Cryptococcus neoformans commonly causes opportunistic infections in immunocompromised patients, especially in patients with AIDS. CD4+ T-lymphocytopenia in AIDS indicates an increased risk of opportunistic infection and a decline in immunological function. Idiopathic CD4 T-lymphocytopenia (ICL) is characterized by depletions in the CD4+ T-cell subsets, without evidence of HIV infection. Immunodeficiency can exist in the absence of laboratory evidence of HIV infection, and T-cell subsets should be evaluated in patients who present with unusual opportunistic infections. We report a case of pulmonary cryptococcosis and lung cancer in a patient with persistently low CD4+ cell counts, without evidence of HIV infection.

OBJECTIVETo investigate the therapeutic effects of Aiyishu Injection (AYSI) on cancerous hydrothorax, quality of life (QOF), and cellular immune function of patients.

METHODSSixty late-stage cancer patients accompanied hydrothorax were randomly divided into the experimental group (EG) and the control group (CG), with thirty patients in each group. After thoracenteses being carried out in all patients for draining off hydropsy, to the patients in EG, AYSI was medicated, 50 ml by intrathoracic and another 50 ml by intravenous injection; while to the patients in CG chemotherapeutic agent or interleukin-2 (IL-2) was given. The same treatment, thoracentesis and medication, was repeated 3 days later. After 4 weeks, the volume of pleural effusion was measured with B-mode ultrasound to evaluate the therapeutic effects of AYSI. QOF, body weight and T-lymphocyte subsets were compared between the two groups before and after treatment.

RESULTSThe clinical efficacy was significantly higher in EG than that in CG (P < 0.01). Besides, QOF was significantly improved (P < 0.05) and levels of CD3+ , CD4+ , CD4+ /CD8+ in peripheral blood increased in EG after treatment, which were significantly different to those in CG (P < 0.01, P < 0.05).

CONCLUSIONAYSI has definite therapeutic effects on cancerous hydrothorax, it could improve QOF and cellular immune function in patients with cancer.
