Background/Aims: Mesalazine is an effective drug for treating ulcerative colitis (UC), but causes allergic symptoms in a few cases. Therefore, the objective of this study was to evaluate the usefulness of the drug-induced lymphocyte stimulation test (DLST) for the diagnosis of mesalazine allergy. Methods: Patients with UC treated with mesalazine with or without a history of associated adverse events (AEs) were enrolled at Kyorin University Hospital from July 2016 to April 2017. Results: The DLST was performed in 104 patients with UC, of which 24 had a history of AEs due to mesalazine treatment. The control value of DLST was 337.4±296.3 counts per minute (cpm) in the AE<sup>+</sup> group and 408.0±371.9 cpm in the AE<sup>-</sup> group. The measured value of DLST was 578.8±424.7 cpm in the AE<sup>+</sup> group and 476.5±471.8 cpm in the AE<sup>-</sup> group. The stimulation index (SI) was 243.9%±291.1% in the AE<sup>+</sup> group and 119.8%±53.0% in the AE<sup>-</sup> group. The SI value and DLST positivity were significantly higher in the AE<sup>+</sup> group than in the AE<sup>-</sup> group (P=0.030 and P=0.029, respectively). The test sensitivity and specificity were 0.240 and 0.805, respectively, and the false-positive and false-negative rate was 0.195 and 0.760, respectively. Conclusions: The DLST for mesalazine showed low sensitivity and high specificity, suggesting that it may be useful for the definitive diagnosis of allergy to mesalazine. (Intest Res 2018;16:273-281)

Background/Aims: Oral mesalazine is an important treatment for ulcerative colitis (UC), and non-adherence to mesalazineincreases the risk of relapse. Controlled-release (CR) mesalazine has 2 formulations: tablets and granules. The relative acceptabilitiesof these formulations may influence patient adherence; however, they have not been compared to date. This studyaimed to evaluate the acceptabilities of the 2 formulations of CR mesalazine in relation to patient adherence using a crossoverquestionnaire survey. Methods: UC patients were randomly assigned to 2 groups in a 1:1 ratio. Patients in each group tookeither 4 g of CR mesalazine tablets or granules for 6 to 9 weeks, and then switched to 4 g of the other formulation for a further 6to 9 weeks. The acceptability and efficacy were evaluated by questionnaires, and adherence was assessed using a visual analogscale. The difference in acceptabilities between the 2 formulations and its impact on adherence were assessed. Results: A totalof 49 patients were prospectively enrolled and 33 patients were included in the analysis. Significantly more patients found thetablets to be less acceptable than the granules (76% vs. 33%, P=0.0005). The granules were preferable to the tablets when the 2formulations were compared directly (73% vs. 21%, P=0.004), for their portability, size, and numbers of pills. The adherence ratewas slightly better among patients taking the granules (94% vs. 91%) during the observation period, but the difference was notsignificant (P=0.139). Conclusion: CR mesalazine granules are more acceptable than tablets, and may therefore be a better optionfor long-term medication. (Intest Res 2019;17:87-93)
