摘要:

目的 明确法维拉韦治疗发热伴血小板减少综合征(severe fever with thrombocytopenia syndrome, SFTS)患者的临床疗效和不良反应。方法 2023年3月—2024年8月收集收治于安徽医科大学第一附属医院感染科和重症监护室的SFTS实验室确诊病例的临床资料,根据住院期间是否接受过法维拉韦治疗,将患者分为法维拉韦治疗组(治疗组)和无法维拉韦治疗组(对照组)。使用倾向得分匹配法(propensity score matching, PSM)对两组除“是否接受法维拉韦治疗”外的其他因素按1∶1进行整群匹配,对匹配成功后两组患者的28天生存率和死亡患者的平均生存期进行对比分析,并使用Cox回归模型分析28天生存期的影响因素。结果 共收集272例实验室确诊病例,其中治疗组111例,对照组161例。所有病例中,死亡65例,病死率为23.90%。将年龄、C反应蛋白、D-二聚体、纤维蛋白降解产物、大别班达病毒核酸载量共5个指标认定为PSM的协变量。匹配后,两组均有108例患者纳入研究。匹配后治疗组和对照组的28天生存率分别为85.19%(92/108)和78.70%(85/108),经Log-rank检验,差异无统计学意义(χ2=1.900,P>0.05)。治疗组和对照组28天死亡患者数分别为16例和23例,平均生存期分别为6.5(3.0,9.0)d和2.0(1.0,5.0)d,差异有统计学意义(Z=2.824,P<0.01)。Cox回归分析结果表明,使用法维拉韦是患者生存的保护因素[HR=0.534,95%CI:(0.267,1.068)],年龄增大[HR=1.044,95%CI:(1.004,1.085)]、血清淀粉酶升高[HR=1.003,95%CI:(1.001,1.005)]、使用糖皮质激素[HR=2.243,95%CI:(1.093,4.602)]以及出现意识障碍[HR=11.548,95%CI:(4.786,27.861)]是患者生存的危险因素。服用法维拉韦的111例患者总体耐受性尚可,不良反应较少。结论 法维拉韦治疗SFTS可以延长患者生存期,不良反应少,是一种有效的抗病毒疗法。

Abstract:

Objective To clarify the clinical efficacy and adverse reactions of faveravir in the treatment of patients with severe fever with thrombocytopenia syndrome (SFTS). Methods The clinical data were collected from March 2023 to August 2024 in SFTS cases confirmed by laboratory studies and treated in the Department of Infectious Diseases and the Intensive Care Unit of the First Affiliated Hospital of Anhui Medical University. The cases were divided into faveravir treatment group (treatment group) and non-faveravir treatment group (control group) based on whether they received faveravir medication during their hospitalization. The propensity score matching method (PSM) was used to conduct cluster matching of other factors except whether-they-received-faveravir-treatment between the two groups at a ratio of 1∶1. Comparative analysis was performed on the 28-day survival rate of the two groups after successful matching and the average survival time of deceased patients. Then the influencing factors of the 28-day survival period were analyzed using Cox regression. Results Among the 272 laboratory-confirmed cases collected, 111 were in the treatment group and 161 were in the control group. Of these cases, there were 65 deaths, with a case fatality rate of 23.90%. Five indicators, including the age, C-reaction protein (CRP), D-dimer, fibrin degradation products (FDP), and the nucleic acid load of Bandavirus dabieense, were identified as covariates for PSM. After matching, 108 patients from each group were included in the study. The 28-day survival rates of the treatment group and the control group after matching were 85.19% (92/108) and 78.70% (85/108), respectively. Log-rank test revealed no significant difference (χ2=1.900, P>0.05). There were 16 and 23 deaths respectively in the treatment group and control group, and the average survival time was 6.5 (3.0,9.0) and 2.0 (1.0, 5.0) days. The difference was statistically significant (Z=2.824, P<0.01). The results of Cox regression analysis indicated that the use of faveravir was a protective factor for patient survival [HR=0.534, 95%CI: (0.267, 1.068)], while increased age [HR=1.044, 95%CI: (1.004, 1.085)], elevated serum amylase [HR=1.003, 95%CI: (1.001, 1.005)], the use of glucocorticoids [HR=2.243, 95%CI: (1.093, 4.602)], and the presence of consciousness disturbance were risk factors for patient survival [HR=11.548, 95%CI: (4.786, 27.861)]. The tolerance was overall acceptable in the 111 patients who received faveravir, and the adverse reactions were relatively fewer. Cvonclusion Faveravir for the treatment of SFTS can prolong the survival period of patients and has few adverse reactions, which is an effective antiviral therapy.
