[Enzymological evaluation of the hepatotoxicity of ampicillin and its therapeutic form, roscillin, in the treatment of pyelonephritis in pregnancy].

The combined enzymological investigation including determination of the total activity of asparagine transaminase and alanine transaminase, two serum enzymes, alkaline phosphatase, gamma-glutamyl transpeptidase, acetyl cholinesterase, and butyryl cholinesterase was applied to two groups of pregnant women with pyelonephritis treated with ampicillin (12 patients) and roscillin (14 patients). The investigation was performed at the following stages: before the treatment, on the 7th and on the 12th day of the treatment. No statistically significant differences in the average values of the activity of the above enzymes at these stages were observed in patients of the both groups which indicated the absence of the hepatotoxic effect of the preparations on the patients of a group as a whole. An increase in the levels of transaminases recorded in some patients after discontinuation of the treatment course was evident of a possible cytotoxic effect of the drugs without the signs of cholestasis. The effect was connected with the initial functional renal insufficiency.
