Abstract
Ethambutol is said to be capable of elevating serum urate concentration. This statement was reconsidered in three investigations using strictly supervised administration of ethambutol in a single daily dose of 25 mg. per kg. of body weight: (1) In short term administration 10 healthy subjects received ethambutol for eight days. (2) In a pilot study 13 patients suffering from pulmonary tuberculosis were treated with a triple combination including thambutol for six months. (3) In a controlled trial 23 patients were randomly allocated to one of the following regiments: In the first group patients received ethambutol plus isoniazid plus rifampicin for six months. In the second group patients received streptomycin plus isoniazid plus PAS for three months and thereafter streptomycin plus isoniazid plus ethambutol for another three months. Serum urate concentrations and clearances of uric acid and of creatinine were determined periodically in all subjects. A slight increase in serum urate concentration occurring in long term therapy showed no relation to ethambutol administration, but was obviously dependant on parameters related to the course of the disease in form of increase in body weight and physical activity, or related to the well known syntropy of chronic alcoholism and tuberculosis.
