Abstract
OBJECTIVE To study the literature data on pancreatogenic encephalopathy in patients with destructive pancreatitis. MATERIAL AND METHODS Searching for Russian- and English-language literature data was carried out in electronic databases: elibrary, PubMed, the Cochrane Library. We planned a systematic review if studies with evidence level 1 and 2 were available. If these trials were absent, descriptive review was considered. RESULTS No studies with evidence level 1 and 2 were found in available literature. Therefore, a descriptive review was carried out. Analysis of primary sources showed that the incidence of pancreatogenic encephalopathy is 9-35% and has no direct correlation with etiology of destructive pancreatitis. Major factors of pathogenesis are high serum enzymes, activation of proinflammatory cytokines and hypoxemia, which are accompanied by damage to myelin sheath of the white matter and cytotoxic brain edema. Clinical manifestation of pancreatogenic encephalopathy occurs within two weeks. Acute onset and various symptoms are typical. Possible laboratory predictors of encephalopathy are persistent hyperglycemia, increased hematocrit, fibrinogen-like protein 2 (FPB-2), proinflammatory cytokines TNF-αand interleukin-1-beta. Pancreatogenic encephalopathy is a factor of unfavorable prognosis of treatment. Mortality in patients with pancreatogenic encephalopathy is 57-70%. Favorable course of pancreatic necrosis is followed by regression of cerebral disorders in most cases while residual cognitive disorders are possible in elderly patients. CONCLUSION Pancreatogenic encephalopathy accompanies severe destructive pancreatitis. It is an unfavorable factor for treatment outcomes requiring further research.

RORγt inhibitor SR1001 alleviates acute pancreatitis by suppressing pancreatic IL-17-producing Th17 and γδ-T cells in mice with ceruletide-induced pancreatitis.

Abstract
The management of acute pancreatitis (AP) remains a challenge to clinicians worldwide for limited effective interventions. Retinoid orphan receptor gamma t (RORγt) is a therapeutic target for several diseases; however, it is unclear whether inhibiting RORγt can ameliorate AP. The relative expression of RORγt, IL‐17 and IL‐23 in the peripheral blood mononuclear cells of AP patients was measured by RT‐PCR. An AP mouse model was induced by ceruletide, and SR1001 was injected before ceruletide administration. RORγt+ cells, T helper 17 cells (Th17), regulatory T cells (Tregs) and γδ T cells were assessed in the pancreas and spleen by flow cytometry. Higher RORγt expression in patients indicated the potential role of RORγt in AP progression. Analyses of the IL‐17/IL‐23 axis confirmed its role. SR1001 significantly alleviated AP histologically in the mouse model. Serum levels of amylase, IL‐6, TNFalpha, IL‐17 and IL‐23 decreased upon SR1001 treatment. SR1001 selectively decreased the number of RORγt+, Th17, Tregs and γδ T cells in the pancreas but not the spleen. Collectively, these results showed that SR1001 exerted therapeutic effects on AP by suppressing IL‐17‐secreting Th17 and γδ T cells in the pancreas. Thus, SR1001 may be a promising drug for the treatment of AP in the clinic.
