A TEENAGER with complex special needs who died in hospital suffered a failure in basic medical communication, an inquest heard today.

Robin Brett, 18, of Blackmore Close, died in June 2014 in the Great Western Hospital after being admitted with chronic constipation and vomiting.

After a blood test indicated a raised white blood cell count, Robin went into cardiac arrest and died.

He had congenital adrenal hyperplasia (CAH) a metabolic disease and genetic defect of the adrenal gland and learning difficulties. He required daily care and medications.

Robin’s parents listed a string of errors they believe contributed to his death including failure to give him his regular medications, infrequent observations and the lack of regular and vital cortisol injections.

His heartbroken mother, Teresa, told the inquest in Salisbury that she had told hospital staff to give Robin an emergency dose of cortisol, which was not topped up after the recommended four hours.

She said: “I asked them to give him cortisol after I noticed he was becoming clammy and had a headache which is a sign of adrenal distress, I was just about to with the syringe in my hand when it was done and he instantly perked up.

 “But this wasn’t done again after four hours and I don’t know why.”

GWH staff nurse Hannah Porte who cared for Robin on his admission said she had concerns about his “alarmingly” high pulse rate when she did observations.

“I spoke with a doctor who assured me that because he had a pre-existing condition it wasn’t of great concern. That is our protocol and I felt comforted and reassured when they said that,” she said.

Robin was described as “rocking backwards and forwards and retching “ shortly before his cardiac arrest.

Mum Teresa broke down as she recalled her “sociable and friendly” son’s decline.

“He asked me to turn his DVD player off which was out of character in itself and he was clammy. All of a sudden he wasn’t breathing,” she said,

Registrar Fahreyer Alam, who examined Robin upon admission, said he could not provide an explanation as to why steroidal drugs were prescribed but not administered to Robin.

“They was nothing about his condition on examination which would link to adrenal crisis,” he said,

“The drugs were written on the drug chart and I cannot say why they were not given to him.”

Dr Alam said he had set an observation schedule of every two hours which he had articulated to nurses, and was not observed.

“All I can is there is an element of trust in the nurses and in a busy department we do have to relay things verbally and that is what you do,” he said.

When questioned by assistant coroner Dr Claire Balysz, Dr Alam said the effect of the seven week constipation may have put pressure on Robin’s vital organs.

“His heart and lungs were smaller than average and slightly underdeveloped. The faecal impaction made his colon stretch, it may have impacted his lungs and his heart and that is something the post mortem found,” he said.

Dr Alam and nurse Porte agreed that more was being done within the trust to improve the accuracy and accessibility of patient records, including a new observation system and the use of electronic prescribing and administration (EPMA) system.

Cushing’s Syndrome

Posted on October 3, 2015 by MaryO

The Seven Dwarves of Cushing's

 

Posted Oct. 1st, 2015 by Clare Rowson

Q: Would you please explain Cushing’s disease. How is it diagnosed? What are the symptoms?

A: Cushing syndrome results from excess levels of the hormone cortisol. It is produced in various glands, usually the adrenal that is situated above the kidneys on both sides, and the pituitary gland, which is in the centre of the brain.

Cortisol also regulates the way fats, carbohydrates and proteins are turned into usable forms of energy. These glands produce other hormones that affect things such as blood pressure and the body’s response to stress.

Cortisol may be added from outside the body by taking medications such as prednisone, often used for the control of chronic inflammatory or autoimmune diseases like lupus or rheumatoid arthritis.

Prednisone is also used for the treatment of acute illnesses such as severe allergies. Poison ivy is often treated this way.

Women in the last three months of pregnancy also have increased blood levels of cortisol and may temporarily display some of symptoms of Cushing’s syndrome.

Any problem with the pituitary gland, the nearby hypothalamus in the brain or adrenals can lead to Cushing’s syndrome. The most common is a benign tumour of the pituitary gland known as a pituitary adenoma.

This type of tumour may produce an excessive amount of a stimulating hormone known as ACTH, which in turn activates the hormones in the adrenal glands. On rare occasions, some types of lung or thyroid cancer can also behave in a similar way.

The most obvious sign of Cushing’s disease is marked weight gain, mostly in the abdomen, face and neck, while the arms and legs remain relatively thin.

As the skin in these areas becomes thinner, there may be purple coloured stripes or stretch marks. Women may also lose their periods and grow facial or body hair.

Blood pressure is usually high and sufferers feel weak and tired.

Cushing’s disease is diagnosed by measuring the amount of cortisol in a person’s urine during a 24 hour period.

If there is a tumour it will require surgical removal. If Cushing’s syndrome is a result of prescribed medication, the dosage can be reduced gradually or another type of medication can be tried. Prednisone must never be suddenly discontinued or the person’s blood pressure could drop dramatically, which could be serious and potentially fatal.

Metopirone effective treatment for hypercortisolemia in Cushing’s syndrome

Posted on September 15, 2015 by MaryO

Hypercortisolemia in Cushing’s syndrome can be controlled with Metopirone therapy, according to recent study findings published in The Journal of Clinical Endocrinology & Metabolism.

John Newell-Price, PhD, FRCP, of the University of Sheffield in the United Kingdom, and colleagues evaluated 195 patients with Cushing’s syndrome to determine the effect of Metopirone (metyrapone, HRA Pharma) on the control of excess cortisol. Cushing’s syndrome was most commonly Cushing’s disease (n = 115), followed by ectopic adrenocorticotropic hormone (ACTH; n = 37), benign adrenal disease (n = 30), adrenocortical carcinoma (n = 10), ACTH-independent macronodular adrenal hyperplasia (n = 2) and primary pigmented nodular adrenal hyperplasia (n = 1).

The biochemical parameters of activity of Cushing’s syndrome were measured by mean serum cortisol day-curve (target, 150-300 nmol/L), early morning serum cortisol and 24-hour urinary free cortisol.

Most participants received monotherapy (n = 164) and had significant improvements in excess cortisol during treatment. Significant improvements were revealed from first to last review for cortisol day-curve, early morning cortisol and 24-hour urinary free cortisol.

At last review, 55% of participants who had cortisol day-curve, 43% who had urinary free cortisol, 46% who had early morning cortisol less than 331 nmol/L and 76% who had early morning cortisol less than the upper limit of normal/600 nmol/L achieved control.

The median final dose of metyrapone was 1,375 mg among those with Cushing’s disease, 1,500 mg among those with ectopic ACTH, 750 mg among those with benign adrenal disease and 1,250 among those with adrenocortical carcinoma.

Twenty-five percent of participants experienced adverse events, with the most common being mild gastrointestinal upset and dizziness. Most of the adverse events occurred within 2 weeks of initiation or dose increase and were reversible.

“Overall more than 80% of patients showed an improvement in levels of circulating cortisol with over 50% achieving biochemical eucortisolemia when on monotherapy when assessed by the stringent criterion of control on a [cortisol day-curve],” the researchers wrote. “It is likely that additional therapies were added because of the severity of disease and clinician preference, but the retrospective and multicenter nature of our study precludes a formal assessment of this. Furthermore, our data support that metyrapone monotherapy is an effective treatment for hypercortisolemia either before or after surgical intervention to the primary cause of [Cushing’s syndrome].” – by Amber Cox

Endocrine Society Releases Guidelines on Treatment of Cushing’s Syndrome

Posted on August 26, 2015 by MaryO

To lessen the risk for comorbidity and death, the Endocrine Society’s newly published guidelines on the treatment of Cushing’s syndrome focus on surgical resection of the causal tumor with the goal of normalizing cortisol levels. Furthermore, there is increased emphasis on individualizing treatment options when choosing a second-line treatment.

In July 2015, the Endocrine Society published treatment guidelines to assist endocrinologists in appropriately initiating treatment or referring patients with Cushing’s syndrome to treatment. A task force of experts compiled evidence from systematic reviews and graded the strength of the recommendations.

“We hope that it will lead to improved treatment of comorbidities both before and after definitive treatment of the syndrome, and to increased individualization of patient treatment,” said chair of the task force Lynnette Nieman, MD, who is chief of the Endocrinology Consultation Service at the National Institutes of Health Clinical Center.

“There are two new drugs that were approved in 2012, and so I think that is what prompted the review. Still, medications are not the first line of treatment, but we have some new therapeutic options, and I think the idea was to help people understand where to use them,” Julie Sharpless, MD, assistant professor and director of the UNC Multidisciplinary Pituitary Adenoma Program, told Endocrinology Advisor.

“The primary treatment is surgical resection of the causal tumor(s). If that cannot be done (because the tumor is occult or metastatic) or is not successful, then the choice of secondary treatment should be individualized to the patient. The comorbidities of Cushing’s syndrome, for example hypertension and diabetes, should be treated separately as well,” Nieman said.

For example, the guidelines recommend surgical removal of the causative lesion, with the exception of cases which are unlikely to cause a drop in glucocorticoids or in patients who are not surgical candidates.

Likewise, in patients with benign unilateral adrenal adenoma, adrenalectomy by an experienced surgeon has a high rate of cure in children and adults. Because of the poor prognosis associated with adrenal carcinoma, the guidelines highlight the need for complete resection and possibly medical treatment to stabilize cortisol levels.

Other first-line treatment options include recommending surgical resection of ectopic ACTH-secreting tumors; referring to an experienced pituitary surgeon for transsphenoidal selective adenomectomy; treatments to block hormone receptors in bilateral micronodular adrenal hyperplasia; and surgical removal in bilateral adrenal disorders.

The elevated mortality rate seen in patients with Cushing’s syndrome is due to infection, venous thrombosis and cardiovascular disease (CVD). Appropriately lowering cortisol levels improves hypertension, insulin resistance, dyslipidemia and obesity in patients with Cushing’s syndrome. Therefore, the guidelines highlight the need for restoring cortisol levels and treating the associated comorbidities.

Nevertheless, the task force specifically recommends against treatment without an established diagnosis or when there are no signs of Cushing’s syndrome and hypothalamic-pituitary-adrenal laboratory studies are borderline.

In patients who are not surgical candidates or in cases of noncurative resection, the decision on whether to consider second-line treatment options such as medical therapy, radiation, bilateral adrenalectomy or repeat transsphenoidal surgery should be based on several factors. For instance, the guidelines recommend taking into consideration location and size of the tumor, patient desires, goals of treatment and level of biochemical control.

The guidelines note medical therapy should be based on cost, efficacy and individualization of treatment. Endocrinologists can approach medical therapy with a goal of establishing normal cortisol levels or reducing cortisol levels to very low levels and replacing to achieve desired levels.

Remission in Cushing’s syndrome is associated with notable improvement; however, long-term follow-up is recommended for osteoporosis, CVD and psychiatric conditions.

After treatment, patients may experience reductions in weight, blood pressure, lipids and glucose levels that may allow reduction or discontinuation of medications. Even so, patients with a history of Cushing’s syndrome tend to have higher rates of hypertension, hyperlipidemia and diabetes. Likewise, rates of myocardial infarction are higher in this population, further emphasizing the need for treatment and management of diabetes and hypertension.

Sharpless highlighted that Cushing’s syndrome is rare.

“There are multiple studies that have shown that patients do better when they are treated in a specialty center where people see a lot of cases of this. So in that sense, treatment is not usually going to fall to the general practitioner,” she said.

She continued that the guidelines are helpful and provide guidance to endocrinologist who “can’t readily refer their patient to a pituitary center.”

Sharpless went on to describe the multidisciplinary care involved in Cushing’s syndrome including endocrinologists, neurosurgeons, radiologists, counselors and radiation oncologist.

“When the care is complicated, you want to ensure all of your providers have reviewed your case together and figured out the best plan.”

The guidelines were co-sponsored by the European Society of Endocrinology. Nieman received salary support for her work on the manuscript from the Intramural Research Program of the Eunice Kennedy Shiver Institute of Child Health and Human Development. Members of the task force reported multiple disclosures.

Roundup may cause potentially fatal ‘adrenal insufficiency’

Posted on August 22, 2015 by MaryO

IMPORTANT!  A new study finds that the Roundup herbicide disrupts the hormonal system of rats at low levels at which it’s meant to produce no adverse effects. By the same mechanism It may be causing the potentially fatal condition of ‘adrenal insufficiency’ in humans.

Monsanto’s glyphosate-based herbicide Roundup is an endocrine (hormone) disruptor in adult male rats, a new study shows.

The lowest dose tested of 10 mg/kg bw/d (bodyweight per day) was found to reduce levels of corticosterone, a steroid hormone produced in the adrenal glands. This was only one manifestation of a widespread disruption of adrenal function.

No other toxic effects were seen at that dose, so if endocrine disruption were not being specifically looked for, there would be no other signs that the dose was toxic. However a 2012 study detected a 35% testosterone down-regulation in rats at a concentration of 1 part per million.

In both studies endocrine disruption was detected at the lowest level tested for, so we don’t know if, when it comes to endocrine disruption, there are ‘safe’ lower doses of Roundup. In technical parlance, this means that no NOAEL (no observed adverse effect level), was found.

Significantly, the authors believe that the hormonal disruption could lead to the potentially fatal condition know as ‘adrenal insufficiency’ in humans, which causes fatigue, anorexia, sweating, anxiety, shaking, nausea, heart palpitations and weight loss.

“A progressive increase in its prevalence has been observed in humans, while a very few studies relating to xenobiotic exposure and adrenal insufficiency development have been reported”, they write. The increasing levels of Roundup in the environment and food could be “one of the possible mechanisms of adrenal insufficiency.”

How does this level relate to safety limits set by regulators?

One problem with trying to work out how the endocrine disruptive level of 10 mg/kg bw/d relates to how ‘safe’ levels are set by regulators.

The experiment looked at Roundup, the complete herbicide formulation as sold and used, but regulators only look at the long-term safety of glyphosate alone, the supposed active ingredient of Roundup.

Safe levels for chronic exposure to the Roundup herbicide product have never been tested or assessed for regulatory processes. This is a serious omission because Roundup has been shown in many tests to be more disruptive to hormones than glyphosate alone, thanks to the numerous other ingredients it contains to enhance its weed-killing properties.

Given this yawning data gap, let’s for a moment assume that the regulatory limits set for glyphosate alone can be used as a guide for the safe level of Roundup.

The endocrine disruptive level of Roundup found in the experiment, of 10 mg/kg bw/d, is is well above the acceptable daily intake (ADI) set for glyphosate in Europe (0.3 mg/kg bw/d) and the US (1.75 mg/kg bw/d). But this isn’t a reason to feel reassured, since with endocrine effects, low doses can be more disruptive than higher doses.

Another worrying factor is that 10 mg/kg bw/d is well below the NOAEL (no observed adverse effect level) for chronic toxicity of glyphosate: 500 mg/kg bw/d for chronic toxicity, according to the US EPA.

In other words, the level of 500 mg/kg bw/d – a massive 50 times higher than the level of Roundup found to be endocrine disruptive in the experiment – is deemed by US regulators not to cause chronic toxicity.

This experiment shows they are wrong by a long shot. They failed to see toxicity below that level because they failed to take endocrine disruptive effects from low doses into account and industry does not test for them.

Hormone disruption take place at or below ‘no adverse effects’ levels

Interestingly, the NOAEL for glyphosate in industry’s three-generation reproductive studies in rats was much lower than that for chronic toxicity – 30 mg/kg bw/day for adults and 10 mg/kg bw/day for offspring.

However the latter figures – at which no adverse effects should be apparent from glyphosate – are at the same as or higher level than the level of Roundup found to be endocrine disruptive in the new study.

These results therefore show that the reproductive processes of the rats are sensitive to low doses that are apparently not overtly toxic. This in turn suggests that the reproductive toxicity findings are due to endocrine disruptive effects.

Regulatory tests still do not include tests for endocrine disruption from low doses, in spite of the fact that scientists have known about the syndrome since the 1990s.

In the final section of the new study, the researchers discuss its implications. They note that the effects seen in the Roundup-treated rats to the Adrenocorticotropic hormone receptor (ACTH) were similar to adrenal insufficiency in humans:

“The findings that Roundup treatment down regulates endogenous ACTH, is similar to the condition known as adrenal insufficiency in humans. This condition manifests as fatigue, anorexia, sweating, anxiety, shaking, nausea, heart palpitations and weight loss. Chronic adrenal insufficiency could be fatal, if untreated.

“A progressive increase in its prevalence has been observed in humans, while a very few studies relating to xenobiotic exposure and adrenal insufficiency development have been reported. The present study describes one of the possible mechanisms of adrenal insufficiency due to Roundup and suggests more systematic studies, to investigate the area further. “

Claire Robinson of GMWatch commented: “Since no safe dose has been established for Roundup with regard to endocrine disrupting effects, it should be banned.”
