Vitamin D in Behcet's Disease, a Brief Review of the Literature.

Behcet's disease is a chronic vasculitis of unknown etiopathogenesis. Serum vitamin D levels have been reported to be associated with a variety of inflammatory and autoimmune diseases one of which is Behcet's disease. The previous studies about vitamin D in Behcet's disease seem to be focused on 4 main categories; the studies evaluating serum vitamin D levels between patients with Behcet's disease and controls, the studies evaluating serum vitamin D in the susceptibility and pathogenesis of Behcet's disease, the studies evaluating serum vitamin D in clinical involvements and activity of Behcet's disease, and the studies evaluating the effect of serum vitamin D replacement in Behcet's disease. The aim of this manuscript was to evaluate the results of the studies on serum vitamin D in Behcet's disease and review the literature.

Endoscopic findings of dyspeptic patients unresponsive to proton pump inhibitors.

OBJECTIVE: To evaluate the endoscopic findings of dyspeptic patients unresponsive to proton pump inhibitors (PPIs) and analyze if there is any correlation between these findings and dyspeptic symptoms via predetermined inquiry. METHODS: Patients between 18 and 45 years of age were selected among those referred to our unit for upper GI endoscopy due to failure to achieve improvement in dyspeptic complaints with PPI. Patients who consent to participate in and eligible for the study were questioned for their symptoms using questionnaires. RESULTS: A total of 446 patients with female preponderance (60%) were included in the study. Endoscopic results were listed as: 147 (32.9%) normal, 16 (3.6%) gastric ulcer, 36 (8.1%) duodenal ulcer, 216 (48.4%) gastritis, 7 (1.5%) duodenitis and 24 (5.4%) esophagitis. A total of 122 patients were classified as functional dyspepsia. While incidence of persistent bloating was distinctly higher in patients with gastritis compared to those with normal endoscopic findings (p:0.000), but its incidence was comparable between ulcer and normal patients. No statistical difference was detected between gastritis, ulcer and normal endoscopy patients considering incidence of early satiety. Compared to those with normal endoscopy patients, incidence of epigastric pain was significantly higher among patients with gastritis and ulcer (p: 0.002 and p: 0.000 respectively). Incidence of heartburn was higher in patients with gastritis compared to those with normal endoscopy findings, but it was similar to those with ulcer. CONCLUSION: Most (67.1%) of the patients between 18 and 45 years of age with no alarm symptoms had diagnoses that required use of a PPI. Hence, the patients should be carefully evaluated before referring for endoscopy.
