NEW ORLEANS – Protein profiling of cerebrospinal fluid and MRI has revealed the involvement of exacerbated gray matter demyelination and brain atrophy in the progression of multiple sclerosis.

The pattern of the cerebrospinal fluid (CSF) biomarkers, which correspond to the extent of gray matter damage, have potential value in stratifying patients in terms of disease severity from the onset of multiple sclerosis (MS), Roberta Magliozzi, Ph.D., of the University of Verona (Italy) said at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

Gray matter atrophy and the accumulation of cortical lesions are central to the progressive clinical deterioration that occurs in MS. The damage involves a “compartmentalized immune response” featuring meningeal infiltration of certain immune cells, which is associated with increased cortical demyelination and meningeal inflammation. The gray matter damage and inflammation are harbingers of earlier onset and rapid progression of neurological damage in MS, and a more severe disease outcome.

“We sought to find a combination of CSF biomarkers [and] neuropathological and early neuroimaging correlates of disease progression in order to predict onset and rate of MS progression,” Dr. Magliozzi explained.

The investigators assessed gray matter damage with MRI and analyzed CSF proteins in 36 MS patients and 12 healthy controls and also acquired and analyzed meningeal and CSF samples after death from 20 individuals with secondary progressive MS (SPMS) and 10 healthy individuals to detect inflammatory mediators associated with meningeal infiltration that were released to the CSF.

MS patients with meningeal infiltration displayed more extensive gray matter demyelination and more rapid disease progression. They also demonstrated a “pronounced proinflammatory CSF profile” featuring overexpression of an array of molecules associated with chronic inflammation. Patients with less gray matter damage displayed a pattern of increased regulatory molecules. Consistent with the patient data, similar expression patterns were evident in the meninges and CSF samples of postmortem SPMS cases with a higher level of meningeal inflammation and gray matter demyelination.

“Meningeal infiltrates may represent the main source of intrathecal inflammatory activity mediating the gradient of cortical tissue injury since early disease stages and in progressive MS,” Dr. Magliozzi said.

The markedly different CSF profiles in patients with more and less extensive gray matter damage may be an exploitable characteristic to stratify patients early in the course of MS, with benefits in disease prognosis and monitoring, and treatment that is more rationally geared to the patient’s condition.

“The results indicate that we may be able to get an image-based functional profile of patients in relapse, which would be a phenomenal finding,” Dr. Jerry Wolinsky of the University of Texas Health Science Center at Houston, commented in a press conference following the presentation.

The study was funded by Progressive MS Alliance. Dr. Magliozzi had no disclosures.

Initiation has been a part of the tradition of many sororities, fraternities, sports teams, and other organizations to screen and evaluate potential members. Initiation activities can range from humorous, such as pulling pranks on others, to more serious, such as being able to recite the organization’s rules and creed. It is used in the hopes of increasing a new member’s commitment to the group, with the goal of creating group cohesion.

Hazing is not initiation

Hazing is the use of ritualized physical, sexual, and psychological abuse in the guise of initiation. Hazing activities do not help identify the qualities that a person needs for group membership, and can lead to severe physical and psychological harm. Many hazing rituals are done behind closed doors, some with a vow of secrecy.

Studies indicate that 47% of students have been hazed before college, and that 3 of every 5 college students have been subjected to hazing.¹ Military and sports teams also have a high rate of hazing; 40% of athletes report that a coach or advisor knew about the hazing.²

Dangers of hazing

Victims of hazing might be brought to the emergency room with severe injury, including broken bones, burns, alcohol intoxication–related injury, chest trauma, multi-organ system failure, sexual trauma, and other medical emergencies, or could die from injuries sustained during hazing activities.

In the 44 states where hazing is illegal, hazing participants could be held be civilly and criminally liable for their actions. Hazing victims may be required to commit crimes, ranging from destruction of property to kidnapping. One-half of all hazing activities involve the use of alcohol,² and 82% of hazing-related deaths involve alcohol.¹

What is your role in treating hazing victims?

You might be called on to treat the psychological symptoms of hazing, including:

• depression
• anxiety
• acute stress syndrome
• alcohol- and drug-related delirium
• posttraumatic stress syndrome.

In addition, you might find yourself needing to:

Arrange for medical care immediately if the patient has a medical problem or an injury.

Contact a victim advocacy programif the victim has made allegations about, or there is evidence of, sexual assault, rape, other sexual injury, or physical or psychological violence.

Notify appropriate law enforcement personnel.

Notify the leadership of the organization (eg, team, school, club) within which the hazing occurred.

Perform a psychiatric assessment and provide treatment for the victim. Some symptoms seen in victims of hazing include sleep disturbance and insomnia, poor grades, eating disorders, depression, anxiety, feelings of low self-esteem and self-worth, trust issues, and symptoms commonly seen in patients with posttraumatic stress syndrome. Symptoms sometimes appear immediately after a hazing event; other times, they develop weeks later. Supportive counseling, stabilization, and advocacy are the immediate goals.

Provide education and treatment for the perpetrator. Unlike bullying, most hazing is not instituted to harm the victim but is seen as a tradition and ritual to increase commitment and bonding. The perpetrator might feel surprise and guilt as to the harm that was done to the victim. Observers of hazing rituals might be traumatized by viewing participants humiliated or abused, and both observers and perpetrators as participants may face legal consequences. Counseling and group debriefing provide education and help them cope with these issues.

Act as a consultant to schools, teams, and other organizations to ensure that group cohesion and team building is obtained in a way that benefits the group and does not harm a member or the organization.

Psychiatrists can provide literature and information especially to adolescent and young adult patients who are at highest risk of hazing. Handouts, informational brochures and posters and be placed in the waiting areas for patient to view. These can be found online (such as www.doe.in.gov/sites/default/files/safety/and-hazing.pdf) or obtained from local colleges and school systems.

Life expectancy for both males and females has been increasing over the past several decades to an average of 76 years. However, the life expectancy among individuals with schizophrenia in the United States is 61 years—a 20% reduction.¹ Patients with schizophrenia are known to be at increased risk of several comorbid medical conditions, such as type 2 diabetes mellitus (T2DM), coronary artery disease, and digestive and liver disorders, compared with healthy people (Figure, page 32).^2-5 This risk may be heightened by several factors, including sedentary lifestyle, a high rate of cigarette use, poor self-management skills, homelessness, and poor diet. 

Although substantial attention is paid to the psychiatric and behavioral management of schizophrenia, many barriers impede the detection and treatment of patients’ medical conditions, which have been implicated in excess unforeseen deaths. Patients with schizophrenia might experience delays in diagnosis, leading to more acute comorbidity at time of diagnosis and premature mortality

Cardiovascular disease is the leading cause of death among psychiatric patients.⁶ Key risk factors for cardiovascular disease include smoking, obesity, hypertension, dyslipidemia, diabetes, and lack of physical activity, all of which are more prevalent among patients with schizophrenia.⁷ In addition, antipsychotics are associated with adverse metabolic effects.⁸ In general, smoking and obesity are the most modifiable and preventable risk factors for many medical conditions, such as cardiovascular disease, hyperlipidemia, diabetes, and many forms of cancer (Table 1).

In this article, we discuss how to manage common medical comorbidities in patients with schizophrenia. Comprehensive management for all these medical conditions in this population is beyond the scope of this article; we limit ourselves to discussing (1) how common these conditions are in patients with schizophrenia compared with the general population and (2) what can be done in psychiatric practice to manage these medical comorbidities (Box).

Obesity
Obesity—defined as body mass index (BMI) of >30—is common among patients with schizophrenia. The condition leads to poor self-image, decreased treatment adherence, and an increased risk of many chronic medical conditions (Table 1). Being overweight or obese can increase stigma and social discrimination, which will undermine self-esteem and, in turn, affect adherence with medications, leading to relapse.

The prevalence of obesity among patients with schizophrenia is almost double that of the general population⁹ (Figure^2-5). Several factors predispose these patients to overweight or obese, including sedentary lifestyle, lack of exercise, a high-fat diet, medications side effects, and genetic factors. Recent studies report the incidence of weight gain among patients treated with antipsychotics is as high as 80%¹⁰ (Table 2).

Mechanisms involved in antipsychotic-induced weight gain are not completely understood, but antagonism of serotonergic (5-HT2C, 5-HT1A), histamine (H1), dopamine (D2), muscarinic, and other receptors are involved in modulation of food intake. Decreased energy expenditure also has been blamed for antipsychotic-induced weight gain.¹⁰

Pharmacotherapy and bariatric surgery can be as effective among patients with schizophrenia as they are among the general population. Maintaining a BMI of <25 kg/m² lowers the risk of cardiovascular disease by 35% to 55%.⁶ Metformin has modest potential for offsetting weight gain and providing some metabolic control in overweight outpatients with schizophrenia,¹¹ and should be considered early when treating at-risk patients.

Managing obesity. Clinicians can apply several measures to manage obesity in a patient with schizophrenia:

• Educate the patient, and the family, about the risks of being overweight or obese.
• Monitor weight and BMI at each visit.
• Advise smoking cessation.
• When clinically appropriate, switch to an antipsychotic with a lower risk of weight gain—eg, from olanzapine or high-dose quetiapine to a high- or medium-potency typical antipsychotic (eg, haloperidol, perphenazine), ziprasidone, aripiprazole, iloperidone, and lurasidone (Table 2, page 36).
• Consider prophylactic use of metformin with an antipsychotic; the drug has modest potential for offsetting weight gain and providing better metabolic control in an overweight patient with schizophrenia.¹¹
• Encourage the patient to engage in modest physical activity; for example, a 20-minute walk, every day, reduces the risk of cardiovascular disease by 35% to 55%.⁶
• Recommend a formal lifestyle modification program, such as behavioral group-based treatment for weight reduction.¹²
• Refer the patient and family to a dietitian.

Type 2 diabetes mellitus
There is strong association between T2DM and schizophrenia that is related to abnormal glucose regulation independent of any adverse medication effect.¹³ Ryan et al¹⁴ reported that first-episode, drug-naïve patients with schizophrenia had a higher level of intra-abdominal fat than age- and BMI-matched healthy controls, suggesting that schizophrenia could be associated with changes in adiposity that might increase the risk of insulin resistance, hyperlipidemia, and dyslipidemia. Mechanisms that increase the risk of T2DM in schizophrenia include genetic and environmental factors, such as family history, lack of physical activity, and poor diet.

Diagnosis. All patients with schizophrenia should be evaluated for undiagnosed diabetes. The diagnosis of T2DM is made by documenting:

• a fasting plasma glucose reading of ≥126 mg/dL
• symptoms of T2DM, along with a random plasma glucose reading of ≥200 mg/dL
• 2-hour reading of a plasma glucose level >200 mg/dL on an oral glucose tolerance test.

Recent guidelines also suggest using a hemoglobin A_1c value cutoff of ≥6.5% to diagnose T2DM.

In the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study, 38% of patients with schizophrenia and diabetes were not receiving any treatment for T2DM.¹⁵

Risk factors for T2DM are:

• BMI >25
• a first-degree relative with diabetes
• lack of physical activity
• being a member of a high-risk ethnic group (African American, Hispanic American, Native American, Asian American, or Pacific Islander)
• having delivered a baby >9 lb or having had gestational diabetes
• hypertension
• high-density lipoprotein (HDL) cholesterol level of ≤35 mg/dL
• triglyceride level of ≥250 mg/dL
• history of an abnormal glucose tolerance test
• history of abnormal findings on a fasting plasma glucose test
• history of vascular disease.

Early detection and management.

• Educate the patient and family about signs and symptoms of T2DM, such as polyuria, nocturia, polydipsia, fatigue, visual disturbances, and (in women) vulvitis. Also, psychiatrists should be aware of, and inquire about, symptoms of diabetic ketoacidosis.
• At the start of therapy with any antipsychotic, particularly a second-generation antipsychotic (SGA), ask patients about a family history of diabetes and measure the hemoglobin A_1c value.
• Monitor the hemoglobin A_1c level 4 months after starting an antipsychotic, then annually, in a patient with significant risk factors for diabetes.
• Monitor blood glucose every 6 months in patients with no change from initial results and more frequently in those with significant risk factors for diabetes and those who gain weight.
• Order a lipid panel and measure the serum glucose level to rule out dyslipidemia and diabetes, because a patient with high lipid levels and diabetes is at higher risk of developing cardiovascular conditions.
• Advocate for smoking cessation.
• Switch to an antipsychotic with a lower risk of diabetes when clinically appropriate, such as switching a patient from olanzapine or high-dose quetiapine to a high- or medium-potency typical antipsychotic (such as haloperidol or perphenazine), ziprasidone, aripiprazole, iloperidone, and lurasidone (Table 2).
• Consider prophylactic use of metformin along with antipsychotics. Metformin has been used to improve insulin sensitivity and can lead to weight loss in diabetic and non-diabetic patients. The drug has modest potential for offsetting weight gain and providing better metabolic control in overweight outpatients with schizophrenia.¹¹ Metformin is simple to use, does not lead to hypoglycemia, does not require serum glucose monitoring, and has a favorable safety profile.¹¹
• Educate the patient about modest physical activity. For example, a 20-minute walk every day reduces the risk of cardiovascular disease by 35% to 55%.⁶
• Refer the patient to a dietitian to develop an appropriate diet plan.
• When diabetes is diagnosed, ensure appropriate follow-up and initiation or continuation of therapy with a general practitioner or an endocrinologist.
• Reinforce the need for ongoing follow-up and compliance with therapy for diabetes.

Hyperlipidemia and dyslipidemia
Elevated cholesterol and triglyceride levels are associated with cardiovascular diseases, such as ischemic heart disease and myocardial infarction. A 10% increase in cholesterol levels is associated with a 20% to 30% increase in the risk of coronary artery disease; lowering cholesterol by 10% decreases the risk by 20% to 30%.¹⁶ Triglyceride levels ≥250 mg/dL are associated with 2-fold higher risk of cardiovascular disease.¹⁶

The incidence of dyslipidemia is not as well studied as diabetes in patients with schizophrenia. There is increased prevalence of dyslipidemia in patients with schizophrenia compared with the general population because of obesity, lack of physical activity, and poor dietary habits.¹⁶

Data regarding the effects of first-generation antipsychotics (FGAs) on lipid levels are limited, but high-potency drugs, such as haloperidol, seem to carry a lower risk of hyperlipidemia than low-potency drugs, such as chlorpromazine and thioridazine.¹⁷ A comprehensive review on the effects of SGAs on plasma lipid levels suggested that clozapine, olanzapine, and quetiapine are associated with a higher risk of dyslipidemia¹⁷ (Table 2).

In the CATIE study, olanzapine and clozapine were associated with a greater increase in the serum level of cholesterol and triglycerides compared with other antipsychotics, even after adjusting for treatment duration. Furthermore, a retrospective chart review of patients who switched to aripiprazole from other SGAs showed a decrease in levels of total cholesterol and low-density lipoprotein cholesterol¹⁵ (Table 2).

Patients with schizophrenia are more likely to have dyslipidemia go undiagnosed, and therefore are less likely to be treated for the disorder. In the CATIE study, 88% of patients with dyslipidemia were not receiving any treatment.¹⁵

Management for dyslipidemia.

• Educate the patient and family about risks involved with dyslipidemia.
• Monitor weight and BMI at each visit.
• Monitor lipids to rule out dyslipidemia. Obtain a pretreatment fasting or random lipid profile for any patient receiving an antipsychotic; repeat at least every 6 months after starting the antipsychotic.
• Counsel the patient to quit smoking.
• Switch to an antipsychotic with lower risk of weight gain and dyslipidemia, such as switching from olanzapine or high-dose quetiapine to high- or medium-potency typical antipsychotics (such as, haloperidol or perphenazine), ziprasidone, aripiprazole, iloperidone, and lurasidone (Table 2).
• Educate and encourage the patient about modest physical activity. For example, a 20-minute walk everyday will reduce cardiovascular disease risk by 35% to 55%.⁶
• Refer to a dietitian if indicated.
• Ensure follow-up and initiation of treatment with a general practitioner.
• Educate and encourage the patient about modest physical activity. For example, a 20-minute walk everyday will reduce cardiovascular disease risk by 35% to 55%.

Metabolic syndrome
Metabolic syndrome is cluster of cardiovascular risk factors, including central adiposity, hyperglycemia, dyslipidemia, and hypertension. The National Cholesterol Education Program’s Adult Treatment Panel III report defines metabolic syndrome as the presence of 3 of 5 of the following factors:

• abdominal obesity (waist circumference of >40 inches in men, or >35 inches in women)
• triglyceride level, >150 mg/dL
• HDL cholesterol, <40 mg/dL in men and <50 mg/dL in women
• blood pressure, >130/85 mm Hg
• fasting plasma glucose level, >110 mg/dL.

The presence of metabolic syndrome in the general population is a strong predictor of cardiovascular diseases and diabetes.¹⁸ The adverse effects of metabolic syndrome are thought to relate to atherogenic dyslipidemia, higher blood pressure, insulin resistance with or without glucose intolerance, a proinflammatory state, and a prothrombotic state.

The prevalence of metabolic syndrome in patients with schizophrenia is 2- to 3-fold higher than the general population.¹⁹ In the CATIE study, approximately one-third of patients met criteria for metabolic syndrome at baseline.¹⁵ In a prospective study, De Hert et al²⁰ reported that patients who were started on a SGA had more than twice the rate of developing metabolic syndrome compared with those treated with a FGA (Table 2). Other possible causes of metabolic syndrome are visceral adiposity and insulin resistance.¹⁶Management of the metabolic syndrome involves addressing the individual components that have been described in the preceding sections on T2DM and dyslipidemia.

Hepatitis C
Hepatitis C virus (HCV) infection is thought to be the most common blood-borne illness, with an estimated prevalence of 1% of the U.S. population. Some studies suggest that as many as 16% of people with schizophrenia have HCV infection.⁴ Risk factors for HCV infection include unsafe sexual practices, prostitution, homosexuality, homelessness, and IV drug use.

HCV treatments typically have involved regimens with interferon alfa, which is associated with significant neuropsychiatric side effects, including depression and suicide. There is a dearth of research on treatment of HCV in patients with schizophrenia; however, at least 1 study suggests that there was no increase in psychiatric symptoms in patients treated with interferon-containing regimens.²¹ There is even less evidence to guide the use of newer, non-interferon–based HCV treatment regimens that are better tolerated and have a higher response rate in the general population; there is reason, however, to be hopeful about their potential in patients with schizophrenia and HCV infection.

Managing HCV infection.

• Educate the patients and family about risk factors associated with contracting HCV.
• Screen for HCV infection in patients with schizophrenia because there is higher prevalence of HCV in these patients compared with the general population.
• When HCV infection is diagnosed, educate the patients and family about available treatments.
• Facilitate referral to an HCV specialist for appropriate treatment.

HIV/AIDS
HIV infection is highly prevalent among people suffering from severe mental illness such as schizophrenia. The incidence of HIV/AIDS in patients with schizophrenia is estimated to be 4% to 23%, compared with 0.6% in the general population.²² Risk factors associated with a higher incidence of HIV/AIDS in patients with schizophrenia are lack of knowledge about contracting HIV, unsafe sexual practices, prostitution, homosexuality, homelessness, and IV drug use.²²

Managing HIV/AIDS.

• Educate the patient and family about risk factors associated with contracting HIV/AIDS.
• Educate patients about safe sex practices.
• All patients with schizophrenia should be screened for HIV because there is 10-fold higher HIV prevalence in schizophrenia compared with the general population.
• When HIV infection is diagnosed, facilitate referral to a HIV or infectious disease specialist for treatment.
• Educate the patient in whom HIV/AIDS has been diagnosed about the importance of (1) adherence to his (her) HIV medication regimen and (2) follow-up visits with an infectious disease practitioner and appropriate laboratory tests.
• Educate the patient’s family and significant other about the illness.
• Screen for and treat substance use.
• At each visit, inquire about the patient’s adherence to HIV medical therapy, viral load, and CD4 cell count.

Chronic obstructive pulmonary disease
Patients with schizophrenia are more likely to suffer from respiratory disease, such as chronic obstructive pulmonary disease (COPD) and asthma, compared with the general population.²³ Smoking is a major risk factor for COPD. In a study by Dickerson et al,²⁴ 64% of people with schizophrenia were current smokers, compared with 19% of those without mental illness.

A high rate of smoking rate among people with schizophrenia suggests a “self-medication” hypothesis: That is, stimulation of CNS nicotinic cholinergic receptors treats the negative symptoms of schizophrenia and overcomes the dopamine blocking effects of antipsychotics.²⁵ Among SGAs, only clozapine has a substantial body of evidence to support its association with decreased smoking behavior.

Managing COPD.

• Educate the patient and family about risk factors associated with COPD and smoking.
• Screen for tobacco use at each visit; try to increase motivation to quit smoking.
• Educate the patients and family about the value and availability of smoking cessation programs.
• Prescribe medication to help with smoking cessation when needed. Bupropion and varenicline have been shown to be effective in patients with schizophrenia; nicotine replacement therapies are safe and can be helpful.
• When treating a patient who is in the process of quitting, encourage and help him to maintain his commitment and enlist support from his family.
• Refer to an appropriate medical provider (primary care provider or pulmonologist) for a patient with an established or suspected diagnosis of COPD.

Cancer
Since 1909, when the Board of Control of the Commissioners in Lunacy for England and Wales noted the possibility of a decreased incidence in cancer among psychiatric patients, this connection has been a matter of controversy.²⁶ Subsequent research has been equivocal; the prevalence of cancer has been reported to be either increased, similar, or decreased compared with the general population.^26-28 Risk factors for cancer, including smoking, obesity, poor diet, sedentary lifestyle, and hyperprolactinemia, are more common among patients with schizophrenia.

Genetic factors and a possible protective effect from antipsychotics have been cited as potential causes of decreased prevalence. Clozapine is associated with an increased risk of leukemia. No conclusion can be drawn about the overall prevalence of cancer in schizophrenia.

Managing cancer in a patient with schizophrenia, however, poses a significant challenge²⁹; he might lack capacity to make decisions about cancer treatment. The patient—or his surrogate decision-makers—need to carefully weigh current quality of life against potential benefits of treatment and risks of side effects. Adherence to complex, often toxic, therapies can be challenging for the patient with psychosis. Successful cancer treatment often requires close collaboration between the cancer treatment team and the patient’s support system, including the treating psychiatrist and case management teams.

Bottom Line
Patients with schizophrenia are at higher risk of developing comorbid medical
conditions because of the illness itself, lifestyle behaviors, genetics, and adverse
effects of medications. Because mental health clinicians focus attention on the
psychiatric and behavioral aspect of treatment, often there is delay in screening,
detecting, and treating medical comorbidities. This screening can be done in any
psychiatric practice, which can lead to timely management for those conditions
and preventing premature mortality in patients with schizophrenia.

Life expectancy for both males and females has been increasing over the past several decades to an average of 76 years. However, the life expectancy among individuals with schizophrenia in the United States is 61 years—a 20% reduction.¹ Patients with schizophrenia are known to be at increased risk of several comorbid medical conditions, such as type 2 diabetes mellitus (T2DM), coronary artery disease, and digestive and liver disorders, compared with healthy people (Figure, page 32).^2-5 This risk may be heightened by several factors, including sedentary lifestyle, a high rate of cigarette use, poor self-management skills, homelessness, and poor diet. 

Although substantial attention is paid to the psychiatric and behavioral management of schizophrenia, many barriers impede the detection and treatment of patients’ medical conditions, which have been implicated in excess unforeseen deaths. Patients with schizophrenia might experience delays in diagnosis, leading to more acute comorbidity at time of diagnosis and premature mortality

Cardiovascular disease is the leading cause of death among psychiatric patients.⁶ Key risk factors for cardiovascular disease include smoking, obesity, hypertension, dyslipidemia, diabetes, and lack of physical activity, all of which are more prevalent among patients with schizophrenia.⁷ In addition, antipsychotics are associated with adverse metabolic effects.⁸ In general, smoking and obesity are the most modifiable and preventable risk factors for many medical conditions, such as cardiovascular disease, hyperlipidemia, diabetes, and many forms of cancer (Table 1).

In this article, we discuss how to manage common medical comorbidities in patients with schizophrenia. Comprehensive management for all these medical conditions in this population is beyond the scope of this article; we limit ourselves to discussing (1) how common these conditions are in patients with schizophrenia compared with the general population and (2) what can be done in psychiatric practice to manage these medical comorbidities (Box).

Obesity
Obesity—defined as body mass index (BMI) of >30—is common among patients with schizophrenia. The condition leads to poor self-image, decreased treatment adherence, and an increased risk of many chronic medical conditions (Table 1). Being overweight or obese can increase stigma and social discrimination, which will undermine self-esteem and, in turn, affect adherence with medications, leading to relapse.

The prevalence of obesity among patients with schizophrenia is almost double that of the general population⁹ (Figure^2-5). Several factors predispose these patients to overweight or obese, including sedentary lifestyle, lack of exercise, a high-fat diet, medications side effects, and genetic factors. Recent studies report the incidence of weight gain among patients treated with antipsychotics is as high as 80%¹⁰ (Table 2).

Mechanisms involved in antipsychotic-induced weight gain are not completely understood, but antagonism of serotonergic (5-HT2C, 5-HT1A), histamine (H1), dopamine (D2), muscarinic, and other receptors are involved in modulation of food intake. Decreased energy expenditure also has been blamed for antipsychotic-induced weight gain.¹⁰

Pharmacotherapy and bariatric surgery can be as effective among patients with schizophrenia as they are among the general population. Maintaining a BMI of <25 kg/m² lowers the risk of cardiovascular disease by 35% to 55%.⁶ Metformin has modest potential for offsetting weight gain and providing some metabolic control in overweight outpatients with schizophrenia,¹¹ and should be considered early when treating at-risk patients.

Managing obesity. Clinicians can apply several measures to manage obesity in a patient with schizophrenia:

• Educate the patient, and the family, about the risks of being overweight or obese.
• Monitor weight and BMI at each visit.
• Advise smoking cessation.
• When clinically appropriate, switch to an antipsychotic with a lower risk of weight gain—eg, from olanzapine or high-dose quetiapine to a high- or medium-potency typical antipsychotic (eg, haloperidol, perphenazine), ziprasidone, aripiprazole, iloperidone, and lurasidone (Table 2, page 36).
• Consider prophylactic use of metformin with an antipsychotic; the drug has modest potential for offsetting weight gain and providing better metabolic control in an overweight patient with schizophrenia.¹¹
• Encourage the patient to engage in modest physical activity; for example, a 20-minute walk, every day, reduces the risk of cardiovascular disease by 35% to 55%.⁶
• Recommend a formal lifestyle modification program, such as behavioral group-based treatment for weight reduction.¹²
• Refer the patient and family to a dietitian.

Type 2 diabetes mellitus
There is strong association between T2DM and schizophrenia that is related to abnormal glucose regulation independent of any adverse medication effect.¹³ Ryan et al¹⁴ reported that first-episode, drug-naïve patients with schizophrenia had a higher level of intra-abdominal fat than age- and BMI-matched healthy controls, suggesting that schizophrenia could be associated with changes in adiposity that might increase the risk of insulin resistance, hyperlipidemia, and dyslipidemia. Mechanisms that increase the risk of T2DM in schizophrenia include genetic and environmental factors, such as family history, lack of physical activity, and poor diet.

Diagnosis. All patients with schizophrenia should be evaluated for undiagnosed diabetes. The diagnosis of T2DM is made by documenting:

• a fasting plasma glucose reading of ≥126 mg/dL
• symptoms of T2DM, along with a random plasma glucose reading of ≥200 mg/dL
• 2-hour reading of a plasma glucose level >200 mg/dL on an oral glucose tolerance test.

Recent guidelines also suggest using a hemoglobin A_1c value cutoff of ≥6.5% to diagnose T2DM.

In the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study, 38% of patients with schizophrenia and diabetes were not receiving any treatment for T2DM.¹⁵

Risk factors for T2DM are:

• BMI >25
• a first-degree relative with diabetes
• lack of physical activity
• being a member of a high-risk ethnic group (African American, Hispanic American, Native American, Asian American, or Pacific Islander)
• having delivered a baby >9 lb or having had gestational diabetes
• hypertension
• high-density lipoprotein (HDL) cholesterol level of ≤35 mg/dL
• triglyceride level of ≥250 mg/dL
• history of an abnormal glucose tolerance test
• history of abnormal findings on a fasting plasma glucose test
• history of vascular disease.

Early detection and management.

• Educate the patient and family about signs and symptoms of T2DM, such as polyuria, nocturia, polydipsia, fatigue, visual disturbances, and (in women) vulvitis. Also, psychiatrists should be aware of, and inquire about, symptoms of diabetic ketoacidosis.
• At the start of therapy with any antipsychotic, particularly a second-generation antipsychotic (SGA), ask patients about a family history of diabetes and measure the hemoglobin A_1c value.
• Monitor the hemoglobin A_1c level 4 months after starting an antipsychotic, then annually, in a patient with significant risk factors for diabetes.
• Monitor blood glucose every 6 months in patients with no change from initial results and more frequently in those with significant risk factors for diabetes and those who gain weight.
• Order a lipid panel and measure the serum glucose level to rule out dyslipidemia and diabetes, because a patient with high lipid levels and diabetes is at higher risk of developing cardiovascular conditions.
• Advocate for smoking cessation.
• Switch to an antipsychotic with a lower risk of diabetes when clinically appropriate, such as switching a patient from olanzapine or high-dose quetiapine to a high- or medium-potency typical antipsychotic (such as haloperidol or perphenazine), ziprasidone, aripiprazole, iloperidone, and lurasidone (Table 2).
• Consider prophylactic use of metformin along with antipsychotics. Metformin has been used to improve insulin sensitivity and can lead to weight loss in diabetic and non-diabetic patients. The drug has modest potential for offsetting weight gain and providing better metabolic control in overweight outpatients with schizophrenia.¹¹ Metformin is simple to use, does not lead to hypoglycemia, does not require serum glucose monitoring, and has a favorable safety profile.¹¹
• Educate the patient about modest physical activity. For example, a 20-minute walk every day reduces the risk of cardiovascular disease by 35% to 55%.⁶
• Refer the patient to a dietitian to develop an appropriate diet plan.
• When diabetes is diagnosed, ensure appropriate follow-up and initiation or continuation of therapy with a general practitioner or an endocrinologist.
• Reinforce the need for ongoing follow-up and compliance with therapy for diabetes.

Hyperlipidemia and dyslipidemia
Elevated cholesterol and triglyceride levels are associated with cardiovascular diseases, such as ischemic heart disease and myocardial infarction. A 10% increase in cholesterol levels is associated with a 20% to 30% increase in the risk of coronary artery disease; lowering cholesterol by 10% decreases the risk by 20% to 30%.¹⁶ Triglyceride levels ≥250 mg/dL are associated with 2-fold higher risk of cardiovascular disease.¹⁶

The incidence of dyslipidemia is not as well studied as diabetes in patients with schizophrenia. There is increased prevalence of dyslipidemia in patients with schizophrenia compared with the general population because of obesity, lack of physical activity, and poor dietary habits.¹⁶

Data regarding the effects of first-generation antipsychotics (FGAs) on lipid levels are limited, but high-potency drugs, such as haloperidol, seem to carry a lower risk of hyperlipidemia than low-potency drugs, such as chlorpromazine and thioridazine.¹⁷ A comprehensive review on the effects of SGAs on plasma lipid levels suggested that clozapine, olanzapine, and quetiapine are associated with a higher risk of dyslipidemia¹⁷ (Table 2).

In the CATIE study, olanzapine and clozapine were associated with a greater increase in the serum level of cholesterol and triglycerides compared with other antipsychotics, even after adjusting for treatment duration. Furthermore, a retrospective chart review of patients who switched to aripiprazole from other SGAs showed a decrease in levels of total cholesterol and low-density lipoprotein cholesterol¹⁵ (Table 2).

Patients with schizophrenia are more likely to have dyslipidemia go undiagnosed, and therefore are less likely to be treated for the disorder. In the CATIE study, 88% of patients with dyslipidemia were not receiving any treatment.¹⁵

Management for dyslipidemia.

• Educate the patient and family about risks involved with dyslipidemia.
• Monitor weight and BMI at each visit.
• Monitor lipids to rule out dyslipidemia. Obtain a pretreatment fasting or random lipid profile for any patient receiving an antipsychotic; repeat at least every 6 months after starting the antipsychotic.
• Counsel the patient to quit smoking.
• Switch to an antipsychotic with lower risk of weight gain and dyslipidemia, such as switching from olanzapine or high-dose quetiapine to high- or medium-potency typical antipsychotics (such as, haloperidol or perphenazine), ziprasidone, aripiprazole, iloperidone, and lurasidone (Table 2).
• Educate and encourage the patient about modest physical activity. For example, a 20-minute walk everyday will reduce cardiovascular disease risk by 35% to 55%.⁶
• Refer to a dietitian if indicated.
• Ensure follow-up and initiation of treatment with a general practitioner.
• Educate and encourage the patient about modest physical activity. For example, a 20-minute walk everyday will reduce cardiovascular disease risk by 35% to 55%.

Metabolic syndrome
Metabolic syndrome is cluster of cardiovascular risk factors, including central adiposity, hyperglycemia, dyslipidemia, and hypertension. The National Cholesterol Education Program’s Adult Treatment Panel III report defines metabolic syndrome as the presence of 3 of 5 of the following factors:

• abdominal obesity (waist circumference of >40 inches in men, or >35 inches in women)
• triglyceride level, >150 mg/dL
• HDL cholesterol, <40 mg/dL in men and <50 mg/dL in women
• blood pressure, >130/85 mm Hg
• fasting plasma glucose level, >110 mg/dL.

The presence of metabolic syndrome in the general population is a strong predictor of cardiovascular diseases and diabetes.¹⁸ The adverse effects of metabolic syndrome are thought to relate to atherogenic dyslipidemia, higher blood pressure, insulin resistance with or without glucose intolerance, a proinflammatory state, and a prothrombotic state.

The prevalence of metabolic syndrome in patients with schizophrenia is 2- to 3-fold higher than the general population.¹⁹ In the CATIE study, approximately one-third of patients met criteria for metabolic syndrome at baseline.¹⁵ In a prospective study, De Hert et al²⁰ reported that patients who were started on a SGA had more than twice the rate of developing metabolic syndrome compared with those treated with a FGA (Table 2). Other possible causes of metabolic syndrome are visceral adiposity and insulin resistance.¹⁶Management of the metabolic syndrome involves addressing the individual components that have been described in the preceding sections on T2DM and dyslipidemia.

Hepatitis C
Hepatitis C virus (HCV) infection is thought to be the most common blood-borne illness, with an estimated prevalence of 1% of the U.S. population. Some studies suggest that as many as 16% of people with schizophrenia have HCV infection.⁴ Risk factors for HCV infection include unsafe sexual practices, prostitution, homosexuality, homelessness, and IV drug use.

HCV treatments typically have involved regimens with interferon alfa, which is associated with significant neuropsychiatric side effects, including depression and suicide. There is a dearth of research on treatment of HCV in patients with schizophrenia; however, at least 1 study suggests that there was no increase in psychiatric symptoms in patients treated with interferon-containing regimens.²¹ There is even less evidence to guide the use of newer, non-interferon–based HCV treatment regimens that are better tolerated and have a higher response rate in the general population; there is reason, however, to be hopeful about their potential in patients with schizophrenia and HCV infection.

Managing HCV infection.

• Educate the patients and family about risk factors associated with contracting HCV.
• Screen for HCV infection in patients with schizophrenia because there is higher prevalence of HCV in these patients compared with the general population.
• When HCV infection is diagnosed, educate the patients and family about available treatments.
• Facilitate referral to an HCV specialist for appropriate treatment.

HIV/AIDS
HIV infection is highly prevalent among people suffering from severe mental illness such as schizophrenia. The incidence of HIV/AIDS in patients with schizophrenia is estimated to be 4% to 23%, compared with 0.6% in the general population.²² Risk factors associated with a higher incidence of HIV/AIDS in patients with schizophrenia are lack of knowledge about contracting HIV, unsafe sexual practices, prostitution, homosexuality, homelessness, and IV drug use.²²

Managing HIV/AIDS.

• Educate the patient and family about risk factors associated with contracting HIV/AIDS.
• Educate patients about safe sex practices.
• All patients with schizophrenia should be screened for HIV because there is 10-fold higher HIV prevalence in schizophrenia compared with the general population.
• When HIV infection is diagnosed, facilitate referral to a HIV or infectious disease specialist for treatment.
• Educate the patient in whom HIV/AIDS has been diagnosed about the importance of (1) adherence to his (her) HIV medication regimen and (2) follow-up visits with an infectious disease practitioner and appropriate laboratory tests.
• Educate the patient’s family and significant other about the illness.
• Screen for and treat substance use.
• At each visit, inquire about the patient’s adherence to HIV medical therapy, viral load, and CD4 cell count.

Chronic obstructive pulmonary disease
Patients with schizophrenia are more likely to suffer from respiratory disease, such as chronic obstructive pulmonary disease (COPD) and asthma, compared with the general population.²³ Smoking is a major risk factor for COPD. In a study by Dickerson et al,²⁴ 64% of people with schizophrenia were current smokers, compared with 19% of those without mental illness.

A high rate of smoking rate among people with schizophrenia suggests a “self-medication” hypothesis: That is, stimulation of CNS nicotinic cholinergic receptors treats the negative symptoms of schizophrenia and overcomes the dopamine blocking effects of antipsychotics.²⁵ Among SGAs, only clozapine has a substantial body of evidence to support its association with decreased smoking behavior.

Managing COPD.

• Educate the patient and family about risk factors associated with COPD and smoking.
• Screen for tobacco use at each visit; try to increase motivation to quit smoking.
• Educate the patients and family about the value and availability of smoking cessation programs.
• Prescribe medication to help with smoking cessation when needed. Bupropion and varenicline have been shown to be effective in patients with schizophrenia; nicotine replacement therapies are safe and can be helpful.
• When treating a patient who is in the process of quitting, encourage and help him to maintain his commitment and enlist support from his family.
• Refer to an appropriate medical provider (primary care provider or pulmonologist) for a patient with an established or suspected diagnosis of COPD.

There is a dearth of research on treatment of HCV in patients with schizophrenia; however, at least 1 study suggests that there was no increase in psychiatric symptoms in patients treated with interferon-containing regimens.²¹ There is even less evidence to guide the use of newer, non-interferon–based HCV treatment regimens that are better tolerated and have a higher response rate in the general population; there is reason, however, to be hopeful about their potential in patients with schizophrenia and HCV infection.

Managing HCV infection.

• Educate the patients and family about risk factors associated with contracting HCV.
• Screen for HCV infection in patients with schizophrenia because there is higher prevalence of HCV in these patients compared with the general population.
• When HCV infection is diagnosed, educate the patients and family about available treatments.
• Facilitate referral to an HCV specialist for appropriate treatment.

HIV/AIDS
HIV infection is highly prevalent among people suffering from severe mental illness such as schizophrenia. The incidence of HIV/AIDS in patients with schizophrenia is estimated to be 4% to 23%, compared with 0.6% in the general population.²² Risk factors associated with a higher incidence of HIV/AIDS in patients with schizophrenia are lack of knowledge about contracting HIV, unsafe sexual practices, prostitution, homosexuality, homelessness, and IV drug use.²²

Managing HIV/AIDS.

• Educate the patient and family about risk factors associated with contracting HIV/AIDS.
• Educate patients about safe sex practices.
• All patients with schizophrenia should be screened for HIV because there is 10-fold higher HIV prevalence in schizophrenia compared with the general population.
• When HIV infection is diagnosed, facilitate referral to a HIV or infectious disease specialist for treatment.
• Educate the patient in whom HIV/AIDS has been diagnosed about the importance of (1) adherence to his (her) HIV medication regimen and (2) follow-up visits with an infectious disease practitioner and appropriate laboratory tests.
• Educate the patient’s family and significant other about the illness.
• Screen for and treat substance use.
• At each visit, inquire about the patient’s adherence to HIV medical therapy, viral load, and CD4 cell count.

Chronic obstructive pulmonary disease
Patients with schizophrenia are more likely to suffer from respiratory disease, such as chronic obstructive pulmonary disease (COPD) and asthma, compared with the general population.²³ Smoking is a major risk factor for COPD. In a study by Dickerson et al,²⁴ 64% of people with schizophrenia were current smokers, compared with 19% of those without mental illness.

A high rate of smoking rate among people with schizophrenia suggests a “self-medication” hypothesis: That is, stimulation of CNS nicotinic cholinergic receptors treats the negative symptoms of schizophrenia and overcomes the dopamine blocking effects of antipsychotics.²⁵ Among SGAs, only clozapine has a substantial body of evidence to support its association with decreased smoking behavior.

Managing COPD.

• Educate the patient and family about risk factors associated with COPD and smoking.
• Screen for tobacco use at each visit; try to increase motivation to quit smoking.
• Educate the patients and family about the value and availability of smoking cessation programs.
• Prescribe medication to help with smoking cessation when needed. Bupropion and varenicline have been shown to be effective in patients with schizophrenia; nicotine replacement therapies are safe and can be helpful.
• When treating a patient who is in the process of quitting, encourage and help him to maintain his commitment and enlist support from his family.
• Refer to an appropriate medical provider (primary care provider or pulmonologist) for a patient with an established or suspected diagnosis of COPD.

Cancer
Since 1909, when the Board of Control of the Commissioners in Lunacy for England and Wales noted the possibility of a decreased incidence in cancer among psychiatric patients, this connection has been a matter of controversy.²⁶ Subsequent research has been equivocal; the prevalence of cancer has been reported to be either increased, similar, or decreased compared with the general population.^26-28 Risk factors for cancer, including smoking, obesity, poor diet, sedentary lifestyle, and hyperprolactinemia, are more common among patients with schizophrenia.

Genetic factors and a possible protective effect from antipsychotics have been cited as potential causes of decreased prevalence. Clozapine is associated with an increased risk of leukemia. No conclusion can be drawn about the overall prevalence of cancer in schizophrenia.

Managing cancer in a patient with schizophrenia, however, poses a significant challenge²⁹; he might lack capacity to make decisions about cancer treatment. The patient—or his surrogate decision-makers—need to carefully weigh current quality of life against potential benefits of treatment and risks of side effects. Adherence to complex, often toxic, therapies can be challenging for the patient with psychosis. Successful cancer treatment often requires close collaboration between the cancer treatment team and the patient’s support system, including the treating psychiatrist and case management teams.

Bottom Line
Patients with schizophrenia are at higher risk of developing comorbid medical
conditions because of the illness itself, lifestyle behaviors, genetics, and adverse
effects of medications. Because mental health clinicians focus attention on the
psychiatric and behavioral aspect of treatment, often there is delay in screening,
detecting, and treating medical comorbidities. This screening can be done in any
psychiatric practice, which can lead to timely management for those conditions
and preventing premature mortality in patients with schizophrenia.

Social media consumes the attention of the majority of teens. It is a place to express yourself, flirt, intimidate, and keep them up to date with the latest happenings in the social circles. But, teens are using social media for much more.

Denise Fulton/Frontline Medical News

Instagram, a social media site comprising photographs followed by comments, is one of the most common sites used by teens. They post everything from the meal they are eating to the new love in their life and everything in between.

A hashtag is a type of label or metadata tag used on social networks and microblogging services, which makes it easier for users to find messages with a specific theme or content. Users create hashtags by placing the hash character # (the number sign) in front of a word or unspaced phrase, either in the main text of a message or at the end. Searching for that hashtag will then present each message that has been tagged with it.¹ Although teens seem to prefer simple phrases, these hashtags are used to link users to what many refer to as “Secret Society.”

For example, if a teen girl was “cutting” or interested in connecting with other teens that cut, putting #cat would link her to several social communities with the related topic. Similarly, #selfharm was the initial term used to connect to this secret society. When that was shut down by the social media site, it resurfaced as #selfharmmm².

#MySecretFamily is a very popular hashtag that connects teens struggling with a variety of mental illnesses. Teens are instructed to put various names in their profile to identify which mental illness they are battling. For example, depression would be identified as “DEB” for a girl and “DAN” for a boy. The chart below lists various disorders.²

Nonsuicidal self-injury (NSSI) or deliberate destruction of one’s body in the absence of suicidal intent³ is most common in the middle school ages, and exposure to peer NSSI may increase the risk of engaging these behaviors.^2,4 Although distinct from suicidal behaviors, there is a comorbidity between them. The normalization of these behaviors through social media and acceptance into the this “Secret Society” can only augment the risk of NSSI.

Parents not only need to be educated about the importance of monitoring their children’s social media but also about what to look for that may be a sign that something more serious is going on with them.

Although we hear so much of the negative impact of social media, it also can be a tool for early intervention.

Oseltamivir and zanamivir are competitive inhibitors for the neuraminidase enzyme for the influenza virus. They block the surface receptor enzyme and prevent release of virus from the host cell, thus limiting propagation of the infection. These medications can be given as prophylaxis after exposure to influenza or can be given therapeutically for a suspected or confirmed infection. Oseltamivir is recommended for treatment of suspected or confirmed influenza infection in the special population of pregnant women, as the risk for complications of influenza is increased in this group.

Safety evidence

However, there are limited data on the safety and efficacy of the neuraminidase inhibitors in pregnancy. With respect to safety, there have been seven publications in the literature addressing the risk for major birth defects following treatment or prophylaxis with one or both of these products, with the majority of the published data relating to oseltamivir exposure.

In a review by Tanaka et al. in 2009, 90 pregnancies treated therapeutically with oseltamivir in the first trimester were reported to two teratogen information services in Japan; one major birth defect (1.1%) was reported (CMAJ. 2009 Jul 7;181[1-2]:55-8). A year later, Greer et al. published a retrospective chart review at a Texas hospital between 2003 and 2008. During that period, 137 pregnancies that involved a pharmacy record of dispensing of oseltamivir were identified. Of these, 18 were dispensed in the first trimester, and none were linked to a major birth defect outcome (Obstet Gynecol. 2010 Apr;115[4]:711-6).

A 2011 record linkage study in Sweden identified 86 pregnant women for whom oseltamivir (n=81) or zanamivir had been prescribed. Of these, four were linked to a major birth defect in the infant; however, only one of the four prescriptions had been filled in the first trimester (Pharmacoepidemiol Drug Saf. 2011 Oct;20[10]:1030-4). In 2013, Saito et al. reported on a case series gathered from 157 obstetric facilities in Japan. Among 156 infants born to women exposed to oseltamivir in the first trimester, 2 (1.3%) were reported to have a major congenital anomaly; there were no congenital malformations reported in the 15 first-trimester exposures to zanamivir (Am J Obstet Gynecol. 2013 Aug;209[2[:130.e1-9).

In 2014, a teratogen information service in the United Kingdom reported on eight first-trimester exposures to oseltamivir and 37 to zanamivir, with no major birth defects noted in either group (BJOG. 2014 Jun;121[7]:901-6). Additionally, a French prescription database study identified 49 pregnancies thought to be exposed to oseltamivir in the first trimester with one reported congenital anomaly (BJOG. 2014 Jun;121[7]:895-900).

Finally, the manufacturer of oseltamivir published a summary of pregnancies from global pharmacovigilance data accumulated through spontaneous reports and other studies between 2000 and 2012 (Pharmacoepidemiol Drug Saf. 2014 Oct;23[10]:1035-42). Outcomes were available for 1,875 infants. Among these, 81 (4.3%) had major birth defects. However, following case review, the authors indicated that only 11 of the defects (occurring in 9 infants) were biologically plausible based on the timing of the exposure to oseltamivir.

Efficacy examined

With respect to efficacy, two small studies have addressed the pharmacokinetics of oseltamivir in pregnancy to determine if the recommended dosages for nonpregnant individuals are appropriate for pregnancy.

In the earlier of the two studies, Greer et al. looked at the pharmacokinetics of oseltamivir in 30 pregnant women, 10 in each of the three trimesters, who were taking 75 mg of the drug either once or twice daily. Maternal samples were drawn before and after the first dose of oseltamivir. They found little evidence of differences across the three trimesters and concluded that the parent drug values were in the pharmacologic range for clinical efficacy (Am J Obstet Gynecol. 2011 Jun;204[6 Suppl 1]:S89-93).

In contrast, Pillai et al. enrolled a small sample of women being treated with oseltamivir; they evaluated pharmacokinetics for the active metabolite of oseltamivir following 48 or more hours of treatment in 29 pregnant and 35 nonpregnant women (Br J Clin Pharmacol. 2015 Nov;80[5]:1042-50). Significantly lower levels of the active metabolite were noted in the pregnant women, compared with nonpregnant women. The authors suggested that the physiologic changes of pregnancy, correlated with increased renal clearance, produced an approximate 30% lower exposure to the drug in the pregnant state. While they were not able to relate this to maternal or infant outcomes, this finding suggested that further work is needed to determine if dosing recommendations should be adjusted in pregnancy.

The current recommendation is that pregnant women or women within 2 weeks post partum be given oseltamivir for treatment of suspected or confirmed influenza regardless of trimester of pregnancy. The limited safety data that are currently available have not suggested an increased risk for major birth defects following treatment with this product. However, the data are sparse for oseltamivir and even more so for zanamivir. Larger studies focused on these treatments are needed.

CASE Mute and nonresponsive
Mr. R, a 19-year-old African-American man, is brought to the emergency room (ER) because he has reduced oral intake and mutism, and is not attending to activities of daily living (ADL). His family reports gradual onset of symptoms over the past month after he began using “Spice,” a synthetic cannabinoid (Box^1-8).

Mr. R has been using marijuana regularly for a few years. He has no history of psychiatric illness. The family history is positive for schizophrenia (mother).

Mr. R slowly stopped speaking and eating, and no longer responds to verbal stimulation. On examination, he responds only with unintelligible mumbling. Mr. R exhibits blunted affect and fails to maintain eye contact, looking to the side of the interviewer. He exhibits severe psychomotor retardation but without posturing or waxy flexibility. It takes him approximately 3 minutes to transfer between chairs, and he is incontinent of bladder and bowel.

Mr. R has not experienced a similar episode in the past, although he had exhibited brief paranoia while intoxicated with marijuana.

Before this episode, Mr. R had been moving between his grandmother’s and father’s homes and was attending high school classes. Recent stressful events include his brother’s incarceration and his father having re-entered his life after a long absence.

Which treatment would you initiate for Mr. R’s symptoms of catatonia?
   a) dantrolene
   b) a benzodiazepine
   c) an antipsychotic
   d) electroconvulsive therapy (ECT)

The authors’ observations
Catatonia is a common complication in a variety of psychiatric and medical contexts. It can be a feature of mood disorders, schizophrenia, metabolic disturbances, drug intoxication, neuroleptic malignant syndrome (NMS), and encephalopathy. The most common psychiatric comorbidity is bipolar disorder; as many as 25% of cases are caused by a medical or neurological condition.⁹ When accompanied by fever and autonomic instability, so-called malignant catatonia can lead to respiratory failure, coma, and death.

Catatonia is characterized by ≥3 of the elements outlined in Table 1.¹⁰

In DSM-5, catatonia is no longer considered a subtype of schizophrenia, but is a specifier in the following disorders: brief psychotic disorder, schizophreniform disorder, schizoaffective disorder, and substance-induced psychotic disorder. In addition, catatonia not otherwise specified is reserved for cases when the cause is not apparent; this diagnosis is intended to lead to greater recognition of catatonia and prompt initiation of treatment. DSM-5 stops short of classifying catatonia as an independent syndrome, however. Changes in clinical status can be charted with instruments such as the Bush-Francis Catatonia Rating Scale.

Workup and treatment
The initial workup of patients with catatonia is extensive. A basic metabolic panel can detect electrolyte disturbances and acute renal failure. Monitoring creatine kinase (CK) allows clinicians to assess for rhabdomyolysis. Patients should also undergo an infectious workup, including complete blood count (CBC) and chest radiography, because patients can develop pneumonia due to atelectasis or aspiration. Additional workup could include EEG, erythrocyte sedimentation rate, D-dimer, urinalysis, urine drug screen, antinuclear antibodies, magnetic resonance imaging, cerebrospinal fluid analysis, anti-N-methyl-D-aspartate receptor antibodies, and serum iron, which could predict development of NMS in patients treated with an antipsychotic.¹¹

Treatment. In addition to supportive measures, the initial treatment of choice for catatonia is a benzodiazepine, lorazepam being the most commonly used agent; dramatic improvement in symptoms can be seen within minutes of IV administration. A high dosage of lorazepam (14 to 16 mg/d) sometimes is required for symptomatic relief. Zolpidem also has been used successfully to treat catatonia, although the supporting literature is less extensive.¹²

Antipsychotics generally are held during the initial stages of catatonia treatment because they can exacerbate symptoms and increase the likelihood of NMS. Glutamate antagonists, such as amantadine and memantine, also are being investigated for treating catatonia.⁹

ECT is effective but is reserved for when pharmacotherapy has failed or when a rapid response is required. ECT is associated with cognitive and medical complications, although current techniques have greatly mitigated the risks. Mortality is estimated to be 1 in every 10,000 patients or 1 for every 80,000 treatments, most often due to a cardiac or pulmonary cause.¹³ Patients receiving ECT could experience temporary anterograde amnesia and confusion as well as retrograde amnesia, particularly memories formed around the time of treatment.

Response to benzodiazepine therapy varies: Some patients experience significant improvement after 1 dose; others require a high dosage for an extended period. More than 70% of cases remit with benzodiazepines; ECT should be considered after several days or earlier if indicated.⁹ Some patients with catatonia require a slow benzodiazepine taper to prevent symptoms from recurring.

Patients with catatonia are at risk of dehydration and malnutrition, and might require IV fluids or parenteral nutrition. These patients also are at risk of constipation, ileus, decubitus ulcers, deep vein thrombosis, and pulmonary embolism. Encourage early ambulation and consider prescribing an antithrombotic. Some patients might require physical therapy to prevent or treat muscle contractures.

TREATMENT Benzodiazepines, ECT
Mr. R is admitted for stabilization of catatonic symptoms. A basic metabolic panel, CBC with differential, urine drug screen, urinalysis, folate level, thyroid-stimulating hormone level, vitamin B₁₂, EEG, and a stool culture are unremarkable. Ammonia level is slightly elevated at 40 µmol/L.

Mr. R is started on IM lorazepam, 1 mg every 8 hours. Antipsychotics are held in part because of an elevated CK level (614 U/L). CK is rechecked daily and increases to 5,681 U/L by the second week. Internal medicine is consulted because Mr. R could develop NMS. However, the treatment team thinks that CK elevation is caused by immobility, because Mr. R remains afebrile, normotensive, and without leukocytosis.

After 4 days of treatment, Mr. R can follow simple commands. He nods or shakes his head when questioned. IV fluids are started because of limited oral intake. As the month progresses, Mr. R’s CK levels slowly trend downward, toward 500 U/L.

Mr. R progresses slowly with benzodiazepine therapy. He begins to ambulate, make eye contact, and look at interviewers. Lorazepam is slowly titrated to 4 mg IM every 8 hours. On hospital Day 20, his functioning reaches a plateau; Mr. R’s cognition continues to fluctuate with periods of unresponsiveness, immobility, and incontinence.

The treatment team obtains consent from the family to begin ECT. On hospital Day 24, bilateral transtemporal ECT is initiated and continued 3 times a week. Mr. R tolerates the procedure without complications. After the first treatment, he demonstrates spontaneous speech for the first time since admission. He continues to improve overall but has a variable clinical course.

By Day 30, Mr. R can state the day, month, year, and that he is in the “psych” unit. He remembers being on the unit for a long time and says that he had been attempting to talk but “it wasn’t coming out.” When further questioned about substance use, he admits to using Spice for the month before admission and marijuana regularly over several years. He denies using other illicit drugs or alcohol.

Mr. R is started on olanzapine, 2.5 mg/d, titrated to 15 mg/d. He becomes increasingly interactive, although with occasional bouts of confusion, and regains bladder and bowel control. He receives a total of 12 ECT treatments. The family is adamant that Mr. R should not receive more ECT treatments, and is not interested in maintenance therapy. Mr. R’s father and grandmother visit and believe that he is back to baseline functioning. After 51 days of inpatient treatment, Mr. R is discharged on olanzapine, 15 mg/d, and oral lorazepam, 1 mg/d.

Nine days later, Mr. R is brought to the ER because of unresponsiveness, poor oral intake, refusal of medication, bowel and bladder incontinence, and inability to perform ADL. His father reports that he administered olanzapine but, because he only recognized the brand name of lorazepam, he did not get that prescription filled. Mr. R slowly decompensates and, by the time of readmission, refuses all medications.

Over the next few months, Mr. R is readmitted several times for similar symptoms. Again, the family states they do not want further ECT; the father believes that these treatments have caused his son’s condition. Complicating the matter is that the father had been out of his son’s life for an extended period and is unaccustomed to his son’s display of psychiatric symptoms.

The authors’ observations
The use of ECT for drug-induced psychosis is not well described in the literature because substance abuse is exclusionary in many trials. The safety and efficacy of ECT has been established for adolescents with first-episode psychosis¹⁴ and with catatonia.^15,16

The use of ECT in Spice-induced catatonia has been reported in 2 case studies.^17,18

Case 1. A 36-year-old man with schizophrenia and Cannabis dependence was admitted for auditory hallucinations, disorganization, paranoia, and manic symptoms, which progressed to catatonia.¹⁷ His symptoms were profound, including psychomotor retardation, rigidity, posturing, waxy flexibility, and inability to perform ADL.

The patient later reported that, 3 weeks prior, he had stopped taking his psychotropic medications and started smoking “K2,” a synthetic cannabinoid, because it was cheaper and easier to obtain than Cannabis. He had never experienced disturbances in motor function or speech in the past, even during episodes of Cannabis use and medication non-adherence.

After clozapine and benzodiazepine treatment (as high as 12 mg/d of lorazepam) did not resolve his symptoms, the patient received 6 bilateral ECT treatments over 16 days, with complete resolution of catatonic symptoms. He showed marked improvement, including resumption of speech after the first treatment, although he required an additional 20 days of inpatient care. As in our case, exposure to synthetic cannabinoids was self-reported; no confirmatory tests were performed.

Case 2. A 17-year-old male with no history of psychosis exhibited catatonic symptoms after smoking an estimated 2 to 3 g/d of K2 over 2 months.¹⁸ Similar to the case of Mr. R, he plateaued after lorazepam treatment, and then received 6 ECT treatments, which resulted in complete resolution of symptoms. He was discharged with olanzapine.

As our patient, and the 2 cases cited, show, ECT seems to be an effective option for Spice-induced catatonia. Unlike those published cases, however, our patient achieved only brief resolution of symptoms after an acute course of ECT. There appears to be a subset of patients who require maintenance ECT or prolonged benzodiazepine therapy after Spice-induced catatonia.

CASE Mute and nonresponsive
Mr. R, a 19-year-old African-American man, is brought to the emergency room (ER) because he has reduced oral intake and mutism, and is not attending to activities of daily living (ADL). His family reports gradual onset of symptoms over the past month after he began using “Spice,” a synthetic cannabinoid (Box^1-8).

Mr. R has been using marijuana regularly for a few years. He has no history of psychiatric illness. The family history is positive for schizophrenia (mother).

Mr. R slowly stopped speaking and eating, and no longer responds to verbal stimulation. On examination, he responds only with unintelligible mumbling. Mr. R exhibits blunted affect and fails to maintain eye contact, looking to the side of the interviewer. He exhibits severe psychomotor retardation but without posturing or waxy flexibility. It takes him approximately 3 minutes to transfer between chairs, and he is incontinent of bladder and bowel.

Mr. R has not experienced a similar episode in the past, although he had exhibited brief paranoia while intoxicated with marijuana.

Before this episode, Mr. R had been moving between his grandmother’s and father’s homes and was attending high school classes. Recent stressful events include his brother’s incarceration and his father having re-entered his life after a long absence.

Which treatment would you initiate for Mr. R’s symptoms of catatonia?
   a) dantrolene
   b) a benzodiazepine
   c) an antipsychotic
   d) electroconvulsive therapy (ECT)

The authors’ observations
Catatonia is a common complication in a variety of psychiatric and medical contexts. It can be a feature of mood disorders, schizophrenia, metabolic disturbances, drug intoxication, neuroleptic malignant syndrome (NMS), and encephalopathy. The most common psychiatric comorbidity is bipolar disorder; as many as 25% of cases are caused by a medical or neurological condition.⁹ When accompanied by fever and autonomic instability, so-called malignant catatonia can lead to respiratory failure, coma, and death.

Catatonia is characterized by ≥3 of the elements outlined in Table 1.¹⁰

In DSM-5, catatonia is no longer considered a subtype of schizophrenia, but is a specifier in the following disorders: brief psychotic disorder, schizophreniform disorder, schizoaffective disorder, and substance-induced psychotic disorder. In addition, catatonia not otherwise specified is reserved for cases when the cause is not apparent; this diagnosis is intended to lead to greater recognition of catatonia and prompt initiation of treatment. DSM-5 stops short of classifying catatonia as an independent syndrome, however. Changes in clinical status can be charted with instruments such as the Bush-Francis Catatonia Rating Scale.

NEW YORK (Reuters Health) - Implementation of a patient-centered medical home (PCMH) resulted in small changes in utilization patterns and modest quality improvements over a three-year period, according to a new report.

Dr. Lisa M. Kern of Weill Cornell Medical College in New York City and colleagues found more primary care visits, fewer specialist visits, fewer lab and radiologic tests, and fewer hospitalizations and rehospitalizations in the practices that adopted the PCMH.

Most changes occurred in the last year of the study, three years after PCMH implementation, they report in the Annals of Internal Medicine, online February 15.

The PCMH model "attempts to shift the medical paradigm from care for individual patients to care for populations, from care by physicians to care by a team of providers, from a focus on acute illness to an emphasis on chronic disease management, and from care at a single site to coordinated care across providers and settings," Dr. Kern and her team write. However, they add, studies looking at the effectiveness of the approach have had mixed results.

To date, most studies attempting to look at PCMH have had follow-up periods lasting just 1.5 to 2 years after implementation, the researchers note. "These changes take time, and studies with relatively short follow-up may have underestimated the effects of the intervention," they add.

The new study included 438 primary care physicians in 226 practices with more than 136,000 patients enrolled in five health plans. Insurers offered incentives of $2 to $10 per patient per month to practices that achieved level III PCMH recognition from the National Committee for Quality Assurance

(NCQA).

Twelve practices including 125 physicians volunteered for the PCMH initiative, and were assisted by two outside consulting groups. All of these practices achieved level III PCMH recognition. Among the remaining physicians, 87 doctors in 45 practices adopted electronic health records (EHR) without the

PCMH intervention, and 226 physicians in 169 practices continued using paper records.

For the eight quality measures the researchers looked at, two showed greater improvements over time in the PCMH group compared to one or both of the control groups: eye examination and hemoglobin A1c testing for patients with diabetes.

From 2008 to 2012, the PCMH group showed improvements over the paper group and the EHR group for six of seven utilization measures.

NCQA recognition was one aspect of the PCMH intervention in the new study, but this doesn't represent the entire intervention, Dr. Mark W. Friedberg of RAND Corporation and Brigham and Women's Hospital in Boston, who wrote an editorial accompanying the study, told Reuters Health.

"What they evaluated was a different way of paying practices, combined with some technical assistance, combined with some shared savings in the last year of the pilot," Dr. Friedberg explained. And this also requires defining what improving care means, he added, for example "better technical quality of care, better patient experience, better effectiveness of care, better professional satisfaction and lower burnout for people working in the practices. It's also hard to measure all of those, and most studies don't."

The new study is well done, according to Dr. Friedberg, but the challenge will be to understand how it fits in with the rest of the medical home literature, he said. "There's a lot of trials still out there and the results are still coming in, including some very large Medicare medical home pilots. I think we'll have a much better sense of what works in a year or two as those results come back."

Dr. Kern did not respond to an interview request by press time.

The study was funded by The Commonwealth Fund and the New York State Department of Health.

However, they add, studies looking at the effectiveness of the approach have had mixed results.

To date, most studies attempting to look at PCMH have had follow-up periods lasting just 1.5 to 2 years after implementation, the researchers note. "These changes take time, and studies with relatively short follow-up may have underestimated the effects of the intervention," they add.

The new study included 438 primary care physicians in 226 practices with more than 136,000 patients enrolled in five health plans. Insurers offered incentives of $2 to $10 per patient per month to practices that achieved level III PCMH recognition from the National Committee for Quality Assurance

(NCQA).

Twelve practices including 125 physicians volunteered for the PCMH initiative, and were assisted by two outside consulting groups. All of these practices achieved level III PCMH recognition. Among the remaining physicians, 87 doctors in 45 practices adopted electronic health records (EHR) without the

PCMH intervention, and 226 physicians in 169 practices continued using paper records.

For the eight quality measures the researchers looked at, two showed greater improvements over time in the PCMH group compared to one or both of the control groups: eye examination and hemoglobin A1c testing for patients with diabetes.

From 2008 to 2012, the PCMH group showed improvements over the paper group and the EHR group for six of seven utilization measures.

NCQA recognition was one aspect of the PCMH intervention in the new study, but this doesn't represent the entire intervention, Dr. Mark W. Friedberg of RAND Corporation and Brigham and Women's Hospital in Boston, who wrote an editorial accompanying the study, told Reuters Health.

"What they evaluated was a different way of paying practices, combined with some technical assistance, combined with some shared savings in the last year of the pilot," Dr. Friedberg explained. And this also requires defining what improving care means, he added, for example "better technical quality of care, better patient experience, better effectiveness of care, better professional satisfaction and lower burnout for people working in the practices. It's also hard to measure all of those, and most studies don't."

The new study is well done, according to Dr. Friedberg, but the challenge will be to understand how it fits in with the rest of the medical home literature, he said. "There's a lot of trials still out there and the results are still coming in, including some very large Medicare medical home pilots. I think we'll have a much better sense of what works in a year or two as those results come back."

Dr. Kern did not respond to an interview request by press time.

NEW YORK (Reuters Health) - Implementation of a patient-centered medical home (PCMH) resulted in small changes in utilization patterns and modest quality improvements over a three-year period, according to a new report.

Dr. Lisa M. Kern of Weill Cornell Medical College in New York City and colleagues found more primary care visits, fewer specialist visits, fewer lab and radiologic tests, and fewer hospitalizations and rehospitalizations in the practices that adopted the PCMH.

Patients who have chronic pain and those with a major depressive disorder (MDD) share clinical features, including fatigue, cognitive complaints, and functional limitation. Sleep disturbance and anxiety are common with both disorders. Because pain and depression share common neurobiological pathways (see Part 1 of this article in the February 2016 issue and at CurrentPsychiatry.com) and clinical manifestations, you can use similar strategies and, often, the same agents to treat both conditions when they occur together (Table 1).

What are the medical options?
Antidepressants. Using an antidepressant to treat chronic pain is a common practice in primary care and specialty practice. Antidepressants that modulate multiple neurotransmitters appear to be more efficacious than those with a single mechanism of action.¹ Convergent evidence from preclinical and clinical studies supports the use of serotonin-norepinephrine reuptake inhibitors (SNRIs) as more effective analgesic agents, compared with the mostly noradrenergic antidepressants, which, in turn, are more effective than selective serotonin reuptake inhibitors (SSRIs).² The mechanism of the analgesic action of antidepressants appears to rely on their inhibitory effects of norepinephrine and serotonin reuptake, thereby elevating the performance of endogenous descending pain regulatory pathways.³

Tricyclic antidepressants (TCAs), primarily amitriptyline, nortriptyline, and desipramine, have the advantage of years of clinical experience and low cost. Their side effect burden, however, is higher, especially in geriatric patients. Dose-dependent side effects include sedation, constipation, dry mouth, urinary retention, and orthostatic hypotension.

TCAs must be used with caution in patients with suicidal ideation because of the risk of a potentially lethal intentional overdose.

The key to using a TCA is to start with a low dosage, followed by slow titration. Typically, the dosages of TCAs used in clinical trials that focused on pain have been lower (25 to 100 mg/d of amitriptyline or equivalent) than the dosage typically necessary for treating depression; however, some experts have found that titrating TCAs to higher dosages with an option of monitoring serum levels may benefit some patients.⁴

SNRIs are considered first-line agents for both neuropathic pain and fibromyalgia. Duloxetine has been shown to be effective in both conditions⁵; venlafaxine also has shown efficacy in neuropathic pain.⁶ Milnacipran, another SNRI that blocks 5-HT, and norepinephrine equally and exerts a mild N-methyl-D-aspartate inhibition, has proven efficacy in fibromyalgia.^7,8

SSRIs for alleviating central pain or neuropathic pain are supported by minimal evidence only.⁹ A review of the effectiveness of various antidepressants on pain in diabetic neuropathy concluded that fluoxetine was no more effective than placebo.^10,11 Schreiber and Pick¹¹ evaluated the antinociceptive properties of several SSRIs and offered the opinion that fluoxetine, fluvoxamine, and citalopram were, at best, weak antinociceptors.

Opioids. Data on the long-term benefits of opioids are limited, except for use in carefully selected patients; in any case, risk of abuse, diversion, and even death with these agents is quite high.¹² Also, there is evidence that opioid-induced hyperalgesia might limit the usefulness of opioids for controlling chronic pain.¹³

Gabapentin and pregabalin, both anticonvulsants, act by binding to the α-2-σ subunit of voltage-gated calcium channels within the CNS.¹⁴ By reducing calcium influx at nerve terminals, the drugs diminish the release of several neurotransmitters, including glutamate, noradrenaline, and substance P. This mechanism is thought to be the basis for the analgesic, anticonvulsant, and anxiolytic effects of these drugs.¹⁵

Gabapentin and pregabalin have been shown to decrease pain intensity and improve quality of life and function in patients with neuropathic pain conditions. Pregabalin also has shown efficacy in treating central neuropathic pain and fibromyalgia.¹⁶

Added benefits of these drugs is that they have (1) a better side effect profile than TCAs and (2) fewer drug interactions when they are used as a component of combination therapy. Pregabalin has the additional advantage of less-frequent dosing, linear pharmacokinetics, and a predictable dose-response relationship.¹⁷

Addressing other comorbid psychiatric conditions
Sleep disturbance is common among patients with chronic pain. Sleep deprivation causes a hyperexcitable state that amplifies the pain response.¹⁸

When a patient presents with chronic pain, depression, and disturbed sleep, consider using a sedating antidepressant, such as a TCA. Alternatively, gabapentin or pregabalin can be added to an SNRI; anticonvulsants have been shown to improve quality of sleep.¹⁹ Cognitive-behavioral interventions targeting sleep disturbance may be a helpful adjunct in these patients.²⁰

When anxiety is comorbid with chronic pain, antidepressants with proven efficacy in treating anxiety disorders, such as duloxetine or venlafaxine, can be used. When chronic pain coexists with a specific anxiety disorder (social anxiety disorder, obsessive-compulsive disorder, panic disorder), an SSRI might be more advantageous than an SNRI,²¹ especially if it is combined with a more efficacious analgesic.

Benzodiazepines should be avoided as a routine treatment for comorbid anxiety and pain, because these agents can produce sedation and cognitive interference, and carry the potential for dependence.

Fatigue. In patients who, in addition to pain and depression, complain of fatigue, an activating agent such as milnacipran or adjunct bupropion might be preferable to other agents. Modafinil has been shown to be a well-tolerated and potentially effective augmenting agent for antidepressants when fatigue and sleepiness are present as residual symptoms²²; consider them as adjuncts when managing patients who have chronic pain and depression that manifests as excessive sleepiness and/or fatigue.

Cognitive complaints. We have noted that disturbances of cognition are common in patients with depression and chronic pain, and that cognitive dysfunction might improve after antidepressant treatment.

Studies suggest that SSRIs, duloxetine, and other antidepressants, such as bupropion, might exert a positive effect on learning, memory, and executive function in depressed patients.²³ Beneficial effects of antidepressants may be “pseudo-specific,” however—that is, predominantly a reflection of overall improvement in mood, not on specific amelioration of the cognitive disturbance.

Vortioxetine has shown promise in improving cognitive function in adults with MDD; its cognitive benefits are largely independent of its antidepressant effect.²⁴ The utility of vortioxetine in chronic pain patients has not been studied, but its positive impact on mood, anxiety, sleep, and cognition might make it a consideration for patients with comorbid depression—although it is uncertain at this time whether putative noradrenergic activity makes it suitable for use in chronic pain disorders.

Last, avoid TCAs in patients who have cognitive complaints. These agents have anticholinergic effects that can have an adverse impact on cognitive function.

Cautions: Drug−drug interactions, suicide risk, disrupted sleep
Avoiding drug−drug interactions is an important consideration when treating comorbid disorders. Many chronic pain patients take over-the-counter or prescribed nonsteroidal anti-inflammatory drugs for analgesia; these agents can increase the risk of gastrointestinal bleeding when they are combined with an SSRI or an SNRI.

The use of the opioid tramadol with an SNRI or a TCA is discouraged because of the risk of serotonin syndrome.

Combining a sedating antidepressant, such as a TCA, with gabapentin or pregabalin can increase the risk of CNS depression and psychomotor impairment, especially in geriatric patients. An opioid analgesic is likely to amplify these effects.

Suicidal ideation is not uncommon in patients with chronic pain and depression. To minimize the risk of suicide in patients with a chronic pain disorder, you should ensure optimal pain control by combining the most efficacious analgesic agent with psychotherapeutic interventions and optimal antidepressant treatment. Furthermore, cognitive-behavioral therapy (CBT) (see the discussion below) might not only improve pain coping skills, but also ameliorate catastrophizing, anxiety, and concomitant sleep disturbance.

Complaints of sleep disturbance and anxiety can compound the risk of suicide in a chronic pain patient. When possible, these complex patients should be treated by a multidisciplinary team that includes a pain management specialist, psychotherapist, and primary care clinician. It is important to strengthen the clinician−patient relationship to facilitate close monitoring of symptoms and to provide a trusting environment in which patients feel free to discuss thoughts of suicide or self-harm. For such patients, prescribing opiates and TCAs in small quantities is a prudent action.

When a patient struggles with suicidal thoughts, his (her) family might need to dispense these medications. Most important, if a patient is actively suicidal, consider referral to an inpatient facility or intensive outpatient program, where aggressive treatment of depressive symptoms and intensive monitoring and support can be provided.²⁵

Usefulness of non-drug interventions
There is, of course, a diversity of non-drug treatments for MDD and for chronic pain; discussion here focuses primarily on modalities with established efficacy in both disease states (Table 2). On rare occasions, non-drug treatments can constitute a stand-alone approach; most often, they are incorporated into a multimodal treatment plan or applied as an adjunct intervention.²⁶

Psychotherapy. The most robust evidence supports the use of CBT in addressing MDD and chronic pain—occurring individually and comorbidly.^26-28 Efficacy is well established in MDD, as monotherapy and adjunct treatment, spanning acute and maintenance phases.

Furthermore, CBT also has support from randomized trials, meta-analyses, and treatment guidelines, either as monotherapy or co-therapy for both short-term relief and long-term pain reduction. Additionally, CBT has demonstrated value for relieving pain-related disability.^26,28

Combination of a special form of CBT, rumination-focused CBT with ongoing pharmacological therapy over a 26-week period in a group of medication-refractory MDD patients produced a remission rate of 62%, compared with 21% in a treatment-as-usual group.²⁹ This is of particular interest in chronic pain patients, because rumination-related phenomena of pain catastrophizing and avoidance facilitate a transition from acute to chronic pain, while augmenting pain severity and associated disability.³⁰

Catastrophizing also has been implicated in mediating the relationship between pain and sleep disturbance. Not surprisingly, a randomized controlled study demonstrated the benefit of 8-week, Internet-delivered CBT in patients suffering from comorbid chronic pain, depression, and anxiety. Treatment significantly diminished pain catastrophizing, depression, and anxiety; maintenance of improvement was demonstrated after 1 year of follow-up.³¹

Other behavioral and psychological approaches. Biofeedback, mindfulness-based stress reduction, relaxation training and diaphragmatic breathing, guided imagery, hypnosis, and supportive groups might play an important role as components of an integrated mind−body approach to chronic pain,^28,32,33 while also providing mood benefits.

Exercise. The role of exercise as a primary treatment of MDD continues to be controversial, but its benefits as an add-on intervention are indisputable. Exercise not only complements pharmacotherapy to produce greater reduction in depressive scores and improvement in quality of life, it might aid in reestablishing social contacts when conducted in a group setting—an effect that can be of great value in both MDD and chronic pain.³⁴

Exercise and restorative therapies provide several benefits for chronic pain patients, including:

• improved pain control, cognition, and mood
• greater strength and endurance
• cardiovascular and metabolic benefits
• improved bone health and functionality.^{26,28,32,33,35}

To achieve optimal benefit, an exercise program must be customized to fit the patient’s physical condition, level of fitness, and specific type of pain.³⁵ Preliminary evidence suggests that, beyond improvement in pain and functionality, exercise might reduce depressive symptoms in chronic pain patients.³⁶

Patients who have chronic pain and those with a major depressive disorder (MDD) share clinical features, including fatigue, cognitive complaints, and functional limitation. Sleep disturbance and anxiety are common with both disorders. Because pain and depression share common neurobiological pathways (see Part 1 of this article in the February 2016 issue and at CurrentPsychiatry.com) and clinical manifestations, you can use similar strategies and, often, the same agents to treat both conditions when they occur together (Table 1).

Vortioxetine has shown promise in improving cognitive function in adults with MDD; its cognitive benefits are largely independent of its antidepressant effect.²⁴ The utility of vortioxetine in chronic pain patients has not been studied, but its positive impact on mood, anxiety, sleep, and cognition might make it a consideration for patients with comorbid depression—although it is uncertain at this time whether putative noradrenergic activity makes it suitable for use in chronic pain disorders.

Last, avoid TCAs in patients who have cognitive complaints. These agents have anticholinergic effects that can have an adverse impact on cognitive function.

Cautions: Drug−drug interactions, suicide risk, disrupted sleep
Avoiding drug−drug interactions is an important consideration when treating comorbid disorders. Many chronic pain patients take over-the-counter or prescribed nonsteroidal anti-inflammatory drugs for analgesia; these agents can increase the risk of gastrointestinal bleeding when they are combined with an SSRI or an SNRI.

The use of the opioid tramadol with an SNRI or a TCA is discouraged because of the risk of serotonin syndrome.

Combining a sedating antidepressant, such as a TCA, with gabapentin or pregabalin can increase the risk of CNS depression and psychomotor impairment, especially in geriatric patients. An opioid analgesic is likely to amplify these effects.

Suicidal ideation is not uncommon in patients with chronic pain and depression. To minimize the risk of suicide in patients with a chronic pain disorder, you should ensure optimal pain control by combining the most efficacious analgesic agent with psychotherapeutic interventions and optimal antidepressant treatment. Furthermore, cognitive-behavioral therapy (CBT) (see the discussion below) might not only improve pain coping skills, but also ameliorate catastrophizing, anxiety, and concomitant sleep disturbance.

Complaints of sleep disturbance and anxiety can compound the risk of suicide in a chronic pain patient. When possible, these complex patients should be treated by a multidisciplinary team that includes a pain management specialist, psychotherapist, and primary care clinician. It is important to strengthen the clinician−patient relationship to facilitate close monitoring of symptoms and to provide a trusting environment in which patients feel free to discuss thoughts of suicide or self-harm. For such patients, prescribing opiates and TCAs in small quantities is a prudent action.

When a patient struggles with suicidal thoughts, his (her) family might need to dispense these medications. Most important, if a patient is actively suicidal, consider referral to an inpatient facility or intensive outpatient program, where aggressive treatment of depressive symptoms and intensive monitoring and support can be provided.²⁵

Usefulness of non-drug interventions
There is, of course, a diversity of non-drug treatments for MDD and for chronic pain; discussion here focuses primarily on modalities with established efficacy in both disease states (Table 2). On rare occasions, non-drug treatments can constitute a stand-alone approach; most often, they are incorporated into a multimodal treatment plan or applied as an adjunct intervention.²⁶

Psychotherapy. The most robust evidence supports the use of CBT in addressing MDD and chronic pain—occurring individually and comorbidly.^26-28 Efficacy is well established in MDD, as monotherapy and adjunct treatment, spanning acute and maintenance phases.

Furthermore, CBT also has support from randomized trials, meta-analyses, and treatment guidelines, either as monotherapy or co-therapy for both short-term relief and long-term pain reduction. Additionally, CBT has demonstrated value for relieving pain-related disability.^26,28

Combination of a special form of CBT, rumination-focused CBT with ongoing pharmacological therapy over a 26-week period in a group of medication-refractory MDD patients produced a remission rate of 62%, compared with 21% in a treatment-as-usual group.²⁹ This is of particular interest in chronic pain patients, because rumination-related phenomena of pain catastrophizing and avoidance facilitate a transition from acute to chronic pain, while augmenting pain severity and associated disability.³⁰

Catastrophizing also has been implicated in mediating the relationship between pain and sleep disturbance. Not surprisingly, a randomized controlled study demonstrated the benefit of 8-week, Internet-delivered CBT in patients suffering from comorbid chronic pain, depression, and anxiety. Treatment significantly diminished pain catastrophizing, depression, and anxiety; maintenance of improvement was demonstrated after 1 year of follow-up.³¹

Other behavioral and psychological approaches. Biofeedback, mindfulness-based stress reduction, relaxation training and diaphragmatic breathing, guided imagery, hypnosis, and supportive groups might play an important role as components of an integrated mind−body approach to chronic pain,^28,32,33 while also providing mood benefits.

Exercise. The role of exercise as a primary treatment of MDD continues to be controversial, but its benefits as an add-on intervention are indisputable. Exercise not only complements pharmacotherapy to produce greater reduction in depressive scores and improvement in quality of life, it might aid in reestablishing social contacts when conducted in a group setting—an effect that can be of great value in both MDD and chronic pain.³⁴

Exercise and restorative therapies provide several benefits for chronic pain patients, including:

• improved pain control, cognition, and mood
• greater strength and endurance
• cardiovascular and metabolic benefits
• improved bone health and functionality.^{26,28,32,33,35}

To achieve optimal benefit, an exercise program must be customized to fit the patient’s physical condition, level of fitness, and specific type of pain.³⁵ Preliminary evidence suggests that, beyond improvement in pain and functionality, exercise might reduce depressive symptoms in chronic pain patients.³⁶

The National Football League (NFL) had its highest concussion tally last year: 182 such injuries reported¹ in the 2014-2015 regular season. The true rate of concussion in the NFL is likely higher, as a result of multiple factors (fear of “letting the team [or the coach] down,” fear of retaliation from team owners,² etc.).

To simply call a head injury a “concussion” is a disservice to players and their family: Any blow to the head, severe or otherwise, has the potential to cause microvascular disruption in the brain; repeated blows to the head undoubtedly cause further damage.

In reality, a “concussion” is a mild traumatic brain injury (mTBI). With repeated blows, an mTBI can lead to chronic traumatic encephalopathy (CTE). In 2015, eighty-seven of 91 brains from autopsied former NFL players displayed some stage of CTE.³

Pathophysiology and presentation
CTE comprises 4 histological stages; Stage 4 is the most advanced. Alzheimer’s disease (AD) and CTE display similarities, which suggests a separate classification of CTE-AD; the presence of amyloid β plaques correlates with (1) more severe hyperphosphorylated tau (pTau) pathology and (2) advanced stages of the disease and clinical presentations. Death tends to occur 10 years earlier in CTE-AD than in AD, suggesting that repetitive mTBI might change the deposition and accumulation of amyloid β plaques, and even accelerate the aging process in the brain.⁴

Symptoms. The case series by Omalu et al⁴ (which inspired the 2015 motion picture Concussion) and the case series presented by McKee et al⁵ described severe psychiatric symptoms associated with CTE:

• decreased speed of information processing
• increase in religiosity
• lack of insight
• poor judgment
• involvement in illegal activities
• substance abuse
• indiscretion
• verbal and physical abuse
• problems with interpersonal relationships
• isolation
• restlessness and hyperactivity
• somatic complaints.

The 2 groups of researchers also noted hopelessness, social phobia, anxiety, agitation, mania, labile mood, insomnia, explosivity, and suicidal ideation, attempt, and completion.^4,5

By Stage 4, all affected patients are symptomatic. Cognitive impairment is severe; many are described as having “severe memory loss with dementia,”⁵ “profound” inattention and loss of concentration,⁵ and dysarthria. Paranoia may develop. Mood symptoms can be severe: Approximately 31% of subjects studied have contemplated suicide; of those, 26% had “suicidal tendencies” and 14% completed suicide.⁵

Two distinct types of CTE progression are apparent:

• patients who display cognitive deficits first; they progress to dementia but live longer
• patients who display mood and behavioral symptoms first; they tend to be younger, more violent, depressed, and explosive.⁶

CTE cannot be diagnosed with imaging. There are, however, a few positron emission tomography (PET) ligands for pTau that show promise:

• [F-18]FDDNP, which consistently identifies pTau deposits in brains in which CTE is clinically suspected, in the same distribution of pTau neurofibrillary tangles on autopsy.
• [11C]DPA-713, which detected TBI-related inflammation of neurons in 9 former NFL players in whom CTE was suspected based on the clinical presentation.
• PiB amyloid ligand, under investigation for use in PET neuroimaging.⁷

Casualties
In January 2016 alone, at least 3 former NFL players were found to have CTE posthumously.

Earl Morrall. Former quarterback who had a 21-year NFL career. Official cause of death in 2014 at age 79 was recorded as “complications of Parkinson’s disease.” In 2016, Stage-4 CTE was discovered on autopsy.⁸

Ken Stabler. Former quarterback for several NFL teams over 15 seasons. Died of colon cancer at age 69 in 2015. On autopsy, was found to have Stage-3 CTE.⁹

Tyler Sash. Former University of Iowa and New York Giants football player. Died in September 2015 at age 27 of an apparent drug overdose; post­humously, determined to have Stage-2 CTE. His family reported memory loss, minor fits of rage, confusion, inattention, lack of focus, and chronic pain.

Sash’s mother said, “My son knew something was wrong, but he couldn’t express it. He was such a good person, and it’s sad that he struggled so with this—not knowing where to go with it. Now it makes sense.”¹⁰ Sash played 16 years of football in all, sustaining at least 5 concussions. (“If you’ve played football, you know there are often other incidents [of head trauma],” Sash’s father said.¹⁰)

Cultural and medical mindsets about contact sports
In the United States, children as young as age 5, with a low weight limit of 35 pounds, routinely are introduced to football.¹¹ Reports of 5 high school players dying from football-related injury in the 2014 season, and 3 deaths in the 2015 season, led a St. Louis, Missouri, area school district to defund their football program entirely. The district’s 2015 homecoming game was a soccer match; students and parents seemed to embrace the change.¹²

On its face, soccer seems a good alternative to football. When children are instructed to “head” the ball, however, concern arises about CTE: Mild CTE changes have been reported in 2 young soccer players, and late-stage CTE changes were seen in a retired soccer player with dementia.¹³

Perhaps most disturbing is that players who develop symptoms of CTE, or are at risk, are unlikely to seek psychiatric help. We, as psychiatric clinicians, must be diligent about questioning young patients about their extracurricular activities. It is not enough to simply ask about a history of head trauma: Ask patients about any blow to the head, and don’t limit your questioning to whether they sustained a “concussion” during practice or play.

When speaking with adult and geriatric patients, ask about a history of playing interscholastic or collegiate contact sports, such as football, hockey, and soccer.

Is the solution to better shield the head?
That is not a solution: Helmets and other protective headgear appear to be insufficient to protect the brain from traumatic injury. Perhaps keeping children from engaging in violent sports that put them at high risk of CTE later is the preventive approach that merits the most attention.
