    Celiac.com 02/26/2020 - Patients with established celiac disease can present with signs and symptoms requiring small bowel capsule endoscopy (SBCE) to assess for persistent disease beyond the duodenum and to rule out complications. 

    There is limited data celiac disease and histology, clinical and serological parameters as they reflect the extent of celiac disease on small bowel capsule endoscopy.

    A team of researchers recently set out to assess the role of small bowel capsule endoscopy in established celiac disease, by looking at the relationship between symptoms, celiac disease serology and Marsh classification of disease and extent of disease on small bowel capsule endoscopy in patients with established celiac disease.

    The team included S. Chetcuti Zammit; M. Kurien; D.S. Sanders; and R. Sidhu. They are associated with the Academic Department of Gastroenterology, Royal Hallamshire Hospital, Sheffield Teaching Hospitals in Sheffield, UK.

    The researchers conducted small bowel capsule endoscopies on 100 known celiac patients, and 200 control subjects. The results were reviewed by a team of experts.  The team noted the progression of disease on small bowel capsule endoscopy, celiac disease findings and small bowel transit times. The gold standard for diagnosing celiac disease is a duodenal histology, with D2 and Marsh 3a or above. The team's results show that small bowel capsule endoscopy can spot active disease with over 87% sensitivity, and 89% specificity. 

    Univariate analysis showed that the degree of affected small bowel mucosa correlates with the patient's age at small bowel capsule endoscopy, albumin, and hemoglobin, Marsh score of histology from the duodenal bulb (D1) and the second part of the duodenum, and refractory celiac disease on histology. 

    Multiple regression analysis, albumin and Marsh score of histology (D1) all showed vitamin B12 and folate levels to be measurably significant.  Celiac patients with complications including those with refractory celiac disease show much more affected SB mucosa.

    This is the first time a study has shown a connection between degree of disease and levels of malabsorption for duodenal histology markers, such as folate levels and vitamin B12, along with the complications of celiac disease.

    Among other findings, the study shows that: small bowel capsule endoscopy reveals macroscopic changes in celiac disease patients with a high level of sensitivity; low levels of vitamin B12 and folate due to malabsorption match the severity of celiac disease; celiac patients with a normal small bowel capsule endoscopy result are not likely to have significant active disease.

    Wondering how many other celiacs also have restless legs due to malabsorption? I get monthly shots of B vitamins, folate, and magnesium. Oral supplements help very little. I take an Rx but need to do both the shots and pramperaxole to sleep well.

    OBJECTIVE: Although coeliac disease is a disorder of the proximal small bowel, associated vitamin B12 deficiency has been reported. This study aimed to assess the prevalence of B12 deficiency in a large series of coeliac patients, and to exclude the possibility that it is due to...

    Celiac.com 06/17/2015 - Refractory celiac disease type II (RCDII) and EATL (Enteropathy Associated T-cell Lymphoma) are pre-malignant complications of celiac disease. However, there is scant medical literature and data what role malnutrition and intestinal absorption may play in these conditions.
    With this in mind, a team of researchers set out to conduct a comprehensive assessment of nutritional status and intestinal absorption capacity of patients with RCDII and EATL, and to compare that with data of newly diagnosed celiac disease patients. The research team included N.J. Wierdsma, P. Nijeboer, M.A. de van der Schueren, M. Berkenpas, A.A. van Bodegraven...

    Celiac.com 04/12/2016 - Vitamin B12 is a group of cobalt containing compounds described by Alan R. Gaby, M.D. in Nutritional Medicine called cobalamins. Methylcobalamin is the coenzyme form of B12 that is critical for human health. Hydroxocobalamin is a more stable form of B12 but it first needs to be converted to an active form before use in metabolism.
    Vitamin B12 is important in DNA synthesis, red blood cell formation, homocysteine metabolism and the production of S-adenosylmethionine (SAMe). Adequate B12 is essential for proper neurological and immune function.
    The importance of Vitamin B12 in health and anemia management began during the Depression...
