Sci Rep:反复膀胱注射富血小板血浆可改善难治性间质性膀胱炎患者的症状和改变泌尿功能蛋白

2020-10-04 AlexYang MedSci原创

反复膀胱注射自体富含血小板的血浆(PRP)可以改善间质性膀胱炎/膀胱疼痛综合征(IC/BPS)患者的症状;然而,该疗法有效性的客观证据依旧缺乏。

反复膀胱注射自体富含血小板的血浆(PRP)可以改善间质性膀胱炎/膀胱疼痛综合征(IC/BPS)患者的症状;然而,该疗法有效性的客观证据依旧缺乏。

最近,有研究人员调查了PRP治疗后泌尿标志物的变化。40名常规治疗难治的IC/BPS患者,每月4次注射PRP;使用10 mL PRP溶液,血小板浓度为外周血血小板浓度的2.5倍。研究人员在在基线和第4次PRP注射时评估了13种功能蛋白、生长因子和细胞因子的尿液水平。临床参数包括视觉模拟量表(VAS)疼痛评分、每日尿频、夜尿发作、功能性膀胱容量和整体反应评估(GRA)。研究发现,治疗后GRA和症状评分显著下降。在GRA≥2的患者中,在第1个月和3个月的第四次PRP注射后成功率分别为70.6%和76.7%。VAS疼痛评分、频率、夜尿次数均有明显下降(P<0.05)。治疗后尿中神经生长因子、基质金属蛋白酶-13、血管内皮生长因子水平均显著下降(分别为p=0.043、p=0.02、p=0.000);而第4次PRP治疗时血小板衍生生长因子-AB较基线显著增加(p=0.004)。

PRP给药后泌尿标记的变化和与临床改善的相关性

最后,研究人员指出,反复膀胱注射PRP能显著改善IC/BPS患者的症状,并伴随着相关生物标志物水平的变化。
