A Novel Algorithm for the Management of Inpatient COVID-19 Glucocorticoid-Induced Hyperglycemia.

Hyperglycemia in hospitalized patients with coronavirus disease 2019 (COVID-19) is linked to increased morbidity and mortality. This article reports on a novel insulin titration protocol for the management of glucocorticoid-induced hyperglycemia in hospitalized patients with COVID-19. Sixty-five patients with COVID-19 and glucocorticoid-induced hyperglycemia admitted after the protocol implementation were matched 1:1 to patients admitted before the treatment protocol rollout for analysis. In a large, diverse health system, the protocol achieved reductions in hypoglycemic events without increasing hyperglycemia or insulin use.

Cushing Disease Treated Successfully With Metyrapone During Pregnancy.

Background: Cushing disease (CD) during pregnancy is a rare but serious disease that adversely impacts maternal and fetal outcomes. As the sole use of metyrapone in the management of CD has been rarely reported, we describe our experience of using it to treat a pregnant patient with CD. Case Report: A 34-year-old woman with hypertension was diagnosed with adrenocorticotropic hormone-dependent CD on the basis of a urinary free cortisol (UFC) level of 290 µg/24 h (reference range, 6-42 µg/dL) and an abnormal dexamethasone suppression test (cortisol level, 12.4 µg/dL) before becoming pregnant. She conceived naturally 12 weeks after transsphenoidal surgery and was subsequently found to have persistent disease with a UFC level of 768 µg/dL. Surgery was deemed high-risk given the proximity of the tumor to the right carotid artery and the high likelihood of residual disease. Instead, she was managed with metyrapone throughout her pregnancy and titrated to a goal UFC level of <150 µg/24 h due to the known physiologic increase in the cortisol level during gestation. The patient had diet-controlled gestational diabetes and well-controlled hypertension. She gave birth to a healthy baby boy at 37 weeks of gestation, without adrenal insufficiency in the baby or her. Discussion: This case highlights the successful use of metyrapone throughout pregnancy to manage CD in patients in whom surgery is considered high-risk or in those with a low likelihood of cure. Although metyrapone is effective, close surveillance is required for worsening hypertension, hypokalemia, and potential adrenal insufficiency. Although no fetal adverse events have been reported, this medication crosses the placenta, and the long-term effects are unknown. Conclusion: We describe a case of CD during pregnancy that was successfully treated with metyrapone.

Mycophenolate Mofetil and Plasmapheresis: A Treatment Option for Severe Insulin Resistance caused by Insulin Antibodies.

OBJECTIVE: 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). METHODS: 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. RESULTS: 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%. CONCLUSION: 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.

Emerging technologies for the management of type 2 diabetes mellitus.

Diabetes mellitus is a global health problem affecting 422 million people worldwide, of which 34.2 million live in the United States alone. Complications due to diabetes can lead to considerable morbidity and mortality related to both microvascular and macrovascular disease. While glycosylated hemoglobin testing is the standard test utilized to evaluate glycemic control, emerging targets like "time in range" and "glycemic variability" often provide more accurate assessments of glycemic fluctuations and have implications for diabetes complications and quality of life. Patients with diabetes face considerable burdens of self-care including frequent glucose monitoring, multiple insulin injections, dietary management, and the need to track daily activities, all of which lead to reduced adherence and psychological burnout. From the provider perspective, limited patient data and access to self-management tools lead to treatment inertia and a reduced ability to help patients achieve and maintain their glycemic goals. In the past few decades, there have been considerable advances in treatment-based technology and technological applications designed to help reduce patient burden and provide tools for better self-management. These advances make real-time clinical data available for clinicians to make necessary changes in treatment regimens. In this review, we discuss the latest emerging technologies available for the management of people with type 2 diabetes mellitus.

Inequities in Diabetic Ketoacidosis Among Patients With Type 1 Diabetes and COVID-19: Data From 52 US Clinical Centers.

OBJECTIVE: We examined whether diabetic ketoacidosis (DKA), a serious complication of type 1 diabetes (T1D) was more prevalent among Non-Hispanic (NH) Black and Hispanic patients with T1D and laboratory-confirmed coronavirus disease 2019 (COVID-19) compared with NH Whites. METHOD: This is a cross-sectional study of patients with T1D and laboratory-confirmed COVID-19 from 52 clinical sites in the United States, data were collected from April to August 2020. We examined the distribution of patient factors and DKA events across NH White, NH Black, and Hispanic race/ethnicity groups. Multivariable logistic regression analysis was performed to examine the odds of DKA among NH Black and Hispanic patients with T1D as compared with NH White patients, adjusting for potential confounders, such as age, sex, insurance, and last glycated hemoglobin A1c (HbA1c) level. RESULTS: We included 180 patients with T1D and laboratory-confirmed COVID-19 in the analysis. Forty-four percent (n = 79) were NH White, 31% (n = 55) NH Black, 26% (n = 46) Hispanic. NH Blacks and Hispanics had higher median HbA1c than Whites (%-points [IQR]: 11.7 [4.7], P < 0.001, and 9.7 [3.1] vs 8.3 [2.4], P = 0.01, respectively). We found that more NH Black and Hispanic presented with DKA compared to Whites (55% and 33% vs 13%, P < 0.001 and P = 0.008, respectively). After adjusting for potential confounders, NH Black patients continued to have greater odds of presenting with DKA compared with NH Whites (OR [95% CI]: 3.7 [1.4, 10.6]). CONCLUSION: We found that among T1D patients with COVID-19 infection, NH Black patients were more likely to present in DKA compared with NH White patients. Our findings demonstrate additional risk among NH Black patients with T1D and COVID-19.
