In 32 patients with dermatitis herpetiformis (DH) we studied the effect of gluten-free (22 patients) and gluten-reduced (10 patients) diet for periods ranging between 15 and 43 months. Variables such as cutaneous manifestations, dependence on dapsone, IgA deposits in the skin, small-bowel function, and jejunal mucosal morphology were studied. 59% of the patients on gluten-free diet could stop dapsone medication and remain symptom-free, compared with 10% on gluten-reduced diet. The time needed to achieve this therapeutic response varied from 5 to 31 months. IgA decreased in the skin to a degree which roughly paralleled the morphological normalization of the jejunal mucosa. In no patient, however, did the IgA completely disappear. It is suggested that IgA is not the main factor inducing DH symptoms, but rather a secondary phenomenon. Repeated jejunal biopsies revealed normalization of the mucosal histology in 52% of the patients on gluten-free diet, compared with none in the gluten-reduced diet group.

Coeliac disease is an autoimmune disease characterized by small intestinal villus atrophy and inflammation upon exposure to gluten. It has a global prevalence of approximately 1%. Although the gluten-free diet can be an effective treatment, this diet is burdensome with practical difficulties and frequent inadvertent gluten exposure.

Introduction: A gluten-free (GF) diet, the only treatment for people living with coeliac disease (CD), is challenging, and international guidelines highlight the valuable role of healthcare professionals in enabling self-management. The study aimed to explore the acceptability of telephone and online video consultations for adults with CD.
Methods: A cross-sectional study consisting of an online and paper survey was promoted to adults with CD.

Context: The efficacy of probiotics and diet management in irritable bowel syndrome (IBS) is controversial, and their relative effectiveness remains unclear.
Objective: This study aimed to evaluate the effects of probiotics, diet management, and their combination on IBS.
Data Sources: PubMed, Embase, Cochrane, and Web of Science were searched from inception to July 10, 2023, for relevant studies, including symptom relief, IBS-symptom severity score (-SSS), and IBS-quality of life measure (-QOL).

Purpose Of Review: Celiac disease (CeD) is a chronic autoimmune disorder of the small intestine triggered by gluten ingestion in genetically predisposed individuals. The cornerstone of CeD management remains a strict adherence to a lifelong gluten-free diet (GFD), although such a dietary restriction can lead to an altered quality of life and may not be easy to follow for many patients. These challenges highlighted the need for alternative therapies.

Background: The Mediterranean diet (MedD) exerts anti-inflammatory and anti-oxidant effects that are beneficial in autoimmune thyroid diseases (ATD). Recently, a gluten-free diet (GFD) has been proposed for non-celiac patients with Hashimoto's thyroiditis (HT), but its usefulness is under debate. The present pilot study evaluates the effects of these two dietary regimes, with a focus on redox homeostasis, in HT.
