How do I manage disseminated Mycobacterium avium complex disease in people with HIV?

Background

Advanced HIV disease (AHD) is increasing, with late presentation accounting for half of newly diagnosed people with HIV (PWH) in Europe. Mortality in late-presenting PWH remains high, and Mycobacterium avium complex (MAC) disease, among other opportunistic infections, presents several diagnostic and treatment challenges that lead, ultimately, to a poor clinical outcome.

Objectives

We aimed to provide guidance on the diagnosis and treatment of disseminated MAC disease (dMACd) in PWH.

Sources

We performed a review of original articles, meta-analyses, and systematic reviews retrieved from PubMed.

Content

We reviewed and discussed the most challenging steps in the management of PWH with AHD and dMACd: the current epidemiology in the era of effective antiretroviral treatment; clinical presentation and interpretation of symptoms in the context of other opportunistic infections and immune reconstitution; diagnosis, sampling, and timing to reach a definitive diagnosis; prophylaxis, treatment options, and indications for discontinuing MAC treatment; future perspectives; and the role of rifamycins in the treatment of dMACd.

Implications

Despite the widespread availability of effective antiretroviral treatment, dMACd still represents a major cause of morbidity and mortality in PWH with AHD. Residual challenges are mainly related to the difficulties and timing required to reach a definitive diagnosis, and the discussion regarding the role of rifamycins in the treatment of dMACd is still open.
