One hundred and thirty-three patients with asthma were treated with auro-thioglucose (Romosol).
1) The treatment was continued for a period longer than one year in 31 of the 133 cases. Clinical effects were evaluated from changes in severity of asthmatic symptoms before and after the administration of auro-thioglucose. Good results were obtained in 23 (74.2%) of 31 cases, including excellent results in 9 (29.0%).
2) The effects of the drug appeared after the cumulative dose had amounted to approximately 300mg, to which it takes about 3 months from the start of the treatment. Clinical effects were manifest within 6 months in 15 cases (65%), and between 6 months and one year in 3 cases (35%). Increased effectiveness of the drug after the lapse of 6 months was observed in 4 cases (17%).
3) The level in plasma gold content at one week after an intramuscular injection showed a small amount of increment compared to the level of one week before in the cases with a less cumulative total of the drug, while in the cases with a cumulative total of more than 300 mg no increment in the level of plasma gold content was observed at each week measurement.
The plasma gold content were: when given 10 mg, up to 150 μg/dl; when given 25 mg, 150 to 250 μg/dl; when given 50 mg, 250 to 350 μg/dl.
4) The side effects observed were: proteinuria (mostly evanescent) in 44 %; skin disorders in 56 %; stomatitis in 9 %; that is, almost the same as previously repoted with other kinds of gold preparation. The treatment with this preparation had to be withdrawn because of the side effects in 21 cases (15 %).
5) Considering the side effects, the dosage of this preparation should be kept at the minimal effective amount, by evaluating clinical effects against accumulation of gold, and speed of excretion in individual cases.
