儿童蛋白丢失性肠病(PLE)可由许多不同的胃肠疾病所引起;蛋白丢失可能是暂时的,如急性肠炎时,或者是持续性的如肠道淋巴管扩张时。粘膜渗透性的改变或淋巴流淤滞导致蛋白大量地丢失而进入肠腔,随后便发生了低白蛋白血症和外周性水肿。Hill 最近报告3例儿童暂时性PLE伴急性胃炎,经鉴定胃粘膜上有幽门弯曲杆菌。这些儿童在腹泻后有眶周水肿,骶部和腿部有凹性水肿,一例有腹水,均有低蛋白血症和低白蛋白血症。通过收集4天的大便 Childhood protein-losing enteropathy (PLE) can be caused by a number of different gastrointestinal disorders; protein loss may be temporary, such as acute enteritis, or persistent, such as gut dilatation. Changes in mucosal permeability or stasis of lymphatic flow cause the protein to be lost in large quantities into the intestine, followed by hypoalbuminemia and peripheral edema. Hill recently reported 3 children with transient PLE with acute gastritis and identified H. pylori on gastric mucosa. These children have periorbital edema after diarrhea, concave edema of the sacral and leg, one case of ascites, both hypoproteinemia and hypoalbuminemia. By collecting 4 days of stool
