Morphological examinations of 72 autopsy observations of the disseminated intravascular blood coagulation (DIVBC) syndrome (a combination of microthrombosis in renal glomeruli, adrenals, gastrointestinal tract and other organs with the hemorrhagic syndrome) led to a conclusion on the role of DIVBC in the formation of cortical renal necroses. All the observations presented capillary thrombosis of the renal glomeruli the extent and dissemination of which had influenced the size of cortical necroses. Cortical ischemia in early stages is manifested by nephrothelium dystrophy followed at 3-5 days by the development of necrosis of the tubules, glomeruli, and stroma. The formed cortical necroses of the kidneys (CNK) are demarkated, their healing occurs at the expense of the interstitial tissue, whose cells proliferate, and later collagen genesis is observed. Scars from CNK have been shown to contain tubules with an undifferentiated epithelium.

Disseminated intravascular coagulation (DIC) is a hematological disorder characterized by the abnormal activation of the coagulation system, which leads to widespread clotting and subsequent consumption coagulopathy. DIC is often associated with the progression of prostate cancer and can be a life-threatening condition. In this case report, we present a patient with recurrent DIC in the setting of advanced prostate cancer.

We tested the hypothesis that disseminated intravascular coagulation (DIC) predicts a poor prognosis in patients with out-of-hospital cardiac arrest (OHCA) treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Fifty-seven patients with cardiogenic OHCA who immediately underwent VA-ECMO upon admission to the emergency department were divided into 27 non-DIC and 30 DIC patients. DIC scores were calculated on admission and 24 h later (day 1).

Background: Disseminated intravascular coagulation (DIC) is a potentially fatal condition which is always secondary to an underlying disorder with abruption being the most common cause in obstetrics.Our study analysed the modified International Society of Thrombosis and Haemostasis DIC score for prediction of DIC in cases of abruptio placentae. Additionally, we correlated the score with severity of abruption to optimize its use in limited resource settings.

Snakebite is a neglected public health problem in tropical countries. Snakebite envenomation-associated acute kidney injury (SBE-AKI) is a major complication accounting for significant morbidity and mortality. The pathogenesis of SBE-AKI may be multifactorial, including prerenal AKI secondary to hemodynamic alterations, intrinsic renal injury, immune-related mechanisms, venom-induced consumptive coagulopathy and capillary leak syndrome.
