原因不明发热97例病因分析

目的探讨不明原因长期发热的病因。方法回顾性地分析总结1997年1月至2007年10月间在我院住院且符合不明原因长期发热诊断标准的97例患者的临床资料，对其确诊情况及病因进行分析与比较。结果97例患者经各种检查或试验性治疗最后明确诊断者有82例，确诊率为84．5％。82例确诊的患者病因包括：感染性疾病45例，占46．4％，细菌性感染42例占感染性疾病的93．3％，其中结核病、布氏杆菌病和伤寒／副伤寒各占细菌性感染的21．4％（9／42）、14．3％（6／42）和14．3％（6／42）；结缔组织病16例，占16．5％；肿瘤性疾病13例，占13．4％；其他疾病8例，占8．2％；原因仍未明者15例，占15．5％。结论感染性疾病仍然是不明原因长期发热的主要病因，结核病、布氏杆菌病和伤寒／副伤寒也是感染性疾病中的主要病种；结缔组织病和肿瘤性疾病也占有相当比例；大多数发热通过仔细检查和分析最终可明确诊断。
