Anti-cytokine strategies in acute pancreatitis: pathophysiological insights and clinical implications.
The clinical presentation of acute pancreatitis varies significantly from mild self-limiting discomfort to a severe life-threatening condition. Once the disease process is initiated, the severity of the disease is largely determined by a complex network of activated inflammatory mediators such as cytokines, proteolytic enzymes, reactive oxygen species, and many more which render the local injury to a systemic disease with multiple organ dysfunction, sepsis, and considerable mortality. Remarkable progress in diagnostic modalities, intensive care technologies, and organ preserving surgical techniques have decreased mortality of severe acute pancreatitis during the past decades. However, the treatment of acute pancreatitis still remains largely supportive and no specific approach exists to prevent evolving complications. A large body of clinical and experimental evidence suggests that cytokines are key factors in the pathomechanism of local and systemic complications of acute pancreatitis. Targeting cytokine activity as therapeutic approach to acute pancreatitis is a challenging concept and the results of modulating activation of TNF-alpha, IL-1beta, IL-2, IL-10, PAF and various chemokines has indeed been promising in the experimental setting even if tested under therapeutic conditions. However, experience from a limited number of clinical trials on anti cytokine strategies in acute pancreatitis has remarkably emphasized that translating successful experimental observations into reproducible clinical associations seems to be difficult.
