Levamisole‐contaminated cocaine toxicity is a serious emerging public health concern, and providers should be aware of its presentation and management. Most cases of levamisole‐induced vasculitis/vasculopathy (LIV) are associated with high antineutrophil cytoplasmic antibodies (ANCA). We describe a unique case of a cocaine user who presented with an acute purpuric eruption and negative ANCA laboratory findings. A brief clinical overview of LIV, spanning from patient presentation to treatment, is provided. In addition, we present a summary of all cases of ANCA‐negative vasculitis identified via a PubMed literature review.
Hantavirus infection, traditionally associated with Hantavirus Pulmonary Syndrome in critically ill adults, has been described in less severe illness with resultant cardiopulmonary consequences, particularly in strains endemic to Texas. Characterized by pulmonary infiltrates and azotemia, cardiomyopathy is a feared complication of acute disease. Systemic Lupus Erythematosus (SLE), a pathology of diffuse inflammation, may serve as a predisposition to the development of viral sequelae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
