Abstract:
Objective To explore the influence of clinical indicators in patients with thrombocytopenia syndrome (SFTS) with severe fever on disease development and prognosis.Methods The SFTS patients who were admitted to the Department of Infection Diseases of Wuhan Union Hospital between April 1, 2015 and October 30, 2015 were included.Among 164 patients with SFTS, there were 136 cases recovered and 28 cases died.Clinical date including clinical manifestations and laboratory test index were collected and retrospectively analyzed.The correlation between the prognosis and clinical indicators were analyzed with the Spearman correlation analysis, the discriminatory power of clinical dates were tested with the area under the receiver-operating characteristic curve.Results The average age of died patients in the study was (64.5±9.1), which increased significantly(t=-3.609,P<0.01) compared with recovered patients with (56.9±10.2).Laboratory results suggest all patients had a drop in white blood cell and platelet count;almost all patients had a drop in serum calcium levels, and a rise in aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine kinase (CK), activated partial thromboplastin time (APTT), D-dimmer levels.The nucleic acid quantification of SFTSV suggests death patients (5.83±0.98) lg TCID50/mL was significantly higher than the recovered patients (3.96±1.08) lg TCID50/mL, with statistical difference (t=-8.49, P<0.01).Conclusions Age, the nucleic acid quantification of SFTSV, CK and APTT are factors can be used to predict prognosis of SFTS.
