Nutrient intakes during diets including unkilned and large amounts of oats in celiac disease.

BACKGROUND/OBJECTIVES: We have shown earlier that consumption of moderate amount of oats improve intakes of vitamin B(1), fiber, magnesium and iron in celiac patients using gluten-free diet (GFD). The objective of this study was to clarify the effect of high amount of both kilned and unkilned oats on food and nutrient intakes in celiac patients in remission. Kilning as an industrial heating process is performed to preserve the main properties of oats and to lengthen its useableness. Kilning may, however, change the protein structure of oats and therefore influence on the intake of nutrients. SUBJECTS/METHODS: The study group consisted of 13 men and 18 women with celiac disease in remission. The patients who were earlier using moderate amount of oats as part of their GFD were randomized to consume kilned or unkilned oats. After 6 months, the patients changed the treatment groups. The goal of daily intake of oats was 100 g. Food records and frequency questionnaire were used to follow nutrient intakes. RESULTS: Type of oats did not affect the amount of oats used. In the group using kilned oats, the intake of vitamin B1 and magnesium and in the group of unkilned oats that of magnesium and zinc increased significantly during the first 6 months (P

First-line eradication therapy for Helicobacter pylori in primary health care based on antibiotic resistance: results of three eradication regimens.

AIM: To determine the efficacy of three Helicobacter pylori eradication regimens and factors affecting the eradication results in Finland. METHODS: A total of 342 H. pylori-positive adult patients from primary health care referred for gastroscopy at 23 centres in different parts of Finland were randomized to receive either (i) lansoprazole 30 mg b.d., amoxicillin 1 g b.d. and metronidazole 400 mg t.d.s. (LAM), (ii) lansoprazole 30 mg b.d., amoxicillin 1 g b.d. and clarithromycin 500 mg b.d. (LAC), or (iii) ranitidine bismuth citrate 400 mg b.d., metronidazole 400 mg t.d.s. and tetracycline 500 mg q.d.s. (RMT). A (13)C-urea breath test was performed 4 weeks after therapy. RESULTS: The eradication result could be assessed in 329 cases. Intention-to-treat cure rates of LAM, LAC, and RMT were 78, 91 and 81%. The difference was significant between LAM and LAC (P = 0.01) and between LAC and RMT (P = 0.04). The eradication rates in cases with metronidazole-susceptible vs. -resistant isolates were for LAM 93% vs. 53% (P = 0.00001), for LAC 95% vs. 84%, and for RMT 91% vs. 67% (P = 0.002). Previous antibiotic use, smoking, and coffee drinking reduced the efficacy of therapy. CONCLUSIONS: In unselected patients in primary health care, LAC was the most effective first-line eradication.

Diagnostic methods in dyspepsia: the usefulness of upper abdominal ultrasound and gastroscopy.

OBJECTIVES: To examine the diagnostic value of gastroscopy and upper abdominal ultrasound, which are frequently used as primary tests in dyspeptic patients in general practice. To test the influence of age for accuracy of both diagnostic methods. DESIGN: Clinical study. SETTING: Four health centres in Kuopio Province, Finland. SUBJECTS: Four hundred unselected consecutive dyspeptic patients (91 less than 45 years of age) who consulted their general practitioners. MAIN OUTCOME MEASURES: Sensitivity, specificity, positive and negative predictive values (PV), efficiency and usefulness index (UI) were calculated for upper abdominal ultrasound and for gastroscopy in detecting the causes of dyspepsia in primary care. Final diagnosis was determined after one year follow-up. RESULTS: The sensitivity of upper abdominal ultrasound in detecting the cause of dyspepsia was 0.07, the specificity 0.91, PV+ 0.36, PV- 0.56, and UI -0.001. Ultrasound was not more efficient in older patients. Gastroscopy was the most efficient method with a sensitivity of 0.75, specificity 1.00, PV+ 0.99, PV- 0.83 and UI 0.56. The usefulness of gastroscopy was even better among patients over 45 years of age. CONCLUSIONS: The usefulness of upper abdominal ultrasound is low regardless of patient's age. Gastroscopy is superior to upper abdominal ultrasound as a first line diagnostic method in diagnosing dyspepsia, especially among patients over 45 years of age.
