In the early stages of lupus erythematosus, symptoms such as fever, rash, joint pain, oral ulcers, and hair loss may occur. Lupus erythematosus is a heterogeneous disease that can present a variety of clinical symptoms. This disease can affect multiple systems and organs throughout the body, leading to different clinical manifestations depending on the target organ involved. For example, patients with pulmonary interstitial fibrosis may experience chest tightness, shortness of breath, and difficulty breathing; if the heart is affected, significant pericardial effusion may occur, possibly leading to difficulty breathing. The specific pathogenesis of systemic lupus erythematosus is still unclear. It is more commonly seen in females. Therefore, there is currently no specific cure for systemic lupus erythematosus, and the treatment mainly involves long-term maintenance with corticosteroids and immunosuppressants.
