When patients with lupus erythematosus experience a cold and cough, we should first conduct a routine blood test to see if it is caused by an infection, and then treat the symptoms accordingly. If the patient has a cough with phlegm, we should first help the patient clear the phlegm to avoid choking. Patients with lupus erythematosus should not take medication at will. If medication is needed to treat the cold and cough, it should be used under the guidance of a doctor.

What causes lupus erythematosus?

The cause of lupus erythematosus is not yet very clear. It is generally believed that the disease is caused by a combination of factors including genetics, environment, estrogen levels, and drugs, leading to immune disorder and consequently the onset of this disease. Studies have found that factors directly related to the onset of lupus erythematosus include ultraviolet rays causing apoptosis of epidermal cells, exposure of new antigens becoming autoantigens, and infections; Other possible related factors include drugs such as hydralazine and isoniazid, as well as food dyes, hair dyes, celery, figs, mushrooms, smoked foods, psychological stress, etc.; it may also be related to factors such as tobacco, vinyl chloride, asbestos, and vaccinations.

Is lupus contagious?

Lupus erythematosus is not contagious. The occurrence of lupus erythematosus is related to genetic factors, the levels of sex hormones in the body, and certain environmental factors that the body is exposed to. It is the combined effect of these factors that lowers the body's immune tolerance, causing disorder in immune function, and thus leading to this autoimmune disease. Therefore, unlike diseases caused by various pathogens, it cannot be transmitted from person to person. When normal individuals come into contact with patients, there is no need to fear contagion or to isolate the patients. During the remission and stable phases of the disease, lupus patients can engage in regular work, study, and participate in social activities just like healthy individuals.

What foods are good for lupus erythematosus?

The diet for patients with lupus erythematosus varies from person to person. Generally, the ideal food for lupus patients should have the following characteristics: an appropriate amount of high-quality protein, low fat, low salt, low sugar, and rich in vitamins and calcium. Since many lupus patients often have significant kidney damage, proteins are frequently lost in large amounts through the urine, causing hypoalbuminemia and edema. The supplementation of protein should primarily consist of high-quality animal proteins, such as milk, eggs, and lean meats. However, protein intake should also be appropriate and not excessive. Excessive intake can not only lead to incomplete absorption by the patient, increasing the burden on the gastrointestinal tract, but also increase the excretion of nitrogenous compounds in the body, further burdening the kidneys. Lupus patients should avoid or minimize consumption of foods that can enhance photosensitivity, such as figs, rapeseed, cilantro, and celery. If consumed, they should avoid sun exposure afterwards. Mushrooms, smoked foods, and certain food dyes can also trigger lupus and should be avoided or minimized in the diet.

Can lupus patients get pregnant?

Patients with lupus can conceive normally, but it is not recommended to become pregnant. This is because patients with lupus who become pregnant are prone to miscarriage, preterm birth, stillbirth, and poor fetal development in the uterus, especially in patients who are positive for antiphospholipid antibodies. Pregnancy can also aggravate the disease or cause a relapse in lupus patients, and even if the disease is stable, there are cases where the condition worsens during pregnancy or after childbirth. Therefore, it is not recommended for patients with active systemic lupus erythematosus to become pregnant. If the condition has been stable for more than a year after treatment and the patient has been off medication for at least 6 months, then pregnancy can be considered. However, it is important to note that dexamethasone, immunosuppressants, and Tripterygium wilfordii tablets have side effects on the fetus and should be avoided.

Do the rashes caused by lupus itch?

The erythema triggered by lupus erythematosus may or may not be itchy, varying from person to person, with each individual's condition not being entirely the same. The erythema caused by systemic lupus erythematosus also presents very differently clinically, with the typical manifestation being a butterfly-shaped erythema on the face. Other common forms include discoid erythema, reticular purpura, polymorphic rash, periungual erythema, and more. The specific pathogenic mechanism is currently unclear, and in some patients, the condition is caused by photosensitivity. After treatment, the erythema cannot completely disappear in a significant number of patients, leaving some pigment deposition. If only the skin is affected, treatment can involve the topical use of tacrolimus ointment or the oral intake of immunomodulators like hydroxychloroquine, and if necessary, oral corticosteroids may be administered.
