Case Presentation: The patient was incidentally found to have a renal mass on abdominal ultrasonography.

Anticoagulant therapies against sepsis-induced disseminated intravascular coagulation.

Disseminated intravascular coagulation (DIC) is a frequent but lethal complication in sepsis. Anticoagulant therapies, such as heparin, antithrombin, activated protein C, and recombinant human-soluble thrombomodulin, were expected to regulate the progression of coagulopathy in sepsis. Although a number of randomized controlled trials (RCTs) have evaluated the survival effects of these therapies over the past few decades, there remains no consistent evidence showing a significant survival benefit of anticoagulant therapies.
