IBCC Episode 86 - PJP Pneumonia | The Internet Book of Critical Care Podcast

The podcast addresses Pneumocystis Jirovicii Pneumonia (PJP), differentiating between its presentation in HIV-positive and HIV-negative patients. It highlights that HIV-positive PJP typically manifests as a slow, indolent process with a high organism burden, while HIV-negative PJP presents more acutely with greater lung inflammation despite fewer organisms. The discussion covers diagnostic approaches, emphasizing the utility of CT scans for identifying ground glass opacities and cysts, and the role of serum beta-D-glucan levels in assessing organism load. The speakers also explore treatment strategies, including the use of steroids and trimethoprim-sulfamethoxazole, while cautioning against the over-reliance on bronchoscopy in unstable patients.
