BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) who have been exposed to thiopurines might have an increased risk of skin cancer. We assessed this risk among patients in France. METHODS We performed a prospective observational cohort study of 19,486 patients with IBD, enrolled from May 2004 to June 2005, who were followed up until December 31, 2007. The incidence of nonmelanoma skin cancer (NMSC) in the general population, used for reference, was determined from the French Network of Cancer Registries. RESULTS Before the age of 50 years, the crude incidence rates of NMSC among patients currently receiving or who previously received thiopurines were 0.66/1000 and 0.38/1000 patient-years, respectively; these values were 2.59/1000 and 1.96/1000 patient-years for the age group of 50 to 65 years and 4.04/1000 and 5.70/1000 patient-years for patients older than 65 years. Among patients who had never received thiopurines, the incidence of NMSC was zero before the age of 50 years, 0.60/1000 for the ages of 50 to 65 years, and 0.84/1000 for those older than 65 years. A multivariate Cox regression model stratified by propensity score quintiles showed that ongoing thiopurine treatment (hazard ratio [HR], 5.9; 95% confidence interval [CI], 2.1-16.4; P = .0006) and past thiopurine exposure (HR, 3.9; 95% CI, 1.3-12.1; P = .02) were risk factors for NMSC. They also identified age per 1-year increase as a risk factor for NMSC (HR, 1.08; 95% CI, 1.05-1.11; P < .0001). CONCLUSIONS Ongoing and past exposure to thiopurines significantly increases the risk of NMSC in patients with IBD, even before the age of 50 years. These patients should be protected against UV radiation and receive lifelong dermatologic screening.

Aminosalicylates are first‐choice treatment for mild‐to‐moderately active ulcerative colitis (UC); however, multi‐dosing regimens are inconvenient.

7-3589). There was no impact of years of 5ASA use on outcomes. Conclusion In study I we could not find evidence that 1 or 5 years of consecutive 5-ASA use was chemoprophylactic in IBD (in fact it tended to increase the risk). We could not discount that longer use might have been chemoprophylactic. In Study II with a longer duration of follow up and more CRC cases we could not discern that 5-ASA was chemoprophylactic. Overall, our results support the majority of studies to date that 5-ASA is not chemoprophylactic in IBD for CRC.

Purpose: To develop a self-administered questionnaire assessing patients’ satisfaction with treatments in Crohn’s disease for use in clinical research and epidemiological studies. Patients and methods: Semi-directive interviews (16) were conducted with patients with severe Crohn’s disease treated with anti-tumor necrosis factor alpha (anti-TNFα). Transcripts were analyzed and concepts related to satisfaction with treatment were extracted and organized into a model. Items were generated using patients’ words. The resulting test version was tested for relevance and comprehension with 7 patients and revised accordingly; the new version was tested with 5 other patients and revised to provide the pilot version. A clinician advisory board was involved at each milestone of the development. Results: The test questionnaire assessed treatment satisfaction through 67 items, organized into 5 sections: treatment efficacy, side-effects, convenience and constraints, overall impact, and satisfaction. Conceptual content of the questionnaire includes comparison with prior state and with expectations, satisfaction, acceptability, and intentions. The questionnaire was generally well accepted and understood by patients; few modifications were made in the structure and item formulation. After the second round of comprehension tests, the pilot version contained 62 items; the questionnaire was named Satisfaction of PAtients in Crohn’s diseasE (SPACE©). Conclusion: The questionnaire is a unique tool to assess treatment satisfaction in patients with Crohn’s disease. A scoring and validation study is currently being performed to finalize and establish its scoring, as well as its psychometric properties.

Background Severe Crohn’s disease management includes anti-tumor necrosis factor (anti-TNF) drugs that differ from early-stage treatments regarding efficacy, safety, and convenience. This study aimed to finalize and psychometrically validate the Satisfaction for PAtients in Crohn’s diseasE Questionnaire (SPACE-Q©), developed to measure satisfaction with anti-TNF treatment in patients with severe Crohn’s disease. Methods A total of 279 patients with severe Crohn’s disease receiving anti-TNF therapy completed the SPACE-Q 62-item pilot version at inclusion and 12 and 13 weeks after first anti-TNF injection. The final SPACE-Q scoring was defined using multitrait and regression analyses and clinical relevance considerations. Psychometric validation included clinical validity against Harvey–Bradshaw score, concurrent validity against Treatment Satisfaction Questionnaire for Medication (TSQM), internal consistency reliability, test–retest reliability, and responsiveness against the patient global impression of change (PGIC). Results Quality of completion was good (55%–67% of patients completed all items). Four items were removed from the questionnaire. Eleven scores were defined within the final 58-item SPACE-Q: disease control; symptoms, anal symptoms, and quality of life transition scales; tolerability; convenience; expectation confirmation toward efficacy, side effects, and convenience; satisfaction with treatment; and motivation. Scores met standards for concurrent validity (correlation between SPACE-Q satisfaction with treatment and TSQM satisfaction scores =0.59), internal consistency reliability (Cronbach’s α=0.67–0.93), test–retest reliability (intraclass correlations =0.62–0.91), and responsiveness (improvement in treatment experience assessed by the SPACE-Q for patients reporting improvement on the PGIC). Significantly different mean scores were observed between groups of patients with different Harvey–Bradshaw disease severity scores. Conclusion The SPACE-Q is a valid, reliable, and responsive instrument to measure satisfaction with anti-TNF treatment in patients with severe Crohn’s disease and for use in future studies.

perception of QoC compared with patients’ perception showed that patients scored the care dimension “competence” and “costs” higher and “continuity of care” lower than physicians (Table 1). Conclusions: QoC in this Italian IBD cohort is good, and well compares to previously published results in different European Countries. Physicians’ and patients’ perspectives are similar, although physicians overscore continuity of cares and underscore competence and costs compared to patients. The results of this study may contribute to ameliorate standards of practice in order to optimize QoC for IBD in Italy.
