Three tricks to determine whether there is pneumocystis carinii pneumonia

Pneumocystis pneumonia, also known as pneumocystis carinii (referred to as card lung) or PCP, is seen in immunodeficient patients, such as after tumor chemotherapy, long-term use of hormones or immunosuppressants, and chronic liver disease nephropathy and diabetes and other immunodeficiency, most commonly in patients with advanced AIDS.

First, whether to suffer from PCP first depends on whether there is the above immunodeficiency situation, if not, it will not generally suffer from PCP. Of course, some AIDS patients cannot provide a relevant medical history without knowing that they are infected with AIDS.

Second, CD4 is less than 200/uL, generally less than 100/uL. Most are seen in HIV-positive patients, but immunodeficiency (low CD4) and leukopenia can occur for other reasons.

3. Fever, cough, and wheezing. Happens unconsciously. Cough is generally sputumless, and asthma gradually worsens, and can be high or low fever.

Fourth, the chest image can see the extensive blurred shadow of the two lungs (ground glass), not the nodule cord or the local flaky shadow. Blood leukocytes are generally normal, and in some severe cases, elevated blood lactate dehydrogenase may be seen.
