Flashcard 1: Are acute phase reactants produced by liver in acute or chronic inflammatory states?_____

Answer: Both

Flashcard 2: What class of acute phase reactant that when upregulated during chronic inflammation can lead to amyloidosis?_____

Answer: serum amyloid A proteins

Flashcard 3: Erythrocyte Sedimentation Rate _____ in inflammatory conditions

Answer: increases

Flashcard 4: What acute phase reactant is upregulated during inflammation to opsonize targets, fixing complement and facilitate phagocytosis?_____

Answer: C-reactive protein

Flashcard 5: Lymph node biopsy in cat scratch disease reveals _____ resembling those seen in lymphogranuloma venereum (LGV)

Answer: stellate granulomas

Extra: Cat scratch disease is caused by Bartonella henselae. Note: Do not confuse 'stellate granulomas' (necrotizing) with 'asteroid bodies' (stellate inclusions) seen in Sarcoidosis (non-caseating).
