This study analyzes the effect of short- and long-term omeprazole (OM) on duodenal ulcer healing, recurrence, and H. pylori status.
Patients affected by active duodenal ulcer were randomly allocated ...to treatment with OM 20 mg or 40 mg once daily for 4 wk. Subsequently, patients with healed duodenal ulcer were randomly assigned to one of the following three groups: OM 20 mg once daily for 12 months, OM 20 mg alternate days for 12 months, and no treatment. Endoscopy was performed at entry, at 4 wk, and after 4, 8, and 12 months. Two biopsy specimens from antrum, body, and fundus were taken for histology and search for H. pylori. One hundred and eighty patients with active duodenal ulcer were admitted. Ninety-one were treated with OM 20 mg once daily and 89 with OM 40 mg for 4 wk.
The results at 4 wk show 92.8% patients healed with OM 20 mg and 95.1% at 40 mg (NS). In the second part of the study, 96 of the patients who healed at 4 wk (45 with OM 20 mg, and 51 with OM 40 mg) entered the long-term study. Thirty-six patients received OM 20 mg daily for 12 months, 35 OM 20 mg on alternate days for 12 months, and 25 patients no treatment. The results show a healing rate of 100%, 100%, and 95% with OM 20 mg daily, of 97%, 95%, and 93% with OM 20 mg on alternate days, and of 81%, 50%, and 40% (p < 0.01) with no treatment at 4, 8, and 12 months, respectively. H. pylori that was found in 97% of patients at entry, at 4 wk was found in 92.8% of patients treated with OM 20 mg and in 97.5% of patients treated with OM 40 mg (NS). In one-third of the patients, H. pylori disappeared from the antrum but was found in the fundus. A 30% reduction in the presence of H. pylori was seen in the group treated with 20 mg daily for 12 months.
We conclude that both continuous and alternate-day long-term OM treatment at 20 mg are similarly efficacious in the prevention of duodenal ulcer recurrence. Healing active duodenal ulcers with 20 or 40 mg does not influence subsequent treatment. Long-term OM at 20 mg daily for 12 months suppresses H. pylori temporarily in one-third of the patients. In these patients however, H. pylori reactivates after the end of treatment.
Non-celiac gluten sensitivity (NCGS) is still an undefined syndrome with several unsettled issues despite the increasing awareness of its existence. We carried out a prospective survey on NCGS in ...Italian centers for the diagnosis of gluten-related disorders, with the aim of defining the clinical picture of this new syndrome and to establish roughly its prevalence compared with celiac disease.
From November 2012 to October 2013, 38 Italian centers (27 adult gastroenterology, 5 internal medicine, 4 pediatrics, and 2 allergy) participated in this prospective survey. A questionnaire was used in order to allow uniform and accurate collection of clinical, biochemical, and instrumental data.
In total, 486 patients with suspected NCGS were identified in this 1-year period. The female/male ratio was 5.4 to 1, and the mean age was 38 years (range 3-81). The clinical picture was characterized by combined gastrointestinal (abdominal pain, bloating, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and systemic manifestations (tiredness, headache, fibromyalgia-like joint/muscle pain, leg or arm numbness, 'foggy mind,' dermatitis or skin rash, depression, anxiety, and anemia). In the large majority of patients, the time lapse between gluten ingestion and the appearance of symptoms varied from a few hours to 1 day. The most frequent associated disorders were irritable bowel syndrome (47%), food intolerance (35%) and IgE-mediated allergy (22%). An associated autoimmune disease was detected in 14% of cases. Regarding family history, 18% of our patients had a relative with celiac disease, but no correlation was found between NCGS and positivity for HLA-DQ2/-DQ8. IgG anti-gliadin antibodies were detected in 25% of the patients tested. Only a proportion of patients underwent duodenal biopsy; for those that did, the biopsies showed normal intestinal mucosa (69%) or mild increase in intraepithelial lymphocytes (31%). The ratio between suspected NCGS and new CD diagnoses, assessed in 28 of the participating centers, was 1.15 to 1.
This prospective survey shows that NCGS has a strong correlation with female gender and adult age. Based on our results, the prevalence of NCGS seems to be only slightly higher than that of celiac disease.
