摘  要:目的探讨发热伴血小板减少综合征(SFTS)患者临床特征及死亡相关的危险因素。方法动态观察40例SFTS患者的临床特点和实验室指标,比较存活组(33例)和死亡组(7例)患者的白细胞计数、血小板计数、ALT、AST、CK、乳酸脱氢酶(LDH)、PT、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)在病程各时间点的水平。正态分布的计量资料采用t检验,非正态分布的计量资料采用非参数检验,计数资料采用χ^2检验,死亡危险因素采用单一变量分析。结果死亡组和存活组患者APTT在病程第1~7天分别为56.40s和44.45s(Z=5.419,P=O.040),病程第8~10天分别为66.25s和36.85S(Z=10.112,P=0.009),病程第11~13天分别为(125.06±11.88)S和(33.44±6.50)S(t=45.760,P〈0.01)。病程第11~13天,死亡组与存活组患者的ALT分别为(783.00±210.12)U/L和(137.33±89.59)U/L(t=7.989,P=0.016),AST分别为890U/L和99u/L(Z=60.248,P〈0.01),CK分别为2315u/L和314U/L(Z=122.065,P〈0.01),LDH分别为1075U/L和509U/L(Z=44.642,P〈0.01),PT分别为16S和11S(Z=7.917,P=0.031),TT分别为120S和20S(Z=1361.674,P〈0.01)。病程第11~13天是疾病进展的关键时期,患者的神志改变(OR=6.60,95%CI:2.94~14.80)、出血(OR=9.29,95%CI:1.48~58.47)、PT〉15s(OR=24.00,95%CI:1.99~289.60)、APTT〉70s(OR=42.67,95%CI:3.54~514.85)、TT〉120s(OR=0.14,95%CI:0.02~0.88)是死亡相关的危险因素(均P〈0.05)。结论SFTS发病早期APTT、TT及PT升高且随病程进展呈进行性延长提示预后不佳。Objective To summarize the clinical and laboratory characteristics of patients with severe fever with thrombocytopenia syndrome (SFTS) and to identify the related risk factors for mortality. Methods Clinical features and laboratory parameters were collected from 40 SFTS patients (7 deaths and 33 survivors). Dynamic changes of laboratory data were compared between the two groups, including white blood cell count (WBC), platelet count (PLT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT). Continuous variables with normal distribution were compared with t test, and those with non-normal distribution were compared with nonparametric test; categorical variables were compared with χ^2 test. Univariate Logistic regression was used to evaluate the risk factors associated with death. Results For the deceased patients and the survivors, the APTT were 56.40 s and 44.45 s, respectively (Z=5. 419, P=0.04) at day 1-7. Those were 66.25 s and 36.85 s, respectively (Z=10. 112, P=0. 009) at day 8--10, and (125.06±11.88) s and (33. 442=6.50) s, respectively (t=45. 760, P〈0.01) at day 11--13. At day 11--13, the ALT levels in deceased patients and survivors were (783.00±210.12) U/L and (137.33±89.59) U/L, respectively (t=7. 989, P=0. 016), AST levels were 890 U/L and 99 U/L, respectively (Z=60. 248, P d0.01), CK levels were 2 315 U/L and 314 U/L, respectively (Z= 122. 065, P〈0.01), LDH levels were 1 075 U/L and 509 U/L, respevtively (Z=44. 642, P〈0.01), PT were 16 s and 11 s, respectively (Z= 7. 917, P=0. 031), and TT were 120 s and 20 s, respectively (Z= 1 361. 674, P〈0. 01). Day 11--13 after the onset of illness was the critical stage for SFTS. Consciousness alteration (OR = 6.60,95 % CI: 2.94--14.80), bleeding (0R=9.29,95%CI:1. 48--58. 47), PT〉15 s (O
