Elevated serum hyaluronic acid and interleukin-6 levels in patients with mushroom poisoning admitted to the emergency department

Objectives: To assess the possible use of hyaluronic acid (HA) and interleukin-6 (IL-6) together as a biochemical marker of liver damage in mushroom poisoning (MP). Methods: We prospectively studied patients with MP who were admitted to the emergency service, between April 2005 and April 2007, Samsun, Turkey. Twenty-seven patients with MP were included in the study. Serum HA and IL-6 levels of the patients were determined using enzyme-linked immunosorbent assay daily for a total of 3 days. Ten healthy adults were included in the study to serve as controls. The patients were divided into survivors, and non-survivors. Results: There was no significant difference between the patients and controls with respect to serum HA levels on admission (p 0.05). However, IL-6 levels on admission were significantly higher in the patients than the control group (p 0.01). Serum HA and IL-6 levels on admission, and the following days were significantly higher in non-surviving patients (n=5) than in surviving patients (n=22) (p 0.05). There was a significant correlation between HA and IL-6 (r=0.42, p 0.05) on admission. The HA concentration was also significantly correlated with aspartate aminotransferase, alanine aminotransferase, and creatinine levels during the observation period. Serum HA and IL-6 levels increased in non-surviving patients throughout the period of observation. Conclusion: Increased serum HA and IL-6 levels are associated with hepatic damage in acute MP. Hyaluronic acid may be a useful marker in the assessment of MP-induced acute liver failure in clinical practice
