Gold vs D-penicillamine double blind study and followup

Area of Science:

• Rheumatology
• Pharmacology

Background:

• Rheumatoid arthritis is a chronic autoimmune disease.
• Gold compounds and penicillamine are disease-modifying antirheumatic drugs (DMARDs).

Purpose of the Study:

• To compare the efficacy and safety of gold and penicillamine in rheumatoid arthritis patients.
• To assess long-term outcomes and toxicity of these treatments.

Main Methods:

• Controlled, randomized, double-blind study design.
• Inclusion of 50 patients with rheumatoid arthritis.
• Long-term follow-up of 55 months.

Main Results:

• No significant differences observed in clinical outcomes, laboratory variables, or toxicity between gold and penicillamine.
• A substantial number of patients discontinued both treatments over time.
• Patients achieving remission with either gold or penicillamine often continued therapy.

Conclusions:

• Gold and penicillamine show comparable efficacy and safety profiles for rheumatoid arthritis.
• Long-term treatment adherence is influenced by disease remission.
• Penicillamine demonstrated no significant immunological toxicity in this cohort.
