The early characteristic rash of lupus erythematosus is typically a butterfly-shaped rash on the face. Other common presentations include palm and periungual erythema, discoid rash, nodular erythema, and livedo reticularis. If the rash is not notably itchy, it generally indicates lupus erythematosus. If there is significant itching, it may suggest the possibility of an allergic factor active in the disease. After immunosuppression, itchy rashes should be monitored for possible fungal infections. The specific pathogenesis of systemic lupus erythematosus is still unclear. If a patient exhibits the typical butterfly-shaped rash on the face, systemic lupus erythematosus should be highly suspected. Testing for antinuclear antibodies, and specifically for anti-Sm and double-stranded DNA antibodies, which represent a variety of autoantibodies, can diagnose systemic lupus erythematosus.

What happens if someone with lupus occasionally drinks alcohol?

Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple systems and organs throughout the body and is more commonly seen in women, particularly during their childbearing years. Clinically, it is mainly characterized by fever, rash, joint pain, oral ulcers, and hair loss. In terms of diet, it is recommended to eat light and avoid spicy and irritating foods. It is crucial to strictly abstain from smoking and drinking, avoid excessive fatigue, and direct sun exposure. Importantly, patients should strictly follow medical advice regarding medication and have regular check-ups.

Will the rash of lupus fade away?

Patients with lupus often experience recurrent, stubborn skin lesions on their hands or face, and some may even develop ulceration, atrophy, or scarring on top of the existing erythema. Most lupus patients exhibit erythema, centered around the bridge of the nose and appearing on the cheeks. The lesions are disc-like on both sides with generally clear boundaries, either flat or slightly raised, and are categorized as exudative inflammation. Depending on the severity of the inflammation, the erythema can range from light red, bright red to purple-red. In severe cases, localized edema resembling erysipelas may occur, and scaling and hyperpigmentation may appear as the inflammation subsides. Facial rashes generally resolve, and most rashes do not leave marks after resolution. If hyperpigmentation remains after the erythema has resolved, it suggests a good prognosis. However, erythema in other areas, such as acral erythema and reticular cyanosis, may last for varying durations depending on the patient's individual condition.

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.

Where does lupus erythematosus generally appear?

Lupus erythematosus can appear on various parts of the body. The most typical rash is the butterfly rash on the face, but it can also appear on other parts, such as discoid lupus, annular erythema, periungual erythema, and livedo reticularis. Additionally, systemic lupus erythematosus affects not only the skin and mucosa but can also involve the lungs, kidneys, heart, central nervous system, and other systems. Common manifestations include lupus nephritis and lupus pneumonia. The precise pathogenesis of systemic lupus erythematosus is still unclear. If the damage is confined to the skin and mucosa, immunomodulators such as hydroxychloroquine can be used for treatment. If important organs are involved, it generally requires long-term maintenance treatment with corticosteroids combined with immunosuppressants to control the progression of the disease.
