Case report of a near-fatal case of Mycobacterium massiliense sepsis after de-clotting of an arteriovenous fistula

Abstract

Abstract Background Mycobacterium massiliense is a rapidly growing a non-tuberculous mycobacterium that has been validated as a separate species from the Mycobacterium abscessus group. Only few antibiotics have demonstrated germicidal activity against Mycobacterium massiliense, and some of those include amikacin, clarithromycin, and cefoxitin. Case presentation We present the first reported case of near-fatal septic shock caused by disseminated Mycobacterium massiliense after de-clotting of an infected arteriovenous fistula, in a patient with end-stage renal disease with concomitant human immunodeficiency virus infection. Early recognition of the culprit organism and treatment with a combination therapy of clarithromycin and amikacin led to rapid improvement. Conclusion This unique case can highlight the importance of taking into consideration Mycobacterium massiliense infection as a cause of arteriovenous fistula thrombosis and highlights the risk of disseminated infection leading to life threatening sepsis upon de-clotting of the fistula.
