Lupus erythematosus generally refers to systemic lupus erythematosus (SLE), which is mostly related to environmental, genetic, immune and other factors, and the disease is generally not curable. SLE is a systemic autoimmune disease that can involve multiple organs and systems. The clinical manifestations of patients are diverse. Although medications and other treatments can be used to control the progression of SLE patients, there is currently no effective cure for the disease, and the treatment is more complex than that for other diseases. Commonly used medications for SLE include hydroxychloroquine, non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, and immunosuppressants such as mertiomacrophenol ester, etc. With the advancement of medical science, the survival rate of patients with SLE has improved significantly compared to that of the previous period, but without timely and standardized treatments, the disease may involve organs such as the heart, lungs, and brain, which can be life-threatening in severe cases. SLE patients are advised to go to the rheumatology and immunology departments of regular hospitals for detailed consultation and standardized diagnosis and treatment according to doctors’ instructions.
