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.

Short-term moderate exercise programs reduce oxidative DNA damage as determined by high-performance liquid chromatography-electrospray ionization-mass spectrometry in patients with colorectal carcinoma following primary treatment.

OBJECTIVE: Oxidative DNA damage is believed to be involved in tumor formation and may be an important biomarker for malignant transition or relapse. A decrease of such damage has been observed in human and animal studies following dietary intervention and/or changes in lifestyle such as physical exercise at different levels of intensity. The purpose of this study was to carry out a clinical trial comparing the effects of a short-term (2 weeks) exercise program of moderate intensity (0.3-0.4 x maximal exercise capacity) (MI) versus high intensity (0.5-0.6 x maximal exercise capacity) (HI) on individual urinary excretion of 8-oxo-dG before and after completion of the exercise programs. MATERIAL AND METHODS: In this short-term, prospective and randomized trial, 19 patients with colorectal cancer were allocated to the MI group following primary therapy and 29 to the HI group. Urinary 8-oxo-dG excretion concentration was determined by a highly sensitive detection method using high-performance liquid chromatography coupled to electrospray ionization mass spectrometry (HPLC-ESI-MS). Concentrations were determined immediately before and after completion of the exercise programs. RESULTS: Using HPLC-ESI-MS, it was shown that MI exercise significantly reduced urinary 8-oxo-dG excretion levels from 8.47 +/- 1.99 to 5.81 +/- 1.45 (ng/mg creatinine, mean +/- SE, p = 0.02), whereas HI exercise resulted in a non-significant increase from 5.00 +/- 1.31 to 7.11 +/- 1.63 (ng/mg creatinine, p = 0.18). Clinical characteristics (gender, age, body mass index (BMI), diet, chemotherapy/irradiation) were not associated/correlated with urinary 8-oxo-dG levels. CONCLUSIONS: By using HPLC-ESI-MS it was shown that short-term MI exercise after primary therapy in patients with colorectal cancer was associated with lower levels of urinary 8-oxo-dG, suggesting decreased oxidative DNA damage. In contrast, HI exercise tended to increase DNA damage. A prospective trial is now warranted to prove that reduced oxidative DNA damage lowers the risk of relapse of colorectal cancer in treated patients.
