General practitioner assistance with gold and penicillamine therapy of rheumatoid arthritis--a four year prospective study.
One hundred patients with active rheumatoid arthritis, uncontrolled by symptom relieving agents, were allocated randomly to intramuscular gold or oral penicillamine therapy. Their general practitioners (97 in all) were requested to assist with blood, urine, skin and mucous membrane monitoring. After four years, 16 patients in each treatment group remained on their original therapy, and three-quarters of these continued attending their family doctor for toxicity monitoring. Most GP monitoring problems occurred in the first six months of treatment. Sustained improvement in haemoglobin and ESR was seen in both treatment groups. Second-line drug toxicity monitoring by general practitioners allows specialist time to be diverted to rheumatological problem solving but may make it more difficult to relate rare but serious adverse adverse events to drug therapy.
