We report a case of T1DM with poor glycaemic control and recurrent episodes of hypoglycaemias and diabetic ketoacidosis (DKA). Recurrent oromucosal and respiratory infections further complicated the course of illness, resulting in the increasing proneness to DKA. The patient was screened for coeliac disease but the IgA-based screening test was negative (IgA tissue transglutaminase) due to the low IgA level, whereas the IgG antigliadin was positive. The patient benefited from initiation of a gluten-free diet.<\/jats:p>","DOI":"10.1136\/bcr-2013-200472","type":"journal-article","created":{"date-parts":[[2013,11,8]],"date-time":"2013-11-08T10:19:04Z","timestamp":1383905944000},"page":"bcr2013200472","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Curious case of missing (A) in coeliac disease with type 1 diabetes mellitus"],"prefix":"10.1136","volume":"2013","author":[{"given":"Ameya S","family":"Joshi","sequence":"first","affiliation":[{"name":"Department of Endocrinology, Topiwala National Medical College and BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Premlata K","family":"Varthakavi","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Topiwala National Medical College and BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikhil M","family":"Bhagwat","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Topiwala National Medical College and BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pradip","family":"Dalwadi","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Topiwala National Medical College and BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,11,8]]},"reference":[{"key":"2025082805225293000_2013.nov08_1.bcr2013200472.1","doi-asserted-by":"crossref","first-page":"161285","DOI":"10.1155\/2010\/161285","article-title":"Celiac disease and pediatric type 1 diabetes: diagnostic and treatment dilemmas","volume":"2013","author":"Sud","year":"2010","journal-title":"Int J Ped Endocrinol"},{"key":"2025082805225293000_2013.nov08_1.bcr2013200472.2","first-page":"1295","article-title":"Celiac disease and immunoglobulin A deficiency: how effective are the serological methods of diagnosis?","volume":"2013","author":"Kumar","year":"2002","journal-title":"Clin Diagn Lab Immunol"},{"key":"2025082805225293000_2013.nov08_1.bcr2013200472.3","doi-asserted-by":"crossref","first-page":"362","DOI":"10.1136\/gut.42.3.362","article-title":"Prevalence and clinical features of selective immunoglobulin A deficiency in coeliac disease: an Italian multicentre study.
