Integrating metabolomics and lipidomics revealed a decrease in plasma fatty acids but an increase in triglycerides in children with drug-refractory epilepsy.

Objective: The drug-refractory epilepsy (DRE) in children is commonly observed but the underlying mechanisms remain elusive. We examined whether fatty acids (FAs) and lipids are potentially associated with the pharmacoresistance to valproic acid (VPA) therapy.

Methods: This single-center, retrospective cohort study was conducted using data from pediatric patients collected between May 2019 and December 2019 at the Children's Hospital of Nanjing Medical University.

Association between serum vitamin D status and the anti-seizure treatment in Chinese children with epilepsy.

Objective: To compare the serum 25-OH-VitD levels, the major marker of vitamin D (VitD) status, between healthy children and children with epilepsy before initiation of and during anti-seizure medications (ASMs) treatment and to evaluate the potential influence factors on 25-OH-VitD levels. Another major aim was to assess the potential role of VitD supplementation.

Methods: For comparison, we finally enrolled and collected data from 6,338 healthy children presenting to Health Care Department and 648 children visiting primary care pediatricians with symptoms of epilepsy in Children's Hospital of Nanjing Medical University from January 2019 to June 2021.

An LC-ESI-MS/MS assay for the therapeutic drug monitoring of 15 antiseizure medications in plasma of children with epilepsy.

Oral antiseizure medications are the preferred option for the clinical treatment of epilepsy. Therapeutic drug monitoring has become an important means of achieving individualized treatment of epilepsy. A sensitive, accurate and rapid LC-ESI-MS/MS method was developed and validated for the simultaneous determination of 15 antiseizure medications in human plasma (carbamazepine, gabapentin, pregabalin, phenytoin, zonisamide, oxcarbazepine, tiagabine, lamotrigine, topiramate, phenobarbital, lacosamide, primidone, 10,11-Dihydro-10-hydroxy carbamazepine, ethosuximide, and levetiracetam).

Effect of long-term valproic acid therapy on lipid profiles in paediatric patients with epilepsy: a meta-analysis.

Objective: Despite the potential role of valproic acid (VPA) in weight gain, the effects of VPA therapy on lipid profiles remain unclear. This study aimed to review the influence of VPA therapy on serum lipid profiles in children with epilepsy.

Methods: This meta-analysis was conducted on data from PubMed, Web of Science, Cochrane Library, and Embase databases.

Switching Between LC-ESI-MS/MS and EMIT Methods for Routine TDM of Valproic Acid in Pediatric Patients With Epilepsy: What Clinicians and Researchers Need to Know.

Valproic acid (VPA) is a widely used antiseizure medication and its dosing needs to be tailored individually through therapeutic drug monitoring (TDM) to avoid or prevent toxicity. Currently, immune-enzymatic assays such as Enzyme Multiplied Immunoassay Technique (EMIT), and Liquid Chromatography (LC)-based techniques, particularly coupled to Electrospray Ionization Tandem Mass Spectrometry (LC-ESI-MS/MS), resulting a potential lack of concordance between laboratories. In this study, plasma VPA concentrations were determined for 711 pediatric patients with epilepsy by a routine EMIT assay and by a validated in-house LC-ESI-MS/MS method on the same group of samples, aimed to address the aforementioned concern.

Genetic and Non-genetic Factors Contributing to the Significant Variation in the Plasma Trough Concentration-to-Dose Ratio of Valproic Acid in Children With Epilepsy.

This study was conducted to evaluate the potential genetic and non-genetic factors contributing to plasma trough concentration-to-dose ( /) ratio of valproic acid (VPA) in pediatric patients with epilepsy. A single-center, retrospective cohort study was performed by collecting data from 194 children aged 1-14 years between May 2018 and November 2018. The oral solution ( = 135) group and the sustained-release (SR) tablet group ( = 59) were defined, and the plasma VPA was measured.

Therapy for Apnoea of Prematurity: A Retrospective Study on Effects of Standard Dose and Genetic Variability on Clinical Response to Caffeine Citrate in Chinese Preterm Infants.

Introduction: Apnoea of prematurity (AOP) is among the most common diagnoses in the neonatal intensive care unit. Caffeine treatment is a preferred treatment choice. However, neonatal caffeine therapy results in significant intersubject variability.

Steroid-resistant Nephrotic Syndrome in Children: A Mini-review on Genetic Mechanisms, Predictive Biomarkers and Pharmacotherapy Strategies.

Steroid-resistant nephrotic syndrome (SRNS) constitutes the second most frequent cause of chronic kidney disease in childhood. The etiology of SRNS remains largely unknown and no standardized treatment exists. Recent advances in genomics have helped to build understanding of the molecular mechanisms and pathogenesis of the disease.

The role of Chinese clinical pharmacists in parenteral nutrition for children using the Screening Tool Risk on Nutrititional Status and Growth (STRONGkids).

Background The abuse and deficiency of nutritional support coexist in China, and clinical pharmacists have responsibilities to promote the rational use of drugs. Objective Apply the Screening Tool Risk on Nutritional Status and Growth to observe the influence of parenteral nutrition on children with an incarcerated hernia and educate physicians to promote the rational use of parenteral nutrition. Setting Department of General Surgery of Nanjing children's hospital.

Valproic Acid and the Liver Injury in Patients with Epilepsy: An Update.

Background: Valproic acid (VPA) as a widely used primary medication in the treatment of epilepsy is associated with reversible or irreversible hepatotoxicity. Long-term VPA therapy is also related to increased risk for the development of non-alcoholic fatty liver disease (NAFLD). In this review, metabolic elimination pathways of VPA in the liver and underlying mechanisms of VPA-induced hepatotoxicity are discussed.

Alterations of drug-metabolizing enzymes and transporters under diabetic conditions: what is the potential clinical significance?

There will be 642 million people worldwide by 2040 suffering from diabetes mellitus. Long-term multidrug therapy aims to achieve normal glycemia and minimize complications, and avoid severe hypoglycemic events. The appreciation of the drug-metabolizing enzymes and drug transporters as critical players in the treatment of diabetes has attracted much attention regarding their potential alterations in the pathogenesis of the disease.

Potential Pharmacokinetic Herb-Drug Interactions: Have we Overlooked the Importance of Human Carboxylesterases 1 and 2?

Background: Herbal products have grown steadily across the globe and have increasingly been incorporated into western medicine for healthcare aims, thereby causing potential pharmacokinetic Herb-drug Interactions (HDIs) through the inhibition or induction of drug-metabolizing enzymes and transporters. Human Carboxylesterases 1 (CES1) and 2 (CES2) metabolize endogenous and exogenous chemicals including many important therapeutic medications. The growing number of CES substrate drugs also underscores the importance of the enzymes.

The Adverse Effect of the 2-1-1 Regimen for Rabies PEP in Preschool Children.

Post-exposure prophylaxis (PEP) has proved to be the most important measure for rabies prevention and control. There is little information regarding adverse reactions to the Essen and 2-1-1 regimens in preschool children (aged 0-6). We reexamined the outcomes of 1,109 preschool children who were vaccinated using SPEEDA under the Essen regimen between January 2011 and December 2012 and 1,267 preschool children under the 2-1-1 regimen between January 2013 and December 2014.
