摘要
目的了解2010—2014年苏州地区柯萨奇病毒A16(CA16)感染手足口病(HFMD)的流行特点、临床特征,以及寡腺苷酸合成酶1(OAS1)基因多态性与CA16感染HFMD的关系。方法收集2010—2014年确诊CA16感染HFMD患儿临床资料,分析其流行病学特点;选取其中167例患儿与同期166例EV71感染HFMD患儿进行临床特征比较;应用Taq Man探针技术检测167例CA16感染、166例EV71感染HFMD患儿及163例健康儿童的OAS1 rs10774671位点,分析该基因位点多态性与CA16感染HFMD的相关性。结果共收治HFMD患儿9 016例,CA16核酸检测阳性762例,检出率8.45%;CA16感染HFMD夏季最多,<5岁儿童占94.62%。CA16感染与EV71感染患儿比较,发热时间短,口腔疱疹、溃疡及手足臀皮疹明显,神经系统受累较少;血乳酸脱氢酶、C反应蛋白增高,IgM、IgG升高病例较少,淋巴细胞亚群中CD3+、CD3+CD4+、CD3+CD8+、CD3-CD19+的细胞比例改变明显,差异有统计学意义(P<0.05)。CA16感染HFMD患儿OAS1rs10774671基因位点上GG基因型频率明显高于健康对照组(P=0.038);CA16感染HFMD患儿OAS1 rs10774671位点基因型分布与EV71感染患儿比较差异无统计学意义(P>0.05);普通组与重型组CA16感染HFMD患儿OAS1 rs10774671位点基因型分布差异无统计学意义(P=0.475)。结论苏州地区CA16感染HFMD疫情的发生与年龄、季节有关;CA16感染HFMD患儿有不同的临床和实验室特征;OAS1 rs10774671位点GG基因型儿童更易感染CA16。
Objective To explore the epidemiologic and clinical features of hand, foot and mouth disease (HFMD) caused by Coxsackie virus A16 (CA16) in Suzhou from 2010 to 2014, and analyze the relationship between the SNPs of oligoadenylate synthetase 1 (OAS1) and HFMD caused by CA16 infection.MethodsThe clinical data of children diagnosed with HFMD caused by CA16 during 2010 and 2014 were collected. The epidemiological characteristics were analyzed. Among them, 167 cases were selected to make comparison of the clinical features with 166 cases of HFMD caused by EV71 infection in the same period. The genotyping ofOAS1 rs10774671 was detected by TaqMan probe technique in 167 cases of CA16 infection children, 166 cases of EV71 infection children with HFMD and 163 healthy children. The relationship between polymorphism of gene and infection of CA 16 was analyzed.ResultsA total of 9 016 children with HFMD were included. CA16 nucleic acid detected to be positive in 762 cases. The detection rate was 8.45%. CA16 infection was most commonly in summer. Children under 5 years old accounted for 94.62% infected. Compared with EV71 infected children, CA16 infected children had shorter fever time, severer oral herpes, ulcer, and rash in hand, foot and hip, lesser nervous system involvement, fewer cases of high lactate dehydrogenase, high C reactive protein, high IgM or IgG, and signiifcant changes in the percentage of CD3+, CD3+CD4+, CD3+CD8+ and CD3-CD19+ (P all?<?0.05). The frequency of GG genotype was significantly higher in CA16 infected HFMD children inOAS1 rs10774671 compared with healthy children (P=?0.475). There was no difference in the genotype OAS1 distribution of rs10774571 between common and severe CA16 infected HFMD group (P=?0.475).ConclusionThe epidemiology of CA16 infected HFMD disease in Suzhou area was related with age and season. CA16 infected HFMD children have different clinical features and laboratory characteristics.. Children withOAS1 rs10774671 GG genotype were more susceptible to CA16.
