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 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.

Some patients experience kidney involvement, primarily presenting as significant proteinuria, hematuria, and cylindrical urine. Pulmonary involvement is also common in some patients, often manifesting as pleurisy. The digestive system can also be affected, typically presenting as abdominal pain. The hematological system is a very common site of involvement in lupus, mainly indicated by routine blood tests showing decreases in white blood cells and platelets.

Can people with systemic lupus erythematosus eat mutton?

Patients with systemic lupus erythematosus should not eat lamb. This is because foods like lamb and dog meat are overly warming and nourishing, and they may trigger a relapse of the disease. Patients should also consume less of the foods that are photosensitive, such as celery, coriander, and mushrooms. Moreover, since lupus is an autoimmune disease and patients tend to have hypersensitive constitutions, they should also reduce their intake of seafood such as shrimp and crab. Additionally, patients should avoid certain warming and nourishing foods like longan. At the same time, they can supplement their diet with high-quality, low-protein foods like egg whites and fish.

What should I do about hair loss from systemic lupus erythematosus?

First, systemic lupus erythematosus is an autoimmune disease characterized by multi-organ and multi-systemic damage, a systemic autoimmune disorder. It cannot be completely cured, but its symptoms can be managed and the progression of the disease can be controlled through medication. The main clinical manifestations include facial rashes, photosensitivity, Raynaud's phenomenon, fever, hair loss, etc. Therefore, in the treatment process of patients with systemic lupus erythematosus, if there is an increase in hair loss, or if other symptoms such as photosensitivity and hair loss occur, it may be considered that the disease is active or recurring. At this time, it is necessary to go to the hospital for comprehensive tests such as blood routine, erythrocyte sedimentation rate (ESR), complement levels, and autoimmune antibodies to assess the condition. If the disease is active or recurring, an adjustment in the dosage of the treatment medications may be necessary.

What causes systemic lupus erythematosus?

Firstly, systemic lupus erythematosus belongs to autoimmune diseases and is a multisystemic autoimmune disorder. It is a chronic disease that cannot be cured. It can only be managed through medication to control the progression of the disease, prevent relapses, delay damage to other organs, and prevent complications. This is the overall principle of treatment. Its cause is currently unclear. It is only related to factors such as environmental pollution, viral infections, genetics, and hormones, according to expert research. However, there is no specific definitive cause identified.
