Fibronectin and Kupffer cell function in fulminant hepatic failure
The relationship between plasma fibronectin, in vitro plasma opsonic activity, which measures the biological activity of fibronectin, and in vivo Kupffer cell function, as assessed by the systemic clearance of microaggregated ( SVI)albumin, were determined simultaneously in 15 patients with fulminant hepatic failure and 12 normal subjects. Both the plasma fibronectin and plasma opsonic activity were significantly reduced in patients with fulminant hepatic failure, while the systemic clearance of microaggregated albumin was decreased. There was a significant correlation between plasma fibronectin and the plasma opsonic activity on admission, but no correlation could be detected between either parameter and the clearance of microaggregated albumin. A gelatin-derived plasma expander was shown to block the plasma opsonic activity both in vitro and in vivo. The low plasma fibronectin and decreased clearance of microaggregated albumin in fulminant hepatic failure reflect different aspects of the overall impairment of Kupffer cell function.
