Аннотация
BACKGROUND: Castleman diseases encompass three distinct entities: unicentric Castleman disease, KSHV/HHV-8-associated multicentric Castleman disease (MCD), and idiopathic MCD. HHV-8 MCD is a life-threatening B-cell lymphoproliferative disorder driven by KSHV/HHV-8 infection of B cells, resulting in systemic inflammation and diverse clinical phenotypes.
OBJECTIVE: To summarize current knowledge of HHV-8 MCD pathogenesis, clinical presentations, autoimmune complications, and diagnostic advances.
METHODS: This review synthesizes existing literature on HHV-8 MCD, with particular attention to emerging diagnostic techniques, including liquid-phase detection of circulating viroblasts.
RESULTS: Treatment approaches center on rituximab-based regimens, with outcomes varying between HIV-positive and HIV-negative populations. Novel diagnostic tools combining flow cytometry and viral transcript detection offer rapid identification of disease flares.
CONCLUSION: These emerging diagnostic approaches may improve management of HHV-8 MCD, particularly in emergency settings where rapid flare identification is critical.
