PET Imaging and Lymph Node Assessment of IRIS in People With AIDS

Background: \- Sometimes people with HIV, the virus that causes AIDS, can have new or worsening symptoms soon after starting HIV medications. Often these symptoms are caused by immune reconstitution inflammatory syndrome (IRIS). Researchers want to study why and how people develop IRIS and how best to prevent and treat it.
