialoscintigraphy, immunologic tests, including rheumatoid factor, antinuclear antibodies, Sjögren’s syndrome autoantibodies (SS-A, SS-B) and lip biopsy. Out of the 17 patients with pSS according to the European criteria, 15 patients fulfilled the classification tree (=88.2%), and 4 patients fulfilled the American–European criteria (=23.5%, P = 0.001). In the four patients fulfilling the American–European criteria, a positive result of the sialoscintigraphy was not crucial for the diagnosis according to these criteria. In conclusion, the American–European criteria are more stringent than the European preliminary criteria. We assume the role of sialoscintigraphy to be reduced when applying the American–European criteria. [ABSTRACT FROM AUTHOR]

In a case-control study that included a total of 98 patients and 83 controls, the possible link between various pathogens and abdominal aortic aneurysms was investigated. For 68 patients with abdominal aortic aneurysm and age-matched controls, no differences were detected in the levels of immunoglobulin (Ig)A and IgG Chlamydiaceae and Chlamydophila pneumoniae antibodies. Patients with IgA titers positive for Chlamydophila pneumoniae showed progressive disease (defined as an annual increase of the aneurysm diameter of ≥0.5 cm) more frequently than patients with negative IgA titers ( p = 0.046). Polymerase chain reactions performed to detect DNA for Chlamydophila pneumoniae, Chlamydia trachomatis, Chlamydophila psittaci, human cytomegalovirus, Borrelia burgdorferi and Helicobacter pylori in tissue specimens of 30 patients and 15 controls were negative. In summary, Chlamydophila pneumoniae may contribute to aortic aneurysm disease progression, but DNA of this and other pathogens was not found in patients’ specimens. [ABSTRACT FROM AUTHOR]
