目的:描述甲型H1N1流感的临床特征。方法:回顾性分析81例甲型H1N1流感患者的病史、临床表现、实验室辅助检查及临床转归。结果:75.3%的患者为青少年学生,发热(100%)、咳嗽(74.1%)和咽痛(37.0%)是其主要症状。体征可见咽部充血(96.2%)和扁桃体肿大(40.7%)。67.9%的患者表现为外周血中性粒细胞百分比增加,而出现肺部X线异常的比例低(7.4%)。96.3%的患者未经抗病毒治疗临床治愈。结论:此次甲型H1N1流感的临床表现与普通季节性甲型流感类似。对甲型H1N1流感的抗病毒治疗共识值得进一步商榷。
Objective: To describe the clinical characteristics of influenza A (H1N1). Methods: A retrospective analysis of 81 cases of H1N1 influenza patients history, clinical manifestations, laboratory tests and clinical outcomes. Results: 75.3% of the patients were adolescent students. Fever (100%), cough (74.1%) and sore throat (37.0%) were the main symptoms. Signs showed throat congestion (96.2%) and tonsil enlargement (40.7%). 67.9% of patients showed an increase in the percentage of peripheral blood neutrophils, while a low rate of pulmonary X-ray abnormalities (7.4%). 96.3% of patients without clinical cure with antiviral therapy. Conclusion: The clinical manifestations of Influenza A (H1N1) are similar to that of seasonal influenza A (H1N1). The consensus of antiviral treatment of influenza A (H1N1) should be further discussed.
