RESUMO
BACKGROUND: Although proton pump inhibitor (PPI) drugs have considered able to induce small intestinal bacterial overgrowth (SIBO), no data are so far available from primary care (PC). We assessed the prevalence of SIBO and methane (CH

BACKGROUND: Rising antibiotic resistance requires the evaluation of new and effective therapies. AIMS: To test the efficacy and safety of the new bismuth-containing quadruple therapy in patients infected with Helicobacter pylori. MATERIAL AND METHODS: Consecutive H. pylori-positive dyspeptic patients were enrolled, either naïve or with previous failure treatment. Patients were treated with Pylera® (three-in-one capsules containing bismuth subcitrate potassium 140 mg, metronidazole 125 mg, and tetracycline 125 mg) three capsules q.i.d. plus omeprazole 20 mg or esomeprazole 40 mg b.i.d. for 10 days. Eradication was confirmed using an urea breath test (at least 30 days after the end of treatment). Efficacy was assessed by UBT and safety by means of treatment-emergent adverse events. RESULTS: One hundred and thirty-one patients were included in the study: 42% of patients were naïve, and 58%, with previous failure treatment. H. pylori eradication was achieved in 124 patients (94.7%, 95% confidence intervals (CIs) 89.3-97.8) in ITT population. In the PP population, the percentage was 97.6% (95%, CIs 93.3-99.2). No difference in eradication rate was found either between naïve and previously treated patients (92.7% vs 96.0%, P=.383), or smoking and nonsmoking ones, or in patients taking omeprazole or esomeprazole. Treatment-emergent adverse events occurred in 35 patients (26.7%, 95% CIs 19.9-34.9). They were mild in all cases except in four, who discontinued the study due to diarrhea (three patients) and diffuse urticarial rush (one patient). CONCLUSIONS: Pylera® achieved a remarkable eradication rate in clinical practice, irrespective if it was used as first treatment or as a rescue therapy. Treatment-emergent adverse events were uncommon generally mild.

BACKGROUND: Gastro-esophageal reflux disease (GERD) leads to frequent medical visits, and available therapies fail in up to 40% of patients. Food allergies may be involved in GERD pathogenesis; however, allergens other than food have received little attention. Nickel allergy is common in the general population and some high-nickel foods are associated with GERD. However, the potential relationship between nickel allergy and GERD remains unaddressed. AIM: This study aimed to evaluate the prevalence of nickel sensitization in patients with and without GERD and to compare clinical and demographic features. METHODS: This prospective, multicenter study included 210 adult GERD patients and 140 patients without GERD who presented at the general practitioner. All GERD patients had undergone treatment with proton pump inhibitors and upper digestive endoscopy within the previous five years. Demographic and clinical data were collected by questionnaire and patients underwent a nickel patch allergy test. RESULTS: Patients with and without GERD presented similar characteristics, with the exception of nickel sensitization, which was significantly more prevalent among GERD patients than controls (39.5% vs. 16.4%; p = 0.001). Nickel-positive GERD patients were more frequently female (90.4% vs. 65.4%, p = 0.003) and asthmatic (18.1% vs. 4.7%; p = 0.038), compared to nickel-negative GERD patients. At six-month follow-up, most of the patients, with or without nickel sensitization, reported improved symptoms without differences in drug prescription. CONCLUSION: Nickel sensitization is particularly prevalent in GERD patients seen in general practice. Whether allergies other than food allergy play a role in GERD remains to be elucidated.
RESUMO
BACKGROUND: Studies assessing the association between coeliac disease (CD) and psoriasis show conflicting results. OBJECTIVE: To assess in the primary care setting the prevalence of CD in patients with psoriasis and the response to a gluten-free diet (GFD) in subjects with psoriasis and CD. METHODS: We enrolled 218 patients with psoriasis and 264 controls. Coeliac screening was carried out in all subjects (Eurospital, Trieste, Italy). In subjects with a positive serology, the diagnosis of CD was confirmed histologically. RESULTS: Nine (4.1%) psoriatic patients had positive anti-tissue transglutaminase antibodies compared to only 1 among controls (0.4%, p < 0.05; OR 2.03, 95% CI 1.42-90.11). The diagnosis of CD was confirmed histologically in all 10 subjects. At 6 months GFD was associated with a great improvement of skin lesions in 7 out of 8 patients with psoriasis. CONCLUSION: Our multicentre primary care study showed an high prevalence of CD in psoriasis and an improvement of skin lesions in CD under GFD.
