TBD Meeting (3019-19)

LOS ANGELES – In the opinion of Felicia Cosman, MD, the current state of osteoporosis treatment is fraught with clinical challenges.

First, most patients at highest risk for future fractures are not being treated. “In fact, fewer than 25% of patients with new clinical fractures are treated for their underlying disease,” Dr. Cosman, professor of medicine at Columbia University, New York, said at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists (AACE).

“One of the reasons doctors are not treating these patients is that many of them do not have a T-score in the osteoporosis range. There’s a misunderstanding here. A fracture that occurs in people with low bone mass in the setting of minimal trauma – such as a fall from standing height – meets the criteria for the clinical diagnosis of osteoporosis and qualifies a person for being at high risk of more fractures. This is likely because bone weakness or fragility is related not just to quantitative aspects, but also to structural and qualitative aspects that cannot be measured as easily.”

Another problem is that some of the highest-risk patients are those with a vertebral fracture. “However, vertebral fractures are particularly difficult to find and treat because they’re often asymptomatic and we’re not [identifying] these patients,” she said. “Targeted screening [with] spine imaging to find vertebral fractures is probably as important as BMD [bone mineral density] testing.”

To complicate matters, Dr. Cosman said that clinicians and patients “misunderstand the balance between benefits and risks of osteoporosis medications and they don’t consider the risk of not treating the underlying disease. Lastly, there’s little evidence to help guide long-term strategies. Guidelines across medical specialties are incredibly inconsistent. With the exception of guidelines from AACE, the one thing that they’re very consistent about is underrecognizing the value of anabolic therapy for people with severe osteoporosis.”

It is well known that previous bone fracture is the most important risk factor for a future fracture, but the recency of the fracture is also important. In a recent study, researchers followed 377,561 female Medicare beneficiaries with a first fracture for up to 5 years (Osteoporos Int. 2019;30[1]:79-92). They found that at 1 year, the risk of another fracture was 10%. The fracture risk rose to 18% at 2 years, and to 31% at 5 years. “I like to think of this as the osteoporosis emergency,” said Dr. Cosman, co–editor-in-chief of Osteoporosis International. “We need to treat these people right away to prevent more fractures and related disability, morbidity, and mortality.”

According to data from pivotal trials, the anabolic agents teriparatide, abaloparatide, and romosozumab appear to produce more rapid and larger effects against all fractures, compared with even the best antiresorptive agents. “However, comparing across studies can be problematic, because the different populations have varying baseline characteristics and different underlying risk,” Dr. Cosman said. “The protocols and the outcome definitions might be different. It’s better to compare anabolic agents with antiresorptive agents in head-to-head trials, and we now have a few of these.”

Two trials are older studies in which fracture outcomes were not the primary endpoints. One study evaluated a population of patients with glucocorticoid-induced osteoporosis and found that over 18 months, teriparatide reduced vertebral fractures by 90%, compared with alendronate (N Engl J Med. 2007;357[20]:2028-39). The other trial focused on a population of patients with acute, painful vertebral fractures. It found that over 1 year, teriparatide reduced vertebral fractures by 50%, compared with risedronate (Osteoporos Int. 2012;23[8]:2141-50). Two more recent studies compared anabolic and antiresorptive therapies on fracture outcomes as primary endpoints in patients with prevalent fractures. The VERO trial compared teriparatide with risedronate (Lancet. 2018;391[10117]:230-40), and ARCH compared romosozumab with alendronate (N Engl J Med. 2017;377[15]:1417-27).

In VERO, 1,360 patients with a prevalent vertebral fracture were randomized to receive teriparatide or risedronate for 2 years. At 12 months, the proportion of patients with a new vertebral fracture was 3.1% and 6% in the teriparatide and risedronate groups, respectively, a pattern that held true at 24 months (6.4% vs. 12%). The study also showed that the number of nonvertebral fractures was significantly lower in teriparatide-treated patients, compared with those on risedronate. In ARCH, 4,093 postmenopausal women at high risk of fracture were randomized to receive romosozumab or alendronate for 1 year and then followed for a median period of 33 months. At 12 months, the proportion of patients with a new vertebral fracture was 4% and 6.3% in the romosozumab and alendronate groups, respectively, a pattern that held true at 24 months (6.2% vs. 11.9%).

“These trials showed that the antifracture effects are faster and larger with anabolic agents, compared with antiresorptive agents,” Dr. Cosman said. “They also showed that antifracture effects are sustained after transition to antiresorptive therapy.” In ARCH, both nonvertebral and hip fracture incidences were lower in the romosozumab group, compared with the alendronate group.

The trials demonstrated that improving total hip BMD is associated with improved bone strength and resistance to fracture, yet treatment sequence matters. “The greatest BMD gains of the hip are seen when anabolic agents are used first-line, followed by a potent antiresorptive agent,” she said.

Dr. Cosman offered a strategy for patients on potent antiresorptive agents who need anabolic medication. In patients on bisphosphonates, especially with an incident hip fracture or very low hip BMD, consider combination therapy with initiation of teriparatide or abaloparatide, along with an antiresorptive agent. “There are very little data addressing patients on denosumab, but I would suggest perhaps adding teriparatide or abaloparatide in this population, and continuing denosumab,” she said. “That could lead to BMD gain. Switching to romosozumab might also be an option. But, if possible, use an anabolic agent first. The role of anabolic medication for osteoporosis is evolving as evidence continues to suggest superior benefit of anabolic-first regimens for high-risk patients.”

Dr. Cosman disclosed that she has received advising, consulting, and speaking fees from Amgen and Radius. She has received consulting fees from Tarsa and research grants and medication from Amgen.

LOS ANGELES – Recent research, a new test, and upcoming guidelines are providing insight into the diagnosis of adult growth hormone deficiency and the importance of treatment, Kevin C.J. Yuen, MD, FRCP(UK), FACE, told colleagues at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists (AACE).

“The data show that growth hormone replacement is safe and may improve survival,” said Dr Yuen, professor of medicine and medical director at Barrow Neurological Institute Pituitary Center in Phoenix.

Dr. Yuen is chair of the AACE’s growth hormone task force and coauthored both the 2009 and soon-to-be-published 2019 AACE guidelines for the treatment of adult growth hormone deficiency (AGHD).

Updated AGHD guidelines were needed for a variety of reasons, including a greater awareness of the benefits of hormone replacement in these patients and new developments in areas such as testing, he said. The guidelines also are also necessary because of the skepticism about the cost and benefits of AGHD therapy, concerns about the safety of long-term therapy, and the misuse of treatment in certain patients, he added.

On the treatment front, Dr. Yuen said it has become more clear over recent years that patients with AGHD benefit from hormone replacement. Findings from two studies have linked treatment to improvements in exercise capacity (Clin Endocrinol [Oxf]. 2016;85[4]:660-8) and patient quality of life (Eur J Endocrinol. 2017;176:99-109). “Even just after 6 months there’s an improvement in aerobic power,” he said.

And, he continued, other findings have suggested that treatment could lower mortality in men and reduce the number of deaths from malignant neoplasms in all patients (Eur J Endocrinol. 2017;176[1]:67-75).

However, Dr. Yuen cautioned that the confirmation of a survival benefit from hormone replacement will be speculative as long as there are no prospective data available.

He offered five tips about diagnosing and treating AGHD:

First, be aware that a number of conditions other than AGHD can cause low levels of insulin-like growth factor 1, including malnutrition, diabetes, untreated hypothyroidism, liver disease, and kidney failure.

Second, follow recommended algorithms for testing adult patients and transition those pediatric patients who seem to be at risk of having the condition. (Those moving from pediatric to adult care are known as transition patients.) The algorithms suggest that three diagnostic tests can be helpful, depending on the situation: the macimorelin test, the insulin tolerance test, and the glucagon stimulation test.

In 2017, the Food and Drug Administration approved the macimorelin (Macrilen) test, which requires the administration of an oral medication before a blood test. Dr. Yuen cited a phase 3 study that demonstrated that the test was “highly reproducible” and has a “good safety profile” (J Clin Endocrinol Metab. 2018;103[8]:3083-93). Dr. Yuen believes the test will become the preferred alternative to the insulin tolerance test.

Third, transition patients require special care as they move from pediatric care. “The handover is still very challenging,” Dr. Yuen said. “There’s still much to be done to improve the quality of treatment for these patients.” Challenges during the transition can include the patient’s reluctance to continue taking hormones in adulthood, he said. “Encourage pediatricians to start educating patients from early on that they’ll need to remain on hormones,” he advised, and help patients take accountability for their health in areas such as self-injection.

Patients may suffer from “injection fatigue,” they may be concerned about the side effects of the therapy, and/or they may be overwhelmed by the cost of care, he said. They may not understand how to manage their care and lack insight into the consequences of treatment cessation.

He advised endocrinologists to monitor transition patients who aren’t growth-hormone deficient because their status may change in the future.

Fourth, start treatment in adults with recommended doses of growth hormone. For those younger than 30 years, use 0.4-0.5 mg/day (higher for transition patients); for those aged between 30 and 60 years, use 0.2-0.3 mg/day; and for those who are older than 60 years, use 0.1-0.2 mg/day. Doses should be adjusted to 0.1-0.2 mg/day in patients with diabetes, obesity, and/or previous gestational diabetes.

Fifth, treat patients with growth hormone indefinitely if benefits are seen, but consider stopping treatment after a year if there doesn’t seem to be a benefit, Dr. Yuen advised. Follow up at 6 months, he recommended.

Dr. Yuen disclosed receiving research grants from and consulting for Pfizer, Novo Nordisk, and Aeterna Zentaris. He has also consulted for Strongbridge.

LOS ANGELES – More than 20 years ago, Roy Taylor, MD, began working to further understand the pathogenesis of hepatic insulin resistance in people with type 2 diabetes. It became clear that the main determinant was the amount of fat in the liver.

“If you reduced the amount of fat, the resistance went down,” Dr. Taylor, professor of medicine and metabolism at Newcastle University (England), said at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “We had a very clear picture of what might be controlling this awful matter of fasting glucose being too high.”

Then, Dr. Taylor read a study from Caterina Guidone, MD, and colleagues in Italy, which found that 1 week after patients with type 2 diabetes underwent gastric bypass surgery, their fasting plasma glucose levels became normal (Diabetes. 2006;55[7]:2025-31). “I was sitting at my desk and I thought, ‘This really changes type 2 diabetes,’ ” Dr. Taylor said. “It set in process a series of thoughts as to what was controlling what.”

This inspired ongoing work that Dr. Taylor termed the “twin-cycle hypothesis,” which postulates that chronic calorie excess leads to accumulation of liver fat, which spills over into the pancreas (Diabetologia. 2008;51[10]:1781-9).

“People with type 2 diabetes have been in positive calorie balance for a number of years,” he said. “That’s going to lead to an excess of fat in the body, and liver fat levels tend to rise with increasing body weight. If a person has normal insulin sensitivity in muscle tissue, then dealing with a meal is quite easy. Some 30 years ago, we showed using MR spectroscopy that you will have stored the carbohydrate from your breakfast in muscle, to the extent of about one-third of your breakfast, and the peak will be about 5 hours after breakfast. If you had your corn flakes at seven in the morning, by noon there will be peak in muscle, nicely stored away. However, if you happen to be insulin resistant in muscle, that doesn’t happen. There’s only one other pathway that the body can use, and that’s lipogenesis. The body can turn this very toxic substance [glucose] into safe storage [fat]. A lot of that happens in the liver. This means that people with insulin resistance tend to build up liver fat more rapidly than others.”

To test the twin-cycle hypothesis, Dr. Taylor and colleagues launched an 8-week study known as Counterpoint, which set out to induce negative calorie balance using a very low–calorie diet – about one-quarter of an average person’s daily food intake – in 11 people with diabetes (Diabetologia. 2011;54[10]:2506-14). The diet included consuming three packets of liquid formula food each day (46.4% carbohydrate, 32.5% protein, and 20.1% fat; plus vitamins, minerals, and trace elements), supplemented with portions of nonstarchy vegetables such that total energy intake was about 700 calories a day.

“On a liquid-formula diet, hunger is not a problem after the first 36 hours,” Dr. Taylor said. “This is one of the best-kept secrets of the obesity field. Our low-calorie diet was designed as something that people would be able to do in real life. We included nonstarchy vegetables to keep the bowels happy. That was important. It also fulfilled another point. People didn’t want just a liquid diet. They missed the sensation of chewing.”

The researchers also developed three-point Dixon MRI to measure pancreas and liver triacylglycerol content. “The pancreas was particularly challenging, and the full resources of the magnetic resonance physics team were needed to crack the technical problems,” he said.

After just 1 week of restricted energy intake, the fasting plasma glucose level normalized in the diabetic group, going from 9.2 to 5.9 mmol/L (P = .003), while insulin suppression of hepatic glucose output improved from 43% to 74 % (P = .003). By week 8, pancreatic triacylglycerol decreased from 8.0% to 1.1% (P = .03), and hepatic triacylglycerol content fell from 12.8% to 2.9% (P = .003).

“Within 7 days, there was a 30% drop in liver fat, and hepatic insulin resistance had disappeared,” Dr. Taylor said. “This is not a significant change – it’s a disappearance. For one individual, the amount of fat in the liver decreased from 36% to 2%. In fact, 2% [fat in the liver] was the average in the whole group. But what was simply amazing was the change in first-phase insulin response. It gradually increased throughout the 8 weeks of the study to become similar to the normal control group. We knew right away that a low-calorie diet would start correcting this central abnormality of type 2 diabetes.”

After the results from Counterpoint were published, Dr. Taylor received a “tsunami” of emails from researchers and from members of the public. “Some of the medical experts said it was a flash in the pan – interesting, but not relevant,” he said. “People with diabetes learned of it by the media, and it was talked about as a crash diet, which is unfortunate. First, it wasn’t a crash diet. This diet has to be very carefully planned, and people need to think about it in advance. They need to talk about it with their nearest and dearest, because it’s the spouse, the partner, the friends who will be supporting the individual through this journey. That’s critically important. People don’t eat as isolated individuals, they often eat as a family. We’re not talking about cure. We’re talking about reversal of the processes underpinning diabetes, with the aim of achieving remission.”

Dr. Taylor created a website devoted to providing information for clinicians and patients about the low-calorie diet and other tips on how to reverse type 2 diabetes. Soon afterward, he started to receive emails from people telling him about their experiences with the diet. “In the comfort of their own kitchens these people had lost the same amount of weight as in our trial subjects – about 33 pounds,” Dr. Taylor said. “Most of them had gotten rid of their type 2 diabetes. This was not something artificial as part of a research project. This was something that real people would do if the motivation was strong enough.”

To find out if the results from the Counterpoint study were sustainable, Dr. Taylor and his associates launched the Counterbalance study in 30 patients with type 2 diabetes who had a positive calorie imbalance and whom the researchers followed for 6 months. The 8-week diet consisted of consuming three packets of liquid formula a day comprising 43.0% carbohydrates, 34.0% protein, and 19.5% fat, as well as up to 240 g of nonstarchy vegetables (Diabetes Care. 2016;39[5]:808-15). “This was followed for a 6-month period of normal eating: Eating whatever foods they liked but in quantities to keep their weight steady,” Dr. Taylor explained. “These people gained no weight over the 6-month follow-up period. They achieved normalization of liver fat, and it remained normal.”

The patients’ hemoglobin A_1c levels fell from an average of 7.1% at baseline to less than 6.0%, and stayed at less than 6.0%. Patients who didn’t respond tended to have a longer duration of diabetes. Their beta cells had fallen to a level beyond that capable of recovery. “So the durability of the return to normal metabolic function was not in question, at least up to 6 months,” he said. “This study also gave us the opportunity to look at changes in pancreas fat. Was it likely that the liver fat was driving the pancreas fat? Yes.”

During the weight-loss period, the researchers found that there was the same degree of reduction of pancreas fat in the Counterbalance study as there’d been in the Counterpoint study. “Remarkably, it decreased slightly during the 6 months of follow-up,” Dr. Taylor said. “Those changes were significant. Type 2 diabetes seems to be caused by about a half a gram of fat within the cells of the pancreas.”

To investigate if a very low–calorie diet could be used as a routine treatment for type 2 diabetes, Dr. Taylor collaborated with his colleague, Mike Lean, MD, in launching the randomized controlled Diabetes Remission Clinical Trial (DiRECT) at 49 primary care practices in the United Kingdom (Diabetologia. 2018;61[3]:589-98). In all, 298 patients were randomized to either best-practice diabetes care alone (control arm) or with an additional evidence-based weight-management program (intervention arm). Remission was defined as having a hemoglobin A_1c level of less than 6.5% for at least 2 months without receiving glucose-lowering therapy.

At 1 year, 46% of patients in the intervention arm achieved remission, compared with 4% in the control arm (Lancet Diabetes Endocrinol. 2019;7[5]:344-55). At 2 years, 36% of patients in the intervention arm achieved remission, compared with 2% in the control arm. “The most common comment from study participants was, ‘I feel 10 years younger,’ ” Dr. Taylor said. “That’s important.”

The percentage of patients who achieved remission was 5% in those who lost less than 11 lb (5 kg), 29% in those who lost between 11 lb and 22 lb (5-10 kg), 60% in those who lost between 22 lb and 33 lb (10-15 kg), and 70% in those who lost 33 lb (15 kg) or more.

The researchers found that 62 patients achieved no remission at 12 or 24 months, 15 achieved remission at 12 but not at 24 months, and 48 achieved remission at 12 and 24 months. “We haven’t got this perfectly right yet,” Dr. Taylor said. “There is more work to do in understanding how to achieve prevention of weight gain, maybe with behavioral interventions and/or other agents such as [glucagonlike peptide–1] agonists. This is the start of a story, not the end of it.”

He and his associates also observed that delivery of fat from the liver to the rest of the body was increased in study participants who relapsed. “What effect did that have on the pancreas fat? The people who continued to be free of diabetes showed a slight fall in pancreatic fat between 5 and 24 months,” Dr. Taylor said. “In sharp contrast, the relapsers had a complete increase. Over the whole period of the study, the relapsers had not changed from baseline. It appears beyond reasonable doubt that excess pancreas fat seems to be driving the beta-cell problem underlying type 2 diabetes.”

Dr. Taylor reported that he has received lecture fees from Novartis, Lilly, and Janssen. He has also been an advisory board member for Wilmington Healthcare.

LOS ANGELES – Patients who took the sodium-glucose cotransporter-2 inhibitor canagliflozin after undergoing metabolic surgery experienced reductions in blood glucose, body mass index, and truncal body fat, results from a small pilot study have shown.

Doug Brunk/MDedge News

“We hypothesized that canagliflozin would be a good choice for these patients, because these drugs work independently of insulin,” the study’s principal investigator, Sangeeta R. Kashyap, MD, said in an interview at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “They help promote weight loss and improve blood pressure. [After] bariatric surgery, patients have an issue with weight regain, and sometimes their diabetes comes back.”

In what she said is the first prospective, randomized, controlled trial of its kind, Dr. Kashyap, an endocrinologist at the Cleveland Clinic, and her colleagues enrolled 11 women and 5 men with type 2 diabetes who had undergone Roux-en-Y gastric bypass or sleeve gastrectomy to study the effects of canagliflozin on clinical parameters over a period of 6 months. At baseline, the patients’ mean body mass index was 39.2 kg/m² and their mean hemoglobin A_1c level was 7.4%. The researchers used maximum likelihood estimation in a linear mixed-effect model to deduce differences between the treatment and placebo groups. Patients randomized to the study drug were assigned a 6-month course of canagliflozin, starting on 100 mg for 2 weeks titrated up to 300 mg daily.

At 6 months, fasting glucose was significantly reduced in the canagliflozin group, compared with baseline (from 163 to 122 mg/dL; P = .007), but it rose in the placebo group (from 164 to 192 mg/dL), a between-group difference that fell short of statistical significance (P = .12). In addition, C-reactive protein in the treatment group fell from 8.9 mg/L to 3.9 mg/L, but rose from 1.6 mg/L to 4.7 mg/L in the placebo group, a between-group difference that trended toward significance (P = .07).

During the 6-month study period, the mean BMI fell from 39.6 kg/m² to 38 kg/m² in the canagliflozin group but increased from 38 to 41 in the placebo group, a between-group difference that reached statistical significance (P = .014). Mean changes in body fat (a reduction of 1.82%), truncal fat (a reduction of 2.67%), and android fat (a reduction of 3%) also reached statistical significance in the treatment group, compared with the placebo group. Reductions in adiponectin, leptin, and high–molecular weight adiponectin did not reach statistical significance.

“I think these drugs have a place in post–bariatric surgery care,” Dr. Kashyap said. “Canagliflozin after metabolic surgery improved weight-loss outcomes and blood sugar levels. It also improved abdominal fat levels, and in this way might even lower cardiovascular disease risk in these patients.”

She acknowledged the study’s small sample size and single-center design as limitations. “It was very difficult to recruit patients for this study,” she said. “Not many patients have recurrent diabetes after bariatric surgery.”

Janssen provided funding to Dr. Kashyap for the trial.

LOS ANGELES – Patients who took the sodium-glucose cotransporter-2 inhibitor canagliflozin after undergoing metabolic surgery experienced reductions in blood glucose, body mass index, and truncal body fat, results from a small pilot study have shown.

“We hypothesized that canagliflozin would be a good choice for these patients, because these drugs work independently of insulin,” the study’s principal investigator, Sangeeta R. Kashyap, MD, said in an interview at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “They help promote weight loss and improve blood pressure. [After] bariatric surgery, patients have an issue with weight regain, and sometimes their diabetes comes back.”

In what she said is the first prospective, randomized, controlled trial of its kind, Dr. Kashyap, an endocrinologist at the Cleveland Clinic, and her colleagues enrolled 11 women and 5 men with type 2 diabetes who had undergone Roux-en-Y gastric bypass or sleeve gastrectomy to study the effects of canagliflozin on clinical parameters over a period of 6 months. At baseline, the patients’ mean body mass index was 39.2 kg/m² and their mean hemoglobin A_1c level was 7.4%. The researchers used maximum likelihood estimation in a linear mixed-effect model to deduce differences between the treatment and placebo groups. Patients randomized to the study drug were assigned a 6-month course of canagliflozin, starting on 100 mg for 2 weeks titrated up to 300 mg daily.

At 6 months, fasting glucose was significantly reduced in the canagliflozin group, compared with baseline (from 163 to 122 mg/dL; P = .007), but it rose in the placebo group (from 164 to 192 mg/dL), a between-group difference that fell short of statistical significance (P = .12).

LOS ANGELES – A phase 3 clinical trial shows promising results for an experimental drug called teprotumumab, which treats thyroid eye disease, researchers reported at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists.

“For the first time, there appears to be a medicine that can be given during the active phase of the disease and can actually reverse not just the eyelid swelling and the clinical activity score, but also reduce the eye bulging and double vision and [improve] the [patient’s] quality of life. It could be a watershed moment in the treatment of the disease,” said ophthalmologist Raymond Douglas, MD, PhD, professor of surgery at Cedar-Sinai Medical Center Los Angeles and the study’s coprincipal investigator, in an interview at the meeting.

According to Dr. Douglas, thyroid eye disease, which is also known as Graves’ eye disease, is a severely disabling condition that causes swelling, pain, discomfort, and blindness. “The burden really is quite significant,” he said, with an impact that’s been compared with that of breast cancer in quality-of-life studies.

“Current treatments for thyroid eye disease are rather limited,” he said. “They really encompass just reducing the swelling and the short-term manifestations of the disease. Treatments such as IV steroids and radiation have been shown to not have any effect on long-term manifestations such as eye bulging and double vision.”

Teprotumumab is a fully human monoclonal antibody that targets the insulinlike growth factor I receptor (IGF-IR). It seems to downregulate thyroid eye disease, Dr. Douglas said.

Researchers studied the drug in a randomized, placebo-controlled study: 41 patients were designated to receive eight intravenous infusions of the drug over 21 weeks (10 mg/kg for the first infusion, then 20 mg/kg thereafter). At week 24, 83% of the study group (34 of 41 patients) reached the endpoint of a reduction of eye bulging by at least 2 mm, compared with 10% of patients (4 of 42) in the placebo group, which received infusions of saline solution.

Two millimeters is significant, Dr. Douglas said. “If you noticed someone’s eye was bulging 2 millimeters, you’d say, ‘Hey, I think something is wrong with your eye.’ ”

Initial study results were released in February 2019. New data about secondary endpoints were released at the AACE meeting: Researchers reported that the average reduction in proptosis (eye bulging) was 2.82 mm in the study group, compared with 0.54 mm in the placebo group (P less than .001).

Dr. Douglas said he can “achieve 3 mm of reduction through surgery to drill out the bone between the eye and the brain. [The patients in the study group] were able to achieve almost 3 millimeters of reduction by the drug alone. It’s a rather significant improvement.”

The new data also provided some insight into the timing of clinical improvements. According to Dr. Douglas, “most of the endpoints were met as early as 6 weeks or [after] two infusions of this drug.”

The adverse effects were relatively mild and included muscle spasms, said Dr. Douglas. The side effects seem to be “well tolerated,” he noted, and none led to cessation of therapy.

Participants with potential for motherhood or fatherhood during the trial had to agree to take precautions to avoid becoming pregnant or impregnating a partner.

Dr. Douglas didn’t provide cost information about the drug. However, it seems likely to be expensive. A writer with Seeking Alpha, a stock market analysis site, estimated that the cost could reach “$250,000 or $300,000 per patient per year, which translates to a $3.7 billion to $6 billion market in the United States alone (based on the estimated patient population in the 15,000-20,000 range).”

The drug’s manufacturer, Horizon Therapeutics, expects to apply to the Food and Drug Administration later this year for approval of the drug.

If it is approved, endocrinologists will have an opportunity to partner with eye surgeons to treat thyroid eye disease, Dr. Douglas said. “The crux will be the comanagement with the endocrinologist helping to control the thyroid function and manage some of the side effects of this medication, and the oculoplastic surgeon [working on] diagnosis, appropriate use, and management.”

Horizon Therapeutics funded the study. Dr. Douglas disclosed that he is a consultant with the company.

LOS ANGELES – The dose of testosterone required to maintain a therapeutic level in transgender men is not correlated with body mass index but does decrease with age, results from a single-center study have shown.

“At this point, there are limited data regarding the dosing of testosterone in relation to age and BMI, which is what makes our work unique,” one of the study authors, Sushmitha Echt, MD, said in an interview following the annual scientific and clinical congress of the American Association of Clinical Endocrinologists.

“Although we have guidelines regarding initiating hormonal therapy for transgender patients, such as the Endocrine Society’s Clinical Practice Guidelines from 2017, we do not have much data regarding the optimal dosing of testosterone in transgender men. We hope that with more research, we will have more data to drive our treatment decisions for our transgender patients.”

Dr. Echt, an endocrinology fellow at North Shore University Hospital, Manhassett, NY, and her colleague, Aren Skolnick, DO, retrospectively evaluated 40 transgender men who were treated at the medical center between July 1, 2014 and July 1, 2018. They performed univariate and multivariate mixed-model analyses to determine the relationship between testosterone dose, age, and body mass index (BMI), and Cox regression analysis to determine the relationship between time to development of each physical attribute, testosterone dose, and route of administration.

The patients ranged in age from 18 to 54 years, and their mean baseline age was 25 years. At the time of their first visit, 32 of the patients were on intramuscular testosterone, four were on subcutaneous testosterone, and five were on the transdermal form.

By the end of the study, 28 patients remained on intramuscular testosterone, six were on the subcutaneous form, five were on the transdermal form, and one had transitioned to testosterone pellets. The majority of patients (37) became therapeutic during the course of the study, and the average therapeutic testosterone level was 551.7 ng/dL.

During an average follow-up time of one year, the researchers observed no correlation between testosterone dose and BMI. However, they found a negative correlation between testosterone dose and age, with or without adjustment for BMI (P = .016 and P = .020, respectively). Adjusted for BMI, the dose decreased by 2.0 mg for every one-year increase in age.

A subgroup analysis of the new patients again revealed a negative correlation between testosterone dose and age, with or without adjustment for BMI (P = .013 and P = .019, respectively). Adjusted for BMI, the dose decreased by 2.5 mg for every one-year increase in age.

Subgroup analysis of the patients already on testosterone therapy revealed no association between testosterone dose, age, and BMI. Among the new patients, no association was observed between time to development of each physical attribute and testosterone dose or route of administration. Among the new patients, 73% reported hair growth (mean time, 89 days), deepening of voice (51 days), and cessation of menses (136 days), and 59% reported clitoromegaly (51 days).

“The finding that surprised us the most is that the testosterone dose needed to maintain a therapeutic testosterone level in transgender men is not related to BMI,” Dr. Echt said. “Some medications are dosed based on body weight, and it was surprising to us that testosterone dosing was not related to weight in kilograms or BMI. Although the findings from our project suggest that the testosterone dose needed for hormonal therapy for transgender men may decrease with older age, further research and larger studies are needed in this field to help guide management of transgender patients.”

Dr. Echt acknowledged certain limitations of the study, including its small sample size. “At this point, our population of transgender patients has been increasing in our practice,” she said. “In the future, we would like to build upon our study by including more patients in our retrospective analysis and then stratify the results by mode of administration of testosterone.”

The researchers reported having no financial disclosures.

LOS ANGELES – There is no consistent evidence to suggest that subclinical hypothyroidism is linked to an increased risk of incident breast, prostate, or colon cancer. The condition, however, may be linked to an increased risk of thyroid malignancy and to an increased risk of overall cancer mortality.

These findings come from the first systematic review to examine the effect of subclinical hypothyroidism on the risk of incident cancer and cancer mortality.

“Subclinical hypothyroidism is very prevalent,” lead study author Oriana Yu, MD, MSc, said in an interview at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “It affects up to 10% of people, yet at this time we are uncertain as to whether or not [we should] treat them. Most studies have focused on cardiovascular outcomes, because we know that thyroid hormone is very important in lipid metabolism.”

Dr. Yu, an endocrinologist at McGill University, Montreal, and her colleagues searched the Ovid MEDLINE database for articles published from the date of its inception until Nov. 13, 2017, and combined words related to thyroid function and cancer in their search. They limited the analysis to randomized clinical trials and cohort and case-control studies in which the thyroid dysfunction chronologically preceded the cancer incidence or mortality by at least one year.

Of the 180 records screened, 51 full-text articles were assessed for eligibility. Of those, nine met the criteria for systematic review – seven related to cancer risk and two to cancer mortality. The studies were deemed to be of good to medium quality, but six of the nine were cohort studies, the rest case-control studies. “We had hoped to do a systematic review and meta-analysis, but there was high heterogeneity in the studies, especially in terms of different risk measures and outcomes reported,” Dr. Yu said. “As a result, we were not able to perform a meta-analysis.”

The researchers found that the studies had inconsistent findings when it came to the impact of subclinical hypothyroidism on the risk of breast, prostate, and colon cancer. For example, one prospective cohort study of 2,738 patients found no association between subclinical hypothyroidism and the risk of breast cancer (odds ratio, 1.9; 95% confidence interval, 0.8-4.9; Thyroid. 2005;15[11]:1253-9). Women with breast cancer, however, were more likely to have thyroid autoantibodies.

Meanwhile, a case-control study of 1,201 men found that those with elevated TSH levels had a decreased risk of prostate cancer (OR, 0.71; 95% CI, 0.47-1.06; PLoS One. 2012 Oct 30. doi: 10.1371/journal.pone.0047730). “That was a bit surprising to us,” Dr. Yu said. In addition, a nested case-control study of 103,044 patients found that subclinical hypothyroidism was linked to an increased risk for colon cancer (OR, 1.16; 95% CI, 1.08-1.24; J Natl Cancer Inst. 2015 Apr 8. doi: 10.1093/jnci/djv084).

Of the two studies that focused on cancer mortality, one retrospective cohort analysis of 4,735 patients showed that treatment of subclinical hypothyroidism was associated with a decreased risk of cancer mortality in those aged 40-70 years (hazard ratio, 0.59; 95% CI, 0.21-0.99; Arch Intern Med. 2012;172[10]:811-7). The other study, a retrospective cohort analysis of 115,746 patients, found that subclinical hypothyroidism was associated with an increased risk of cancer mortality (relative risk, 1.51; 95% CI, 1.06-2.15; PLoS One. 2015 Apr 1. doi: 10.1371/journal.pone.0122955).

“We need to interpret the cancer-related mortality findings with caution,” Dr. Yu said. “There’s concern about whether patients who are treated might be [generally] healthier or were less frail, compared with those who were not treated. Although these studies adjusted for a number of confounders, it may be difficult to measure and adjust for [those two] factors. That might explain the findings in the two studies on cancer-related mortality.”

LOS ANGELES – There is no consistent evidence to suggest that subclinical hypothyroidism is linked to an increased risk of incident breast, prostate, or colon cancer. The condition, however, may be linked to an increased risk of thyroid malignancy and to an increased risk of overall cancer mortality.

These findings come from the first systematic review to examine the effect of subclinical hypothyroidism on the risk of incident cancer and cancer mortality.

“Subclinical hypothyroidism is very prevalent,” lead study author Oriana Yu, MD, MSc, said in an interview at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “It affects up to 10% of people, yet at this time we are uncertain as to whether or not [we should] treat them. Most studies have focused on cardiovascular outcomes, because we know that thyroid hormone is very important in lipid metabolism.”

Dr. Yu, an endocrinologist at McGill University, Montreal, and her colleagues searched the Ovid MEDLINE database for articles published from the date of its inception until Nov. 13, 2017, and combined words related to thyroid function and cancer in their search. They limited the analysis to randomized clinical trials and cohort and case-control studies in which the thyroid dysfunction chronologically preceded the cancer incidence or mortality by at least one year.

Of the 180 records screened, 51 full-text articles were assessed for eligibility. Of those, nine met the criteria for systematic review – seven related to cancer risk and two to cancer mortality. The studies were deemed to be of good to medium quality, but six of the nine were cohort studies, the rest case-control studies. “We had hoped to do a systematic review and meta-analysis, but there was high heterogeneity in the studies, especially in terms of different risk measures and outcomes reported,” Dr. Yu said. “As a result, we were not able to perform a meta-analysis.”

LOS ANGELES – The 69-year-old woman with a history of type 2 diabetes had persistent hypoglycemia despite treatment with hydrocortisone, dextrose, and glucagon. Doctors in South Carolina worried about insulinoma and planned to launch an intra-arterial calcium stimulation test. But the medical team wasn’t quite certain it had the correct diagnosis.

Then along came a suspicious nurse who uncovered the truth: The patient had used syringes and vials of insulin socked away in a cosmetics bag. The diagnosis? An unusual, but not entirely rare, case of factitious hypoglycemia. That doesn’t mean her condition was fictional. Instead, it means she created it herself.

Randy Dotinga/MDedge News

• In any case of hypoglycemia, consider the possibility that the patient has factitious hypoglycemia. In every patient, he said, do a drug screen for sulfonylureas. “Now that we have multiple classes of diabetes drugs, most of which have a risk for hypoglycemia, one has to have a lab capable of measuring all of them. And that is not easy. It’s not just ‘draw the blood and send to your corner lab.’ ”
• Patients with factitious hypoglycemia don’t tend to have predictable dips in blood sugar during fasting or after meals. Instead, their symptoms are chaotic. “It all depends on when they’re taking [insulin],” he said.
• Patients with factitious hypoglycemia don’t seem ill, but those with insulinomas do. “Patients with insulinomas are totally incapable of living normal lives. They’re incapacitated. Their lives are so disrupted that some of them need ‘babysitters’,” Dr. Service said. If they “get the tumor removed, they are cured. Then they are back to the normal life.”
• Beware that patients may not realize they’re taking a medication that causes factitious hypoglycemia. It’s common, Dr. Service said, for a patient to accidentally take his or her spouse’s medication because of a mix-up.

Ultimately, the goal is to catch factitious hypoglycemia in time. Some physicians haven’t been so fortunate. “They only get to the right answer,” he said, “after the patient has recovered from surgery.”

LOS ANGELES – On the male fertility front, obesity seems to hurt semen quality. So does weight-loss surgery reverse the trend? A new review of existing research suggests that there may be an effect, but the findings aren’t conclusive.

“We found something,” said Sikarin Upala, MD, a second-year endocrinology fellow at the University of Chicago, who pointed out that three of the four reports he and his colleagues reviewed suggested improvement in semen motility. “But we still need to study more about whether bariatric surgery will affect infertility,” he continued.

Dr. Upala, who led the systematic review and meta-analysis of research into bariatric surgery and semen quality, spoke in an interview after his presentation at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists.

Researchers have linked obesity to infertility in men, but it’s not entirely clear how excess weight and sperm deficiencies are connected. As researchers explained in a 2018 report, “conflicting results have been observed in studies evaluating the correlation between [body mass index] and sperm parameters, such as sperm concentration and total sperm count.” However, they noted that it is “generally accepted” that men with obesity seem to be at higher risk of having a low sperm count or having azoospermia, which is the total lack of sperm in semen.

It’s also not clear whether weight loss directly improves male fertility. “We do know that androgen levels improve after weight-loss surgery, and that might be one factor among several that may contribute to improved male fertility,” Edward Lin, DO, MBA, FACS, professor of surgery and chief of gastrointestinal and general surgery at Emory University, Atlanta, said in an interview.

In their review, Dr. Upala and his colleagues analyzed four studies published between 2012 and 2018 that evaluated the effect of bariatric surgery on semen quality. All of the studies examined semen volume and sperm morphology and motility, and three examined sperm concentration.

A meta-analysis found that motility and volume improved after surgery; however, some of the studies (two for volume, one for motility) failed to show a statistically significant change.

There was no statistically significant difference in sperm morphology or concentration overall, although one study showed a statistically significant improvement in both categories.

Overall, “there might be a little bit of positive effect, but we couldn’t reach a good conclusion because there were too few studies,” Dr. Upala said.

Dr. Lin, director of the Emory Bariatrics Center, agreed that the review findings are limited. He said that although the findings hint at a positive effect on semen quality, “the jury is still out” when it comes to a link between bariatric surgery and male infertility.

“Multiple factors contribute to semen quality,” he added, pointing to vitamin deficiencies, micronutrient levels in the body, enzyme signaling pathways, and sperm chromatin integrity. “In fact, surgically or diet-induced weight loss may be associated with permissive malnutrition, which further exacerbates these deficiencies. Deficiencies in these areas can sometimes take months, if not years, to correct by taking vitamin D or copper or zinc, for example.”

Dr. Lin referred to a small study in which reporters observed semen abnormalities and subfertility after weight-loss surgery despite improvements in androgenic and quality of life levels.

Dr. Upala reported having no relevant disclosures.

LOS ANGELES – Cardiology patients can strap on a Holter monitor for a day or two to track their heart activity and get a brief but helpful glimpse at their cardiac health. Could patients with type 2 diabetes benefit by monitoring their blood sugar for a short period? Absolutely, according to an endocrinologist who says he’s had tremendous success with the temporary use of continuous glucose monitors (CGMs) in appropriate patients.

“There’s an actionable surprise with almost every patient,” said Daniel Einhorn, MD, FACP, FACE, medical director of Scripps Whittier Diabetes Institute and clinical professor of medicine at the University of California, San Diego.

The key is to use CGM data to pinpoint glucose spikes and then quickly make adjustments, typically over a period of 2 weeks. “This is about pattern recognition. We can do [CGM] over a week, see what the pattern is, and then try to fix something. Then they come back after the second week or send [the monitor] in, and they have the problem fixed. You have a happy patient and a happy family,” said Dr. Einhorn, who spoke in a presentation at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists.

He highlighted how CGM data allow patients to track their blood sugar over extended periods of time and detect patterns. The data can uncover hidden hypoglycemia and hyperglycemia, he said, and is much more useful to patients than the self-monitoring of glucose levels or hemoglobin A_1c (HbA_1c) data.

Reading the patterns, adjusting behavior

Dr. Einhorn discussed several specific cases of patients who had changed their behavior in regard to food or medicine after CGM data disclosed certain blood sugar patterns.

Often, he said, patients say they’re surprised to find their well-being improves after they make adjustments, saying something along the lines of “I didn’t feel badly, but I feel better now.” According to Dr. Einhorn, “You hear that all the time.”

For example, he said, one patient knew his blood sugar occasionally topped 200 mg/dL, but he felt all right and didn’t want to take insulin. CGM monitoring over 6 days showed the patient had continuous glucose levels well over 200 mg/dL, especially at night. The patient accepted insulin, and a few months later his HbA_1c dropped from 10.4% to 6.6%, and his blood sugar level stayed near or below the target range of 154 mg/dL.

Dr. Einhorn said the CGM data can reveal a range of problems, including:

• The “breakfast bump” after carbohydrate-heavy breakfasts of cereal, toast, and juice. “Breakfast cereal is diabolical,” he said.
• Hypoglycemia hours after exercise.
• Nocturnal hypoglycemia.
• Hypoglycemia unawareness.

Insurance coverage of the CGM device varies widely, he said, and insurers may not cover it at all in type 2 diabetes or only pay if the patient takes insulin. Fortunately, he said, the devices can be inexpensive.
 

Temporary use is not for everyone

Dr. Einhorn cautioned that temporary use of CGM is not appropriate for every patient with type 2 diabetes. “There’s absolutely a place for [permanent] monitoring for those people who have to make decisions throughout the day, especially if they are taking insulin,” he said.

And anyone with type 1 diabetes should use CGM on an ongoing basis, he emphasized. “Type 1 is a different world, a different universe,” he said.

He also noted that some patients don’t fare well on CGM, even on a temporary basis. That would include patients who hate to wear devices (possibly out of embarrassment), those who can’t manage to switch over from self-monitoring, and those who can’t manage to understand the data.

Dr. Einhorn disclosed various types of relationships with a number of drug makers, including Abbott, Boehringer Ingelheim, Novo, Sanofi, Janssen, and others.

Dr. Einhorn cautioned that temporary use of CGM is not appropriate for every patient with type 2 diabetes. “There’s absolutely a place for [permanent] monitoring for those people who have to make decisions throughout the day, especially if they are taking insulin,” he said.

And anyone with type 1 diabetes should use CGM on an ongoing basis, he emphasized. “Type 1 is a different world, a different universe,” he said.

He also noted that some patients don’t fare well on CGM, even on a temporary basis. That would include patients who hate to wear devices (possibly out of embarrassment), those who can’t manage to switch over from self-monitoring, and those who can’t manage to understand the data.

Dr. Einhorn disclosed various types of relationships with a number of drug makers, including Abbott, Boehringer Ingelheim, Novo, Sanofi, Janssen, and others.

LOS ANGELES – Cardiology patients can strap on a Holter monitor for a day or two to track their heart activity and get a brief but helpful glimpse at their cardiac health. Could patients with type 2 diabetes benefit by monitoring their blood sugar for a short period? Absolutely, according to an endocrinologist who says he’s had tremendous success with the temporary use of continuous glucose monitors (CGMs) in appropriate patients.

“There’s an actionable surprise with almost every patient,” said Daniel Einhorn, MD, FACP, FACE, medical director of Scripps Whittier Diabetes Institute and clinical professor of medicine at the University of California, San Diego.

The key is to use CGM data to pinpoint glucose spikes and then quickly make adjustments, typically over a period of 2 weeks. “This is about pattern recognition. We can do [CGM] over a week, see what the pattern is, and then try to fix something. Then they come back after the second week or send [the monitor] in, and they have the problem fixed. You have a happy patient and a happy family,” said Dr. Einhorn, who spoke in a presentation at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists.

He highlighted how CGM data allow patients to track their blood sugar over extended periods of time and detect patterns. The data can uncover hidden hypoglycemia and hyperglycemia, he said, and is much more useful to patients than the self-monitoring of glucose levels or hemoglobin A_1c (HbA_1c) data.

Reading the patterns, adjusting behavior

Dr. Einhorn discussed several specific cases of patients who had changed their behavior in regard to food or medicine after CGM data disclosed certain blood sugar patterns.

Often, he said, patients say they’re surprised to find their well-being improves after they make adjustments, saying something along the lines of “I didn’t feel badly, but I feel better now.” According to Dr. Einhorn, “You hear that all the time.”

For example, he said, one patient knew his blood sugar occasionally topped 200 mg/dL, but he felt all right and didn’t want to take insulin. CGM monitoring over 6 days showed the patient had continuous glucose levels well over 200 mg/dL, especially at night. The patient accepted insulin, and a few months later his HbA_1c dropped from 10.4% to 6.6%, and his blood sugar level stayed near or below the target range of 154 mg/dL.

Dr. Einhorn said the CGM data can reveal a range of problems, including:

• The “breakfast bump” after carbohydrate-heavy breakfasts of cereal, toast, and juice. “Breakfast cereal is diabolical,” he said.
• Hypoglycemia hours after exercise.
• Nocturnal hypoglycemia.
• Hypoglycemia unawareness.

Insurance coverage of the CGM device varies widely, he said, and insurers may not cover it at all in type 2 diabetes or only pay if the patient takes insulin. Fortunately, he said, the devices can be inexpensive.
