7 Things Your Hair Reveals About Your Health

Posted on January 20, 2022 by MaryO

Your hair can tell you and your doctor if you are stressed, have a nutritional deficiency, thyroid problem, or other health issues. Here are seven key things to look for in your hair.

You probably think about your hair every day: worrying about a bad day, enjoying a good blow-dry, or wondering if you have to try the new style you noticed in your favorite celebrity. But you may be missing the clues your hair reveals about your health. Research shows that changes in the look, texture, or thickness of your hair can be signs of underlying health issues. Here’s how to tell if your hair changes are due to a health condition, genetics, stress, or a nutritional deficiency.

1 Stress (and genes) can cause you to turn gray

Anyone who has observed the hairstyle changes of a President of the Republic from one campaign to another has noticed that stress seems to cause hair to turn white. A mouse study published in the journal Nature suggests that chronic stress may actually contribute to white hair by causing DNA damage and reducing the number of pigment-producing cells in hair follicles. Stress can also lead to hair loss.

Another type of stress, known as oxidative stress, can also play a role in white hair. Oxidative stress can affect pigment-producing cells. Turning gray is actually a completely natural part of aging because hair follicles produce less color as you age. Your genes also play a role in when your hair turns gray. Ask your parents how old they were when they first saw the signs of silvering, and you might do the same. In fact, a study published in March 2016 in the journal Nature Communications was the first to identify the gene responsible for white hair.

2 brittle hair could be a sign of Cushing’s syndrome

Brittle hair is one of the symptoms of Cushing’s syndrome, which is a rare condition caused by excess cortisol, the main hormone body stress. But, there are many other, more obvious symptoms of Cushing’s syndrome, including high blood pressure, fatigue, and back pain. Treatment for Cushing’s syndrome may involve changing the dose of medication that may be causing the condition, such as glucocorticoids, which are steroids used to treat inflammation caused by various diseases.

3 Thinning hair may be a sign of thyroid disease

People with hypothyroidism, a condition that occurs when the thyroid gland does not produce enough thyroid hormones, may notice increased hair loss and change in hair appearance. About 4.6% of the population aged 12 years and older have hypothyroidism, although most cases are mild. Hypothyroidism can lead to thinning hair and other symptoms, such as fatigue, intolerance to cold, joint pain, muscle aches, puffy face and weight gain. A thyroid stimulating hormone (TSH) test can diagnose the condition, and treatment involves taking thyroid medication.

In addition to thinning hair, some thyroid disorders put you at risk for risk of autoimmune hair loss called alopecia areata. This type of hair loss causes round patches of sudden hair loss and is caused by the immune system attacking the hair follicles.

4 Hair loss can be a sign of anemia

If you suddenly notice a lot more hair in your hairbrush or on the floor of your shower, it may be a sign that your body has low iron stores, or anemia , and may warrant testing. This is another blood test we do when you complain of hair changes. Vegetarians or women with heavy periods increase their risk that hair changes are due to iron deficiency.

It is unclear why iron deficiency can lead to hair loss. hair, but iron is essential for many biological and chemical reactions, perhaps including hair growth. Hair loss can also occur (temporarily) with sudden changes in estrogen levels and is often noticed after pregnancy or stopping birth control pills.

5 The loss of hair could indicate protein deficiency

Protein is essential for hair health and growth (a lack of protein has been linked to hair thinning and hair loss ). Protein deficiency is not a problem for most people. Most adults need 0.8 grams of protein per kilogram of body weight. Good sources of protein include low-fat Greek yogurt, chickpeas, and chicken breast. People who have gastrointestinal difficulties or who have just had gastric bypass surgery may have problems digesting protein. These special situations will need to be managed with the help of your doctor. But most cases of thinning hair, even in women, are probably due to genetics.

6 White or yellow flakes can mean you have dandruff

Yellow or white flakes in your hair, on your shoulders and even in your eyebrows are a sign of dandruff, a chronic scalp condition. Dandruff is usually not a sign of a health problem and can be treated with specialized over-the-counter or prescription shampoos.

One of the most common causes of dandruff is a medical condition called seborrheic dermatitis. People with seborrheic dermatitis have red, oily skin covered in white or yellow scales. A yeast-like fungus called malassezia can also irritate the scalp. Insufficient shampoo, sensitivity to hair care products, and dry skin can also cause dandruff. (Dandruff is usually more severe in the winter, when indoor heating can make skin drier).

7 Damaged hair can mask other health issues

Although hair can reveal your condition, women more often complain about the damage caused by hair coloring and heat treatment. Excessive heat, from daily use of a flat iron or blow-drying, can certainly damage your hair, making it dry, brittle and difficult to maintain. Best not to use more than one hot tool per day (occasional double heat treatment is okay, but not daily). When applying heat to your hair, always use products with protective ingredients. Serums and shine drops tend to have hair-preserving qualities when using direct and indirect heat.

‘Benign’ Adrenal Gland Tumors Might Cause Harm to Millions

Posted on January 8, 2022 by MaryO

Millions of people are at increased risk of type 2 diabetes and high blood pressure and don’t even know it, due to a hidden hormone problem in their bodies.

As many as 1 in 10 people have a non-cancerous tumor on one or both of their adrenal glands that could cause the gland to produce excess amounts of the stress hormone cortisol.

Up to now, doctors have thought that these tumors had little impact on your health.

But a new study out of Britain has found that up to half of people with these adrenal tumors are secreting enough excess cortisol to raise their risk of diabetes and high blood pressure.

Nearly 1.3 million adults in the United Kingdom alone could suffer from this disorder, which is called Mild Autonomous Cortisol Secretion (MACS), the researchers said.

Anyone found with one of these adrenal tumors should be screened to see if their health is at risk, said senior researcher Dr. Wiebke Arlt, director of the University of Birmingham Institute of Metabolism and Systems Research in England.

“People who are found to have an adrenal tumor should undergo assessment for cortisol excess and if they are found to suffer from cortisol overproduction they should be regularly screened for type 2 diabetes and hypertension and receive treatment if appropriate,” Arlt said.

These tumors are usually discovered during imaging scans of the abdomen to treat other illnesses, said Dr. André Lacroix, an endocrinologist at the University of Montreal Hospital Center, who wrote an editorial accompanying the study. Both were published Jan. 4 in the Annals of Internal Medicine.

Adrenal glands primarily produce the hormone adrenaline, but they are also responsible for the production of a number of other hormones, including cortisol, Lacroix said.

Cortisol is called the “fight-or-flight” hormone, and can cause blood sugar levels to rise and blood pressure to surge — usually in response to some perceived bodily threat.

Previous studies had indicated that about 1 in 3 adrenal tumors secrete excess cortisol, and an even lower number caused cortisol levels to rise so high that they affected health, researchers said in background notes.

But this new study of more than 1,300 people with adrenal tumors found that previous estimates were wrong.

About half of these patients had excess cortisol due to their adrenal tumors. Further, more than 15% had levels high enough to impact their health, compared to those with truly benign tumors.

MACS patients were more likely to be diagnosed with high blood pressure, and were as much as twice as likely to be on three or more blood pressure medications.

They also were more likely to have type 2 diabetes, and were twice as likely to require insulin to manage their blood sugar, the study found.

“This study clearly shows that mild cortisol production is more frequent than we thought before, and that the more cortisol you produce, the more likely to you are to have consequences such as diabetes and hypertension,” Lacroix said.

About 70% of people with MACS were women, and most were of postmenopausal age, the researchers said.

“Adrenal tumor-related cortisol excess is an important previously overlooked health issue that particularly affects women after the menopause,” Arlt said.

Lacroix agreed that guidelines should be changed so that people with adrenal tumors are regularly screened.

“Everybody who is found to have an adrenal nodule larger than 1 centimeter needs to be screened to see if they’re producing excess hormone or not,” he said. “That’s very clear.”

A number of medications can reduce cortisol overproduction or block cortisol action, if an adrenal tumor is found to be causing an excess of hormone.

People with severe cortisol excess can even have one of their two adrenal glands removed if necessary, Lacroix said.

“It is quite possible to live completely normally with one adrenal gland,” he said.

Sparrow Pharmaceuticals Hopes To Change The Future Of Endocrinology

Sparrow Pharmaceuticals is an emerging biopharma company on a mission to help patients suffering from an excess of corticosteroids, with a focus on Cushing’s syndrome, autonomous cortisol secretion (ACS), and polymyalgia rheumatica (PMR).

Cushing’s and ACS are both caused by an excess of cortisol produced by tumors. Patients with Cushing’s can present physically with a fatty hump between their shoulders, a rounded face, and pink or purple stretch marks on their skin. Cushing’s syndrome and ACS can both result in high blood pressure, bone loss, type 2 diabetes, weight gain, and mood, cognition, and sleep disorders. Any of those symptoms may be side effects for patients with conditions such as PMR who rely on long-term treatment with corticosteroid medications such as prednisone.

“Cushing’s syndrome impacts around 20,000 patients in the U.S. alone,” says David Katz, Chief Scientific Officer for Sparrow. “Approximately 50% of those patients can be cured by surgery, but some will develop another tumor years later. ACS is an under-recognized condition, but it may affect up to 3 million patients in the U.S. There are also around 2 million people in the U.S. who rely on long-term use of corticosteroid medications to control autoimmune diseases and other conditions.”

The treatments being developed by Sparrow are based on recognition that cortisol and corticosteroid medications are activated in certain tissues such as the liver, bone, fat, and brain, where in excess they act to cause toxicity. The company’s investigational drugs inhibit HSD-1, the enzyme responsible for that activation.

Sparrow is about to launch a Phase 2 trial for Cushing’s syndrome. In early 2022 the company will also begin two additional Phase 2 trials for ACS and PMR, a common autoimmune disease in elderly patients. PMR is an arthritic syndrome characterized by a phenomenon known as claudication, which means the more you use a limb, the more it hurts and the harder it is to use. “For example, the more a PMR patient walks, the more painful and stiff their legs will become,” says Katz. “If they’re trying to do anything with their arms, the arms will get stiffer and more painful. The disease is pretty debilitating in terms of physical function. The only approved treatment for PMR is steroids, which have side effects such as diabetes, hypertension, osteoporosis, and fractures.”

Unknown Clinical Challenges

Katz is excited about the clinical trials for ACS and PMR because no sizable interventional trials have been reported in either of those conditions.

“We’re going into a completely new area, and we don’t know what we’re going to encounter in terms of patient recruitment and retention,” says Katz. “There is also no strong precedent for how to get approval for a drug in these conditions. The only treatment indicated for PMR is steroids, and that came without any efficacy clinical trials. There are no drugs approved for ACS. It’s hard to anticipate the challenges we will face when we are in an area that is very new.”

Patient centricity is a topic that is very important to Katz, and he spends a lot of time thinking about how to make trials a more pleasant experience for patients by limiting the burden placed on them. He notes that can sometimes be a difficult trade-off because of the procedures that must be performed to meet regulatory standards.

“In Cushing’s syndrome clinical care and clinical trials, the standard way for someone’s cortisol level to be measured is a 24-hour urine collection,” states Katz. “That involves looking at the amount of cortisol in the urine over a 24-hour period. That collection is inconvenient and burdensome, and the patient must then carry it somewhere to be analyzed.”

Sparrow hopes to shift that collection to a spot urine sample, like what patients would experience during a physical. The patient would urinate into a cup and hand it off to a clinic employee for analysis. The process would be much simpler and less burdensome for the patient. Sparrow will first need to prove that in a clinical trial the spot sample will work as well or better than the 24-hour collection. Subjects in the initial clinical trials will have to contribute the 24-hour collections so that Sparrow can demonstrate that future patients will not need to do so.

The Future of Endocrinology

Katz has a positive outlook on the future of endocrinology. Sparrow’s leading drug candidate, SPI-62, is an oral, small-molecule HSD-1 inhibitor. In four clinical trials, it demonstrated potent targeting of HSD-1 in both the brain and liver, and significantly lowered cortisol levels in the liver. The studies also showed a favorable safety and tolerability profile.

“If we are successful at developing SPI-62, I believe it will change the field of endocrinology,” says Katz. “We aim to shift the focus in Cushing’s syndrome to intracellular cortisol as the main driver of symptoms. What I mean by that is if we find that SPI-62 substantially reduces symptoms and that the degree of inhibition of our target HSD-1 correlates well with clinical improvement, then we can get to a new standard of care. We can potentially get rid of the 24-hour urine collections, which will be a big relief to patients. Additionally, many of today’s drugs have a side effect called adrenal insufficiency, which results when the drugs either reduce cortisol too much or completely block activity. Many of today’s drugs also require frequent monitoring and dose titration to prevent adrenal insufficiency. We believe that with HSD-1 inhibition we might avoid adrenal insufficiency as well.”

Katz is hopeful patients treated with SPI-62 will not require monitoring and dose titration. That proof will take years and lots of clinical trials. Sparrow may also produce the first targeted therapy for ACS. That could improve the recognition of ACS as a prevalent form of hypercortisolism and a substantial cause of morbidity and mortality.

“ACS is probably the most under-recognized condition in endocrinology based on recent epidemiological studies,” adds Katz. “It’s possible that as few as 3% of patients who have ACS actually have a diagnosis.  That is shocking for a condition that is associated with a lot of cardiometabolic and bone morbidity, negative effects on mood and cognition, sleep, and muscle strength, and is associated with excess mortality. We want to bring attention to this condition by bringing out a targeted therapy to treat a spectrum of symptoms by getting to the root cause of them.”

Researchers Report Rare Case of Cushing’s Caused by Bilateral Adrenal Tumors

Posted on July 8, 2019 by MaryO

Cases of adrenocorticotropic hormone (ACTH)-independent Cushing’s syndrome are often caused by unilateral tumors in the adrenal glands, but Indian researchers have now reported a rare case where the condition was caused by tumors in both adrenal glands.

Fewer than 40 cases of bilateral tumors have been reported so far, but an accurate diagnosis is critical for adequate and prompt treatment. Sampling the veins draining the adrenal glands may be a good way to diagnose the condition, researchers said.

The study, “Bilateral adrenocortical adenomas causing adrenocorticotropic hormone-independent Cushing’s syndrome: A case report and review of the literature,” was published in the World Journal of Clinical Cases.

Cushing’s syndrome, a condition characterized by excess cortisol in circulation, can be divided into two main forms, depending on ACTH status. Some patients have tumors that increase the amount of ACTH in the body, and this hormone will act on the adrenal glands to produce cortisol in excess. Others have tumors in the adrenal glands, which produce excess cortisol by themselves, without requiring ACTH activation. This is known as ACTH-independent Cushing’s syndrome.

Among the latter, the disease is mostly caused by unilateral tumors — in one adrenal gland only —  with cases of bilateral tumors being extremely rare in this population.

Now, researchers reported the case of a 31-year-old Indian woman who developed ACTH-independent Cushing’s syndrome because of tumors in both adrenal glands.

The patient complained of weight gain, red face, moon face, bruising, and menstrual irregularity for the past two years. She recently had been diagnosed with high blood pressure and had started treatment the month prior to the presentation.

A physical examination confirmed obesity in her torso, moon face, buffalo hump, thin skin, excessive hair growth, acne, swollen legs and feet, and skin striae on her abdomen, arms, and legs.

Laboratory examinations showed that the woman had an impaired tolerance to glucose, excess insulin, and elevated cortisol in both the blood and urine. Consistent with features of Cushing’s syndrome, cortisol levels had no circadian rhythm and were non-responsive to a dexamethasone test, which in normal circumstances lowers cortisol production.

Because ACTH levels were within normal levels, researchers suspected an adrenal tumor, which led them to conduct imaging scans.

An abdominal computed tomography (CT) scan showed adrenal adenomas in both adrenal glands (right: 3.1 cm × 2.0 cm × 1.9 cm; left: 2.2 cm × 1.9 cm × 2.1 cm). A magnetic resonance imaging (MRI) scan showed that the pituitary gland (which normally produces ACTH) was normal.

To determine whether both adrenal tumors were producing cortisol, researchers sampled the adrenal veins and compared their cortisol levels to those of peripheral veins. They found that the left adrenal gland was producing higher amounts of cortisol, thought the right adrenal gland was also producing cortisol in excess.

“Our case indicates that adrenal vein [blood] sampling might be useful for obtaining differential diagnoses” in cases of Cushing’s syndrome, researchers stated. Also, they may help design a surgical plan that makes much more sense.”

The tumors were surgically removed — first the left, and three months later the right — which alleviated many of her symptoms. She also started prednisolone treatment, which helped resolve many disease symptoms.

“Bilateral cortisol-secreting tumors are a rare cause of Cushing’s syndrome,” researchers said. So when patients present bilateral adrenal lesions, “it is crucial to make a definitive diagnosis before operation since various treatments are prescribed for different causes,” they said.

The team recommends that in such cases the two tumors should not be removed at the same time, as this approach may cause adrenal insufficiency and the need for glucocorticoid replacement therapy.

Post-traumatic Stress Symptoms Common in Cushing’s Patients Before Surgery

Posted on June 29, 2019 by MaryO

Patients with Cushing’s disease may develop post-traumatic stress symptoms, which are generally resolved once they undergo surgery to remove the tumor, but can persist in some cases, a study shows.

The study, “Posttraumatic stress symptoms (PTSS) in patients with Cushing’s disease before and after surgery: A prospective study,” was published in the Journal of Clinical Neuroscience.

Cushing’s disease is an endocrine disorder characterized by excess secretion of the adrenocorticotropic hormone (ACTH) by a pituitary adenoma (tumor of the pituitary gland). This leads to high levels of cortisol, a condition known as hypercortisolism.

Chronic hypercortisolism is associated with symptoms such as central obesity, buffalo hump, body bruising, muscle weakness, high blood pressure, high blood sugar, and weak bones.

Additionally, patients can develop psychiatric disorders including depression, anxiety, and cognitive dysfunction, all of which contribute considerably to a lower health-related quality of life.

Depression and anxiety rates are particularly high in Cushing’s disease patients, with 54% of them experiencing major depression and 79% having anxiety.

Due to the significant impact of psychological factors in these patients, they may be susceptible to post-traumatic stress symptoms (PTSS). But more information on this phenomenon in these patients is still needed.

To address this lack of data, a group of Chinese researchers conducted a prospective study to investigate the occurrence, correlated factors, and prognosis of PTSS in patients with Cushing’s disease.

A total of 49 patients newly diagnosed with Cushing’s disease who underwent transsphenoidal removal of the tumor as their first-line treatment were asked to participate in this study. Another group of 49 age- and sex-matched healthy individuals were included as controls.

PTSS was measured using the Impact of Event Scale-Revised (IES-R), depression/anxiety were measured using the Hospital Anxiety and Depression scale (HADS), and quality of life was measured using the 36-item short-form (SF-36). These parameters were measured before surgery, and then at six and 12 months after the procedure.

Before surgery, 15 patients (30.6%) had PTSS. These patients also had higher cortisol levels, worse levels of depression/anxiety, and worse quality of life scores than those without PTSS.

While most of the patients recovered after the operation, there were five (33.3%) for whom PTSS persisted for more than a year.

Additionally, one patient who had a recurrence of Cushing’s disease developed PTSS between six and 12 months after the first surgery.

PTSS severity showed consistent improvement after surgery, which was correlated with better depression/anxiety scores and psychological aspects of the SF-36. However, Cushing’s disease patients in remission still performed worse than healthy individuals concerning their physical and mental health.

Therefore, “patients with [Cushing’s disease] can develop PTSS, and they may persist for over a year even after successful surgery. Combined psychological intervention is advised for these patients,” the researchers concluded.
