Overview
Sjögren's syndrome is a complex and multifaceted condition that affects millions of people worldwide. It is a chronic autoimmune disorder that occurs when the immune system mistakenly attacks the glands that produce tears and saliva, leading to inflammation and damage. This damage causes the glands to produce less tears and saliva, resulting in dryness and discomfort in the eyes and mouth. Sjögren's syndrome can also affect other parts of the body, including the skin, joints, and lungs. While the exact cause of Sjögren's syndrome is unknown, it is believed to be triggered by a combination of genetic and environmental factors.Symptoms of Sjögren's syndrome can vary widely from person to person, but common symptoms include dry eyes, dry mouth, fatigue, joint pain, and skin rashes. In some cases, Sjögren's syndrome can also cause more severe symptoms, such as difficulty swallowing, vision problems, and respiratory issues. If left untreated, Sjögren's syndrome can lead to serious complications, including scarring of the eyes and mouth, and an increased risk of infections.
History/Background
Sjögren's syndrome was first described by Swedish ophthalmologist Henrik Sjögren in 1933. Sjögren's initial observations were based on a series of patients who presented with dry eyes and dry mouth, and he proposed that these symptoms were related to an autoimmune disorder. Over the years, Sjögren's syndrome has been extensively studied, and it is now recognized as a distinct medical condition. In 2002, the American College of Rheumatology (ACR) established a set of criteria for diagnosing Sjögren's syndrome, which includes a combination of clinical and laboratory tests.Key Information
