Rare Disease Day 2019

Posted on February 28, 2019 by MaryO

rare disease day

 

Each and every day since 1987,  I tell anyone who will listen about Cushing’s.  I pass out a LOT Cushing’s business cards. My husband also passes out cards and brochures.

Adding to websites, blogs and more which I have maintained continuously since 2000 – at mostly my own expense.

Posting on the Cushing’s Help message boards about Rare Disease Day.  I post there most every day.

Tweeting/retweeting info about Cushing’s and Rare Disease Day today.

Adding info to one of my blogs about Cushing’s and Rare Disease Day.

Adding new and Golden Oldies bios to another blog, again most every day.

Thinking about getting the next Cushing’s Awareness Blogging Challenge set up for April…and will anyone else participate?

And updating https://www.facebook.com/CushingsInfo with a bunch of info today (and every day!)

~~~

Today is Rare Disease Day.

I had Cushing’s Disease due to a pituitary tumor. I was told to diet, told to take antidepressants and told that it was all my fault that I was so fat. My pituitary surgery in 1987 was a “success” but I still deal with the aftereffects of Cushing’s and of the surgery itself.

I also had another Rare Disease – Kidney Cancer, rare in younger, non-smoking women.

And then, there’s the secondary adrenal insufficiency…and growth hormone deficiency…

Sosei Heptares Starts New Clinical Development Program

Posted on February 20, 2019 by MaryO

TOKYO and LONDON, Feb. 20, 2019 /PRNewswire/ — Sosei Group Corporation (“the Company”; TSE: 4565), announces that the first healthy subject has been dosed with a novel small molecule HTL0030310 in a Phase I clinical study, marking the start of a new in-house clinical program targeting endocrine disorders, including Cushing’s disease.

HTL0030310 is a potent and selective agonist of the SSTR5 (somatostatin 5) receptor and the sixth molecule designed by the Company using its GPCR Structure-Based Drug Design (SBDD) platform to enter clinical development.

HTL0030310 has been designed to modulate the excess release of hormones from adenomas (benign tumors) of the pituitary gland. Highly elevated plasma levels of pituitary hormones result in a number of serious endocrine disorders, including Cushing’s Disease. Cushing’s disease is characterized by excessive cortisol release, crucial in regulating metabolism, maintaining cardiovascular function and helping the body respond to stress.

A key design feature of HTL0030310 is its significant selectivity for SSTR5 over SSTR2. This selectivity is expected to improve the balance of efficacy vs. dose-limiting side effects and therefore, presents an opportunity to develop a best-in-class medicine for patients with Cushing’s disease, in particular.

The clinical trial with HTL0030310 is a double-blind, randomised, placebo-controlled first-in-human study in which single ascending subcutaneous doses of HTL0030310 will be administered to healthy male and female adult subjects. The study is being conducted in the UK and will assess the safety, tolerability, pharmacokinetics and pharmacodynamics of HTL0030310 in up to 64 subjects. Preliminary results are expected in the second half of 2019 and will provide a first insight into the effects of HTL0030310 on the control of glucose and other endocrine hormones and the potential to target Cushing’s disease and other endocrine disorders.

Dr. Malcolm Weir, Executive VP and Chief R&D Officer, said: “HTL0030310 is a novel and highly selective molecule, and is the sixth candidate originating from our SBDD platform to advance into human trials. We are not only pleased to begin this new study but also delighted with the productivity of our unique platform to generate attractive candidates targeting GPCRs involved in multiple diseases. These candidates present new prospects for our emerging proprietary pipeline, as well as unique opportunities for partnering, and provide a solid foundation to execute our strategy.”

About Cushing’s disease

Cushing’s disease is a debilitating endocrine disorder caused by the overproduction of the hormone cortisol and is often triggered by a pituitary adenoma (benign tumour) secreting excess adrenocorticotropic hormone (ACTH). Cortisol has a crucial role regulating metabolism, maintaining cardiovascular function and helping the body respond to stress. Symptoms may include weight gain, central obesity, a round, red full face, severe fatigue and weakness, striae (purple stretch marks), high blood pressure, depression and anxiety. Cushing’s disease affects 10-15 million people per year, most commonly adults between 20 to 50 years and women more often than men. The first line and most common treatment approach for Cushing’s disease is surgical removal of the pituitary tumor followed by radiotherapy and drug therapy designed to reduce cortisol production.

Cushing’s Syndrome Patients at More Risk of Blood-clotting Problems After Adrenal Surgery

Posted on February 16, 2019 by MaryO

Cushing’s syndrome patients who undergo adrenal surgery are more likely to have venous thromboembolism — blood clots that originate in the veins — than patients who have the same procedure for other conditions, a study suggests.

Physicians should consider preventive treatment for this complication in Cushing’s syndrome patients who are having adrenal surgery and maintain it for four weeks after surgery due to late VTE onset.

The study, “Is VTE Prophylaxis Necessary on Discharge for Patients Undergoing Adrenalectomy for Cushing Syndrome?” was published in the Journal of Endocrine Society.

Cushing’s syndrome is a condition characterized by too much cortisol in circulation. In many cases, it is caused by a tumor in the pituitary gland, which produces greater amounts of the cortisol-controlling adrenocorticotropic hormone (ACTH). In other cases, patients have tumors in the adrenal glands that directly increase cortisol production.

When the source of the problem is the pituitary gland, the condition is known as Cushing’s disease.

The imbalance in cortisol levels generates metabolic complications that include obesity, high blood pressure, diabetes, and cardiovascular complications. Among the latter, the formation of blood clots in the deep veins of the leg, groin or arm — a condition called venous thromboembolism (VTE) — is higher in both Cushing’s disease and Cushing’s syndrome patients.

VTE is believed to be a result of excess coagulation factors that promote blood clot formation, and is thought to particularly affect Cushing’s disease patients who have pituitary gland surgery.

Whether Cushing’s syndrome patients who have an adrenalectomy — surgical removal of one or both adrenal glands — are at a higher risk for VTE is largely unknown. This is important for post-operative management, to decide whether they should have preventive treatment for blood clot formation.

Researchers at the National Cancer Institute in Maryland did a retrospective analysis of a large group of patients in the American College of Surgeons National Quality Improvement Program database.

A total of 8,082 patients underwent adrenal gland surgery between 2005 and 2016. Data on these patients included preoperative risk factors, as well as 30-day post-surgery mortality and morbidity outcomes. Patients with malignant disease and without specified adrenal pathology were excluded from the study.

The final analysis included 4,217 patients, 61.8% of whom were females. In total, 310 patients had Cushing’s syndrome or Cushing’s disease that required an adrenalectomy. The remaining 3,907 had an adrenal disease other than Cushing’s and were used as controls.

The incidence of VTE after surgery — defined as pulmonary embolism (a blockage of an artery in the lungs) or deep-vein thrombosis — was 1% in the overall population. However, more Cushing’s patients experienced this complication (2.6%) than controls (0.9%).

Those diagnosed with Cushing’s syndrome were generally younger, had a higher body mass index, and were more likely to have diabetes than controls. Their surgery also lasted longer — 191.2 minutes versus 142 minutes — as did their hospital stay – 2.4 versus two days.

Although without statistical significance, the researchers observed a tendency for longer surgery time for patients with Cushing’s syndrome than controls with VTE. They saw no difference in the time for blood coagulation between Cushing’s and non-Cushing’s patients, or postoperative events other than pulmonary embolism or deep-vein thrombosis.

In addition, no differences were detected for VTE incidence between Cushing’s and non-Cushing’s patients according to the type of surgical approach — laparoscopic versus open surgery.

These results suggest that individuals with Cushing syndrome are at a higher risk for developing VTE.

“Because the incidence of VTE events in the CS group was almost threefold higher than that in the non-CS group and VTE events occurred up to 23 days after surgery in patients with CS undergoing adrenalectomy, our data support postdischarge thromboprophylaxis for 28 days in these patients,” the researchers concluded.

Active Cushing’s disease is characterized by increased adipose tissue macrophage presence

Posted on February 10, 2019 by MaryO

Journal of Clinical Endocrinology and Metabolism — Lee IT, et al. | February 07, 2019

Using immunohistochemistry, researchers determined whether adipose tissue (AT) inflammation in humans is associated with chronic endogenous glucocorticoid (GC) exposure due to Cushing’s disease (CD).

Abdominal subcutaneous AT samples were evaluated for macrophage infiltration and mRNA expression of pro-inflammatory cytokines in 10 patients with active CD and 10 age, gender and BMI- matched healthy subjects.

The presence of AT macrophages, a hallmark of AT inflammation, increases chronic exposure to GCs due to CD. AT inflammation can, therefore, be the source of systemic inflammation in these patients, which in turn can contribute to obesity, insulin resistance and cardiovascular disease. In patients with CD, PCR showed no differences in mRNA expression of any analyzed markers.

Faster Adrenal Recovery May Predict Cushing’s Disease Recurrence

Posted on February 9, 2019 by MaryO

A shorter duration of adrenal insufficiency — when the adrenal gland is not working properly — after surgical removal of a pituitary tumor may predict recurrence in Cushing’s disease patients, a new study suggests.

The study, “Recovery of the adrenal function after pituitary surgery in patients with Cushing Disease: persistent remission or recurrence?,” was published in the journal Neuroendocrinology.

Cushing’s disease is a condition characterized by excess cortisol in circulation due to a tumor in the pituitary gland that produces too much of the adrenocorticotropic hormone (ACTH). This hormone acts on the adrenal glands, telling them to produce cortisol.

The first-line treatment for these patients is pituitary surgery to remove the tumor, but while success rates are high, most patients experience adrenal insufficiency and some will see their disease return.

Adrenal insufficiency happens when the adrenal glands cannot make enough cortisol — because the source of ACTH was suddenly removed — and may last from months to years. In these cases, patients require replacement hormone therapy until normal ACTH and cortisol production resumes.

However, the recovery of adrenal gland function may mean one of two things: either patients have their hypothalamus-pituitary-adrenal axis — a feedback loop that regulates ACTH and cortisol production — functioning normally, or their disease returned.

So, a team of researchers in Italy sought to compare the recovery of adrenal gland function in patients with a lasting remission to those whose disease recurred.

The study included 61 patients treated and followed at the Ospedale Maggiore Policlinico of Milan between 1990 and 2017. Patients had been followed for a median of six years (minimum three years) and 10 (16.3%) saw their disease return during follow-up.

Overall, the median time to recovery of adrenal function was 19 months, but while most patients in remission (67%) had not yet recovered their adrenal function after a median of six years, all patients whose disease recurred experienced adrenal recovery within 22 months.

Among those with disease recurrence, the interval from adrenal recovery to recurrence lasted a median of 1.1 years, but in one patient, signs of disease recurrence were not seen for 15.5 years.

Statistical analysis revealed that the time needed for adrenal recovery was negatively associated with disease recurrence, suggesting that patients with sorter adrenal insufficiency intervals were at an increased risk for recurrence.

“In conclusion, our study shows that the duration of adrenal insufficiency after pituitary surgery in patients with CD is significantly shorter in recurrent CD than in the persistent remission group,” researchers wrote.

“The duration of AI may be a useful predictor for CD [Cushing’s disease] recurrence and those patients who show a normal pituitary-adrenal axis within 2 years after surgery should be strictly monitored being more at risk of disease relapse,” they concluded.
