摘      要：Background： Nontuberculous Mycobacterium （NTM） bloodstream infection （BSI） is relatively rare. We aimed in this study to evaluate the clinical characteristics, laboratory evaluation, and outcomes of patients with NTM BSI. Methods： We retrospectively reviewed the clinical records of inpatients with NTM BSI at our institution between January 2008 and January 2015 and recorded clinical parameters including age, gender, underlying disease, clinical manifestation, organs involved with NTM disease, species of NTM, laboratory data, treatment and outcome of these patients. We also reviewed the reported cases and case series ofNTM BSI by searching PubMed, EMBASE, and Wanfang databases. Data of normal distribution were expressed by mean ~ standard deviation （SD）. Data of nonnormal distribution were expressed by median and interquartile range （IQR）. Results： Among the ten patients with NTM BSI, the median age was 51 years （IQR 29-57 years） and three patients were males. Eight patients were immunocompromised, with underlying diseases including human immunodeficiency virus （HIV） infection （one patient）, rheumatic diseases （two patients）, breast cancer （one patient）, myelodysplastic syndrome （two patients）, and aplastic anemia （two patients）. Other organ（s） involved were lung （two patients）, endocardium （two patients）, brain, spinal cord, and soft tissue （one each patient）. The median lymphocyte was 0.66 x 109/L （IQR 0.24-1 .93 × 10^9/L）. The median cluster of differentiation 4 （CD4） cell count was 179/ mm^3 （IQR 82-19/mm^3）. Five patients died （three with hematological diseases, one with breast cancer, and one with rheumatic disease）, three recovered, and two were lost to follow-up. Conclusions： We reported all cases in our hospital diagnosed with bloodstream NTM infection that was rarely reported. In this group of patients, patients usually had a high fever and could have multiple organ involvements. All patients with poor prognosis had underlying diseases.
