The aim of work was the assessment of plasma anion oxalate (Ox) concentration in children during antibacterial treatment depending on way and time of antibiotic administration.
METHODS
The examinations were carried out in 80 children, without nephrolithiasis, aged 10.1 +/- 4.3 years with bronchopneumonia, treated with beta-lactame antibiotics. The children were divided in two groups: I--children treated with oral amoxicillin + clavulanic acid or cefuroxime axetil (n=40), II--children treated with the same antibiotics intravenously (n=40). The Ox concentration in plasma and urine was measured using an enzymatic method with oxalate oxidase, four times. (0)--before treatment, (a)--in third day and (b)--in last day of administration (10 to 14 day), (c)--3 weeks after finishing treatment with antibiotics.
RESULTS
The result showed that in children before treatment (0) mean plasma Ox concentration was 2.439 +/- 0.645 micromol/l. In 3rd day (a) the Ox concentration increased to 7.848 +/- 0.999 micromol/l (p < 0.01), in last day of treatment (b) decreased to 5.681 +/- 0.871 micromol/l, and after 3 weeks (c) came back to initial values (p > 0.05). Intravenous antibiotics administration did not influence plasma Ox concentration.
CONCLUSIONS
Plasma oxalate concentration increases during oral administration of beta-lactame antibiotics caused by increased intestinal absorption, as a result of saprophytic microflora deterioration. However intravewous administration of the same antibiotics does not change the concentration of plasma oxalate.
