1、麻疹发病特征论文【摘要目的探究再次麻疹的发病特征和免疫学机制。方法对连续诊治的36例再次麻疹患者做流行病学及免疫情况调查,分析其临床特征。据临床表现分典型(TY)、轻型典型(MT)及轻型非典型(MAT)3型。用ELISA法检测患者急性期及25名有麻疹病史的麻疹密切接触者血清抗-麻疹病毒(MV)IgM、IgG和抗-风疹病毒IgM。结果36例再次麻疹患者年龄12.5~27(16.1)岁,以13~16岁为多,占61.1%;其第一次患麻疹年龄1岁以内者27例(75.0%),而25名健康者中仅2例在1岁以内,差异有显著性(P%26lt;
2、0.01)。性别间无明显差别。36例中MT18例(50.0%),MAT18例(50.0%),无TY麻疹,首诊均误诊。抗-MVIgM均阳性,抗-风疹病毒IgM均阴性。抗-MVIgG滴度在1摘要:200,1摘要:300,1摘要:400和1摘要:600阳性者分别为7,14,12和3例,其中抗-MVIgG水平≤1摘要:300患者69.6%为MT麻疹;≥1摘要:400阳性者83.3%为MAT。抗-MVIgG水平和病情呈显著负相关(P%26lt;0.05)。25名有麻疹病史者抗-MVIgG≤1摘要:400阳性者9例(36.0%),显著低于
3、患者组(94.4%)(P%26lt;0.01)。结论(1)1周岁内患麻疹者13年后抗体衰减至可再患麻疹。(2)再次麻疹患者因临床表现不典型及有麻疹病史而极易误诊,需检测抗-MVIgM阳性方可诊断。(3)发病及病情轻重主要取决于体内抗-MVIgG水平。【麻疹;临床表现;免疫Clinicalmanifestationsandimmunologicalmechanisminpatientswithsecondmeasles【AbstractObjectiveTostudytheclinicalmanifestationsandimm
