Sarcoidosis in a patient with AIDS: A manifestation of immune restoration syndrome

Sarcoidosis has been rarely reported in the presence of HN infection. Helper T-lymphocyte depletion may attenuate granuloma formation. We present a patient who developed active sarcoidosis after being started on highly active antiretroviral therapy (HAART), which increased his CD4 count and decreased his viral load. There have been reports of exaggerated responses to mycobacteria and viruses with the restoration of T-cell function after HAART in HIV-infected patients. We propose that active sarcoidosis seen in this patient is also a manifestation of this newly observed "immune restoration disease.".
