Purpose Mesalazine and sulfasalazine are commonly used drugs for the treatment of inflammatory bowel disease. However, there have been few reports with a strict statistical analysis comparing the effects of mesalazine and sulfasalazine on laboratory test results. Therefore, we designed a retrospective cohort study to investigate whether or not differences in clinical laboratory parameters exist between mesalazine and sulfasalazine users. Methods We used data from the Clinical Data Warehouse of Nihon University School of Medicine to identify cohorts of new mesalazine users (n = 303) and sulfasalazine users (n = 67). We used a multivariate regression model and regression adjustment with the propensity score to adjust for differences in baseline covariates between mesalazine and sulfasalazine users, and compared serum levels of creatinine, urea nitrogen, aspartate aminotransferase, alanine aminotransferase, and hematological parameters including red and white blood cell counts and platelet count. Results After adjustment, in sulfasalazine users, the mean values for all tests showed no significant change between baseline and during the exposure period. In contrast, in mesalazine users, the mean WBC and platelet counts during the exposure period were significantly lower than those at baseline. Furthermore, mean serum urea nitrogen level during the exposure period was significantly higher than that at baseline. In terms of mean changes in laboratory test values during the exposure period compared with baseline, the reduction of platelet count in mesalazine users was significant in comparison to that in sulfasalazine users. Conclusion Our findings suggested that the hematological adverse effects of mesalazine treatment might be greater than those of sulfasalazine treatment.

A micropropagation protocol was developed for multiplication of seedless lemon (Citrus limon L. cv. Kaghzi Kalan) using nodal explants. The maximum shoot regeneration was observed on low level of BAP (0.1 mg l−1) or kinetin (0.5 mg l−1). BA was recorded to be better than kinetin in terms of ... more
The objective of this study was to evaluate the activity, kinetic behavior, and thermal inactivation kinetics of peroxidase (POD) in aqueous extracts from two kinds of milk ripe stage corn, sweet corn and waxy corn. Optimum activities using guaiacol as the hydrogen donor were obtained for s ... more
