Mucosal atrophy in collagenous colitis: a case report.

BACKGROUND: Mucosal atrophy as a potential cause of impaired colonic compliance has not yet been described as a complication in Collagenous Colitis (CC). CASE PRESENTATION: We present a 51-year-old female patient with a 20-year history of diarrhea and diagnosed with CC ten years prior to her presentation. We reviewed reports from three colonoscopies performed after the diagnosis. Overall 12 biopsies obtained in the last two colonoscopies were re-analyzed by two pathologists blinded to the aim of the study. Besides the typical histological findings of CC, the endoscopic appearance was normal, and no histological signs of atrophy were found during the first colonoscopy. Surprisingly, the second and third colonoscopy revealed a region of advanced segmental mucosal atrophy in the cecum with the mucosal height normalizing toward the transverse colon. This pattern of atrophy was inversely related to the pattern of sub-epithelial collagen deposition, which increased toward the rectum. CONCLUSION: If no chance occurrence, our observation supports the idea that additional factors, probably luminal in nature, may be co-responsible for the mucosal atrophy in this case. Thus, mucosal atrophy in the proximal colon appears to be a new candidate among the growing list of rare complications associated with long standing CC.

Appropriateness of Crohn's disease therapy in gastroenterological rehabilitation.

BACKGROUND/AIMS: The treatment criteria developed by the European Panel on the Appropriateness of Crohn's Disease (CD) Therapy (EPACT) have not been applied to rehabilitation. Thus, we retrospectively evaluated appropriateness of treatments during CD rehabilitation using the EPACT website. METHODS: We included our 1-year inpatient rehabilitation patients that had been assigned the International Classification of Disease Code for CD. The appropriateness of treatment was assessed in CD categories exhibiting frequent treatment changes. Treatment plans were compared to EPACT recommendations. RESULTS: Charts of 337 proven CD patients (median age 42 [range 17-65] years, 250 women, median Crohn's Disease Activity Index 140 [range -3 to 427] units) were assigned to EPACT categories. The categories 'steroid-dependent' and 'steroid-refractory' exhibited frequent treatment changes. In these 59 patients, 16 treatments (13 azathioprine, 1 methotrexate, 2 infliximab) were rated as appropriate. One certolizumab treatment was uncertain. 22 treatments with azathioprine were inappropriate (21 due to underdosing), and 93 treatments (30 mesalamine, 59 steroid, 4 budesonide) were not rated. The number of differences between treatment plans and EPACT recommendations decreased from 45 to 25 in both CD categories (p < 0.0001). CONCLUSIONS: We introduce the EPACT website as a practical advance towards an optimal therapy in rehabilitants with steroid-dependent or -refractory CD.

Linking Crohn's disease health status measurements with International Classification of Functioning, Disability and Health and vocational rehabilitation outcomes.

OBJECTIVE: The International Classification of Functioning, Disability and Health (ICF) serves as a unifying model for rehabilitation medicine. Variables of the health status measurements, the Crohn's Disease Activity Index and the Harvey-Bradshaw Index, have not been linked with the ICF categories and compared with other predictors of rehabilitation outcomes. METHODS: Crohn's Disease Activity Index variables were linked with ICF categories using linking rules. A chart review included the patients of our in-patient rehabilitation centre during one year (n=355) with International Classification of Disease Codes for Crohn's disease (ICD K50). We identified variables linked with clinical improvement (decrease in the Harvey-Bradshaw Index of > or = 2 U) and rehabilitation success (conversion from unfit-to-work to fit-to-work) by multivariate logistic regression. RESULTS: The ICF component, activities and participation, was not represented in the Crohn's Disease Activity Index and the Harvey-Bradshaw Index. A Harvey-Bradshaw Index > or = 5 U was associated with clinical improvement during rehabilitation (odds ratio 5.65 (95% CI 3.41-9.35)). Normal C-reactive protein (odds ratio 2.8 (95% CI 1.1-7.0)) and higher body mass index (odds ratio (per 1 kg/m2 increase) 1.1 (95% CI 1.0-1.2)), but not Harvey-Bradshaw Index, were associated with vocational rehabilitation success in 124 patients who were initially unfit-to-work. CONCLUSION: Variables representing activities and participation as well as immune functions may improve Crohn's disease health status measurements on the basis of better prediction of vocational rehabilitation success.
