Serum cytokines associated with severity and complications of kala-azar

Abstract

In its severe form, kala-azar, a neglected tropical disease, initiates a systemic inflammatory response that leads to DIC and other manifestations. Children may have higher risk of death due to the more intense cytokine release. The data supports the notion that IL-6 is the central cytokine that is associated with lethal disease, but interferon-gamma, IL1beta, IL-8, and TNF-alpha are also involved with disease severity. Inhibition of IL-6 is a potential target of adjuvant therapy for severe or pediatric forms of this disease.
