Diabetic ketoacidosis

Diabetic ketoacidosis (DKA) is the most common acute hyperglycaemic emergency in people with diabetes mellitus. A diagnosis of DKA is confirmed when all of the three criteria are present — ‘D’, either elevated blood glucose levels or a family history of diabetes mellitus; ‘K’, the presence of high urinary or blood ketoacids; and ‘A’, a high anion gap metabolic acidosis. Early diagnosis and management are paramount to improve patient outcomes. The mainstays of treatment include restoration of circulating volume, insulin therapy, electrolyte replacement and treatment of any underlying precipitating event. Without optimal treatment, DKA remains a condition with appreciable, although largely preventable, morbidity and mortality. In this Primer, we discuss the epidemiology, pathogenesis, risk factors and diagnosis of DKA and provide practical recommendations for the management of DKA in adults and children

Perioperative Management of Hyperglycemia and Diabetes in Cardiac Surgery Patients

Perioperative hyperglycemia is common after cardiac surgery, reported in 60% to 90% of patients with diabetes and in approximately 60% of patients without history of diabetes. Many observational and prospective randomized trials in critically-ill cardiac surgery patients support a strong association between hyperglycemia and poor clinical outcome. Despite ongoing debate about the optimal glucose target, there is strong agreement that improved glycemic control reduces perioperative complications

Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic State

Acute hyperglycemic emergencies are a common cause of diabetes-related hospitalization. Diabetes ketoacidosis (DKA) is typically seen in patients with type 1 diabetes, and hyperosmolar hyperglycemic state (HHS) is typically seen in patients with type 2 diabetes. Presentation of DKA is acute with polyuria, polydipsia, and abdominal symptoms and characterized by hyperglycemia, ketonemia, and anion gap metabolic acidosis. Presentation of HHS is subacute with symptoms similar to DKA followed by altered mental status and extremely high blood glucose levels with high plasma osmolarity. The common precipitating causes of acute hyperglycemic emergencies include medication nonadherence, infections, and ischemic events. The key to treatment, for both DKA and HHS, is rehydration, insulin therapy, and electrolyte management. With proper treatment, mortality from acute hyperglycemic emergencies has been going down, but the morbidity is still very high

Microbiome differences related to metformin intolerance among Black individuals with diabetes, a pilot cross-sectional study

Aims: Metformin is the broadly accepted the first-line medication for diabetes. Its use, however, is limited by gastrointestinal side effects present in approximately 25% of patients. This study aimed to better understand the interplay between metformin intolerance and gut microbiota among Black individuals with diabetes. Methods: We performed a cross-sectional study among 29 Black individuals living with diabetes with or without metformin intolerance. Participants with mean age 59±11, 58% female, were stratified into three groups: 1)intolerant: metformin intolerance in the past, not on metformin; 2)partially intolerant: mild to moderate gastrointestinal symptoms, currently taking metformin 3)tolerant: using metformin without symptoms. We collected and analyzed rectal swabs and analyzed microbiota composition using V3–V4 regions of the 16s rRNA. Results: Metformin intolerant subjects trended towards having greatest alpha diversity, followed by tolerant and partially tolerant (Intolerant:4.9; Tolerant:4.2; Partially tolerant:3.9). Mean difference in alpha diversity for intolerant versus partially tolerant was 1.0 (95% CI-0.1,2.1) and intolerant versus tolerant were 0.7 (95% CI -0.4,1.8). Conclusion: This was the first study to evaluate the role of microbiota and metformin intolerance among Black individuals. We report on differences in alpha diversity as well as microbiota composition

The relation of plasma homocysteine to radiographic knee osteoarthritis

SummaryObjectiveHomocysteine has been implicated in multiple diseases that involve changes in structural tissue. In vitro studies have found that it alters the structure of collagen cross-linking thus affecting stability and mineralization such as that occurring in bone tissue. In the present study we considered the possible relationship between plasma homocysteine levels and the development and progression of knee osteoarthritis (OA).MethodsThe study question was posed in 691 men and 966 women from the original and offspring cohorts of the Framingham Osteoarthritis Study. We divided individuals into three groups according to plasma homocysteine levels and compared their risk for the development of new and progression of existing OA. We adjusted for potential confounders including age, body mass index, weight change, and physical activity.ResultsIn the crude analysis, men in the middle homocysteine tertile were found to be at a greater risk than men in the lowest tertile for incident OA [odds ratios of 1.9 (1.1–3.5)]. This result persisted after adjusting for covariates [odds: 2.0, (1.1–3.8)]. No significant correlation was seen in women for the development of OA. In the evaluation of progression no significant trends were seen for both men and women.ConclusionsAlthough cellular and molecular studies of homocysteine-related pathophysiology suggest a possible correlation between plasma homocysteine levels and OA, the present clinical study did not conclusively demonstrate such an association. However, further research is needed to explore the role of homocysteine in specific aspects of OA etiopathogenesis

Clinical characteristics and outcomes of patients with end-stage renal disease hospitalized with diabetes ketoacidosis

INTRODUCTION: There is limited evidence to guide management in patients with end-stage renal disease (ESRD) on chronic hemodialysis admitted with diabetes ketoacidosis. Thus, we investigated the clinical characteristics and outcomes of patients with ESRD admitted with diabetic ketoacidosis (DKA). METHODS: In this observational study, we used International Classification of Diseases Ninth/Tenth Revision codes to identify adult (aged 18-80 years) patients admitted to Emory University Hospitals between 1 January 2006 and 31 December 2016. DKA and ESRD diagnoses were confirmed by reviewing medical records and by admission laboratory results. RESULTS: Among 307 patients with DKA meeting the inclusion and exclusion criteria, 22.1% (n: 68) had ESRD on hemodialysis and 77.9% (n: 239) had preserved renal function (estimated glomerular filtration rate >60 mL/min/1.73 m(2)). Compared with patients with preserved renal function, the admission blood glucose was higher (804.5±362.6 mg/dL vs 472.5±137.7 mg/dL) and the mean hemoglobin A1c was lower (9.6%±2.1 vs 12.0%±2.5) in patients with DKA and ESRD, both p<0.001. The rates of hypoglycemia <70 mg/dL (34% vs 14%, p=0.002) and <54 mg/dL (13% vs 5%, p=0.04) were higher in the ESRD group. During hospitalization, more patients with ESRD develop volume overload (28% vs 3%, p<0.001) and require mechanical ventilation (24% vs 3%, p=<0.001). There were no differences in hospital mortality (3% vs 0%, p=0.21), but length of stay (median 7.0 vs 3.0 days, p<0.001) was longer in the ESRD cohort. After adjusting for multiple covariates, patients with DKA and ESRD have higher odds of hypoglycemia (OR 3.3, 95% CI 1.51 to 7.21, p=0.003) and volume overload (OR 4.22, 95% CI 1.37 to 13.05, p=0.01) compared with patients with DKA with preserved renal function. CONCLUSIONS: Patients with DKA and ESRD on chronic hemodialysis had worse clinical outcomes including higher rates of hypoglycemia, volume overload, need for mechanical ventilation and longer length of stay, compared with patients with preserved kidney function

812-P: Tight vs. Standard Inpatient Glycemic Targets in Non–Critical Care Settings—A Propensity Scored–Matched Analysis of Insulin-Treated Patients with Type 2 Diabetes

Differing blood glucose (BG) targets are recommended by professional organizations in noncritical care settings. Previous Endocrine Society and ADA guidelines recommended a target BG of 70-140 and 140-180 mg/dl; however, the 2023 ADA Standards of Care recommends a target of 100-180 mg/dl. The lack of consensus is due to the lack of randomized clinical trials (RTC) to support a tight vs relaxed BG target. We performed a post-hoc analysis on 9 RCTs to assess hospital outcomes in non-critically ill insulin-treated subjects with T2D targeting BG 70-140 mg/dL vs. 140-180 mg/dL. Among 1446 patients, 640 were treated to a target of 70-140 mg/dl and 806 to a target of 140-180 mg/dL. Propensity score matching was used to reduce the bias including sex, HbA1c, and home insulin use, for a final count of 1,146 patients (573 subjects in each target group). Patients in the tight BG target group had lower mean BG (163.73±39.79 vs 170.15±39.94 mg/dL, p=0.004), less hyperglycemia (BG >180: 86% vs 92%, p=0.003; BG >240: 51% vs 62%, p200 mg/dL. Our results indicate that lower BG target of 70-140 mg/dl leads to lower mean daily BG, less severe hyperglycemia events, similar rates of hypoglycemia and glycemic variability, and lower length of stay and complication rates compared to a higher target of 140-180 mg/dl. RCTs are indicated to elucidate optimal glycemic targets in hospitalized patients with T2D. Disclosure J.Saling: None. A.L.Migdal: None. M.A.Urrutia: None. Z.Zabala: None. B.Moazzami: None.
