Systemic Lupus Erythematous (SLE) is a chronic autoimmune disease which causes the immune system to mistakenly attack health body tissue. In SLE, body immune system can affect any part of the body, such as joints, organs, eyes, skin, etc. Often SLE can result in symptoms such as malar rash, discoid lesions, sub-acute cutaneous lesions, photosensitivity, oral ulcers, arthritis, serositis, nephropathy, neurologic involvement, thrombocytopenia, haemolytic anemia, fever, Raynaud's phenomenon, livedo reticularis, thrombosis, and myositis. It is also known as a disease of flare-ups and remissions and can range from mild to life threatening severity. It is also called as drug-induced lupus erythematosus due to common observation against drugs such as isoniazid, hydralazine and procainamide. Currently, there is no complete treatment for SLE. While only two biologic agents have been approved by FDA to treat SLE, synthetic drugs are still the mainstay of therapy in SLE. Based on available evidence, azathioprine and mycophenolate mofetil are the drugs of first choice. Hydroxychloroquine should be considered an anchor drug in SLE because of the multiple beneficial effects of this agent.
