The duration of itching in the early stages of lupus erythematosus is not fixed.

It is not certain that early-stage lupus erythematosus will cause itching. Some patients may experience itching, which can subside on its own, but it tends to recur. Additionally, some patients may have itching due to allergies, which can result in rashes accompanied by itching. It is possible to check immunoglobulin E to see if there are any allergic factors present.

If allergies are involved, treatment can include antihistamines or corticosteroids, or topical calamine lotion can be used to relieve symptoms.

Besides affecting the skin, early-stage lupus erythematosus can also cause symptoms such as oral ulcers and arthritis in many patients.

Can people with lupus eat beef?

For patients with lupus, we recommend eating less beef. This is because our dietary guidelines for lupus patients are: high protein, low fat, low salt, low sugar, and foods rich in various vitamins and calcium. Since beef is a high-phenylamine protein food, it is advised to consume less of it. Patients can eat some fish, lean meat, chicken, and duck, depending on their financial situation, to supplement the protein lost in the kidneys but should not eat too much to avoid indigestion. The diet for lupus patients should be light, and when cooking, food should not be too oily or too spicy.

What should I do if I have a fever with lupus erythematosus?

When patients with lupus experience fever, the fundamental approach is the use of ample steroids or other immunosuppressive drugs for treatment, which generally can quickly normalize body temperature. However, some patients may also experience fever during steroid use, possibly due to the steroids reducing immune function and inducing a bacterial infection. At this point, it is necessary to find evidence of infection and promptly treat with adequate sensitive antibiotics. Then, there will certainly be questions about why patients with lupus who have a fever cannot use antibacterial drugs or antipyretics. This is because fever in lupus patients is often an important indicator of disease activity. During acute phases, the fever is typically high, not caused by external infections, thus antibacterial drugs are ineffective. Using antipyretics can temporarily normalize body temperature, but once the effect of the medication wears off, the high fever may recur. Patients with lupus should not casually use medications. If medication is needed, it should be used under the guidance of a doctor.

What should I do about lupus erythematosus?

Lupus erythematosus requires early and formal treatment to stabilize the condition. For mild cutaneous lupus erythematosus, topical immunosuppressants, such as tacrolimus ointment, and immunomodulators, such as hydroxychloroquine, can be used. Low-dose corticosteroids may be necessary for combination therapy. Systemic lupus erythematosus generally requires corticosteroids as the basis of treatment, combined with one or several immunosuppressants to effectively control the disease. Systemic lupus erythematosus often involves multiple organs, with the kidneys, hematological system, and lungs being the most common. Therefore, it is necessary to use corticosteroids in combination with immunosuppressants to control the progression of the disease, as using only immunomodulators is often insufficient.

What are the symptoms of the early stage of lupus erythematosus?

The main symptom in the early stage of lupus is the appearance of a butterfly-shaped rash on the face, with most patients initially exhibiting these rashes, some of which are not butterfly-shaped. The rash can also appear on fingers, palms, and around the nails. Additionally, over 80% of patients experience unexplained fevers, which are irregular and can sometimes reach up to 40 degrees Celsius. Some patients also experience joint pain in the early stages of the disease, mainly starting with pain in larger joints such as the elbows, knees, and ankles. If joint pain is accompanied by fever, rash, and a decrease in white blood cells, it is advisable to promptly visit a hospital for an examination to check for lupus. Some patients may also experience Raynaud's phenomenon and photosensitivity in the early stages of lupus. There are no fixed symptoms in the early stages of lupus; it is mainly important to observe oneself regularly and seek medical attention if feeling unwell.

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.
