OBJECTIVE To explore the pathological characteristics and outcomes of elderly patients with community acquired pneumonia (CAP) accompanied by coronavirus disease 2019 (COVID-19). METHODS The diagnosis and treatment process of one elderly patient with CAP accompanied by COVID-19 who was admitted to COVID-19 Treatment Center of Liaoning Province on February 7, 2020 were reviewed. The experience of treatment by analyzing the characteristics of such type of patients during diagnosis and treatment were summarized. RESULTS A female patient, aged 79 years ald, was admitted to the Center with following features: fever, dry cough, fatigue with dyspnea, scattered moist rales in both lungs, oxygenation index (PaCO2/FiO2) of 95 mmHg (1 mmHg = 0.133 kPa), and diffuse interstitial pneumonia in both lungs indicated by chest CT, of which the majority were ground glass-like and fibrous lesions. It was confirmed to be consistent with the feature of severe COVID-19 cases. The patient was successfully cured one month later following anti-inflammatory, anti-viral and high-flow oxygen therapies, homeostasis maintenance of the body, psychological counseling, etc. Accordingly, the treatment experience in CAP combined with COVID-19 in the elderly patients was summarized as follows. In respiratory system, the timing of high-flow oxygen therapy and mechanical ventilation should be seized. As for anti-inflammatory and antiviral therapy, attention should be paid to the treatment of CAP as well as antiviral therapy and symptomatic and supportive therapy. With the progression of the disease, the production of drug-resistant bacteria and the possibility of fungal infection should be paid attention to. For the circulatory system, we should pay attention to the stability of fluid volume and internal environment, and strengthen hemodynamic monitoring and bedside ultrasound to evaluate the cardiovascular capacity-load. In the aspect of the immune system, the selection of the application time of immune-enhancers and glucocorticoids should be paid attention to. In terms of enteral nutrition, early low-fat and high-protein diet is conducive to the recovery of intestinal function and the prevention of bacterial translocation. In addition to the protection of the function of important organs, therapies such as reasonable sedation and psychological intervention should also be used. CONCLUSIONS Elderly patients with CAP accompanied by COVID-19 have complicated conditions and high degree of difficulty in treatment. Comprehensive evaluation of the disease as well as synthetic and effective intervention are the key factors of successful treatment of such patients.
