A search in EudraVigilance showed a disproportionality for bullous pemphigoid and gliptins, except alogliptin. These findings extend the evidence associating gliptins with this potentially serious disease.

Summary We retrospectively examined the association of polymorphisms in the CYP3A, CYP2J2, CYP2C8, and ABCB1 genes with pharmacokinetic (PKs) and pharmacodynamic (PDs) parameters of tacrolimus in 103 renal transplant recipients for a period of 1 year. CYP3A5 expressers had lower predose concentrations (C0)/dose and higher dose requirements than nonexpressers throughout the study. Among CYP3A5*1 carriers, those also carrying the CYP3A4*1B allele showed the lowest C0/dose, as compared with CYP3A4*1/CYP3A5*3 carriers (54.28 ± 26.45, 59.12 ± 24.00, 62.43 ± 41.12, and 57.01 ± 17.34 vs. 112.37 ± 76.60, 123.21 ± 59.57, 163.34 ± 76.23, and 183.07 ± 107.82 at 1 week, 1 month, 5 months, and 1 year after transplantation). In addition, CYP3A4*1B/CYP3A5*1 carriers showed significantly lower dose‐corrected exposure than CYP3A4*1/CYP3A5*1 carriers 1 year after transplantation (57.01 ± 17.34 vs. 100.09 ± 24.78; P = 0.016). Only the ABCB1 TGC (3435‐2677‐1236) haplotype showed a consistent association with PDs (nephrotoxicity; OR = 4.73; CI: 1.3–16.7; P = 0.02). Our findings indicate that the CYP3A4*1B‐CYP3A5*1 haplotype may have a more profound impact in tacrolimus PKs than the CYP3A5*1 allele. This study does not support a critical role of the CYP450 or ABCB1 single nucleotide polymorphisms in the occurrence of toxicity or acute rejection in renal transplant recipients treated with tacrolimus.

A medical record of diabetes mellitus, polypharmacy and acenocoumarol treatment were risk factors predicting hospital readmission related to ADR.

The objective of this study was to assess the efficacy of contrast-enhanced ultrasonography (CEUS) with SonoVue to evaluate the response to percutaneous treatment (ethanol injection/radiofrequency) of hepatocellular carcinoma in comparison with spiral computed tomography (CT) immediately and 1 month after treatment. Forty-one consecutive cirrhotic patients with early stage tumor (not suitable for resection) were included. Spiral CT and CEUS were performed in all patients before treatment, in the following 24 h, and 1 month later. The results of each examination were compared with the 1-month spiral CT, considered the gold standard technique. The 24-h CEUS and the 24-h spiral CT sensitivity to detect residual disease were 27% and 20%, respectively. The 24-h CEUS and the 24-h spiral CT positive predictive value of persistent vascularization detection were 75% and 66%, respectively. The 1-month CEUS detected partial responses in ten out of 11 cases (91% sensitivity, 97% specificity, 95% accuracy). Spiral CT and CEUS performed in the 24 h following treatment are slightly useful to evaluate therapeutic efficacy. The 1-month CEUS has a high diagnostic accuracy compared with spiral-CT in the usual assessment of percutaneous treatment response.
