Prognosis becomes poorer in the presence of co-morbidities, such as diabetes mellitus, immunosuppression, chronic alcohol disease, chronic renal failure, and liver cirrhosis.

Furthermore, kallistatin treatment was reported to reduce vessel leakage, bacteremia, and liver pathology after local infection.
