Interstitial cystitis (IC) is a progressive bladder disease characterized by increased urothelial permeability, inflammation of the bladder with abdominal pain. While there is no consensus on the etiology of the disease, it was believed that restoring the barrier between urinary solutes and (GAG) urothelium would interrupt the progression of this disease. Currently, several treatment options include intravesical delivery of hyaluronic acid (HA) and/or chondroitin sulfate solutions, through a catheter to restore the urothelial barrier, but have shown limited success in preclinical, clinical trials. Herein we report for the first time successful engineering and characterization of biphasic system developed by combining cross‐linked hyaluronic acid and naïve HA solution to decrease inflammation and permeability in an in vitro model of interstitial cystitis. The cross‐linking of HA was performed by 4‐arm‐polyethyeleneamine chemistry. The HA formulations were tested for their viscoelastic properties and the effects on cell metabolism, inflammatory markers, and permeability. Our study demonstrates the therapeutic effects of different ratios of the biphasic system and reports their ability to increase the barrier effect by decreasing the permeability and alteration of cell metabolism with respect to relative controls. Restoring the barrier by using biphasic system of HA therapy may be a promising approach to IC.

一种高分子量透明质酸双相分散体作为间质性膀胱炎的潜在治疗剂

间质性膀胱炎 (IC) 是一种进行性膀胱疾病,其特征是尿路上皮通透性增加、膀胱发炎并伴有腹痛。虽然对该疾病的病因尚未达成共识,但人们认为恢复尿溶质和 (GAG) 尿路上皮之间的屏障将中断该疾病的进展。目前,几种治疗选择包括通过导管膀胱内输送透明质酸 (HA) 和/或硫酸软骨素溶液以恢复尿路上皮屏障,但在临床前、临床试验中的成功率有限。在此,我们首次报告了通过结合交联透明质酸和初始 HA 溶液开发的双相系统的成功工程和表征,以减少间质性膀胱炎体外模型中的炎症和通透性。HA的交联是通过4臂-聚乙烯胺化学进行的。测试了 HA 制剂的粘弹性和对细胞代谢、炎症标志物和渗透性的影响。我们的研究证明了双相系统不同比例的治疗效果,并报告了它们通过相对于相对对照降低细胞代谢的渗透性和改变来增加屏障效应的能力。通过使用 HA 治疗的双相系统恢复屏障可能是一种有前途的 IC 方法。HA的交联是通过4臂-聚乙烯胺化学进行的。测试了 HA 制剂的粘弹性和对细胞代谢、炎症标志物和渗透性的影响。我们的研究证明了双相系统不同比例的治疗效果,并报告了它们通过相对于相对对照降低细胞代谢的渗透性和改变来增加屏障效应的能力。通过使用 HA 治疗的双相系统恢复屏障可能是一种有前途的 IC 方法。HA的交联是通过4臂-聚乙烯胺化学进行的。测试了 HA 制剂的粘弹性和对细胞代谢、炎症标志物和渗透性的影响。我们的研究证明了双相系统不同比例的治疗效果,并报告了它们通过相对于相对对照降低细胞代谢的渗透性和改变来增加屏障效应的能力。通过使用 HA 治疗的双相系统恢复屏障可能是一种有前途的 IC 方法。我们的研究证明了双相系统不同比例的治疗效果,并报告了它们通过相对于相对对照降低细胞代谢的渗透性和改变来增加屏障效应的能力。通过使用 HA 治疗的双相系统恢复屏障可能是一种有前途的 IC 方法。我们的研究证明了双相系统不同比例的治疗效果,并报告了它们通过相对于相对对照降低细胞代谢的渗透性和改变来增加屏障效应的能力。通过使用 HA 治疗的双相系统恢复屏障可能是一种有前途的 IC 方法。
