Bronchoalveolar Lavage Fluid clinical trials

Aspergillosis Detection Via EBC-GM in Ventilated Patients

Brief Research Proposal: Non-Invasive Detection of Invasive Pulmonary Aspergillosis in ICU Patients Background: Invasive Pulmonary Aspergillosis (IPA) is a critical threat to patients in ICUs, especially those undergoing mechanical ventilation. Traditional diagnostic methods are invasive and carry risks. This study proposes a non-invasive, innovative approach utilizing galactomannan (GM) analysis in Exhaled Breath Condensate (EBC) for early IPA detection. Objective: To evaluate the diagnostic accuracy of measuring GM levels in EBC for detecting IPA in mechanically ventilated patients, comparing it against the conventional Bronchoalveolar Lavage Fluid (BALF)-GM measurements. Methods: A clinical trial will be conducted with 75 mechanically ventilated patients suspected of having IPA. The study will compare the effectiveness of EBC-GM levels against BALF-GM levels in diagnosing IPA, focusing on sensitivity, specificity, and diagnostic accuracy. The novel, self-designed EBC collection device will facilitate the safe and efficient collection of EBC from patients. Expected Outcomes: Validation of EBC-GM Diagnostic Accuracy: Anticipate demonstrating that EBC-GM levels provide a comparable diagnostic accuracy to BALF-GM, establishing a non-invasive, safer alternative for IPA detection. Implementation of a Non-Invasive Diagnostic Tool: The study aims to introduce a non-invasive diagnostic approach that can potentially replace more risky, invasive methods, improving patient care in ICUs. Contribution to Clinical Practice: By providing a new method for early and safer detection of IPA, the study is expected to influence clinical guidelines and practices in the management of critically ill, ventilated patients. Significance: This research has the potential to revolutionize the diagnosis of fungal infections in critically ill patients by offering a non-invasive, accurate, and safer diagnostic tool, thereby improving patient outcomes and reducing the risks associated with invasive diagnostic procedures.
