[Long-term therapy with amoxicillin and clavulanic acid in recurrent urinary tract infections in childhood].

Experiments have been carried out with an association of amoxicillin and clavulanic acid for the long-term treatment of recurrent urinary tract infections. 20 children whose antibiogram showed that the microbe in question was insensitive to amoxicillin alone were selected for treatment; five suffered from urinary tract malformations. Urine sterilisation was obtained by administering a dose of 40 mg/kg/die for five days. Treatment continued with a single evening dose of 20 mg/kg for six months. A positive result was obtained in 18 subjects (90%). One case of E. coli proved resistant to the antibiotic. In another case, treatment had to be suspended for vomiting. At the end of treatment, haematological controls proved normal.
