简要总结
At present, pulmonary diffusion and target antifungal concentrations for APC in patients with sarcoidosis or chronic obstructive pulmonary disease (COPD) are unknown.
详细描述
Knowledge of these elements is however an essential prerequisite for optimizing the dosages in these contexts. The main objective of the study is to quantify the diffusion of antifungals in the lower respiratory tract in patients treated for pulmonary aspergillosis in the context of underlying chronic respiratory disease. Determining this level of diffusion will make it possible to deduce the plasma concentrations to be achieved in patients and to identify the molecules with the best diffusion profile. The concentration of antifungals in the lungs will be measured from 3 types of samples:
- Sputum obtained by expectoration. These samples will make it possible to quantify the diffusion at the level of the upper and lower respiratory tree.
- Bronchial aspirations. These samples will make it possible to quantify the diffusion at the level of the deep respiratory tree.
- Bronchoalveolar lavage fluid, which will quantify the diffusion at the level of the deep respiratory tree and the ELF.
Blood samples will be taken simultaneously so as to determine the percentage of diffusion from the plasma to the lung.
All these samples will be taken as part of the standard care of patients, the lung samples having the main use of mycological monitoring, the blood samples having the main use of pharmacological and serological monitoring. Lung samples will also be taken routinely for pharmacological monitoring, in order to measure antifungal concentrations at the site of infection.
Mycological monitoring will consist of measuring the fungal load in the broncho-respiratory secretions as well as carrying out an antifongigram in the event of isolation of Aspergillus spp.
