    Study Notes

    Classic Manifestations of Inflammation

    • Erythema: Redness of the skin, more pronounced on dark-colored skin.
    • Heat: Increased temperature, both local and systemic. Can be measured by touch or thermometer.
    • Swelling (Edema): Accumulation of fluid in tissues. Can be localized or generalized, affecting limbs, abdomen, lungs, or space around the lungs.
    • Pain: Unpleasant sensation, subjective experience described by the patient, can be acute or chronic.
    • Impaired function: Difficulty using the affected tissue or organ effectively.

    Localized vs. Generalized Inflammatory Response

    • Localized response: Limited to a specific area.
    • Generalized response: Affects the entire body.

    Chronic Inflammatory Conditions and Examples

    • Chronic inflammation can lead to structural changes.
    • Crohn disease: Fibrotic changes to the bowel wall, local obstruction, abscesses, fistulas, malabsorption, or malnutrition
    • Rheumatoid Arthritis (RA): Affects the lining of joints, causing joint deformity, pain, swelling, and erythema.

    Interventions/Treatments for Inflammation

    • Erythema: No intervention necessary if not bothersome, use good lighting for examination on darker-colored skin.
    • Heat: Antipyretics (acetaminophen, NSAIDs, aspirin), ice or cool packs.
    • Swelling: Diuretics, reduced sodium intake, treatment of underlying cause, medication assessment.
    • Pain: Analgesics (acetaminophen, NSAIDs, opioids), treatment of underlying cause, heat/ice, distraction, massage, relaxation techniques.
    • Impaired function: Treatment of underlying condition, physical therapy, analgesics, adequate sleep/rest.

    Altered Oxygenation

    • Inadequate oxygen intake, decreased ability to expel CO2, inadequate delivery of oxygen to tissues.
    • Manifestations: Cyanosis, labored breathing, dyspnea, ABG changes, abnormal lung sounds, chest tightness, difficulty clearing sputum, hypotension, heart dysrhythmia, fatigue, changes in skin color.
    • Intervention: Treatment of underlying condition, oxygen administration, bronchodilators, medication as prescribed, expectoration, adequate rest.

    Infection

    • Invasion of the body by microorganisms (bacteria, viruses).
    • Manifestations: Inflammation, pain, mucus production, purulent drainage, hyperthermia, malaise, nausea, vomiting, diarrhea, headache.
    • Intervention: Antibiotics or antivirals, antipyretics, analgesics, adequate rest, fluids/nutrition, wound care, surgical removal of infected part.

    Ankylosing Spondylitis

    • Form of arthritis primarily affecting the spine.
    • Manifestations: Vertebral inflammation leads to severe, chronic pain and discomfort.
    • Progression: Sacroiliac joints affected, new bone formation, fusion of spinal processes, fixed immobile posture (forward-stooped).

    Chronic Inflammatory Diseases

    • Chronic inflammatory diseases are a significant cause of death globally.
    • The World Health Organization considers chronic diseases the greatest threat to human health.
    • Over 100 chronic diseases have been identified.
    • It is estimated that 5-7% of the Western population is affected by at least one chronic disease.
    • It is impossible to determine the number of individuals experiencing acute inflammation at any given time.

    Genetic Considerations

    • Genome-wide association studies identified almost 450 genetic risk loci associated with pathological inflammation.
    • Each inflammatory disease has unique loci.
    • The IL-23/IL-17 pathway genes are a common pathway affected in many inflammatory diseases.

    Inflammation Response

    • The body's inflammatory response is a natural reaction to infection or injury.
    • It involves the activation of immune cells and the release of inflammatory mediators.
    • Inflammation aims to neutralize pathogens, remove damaged tissue, and initiate healing.
    • A localized infection causes localized inflammation with erythema and tenderness.
    • Widespread infection results in generalized inflammation, characterized by fever and generalized pain.

    Acute and Chronic Inflammation

    • Acute inflammation is a short-term response that resolves when the invading pathogen is eliminated.
    • Chronic inflammation can develop from persistent acute inflammation or arise independently.
    • Chronic inflammation can be disproportionate to the initial insult, leading to excessive tissue damage.
    • The body may incorrectly target its own healthy tissue in chronic inflammation, as seen in autoimmune disorders.

    Examples of Chronic Inflammatory Disorders

    • Crohn's disease and ulcerative colitis are examples of inflammatory bowel diseases where the body's immune system mistakenly attacks the gastrointestinal tract.

    Immune System and Autoimmune Diseases

    • The immune system plays a crucial role in inflammation by producing immune cells and inflammatory mediators.
    • Autoimmune diseases occur when the immune system attacks healthy tissues, causing inflammation and tissue damage.

    Inflammation in Different Systems

    • Asthma: Inflammation causes airway constriction and increased mucus production, making it difficult to breathe.
    • Gastrointestinal Disorders: Examples include Crohn's disease, ulcerative colitis, appendicitis, and cholecystitis. Inflammation causes abdominal pain, tenderness, nausea, and vomiting.
    • Renal System: Inflammatory diseases like nephritis, lupus nephritis, and glomerulonephritis affect the kidneys and can occur at any age.

    Immunity

    • The immune system can sometimes attack the body's own tissues, causing inflammation.
    • Be aware of signs of anaphylaxis which include hives, itching, skin color changes, airway constriction, weak and rapid pulse, nausea, and dizziness.
    • Patients may experience joint pain, stiffness, fatigue, and shortness of breath.
    • Monitor the patient's mental state (mentation), airway patency, and existing allergies.
    • Anticipate the need for medications such as epinephrine, oxygen, antihistamines, corticosteroids, bronchodilators (beta-agonists), and pain relievers (analgesics).
    • Blood tests and further investigations may be needed to identify the cause of the immune response.

    Infection

    • Infections trigger inflammatory and immune responses, attracting white blood cells (WBCs) to the site of infection.
    • The body increases WBC production to fight the invading pathogen.
    • Be aware of symptoms like fever (hyperthermia), general discomfort (malaise), pain, pus discharge (purulent drainage), and excess sputum production.
    • Anticipate the need for blood tests (WBC count and differential, and serum albumin levels), and cultures to identify the infectious agent.
    • Treatment may include fever-reducing medications (antipyretics) and antibiotics (anti-infectives).

    Mood and Affect

    • Corticosteroids commonly prescribed for inflammatory conditions may trigger mood changes, such as euphoria, depression, or severe mental instability.
    • Monitor patients for mood swings or unusual changes in mood.
    • Educate caregivers to promptly report any significant mood changes or unusual behavior observed in patients.

    Immunity

    • The body can have an abnormal immune response, where the body perceives normal tissue as foreign and attacks it.
    • Inflammation becomes uncontrollable in this situation.
    • Anaphylaxis is a serious, potentially life-threatening allergic reaction.
    • Symptoms include hives, itching, skin color changes, airway constriction, weak and rapid pulse, nausea, and dizziness.
    • Patient may present with joint pain and stiffness, fatigue, and shortness of breath.
    • Assess for mental status, airway patency, and known allergies.
    • Anticipate administration of epinephrine, oxygen, antihistamines, cortisone, beta-agonists, and analgesics, along with blood tests to identify the cause.

    Infection

    • Pathogens trigger inflammatory and immune responses, attracting white blood cells (WBCs) to the area.
    • Increased WBC production occurs to destroy the invading pathogen.
    • Watch for signs of hyperthermia, malaise, pain, purulent drainage, and excessive sputum production.
    • Anticipate blood tests for WBC count and differential, cultures, and serum albumin.
    • Treatment may include antipyretics (fever reducers) and anti-infectives.

    Mood and Affect

    • Corticosteroids used to treat inflammation can cause mood changes, including euphoria, depression, and severe mental instability.
    • Be alert for mood swings or unusual changes in mood.
    • Educate caregivers to promptly report any significant mood changes.

    Asthma

    • Exposure to allergens or infections like bronchitis or pneumonia causes inflammation in the airways.
    • Inflammation leads to airway swelling, bronchoconstriction, and increased mucus production.
    • Patients experience symptoms like coughing, wheezing, difficulty breathing, and chest tightness.

    Oxygenation

    • Monitor for signs of inadequate oxygenation, including cyanosis, abnormal blood gas readings, labored breathing, unusual lung sounds, and difficulty clearing mucus.
    • Prepare to administer medications such as epinephrine, bronchodilators, antihistamines, and corticosteroids.
    • Continuously monitor oxygen saturation using pulse oximetry.
    • Provide supplemental oxygen when necessary.
    • Pulmonary function testing can be used to assess airflow.

    Safety Considerations

    • Abruptly stopping corticosteroids can result in adrenal insufficiency and crisis.
    • Adrenal insufficiency can lead to severe low blood pressure, rapid heart rate, and other complications.
    • Explain the importance of gradually reducing corticosteroid dosage as prescribed by the healthcare provider.
    • Instruct patients to contact their healthcare provider if they are unable to take their medication for one day or longer due to illness.
    • Be vigilant for signs of adverse effects if medication is abruptly stopped.
