Overview of Arthritis and Gout

Arthritis Overview

• Arthritis encompasses various conditions, including osteoarthritis, rheumatoid arthritis, and gout.

Gout Arthritis

• Characterized by deposition of monosodium urate (MSU) crystals.
• Hyperuricemia is a key factor, with levels exceeding 7 mg/dL in men and 6 mg/dL in women.
• Pain, swelling, and inflammation are common symptoms, frequently affecting the big toe (podagra).
• Crystals are needle-shaped.
• Distinguished from pseudogout by crystal morphology (needle-shaped vs. rhomboid/rod-shaped).
• Early diagnosis and management are crucial for preventing long-term joint damage.

Gout Arthritis vs Pseudogout

• Gout involves monosodium urate (MSU) crystals.
• Pseudogout involves calcium pyrophosphate dihydrate (CPPD) crystals.

Osteoarthritis

• Characterized by cartilage breakdown and bone spurs (osteophytes).
• Common symptoms include joint pain, stiffness, especially in the morning, and reduced range of motion (ROM).
• Affected areas often include hips, knees, hands (especially distal interphalangeal joints).
• Cartilage thinning and bone rubbing contribute to symptoms.
• Osteophytes develop as the cartilage wears away.
• Inflammation is not typically as severe compared to rheumatoid arthritis.
• May be associated with joint stiffness, pain, and limited motion; usually worse after activity.
• The progression of osteoarthritis is often determined by the presence of osteophytes, joint space narrowing and sclerosis of bones.
• Different grading systems categorize the severity of cartilage damage and bone changes.

Rheumatoid Arthritis (RA)

• A chronic autoimmune inflammatory disease affecting joints.
• Inflammation leads to joint damage, often symmetrically.
• Symptoms often include morning stiffness lasting over 30 minutes, affecting multiple joints.
• RA can affect various tissues beyond joints.
• Characterized by inflammation of the synovial membrane that lines the joint. This process can damage the cartilage and bone, leading to joint deformities.
• RA is often linked to genetic and hormonal factors.
• The inflammatory process of RA can impact various organs within the body.
• Symptoms frequently include symmetrical swelling and tenderness in multiple joints, accompanied by systemic symptoms such as fever, fatigue, and weight loss.
• Possible deformities include boutonniere deformity and swan-neck deformity.

RA vs OA

• RA often features symmetrical joint involvement, while OA is typically asymmetrical.
• In RA, morning stiffness usually lasts longer than in OA.
• RA commonly involves systemic manifestations beyond joints.

Treatment

• Dietary modifications are important for gout to manage uric acid levels.
• Non-pharmacological therapies include patient education, lifestyle modifications, and exercise programs.
• Medications and biological agents (e.g., TNF inhibitors, B-cell blockers, and anti-IL-1 and IL-6 agents) may be prescribed for some types of arthritis.
