Overview of
Systemic Lupus Erythematosus (SLE)Definition and Symptoms
Systemic Lupus Erythematosus (SLE) is a chronic, multifactorial autoimmune disorder in which the immune system mistakenly attacks the body’s own tissues. This leads to widespread
inflammation, tissue damage, and organ dysfunction. SLE can affect nearly every system in the body, but it most commonly involves the skin, joints, kidneys, blood, and nervous system. Classic symptoms include a distinctive
malar rash (often described as a “butterfly rash”),
joint pain,
fever,
fatigue,
hair loss, and mouth ulcers, among others. The disease is known for its clinical heterogeneity – both in the intensity of symptom manifestations and in the distribution of affected organ systems – making diagnosis and subsequent treatment challenging.
Current Treatment Approaches
Treatment for SLE traditionally involves using a combination of immunosuppressants, corticosteroids, and nonsteroidal anti-inflammatory drugs (NSAIDs) to manage disease activity and prevent organ damage. Over the years, novel therapeutic agents have emerged in response to the limitations of conventional treatments, particularly regarding their side effects and limited efficacy in many patients. A few significant biologic therapies, such as belimumab, anifrolumab, and telitacicept, have received regulatory approval, providing new hope to a historically underserved market. These innovative treatments target various immune system pathways and aim to reduce autoantibody production, dampen systemic inflammation, and ultimately improve long-term outcomes in patients with SLE.
