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.

Chronic pain is a common condition for which patients seek care from various health-care providers. This type of pain causes much suffering and disability and is frequently mistreated or undertreated. Patients who present for evaluation for chronic pain should undergo a careful assessment before therapy. ⋯ These patients suffer from a chronic condition and often require long-term care, with frequent reassessment and adjustment of therapy. Although cure is possible, it is also infrequent. Therefore, therapy is provided with the aim of decreasing pain and suffering while improving physical and mental functioning.

Randomized Controlled Trial Clinical Trial
Long-term effect of inhaled budesonide in mild and moderate chronic obstructive pulmonary disease: a randomised controlled trial.
Little is known about the long-term efficacy of inhaled corticosteroids in chronic obstructive pulmonary disease (COPD). We investigated the efficacy of inhaled budesonide on decline in lung function and respiratory symptoms in a 3-year placebo-controlled study of patients with COPD. ⋯ Inhaled budesonide was of no clinical benefit in COPD patients recruited from the general population by screening. We question the role of long-term inhaled corticosteroids in the treatment of mild to moderate COPD.
