Objective: To analyzed the clinical characteristics and prognosis of patients with H7N9 avian influenza. Methods: The baseline characteristics, clinical manifestations, treatments, laboratory and imaging findings were collected and analyzed for 20 patients with H7N9 avian influenza admitted to the First Affiliated Hospital of Nanchang University from December 2016 to March 2017. According to the final clinical outcome, the patients were divided into the death group and the survival group. Ten patients in the death group died, and 10 patients in the survival group were discharged. The data with normal distribution were analyzed by t test. The data with non-normal distribution were analyzed by Wilcoxon rank sum test. Results: Of the 20 patients, 13 were males and 7 were females, aging 40-82 years, with a mean age of (60±12) years. Twelve patients had a definite history of poultry exposure and 10 had chronic underlying diseases such as hypertension and diabetes. The clinical manifestations were mainly fever, cough, hemoptysis, respiratory distress, fatigue, etc. In the survival group, the platelet count was(167-315)×10(9)/L, while it was (78-152)×10(9)/L in the death group. The average white blood cell count was (7.78-11.52)×10(9)/L and (9.91-15.93)×10(9)/L in the survival and death groups respectively. The average value of lymphocyte count was (0.69-1.59)×10(9)/L and (0.58-0.86)×10(9)/L in the survival and death groups respectively. In the death group the glutamic-pyruvic transaminase (ALT) value was (14.0-352.0) U/L, the total bilirubin value was (6.9-34.5) μmol/L, the creatine kinase MB (CK-MB) was (16.0-162.0) U/L, the serum calcium value was (1.4-2.0) mmol/L, the C-reactive protein value was (33.1-414.0) mg/L, and the calcium reduction prime value was (0.6-100.0) μg/L. In the survival group,the ALT value was (25.0-181.0) U/L, the total bilirubin value was (4.8-25.9) μmol/L, the CK-MB value was (15.0-40.0) U/L, the serum calcium value was (1.9-2.4) mmol/L, the C-reaction protein value was (12.8-52.5) mg/L, and the procalcitonin value was (0.3-23.3) μg/L. Sixteen cases suffered severe pneumonia. Twelve patients received extracorporeal membrane oxygenation (ECMO), and 4 survived. The cause of death was mainly related to factors such as age, chronic underlying diseases and severity of illness. Conclusions: Human infection with H7N9 avian influenza virus was highly pathogenic, and prone to progress into severe pneumonia, with a high mortality. Decreased platelet count was associated with mortality ( t= 4.07, P= 0.001), predictive of patient outcome.
