[Consensus of Chinese experts on clinical application of lactoferrin].

Lactoferrin is a natural protein with various physiological activities, which has the function of regulating immunity, anti-microbial, regulating iron absorption, promoting the proliferation of intestinal cells, and multiple pathophysiological processes. In recent years, lactoferrin has been widely used in infants, pregnant women, and the elderly. In order to more comprehensively understand the clinical application of lactoferrin and establish the method and index system of lactoferrin application in different populations, clinical nutritionists, together with experts from multiple disciplines, used the evidence grading method of GRADE Collaboration Network Ⅱ under the principle of evidence-based medicine to search for clinical evidence and repeatedly discuss. The experts group reached a consensus on the effect of lactoferrin reducing the risk of infection in premature infants, the incidence of respiratory and gastrointestinal diseases in infants, improving the anemia status of infants and pregnant women, improving the eradication rate of Helicobacter pylori in children and adults, and improving the immune function of the elderly, which could be used as a reference for medical professionals in clinical work.乳铁蛋白是一种具有多种生理活性的天然蛋白质，参与调节免疫功能、抗微生物、调节铁吸收、促进肠道细胞增殖分化等多种病理生理过程。近年来，乳铁蛋白在婴幼儿、孕妇及老年等人群中广泛应用。为更全面地了解乳铁蛋白的临床应用，建立不同人群乳铁蛋白的应用指征、方法和评价体系，由临床营养专家协同多个学科专家在循证医学的原则下采用GRADE协作网Ⅱ的证据分级方法，搜寻临床证据并反复讨论，就乳铁蛋白可降低早产儿感染风险、婴幼儿呼吸道和胃肠道疾病发生率、改善婴幼儿和孕妇的贫血状态、提高儿童及成人幽门螺杆菌根治率及改善老年人免疫功能等方面达成共识，供广大医务人员在临床工作中参考应用。.
