Levamisole is an antihelminth drug and a common cocaine contaminant, present in an estimated 71% of cocaine samples in the US. Levamisole-contaminated cocaine has been linked to an ANCA-associated vasculitis with cutaneous, renal, and pulmonary manifestations. We report the case of a 46 year old woman with known cocaine exposure who presents with recurrent, large purpuric and maculopapular rash of the extremities and face and review existing cases of levamisole/cocaine-associated ANCA vasculitis, We summarize the clinical presentation, treatment, and outcomes of levamisole induced vasculitis. There is emerging research on pathogenesis relating to neutrophil extracellular traps (NETs). We review studies implicating role of NETs in the pathogenesis of levamisole induced vasculitis. Further research to explore the use of NETs as therapeutic targets in drug induced vasculitis is needed.

Cocaine-induced Vasculitis: Uncommon Manifestations in the Lower Extremities - A Case Report.

Levamisole-induced vasculitis is a recognized dermatopathologic phenomenon frequently observed in individuals engaged in illicit substance use, particularly cocaine. Levimasole's structural resemblance to cocaine leads to its utilization as a cutting or bulking agent, creating an illusion of unaltered purity. While this vasculitis typically manifests in cartilaginous areas such as the ears and nose, it can also occur, though less commonly, in the lower extremities.

Angiogenic T cells (Tang) are crucial in promoting angiogenesis, with the loss of CD28 serving as a marker for highly differentiated and senescent T cells. This study aims to investigate the characteristics and potential roles of CD8CD28 Tang in patients with ANCA-associated vasculitis (AAV). A cohort of AAV patients and matched healthy controls (HCs) were analyzed.

Objective: To explore the influence of respiratory infections on the onset of Henoch-Schönlein Purpura (HSP) in children, along with exploring potential underlying mechanisms.
Method: The present study conducted a statistical analysis on renal involvement indicators in 296 children with HSP who came to the Children's Hospital of Zhejiang University, as well as the IgA levels in 400 children with respiratory infections and 400 children with HSP.
Results: Compared with the control group, children with HSP exhibited a significant increase in urine red blood cell count, urine microalbuminuria, and urine protein/creatinine ratio (P < 0.

Patients with A20 haploinsufficiency (HA20) presenting with central nervous system (CNS) symptoms are rare, and available reports are limited. Here, we describe a patient with HA20, previously followed up as Behçet disease, who presented with CNS symptoms in adulthood. A 38-year-old Japanese male who had been followed up for incomplete Behçet disease at another hospital since 28 years of age presented to our hospital with acute-onset diplopia and persistent hiccups that were severe enough to cause vomiting.
