Effects of mechanical compression on hypertrophic scars: prostaglandin E2 release / F. Reno', P. Grazianetti, M. Cannas. - In: BURNS. - ISSN 0305-4179. - 27:3(2001), pp. 215-218. [10.1016/s0305-4179(00)00101-7]
Abstract:
An alteration in the normal process of tissue repair can lead to the formation of hypertrophic scars. The best prevention and control of hypertrophy, especially in burn scars, is achieved using elastocompression, through a mechanism not yet clarified. Various studies have shown that mechanical compression induces the release of prostaglandin E-2 (PGE(2)) and that PGE(2) increases the expression of collagenases. In this study, we evaluated the effect of mechanical compression in vitro on PGE(2) release in human normotrophic (NS) and hypertrophic (IIS) burn scars. PGE(2) basal levels in HS were significantly lower than those present in NS, and compression induced a significant increase in the release of PGE(2) in HS scar in remission (7.2 times basal level) and active stages (5.88 times basal level). This increase seemed to be only partially IL-I beta -dependent. These data suggest a role for PGE(2) in the process of hypertrophy remission induced by pressure therapy.
