An Antithrombin III product containing biologically active hepatocyte growth factor may be beneficial in deep ulcer infections.
BACKGROUND
Widely studied for the past 20 years, hepatocyte growth factor (HGF) has been identified as a regenerative marker and an important factor in the development and healing of injuries. Antithrombin III (AT III) is a protein in the blood stream with anti-thrombotic and anti-inflammatory properties and has been used as an adjuvant treatment along with antibiotics in severe sepsis.


OBJECTIVE
To study the content and properties of HGF in plasma-derived AT III products, and the regenerative effect in severe deep ulcer infections.


METHODS
Commercial AT III products were analyzed for the presence and biological activity of HGF. One AT III product containing biologically active HGF was used to treat 18 cases of critical, deep ulcer infections scheduled for major invasive intervention. The patients were followed up for 6-60 months.


RESULTS
The AT III products contained HGF with different biological activity. No adverse reactions were observed after local administration of AT III during the study or follow-up period. In 16 of 18 cases no surgical intervention was needed within the first 6 month of inclusion.


CONCLUSIONS
AT III products containing biologically active HGF may contribute to regeneration and healing in severe deep ulcer infections which do not respond adequately to different combinations of antibiotics alone.
