Background: Respiratory syncytial virus (RSV) is a single-stranded RNA virus that commonly causes symptoms of upper respiratory tract infections in humans, with a clear seasonal trend. However, in immunocompromised and elderly patients, RSV infections still result in high rates of hospitalization and even risk of death.
Methods: We report a case of RSV infection in an adult with immunodeficiency, which initially showed only mild symptoms of upper respiratory tract infection, which did not improve after receiving empirical anti-infective treatment, and the foci of infection in the lungs continued to expand, which led to the aggravation of the disease. The diagnosis of RSV infection was finally confirmed by electron bronchoscopy and pathogenetic examination of the bronchoalveolar lavage fluid. The patient was given intravenous ribavirin treatment for one week. After one week of intravenous ribavirin treatment, the patient's symptoms improved significantly. A repeat chest CT suggested that the lung lesions were smaller than before. In order to improve clinicians' awareness of this disease, we jointly conducted a literature analysis.
Results: The final diagnosis of RSV was made by analyzing the patient's history, symptoms, and signs and performing relevant examinations.
Conclusions: For patients with poor results of empirical application of antibiotics, electronic bronchoscopy and pathogenetic examination should be carried out at an early stage to clarify the nature of the lesions and to avoid rapid deterioration of the condition leading to life-threatening conditions in the patients. More consideration should be given to the possibility of disease diagnosis to avoid misdiagnosis and underdiagnosis, and appropriate treatment should be given at an early stage.
