Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are a class of antidiabetic medications that improve glycemic control via inhibiting the reabsorption of filtered glucose and are approved for use in type 2 diabetes (T2DM). These drugs have recently been associated with euglycemic diabetic ketoacidosis (DKA). An increasing number of cases of SGLT-2i-associated DKA have occurred in patients with T2DM. Herein, we describe five episodes of hyperglycemic DKA in four type 2 diabetes patients receiving SGLT-2i therapy...

Introduction: The routine and gold standard method to diagnose of acid - base disturbance is arterial blood gas (ABG) sampling. Capnography could be used to measure the end-tidal carbon dioxide (ETCO2) levels and ETco2 has a close correlation with the PaCo2. The aim of this study was comparison the ETco2 and arterial blood bicarbonate levels in patients with metabolic acidosis. Methods: In a descriptive-analytical study that performed in Emergency Department of Emam Reza Medical Research and Training Hospital of Tabriz on patients with metabolic acidosis, ETco2 level and blood bicarbonate levels in 262 patients were evaluated...

BACKGROUND Besides providing anesthesia for surgery, the anesthesiologist's role is to optimize the patient for surgery and for post-surgical recovery. This involves timely identification and treatment of medical comorbidities and abnormal laboratory values that could complicate the patient's perioperative course. There are several potential causes of anion and non-anion gap metabolic acidosis in surgical patients, most of which could profoundly affect a patient's surgical outcome. Thus, the presence of an acute acid-base disturbance requires a thorough workup, the results of which will influence the patient's anesthetic management...

This consensus- based S1 Guideline for perioperative infusion therapy in children is focused on safety and efficacy. The objective is to maintain or re-establish the child's normal physiological state (normovolemia, normal tissue perfusion, normal metabolic function, normal acid- base- electrolyte status). Therefore, the perioperative fasting times should be as short as possible to prevent patient discomfort, dehydration, and ketoacidosis. A physiologically composed balanced isotonic electrolyte solution (BS) with 1-2...

Diabetic ketoacidosis (DKA), a common cause of severe metabolic acidosis, remains a life-threatening condition due to complications of both the disease and its treatment. This Acid-Base and Electrolyte Teaching Case discusses DKA management, emphasizing complications of treatment. Because cerebral edema is the most common cause of mortality and morbidity, especially in children with DKA, we emphasize its pathophysiology and implications for therapy. The risk for cerebral edema may be minimized by avoiding a bolus of insulin, excessive saline resuscitation, and a decrease in effective plasma osmolality early in treatment...

Maple Syrup Urine Disease (MSUD) is an inherited disorder caused by the dysfunction in the branched chain keto-acid dehydrogenase (BCKDH) enzyme. This leads to buildup of branched-chain keto-acids (BCKA) and branched-chain amino acids (BCAA) in body fluids (e.g. keto-isocaproic acid from the BCAA leucine), leading to numerous clinical features including a less understood skeletal muscle dysfunction in patients. KIC is an inhibitor of mitochondrial function at disease relevant concentrations. A murine model of intermediate MSUD (iMSUD) shows significant skeletal muscle dysfunction as by judged decreased muscle fiber diameter...

CONTEXT AND OBJECTIVE: Diabetic ketoacidosis (DKA) is associated with a metabolic alkalosis, which is thought to be due to vomiting. However, alkalosis can occur in DKA without vomiting. We retrospectively reviewed the acid-base disturbances in DKA admissions without vomiting. PARTICIPANTS AND METHODS: We included admissions of the patients with blood glucose and beta-hydroxybutyrate (βOHB) levels > 250 mg/dL and > 1.0 mmol/L, respectively. Admissions without vomiting were classified into a group with a βOHB > 3...

OBJECTIVE: Patients with a chronic alcohol use disorder presenting to the ICU may be deficient in important vitamins and electrolytes and are often prescribed a "banana bag" as a reflexive standard of therapy. The difficulty of diagnosing Wernicke's encephalopathy in the critical care setting is reviewed. Furthermore, whether the contents and doses of micronutrients and electrolytes in standard banana bags meet the needs of critically ill patients with an alcohol use disorder is assessed based on available evidence...

Euglycemic Diabetic Ketoacidosis is an uncommon occurrence. It is caused by an interaction of existing and worsening acidosis due to nausea and vomiting by a precipitating illness. In this case, a Type I Diabetic patient initially presented with Diabetic Ketoacidosis (DKA) that eventually evolved into Euglycemic Ketoacidosis brought about by continuous nausea and vomiting. The case presented the complexity involved with Type I Diabetes in regards to glucose and energy metabolism and highlights the need for vigilance in monitoring acid/base balance in all diabetic patients who are ill and present with normal blood glucose level...

Ketoacidosis during pregnancy carries significant risk of intrauterine fetal demise, but little is known about the impact of ketoacids on the ovine fetus. We report a case series of maternal ketoacidosis in ewes. Maternal ketoacidosis may result in biochemical and acid-base fetal abnormalities associated with changes in feto-placental unit perfusion.

A 54-year-old white female with hypothyroidism presented with abdominal pain, nausea, vomiting, and diarrhea. She was found to have diabetic ketoacidosis (DKA) and admitted to our hospital for treatment. Laboratory workup revealed positive antiglutamic acid decarboxylase antibodies and subsequently she was diagnosed with latent onset autoimmune diabetes in adult (LADA). She was successfully treated with insulin with clinical and laboratory improvement. Diagnosis of LADA has been based on three criteria as given by The Immunology of Diabetes Society: (1) adult age of onset (>30 years of age); (2) presence of at least one circulating autoantibody (GADA/ICA/IAA/IA-2); and (3) initial insulin independence for the first six months...

Succinyl-CoA:3-ketoacid CoA transferase (SCOT) deficiency and mitochondrial acetoacetyl-CoA thiolase (beta-ketothiolase or T2) deficiency are classified as autosomal recessive disorders of ketone body utilization characterized by intermittent ketoacidosis. Patients with mutations retaining no residual activity on analysis of expression of mutant cDNA are designated as severe genotype, and patients with at least one mutation retaining significant residual activity, as mild genotype. Permanent ketosis is a pathognomonic characteristic of SCOT-deficient patients with severe genotype...

Real euglycemic diabetic ketoacidosis [DKA; blood glucose <200 mg/dL (11.1 mmol/L)] is rare, and long-lasting starvation conditions due to intervening diseases in type 1 diabetes mellitus patients may also cause it. Euglycemic DKA is also reported in insulin-dependent diabetics with depression, alcoholics, glycogen storage diseases, and chronic liver disease apart from pregnant cases. This case report is presented to emphasize the importance of evaluation of acid-base state, urine glucose, and ketone values at the application in all newly diagnosed type 1 diabetic patients with normal glucose levels by defining euglycemic DKA that resulted from long-lasting starvation during Ramadan fasting in a newly diagnosed 14-year-old male patient...

Ketone bodies including acetone are disease biomarkers for diabetes that sometimes causes severe ketoacidosis. The present study was undertaken to clarify the significance of exhaled acetone and plasma ketone bodies at bedside in a clinical setting. The oral glucose tolerance test (OGTT) was performed in 10 healthy Japanese volunteers (five females and five males). Exhaled breath acetone and volatile sulfide compounds (VSCs) in mouth air were measured simultaneously with blood sampling during the OGTT using a portable gas chromatograph equipped with an In2O3 thick-film type gas sensor and a VSC monitor...
