Arthritis Comprehensive Checkup

Arthritis is a general term that refers to a group of more than 100 conditions all of which primarily involve inflammation of the joints leading to joint pain, stiffness, swelling and reduced mobility. Arthritis is one of the most common causes of chronic pain and disability, and though it is more prevalent in older adults it can affect all age groups.

Arthritis can affect any joint, but is most common in:

• Hands and wrists.
• Knees
• Hips
• Feet and ankles.
• Shoulders
• Lower back (lumbar spine).
• Neck

While arthritis is primarily known for its impact on the joints, it can also have systemic effects depending on the type. For example, rheumatoid arthritis, an autoimmune form of the disease, can affect other organs such as the heart, lungs, and eyes. Similarly, conditions like lupus and ankylosing spondylitis can involve inflammation beyond the joints, affecting the skin, spine, and the cardiovascular system. The diversity in its causes and manifestations makes arthritis a complex condition, requiring a comprehensive understanding and approach for effective management.

Types of Arthritis

There are over 100 different types of arthritis, each with unique variations in its development, causes, affected joints, symptoms, distinguishing characteristics, and overall impact on a person’s health. The most common types include:

Osteoarthritis (OA):

Osteoarthritis, degenerative joint disease, is the most common form of arthritis that occurs when the cartilage that cushions the ends of bones in the joints gradually deteriorates. As cartilage wears away, bones may rub against each other, leading to pain, swelling, and reduced joint movement.

Rheumatoid Arthritis (RA):

RA is the most common form of autoimmune arthritis where the body’s immune system mistakenly attacks the lining of the membranes surrounding the joints causing inflammation, joint damage, pain, and swelling.

Gout:

Gout is the most common form of inflammatory arthritis which occurs when urate crystals accumulate in the joint, causing inflammation and intense pain. Urate crystals are very small deposits that form in the joints and tissues when there is an excess of uric acid in the blood. Symptoms of gout include sudden and severe pain in a joint, often the big toe; redness, warmth, and swelling in the affected joint.

Psoriatic Arthritis

Psoriatic arthritis occurs in some people who have psoriasis, a skin disorder characterized by red, scaly patches. This type of arthritis causes joint pain, swelling, and stiffness, often affecting the fingers, toes, and lower back, and can also lead to changes in the nails, such as pitting or separation from the nail bed.

Certain arthritis types are less common than others. These include:

Ankylosing spondylitis (AS)

Ankylosing spondylitis is a kind of chronic inflammatory arthritis primarily affecting the spine and the sacroiliac joints, leading to pain and stiffness. Over time, inflammation can cause some of the vertebrae to fuse, resulting in a loss of flexibility and potentially leading to a hunched posture. AS can also affect other joints and organs, including the eyes, heart, and lungs.

Palindromic rheumatism (PR):

Palindromic rheumatism is a rare, episodic form of inflammatory arthritis characterized by sudden and recurrent attacks of joint pain and swelling, typically affecting one or several joints at a time in the hands, wrists, knees, and ankles. These episodes can last from hours to days and then completely resolve, leaving no permanent damage or lasting symptoms between attacks.

Reactive arthritis

Reactive arthritis is a type of inflammatory arthritis that develops in response to a bacterial infection in another part of the body, most commonly in the gastrointestinal or genitourinary tract or from a sexually transmitted infection. It typically causes pain, swelling, and stiffness in the joints, particularly in the knees, ankles, and feet, and may also involve the eyes, skin, and urinary system. While the symptoms of reactive arthritis can be severe, they often resolve within a few months, though some individuals may experience recurrent or chronic symptoms.

Key Components of Arthritis Checkup

Diagnosing arthritis involves a combination of clinical evaluation, laboratory tests, and imaging studies to accurately determine the type of arthritis and its severity. In Cuba, this process typically begins with a detailed medical history, where information on symptoms such as joint pain, stiffness, swelling, and the duration and pattern of these symptoms are gathered.

Medical History

A medical history review typically includes:

• Symptom Inquiry:
  • Assess joint pain, stiffness, swelling.
  • Determine the duration and pattern of symptoms (e.g., morning stiffness, pain that improves with activity).
  • Inquire about the presence of systemic symptoms like fatigue, fever, or weight loss.
• Family History:
  • Evaluate any family history of arthritis or autoimmune diseases.
• Risk Factors:
  • Consider risk factors such as age, gender, previous joint injuries, infections, and lifestyle factors (e.g., smoking, obesity, sedentary lifestyle).

Physical Examination

Physical examination provides direct assessment for joint tenderness, swelling, range of motion, and signs of inflammation, helping to identify the type and severity of the condition.

• Joint Examination:
  • Inspect for visible swelling, redness, or deformity.
  • Palpate joints to assess tenderness and warmth.
  • Evaluate range of motion and joint function.
• Systemic Examination:
  • Check for signs of systemic involvement, such as skin rashes (psoriasis), eye redness or pain (uveitis), or nodules under the skin.

Laboratory Tests

Laboratory tests provide information that cannot be obtained through physical examination alone. These tests help detect markers of inflammation and autoimmune markers. Laboratory tests also aid in ruling out other conditions that mimic arthritis symptoms, ensuring an accurate diagnosis.

• Blood Tests:
  • Inflammatory Markers:
    • C-reactive protein (CRP).
    • Erythrocyte sedimentation rate (ESR).
  • Autoimmune Markers:
    • Rheumatoid factor (RF).
    • Anti-cyclic citrullinated peptide (anti-CCP) antibodies.
    • Antinuclear antibodies (ANA) for lupus.
  • Other Specific Tests:
    • Uric acid levels for gout.
    • HLA-B27 genetic marker for ankylosing spondylitis.
  • Joint Fluid Analysis (Arthrocentesis):
    • Extract synovial fluid from the affected joint to look for:
      • Crystal presence (uric acid crystals in gout).
      • Infection (presence of bacteria or white blood cells).
      • Inflammatory cells or other abnormalities.

Imaging Studies

Imaging studies provide detailed visual insights into the structure and condition of joints, bones, and surrounding tissues that cannot be fully assessed through physical examination or laboratory tests alone to identify the specific type of arthritis, assessing the extent of joint damage, and guiding treatment decisions.

• X-rays:
  • Assess joint space narrowing, bone erosion, osteophytes (bone spurs), and calcifications.
• Magnetic Resonance Imaging (MRI):
  • Provide detailed images of soft tissues, including cartilage, tendons, and ligaments.
  • Detect early signs of joint damage not visible on X-rays.
• Ultrasound:
  • Evaluate soft tissue structures around joints (e.g., synovium, tendons).
  • Identify joint effusion (fluid accumulation) and inflammation.

Diagnosis and Classification

Diagnosis and classification involve the identification of the specific type of arthritis and categorizing it based on established criteria.

• Differential Diagnosis:
  • Rule out other conditions that may mimic arthritis symptoms, such as fibromyalgia or Lyme disease.
• Specific Arthritis Diagnosis:
  • Classify the type of arthritis based on all collected data (e.g., osteoarthritis, rheumatoid arthritis, psoriatic arthritis, gout, ankylosing spondylitis).
• Severity Assessment:
  • Assess the extent of joint damage and overall disease activity.
  • Use tools like the Disease Activity Score (DAS) for rheumatoid arthritis.

Treatment Planning

Based on the specific type and severity of arthritis, as well as the individual patient’s overall health, lifestyle, and any coexisting medical conditions, an individualized management plan is carefully developed to address the unique needs and challenges associated with their condition. This plan typically includes a combination of medications, physical therapy, lifestyle modifications, and possibly surgical interventions, all tailored to optimize symptom control, improve joint function, and enhance the patient’s overall quality of life.
