Filter by:Aerosol antibiotic administration offers the theoretical advantages of achieving high drug concentration at the infection site and low systemic absorption, thereby avoiding toxicity. Antibiotic aerosolization has good results in patients with cystic fibrosis, but data are scarce for patients under mechanical ventilation. Prospective, randomized 1:1, open-label study to assess the microbiological cure and pharmacokinetics (PK), safety and efficacy of nebulized Aztreonam lysine (75 mg dose) each 8 hr during 5 days in ventilated patients heavily colonized by Gram-negative bacteria. It is planned to include a total of 20 ventilated patients heavily colonized. Only ten of them (active group) will receive 5 days of treatment with nebulized AZLI.The control group will not receive treatment.
A critical need exists for efficient community-based interventions aimed at reduction of environmental exposures relevant to health. Biomass smoke exposures due to residential wood heating are common among rural Native American communities, and such exposures have been associated with respiratory disease in susceptible populations. In many of these communities wood stoves are the most economic and traditionally preferred method of residential heating, but resource scarcity can result in burning of improper wood fuels and corresponding high levels of indoor particulate matter. Community-based participatory research techniques will be used to adapt intervention approaches to meet the cultural context of each participating community. At the community level, investigators will facilitate local development of a tribal agency-led wood bank program ensuring that elderly and/or persons with need have access to dry wood for heating. At the household level, investigators will use a three arm randomized placebo-controlled intervention trial to implement and assess education/outreach on best burn practices (Tx1). The content and delivery strategies of the education intervention will be adapted to each community according to stakeholder input. This educational intervention will be evaluated against an indoor air filtration unit arm (Tx2), as well as a placebo arm (Tx3, sham air filters). Tx3 will be used in comparison with the other two treatment arms to evaluate the penetration and efficacy of the community-level wood bank program. Outcomes will be evaluated with respect to changes in pulmonary function measures and respiratory symptoms and conditions among household elders. The investigators hypothesize that locally-designed education-based interventions at the community and household levels will result in efficacious and sustainable strategies for reducing personal exposures to indoor particulate matter, and lead to respiratory health improvements in elderly Native populations. This study will advance knowledge of cost-effective environmental interventions within two unique Native American communities, and inform sustainable multi-level strategies in similar communities throughout the US to improve respiratory health among at-risk populations.
