The effectiveness and safety of posaconazole enteric-coated tablet versus oral suspension in invasive fungal infections.

Posaconazole enteric-coated tablet and oral suspension are two oral drugs in the treatment of invasive fungal infections (IFIs). This study compared the effectiveness and safety between posaconazole enteric-coated tablet and oral suspension, and provided a real world basis for the clinical practice. A retrospective cohort study was performed on IFIs patients treated with posaconazole enteric-coated tablet or oral suspension.

Individualized regimen of Posaconazole oral suspension in Chinese HSCT patients based on population pharmacokinetic model.

To establish a population pharmacokinetic (PopPK) model of posaconazole suspension in Chinese hematopoietic stem cell transplantation (HSCT) patients and to recommend an optimal dosing regimen. A single-center, retrospective, model-based study was conducted in 62 Chinese patients, including 103 with posaconazole plasma concentrations. PopPK analysis using NONMEM software.

MiR-204/-211 double knockout exacerbates rheumatoid arthritis progression by promoting splenic inflammation.

Objective: Collagen-induced arthritis (CIA) model was induced in C57BL/6 wild-type (wt) and C57BL/6 miR-204/-211 double-knockout (dKO) mice to investigate the role of miR-204/-211 in suppressing splenic inflammation in rheumatoid arthritis (RA).

Methods: Differences of miR-204/-211 and structure-specific recognition protein 1 (SSRP1) in the spleen of DBA/1J wt and CIA mice were detected via PCR and immunohistochemistry. CIA was induced in both C57BL/6 wt and C57BL/6 miR-204/-211 dKO mice, and the onset of CIA and disease severity were statistically analyzed.

Developmental Pharmacogenetics of CYP2D6 in Chinese Children: Loratadine as a Substrate Drug.

The elucidation of CYP2D6 developmental pharmacogenetics in children has improved, however, these findings have been largely limited to studies of Caucasian children. Given the clear differences in CYP2D6 pharmacogenetic profiles in people of different ancestries, there remains an unmet need to better understand the developmental pharmacogenetics in populations of different ancestries. We sought to use loratadine as a substrate drug to evaluate the effects of ontogeny and pharmacogenetics on the developmental pattern of CYP2D6 in Chinese pediatric patients.

Developmental Pharmacogenetics of SLCO2B1 on Montelukast Pharmacokinetics in Chinese Children.

Background: Montelukast, a potent oral selective leukotriene-receptor antagonist, inhibits the action of cysteinyl-leukotriene in patients with asthma. Although pharmacokinetic studies of montelukast have been reported in Caucasian adults and children, and showed large inter-individual variability on pharmacokinetics, none of these studies has been explored in Chinese children. Given the potential inter-ethnic difference, the purpose of the present study was to evaluate the effects of developmental factors and pharmacogenetics of CYP2C8 and SLCO2B1 on montelukast clearance in Chinese pediatric patients.

Body Surface Area-Based Dosing Regimen of Caspofungin in Children: a Population Pharmacokinetics Confirmatory Study.

We evaluated the population pharmacokinetics of caspofungin in children (2 to 12 years of age). The real-world data from 48 children were best fit by a two-compartment model with first-order elimination. Subsequent covariate analysis demonstrated that body surface area had a significant correlation with caspofungin pharmacokinetics, compared to body weight.

Population Pharmacokinetics and Dosing Optimization of Imipenem in Children with Hematological Malignancies.

Imipenem is widely used for the treatment of children with serious infections. Currently, studies on the pharmacokinetics of imipenem in children with hematological malignancies are lacking. Given the significant impact of disease on pharmacokinetics and increased resistance, we aimed to conduct a population pharmacokinetic study of imipenem and optimize the dosage regimens for this vulnerable population.

[Research progress of selective mGluR1 antagonists].

As an important member of metabotropic glutamate receptors (mGluR), metabotropic glutamate receptor 1 (mGluR1) plays an important role in the signal transduction of central nervous system. Selective mGluR1 antagonists can block the signaling pathway activated by mGluR1 and exert a series of physiological actions including analgesia, antianxiety, antidepression, etc. Currently, the discovery and modification of selective mGluR1 antagonists have become a hot research focus.
