Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: Recent years have seen significant research advances within the gastroenterological field. Some of these consist of the recognition of serrated polyps as a precursor to colorectal cancer, and the realization of the health economic burden associated with gastrointestinal diseases.Aim: In this thesis, we aim to validate the specificity of serrated polyps in the ESPRESSO cohort (Paper I). We also aim to estimate work loss in patients with celiac disease, including the temporal relationship of work loss before and after diagnosis (Paper II).Method: By using the ESPRESSO cohort, we collected data on patients with serrated polyps and patients with celiac disease. In Paper I, the specificity of serrated polyps in the ESPRESSO cohort were validated by a structured retrospective review of patient chart. In Paper II, we estimated work loss in patients with celiac disease as compared withgeneral-population comparators matched on age, sex, county of residence and year of diagnosis.Result: The presence of a serrated polyp was confirmed in 101 out of 106 individuals identified through the ESPRESSO cohort, yielding a positive predictive value of 95% (95% confidence interval: 89-98%). Patients with celiac disase had 42.5 lost work days as compared to 28.6 days in comparators (mean difference, 14.7; 95% confidence interval, 13.2-16.2), corresponding to a relative increase of 49%. Excess work loss in patients with celiac disease was observed even 5 years before diagnosis and remained eleveated during the years after diagnosis this loss. Notebly, the excess work loss was concentrated to a small proportion while most celiac patients did not have any work loss before or after diagnosis. Conclusion: The ESPRESSO cohort has a high specificity for serrated polyps. Patients with celiac disease miss more work days than the general population even before diagnosis, and this loss persists after diagnosis.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Celiac disease (CD) is an immune‐mediated disease triggered by gluten intake and affects around 1% of the population worldwide. Although patients with CD have an increased use of healthcare, data on work disability remains scarce. To estimate work loss in patients with CD before and after diagnosis. We identified 16,005 working‐age patients with prevalent CD, and 4,936 incident working‐age patients diagnosed in 2008‐2015 through biopsy reports from Sweden’s 28 pathology departments. CD was defined by presence of villus atrophy (Marsh 3) on biopsy (gold standard). Each patient was compared to up to 5 matched general‐population comparators. Using nationwide social insurance registers, we retrieved prospectively‐recorded data on compensation for sick leave and disability. In 2015, patients with prevalent CD had a mean of 42.5 (95%CI: 40.9‐44.1) lost work days as compared with 28.6 (27.9‐29.2) in the general‐population comparators, corresponding to a relative difference of 49%. Among incident patients, the annual mean difference between patients and comparators was 8.0 (5.4‐10.6) lost work days 5 years before CD diagnosis, which grew to 13.7 (9.1‐18.3) days 5 years after diagnosis. In addition to the continuously increasing mean difference in lost work days over time, there was also a transient increase in work loss in patients with CD during the year of diagnosis (mean difference: 15.6 days, 95%CI: 13.1‐18.0). Patients with CD miss more work days than comparators before their diagnosis, and this loss increases and persists after diagnosis despite presumed installation of treatment with gluten‐free diet.
