Rheumatological Assessment Study Guide

Introduction to the Rheumatological Assessment

  • Presented by the University Hospital of the West Indies.

Objectives

  • Importance of Patient History

    • Emphasizes the role of comprehensive history in evaluating rheumatic diseases.

  • Differentiation of Joint Diseases

    • Ability to distinguish between inflammatory and structural joint diseases.

  • Patterns of Joint Involvement

    • Use of joint involvement patterns to assist in diagnosing rheumatic diseases.

  • Extra-Articular Manifestations

    • Recognition of extra-articular manifestations as critical diagnostic clues for rheumatic diseases.

Rheumatic Disease History

  • Chief Complaint: Listening to the patient's primary concern.

  • Chronology of Illness: Understanding timeline and progression of the condition.

  • Acute vs. Chronic: Differentiating between short-term (acute) and long-term (chronic) conditions.

  • Demographics of Patient: Obtaining relevant demographic information.

  • Family History: Inquiring about familial patterns of diseases.

  • Prior Evaluations and Treatments: Summary of past interventions and their effectiveness.

  • Functional Impact: Assessment of how the disease impacts daily activities, including the use of assistive devices.

  • Review of Systems: Comprehensive review of related symptoms across systems.

Functional Classification

  • Total Ability: Completely able to carry out all daily living duties.

  • Limited Capacity: Able to perform usual self-care and vocational activities but limited in leisure activities.

  • Moderate Limitations: Can perform usual self-care activities but is limited in both vocational and leisure activities.

  • Severe Limitations: Significant limitations in self-care, vocational, and leisure activities.

  • Assistive Devices: Evaluation of patient's use of assistive aids.

Evaluation of the Patient with Arthritis

  • Length of Symptoms:

    • Acute: Symptoms present for less than 2 weeks.

    • Subacute: Symptoms lasting between 2 and 6 weeks.

    • Chronic: Symptoms persisting for more than 6 weeks.

  • Pain Assessment:

    • Location: Specific areas of pain (articular, periarticular, non-articular).

    • Timing: Patterns of pain related to activity versus rest; nocturnal pain.

    • Character: Quality of pain (sharp, dull, constant, or intermittent).

    • Morning Stiffness: Duration of stiffness, particularly if it lasts more than 30 minutes, suggestive of inflammatory arthritis.

    • Demographics: Gathering demographic information of the patient for contextual evaluation.

    • Extra-Articular Symptoms: Identifying symptoms outside of joint involvement to assist in diagnosis.

Length of Symptoms and Associated Conditions

  • Acute (less than 2 weeks): Possible conditions include:

    • Infectious arthritis

    • Crystal arthritis

    • Reactive arthritis

    • Traumatic arthritis

  • Subacute (2-6 weeks): Overlap of acute and chronic rheumatic diseases.

  • Chronic (greater than 6 weeks):

    • Rheumatoid arthritis (RA)

    • Systemic connective tissue diseases (CTDs)

    • Spondyloarthritis (SpA)

    • Osteoarthritis (OA)

    • Chronic crystal arthropathy

    • Fibromyalgia syndrome (FMS)

Pain: Location, Character, and Timing

  • Prolonged Morning Stiffness (>30 minutes): Indicative of inflammatory arthritis like RA, CTDs, and SpA.

  • Symptoms with Activity: Suggestive of structural diseases such as osteoarthritis or avascular necrosis (AVN).

  • Severe Constant Pain: Associated with conditions like crystal arthritis or septic arthritis.

  • Prominent Nocturnal Pain: Possible indicator of bone or bone marrow tumors.

  • Burning Pain/Paresthesias: Often related to neuropathic disorders.

  • “Pain All Over”: Suggestive of fibromyalgia.

Location of Pain: Differential Diagnosis

  • Articular Pain: Pain associated with joint structures.

    • True hip pain: localized in the groin; often misdiagnosed.

    • True shoulder pain: localized in the glenohumeral region; can be mistaken for rotator cuff disease.

  • Non-Articular Pain: May have neurological or vascular causes; includes neuropathic pain.

Timing of Pain

  • Symptoms with activity indicate structural arthritis (OA, AVN).

  • Prolonged morning stiffness (>30 minutes) suggests inflammatory arthritis.

  • Severe and constant joint pain often indicates septic or crystal arthritis.

  • Prominent nocturnal joint pain may suggest bone tumors.

  • Burning pain or paresthesias prominent during nighttime: common in neuropathic disorders.

Demographics, Family and Social History

  • Factors to Consider:

    • Age: Specific diseases like Polymyalgia Rheumatica (PMR) and Giant Cell Arteritis.

    • Gender: For example, systemic lupus erythematosus (SLE) predominates in females; gout in males.

    • Ethnicity: Certain conditions more prevalent in specific ethnic groups (e.g., Behçet’s disease).

    • Geography/Travel: Consider Lyme disease as related to travel history.

    • Family History: Assess for inherited patterns like gout or psoriatic arthritis (PsA).

    • Social History: Evaluate functional status and use of functional aids.

Specific Age and Sex Distribution of Conditions

  • Rheumatoid Arthritis (RA): Common in ages 30-50 years (F:M ratio = 1:2.5).

  • Osteoarthritis (OA): Commonly seen in individuals over 50 years, slightly more in females.

  • Ankylosing Spondylitis (AS): Typically presents in ages 15-40 years (M:F ratio = 3:1).

  • Systemic Lupus Erythematosus (SLE): Affects primarily those aged 20-40 years (F:M ratio = 1:9).

  • Gout: Usually presents in individuals over 30 years (M:F ratio = 10:1).

  • Polymyalgia Rheumatica (PMR): Most common in those over 50 years (M:F ratio = 1:2).

  • Oligoarticular Juvenile Idiopathic Arthritis (JIA): Typically affects children aged 2 years (M:F ratio = 1:3).

  • Fibromyalgia Syndrome (FMS): Affects those aged 15-50 years (M:F ratio = 1:10).

Pattern of Joint Involvement in Arthritis

  • Monoarticular Involvement:

    • Acute causes: septic arthritis, crystal arthropathy, trauma.

    • Chronic causes: oligoarticular JIA, Lyme disease, AVN.

  • Oligoarticular Involvement (<4 joints):

    • Acute causes: septic arthritis, crystal arthropathy.

    • Chronic conditions: spondyloarthritis (SpA), oligoarticular JIA.

  • Polyarticular Involvement:

    • Acute causes: polyarticular JIA, acute rheumatic fever, crystal arthropathy.

    • Chronic conditions: rheumatoid arthritis (RA), osteoarthritis (OA), systemic CTDs.

Joint Patterns: Symmetry and Asymmetry

  • Symmetric Joint Involvement:

    • Common in RA, polyarticular JIA, OA, chronic crystal arthropathy, CTDs.

  • Asymmetric Joint Involvement:

    • Seen in SpA, oligoarticular JIA, and acute rheumatic fever.

Specificity in Joint Locations

  • Proximal & Distal Joints:

    • Proximal: common in RA, polyarticular JIA; Inflammatory like AS.

    • Distal: involved in OA, PsA, CTDs, and crystal arthropathy.

  • Lower Extremities: More often involved in SpA and crystal arthropathy.

  • Large Joints: Sepsis indication in large joint involvement.

Extra-Articular Symptoms and Signs

  • Constitutional Symptoms: Include fatigue, fever, chills, and weight changes.

  • Mucocutaneous Manifestations: Rashes, photosensitivity, and lymphadenopathy.

  • Pulmonary and Cardiovascular Involvement: Signs of systemic impact.

  • Gastrointestinal, Renal, and Genitourinary Symptoms: Need to assess related organ systems.

  • Hematologic and Neurologic Manifestations: Assess for broader impacts.

Constitutional Manifestations

  • Fatigue/Malaise: Associated with several rheumatic diseases such as RA, JIA, and CTDs.

  • Fever Patterns: Acute rheumatic fever characterized by intermittent daily fever.

  • Weight Fluctuations: Weight loss seen in connective tissue diseases, vasculitis.

  • Sleep Disturbances: Commonly reported in fibromyalgia and inflammatory arthritis.

Dermatologic Symptoms

  • Ask about rashes, lesions, and photosensitivity to assist with diagnosis.

  • Inspect skin areas like periungual, perirectal, umbilicus, nails, and hair for lesions.

  • Skin lesions can provide critical diagnostic insight.

Dermatologic Manifestations Overview

  • Suggestive Skin Rashes: Conditions like SLE, PsA, vasculitis show rashes.

  • Diagnostic Lesions: Lyme disease (Erythema migrans), dermatomyositis (Gottron’s papules).

  • Nail Changes: Observed in PsA and reactive arthritis; nodules in RA and gout (tophi).

  • Alopecia: Associated with SLE and connective tissue disorders.

Summary of Typical Patterns in Arthritis Evaluation

  • Distinction between Structural (e.g., OA) and Inflammatory (e.g., RA) patterns will guide diagnosis and treatment strategies.

  • Recognizing differences in symptoms, response to therapy, joint fluid characteristics, and imaging features is essential in the evaluation process.
