Clinical Trial: Role of the Microbiome in Graves' Orbitopathy

Study Status: Completed
Recruit Status: Unknown status
Study Type: Interventional

Official Title: Investigation of Novel Biomarkers and Definition of the Role of the Microbiome In Graves' Orbitopathy

Brief Summary: Graves' orbitopathy (GO), also known as thyroid eye disease, affects approximately 3 million people in Europe with an estimated socioeconomic burden of 6.4 billion euros per annum. GO is a complication of Graves' disease which is an autoimmune disease and the commonest cause of an overactive thyroid gland. The treatment of GO remains unsatisfactory and the majority of patients report long-term impairment of quality of life. The effects of gut derived antigens, from micro-organisms and nutrients, on the autoimmune response will be tested in the animal model by probiotic and "contra-biotic" intervention. In the Indigo interventional trial the investigators will add to the standard anti-thyroid drug treatment (ATD) a specifically designed probiotics (LAB4, Cultech Ltd., West Glamorgan, UK) to assess whether it is possible to modify the microbiome in GD patients and improve their immunological status.

Investigation of Novel biomakers and Definition of the role of the microbiome In Graves' Orbitopathy (GO) (INDIGO)

Background Graves' orbitopathy (GO), also known as thyroid eye disease, affects approximately 3 million people in Europe with an estimated socioeconomic burden of 6.4 billion euros per annum. GO is a complication of Graves' disease which is an autoimmune disease and the commonest cause of an overactive thyroid gland. The treatment of GO remains unsatisfactory and the majority of patients report long-term impairment of quality of life. To improve the outcomes of people with GO and thus reduce long-term illness and cost to society, research is needed to address the identification of risk factors, develop a better understanding of the pathophysiology of the disease, devise approaches for early diagnosis during the pre-clinical stage of the disease, and create novel and safe interventions. The effects of gut derived antigens, from micro-organisms and nutrients, on the autoimmune response will be tested in the animal model by probiotic and "contra-biotic" intervention. In the Indigo interventional trial the investigators will add to the standard anti-thyroid drug treatment (ATD) a specifically designed probiotics (LAB4, Cultech Ltd., West Glamorgan, UK) to assess whether it is possible to modify the microbiome in GD patients and improve their immunological status.

Primary objective:

To modify the microbiome in GD patients to reduce pathogenic species and enrich its commensal, symbiotic components.

Secondary objective:

To decrease the anti-TSHr antibody titer and the concentration of IgG and IgA in GD patients.

modification the microbiome in GD patients to reduce pathogenic species and enrich its commensal, symbiotic components. The proportion (%) of each species will be assessed and recorded.



Original Primary Outcome: Same as current

Current Secondary Outcome: Improvement immunological status (antibody responses will be analyzed to identify if microbial or food derived antigens are involved in triggering disease or associated with GO progression) [ Time Frame: 6 months ]

To decrease the anti-TSHr antibody titer and the concentration of IgG and IgA in patients with Graves' disease. The concentration of each parameter will be assessed in mg/dl and recorded.


Original Secondary Outcome: Same as current
