Plasma procalcitonin level as a predictor of treatment response in ICU patients with bacterial sepsis

Sepsis is one of the most important causes of mortality in severely ill ICU patients. At least, a part of high mortality rate in sepsis patients is due to less specific clinical symptoms for prompt diagnosis. Recently some studies report that serum levels of procalcitonin will increase in these patients but changes of serum levels following treatments is not known. This study was designed to determin procalcitonin levels in patients with bacterial infectious disease in ICU, initially and during therapy and compare the levels during response to treatment
