Treatment of lymphatic malformations of head and neck with OK-432 sclerotherapy induce systemic inflammatory response.
Systemic immune responses after OK-432 (Picibanil) sclerotherapy in patients with head and neck lymphatic malformations (LM) were examined to achieve a better understanding of the mechanism of OK-432 sclerotherapy and to evaluate the long-term treatment outcome. Serum samples from 17 consecutive patients with head and neck LMs were collected during a total of 26 OK-432 treatment episodes. Serum C-reactive protein (CRP), interleukins (IL) 1β, 6, 8, 10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, RANTES, immune protein (IP)-10 and macrophage chemoattractant protein (MCP)-1 as well as blood leukocyte counts were determined. Clinical outcome of the treatment was evaluated at the last visit and from patient files. Elevated serum levels of IP-10 (means at baseline 702 ng/L, after 1 day 1180 ng/L, after 4 weeks 691 ng/L) were seen on day one after OK-432 sclerotherapy (p < 0.05). C-reactive protein and leukocyte counts 1 day after treatment differed statistically significantly (p < 0.05) from the baseline. No significant differences with other cytokines investigated were observed. Patients with macrocystic LM responded better than patients with microcystic LM (p = 0.01). The elevated levels of IP-10, C-reactive protein and leukocyte levels indicate that OK-432 sclerotherapy induces systemic immune responses in patients with LM. The mechanisms of OK-432 sclerotherapy are still not precisely understood, but the IP-10 elevation may reflect local antiangiogenetic properties of immunoactivation induced by OK-432.
