摘要:目的  探討发热伴血小板减少综合征(SFTS)的临床表现和影像学特点。方法  选择2015年7月~2019年8月我院90例确诊为SFTS患者的临床及影像学资料,根据预后分为预后良好组(74例)和预后不良组(16例),比较两组临床表现及实验室指标,采用Logistic回归分析SFTS预后不良的危险因素,总结SFTS的影像学特征。结果  预后不良组消化道出血及中枢神经系统症状发生多于预后良好组,差异有统计学意义(P<0.05);两组血小板、D-二聚体、乳酸脱氢酶、肌酸激酶同工酶、谷草转氨酶、尿酸及血肌酐水平比较,差异有统计学意义(P<0.05);Logistic回归分析显示,中枢神经系统症状是影响SFTS患者预后的危险因素(OR=7.708,95%CI:1.692~35.114);85例患者胸部CT平扫表现包括双肺索条(49.41%),胸腔积液(51.76%),腋窝淋巴结肿大(18.82%);78例患者腹部CT表现包括胰周渗出(3.85%),腹腔积液(11.54%);31例盆腔CT扫描显示腹股沟淋巴结肿大(70.97%)。结论  发热伴血小板减少综合征实验室指标水平过高可能提示预后不良,中枢神经系统症状是SFTS预后不良的独立危险因素,其影像表现双肺伴或不伴渗出性病变,胸腔积液,浅表淋巴结肿大。

Abstract:Objective  To explore the clinical manifestations and imaging features of fever with thrombocytopenia syndrome (SFTS).Methods  The clinical and imaging data of 90 patients diagnosed with SFTS in our hospital from July 2015 to August 2019 were selected and divided into good prognosis group (74 cases) and poor prognosis group (16 cases) according to prognosis. Performance and laboratory indicators, using Logistic regression to analyze the risk factors of poor prognosis of SFTS, summarize the imaging characteristics of SFTS.Results  Gastrointestinal bleeding and central nervous system symptoms occurred in the poor prognosis group more than the good prognosis group, the difference was statistically significant (P<0.05); platelets, D-dimer, lactate dehydrogenase, creatine kinase isoenzymes in the two groups,Aspartate aminotransferase, uric acid and blood creatinine levels were compared, the difference was statistically significant (P<0.05); Logistic regression analysis showed that the central nervous system symptoms are risk factors affecting the prognosis of SFTS patients (OR = 7.708, 95% CI: 1.692~35.114); 85 patients with chest CT plain scan including double lung cord (49.41%), pleural effusion (51.76%), axillary lymphadenopathy (18.82%); 78 patients with abdominal CT manifestation including peripancreatic exudation (3.85%), peritoneal effusion (11.54%); 31 cases of pelvic CT scan showed inguinal lymphadenopathy (70.97%). Conclusion  Fever with excessively high laboratory index levels of thrombocytopenia syndrome may indicate a poor prognosis. Central nervous system symptoms are independent risk factors for poor prognosis of SFTS. The imaging findings show double lungs with or without exudative lesions, pleural effusion, and shallow enlarged lymph nodes.

发热伴血小板减少综合征(fever with thrombocytopenia syndrome,SFTS)是由发热伴血小板减少综合征病毒感染引起的新发传染病[1-3]。临床表现包括发热、胃肠道症状和体征,白细胞、血小板计数减少,重症患者可有出血症状、中枢神经系统症状、多器官功能衰竭[4]。目前对SFTS的影像学报道较少,本研究通过回顾性分析2015年7月~2019年8月我院90例SFTS患者的临床和影像学特征,旨在提高临床医生对本病的认识,报道如下。

1资料与方法

1.1一般资料  回顾性分析2015年7月~2019年8月安徽医科大学第二附属医院90例确诊为SFTS患者的临床及影像学资料,所有患者血清标本显示新型布尼亚病毒核酸阳性和/或特异性抗体阳性,最终经治疗后好转74例、未愈12例、死亡4例。根据预后分为预后良好组(74例)和预后不良组(16例),预后良好组男性37例,女性37例,年龄52~70岁,平均年龄(61.74±9.94)岁;预后不良组男性6例,女性10例,年龄56~77岁,平均年龄(66.81±10.70)岁。

1.2方法  收集90例患者的临床症状及实验室指标,比较两组患者的临床表现、实验室指标及影像学表现,进行单因素与多因素回归分析。……
