Low Oxytocin Levels Linked to Reduced Empathy

Posted on November 12, 2016 by MaryO

People suffering from low levels of oxytocin perform worse on empathy tasks, according to new research presented at the 2016 Society for Endocrinology annual conference.

The research suggests that hormone replacement could improve the psychological well-being of those living with low levels, according to researchers at the University of Cardiff.

Oxytocin is often referred to as the “love hormone” due to its role in human behavior, including sexual arousal, recognition, trust, anxiety, and mother-infant bonding. It is produced by the hypothalamus — an area of the brain that controls mood and appetite — and stored in the pituitary gland.

For the study, researchers investigated empathic behavior in people who they suspected of having reduced oxytocin levels due to one of two medical conditions caused in response to pituitary surgery.

The study assessed 20 people with cranial diabetes insipidus (CDI). In CDI, the body has reduced levels of ADH, a chemical also produced in the hypothalamus and structurally very similar to oxytocin.

The researchers also assessed 15 people with hypopituitarism (HP), a condition in which the pituitary gland does not release enough hormones.

These two patient groups were compared to a group of 20 healthy people.

The researchers gave all participants two tasks designed to test empathy, both relating to the recognition of emotional expression. They also measured each group’s oxytocin levels and found that the 35 CDI and HP participants had slightly lower oxytocin compared to the healthy people. The researchers noted that a larger sample is required to establish statistical significance.

The researchers also discovered that the CDI and HP groups performed significantly worse on empathy tasks, compared to the healthy control group. In particular, CDI participants’ ability to identify expressions was predicted by their oxytocin levels — those with the lowest levels of oxytocin produced the worst performances, according to the study’s findings.

“This is the first study which looks at low oxytocin as a result of medical, as opposed to psychological, disorders,” said Katie Daughters, lead researcher. “If replicated, the results from our patient groups suggest it is also important to consider medical conditions carrying a risk of low oxytocin levels.”

“Patients who have undergone pituitary surgery, and in particular those who have acquired CDI as a consequence, may present with lower oxytocin levels,” she continued. “This could impact on their emotional behavior, and in turn affect their psychological well-being. Perhaps we should be considering the introduction of oxytocin level checks in these cases.”

The researchers said they hope to expand their study to further replicate and confirm their findings. They added that the study presents only preliminary results, and has not been peer reviewed.

“How can you leave her like this?”

Posted on September 8, 2016 by MaryO

A mother has revealed the anguish her family suffered after her daughter (16), who is in need of brain surgery, was turned away from Beaumont Hospital.

The National Centre for Neurosurgery had no beds or theatre access for nine patients with malignant brain tumours last Friday.
One of the people who was turned away was 16-year-old Chloe Holian from Donegal.

Her mother Caitriona explained to the Anton Savage Show on TodayFM that the road to treatment has been fraught with setbacks.

“I can’t stress how happy I am with the neurosurgeon and his team are there but it seems our consultant’s hands are tied, what am I supposed to do?” she said.

Chloe was diagnosed in July with a recurrence of Cushing’s syndrome, a metabolic disorder which is caused by abnormally high levels of the hormone cortisol in the blood stream.

After being promised treatment in July and then August, the Letterkenny girl was finally admitted on Thursday and was fasting for a procedure on Friday morning when she was told it was cancelled.

“When we got down they told us that they decided to put off the surgery for a couple of days,” said Caitriona.

She was told that the doctors wanted to perform a dexamethasone suppression test first to confirm that Chloe was, in fact, suffering from Cushing’s – despite previous diagnosis revealing that she was.

However, she soon found out that the test couldn’t be performed.

“At 11am someone in scrubs came around to say it wasn’t fair but he had to tell us she won’t be doing the surgery… and she wouldn’t be getting the major test either,” said Caitriona.

She said he was very empathetic of their situation.

“I felt sorry for him having to tell us that news… I asked him ‘how can you leave her like this?’

“He promised that he was going to organise this test himself. It was quite difficult as you need four people in the surgery to do this test, you need the radiographer, neurosurgeon, endocrinologist and anesthetist.”

Unfortunately, an anesthetist was not available for the test.

Caitriona said that Chloe was quite upset at the news. One of the side-effects of her condition is excessive weight gain and the student has gained six stone since last September.

“She had psyched herself up for the surgery,” explained her mother.

“Everybody was around her encouraging her, they threw a party for her before she went because it was a big thing. Chloe has no confidence because she’s put on an extra six stone. She was looking forward to getting her old self back, she just wanted to go and do this operation and get it over and done with.

“For anybody to have a little bit of a weight gain they can be conscious of it but if you’re 16-years-old and you’ve gained six stone and you can’t explain it…”

Caitriona said the family were forced to pack their bags and return to Donegal but, as of today, they have still not received a rescheduled appointment.

The mother-of-three is struggling to juggle home life with trips to Dublin but she said the family’s life is on hold until the tumour is removed.

This is the second time that Chloe has developed Cushing’s, in 2009 she was sent to London for surgery as treatment was not yet available in Ireland.

Patients lives are being threatened by delays, according to the head of the country’s national brain surgery centre. Clinical Director Mohsen Javadpour says people are at risk of dying while they’re waiting for treatment.

Cushing’s syndrome: Pituitary surgery alone is the preferred treatment to improve survival

Posted on July 8, 2016 by MaryO

Background

No agreement has been reached on the long-term survival prospects for patients with Cushing’s disease. We studied life expectancy in patients who had received curative treatment and whose hypercortisolism remained in remission for more than 10 years, and identified factors determining their survival.

Methods

We did a multicentre, multinational, retrospective cohort study using individual case records from specialist referral centres in the UK, Denmark, the Netherlands, and New Zealand. Inclusion criteria for participants, who had all been in studies reported previously in peer-reviewed publications, were diagnosis and treatment of Cushing’s disease, being cured of hypercortisolism for a minimum of 10 years at study entry, and continuing to be cured with no relapses until the database was frozen or death. We identified the number and type of treatments used to achieve cure, and used mortality as our primary endpoint. We compared mortality rates between patients with Cushing’s disease and the general population, and expressed them as standardised mortality ratios (SMRs). We analysed survival data with multivariate analysis (Cox regression) with no corrections for multiple testing.

A Single-Center 10-Year Experience with Pasireotide in Cushing’s Disease: Patients’ Characteristics and Outcome

Posted on April 30, 2016 by MaryO

Pasireotide is the first pituitary-directed drug approved for treating patients with Cushing’s disease (CD). Our 10-year experience with pasireotide in CD is reported here.

Twenty patients with de novo, persistent, or recurrent CD after pituitary surgery were treated with pasireotide from December 2003 to December 2014. Twelve patients were treated with pasireotide in randomized trials and 8 patients with pasireotide sc (Signifor®; Novartis AG, Basel, Switzerland) in clinical practice. The mean treatment duration was 20.5 months (median 9 months; range, 3-72 months).

Urinary free cortisol (UFC) levels mean percentage change (± SD) at last follow-up was-40.4% (± 35.1; range, 2-92%; median reduction 33.3%) with a normalization rate of 50% (10/20). Ten patients achieved sustained normalized late night salivary cortisol (LNSC) levels during treatment. LNSC normalization was associated with UFC normalization in 7/10 patients. Serum cortisol and plasma ACTH significantly decreased from baseline to last follow-up. Body weight decrease and blood pressure improvement during pasireotide treatment were independent from UFC response. Glucose profile worsening was observed in all patients except one. The frequency of diabetes mellitus increased from 40% (8/20) at baseline to 85% (17/20) at last follow-up requiring initiation of medical treatment only in 44% of patients.

Pasireotide treatment was associated with sustained biochemical and clinical benefit in about 60% of CD patients. Glucose profile alteration is a frequent complication of pasireotide treatment; however, it seems to be easy to manage with diet and lifestyle intervention in almost half of the patients.

Tiruchi surgeons treat Pakistan national for pituitary tumour

Posted on February 15, 2016 by MaryO

The patient had discovered his condition by chance in Quetta last year.

A team of city-based surgeons has performed a sophisticated surgery on a young Pakistani national to remove a pituitary tumour.

Bakhtiyar Khan, a 30-year-old Pakistani national from the Talli village in Sibi, Balochistan, underwent the surgery here a few days ago.

The surgery was performed by Dr. T.N. Janakiraman, skull base surgeon and managing director, Royal Pearl Hospital and Research Institute, Dr. Uday Chanukya, Dr. Prayatna Kumar, skull base surgeons, and Dr. Balamurugan, anaesthesiologist.

The tumour, in the cavernous sinus — a large collection of thin-walled veins creating a cavity bordered by the temporal bone of the skull and the sphenoid bone in the head, was removed through endoscopic surgery.

“Normally surgeons go through the skull and brain to excise the tumour with the help of surgical microscopic glasses. But this doesn’t ensure the removal of the entire tumour, which is why radiation is recommended after the operation,” Dr. Janakiraman told The Hindu .

“In Bakhtiyar’s case, the tumour had gone into the cavernous sinus. We used his nasal cavity as the entry point, and brought the tumour out through the nose as well. This is a scar-less keyhole surgery that ensures complete excision and doesn’t require us to make a new opening in the skull,” he added.

Dr. Janakiraman, who was trained in the procedure by internationally renowned neurosurgeon Dr. Amin Kassam in the U.S. 10 years ago, has been doing the procedure for the past nine years in Tiruchi.

For the patient’s elder brother, Sardar Khan, the experience has been both exhausting yet exhilarating. A file clerk at the local health centre in Sibi, the Khan brothers had taken their father, who is paralysed, to a doctor in Quetta last year, when the physician there suggested that it was Mr. Bakhtiyar who needed medical attention urgently. “None of us knew that he was unwell,” recounted Mr. Sardar. “We were advised by neurosurgeon Dr. Asghar Khan to seek help in India immediately. I couldn’t believe that I, who had never left my village to see even Lahore or Karachi, had to go to India.”

In a process that took three to six months, Mr. Sardar convinced Mr. Bakhtiyar and his other siblings (they are eight brothers and two sisters) to get ready to meet Dr. Janakiraman, besides applying for passports and organising visas.

The brothers took the Samjhauta Express from Wagah to Delhi on January 31. The Tamil Nadu Sampark Kranti Express brought them to Tiruchi after a 46-hour journey. As a humanitarian gesture, the hospital has waived all fees (in the range of Rs. 1 to 3 lakhs), except the cost of medicines.

“I’m feeling much better now, and my eyesight has improved,” said Mr. Bakhtiyar Khan. After a few days of observation and a final MRI scan, he will be free to travel back home with his brother.

Said a gratified Mr. Sardar: “I haven’t seen much of India, or even of Tiruchi, but to me, Dr. Janakiraman and his team are India. I’d like to thank all my new friends in India for taking such good care of me and my brother.”
