目的 研究轮状病毒肠炎并发肠道外损伤的发生情况及影响因素,监测轮状病毒肠炎患儿免疫球蛋白和淋巴细胞亚群变化,了解轮状病毒肠炎患儿发病时免疫状态.方法 研究对象为2007年1月至2008年12月在我院住院确诊的轮状病毒肠炎患儿(观察组)64例,对照组为同期在发育儿科体检正常者18例.记录患儿临床表现的同时,采用ELISA方法检测粪便轮状病毒特异性抗原,流式细胞术进行淋巴细胞亚群分析,透色比浊法测定血清IgG、IgA、IgM,生化法检测肝功能和心肌酶谱.结果轮状病毒感染可导致肝脏、心肌、呼吸及神经系统等多脏器损害.观察组患儿丙氨酸氨基转移酶(ALT)、天冬氨酸转移酶(AST)、肌酸激酶(CK)、肌酸激酶同工酶(CK-mB)活性均明显高于对照组(P<0.05);<1岁组患儿肝功能损伤发生率显著高于>1岁组(P<0.05);重型腹泻组患儿CK[(324.5±995.5)U/dl]、CK-mB[(93.8±61.5)U/dl]活性明显高于轻型者[CK(252.8±130.4)U/dl,CK-mB(59.6+32.6)U/dl],差异有显著性(P<0.05).观察组免疫球蛋白IgG[(4.46±1.56)g/L]明显低于对照组[(5.80±1.67)g/L],差异有显著性(P<0.05);淋巴细胞亚群中观察组CD4+[(29.0±4.18)%]较对照组[(38.6±3.97)%]降低,CDl9+检测结果[(38.8±3.94)%]较对照组[(23.1±7.70)%]升高,差异均有显著性(P<0.05);观察组患儿CD4+/CD8+比例倒置.结论 轮状病毒肠炎患儿可出现肠道外感染表现,以呼吸系统、肝脏、心肌及中枢神经系统受累居多;轮状病毒感染可导致体液及细胞免疫功能低下.肝功能、心肌酶谱、免疫球蛋白及淋巴细胞亚群测定对监测患儿病情变化及指导治疗有重要的临床意义. 相似文献

Objective To evaluate the parenteral complications and their risk factors and to study the immune status by detecting immunoglobulin and lymphocyte subsets in children with rotavirus enteritis. Methods Sixty-four children with rotavirus enteritis who were treated in Shengjing Hospital of China Medical University between January 2007 and December 2008(observation group) and 18 healthy chiIdren for health screening at pediatric health care center (normal control group) were reeruimd.Clinical manifestations were collected,stool specimens were detected for rotavirus using ELISA,lymphocyte subsets were detected using flow cytometer,and immunoglobulin.liver enzyme and myocardial enzyme were detected.Results Rotavirus enteritis may be complicated by parenteral complications(liver,myocardium,respiratory and nervous system).The activity of ALT,AST,LDH,CK and CK-mB were higher in observation group than that in normal control group(P<0.05).In observation group,liver injury rate in children younger than 12 months was higher than that in children older than 12 months,and the activity of CK and CK-mB were highcr in severe diarrhea cases[CK(324.5±995.5)U/dl,CK-mB(93.8 4±61.5)U/dl]than that in mild diarrhea cases [CK(252.8±130.4)U/dl,CK.mB(59.6±32.6)U/dl](P<0.05).The level of IgG was lower in observation group[(4.46±1.56)g/L]than that in control group[(5.80±1.67)g/L](P<0.05).Lymphocytes subsets study revealed that the activity of CD4+ in observation group[(29.0±4.18)%]was lower than that in control group[(38.6±3.97)%](P<0.05),the activity of CDl9+ [(38.8±3.94)%]was higher than that in control group[(23.1±7.70)%](P<0.05)and the CD4+/CD8+ ratio was reverse in observafion group.Conclusion Rotavirus enteritis may be complicated by parenteral injuries which get liver,myocardium,respiratory and nervous system involved.Children with rotavirus enteritis Call lead to low immune function.Determination of liver enzyme,myocardial enzyme,immunoglobulin and lymphocyte subsets has important clinical significance to monitoring the change of condition and guiding treatment. 相似文献

婴幼儿轮状病毒性肠炎140例发病特点分析 总被引:22,自引:0,他引:22
目的 了解2002—2003年肠道门诊轮状病毒性肠炎的发病特点。方法 对2002年1月~2003年12月在肠道门诊就诊的急性腹泻患儿粪便标本进行常规检查、大便潜血检查、轮状病毒检测和细菌培养,并对1岁以下的患儿进行喂养情况的调查。结果 轮状病毒性肠炎2002年感染率为21.74%,2003年感染率为27.11%,2a总感染率为24.91%,2岁以内婴幼儿发病率高,10~12月份为发病高峰,同时合并条件致病菌生长率为23.88%;1岁以内婴儿腹泻程度母乳喂养组与人工喂养组之间比较差异有统计学意义。结论 轮状病毒仍是秋冬季婴幼儿急性腹泻的主要病原之一,母乳喂养婴儿轮状病毒肠炎腹泻的程度相对较轻;轮状病毒腹泻时存在菌群紊乱,应以调节肠道菌群和对症处理为主要治疗手段,避免滥用抗生素。 相似文献

轮状病毒肠道外感染发病机制的研究进展 总被引:1,自引:0,他引:1
轮状病毒是一种双链RNA病毒,其基因序列已经基本查明.它是引起婴幼儿严重腹泻最常见的病原体,不仅可以引起胃肠道疾病,还可导致全身各个脏器的病变,发病机制和多个因素有关.肠道外发病可能是免疫功能异常(或正常)的情况下,轮状病毒穿透胃肠道屏障通过血液播散,感染肠道外多个器官所致. 相似文献

To identify the risks and predictors for extraintestinal Salmonella infection (ETI) in infants and children with nontyphoidal Salmonella enteritis, we performed a retrospective review of 326 infants and children with diarrhea and rectal swab cultures positive for nontyphoidal Salmonella enteritis seen at Ramathibodi Hospital between 1981 and 1983. Nineteen patients had bacteremia. The overall rate of bacteremia was 5.8% which was 24.3% of those having blood cultures taken. Salmonella typhimurium was the most common cause of ETI and the most invasive among the common serotypes causing enteritis. The clinical characteristics of the patients with high probabilities of having ETI were: younger than 6 months of age; high body temperature; and immunocompromising conditions. The observed frequency of ETI in these patients was 21.9 to 26.3% compared with 0 to 0.7% in patients without those risk factors. 相似文献
