The effect of morning versus evening administration of empagliflozin on its pharmacokinetics and pharmacodynamics characteristics in healthy adults: a two-way crossover, non-randomised trial

Background: Empagliflozin is an SGLT2 inhibitor approved for use in patients with diabetes mellitus type 2 (DMT2) with or without other cardiovascular disease. Empagliflozin is taken once daily without rationale on the optimal timing for administration. This study aimed to determine the chronopharmacological effects of morning vs evening administration of empagliflozin (10 mg) in healthy Egyptian adults, by investigating the pharmacokinetics and pharmacodynamics parameters of empagliflozin depending on the intake time. Methods: An open label, sequential, two‐way crossover trial comprised of two periods with a washout period of 7 days. All participants received a single oral dose of empagliflozin (JARDIANCE ®; 10 mg film coated tablet) in the evening, and after a seven-day washout period, the morning. Pharmacokinetics parameters (primary endpoints: tmax (h), Cmax (ng/ml), AUC 0-t (ng.h/ml); secondary endpoints: AUC 0 to ∞(ng.h/ml)) were assessed. Method validation was done prior to injection in LC/MS/MS and samples were processed by Liquid-Liquid extraction. The pharmacodynamic profile (UGE 0-24) was determined after method validation (glucose hexokinase method). Results: Tmax increased by 35% in the evening phase compared to the morning phase, while Cmax decreased by -6.5% in the evening dose compared to the morning dose. Additionally, AUC0 to ∞ increased in the evening phase by 8.25% compared to the morning phase. The mean cumulative amount of glucose excreted (UGE (0-24)) increased by 43% in the evening dose compared to the morning dose Conclusion: Despite the difference in pharmacokinetics parameters between evening and morning doses, Cmax, AUC0-t, AUC 0-∞, didn’t differ on the bioequivalence level. In addition, as UGE (0-24) didn’t statistically differ, thus, we can conclude that there is no statistical significance between the morning and evening doses.

Long Intergenic Non-Coding RNA 00511 (LINC00511) Genetic Variations and Haplotypes in Breast Cancer: A Case-Controlled Study and Bioinformatics Analysis

Long intergenic non-coding RNA 00511 (LINC00511) has been involved in the development of several types of cancer including breast cancer (BC). Several single nucleotide polymorphisms (SNPs) can be found in the genomic regions of long non-coding RNAs (lncRNAs) and are associated with the tumorigenesis of many cancers. The objective of the current study is to assess whether LINC00511 SNPs (rs11657109, rs9906859, rs17780195, rs1558535, and rs4432291) could be related with BC incidence in the Egyptian population. Five SNPs of LINC00511 were analyzed in a case&ndash;control study of 267 BC cases and 150 controls. Logistic regression analysis was used to test the association between LINC00511 SNPs and BC incidence. We found that the TT genotype of rs11657109 significantly increased BC incidence (OR: 2.177, 95%CI: 1.260&ndash;3.763) and this SNP was associated with high incidence of luminal A BC specifically using different genetic models. Haplotype (A09 A91 A35 G95 T59) was strongly associated with an increased BC incidence as it was totally absent in controls. These findings suggest that LINC00511 SNP rs11657109 is associated with BC susceptibility in the Egyptian population

Whole-exome sequencing of T-B+ severe combined immunodeficiency in Egyptian infants, JAK3 predominance and novel variants

Summary Severe combined immunodeficiency (SCID) is fatal if not treated with immune reconstitution. In Egypt, T-B+ SCID accounts for 38·5% of SCID diagnoses. An accurate genetic diagnosis is essential for choosing appropriate treatment modalities and for offering genetic counseling to the patient's family. The objectives of this study were to describe the clinical, immunological and molecular characteristics of a cohort of twenty Egyptian patients with T-B+ SCID. The initial diagnosis (based on clinical features and flow cytometry) was followed by molecular investigation (whole-exome sequencing). All patients had the classic clinical picture for SCID, including failure to thrive (n = 20), oral candidiasis (n = 17), persistent diarrhea (n = 14), pneumonia (n = 13), napkin dermatitis (n = 10), skin rash (n = 7), otitis media (n = 3) and meningitis (n = 2). The onset of manifestations was at the age of 2·4 ± 1·6 months and diagnosis at the age of 6·7 ± ·5 months, giving a diagnostic delay of 4·3 months. JAK3 gene variants were most frequent (n = 12) with three novel variants identified, followed by IL2Rγ variants (n = 6) with two novel variants. IL7Rα and CD3ε variants were found once, with a novel variant each. T-B+NK− SCID accounted for approximately 90% of the Egyptian patients with T-B+SCID. Of these T-B+NK− SCID cases, 60% were autosomal recessive syndromes caused by JAK3 mutations and 30% were X-linked syndromes. It might be useful to sequence the JAK3 gene (i.e. targeted Sanger sequencing) in all T-B+ SCID patients, especially after X-linked SCID has been ruled out. Hence, no more than 10% of T-B+ SCID patients might require next-generation for a molecular diagnosis.</jats:p
