BACKGROUND: We report the first series of Mycobacterium abscessus bacteremia after cytokine-induced killer cell therapy for body beautification and health boosting. METHODS: The clinical manifestations, laboratory and radiological investigations, cytokine/chemokine profiles, and outcomes were described and analyzed. RESULTS: Four patients were admitted, and 3 patients had septic shock. Chest radiographs showed pulmonary infiltrates in all patients. Three patients developed peripheral gangrene, and 1 patient required lower limb and finger amputations. Patient 1 also developed disseminated infection including meningitis and urinary tract infection. Postmortem examination of patient 1 showed focal areas of pulmonary hemorrhage and diffuse alveolar damage, splenic infarct, adrenal necrosis, and hemorrhage, and acid-fast bacilli (AFB) were seen in the lung, liver, kidney, and adrenal gland. Patient 2 developed inguinal granulomatous lymphadenitis about 40 days after onset of lower limb gangrene. Wedge-shaped pulmonary infarcts were found in patient 3, and retinitis and subcutaneous lesions developed in patient 4. Patients in septic shock had dysregulated cytokine/chemokine profiles. Patient 4 with relatively milder presentation had increasing levels of interleukin 17 and cytokines in the interferon-γ/interleukin 12 pathway. All survivors required prolonged intravenous antibiotics. Blood cultures grew M. abscessus for all patients, and admission peripheral blood smear revealed AFB for 3 patients. Mycobacterium abscessus was also isolated from respiratory specimens (2 patients), urine (1 patient), and cerebrospinal fluid (1 patient). Time to initial blood culture positivity (patients 1, 2, and 3: ≤52 hours; patient 4: 83 hours) appeared to correlate with disease severity. CONCLUSIONS: Empirical coverage for rapidly growing mycobacteria should be considered in patients with sepsis following cosmetic procedures.
