--- is the return of a robust immune response resulting from treatment of HIV that may "unmask"
a pre-existing infection; when this occurs, the underlying infection should be treated while
antiretroviral therapy is continued. - CORRECT ANSWER - Immune reconstitution
inflammatory syndrome is the return of a robust immune response resulting from treatment of
HIV that may "unmask" a pre-existing infection; when this occurs, the underlying infection
should be treated while antiretroviral therapy is continued.
The most appropriate management for this patient is to start rifabutin, isoniazid, ethambutol, and
pyrazinamide therapy for tuberculosis. He began antiretroviral therapy 1 month ago and has
responded well, with a significant decrease in viral load and increased CD4 cell count. The
timing of his presentation is consistent with the immune reconstitution inflammatory syndrome
(IRIS) (median 48 days), the return of a robust immune response resulting from treatment of the
HIV that "unmasks" a pre-existing infection that appears like a new acute infection. This
presentation is common with tuberculosis, which may present as a much more acute pulmonary
illness resembling bacterial pneumonia. He had an indeterminate result on interferon-γ release
assay (IGRA) because of an inadequate response to the positive control, which was the result of
immunocompromise at the time of presentation; additionally, the results of IGRA testing are a
