Background/Aims: The aim of this study was to evaluate the eradication rate of a triple therapy regimen that included a proton pump inhibitor, amoxicillin, and tetracycline instead of clarithromycin in treatment-naïve patients and in patients who did not respond to standard triple therapy. Methods: This study included 110 patients infected with Helicobacter pylori. Patients in groups A and B were treatment-naïve, and those in group C were not responsive to previous standard triple therapy. Patients in group A (n=40) received lansoprazole 30 mg b.i.d., amoxicillin 1,000 mg b.i.d., and clarithromycin 500 mg b.i.d. for 14 days. Patients in groups B (n=40) and C (n=30) received lansoprazole 30 mg b.i.d., amoxicillin 1,000 mg b.i.d., and tetracycline 500 mg q.i.d. for 14 days. Results: In group A, eradication was achieved in 18 (45%) of the 40 patients included in the intention-to-treat (ITT) analysis and in 18 (47.4%) of the 38 patients included in the per-protocol (PP) analysis. In group B, eradication was achieved in 15 (37.5%) of the 40 patients included in the ITT analysis and in 15 (39.3%) of the 38 patients included in the PP analysis. In group C, eradication was achieved in 14 (46.6%) of the 30 patients included in the ITT analysis and in 14 (43.8%) of the 29 patients included in the PP analysis. There was no statistically signifi cant difference among the 3 groups with regard to eradication rates (p>0.05). Conclusions: Despite the low rate of resistance to tetracycline, the combination of lansoprazole, amoxicillin, and tetracycline instead of clarithromycin is not a good option for the eradication of H. pylori.

Red Cell Distribution Width: A Novel Marker of Activity in Infl ammatory Bowel Disease

Background/Aims: Studies concerning red cell distribution width (RDW) for use in the assessment of infl ammatory bowel disease (IBD) activity are limited. We investigated whether RDW is a marker of active disease in patients with IBD. Methods: In total, 61 patients with ulcerative colitis (UC)and 56 patients with Crohn’s disease (CD) were enrolled in the study group, and 44 age- and-sex-matched healthy volunteers were included as the control group. A CD activity index >150 in patients with CD indicated active disease. Patients with moderate and severe disease based on the Truelove-Witts criteria were considered to have active UC. In addition to RDW, serum C-reactive protein levels, erythrocyte sedimentation rates, and platelet counts were measured. Results: Twenty-nine (51.7%) patients with CD and 35 (57.4%)patients with UC had active disease. The RDW was significantly higher in patients with CD and UC than in controls (p<0.001 and p<0.001, respectively). A subgroup analysis indicated that for a RDW cut-off of 14%, the sensitivity for detecting active CD was 79%, and the specicity was 93% (area under curve [AUC], 0.935; p<0.001). RDW was the most sensitive and specifi c marker for active CD. However, it was not valid for UC, as the ESR at a cutoff of 15.5 mm/hr showed a sensitivity of 83% and a specicity of 76% (AUC, 0.817;p<0.001), whereas the RDW at a cutoff of 14% showed 17%sensitivity and 84% specicity for detecting active UC. Conclusions:RDW was elevated in IBD in comparison with healthy controls and increased markedly in active disease. RDW may be a sensitive and specifi c marker for determining active CD,whereas ESR is an important marker of active UC.
