Yields of dual therapy containing high-dose proton pump inhibitor in eradication of H. pylori positive dyspeptic patients.

UNLABELLED: BACKGROUND/AIMs: H. pylori eradication has been recommended for dyspeptic patients in high prevalance regions. Triple therapies are still prescribed mostly because culture and antibiotic susceptibility tests aren't widely available in the world. Dual therapy with high-dose proton pump inhibitors reported to have higher eradication rates. Our objective was to determine eradication success and cost-effectivity of dual therapy in dyspeptic patients. METHODOLOGY: Patients were treated orally with either dual (n:74,omeprazole 20mg q.i.d and amoxicillin 1g b.i.d) or triple therapy (n:116,omeprazole 20mg b.i.d and amoxicillin 1g b.i.d and clarithromycin 500mg b.i.d) for 14 days. HpSA was requested 3 months later. The results were evaluated statistically, p values ˂0,05 were considered significant. RESULTS: Patients (n:190) were included the study((80 female,110 male, mean age: 35.6±11year(p<0.001)). Alcohol/smoking, endoscopic findings and H. pylori rates with pathological examinations were not significantly different between groups whereas there was a significant difference in HpFast tests(p<0.01). When examined with HpSA tests 3 months after the treatment, eradication rate was 81.1% in the dual therapy group versus 63.8% in the triple therapy group (p:0.011). Dual therapy was economic than triple therapy (144USDvs.107USD,p<0.001). CONCLUSIONS: Dual therapy seems more successful, cost-effective and is less risky in terms of side effects compared to standard triple therapy in patients with dyspepsia.

Functional disability in Alzheimer disease: a validation study of the Turkish version of the disability assessment for dementia scale.

This study aimed to determine the reliability and validity of the Turkish version of Disability Assessment for Dementia (DAD) scale in the Turkish elderly population with Alzheimer disease (AD). The DAD scale was administered to the primary caregivers of 157 patients (age 77.7 ± 6.8 years) with AD. The Turkish version of the DAD scale showed high internal consistency (Cronbach α = .942), excellent test-retest, and interrater reliability (intraclass correlation coefficient [ICC] = 0.996 and ICC = 0.994, respectively). The DAD scale was significantly correlated with activities of daily living (ADL; Modified Older Americans Research Survey ADL) and instrumental activities of daily living (IADL; Lawton and Brody IADL) scales (r = .89, P < .001 and r = .90, P < .001). Disability Assessment for Dementia had a high negative correlation with the Global Deterioration Scale (GDS; r = -.880, P < .001). Post hoc comparisons with Tukey test showed significant differences in the mean DAD scores in different GDS stages. Construct validity was estimated using total score correlation analyses between the standardized Mini-Mental State Examination (MMSE) and the DAD scale. Results revealed high and significant correlation between MMSE score and DAD scale (r = .812, P < .001). The results of multivariate analysis showed that DAD score was not correlated with gender, education, and age. The DAD total score was affected mostly by GDS, MMSE, and duration of the disease. Turkish version of the DAD scale was found to be a reliable and valid instrument to assess functional disability in Turkish elderly patients with AD. This scale assists caregivers and physicians to decide for proper interventions.
