Genotype-Guided Thiopurine Dosing Does not Lead to Additional Costs in Patients With Inflammatory Bowel Disease

Abstract Background and Aims Decreased thiopurine S-methyltransferase [TPMT] enzyme activity increases the risk of haematological adverse drug reactions [ADRs] in patients treated with thiopurines. Clinical studies have shown that in patients with inflammatory bowel disease [IBD], pharmacogenetic TPMT-guided thiopurine treatment reduces this risk of ADRs. The aim of this study was to investigate whether this intervention impacts on healthcare costs and/or quality of life. Methods An a priori defined cost-effectiveness analysis was conducted in the Thiopurine response Optimization by Pharmacogenetic testing in Inflammatory bowel disease Clinics [TOPIC] trial, a randomized controlled trial performed in 30 Dutch hospitals. Patients diagnosed with IBD [age ≥18 years] were randomly assigned to the intervention [i.e. pre-treatment genotyping] or control group. Total costs in terms of volumes of care, and effects in quality-adjusted life years [QALYs], based on EuroQol-5D3L utility scores, were measured for 20 weeks. Mean incremental cost savings and QALYs with confidence intervals were calculated using non-parametric bootstrapping with 1000 replications. Results The intervention group consisted of 381 patients and the control group 347 patients. The mean incremental cost savings were €52 per patient [95% percentiles −682, 569]. Mean incremental QALYs were 0.001 [95% percentiles −0.009, 0.010]. Sensitivity analysis showed that the results were robust for potential change in costs of screening, costs of biologicals and costs associated with productivity loss. Conclusions Genotype-guided thiopurine treatment in IBD patients reduced the risk of ADRs among patients carrying a TPMT variant, without increasing overall healthcare costs and resulting in comparable quality of life, as compared to standard treatment.

Introduction: Inflammatory bowel disease is a chronic disease with a fluctuating course and unknown origin. Its two major forms are Crohn’s disease and ulcerative colitis. Objective: The authors attempted to analyse the quality of life of patients with inflammatory bowel disease as compared to healthy persons and patients with asthma in order to identify specific factors which most significantly affect the quality of life of these patients. Method: 269 subjects participated in the study (control group, 115 subjects; Crohn’s disease, 67 patients; ulcerative colitis, 25 patients; asthma, 62 patients). The following methods were used: WHO-5, IIRS, SIBDQ and AQLQ(S) questionnaires and content analysis. Results: Patients with inflammatory bowel disease had the worst quality of life with respect to both subjective well-being and burden of disease. The results obtained from questionnaires developed for the analysis of quality of life indicated that extraintestinal symptoms and emotional problems are the major factors which interfere with the quality of life of patients with inflammatory bowel disease. These findings were confirmed by content analysis of interviews with patients. Conclusions: The authors recommend that more attention should be paid to improving the quality of life of patients with inflammatory bowel disease and helping them to live with the illness, especially at the level of interpersonal relations.

The Impact

Background. Patients with inflammatory bowel disease (IBD) have a high prevalence of emotional disturbances which worsen the symptoms of the disease. As a therapeutic alternative that is part of a comprehensive care alongside medication, the Bonny Method of Guided Imagery and Music (BMGIM) music-assisted therapy has achieved promising emotional improvements in patients with chronic diseases. The objective of the study was to determine the impact of a treatment based on a BMGIM group adaptation on patients with inflammatory bowel disease (IBD) and their emotional state, therefore analyzing state of mind, quality of life, anxiety, depression, immunocompetence as a marker of well-being, and levels of acute and chronic stress. Methods. Longitudinal, prospective, quantitative, and experimental study including 43 patients with IBD divided into an intervention group (22 patients), who received eight sessions over eight weeks, and a control group (21 patients). A saliva sample was taken from each patient before and after each session in order to determine cortisol and IgA levels. Similarly, a hair sample was taken before the first and after the last session to determine the cumulative cortisol level. All molecules were quantified using the ELISA immunoassay technique. In addition, patients completed several emotional state questionnaires: HADS, MOOD, and CCVEII. Results. An improvement was observed in the following states of mind: sadness, fear, anger, and depression. No significant effect was observed in state of mind in terms of happiness or anxiety, in the levels of cortisol in hair, and in patients’ perceived quality of life. A reduction in cortisol was observed in saliva, although this did not significantly affect the IgA titer. Conclusions. BMGIM seems to improve the emotional state of patients with IBD.
