Elimination of Dietary Triggers Is Successful in Treating Symptoms of Gastroesophageal Reflux Disease.

BACKGROUND: The relationship between aliments and pathophysiological abnormalities leading to gastroesophageal reflux disease (GERD) symptoms elicitation is unclear. Nevertheless, patients often report symptoms after ingestion of specific foods. AIMS: To identify in primary care setting the presence of foods able to trigger GERD symptoms, and evaluate whether a consequent specific food elimination diet may result in clinical improvement. METHODS: Diagnosis of GERD and quantification of reflux symptoms were done according to GERD-Q questionnaire (positive when > 8). During clinical data collection, patients were asked to report aliments associated with their symptoms. Also, a precompiled list of additional foods was administered to them. Then, patients were requested to eliminate the specific foods identified, and to come back for follow-up visit after 2 weeks when GERD-Q questionnaire and clinical data collection were repeated. RESULTS: One-hundred GERD (mean GERD-Q score 11.6) patients (54 females, mean age 48.7 years) were enrolled. Eighty-five patients reported at least one triggering food, mostly spicy foods (62%), chocolate (55%), pizza (55%), tomato (52%), and fried foods (52%). At follow-up visit, the diagnosis of GERD was confirmed in only 55 patients, and the mean GERD-Q score decreased to 8.9. Heartburn reporting decreased from 93 to 44% of patients, while regurgitation decreased from 72 to 28%. About half of the patients agreed to continue with only dietary recommendations. CONCLUSIONS: Most patients with GERD can identify at least one food triggering their symptoms. An approach based on abstention from identified food may be effective in the short term.

The Management of Patients With Diverticulosis and Diverticular Disease in Primary Care: An Online Survey Among Italian General Pratictioners.

GOALS: To investigate the current opinion of Italian general practitioners (GPs) on the management of patients with diverticular disease (DD) of the colon. BACKGROUND: The management of DD remains a point of debate, and guidelines are not uniform in their advice. STUDY: A web-based survey was conducted among Italian GPs. Twelve questions were aimed at the diagnosis, treatment, and management options for diverticulosis and symptomatic DD. RESULTS: In total, 245 surveys were filled out. A high-fiber diet was prescribed widely in diverticulosis (44%), together with advice to allow seeds (30%). Rifaximin (26%) and probiotics (25%) were the most frequently prescribed drugs in this population. Colonoscopy was the most prescribed instrumental tool in the diagnosis (77%) and follow-up (21%) of symptomatic uncomplicated diverticular disease patients. Rifaximin, probiotics, and mesalazine were the most frequently prescribed drugs in symptomatic uncomplicated diverticular disease patients (82.8, 59.5%, and 36.3%, respectively). Finally, 77% of the Italian GPs prescribed laboratory exams in the follow-up of these patients. The vast majority of the Italian GPs (83%) managed suspected acute diverticulitis at home, and did not consider two episodes of acute diverticulitis as a strict surgical indication (86%). Rifaximin, probiotics, and mesalazine were the most frequently prescribed drugs to prevent recurrence of the disease (42.5%, 28.2%, and 12.4%, respectively). Finally, 87% of the Italian GPs prescribed laboratory examinations in the follow-up of these patients. CONCLUSIONS: This survey shows that the current management of DD in primary care by Italian GPs is not fully in line with current guidelines and more recent literature data.

Association between coeliac disease and psoriasis: Italian primary care multicentre study.

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.

Efficacy of a Food Supplement Containing Lactobacillus acidophilus LA14, Peptides, and a Multivitamin Complex in Improving Gastroesophageal Reflux Disease-Related Outcomes and Quality of Life of Subjects Showing Mild-to-Moderate Gastroesophageal Reflux Disease.

Dietary interventions represent an interesting alternative to pharmacological treatments for improving the quality of life (QoL) of subjects suffering from gastroesophageal reflux disease (GERD). This randomized, double-blind, placebo-controlled study aimed to evaluate the efficacy of a food supplement (FS) containing a probiotic strain, bioactive peptides, and vitamins in relieving heartburn/dyspeptic symptoms in subjects with mild-to-moderate GERD. Fifty-six adult participants were randomly assigned to receive the placebo or the active FS for 28 days. Subjects were asked to record daily the frequency and intensity of heartburn episodes and the intake of over- the-counter (OTC) medications. GERD-QoL and self-assessment questionnaires were also completed every two weeks and at the end of the treatment, respectively. FS was effective in achieving a progressive and significant reduction of heartburn frequency and severity, with an intergroup significant difference at the end of the treatment period. FS group also reported a reduction in the OTC medication intake, whereas placebo administration did not modify the OTC intake. Results from the QoL and self-assessment questionnaires showed that FS administration achieved a progressive and statistically significant intragroup and intergroup improvement in the QoL score and a higher positive response with respect to the placebo treatment.

Assessment of small intestinal bacterial overgrowth and methane production in patients on chronic proton-pump inhibitor treatment: prevalence and role of rifaximin in its management in primary care.

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 (CH4) production consequent to chronic PPI therapy using Lactulose Breath Test (LBT). Secondary aim was to explore the possible role of rifaximin in treating PPI-induced SIBO patients. METHODS: One hundred twenty-five gastroesophageal reflux disease patients, constantly treated with PPI for at least 6 months and undergoing to LBT, were retrospectively assessed. An age-matched control population (control) of 100 patients, which had not used PPI in the last 6 months, was also enrolled. In the PPI group, SIBO positive patients and CH4 producers were treated with rifaximin 1200 mg/daily for 14 days and re-checked with LBT one month after the end of treatment. The area under the curve (AUC) before and after treatment was also calculated for both SIBO positive patients and CH4 producers. RESULTS: In the PPI group, SIBO prevalence was significantly higher vs. controls (38/125 [30.4%] vs. 27/100 [27%], P<0.05). 77/125 (61.6%) PPI patients were found to be CH4 producers vs. 21/100 (21%) controls (P<0.05). Among SIBO patients in the PPI group, 34 (89.4%) were also CH4 producers vs. 17/27 (63%) controls (P<0.05). After treatment, LBT resulted negative in 15/22 SIBO patients (68.1%) (P<0.05) and in 18/34 CH4 producers (52.9%) (P<0.05). At the AUC analysis, an overall reduction of 54.2% for H2 in SIBO patients and of 47.7% for CH4 was assessed after rifaximin treatment (P<0.05). CONCLUSIONS: Our data showed that chronic use of PPI could be able to increase the prevalence of SIBO and to shift the intestinal microbial composition towards a CH4-producing flora. rifaximin could represent a useful therapeutical option for PPI-induced SIBO and for modulating CH4-producing flora.

Translational Gap between Guidelines and Clinical Medicine: The Viewpoint of Italian General Practitioners in the Management of IBS.

Irritable bowel syndrome (IBS) guidelines are generally developed by experts, with the possibility of a translational gap in clinical medicine. The aim of our study was to assess an Italian group of general practitioners (GPs) for their awareness and use of criteria for the diagnosis and management of IBS. For this purpose, a survey was carried out involving 235 GPs, divided into two groups according to their years of activity: 65 "junior general practitioners" (JGPs) (≤10 years) and 170 "senior general practitioners" (SGPs) (>10 years). JGPs were more familiar with the Rome IV Criteria and Bristol Scale than SGPs. Abdominal pain, bowel movement frequency and bloating were the symptoms most frequently used to make a diagnosis. The most probable causes of IBS were reported to be abnormal gastrointestinal motility and psychological triggers. SGPs reported more frequently than JGPs that challenging management and patient's request were motivations for a gastroenterological consultation. The practice of clinical medicine is still far from the guidelines provided by the specialists. Abdominal pain related to defecation and changes in bowel frequency are considered to be the more important symptoms for IBS diagnosis, but most GPs, both JGPs and SGPs, like to consider abdominal bloating as another useful symptom. Involving both gastroenterologists and GPs in developing shared guidelines would be highly desirable in order to improve IBS management strategies in everyday clinical practice.

High prevalence of Cag-A positive H. pylori strains in ischemic stroke: a primary care multicenter study.

BACKGROUND: Previous studies suggested an association between CagA-positive H. pylori strains and ischemic stroke. The aim of the present study was to assess the prevalence of Helicobacter pylori infection and CagA status in patients with atherosclerotic stroke in the primary care setting. MATERIALS AND METHODS: A total of 106 consecutive patients (age 76.6 +/- 8 years; males 52%) with well-documented history of atherosclerotic stroke and 106 sex-age- (age 76.5 +/- 9 years; males 52%) and social background-matched controls without relevant vascular diseases. Risk factors for ischemic stroke were recorded in all subjects. H. pylori infection was assessed by[13]C-urea breath test. A serologic assay for specific IgG against CagA was performed in infected subjects. RESULTS: A trend toward a higher prevalence of H. pylori was observed in cases (63%) with respect to controls (54%) without reaching a statistical significance. CagA positivity was associated to a higher risk of atherosclerotic stroke (adjusted odds ratio 2.69, 95% confidence interval 1.37-5.30). CONCLUSIONS: Our findings suggest that CagA-positive strains of H. pylori are significantly associated to atherosclerotic stroke. This is not a merely confirmative study since it has been performed for the first time in the primary care setting and included only subjects with an active infection.

Appropriateness in prescribing PPIs: A position paper of the Italian Society of Gastroenterology (SIGE) - Study section "Digestive Diseases in Primary Care".

The introduction of proton pump inhibitors (PPIs) into clinical practice about thirty years ago has greatly improved our therapeutic approach to acid-related diseases for their well-recognized efficacy and safety. Despite the well-defined indications, however, the use of PPIs continues to grow every year in both western and eastern countries and this phenomenon poses serious queries that include the onset of potential adverse effects and the increase in health care costs. The major reason explaining this worrying market expansion is the inappropriate use of PPIs. In order to re-establish a correct use of these effective drugs in daily clinical practice, the Italian Society of Gastroenterology (SIGE), nominated a panel of experts who reviewed the available clinical literature and produced a series of updated position statements on the use of PPIs in clinical practice.

Nickel sensitization in patients with gastro-esophageal reflux disease.

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.

The management of patients with new onset of upper gastro-intestinal symptoms in primary care.

BACKGROUND: Data dealing with dyspepsia management in general practice are lacking, and most of the studies investigated a subset of patients with suspected peptic ulcer disease either with or without previous complaints. AIMS: To evaluate the one-year management of patients presenting new onset upper abdominal symptoms without alarming features. METHODS: 275 patients were enrolled by 63 Italian general practitioners. RESULTS: Referral to upper gastro-intestinal tract endoscopy resulted significantly higher in patients with predominant epigastric pain compared to subjects with non-painful symptoms or non-dominant symptoms. Amongst drug therapies, only prokinetics and antacids and anti-secretory therapies were prescribed differently amongst clinical subgroups. The rate and type of management and referrals resulted were not influenced by the age of patients or the use of anti-inflammatory drugs. The most frequent diagnosis at one-year follow-up was reflux oesophagitis. The absence of organic disease was less frequent in patients with dominant epigastric pain than non-painful or non-dominant symptoms. CONCLUSION: The management of these patients in primary care in Italy is mainly determined by clinical presentation, independent of age. Any judgement about appropriateness of the treatment should consider not only conventional features such as age, but the more complex individual frameworks as well.
