title: Diagnostic intervals for recognizing celiac disease.
abstract: The aim of this retrospective study was to determine the time intervals between the onset of symptoms and diagnosis of celiac disease on the basis of a questionnaire that was published in the journal of the German Celiac Society (Verbandszeitschrift der Deutschen Zöliakie-Gesellschaft). 408 adult patients in whom the diagnosis of celiac disease was made after the age of 15 responded to the questionnaire. The time interval between the onset of symptoms and diagnosis (total diagnostic interval) was 5.4 (median) and 10.1 +/- 12.3 (mean +/- SD) years, interval-1 (time interval between the onset of symptoms and the first visit to a doctor) was 0.4 (median) and 2.2 +/- 6.6 (mean +/- SD) years, and interval-2 (time interval between the first visit to a doctor and the diagnosis) was 3.9 (median) and 8.0 +/- 10.4 (mean +/- SD) years. The time intervals shortened only a little over the years. At all times, interval-2 was significantly longer than interval-1. There were no differences between female (n = 328) and male (n = 80) patients and between the age groups. Furthermore, none of the gastrointestinal and non-gastrointestinal symptoms had had a distinct influence on all diagnostic intervals and also the fact that other family members having the disease did not shorten any of the intervals. In summary, the diagnostic intervals for recognizing celiac disease are still unacceptably long. More public awareness work has to be done so that patients can recognize their symptoms and doctors especially can suspect celiac disease sooner and perform the necessary diagnostic procedures when patients present with suggestive symptoms.
