Bacille Calmette-Guerin(BCG)疫苗用來預防肺結核,此疫苗之安全性極高。但是在免疫缺損之病患仍然可能造成嚴重感染。吾人報告一例患有嚴重混合免疫不全疾病之男嬰接種BCG疫苗之後發生播散性感染。皮膚病理切片顯示有許多抗酸性桿菌存在,且PCR分析證實皮膚、腦脊髓液與胃液抽取物之菌種均為Mycobacterium bovis。雖然給予抗結核菌藥物之治療與骨髓移植,病患仍不治死亡。
Bacille Calmette-Guerin(BCG) vaccine is administered to prevent tuberculosis and is considered to have an excellent safety profile. However, severe BCG infection can occur in individuals with defects of the host immune response. We report an eight-month-old male baby suffered from severe combined immunodeficiency with disseminated BCG infection. Skin biopsy showed numerous acid-fast bacilli and PCR analysis of skin, cerebral spinal fluid and gastric aspirate all identified Mycobacterium bovis. Patient died despite anti-TB drugs and bone marrow transplantation.
