Clinical characteristics of patients with acquired immunodeficiency syndrome having respiratory symptoms as the initial manifestations: A retrospective study

Abstract

The aim of the study was to investigate clinical features of patients with AIDS having respiratory symptoms as initial manifestations and help in the early diagnosis. Eighty-eight patients admitted to the Shanghai Pulmonary Hospital were included in the study. General data, clinical manifestations, laboratory tests, chest computed tomography (CT) imaging features, treatments, and prognosis were analyzed. Peripheral leukopenia, lymphopenia, hypoxemia, and reduced percentage of CD4+ T lymphocytes were found in 25.6%, 43.6%, 27.5%, and 94.9% of the patients, respectively. Pneumocystis jirovecii pneumonia (PCP) was the most frequent cause of opportunistic pulmonary infection. Patients with PCP had more bilateral lung involvement and ground-glass shadow in CT manifestations. A follow-up of the 43 patients transferred to the Public Health Center showed improvement in 27 (62.8%), stabilization in 4 (9.3%), worsening in 1 (2.3%), and death in 11 (25.6%) patients. Detailed medical history recording, screening of human immunodeficiency virus antibody, and flow cytometry would improve the diagnostic efficiency of AIDS in patients with diffuse ground-glass shadow in chest CT. Early and empirical treatment could improve the prognosis.
