Adult Coeliac Disease in Clinical Practice
2006 (English)Doctoral thesis, comprehensive summary (Other academic)
Coeliac disease (CD) is considered to be the result of a complex interplay of intrinsic (genetic) factors and variable extrinsic (environmental) factors. The complex background of CD explains its wide spectrum of clinical manifestations. For a very long time CD was considered more or less a disease of childhood, which was extremely rare in adults. Nowadays we know that CD is one of the most common food intolerance disorders.
An epidemiological study of CD in a geographically defined area of Sweden (Paper1) showed a prevalence of 95.5/ 100 000 inhabitants. Among the associated diseases an especially high incidence of associated thyroid disease, 10.8% was observed.
In a fifteen-year cohort follow up study of all CD-patients residing in the counties of Örebro and Linköping (Paper 2) the total mortality was increased with 38% (SMR 1.38 95% C.I. 0.31-0.83). This was mainly explained by a 48% increased death rate in ischemic heart disease, significant in patients over 65 years (SMR 1.58 95% C.I. 1.00-2.06). However, there was a 47 % lower risk of all malignancies (SIR 0.53 95% C.I. 0.31-0.83).
A cohort of 22 consecutively biopsy-proven adult CD patients (Paper 3), were followed in respect of antibody titres from diagnosis and after 1, 3, 6, and 12 months on a gluten free diet (GFD). All antibody titres fell sharply within one month. Thus excluding a CD diagnosis serologically on a patient who has initiated a GFD by herself is not to recommend.
In another cohort with CD patients (Paper IV) who were diagnosed 8-12 years earlier recommended and who were recommended, the reliability of diet history, serological and biochemical markers to predict the appearance of the small intestinal mucosa were analysed (Paper IV). The history of a strict GFD gave a predictive value of 88% of a mucosa in remission. The values of serological tests (AGA, EmA and tTG) to predict a mucosa in remission were 93% for all.
In CD patients in remission gastro-intestinal symptoms were evaluated with the GSRS questionnaire. Subjects with CD reported significantly more GI-symptoms than a general population sample (p<0.01). This was particularly true for women with CD who scored worse than female controls .By contrast men with CD reported no more symptoms than male controls.
