摘要：Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease with high case fatality rate (CFR). Alcohol consumption which impairs host immunity and contributes to tissue damage in a variety of organs may be a predisposing factor of fatal outcome in SFTS. We aimed to determine the role of alcohol consumption on the fatal outcome of SFTS. Patients with laboratory-diagnosed SFTS who were admitted to the Jinan Infectious Disease Hospital, Jinan, China, between January 2011 and November 2018 were evaluated. Demographic, clinical, and laboratory data were recorded. Alcohol consumption was evaluated. The association between a fatal outcome and each demographic, clinical, and laboratory variable with alcohol consumption was assessed. A total of 694 patients with SFTS were identified during the study period. The overall CFR was 20.9 % (95 % CI: 17.9 %–23.9 %). The CFR in non/light drinkers (0−98 g/week) and moderate/heavy drinkers (>98 g/week) was 18.3 % and 35.6 %, respectively (P < 0.001). In age>60 years patients, the overall CFR in moderate/heavy drinker groups were as high as 53.4 % (95 % CI:40.2 %–66.7 %). Comparing to the age≤60y and non/light drinkers, age>60y and moderate/heavy drinkers was associated with increased risk of death with an odds ratio (95 % CI) of 9.9 (5.1–19.1). The interaction between age>60 and alcohol consumption was a significant determinant for death in both genders (F=10.18, P = 0.001). The clinical manifestation, laboratory parameters, and organ injury were significantly extensive and severe in moderate and heavy drinkers. In conclusion, hazardous alcohol consumption and aging synergistically increase the risk of death in patients with SFTS. In SFTS endemic areas, it is important for older individuals to minimize the exposure risks and abstain from alcohol. © 2020 Elsevier GmbH
