Congenital anomalies of the kidney and urinary tract (CAKUT) are defined as structural malformations of the kidney and/or urinary tract. Heat shock proteins (HSPs) are expressed in the kidney in response to cellular changes, such as thermal, hemodynamic, osmotic, inflammatory, and mechanical stresses. This study aimed to assess uHSP70 levels during acute urinary tract infections (UTI) and non-infection periods in patients with CAKUT, and to evaluate whether uHSP70 is elevated in CAKUT subtypes.
Among patients with CAKUT, 89 patients with UTI (CAKUT-A), 111 without UTI (CAKUT-B), and 74 healthy children were included in the study. uHSP70 levels were measured using enzyme-linked immunosorbent assay (ELISA).
uHSP70 level was significantly higher in the CAKUT-A group than in the CAKUT-B and healthy control groups (p < 0.0001). Moreover, the level of uHSP70 was significantly higher in the CAKUT-B group than in the control group (p < 0.0001), but was not different between the CAKUT subtypes (p > 0.05).
Urine HSP70 can also be used to predict UTI in patients with CAKUT. Moreover, uHSP70 levels were higher in children with CAKUT during the non-infectious period than in healthy controls. This suggests that children with CAKUT are at risk of chronic non-infectious damage.
先天性肾脏和尿路畸形（CAKUT）被定义为肾脏和/或尿路的结构畸形。热休克蛋白（HSPs）在肾脏中表达以应对细胞变化，如热、血流动力学、渗透压、炎症和机械应激。本研究旨在评估CAKUT患者急性尿路感染（UTI）期间和非感染期的尿HSP70水平，并评估CAKUT各亚型中尿HSP70是否升高。
在CAKUT患者中，89例UTI患者（CAKUT - A组）、111例无UTI患者（CAKUT - B组）和74例健康儿童纳入研究。采用酶联免疫吸附测定（ELISA）测量尿HSP70水平。
CAKUT - A组的尿HSP70水平显著高于CAKUT - B组和健康对照组（p < 0.0001）。此外，CAKUT - B组的尿HSP70水平显著高于对照组（p < 0.0001），但CAKUT各亚型之间无差异（p > 0.05）。
尿HSP70也可用于预测CAKUT患者的UTI。此外，CAKUT患儿在非感染期的尿HSP70水平高于健康对照组。这表明CAKUT患儿存在慢性非感染性损伤的风险。
