Substantial Morbidity

Coccidioidomycosis causes substantial morbidity and mortality in endemic areas, and dissemination is frequent in patients with impaired cellular immunity such as AIDS. Immune reconstitution inflammatory syndrome (IRIS) is paradoxical clinical worsening after initiation of antiretroviral therapy (ART) in a patient with HIV and a simultaneous opportunistic infection (OI). Immune reconstitution inflammatory syndrome has been well described for a host of mycobacterial, viral, and fungal OIs and malignancies such as Kaposi sarcoma. To date, only 3 cases of IRIS due to coccidioidomycosis have been reported in the literature. At our institution, we report 4 cases of IRIS in HIV-infected patients with disseminated coccidioidomycosis. Unfortunately, all 4 patients died of worsening coccidioidal infection after initiating ART. The optimal timing of ART in patients with AIDS and coccidioidomycosis remains to be elucidated.

Clinical Worsening

One of the purposes of antiretroviral therapy (ART) is to restore the immune system. However, it can sometimes lead to an aberrant inflammatory response and paradoxical clinical worsening known as the immune reconstitution inflammatory syndrome (IRIS). We describe a 23-year-old male, HIV1 infected with a rapid progression phenotype, who started ART with TCD4+ of 53 cells/mm3 (3,3%) and HIV RNA = 890000 copies/mL (6 log). Four weeks later he was admitted to the intensive care unit with severe sepsis. The diagnostic pathway identified progressive multifocal leukoencephalopathy, digestive Kaposi sarcoma, and P. aeruginosa bacteraemia. Five weeks after starting ART, TCD4+ cell count was 259 cells/mm3 (15%) and HIV RNA = 3500 copies/mL (4 log). He developed respiratory failure and progressed to septic shock and death. Those complications might justify the outcome but its autopsy opened Pandora’s box: cerebral and cardiac toxoplasmosis was identified, as well as hemophagocytic syndrome, systemic candidiasis, and Mycobacterium avium complex infection. IRIS remains a concern and eventually a barrier to ART. Male gender, young age, low TCD4 cell count, and high viral load are risk factors. The high prevalence of subclinical opportunistic diseases highlights the need for new strategies to reduce IRIS incidence.

Inflammatory Syndrome

Immune reconstitution inflammatory syndrome (IRIS) is a phenomenon observed in patients recovering from immunodeficiency. The clinical presentation of IRIS involves the unmasking of covert infections or the worsening of overt conditions. Several causes and pathways have been suggested, most recognizing an inflammatory flare component occurring in the context of rapid immune reconstitution. In HIV-infected patients, IRIS inadvertently occurs as the consequence of successful antiretroviral therapy, and it is affiliated with improvement of the immune function, complicating the course of the disease and presenting treatment challenges to clinicians. The pathogenesis of IRIS is poorly understood, but in recovering HIV patients, its initiation and progression seem to be primarily linked to an increase in CD4+ T-helper and CD8+ T-suppressor cell count and a reduction in T-regulatory cells, all endorsed by exaggerated cytokine release and activity. The clinical presentation of IRIS is usually atypical. The manifestations depend on the trigger antigen, which can be an infective agent (viable or nonviable), a host antigen, or a tumor antigen. Most IRIS cases are self-limiting, but a few cases can be overwhelming and life-threatening; hence, early recognition is important. In most cases, there is no need to discontinue the antiretroviral therapy, although in the more severe cases, other clinical intervention may be necessary.

Immune reconstitution inflammatory syndrome (IRIS) in HIV-infected subjects initiating antiretroviral therapy most commonly involves new or worsening manifestations of previously subclinical or overt infectious diseases. Reports of non-infectious IRIS are much less common but represent important diagnostic and treatment challenges. We report on a 34-year-old HIV-infected male patient with no history of gout who developed acute gouty arthritis in a single joint one month after initiating highly active antiretroviral therapy.
