INTRODUCTION Lung ultrasound (US) can be applied as point-of-care approach for diagnosis of pneumonia on AIDS patients. We compare US exams of Pneumocystis jiroveci versus other etiologies of pneumonia in critically ill patients.
METHODS All HIV/AIDS patients admitted to the ICU with pneumonia were included. The 1st US exam was performed until 72 hours after admission. Pneumonia was defined by clinical examination, laboratorial parameters and chest X-rays. Etiologic agents were defined according to appropriate cultures and serology. US was applied to 4 fields (apex, lateral middle third, anterior basal and posterior basal regions) for each hemithorax, with 2.5 MHz curved transducer. Three pneumonia patterns were defined: interstitial pneumonia, bronchopneumonia and pneumonia with consolidation. The presence of B lines, peripheral microabscesses (bronchopneumonia), consolidations and pleural effusions were compared between Pneumocystis pneumonia group (PCP) versus other etiologies.
