Cigarette smoking has been linked to the diagnosis of bacterial vaginosis (BV) and other genital infections including herpes simplex virus type 2, Chlamydia trachomatis, and oral and genital human papillomavirus (HPV).  Nicotine’s major metabolite, cotinine, has been found to concentrate in cervical mucus.

In 2014, researchers from Montana State University confirmed that the composition of the vaginal microbiota is “strongly associated with smoking.” They reported that women whose vaginal microbiota lacked significant numbers of Lactobacillus spp were 25-fold more likely to report current smoking than those with microbiota dominated by Lactobacillus crispatus (L crispatus). The researchers note that most Lactobacillus spp are thought to provide broad-spectrum protection to pathogenic infections by reducing vaginal pH.

But what is the mechanistic link between smoking and its effects on the vaginal microenvironment? The researchers conducted further study to assess the metabolome, a set of small molecule chemicals that includes host and microbial-produced and modified biomolecules as well as exogenous chemicals. The metabolome is an important characteristic of the vaginal microenvironment; the researchers say; differences in some metabolites are associated with functional variations of the vaginal microbiota. 

The analysis revealed samples clustered into 3 community state types (CSTs): CST-I (L crispatus dominated), CST-III (L iners dominated) and CST-IV (low Lactobacillus). Overall, smoking did not affect the vaginal metabolome after controlling for CSTs, but the researchers identified “an extensive and diverse range” of vaginal metabolites for which profiles were affected by both the microbiology and smoking status. They found 607 compounds in 36 women, including 12 metabolites that differed significantly between smokers and nonsmokers. Bacterial composition was the most pronounced driver of the vaginal metabolome, they say, associated with changes in 57% of all metabolites. As expected, nicotine, cotinine, and hydroxycotinine were markedly elevated in smokers’ vaginas.

Another “key finding,” the researchers say, was a significant increase in the abundance of various biogenic amines among smokers, far more pronounced in women with a low level of Lactobacillus. Biogenic amines are essential, they note, to mammalian and bacterial physiology. (Several are implicated in the “fishy” odor of BV.)

Their study serves as a pilot study, the researchers say, for future examinations of the connections between smoking and poor gynecologic and reproductive health outcomes.

Have you ever had times in your life when you had a tremendous amount of energy, like too much energy, with racing thoughts? I initially ask patients this question when evaluating for bipolar disorder. Some patients insist that they have racing thoughts—thoughts occurring at a rate faster than they can be expressed through speech¹—but not episodes of hyperactivity. This response suggests that some patients can have racing thoughts without a diagnosis of bipolar disorder.

Among the patients I treat, racing thoughts vary in severity, duration, and treatment. When untreated, a patient’s racing thoughts may range from a mild disturbance lasting a few days to a more severe disturbance occurring daily. In this article, I suggest treatments that may help ameliorate racing thoughts, and describe possible causes that include, but are not limited to, mood disorders.

Major depressive disorder

Many patients with major depressive disorder (MDD) have racing thoughts that often go unrecognized, and this symptom is associated with more severe depression.² Those with a DSM-5 diagnosis of MDD with mixed features could experience prolonged racing thoughts during a major depressive episode.¹ Untreated racing thoughts may explain why many patients with MDD do not improve with an antidepressant alone.³ These patients might benefit from augmentation with a mood stabilizer such as lithium⁴ or a second-generation antipsychotic.⁵

Other potential causes

Racing thoughts are a symptom, not a diagnosis. Apprehension and anxiety could cause racing thoughts that do not require treatment with a mood stabilizer or antipsychotic. Patients who often worry about having panic attacks or experience severe chronic stress may have racing thoughts. Also, some patients may be taking medications or illicit drugs or have a medical disorder that could cause symptoms of mania or hypomania that include racing thoughts (Table¹).

In summary, when caring for a patient who reports having racing thoughts, consider:

• whether that patient actually does have racing thoughts
• the potential causes, severity, duration, and treatment of the racing thoughts
• the possibility that for a patient with MDD, augmenting an antidepressant with a mood stabilizer or antipsychotic could decrease racing thoughts, thereby helping to alleviate many cases of MDD.

Childbirth is a trigger for first-onset or recurrence of various psychiatric disorders; however, research and clinical efforts have focused mainly on postpartum mood disorders. Unfortunately, there is little research on identifying and managing obsessive-compulsive disorder (OCD) in the postpartum period.

In one prospective study of 461 women who recently gave birth, researchers found the prevalence of OCD symptoms was 11% at 2 weeks postpartum.¹ Mothers with OCD may have time-consuming or functionally impairing obsessions and/or compulsions that can include:

• anticipatory anxiety of contamination (eg, germs, illness)
• thoughts of accidental or intentional harm to their infant
• compulsions comprised of cleaning and checking behaviors
• avoidance of situations
• thought suppression.

Because both clinicians and patients may not be aware of the effects of childbirth on women with OCD, postpartum OCD may go underdiagnosed or be misdiagnosed as major depressive disorder (MDD) or an anxiety disorder. Additionally, women with OCD who lack insight or have delusional beliefs might be misdiagnosed with postpartum psychosis.

Here I offer methods to help effectively identify OCD in postpartum women, and suggest how to implement an individualized treatment approach.

Keys to identification and diagnosis

Mothers who present with postpartum anxiety or depression may have obsessions and compulsions. It is important to specifically screen for these symptoms because some mothers may be reluctant to discuss the content of their thoughts or behaviors.

Screen women who present with postpartum anxiety or depression for obsessions and compulsions by using questions based on DSM-5 criteria,² such as:

• Do you have unpleasant thoughts, urges, or images that repeatedly enter your mind?
• Do you feel driven to perform certain behaviors or mental acts over and over again?

A validated scale, such as the Yale-Brown Obsessive Compulsive Scale (Y-BOCS),³ can also be used to screen for obsessive/compulsive symptoms in these patients.

Continue to: Evaluate women who endorse...

Evaluate women who endorse obsessions or compulsions for OCD. Women who meet diagnostic criteria for OCD should also be assessed for common psychiatric comorbidities, including MDD, anxiety disorders, or bipolar disorder. Obsessive-compulsive disorder with absent insight and delusional beliefs should be differentiated from postpartum psychosis, which is often a manifestation of bipolar disorder.

Treatment: What to consider

When selecting a treatment, consider factors such as symptom severity, psychiatric comorbidities, the patient’s insight into her OCD symptoms, patient preference, and breastfeeding status. Cognitive-behavioral therapy with exposure response prevention is indicated for patients with mild to moderate OCD. Pharmacotherapy should be reserved for individuals with severe OCD. Selective serotonin reuptake inhibitors (SSRIs) are the mainstay pharmacologic treatment of postpartum OCD; however, there are currently no randomized controlled trials of SSRIs for women with postpartum OCD. Augmentation with quetiapine should be considered for women who have an inadequate response to SSRIs.

CASE Rash, fever, extreme lethargy; multiple hospital visits

Ms. L, age 21, a single woman with a history of major depressive disorder (MDD), is directly admitted from an outside community hospital to our tertiary care academic hospital with acute liver failure.

One month earlier, Ms. L had an argument with her family and punched a wall, fracturing her hand. Following the episode, Ms. L’s primary care physician (PCP) prescribed valproic acid, 500 mg/d, to address “mood swings,” which included angry outbursts and irritability. According to her PCP, no baseline laboratory tests were ordered for Ms. L when she started valproic acid because she was young and otherwise healthy.

After Ms. L had been taking valproic acid for approximately 2 weeks, her mother noticed she became extremely lethargic and took her to the emergency department (ED) of a community hospital (Visit 1) (Table 1). At this time, her laboratory results were notable for an aspartate aminotransferase (AST) level of 303 IU/L (reference range: 8 to 40 IU/L) and an alanine aminotransferase (ALT) level of 241 IU/L (reference range: 20 to 60 IU/L). She also underwent a liver ultrasound, urine toxicology screen, blood alcohol level, and acetaminophen level; the results of all of these tests were unremarkable. Her valproic acid level was within therapeutic limits, consistent with patient adherence; her ammonia level was within normal limits. At Visit 1, Ms. L’s transaminitis was presumed to be secondary to valproic acid. The ED clinicians told her to stop taking valproic acid and discharged her. Her PCP did not give her any follow-up instructions for further laboratory tests or any other recommendations.

During the next week, even though she stopped taking the valproic acid as instructed, Ms. L developed a rash and fever, and continued to have lethargy and general malaise. When she returned to the ED (Visit 2) (Table 1), she was febrile, tachycardic, and hypotensive, with an elevated white blood cell count, eosinophilia, low platelets, and elevated liver function tests. At Visit 2, she was alert and oriented to person, place, time, and situation. Ms. L insisted that she had not overdosed on any medications, or used illicit drugs or alcohol. A test for hepatitis C was negative. Her ammonia level was 58 µmol/L (reference range: 11 to 32 µmol/L). Ms. L received N-acetylcysteine (NAC), prednisone, diphenhydramine, famotidine, and ibuprofen before she was transferred to our tertiary care hospital.

When she arrives at our facility (Visit 3) (Table 1), Ms. L is admitted with acute liver failure. She has an ALT level of 4,091 IU/L, and an AST level of 2,049 IU/L. Ms. L’s mother says that her daughter had been taking sertraline for depression for “some time” with no adverse effects, although she is not clear on the dose or frequency. Her mother says that Ms. L generally likes to spend most of her time at home, and does not believe her daughter is a danger to herself or others. Ms. L’s mother could not describe any episodes of mania or recurrent, dangerous anger episodes. Ms. L has no other medical history and has otherwise been healthy.

On hospital Day 2, Ms. L’s ammonia level is 72 µmol/L, which is slightly elevated. The hepatology team confirms that Ms. L may require a liver transplantation. The primary team consults the inpatient psychiatry consultation-liaison (C-L) team for a pre-transplant psychiatric evaluation.

[polldaddy:10307646]

The authors’ observations

The differential diagnosis for Ms. L was broad and included both accidental and intentional medication overdose. The primary team consulted the inpatient psychiatry C-L team not only for a pre-transplant evaluation, but also to assess for possible overdose.

Continue to: A review of the records...

A review of the records from Visit 1 and Visit 2 at the outside hospital found no acetaminophen in Ms. L’s system and verified that there was no evidence of a current valproic acid overdose. Ms. L had stated that she had not overdosed on any other medications or used any illicit drugs or alcohol. Ms. L’s complex symptoms—namely fever, acute liver failure, and rash—were more consistent with an adverse effect of valproic acid or possibly an inherent autoimmune process.

Liver damage from valproic acid

Valproic acid is FDA-approved for treating bipolar disorder, epilepsy, and migraine headaches¹ (Table 2¹). Common adverse effects include nausea, vomiting, sleepiness, and dry mouth. Rarely, valproic acid can impair liver function. While receiving valproic acid, 5% to 10% of patients develop elevated ALT levels, but most are asymptomatic and resolve with time, even if the patient continues taking valproic acid.² Valproic acid hepatotoxicity resulting in liver transplantation for a healthy patient is extremely rare (Table 3¹). Liver failure, both fatal and non-fatal, is more prevalent in patients concurrently taking other medications, such as antiepileptics, benzodiazepines, and antipsychotics, as compared with patients receiving only valproic acid.³

There are 3 clinically distinguishable forms of hepatotoxicity due to valproic acid²:

• hyperammonemia
• acute liver failure and jaundice
• Myriad ProReye-like syndrome, which is generally seen in children.

In case reports of hyperammonemia due to valproic acid, previously healthy patients experience confusion, lethargy, and eventual coma in the context of elevated serum ammonia levels; these symptoms resolved upon discontinuing valproic acid.^4,5 Liver function remained normal, with normal to near-normal liver enzymes and bilirubin.³ Hyperammonemia and resulting encephalopathy generally occurred within 1 to 3 weeks after initiation of valproate therapy, with resolution of hyperammonemia and resulting symptoms within a few days after stopping valproic acid.^2-4

At Visit 2, Ms. L’s presentation was not initially consistent with hepatic enceph­­alopathy. She was alert and oriented to person, place, time, and situation. Additionally, Ms. L’s presenting problem was elevated liver function tests, not elevated ammonia levels. At Visit 2, her ammonia level was 58 µmol/L; on Day 2 (Visit 3) of her hospital stay, her ammonia level was 72 µmol/L (slightly elevated).

Continue to: At Visit 2 in the ED...

At Visit 2 in the ED, Ms. L was started on NAC because the team suspected she was experiencing drug rash with eosinophilia and systemic symptoms (DRESS) syndrome. This syndrome is characterized by extensive rash, fever, and involvement of at least 1 internal organ. It is a variation of a drug-induced hypersensitivity syndrome. Ms. L’s unremarkable valproic acid levels combined with the psychiatry assessment ruled out valproic hepatotoxicity due to overdose, either intentional or accidental.

In case reports, patients who developed acute liver failure due to valproic acid typically had a hepatitis-like syndrome consisting of moderate elevation in liver enzymes, jaundice, and liver failure necessitating transplantation after at least 1 month of treatment with valproic acid.² In addition to the typical hepatitis-like syndrome resulting from valproic acid, case reports have also linked treatment with valproic acid to DRESS syndrome.² This syndrome is known to occur with anticonvulsants such as phenobarbital, lamotrigine, and phenytoin, but there are only a few reported cases of DRESS syndrome due to valproic acid therapy alone.⁶ Drug rash with eosinophilia and systemic symptoms syndrome differs from other acute liver failure cases in that patients also develop lymphadenopathy, fever, and rash.^2,6,7 Patients with DRESS syndrome typically respond to corticosteroid therapy and discontinuation of valproic acid, and the liver damage resolves after several weeks, without a need for transplantation.^2,6,7

Ms. L seemed to have similarities to DRESS syndrome. However, the severity of her liver damage, which might require transplantation even after only 2 weeks of valproic acid therapy, initially led the hepatology and C-L teams to consider her presentation similar to severe hepatitis-like cases.

EVALUATION Consent for transplantation

As an inpatient, Ms. L undergoes further laboratory testing. Her hepatic function panel demonstrates a total protein level of 4.8 g/dL, an albumin level of 2.0 g/dL, total bilirubin level of 12.2 mg/dL, and alkaline phosphatase of 166 IU/L. Her laboratory results indicate a prothrombin time (PT) of 77.4 seconds, partial thromboplastin time of 61.5 seconds, and PT international normalized ratio (INR) of 9.6. Ms. L’s basic metabolic panel is within normal limits except for a blood urea nitrogen level of 6 mg/dL, glucose level of 136 mg/dL, and calcium level of 7.0 mg/dL. Her complete blood count indicates a white blood cell count of 12.1, hemoglobin of 10.3 g/dL, hematocrit of 30.4%, mean corpuscular volume of 85.9 fL, and platelet count of 84. Her lipase level is normal at 49 U/L. Her serum acetaminophen concentration is <3.0 mcg/mL, valproic acid level was <2 µg/mL, and she is negative for hepatitis A, B, and C. A urine toxicology screen and testing for herpes simplex, rapid plasma reagin, and human immunodeficiency virus are all negative. Results from several auto-antibodies tests are negative and within normal limits, except filamentous actin (F-actin) antibody, which is slightly higher than normal at 21.4 ELISA units. Based on these results, Ms. L’s liver failure seemed most likely secondary to a reaction to valproic acid.

During her pre-transplant psychiatric evaluation, Ms. L is found to be a poor historian with minimal speech production, flat affect, and clouded sensorium. She denies overdosing on her prescribed valproic acid or sertraline, reports no current suicidal ideation, and does not want to die. She accurately recalls her correct daily dosing of each medication, and verifies that she stopped taking valproic acid 2 weeks ago after being advised to do so by the ED clinicians at Visit 2. She continued to take sertraline until Visit 2. She denied any past or present episodes consistent with mania, which was consistent with her mother’s report.

Continue to: Ms. L becomes agitated...

Ms. L becomes agitated upon further questioning, and requests immediate discharge so that she can return to her family. The evaluation is postponed briefly.

When they reconvene, the C-L team performs a decision-making capacity evaluation, which reveals that Ms. L’s mood and affect are consistent with fear of her impending liver transplant and being alone and approximately 2 hours from her family. This is likely complicated by delirium due to hepatotoxicity. Further discussion between Ms. L and the multidisciplinary team focuses on the risks, benefits, adverse effects of, and alternatives to her current treatment; the possibility of needing a liver transplantation; and how to help her family with transportation to the hospital. Following the discussion, Ms. L is fully cooperative with further treatment, and the pre-transplant psychiatric evaluation is completed.

On physical examination, Ms. L is noted to have a widespread morbilliform rash covering 50% to 60% of her body.

The authors’ observations

L-carnitine supplementation

Multiple studies have shown that supplementation with L-carnitine may increase survival from severe hepatotoxicity due to valproic acid.^8,9 Valproic acid may contribute to carnitine deficiency due to its inhibition of carnitine biosynthesis via a decrease in alpha-ketoglutarate concentration.⁸ Hepatotoxicity or hyperammonemia due to valproic acid may be potentiated by a carnitine deficiency, either pre-existing or resulting from valproic acid.⁸ L-carnitine supplementation has hastened the decrease of valproic acid–induced ammonemia in a dose-dependent manner,¹⁰ and it is currently recommended in cases of valproic acid toxicity, especially in children.⁸ Children at high risk for developing carnitine deficiency who need to receive valproic acid can be given carnitine supplementation.¹¹ It is not known whether L-carnitine is clinically effective in protecting the liver or hastening liver recovery,⁸ but it is believed that it might prevent adverse effects of hepatotoxicity and hyperammonemia, especially in patients who receive long-term valproic acid therapy.¹²

TREATMENT Decompensation and transplantation

Ms. L’s treatment regimen includes NAC, lactulose, and L-carnitine supplementation. During the course of Ms. L’s hospital stay, her liver enzymes begin to trend downward, but her INR and PT remain elevated.

Continue to: On hospital Day 6...

On hospital Day 6, she develops more severe symptoms of hepatic encephalopathy, with significant altered mental status and inattention. Ms. L is transferred to the ICU, intubated, and placed on the liver transplant list.

On hospital Day 9, she undergoes a liver transplantation.

[polldaddy:10307652]

The authors’ observations

Baseline laboratory testing should have been conducted prior to initiating valproic acid. As Ms. L’s symptoms worsened, better communication with her PCP and closer monitoring after starting valproic acid might have resulted in more immediate care. Early recognition of her symptoms and decompensation may have triggered earlier inpatient admission and/or transfer to a tertiary care facility for observation and treatment. Additionally, repeat laboratory testing and instructions on when to return to the ED should have been provided at Visit 1.

This case demonstrates the need for all clinicians who prescribe valproic acid to remain diligent about the accurate diagnosis of mood and behavioral symptoms, knowing when psychotropic medications are indicated, and carefully considering and discussing even rare, potentially life-threatening adverse effects of all medications with patients.

Although rare, after starting valproic acid, a patient may experience a rapid decompensation and life-threatening illness. Ideally, clinicians should closely monitor patients after initiating valproic acid (Table 4¹). Clinicians must have a clear knowledge of the recommended monitoring and indications for hospitalization and treatment when they note adverse effects such as elevated liver enzymes or transaminitis (Table 5^13,14). Even after stopping valproic acid, patients who have experienced adverse events should be closely monitored to ensure complete resolution. 

Continue to: Consider patient-specific factors

Consider the mental state, intellectual capacity, and social support of each patient before initiating valproic acid. Its use as a mood stabilizer for “mood swings” outside of the context of bipolar disorder is questionable. Valproic acid is FDA-approved for treating bipolar disorder and seizures, but not for anger outbursts/irritability. Prior to starting valproic acid, Ms. L may have benefited from alternative nonpharmacologic treatments, such as psychotherapy, for her anger outbursts and poor coping skills. Therapeutic techniques that focused on helping her acquire better coping mechanisms may have been useful, especially because her mood symptoms did not meet criteria for bipolar disorder, and her depression had long been controlled with sertraline monotherapy.

OUTCOME Discharged after 20 days

Ms. L stays in the hospital for 10 days after receiving her liver transplant. She has low appetite and some difficulty with sleep after the transplant; therefore, the C-L team recommends mirtazapine, 15 mg/d. She has no behavioral problems during her stay, and is set up with home health, case management, and psychiatry follow-up. On hospital Day 20, she is discharged.

Bottom Line

Use caution when prescribing valproic acid, even in young, otherwise healthy patients. Although rare, some patients may experience a rapid decompensation and life-threatening illness after starting valproic acid. When prescribing valproic acid, ensure close follow-up after initiation, including mental status examinations, physical examinations, and laboratory testing.

CASE Rash, fever, extreme lethargy; multiple hospital visits

Ms. L, age 21, a single woman with a history of major depressive disorder (MDD), is directly admitted from an outside community hospital to our tertiary care academic hospital with acute liver failure.

One month earlier, Ms. L had an argument with her family and punched a wall, fracturing her hand. Following the episode, Ms. L’s primary care physician (PCP) prescribed valproic acid, 500 mg/d, to address “mood swings,” which included angry outbursts and irritability. According to her PCP, no baseline laboratory tests were ordered for Ms. L when she started valproic acid because she was young and otherwise healthy.

After Ms. L had been taking valproic acid for approximately 2 weeks, her mother noticed she became extremely lethargic and took her to the emergency department (ED) of a community hospital (Visit 1) (Table 1). At this time, her laboratory results were notable for an aspartate aminotransferase (AST) level of 303 IU/L (reference range: 8 to 40 IU/L) and an alanine aminotransferase (ALT) level of 241 IU/L (reference range: 20 to 60 IU/L). She also underwent a liver ultrasound, urine toxicology screen, blood alcohol level, and acetaminophen level; the results of all of these tests were unremarkable. Her valproic acid level was within therapeutic limits, consistent with patient adherence; her ammonia level was within normal limits. At Visit 1, Ms. L’s transaminitis was presumed to be secondary to valproic acid. The ED clinicians told her to stop taking valproic acid and discharged her. Her PCP did not give her any follow-up instructions for further laboratory tests or any other recommendations.

During the next week, even though she stopped taking the valproic acid as instructed, Ms. L developed a rash and fever, and continued to have lethargy and general malaise. When she returned to the ED (Visit 2) (Table 1), she was febrile, tachycardic, and hypotensive, with an elevated white blood cell count, eosinophilia, low platelets, and elevated liver function tests. At Visit 2, she was alert and oriented to person, place, time, and situation. Ms. L insisted that she had not overdosed on any medications, or used illicit drugs or alcohol. A test for hepatitis C was negative. Her ammonia level was 58 µmol/L (reference range: 11 to 32 µmol/L). Ms. L received N-acetylcysteine (NAC), prednisone, diphenhydramine, famotidine, and ibuprofen before she was transferred to our tertiary care hospital.

When she arrives at our facility (Visit 3) (Table 1), Ms. L is admitted with acute liver failure. She has an ALT level of 4,091 IU/L, and an AST level of 2,049 IU/L. Ms. L’s mother says that her daughter had been taking sertraline for depression for “some time” with no adverse effects, although she is not clear on the dose or frequency. Her mother says that Ms. L generally likes to spend most of her time at home, and does not believe her daughter is a danger to herself or others. Ms. L’s mother could not describe any episodes of mania or recurrent, dangerous anger episodes. Ms. L has no other medical history and has otherwise been healthy.

On hospital Day 2, Ms. L’s ammonia level is 72 µmol/L, which is slightly elevated. The hepatology team confirms that Ms. L may require a liver transplantation. The primary team consults the inpatient psychiatry consultation-liaison (C-L) team for a pre-transplant psychiatric evaluation.

[polldaddy:10307646]

The authors’ observations

The differential diagnosis for Ms. L was broad and included both accidental and intentional medication overdose. The primary team consulted the inpatient psychiatry C-L team not only for a pre-transplant evaluation, but also to assess for possible overdose.

Continue to: A review of the records...

A review of the records from Visit 1 and Visit 2 at the outside hospital found no acetaminophen in Ms. L’s system and verified that there was no evidence of a current valproic acid overdose. Ms. L had stated that she had not overdosed on any other medications or used any illicit drugs or alcohol. Ms. L’s complex symptoms—namely fever, acute liver failure, and rash—were more consistent with an adverse effect of valproic acid or possibly an inherent autoimmune process.

Liver damage from valproic acid

Valproic acid is FDA-approved for treating bipolar disorder, epilepsy, and migraine headaches¹ (Table 2¹). Common adverse effects include nausea, vomiting, sleepiness, and dry mouth. Rarely, valproic acid can impair liver function. While receiving valproic acid, 5% to 10% of patients develop elevated ALT levels, but most are asymptomatic and resolve with time, even if the patient continues taking valproic acid.² Valproic acid hepatotoxicity resulting in liver transplantation for a healthy patient is extremely rare (Table 3¹). Liver failure, both fatal and non-fatal, is more prevalent in patients concurrently taking other medications, such as antiepileptics, benzodiazepines, and antipsychotics, as compared with patients receiving only valproic acid.³

There are 3 clinically distinguishable forms of hepatotoxicity due to valproic acid²:

• hyperammonemia
• acute liver failure and jaundice
• Myriad ProReye-like syndrome, which is generally seen in children.

In case reports of hyperammonemia due to valproic acid, previously healthy patients experience confusion, lethargy, and eventual coma in the context of elevated serum ammonia levels; these symptoms resolved upon discontinuing valproic acid.^4,5 Liver function remained normal, with normal to near-normal liver enzymes and bilirubin.³ Hyperammonemia and resulting encephalopathy generally occurred within 1 to 3 weeks after initiation of valproate therapy, with resolution of hyperammonemia and resulting symptoms within a few days after stopping valproic acid.^2-4

At Visit 2, Ms. L’s presentation was not initially consistent with hepatic enceph­­alopathy. She was alert and oriented to person, place, time, and situation. Additionally, Ms. L’s presenting problem was elevated liver function tests, not elevated ammonia levels. At Visit 2, her ammonia level was 58 µmol/L; on Day 2 (Visit 3) of her hospital stay, her ammonia level was 72 µmol/L (slightly elevated).

Continue to: At Visit 2 in the ED...

At Visit 2 in the ED, Ms. L was started on NAC because the team suspected she was experiencing drug rash with eosinophilia and systemic symptoms (DRESS) syndrome. This syndrome is characterized by extensive rash, fever, and involvement of at least 1 internal organ. It is a variation of a drug-induced hypersensitivity syndrome. Ms. L’s unremarkable valproic acid levels combined with the psychiatry assessment ruled out valproic hepatotoxicity due to overdose, either intentional or accidental.

In case reports, patients who developed acute liver failure due to valproic acid typically had a hepatitis-like syndrome consisting of moderate elevation in liver enzymes, jaundice, and liver failure necessitating transplantation after at least 1 month of treatment with valproic acid.² In addition to the typical hepatitis-like syndrome resulting from valproic acid, case reports have also linked treatment with valproic acid to DRESS syndrome.² This syndrome is known to occur with anticonvulsants such as phenobarbital, lamotrigine, and phenytoin, but there are only a few reported cases of DRESS syndrome due to valproic acid therapy alone.⁶ Drug rash with eosinophilia and systemic symptoms syndrome differs from other acute liver failure cases in that patients also develop lymphadenopathy, fever, and rash.^2,6,7 Patients with DRESS syndrome typically respond to corticosteroid therapy and discontinuation of valproic acid, and the liver damage resolves after several weeks, without a need for transplantation.^2,6,7

Ms. L seemed to have similarities to DRESS syndrome. However, the severity of her liver damage, which might require transplantation even after only 2 weeks of valproic acid therapy, initially led the hepatology and C-L teams to consider her presentation similar to severe hepatitis-like cases.

EVALUATION Consent for transplantation

As an inpatient, Ms. L undergoes further laboratory testing. Her hepatic function panel demonstrates a total protein level of 4.8 g/dL, an albumin level of 2.0 g/dL, total bilirubin level of 12.2 mg/dL, and alkaline phosphatase of 166 IU/L. Her laboratory results indicate a prothrombin time (PT) of 77.4 seconds, partial thromboplastin time of 61.5 seconds, and PT international normalized ratio (INR) of 9.6.

She accurately recalls her correct daily dosing of each medication, and verifies that she stopped taking valproic acid 2 weeks ago after being advised to do so by the ED clinicians at Visit 2. She continued to take sertraline until Visit 2. She denied any past or present episodes consistent with mania, which was consistent with her mother’s report.

Continue to: Ms. L becomes agitated...

Ms. L becomes agitated upon further questioning, and requests immediate discharge so that she can return to her family. The evaluation is postponed briefly.

When they reconvene, the C-L team performs a decision-making capacity evaluation, which reveals that Ms. L’s mood and affect are consistent with fear of her impending liver transplant and being alone and approximately 2 hours from her family. This is likely complicated by delirium due to hepatotoxicity. Further discussion between Ms. L and the multidisciplinary team focuses on the risks, benefits, adverse effects of, and alternatives to her current treatment; the possibility of needing a liver transplantation; and how to help her family with transportation to the hospital. Following the discussion, Ms. L is fully cooperative with further treatment, and the pre-transplant psychiatric evaluation is completed.

On physical examination, Ms. L is noted to have a widespread morbilliform rash covering 50% to 60% of her body.

The authors’ observations

L-carnitine supplementation

Multiple studies have shown that supplementation with L-carnitine may increase survival from severe hepatotoxicity due to valproic acid.^8,9 Valproic acid may contribute to carnitine deficiency due to its inhibition of carnitine biosynthesis via a decrease in alpha-ketoglutarate concentration.⁸ Hepatotoxicity or hyperammonemia due to valproic acid may be potentiated by a carnitine deficiency, either pre-existing or resulting from valproic acid.⁸ L-carnitine supplementation has hastened the decrease of valproic acid–induced ammonemia in a dose-dependent manner,¹⁰ and it is currently recommended in cases of valproic acid toxicity, especially in children.⁸ Children at high risk for developing carnitine deficiency who need to receive valproic acid can be given carnitine supplementation.¹¹ It is not known whether L-carnitine is clinically effective in protecting the liver or hastening liver recovery,⁸ but it is believed that it might prevent adverse effects of hepatotoxicity and hyperammonemia, especially in patients who receive long-term valproic acid therapy.¹²

TREATMENT Decompensation and transplantation

Ms. L’s treatment regimen includes NAC, lactulose, and L-carnitine supplementation. During the course of Ms. L’s hospital stay, her liver enzymes begin to trend downward, but her INR and PT remain elevated.

Continue to: On hospital Day 6...

On hospital Day 6, she develops more severe symptoms of hepatic encephalopathy, with significant altered mental status and inattention. Ms. L is transferred to the ICU, intubated, and placed on the liver transplant list.

On hospital Day 9, she undergoes a liver transplantation.

[polldaddy:10307652]

The authors’ observations

Baseline laboratory testing should have been conducted prior to initiating valproic acid. As Ms. L’s symptoms worsened, better communication with her PCP and closer monitoring after starting valproic acid might have resulted in more immediate care. Early recognition of her symptoms and decompensation may have triggered earlier inpatient admission and/or transfer to a tertiary care facility for observation and treatment. Additionally, repeat laboratory testing and instructions on when to return to the ED should have been provided at Visit 1.

This case demonstrates the need for all clinicians who prescribe valproic acid to remain diligent about the accurate diagnosis of mood and behavioral symptoms, knowing when psychotropic medications are indicated, and carefully considering and discussing even rare, potentially life-threatening adverse effects of all medications with patients.

Although rare, after starting valproic acid, a patient may experience a rapid decompensation and life-threatening illness. Ideally, clinicians should closely monitor patients after initiating valproic acid (Table 4¹). Clinicians must have a clear knowledge of the recommended monitoring and indications for hospitalization and treatment when they note adverse effects such as elevated liver enzymes or transaminitis (Table 5^13,14). Even after stopping valproic acid, patients who have experienced adverse events should be closely monitored to ensure complete resolution. 

Continue to: Consider patient-specific factors

Consider the mental state, intellectual capacity, and social support of each patient before initiating valproic acid. Its use as a mood stabilizer for “mood swings” outside of the context of bipolar disorder is questionable. Valproic acid is FDA-approved for treating bipolar disorder and seizures, but not for anger outbursts/irritability. Prior to starting valproic acid, Ms. L may have benefited from alternative nonpharmacologic treatments, such as psychotherapy, for her anger outbursts and poor coping skills. Therapeutic techniques that focused on helping her acquire better coping mechanisms may have been useful, especially because her mood symptoms did not meet criteria for bipolar disorder, and her depression had long been controlled with sertraline monotherapy.

OUTCOME Discharged after 20 days

Ms. L stays in the hospital for 10 days after receiving her liver transplant. She has low appetite and some difficulty with sleep after the transplant; therefore, the C-L team recommends mirtazapine, 15 mg/d. She has no behavioral problems during her stay, and is set up with home health, case management, and psychiatry follow-up. On hospital Day 20, she is discharged.

Bottom Line

Use caution when prescribing valproic acid, even in young, otherwise healthy patients. Although rare, some patients may experience a rapid decompensation and life-threatening illness after starting valproic acid. When prescribing valproic acid, ensure close follow-up after initiation, including mental status examinations, physical examinations, and laboratory testing.

The “human microbiota” describes all microorganisms within the human body, including bacteria, viruses, and eukaryotes. The related term “microbiome” refers to the complete catalog of these microbes and their genes.¹ There is a growing awareness that the human microbiota plays an important role in maintaining mental health, and that a disruption in its composition can contribute to manifestations of psychiatric disorders. A growing body of evidence has also linked mental health outcomes to the gut microbiome, suggesting that the gut microbiota can modulate the gut-brain axis.²

Numerous neurotransmitters, including dopamine, serotonin, gamma-aminobutyric acid, and acetylcholine, are produced in the gastrointestinal (GI) tract, and our diet is vital in sustaining and replenishing them. At the same time, our brain regulates our GI tract by secretion of hormones such as oxytocin, leptin, ghrelin, neuropeptide Y, corticotrophin-releasing factor, and a plethora of others. Dysregulation of this microbiome can lead to both physical and mental illnesses. Symptoms of psychiatric disorders, such as depression, psychosis, anxiety, and autism, can be a consequence of this dysregulation.²

Our diet can also modify the gut micro­organisms and therefore many of its metabolic pathways. More attention has been given to pre- and probiotics and their effects on DNA by epigenetic changes. One can quickly start to appreciate how this intricate crosstalk can lead to a variety of pathologic and psychiatric problems that have an adverse effect on autoimmune, inflammatory, metabolic, cognitive, and behavioral processes.^2,3

Thus far, links have mostly been reported in animal models, and human studies are limited.⁴ Researchers are just beginning to elucidate how the microbiota affect gut-brain signaling in humans. Such mechanisms may include alterations in microbial composition, immune activation, vagus nerve signaling, alterations in tryptophan metabolism, production of specific microbial neuroactive metabolites, and bacterial cell wall sugars.⁵ The microbiota-gut-brain axis plays a part in regulating/programming the hypothalamic-pituitary-adrenal (HPA) axis throughout the life span.³ The interactions between the gut microbiome, the immune system, and the CNS are regulated through pathways that involve endocrine functions (HPA axis), the immune system, and metabolic factors.^3,4 Recent research focusing on the gut microbiome has also given rise to international projects such as the Human Microbiome Project (Human Microbiome Project Consortium, 2012).³

Several studies have looked into psychiatry and inflammatory/immune pathways. Here we review 3 recent studies that have focused on the gut-brain axis (Table^6-8).

1. Rudzki L, Pawlak D, Pawlak K, et al. Immune suppression of IgG response against dairy proteins in major depression. BMC Psychiatry. 2017;17(1):268.

The aim of this study was to evaluate immunoglobulin G (IgG) response against 40 food products in patients with depression vs those in a control group, along with changes in inflammatory markers, psychological stress, and dietary variables.⁶

Study design

• N = 63, IgG levels against 44 food products, cortisol levels, tumor necrosis factor (TNF)-alpha, interleukin 6 (IL-6), and IL-1 beta levels were recorded. The psychological parameters of 34 participants with depression and 29 controls were compared using the Hamilton Depression Rating scale, (HAM-D-17), Perceived Stress scale, and Symptom Checklist scale. The study was conducted in Poland.

Continue to: Outcomes

Outcomes

• Patients who were depressed had lower IgG levels against dairy products compared to controls when there was high dairy consumption. However, there was no overall difference between patients and controls in mean IgG concentration against food products. 
• Patients who were depressed had higher levels of cortisol. Levels of cortisol had a positive correlation with HAM-D-17 score. Patients with depression had lower levels of TNF-alpha.

Conclusion

• Patients with depression had lower levels of IgG against dairy protein. Patients with depression had high cortisol levels but decreased levels of TNF-alpha, which could explain an immune suppression of IgG in these patients. There were no differences in IL-6 or IL-1beta levels.

Hypercortisolemia is present in approximately 60% of patients with depression. Elevated cortisol levels have a negative effect on lymphocyte function. B-lymphocytes (CD 10+ and CD 19+) are sensitive to glucocorticoids. Studies in mice have demonstrated that elevated glucocorticoid levels are associated with a 50% decrease in serum B-lymphocytes, and this can be explained by downregulation of c-myc protein, which plays a role in cell proliferation and cell survival. Glucocorticoids also decrease levels of protein kinases that are vital for the cell cycle to continue, and they upregulate p27 and p21, which are cell cycle inhibitors. Therefore, if high cortisol suppresses B-lymphocyte production, this can explain how patients with depression have low IgG levels, since B-lymphocytes differentiate into plasma cells that will produce antibodies.⁶

Depression can trigger an inflammatory response by increasing levels of inflammatory cytokines, acute phase reactants, and oxidative molecules. The inflammatory response can lead to intestinal wall disruption, and therefore bacteria can migrate across the GI barrier, along with food antigens, which could then lead to food antigen hypersensitivity.⁶

The significance of diet

Many studies have looked into specific types of diets, such as the Mediterranean diet, the ketogenic diet, and the addition of supplements such as probiotics, omega-3 fatty acids, zinc, and multivitamins.⁷ The Mediterranean diet is high in fiber, nuts, legumes, and fish.⁷ The ketogenic diet includes a controlled amount of fat, but is low in protein and carbohydrates.⁷ The main point is that a balanced diet can have a positive effect on mental health.⁷ The Mediterranean diet has shown to decrease the incidence of cardiovascular disease and lower the risk of depression.⁷ In animal studies, the ketogenic diet has improved anxiety, depression, and autism.⁷ Diet clearly affects gut microbiota and, as a consequence, the body’s level of inflammation.⁷

Study design

• These researchers provided a narrative review of the significance of a healthy diet and nutritional supplements on the gut microbiome and the treatment of patients with psychiatric illness. 

Outcomes

• This review suggested dietary coaching as a nonpharmacologic treatment for patients with psychiatric illness. 

Conclusion

• The utilization of nutritional advice, along with medication management, therapy, and physical activity, can provide a holistic approach to the biopsychosocial treatment of patients with psychiatric illness.

This review also emphasized the poor dietary trends of Westernized countries, which include calorie-dense, genetically altered, processed meals. As Mörkl et al⁷ noted, we are overfed but undernourished. Mörkl et al⁷ reviewed studies that involve dietary coaching as part of the treatment plan of patients with mental illness. In one of these studies, patients who received nutritional advice and coaching over 6 weeks had a 40% to 50% decrease in depressive symptoms. These effects persisted for 2 more years. Mörkl et al⁷ also reviewed an Italian study that found that providing nutritional advice in patients with affective disorders and psychosis helped improve symptom severity and sleep.⁷

Continue to: Mörkl et al...

Mörkl et al⁷ also reviewed dietary supplements. Some studies have linked use of omega-3 fatty acids with improvement in affective disorders, Alzheimer’s disease, and posttraumatic stress disorder, as well as cardiovascular conditions. Omega-3 fatty acids may exert beneficial effects by enhancing brain-derived neurotrophic factor and neurogenesis as well as by decreasing inflammation.⁷

Zinc supplementation can also improve depression, as it has been linked to cytokine variation and hippocampal neuronal growth. Vitamin B₉ deficiency and vitamin D deficiency also have been associated with depression. Mörkl et al⁷ emphasized that a balanced diet that incorporates a variety of nutrients is more beneficial than supplementation of any individual vitamin alone.

Researchers have long emphasized the importance of a healthy balanced diet when treating patients with medical conditions such as cardiovascular or cerebrovascular diseases. Based on the studies Mörkl et al⁷ reviewed, the same emphasis should be communicated to our patients who suffer from psychiatric conditions.

The gut and anxiety

The gut microbiome has also been an area of research when studying generalized anxiety disorder (GAD).⁸

3. Jiang HY, Zhang X, Yu ZH, et al. Altered gut microbiota profile in patients with generalized anxiety disorder. J Psychiatr Res. 2018;104:130-136.

The aim of the study was to determine if there were changes in the composition of the gut microbiome in patients with GAD compared with healthy controls.⁸

Continue to: Study design

Study design

• A cross-sectional study of 76 patients in Zhejiang, China. Forty patients with GAD in the active state and 36 healthy controls were compared in terms of composition of GI microbacterial flora.
• Researchers also examined a subgroup of 12 patients who were treatment-naïve and 17 controls. Stool samples were collected from the 12 patients who were treatment-naïve before initiating medication.
• Researchers also conducted a prospective study in a subgroup of 9 patients with GAD in both the active state and remissive state. Two stool samples were collected from each patient—one during the active state of GAD and one during the remissive state—for a total of 18 samples. Stool samples analyzed with the use of polymerase chain reaction and microbial analysis.
• Patients completed the Hamilton Anxiety Rating (HAM-A) scale and were classified into groups. Those with HAM-A scores >14 were classified as being in the active state of GAD, and those with scores <7 were classified as being in the remissive state. 

Outcomes

• Among the samples collected, 8 bacterial taxa were found in different amounts in patients with GAD and healthy controls. Bacteroidetes, Ruminococcus gnavus, and Fusobacterium were increased in patients with GAD compared with controls, while Faecalibacterium, Eubacterium rectale, Sutterella, Lachnospira, and Butyricicoccus were increased in healthy controls.
• Bacterial variety was notably lower in the 12 patients who were treatment-naïve compared with the control group.
• There was no notable difference in microbial composition between patients in the active vs remissive state.

Conclusion

• Patients with GAD had less short chain fatty acid–producing bacteria (Faecalibacterium, Eubacterium rectale, Sutterella, Lachnospira, and Butyricicoccus) compared with controls. Decreased formation of short chain fatty acids could lead to GI barrier disruption. Fusobacterium and Ruminococcus were increased in patients with GAD. Fusobacterium can cause disease and be invasive when it disseminates within the body. The inflammatory characteristics of Fusobacterium contribute to the immunologic activation in GAD. Ruminococcus breaks down mucin, which could then increase GI permeability by mucous degradation of the GI lumen.

Changes in food processing and manufacturing have led to changes in our diets. Changes in our normal GI microbacterial flora could lead to increased gut permeability, bacterial dissemination, and subsequent systemic inflammation. Research has shown that the composition of the microbiota changes across the life span.⁹ A balanced intake of nutrients is important for both our physical and mental health and safeguards the basis of gut microbiome regulation. A well-regulated gut microbiome ensures low levels of inflammation in the brain and body. Lifestyle modifications and dietary coaching could be practical interventions for patients with psychiatric conditions.⁵ Current advances in technology now offer precise analyses of thousands of metabolites, enabling metabolomics to offer the promise of discovering new drug targets and biomarkers that may help pave a way to precision medicine.

Many studies have looked into specific types of diets, such as the Mediterranean diet, the ketogenic diet, and the addition of supplements such as probiotics, omega-3 fatty acids, zinc, and multivitamins.⁷ The Mediterranean diet is high in fiber, nuts, legumes, and fish.⁷ The ketogenic diet includes a controlled amount of fat, but is low in protein and carbohydrates.⁷ The main point is that a balanced diet can have a positive effect on mental health.⁷ The Mediterranean diet has shown to decrease the incidence of cardiovascular disease and lower the risk of depression.⁷ In animal studies, the ketogenic diet has improved anxiety, depression, and autism.⁷ Diet clearly affects gut microbiota and, as a consequence, the body’s level of inflammation.⁷

The following review highlighted the significance of diet on gut microbiome and mental health.⁷

Study design

• These researchers provided a narrative review of the significance of a healthy diet and nutritional supplements on the gut microbiome and the treatment of patients with psychiatric illness. 

Outcomes

• This review suggested dietary coaching as a nonpharmacologic treatment for patients with psychiatric illness. 

Conclusion

• The utilization of nutritional advice, along with medication management, therapy, and physical activity, can provide a holistic approach to the biopsychosocial treatment of patients with psychiatric illness.

This review also emphasized the poor dietary trends of Westernized countries, which include calorie-dense, genetically altered, processed meals. As Mörkl et al⁷ noted, we are overfed but undernourished. Mörkl et al⁷ reviewed studies that involve dietary coaching as part of the treatment plan of patients with mental illness. In one of these studies, patients who received nutritional advice and coaching over 6 weeks had a 40% to 50% decrease in depressive symptoms. These effects persisted for 2 more years. Mörkl et al⁷ also reviewed an Italian study that found that providing nutritional advice in patients with affective disorders and psychosis helped improve symptom severity and sleep.⁷

Continue to: Mörkl et al...

Mörkl et al⁷ also reviewed dietary supplements. Some studies have linked use of omega-3 fatty acids with improvement in affective disorders, Alzheimer’s disease, and posttraumatic stress disorder, as well as cardiovascular conditions. Omega-3 fatty acids may exert beneficial effects by enhancing brain-derived neurotrophic factor and neurogenesis as well as by decreasing inflammation.⁷

Zinc supplementation can also improve depression, as it has been linked to cytokine variation and hippocampal neuronal growth. Vitamin B₉ deficiency and vitamin D deficiency also have been associated with depression. Mörkl et al⁷ emphasized that a balanced diet that incorporates a variety of nutrients is more beneficial than supplementation of any individual vitamin alone.

Researchers have long emphasized the importance of a healthy balanced diet when treating patients with medical conditions such as cardiovascular or cerebrovascular diseases. Based on the studies Mörkl et al⁷ reviewed, the same emphasis should be communicated to our patients who suffer from psychiatric conditions.

The gut and anxiety

The gut microbiome has also been an area of research when studying generalized anxiety disorder (GAD).⁸

3. Jiang HY, Zhang X, Yu ZH, et al. Altered gut microbiota profile in patients with generalized anxiety disorder. J Psychiatr Res. 2018;104:130-136.

The aim of the study was to determine if there were changes in the composition of the gut microbiome in patients with GAD compared with healthy controls.⁸

Continue to: Study design

Study design

• A cross-sectional study of 76 patients in Zhejiang, China. Forty patients with GAD in the active state and 36 healthy controls were compared in terms of composition of GI microbacterial flora.
• Researchers also examined a subgroup of 12 patients who were treatment-naïve and 17 controls. Stool samples were collected from the 12 patients who were treatment-naïve before initiating medication.
• Researchers also conducted a prospective study in a subgroup of 9 patients with GAD in both the active state and remissive state. Two stool samples were collected from each patient—one during the active state of GAD and one during the remissive state—for a total of 18 samples. Stool samples analyzed with the use of polymerase chain reaction and microbial analysis.
• Patients completed the Hamilton Anxiety Rating (HAM-A) scale and were classified into groups. Those with HAM-A scores >14 were classified as being in the active state of GAD, and those with scores <7 were classified as being in the remissive state. 

Outcomes

• Among the samples collected, 8 bacterial taxa were found in different amounts in patients with GAD and healthy controls. Bacteroidetes, Ruminococcus gnavus, and Fusobacterium were increased in patients with GAD compared with controls, while Faecalibacterium, Eubacterium rectale, Sutterella, Lachnospira, and Butyricicoccus were increased in healthy controls.
• Bacterial variety was notably lower in the 12 patients who were treatment-naïve compared with the control group.
• There was no notable difference in microbial composition between patients in the active vs remissive state.

Conclusion

• Patients with GAD had less short chain fatty acid–producing bacteria (Faecalibacterium, Eubacterium rectale, Sutterella, Lachnospira, and Butyricicoccus) compared with controls. Decreased formation of short chain fatty acids could lead to GI barrier disruption. Fusobacterium and Ruminococcus were increased in patients with GAD. Fusobacterium can cause disease and be invasive when it disseminates within the body. The inflammatory characteristics of Fusobacterium contribute to the immunologic activation in GAD. Ruminococcus breaks down mucin, which could then increase GI permeability by mucous degradation of the GI lumen.

Changes in food processing and manufacturing have led to changes in our diets. Changes in our normal GI microbacterial flora could lead to increased gut permeability, bacterial dissemination, and subsequent systemic inflammation. Research has shown that the composition of the microbiota changes across the life span.⁹ A balanced intake of nutrients is important for both our physical and mental health and safeguards the basis of gut microbiome regulation. A well-regulated gut microbiome ensures low levels of inflammation in the brain and body. Lifestyle modifications and dietary coaching could be practical interventions for patients with psychiatric conditions.⁵ Current advances in technology now offer precise analyses of thousands of metabolites, enabling metabolomics to offer the promise of discovering new drug targets and biomarkers that may help pave a way to precision medicine.

Treatment-resistant depression (TRD) is a common clinical struggle that practicing clinicians address on a daily basis. Major depressive disorder affects nearly 1 in 5 Americans at some point in their life and, by definition, impairs social and occupational functioning. Historic treatments have focused on the monoamine theories of depression—modulating the monoamines serotonin, norepinephrine, and/or dopamine. Limitations of currently available antidepressants include delayed onset of effect and low remission rates. To further complicate the matter, numerous studies have shown that with each subsequent antidepressant trial, patients have a decreasing likelihood of responding to subsequent antidepressant treatment options. For example, in the classic STAR*D trial, by the time a patient had not responded to the first 2 antidepressant options, the chance that they would respond to a third or fourth antidepressant had decreased to approximately 15% per antidepressant treatment course.¹

To address the need for new treatments for patients with TRD, on March 5, 2019 the FDA-approved intranasal esketamine (brand name: Spravato) (Table 1²) following the evaluation of its efficacy through short-term clinical trials and a longer-term maintenance-of-effect trial. Intranasal esketamine is indicated, in conjunction with an oral antidepressant, for adult patients with TRD.² Esketamine is a CIII controlled substance, and concerns about abuse, misuse, and diversion have been taken into account within the Risk Evaluation and Mitigation Strategy (REMS) drug safety program. The agent is only available through a restricted distribution—the REMS will mandate that REMS certified pharmacies dispense directly to a REMS certified treatment program. Intranasal esketamine will not be sampled or dispensed directly to patients.

How it works

Modern research has looked beyond the monoamine system to explore the neuro-modulatory effects of glutamate and gamma-aminobutyric acid (GABA).³ The yin and yang of glutamate and GABA revolves around neural excitation vs neural inhibition at a local synaptic level. The primary effects of the glutamate and GABA systems (Table 2) can be broken down into several key areas of understanding.

Glutamate modulates ionotropic N-methyl-d-aspartate (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, and a family of non-ionic metabotropic receptors, or mGluRs. Glutamate stimulation of NMDA or AMPA receptors increases Ca²⁺ ion influx and enhances neural firing. Conversely, GABA stimulation increases Cl^– ion influx, which inhibits neural firing. Antagonizing glutamate receptors inhibits neural firing. N-methyl-d-aspartate receptors localized on the GABA interneuron modulate GABAergic activity. Antagonism of the NMDA receptor on GABA interneurons decreases GABA activity. Decreased activity of the GABA interneuron promotes intrasynaptic glutamate release and enhances glutamate stimulation of postsynaptic AMPA receptors. Glutamate stimulation of AMPA receptors then stimulates a cascade of intrasynaptic signaling that promotes the release of brain-derived neurotrophic factor (BDNF) and increased production of neuronal membrane proteins with subsequent neural plasticity.

Esketamine, the S-enantiomer of ketamine, has a higher affinity for the NMDA receptor than the R-enantiomer and has been developed as an intranasal adjunctive treatment for TRD. Esketamine blocks NMDA receptors on GABA interneurons. This allows for increased pulsatile release of glutamate into the synapse. Intrasynaptic glutamate then stimulates postsynaptic AMPA receptors. Glutamate stimulation of postsynaptic AMPA receptors results in an intracellular cascade that activates the enzymes tropomyosin receptor kinase B (TrkB) and mammalian target of rapamycin (mTOR). TrkB stimulation results in increased production and release of BDNF. mTor stimulation increases neuronal membrane protein formation with subsequent increased neural plasticity. Taken together, preclinical models show that esketamine’s inhibition of the NMDA receptor on the GABA interneuron results in a cascade of increased BDNF release and synaptogenesis with increased neuroplasticity (Table 3).

Clinical implications

Treatment-resistant depression affects nearly one-third of patients currently receiving standard antidepressant treatment. Major depressive disorder is currently the second leading cause of disability for working adults within the United States and one of the largest causes of disability worldwide. The esketamine nasal spray could be beneficial for patients who have experienced TRD with standard monoamine antidepressants.

Supporting evidence

Clinical trials examining intranasal esketamine include both short- and long-term studies of patients with TRD.

Continue to: Esketamine was evaluated...

Esketamine was evaluated in a randomized, placebo-controlled, double-blind, multicenter, short-term (4-week) phase III study in adult patients age 18 to 65 with TRD (they had not responded to at least 2 different antidepressants of adequate dose and duration).⁴ After discontinuing prior antidepressant treatments, all patients were started on a newly initiated antidepressant and were also randomized to concomitant intranasal esketamine or intranasal placebo as follows:

• 114 patients were randomized to the intranasal esketamine plus newly initiated oral antidepressant arm
• 109 patients were randomized to the placebo nasal spray plus newly initiated oral antidepressant arm
• The mean baseline Montgomery-Åsberg Depression Rating Scale (MADRS) score for each group was 37 (ie, moderately to severely depressed).

Newly started antidepressants included escitalopram, sertraline, duloxetine, or extended-release venlafaxine. Esketamine intranasal spray was initiated at 56 mg and could be titrated up to 84 mg at the second dose, based on investigator discretion. The mean age was 47; 62% of the patients were female, 93% were White, and 5% were black. The newly initiated oral antidepressant was a selective serotonin reuptake inhibitor in 32% of patients and an serotonin-norepinephrine reuptake inhibitor in 68% of patients. The time course of response for this 4-week, short-term treatment study is illustrated in Figure 1.² While the primary efficacy measure was improvement of MADRS score at Week 4, the majority of the placebo-active drug separation occurred 24 hours after the initial 56 mg dose of esketamine. Between 24 hours and Day 28, intranasal esketamine showed continued separation from antidepressant plus placebo nasal spray. Investigators could increase both placebo nasal spray or esketamine, with 67% of patients receiving 84 mg twice weekly at Day 28.

A long-term, double-blind multicenter maintenance-of-effect trial examined adults age 18 to 65 with TRD.^5-6 Patients in this study were responders in 1 of 2 short-term studies or in an open-label direct enrollment study. Stable remission was defined as a MADRS total score <12 for at least 3 of the last 4 weeks of the study, and stable response was defined as a MADRS reduction of >50% but not in remission. After 16 weeks of intranasal esketamine plus an oral antidepressant, stable remitters and stable responders were then randomized separately to continue intranasal esketamine or switch to placebo nasal spray, with both groups continuing on their concomitant oral antidepressant. The primary study endpoint was time to relapse. Relapse was defined as a MADRS total score >22 for more than 2 consecutive weeks, hospitalization for worsening of depression, or any other clinically relevant event. The median age was 48, 66% were female, 90% were White and 4% were black. Patients in stable response or stable remission experienced a significantly longer time to relapse compared with patients who continued their oral antidepressant but were switched to placebo intranasal spray. In this remission response study, patients could receive intranasal treatment weekly or bi-weekly based on symptom severity (Figure 2²).

Impact on driving. Two studies examined the impact of esketamine on driving performance. One examined adults with major depressive disorder and the other examined healthy participants. The effects of a single 84-mg dose of esketamine nasal spray on a patient’s ability to drive was assessed in 23 healthy adults. In this study, mirtazapine was used as an active control. Driving performance was assessed at 8 hours after treatment with esketamine nasal spray or mirtazapine. Driving performance 8 hours after esketamine nasal spray was similar to placebo and active control. Two participants discontinued the driving task after receiving esketamine due to post-dose adverse reactions. One reported pressure behind the eyes and paresthesia of the hands and feet. The other reported headache and light sensitivity with anxiety.

A second study evaluated the effects of repeated esketamine administration on driving performance in 25 adults with major depressive disorder. In this study, an ethanol-containing beverage was used as an active control. After administration of a single 84-mg dose of intranasal esketamine, driving performance was the same as a placebo at 18 hours. In the multiple dose phase, standard driving performance was similar for esketamine nasal spray and placebo at 6 hours postdose on Days 11, 18, and 25.

Continue to: Pharmacologic profile

Adverse events. The most common adverse events in patients treated with esketamine nasal spray were dissociation (41%), dizziness (29%), nausea (28%), sedation (23%), and vertigo (23%).² The majority of these effects were short-term and resolved during the 2-hour observation period.

In addition to spontaneously reported events, sedation and dissociation were further monitored with specific scales. Sedation was measured with the Modified Observer’s Alertness and Sedation Scale. Using this scale, 50% of patients receiving 56 mg and 61% of patients receiving 84 mg of esketamine met criteria for sedation.

Similarly, dissociation/perceptional changes were measured with spontaneously reported events and also with the Clinician Administered Dissociative State Scale. On this scale, 61% of patients receiving the 56-mg dose, and 69% of patients receiving the 84-mg dose met criteria for dissociation/perceptional changes after dose administration.

Increases in blod pressure. Esketamine intranasal spray was associated with a 7 to 9 mm Hg increase in systolic blood pressure and a 4 to 6 mm Hg increase in diastolic blood pressure, both of which peaked 40 minutes post-dose.

Nausea and vomiting. Intranasal esketamine was associated with a 27% rate of nausea at 56 mg, and 32% at 84 mg, with a 6% rate of vomiting at 56 mg and 12% at 84 mg.

Continue to: Pharmacokinetics

Esketamine exposure increases from 28 to 84 mg in a fairly dose-proportional range. No accumulation of esketamine was observed in the plasma following twice-weekly administration. Bioavailability is approximately 48% following nasal administration. The Tmax for esketamine plasma concentration is 20 to 40 minutes after the last nasal spray. Protein binding of esketamine is approximately 43% to 45%. The brain-to-plasma ratio of noresketamine is 4 to 6 times lower than that of esketamine. The half-life of esketamine ranged from 7 to 12 hours. The mean half-life of noresketamine was approximately 8 hours. Esketamine is primarily metabolized to a noresketamine metabolite via cytochrome P450 (CYP) enzymes, 2B6 and 3A4. Noresketamine is metabolized by CYP-dependent pathways and certain metabolites undergo glucuronidation. Drug interaction studies demonstrate that intranasal esketamine had very little effect on pharmacokinetic interactions with other medications.

Potential drug interactions

Central nervous system depressants. Concomitant use of esketamine and other CNS depressants (ie, benzodiazepines, opioids, alcohol) may increase sedation. Patients receiving esketamine with concomitant use of other CNS depressants should be closely monitored for sedation.

Psychostimulants. Concomitant use of esketamine and psychostimulants (ie, amphetamines, methylphenidates, modafinil, and armodafinil) may increase blood pressure. Patients receiving esketamine with concomitant use of psychostimulants should be closely monitored for elevations in blood pressure.

Monoamine oxidase inhibitors. Concomitant use of esketamine with monoamine oxidase inhibitors may increase blood pressure. Closely monitor blood pressure with concomitant use of esketamine and monoamine oxidase inhibitors.

Use in special populations. Because of concerns of increased sedation, intranasal esketamine should be administered cautiously in patients receiving other CNS depressants, such as benzodiazepines. In patients with psychosis or a prior history of psychosis, esketamine should be used with increased caution and the risk/benefit ratio should be carefully considered.

Continue to: Because of potential teratogenicity...

Because of potential teratogenicity, esketamine is not recommended in women who are pregnant, may become pregnant, or who are currently nursing.

Intranasal esketamine was examined in a phase III trial of 194 patients age ≥65. At the end of 4 weeks, there was no statistically significant difference in groups on the MADRS, the primary efficacy endpoint. There were no overall differences in the safety profile in patients >65 years compared with younger patients; however, the mean esketamine Cmax and area under the curve were higher in older patients compared with younger adults. The mean esketamine half-life was longer in patients with moderate hepatic impairment.

Abuse liability

Esketamine is a CIII controlled substance and concerns about abuse, misuse, and diversion have been taken into account within the REMS drug safety program.² Patients with a prior history of substance abuse or misuse should be considered with regard to the risk/benefit ratio.

The REMS drug safety program

Due to the nature of its usually transient adverse effects, including sedation, dissociation, hypertension, and nausea, intranasal esketamine will be administered through a REMS drug safety program at certified REMS treatment centers. Certified REMS treatment centers will receive training on how to safely and effectively counsel and monitor patients. Prior to treatment, patients will receive blood pressure monitoring and anticipated adverse effects will be discussed. Patients will be instructed to not eat solid food for 2 hours pre-dose and to not drink anything for 30 minutes prior.

A treatment session consists of nasal administration and a minimum 2-hour post-administration observation period. Blood pressure must be assessed prior to administration and if elevated, (ie, systolic blood pressure >140 mm Hg, diastolic >90 mm Hg), clinicians should consider the risk of short-term increases in blood pressure that may occur. Do not administer if increases in blood pressure or intracranial pressure pose a serious risk.

Continue to: After each intranasal...

After each intranasal administration the patient will be observed for 5 minutes before the second nasal inhaler is utilized and for another 5 minutes when the patient is receiving 84 mg (ie, each inhaler equals 28 mg). After administering, blood pressure should be reassessed at approximately 40 minutes, which corresponds to the Cmax of intranasal esketamine, and periodically thereafter as warranted.

The patient will then be monitored in a quiet environment for a minimum of 2 hours to make sure that dissociative phenomenon, sedation, and hypertensive reactions have normalized prior to discharge from a certified REMS treatment center.

Dosing and administration

Each intranasal device is primed for 2 infusions (1 in each nostril) for a total dose of 28 mg of esketamine. Combinations of devices can be used to adjust the dose as appropriate for individual patients. The recommended starting dose is 56 mg (ie, 2 devices, with a 5-minute gap between devices). The dose can be increased to 84 mg (ie, 3 intranasal devices spaced at 5-minute intervals) by the second dose based on clinical judgment.

The patient will be instructed to recline the head to a 45° angle, clear his or her nostrils prior to the first treatment, and then self-administer a dose to each nostril while holding the reciprocal nostril closed and inhaling. This process is then repeated every 5 minutes for each subsequent device, with a maximum total dose of 3 devices, or 84 mg (Figure 3²). The patient will then be monitored for blood pressure, heart rate, and signs of psychologic or physiologic changes for the next 2 hours. Patients may not drive a car or operate any type of motor equipment until the following day after receiving a normal night’s sleep. Patients will be released from the REMS treatment center after 2 hours if both psychological and physical adverse effects have normalized.

Missed treatment sessions. If a patient misses a treatment session and there is worsening of depressive symptoms, consider returning the patient to the previous dosing schedule (ie, every 2 weeks to once weekly, or weekly to twice weekly).

Continue to: Contraindications for...

Contraindications for intranasal esketamine include:

• aneurysmal vascular disease, including thoracic and abdominal aortic, intracranial, and peripheral arterial vessels, or arterial venous malformations
• history of intracerebral hemorrhage
• hypersensitivity to esketamine, ketamine, or any of the excipients.

Clinical considerations

Intranasal esketamine represents a unique delivery system for the first glutamatergic treatment approved for patients with TRD.

Why Rx? Treatment-resistant depression is found in nearly 1 out of 3 patients with currently available monoaminergic antidepressant treatment options. Patients with TRD are at increased risk of physical and psychological impairment, subsequent worsening of their condition, and social and occupational disability.

Bottom Line

Intranasal esketamine is the first glutamatergic treatment option FDA-approved for patients with treatment-resistant depression who have not responded to standard antidepressant treatment options. In short-term trials, intranasal esketamine significantly improved depressive symptoms as quickly as 24 hours after treatment, with significant improvement maintained through 4 weeks of ongoing administration. In addition, intranasal esketamine was shown to significantly decrease time to relapse for patients who had achieved stable remission or stable response.

Nausea and vomiting. Intranasal esketamine was associated with a 27% rate of nausea at 56 mg, and 32% at 84 mg, with a 6% rate of vomiting at 56 mg and 12% at 84 mg.

Continue to: Pharmacokinetics

Esketamine exposure increases from 28 to 84 mg in a fairly dose-proportional range. No accumulation of esketamine was observed in the plasma following twice-weekly administration. Bioavailability is approximately 48% following nasal administration. The Tmax for esketamine plasma concentration is 20 to 40 minutes after the last nasal spray. Protein binding of esketamine is approximately 43% to 45%. The brain-to-plasma ratio of noresketamine is 4 to 6 times lower than that of esketamine. The half-life of esketamine ranged from 7 to 12 hours. The mean half-life of noresketamine was approximately 8 hours. Esketamine is primarily metabolized to a noresketamine metabolite via cytochrome P450 (CYP) enzymes, 2B6 and 3A4. Noresketamine is metabolized by CYP-dependent pathways and certain metabolites undergo glucuronidation. Drug interaction studies demonstrate that intranasal esketamine had very little effect on pharmacokinetic interactions with other medications.

Potential drug interactions

Central nervous system depressants. Concomitant use of esketamine and other CNS depressants (ie, benzodiazepines, opioids, alcohol) may increase sedation. Patients receiving esketamine with concomitant use of other CNS depressants should be closely monitored for sedation.

Psychostimulants. Concomitant use of esketamine and psychostimulants (ie, amphetamines, methylphenidates, modafinil, and armodafinil) may increase blood pressure. Patients receiving esketamine with concomitant use of psychostimulants should be closely monitored for elevations in blood pressure.

Monoamine oxidase inhibitors. Concomitant use of esketamine with monoamine oxidase inhibitors may increase blood pressure. Closely monitor blood pressure with concomitant use of esketamine and monoamine oxidase inhibitors.

Use in special populations. Because of concerns of increased sedation, intranasal esketamine should be administered cautiously in patients receiving other CNS depressants, such as benzodiazepines. In patients with psychosis or a prior history of psychosis, esketamine should be used with increased caution and the risk/benefit ratio should be carefully considered.

Continue to: Because of potential teratogenicity...

Because of potential teratogenicity, esketamine is not recommended in women who are pregnant, may become pregnant, or who are currently nursing.

Intranasal esketamine was examined in a phase III trial of 194 patients age ≥65. At the end of 4 weeks, there was no statistically significant difference in groups on the MADRS, the primary efficacy endpoint. There were no overall differences in the safety profile in patients >65 years compared with younger patients; however, the mean esketamine Cmax and area under the curve were higher in older patients compared with younger adults. The mean esketamine half-life was longer in patients with moderate hepatic impairment.

Abuse liability

Esketamine is a CIII controlled substance and concerns about abuse, misuse, and diversion have been taken into account within the REMS drug safety program.² Patients with a prior history of substance abuse or misuse should be considered with regard to the risk/benefit ratio.

The REMS drug safety program

Due to the nature of its usually transient adverse effects, including sedation, dissociation, hypertension, and nausea, intranasal esketamine will be administered through a REMS drug safety program at certified REMS treatment centers. Certified REMS treatment centers will receive training on how to safely and effectively counsel and monitor patients. Prior to treatment, patients will receive blood pressure monitoring and anticipated adverse effects will be discussed. Patients will be instructed to not eat solid food for 2 hours pre-dose and to not drink anything for 30 minutes prior.

A treatment session consists of nasal administration and a minimum 2-hour post-administration observation period. Blood pressure must be assessed prior to administration and if elevated, (ie, systolic blood pressure >140 mm Hg, diastolic >90 mm Hg), clinicians should consider the risk of short-term increases in blood pressure that may occur. Do not administer if increases in blood pressure or intracranial pressure pose a serious risk.

Continue to: After each intranasal...

After each intranasal administration the patient will be observed for 5 minutes before the second nasal inhaler is utilized and for another 5 minutes when the patient is receiving 84 mg (ie, each inhaler equals 28 mg). After administering, blood pressure should be reassessed at approximately 40 minutes, which corresponds to the Cmax of intranasal esketamine, and periodically thereafter as warranted.

The patient will then be monitored in a quiet environment for a minimum of 2 hours to make sure that dissociative phenomenon, sedation, and hypertensive reactions have normalized prior to discharge from a certified REMS treatment center.

Dosing and administration

Each intranasal device is primed for 2 infusions (1 in each nostril) for a total dose of 28 mg of esketamine. Combinations of devices can be used to adjust the dose as appropriate for individual patients. The recommended starting dose is 56 mg (ie, 2 devices, with a 5-minute gap between devices). The dose can be increased to 84 mg (ie, 3 intranasal devices spaced at 5-minute intervals) by the second dose based on clinical judgment.

The patient will be instructed to recline the head to a 45° angle, clear his or her nostrils prior to the first treatment, and then self-administer a dose to each nostril while holding the reciprocal nostril closed and inhaling. This process is then repeated every 5 minutes for each subsequent device, with a maximum total dose of 3 devices, or 84 mg (Figure 3²). The patient will then be monitored for blood pressure, heart rate, and signs of psychologic or physiologic changes for the next 2 hours. Patients may not drive a car or operate any type of motor equipment until the following day after receiving a normal night’s sleep. Patients will be released from the REMS treatment center after 2 hours if both psychological and physical adverse effects have normalized.

Missed treatment sessions. If a patient misses a treatment session and there is worsening of depressive symptoms, consider returning the patient to the previous dosing schedule (ie, every 2 weeks to once weekly, or weekly to twice weekly).

Continue to: Contraindications for...

Contraindications for intranasal esketamine include:

• aneurysmal vascular disease, including thoracic and abdominal aortic, intracranial, and peripheral arterial vessels, or arterial venous malformations
• history of intracerebral hemorrhage
• hypersensitivity to esketamine, ketamine, or any of the excipients.

Clinical considerations

Intranasal esketamine represents a unique delivery system for the first glutamatergic treatment approved for patients with TRD.

Why Rx? Treatment-resistant depression is found in nearly 1 out of 3 patients with currently available monoaminergic antidepressant treatment options. Patients with TRD are at increased risk of physical and psychological impairment, subsequent worsening of their condition, and social and occupational disability.

Bottom Line

Intranasal esketamine is the first glutamatergic treatment option FDA-approved for patients with treatment-resistant depression who have not responded to standard antidepressant treatment options. In short-term trials, intranasal esketamine significantly improved depressive symptoms as quickly as 24 hours after treatment, with significant improvement maintained through 4 weeks of ongoing administration. In addition, intranasal esketamine was shown to significantly decrease time to relapse for patients who had achieved stable remission or stable response.

Treatment-resistant depression (TRD) is a common clinical struggle that practicing clinicians address on a daily basis. Major depressive disorder affects nearly 1 in 5 Americans at some point in their life and, by definition, impairs social and occupational functioning. Historic treatments have focused on the monoamine theories of depression—modulating the monoamines serotonin, norepinephrine, and/or dopamine. Limitations of currently available antidepressants include delayed onset of effect and low remission rates. To further complicate the matter, numerous studies have shown that with each subsequent antidepressant trial, patients have a decreasing likelihood of responding to subsequent antidepressant treatment options. For example, in the classic STAR*D trial, by the time a patient had not responded to the first 2 antidepressant options, the chance that they would respond to a third or fourth antidepressant had decreased to approximately 15% per antidepressant treatment course.¹

To address the need for new treatments for patients with TRD, on March 5, 2019 the FDA-approved intranasal esketamine (brand name: Spravato) (Table 1²) following the evaluation of its efficacy through short-term clinical trials and a longer-term maintenance-of-effect trial. Intranasal esketamine is indicated, in conjunction with an oral antidepressant, for adult patients with TRD.² Esketamine is a CIII controlled substance, and concerns about abuse, misuse, and diversion have been taken into account within the Risk Evaluation and Mitigation Strategy (REMS) drug safety program. The agent is only available through a restricted distribution—the REMS will mandate that REMS certified pharmacies dispense directly to a REMS certified treatment program. Intranasal esketamine will not be sampled or dispensed directly to patients.

How it works

Modern research has looked beyond the monoamine system to explore the neuro-modulatory effects of glutamate and gamma-aminobutyric acid (GABA).³ The yin and yang of glutamate and GABA revolves around neural excitation vs neural inhibition at a local synaptic level. The primary effects of the glutamate and GABA systems (Table 2) can be broken down into several key areas of understanding.

Glutamate modulates ionotropic N-methyl-d-aspartate (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, and a family of non-ionic metabotropic receptors, or mGluRs. Glutamate stimulation of NMDA or AMPA receptors increases Ca²⁺ ion influx and enhances neural firing. Conversely, GABA stimulation increases Cl^– ion influx, which inhibits neural firing. Antagonizing glutamate receptors inhibits neural firing. N-methyl-d-aspartate receptors localized on the GABA interneuron modulate GABAergic activity. Antagonism of the NMDA receptor on GABA interneurons decreases GABA activity. Decreased activity of the GABA interneuron promotes intrasynaptic glutamate release and enhances glutamate stimulation of postsynaptic AMPA receptors. Glutamate stimulation of AMPA receptors then stimulates a cascade of intrasynaptic signaling that promotes the release of brain-derived neurotrophic factor (BDNF) and increased production of neuronal membrane proteins with subsequent neural plasticity.

Esketamine, the S-enantiomer of ketamine, has a higher affinity for the NMDA receptor than the R-enantiomer and has been developed as an intranasal adjunctive treatment for TRD. Esketamine blocks NMDA receptors on GABA interneurons. This allows for increased pulsatile release of glutamate into the synapse. Intrasynaptic glutamate then stimulates postsynaptic AMPA receptors. Glutamate stimulation of postsynaptic AMPA receptors results in an intracellular cascade that activates the enzymes tropomyosin receptor kinase B (TrkB) and mammalian target of rapamycin (mTOR). TrkB stimulation results in increased production and release of BDNF. mTor stimulation increases neuronal membrane protein formation with subsequent increased neural plasticity. Taken together, preclinical models show that esketamine’s inhibition of the NMDA receptor on the GABA interneuron results in a cascade of increased BDNF release and synaptogenesis with increased neuroplasticity (Table 3).

Clinical implications

Treatment-resistant depression affects nearly one-third of patients currently receiving standard antidepressant treatment. Major depressive disorder is currently the second leading cause of disability for working adults within the United States and one of the largest causes of disability worldwide. The esketamine nasal spray could be beneficial for patients who have experienced TRD with standard monoamine antidepressants.

Supporting evidence

Clinical trials examining intranasal esketamine include both short- and long-term studies of patients with TRD.

Continue to: Esketamine was evaluated...

Esketamine was evaluated in a randomized, placebo-controlled, double-blind, multicenter, short-term (4-week) phase III study in adult patients age 18 to 65 with TRD (they had not responded to at least 2 different antidepressants of adequate dose and duration).⁴ After discontinuing prior antidepressant treatments, all patients were started on a newly initiated antidepressant and were also randomized to concomitant intranasal esketamine or intranasal placebo as follows:

• 114 patients were randomized to the intranasal esketamine plus newly initiated oral antidepressant arm
• 109 patients were randomized to the placebo nasal spray plus newly initiated oral antidepressant arm
• The mean baseline Montgomery-Åsberg Depression Rating Scale (MADRS) score for each group was 37 (ie, moderately to severely depressed).

Newly started antidepressants included escitalopram, sertraline, duloxetine, or extended-release venlafaxine. Esketamine intranasal spray was initiated at 56 mg and could be titrated up to 84 mg at the second dose, based on investigator discretion. The mean age was 47; 62% of the patients were female, 93% were White, and 5% were black. The newly initiated oral antidepressant was a selective serotonin reuptake inhibitor in 32% of patients and an serotonin-norepinephrine reuptake inhibitor in 68% of patients. The time course of response for this 4-week, short-term treatment study is illustrated in Figure 1.² While the primary efficacy measure was improvement of MADRS score at Week 4, the majority of the placebo-active drug separation occurred 24 hours after the initial 56 mg dose of esketamine. Between 24 hours and Day 28, intranasal esketamine showed continued separation from antidepressant plus placebo nasal spray. Investigators could increase both placebo nasal spray or esketamine, with 67% of patients receiving 84 mg twice weekly at Day 28.

A long-term, double-blind multicenter maintenance-of-effect trial examined adults age 18 to 65 with TRD.^5-6 Patients in this study were responders in 1 of 2 short-term studies or in an open-label direct enrollment study. Stable remission was defined as a MADRS total score <12 for at least 3 of the last 4 weeks of the study, and stable response was defined as a MADRS reduction of >50% but not in remission. After 16 weeks of intranasal esketamine plus an oral antidepressant, stable remitters and stable responders were then randomized separately to continue intranasal esketamine or switch to placebo nasal spray, with both groups continuing on their concomitant oral antidepressant. The primary study endpoint was time to relapse. Relapse was defined as a MADRS total score >22 for more than 2 consecutive weeks, hospitalization for worsening of depression, or any other clinically relevant event. The median age was 48, 66% were female, 90% were White and 4% were black. Patients in stable response or stable remission experienced a significantly longer time to relapse compared with patients who continued their oral antidepressant but were switched to placebo intranasal spray. In this remission response study, patients could receive intranasal treatment weekly or bi-weekly based on symptom severity (Figure 2²).

Impact on driving. Two studies examined the impact of esketamine on driving performance. One examined adults with major depressive disorder and the other examined healthy participants. The effects of a single 84-mg dose of esketamine nasal spray on a patient’s ability to drive was assessed in 23 healthy adults. In this study, mirtazapine was used as an active control. Driving performance was assessed at 8 hours after treatment with esketamine nasal spray or mirtazapine. Driving performance 8 hours after esketamine nasal spray was similar to placebo and active control. Two participants discontinued the driving task after receiving esketamine due to post-dose adverse reactions. One reported pressure behind the eyes and paresthesia of the hands and feet. The other reported headache and light sensitivity with anxiety.

A second study evaluated the effects of repeated esketamine administration on driving performance in 25 adults with major depressive disorder. In this study, an ethanol-containing beverage was used as an active control. After administration of a single 84-mg dose of intranasal esketamine, driving performance was the same as a placebo at 18 hours. In the multiple dose phase, standard driving performance was similar for esketamine nasal spray and placebo at 6 hours postdose on Days 11, 18, and 25.

Continue to: Pharmacologic profile

Adverse events. The most common adverse events in patients treated with esketamine nasal spray were dissociation (41%), dizziness (29%), nausea (28%), sedation (23%), and vertigo (23%).² The majority of these effects were short-term and resolved during the 2-hour observation period.

In addition to spontaneously reported events, sedation and dissociation were further monitored with specific scales. Sedation was measured with the Modified Observer’s Alertness and Sedation Scale. Using this scale, 50% of patients receiving 56 mg and 61% of patients receiving 84 mg of esketamine met criteria for sedation.

Similarly, dissociation/perceptional changes were measured with spontaneously reported events and also with the Clinician Administered Dissociative State Scale. On this scale, 61% of patients receiving the 56-mg dose, and 69% of patients receiving the 84-mg dose met criteria for dissociation/perceptional changes after dose administration.

Increases in blod pressure. Esketamine intranasal spray was associated with a 7 to 9 mm Hg increase in systolic blood pressure and a 4 to 6 mm Hg increase in diastolic blood pressure, both of which peaked 40 minutes post-dose.

Nausea and vomiting. Intranasal esketamine was associated with a 27% rate of nausea at 56 mg, and 32% at 84 mg, with a 6% rate of vomiting at 56 mg and 12% at 84 mg.

“Hi Dr. Burke, thanks for coming in today. My daughter struggles with depression and I feel like every time I try to reach out, I hit a dead end with her. How do I connect with someone, who by the nature of their disease, is hard to reach?”

The answer? I’m not quite sure. I stood in front of a classroom of parents, siblings, and persons struggling with mental health issues, lecturing about depression. I can tell you about the complex interplay of biologic, psychological, and social factors that can lead one to become depressed. I can tell you the prevalence of depression in today’s society, and how it is rising among all age groups. I can tell you a myriad of different treatments, from pharmacologic to therapeutic to procedural, for depression. But how, from a parent’s perspective, can you connect with your child struggling with depression when they do not want your help? That I cannot tell you, at least not yet, anyways.

I had connected with the National Alliance on Mental Illness (NAMI) in the Fall of 2018, when a patient of mine was discharged from hospitalization and told by a faith-based substance use treatment program that he would not be allowed to use any “mind-altering” medications when he returned to their program. Concerned about my patient, whom I had just stabilized with the use of medications, I did my best to work through that organization’s resistance to psychotropic medications. When that failed, I reached out to NAMI for help in advocating for persons with mental illness. My involvement escalated to giving a lecture on “Living with Depression” to our local chapter of approximately 25 individuals that night. I had expected to lecture to an engaged crowd about what I thought was my immense knowledge of depression, from diagnosis to development to treatment. What I had not expected, however, was to have a learning experience of my own.

I stood at the front of the room, listening to story after story of persons with depression and their family members discussing their experiences. Throughout the 90-minute lecture, my emotions ranged from being impressed to shocked, scared, and, ultimately, proud. For the past year and 7 months, I had been spending time with persons with mental illness on what was likely the worst days of their lives. I had seen a variety of severe presentations, from grossly psychotic to acutely manic to majorly depressed to highly agitated. With that wealth of experience, I had thought I was becoming an expert; however, at the front of that classroom that night, I realized how little I actually knew. Yes, I had contemplated before how much severe mental illness and hospitalization could affect a person and their loved ones. However, it was a different level of understanding to hear first-hand accounts of the loss of relationships, the struggle to connect, and the fall-out from intensive inpatient treatment.

In residency, we spend what seems like an immeasurable amount of time on inpatient psychiatric units, in outpatient clinics, and everywhere in between. We see so many patients on a daily, weekly, monthly, and yearly basis that it becomes easy to lose the individuality of each patient. We start associating patients with their disorder, rather than with who they are. However, if we take a step back and allow a larger perspective—one that considers not only the patient but their families and communities—we likely would be able to provide greater and more comprehensive care.

My experience at NAMI was one that I will treasure forever. It opened my eyes to struggles that had I failed to even notice, and for that, and many other connections I made, I am grateful to have been blessed with this experience. My greatest recommendation to my fellow residents would be to engage with your local community organizations in the hope that you, too, can have an eye-opening experience that will strengthen your practice.

I had connected with the National Alliance on Mental Illness (NAMI) in the Fall of 2018, when a patient of mine was discharged from hospitalization and told by a faith-based substance use treatment program that he would not be allowed to use any “mind-altering” medications when he returned to their program. Concerned about my patient, whom I had just stabilized with the use of medications, I did my best to work through that organization’s resistance to psychotropic medications. When that failed, I reached out to NAMI for help in advocating for persons with mental illness. My involvement escalated to giving a lecture on “Living with Depression” to our local chapter of approximately 25 individuals that night. I had expected to lecture to an engaged crowd about what I thought was my immense knowledge of depression, from diagnosis to development to treatment. What I had not expected, however, was to have a learning experience of my own.

I stood at the front of the room, listening to story after story of persons with depression and their family members discussing their experiences. Throughout the 90-minute lecture, my emotions ranged from being impressed to shocked, scared, and, ultimately, proud. For the past year and 7 months, I had been spending time with persons with mental illness on what was likely the worst days of their lives. I had seen a variety of severe presentations, from grossly psychotic to acutely manic to majorly depressed to highly agitated. With that wealth of experience, I had thought I was becoming an expert; however, at the front of that classroom that night, I realized how little I actually knew. Yes, I had contemplated before how much severe mental illness and hospitalization could affect a person and their loved ones. However, it was a different level of understanding to hear first-hand accounts of the loss of relationships, the struggle to connect, and the fall-out from intensive inpatient treatment.

In residency, we spend what seems like an immeasurable amount of time on inpatient psychiatric units, in outpatient clinics, and everywhere in between. We see so many patients on a daily, weekly, monthly, and yearly basis that it becomes easy to lose the individuality of each patient. We start associating patients with their disorder, rather than with who they are. However, if we take a step back and allow a larger perspective—one that considers not only the patient but their families and communities—we likely would be able to provide greater and more comprehensive care.

My experience at NAMI was one that I will treasure forever. It opened my eyes to struggles that had I failed to even notice, and for that, and many other connections I made, I am grateful to have been blessed with this experience. My greatest recommendation to my fellow residents would be to engage with your local community organizations in the hope that you, too, can have an eye-opening experience that will strengthen your practice.

Two patients were admitted to our unit at the same time: Mr. P, age 27, an architect with unspecified personality disorder, and Mr. D, age 62, a bank manager who has had bipolar disorder for 40 years and was experiencing a moderate depressive episode. Mr. P’s discomfort with the treatment team informing him of his treatment plan was evident, and he discussed at length his terms and stipulations for management. Mr. D, on the other hand, was loath to shoulder the burden of any decision-making, even in minor matters such as what time he should take his daily walk.

Patient autonomy is a central factor in the present-day doctor–patient equation. In psychiatry, this is sometimes further complicated by a patient’s impaired judgment and lowered decision-making capacity (DMC). In our clinical practice, we often notice that younger patients (ie, millennials) prefer to have autonomy rather than being given instructions, which they may find patronizing, whereas the older generation relies more on the doctor for decision-making.

What the decision-making process entails

The decision-making process involves 3 steps:

• information gathering
• deliberation
• implementation.

Decision-making preferences fall on a spectrum that ranges from paternalism at one end to autonomy on the other, with many intervening components, characterized by varying amounts of responsibility shared between doctor and patient.¹ This typically comes into play when there is more than one treatment option with similar outcomes.² Paternalism is defined as an action performed with the intent of promoting another’s good but occurring against the other’s will, or without consent.³ Here, the patient is not privy to the deliberation process, and no explanations are provided.¹Hard paternalism focuses on doing good for the patient rather than respecting his or her decision-making, whereas soft paternalism implies trying to raise one final red flag, but ultimately not standing in the way of the patient’s choice.⁴

Two other decision-making constructs are shared decision-making (SDM) and informed decision-making (IDM). In SDM, the deliberation process involves participation of both patient and doctor, with active discussion and a final decision after both parties reach an agreement. In IDM, the deliberation is conducted solely by the patient, after he or she receives all information. Shared decision-making and IDM are frequently used interchangeably, but in the latter, the doctor has no role other than to provide information.^1,5

Before choosing SDM or IDM, it is necessary to assess the patient’s DMC—the ability to understand information about choices, make a judgment that respects personal values, understand potential outcomes, and freely communicate his or her wishes.⁶

Benefits and risks

The progression from paternalism to autonomy began in the mid-20th century as a consequence of the Nuremberg Trials, from which the concept of “informed consent” first came into existence.⁷ The Indian value system has always regarded the medical profession and its practitioners with high esteem, as evidenced by the Sanskrit quote “Vaidyo Narayano Harihi,” which translates to “The doctor is God.” A significant chunk of the Indian population still considers the doctor’s word to be law, and they hand over health-related decisions to medical professionals. Here, the expectation of a paternalistic attitude is decidedly unequivocal.

Of course, there are pros and cons to every approach. Making patients’ independence a priority is the highest virtue of autonomy, but in such cases a patient may have difficulty comprehending medical consequences, and therefore may miss out on the benefits of a sound professional perspective. Paternalism may be superior medically, but the doctor may not be aware of all patient-specific factors, and it would not be prudent to make a decision for a patient without being privy to the entire picture.

The 21st century has witnessed a change in attitudes regarding medical care. With an increasing interest in patient autonomy, it is time for us to adopt these changes and move towards the patient-centred end of the spectrum. However, this should occur only after the patient improves enough symptomatically to regain DMC; autonomy is unlikely to be appropriate for patients with serious mental illness. Ideally, SDM includes the best of both worlds, and results in optimal outcomes. However, when SDM breaks down, a selective, soft paternalistic attitude would be most beneficial, without impinging on the patient’s basic personal rights.
