Bridget Houser felt despairing. In the months before her 2018 wedding, Houser, who had never struggled with her weight, noticed that it inexplicably began to creep up. In response she doubled the length of her runs to eight miles, took back-to-back high intensity workout classes and often consumed only water, coffee and fruit during the day before a spartan, mostly vegetable, dinner. Yet no matter what Houser did, her weight stubbornly increased and her oval face grew round, a transformation that was glaringly obvious in comparison with her identical twin sister. Houser wondered whether the five pounds she gained despite her herculean effort was a corollary of other problems. For the previous two years she had battled a string of maladies: first daily headaches, then crippling anxiety, followed by insomnia, hair loss and acne, something she’d never endured as a teenager. “Stress was the universal explanation,” recalled Houser, a controller for a small business in Chicago. When doctors suggested that her upcoming marriage might be a cause of her problems, Houser considered, then rejected, the theory. It just didn’t jibe with her feelings. In early 2019, about six months after her wedding, Houser insisted that her doctors perform several tests. They ultimately revealed that her symptoms weren’t the result of stress or marital misgivings but of a serious illness that had been smoldering for years. After successful treatment followed by a long recovery Houser, now 34, feels far better than she did during those miserable years in her late 20s. “I wish I’d been nicer to myself and not blamed myself for what was going on,” she said. Getting through the wedding In 2016 Houser began experiencing daily pain in the back of her head, a common spot for tension headaches. When the headaches failed to improve with dietary changes or nonprescription pain relievers, she consulted her primary care doctor, followed by a neurologist who told her she had migraines. Houser, then 27, noticed that the headaches were worse when she wore contact lenses. “It was affecting my daily life and I talked myself into thinking the problem was my contacts,” she said. She decided Lasik surgery might help and in October 2017 underwent the procedure, which uses a laser to reshape the cornea, reducing or eliminating dependence on contacts or glasses. Her vision improved and the pain disappeared — briefly. A week after eye surgery, her headaches returned. “I wasn’t overly concerned,” Houser said. “I know a lot of people have headaches.” A few months later for no apparent reason Houser developed “really bad anxiety. It wasn’t just like I was anxious,” she recalled. “I couldn’t function. I’m Type A so I knew what anxiety is, but not to this degree.” One weekday morning in early 2018 she felt so overwhelmed that she took a sick day, then called her twin, Molly, and their mother and told them she needed help immediately. They managed to schedule a same-day appointment with a psychiatrist whom Houser began seeing regularly, along with a therapist. The psychiatrist zeroed in on her impending wedding and told Houser that the event can cause “huge anxiety.” She began taking an antidepressant along with Ativan, an anti-anxiety drug she used when things got really bad. She also ramped up her yoga practice, hoping it might calm her. Houser vividly remembers riding the escalator to her office one morning “and in my head I kept saying, ‘I’m in trouble, I’m in trouble,’” although she didn’t know what was wrong. Her changing appearance had become a source of great unhappiness. Although her weight remained in the normal range, Houser couldn’t figure out why she was gaining weight after drastically slashing her food intake and dramatically ramping up exercise. Her normally thick hair had thinned so noticeably that her hairdresser gently advised her to consult a doctor. Houser’s psychiatrist thought her hair loss might be caused by her antidepressant and switched medications. That didn’t seem to help. Houser was particularly bothered by her newly chubby face. “It was like a joke in my family,” she said, adding that she was teased about being overly sensitive. Even her wedding day was colored by unhappiness about her appearance and the intense amorphous anxiety that seemed omnipresent. “Rather than think about how excited I was,” Houser recalled, “it was ‘How can I get through this day?’” Normal thyroid After her wedding Houser felt worse. She developed severe insomnia, night sweats and acne. In February 2019 a nurse practitioner in her primary care practice ordered tests of her thyroid, which were normal. When Houser pressed for additional testing, she was referred to an endocrinologist. He told her she was stressed. Dissatisfied, she saw a second endocrinologist who agreed with the first. “She said ‘I don’t think there’s anything wrong with you’” metabolically, Houser recalled. The second endocrinologist’s nurse even revisited the marriage question in the presence of Houser’s husband, Doug, who had accompanied her to the appointment. “She said ‘I knew on my honeymoon I shouldn’t have gotten married,’” Houser remembered her saying. “‘Are you in a happy marriage?’ I couldn’t believe it.” Months earlier, the nurse practitioner who ordered the thyroid tests briefly mentioned measuring levels of cortisol, a hormone involved in the body’s response to stress and other functions. Elevated levels of cortisol can indicate Cushing’s syndrome, an uncommon hormonal disorder that occurs when the body produces too much of the hormone over a prolonged period. “She had thrown cortisol testing out there and I think it was always in the back of my mind,” Houser said. She asked the second endocrinologist to order cortisol tests. The doctor agreed, but not before telling Houser that she didn’t think she had Cushing’s because she lacked the classic symptoms: major weight gain, purple stretch marks and a fatty hump between the shoulders. Houser did have the “moon face” characteristic of Cushing’s that is also seen in people who take high doses of steroids for long periods to treat various illnesses — but Houser wasn’t taking steroids. Insomnia, headaches, acne and anxiety can be symptoms of Cushing’s. There are several forms of Cushing’s syndrome, which typically results from a tumor — usually benign but sometimes cancerous — in the pituitary or adrenal gland that pumps out excess cortisol. Sometimes tumors develop elsewhere in the body such as the lungs or pancreas. Cushing’s affects roughly five times as many women as men and typically occurs between the ages of 30 and 50. If left untreated, it can be fatal. A trio of tests measuring cortisol levels in Houser’s blood, urine and saliva were significantly elevated; the amount in her urine was eight times higher than normal. The formerly skeptical Chicago endocrinologist told Houser she had Cushing’s and referred her to James Findling, a Milwaukee endocrinologist who is internationally recognized for his treatment of the disease. “I was just so happy to have a diagnosis,” Houser recalled. Revealing photos Findling asked Houser to bring photographs taken several years earlier to her October 2018 appointment. It is a request he makes of patients as a way of spotting telltale physical manifestations. In Houser’s case, the facial change was particularly striking because she is an identical twin. Findling noted that delayed diagnosis is typical, because physical changes and other symptoms tend to occur gradually and insidiously. Houser, he added, “didn’t look like the typical Cushing’s patient. She wasn’t obese and she didn’t have diabetes or hypertension. It was more subtle than many cases.” The next step was determining the location of the tiny tumor. Tests found nothing in Houser’s pituitary or adrenal glands, and CT scans of her pelvis, chest and abdomen were clean. Findling ordered a dotatate PET scan, a highly sensitive CT scan that can find tumors that elude conventional imaging. The scan revealed a nodule in Houser’s left lung. Houser sought a second opinion from a thoracic surgeon in Chicago. While Findling and a thoracic surgeon at Milwaukee’s Froedtert Hospital strongly recommended that she undergo surgery to remove the tumor, the Chicago doctor disagreed. He said he didn’t think the lung nodule was causing Cushing’s and recommended that Houser continue therapy and anti-anxiety medication. “Do you know what it’s like to wake up from surgery and to not be better?” she remembers him asking her. After deliberating with her husband and conferring with her Milwaukee doctors, Houser opted for surgery performed Oct. 30, which removed part of her left lung. A pathologist determined that the nodule was a rare, slow-growing neuroendocrine lung cancer known as a bronchial carcinoid, which can cause Cushing’s. The Stage 2 cancer had spread to a nearby lymph node. “Fortunately I think we got it early,” Findling said. “She’s had a sustained remission and a cure of her Cushing’s.” “The cancer didn’t rock my world,” said Houser, who had previously had a melanoma skin cancer removed. (Doctors have told her they don’t think the cancers are related.) “It was about not having Cushing’s anymore, which was more important.” So why didn’t Houser’s doctors, among them endocrinologists, suspect Cushing’s? Findling, who estimates he has treated as many as 2,000 people with the disease in his 40-year career, said that while doctors are taught that Cushing’s is rare, it’s not. He cites a 2016 study, which that found that 26 of 353 endocrinology patients were found to have the disease. Textbook descriptions, which include the presence of purple stretch marks and a hump, are “almost a caricature,” Findling observed. “It’s pretty well recognized that Cushing’s is more subtle than that … and can cause neuropsychiatric and neurocognitive problems.” Houser’s normal weight and the fact that she didn’t have high blood pressure or diabetes may have misled doctors. “I think we’ve moved the needle a little bit, especially among endocrinologists,” he continued, adding that “the threshold for screening has got to change. Once you tell a primary care doctor that it’s a rare disorder, it goes in one ear and out the other. They think they’ll never see it.” “When you make this diagnosis it can have fabulous outcomes,” he added, citing Houser’s case. “That’s why I’m still doing this at my age.” Houser considers Findling to be her “literal lifesaver.” She spent the next year seeing him as she was slowly weaned off medications to normalize her hormone levels and recover her strength. She is monitored for Cushing’s annually, remains cancer-free and, other than residual fatigue, feels well. In October 2021 she gave birth to a daughter. Her son was born eight weeks ago. Houser regards the help provided by her family, particularly her husband whom she called “my biggest supporter,” as essential. That seems especially ironic because stress about their marriage had been blamed for symptoms that were actually caused by a cancer. “He was a huge help in calling doctors and making the necessary appointments when I didn’t have the energy to fight anymore.” His unwavering love, she said, was “a testament to our strong marriage.” From https://www.washingtonpost.com/wellness/2023/10/07/weight-anxiety-wedding-medical-mysteries/

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. Endocrinology is a complex field that requires a deep understanding of the endocrine system and its role in regulating the body’s hormones. An endocrinologist can help patients with PCOS and diabetes manage their conditions and achieve their health goals. By working with an endocrinologist, patients can get the help they need to manage their PCOS or diabetes and achieve their health goals.

A TSH test is done to find out if your thyroid gland is working the way it should. It can tell you if it’s overactive (hyperthyroidism) or underactive (hypothyroidism). The test can also detect a thyroid disorder before you have any symptoms. If untreated, a thyroid disorder can cause health problems. TSH stands for “thyroid stimulating hormone” and the test measures how much of this hormone is in your blood. TSH is produced by the pituitary gland in your brain. This gland tells your thyroid to make and release the thyroid hormones into your blood. The Test The TSH test involves simply drawing some blood from your body. The blood will then be analyzed in a lab. This test can be performed at any time during the day. No preparation is needed (such as overnight fasting). You shouldn’t feel any pain beyond a small prick from the needle in your arm. You may have some slight bruising. In general, there is no need to stop taking your medicine(s) before having your TSH level checked. However, it is important to let the doctor know what medications you are taking as some drugs can affect thyroid function. For example, thyroid function must be monitored if you are taking lithium. While taking lithium, there is a high chance that your thyroid might stop functioning correctly. It's recommended that you have a TSH level test before starting this medicine. If your levels are normal, then you can have your levels checked every 6 to 12 months, as recommended by your doctor. If your thyroid function becomes abnormal, you should be treated. High Levels of TSH TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid. In general, T3 and T4 levels increase in pregnancy and TSH levels decrease. Low Levels of TSH It's also possible that the test reading comes back showing lower than normal levels of TSH and an overactive thyroid. This could be caused by: Graves’ disease (your body’s immune system attacks the thyroid) Too much iodine in your body Too much thyroid hormone medication Too much of a natural supplement that contains the thyroid hormone If you're on medications like steroids, dopamine, or opioid painkillers (like morphine), you could get a lower-than-normal reading. Taking biotin (B vitamin supplements) also can falsely give lower TSH levels. The TSH test usually isn’t the only one used to diagnose thyroid disorders. Other tests, like the free T3, the free T4, the reverse T3, and the anti-TPO antibody, are often used too when determining whether you need thyroid treatment or not. Treatment Treatment for an underactive thyroid usually involves taking a synthetic thyroid hormone by pill daily. This medication will get your hormone levels back to normal, and you may begin to feel less tired and lose weight. To make sure you're getting the right dosage of medication, your doctor will check your TSH levels after 2 or 3 months. Once they are sure you are on the correct dosage, they will continue to check your TSH level each year to see whether it is normal. If your thyroid is overactive, there are several options: Radioactive iodine to slow down your thyroid Anti-thyroid medications to prevent it from overproducing hormones Beta blockers to reduce a rapid heart rate caused by high thyroid levels Surgery to remove the thyroid (this is less common) Your doctor may also regularly check your TSH levels if you have an overactive thyroid.

The pituitary gland works hard to keep you healthy, doing everything from ensuring proper bone and muscle growth to helping nursing mothers produce milk for their babies. Its functionality is even more remarkable when you consider the gland is the size of a pea. “The pituitary is commonly referred to as the ‘master’ gland because it does so many important jobs in the body,” says Karen Frankwich, MD, a board-certified endocrinologist at Mission Hospital. “Not only does the pituitary make its own hormones, but it also triggers hormone production in other glands. The pituitary is aided in its job by the hypothalamus. This part of the brain is situated above the pituitary, and sends messages to the gland on when to release or stimulate production of necessary hormones.” These hormones include: Growth hormone, for healthy bone and muscle mass Thyroid-stimulating hormone, which signals the thyroid to produce its hormones that govern metabolism and the body’s nervous system, among others Follicle-stimulating and luteinizing hormones for healthy reproductive systems (including ovarian egg development in women and sperm formation in men, as well as estrogen and testosterone production) Prolactin, for breast milk production in nursing mothers Adrenocorticotropin (ACTH), which prompts the adrenal glands to produce the stress hormone cortisol. The proper amount of cortisol helps the body adapt to stressful situations by affecting the immune and nervous systems, blood sugar levels, blood pressure and metabolism. Antidiuretic (ADH), which helps the kidneys control urine levels Oxytocin, which can stimulate labor in pregnant women The work of the pituitary gland can be affected by non-cancerous tumors called adenomas. “These tumors can affect hormone production, so you have too little or too much of a certain hormone,” Dr. Frankwich says. “Larger tumors that are more than 1 centimeter, called macroadenomas, can also put pressure on the area surrounding the gland, which can lead to vision problems and headaches. Because symptoms can vary depending on the hormone that is affected by a tumor, or sometimes there are no symptoms, adenomas can be difficult to pinpoint. General symptoms can include nausea, weight loss or gain, sluggishness or weakness, and changes in menstruation for women and sex drive for men.” If there’s a suspected tumor, a doctor will usually run tests on a patient’s blood and urine, and possibly order a brain-imaging scan. An endocrinologist can help guide a patient on the best course of treatment, which could consist of surgery, medication, radiation therapy or careful monitoring of the tumor if it hasn’t caused major disruption. “The pituitary gland is integral to a healthy, well-functioning body in so many ways,” Dr. Frankwich says. “It may not be a major organ you think about much, but it’s important to know how it works, and how it touches on so many aspects of your health.” Adapted from http://www.stjhs.org/HealthCalling/2016/December/The-Pituitary-Gland-Small-but-Mighty.aspx

First published: 06 November 2021 https://doi.org/10.1111/cen.14617 Abstract Objective Ectopic Cushing′s syndrome (ECS) induced by medullary thyroid cancer (MTC) is rare, and data on clinical characteristics, treatment and outcome are limited. Design Retrospective cohort study in three German and one Swiss referral centres. Patients Eleven patients with MTC and occurrence of ECS and 22 matched MTC patients without ECS were included. Measurements The primary endpoint of this study was the overall survival (OS) in MTC patients with ECS versus 1:2 matched MTC patients without ECS. Results The median age at diagnosis of ECS was 59 years (range: 35–81) and the median time between initial diagnosis of MTC and diagnosis of ECS was 29 months (range: 0–193). Median serum morning cortisol was 49 µg/dl (range: 17–141, normal range: 6.2–18). Eight (73%) patients received treatment for ECS. Treatment of ECS consisted of bilateral adrenalectomy (BADX) in four (36%) patients and adrenostatic treatment in eight (73%) patients. One patient received treatment with multityrosine kinase inhibitor (MKI) to control hypercortisolism. All patients experienced complete resolution of symptoms of Cushing's syndrome and biochemical control of hypercortisolism. Patients with ECS showed a shorter median OS of 87 months (95% confidence interval [95% CI]: 64–111) than matched controls (190 months, 95% CI: 95–285). Of the nine deaths, four were related to progressive disease (PD). Four patients showed PD as well as complications and comorbidities of hypercortisolism before death. Conclusion This study shows that ECS occurs in advanced stage MTC and is associated with a poor prognosis. Adrenostatic treatment and BADX were effective systemic treatment options in patients with MTC and ECS to control their hypercortisolism. MKI treatment achieved complete remission of hypercortisolism and sustained tumour control in one treated case. 1 INTRODUCTION Medullary thyroid cancer (MTC) arises from calcitonin-producing parafollicular C-cells of the thyroid gland and accounts for 2%–5% of all thyroid malignancies.1 In about 25% of cases, MTC occurs in a hereditary manner as a part of multiple endocrine neoplasia type 2 (MEN2) caused by oncogenic germline REarranged during Transfection (RET)-mutations. Up to 65% of patients with the sporadic disease have somatic RET-mutations, among which RETM918T is the most common and associated with adverse outcome.2-5 At diagnosis, cervical lymph node metastases are present in about half of patients and distant metastases in around 10% of MTC patients.6 While the localized disease has a 10-year disease-specific survival (DSS) of 96%, 10-year DSS is only 44% in cases with distant metastases.7-9 Besides calcitonin and carcinoembryonic antigen (CEA), C-cells may also ectopically secrete corticotropin-releasing hormone (CRH) or adrenocorticotropic hormone (ACTH). Cushing's syndrome (CS) due to ectopic CRH or ACTH secretion induced by MTC is rare and data on clinical characteristics, treatment and outcome are limited and mostly from case studies. In a retrospective study of 1640 adult patients with MTC, ectopic Cushing's syndrome (ECS) due to ACTH secretion was reported in only 0.6% of patients, whereas previous studies reported a higher prevalence, possibly due to selection bias.10-12 ECS mostly occurs in metastatic cases and significantly impairs prognosis: around 50% of the mortality in patients with ECS has been attributed to complications of hypercortisolism.12 Diagnosis of ECS is difficult and includes a combination of clinical assessment, dynamic biochemical tests (e.g., 24 h urinary-free cortisol, midnight salivary cortisol, 1 and 8 mg dexamethasone suppression test), inferior petrosal sinus sampling (IPSS) and multimodal imaging.13 This retrospective study aims at describing clinical characteristics, treatment and prognosis of 11 patients with MTC and ECS at 3 German and 1 Swiss tertiary care centres and to illustrate effective treatment in this ultrarare condition. 2 PATIENTS AND METHODS 2.1 Setting This registry study was conducted as part of the German Study Group for Rare Malignant Tumours of the Thyroid and Parathyroid Glands. Data were obtained from records of patients diagnosed with MTC between 1990 and 2020 and concomitant ECS diagnosed between 1995 and 2020 in three German and one Swiss tertiary care centres. All patients provided written informed consent and the study was approved by the ethics committee of the University of Würzburg (96/13) and subsequently by the ethics committees of all participating centres. 2.2 Data acquisition Eligible patients were 11 adults with histopathological evidence of MTC and the diagnosis of ECS at initial diagnosis (synchronous CS) or during the course of disease (metachronous CS). This group was matched with 22 patients with histologically confirmed MTC without evidence of ECS by sex, age at MTC diagnosis (±5 years), tumour stage and calcitonin doubling time (CDT). The diagnosis of ECS was established by standard endocrine testing according to international guideline recommendations,14 local good clinical practice procedures and laboratory assays in participating centres. The primary endpoint of this study was the assessment of overall survival (OS) in MTC patients with ECS from the date of MTC-diagnosis and the date of ECS-diagnosis versus matched MTC patients without ECS (1:2 ratio). The secondary endpoints were assessment of progression-free survival (PFS) and efficacy of multityrosine kinase inhibitors (MKIs) treatment (based on routine clinical imaging in analogy to RECIST 1.0 and 1.1). Treatment and follow-up of patients were performed according to the local practice of participating centres. Efficacy was assessed locally by imaging (positron emission tomography/computed tomography [PET/CT], CT, magnetic resonance imaging [MRI] of the liver and bone scintigraphy) and measurement of serum calcitonin and CEA levels every 3–6 months. Clinical data were recorded by trained personnel at all sites. Tumour stage was defined according to the American Joint Committee on Cancer TNM classification, seventh edition,15 based on clinical and histopathological assessments. 2.3 Statistical analysis PFS and OS probabilities were estimated using the Kaplan–Meier method. The log-rank test was not used to test the difference between the study group and the control group due to the paired sample design. For the comparison of nonnormally distributed data, we used the Mann–Whitney U test. p Values less than .05 were considered statistically significant. Statistical analyses were performed with SPSS Version 26 (IBM). 3 RESULTS 3.1 Clinical characteristics of patients with ECS Eleven patients (five male and six female) with histopathological evidence of MTC with ECS in three German and one Swiss tertiary care centres were included. Twenty-two controls with histologically confirmed MTC without the diagnosis of ECS matched by sex, age at MTC diagnosis (±5 years), tumour stage and CDT were enroled. Baseline clinical characteristics of the study population and the control group are shown in Table 1. In patients with ECS, median follow-up from initial MTC diagnosis was 6.3 years (range: 0–17) and median follow-up from diagnosis of ECS 7 months (range: 0–110). Median age at initial diagnosis of sporadic MTC was 45 (range: 31–67, n = 7) and 52 years (range: 35–55, n = 3) for patients with germline RET mutant MTC.

Dr. Friedman is getting a lot of emails on booster shots versus third shots. Third shots are for immuno-compromised patients that the FDA is recommending for a small group of patients The FDA also has the intention to soon make booster doses widely available to all healthy individuals. I am writing to clarify the difference between booster shots and third doses. Third Doses for Immuno-Compromised Patients The purpose of a third dose of mRNA vaccine is to give immuno-compromised patients the same level of protection that two doses provide someone who has a normal immune system. It is recommended that the following people get a third dose Been receiving cancer treatment for tumors or cancers of the blood Received an organ transplant and are taking medicine to suppress the immune system Received a stem cell transplant within the last two years or are taking medicine to suppress the immune system Been diagnosed with moderate or severe immunodeficiency conditions (such as DiGeorge syndrome, Wiskott-Aldrich syndrome) An advanced or untreated HIV infection Been under active treatment with high-dose corticosteroids (> 20 mg of prednisone or 100 mg of hydrocortisone) or other drugs that may suppress immune response Dr. Friedman thinks it is unlikely that any of his patients have these conditions. Patients with Cushing’s syndrome, Addison’s, diabetes or thyroid disorders do not qualify. In contrast, a Booster Dose is for Patients With Healthy Immune Systems A booster dose—which is different from a third dose for immuno-compromised patients—is for healthy patients and is meant to enhance immunity and may protect against new variants of the virus. The Biden administration has announced that it intends to make booster doses available for people with healthy immune systems in September 2021, after they are authorized or approved by the FDA. This has not happened yet, but when it happens, Dr. Friedman would encourage his patients to get it. Dr. Friedman is expecting a booster shot against the Delta variant to be released in the fall of 2021 and would recommend that for his patients. Dr. Friedman wishes everyone to stay healthy.

Central hypothyroidism is prevalent in about 1 in 2 adults with Cushing’s syndrome, and thyroid function can be restored after curative surgery for most patients, according to study findings. “Our study findings have confirmed and greatly extended previous smaller studies that suggested a link between hypercortisolism and thyroid dysfunction but were inconclusive due to smaller sample size and short follow-up,” Skand Shekhar, MD, an endocrinologist and clinical investigator in the reproductive physiology and pathophysiology group at the National Institute of Environmental Health Sciences, NIH, told Healio. “Due to our large sample and longer follow-up, we firmly established a significant negative correlation between hypercortisolemia measures — serum and urinary cortisol, serum adrenocorticotropic hormone — and thyroid hormones triiodothyronine, free thyroxine and thyrotropin.” Shekhar and colleagues conducted a retrospective review of two groups of adults aged 18 to 60 years with Cushing’s syndrome. The first group was evaluated at the NIH Clinical Center from 2005 to 2018 (n = 68; mean age, 43.8 years; 62% white), and the second group was evaluated from 1985 to 1994 (n = 55; mean age, 37.2 years; 89% white). The first cohort was followed for 6 to 12 months to observe the pattern of thyroid hormone changes after surgical cure of adrenocorticotropic hormone-dependent Cushing’s syndrome. The second group underwent diurnal thyroid-stimulating hormone evaluation before treatment and during remission for some cases. Urinary free cortisol and morning thyroid hormone levels were collected for all participants. In the second group, researchers evaluated diurnal patterns of TSH concentrations with hourly measurements from 3 to 7 p.m. and midnight to 4 p.m. In the first group, adrenocorticotropic hormone and serum cortisol were measured. In the first cohort, seven participants were receiving levothyroxine for previously diagnosed primary or central hypothyroidism. Of the remaining 61 adults, 32 had untreated central hypothyroidism. Thirteen participants had free T4 at the lower limit of normal, and 19 had subnormal levels. There were 29 adults with subnormal levels of T3 and seven with subnormal TSH. Before surgery, 36 participants in the first group had central hypothyroidism. Six months after surgery, central hypothyroidism remained for 10 participants. After 12 months, the number of adults with central hypothyroidism dropped to six. Preoperative T3 and TSH levels were negatively associated with morning and midnight cortisol, adrenocorticotropic hormone and urinary free cortisol. In post hoc analysis, a baseline urinary free cortisol of more than 1,000 g per day was adversely associated with baseline and 6-month T3 and free T4 levels. In the second group, there were 51 participants not on thyroid-modifying drugs who had a thyroid function test 6 or 12 months after surgery. Before surgery, free T4 levels were subnormal in 17 participants, T3 levels were subnormal in 22, and TSH levels were in the lower half of the reference range or below in all but one participant. After surgery, two participants had below normal free T4, one had subnormal T3, and TSH levels were in the lower half of the reference range or below in 23 of 48 participants. Before surgery, there was no difference in mean TSH between daytime and nighttime. A mean 8 months after surgery, the second group had a normal nocturnal TSH surge from 1.3 mIU/L during the day to 2.17 mIU/L at night (P = .01). The nocturnal TSH increase persisted as long as 3 years in participants who had follow-up evaluations. “We found a very high prevalence of thyroid hormone deficiency that appears to start at the level of the hypothalamus-pituitary gland and extend to the tissue level,” Shekhar said. “Some of these patients may experience thyroid hormone deficiency symptoms, such as fatigue, depression, cold intolerance, weight gain, etc, as a result of systematic and tissue-level thyroid hormone deficiency. We also noted a strong correlation between hypothyroidism and hypogonadism, which implies that hypothyroid patients are also likely to suffer adverse reproductive effects. Thus, it is imperative to perform thorough thyroid hormone assessment in patients with Cushing’s syndrome, and thyroid hormone supplementation should be considered for these patients unless cure of Cushing’s syndrome is imminent.” Researchers said providers should routinely screen for hypothyroidism in adults with Cushing’s syndrome. Even after thyroid function is restored, regular follow-up should also be conducted. Further research is needed to investigate thyroid dysfunction in iatrogenic Cushing’s syndrome and the impact of these findings on euthyroid sick syndrome, Shekhar said.

Thyroid cancer survival rates are 84 percent for 10 years or more if diagnosed early. Early diagnosis is crucial therefore and spotting the unusual signs could be a matter of life and death. A sign your thyroid cancer has advanced includes Cushing syndrome. What is it? What is Cushing syndrome? Cushing syndrome occurs when your body is exposed to high levels of the hormone cortisol for a long time, said the Mayo Clinic. The health site continued: “Cushing syndrome, sometimes called hypercortisolism, may be caused by the use of oral corticosteroid medication. “The condition can also occur when your body makes too much cortisol on its own. “Too much cortisol can produce some of the hallmark signs of Cushing syndrome — a fatty hump between your shoulders, a rounded face, and pink or purple stretch marks on your skin.” In a study published in the US National Library of Medicine National Institutes of Health, thyroid carcinoma and Cushing’s syndrome was further investigated. The study noted: “Two cases of thyroid carcinoma and Cushing's syndrome are reported. “Both of our own cases were medullary carcinomas of the thyroid, and on reviewing the histology of five of the other cases all proved to be medullary carcinoma with identifiable amyloid in the stroma. “A consideration of the temporal relationships of the development of the carcinoma and of Cushing's syndrome suggested that in the two cases with papillary carcinoma these conditions could have been unrelated, but that in eight of the nine cases with medullary carcinoma there was evidence that thyroid carcinoma was present at the time of diagnosis of Cushing's syndrome. “Medullary carcinoma of the thyroid is also probably related to this group of tumours. It is suggested that the great majority of the tumours associated with Cushing's syndrome are derived from cells of foregut origin which are endocrine in nature.” In rare cases, adrenal tumours can cause Cushing syndrome a condition arising when a tumour secretes hormones the thyroid wouldn’t normally create. Cushing syndrome associated with medullary thyroid cancer is uncommon. The syndrome is more commonly caused by the pituitary gland overproducing adrenocorticotropic hormone (ACTH), or by taking oral corticosteroid medication. See a GP if you have symptoms of thyroid cancer, warns the NHS. The national health body added: “The symptoms may be caused by less serious conditions, such as an enlarged thyroid, so it's important to get them checked. “A GP will examine your neck and can organise a blood test to check how well your thyroid is working. “If they think you could have cancer or they're not sure what's causing your symptoms, you'll be referred to a hospital specialist for more tests.” Adapted from https://www.express.co.uk/life-style/health/1351753/thyroid-cancer-signs-symptoms-cushing-syndrome

Dr. Friedman wants to update his patients about natural desiccated thyroid (NDT) recalls based on new information from the FDA. Dr. Friedman prescribes various thyroid hormone preparations to his patients with hypothyroidism. This includes natural desiccated thyroid (NDT) of which two preparations are WP Thyroid and Nature-Throid, both made by RLC Labs. On August 25, 2020, RLC Labs announced a voluntary, consumer-level recall of all lots of Nature-Throid and WP Thyroid tablets because some lots contain less than the required 90% of the active ingredient as determined by the FDA. The RLC spokesperson said to Dr. Friedman that one lot of WP Thyroid and 5 lots of Nature-Throid contained between 87% and 90% of the labeled amount of levothyroxine (T4) or liothyronine (T3). Recently the FDA announced which lots are recalled that are listed below. According to the recall, if a patient receives a sub-potent tablet, hypothyroid symptoms may not be controlled. To date, there have been no reports of adverse events related to this recall. Patients who have had an adverse event should contact RLC Labs. The lot numbers are listed on the bottles of Nature-Throid and WP Thyroid. With this information about which lots are recalled, Dr. Friedman is only recommended those taking the effective lots to discontinue them. Currently no lots of Nature-Throid and WP Thyroid tablets are commercially available, so a replacement with the same product is not an option. It is unknown how long it will be before Nature-Throid and WP Thyroid become commercially available. In September 2020, the FDA also announced that two lots (one of 15 mg and one of 120 mg) (see table) of NP Thyroid made by Acella Pharamceuticals were also recalled due to reduced potency between 87% and 90% of the labeled amount of levothyroxine (T4) or liothyronine (T3). Other lots are currently available. The lot numbers are not listed on the Acella product bottles, but the expiration dates are. If patient has one of the products with the expiration date listed, they can ask their pharmacy for the lot number. Dr. Friedman has several comments about these recalls. Dr. Friedman sees them as unfortunate, but still believes NDT is a good option for patients with hypothyroidism. The “subpotent” Nature-Throid, WP Thyroid and NP Thyroid pills are only slightly less potent than stated in that only the effective lots are between 87% and 90% of the T4 and T3 levels. For most patients, they will not have symptoms from these subpotent pills and if they are taking a lot that is subpotent, the dose can be adjusted based on laboratory levels at your next appointment with Dr. Friedman. According to Dr. Friedman, patients taking Nature-Throid and WP Thyroid with the subpotent lots have three options: 1) they can continue taking Nature-Throid and WP Thyroid knowing they may have a subpotent lot and knowing that they may not be able to get a refill at least temporarily. 2) patients can be switched to Armour thyroid, NP thyroid or have a compounding pharmacy compound the equivalent dose using USP grade porcine powder. Please let Dr. Friedman’s office know if you would like to go on a different desiccated thyroid product (and which one) and what pharmacy you would like to use, 3) Dr. Friedman has a small supply of desiccated thyroid with no reclled lots that is available at his clinic for those in Los Angeles on the last Tuesday night of each month. He will not be able to mail desiccated thyroid. Please contact his office about this option. Patients with a subpotent lot of NP thyroid can have their pharmacy switch them to an unaffected lot at no charge. Patients do not need to contact Dr. Friedman, but if you have any questions or need to schedule an appointment with Dr. Friedman, please email us at mail@goodhormonehealth.com or schedule an appointment on his website at www.goodhormonehealth.com.

According to the recall, if a patient receives a sub-potent tablet, hypothyroid symptoms may not be controlled. To date, there have been no reports of adverse events related to this recall. Patients who have had an adverse event should contact RLC Labs. RLC Labs advised that patients should talk to their healthcare professional before they stop taking their Nature-Throid and WP Thyroid medicine. Consumers with questions about the recall can email RLC at recall@rlclabs.com or RLC Customer Service (877) 797-7997. Patients may return unexpired Nature-Throid and WP Thyroid tablets to their pharmacy who are legally required to refund the cost of the tablets. Currently no lots of Nature-Throid and WP Thyroid tablets are commercially available, so a replacement with the same product is not an option. It is unknown how long it will be before Nature-Throid and WP Thyroid become commercially available. Dr. Friedman has several comments about this recall. This is the second recall of desiccated thyroid as some lots of NP thyroid were recalled in May 2020. Dr. Friedman sees this as unfortunate, but still believes desiccated thyroid is a good option for patients with hypothyroidism. Secondly, the “subpotent” Nature-Throid and WP Thyroid pills are only slightly less potent than stated in that only a few lots are between 87% and 90% of the T4 and T3 levels.
