  • Consideration of corticosteroids
  • Examination of gout

Inflammation

• Definition
  • Inflammation is a physical condition that occurs in response to injury or infection.
• Causes of Inflammation
  • Foreign body presence (bacteria, virus)
  • Injuries (e.g., sprains or strains)

Types of Inflammation

• Acute Inflammation
  • Definition: Short-term inflammation, typically resulting from injuries or immediate responses to harmful stimuli.
  • Examples: Sprains, strains, acute injuries
• Chronic Inflammation
  • Definition: Long-term inflammation that can lead to tissue damage, characterized by prolonged inflammatory response.
  • Examples: Arthritis (including osteoarthritis), Crohn's disease, lupus

Symptoms of Inflammation

• Common symptoms include:
  • H: Heat
  • I: Induration (hardness of the tissue at the injury site)
  • P: Pain
  • E: Edema (swelling)
  • R: Redness
• Alternative acronym: SHARP
  • S: Swelling
  • H: Heat
  • A: Altered movement
  • R: Redness
  • P: Pain

Assessing Inflammation

• Initial Assessment
  • Determine the cause of inflammation, e.g., cellulitis versus a sprained ankle
  • Example assessment: Splinter removal can lead to self-resolution without extensive medication

Treatment of Inflammation

• Immediate Treatment Options
  • R.I.C.E. Protocol:
  • R: Rest
  • I: Ice
  • C: Compression
  • E: Elevation

Anti-Inflammatory Medications

• NSAIDs (Nonsteroidal Anti-Inflammatory Drugs)
  • Common Examples: Ibuprofen (Motrin, Advil), Naproxen (Aleve), Diclofenac (Voltaren), Meloxicam (Mobic)
  • Mechanism of Action: Inhibit COX-1 and COX-2 enzymes which produce prostaglandins that mediate inflammation

Aspirin (Salicylates)

• Definition: Aspirin is a salicylic acid derivative used to reduce inflammation.
• Dosage Forms:
  • 81 mg (low-dose, referred to as 'baby aspirin' but not for children)
  • 325 mg (regular strength)
• Important Points:
  • Chewable and enteric-coated forms available
  • Strict regulations exist for usage, especially considering side effects

Risks Associated with NSAIDs

• Common Side Effects:
  • Gastrointestinal (GI) issues (ulcers, bleeding)
  • Kidney damage in high doses
  • Blood thinning properties leading to increased bleeding risk
• Maximum Dose for Ibuprofen:
  • Over-the-counter maximum: 1200 mg/day (equivalent to 6 pills of 200 mg each)
• Contraindications:
  • Patients with kidney impairment or peptic ulcers
  • Caution with patients on anticoagulants
  • Not approved for children younger than 6 months
  • Avoid use during pregnancy, especially during the third trimester

Monitoring Patients on NSAIDs

• What to Monitor:
  • Kidney function: BUN and creatinine levels
  • Signs of gastrointestinal bleeding: dark, tarry stools (melena), coffee-ground vomit, bruising
  • Blood sugar levels in patients with diabetes (especially if prescribed corticosteroids)

COX-2 Inhibitors

• Example: Celecoxib (Celebrex)
• Mechanism: Specifically inhibits COX-2 and is used for moderate to severe inflammation (e.g., arthritis)
• Risks:
  • Similar risks of gastrointestinal irritation and blood thinning, but at a lower severity compared to traditional NSAIDs
  • Increased risk for cardiovascular events

Corticosteroids

• Definition: Steroids ending in '-zone' (e.g., prednisone) reduce inflammation and modify immune responses.
• Effects on the Body:
  • Elevates blood sugar (hyperglycemia)
  • Causes fluid retention and weight gain
  • Can lead to hypocalcemia with long-term use (increased risk of osteoporosis)
  • Must be taken with food to mitigate GI irritation and prevent ulcers
  • Masks symptoms of infections, thus heightening the risk of undetected infections

Monitoring Patients on Corticosteroids

• Key Monitoring Parameters:
  • Blood glucose levels
  • Weight and signs of edema
  • GI bleeding indicators (e.g., blood in stools or vomit)
  • Signs and symptoms of infections
• Avoidance:
  • Patients with active infections or those on live vaccines should refrain from corticosteroids
  • Tapering is crucial; abrupt discontinuation can lead to adrenal crisis

Antipyretics

• Definition: Medications that reduce fever.
• Common Antipyretics:
  • Acetaminophen (Tylenol)
  • Aspirin, NSAIDs (e.g., ibuprofen)
• Important Notes:
  • Acetaminophen is not an NSAID and does not possess anti-inflammatory properties
  • Liver toxicity is a significant risk in overdose scenarios; maximum dosage often recommended at 3 grams per day
• Contraindications:
  • Patients with liver disease should not take acetaminophen
  • Caution advised for individuals consuming alcohol regularly

Gout

• Definition: A form of arthritis characterized by the buildup of uric acid in joints, commonly affecting the great toe.
• Symptoms: Hot, red, swollen joints, often severely painful.
• Triggers:
  • Alcohol, high-purine foods (red meat, seafood)

Treatment Options for Gout

• Acute Attack Management: Colchicine (dissolves uric acid), NSAIDs (e.g., indomethacin) or corticosteroids
• Preventative Medications:
  • Allopurinol (first-line treatment, inhibits uric acid formation)
  • Probenecid (increases uric acid excretion)
  • Rasburicase (converts uric acid to less toxic forms)

Monitoring and Patient Education for Gout

• Avoidance: High-purine foods for gout management
• Signs to Monitor: Rash as a common allergic response to allopurinol, and continuous liver and kidney monitoring during treatment.
• Antacids: Must not be taken simultaneously with allopurinol.

Conclusion

• Inflammation can be treated effectively with NSAIDs and corticosteroids; however, careful monitoring and an understanding of side effects and contraindications are essential for safe and effective treatment.
