ABSTRACT
INTRODUCTION: Deficiency or impaired activity of alpha-1-antitrypsin (AAT), which neutralizes multiple proteolytic enzymes, such as collagenases and elastases may result in significant tissue autodigestion. Hence, AAT may have a role in the healing process in chronic and acute inflammation including skin infection, such as cellulitis. AIM: The aim of this study was to evaluate the role of AAT activity and inflammatory markers in patients with cellulitis. METHODS: The study included eleven consecutive patients (6 males and 5 females, mean age 68.5 ± 4.5 years) who were hospitalized for cellulitis between 09/2009-02/2010. We analyzed tests results for C reactive protein (CRP), AAT level and activity that were obtained on admission (T1), 2 days after admission (T2) and 2 weeks after admission (T3). RESULTS: AAT levels were found to be within the normal range. AAT activity values were found to be within or above the normal range. The highest activity values were measured after 2 days of treatment and the lowest values were measured after 2 weeks of treatment. CRP values were highest on admission and lowest, as expected, after the end of treatment 2 weeks later. AAT activity values were significantly lower statistically in patients with unresolved cellulitis 2 weeks after treatment began. SUMMARY: AAT activity was significantly lower statistically in patients who suffered from slow resolving cellulitis 14 days after hospitalization. This possibly suggests a role AAT activity may have in the inflammation cascade in patients with cellulitis. Further studies are needed to evaluate the role of AAT activity in the inflammatory process.
