Pneumocystis Jirovecii Pneumonia

Pneumocystis Jirovecii Pneumonia

Pneumocystis jirovecii pneumonia (PJP) is an infection caused by the fungus Pneumocystis jirovecii. It affects the airways of the lungs, and is typically seen in people who have a weakened immune system due to HIV infection, cancer, or are taking other immunosuppressive medications. Pneumocystis pneumonia is also known as PCP.

Common symptoms of PJP can include:

  • Cough, usually dry
  • Shortness of breath
  • Fever
  • Loss of appetite
  • Weight loss
  • Fatigue

Diagnosis of PJP is usually done by a chest X-ray or computed tomography scan, as well as bronchoalveolar lavage, or BAL. Treatment is typically with oral or intravenous antibiotics such as trimethoprim/sulfamethoxazole, or pentamidine.

Prevention of PJP is also important, especially in people with weakened immune systems. Adequate nutrition, good flow of oxygen to the lungs, and other preventive measures can help reduce the risk of infection.

Pneumocystis pneumonia is an important infection to recognize and address. Prompt diagnosis and treatment can help reduce the severity of the infection and improve outcomes.
