研究概览
简要总结
This study aims to assess whether it is feasible to use a point of care test to increase the detection of coeliac disease in a pharmacy setting.
详细描述
Coeliac disease (CD) is an autoimmune condition characterised by mucosal damage of the small intestine by dietary gluten. CD affects 1 in 100 people. However, patients do not always have symptoms, resulting in 5 undiagnosed patients to every known case of CD. Undiagnosed CD can lead to complications such as vitamin and mineral deficiencies, osteoporosis and small bowel lymphoma, as well as impairing quality of life.
Currently, patients are diagnosed with a conventional blood test for coeliac antibodies (anti-TTG) as a first line test. Simtomax®, a new coeliac point of care test (POCT), has become available. It is a finger prick test that provides results of a coeliac antibody, deaminated gliadin peptide, within 10 minutes. Studies showed that Simtomax is as accurate as anti-TTG, with a 92.7% chance of detecting CD and 98.7% chance of ruling out CD.
This study aims to assess whether the POCT can increase the detection of adult coeliac disease when used in a pharmacy setting. A feasibility study using a case-finding approach will be conducted at 5 pharmacies in Sheffield over 20 months. It will be funded by Professor Sanders' research funds.
Customers who enter the pharmacies will be approached by the principal investigator (PI). Eligible participants (those with symptoms suggestive of or risk factors for CD) will be consented for the POCT by the PI. The POCT will be carried out at the pharmacies. Any participant with a positive test will be advised to see his GP to be referred for a gastroscopy at the Royal Hallamshire Hospital to confirm the diagnosis. Once diagnosed, the participant will follow the standard management pathway for any patients with CD.
Results of the study will be compared to the established prevalence of CD of 1%, to assess whether using POCT in a pharmacy setting can increase the detection of adult CD.
