Abstract
Darbā gaitā izvērtēta kombinētas seroloģiskās un ģenētiskās secīgas izmeklēšanas loma celiakijas diagnostikā, kā arī noteikta celiakijas sastopamība Latvijas populācijā, ņemot vērā seroloģisko un ģenētisko izmeklējumu rezultātus.
Metodes: Celiakijai raksturīgās antivielas tika noteiktas 1443 pacientiem. 43 seropozitīvajiem veikta arī celiakijas genotipa noteikšana. Aptuveni piecas reizes vairāk seronegatīvajiem paraugiem arī tika noteikts HLA-DQ genotips.
Rezultāti: Ar seroģenētisko metodi noteiktā celiakijas prevalence Latvijas populācijā ir no 0,28% līdz 1,25%. Rezultāti atkarīgi no aprēķinos izmantotajiem kritērijiem, taču visprecīzāk noteiktā ir 0,42%.Viltus pozitīvi seroloģisko testu rezultāti ir līdz 58% gadījumu.

A role of combined serologic and genetic algorithm for the diagnosticēs of Celiac Disease as well as prevalence of the autoimmune condition in Latvian adult population has been presented. Methods: Serologic testing for Celiac Disease antibodies was performed for a total of 1443 subjects. For 43 seropositive subjects genotyping was performed to determine the status of HLA-DQ. Randomly chosen (at a ratio of 1:5) seronegative subjects were also genotyped. Results: Serogenetic prevalence of Celiac Disease in Latvian adult population is between 0,28% and 1,25%. The results vary depending on the criteria applied, and the most accurate estimate would be 0,42%. False positive serologic test results were detected in up to 58% cases. Keywords: Celiac Disease, Prevalence, HLA-DQ, serology.
