There is no effective vaccine to prevent hepatitis C. Therefore, for hepatitis C, one is to carry out scientific prevention, and the other is to carry out timely and correct treatment. First, how to prevent hepatitis C In recent years at home and abroad in the prevention of hepatitis C accumulated a lot of mature and effective experience, as long as the following factors are controlled, most of the hepatitis C can be avoided. 1. Strict screening of blood donors: The Blood Donation Law of the People’s Republic of China should be strictly enforced to promote blood donation without compensation. By testing serum hepatitis C antibodies, transaminases strict screening of blood donors, some countries are now also beginning to test HCV antigen and nucleic acid, so that the window period of infection can also be detected, a higher degree of blood safety. As a public, we just need to pay attention to the use of blood and blood products from the regular way can be. In addition, it should be noted that the indications for blood and blood products (whole blood, blood cells, plasma, clotting factors, albumin, immunoglobulins) must be strictly controlled and not used if possible. 2. Prevention of transdermal and mucosal route of transmission: Be sure to go to regular, strictly sterilized medical institutions to receive dental procedures, endoscopy, cosmetic surgery, intramuscular and intravenous injections. Intravenous drug users should be actively detoxified, and must not share syringes. Do not share razors, dental instruments, acupuncture needles, etc. in your life. Haircutting utensils, piercing and tattooing utensils should also be strictly disinfected. 3, the prevention of sexual transmission: people with a history of sexual promiscuity should self-restrain and regular checkups, and it is recommended that HCV-infected people use condoms during sexual intercourse, not only to protect others but also to protect themselves. 4, prevention of mother-to-child transmission: for pregnant women with positive hepatitis C nucleic acid, they should go to a regular and experienced hospital for delivery, should avoid amniocentesis, try to shorten the delivery time, ensure the integrity of the placenta, and reduce the chance of exposing the newborn to maternal blood. 5. Patients on long-term dialysis should be regularly checked for hepatitis C and minimize blood contact with other patients. How to treat Once the diagnosis of hepatitis C is confirmed, it is necessary to carry out timely and standardized treatment, the main measures and methods are: 1, interferon and ribavirin antiviral therapy: this is currently the main means of hepatitis C treatment. The purpose of antiviral therapy is to remove or continuously inhibit the replication of the virus in the body in order to improve or reduce liver damage, stop the progression to cirrhosis, liver failure or liver cancer, and improve the quality of life of patients. Currently, the main antiviral drugs are interferon and ribavirin, both in China and abroad. Interferon is available as regular interferon and long-acting interferon. The ordinary interferon is usually injected once every other day, 3-5 million units each time, and the course of treatment is about one year, which is relatively cheap. Long-acting interferon, also known as pegylated interferon, has a long half-life and is metabolized slowly in the body. The combination of interferon and ribavirin is currently the most effective antiviral treatment regimen and is superior to interferon alone. Long-acting interferon injected subcutaneously once a week combined with ribavirin taken orally for 48 weeks has a sustained viral nucleic acid regression rate of 54% to 60%; ordinary interferon injected intramuscularly three times a week combined with ribavirin for 48 weeks has a nucleic acid regression rate of 44% to 47%. Ribavirin is inexpensive and should be used in conjunction with interferon if there are no contraindications. Interferon has a number of adverse reactions, including early fever, anorexia, leukopenia, and malaise, flu-like symptoms, and depression during the course of application. Ribavirin also has adverse effects such as nausea and anemia. Therefore, antiviral treatment or not, how to treat, how to monitor the efficacy and adverse reactions, how to adjust the treatment plan and other issues need to be under the guidance of an experienced specialist. 2, other antiviral treatment: many patients already have cirrhosis and leukocyte and platelet reduction, and cannot tolerate the side effects of interferon and ribavirin. At this time, you can try to apply bitter ginseng and thymidine and other treatments. Some patients who are not expected to respond well to antiviral therapy before treatment (such as some viral subtypes of infection) can be treated with plasma virus filtration, a new technique from Japan, which is based on the principle of rapidly filtering out excess hepatitis C virus from plasma through extracorporeal blood circulation like dialysis, and then applying antiviral therapy such as interferon, the effect will be improved. It has been included in the medical insurance of Japan. 3, liver protection and lower enzymes and other comprehensive treatment: alcohol will accelerate the development of the disease and reduce the effectiveness of antiviral drugs, so you should first stop drinking. Exertion is not conducive to the return of liver function, too tired can occasionally cause heavy hepatitis and liver failure, so patients with hepatitis C should properly control the intensity of physical activity, but if the liver function is basically normal, you can generally go to work. If the transaminases are abnormal, it is recommended to give infusion or oral hepatoprotective drug therapy, which are more available, including silymarin, dicyclomine, etc. 4.Nutritional support treatment: If the patient is thin, gray and malnourished, he needs to gradually improve his mental state and eat some high protein and high vitamin diet such as milk and broth. If cirrhosis is obvious and albumin is declining, you can take oral Nuova and other compound liver nutrition preparations, which can increase the plasma albumin level and improve the nutritional status of the patient’s whole body, and some patients’ complexion can be improved after long-term application. 5, other: individual patients with hepatitis C will develop into advanced cirrhosis, if particularly serious can be considered for liver transplantation. Individual patients with co-infection of HIV, and the treatment of HCV-infected patients who are on dialysis, have corresponding treatment plans. 6, regular follow-up: whether treated or untreated hepatitis C patients, should regularly review liver function, viral nucleic acid, methemoglobin, ultrasound, especially for those who have been infected for more than 10 years or are over 40 years old, generally try to review once every six months. In conclusion, hepatitis C is preventable and treatable, and as long as you understand the above methods, most hepatitis C can be prevented, or well controlled.
