Study Notes
Autoimmune Disease
- Also known as inflammatory disease, characterized by self-cells being attacked and damaged, leading to constant/chronic inflammation
- Attacking specific cells, organs, or areas
- Inflammation is the body's reaction to infection, irritation, or other injuries, and is part of the immune response
Classification of Autoimmune Disease
- Systemic Autoimmune Diseases: damage many organs, e.g. Rheumatoid arthritis, Sjogren's syndrome, Lupus Erythematosus, Scleroderma
- Localized Autoimmune Diseases: damage a single organ or tissue, e.g. Type 1 Diabetes Mellitus, Hashimoto's thyroiditis, Celiac disease, Crohn's disease
Cause of Autoimmune Disease
- Unknown, but appears to be an inherited predisposition to develop autoimmune disease in many cases
- In some cases, a bacteria or virus triggers an immune response, and the antibodies or T-cells attack normal cells because they have similar structures to the infecting microorganism
Risk Factors
- Genetic factor
- Environmental toxins
- Gender: most autoimmune diseases tend to show a female preponderance
- Heredity
- Viruses
- Drugs
- Stress
- Poor diet
- Lack of exercise
- Lack of sleep
- Abuse of alcohol and tobacco
Symptoms of Autoimmune Diseases
- Fatigue
- Affect on weight
- Muscle pain
- Insomnia
- Inflammation
Specific Autoimmune Diseases
- Crohn's disease: inflammation of the gastro-intestinal tract, affects 400,000 to 600,000 people in North America
- Rheumatoid arthritis: inflammation of synovial joints, often leads to destruction of articular cartilage, affects 1% of the world's population
- Multiple Sclerosis: inflammation leading to demyelination of axons in the brain and spinal cord, affects 2 to 150 per 100,000 in the world
- Systemic Lupus Erythematosus: inflammation occurs almost anywhere in the body, including heart, lungs, and nervous system, affects 3-8% of the population in the United States, tends to be chronic, and 80% of those affected are women
How Stress Predisposes to the Development of Autoimmune Disease
- Alteration of one or many components of the immune system
- Increased susceptibility to infectious diseases
- Stress leads to higher likelihood of catching cold and infections
- Inability to fight off infections, leading to a less efficient immune system
Studies on Autoimmune Disease
- Study on Multiple Sclerosis: respiratory viral infection frequently precedes exacerbation of MS, stress as a common denominator
- Study on Childhood Stress and Later AD: early life experiences (adverse) can affect the immune system later on, 2+ adverse childhood events increase the risk of developing AD
- Study on Lupus Erythematosus: daily stress increases perceived symptomatology of lupus patients, prolactin increase
- Study on Stress-vulnerability Rheumatoid Arthritis: stress affects the course of disease activity, 'coping with stress' and 'social support' are two factors strongly related to disease activity### Stress and Autoimmune Diseases
- Stress and coping mechanisms are strongly related to autoimmune disease activity
- Low social support is linked to increased disease activity, while high social support is linked to reduced disease activity
- Avoidance coping mechanisms are associated with increased disease activity, while low avoidance coping is linked to reduced disease activity
Autoimmune Diseases
- Defined as a heterogeneous group of 70-80 inflammatory disorders
- Occurs when the immune response damages tissues in the body
- Affects 3-8% of the population in the United States
- 80% of autoimmune disease patients are women
- Can be classified into two categories: systemic autoimmune diseases and localized autoimmune diseases
Systemic Autoimmune Diseases
- Damage multiple organs in the body
- Examples include:
- Rheumatoid arthritis (RA)
- Sjogren's syndrome
- Lupus Erythematosus
- Scleroderma
Localized Autoimmune Diseases
- Damage a single organ or tissue in the body
- Examples include:
- Type 1 Diabetes Mellitus (pancreas)
- Hashimoto's thyroiditis (thyroid)
- Celiac disease (intestinal)
- Crohn's disease (small intestine)
Causes and Risk Factors
- Unknown, but inherited predisposition is suspected
- Triggered by bacteria or viruses in some cases
- Risk factors include:
- Genetic factor
- Environmental toxins
- Gender
- Heredity
- Viruses
- Drugs
- Stress
- Poor diet
- Lack of exercise
- Lack of sleep
- Abuse of alcohol and tobacco
Symptoms
- Fatigue
- Weight changes
- Muscle pain
- Insomnia
- Inflammation
Stress and Immune System
- Stress can alter the immune system, making it more susceptible to infections
- Stress can suppress the immune system, making it less efficient to fight off infections
- Stress can trigger immune system malfunction, attacking self-cells
Studies
- Study on Multiple Sclerosis: stress is a common denominator in the development of MS
- Study on Childhood Stress and Later AD: early life experiences can affect the immune system later in life
- Study on Lupus Erythematosus: daily stress increases perceived symptomatology of lupus patients
