    Abstract: Interindividual variations in the efficacy of antiseizure medications make epilepsy treatment challenging. This is due to genetic factors such as gene polymorphisms in Adenosine-triphosphate (ATP)-binding cassette sub-family B member 1 ( ABCB1 ). In this article, the impact of polymorphisms in the P-glycoprotein-encoding gene, ABCB1 (C1236T, G2677T/A, and C3435T), on levetiracetam disposition was evaluated in Uygur Chinese children with epilepsy. Methods: MDR1 C3435T polymorphism was analyzed by polymerase chain reaction–fluorescence staining in situ hybridization. The χ 2 test and Fisher exact test were used to analyze the allelic and genotypic distribution of ABCB1 , C1236T, G2677T, and C3435T between the drug-resistant and drug-responsive groups. Differences in steady-state and dose-corrected levetiracetam serum concentrations between the different genotypes were analyzed using 1-way analysis of variance and Mann–Whitney test. Results: Total 245 Uygur children with epilepsy were analyzed [drug-resistant, n = 117 (males:females = 53:64) and drug-responsive, n = 128 (males:females = 76:52)] . The frequency of ABCB1 C1236T, G2677T/A, and ABCB1 C3435T genotypes, alleles, haplotypes, or diplotypes did not differ significantly between the 2 groups ( P 〉 0.05). Significantly higher levetiracetam concentrations and serum concentration/body mass dose were seen in ABCB1 2677-GT, TT, GA, and AT genotypes and 3435-TT carriers compared with GG and CC carriers ( P = 0.021 and P = 0.002 versus P = 0.001 and P = 0.000, respectively). Conclusions: ABCB1 G2677T/A and C3435T may affect levetiracetam disposition and therapeutic efficacy in Uygur children with epilepsy. Genetic analysis could be a valuable tool for predicting the response to antiseizure medications before the start of treatment and could contribute to personalized medicine for Uygur children with epilepsy.

    Abstract: Information on the efficacy and plasma concentration of perampanel (PER) in Chinese pediatric patients with epilepsy is limited. Therefore, this real-world retrospective study aimed to assess the efficacy, tolerability, and plasma concentration of the maximum dose of PER for epilepsy treatment in Chinese pediatric patients. Methods: A total of 107 pediatric patients from 2 hospitals in China were enrolled in this study. The plasma concentration of PER was determined using ultrahigh-performance liquid chromatography. The primary efficacy endpoint was the seizure reduction rate after PER treatment at the last follow-up. Results: The response rate to PER therapy was 59.8% (64/107). The authors observed that patients younger than 6 years of age (n = 49) showed a significantly lower concentration-to-dose ratio than patients with ages between 6 and 14 years (n = 58) (2.2 ± 1.7 vs. 3.0 ± 1.8 mcg·mL −1 ·kg·mg −1 , respectively; P 〈 0.05). Patients who received enzyme-inducing antiseizure medication had significantly lower concentration-to-dose ratios than those who did not receive enzyme-inducing antiseizure medication (EIASM) (2.1 ± 1.8 vs. 3.1 ± 2.0 mcg·mL −1 ·kg·mg −1 , P 〈 0.05). A total of 37 patients (34.6%) reported treatment adverse events. Patients with somnolence and irritability had a significantly higher PER plasma concentration than the “no treatment-emergent adverse effect” groups ( P 〈 0.05). Conclusions: PER is an effective and well-tolerated treatment option for patients with epilepsy. To ensure the clinical efficacy and safety of PER in pediatric patients, it is necessary to monitor its plasma concentrations.

    Abstract: P-glycoprotein plays a role in drug resistance of epileptic patients by limiting gastrointestinal absorption and brain access to antiseizure medications. This study aimed to evaluate the association between ABCB1 polymorphisms and drug resistance in epileptic pediatric patients. Methods Three hundred seventy-seven epileptic pediatric patients were treated with antiseizure medications and subsequently divided into the drug-responsive group (n = 256, 68%) and drug-resistant group (n = 121, 32%). The genomic DNA of patients in the different groups was extracted, followed by the determination of the ABCB1 gene polymorphisms using polymerase chain reaction–fluorescence staining in situ hybridization. Results Drug-resistant patients significantly exhibited a combined generalized and focal onset than drug-responsive patients (χ 2 = 12.278, P 〈 0.001). The TT (χ 2 = 5.776, P = 0.016) genotypes of G2677T and CT (χ 2 = 6.165, P = 0.013) and TT (χ 2 = 11.121, P = 0.001) genotypes of C3435T were significantly more frequent in drug-resistant patients than drug-responsive patients. Similarly, the GT-CT diplotype was significantly more frequent in drug-resistant patients than in drug-responsive patients. Conclusion Our study findings suggest that the ABCB1 G2677T and C3435T polymorphisms are significantly associated with drug resistance in epileptic patients.

    Abstract: We aimed to evaluate the effect of the ABCC2 1249G 〉 A (rs2273697) and −24C 〉 T (rs717620) polymorphisms on lacosamide (LCM) plasma concentrations and the efficacy of LCM in Uygur pediatric patients with epilepsy. Methods: We analyzed 231 pediatric patients with epilepsy, among which 166 were considered to be LCM responsive. For drug assays, 2–3 mL of venous blood was collected from each patient just before the morning LCM dose was administered (approximately 12 hours after the evening dose, steady-state LCM concentrations). The remaining samples after routine therapeutic drug monitoring were used for genotyping analysis. The χ 2 test and Fisher exact test were utilized for comparative analysis of the allelic and genotypic distribution of ABCC2 polymorphisms between the LCM-resistant and LCM-responsive groups. The Student t test or Mann–Whitney U test was conducted to analyze differences in plasma LCM concentration among pediatric patients with epilepsy with different genotypes. Results: Patients with the ABCC2 1249G 〉 A GA genotype (0.7 ± 0.3 mcg/mL per kg/mg) and AA genotype (0.5 ± 0.3 mcg/mL per kg/mg) showed significantly ( P 〈 0.001) lower LCM concentration-to-dose (CD) ratios than patients with the GG genotype (1.0 ± 0.4 mcg/mL per kg/mg). Moreover, patients with the ABCC2 −24C 〉 T CT genotype (0.6 ± 0.2 mcg/mL per kg/mg) and TT genotype (0.6 ± 0.3 mcg/mL per kg/mg) presented a significantly ( P 〈 0.001) lower LCM CD ratio than patients with the CC genotype (1.1 ± 0.4 mcg/mL per kg/mg). Conclusions: The ABCC2 1249G 〉 A (rs2273697) and ABCC2 −24C 〉 T (rs717620) polymorphisms can affect plasma LCM concentrations and treatment efficacy among a population of Uygur pediatric patients with epilepsy, causing these patients to become resistant to LCM. In clinical practice, ABCC2 polymorphisms should be identified before LCM treatment, and then, the dosage should be adjusted for pediatric patients with epilepsy accordingly.

    Abstract: P-glycoprotein, encoded by ABCB1 (or MDR1 ), may contribute to drug resistance in epilepsy by limiting gastrointestinal absorption and brain access to antiseizure medications. The study aimed to evaluate the impact of ABCB1 polymorphisms on lacosamide (LCM) serum concentrations in Uygur pediatric patients with epilepsy. Methods: The serum concentrations of LCM were determined by ultrahigh performance liquid chromatography, and the ABCB1 polymorphism was analyzed through polymerase chain reaction–fluorescence staining in situ hybridization. The χ 2 test and the Fisher exact test were used to analyze the allelic and genotypic distributions of ABCB1 polymorphisms between the drug-resistant and drug-responsive patient groups. Differences in steady-state and dose-corrected LCM serum concentrations between different genotypes were analyzed using the one-way analysis of variance and the Mann–Whitney test. Results: A total of 131 Uygur children with epilepsy were analyzed, and of them, 41 demonstrated drug resistance. The frequency of the GT genotype of ABCB1 G2677T/A was significantly higher in the drug-resistant group than that in the drug-responsive group ( P 〈 0.05, OR = 1.966, 95% CI, 1.060–3.647). Patients with the G2677T/A-AT genotype had a statistically significantly lower concentration-to-dose (CD) value than patients with the G2677T/A-GG genotype (mean: 0.6 ± 0.2 versus 0.8 ± 0.5 mcg/mL per mg/kg, P 〈 0.001). Significantly lower LCM serum concentrations were observed in ABCB1 C3435T CT and TT genotype carriers than those in the CC carriers ( P = 0.008 and P = 0.002), and a significantly lower LCM CD value was observed in ABCB1 C3435T CT genotype carriers than that in the CC carriers ( P = 0.042). Conclusions: ABCB1 G2677T/A and C3435T polymorphisms may affect LCM serum concentrations and treatment efficacy in Uygur pediatric patients with epilepsy, leading to drug resistance in pediatric patients.

    Abstract: Aortic dissection (AD) is a fatal cardiovascular disorder without effective medications due to unclear pathogenic mechanisms. Bestrophin3 (Best3), the predominant isoform of bestrophin family in vessels, has emerged as critical for vascular pathological processes. However, the contribution of Best3 to vascular diseases remains elusive. METHODS: Smooth muscle cell–specific and endothelial cell–specific Best3 knockout mice (Best3 SMKO and Best3 ECKO , respectively) were engineered to investigate the role of Best3 in vascular pathophysiology. Functional studies, single-cell RNA sequencing, proteomics analysis, and coimmunoprecipitation coupled with mass spectrometry were performed to evaluate the function of Best3 in vessels. RESULTS: Best3 expression in aortas of human AD samples and mouse AD models was decreased. Best3 SMKO but not Best3 ECKO mice spontaneously developed AD with age, and the incidence reached 48% at 72 weeks of age. Reanalysis of single-cell transcriptome data revealed that reduction of fibromyocytes, a fibroblast-like smooth muscle cell cluster, was a typical feature of human ascending AD and aneurysm. Consistently, Best3 deficiency in smooth muscle cells decreased the number of fibromyocytes. Mechanistically, Best3 interacted with both MEKK2 and MEKK3, and this interaction inhibited phosphorylation of MEKK2 at serine153 and MEKK3 at serine61. Best3 deficiency induced phosphorylation-dependent inhibition of ubiquitination and protein turnover of MEKK2/3, thereby activating the downstream mitogen-activated protein kinase signaling cascade. Furthermore, restoration of Best3 or inhibition of MEKK2/3 prevented AD progression in angiotensin II–infused Best3 SMKO and ApoE −/− mice. CONCLUSIONS: These findings unveil a critical role of Best3 in regulating smooth muscle cell phenotypic switch and aortic structural integrity through controlling MEKK2/3 degradation. Best3–MEKK2/3 signaling represents a novel therapeutic target for AD.

    Abstract: Psoriasis and vitiligo are common immune-related skin disorders. Patients are often clinically diagnosed with both diseases. However, whether psoriasis and vitiligo share common genetic factors and aberrant signal pathways that predispose patients to both diseases remains unclear. This study was performed to clarify these factors using bioinformatics analysis. Methods: Publicly available gene expression profiles for GSE109248 and GSE53552 in psoriasis and GSE75819 and GSE65127 in vitiligo from lesional and non-lesional skin tissues were downloaded from the Gene Expression Omnibus database and analyzed to identify differentially expressed genes (DEGs). Gene Ontology terms analysis, Kyoto Encyclopedia of Genes and Genomes enrichment analysis, and protein–protein interaction analysis was also performed to elucidate the molecular mechanisms. Results: Nine overlapping DEGs were found between psoriasis and vitiligo. They are AKR1B10, CRABP1, FOXC1, GPM6B, KIT, MLPH, SOX10, TAGLN, and TUBB2B, respectively. Except for the upregulation of AKR1B10 , others are downregulated. Pathway enrichment analyses revealed that these overlapping DEGs were mainly enriched in melanocyte differentiation; exocrine system development; mesenchymal cell development; stem cell differentiation and development; and neural crest cell differentiation, development, and migration. RT-qPCR was used to verify the expression of the DEGs in lesions compared to adjacent non-lesional tissues from three patients with psoriasis combined with vitiligo. Research confirmed that there were statistically significant differences among AKR1B10, FOXC1, KIT, MLPH and SOX10 in lesions compared to adjacent non-lesional tissues ( P 〈 0.05), which was consistent with the bioinformatical results. Conclusion: In this study, we detected potential genes and their associated enriched pathways to help understand the molecular mechanisms underlying the simultaneous occurrence of psoriasis and vitiligo.

    Abstract: A meta-analysis. Objective: To update the current knowledge about the association between overweight, obesity, and low back pain (LBP) risk, we conducted a meta-analysis of published cohort studies. Summary of Background Data: The association between obesity and LBP risk has been the research focus in the past decade. However, available data from studies on the association between obesity and LBP remains debatable. Methods: An extensive English language literature retrieval regarding the association between overweight, obesity, and the risk of LBP incidence was conducted on PubMed and EMBASE databases through December 2015. Meta-analysis for all the included literature was performed by STATA 12.0 to summarize test performance with Forest plots after a heterogeneity test. Moreover, subgroup and sensitivity analyses were performed to examine the potential candidate-effect factors. Results: A total of 10 cohort studies including 29,748 subjects satisfied the predefined eligibility criteria. The pooled odds ratio (OR) for overweight and obesity compared with normal weight was 1.15 [95% confidence interval (CI), 1.08–1.21) and 1.36 (95% CI, 1.18–1.57), respectively. Moreover, subgroup analysis proved that increased body mass index was associated with an increased incidence of LBP in both men (overweight: pooled OR=1.16, 95% CI, 1.04–1.31; obesity: pooled OR=1.36, 95% CI, 1.15–1.61) and women (overweight: pooled OR=1.24, 95% CI, 1.04–1.50; obesity: pooled OR=1.40, 95% CI, 1.08–1.82). There was no evidence of publication bias. Conclusions: Our findings consistently show that overweight and obesity are risk factors for LBP in men and women. Maintaining a healthy body weight may be one of the factors preventing the occurrence of LBP. Level of Evidence: Level 1.

    Abstract: Serum alanine aminotransferase (ALT) is a biomarker of hepatocyte damage. However, the relationship between normal range of serum ALT level and metabolic syndrome (MetS) has not been completely understood. This study aimed to investigate the correlation between normal range of serum ALT level and MetS. A total of 2453 participants from the Beijing Community Pre-Diabetes study were enrolled. Multiple linear regression analysis was performed to calculate the regression coefficient. Normal serum ALT levels were divided into quartiles. Logistic regression model was used to compare the relative risk of MetS, and the receiver operating characteristic (ROC) curve to calculate the optimal ALT boundary value for predicting MetS. The frequency of MetS increased with the ALT level within the normal range. Compared with the first group, the risk of MetS was greater in the other quartiles of ALT level in males, the difference was significant for the fourth group. For females, the risk of MetS increased with ALT level within the normal range as well, with all differences showing statistical significance. The optimal ALT boundary value of the ROC curve for males and females was 24.5 and 14.5 U/L, respectively. ALT was related to metabolic factors and used as one of the indicators to assess the morbidity risk of metabolic diseases.
