Investigation into the upper GI-tract of patients suffering from systemic sclerosis [SSc] and mixed connective tissue disease [MCTD] without symptoms of GI-tract involvement early in the course of the disease to diagnose inflammatory and motility disorders. We retrospectively analysed patients with SSc and MCTD who underwent oesophago-gastro-duodenoscopy [OGD] within a year of the first diagnosis. Patients with a Rodnan skin score above 5, proton pump inhibitors and treatment regimes potentially harmful to the mucosa of the upper GI-tract were excluded. Mucosal damage of the oesophagus was classified according to the Los Angeles Classification. Oesophageal dysmotility was assessed during OGD and confirmed by video cineradiography. A total of thirteen patients with SSc and six with MCTD fulfilled the inclusion criteria. OGD revealed reflux-oesophagitis in 77%, dysmotility of the distal oesophagus in 85%, gastritis in 92% [31% erosive gastritis] and Helicobacter pylori positivity in 38% of our patients suffering from SSc. Patients with MCTD showed features of reflux-oesophagitis, dysmotility of the distal oesophagus, gastritis and dysmotility of the stomach in 0.6%. In all thirteen patients with SSc, significant pathology of the upper GI-tract was found. The results of this study might indicate that OGD should be performed early in patients diagnosed with SSc, even if they do not report typical symptoms. An early diagnose of GI involvement might be followed by an effective therapy and therefore subsequently may improve the prognosis.

Adult-onset Still's disease (AOSD) is empirically treated with nonsteroidal anti-inflammatory drugs, corticosteroids, conventional disease-modifying antirheumatic drugs, tumor necrosis factor-blocking agents or anakinra. The monoclonal anti-interleukin (IL)-6 antibody tocilicumab (TOC) has recently been approved for the treatment of rheumatoid arthritis and may be an attractive therapeutic option for AOSD as well. We report two AOSD patients treated with TOC and review of the current data on the use of TOC in AOSD. TOC was applied to the first patient after failure of cloroquin, methotrexate, adalimumab and etanercept. The second patient received TOC because of inefficacious methotrexate treatment. TOC was well tolerated by both the patients, and no clinically significant side effects occurred. Including these two cases, a total of seven AOSD patients have been successfully treated with TOC so far. TOC may be a promising treatment option for AOSD patients refractory to conventional disease-modifying antirheumatic drugs anakinra and tumor necrosis factor-[Formula: see text].

The prevalence of chronic diarrhea within the U.S. population has been reported to be as high as five per cent, and numerous causes have been identified. Especially in patients suffering from rheumatoid arthritis drug therapy should be considered as possible cause. We report a case of chronic diarrhea triggered by mastocytic enterocolitis in a patient suffering from rheumatoid arthritis. Systemic mastocytosis and other causes of chronic diarrhea, especially therapy with methotrexate, were carefully ruled out. Treatment with desloratadin and ranitidine was initiated and led to a rapid and persistent amelioration of clinical symptoms. The diagnosis of mastocytic enterocolitis should be considered in patients with chronic diarrhea and normal clinical, laboratory, as well as endoscopical work-up.

Introduction: Leukocytoclastic vasculitis (LV) is a necrotising vasculitis of the small dermal blood vessels, clinically presented as palpable purpura. It is a heterogeneous disorder often limited to the skin but which may involve other organs. LV might be a serious drug reaction, caused by bacterial and viral infections, or less commonly a manifestation of systemic vasculitic syndromes.
