Types of Arthritis : its Causes, and Symptoms Class 12 (common diseases)

What is Arthritis?

Definition and Types

Arthritis refers to the inflammation of one or more joints in the body, resulting in pain, stiffness, and decreased range of motion. Arthritis can be classified into numerous categories, including:

1. Osteoarthritis (OA)

 ◾  The most common type of arthritis, typically affecting older individuals. The slow breakdown of cartilage in joints causes this condition. Commonly affects weight-bearing joints like knees, hips, and spine.

2. Rheumatoid Arthritis (RA)

 ◾  A condition in which the immune system hurts the joints. Results in chronic inflammation, joint damage, and systemic effects. Affects multiple joints symmetrically, often including hands and feet.

3. Psoriatic Arthritis (PsA)

 ◾  Psoriatic arthritis is a kind of arthritis that arises in people who have psoriasis. This condition causes joint pain, stiffness, and edema, as well as skin problems. Can affect any joint, including fingers, toes, and the spine.

4. Gout

 ◾  The deposition of uric acid crystals in joints defines this condition. Typically affects the big toe, causing sudden and severe pain. Dietary factors, alcohol consumption, and genetics contribute to its development.

5. Ankylosing Spondylitis (AS)  

 ◾  A chronic inflammatory arthritis affecting the spine and sacroiliac joints. Results in stiffness, pain, and limited mobility in the spine and pelvis. Often manifests in young adults and has a genetic predisposition.

Prevalence and Impact

1. Global Statistics

 ◾  An estimated 350 million individuals worldwide suffer from arthritis. Osteoarthritis is the most prevalent type, followed by rheumatoid arthritis. The prevalence of arthritis is expected to rise due to aging populations and lifestyle factors.

2. Age and Gender Patterns

 ◾  Arthritis can affect people of all ages, including children and young people. Osteoarthritis is more common in older adults, while rheumatoid arthritis has a higher prevalence in women.

3. Economic and Social Burden

 ◾  Arthritis leads to significant healthcare costs, lost productivity, and disability. It can impact an individual's ability to work, perform daily activities, and maintain social connections.

Causes and Risk Factors

A. Genetic Factors

1. Family History

• A family history of arthritis increases the risk of developing the condition. Certain genes and genetic variations play a role in predisposition to arthritis.

2. Genetic Markers

• Researchers have identified specific genetic markers associated with different types of arthritis. These markers can help in early diagnosis and personalized treatment approaches.

•  Chronic Kidney Disease Stage 3

B. Environmental Factors

1. Infections

 ◾  Certain infections, such as bacterial or viral infections, can trigger arthritis in susceptible individuals. Reactive arthritis is an example of arthritis associated with bacterial infections.

2. Smoking and Alcohol

 ◾  Smoking and excessive alcohol consumption have been linked to an increased risk of developing arthritis, particularly rheumatoid arthritis.

3. Obesity and Poor Diet

 ◾  Excess body weight puts stress on joints, increasing the risk of osteoarthritis. A diet high in processed foods, sugar, and saturated fats can contribute to inflammation and joint damage.

C. Lifestyle Factors

1. Repetitive Movements

 ◾  Occupations or activities that involve repetitive joint movements can lead to arthritis over time. Examples include jobs that require frequent kneeling, squatting, or heavy lifting.

2. Occupational Hazards

 ◾  Exposure to certain chemicals or toxins in the workplace may increase the risk of developing arthritis. Individuals in occupations like construction, agriculture, and manufacturing may be at higher risk.

3. Sports Injuries

 ◾  Traumatic joint injuries, such as those experienced in sports or accidents, can lead to arthritis later in life. Inadequate treatment or rehabilitation after an injury can contribute to joint damage.

Symptoms and Diagnosis

A. Common Symptoms

1. Joint Pain and Stiffness

 ◾  Persistent pain, tenderness, or aching in one or more joints. Stiffness and difficulty moving joints, especially after periods of inactivity.

2. Swelling and Redness

 ◾  Inflammation in the joints, leading to swelling, warmth, and redness. Visible joint swelling may be more prominent in certain types of arthritis.

3. Reduced Range of Motion

 ◾  Difficulty or limited ability to fully move or bend affected joints. Joint stiffness can result in decreased flexibility and impaired daily activities.

•  TB (Tuberculosis)

B. Diagnosis and Medical Evaluation

1. Physical Examination

 ◾  A healthcare professional assesses joint tenderness, swelling, warmth, and range of motion. They may also inquire about symptoms, medical history, and perform specific maneuvers to evaluate joint function.

2. Imaging Tests

 ◾  X-rays, MRIs, and ultrasound scans can help visualize joint damage, inflammation, or structural abnormalities. These tests aid in diagnosing and monitoring the progression of arthritis.

3. Blood Tests

 ◾  Blood tests can detect certain markers, such as rheumatoid factor and anti-cyclic citrullinated peptide (anti-CCP) antibodies, indicative of rheumatoid arthritis. Elevated levels of uric acid in the blood can suggest gout.

Effective Management Strategies

A. Medications and Pain Relief

1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

 ◾  Commonly used to reduce pain, inflammation, and stiffness in arthritis. Examples include ibuprofen, naproxen, and aspirin (in low doses).

2. Disease-Modifying Antirheumatic Drugs (DMARDs)

 ◾  Medications that slow down the progression of certain types of arthritis, such as rheumatoid arthritis. Methotrexate, sulfasalazine, and hydroxychloroquine are commonly prescribed DMARDs.

3. Biologic Response Modifiers (BRMs)

 ◾  Biologic medications that target specific molecules involved in the immune system's inflammatory response. Used for moderate to severe rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis.

B. Lifestyle Modifications

1. Exercise and Physical Therapy

 ◾  Regular low-impact exercises improve joint flexibility, strength, and overall function. Physical therapy can help manage pain, enhance mobility, and provide guidance on exercises tailored to individual needs.

2. Weight Management

 ◾  Maintaining a healthy weight reduces stress on joints, particularly in weight-bearing areas. Weight loss can alleviate symptoms and slow down the progression of arthritis.

3. Assistive Devices and Adaptive Equipment

 ◾  The use of assistive devices such as braces, canes, or splints can provide support and relieve joint stress. Adaptive equipment modifications in the home or workplace can facilitate daily activities.
