Idiopathic arthritis refers to a group of chronic inflammatory joint diseases with no identifiable cause.
The term βidiopathicβ means that the specific cause of the arthritis is unknown.
π Types
- π€² Rheumatoid Arthritis (RA): A systemic autoimmune disease causing chronic joint inflammation, leading to damage and deformities.
- 𦴠Osteoarthritis (OA): A degenerative joint disease marked by breakdown of cartilage and underlying bone, causing pain and stiffness.
- πΆ Juvenile Idiopathic Arthritis (JIA): Usually diagnosed in children but may persist into adulthood, resembling RA.
- π¨ Psoriatic Arthritis (PsA): Associated with psoriasis; causes joint inflammation with swelling, pain, and stiffness.
- π¦ Reactive Arthritis: Triggered after an infection (e.g., gastrointestinal or urinary tract), leading to joint inflammation.
β οΈ Symptoms
- Joint pain and tenderness π€
- Swelling and warmth π‘οΈ
- Morning stiffness or stiffness after inactivity β³
- Reduced range of motion π
- Fatigue and malaise π΄
- Systemic signs (fever, weight loss) in some cases π
π§ͺ Diagnosis
- π Medical History: Symptoms, family history, and medical background.
- π©Ί Physical Exam: Assess tenderness, swelling, range of motion.
- 𧬠Laboratory Tests: Rheumatoid factor (RF), anti-CCP antibodies, ESR, CRP.
- π©» Imaging: X-rays, MRI, or ultrasound for joint changes.
- π Arthrocentesis: Joint fluid analysis to exclude infection or gout.
π Management
- Medications:
- NSAIDs for pain & inflammation π₯
- DMARDs (e.g., methotrexate) to slow disease progression β³
- Biologic agents (e.g., TNF inhibitors) π―
- Corticosteroids for flares π
- ποΈ Physical Therapy: To maintain joint function and muscle strength.
- π¦Ύ Joint Protection: Use of orthotics and supportive devices.
- π§ Surgery: Joint replacement or repair in severe cases.
π Prognosis
- Course varies between individuals. β±οΈ Early diagnosis and treatment improve long-term joint preservation and quality of life.
