  • Title: Serum stimulatory activity and polymorphonuclear leucocyte movement in patients with fulminant hepatic failure.

    Journal: Clin Exp Immunol; 1982 Nov; 50(2):442-9. PubMed ID: 7151333.
    Abstract:
    Serum from 27 patients with fulminant hepatic failure and grade IV encephalopathy had reduced ability to stimulate the movement in vitro of normal polymorphonuclear leucocytes. All patients had a deficiency of serum complement factors C3 and C5 and there was a significant positive correlation between C5 and serum stimulatory activity. However, in addition to this complement defect, serum from 22% of patients contained an antagonist to normal serum stimulatory factors. This antagonism was attributed to at least two different substances in the serum on the basis of differences in heat lability, dialysability and action on complement factor C5a. Polymorphonuclear leucocytes from eight of 13 patients had reduced movement toward serum, but serum from only one patient contained an antagonist acting on the cells; this was probably related to an underlying carcinoma of the breast. During the early stages of clinical recovery, serum stimulatory and complement activity returned to normal. These serum and cellular defects have not been reported previously in patients with fulminant hepatic failure and represent major defects in the body's defenses against bacterial infection.
