Phenotype of histologically suspected drug-induced colitis; results of a comparative, retrospective cohort study
2019
AbstractBackground/aims: Drug-induced colitis (DiC) is a rarely reported form of colonopathy and data about the clinical and endoscopic characteristics are scarce. The aim was to investigate the phenotype of DiC.Methods: Patients in a retrospective case control study were assigned to either DiC or one of two age- and gender-matched control groups (non-inflammatory controls and inflammatory colitis from other causes) based on histopathological findings. Patients’ basic characteristics, symptoms, biochemical results and endoscopic appearance were collected. Statistical analysis included ANOVA, the chi-squared test and two-tailed t-test.Results: A total of 211 patients with DiC were included (97 males, age 62.1 ± 16.1 years, BMI 25.9 ± 6.1 kg m−2). In comparison to both control groups, DiC patients presented higher ASA and ECOG-scores and more particularly atherosclerotic comorbidities. The most abundant symptoms were abdominal pain (51.8%), diarrhoea (50.7%) and haematochezia (24.3%). The red blood cell cou...
