Filter by:OBJECTIVES: I. Determine the safety and efficacy of tobramycin in patients with cystic fibrosis who are chronically colonized with Pseudomonas aeruginosa. II. Determine whether this treatment produces tobramycin-resistant bacteria at a frequency different from the placebo group and whether the emergence of resistance is associated with a lack of clinical response.
OBJECTIVES: I. Assess the efficacy of monthly intravenous mucoid exopolysaccharide Pseudomonas aeruginosa immune globulin (MEP IGIV) given over 1 year in reducing the frequency of acute pulmonary exacerbation in patients with cystic fibrosis, mild to moderate pulmonary disease, and mucoid P. aeruginosa colonization. II. Assess the effect of MEP IGIV on FEV1, sputum density of mucoid P. aeruginosa, and the quality of life in these patients. III. Assess the safety of monthly MEP IGIV. IV. Assess population-based MEP IGIV pharmacokinetics during chronic therapy.
To assess the dose proportionality of azithromycin concentrations and toleration when delivered in tablet formulation to HIV-infected patients. The need exists to further assess the antibacterial agent azithromycin at differing doses in an HIV-infected population.
To compare the uptake of azithromycin in white cells relative to plasma concentrations in HIV-infected patients.
To determine the effects of fluconazole and either rifabutin or clarithromycin, alone and in combination, on the pharmacokinetics of first sulfamethoxazole-trimethoprim and then dapsone in HIV-infected patients. Although prophylaxis for more than one opportunistic infection is emerging as a common clinical practice in patients with advanced HIV disease, little is known about possible adverse drug interactions. The need exists to define pharmacokinetics and pharmacodynamic adverse interactions of the many combination prophylactic regimens that may be prescribed.
This study compares 2 different treatments administered to try to prevent serious bacterial infections (such as pneumonia) in HIV-positive children. A combination of drugs (azithromycin plus atovaquone) will be compared to sulfamethoxazole-trimethoprim (SMX/TMP) alone. This study also evaluates the long-term safety and tolerance of these different drugs. SMX/TMP is a commonly prescribed drug for the prevention of bacterial infections. However, the combination of azithromycin and atovaquone may be safer and more effective than SMX/TMP. This study compares the 2 treatments.
