Study Notes
Introduction to Connective Tissue Disorders
- Connective tissue diseases affect structures connecting various body parts, involving joints, muscles, skin, and potentially other organs such as eyes, heart, lungs, and kidneys.
- Comprised of two primary proteins: collagen (provides strength) and elastin (provides elasticity).
- Over 200 types of connective tissue diseases exist, categorized into heritable and non-heritable disorders.
Types of Connective Tissue Diseases
- Non-heritable Disorders: Acquired autoimmune and inflammatory diseases that typically develop later in life.
- Heritable Disorders: Genetic defects present at birth, leading to heritable disorders of connective tissue (HDCT).
- Examples of disorders:
- Churg-Strauss Syndrome: Blood vessel inflammation affecting organs like the digestive system and lungs.
- Dermatomyositis/Polymyositis: Inflammation impacting muscle tissues and skin.
- Granulomatosis with Polyangiitis: Affects blood vessels in the nose, kidneys, and lungs.
- Microscopic Polyangiitis: Rare condition affecting blood vessels in various organs.
- Rheumatoid Arthritis: Autoimmune disease causing joint inflammation, more common in women.
- Scleroderma: Causes skin and organ scarring, predominantly affecting women of childbearing age.
- Systemic Lupus Erythematosus: Connective tissue inflammation impacting multiple body systems.
- Examples of disorders:
Causes of Connective Tissue Diseases
- Can be inherited (genetic defects) or acquired through environmental factors.
- Environmental Triggers:
- Exposure to toxic chemicals (air pollution, cigarette smoke).
- Ultraviolet light exposure.
- Nutritional deficiencies (lack of vitamins D and C).
- Infections may also contribute.
- Environmental Triggers:
General Signs and Symptoms
- Symptoms can vary widely based on the affected areas.
- Common symptoms include:
- General malaise and increased fatigue.
- Raynaud's phenomenon: Cold/numb fingers or toes that change colors.
- Swollen fingers/hands and joint/muscle pain.
- Rashes, particularly over the knuckles.
- Respiratory Symptoms: Difficulty breathing, fatigue, cough with bloody phlegm, chest discomfort.
- Common symptoms include:
Diagnostic Procedures
- Comprehensive assessment includes:
- Detailed medical and family history, physical examination.
- Imaging tests (X-rays, MRI scans).
- Inflammatory marker tests (C-reactive protein, ESR).
- Complete blood count (CBC) may reveal anemia, thrombocytopenia, and leukopenia.
- Antibody tests for autoimmune conditions.
- Dry eye and mouth tests, blood and urine tests, and possible tissue biopsy.
Treatment Approaches
- Treatment plans are tailored based on specific diagnoses.
- Corticosteroids are often used for inflammation reduction.
- Physical and occupational therapy may support daily living adjustments.
- Use of physical aids (braces, canes) may be necessary.
- Pain management strategies may be required.
- Careful evaluation of treatment risks and benefits alongside a neurologist.
