<b><i>Background and Aim:</i></b> Many investigations have demonstrated that changes in body weight are frequent in patients with coeliac disease (CD) after a gluten-free diet (GFD); conversely data on the metabolic syndrome (MS) and hepatic steatosis (HS) are still rare. The aim is to evaluate the prevalence of MS and HS in patients with CD, before and after a GFD. <b><i>Methods:</i></b> One hundred eighty-five coeliac adult patients were enrolled in the study. Diagnosis of MS was made according to the current international criteria including waist circumference (WC), hypertension, reduction of high-density lipoprotein (HDL) cholesterol, hypertriglyceridemia, and hyperglycemia. Body mass index (BMI), hypercholesterolemia, and HS were also assessed. <b><i>Results:</i></b> CD patients showed an increased risk of developing both MS and HS after following a GFD. MS was reported in 3.24% of the cases at the time of CD diagnosis and in 14.59% after GFD (<i>p</i> &#x3c; 0.0001). HS was reported in 1.7% at the time of diagnosis and in 11.1% after GFD (<i>p</i> &#x3c; 0.0001). With regard to metabolic sub-categories, the prevalence of the increase in WC, hypertension, reduction of HDL cholesterol, hyperglycemia, hypercholesterolemia, and BMI &#x3e; 25 was significantly higher after GFD compared to baseline at CD diagnosis. <b><i>Conclusion:</i></b> In CD patients, following a GFD maybe can contribute to the development of MS and HS. Patients should be informed about this possible risk.

Background: Celiac disease (CD) often manifests with dyspeptic symptoms and chronic gastritis is a common finding. Aim: To evaluate the frequency of lymphocytic gastritis (LG), chronic active gastritis (CAG), and chronic inactive gastritis (CIG) in patients with CD, before and after gluten-free diet (GFD). Methods: A five-year prospective study including all consecutive patients with a new diagnosis of CD was conducted. Gastric and duodenal biopsy specimens taken both at the time of the CD diagnosis and at the first endoscopic control after 18-24 months on GFD were evaluated. Results: 213 patients with CD were enrolled. At the time of the diagnosis, 42 patients (19.7%) showed normal gastric mucosa, 34 (15.9%) LG, 67 (31.5%) CAG, and 70 (32.9%) CIG. Out of the 34 patients with LG, all were Helicobacter pylori negative and the majority of them showed an improvement both of gastritis (94.1%) and duodenal lesions (82.3%) after GFD. GFD did not show significant effects on CAG and CIG. Conclusions:LG is present in 16% of CD patients, it is not associated with H. pylori infection, and it improves after GFD. Both CAG and CIG are also frequently associated with CD, but fail to respond to a GFD.

Background and Objectives: Conflicting evidence is reported regarding any association between colonic diverticula with colorectal adenomas or cancer. The present study aimed to evaluate, in a cohort of Caucasian patients, the association between colonic diverticula and colorectal polyps and cancer. Materials and Methods: All consecutive patients undergoing colonoscopy at our institution were included in the study. The presence and location of diverticula, polyps, and cancers were recorded. Histologically, polyps were classified as adenoma (with low or high dysplasia), hyperplastic, or inflammatory. The relative risk of the association of polyps and cancer with diverticula was assessed. Multiple logistic regression analyses, including age, sex, family history for colorectal cancer (CRC), and family history for diverticula, were carried out. Results: During the study period, 1490 patients were enrolled; 37.2% (n = 555) showed colonic diverticula or polyps or CRC (308 males, mean age 66 years). Particularly, 12.3% (n = 183) patients presented only diverticula, 13.7% (n = 204) only polyps or cancer, 11.3% (n = 168) both diseases, and 62.7% (n = 935) neither diverticula nor polyps and cancer. A total of 38 patients presented colorectal cancer, 17 of which had also diverticula. A significant increase in relative risk (RR 2.81, 95% CI 2.27–3.47, p < 0.0001) of colorectal adenoma and cancer in patients with colonic diverticula was found. At multivariate analysis, only diverticula resulted to be significantly associated with colorectal adenomas and cancer (Odds Ratio, OR 3.86, 95% CI 2.90–5.14, p < 0.0001). Conclusions: A significant association of colonic diverticula with colorectal adenoma or cancer was found. This implies that patients with colonic diverticula require a vigilant follow-up procedure for the prevention of colorectal cancer from those applicable to the general population.
