On the other hand, in the case of cabazitaxel, a decrease in Alb levels may lead to an increased proportion of unbound drug at the same dose, which could potentially raise the risk of developing severe neutropenia. Therefore, in this study, we investigated the usefulness of a novel index, the cabazitaxel dose divided by the Alb level (Dose/Alb), as a more accurate predictor of severe neutropenia in patients with metastatic castration-resistant prostate cancer receiving cabazitaxel. Thirty-nine patients were divided into two groups: 14 patients with grade 3-4 neutropenia and 25 with grade 0-2 neutropenia. Dose/Alb at the initiation of cabazitaxel was significantly higher in the grade 3-4 neutropenia group than in the grade 0-2 group (<i>P</i> = 0.013).

The primary endpoint was the difference in accuracy over time of the estimated Clcr/GFR relative to the measured Clcr. The CG equation was used to estimate Clcr, and the MDRD and CKD-EPI-equations were used to estimate GFR. Estimated Clcr(round-up)/GFR(round-up) indicates the estimated Clcr/GFR calculated using the rounded up value if SCr was <0.6 mg/dL.

The CKD-EPI equation showed a large underestimation bias in the early period, whereas the CG and MDRD equations indicated large overestimation biases in the later period. Round-up correction increased the underestimation bias in the early period of the CG(round-up) and MDRD(round-up) equations, but decreased the overestimation bias in the later period. The limits of agreements for the CG(round-up) and MDRD(round-up) equations were narrower, although not consistently acceptable.

This study investigated the effect of famotidine on blood carnitine concentrations and L-carnitine supplementation requirements in tube-fed patients with SMID. <i>Methods:</i> A retrospective observational study including patients receiving exclusive enteral nutrition and L-carnitine supplementation was conducted at the Tokyo Metropolitan Tobu Medical Center.

A correlation between L-carnitine dose and free carnitine level was observed only among non-users of famotidine (correlation coefficient: 0.352). Additionally, 36.8% of famotidine users exhibited persistently low free carnitine levels despite supplementation, compared to 3.9% of non-users. <i>Conclusion:</i> Famotidine use was associated with increased L-carnitine supplementation requirements, likely due to impaired renal carnitine reabsorption. Routine monitoring of famotidine-treated patients may help prevent L-carnitine deficiency.

In the disproportionality analysis, we applied the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma-Poisson shrinker (MGPS) algorithms for signal detection. The time to onset of AEs was assessed using Kaplan-Meier curves and the Weibull distribution test. <i>Results:</i> The analysis encompassed 40,265 AEs reports from FAERS and 4,330 from JADER. Mesalazine-related preferred terms (PTs) mapped to 27 System Organ Classes (SOCs) in FAERS and 25 SOCs in JADER. Gastrointestinal disorders emerged as the most frequently reported SOC in both databases. Three SOCs demonstrated significant signal strength across both datasets: (1) gastrointestinal disorders, (2) general disorders and administration site conditions, and (3) respiratory, thoracic, and mediastinal disorders. Common AEs including diarrhœa, pancreatitis, gastroenteritis, asmyopericarditis, proctitis ulcerative, and glutamate dehydrogenase level abnormal aligned with established drug labeling.
