From Head to Toe: Granulomatosis with Polyangiitis.

Granulomatosis with polyangiitis (GPA) is an antineutrophil cytoplasmic antibody-associated vasculitis. It is an uncommon multisystem disease involving predominantly small vessels and is characterized by granulomatous inflammation, pauci-immune necrotizing glomerulonephritis, and vasculitis. GPA can involve virtually any organ.

Myocardial Inflammatory Changes Before and After Antiretroviral Therapy Initiation in People With Advanced Human Immunodeficiency Virus Disease.

Because of the high frequency of late presentation of human immunodeficiency virus (HIV) disease in our population, we decided to explore the presence of myocarditis among people with HIV infection and advanced immunosuppression (less than 200 CD4 cells/μL) and to describe the inflammatory changes observed after combined antiretroviral therapy initiation in an observational, longitudinal, prospective cohort. We performed both cardiovascular magnetic resonance imaging and doppler transthoracic echocardiogram.
