Still, the exact global prevalence of celiac disease remains unknown. To get better data on that issue, a team of researchers recently conducted a comprehensive review and meta-analysis to get a reasonably accurate estimate the global prevalence of celiac disease. The research team included P Singh, A Arora, TA Strand, DA Leffler, C Catassi, PH Green, CP Kelly, V Ahuja, and GK Makharia. They are variously affiliated with the Division of Gastroenterology and Hepatology, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Lady Hardinge Medical College, New Delhi, India; Innlandet Hospital Trust, Lillehammer, Norway; Centre for International Health, University of Bergen, Bergen, Norway; Division of Gastroenterology and Hepatology, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Gastroenterology Research and Development, Takeda Pharmaceuticals Inc, Cambridge, MA; Department of Pediatrics, Università Politecnica delle Marche, Ancona, Italy; Department of Medicine, Columbia University Medical Center, New York, New York; USA Celiac Disease Center, Columbia University Medical Center, New York, New York; and the Department of Gastroenterology and Human Nutrition, All India Institute of Medical Sciences, New Delhi, India. For their review, the team searched Medline, PubMed, and EMBASE for the keywords ‘celiac disease,’ ‘celiac,’ ‘tissue transglutaminase antibody,’ ‘anti-endomysium antibody,’ ‘endomysial antibody,’ and ‘prevalence’ for studies published from January 1991 through March 2016. The team cross-referenced each article with the words ‘Asia,’ ‘Europe,’ ‘Africa,’ ‘South America,’ ‘North America,’ and ‘Australia.’ They defined celiac diagnosis based on European Society of Pediatric Gastroenterology, Hepatology, and Nutrition guidelines. The team used 96 articles of 3,843 articles in their final analysis. Overall global prevalence of celiac disease was 1.4% in 275,818 individuals, based on positive blood tests for anti-tissue transglutaminase and/or anti-endomysial antibodies. The pooled global prevalence of biopsy-confirmed celiac disease was 0.7% in 138,792 individuals. That means that numerous people with celiac disease potentially remain undiagnosed. Rates of celiac disease were 0.4% in South America, 0.5% in Africa and North America, 0.6% in Asia, and 0.8% in Europe and Oceania; the prevalence was 0.6% in female vs 0.4% males. Celiac disease was significantly more common in children than adults. This systematic review and meta-analysis showed celiac disease to be reported worldwide. Blood test data shows celiac disease rate of 1.4%, while biopsy data shows 0.7%. The prevalence of celiac disease varies with sex, age, and location. This review demonstrates a need for more comprehensive population-based studies of celiac disease in numerous countries. The 1.4% rate indicates that there are 91.2 million people worldwide with celiac disease, and 3.9 million are in the U.S.A.

Jefferson Adams posted an article in Celiac Disease & Gluten Intolerance ResearchCeliac.com 03/01/2018 - Mortality rates for children under five have been falling steadily for decades. Additionally, there's plenty of data to indicate that rates of celiac disease have been rising in general population. Before doctors understood the role that gluten played in celiac disease, the prognosis for young children with the condition was grim. Since doctors didn't understand the underlying disease, many of these deaths were simply logged as deaths due to wasting or failure to thrive. Could fewer children dying from celiac disease help explain the apparent rise in celiac rates? In an attempt to answer that question, a team of researchers recently set out to to investigate a possible relationship between mortality rates in children under five years old and rates of celiac disease. The research team included F Biagi, A Raiteri, A Schiepatti, C Klersy, and GR Corazza. They are variously affiliated with the First Department of Internal Medicine, Coeliac Centre, and the Biometry and Clinical Epidemiology, Fondazione IRCCS Policlinico San Matteo, University of Pavia, Pavia, Italy. A review of medical literature revealed 27 studies from 17 different countries concerning rates of celiac disease in schoolchildren between 1995 and 2011, 4 studies were performed in Italy. The researchers conducted a meta-analysis of prevalence rates and compared them between specific country under-5 mortality groups, publication year, and age. Over the last twenty years or so, mortality rates for kids under 5 have been decreasing all over the world. This reduction has mirrored an increase of the rates of celiac disease. The Spearman correlation coefficient was -63%, 95% confidence interval -82% to -33% (Pâ€Š<â€Š0.001). The data show that higher mortality rates mirrored lower rates of celiac disease. This finding is confirmed by the meta-analysis of the four Italian studies. Rates of death for children under 5 years of age seem to influence rates of celiac disease in the general population. Basically, less kids dying young contributes to higher celiac disease rates later on. Because gluten-free diet treatment and numerous other developments allow a better survival of children with celiac disease, the number of people with celiac disease will likely increase for some time into the future.

Jefferson Adams posted an article in Celiac Disease Research Projects, Fundraising, Epidemiology, Etc.Celiac.com 06/29/2017 - A team of researchers recently set out to document trends in diagnosis of celiac disease among patients from a single centre from 1958–2014, and and to provide data on rates and numbers of cases in those born in Derby city over 4 decades. The team also sought to explore a possible connection between deprivation and prevalence and characteristics of celiac disease in Asians. The research team included Geoffrey K T Holmes, and A Muirhead. They are affiliated with the Royal Derby Hospital, Derby, UK, and the Department of Public Health, Derby City Council, Derby, UK. The team used National Census information to identify 2,410 adult celiac patients diagnosed in Derby area hospitals. To measure changes in disease rates and individual cases over the study period, the team identified 1,077 patients born within Derby city; 191 of whom were Asian. From 2010–2014, 20 times more patients were diagnosed than during 1975–1979. More than one-quarter of patients (27%) were diagnosed at or above 60â€…years of age. The team noted a low number of diagnoses in young men. They noted also that most women were diagnosed 35 and 45 years of age, which is 15â€…years earlier than men. Young women and elderly patients saw the largest increase in diagnosis rates. In 2014, overall prevalence was 1:188. Prevalence in women was 1:138. Nearly 5 percent of the variation was attributed to deprivation. Diagnosis rates in Asians increased markedly, although only 5 percent were diagnosed at 60â€…years or older, far lower than for whites. The research team calls for more research into the dramatic increase in celiac cases, and the challenges this increase presents for follow-up and new models of care need. They encourage healthcare workers to be alert to the possibility of undiagnosed celiac disease in young men and elderly Asians. They note that a dedicated celiac clinic is helpful for increasing rates of celiac diagnosis. Source: BMJ Open Gastro 2017; 4:e00013. doi:10.1136/bmjgast-2017-000137
