Ectopic pregnancy occurs in 1-2% of all pregnancies. The majority occur in the fallopian tube, requiring intervention in the form of methotrexate or surgery. Ruptured ectopic pregnancies can lead to hemodynamic instability, requiring immediate surgical intervention. In the case reported here, the patient presented in diabetic ketoacidosis with a pregnancy of unknown location. Upon further evaluation she was found to have a ruptured ectopic pregnancy and was taken to the operating room for surgical management. We discuss the rarity of these concurrent disorders, the pathophysiology behind stress-induced diabetic ketoacidosis, the effects of elevated glucose in peri-operative management, and the importance of multi-disciplinary approaches to urgent clinical decision-making.

A 38-year-old with Turner syndrome presented with acute myocardial infarction due to multivessel spontaneous coronary artery dissection (SCAD) complicated by left ventricular free wall rupture. Conservative management for SCAD was pursued. She underwent sutureless repair for an oozing-type left ventricular free wall rupture. SCAD has not been previously reported in Turner syndrome. (Level of Difficulty: Advanced.).

Several reports showed the likelihood of a relationship between COVID-19 infection and the onset and prognosis of diabetes mellitus (DM) of all types. A 73-year-old female patient who presented to the clinic with respiratory symptoms and was tested positive for COVID-19 and treated for the next three days. Despite having neither a known history of hyperglycemia nor a family history of diabetes, she was unconscious and suffering from polyuria and polydipsia when she was brought to the emergency department. Once her condition was successfully stabilized, she was sent home with COVID-19 medications and oral anti-diabetic therapy. After subsequent viral recovery and continued anti-diabetic medication, the patient was monitored for the following seven months. DM might be linked to the SARS-CoV-2 infection. Further research is necessary to prove a relationship between COVID-19 and newly-onset diabetes.

UNASSIGNED: The 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.
UNASSIGNED: A 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.
UNASSIGNED: The 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%.
UNASSIGNED: DKA complicating GDM is extremely infrequent, but it cannot be dismissed. Early recognition along with prompt and appropriate medical and obstetrical management is critical.

UNASSIGNED: Severe hypertriglyceridemia (SHTG; plasma triglycerides >1000 mg/dL) is a rare but serious complication in children who develop diabetic ketoacidosis (DKA) from uncontrolled or new-onset type 1 diabetes.
UNASSIGNED: We present the case of a severely malnourished 16-year-old with a 10-month history of presumed type 2 diabetes managed with lifestyle modifications and metformin, who presented with SHTG, acute pancreatitis, and DKA. On examination, there was no evidence of lipemia retinalis, cutaneous xanthomas, or xanthelasma. He was initially treated with an insulin infusion and intravenous fluids. Despite this treatment, his pancreatitis symptoms worseneed and lipase level increased, necessitating 2 courses of plasmapheresis that immediately resolved his symptoms and dramatically improved his clinical status. He was discharged on hospital day 5. During his hospital admission, islet cell antigen 512, insulin, glutamic acid decarboxylase 65, and zinc transporter 8 autoantibodies were positive in the presence of insulinopenia, consistent with type 1 diabetes.
UNASSIGNED: Hypertriglyceridemia and hypercholesterolemia did not recur during follow-up, suggesting that the underlying mechanism for SHTG was insulin deficiency.
UNASSIGNED: This report of SHTG, DKA, and pancreatitis in an adolescent highlights the safe, early initiation of plasmapheresis as an effective treatment. To our knowledge, plasmapheresis has rarely been used so early in the course of treatment for an adolescent with SHTG, DKA, and acute pancreatitis.

UNASSIGNED: Insulin antibody (IA)-mediated insulin resistance (IR) is a rare condition for which immunosuppressive regimens have been described. However, these raise the risk of infection, and the drugs may not be effectively metabolized in patients with liver disease. A 61-year old male with type 2 diabetes mellitus and antibody-mediated IR who required >800 units of daily insulin presented with acute decompensation of his preexisting cirrhosis from recurrent diabetic ketoacidosis. Laboratory tests confirmed an IA level of >625 μU/mL (reference: <5.0 μU/mL).
UNASSIGNED: Centrifugal plasmapheresis and mycophenolate mofetil (MMF) were used to treat the patient to achieve glycemic control. Continuous glucose monitoring was implemented to monitor glycemic control pre- and posttherapy. Laboratory evaluation included levels of IA, C-peptide, insulin-like growth factor-1, growth hormone, salivary cortisol, zinc transporter 8, glutamic acid decarboxylase 65-kilodalton isoform antibody, and islet-cell antibodies.
UNASSIGNED: We initiated MMF followed by 5 sessions of plasmapheresis, leading to an overall 77.3% reduction from pretherapy insulin requirements after 6 months without further episodes of diabetic ketoacidosis or infection. The cirrhosis stabilized, and there was an improvement in HbA1C from 8.7% (72 mmol/mol) to 6.6% (49 mmol/mol) and time in euglycemic range from 30% to 61%.
UNASSIGNED: This is the first report of MMF and centrifugal plasmapheresis use to mitigate the effects of IA-mediated IR in a patient with cirrhosis. We recommend further studies to determine the utility of this treatment to improve care for patients at high risk for IA-mediated IR.

UNASSIGNED: To create awareness among health care professionals and nurses regarding interference with point-of-care (POC) blood glucose (BG) meter by high-dose intravenous vitamin C and other potential substances. We report a case that probably resulted in the death of a patient from an erroneous interpretation of POC-BG readings due to interference from high-dose vitamin C.
UNASSIGNED: Retrospective case review.
UNASSIGNED: Our patient was admitted following a syncopal episode associated with an acute non-ST elevation myocardial infarction. She was found to have significant hyperglycemia with blood glucose >600 mg/dL on POC testing, associated with moderate ketoacidosis. She was treated with intravenous insulin as a case of diabetic ketoacidosis (DKA). She developed severe hypoglycemia, which was confirmed on a venous BG, and her condition was complicated by an apparent stroke-like state. The patient deteriorated and subsequently died. We found no report of vitamin C causing apparent DKA, as seen in our case.
UNASSIGNED: POC-BG monitoring is very commonly used in intensive care unit settings to monitor BG as they are minimally invasive, convenient, and quick. However, physicians and nurses need to be aware that certain substances can interfere with and alter POC-BG levels, leading to incorrect diagnosis of pseudohyperglycemia or pseudohypoglycemia. This may potentially lead to catastrophic consequences and result in increased morbidity and mortality in intensive care unit settings. The Food and Drug Administration advises against the use of POC-BG meters in critical settings, and they should never be used to diagnose DKA.

UNASSIGNED: The coronavirus disease 2019 (COVID-19) pandemic has introduced countless challenges to the medical field. Although pediatric patients have been reported to have lower rates of COVID-19 mortality, the presence of pre-existing conditions can heighten the severity of their clinical presentation. This report discusses the potential influence COVID-19 might have on diabetic ketoacidosis.
UNASSIGNED: Our patient, a 6-year-old girl with known type 1 diabetes, presented with acute onset of abnormal breathing and altered mental status. The day prior, she had 1 episode of emesis, diarrhea, and abdominal pain but no fever. She presented to an outside hospital and was reported to have agonal breathing with a Glasgow Coma Scale score of 8 (eyes open to pain, no verbal response to stimuli, and localized pain). She was promptly intubated, and the initial laboratory tests revealed severe diabetic ketoacidosis (DKA). A family member had COVID-19, and she also tested positive for COVID-19.
UNASSIGNED: Our patient\'s rapid progression and severity of illness require a discussion of how COVID-19 might affect diabetes and indicate opportunities for improving clinical practice in children with pre-existing diabetes. We discussed how COVID-19 might change the underlying pathophysiology of DKA and cause metabolic complications. Possible mechanisms include binding to angiotensin-converting enzyme 2 receptors and enabling a proinflammatory \"cytokine storm.\" Additionally, ketoacidosis and altered mental status have been present in patients with COVID-19 without diabetes, which might potentiate the symptoms in developing DKA.
UNASSIGNED: Prompt recognition of DKA is warranted, as caregivers may attribute the symptoms to COVID-19 rather than to DKA, resulting in an increased severity of illness on presentation with acute symptom onset, as described in this report.

UNASSIGNED: The main objective was to describe and review a unique case that presented with diabetic ketoacidosis, positive insulin autoantibodies (IAAbs, which are found in Hirata disease and are usually present with hypoglycemia), and laboratory findings characteristic of type B insulin resistance syndrome (TBIRS) and systemic lupus erythematosus. Confirmation of TBIRS was obtained in Germany as immunoassay for insulin receptor antibodies (IRAbs) is not available in the United States.
UNASSIGNED: A literature review on TBIRS and cases that present with IAAbs and IRAbs simultaneously was conducted.
UNASSIGNED: We found 6 cases presenting with hypoglycemia, both antibodies, and treatment attempts with various management approaches that were different from the proposed National Institutes of Health (NIH) protocol for TBIRS. Our case is distinct because of the demographic background, presentation with diabetic ketoacidosis, comparatively lower insulin requirement, and no significant hypoglycemic episodes in the third phase.
UNASSIGNED: We propose that access to IRAb immunoassays may be important for diagnosing milder cases of TBIRS, while IAAbs may provide prognostic and therapeutic insights. Despite completely different presentation from other TBIRS patients reviewed, we observed that the proposed NIH protocol consisting of dexamethasone, rituximab, and cyclophosphamide was successfully employed in our patient. Thus, we propose that our case and the findings regarding antibody testing and the NIH treatment regimen may assist clinicians with earlier recognition and effective management of milder cases of TBIRS.

UNASSIGNED: To report the first case of diabetic ketoacidosis (DKA) and its management in a patient with diet-controlled prediabetes and metastatic breast cancer treated with alpelisib, a PI3K (phosphatidylinosiotol-3-kinase) inhibitor.
UNASSIGNED: Literature on the topic is reviewed. The case is that of a 66-year-old female with diet-controlled prediabetes and metastatic breast carcinoma who had initiated alpelisib 2 weeks prior to being admitted for diabetic ketoacidosis.
UNASSIGNED: Admission laboratory examination revealed a blood sugar of 1137 mg/dL, an anion gap of 25, large ketones in urine, and positive acetone in serum. The HbA1c level was 9.4% (79 mmol/mol) on admission, which had been 6.3% (45 mmol/mol) seven months earlier. She was discharged on subcutaneous insulin and instructed to discontinue alpelisib. Alpelisib was restarted 2 days later, which exacerbated her hyperglycemia within 24 hours. In the following months, her hyperglycemia was successfully managed with insulin and a SGLT 2 inhibitor. Unfortunately, her breast cancer progressed, ultimately leading to discontinuation of alpelisib. Blood sugar levels returned to a nondiabetic range upon discontinuation of alpelisib, and she is currently off all antihyperglycemic agents.
UNASSIGNED: Although PI3KCA inhibitors remain a promising drug in patients with metastatic breast cancer who have not responded to previous treatment, patients must be closely monitored for adverse effects such as hyperglycemia. Hyperglycemia could be a potentially limiting side effect of alpelisib. The optimal management of hyperglycemia induced by alpelisib warrants further research.
