Clinical features of pneumocystis pneumonia in non-human immunodeficiency virus-infected patients: A systemic review and meta-analysis
Abstract
Objectives: Pneumocystis pneumonia (PCP) is an opportunistic disease that causes potentially fatal pneumonia in immunocompromised individuals. The clinical features of PCP without HIV remain incompletely understood. Methods: This study aimed to identify the clinical features of PCP without HIV in a systematic review following a meta-analysis. Results: 65 articles that included 10,133 PCP patients without HIV infection were enrolled. PCP occurred most commonly at age 59.2 years (95%CI: 57.7, 60.7) in a gender ratio of approximately 3 to 2 (males to females). Dyspnea, fever, cough, and sputum were nonspecific clinical findings in 73% (95%CI: 69, 79), 73% (95%CI: 65, 81), 56% (95%CI: 48%, 64%), and 32% (96%CI: 16, 48) of patients, respectively. Viral, bacterial, and fungal co-infection were observed in 28% (95%CI: 13, 44), 19% (95%CI: 13, 25), and 11% (95%CI: 6, 16) of patients, respectively. Laboratory data showed a trend of elevated WBC, LDH, CRP, β-D glucan, and KL-6. Ground glass opacity (GGO) was found in 87% (95%CI: 83, 91) of patients. In-hospital mortality was 41% (95%CI: 35, 46). Conclusions: PCP is a life-threatening disease in immune-compromised patients. Despite being a nonspecific clinical finding, GGO might offer a clue to diagnosing PCP in high-risk patients.
