Which finding is commonly seen in patients with periodontal and cardiac infections?

  1. Decreased C-reactive protein
  2. Increased C-reactive protein
  3. Elevated interleukin-6 (IL-6)
  4. Elevated tumor necrosis factor-alpha (TNF-α)
Show answer and explanation

Correct answer: B. Increased C-reactive protein

  • A. INCORRECT. CRP rises with inflammation, it does not fall.
  • B. CORRECT. CRP is the classic acute-phase reactant elevated in both periodontal disease and cardiovascular inflammation, and it is the standard systemic marker linking the two.
  • C. INCORRECT. IL-6 does rise and drives CRP production, but CRP is the recognized measured marker for this association.
  • D. INCORRECT. TNF-α is elevated in inflammation but CRP is the standard answer for the perio-cardiac link.
