Clinical aspects of diabetic ketoacidosis

Precipitating Factors for Diabetic Ketoacidosis among Patients with Type 1 Diabetes Mellitus: The Effect of Socioeconomic Status

<b><i>Background:</i></b> Diabetic ketoacidosis (DKA) is one of the life-threatening acute complications of diabetes mellitus that mainly occurs in type 1 diabetes mellitus (T1DM). This study aimed to determine the socioeconomic factors associated with DKA in patients with T1DM in Basrah. <b><i>Methods:</i></b> A cross-sectional study including patients with T1DM who were admitted due to DKA or any other complaint in any of the teaching hospitals in Basrah, from February to October 2017. Data collection from each patient or their parents using a questionnaire was designed to capture personal, social, and disease-related factors. <b><i>Results:</i></b> One hundred forty-seven patients were involved in this study. They were compared with different factors to assess correlations with the risk of DKA. Younger age, underweight, being without a job, low personal and/or mother educational level, travel, home glucose monitoring less than 7 times a week, uncontrolled HbA_1c and insulin stoppage as a cause of DKA regardless of the reasons to stop were associated with an increased risk of DKA. On the other hand, own home, availability of a glucometer for checking glucose, basal-bolus insulin regimen, insulin supply, and education at a tertiary center, correct injection technique whoever injected the insulin and dietary adherence, all were associated with a decreased risk of DKA. Other factors like gender, marital status, smoking status, father educational level, residency, income, personal home area, the frequency of HbA_1c checking, and family history of diabetes were not associated with a significant effect on the DKA risk. <b><i>Conclusions:</i></b> Multiple socioeconomic factors interact to play a vital role in the development of DKA among patients with T1DM in Basrah.

Guidelines for Perioperative Management of the Diabetic Patient

Management of glycemic levels in the perioperative setting is critical, especially in diabetic patients. The effects of surgical stress and anesthesia have unique effects on blood glucose levels, which should be taken into consideration to maintain optimum glycemic control. Each stage of surgery presents unique challenges in keeping glucose levels within target range. Additionally, there are special operative conditions that require distinctive glucose management protocols. Interestingly, the literature still does not report a consensus perioperative glucose management strategy for diabetic patients. We hope to outline the most important factors required in formulating a perioperative diabetic regimen, while still allowing for specific adjustments using prudent clinical judgment. Overall, through careful glycemic management in perioperative patients, we may reduce morbidity and mortality and improve surgical outcomes.

Adult hyperglycemic crisis: a review and perspective

Hyperglycemic crisis, which includes Diabetic Ketoacidosis and Hyperglycemic Hyperosmolar State, is a common diagnosis in high acuity hospital units and admission rates continue to increase despite preventive strategies. While diabetic ketoacidosis remains a common cause of death in children and adolescents with type 1 diabetes, in adults reported mortality is variable and depends on the severity of metabolic derangement and the presence of other acute and chronic conditions. Hyperosmolar hyperglycemic state, and the overlap syndrome of hyperosmolar ketoacidosis, have a higher overall mortality though outcomes are improving. We discuss the diagnosis, epidemiology, and management strategies with particular reference to commonly encountered pitfalls in care and provide an updated perspective on the shifts in the epidemiology and novel management strategies for these important disorders.

Management of the patient with diabetes in the perioperative period

With the ever-increasing number of patients with diabetes undergoing surgical procedures, effective perioperative management of diabetes mellitus has become progressively more important. In this review we discuss a number of strategic approaches to improve perioperative management, where the fine balance between aggressive blood glucose management and prevention of hypoglycaemia must be considered. We also discuss complications of diabetes mellitus, particularly where these directly compromise patient health and interventional outcomes.

Perioperative glucose control in the diabetic or nondiabetic patient

Patients with diabetes are more likely to undergo surgery than nondiabetics, and maintaining glycemic control in subjects with diabetes can be challenging during the perioperative period. Surgery in diabetic patients is associated with longer hospital stay, higher health care resource utilization, and greater perioperative mortality. In addition, several observational and interventional studies have indicated that hyperglycemia is associated with adverse clinical outcomes in surgical and critically ill patients. This paper reviews the pathophysiology of hyperglycemia during trauma and surgical stress and will provide practical recommendations for the preoperative, intraoperative, and postoperative care of diabetic patients.

Diabetic ketoacidosis complicated by axillary vein thrombosis

A case is presented of a 39-year-old male with Down's Syndrome, who also had type 1 diabetes of 22 years duration. He presented with diabetic ketoacidosis (DKA)-arterial blood pH 7.17, plasma bicarbonate 13.6mmol/l, plasma glucose 26.4mmol/l and urine heavily positive for ketones. He recovered with standard intravenous fluid and insulin treatment, but on the third day of admission developed a swollen left arm (which had not been used for intravenous cannulation). Doppler ultrasound confirmed a left axillary vein thrombosis. This slowly resolved with anticoagulation. Review of the available literature revealed that though arterial thrombosis is a common complication of DKA, venous thromboembolism is surprisingly rare, and there appear to be no previous specific reports of axillary vein thrombosis complicating DKA.

Hematologic complications of diabetes mellitus

In summary, hematologic abnormalities in diabetes affect the function, morphology, and metabolism of blood cells, and the coagulation system. These complications can contribute to the development of anemia, infection, and hypercoagulability in diabetic dogs and cats. Some hematologic changes, such as glycosylated hemoglobin and fructosamine, play an important role as markers of glycemic control. Hematologic changes also serve as important models for changes occurring in other tissues, such as cataract formation and nephropathy. Further study of blood alterations will enhance our knowledge of the biochemistry and pathophysiology of diabetes and diabetic complications and stimulate the development of effective preventative and therapeutic measures.

Resource utilization in treatment of diabetic ketoacidosis in adults

This study defines determinants of cost of treatment of diabetic ketoacidosis. A chart review for 92 cases of ketoacidosis from 1988 to 1992 in 40 females and 25 males (age range 18 to 81) showed a length of stay of 5.7 +/- 4.9 d. Length of stay did not correlate with the level of nursing care or any other component of the initial order set. Length of stay was shorter in cases managed by diabetologists. Length of stay was inversely proportional to the interval from arrival to the first shot of intermediate or long-acting insulin. Length of stay was longer in subjects with a positive bacterial culture (mean, 9.1 d) and was longer in subjects who arrived in the evening. There was a female predominance in total and recurrent cases of ketoacidosis. Female patients received fewer educational sessions than males. The grade of acidosis affected the duration of acidemia, but the grade of acidosis, APACHE scores, and admission lab values did not correlate with length of stay. The use of an intensive care unit (ICU) included more testing and expense without uniform clear benefit. Optimal transition from intensive to routine management includes resumption of long-acting insulins as soon as possible. Optimization of hospital care and reduction of incidence of ketoacidosis in females would have a marked effect on health care costs.
