TBD Meeting (5087-20)

LAS VEGAS – More than 10 years ago, Gerard Sanacora, PhD, MD, came across a study in the medical literature that stopped him in his tracks.

For the study, Austrian neurologist Eberhard A. Deisenhammer, MD, and colleagues sought to determine the length of the period between consideration and accomplishment of a suicide attempt (J Clin Psychiatry. 2009;70[1]:19-24). To do so, they interviewed 82 patients who were referred to a psychiatric university hospital after a suicide attempt. Nearly half of the patients (48%) reported that the period between the first current thought of suicide and the actual attempt had lasted 10 minutes or less.

“When you’re talking about treating suicide behavior, there are so many components: the impulsivity component, the resilience component – all these things that can’t be measured with a simple outcome measure,” Dr. Sanacora said at an annual psychopharmacology update held by the Nevada Psychiatric Association. “That’s one of the real challenges. It requires us to take a good look at how we’re treating these patients in general.”

It also underscores the need for new treatments that target suicidal ideation and behavior.

“There is increasing evidence that ketamine and esketamine can produce effects that could be used in the treatment of mood disorder patients with suicidal ideation or behavior,” said Dr. Sanacora, professor of psychiatry at Yale University, New Haven, Conn. “However, there are many challenges to performing the studies that are required to more definitively demonstrate rapid and sustained improvement in suicide risks.”

The global 12-month prevalence of nonfatal suicide attempts is about 0.3% to 0.4%, and the lifetime prevalence is 3%, “which is pretty shocking,” he said. In the United States, there are more than 30 suicide attempts for each suicide death. At the same time, a World Health Organization community survey conducted in 21 countries found that the 12-month prevalence of suicidal ideation was about 2%, and that the lifetime prevalence was 9%. “These are large numbers that we’re talking about internationally,” said Dr. Sanacora, who also directs the Yale Depression Research Program. In 2013, suicidal ideation constituted nearly 1% of all adult ED visits in the United States, with conservative costs of $2.2 billion. “Every step along the process takes a large toll on the health care system and society, from the top level of completed suicide to suicidal ideation,” he said.

According to 2016 data from the Centers for Disease Control and Prevention, nearly 10 million people in the United States have seriously considered suicide, about 2.5 million made a plan, about 1 million attempted suicide, and about 40,000 completed suicide. “We have to think about what we’re treating,” Dr. Sanacora said. “Are we treating the suicidal ideation, or are we trying to prevent completed suicides?”

A prior history of attempted suicide is the strongest single predictive factor of a completed suicide. “In fact, the risk of dying by suicide is approximately 100 times than that of the general population within 1 year of an index attempt,” he said. Another major risk factor is having a previous psychiatric hospitalization. In fact, up to 41% of those who completed suicide had been psychiatric inpatients within the previous year, and as many as 9% of suicides occurred within 1 day of discharge from psychiatric inpatient care. Other identified risk factors include marital status, belonging to a sexual minority, occupation, military service, general medical comorbidities, diagnosis of personality disorder, chronic pain, traumatic brain injury, childhood abuse, location of residence, access to firearms, and family history of suicide. Protective factors include having a strong social support network, being a parent, and religiosity. “These are things that typically aren’t part of a treatment, but they can be woven into a treatment plan in some way,” he said.

Other identified risk symptoms include feelings of worthlessness and hopelessness, the combination of depression and anxiety, and psychosis, regardless of the specific diagnosis.

Medical stabilization constitutes the first step in the standard treatment approach to suicidal ideation and behavior. “You want to make sure the person is hospitalized and take care of any injuries that may have been sustained in the suicide attempt,” Dr. Sanacora said. The next step is reducing the immediate risks. “For the most part, that’s making sure the individual is in a safe setting commensurate with the level of risk,” he said. “You want to remove any other risks that could be around them. Then, you want to assure that an appropriate level of follow-up is provided on stepdown to lower levels of care. That year after hospitalization puts you at incredible risk, so we want to make sure we’re not just treating something in the acute phase and then not having longer-term follow-up for it.”

Existing treatments that have some evidence to help with the treatment of suicidal ideation and behavior include the use of antidepressants, lithium, and clozapine, but these agents are far from fast-acting for a patient in crisis. “In addition, a lot of docs are hesitant to give lithium because it has the potential of overdose itself,” Dr. Sanacora said. With clozapine, he continued, “there is some level of confounding by indication because, when you’re giving clozapine, it’s usually a more reliable patient, one who is not at risk of self-harm.”

The STAR*D (Sequenced Treatment Alternatives to Relieve Depression) trial demonstrated that, for the patients who do not respond to the first two levels of treatment with citalopram, their chances of having a remission by getting a third or fourth level of treatment is reduced to below 15% (Am J Psychiatry. 2006;163[1]:28-40).

“This suggests that, with our current armamentarium, we are limited,” said Dr. Sanacora, who is also codirector of the Yale New Haven Hospital Interventional Psychiatry Service. In the STAR*D trial, the time to response to citalopram was 6 weeks in 50% of patients. “So, when somebody is going through a crisis and is at imminent risk for suicide, and you tell them, ‘You’ll be 50% better in 6 weeks,’ that’s hard to swallow,” he said.

Recent studies of ketamine and esketamine have demonstrated a rapid onset of effect in patients with major depressive disorder, but whether they alter suicidal ideation and behavior remains unclear. “If you are wanting to improve suicidal ideation and behavior, what outcome measure are you using to do this?” Dr. Sanacora asked. “It may seem simple, but it’s not. To do a clinical trial, you would need large sample sizes to look at behavior as an outcome. In fact, even retrospective studies on this topic don’t have enough events to give you statistical meaning.” This leaves clinicians to consider scales that have been used for examining suicidal ideation and behavior over the years, including the MINI suicidality module, the SAD PERSONS scale, and the Suicide Intent Scale. “However, while they could have some value to be used clinically, these scales really don’t have great value as outcome measures,” Dr. Sanacora said.

There also have been attempts to develop scales that capture changes in suicidal ideation and behavior over time, including the C-SSRS (Columbia-Suicide Severity Rating Scale) and the Sheehan Suicidality Tracking Scale. “The sad thing is, none of these measures have been proven to be very useful clinically,” he said. “They may have some level of sensitivity and specificity, but their actual predictive value is not great. So using these clinically is somewhat difficult.”

In 2018, Dr. Sanacora and his colleagues published results from a systematic review and individual participant data meta-analysis examining the effects of a single dose of ketamine on suicidal ideation (Am J Psychiatry. 2018;175[2]:150-8). The analysis included 167 participants with suicidal ideation at baseline. “Within 24 hours there was a very clear decrease in suicidal ideation in terms of clinician-reported scale,” he said. “Over 50% of patients reported having minimal or no ideation after treatment. That was maintained for 7 days.” Effect sizes were moderate to large at all time points post dose.

In the largest meta-analysis of its kind to date, researchers reviewed 15 independent trials of ketamine for suicide ideation in 572 adults with psychiatric disorders, all with a single dose of drug with varying routes and dosages (Aust N Z J Psychiatry. 2020;54[1]:29-45). The researchers in that study concluded that ketamine “may have a role in acute treatment for suicidality. However, there is clearly a need for clinical measures to ensure persistence of any benefits.”

Esketamine, which was approved in March 2019 for major depressive disorder, also shows promise in patients with suicidal ideation and behavior. In a double-blind, multicenter, proof-of-concept study, researchers randomized 68 participants to receive esketamine (84 mg) or placebo twice weekly for 4 weeks, in addition to comprehensive standard-of-care treatment (Am J Psychiatry. 2018;175[7]:620-30). The primary efficacy endpoint was change in score from baseline to 4 hours after initial dose on the MADRS (Montgomery-Asberg Depression Rating Scale). “There was a nice effect in the antidepressant response, compared with placebo. It hit the primary endpoint at 4 hours. The patients got treated twice a week for 4 weeks. People got better quickly and stayed well moving on.” The researchers also found that the rate of remission at day 25 was 60% in the esketamine group, compared with 42% in the placebo group. “The take-home message is that, even without the esketamine, the remission rate was 42% at day 25. That means if you’re giving people really good care, meaning that you’re seeing them twice a week and they’re inpatient until they’re able to go outpatient, people can do pretty well with that level of care.”

Meanwhile, additional evidence supporting the use of ketamine in acute care settings is starting to emerge. In a proof-of-concept trial, 18 depressed subjects with acute suicidal ideation who presented to the emergency department and required hospitalization were randomized to either IV ketamine 0.2 mg/kg or to saline placebo (Depress Anxiety. 2019 Nov 16. doi: 10.1002/da.22975). Ninety minutes after infusion, 88% of patients in the ketamine group had achieved remission of suicidal ideation, compared with 33% in the placebo group (P less than .05). No serious adverse events were noted.

“There is a clear need for new treatments targeting suicidal ideation and behavior,” Dr. Sanacora concluded. “Any plan to institute a rapid-acting treatment for individuals with imminent risk of suicidal behavior must be placed in the context of a larger comprehensive treatment plan. Getting somebody to feel better in the short run is great, but you really have to think about the whole treatment plan.”

Dr. Sanacora reported having received grants and research support from numerous pharmaceutical companies. He also holds an ownership interest in Biohaven Pharmaceuticals.

LAS VEGAS – Repetitive transcranial magnetic stimulation methods for treatment-resistant depression continue to be refined.

“Original studies have relatively low response rates, but we’re seeing better response rates as we figure out the localization, the parameters, the wave form, and how frequently you can give it,” Alan F. Schatzberg, MD, said at an annual psychopharmacology update held by the Nevada Psychiatric Association.

Repetitive transcranial magnetic stimulation (rTMS) involves the application of a magnetic field to a particular area of the brain, typically the dorsal lateral aspect of the prefrontal cortex. “It’s a weaker stimulant than electroconvulsive therapy, but it’s more focused and a lot safer,” said Dr. Schatzberg, professor of psychiatry and behavioral sciences at Stanford (Calif.) University. “It does not require anesthesia. In fact, it does seem to have some antidepressant effects.”

The original trial that applied this technology was conducted in 301 medication-free patients with major depression who had not benefited from prior treatment (Biol Psychiatry. 2007;62[11]:1208-16). Of the 301 patients, 155 received active rTMS, while 146 received sham rTMS. Treatment sessions were conducted five times per week for 4-6 weeks. The primary outcome was the symptom score change as assessed at week 4 with the Montgomery-Åsberg Depression Rating Scale (MADRS). Secondary outcomes included changes on the 17- and 24-item Hamilton Depression Rating Scale (HAMD), and response and remission rates with the MADRS and HAMD.

Response rates were significantly higher with active TMS on all three scales at weeks 4 and 6. Remission rates were approximately twofold higher with active TMS at week 6 and significant on the MADRS and HAMD24 scales (but not the HAMD17 scale). “The response rate for patients receiving active treatment was about 20%, and the remission at 6 weeks was about 18%,” said Dr. Schatzberg, who was an adviser to the study. “It was about twofold higher than in the sham group. It’s not dramatically effective, but it certainly is better than the sham control.” The MADRS score dropped about 6 points in the rTMS group, compared with about 2 points in the sham group, while the HAMD 24 score dropped about 7 points in the rTMS group, compared with about 3.5 points in the sham group.

In a separate, multisite, sham-controlled trial supported by the National Institutes of Health, researchers enrolled 199 antidepressant drug-free patients to determine whether daily left prefrontal rTMS safely and effectively treats major depressive disorder (Arch Gen Psychiatry. 2010;67[5]:507-16). Over the course of 3 weeks, the researchers delivered rTMS to the left prefrontal cortex for 37.5 minutes (3,000 pulses per session) using a figure-eight solid-core coil. Sham rTMS used a similar coil with a metal insert blocking the magnetic field and scalp electrodes that delivered matched somatosensory sensations. The retention rate was 88%, and no device-related serious adverse events were reported. A significantly greater proportion of patients treated with rTMS achieved remission, compared with those in the sham group (15% vs. 5%, respectively; P = .02). The odds of attaining remission were 4.2 times greater with active rTMS than with the sham treatment.

“These are not huge remission and response rates,” Dr. Schatzberg said of the results from this and other studies. “What can we do to start increasing efficacy? One thing you can do is design a better coil. You can alter the site of application, and you can change the pulse frequency and the pulse number. You can also change the brain wave focus. Theta seems to be mostly associated with hippocampal function around memory. Because of that, a number of groups starting giving theta waves.”

In one such study, researchers used accelerated, high-dose intermittent theta burst stimulation (iTBS) to treat highly treatment-resistant depression patients (Brain. 2018;141[3]:e18). The treatment lasted 5 days and consisted of 10 sessions per day, with 50 minutes between each session. “It’s a much more intensive system that delivers about 90,000 pulses,” said Dr. Schatzberg, who directs the Stanford Mood Disorders Center. Most patients remitted, but the durability of therapeutic response was weak, and all patients relapsed within 2 weeks post treatment.

“There’s more work to be done, but rTMS is really a good technology,” he concluded. “I think we will achieve much higher rates of success with this treatment once we push the envelope a little bit.”

Dr. Schatzberg disclosed that he has served a consultant to Alkermes, Avanir, Bracket, Compass, Delpor, Epiodyne, Janssen, Jazz, Lundbeck, McKinsey, Merck, Myriad Genetics, Owl, Neuronetics, Pfizer, Sage, and Sunovion.

LAS VEGAS – Repetitive transcranial magnetic stimulation methods for treatment-resistant depression continue to be refined.

“Original studies have relatively low response rates, but we’re seeing better response rates as we figure out the localization, the parameters, the wave form, and how frequently you can give it,” Alan F. Schatzberg, MD, said at an annual psychopharmacology update held by the Nevada Psychiatric Association.

Repetitive transcranial magnetic stimulation (rTMS) involves the application of a magnetic field to a particular area of the brain, typically the dorsal lateral aspect of the prefrontal cortex. “It’s a weaker stimulant than electroconvulsive therapy, but it’s more focused and a lot safer,” said Dr. Schatzberg, professor of psychiatry and behavioral sciences at Stanford (Calif.) University. “It does not require anesthesia. In fact, it does seem to have some antidepressant effects.”

The original trial that applied this technology was conducted in 301 medication-free patients with major depression who had not benefited from prior treatment (Biol Psychiatry. 2007;62[11]:1208-16). Of the 301 patients, 155 received active rTMS, while 146 received sham rTMS. Treatment sessions were conducted five times per week for 4-6 weeks. The primary outcome was the symptom score change as assessed at week 4 with the Montgomery-Åsberg Depression Rating Scale (MADRS). Secondary outcomes included changes on the 17- and 24-item Hamilton Depression Rating Scale (HAMD), and response and remission rates with the MADRS and HAMD.

Response rates were significantly higher with active TMS on all three scales at weeks 4 and 6. Remission rates were approximately twofold higher with active TMS at week 6 and significant on the MADRS and HAMD24 scales (but not the HAMD17 scale). “The response rate for patients receiving active treatment was about 20%, and the remission at 6 weeks was about 18%,” said Dr. Schatzberg, who was an adviser to the study. “It was about twofold higher than in the sham group.

LAS VEGAS – Between 2010 and 2017, the proportion of newly diagnosed cases of acute hepatitis C virus infection rose threefold, driven largely by the concomitant opioid epidemic.

Doug Brunk/MDedge News

That makes efforts to screen, diagnose, and cure high-risk populations more important than ever, Stevan A. Gonzalez, MD, said at an annual psychopharmacology update held by the Nevada Psychiatric Association.

About 70% of HCV cases are related to injection drug use,” said Dr. Gonzalez, medical director of liver transplantation at the Baylor Simmons Transplant Institute at the Baylor Scott & White All Saints Medical Center in Fort Worth, Tex. “This is affecting whites as much as blacks and Hispanics, females as much as males, and in nonurban areas as much as in urban areas.”

Data from the Centers for Disease Control and Prevention and the Substance Abuse and Mental Health Services Administration indicate that during 2004-2014, the number of acute HCV cases among those aged 18-29 years increased 400%, and the use of injection opioids rose 600%.

At the same time, the number of HCV cases among those aged 30-39 years increased 325%, and the use of injection opioids rose 83%.

“We’re starting to see a pattern overlapping between HCV exposure and opioid injection,” Dr. Gonzalez said. Other high-risk populations include homeless and incarcerated individuals.

More than 70 million people worldwide have chronic HCV infection, Dr. Gonzalez noted, with possibly as many as 5 million cases in the United States. It remains the nation’s most common blood-borne infection.

Chronic disease develops in up to 85% of people who are exposed, infection is asymptomatic, and HCV remains one of the leading indications for liver transplantation and causes of liver cancer.

From a geographic standpoint, the prevalence of HCV in young adults is eclipsing that of Baby Boomers in several states in the Appalachian region and in Northeast, which have long been trouble spots for opioid use disorder (Gastroenterol. 2018 May;154[6]:1850-1).

Surprising exposure risk

The primary risk of transmission is through contaminated blood and the exposure through needles.

“It really doesn’t matter whether it’s a needle that has a small amount of dead space where a little bit of blood can remain or needles that have a larger amount of blood,” Dr. Gonzalez said.

“I’ve had patients who come to me and say, ‘I can’t believe I have HCV. It’s impossible. I always use my own needles. They’re always brand new; I’ve never shared with anybody,’” he continued.

“This is where education and awareness is so critical, because it’s not just the needles,” Dr. Gonzalez explained. “HCV can survive on inanimate objects. For example, on a tabletop surface or a water container, HCV can remain viable up to 3 weeks. In a syringe, 2 months. For that reason, HCV can also be transmitted through crack pipes and nasal drug use, where the prevalence can be up to 35%.”

The duration of a person’s HCV infection drives the transmission.

“That’s important to think about, because people who have chronic hepatitis C are infectious until they’re treated,” Dr. Gonzalez said. “If they don’t know that they have hepatitis C, they continue to transmit the virus to others.”

One study found that half of people living with HCV are unaware of their infection (PLoS One. 2014 Jul 2;9[7]:e101554). According to Dr. Gonzalez, forthcoming guidelines from the U.S. Preventive Services Task Force are expected to recommend a one-time screening for HCV infection in all adults aged 18-79 years, a Grade B recommendation. “That’s a big deal,” he said. (The draft recommendations are available here.)

HCV infection disproportionately affects individuals in correctional institutions. In fact, an estimated one in three inmates in the United States has chronic HCV.

“This is sort of a forgotten population with a lot of substance use and mental illness,” Dr. Gonzalez said. “Injection drug use in that setting is the most common risk factor: It’s about 60% in terms of the risk of transmission within correctional settings. HCV-associated liver disease has now surpassed HIV as a cause of death within correctional settings.”
 

Weighing treatment options

The most common oral regimens for chronic HCV include sofosbuvir/ledipasvir, sofosbuvir/velpatasvir, and glecaprevir/pibrentasvir. They achieve cure in 93%-100% of cases.

“HCV can be cured; it can be eradicated from the body long term,” Dr. Gonzalez said. “The choice of regimen, treatment duration, and use of ribavirin depends on the presence/absence of cirrhosis, prior treatment experience, and the genotype.”

All six forms of the HCV genotype can be treated with oral medication, he added, and methadone, bupropion, and naloxone are safe to use during therapy.

Reinfection following HCV treatment occurs infrequently. Dr. Gonzalez cited a randomized, controlled trial presented as an abstract at the 2018 annual meeting of the American Association for the Study of Liver Diseases. That study’s researchers found that – among 199 patients on opioid-replacement therapy who were receiving direct-acting antiviral therapy, in whom greater than 50% were actively using drugs – the rate of reinfection at 3 years was 1.8 reinfections/100 person-years.

“That’s lower than people expect,” Dr. Gonzalez said.
 

How to boost screening

Electronic health record systems can be used as an important tool to increase HCV screening in health care settings.

In 2017, researchers published an analysis of three randomized trials carried out at three separate primary care settings to improve screening for HCV: repeated mailings, an EHR best practice alert (BPA), and patient solicitation (Hepatology 2017 Jan;65[1]:44-53). They evaluated HCV antibody testing, diagnosis, and costs for each of the interventions, compared with standard-of-care testing.

The investigators found that the BPA intervention had the lowest incremental cost per completed test – $24 with fixed start-up costs, including technical design and development of the BPA system; $3 without fixed start-up costs. The BPA intervention also had the lowest incremental cost per new case identified.

Other efforts to expand access to screening and treatment are underway.

In 2019, Louisiana health officials negotiated a one-time fee for unlimited access for 5 years to sofosbuvir/velpatasvir (Epclusa) to treat the estimated 30,000 patients on Louisiana Medicaid and in that state’s department of corrections who have HCV.

“The goal is 90% cure; the burden is on the state health department to screen, diagnose, and dispense medication,” Dr. Gonzalez said.

Also in 2019, the state of Washington used an open bidding process to negotiate access to glecaprevir/pibrentasvir (Mavyret) for the state’s Medicaid population who have HCV.

“Those states are setting the pace,” Dr. Gonzalez said. “They are showing examples of how we can start implementing a process to treat these vulnerable populations.”

Meanwhile, the World Health Organization set a goal of eliminating viral hepatitis as a major public health threat by 2030.

“That sounds ambitious, but I think it’s possible,” Dr. Gonzalez said. “It’s important to address these high-risk populations: the incarcerated, people who use drugs, and the homeless, because those are the groups that have a high prevalence of HCV – mainly through injection drug use.

“If we don’t address that population, and we only target the general population, we’re going to have a continual source of transmission,” Dr. Gonzalez warned. “In that case, we would never be able to achieve elimination.”

Dr. Gonzalez disclosed that he is a member of the speakers bureau for AbbVie and Salix.

“That’s lower than people expect,” Dr. Gonzalez said.
 

How to boost screening

Electronic health record systems can be used as an important tool to increase HCV screening in health care settings.

In 2017, researchers published an analysis of three randomized trials carried out at three separate primary care settings to improve screening for HCV: repeated mailings, an EHR best practice alert (BPA), and patient solicitation (Hepatology 2017 Jan;65[1]:44-53). They evaluated HCV antibody testing, diagnosis, and costs for each of the interventions, compared with standard-of-care testing.

The investigators found that the BPA intervention had the lowest incremental cost per completed test – $24 with fixed start-up costs, including technical design and development of the BPA system; $3 without fixed start-up costs. The BPA intervention also had the lowest incremental cost per new case identified.

Other efforts to expand access to screening and treatment are underway.

In 2019, Louisiana health officials negotiated a one-time fee for unlimited access for 5 years to sofosbuvir/velpatasvir (Epclusa) to treat the estimated 30,000 patients on Louisiana Medicaid and in that state’s department of corrections who have HCV.

“The goal is 90% cure; the burden is on the state health department to screen, diagnose, and dispense medication,” Dr. Gonzalez said.

Also in 2019, the state of Washington used an open bidding process to negotiate access to glecaprevir/pibrentasvir (Mavyret) for the state’s Medicaid population who have HCV.

“Those states are setting the pace,” Dr. Gonzalez said. “They are showing examples of how we can start implementing a process to treat these vulnerable populations.”

Meanwhile, the World Health Organization set a goal of eliminating viral hepatitis as a major public health threat by 2030.

“That sounds ambitious, but I think it’s possible,” Dr. Gonzalez said. “It’s important to address these high-risk populations: the incarcerated, people who use drugs, and the homeless, because those are the groups that have a high prevalence of HCV – mainly through injection drug use.

“If we don’t address that population, and we only target the general population, we’re going to have a continual source of transmission,” Dr. Gonzalez warned. “In that case, we would never be able to achieve elimination.”

Dr. Gonzalez disclosed that he is a member of the speakers bureau for AbbVie and Salix.

LAS VEGAS – Clinicians should spend 1 hour with patients who present with a chief complaint of insomnia, rather than rushing to a treatment after a 10- to 15-minute office visit, according to John W. Winkelman, MD, PhD.

Doug Brunk/MDedge News

“Why? Because sleep problems are usually multifactorial, involving psychiatric illness, sleep disorders, medical illness, medication, and poor sleep hygiene/stress,” he said at an annual psychopharmacology update held by the Nevada Psychiatric Association. “There are usually many contributing problems, and sleep quality is only as strong as the weakest link. Maybe you don’t have an hour [to meet with new patients], but you need to give adequate time, otherwise you’re not going to do justice to the problem.”

During that first visit, Dr. Winkelman recommends establishing and prioritizing goals with the patient. “Ask, ‘what is it that bothers you most about your insomnia? Is it the time awake at night, your total sleep time, or how you feel during the day?’ Because we’re going to use different approaches based on that chief complaint of the insomnia,” said Dr. Winkelman, chief of the Massachusetts General Sleep Disorders Clinical Research Program in the department of psychiatry at Harvard Medical School, Boston. “Cognitive-behavioral therapy for insomnia [CBT-I], for instance, is very good at reducing time awake at night. It won’t increase total sleep time, but it reduces time awake at night dramatically.”

According to the DSM-5, insomnia disorder is marked by dissatisfaction with sleep quality or quantity associated with at least one of the following: difficulty initiating sleep, difficulty maintaining sleep, and early morning awakening. “Just getting up to pee five times a night is not insomnia,” he said. “Just taking an hour and a half to fall asleep at the beginning of the night is not insomnia. There has to be distress or dysfunction related to the sleep disturbance, for a minimum of three times per week for 3 months.”

Most sleep problems are transient, but 25%-30% last more than 1 year. The differential diagnosis for chronic insomnia includes primary psychiatric disorders, medications, substances, restless legs syndrome, sleep schedule disorders, and obstructive sleep apnea.

“In general, we do not order sleep studies in people with insomnia unless we suspect sleep apnea; it’s just a waste of time,” said Dr. Winkelman, who is also a professor of psychiatry at Harvard Medical School. Indications for polysomnography include loud snoring plus one of the following: daytime sleepiness, witnessed apneas, or refractory hypertension. Other indications include abnormal behaviors or movements during sleep, unexplained excessive daytime sleepiness, and refractory sleep complaints, especially repetitive brief awakenings.

Many common cognitive and behavioral issues can produce or worsen insomnia, including inconsistent bedtimes and wake times. “That irregular schedule wreaks havoc with sleep,” he said. “It messes up the circadian rhythm. Also, homeostatic drive needs to build up: We need to be awake 16 or more hours in order to be sleepy. If people are sleeping until noon on Sundays and then trying to go to bed at their usual time, 10 or 11 at night, they’ve only been awake 10 or 11 hours. That’s why they’re going to have problems falling asleep. Also, a lot of people doze off after dinner in front of the TV. That doesn’t help.”

Spending excessive time in bed can also trigger or worsen insomnia. Dr. Winkelman recommends that people restrict their access to bed to the number of hours it is reasonable to sleep. “I see a lot of people in their 70s and 80s spending 10 hours in bed,” he said. “It doesn’t sound that crazy, but there is no way they’re going to get 10 hours of sleep. It’s physically impossible, so they spend 2 or 3 hours awake at night.” Clock-watching is another no-no. “In the middle of the night you wake up, look at the clock, and say to yourself: ‘Oh my god, I’ve been awake for 3 hours. I have 4 hours left. I need 7 hours. That means I need to go to sleep now!’ ”

An estimated 30%-40% of people with chronic insomnia have a psychiatric disorder. That means “you have to be thorough in your evaluation and act as if you’re doing a structured interview,” Dr. Winkelman said. “Ask about obsessive-compulsive disorder, generalized anxiety disorder, PTSD, et cetera, so that you understand the complete myriad of psychiatric illnesses, because psychiatric illnesses run in gangs. Comorbidity is generally the rule.”

The first-line treatment for chronic insomnia disorder is CBT-I, a multicomponent approach that includes time-in-bed restriction, stimulus control, cognitive therapy, relaxation therapy, and sleep hygiene. According to Dr. Winkelman, the cornerstone of CBT-I is time-in-bed restriction. “Many people with insomnia are spending 8.5 hours in bed to get 6.5 hours of sleep,” he said. “What you do is restrict access to bed to 6.5 hours; you initially sleep deprive them. Over the first few weeks, they hate you. After a few weeks when they start sleeping well, you start gradually increasing time in bed, but they rarely get back to the 8.5 hours in bed they were spending beforehand.”

Online CBT-I programs such as Sleepio can also be effective for improving sleep latency and wake after sleep onset, but not for total sleep time (JAMA Psychiatry. 2017;74[1]:68-75). “Not everybody responds to CBT; 50% don’t respond at a couple of months,” he said. “These are the people you need to think about medication for.”

Medications commonly used for chronic insomnia include benzodiazepine receptor agonists (BzRAs) – temazepam, eszopiclone, triazolam, zolpidem, and zaleplon are Food and Drug Administration approved – melatonin agonists, orexin antagonists, sedating antidepressants, anticonvulsants, and dopaminergic antagonists. “Each of the agents in these categories has somewhat similar mechanisms of action, and similar efficacy and contraindications,” Dr. Winkelman said. “The best way to divide the benzodiazepine receptor agonists is based on half-life. How long do you want drug on receptor in somebody with insomnia? Probably not much longer than 8 hours. Nevertheless, some psychiatrists love clonazepam, which has a 40-hour half-life. The circumstances under which clonazepam should be used for insomnia are small, such as in people with a daytime anxiety disorder.”

Consider trying triazolam, zolpidem, and zaleplon for patients who have problems falling asleep, he said, while oxazepam and eszopiclone are sensible options for people who have difficulty falling and staying asleep. Clinical response to BzRAs is common, yet only about half of people who have insomnia remit with one of these agents.

Dr. Winkelman said that patients and physicians often ask him whether BzRAs and other agents used as sleep aids are addictive. Abuse is identified when recurrent use causes clinically and functionally significant impairment, such as health problems; disability; and failure to meet major responsibilities at work, home, or school. “These are concerns with BzRAs. Misuse and abuse generally occur in younger people. Once you get to 35 years old, misuse rates get very low. In older people, rates of side effects go up.

“Tolerance, physiological and psychological dependence, and nonmedical diversion are also of concern,” he said. However, for the majority of people, BzRA hypnotics are effective and safe.

As for other agents, meta-analyses have demonstrated that melatonin 1-3 mg can help people fall asleep when it’s not being endogenously released. “That’s during the day,” he said. “That might be most relevant for jet lag and for people doing shift work.” Two orexin antagonists on the market for insomnia include suvorexant and lemborexant 10-20 mg. Advantages of these include little abuse liability and few side effects. “In one head-to-head polysomnography study in the elderly, lemborexant was superior to zolpidem 6.25 mg CR on both objective and subjective ability to fall asleep and stay asleep,” Dr. Winkelman said. (JAMA Netw Open. 2019;2[12]:e1918254).

Antidepressants are another treatment option, including mirtazapine 15-30 mg, trazodone 25-100 mg, and amitriptyline and doxepin (10-50 mg). Advantages include little abuse liability, while potential drawbacks include daytime sedation, weight gain, and anticholinergic side effects. Meanwhile, atypical antipsychotics such as quetiapine 25-100 mg have long been known to be helpful for sleep. “Advantages are that they’re anxiolytic, they’re mood stabilizing, and there is little abuse liability,” Dr. Winkelman said. “Drawbacks are that they’re probably less effective than BzRAs, they cause daytime sedation, weight gain, risks of extrapyramidal symptoms and glucose and lipid abnormalities.”

Dr. Winkelman said that he uses “a fair amount” of the anticonvulsant gabapentin as a second- or third-line hypnotic agent. “I usually start with 300 mg [at bedtime],” he added. “Drawbacks are that it’s probably less effective than BzRAs; it affects cognition; and can cause daytime sedation, dizziness, and weight gain. There are also concerns about abuse.”

Dr. Winkelman reported that he has received grant/research support from Merck, the RLS Foundation, and Luitpold Pharmaceuticals. He is also a consultant for Advance Medical, Avadel Pharmaceuticals, and UpToDate and is a member of the speakers’ bureau for Luitpold.

LAS VEGAS – For Karen J. Hartwell, MD, few things in her clinical work bring more reward than providing medication-assisted treatment (MAT) to patients with opioid use disorder.

Doug Brunk/MDedge News

“Seeing people get into recovery on buprenorphine is as exciting as seeing your first person respond to clozapine, or to see a depression remit on your selection of an antidepressant,” she said at an annual psychopharmacology update held by the Nevada Psychiatric Association. “We know that medication-assisted treatment is underused and, sadly, relapse rates remain high.”

According to the Centers for Disease Control and Prevention, there were 70,237 drug-related overdose deaths in 2017 – 47,600 from prescription and illicit opioids. “This is being driven predominately by fentanyl and other high-potency synthetic opioids, followed by prescription opioids and heroin,” said Dr. Hartwell, an associate professor in the addiction sciences division in the department of psychiatry and behavioral sciences at the Medical University of South Carolina, Charleston.

There were an estimated 2 million Americans with an opioid use disorder (OUD) in 2018, she said, and more than 10 million misused prescription opioids. At the same time, prescriptions for opioids have dropped to lowest level in 10 years from a peak in 2012 of 81.3 prescriptions per 100 persons to 58.7 prescriptions per 100 persons in 2017 – total of more than 191 million scripts. “There is a decline in the number of opioid prescriptions, but there is still a lot of diversion, and there are some prescription ‘hot spots’ in the Southeast,” Dr. Hartwell said. “Heroin is a very low cost, and we’re wrestling with the issue of fentanyl.”

To complicate matters, most Americans with opioid use disorder are not in treatment. “In many people, the disorder is never diagnosed, and even fewer engage in care,” she said. “There are challenges with treatment retention, and even fewer achieve remission. There’s a lot of work to be done. One of which is the availability of medication-assisted treatment.”

Dr. Hartwell said that she knows of physician colleagues who have obtained a waiver to prescribe buprenorphine but have yet to prescribe it. “Some people may prefer to avoid the dance [of buprenorphine prescribing],” she said. “I’m here to advise you to dance.” Clinicians can learn about MAT waiver training opportunities by visiting the website of the Providers Clinical Support System, a program funded by the Substance Abuse and Mental Health Services Administration (SAMHSA).

Another option is to join a telementoring session on the topic facilitated by Project ECHO, or Extension for Community Healthcare Outcomes, which is being used by the University of New Mexico, Albuquerque. The goal of this model is to break down the walls between specialty and primary care by linking experts at an academic “hub” with primary care doctors and nurses in nearby communities.

“Our Project ECHO at the Medical University of South Carolina is twice a month on Fridays,” Dr. Hartwell said. “The first half is a case. The second half is a didactic [session], and you get a free hour of CME.”

The most common drugs used for medication-assisted treatment of opioid disorder are buprenorphine (a partial agonist), naltrexone (an antagonist), and methadone (a full agonist). Methadone retention generally is better than buprenorphine or naltrexone. The recommended treatment duration is 6-12 months, yet many studies demonstrate that many only stay on treatment for 30-60 days.

“You want to keep patients on treatment as long as they benefit from the medication,” Dr. Hartwell said. One large study of Medicaid claims data found that the risk of acute care service use and overdose were high following buprenorphine discontinuation, regardless of treatment duration. Superior outcomes became significant with treatment duration beyond 15 months, although rates of the primary adverse outcomes remained high (Am J Psychiatry. 2020 Feb 1;177[2]:117-24). About 5% of patients across all cohorts experienced one or more medically treated overdoses.

“One thing I don’t want is for people to drop out of treatment and not come back to see me,” Dr. Hartwell said. “This is a time for us to use our shared decision-making skills. I like to use the Tapering Readiness Inventory, a list of 16 questions. It asks such things as ‘Are you able to cope with difficult situations without using?’ and ‘Do you have all of the [drug] paraphernalia out of the house?’ We then have a discussion. If the patient decides to go ahead and do a taper, I always leave the door open. So, as that taper persists and someone says, ‘I’m starting to think about using, Doctor,’ I’ll put them back on [buprenorphine]. Or, if they come off the drug and they find themselves at risk of relapsing, they come back in and see me.”

There’s also some evidence that contingency management might be helpful, both in terms of opioid negative urines, and retention and treatment. Meanwhile, extended-release forms of buprenorphine are emerging.

In 2017, the Food and Drug Administration approved Sublocade, the first once-monthly injectable buprenorphine product for the treatment of moderate-to-severe OUD in adult patients who have initiated treatment with a transmucosal buprenorphine-containing product. “The recommendations are that you have about a 7-day lead-in of sublingual buprenorphine, and then 2 months of a 300-mg IV injection,” Dr. Hartwell said. “This is followed by either 100-mg injections monthly or 300-mg maintenance in select cases. There is some pain at the injection site. Some clinicians are getting around this by using a little bit of lidocaine prior to giving the injection.”

Another product, Brixadi, is an extended-release weekly (8 mg, 16 mg, 24 mg, 32 mg) and monthly (64 mg, 96 mg, 128 mg) buprenorphine injection used for the treatment of moderate to severe OUD. It is expected to be available in December 2020.

In 2016, the FDA approved Probuphine, the first buprenorphine implant for the maintenance treatment of opioid dependence. Probuphine is designed to provide a constant, low-level dose of buprenorphine for 6 months in patients who are already stable on low to moderate doses of other forms of buprenorphine, as part of a complete treatment program. “The 6-month duration kind of takes the issue of adherence off the table,” Dr. Hartwell said. “The caveat with this is that you have to be stable on 8 mg of buprenorphine per day or less. The majority of my patients require much higher doses.”

Dr. Hartwell reported having no relevant disclosures.

LAS VEGAS – For Karen J. Hartwell, MD, few things in her clinical work bring more reward than providing medication-assisted treatment (MAT) to patients with opioid use disorder.

“Seeing people get into recovery on buprenorphine is as exciting as seeing your first person respond to clozapine, or to see a depression remit on your selection of an antidepressant,” she said at an annual psychopharmacology update held by the Nevada Psychiatric Association. “We know that medication-assisted treatment is underused and, sadly, relapse rates remain high.”

According to the Centers for Disease Control and Prevention, there were 70,237 drug-related overdose deaths in 2017 – 47,600 from prescription and illicit opioids. “This is being driven predominately by fentanyl and other high-potency synthetic opioids, followed by prescription opioids and heroin,” said Dr. Hartwell, an associate professor in the addiction sciences division in the department of psychiatry and behavioral sciences at the Medical University of South Carolina, Charleston.

There were an estimated 2 million Americans with an opioid use disorder (OUD) in 2018, she said, and more than 10 million misused prescription opioids. At the same time, prescriptions for opioids have dropped to lowest level in 10 years from a peak in 2012 of 81.3 prescriptions per 100 persons to 58.7 prescriptions per 100 persons in 2017 – total of more than 191 million scripts. “There is a decline in the number of opioid prescriptions, but there is still a lot of diversion, and there are some prescription ‘hot spots’ in the Southeast,” Dr. Hartwell said. “Heroin is a very low cost, and we’re wrestling with the issue of fentanyl.”

To complicate matters, most Americans with opioid use disorder are not in treatment. “In many people, the disorder is never diagnosed, and even fewer engage in care,” she said. “There are challenges with treatment retention, and even fewer achieve remission. There’s a lot of work to be done. One of which is the availability of medication-assisted treatment.”

Dr. Hartwell said that she knows of physician colleagues who have obtained a waiver to prescribe buprenorphine but have yet to prescribe it. “Some people may prefer to avoid the dance [of buprenorphine prescribing],” she said. “I’m here to advise you to dance.” Clinicians can learn about MAT waiver training opportunities by visiting the website of the Providers Clinical Support System, a program funded by the Substance Abuse and Mental Health Services Administration (SAMHSA).

Another option is to join a telementoring session on the topic facilitated by Project ECHO, or Extension for Community Healthcare Outcomes, which is being used by the University of New Mexico, Albuquerque. The goal of this model is to break down the walls between specialty and primary care by linking experts at an academic “hub” with primary care doctors and nurses in nearby communities.

“Our Project ECHO at the Medical University of South Carolina is twice a month on Fridays,” Dr. Hartwell said. “The first half is a case. The second half is a didactic [session], and you get a free hour of CME.”

LAS VEGAS – The risk-benefit ratio of new and emerging drugs for depression is going to be under the spotlight more than ever before, according to an expert in mood disorders.

Doug Brunk/MDedge News

“We’ve seen a shift in the landscape,” Alan F. Schatzberg, MD, said at an annual psychopharmacology update held by the Nevada Psychiatric Association. “We’ve gone from the development of ‘me too’ agents such as venlafaxine and fluoxetine to developing drugs that may have more dramatic effects, but they also may have more baggage in terms of risks. The risk-benefit ratio is going to become increasingly more of a focus in drug development, in terms of increasing risk.”

The development of the SSRIs, he continued, led to the introduction of agents that were generally effective and well tolerated.

“Particularly, they were well tolerated in terms of their wide safety margin,” said Dr. Schatzberg, who directs the Mood Disorders Center at Stanford (Calif.) University. “It’s difficult to [die by suicide] on an SSRI. Because of that, we had greater numbers of individuals treated than we did with the tricyclics.” The introduction of SSRIs led to “widening of the net in terms of the numbers of depressed patients,” he said. “Combine that with DSM-III, and DSM-IV having relatively easy criteria to obtain a diagnosis [of depression, and] you see a large group of subjects who are exposed to treatment. But a lot of those people may not respond to a particular agent. As new treatments are promulgated and tried, what you find is [that] a reasonable number of subjects are, in fact, truly resistant. That becomes a tough nut to crack for all of us who treat depression.”

Drugs for depression that clinicians commonly have in their armamentarium commonly revolve around monoaminergic function. New and emerging agents include hallucinatory serotonin 2a agonists, glutamatergic drugs such as ketamine, GABAergic neurosteroids, opioid modulators, and onabotulinumtoxinA.

In 2013, the Food and Drug Administration approved the multimodal agent vortioxetine for the treatment of major depressive disorder. The recommended dosing is 20 mg/day, and the drug appears to have a positive effect on cognition. A meta-analysis of vortioxetine, duloxetine, and placebo comparison trials evaluated the effect of each treatment on the Digit Symbol Substitution Test (Int J Neuropsychopharmacol. 2016 Jun 15;19[10]). Vortioxetine was superior to placebo in all three trials and was superior to duloxetine in two trials. Duloxetine was not superior to placebo in two trials.

In two double-blind studies, researchers evaluated the effects of psilocybin in cancer patients with comorbid depression and anxiety. Full doses of psilocybin were 0.3 mg/kg or 22-30 mg per 70 kg. Both studies demonstrated sustained responses at full doses (J Psychopharmacol. 2016 Nov 30;30[12]:1181-97 and J Psychopharmacol. 2016 Nov 30;30[12]:1165-80).

In an open label study of psilocybin in refractory major depression, 12 patients received 10 mg on day 1 and 25 mg on day 8. Eight of 12 patients responded at 1 week, and 7 of the 12 maintained response at 3 months (Lancet Psychiatry. 2016 Jul;3[7]:619-27). According to Dr. Schatzberg, this trial became the basis for a blinded study that Compass is conducting in the United States and in the United Kingdom in which refractory patients are going to be randomized to 1 mg, 10 mg, or 25 mg psilocybin using an independent rater. “These patients are accompanied during this experience by two therapists for up to 8 hours. It’s not quite a guided therapy; it’s kind of a safety net therapy if the patient needs [help]. We’ll see what happens.”

Another agent being studied is ketamine, which works on the glutamate system, an excitatory neurotransmitter. “Glutamate is the juice that keeps us going,” said Dr. Schatzberg, who is also the Kenneth T. Norris Jr. professor of psychiatry and behavioral sciences at the university. “We can’t live without glutamate.” An anesthetic agent that has been used for 50 years, ketamine is a N-methyl-d-aspartate antagonist that has mu opioid agonist effects and stimulant properties. “It causes a psychotomimetic dissociative kind of reaction,” he said. “The doses used in depression are subanesthetic. They may put the patient asleep, but they usually don’t. The problem with the antidepressant effect is that 70% of people who initially respond don’t continue to respond beyond 1 week.”

In a randomized, placebo-controlled, double-blind crossover study of patients with treatment-resistant depression, subjects who received ketamine showed significant improvement in depression, compared with subjects who received placebo within 110 minutes after injection, which remained significant throughout the following week (Arch Gen Psychiatry. 2006;63:856-64). Specifically, of the 17 subjects treated with ketamine, 71% met response and 29% met remission criteria the day following ketamine infusion. Thirty-five percent of subjects maintained response for at least 1 week.

In an effort to further evaluate the antidepressive effects of ketamine, researchers conducted a two-site, parallel-arm, randomized, controlled trial of a single infusion of ketamine, compared with an active placebo control condition, the anesthetic midazolam (Am J Psychiatry. 2013 Oct;170[10]:1134-42). After adjustment for baseline scores and site, the Montgomery-Åsberg Depression Rating Scale score was lower in the ketamine group than in the midazolam group by 7.95 points. The likelihood of response at 24 hours was greater with ketamine than with midazolam (odds ratio, 2.18), with response rates of 64% and 28%, respectively.

In 2019, the FDA approved esketamine nasal spray, in conjunction with an oral antidepressant, for the treatment of depression in adults with treatment-resistant depression. In three phase 3 double-blind studies of esketamine in treatment-refractory depression, one was positive, two were nearly positive, and the effect sizes were mild. One maintenance discontinuation trial was positive. Based on this data, Dr. Schatzberg said, there “is not much evidence” that patients get further gain beyond an antidepressant alone in the first 24-48 hours following ketamine administration. “It makes me wonder: Should we be continuing to give this drug intranasally beyond 48 hours?” he asked. “The reason I have concern is that in certain cultures, ketamine is a highly abusable drug.”

He and Gerard Sanacora, PhD, MD, addressed the topic in a 2015 opinion piece entitled, “Ketamine: Promising path or false prophecy in the development of novel therapeutics for mood disorders?”

“If we step back for a moment and look at where we are – an intravenously administered agent that is a street drug of abuse, works rapidly, and whose enantiomers are being studied by industry for intranasal use – we should be anxious, “ they wrote (Neuropsychopharmacology. 2015 Jan;40[2]:259-67). “We need to be as careful and conservative as possible and understand how it is acting and rule out the possibility of whether it acts as an opioid.”

Dr. Schatzberg disclosed that he has served a consultant to Alkermes, Avanir, Bracket, Compass, Delpor, Epiodyne, Janssen, Jazz, Lundbeck, McKinsey, Merck, Myriad Genetics, Owl, Neuronetics, Pfizer, Sage, and Sunovion. He has received research funding from Janssen and also holds an ownership interest in Corcept, Dermira, Delpor, Epiodyne, Incyte Genetics, Madrigal, Maerck, Owl Analytics, Seattle Genetics, Titan, and Xhale.

But a lot of those people may not respond to a particular agent. As new treatments are promulgated and tried, what you find is [that] a reasonable number of subjects are, in fact, truly resistant. That becomes a tough nut to crack for all of us who treat depression.”

Drugs for depression that clinicians commonly have in their armamentarium commonly revolve around monoaminergic function. New and emerging agents include hallucinatory serotonin 2a agonists, glutamatergic drugs such as ketamine, GABAergic neurosteroids, opioid modulators, and onabotulinumtoxinA.

In 2013, the Food and Drug Administration approved the multimodal agent vortioxetine for the treatment of major depressive disorder. The recommended dosing is 20 mg/day, and the drug appears to have a positive effect on cognition. A meta-analysis of vortioxetine, duloxetine, and placebo comparison trials evaluated the effect of each treatment on the Digit Symbol Substitution Test (Int J Neuropsychopharmacol. 2016 Jun 15;19[10]). Vortioxetine was superior to placebo in all three trials and was superior to duloxetine in two trials. Duloxetine was not superior to placebo in two trials.

In two double-blind studies, researchers evaluated the effects of psilocybin in cancer patients with comorbid depression and anxiety. Full doses of psilocybin were 0.3 mg/kg or 22-30 mg per 70 kg. Both studies demonstrated sustained responses at full doses (J Psychopharmacol. 2016 Nov 30;30[12]:1181-97 and J Psychopharmacol. 2016 Nov 30;30[12]:1165-80).

In an open label study of psilocybin in refractory major depression, 12 patients received 10 mg on day 1 and 25 mg on day 8. Eight of 12 patients responded at 1 week, and 7 of the 12 maintained response at 3 months (Lancet Psychiatry. 2016 Jul;3[7]:619-27). According to Dr. Schatzberg, this trial became the basis for a blinded study that Compass is conducting in the United States and in the United Kingdom in which refractory patients are going to be randomized to 1 mg, 10 mg, or 25 mg psilocybin using an independent rater. “These patients are accompanied during this experience by two therapists for up to 8 hours. It’s not quite a guided therapy; it’s kind of a safety net therapy if the patient needs [help]. We’ll see what happens.”

Another agent being studied is ketamine, which works on the glutamate system, an excitatory neurotransmitter. “Glutamate is the juice that keeps us going,” said Dr. Schatzberg, who is also the Kenneth T. Norris Jr. professor of psychiatry and behavioral sciences at the university. “We can’t live without glutamate.” An anesthetic agent that has been used for 50 years, ketamine is a N-methyl-d-aspartate antagonist that has mu opioid agonist effects and stimulant properties. “It causes a psychotomimetic dissociative kind of reaction,” he said. “The doses used in depression are subanesthetic. They may put the patient asleep, but they usually don’t. The problem with the antidepressant effect is that 70% of people who initially respond don’t continue to respond beyond 1 week.”

In a randomized, placebo-controlled, double-blind crossover study of patients with treatment-resistant depression, subjects who received ketamine showed significant improvement in depression, compared with subjects who received placebo within 110 minutes after injection, which remained significant throughout the following week (Arch Gen Psychiatry. 2006;63:856-64). Specifically, of the 17 subjects treated with ketamine, 71% met response and 29% met remission criteria the day following ketamine infusion. Thirty-five percent of subjects maintained response for at least 1 week.

In an effort to further evaluate the antidepressive effects of ketamine, researchers conducted a two-site, parallel-arm, randomized, controlled trial of a single infusion of ketamine, compared with an active placebo control condition, the anesthetic midazolam (Am J Psychiatry. 2013 Oct;170[10]:1134-42). After adjustment for baseline scores and site, the Montgomery-Åsberg Depression Rating Scale score was lower in the ketamine group than in the midazolam group by 7.95 points. The likelihood of response at 24 hours was greater with ketamine than with midazolam (odds ratio, 2.18), with response rates of 64% and 28%, respectively.

In 2019, the FDA approved esketamine nasal spray, in conjunction with an oral antidepressant, for the treatment of depression in adults with treatment-resistant depression. In three phase 3 double-blind studies of esketamine in treatment-refractory depression, one was positive, two were nearly positive, and the effect sizes were mild. One maintenance discontinuation trial was positive. Based on this data, Dr. Schatzberg said, there “is not much evidence” that patients get further gain beyond an antidepressant alone in the first 24-48 hours following ketamine administration. “It makes me wonder: Should we be continuing to give this drug intranasally beyond 48 hours?” he asked. “The reason I have concern is that in certain cultures, ketamine is a highly abusable drug.”

He and Gerard Sanacora, PhD, MD, addressed the topic in a 2015 opinion piece entitled, “Ketamine: Promising path or false prophecy in the development of novel therapeutics for mood disorders?”

“If we step back for a moment and look at where we are – an intravenously administered agent that is a street drug of abuse, works rapidly, and whose enantiomers are being studied by industry for intranasal use – we should be anxious, “ they wrote (Neuropsychopharmacology. 2015 Jan;40[2]:259-67). “We need to be as careful and conservative as possible and understand how it is acting and rule out the possibility of whether it acts as an opioid.”

Dr. Schatzberg disclosed that he has served a consultant to Alkermes, Avanir, Bracket, Compass, Delpor, Epiodyne, Janssen, Jazz, Lundbeck, McKinsey, Merck, Myriad Genetics, Owl, Neuronetics, Pfizer, Sage, and Sunovion. He has received research funding from Janssen and also holds an ownership interest in Corcept, Dermira, Delpor, Epiodyne, Incyte Genetics, Madrigal, Maerck, Owl Analytics, Seattle Genetics, Titan, and Xhale.

LAS VEGAS – No evidence-based medications are approved for the treatment of avoidant/restrictive food intake disorder, but olanzapine is a sensible option to consider, according to Timothy D. Brewerton, MD.

Doug Brunk/MDedge News

A newly classified disorder in the DSM-5, avoidant/restrictive food intake disorder (ARFID) is an eating/feeding disturbance manifested by the persistent failure to meet appropriate nutritional energy needs associated with one or more of the following factors: significant weight loss or failure to achieve expected growth, significant nutritional deficiency, dependence on enteral feeding or oral nutritional supplements to survive, and marked interference with psychosocial functioning. ARFID “is not better explained by lack of available food or by culturally sanctioned practices,” Dr. Brewerton, an affiliate professor of psychiatry and behavioral sciences at the Medical University of South Carolina, Charleston, said at an annual psychopharmacology update held by the Nevada Psychiatric Association. “It does not occur during the course of anorexia nervosa or bulimia nervosa, and there is no evidence of a disturbance in the way in which one’s body weight or shape is experienced. That’s what distinguishes it from anorexia nervosa.”

He added that, although many cases of ARFID have autism spectrum disorder traits, ARFID “is not attributable to a concurrent medical condition or to mental disorder.” When it does occur, the severity of the feeding disorder far outweighs that of the medical condition.”

Several ARFID case reports have been published in the medical literature, yet no randomized controlled trials exist to date. “Treatment is multidisciplinary and involves cognitive-behavioral therapy, sometimes occupational therapy,” said Dr. Brewerton, who is a founding fellow and former board member of the Academy for Eating Disorders.

He and his colleagues published a report on nine ARFID cases treated in an eating disorders program (J Child Adolesc Psychopharmacol. 2017;27[10]:920-2). The patients were treated with adjunctive olanzapine at a starting dose of 0.9 mg/day and discharge dose 2.8 mg/day. For the starting dose, “you have to break the [olanzapine pills] in pieces,” he said. “You have to have a pill cutter. What you don’t want to do is overwhelm the patient or their family members with oversedation. Too often, people start them with 2.5 mg or 5 mg [of olanzapine] right off the bat.”

The researchers found a significant increase in weight gain pre- versus post-olanzapine treatment (a mean of 3.3 pounds vs. 13.1 pounds, respectively; P less than .04) and BMI-for-weight percentiles (P less than .009). “Patients also had improvements in their Clinical Global Impressions Scale scores and a reduction in their associated anxious, depressive, and cognitive symptoms,” Dr. Brewerton said.

Similar findings were observed in a subsequent Canadian study of six ARFID cases (J Eat Disord. 2018;6:20). Five females and one male were treated with a combination of medical monitoring, family therapy, medication (including olanzapine, fluoxetine and in two cases, cyproheptadine), and CBT. At treatment termination, all six patients had achieved their goal weight.

At the University of California, San Diego, researchers led by Emily Gray, MD, conducted a retrospective chart review of six females and eight males with ARFID who ranged in age from 7 to 23 years. All but one of the 14 patients had a co-occurring diagnosis, including general anxiety disorder, social anxiety, unspecified anxiety, ADHD, major depressive disorder, and autism spectrum disorder (J Am Acad Child Adoles Psychiatry. 2018;57[4]:288-9). They were treated with mirtazapine at a dosing range of 7.5-45 mg per day. The average change in BMI per week rose from 0.10 BMI points per week pretreatment to 0.23 BMI points per week post-treatment (P less than .05).

“These cases illustrate that the judicious use of low-dose olanzapine, when used as an adjunct to other treatment modalities, may facilitate eating, weight gain, and the reduction of anxious, depressive, and cognitive symptoms,” said Dr. Brewerton, who also has a private practice in Charleston.
