A recent analysis (125) of 480 episodes of suspected LOS in 208 preterm infants below 32 weeks of gestational age showed that serum IL-6 and PCT levels (hazard ratios 2.28 and 2.91, respectively), but not CRP (hazard ratio 1.16), were associated with sepsis severity and mortality risk. The gene discussed is CALCA; the disease is Sepsis.
