    Celiac.com 10/20/2014 - Researchers don’t have much data on rates of celiac disease in patients with autoimmune hepatitis (AIH). To better understand any connections between the two conditions, a Dutch research team recently set out to examine the rates of celiac disease in patients with autoimmune hepatitis.

    Specifically, the team set out to investigate the relationship between AIH and celiac disease by assessing the prevalence of IgA tissue antitransglutaminase antibodies (TGA) and antiendomysium antibodies (EMA) in a large group of AIH patients.

    The research team N.M. van Gerven, S.F. Bakker, Y.S. de Boer, B.I. Witte, H. Bontkes, C.M. van Nieuwkerk, C.J Mulder, G. Bouma; and the Dutch AIH working group. They are variously affiliated with the Departments of Gastroenterology and Hepatology, Epidemiology and Biostatistics, and Medical Immunology at the VU University Medical Centre in Amsterdam, The Netherlands.

    For the first step in their study, the team used TGA antibody serology to determine the frequency of celiac disease in a group of 460 AIH patients. The team conducted EMA screens on any patients showing TGA positivity.

    They then used digital and written medical records to collect retrospective data on previously diagnosed celiac disease and patient characteristics, and compared those findings with archival data on the prevalence of celiac disease in the Netherlands. They found that six patients had a known history of celiac disease, but were currently in remission, as shown by negative TGA blood screens.

    In addition, ten of the 460 AIH patients (2.2%) showed positive IgA TGA. Positive EMA antibodies in these patients served to confirm celiac disease diagnosis.

    Overall, the team found celiac disease in 3.5% of AIH patients compared with just 0.35% in the general Dutch population (P<0.001).

    Discounting patients with either a primary biliary cirrhosis or primary sclerosing cholangitis overlap, the team found celiac disease in 11 (2.8%) AIH patients. This is the largest serological study to examine connections between AIH and celiac disease, and shows that patients with AIH have rates of celiac disease that are higher than those of the general population, but not as high as some studies have suggested.

    Still, the team advises doctors to consider the possibility of concurrent celiac disease in all AIH patients.

    Celiac.com 06/26/2007 - In a study published recently in the Scandinavian Journal of Gastroenterology, researchers found that celiac patients commonly have high rates of anti-Saccharomyces cerevisiae antibodies (ASCA). A team of researchers recently set out to assess the frequency anti-Saccharomyces cerevisiae antibodies (ASCA) in patients with celiac disease.
    The team was made up of Dorsaf Toumi; Amani Manka&IUML;; Ramla Belhadj; Leila Ghedira-Besbes; Moncef Jeddi; and Ibtissem Ghedira. They used ELISA to evaluate blood serum for ASCA, IgG and IgA in 238 patients with celiac disease. The team used 80 non-celiac blood donors as a control...

    Celiac.com 06/13/2012 - In general, doctors and researchers know a good deal about how celiac disease works, and they are finding out more all the time. However, they know very little about non-celiac gluten sensitivity (NCGS).
    In an effort to learn more about non-celiac gluten sensitivity, a team of researchers recently carried out a study to measure the presence of somatization, personality traits, anxiety, depression, and health-related quality of life in NCGS individuals, and to compare the results with celiac disease patients and healthy control subjects. They also compared the response to gluten challenge between patients with non-celiac gluten...

    Celiac.com 06/29/2012 - A group of researchers recently set out to study cases of positive tissue transglutaminase antibodies with negative endomysial antibodies to determine whether or not such cases amount to celiac disease.
    The team included Thomas Hornung; Pavel Gordins; Clare Parker; and Nicholas Thompson. They are variously affiliated with the departments of Gastroenterology, and Immunology at the Northern Deanery of Newcastle upon Tyne, and with the department of Gastroenterology at Freeman Hospital in Newcastle upon Tyne in the UK.

    A team of researchers recently took a look at how well the hepatitis B vaccine protected people with celiac disease over time. Specifically, they evaluated what is called long-term antibody persistence and immune memory to hepatitis B virus in adult celiac patients vaccinated as adolescents.
    The research team included F. Zingone, F. Morisco, A. Zanetti, L. Romanò, G. Portella, P. Capone, P. Andreozzi, R. Tortora, and C.Ciacci. They are affiliated with the Department of Clinical and Experimental Medicine of Federico II University of Naples in Italy.
