sultamicillin and Liver-Diseases

Sulbactam is a new beta-lactamase inhibitor with pharmacokinetic characteristics in humans similar to those of ampicillin. A total of 41 patients hospitalized in the Clinic of Infectious Diseases, University of Naples, for chronic liver diseases, were treated with sulbactam/ampicillin (ratio 1:2) for urinary, respiratory, biliary tract or soft tissue infections. Sulbactam/ampicillin was administered im or iv at a dosage of 3-9 g/day depending on the site and severity of the infection. All the patients treated with sulbactam/ampicillin had clinical signs and symptoms of infection, and all the organisms isolated were sensitive to sulbactam/ampicillin (MIC less than 16 mg/l). For both Gram-positive and Gram-negative bacteria the sulbactam/ampicillin MICs were much lower than the ampicillin MICs. In agreement with the favourable in-vitro results, we observed good therapeutic efficacy. 85% of the patients recovered or improved within a few days of therapy, with no clinical relapses, and in 81% of the infections the responsible bacteria were completely eradicated. We observed a low number of side effects (3/41 oral candidosis; 3/41 pain at the im injection site) and no change in the blood chemistry tests.
