Project description:Alpelisib is a phosphoinositol-3-kinase alpha catalytic subunit (PIK3CA) inhibitor used in patients with PIK3CA mutated breast cancer. The phosphatidylinositol 3-kinase (PI3K) pathway is responsible for activating protein kinase-B (AKT), and activated AKT promotes translation of glucose transporter 4 and glycogen synthesis in insulin-responsive tissues. Therefore, it is perhaps not surprising that hyperglycemia is the most common side effect of alpelisib, though diabetic ketoacidosis (DKA) appears to be a rare complication. This case describes the unique presentation of a patient with no prior history of diabetes who presented with DKA after starting alpelisib, and returned to euglycemia off of insulin just three days after stopping the drug suggesting that alpelisib can cause DKA in patients who did not previously have diabetes, and that the hyperglycemia is completely reversible upon discontinuation of the PIK3CA inhibitor and consequent restoration of the PI3K/AKT pathway.

Project description:Euglycemic diabetic ketoacidosis (EDKA) is a rare and serious adverse effect of sodium-glucose cotransporter 2 inhibitors (SGLT-2i). The diagnosis is challenging due to the rarity, nonspecific symptoms, and absence of the alarmingly high blood glucose levels, and thus, it could be initially missed resulting in delayed treatment. This is particularly important for sedated patients, as the absence of typical clinical signs and symptoms can obscure the diagnosis. We present the case of a patient with type 2 diabetes mellitus on empagliflozin who developed EDKA while sedated after coronary artery bypass grafting (CABG) despite stopping the medication 24 hours prior to surgery. We also summarize the current literature on EDKA after CABG. Physicians must be aware and maintain a high index of suspicion for the illness, especially in patients with T2DM taking SGLT-2i and undergoing a major operation such as CABG. Emergent treatment and multidisciplinary follow-up are needed to improve patient outcomes and mitigate complications. Physicians should also consider identifying the optimal time to discontinue SGLT-2i before major surgeries and possible ketone studies in such patients, especially those sedated following the surgery.

Project description:Albuminuria is significantly reduced following Roux-en-Y gastric bypass (RYGB) surgery, suggesting a renoprotective effect of the intervention. Herein, we assess the relative impact of RYGB and RYGB equivalent non-surgical weight loss and glycaemic improvement on glomerular injury and global renal transcriptomic responses in the Zucker diabetic fatty rat (ZDF) model of diabetic nephropathy. We coined the term "medical bypass" (MB) to describe the intensive diet and pharmacotherapy based non-surgical intervention Adult ZDF rats underwent sham surgery (n=15) or RYGB (n=9). Nine sham-operated rats were calorie restricted and received insulin, liraglutide, metformin, ramipril, rosuvastatin and fenofibrate for 2 months (MB). Zucker fa/+ rats acted as healthy controls throughout. Bodyweight, glycaemia, albuminuria and glomerular injury specifically podocyte number, density and ultrastructure were assessed at follow up. Renal transcriptomes were compared by RNA-seq. RYGB resulted in 20-30% weight loss, normalized glycaemia and albuminuria and reduced indices of glomerular injury, specifically podocyte injury (foot process effacement). RYGB equivalent outcomes were obtained on all parameters following MB.

Project description:BackgroundRoux-en-Y gastric bypass (RYGB) is a surgery with low rate complications. However, it is not exempt from them, and 1-6% suffer complications such as postoperative bleeding. Many intraoperative techniques have been evaluated to reduce postoperative bleeding, like the oversewing or reinforcement of the staple line. This study aims to evaluate the rate of postoperative bleeding in the oversewing of the staple line of the gastric remnant group versus the stapling only group.MethodsThis is a 2-center, case-control study. We randomly selected two groups who underwent RYGB or OAGB: group A (n = 225) with oversewing from 2019 to 2020 and group B (n = 225) with stapling only between the period of 2017-2018; both groups with similar demographic characteristics.ResultsThe overall mean age was 37.39 ± 9.6 years and mean BMI was 41.59 ± 8.6 kg/m2; the postoperative bleeding rate was significantly lower (p < 0,05) in patients with oversewing of the staple line of the gastric remnant. Operative time was shorter for the stapling only group and the difference between the mean operative time was 10.6 min.ConclusionsOversewing the staple line of the gastric remnant significantly reduces the incidence of postoperative bleeding regardless of BMI. Being a cost-effective technique compared to others available despite the increase in operating time.

Project description:Diabetic ketoacidosis (DKA) is an acute and major life-threatening complication of diabetes mellitus. Fluid resuscitation, insulin therapy, and electrolyte replacement are essential for DKA treatment. Rarely, life threatening allergic reactions might develop in a patient treated with insulin. If anaphylaxis develops after insulin, the DKA treatment options are restricted. A limited number of case reports have been reported in patients with severe anaphylactic reactions to human insulin who were then treated with synthetic insulin analogues. We present a case of a 45-year-old male patient with allergic reactions to human insulin. The patient was successfully treated with insulin aspart and hemodialysis.

Project description:ObjectivesTo characterize hemodynamic alterations occurring during diabetic ketoacidosis (DKA) in a large cohort of children and to identify clinical and biochemical factors associated with hypertension.Study designThis was a planned secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a randomized clinical trial of fluid resuscitation protocols for children in DKA. Hemodynamic data (heart rate, blood pressure) from children with DKA were assessed in comparison with normal values for age and sex. Multivariable statistical modeling was used to explore clinical and laboratory predictors of hypertension.ResultsAmong 1258 DKA episodes, hypertension was documented at presentation in 154 (12.2%) and developed during DKA treatment in an additional 196 (15.6%), resulting in a total of 350 DKA episodes (27.8%) in which hypertension occurred at some time. Factors associated with hypertension at presentation included more severe acidosis, (lower pH and lower pCO2), and stage 2 or 3 acute kidney injury. More severe acidosis and lower Glasgow Coma Scale scores were associated with hypertension occurring at any time during DKA treatment.ConclusionsDespite dehydration, hypertension occurs in a substantial number of children with DKA. Factors associated with hypertension include greater severity of acidosis, lower pCO2, and lower Glasgow Coma Scale scores during DKA treatment, suggesting that hypertension might be centrally mediated.

Project description:Background/objectiveThe prevalence of diabetic ketoacidosis (DKA) in gestational diabetes mellitus (GDM) is very low. We describe a patient with GDM in whom severe DKA with intrauterine fetal demise developed in the setting of nonadherence to therapy.Case reportA 33-year-old woman, G2P0010, with no preexisting diabetes mellitus (DM) presented at 30 weeks of gestation with acute-onset altered sensorium, nausea, and emesis. GDM was diagnosed at 15 weeks of gestation with a serum glucose level of 266 mg/dL (70-134 mg/dL) after 1-hour 50-gram glucose challenge test. Glycated hemoglobin (HbA1C) was 5.9% (41 mmol/mol) at the time of GMD diagnosis. Insulin was initiated at week 20 of gestation. On presentation, serum glucose level of 920 mg/dL (70-110 mg/dL), pH of 7.02 (7.32-7.43), anion gap level of 38 mmol (5-17 mmol), bicarbonate level of 5.0 mEq/L (22-29 mEq/L), and large serum ketones were found. Ultrasound showed intrauterine fetal demise. She received intravenous fluids and continuous insulin. Following the spontaneous delivery of a nonviable fetus, DKA was resolved. Negative antiglutamic acid decarboxylase, islet cell, and zinc transporter 8 antibodies, C-peptide level of 2.4 ng/dL (1.1-4.4 ng/dL), and HbA1C level of 9% (75 mmol/mol) were found. Inpatient management included basal-bolus and sliding scale insulin therapies. Metformin was added upon discharge 7 days after admission. The HbA1C levels were 5.3% (34 mmol/mol) and 5% (31 mmol/mol) at the 3- and 6-month follow-ups, respectively. Insulin was discontinued. Currently, the patient is on metformin and glucagon-like peptide 1 receptor agonist.DiscussionThe development of insulin resistance during pregnancy is driven by multiple factors. Approximately 1% to 2% of pregnant women with impaired glucose tolerance develop DKA; most cases occur in women with type 1 DM. The approximate incidence of DKA in GDM is 0.02%.ConclusionDKA complicating GDM is extremely infrequent, but it cannot be dismissed. Early recognition along with prompt and appropriate medical and obstetrical management is critical.
