CO-INFECTIONS (C BENSON, SECTION EDITOR) Management of the Immune Reconstitution Inflammatory Syndrome Graeme Meintjes & James Scriven & Suzaan Marais Published online: 3 July 2012 # Springer Science+Business Media, LLC 2012 Abstract The immune reconstitution inflammatory syn- drome (IRIS) is a frequent early complicati on of antiretroviral therapy (ART) in patients with advanced HIV. Because there is no confirmatory diagnostic test, the diagnosis is based on clinical presentation and exclusion of alternative causes for deterioration, such as antimicrobial drug resistance. Opportu- nistic infection treatment should be optimized. Mild cases may require symptomatic therapy alone or nonsteroidal anti- inflammatory drugs. Corticosteroids have been used to treat more severe cases of IRIS associated with mycobacterial and fungal infections. There is evidence from a randomized con- trolled trial that prednisone reduces morbidity and improves symptoms in paradoxical tuberculosis (TB)-IRIS. Neurologi- cal TB-IRIS is potentially life-threatening; high-dose cortico- steroids are indicated and ART interr uption should be considered if level of consciousness is depressed. When con- sidering corticostero id treatment cl inicians sh ould be aware of their side effects and only use them when the diagnosis of IRIS is certain. In viral forms of IRIS corticosteroids are generally avoided. Keywords HIV . AIDS . Antiretr oviral therap y . Immune recons titution inflammatory syndr ome . Tuberculosis . Cryptococcosis .

Corticosteroids Introduction During early antiretroviral therapy (ART) a proportion of patients experience deterioration due to the immune recon- stitution infla mmatory synd rome (IRIS). This proportion has been up to 25 % in some series [ 1 – 3]. IRIS manifests with inflammatory reactions, targete d at the antigens of opportunistic infections (OIs) driven by rapidly recovering G.
