Rash, Heart Failure, Renal Insufficiency, and Hypereosinophilia in an Elderly Frail Male

This patient was an elderly male with poor basal multi-organ function reserve, increased eosinophils leading to acute exacerbation of chronic heart and kidney dysfunction. After treatment with hormones and immunosuppressants, eosinophils were normal and the rash subsided. However, pneumocystis carinii pneumonia appeared in the later stage, and the anti-infective treatment was not ideal. Eventually the patient died of septic shock. In this case, the basic situation of the patient was complex, the diagnosis and treatment process was twists and turns, and the multidisciplinary team participated in and discussed to solve the problems in thediagnosis and treatment decision-making of the patient step by step, which embodied the significance of multidisciplinary cooperation in the diagnosis and treatment of difficult diseases.Based on the poor prognosis of the disease, it should be recognized clinically that weakness and delirium are also risk factors for poor prognosis in elderly patients. The elderly have weak compensatory ability, poor tolerance to adverse reactions, and are prone to adverse outcomes.In clinical diagnosis and treatment, the choice of plan needs to be considered in consideration of various factors such as treatment complications, long-term benefits, and expected survival time.
