The Role of Endocrinology in Managing Polycystic Ovary Syndrome and Diabetes

Posted on September 28, 2023 by MaryO

Introduction to Endocrinology

Endocrinology is a medical specialty that focuses on the diagnosis and treatment of diseases related to hormones. Endocrinologists are experts in managing and treating diseases related to the endocrine system, which includes the thyroid, pituitary, adrenal glands, and pancreas. Endocrinologists are trained to diagnose and treat conditions such as diabetes, thyroid disorders, pituitary disorders, and other conditions related to hormones. Endocrinologists also specialize in reproductive health and fertility issues, including PCOS.

Endocrinology is a complex field that requires a deep understanding of the endocrine system and its role in regulating the body’s hormones. Endocrinologists must be able to interpret laboratory tests and understand the underlying causes of endocrine disorders. They must also be able to develop individualized treatment plans to address the specific needs of each patient.

Diagnosing PCOS and Diabetes

Endocrinologists are experts in diagnosing and managing PCOS and diabetes. PCOS is a hormonal disorder that affects the ovaries, and it is characterized by irregular menstrual cycles, excess facial and body hair, and infertility. To diagnose PCOS, an endocrinologist will perform a physical exam and order laboratory tests to measure hormone levels. The endocrinologist will also ask the patient about her symptoms and family history to determine if PCOS is the cause.

Diabetes is a chronic condition that affects the body’s ability to process sugar. To diagnose diabetes, an endocrinologist will perform a physical exam and order laboratory tests to measure blood sugar levels. The endocrinologist may also order imaging tests to check for signs of diabetes-related complications.

Treating PCOS and Diabetes

Once the endocrinologist has diagnosed PCOS or diabetes, they will develop an individualized treatment plan to address the patient’s specific needs. For PCOS, the endocrinologist may recommend lifestyle changes such as weight loss, exercise, and dietary changes to help manage symptoms. The endocrinologist may also prescribe medications to regulate hormone levels and improve fertility.

For diabetes, the endocrinologist may recommend lifestyle changes such as weight loss, exercise, and dietary changes to help manage blood sugar levels. The endocrinologist may also prescribe medications to help regulate blood sugar levels. In addition, the endocrinologist may recommend regular check-ups to monitor the patient’s progress and to adjust the treatment plan if needed.

Conclusion

Endocrinology plays an important role in managing PCOS and diabetes. Endocrinologists are experts in diagnosing and treating these conditions, and they are trained to develop individualized treatment plans that address the specific needs of each patient. By working with an endocrinologist, patients can get the help they need to manage their PCOS or diabetes and achieve their health goals.

Post-Operative Cushing Syndrome Care

Posted on January 22, 2022 by MaryO

Justine Herndon, PA-C, and Irina Bancos, MD, on Post-Operative Cushing Syndrome Care

– Curative procedures led to widespread resolution or improvement of hyperglycemia

by Scott Harris , Contributing Writer, MedPage Today January 18, 2022

In a recent study, two-thirds of people with Cushing syndrome (CS) saw resolved or improved hyperglycemia after a curative procedure, with close post-operative monitoring an important component of the process.

Among 174 patients with CS included in the longitudinal cohort study (pituitary in 106, ectopic in 25, adrenal in 43), median baseline HbA1c was 6.9%. Of these, 41 patients were not on any therapy for hyperglycemia, 93 (52%) took oral medications, and 64 (37%) were on insulin.

At the end of the period following CS remission (median 10.5 months), 37 (21%) patients had resolution of hyperglycemia, 82 (47%) demonstrated improvement, and 55 (32%) had no change or worsened hyperglycemia. Also at the end of follow-up, HbA1c had fallen 0.84% (P<0.0001), with daily insulin dose decreasing by a mean of 30 units (P<0.0001).

Justine Herndon, PA-C, and Irina Bancos, MD, both endocrinology researchers with Mayo Clinic in Minnesota, served as co-authors of the report, which was published in the Journal of the Endocrine Society. Here they discuss the study and its findings with MedPage Today. The exchange has been edited for length and clarity.

What was the study’s main objective?

Herndon: As both a hospital diabetes provider and clinic pituitary/gonadal/adrenal provider, I often hear questions from colleagues about how to manage a patient’s diabetes post-operatively after cure from CS. While clinical experience has been helpful in guiding these discussions, the literature offered a paucity of data on diabetes/hyperglycemia specifically after surgery. There was also a lack of data on specific subgroups of CS, whether by sub-type or severity.

Therefore, we felt it was important to see what our past patient experiences showed in terms of changes in laboratory data, medications, and which patients were more likely to see improvement in their diabetes/hyperglycemia. The overall goal was to help clinicians provide appropriate patient education and care following a curative procedure.

In addition to its primary findings, the study also identified several factors associated with resolution or improvement of hyperglycemia. What were these factors?

Bancos: Both clinical and biochemical severity of CS, as well as Cushing subtype, were associated with improvement. We calculated severity based on symptoms and presence of comorbidities, and we calculated biochemical severity based on hormonal measurements. As clinical and biochemical scores were strongly correlated, we chose only one (biochemical) for multivariable analysis.

In the multivariable analysis of biochemical severity of Cushing, subtype of Cushing, and subtype of hyperglycemia, we found that patients with a severe biochemical severity score were 2.4 fold more likely to see improved hyperglycemia than people with a moderate or mild severity score (OR 2.4 (95% CI 1.1-4.9). We also found that patients with the nonadrenal CS subtype were 2.9 fold more likely to see improved hyperglycemia when compared to people with adrenal CS (OR of 2.9 (95% CI 1.3-6.4).

The type of hyperglycemia (diabetes versus prediabetes) was not found to be significant.

Did anything surprise you about the study results?

Herndon: I was surprised to see improvement in hyperglycemia in patients who were still on steroids, as you would expect the steroids to still have an impact. This shows how much a CS curative procedure truly leads to changes in the comorbidities that were a result of the underlying disease.

Also, I was surprised that the type of hyperglycemia was not a predictor of improvement after cure, although it was quite close. We also had a few patients whose hyperglycemia worsened, and we could not find a specific factor that predicted which patients did not improve.

What are the study’s implications for clinicians who treat people with CS?

Bancos: We think our study shows the clear need for closer follow-up — more frequently than the typical three-to-six months for diabetes. This can be accomplished through review of more than just HbA1c, such as reviewing blood glucose logbooks, asking about hypoglycemia symptoms, and so forth.

Patients with severe CS who are being treated with insulin or hypoglycemic medications are especially likely to decrease their medications to avoid hypoglycemia during postoperative period.

Hypopituitarism and COVID-19 – exploring a possible bidirectional relationship?

Posted on September 7, 2021 by MaryO

As of September 1, 2021, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the virus responsible for the coronavirus disease 2019 (COVID-19), has infected over 219 million and caused the deaths of over 4.5 million worldwide. Although COVID-19 has been traditionally associated with its ability to cause varied symptoms resembling acute respiratory distress syndrome (ARDS), emerging scientific evidence has demonstrated that SARS-CoV-2 causes much more damage beyond its effects on the upper respiratory tract.

To this end, in a recent study published in Reviews in Endocrine and Metabolic Disorders, the researchers discuss the extra-pulmonary manifestations of COVID-19.

Risk factors for severe COVID-19

It is now a well-known fact that the likelihood of people falling severely ill or dying from COVID-19 is increases if these individuals are obese, or have certain comorbidities like diabetes mellitus (DM), vitamin D deficiency, and vertebral fractures (VFs).

Any abnormality in the pituitary gland may lead to metabolic disorders, impaired immunity, and a host of other conditions that also make the body susceptible to infections. Since such conditions are common in patients with COVID-19 as well, it has been hypothesized that there might be a relationship between COVID-19 and pituitary gland disorders.

On the other hand, researchers have also observed that COVID-19 causes increased severity of pituitary-related disorders, and even pituitary apoplexy, which is a condition defined as internal bleeding or impaired blood supply in the pituitary gland. A group of Italian researchers has reviewed this bidirectional relationship between the pituitary gland abnormalities and COVID-19 in their study recently published in Reviews in Endocrine and Metabolic Disorders.

The link between pituitary gland abnormalities and COVID19

The pituitary gland releases hormones that regulate and control some of the most important functions of the body like growth, metabolism, energy levels, bone health, mood swings, vision, reproduction, and immunity, to name a few. The inability of the pituitary gland to release one or more of these hormones is known as ‘hypopituitarism.’  Factors responsible for hypopituitarism include traumatic brain injury, pituitary adenomas (tumors), genetic mutations, as well as infiltrative and infectious diseases.

Hypopituitarism can lead to severe cases of DM, growth hormone deficiency (GHD), abnormal lipid profile, obesity, arterial hypertension, and immune dysfunctions. Interestingly, similar consequences of COVID-19 have also been reported.

SARS-CoV-2 infects the human body by binding to a special class of receptors known as the angiotensin-converting enzyme 2 (ACE2) receptors. These receptors are located in the endothelial linings of most organs like the brain, heart, lungs, kidneys, intestine, liver, and pancreas, among others. The main function of the ACE2 receptors is binding to specific target molecules to maintain the renin-angiotensin system that is crucial for regulating dilation of blood vessels, as well as maintain blood glucose levels, the immune system, and homeostasis.

Therefore, SARS-CoV-2 binding to these ACE2 receptors facilitates the entry of this virus into all the organs that have these receptors, thus leading to the ability of SARS-CoV-2 to cause widespread damage in the body. Upon entry into the pancreas, for example, SARS-CoV-2 can inhibit ß-cells function, which worsens hyperglycemia and increases the risk for acute diabetic complications.

Similarly, the presence of ACE2 receptors in brain tissues may cause invasion into the pituitary gland and lead to pituitary apoplexy. The entry of SARS-CoV-2 into the brain can also cause neurological damage in infected patients, which may account for some of the common neurological complaints of COVID-19 including headaches, confusion, dysgeusia, anosmia, nausea, and vomiting.

Study findings

Hypopituitarism leading to metabolic syndrome has been scientifically linked to higher mortality in COVID-19 patients. In fact, the presence of a single metabolic syndrome component has been observed to double the risk of death by COVID-19. This risk was even higher among patients with DM and hypertension.

There was also an increased incidence of VFs in COVID-19 patients with hypopituitarism. Hence, patients with DM, obesity, hypertension, and chronic inflammatory disease, are all at an increased risk of poor outcomes and death in COVID-19.

Arterial hypertension is a common finding in adults with GHD, which is another consequence of hypopituitarism. Hypopituitarism also causes adrenal insufficiency, a condition that is primarily managed with glucocorticoids and hormonal replacement therapies.

Notably, patients with COVID-19 are often treated for prolonged periods with high-dose exogenous glucocorticoids, which is a class of steroids that suppress some activities of the immune system. This treatment approach may result in suppression of the hypothalamic-pituitary–adrenal axis that can lead to adrenal insufficiency.

Hypogonadism is another aspect of pituitary insufficiency that predisposes patients, especially males, to COVID-19. Evidence shows that males with hypogonadism were more frequently affected by metabolic syndrome.

Pituitary apoplexy, albeit rare, has also been linked to COVID-19, especially in patients with pituitary adenomas and those who are being treated with anticoagulant therapy. This may be because the pituitary gland becomes overstimulated during an infectious disease, which may increase pituitary blood demand and lead to sudden infarction precipitating acute apoplexy.

This phenomenon has also been shown in patients suffering from infectious diseases that cause hemorrhagic fevers. Taken together, pituitary apoplexy complicates treatment and management procedures in COVID-19 patients.

Despite the use of steroids in COVID-19 patients, there have been no contraindications for vaccination in such patients. However, those on extensive hormonal therapies need constant monitoring for best results.

Implications

The pituitary gland acts like a double-edged sword for COVID-19. On one end, hypopituitarism predisposes patients to metabolic disorders like DM, obesity, and VFs, all of which are known risk factors for COVID-19.

On the other hand, COVID-19 may cause direct or indirect damage to the pituitary glands by entering the brain and inducing unfavorable vascular events – though evidence on this remains lesser in comparison to that of hypopituitarism. Ultimately, the researchers of the current study conclude that managing patients with hormonal insufficiencies optimally with steroids is likely to improve outcomes in severe COVID-19.

What Causes Blood Sugar to Rise in Non-Diabetics?

Posted on May 26, 2021 by MaryO

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.

Rapid Control Of Ectopic Cushing’s Syndrome During The Covid-19 Pandemic in a Patient With Chronic Hypokalaemia

Posted on May 25, 2021 by MaryO

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.
