  1. This article was originally published here Endocrinol Diabetes Metab Case Rep. 2021 May 1;2021:EDM210038. doi: 10.1530/EDM-21-0038. Online ahead of print. ABSTRACT SUMMARY: In this case report, we describe the management of a patient who was admitted with an ectopic ACTH syndrome during the COVID pandemic with new-onset type 2 diabetes, neutrophilia and unexplained hypokalaemia. These three findings when combined should alert physicians to the potential presence of Cushing’s syndrome (CS). On admission, a quick diagnosis of CS was made based on clinical and biochemical features and the patient was treated urgently using high dose oral metyrapone thus allowing delays in surgery and rapidly improving the patient’s clinical condition. This resulted in the treatment of hyperglycaemia, hypokalaemia and hypertension reducing cardiovascular risk and likely risk for infection. Observing COVID-19 pandemic international guidelines to treat patients with CS has shown to be effective and offers endocrinologists an option to manage these patients adequately in difficult times. LEARNING POINTS: This case report highlights the importance of having a low threshold for suspicion and investigation for Cushing’s syndrome in a patient with neutrophilia and hypokalaemia, recently diagnosed with type 2 diabetes especially in someone with catabolic features of the disease irrespective of losing weight. It also supports the use of alternative methods of approaching the diagnosis and treatment of Cushing’s syndrome during a pandemic as indicated by international protocols designed specifically for managing this condition during Covid-19.

  2. High blood sugar or glucose, also called hyperglycemia, occurs when there is too much sugar in the blood. High blood sugar is the primary symptom that underlies diabetes, but it can also occur in people who don’t have type 1 or type 2 diabetes, either because of stress or trauma, or gradually as a result of certain chronic conditions. It is important to manage high blood sugar, even if you don’t have diabetes, because elevated blood glucose can delay your ability to heal, increase your risk of infections, and cause irreversible damage to your nerves, blood vessels, and organs, such as your eyes and kidneys. Blood vessel damage from high blood sugar also increases your risk of heart attack and stroke. Non-Diabetic Hyperglycemia and Prediabetes You are considered to have impaired glucose tolerance or prediabetes if you have a fasting glucose level between 100–125 mg/dL, and hyperglycemia if your fasting blood glucose level is greater than 125 mg/dL, or greater than 180 mg/dL one to two hours after eating. The body obtains glucose mainly through carbohydrate consumption, but also through the breakdown of glycogen to glucose—a process called glycogenolysis—or conversion of non-carbohydrate sources to glucose—called gluconeogenesis—that primarily occurs in the liver. While 50% to 80% of glucose is used by the brain, kidneys, and red blood cells for energy, the remaining supply of glucose is used to produce energy. It is stored as glycogen in the liver and muscles, and can be tapped into at a later time for energy or converted into fat tissue. In healthy people, blood glucose levels are regulated by the hormone insulin to stay at a steady level of 80–100 mg/dL. Insulin maintains steady blood sugar by increasing the uptake and storage of glucose and decreasing inflammatory proteins that raise blood sugar when there is an excess of glucose in the blood. Certain conditions can increase your blood glucose levels by impairing the ability of insulin to transport glucose out of the bloodstream. When this occurs, you develop hyperglycemia, which puts you at an increased risk of prediabetes, diabetes, and related complications. Common Causes Cushing’s Syndrome Cushing’s syndrome results from excess secretion of the adrenocorticotropic hormone, a hormone produced in the anterior portion of the pituitary gland that causes excess cortisol to be produced and released from the adrenal glands. Pituitary adenomas, or tumors of the pituitary gland, are the cause of Cushing’s syndrome in more than 70% of cases, while prolonged use of corticosteroid medication can also significantly increase the risk. People with Cushing’s syndrome are at an increased risk of developing impaired glucose tolerance and hyperglycemia as a result of increased levels of cortisol throughout the body. Cortisol is a hormone that counteracts the effects of insulin by blocking the uptake of glucose from the bloodstream, thereby increasing insulin resistance and maintaining high blood sugar levels. Elevated cortisol levels also partially decrease the release of insulin from where it is produced in the pancreas. Approximately 10% to 30% of people with Cushing’s syndrome will develop impaired glucose tolerance, while 40% to 45% will develop diabetes. Corticosteroid medication is often prescribed to decrease inflammation throughout the body, but can lead to the development of Cushing’s syndrome and hyperglycemia because it activates specific enzymes that increase the conversion of non-carbohydrate molecules into glucose (gluconeogenesis). Corticosteroids also disrupt pancreatic cell function by inhibiting cell signaling pathways involved in the release of insulin from the pancreas.

  3. Some of the latest research advancements in the field of endocrinology presented at the Endocrine Society's virtual ENDO 2021 meeting included quantifying diabetic ketoacidosis readmission rates, hyperglycemia as a severe COVID-19 predictor, and semaglutide as a weight loss therapy. Below are a few more research highlights: More Safety Data on Jatenzo In a study of 81 men with hypogonadism -- defined as a serum testosterone level below 300 ng/dL -- oral testosterone replacement therapy (Jatenzo) was both safe and effective in a manufacturer-sponsored study. After 24 months of oral therapy, testosterone concentration increased from an average baseline of 208.3 ng/dL to 470.1 ng/dL, with 84% of patients achieving a number in the eugonadal range. And importantly, the treatment also demonstrated liver safety, as there were no significant changes in liver function tests throughout the 2-year study -- including alanine aminotransferase (28.0 ± 12.3 to 26.6 ± 12.8 U/L), aspartate transaminase (21.8 ± 6.8 to 22.0 ± 8.2 U/L), and bilirubin levels (0.58 ± 0.22 to 0.52 ± 0.19 mg/dL). Throughout the trial, only one participant had elevation of liver function tests. "Our study finds testosterone undecanoate is an effective oral therapy for men with low testosterone levels and has a safety profile consistent with other approved testosterone products, without the drawbacks of non-oral modes of administration," said lead study author Ronald Swerdloff, MD, of the Lundquist Research Institute in Torrance, California, in a statement. In addition, for many men with hypogonadism, "an oral option is preferred to avoid issues associated with other modes of administration, such as injection site pain or transference to partners and children," he said. "Before [testosterone undecanoate] was approved, the only orally approved testosterone supplemental therapy in the United States was methyltestosterone, which was known to be associated with significant chemical-driven liver damage." Oral testosterone undecanoate received FDA approval in March 2019 following a rocky review history. COVID-19 Risk With Adrenal Insufficiency Alarming new data suggested that children with adrenal insufficiency were more than 23 times more likely to die from COVID-19 than kids without this condition (relative risk 23.68, P<0.0001). This equated to 11 deaths out of 1,328 children with adrenal insufficiency compared with 215 deaths out of 609,788 children without this condition (0.828% vs 0.035%). These young patients with adrenal insufficiency also saw a much higher rate of sepsis (RR 21.68, P<0.0001) and endotracheal intubation with COVID-19 infection (RR 25.45, P<0.00001). Data for the analysis were drawn from the international TriNetX database, which included patient records of children ages 18 and younger diagnosed with COVID-19 from 60 healthcare organizations in 31 different countries. "It's really important that you take your hydrocortisone medications and start stress dosing as soon as you're sick," study author Manish Raisingani, MD, of the University of Arkansas for Medical Sciences and Arkansas Children's in Little Rock, explained during a press conference. "This will help prevent significant complications due to COVID-19 or any other infections. A lot of the complications that we see in kids with adrenal insufficiency are due to inadequate stress dosing of steroids." And with kids starting to return back to in-person schooling, "parents should also be reeducated about using the emergency injections of hydrocortisone," Raisingani added. He noted that the COVID-19 complication rates were likely so high in this patient population because many had secondary adrenal insufficiency due to being on long-term, chronic steroids. Many also had comorbid respiratory illnesses, as well. Cushing's Death Risk In a systematic review and meta-analysis of 87 studies -- including data on 17,276 patients with endogenous Cushing's syndrome -- researchers found that these patients face a much higher death rate than those without this condition. Overall, patients with endogenous Cushing's syndrome faced a nearly three times higher mortality ratio (standardized mortality ratio 2.91, 95% CI 2.41-3.68, I2=40.3%), with those with Cushing's disease found to have an even higher mortality risk (SMR 3.27, 95% CI 2.33-4.21, I2=55.6%). And those with adrenal Cushing's syndrome also saw an elevated death risk, although not as high as patients with the disease (SMR 1.62, 95% CI 0.08-3.16, I2=0.0%). The most common causes of mortality among these patients included cardiac conditions (25%), infection (14%), and cerebrovascular disease (9%). "The causes of death highlight the need for aggressive management of cardiovascular risk, prevention of thromboembolism, and good infection control, and emphasize the need to achieve disease remission, normalizing cortisol levels," said lead study author Padiporn Limumpornpetch, MD, of the University of Leeds in England, in a statement.

  4. Are adrenal incidentalomas, which are found by chance on imaging, really harmless? In this paper, the authors looked at 32 studies, including 4121 patients with benign non-functioning adrenal tumours (NFATs) or adenomas that cause mild autonomous cortisol excess (MACE). Only 2.5% of the tumours grew to a clinically significant extent over a mean follow-up period of 50 months, and no one developed adrenal cancer. Of those patients with NFAT or MACE, 99.9% didn’t develop clinically significant hormone (cortisol) excess. This was a group (especially those with MACE) with a high prevalence of hypertension, diabetes, and obesity. This could be because adrenal adenomas promote cardiometabolic problems, or vice versa, or maybe this group with multimorbidities is more likely be investigated. Adrenal incidentalomas are already found in around 1 in 20 abdominal CT scans, and this rate is likely to increase as imaging improves. So it’s good news that this study supports existing recommendations, which say that follow-up imaging in the 90% of incidentalomas that are smaller than 4 cm diameter is unnecessary.

  5. A 42-year-old woman who presented to hospital with acute vision loss in her right eye was diagnosed with a benign tumour in her adrenal gland. Writing in BMJ Case Reports, clinicians described how the patient presented with a visual acuity of 6/36 in her right eye and 6/6 in her left eye. Investigations revealed an exudative retinal detachment in her right eye as well as a pigment epithelial detachment. The patient had multifocal central serous retinopathy in both eyes. The woman, who had hypertension and diabetes, was diagnosed with Cushing syndrome and a right adrenal adenoma was also discovered. During a treatment period that spanned several years, the patient received an adrenalectomy followed by a maintenance dose of steroids. The patient subsequently developed central serous retinopathy again which the clinicians believe might be related to steroid use. The authors advised “careful deliberation” in prescribing a maintenance dose of steroids following removal of the adrenal glands because of the potential link to retinopathy.
