Study Notes
Autoimmune Diseases
- Autoimmune diseases occur when the immune system mistakenly attacks the body's own tissues.
- Important examples include rheumatoid arthritis, multiple sclerosis, type 1 diabetes, Graves' disease, and myasthenia gravis.
- The exact cause of many autoimmune diseases is unknown.
- It is believed that pathogenic antibodies or immune cells (like T cells) cause or contribute to tissue damage.
- Autoimmune diseases are common, affecting an estimated 8 million people in the US alone.
- They often affect young adults.
- Most autoimmune diseases are chronic.
- There is currently no cure for most autoimmune diseases, but treatments exist that can manage symptoms.
Immune System Related Diseases
- Autoimmune diseases represent a category of immune system-related disorders, along with hypersensitivity disorders (allergies) and immunodeficiencies.
- Neoplasia (like leukemia, lymphoma) is also considered an immune system-related condition.
Classification of Autoimmune Diseases
- Organ-specific diseases affect specific organs or tissues.
- Antibody-mediated: Graves' disease, myasthenia gravis, Goodpasture's syndrome.
- Cell-mediated: multiple sclerosis, type 1 diabetes.
- Systemic diseases affect multiple organ systems.
- Systemic lupus erythematosus
- Rheumatoid arthritis
Graves' Disease (Basedow)
- Also known as diffuse toxic goiter.
- An autoimmune disorder causing overactive thyroid function.
- Characterized by autoimmune-induced thyroid gland overactivity.
Myasthenia Gravis (MG)
- An autoimmune disease that impacts neuromuscular junctions.
- Autoantibodies against acetylcholine receptors block muscle activation.
- This leads to progressive muscle weakness.
Goodpasture's Syndrome
- Autoimmune disease leading to lung and kidney damage.
- Destructive autoantibodies are a key feature.
- Often presents with symptoms like hemoptysis (coughing up blood) and kidney problems.
Type 1 Diabetes Mellitus (IDDM)
- Autoimmune attack on the insulin-producing cells in the pancreas (Islets of Langerhans).
- Insulin is critical for regulating blood glucose.
- Lack of insulin results in high blood sugar (hyperglycemia).
- Classic symptoms include excessive urination, thirst, and increased appetite.
- Diagnosis can involve blood tests to measure glucose and insulin levels.
- Treatment primarily involves insulin administration.
Hashimoto's Thyroiditis
- An autoimmune disease causing hypothyroidism (underactive thyroid).
- Characterized by inflammation and infiltration of the thyroid gland.
- Leads to reduced thyroid hormone production.
Multiple Sclerosis (MS)
- A chronic, autoimmune disease affecting the central nervous system (CNS).
- Characterized by demyelination (damage to nerve sheaths).
- Symptoms can vary significantly and include neurologic deficits.
- Forms of MS include relapsing-remitting and progressive.
Systemic Lupus Erythematosus (SLE)
- A chronic, multisystem autoimmune disorder.
- Characterized by widespread inflammation and immune complex formation.
- Symptoms can range from fatigue and joint pain to skin rashes, kidney problems, and neurological symptoms.
- Clinical picture often includes butterfly rash, photosensitivity, and joint pain.
Rheumatoid Arthritis (RA)
- A chronic inflammatory autoimmune disease primarily affecting the joints.
- Characterized by chronic inflammation in the synovial membrane.
- Often leads to joint pain, stiffness, and swelling.
- Potential for systemic involvement.
- Diagnosis often involves antibody testing and examination of joint inflammation.
