Which of the following is included among the PINI inflammatory response markers?

• A. Alpha-1 acid glycoprotein
• B. Interleukin-2
• C. Platelet count
• D. Fibrinogen

Answer: (A)

PINI uses specific acute-phase proteins to gauge inflammatory status, with alpha-1-acid glycoprotein being one of the key markers. AGP rises in response to inflammation and tends to stay elevated longer, providing a useful signal of persistent inflammatory burden that affects nutritional status and prognosis in patients on nutrition support. Interleukin-2 is a cytokine involved in immune signaling, not a component of PINI. Platelet count and fibrinogen are inflammatory indicators in general, but they are not part of the standard PINI inflammatory marker set. So, alpha-1-acid glycoprotein is the marker included in PINI.
