Immune reconstitution inflammatory syndrome (IRIS) is a state of hyperinflammatory response that usually occurs in the first six months of treatment of HIV/AIDS patients. It is a potential complication of the use of highly active antiretroviral therapy (HAART).

How do you prevent immune reconstitution?

How can immune reconstitution inflammatory syndrome be prevented? The most effective prevention of IRIS would involve initiation of ART before the development of advanced immunosuppression. IRIS is uncommon in individuals who initiate antiretroviral treatment with a CD4+ T-cell count greater than 100 cells/uL.

What is reconstitution inflammatory syndrome?

INTRODUCTION. The term “immune reconstitution inflammatory syndrome” (IRIS) describes a collection of inflammatory disorders associated with paradoxical worsening of preexisting infectious processes following the initiation of antiretroviral therapy (ART) in HIV-infected individuals [1-6].

What is TB IRIS?

Tuberculosis-immune reconstitution inflammatory syndrome (TB-IRIS) is an abnormal, excessive immune response against alive or dead Mycobacteria tuberculosis that may occur in either HIV-infected or, more rarely, uninfected patients.

What are the symptoms of IRIS?

IRIS generally occurs within the first 8 weeks of ART initiation with relatively nonspecific symptoms of fevers, night sweats, nausea, fatigue, and jaundice.

The term “immune reconstitution inflammatory syndrome” (IRIS) describes a collection of inflammatory disorders associated with paradoxical worsening of preexisting infectious processes following the initiation of antiretroviral therapy (ART) in HIV-infected individuals [1-6].

How is IRIS diagnosed?

Because of wide variation in clinical presentation and the still increasing spectrum of symptoms and etiologies reported, diagnosis remains problematic. Furthermore, no test is currently available to establish an IRIS diagnosis. Diagnosis of IRIS requires a high index of suspicion.
