The most typical skin rashes of systemic lupus erythematosus are called butterfly rash and discoid rash. The so-called butterfly rash is a rash on both sides of the nostrils, resembling the wings of a butterfly, and the so-called discoid rash is a circular, disc-shaped rash on the facial area. At the same time, patients with systemic lupus erythematosus may also experience reticular purpura or vasculitic rashes like those of end-finger vasculitis, all of which are typical manifestations of skin rashes in patients with systemic lupus erythematosus.

Systemic lupus erythematosus is not contagious.

Firstly, systemic lupus erythematosus is an autoimmune disease with an unclear cause. It can affect multiple organs including the heart, lungs, and kidneys. It is classified as an autoimmune disease and not a contagious one, so there is no need to worry about it spreading. However, this condition does have a certain genetic predisposition. For instance, if parents have systemic lupus erythematosus, then their offspring have a relatively higher chance of developing the condition compared to families without a history of the disease. Being an autoimmune disease, it cannot be cured but can only be managed with medications such as corticosteroids to control the progression of the disease. Therefore, during the course of steroid treatment, it is vital to prevent infections. Finally, it is important to emphasize once again that systemic lupus erythematosus is not contagious and does not pose a risk of transmission, so everyone can be reassured.

Can people with systemic lupus erythematosus eat black fungus?

Systemic lupus erythematosus is an autoimmune disease that affects multiple systems and organs. It cannot be cured and can only be managed through medications to control the progression of the disease and delay complications. It commonly occurs in women of childbearing age. In the early stages, when no other organs are damaged, there are no special dietary restrictions and black fungus can be eaten. However, fruits such as figs and bayberries, which are exposed to ultraviolet light for a long period, should be avoided. If the disease affects the kidneys causing damage such as proteinuria and increased creatinine, a diet low in salt, fat, and restricted in high-quality protein is necessary. High-quality protein mainly refers to lean meats and pure milk, and consumption of black fungus should be moderated.

Is systemic lupus erythematosus serious?

Firstly, whether systemic lupus erythematosus (SLE) is severe cannot be generalized. It is an autoimmune disease that cannot be completely cured and can cause damage to multiple systems and organs, leading to serious complications. Therefore, it is crucial to conduct a clinical analysis and assess the severity of the condition as mild, moderate, or severe after diagnosis. Furthermore, if severe anemia or a decrease in platelets occurs, the condition is relatively severe, and the presence of oliguria or anuria or central nervous system damage, this is known as lupus crisis. These conditions can be life-threatening, even leading to death. In such cases, the condition is relatively critical, and it is essential to actively treat and control the condition. Once the condition stabilizes, the medication dosage should be gradually reduced to maintain stability.

Systemic Lupus Erythematosus Test Items

First, if there are symptoms such as facial erythema, butterfly rash, joint pain, hair loss, or even stillbirth or miscarriage, systemic lupus erythematosus should be suspected. For systemic lupus erythematosus, related medical tests are necessary, including complete blood count, urinalysis, erythrocyte sedimentation rate, C-reactive protein, 13 autoantibody tests, and anticardiolipin antibodies. These are the primary and most basic tests, specifically the 13 autoantibody tests. If the diagnosis is confirmed based on these tests, further assessments such as heart evaluation, chest CT need to be perfected. When necessary, 24-hour urine protein quantitation and kidney biopsy should be performed to assess the damage to the kidneys and the severity of the condition, mainly influencing the subsequent treatment plan.

Can systemic lupus erythematosus become pregnant?

Firstly, systemic lupus erythematosus is a multisystemic, systemic autoimmune disease that can involve multiple organs throughout the body. Regarding the issue of whether one with systemic lupus erythematosus can become pregnant, it cannot be generalized and must be considered in conjunction with the condition of the disease. For example, if the disease is in its early stages and has been stabilized through treatment, then it is possible to become pregnant. If systemic lupus erythematosus has already presented with severe complications, such as lupus nephritis, significant proteinuria, or an increase in creatinine urea, affecting kidney function and causing kidney damage, then it is not recommended to become pregnant during this period. Pregnancy at this time not only offers no substantial benefit to the person with systemic lupus erythematosus but can also increase the burden on the kidneys, leading to further deterioration of kidney function, which can be life-threatening.
