Abstract
Among 103 patients with fulminant hepatic failure due to viral hepatitis, paracetamol overdose, or halothane anaesthesia, treated over a 2-year period, 23 had bacteraemia. Gram-positive organisms, mainly streptococci and Staphylococcus aureus, were isolated from 61% of patients. Escherichia coli, the main type of gram-negative organism isolated, was found in 26% of patients and was associated with a fatal outcome more often than gram-positive bacteria. The type of organism isolated was not related to the aetiology of the hepatic necrosis, the presence of renal failure, or the clinical outcome. In the 23 patients with bacteraemia the same organism was isolated from other sites of infection, including sputum in four, urine in two, and the central venous catheter and arteriovenous shunt in one. Bacteraemia usually occurred 3 days after admission or on average 2 days after clinical deterioration to grade IV encephalopathy had begun. In 11 patients, the infection had an adverse effect on their clinical course, in three patients being implicated as a cause of the encephalopathy. Although in four patients the development of infection after all signs of encephalopathy had cleared may have been a major factor in their death, two of these patients had evidence of severe sepsis, pneumococcal peritonitis, and renal abscesses from which Candida albicans was cultured. An awareness of infection as a complication both of the acute stage of the illness and during recovery is essential if early detection and treatment are to be effective.
