Abstract

BACKGROUND: Proinflammatory cytokines play a fundamental role in the local and systemic inflammatory responses in the initial stages of acute biliary pancreatitis (ABP) and in the development of severe forms of the disease.

OBJECTIVES: The aim of the present study was to assess the systemic release of proinflammatory cytokines and to characterize differences between patients with mild ABP (MABP) and severe ABP (SABP)

PATIENTS AND METHODS: In the current study, 54 patients with MABP were compared with 14 patients with SABP. Serum levels of tumour necrosis factor-alpha, interleukin (IL)-1ß, IL-6, IL-8 and IL-12p40 were measured every second day after admission for one week.

RESULTS: The tumour necrosis factor-alpha level was similar in all days of analysis in patients with MABP but was lower compared with SABP patients. The level of IL-1ß was higher at admission in patients with MABP. The level of IL-6 peaked on admission day in both groups, but in patients with SABP, the obtained values were higher. The level of IL-8 on admission day was slightly higher in patients with MABP and systematically decreased when measured on the following days (the third, fifth and seventh days of the study). An increased level of IL-8 during the third, fifth and seventh days of the investigation was seen in SABP patients. The level of IL-12p40 was slightly higher in patients with MABP on the day of admission.

CONCLUSIONS: The levels of some proinflammatory cytokines are higher in patients with SABP than in patients with MABP. The most consistent difference between the two groups was that the levels of IL-6 were significantly higher in patients with SABP throughout the study. Serum concentration of IL-6 may be helpful as a marker of severity and outcome of ABP.
