Introduction
A high anti-dsDNA result indicates that the patient has systemic lupus erythematosus (SLE), a common autoimmune rheumatic disease that can affect multiple organs and systems throughout the body. Without timely treatment, it may significantly impact the nervous system and skin, and in severe cases, it can be life-threatening. During treatment, patients should keep warm, maintain a balance between rest and activity, and avoid exposure to direct sunlight.

Anti-ds-DNA usually refers to anti-double-stranded DNA. Elevated levels suggest a possible autoimmune disease, such as systemic lupus erythematosus (SLE), but a definitive diagnosis should be made in combination with clinical symptoms and other test results.

Anti-double-stranded DNA antibodies are primarily associated with systemic lupus erythematosus, a common rheumatic autoimmune disease that can affect multiple organs and systems throughout the body. Common clinical manifestations include fever, rashes, joint pain, recurrent oral ulcers, hair loss, and nephritis. The disease may also involve the lungs, presenting as interstitial pneumonia or serositis, and requires long-term maintenance treatment along with regular follow-up examinations. If elevated anti-double-stranded DNA levels are detected, it is recommended to complete additional tests, including complete blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), urinalysis, immunoglobulins, and complement levels.

In clinical practice, several methods are available for detecting anti-double-stranded DNA antibodies, among which indirect immunofluorescence is commonly used. If antibody levels are elevated and typical multi-organ involvement is present, along with supporting laboratory findings, medication is needed to control systemic lupus erythematosus. Patients are typically treated under medical guidance with drugs such as methylprednisolone tablets, azathioprine tablets, and cyclophosphamide for injection. Without timely treatment, the disease may severely affect the nervous system and skin, potentially endangering the patient's life. During treatment, patients should stay warm, maintain a balance between rest and activity, and avoid exposure to direct sunlight.

In daily life, maintaining a healthy lifestyle—including a light diet and regular作息—can support recovery.
