Randomized Controlled Trial Multicenter Study Clinical Trial
Acquired rifamycin monoresistance in patients with HIV-related tuberculosis treated with once-weekly rifapentine and isoniazid. Tuberculosis Trials Consortium.
Rifapentine is a cyclopentyl-substituted rifamycin whose serum half-life is five times that of rifampin. The US Public Health Service Study 22 compared a once-weekly regimen of isoniazid and rifapentine with twice weekly isoniazid and rifampin in the continuation phase (the last 4 months) of treatment for pulmonary tuberculosis in HIV-seropositive and HIV-seronegative patients. This report concerns only the HIV-seropositive part of the trial, which has ended. The HIV-seronegative part will stop follow-up in 2001. ⋯ Relapse with rifamycin monoresistant tuberculosis occurred among HIV-seropositive tuberculosis patients treated with a once-weekly isoniazid/rifapentine continuation-phase regimen. Until more effective regimens have been identified and assessed in clinical trials, HIV-seropositive people with tuberculosis should not be treated with a once-weekly isoniazid/rifapentine regimen.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of combination therapy with single-drug therapy in early rheumatoid arthritis: a randomised trial. FIN-RACo trial group.
The treatment of rheumatoid arthritis should aim at clinical remission. This multicentre, randomised trial with 2-year follow-up sought evidence on the efficacy and tolerability of combination therapy (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) compared with treatment with a single disease-modifying antirheumatic drug, with or without prednisolone, in the treatment of early rheumatoid arthritis. ⋯ Combination therapy was better and not more hazardous than single treatment in induction of remission in early rheumatoid arthritis. The combination strategy as an initial therapy seems to increase the efficacy of the treatment in at least a proportion of patients with early rheumatoid arthritis.
