摘　　要：目的探讨腹膜透析患者存在的营养不良、炎症状态、心血管疾病（动脉硬化）综合征（malnutrition-inflammation-atherosclerosis，MIA综合征），与认知功能的关系。方法临床稳定的透析龄大于3月的腹膜透析患者240例，调查其总认知功能和特异认知功能。记录患者一般情况及生化指标，根据是否白蛋白≤35g／L、超敏-C反应蛋≥3mg／L，判断是否存在营养不良、炎症状态，结合有无心血管病，将患者分为3组，即3个因素均无者，为MIA0组；3个因素中具备任何1种者，为MIA1组；3个因素中具备任意2种或2种以上者，为MIA2组。结果①本组患者中营养不良者36例（15．0％），慢性炎症者114例（47．5％），心血管疾病者86例（35．8％）。MIA0，MIA1和MIA2组分别为79例（32．9％）、87例（36．3％）、74例（30．8％）。总认知障碍发生率在3组分别为6例（7．6％）、16例（18．4％）、15例（20．3％）。在修正的简易智力状态检查量表得分（t=3．629，P〈0．001；t=-2．518，P=0．013）、认知障碍（χ2=5．184，P=0．023；χ2=4．197，P=0．040）、执行能力障碍（χ2=14．574，P〈0．001；χ2=6．817，P=0．009）、连线试验B（χ2=9．317，P=0．002；χ2=4．236，P=0．040）方面，MIA2及MIA1组均较MIA0组差；在连线试验A（χ2=7．281，P=0．007；χ2=15．028，P〈0．001）及视觉空间能力得分（t=2．122，P=0．035；t=2．893，P=0．004）方面，MIA2组较MIA1及MIA0组均差；在即刻记忆得分方面，MIA2组较MIA0组差（t=2．071，P=0．040）。结论腹膜透析患者中MIA综合征和认知障碍密切相关，而罹患MIA综合征2种以上危险因素者较合并0～1个危险因素患者认知障碍的发生率更高、程度更重。Objective This study was to explore the association of malnutrition-inflammation- athero- sclerosis syndrome （MIA） with cognitive function in peritoneal dialysis （PD） patients. Methods A total of 240 clinically stable patients who performed PD for at least 3 months were enrolled. The global cognitive function and specific cognitive functions were investigated. Demographic and biochemical data were record- ed. Serum albumin ≤35g/L and high sensitive C-reactive protein ≥3mg/L were used to diagnose malnutrition and inflammation respectively in these patients. MIA0 referred to those without any of the 3 abnormalities, and MIA1 and MIA2 referred to those with one and 2-3 abnormalities respectively. Results The prevalence of malnutrition, inflammation and cardiovascular disease was 15.0% （n=36）, 47.5% （n=114）, and 35.8% （n=86） respectively. The numbers of patients in MIA0, MIA1, and MIA2 group were 79 （32.9%）, 87 （36.3%）, and 74 （30.8%） respectively. The prevalence of global cognitive impairment was 6 （7.6%）, 16 （18.4%）, and 15 （20.3%） in MIA0, MIA1, and MIA2 groups respectively. As compared to MIA0 group, patients in MIA2 and MIA1 groups had significantly lower 3MS scores （t=3.629, P〈0.001; t=-2.518, P=-0.013）, higher prevalence of cognitive impairment （χ2=5.184, P=0.023; χ2=4.197, P=0.040） and executive dysfunction （χ2=14.574, P〈0.001; χ2=6.817, P=0.009）, and longer time on completing trails B （χ2=9.317, P=0.002; χ2=4.236, P=0.040）. The time on completing trails A （χ2=7.281, P=0.007; χ2=15.028, P〈0.001） was longer and the scores of visuospatial skills （t=-2.122, P=-0.035; t=2.893, P=0.004） were lower in MIA2 group than in MIA1 and MIA0 groups. The scores of immediate memory were lower in MIA2 group than in MIA0 group （t=2.071, P=0.040）. Conclusion The MIA syndrome was closely associated with cognitive impairment in PD patients. Patients with two factors of MIA were prone to have severer cognitive impairment than those without M
