The Sugiura procedure (SP) was performed upon 27 patients with hemorrhagic portal hypertension secondary to extrahepatic portal vein thrombosis (EPVT) without associated hepatic disease. There were 14 female and 13 male patients. The mean age was 28 +/- 14 years. The causes of EPVT were protein C deficiency in two; antithrombin III deficiency in one patient, a history of omphalitis in two patients, a history of pancreatitis in one patient and idiopathy in 21 patients. The SP was completed in two surgical stages in 14 patients and in one stage in nine. There was one operative death. One patient had mild postoperative encephalopathy, and two patients rebled at long term follow-up study. Actuarial survival rate was 82 per cent at five and ten years. It is concluded that the SP is a good alternative for the management of hemorrhagic portal hypertension secondary to EPVT.

The Sugiura Procedure (SP) was performed in 27 patients with hemorrhagic portal hypertension secondary to extrahepatic portal vein thrombosis without associated liver disease (EPVT). There were fourteen females and 13 males. Mean age was 28 +/- 14 years. The causes of EPVT were: protein C deficiency-2 cases, antithrombin III deficiency-1 case, omphalitis history-2 cases, pancreatitis history-1 case and idiopathic-21 cases. The SP was completed with two surgical stages in 14 patients and with one operation in nine. There was one operative death. One patient developed mild postoperative encephalopathy, and two patients re-bled at long-term. Actuarial survival was 82% at five and ten years. It is concluded that the SP is a good alternative for the management of hemorrhagic portal hypertension secondary to EPVT.

Inter-alpha-trypsin inhibitor (ITI) is a serine protease inhibitor found in human plasma. Its antiprotease activity is due to bikunin which is effective in various types of experimental shock and pancreatitis. Therefore ITI, which releases bikunin by proteolytic cleavage, could be of therapeutic interest. A method for the large-scale isolation of ITI from human plasma is described. ITI was purified from the prothrombin complex concentrate (PCC) by diethylaminoethyl-Sepharose fast-flow chromatography followed by a chromatographic step on immobilized heparin designed to remove C4, factor X and protein C. With this procedure, which was performed under mild conditions, a homogeneous preparation of native ITI was obtained, as demonstrated by electrophoretic and chromatographic analyses. ITI maintained its biological activity, as exhibited by its specific antitryptic activity of 420 +/- 65 IU/g. In order to decrease or eliminate the risk of transmission of viral disease due to lipid-enveloped viruses, the process incorporated a solvent-detergent treatment. Animal studies on the final product revealed no adverse side-effects in terms of toxicity, thrombogenicity or hypotension. This preparation appears suitable for therapeutic evaluation in animal experimental models.

Intravascular coagulation of the intraosseous microcirculation (capillaries and venous sinusoids) progressing to generalized venous thrombosis, and less commonly retrograde arterial occlusion, now appears to be the cause of nontraumatic osteonecrosis. However, this coagulopathy is only an intermediary event, which is always activated by some underlying etiologic risk factor(s). Conditions capable of triggering intravascular coagulation include familial thrombophilia (resistance to activated protein C, decreased protein C, protein S, or antithrombin III), hyperlipemia and embolic lipid (alcoholism and hypercortisonism), hypersensitivity reactions (allograft organ rejection, immune complexes, and antiphospholipid antibodies), bacterial endotoxic (Shwartzman) reactions and various viral infections, proteolytic enzymes (pancreatitis), tissue factor release (inflammatory bowel disease, malignancies, neurotrauma, and pregnancy), and other prothrombotic and hypofibrinolytic conditions.

Certain fractures and/or dislocations of the femoral head are known to cause arterial injury and result in post-traumatic osteonecrosis. However, the more complex etiology of non-traumatic osteonecrosis is multifactorial and includes chemotherapy, radiotherapy, thermal injuries, and especially coagulopathies, which are now commonly observed in these patients. Intravascular coagulation with fibrin thrombosis begins in the capillaries and sinusoids of the intraosseous microcirculation, and residual venous thrombosis is more likely to occur if there is coexistent hypofibrinolysis. Coagulopathies are intermediary events, which are always activated by some underlying etiologic risk factor(s). Conditions capable of triggering intravascular coagulation include familial thrombophilia (resistance to activated protein C, decreased protein C, protein S, or antithrombin III, and hyperhomocystinemia), hyperlipemia and embolic lipid (alcoholism and hypercortisonism), hypersensitivity reactions (allograft organ rejection, immune complexes, and antiphospholipid antibodies), bacterial endotoxic (Shwartzman) reactions and various viral infections, proteolytic enzymes (pancreatitis), tissue factor release (inflammatory bowel disease, malignancies, neurotrauma, and pregnancy), and other thrombophilic and hypofibrinolytic disorders. Currently known risk factors for non-traumatic osteonecrosis of the femoral head are described briefly in this review article.

Mesenteric vein thrombosis is an uncommon manifestation of hypercoagulable states. A case is reported of superior mesenteric vein (SMV) thrombosis in a patient with pancreatitis and protein C deficiency. A discussion of SMV thrombosis identification, management, and outcomes is included. The patient presented with a significant history of alcohol abuse and constant, midepigastric abdominal pain associated with nausea and vomiting. Amylase and lipase were elevated, and the patient was treated for pancreatitis. His symptoms initially responded to intravenous fluid hydration, but soon his clinical picture worsened, with increased nausea and vomiting, abdominal pain, and distension. Contrasted computed tomography of the abdomen revealed SMV thrombosis. A hypercoagulable workup revealed protein C deficiency. After a 3-month course of oral anticoagulant therapy, the SMV thrombosis resolved.

Acute pancreatitis is a local inflammatory process that leads to a systemic inflammatory response in the majority of cases, and sometimes leads to multiple organ failure. It is obvious that coagulation and especially the protein C system are involved in this disease. The present commentary is related to a study in patients with pancreatitis with and without multiple organ failure in which protein C and activated protein C levels were studied. The protein C system and other studies analyzing (activated) protein C levels are discussed.

Activated protein C (APC), a plasma serine protease, is best known for its ability to inhibit blood clot formation. APC acts as an anticoagulant by degrading coagulation cofactors Va and VIIIa, thereby attenuating the coagulation cascade. Over the past 15 years, impressive research advances have provided novel insights into the diverse biological activities of this molecule. APC is now viewed not only as an anticoagulant but also as a signaling molecule that provides a pivotal link between the pathways of coagulation, inflammation, apoptosis, and vascular permeability. The protective effect of APC supplementation in patients with severe sepsis likely reflects the ability of APC to modulate multiple pathways implicated in sepsis pathophysiology. This review attempts to summarize key studies that support the therapeutic potential of APC in conditions beyond sepsis such as stroke, ischemia-reperfusion injury, lung injury, asthma, pancreatitis, wound healing, and angiogenesis. A comprehensive PUBMED literature review up to May 2006 was conducted.

Familial chylomicronemia syndrome is a group of rare genetic disorders characterized by deficient activity of an enzyme lipoprotein lipase or apo-protein C-II deficiency. In this paper we present an infant with massive hyperchylomicronemia and severe pancreatitis. Exchange transfusion for controlling hypertriglyceridemia and pancreatitis led to an increase in hyperviscosity which resulted in encephalopathy.

Severe acute pancreatitis (SAP) is characterized by an unregulated systemic proinflammatory response secondary to activation of trypsin within the pancreatic tissue, resulting in multiple organ failure. This dysregulated inflammation leading to organ dysfunction also characterizes severe sepsis. Activated protein C (APC) has pleotropic effects on the immune, coagulation, inflammatory and apoptotic pathways, and has been postulated to benefit acute pancreatitis--although concerns of possible retroperitoneal bleeding remain. Currently, experimental studies and subgroup data on patients with pancreatitis from a randomized controlled trial of APC in severe sepsis form the literature on the possible role of APC in SAP. We review the first randomized controlled trial of APC in acute pancreatitis published in the present issue of Critical Care.
