Liver transplant recipients have a lower immune system than the general population due to the long-term use of immunosuppressive drugs and are more prone to “colds”. What should a liver transplant recipient do if he/she has a cold? Liver transplant recipients often have two attitudes, one is that they think it is not a big deal and do not consult a doctor in time, and follow their own life experience, drink more water and take some cold medicine by themselves; the other is that they are nervous and panic, worrying about the effect of cold medicine on liver function, and dare not take any medicine. In fact, for the cold after liver transplantation, we should pay attention to but not worry too much, we should give priority to prevention, timely treatment, proper regulation of immune status and reasonable use of drugs. Liver transplant recipients should pay attention to the prevention of colds. Increase and decrease clothes at any time when the climate changes from hot to cold, avoid cold and rain, overexertion, and avoid mental tension and worries. Wash your hands and change your toothbrush frequently. Massage in the morning and in the evening, often gently rub your finger to the root of your nose, pressing up and down 19 times each time or until you feel slightly hot. Rub your ears with hot water. Every night when you wash your face, rub your ears with a hot towel and gently rub your ears up and down 40 times. Wash your face with cold water and feet with hot water. During the flu period, avoid going to crowded public places with poor ventilation, and pay attention to daily ventilation in the living room, preferably in the early morning. Liver transplant recipients who have frequent colds should pay attention to their immune status and individualize the use of immunosuppressants under the guidance of their physicians. Since the immunity of each individual varies, the concentration of immunosuppressants required by each liver transplant recipient is different. Therefore, long-term follow-up is needed to regularly monitor the concentration of immunosuppressants, immune function and liver function, and to select the appropriate immunosuppressant use regimen from the changes in these three patterns. The rejection reaction after liver transplantation is mainly based on T-cell immunity, so CD4+ T-cell immune function testing can be a good guide to individualize the use of immunosuppressive drugs after liver transplantation. After liver transplant recipients have a cold, they should promptly seek medical consultation and take medication under the guidance of a doctor. Colds can be considered as an alarm bell for the immune status of the organism, especially recurrent colds. At this time, the immune status of the body should be monitored, and if the immunity is low, the dosage of immunosuppressants should be adjusted downward in time, and if available, it is recommended to take Bailing capsules or Cordyceps, which has a two-way immunomodulatory effect. After liver transplant recipient has a cold, the infection is easy to progressively aggravate and can develop into severe pneumonia in serious cases, so changes in infection symptoms should be noted, especially nasal discharge and sputum. When yellow-purulent nasal discharge or sputum appears, it indicates combined bacterial infection, and simple cold medicine only relieves cold symptoms such as nasal congestion, sneezing, runny nose, fever and headache, and cannot resist bacterial infection, and antibacterial drugs should be used at this time. The combined use of Mucosolvan can promote the excretion of phlegm, increase the concentration of antibacterial drugs in the respiratory tract and enhance the anti-infective effect, and Genoton has a good effect on expectoration and has a certain anti-infective effect. Liver transplant recipients should pay attention to diet regulation during cold. Drinking chicken soup can suppress the inflammation of throat and respiratory tract, which is extremely effective in eliminating the symptoms of nasal congestion, runny nose, cough and sore throat caused by cold. Because chicken contains a variety of amino acids necessary for the human body, rich in nutrients, can significantly enhance the body’s resistance to the cold virus, chicken also contains a special chemical substances, with enhanced blood circulation in the throat and the role of nasal fluid secretion, which protects the respiratory tract, clear the respiratory virus, accelerate the healing of the cold has a good role. Eat more radish and less salt, and keep the daily salt intake within 5 grams. Take honey. Eat more spices, ginger, dry chili, garlic help the body expel cold virus, cough and phlegm, can make the cold heal early. The selection of cold medicine should be based on specific symptoms. Be careful to use only one, should not repeat the drug, otherwise it can cause damage to liver and kidney function. At the beginning of cold, nasal congestion, dry throat, runny nose, sneezing and watery eyes (clinically known as khat symptoms), you can use compound pseudoephedrine extended-release capsule (Neocontrol). For chills, fever, initial headache with generalized muscle and joint pain, aspirin, acetaminophen, ibuprofen, fenpropathrin, taurine, etc., compound preparations such as compound acetaminophen tablets can be used. Cold symptoms are more severe, fever, headache, runny nose, sneezing, nasal congestion, sore throat, cough, sputum, etc., you can use compound anti-cold drugs containing pseudoephedrine, chlorpheniramine maleate, diphenhydramine, artificial taurine, dextromethorphan, etc. When applying anti-cold drugs containing pseudoephedrine, elderly people, patients with heart disease, hypertension, hyperthyroidism, glaucoma and prostate hypertrophy should use them with caution.
