Taken together with other studies that sTREM-1 and sCD163 were elevated in patients with bilateral lung infiltrates caused by bacterial or fungal pneumonia [19] and more generally in sepsis [10] and the elevation is consistent with an invasive disease either from pneumonia or other causes of sepsis which can be due to fungal pneumonia as demonstrated in this study or bacterial pneumonia as demonstrated in humans [7, 20], both factors might serve as marker for CP diagnosis. Here, CD163 is linked to Sepsis.
