Background/aims: Authors analyzed the clinical value of procalcitonin quick test (PCT-Q; BRAHMS Diagnostica, GmbH, Berlin) in infected pancreas necrosis verified by guided fine-needle aspiration (FNA).
Methodology: In the prospective, controlled study data of 24 patients were evaluated. PCT-Q was performed in patients with necrosis--verified on computer tomography (CT scan)--and/or sepsis. If PCT-Q test was positive or septic complication (infected necrosis or abscess) developed, CT or ultrasound (US) guided fine-needle aspiration was performed with Gram staining and bacteriology. Positive FNA result was indication for surgery with repeated staining and bacteriology of the surgical specimen.
Results: Septic complications developed in 12 patients. Analyzing the results, fine-needle aspiration was more authentic with 92% sensitivity and 100% specificity, while sensitivity of PCT-Q test remained 75% and its specificity 83%. Comparing abscess with infected necrosis significantly higher procalcitonin values were detected in patients with necrosis.
Conclusions: These results show that PCT-Q test is a possible non-invasive method which can be used besides fine-needle aspiration. Elevated levels of procalcitonin (higher than 2ng/mL) clearly suggest infection, while lower values do not exclude the possibility of local sepsis.
