Simultaneous Diagnosis of Pneumococcal Sepsis and Disseminated Mycobacterium avium Complex Infection in a Patient with Acquired Immunodeficiency Syndrome / 대한내과학회지

ABSTRACT

The incidence of bacteremia in human immunodeficiency virus (HIV)-infected patients is significantly decreased by highly active antiretroviral therapy (HAART). However, bacteremia remains a major cause of morbidity and mortality in HIV-infected patients. A 43-year-old male who had fever and cough for 1 week presented to the emergency room. He was diagnosed with acquired immunodeficiency syndrome combined with atypical pneumonia and started on antibiotics plus HAART. After 3 days, Streptococcus pneumoniae was grown in blood cultures. Three weeks later, acid-fast bacilli cultures of blood and bronchoalveolar lavage fluid grew Mycobacterium avium complex (MAC); hence, the patient was treated with antimycobacterial drugs. HIV-infected patients with persistent fever despite administration of appropriate antibiotics should be examined for simultaneous infection by other organisms, such as nontuberculous mycobacteria. We report a case of simultaneous detection of MAC and S. pneumoniae in the blood of a treatment-naïve HIV-infected patient.
