Diagnosis and Management of Castleman Disease
Insights
Castleman disease treatment varies by type. HHV8-associated Castleman disease is treated with rituximab, while idiopathic Castleman disease prefers siltuximab. Antiretrovirals are essential for HIV-positive patients.
Area of Science:
- Hematology
- Oncology
- Immunology
Background:
- Castleman disease is a rare, nonmalignant lymphoproliferative disorder.
- Key distinctions include unicentric vs. multicentric presentation, pathological subtypes (hyaline vascular, plasmacytic, mixed), and HHV8-association (often HIV-positive) versus idiopathic forms.
Abstract:
Castleman disease is a heterogeneous nonmalignant lymphoproliferative disorder. Major distinctions include unicentric versus multicentric presentation; hyaline vascular, plasmacytic, or mixed pathology; and HHV8-associated (typically HIV-positive) versus idiopathic disease. At the NCCN 2019 Annual Congress: Hematologic Malignancies, Dr. Jeremy S. Abramson stated that rituximab is preferred as initial therapy for HHV8-positive disease, and chemotherapy can be added for patients with fulminant disease (antiretrovirals should always be used as well for those who are HIV-positive). Siltuximab is the preferred frontline therapy for idiopathic disease.
