Zinc Deficiency Treatment in Celiac Disease: Supplementation Versus Diet

Celiac DiseaseNutrient Deficiency

Micronutrient deficiencies are common amongst celiac disease (CeD) patients due to consumption of a restrictive and nutritionally unbalanced gluten-free diet (GFD) in addition to slow intestinal villi healing. Preliminary data of 221 patients attending our Celiac Disease Clinic at McMaster University show that 64% of patients on a GFD have nutrient deficiencies with zinc (Zn) deficiency affecting 48% of treated CeD patients. Dietary supplements are prescribed to treat Zn deficiency and it is unclear whether Zn levels can be restored with optimizing Zn in diet. This project will evaluate the the feasibility of dietary therapy to treat Zn deficiency in CeD in comparison to supplementation. Additional objectives of this pilot study, are to assess the efficacy of Zn optimized GFD compared to Zn supplements in 1) normalizing plasma Zn levels and 2) improving CeD gastrointestinal and extra-intestinal symptoms at 3 and 6 month. Subjects will be recruited from McMaster Celiac clinic. This randomized controlled trial aims to recruit 50 CeD participants with two treatment groups; zinc optimized diet (guided by dietitian to achieve target of 11 mg/day for females and 14 mg /day for males) or zinc oral supplementation (25 mg zinc gluconate tablet/day; 7 mg elemental Zn) with a total study a total study period of 6 months and 4 visits. To be included in the study the investigators require celiac diagnosed patients confirmed through CeD serology and duodenal biopsies adhering to a GFD > 6 months and plasma Zn ≤9.3 µmol/L. Questionnaires will be used to assess presentation of symptoms, dietary adherence, quality of life, depression and anxiety. The trial would be considered to be feasible if the enrolment fraction (i.e., number of enrolled patients /number of eligible patients) is 60% or above.

Tryptophan for Impaired AhR Signaling in Celiac Disease

Tryptophan Metabolism AlterationsCeliac Disease

This is a prospective, randomized, double-blind, placebo-controlled exploratory trial to evaluate the effect of L-tryptophan supplementation on celiac-related symptoms in individuals who have biopsy-confirmed celiac disease (CeD) and symptoms non-responsive to a gluten-free diet (GFD). Fifty participants, aged 18 to 75 years, who self-report persistent CeD-related symptoms despite taking a GFD for more than 1 year and who score > 40 on the Celiac Symptom Index (CSI) will be randomized to receive L-tryptophan or placebo for 3 weeks.

Probiotic Blend for Celiac Disease

Celiac Disease

The objective of the study is to develop a probiotic product (B. longum CCT 1934; B. lactis CCT 7858; L. rhamnosus CCT 7863; S. thermophilus ATCC 19258) to reduce the symptoms caused by celiac disease and concomitantly improve the quality of life of patients. To achieve the objective, 118 volunteers of both sexes will be included, randomly distributed into two groups: Test group (n=59): Volunteers supplemented with the probiotic product (Bifidobacterium longum CCT 1934; Bifidobacterium lactis CCT 7858; Lactobacillus rhamnosus CCT 7863 ; Streptococcus thermophilus ATCC 19258) Final concentration: 1 x 1010 CFU/ day) and Placebo group (n=59): Volunteers supplemented with placebo. The study will be conducted with patients diagnosed with celiac disease, the audience is adults (18 - 65 years old). The study will last for 90 days and volunteers will be invited to participate in three visits. During these visits, participants will be invited to answer the proposed questionnaires. The volunteer is expected to show improvement in gastrointestinal symptoms, as well as an improvement in quality of life after using the probiotic blend for 90 days.

A Study to Assess the Safety of TPM502 in Adults With Celiac Disease

Celiac Disease

The goal of this clinical trial is to learn about the safety and the pharmacodynamic (PD) effects of TPM502 in adults with celiac disease. The main questions it aims to answer are: if TPM502 is safe and well tolerated if TPM502 can induce modifications in parameters indicating that it may induce tolerance to gluten Participants will: undergo 1-day gluten challenge during screening and after administration of TPM502 or placebo. receive 2 infusions of TPM502 or placebo, 2 weeks apart

Safety and Efficacy of Fecal Microbiota Transplantation

Crohn DiseaseUlcerative Colitis25 more

The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.

Impact of a Low-FODMAP Gluten-free Diet on Gut Microbiota and Circulating miRNAs in Celiac Disease...

Celiac Disease

15 patients with refractory celiac disease (RCD) and 15 patients with CD responsive to the GFD between the ages of 21 and 60 will be enrolled. The aim of the research will be: 1) to characterize the intestinal, blood and duodenal microbiota, then to evaluate both the taxonomy of the identified bacteria and their relative abundance 2) to analyse the profile of miRNAs from biopsy and fibroblasts isolated in the first duodenal portion, highlighting any basal deregulation and, for fibroblasts, after treatment with the 33-mer immunogenic peptide 3) quantify and know the composition of the fecal microbiota in celiac patients with persistent symptoms and in refractory celiac patients before (T0) and after (T28) treatment with a low-FODMAP diet. The aim of the study is to observe a diversification of the microbiota pattern of refractory patients vs. normoresponsive celiac patients and to observe a deregulation in the expression of miRNAs, both basally on biopsies and after treatment with the immunogenic peptide in primary fibroblast cultures.
