Coeliac disease (CD) is an autoimmune disorder of the small bowel associated with increased risk of additional autoimmune diseases (ADs).To investigate the prevalence of ADs in a population of adult coeliac patients.This was a retrospective case–control study. Data from coeliac patients and controls referred to a tertiary center between 2013 and 2016 were collected. The frequency of ADs and the unadjusted and adjusted odds ratios (ORs) for age, gender, disease duration, and body mass index with their 95% confidence intervals (CIs) were evaluated.Two hundred fifty-five patients with CD (median age 37.1 years; 206 women) were matched with 250 controls. ADs were more frequent (35.3%) in coeliac patients than in controls (15.2%). Adjusted ORs for the presence of only 1, at least 1, and more than 1 AD were 3.13 (95% CI 1.81–5.42, P < .0001), 3.31 (95% CI 2.00–5.46, P < .0001), and 3.93 (95% CI 1.49–10.36, P = .006), respectively. Hashimoto thyroiditis was the most prevalent AD (24.3% vs. 10%) OR = 2.55 (95% CI 1.39–4.70, P < .0001), followed by psoriasis (4.3% vs. 1.6%), type 1 diabetes (2.7% vs. 0.4%), and Sjögren syndrome (2.4% vs. 0.4%).These findings suggest a need for a careful surveillance of autoimmune status, especially for Hashimoto thyroiditis in patients with celiac disease.

Over the past 50 years, the prevalence of Helicobacter pylori infection has fallen as standards of living improved. The changes in the prevalence of infection and its manifestations (peptic ulcer disease and gastric mucosal lesions) were investigated in a large cohort of Sardinians undergoing upper endoscopy for dyspepsia. A retrospective observational study was conducted involving patients undergoing endoscopy for dyspepsia from 1995 to 2013. H. pylori status was assessed by histology plus the rapid urease test or 13C-UBT. Gastric mucosal lesions were evaluated histologically. Data including non-steroidal anti-inflammatory drugs (NSAIDs) use and the presence of peptic ulcers were collected. The prevalence of H. pylori was calculated for each quartile and for each birth cohort from 1910 to 2000. 11,202 records were retrieved for the analysis (62.9% women). The overall prevalence of H. pylori infection was 43.8% (M: 46.6% vs. F: 42.0%; P = 0.0001). A dramatic decrease in the prevalence of infection occurred over the 19-year observation period. The birth cohort effect was evident in each category (quartile) reflecting the continuous decline in H. pylori acquisition. Over time, the prevalence of peptic ulcers also declined, resulting in an increase in the proportion of H. pylori negative/NSAID positive and H. pylori negative/NSAID negative peptic ulcers. The prevalence of gastric mucosal changes also declined despite aging. The decline in H. pylori prevalence over time likely reflects the improvement in socioeconomic conditions in Sardinia such that H. pylori infection and its clinical outcomes including peptic ulcer are becoming less frequent even among dyspeptic patients.

Clinical studies have shown that bismuth-containing quadruple therapy given twice a day for 10 to 14 days is effective and safe in the treatment of Helicobacter pylori infection in Sardinia. However, bismuth is no longer available in Italy.To report the effectiveness and tolerability of pantoprazole 20 mg, tetracycline 500 mg, and metronidazole 500 mg given b.i.d. (with the midday and evening meals) for 10 days supplemented with Lactobacillus reuteri (DSM 17938) 108 cfu/tablet once a day for 20 days in patients treated in a routine daily practice setting.H pylori infection was defined as a positive gastric histopathology and/or 13C-Urea Breath Test (UBT) and/or stool antigen testing. Successful eradication was documented by 13C-UBT, and/or stool antigen assay at least 4 weeks post-therapy. Compliance and side effects were recorded after completing treatment.A total of 45 patients (10 men, 35 women; mean age 52.6 years) have completed the treatment regimen with the success rate of 93% (95% confidence interval = 85–99%). Compliance was excellent. Side effects were absent or generally mild.Proton pump inhibitor-tetracycline-metronidazole-L reuteri therapy provided high eradication rates with few side effects and therefore can safely replace bismuth in H pylori treatment. Further studies are needed that include susceptibility testing.

The aim of this study was to investigate the relationship between body mass index (BMI) categories and comorbidity in 9067 patients (age range 18‒94 years) who underwent upper digestive endoscopy in Northern Sardinia, Italy. The majority of participants (62.2%) had a BMI under 25 kg/m2, overweight was detected in 30.4%, and obesity (BMI ≥ 30 kg/m2) in 7.4% of patients. The most frequent illness recorded was hypertension followed by cardiovascular and liver disease. The multivariate analysis, after adjusting for sex, residence, marital status, smoking habits, occupation and hospitalization detected an association between comorbidity and aging that was statistically significant and progressive. Among patients younger than 60 years (n = 5612) the comorbidity risk was higher for BMI ranging 27.5‒29.9 kg/m2 compared with BMI 25.0‒27.4 kg/m2 (RR = 1.38; 95% CI 1.27‒1.50 vs. RR = 0.86; 95% CI 0.81‒0.90). In patients older than 60 years (n= 3455) the risk was lower for a BMI in the range 27.5–29.9 kg/m2 compared with a BMI in the range 25.0–27.4 kg/m2 (RR = 1.11; 95% CI 1.05‒1.18 vs. RR = 1.28; 95% CI 1.21‒1.35). These results suggest that being moderately overweight is a marker of a healthy aging process and might protect, at least in part, against comorbidity. However, further research is needed to better understand this unexpected finding.

In this endoscopic study, colonic diverticulosis in Northern Sardinia showed prevalence similar to other series in Western countries, and it was predominantly left sided and age related.

BackgroundSubjects with glucose-6-phosphate dehydrogenase (G6PD) deficiency may be more susceptible to infections due to impaired leukocyte bactericidal activity. The disorder is common in the Mediterranean area. The aim of this study was to investigate whether G6PD deficiency may be a risk factor for acquiring H. pylori infection.MethodsWe performed a retrospective study. Data from clinical records of 6565 patients (2278 men and 4287 women, median age 51, range 7‒94) who underwent upper endoscopy between 2002 and 2014 were collected. H. pylori status, assessed by histology plus rapid urease test or 13C-urea breath test, and G6PD status were also reported. A multiple logistic regression model was used to investigate the association between G6PD deficiency and H. pylori infection.ResultsEnzyme deficiency was detected in 12% (789/6565) of the entire cohort, and more specifically in 8.3% of men and in 14.0% of women. Overall, the proportion of patients positive for H. pylori was 50.6% and 51.5% among G6PD deficient and non-deficient patients (χ² = 0.271; p = 0.315). Moreover, among G6PD-deficient and normal patients the frequency of previous H. pylori infection was similar. After adjustment for age and gender the risk for acquiring H. pylori infection was similar in G6PD-deficient and normal patients. Only age was a strong statistically significant risk predictor.ConclusionsThese results demonstrate for the first time that G6PD deficiency does not enhance patients’ susceptibility to acquire H. pylori infection in Sardinia.
