Simulated diabetic ketoacidosis therapy in vitro elicits brain cell swelling via sodium-hydrogen exchange and anion transport

Diabetic ketoacidosis (DKA) induced cerebral edema complicating small chronic subdural hematoma/hygroma/ at Zewuditu memorial hospital: a case report

BACKGROUND

While both DKA & CSDH/subdural hygroma/ are known to cause significant morbidity and mortality, there is no a study that shows the role & effect of DKA on CSDH/subdural hygroma/ & vice versa to authors' best knowledge; hence this work will show how important relation does exist between DKA & CSDH/ hygroma. This study highlights the diagnostic & management challenges seen for a case of a 44 years old female black Ethiopian woman admitted with a diagnosis of newly diagnosed type 1 DM with DKA + small CSDH/subdural hygroma/ after she presented with sever global headache and a 3 month history of lost to her work. She needed burrhole & evacuation for complete clinical improvement besides DKA's medical treatment.

CONCLUSION

DKA induced cerebral edema on the CSDH/subdural hematoma/ can have a role in altering any of the parameters (except the thickness of CSDH) for surgical indication of patients with a diagnosis of both CSDH +DM with DKA. Hence, the treating physicians should be vigilant of different parameters that suggests tight brain &/ cerebral edema (including midline shift, the status of cisterns, fissures & sulci) and should not be deceived of the thickness of the CSDH/subdural hygroma/alone; especially when there is a disproportionately tight brain for the degree of collection. Whether DKA induced cerebral edema causes a subdural hygroma is unknown and needs further study.

Brain injury in children with diabetic ketoacidosis: Review of the literature and a proposed pathophysiologic pathway for the development of cerebral edema

Cerebral edema (CE) is a potentially devastating complication of diabetic ketoacidosis (DKA) that almost exclusively occurs in children. Since its first description in 1936, numerous risk factors have been identified; however, there continues to be uncertainty concerning the mechanisms that lead to its development. Currently, the most widely accepted hypothesis posits that CE occurs as a result of ischemia-reperfusion injury, with inflammation and impaired cerebrovascular autoregulation contributing to its pathogenesis. The role of specific aspects of DKA treatment in the development of CE continues to be controversial. This review critically examines the literature on the pathophysiology of CE and attempts to categorize the findings by types of brain injury that contribute to its development: cytotoxic, vasogenic, and osmotic. Utilizing this scheme, we propose a multifactorial pathway for the development of CE in patients with DKA.

A Rare and Lethal Complication: Cerebral Edema in the Adult Patient with Diabetic Ketoacidosis

Commonly seen in the emergency department, diabetic ketoacidosis is a potentially lethal sequela of uncontrolled diabetes mellitus. In the adult population, a rare complication of diabetic ketoacidosis is cerebral edema. This case report discusses a 26-year-old male with new onset diabetes mellitus who developed cerebral edema leading to death.

The evolution of diabetic ketoacidosis: An update of its etiology, pathogenesis and management

The prognosis of diabetic ketoacidosis has undergone incredibly remarkable evolution since the discovery of insulin nearly a century ago. The incidence and economic burden of diabetic ketoacidosis have continued to rise but its mortality has decreased to less than 1% in good centers. Improved outcome is attributable to a better understanding of the pathophysiology of the disease and widespread application of treatment guidelines. In this review, we present the changes that have occurred over the years, highlighting the evidence behind the recommendations that have improved outcome. We begin with a discussion of the precipitants and pathogenesis of DKA as a prelude to understanding the rationale for the recommendations. A brief review of ketosis-prone type 2 diabetes, an update relating to the diagnosis of DKA and a future perspective are also provided.
