Study Notes
- Autoimmune diseases are a diverse category of disorders characterized by the body's immune system attacking its own cells and tissues, leading to inflammation and damage.
- Common symptoms include fatigue, low-grade fever, malaise, muscle aches, joint pain, and skin rashes.
- Symptoms can vary greatly depending on the type of disease and the organs affected.
- Some common autoimmune diseases include celiac disease, type 1 diabetes, Graves' disease, inflammatory bowel diseases, multiple sclerosis, alopecia areata, Addison's disease, pernicious anemia, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus.
- Diagnosis and treatment of autoimmune diseases can be challenging due to their diverse presentations and the need for long-term management.
- Prevalence of autoimmune diseases is significant, with approximately 10% of the population affected, and women being more commonly affected than men.
- Commonly used treatments include nonsteroidal anti-inflammatory drugs, immunosuppressants, and intravenous immunoglobulin.
- Coeliac disease is an autoimmune reaction to gluten, leading to damage to the small intestine and increasing the risk of gastrointestinal cancers.
- Graves' disease is characterized by autoantibodies to thyroid-stimulating hormone receptors, resulting in unregulated production and release of thyroid hormones.
- Other common autoimmune diseases include celiac disease, type 1 diabetes, Graves' disease, inflammatory bowel diseases, multiple sclerosis, alopecia areata, Addison's disease, pernicious anemia, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus.
- Symptoms of autoimmune diseases can vary greatly, and an individual may have more than one autoimmune disease.
- Treatment approaches include managing symptoms, reducing immune system activity, and maintaining the body's ability to fight diseases.
- Advancements in understanding and management of autoimmune diseases have been substantial since their initial recognition in the early 1900s.
