PCP pneumonia is an inflammation of the lungs caused by Pneumocystis carinii, which is contagious.
Pneumocystis carinii, also known as Pneumocystis japonicus, belongs to fungal pathogenic microorganisms, which are widely found in nature, and can be infected through airborne transmission, person-to-person contact, and the source of infection can be the patient himself or herself or the infected person. It mostly occurs in immunocompromised or immunologically limited people, such as patients with AIDS, organ transplantation, tumors and heavy use of immunosuppressants.
The main symptoms of PCP pneumonia are dyspnea combined with high fever and extensive lesions on CT of the lungs, but no obvious signs on physical examination. Once the diagnosis is confirmed, the first step is to have bed rest, strengthen nutrition, improve immunity, and those with respiratory distress should be given oxygen in time to improve ventilation, and given active treatment with anti-Pneumocystis carinii drugs such as sulfamethoxazole/metronidazole and pentamidine.
If the patient is co-infected with bacterial infection, antibacterial drugs such as penicillin, cefotaxime and levofloxacin should be chosen. If the treatment effect is not good, echinocandin-like drug caspofungin can be added for treatment.
All of the above drugs should be used under the guidance of a doctor.
