[A pilot and a controlled study of the influence of ethambutol on serum urate concentration and uric acid clearance (author's transl)].

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.

Chromosome analyses in man in the course of chemoprophylaxis against tuberculosis and of antituberculosis chemotherapy with isoniazid.

Cytogenetic analyses were carried out in lymphocytes of 37 persons before and during a primary chemoprophylaxis or a preventive chemotherapy with isoniazid as well as of 30 patients suffering from active pulmonary tuberculosis before and during a chemotherapy with isoniazid in combination with two other antimycobacterial drugs. The results of the four participating research groups consistently reveal no indication for a chromosome damaging activity of isoniazid, of its metabolites in the human organism and of the administered drug regimens.

[Special diagnostic and therapeutic aspects of pulmonary histiocytosis X in twelve cases from 1969 to 1975 (author's transl)].

15 cases of histiocytosis X and 274 cases of histologically confirmed sarcoidosis were diagnosed during the investigation period from 1969 to 1975. Data of 12 adults with primary pulmonary histiocytosis X were evaluated in extenso. The necessary histological verification of diagnosis was only possible by open lung biopsy. Already in early stage small excavations were found by tomography in half of the cases. Eelvation of serum copper and of the index of leukocyte alkaline phosphatase was striking. In a single case antinuclear antibodies were proven. An intra patient comparison verifies corticosteroids suppressing the disease. On the occasion of a second lung biopsy in one case could be seen that after treatment no more histiocytosis-specific substrate was existing. Exacerbation and relapse during and after continuous long-term therapy were not observed. The features of histiocytosis X and sarcoidosis are set side by side in order to show differences and relations.
