Case Report: Complete Remission of a Patient with Acute-on-chronic Liver Failure with Rare Hepatic Encephalopathy and Fever of Unknown Origin Treated with Anti-infective Therapy Combined with Psychotherapy After Artificial Liver Support System

The theme of this report is incredible psychological therapy's inspiration for fever of unknown origin (FUO). We analyzed this incredible phenomenon through psychological immunity, liver immunity, inflammation, etiology, diagnostic methods, and treatment strategies. A man, 44 years old, was dyed for more than 40 days due to abdominal distension with skin and scleral yellow, and feathers accompanied him for four days to enter the hospital. Hepatitis virus test shows HBV infection. HBV DNA detection shows negative. The detection of the respiratory tract nine-fold, tuberculosis, anemia, and gut-to-club ratio all show negative. Due to the weakness of the patient's body, we cannot cooperate with more examinations. We use blood specimens to monitor and analyze for 25 days. In short, this is a case of chronic-acute liver failure, manic, and fever, likely to be an FUO cause in terms of the treatment plan, general treatment, artificial liver treatment, surgical treatment, anti-infection therapy, and psychotherapy. The patient reached the common treatment goal after 25 days of treatment. This report aims to provide psychotherapy programs and clinical characteristics for patients with chronic-acute liver failure, manic, and FUO and provide inspirational thinking strategies for long-term blood specimen examination. The potential mechanism of psychological fever is immune disorders, and the decline in the concentration of immunoglobulin A and E may be a direct factor.
