A retrospective cohort study was conducted using a large health insurance data set. Patients
with one or more claims with asthma diagnosis, two or more prescriptions for FSC (250/50- or 100/50-mg formulations) or FP (220- or 110-mg formulations), and one or more asthma exacerbations or five or more short-acting beta agonist (SABA) prescriptions within 1 year before initial receipt of study medications were included. Health-care utilization/costs and controller therapy compliance were compared for patients receiving FSC versus FP using multivariate regression analysis controlling for FP dose and baseline characteristics. A total of 7779 patients met inclusion criteria (5769, FSC, and 2010, FP) with comparable mean follow-up (FSC, LY2835219 chemical structure 685 days; FP, 670 days; p = 0.151). Controlling for FP dosage and baseline characteristics, FSC patients had lower PD-1/PD-L1 Inhibitor 3 cost risks of asthma-related exacerbations, fewer SABAs and systemic corticosteroids, higher costs of asthma medications and total asthma-related health care, and lower total asthma-related health-care costs excluding study medication cost. In asthma patients with recent exacerbation or frequent SABA use, receipt of FSC reduced asthma-related exacerbation risks and rescue
medication use versus receipt of FP.”
“Context: Sotos syndrome is a rare genetic disorder with a distinct phenotypic spectrum Bafilomycin A1 Transmembrane Transporters inhibitor including overgrowth and learning difficulties. Here we describe a new case of Sotos syndrome with a 5q35 microdeletion, affecting the fibroblast growth factor receptor 4 (FGFR4) gene, presenting with
infantile hypercalcemia. Objective: We strove to elucidate the evanescent nature of the observed hypercalcemia by studying the ontogenesis of FGFR3 and FGFR4, which are both associated with fibroblast growth factor (FGF) 23-mediated mineral homeostasis, in the developing human kidney. Design: Quantitative RT-PCR and immunohistochemical analyses were used on archival human kidney samples to investigate the expression of the FGFR signaling pathway during renal development. Results: We demonstrated that renal gene and protein expression of both FGFRs increased during fetal development between the gestational ages (GAs) of 14-40 weeks. Yet FGFR4 expression increased more rapidly as compared with FGFR3 (slope 0.047 vs 0.0075, P = .0018). Moreover, gene and protein expression of the essential FGFR coreceptor, Klotho, also increased with a significant positive correlation between FGFR and Klotho mRNA expression during renal development. Interestingly, we found that perinatal FGFR4 expression (GA 38-40 wk) was 7-fold higher as compared with FGFR3 (P = .0035), whereas in adult kidney tissues, FGFR4 gene expression level was more than 2-fold lower compared with FGFR3 (P = .
