The patient was admitted to the clinic due to anorexia and grease, after examination the patient’s liver function transaminases were significantly increased, suggesting hepatocellular damage, and the examination found that the patient had chronic viral hepatitis B, and the quantification of hepatitis B DNA was 6×10^6IU/ml. after hospitalization, the patient was given the symptomatic treatments of antiviral treatment with entecavir capsules and hepatoprotective treatment with diammonium glycyrrhizinate enteric-coated capsule, and the patient’s transaminases were reduced to normal, and the patient was discharged from the clinic with symptomatic improvement. Basic information] Male, 45 years old [Type of disease] Chronic viral hepatitis B [Hospital] Liaocheng City People’s Hospital [Time of consultation] November 2021 [Treatment plan] Medication (entecavir capsule + diammonium glycyrrhizinate enteric-coated capsule) [Cycle of treatment] Hospitalization for 2 weeks, outpatient review after 2 weeks [Effect of treatment] Improvement in liver function, anorexia is less severe, and the diet is improved. The patient had a dark yellow color at the time of consultation, and was reluctant to eat greasy food for more than a month, and nausea easily appeared when seeing greasy food, accompanied by symptoms such as fatigue, distension and pain in the right epigastric region, etc. The routine blood test and liver function test found that there was a significant increase in the transaminases of the liver, and when asked for the history of the patient, the patient did not have any cases of large amount of alcohol consumption, oral medication or exposure to poison, etc. The hepatitis B virus screening test found that the patient was suffering from chronic hepatitis B, and the DNA test of the patient was checked. Hepatitis B virus screening found that the patient had chronic viral hepatitis B. Hepatitis B DNA quantification found that the result was 6×10^6IU/ml, and the patient was admitted to the hospital with the first consideration of hepatic impairment caused by chronic viral hepatitis B in active stage. Second, the treatment process The patient is currently presenting with liver function impairment and hepatocellular damage, and the main task is to identify the causes of liver function impairment, common alcohol consumption and drugs, which can already be ruled out when pursuing the patient’s medical history. At present, the patient has chronic viral hepatitis B, but autoimmune liver disease needs to be excluded, the patient checked the relevant autoimmune liver disease related indicators were found to be negative, the patient should be diagnosed as chronic viral hepatitis B. The patient is currently in the active stage of hepatitis. Currently belongs to the active stage of hepatitis, the main treatment is antiviral, liver protection therapy. The treatment program is entecavir capsule anti-hepatitis B virus, diammonium glycyrrhizinate enteric capsule to protect the liver and other symptomatic treatment, treatment for about 10 days, the patient’s symptoms have improved significantly. In the 3rd day after the treatment, the patient was rechecked for liver function, and the aminotransferase decreased significantly, and the patient’s symptoms of anorexia and fatigue were relieved, and the amount of food was increased gradually. Hepatitis B DNA quantification was rechecked 1 week after treatment, and it had decreased significantly, indicating that the patient’s chronic viral hepatitis B treatment was effective. With the progress of the treatment, when hospitalized for 2 weeks, the patient’s diet returned to normal, and the general condition gradually improved, and the patient was allowed to be discharged, and the patient was instructed to continue to go home and take oral medication according to this plan after discharge, and to be rechecked after 2 weeks. Fourth, precautions I am glad that after treatment, the patient’s liver function improved, anorexia symptoms reduced, diet can be improved, it is recommended that the patient is discharged from the hospital to pay attention to the following points: 1, usually quit smoking, alcohol, diet should pay attention to the light diet, avoid spicy, stimulating, greasy food, and at the same time, to increase the nutrition, and more intake of high-protein foods, such as lean meats, eggs, milk, fish, shrimp, etc., and more fresh fruits and vegetables, in order to supplement sufficient vitamins; 2, to add vitamins; 2, to add vitamins to the patient’s diet. Patients should go to outpatient clinic for review after 2 weeks to check whether liver function is back to normal, and then check whether hepatitis B DNA quantitative continues to decline, if hepatitis B DNA quantitative continues to decline, you can continue to take oral entecavir capsule treatment, if the decline is not obvious, it is also possible that the virus is not sensitive to this drug, and it may be necessary to change the other antiviral drug treatment; 3, when hepatitis B DNA quantitative and liver function drop to normal, it is necessary to increase nutrition. After the DNA quantification and liver function are reduced to normal, it is necessary to review the relevant hepatitis indicators once every six months. The most common hepatitis is chronic viral hepatitis B, and many patients often do not know that they are hepatitis B patients or hepatitis B carriers. And hepatitis is contagious, it is recommended that if there is a family history of hepatitis, or related immediate family members, should do routine hepatitis examination. At the same time, if the diagnosis of hepatitis B patients, anorexia greasy food, nausea, abdominal pain and other symptoms, you need to consult a doctor in time, may be the active stage of hepatitis or even hepatitis B caused by other lesions. In this case, the patient came to the hospital for examination because of symptoms such as anorexia and greasiness, and was found to have chronic viral hepatitis B. After regular treatment, the disease was brought under control.
