Systemic lupus erythematosus (SLE)

Overview

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease in which the immune system mistakenly attacks the body’s own healthy tissues, leading to widespread inflammation and damage throughout the body. SLE can affect many organs and systems, including the skin, joints, kidneys, lungs, heart, brain, blood cells, and blood vessels. Symptoms and severity vary widely between individuals, ranging from mild flare-ups to serious complications such as lupus nephritis, cardiovascular disease, neurological involvement, and blood-clotting disorders.

Common Symptoms

Skin rashes, fatigue, low fevers, pain or swelling of the joints, lung problems, kidney problems, and heart problems.

Coexisting Diseases and Conditions

Lupus nephritis, rheumatoid arthritis, cardiovascular disease, osteoporosis, Sjögren’s syndrome, vascular disease, Graves’ disease, and Hashimoto’s thyroiditis.

Risk Factors and Prevalence

SLE has a greater risk of occurring in females, with a 9:1 female to male ratio of disease incidence. Age is another risk factor, with diagnosis most commonly occurring between the ages of 15 and 44. Studies have also shown a greater prevalence of SLE among Blacks, Hispanic/Latino, and Asian populations.
