Treatment of depressive symptoms in human immunodeficiency virus-positive patients.

BACKGROUND: This randomized clinical trial compared 16-week interventions with interpersonal psychotherapy, cognitive behavioral therapy, supportive psychotherapy, and supportive psychotherapy with imipramine for human immunodeficiency virus (HIV)-positive patients with depressive symptoms. METHODS: Subjects (N = 101; 85 male, 16 female) with known HIV seropositivity for at least 6 months were randomized to 16 weeks of treatment. Inclusion criteria were 24-item Hamilton Depression Rating Scale score of 15 or higher, clinical judgment of depression, and physical health sufficient to attend outpatient sessions. Therapists were trained in manualized therapies specific for HIV-positive patients. Treatment adherence was monitored. RESULTS: Subjects randomized to interpersonal psychotherapy (n = 24) and supportive psychotherapy with imipramine (n = 26) had significantly greater improvement on depressive measures than those receiving supportive psychotherapy (n = 24) or cognitive behavioral therapy (n = 27). Similar results appeared in the completer subsample. CONCLUSIONS: Depressive symptoms appear treatable in HIV-positive patients. Interpersonal psychotherapy may have particular advantages as a psychotherapy for patients who have experienced the significant life events of HIV infection.

The role of drug and alcohol abuse in recent increases in depression in the US.

Previous studies have reported an increase in depression among recent birth cohorts. Concurrent with the increase in rates of depression, there have been increases in rates of drug and alcohol abuse and dependence. This study sought to determine if the recent increase in rates of depression could be attributed to co-morbid alcohol and drug abuse. The data derived from two studies: (1) a sample of relatives of probands with affective disorder; and (2) a community survey of the US population. The piecewise exponential statistical model was applied to evaluate the association of gender, age, period and birth cohort with rates of major depressive disorder (MDD) separately for those with, and without, diagnoses of alcohol or drug abuse. Elevated rates of MDD occurred among those with co-morbid drug and alcohol abuse in both the family and community samples. However, there were also temporal increases in rates of MDD in those with no such co-morbidity. Specifically there were effects of age and gender for both studies; in addition, there was a period effect in the family study and a birth cohort effect in the community sample. The recent increases in depression in the US cannot be accounted for solely by concurrent increases in co-morbid drug and alcohol abuse. Temporal (period and cohort) effects on rates of depression occur in addition to the contribution of co-morbid drug and alcohol abuse or dependence.

Individual psychotherapies for depressed HIV-positive patients.

OBJECTIVE: The authors present preliminary data from two treatment modalities of a randomized clinical trial in which they compared 16-week interventions of interpersonal psychotherapy to supportive psychotherapy. METHOD: HIV-positive patients who were not acutely medically ill and had scores of 15 or higher on the Hamilton Depression Rating Scale were randomly assigned to one of four treatment modalities. They were assessed by the Hamilton scale and Beck Depression Inventory at 8 and 16 weeks. Most subjects who underwent either interpersonal psychotherapy (N = 16) or supportive psychotherapy (N = 16) were male, gay or bisexual, white, and college educated. RESULTS: Results of last-observation-carried-forward and completer analyses showed that scores on the Hamilton scale and Beck Depression Inventory decreased significantly for both treatments. Differential improvement for interpersonal psychotherapy appeared by midtreatment (week 8) and persisted at termination. CONCLUSIONS: This is the first controlled study of individual psychotherapies for depressed HIV-positive patients. Results suggest that a specific antidepressant psychotherapy, interpersonal psychotherapy, has advantages over a supportive therapy.

Long-term follow-up after a drug trial for panic disorder.

BACKGROUND: This study investigates the naturalistic course of panic disorder over four years and attempts to identify predictors for outcome. METHOD: 423 DSM-III-R panic disorder patients who had taken part in an international multicentre drug trial were selected for follow-up; we were able to re-interview 367 (87%). For panic attacks, phobic avoidance and disabilities the same rating scales were administered as had been used for the clinical trials. RESULTS: While 61% of all patients experienced at least occasional panic attacks at follow-up, few suffered from serious phobic avoidance (16.7%) or serious disabilities (work 7.9%); family 8.7%; social 13.9%). Panic attack frequency at baseline, original trial medication and continuous use of psychotropic medication during follow-up are not related to outcome, whereas longer duration of illness and more severe phobic avoidance at baseline are unfavourable. CONCLUSION: The course of panic disorder is not uniform. Since long duration of illness and severe phobic avoidance at baseline are predictors for an unfavourable outcome, more rigorous efforts should be undertaken to detect and treat panic disorder at an early stage.

What are the public health implications of subclinical depressive symptoms?

Longitudinal data from a community study of 9900 adults in the United States show that persons with depressive symptoms, as compared to those without such symptoms, were 4.4 times more likely to develop a first onset major depression over one year. The attributable risk, a measure which reflects both the relative risk associated with depressive symptoms (4.4) and the prevalence of exposure to that risk (24%) and is a useful measure for documenting burden of a risk to the community, indicated that more than 50% of first onset major depressions are associated with prior depressive symptoms. Since depressive symptoms have a high prevalence in the community, but are often unrecognized and untreated in clinical practice, we conclude that their identification and the development of effective treatments could have public health implications for the prevention of associated social morbidity, service utilization and major depression.

A comparison of symptom determinants of patient and clinician global ratings in patients with panic disorder and depression.

The Clinical Global Impression (CGI) is a standard assessment tool that generally shows good sensitivity to change in psychopharmacology trials. However, systematic assessment has not been conducted to determine how rating decisions are made. In this article, we examine the relationship between syndromal symptomatology and the CGI severity and improvement ratings in a study of 116 patients who met DSM-III-R criteria for both Panic Disorder and Depression. Anticipatory anxiety and depression ratings were significantly associated with each CGI item. Frequency of panic attacks was consistently related to the clinician's rating of severity but was only sporadically related to the clinician and patient improvement ratings. These findings are fairly consistent during the course of treatment. Our empirical examination of symptom determinants of the CGI demonstrates that it appears to be used systematically, yet global ratings are not merely a composite of symptomatology. Its widespread application in clinical trials is well justified.

A psychodynamic model of panic disorder.

Current psychiatric research on panic disorder and its treatment are heavily influenced by neurobiological and cognitive-behavioral models rather than psychodynamic propositions, and psychodynamic treatment is generally considered to be of little benefit in amelioration of symptoms. However, because neither of the current models fully explains the clinical psychopathology, etiology, or pathogenesis of panic disorder, there is a need for further model building. The authors suggest that a psychodynamic approach may add to the understanding of patients with panic disorder. They base their psychodynamic formulation on pilot interviews with nine patients with panic disorder, published reports of psychological characteristics of patients with panic disorder, and data from infant and animal research on temperament. Interview results included the following: 1) all of the patients described themselves as fearful, nervous, or shy as children, 2) they remembered their parents as angry, frightening, critical, or controlling, 3) they frequently indicated discomfort with aggression, 4) most described chronic feelings of low self-esteem, 5) their spouses were characterized as passive, kind, and nonaggressive, and 6) stressors associated with frustration and resentment preceded the onset of panic. The authors propose a model in which inborn neurophysiological irritability predisposes to early fearfulness. Exposure to parental behaviors that augment fearfulness results in disturbances in object relations and persistence of conflicts between dependence and independence, which predispose to fears of feeling trapped, suffocated, and unable to escape and/or feeling alone and unable to get help. Catastrophic fears of helplessness in the face of suffocation or abandonment are easily accessible.(ABSTRACT TRUNCATED AT 250 WORDS)

The enduring psychosocial consequences of mania and depression.

OBJECTIVE: The authors sought to determine the scope, severity, and persistence of psychosocial impairment arising from bipolar and unipolar affective disorder. METHOD: Patients with bipolar (N = 148) or unipolar (N = 240) major affective disorder were assessed as they sought treatment and again after a 5-year follow-up. Concurrently, parents, siblings, and adult children underwent similar assessments and were followed for 6 years. To quantify the impact of affective disorder, probands were individually matched to relatives who had no lifetime history of affective disorder. Sixty-nine relatives who were depressed at intake constituted a separate, nonclinical study group and were also matched to relatives who were well. RESULTS: Both unipolar and bipolar patients began follow-up with deficits in annual income. Relative to comparison subjects, affective disorder groups were significantly more likely to report declines in job status and income at the end of follow-up and significantly less likely to report improvements. Similarly, both bipolar and unipolar patients showed significant deficits in nearly all other areas of psychosocial functioning measured at follow-up. Except for relationships with spouses, deficits did not differ significantly by polarity. Surprisingly, probands with recovery sustained throughout the final 2 years of follow-up also showed severe and widespread impairment. Relatives with major depression exhibited substantial deficits on follow-up, but job status and income were not significantly affected. CONCLUSIONS: The psychosocial impairment associated with mania and major depression extends to essentially all areas of functioning and persists for years, even among individuals who experience sustained resolution of clinical symptoms.

Continuing female predominance in depressive illness.

This paper examines gender differences in temporal trends for major depressive disorder in childhood, adolescence, and young adulthood. The study sample, a high-risk group from the National Institute of Mental Health Collaborative Study on the Psychobiology of Depression, includes 2000 first-degree relatives of probands with affective disorder. The age-specific incidence rates were analyzed to determine the effect of gender, age, period, and cohort on depression by age 35. Women had nearly a twofold increase in risk of major depressive disorder, with rates peaking between adolescence and early adulthood. Vulnerability to depression was highest in the 1960s and 1970s. The rate increase in recent decades has not corresponded to a reduction in the gender differences.

Trends in the prescription of antidepressants by office-based psychiatrists.

OBJECTIVE: This study was done in an effort to determine whether there was a change over the past decade in the number and proportion of patients prescribed antidepressants by psychiatrists in private practice. METHOD: The authors analyzed data from the National Ambulatory Medical Care Survey for the years 1980, 1985, and 1989, focusing on visits by adults over the age of 18 years to physicians specializing in psychiatry and psychiatric subspecialties. RESULTS: The number of visits that included prescribing an antidepressant medication grew from approximately 2.5 million in 1980 to 4.7 million in 1989, or from 17.9% to 30.4% of all office-based psychiatric visits. Fluoxetine, which first became available in 1988, accounted for 29.6% of the prescriptions for antidepressants in 1989. Increases in prescriptions for antidepressants were particularly evident for male patients, young adult patients, and patients with neurotic disorders. CONCLUSIONS: There was an increase in the 1980s in the use of antidepressants in office-based psychiatric practice. The advent of new agents and the broadening of the clinical usefulness of existing agents may have contributed to this increase.

The roles of psychiatrists in organized outpatient mental health settings.

OBJECTIVE: This paper describes the clinical roles of psychiatrists in U.S. organized outpatient mental health settings. METHOD: Data were analyzed from the 1986 National Institute of Mental Health Client/Patient Sample Survey. The authors determined the range, volume, and content of services provided to established outpatients treated by psychiatrists at six types of mental health organizations: state and county mental hospital clinics, general hospital mental health clinics, private psychiatric hospital clinics, U.S. Department of Veterans Affairs medical center mental health clinics, free-standing mental health clinics, and multiservice mental health organizations. RESULTS: The psychiatrists treated nearly one-half (48.2%) of the established outpatients in organized settings, more than any other discipline. Most of the psychiatrists' patients (68.3%) were also treated by other mental health professionals. Psychiatrists treated a greater proportion of the patients at hospital-based clinics (60.7%) than at clinics without hospital affiliations (43.6%). They also treated larger proportions of the patients with schizophrenia (77.9%), affective disorders (50.6%), or anxiety disorders (59.2%) than those with adjustment disorders (23.7%), substance use disorders (34.3%), or childhood mental disorders (29.5%). The patients treated by psychiatrists commonly received psychotropic medications (77.3%) and individual therapy (66.3%) but less commonly received group (20.7%), skills (11.9%), or family (5.9%) therapy. CONCLUSIONS: In organized outpatient settings, psychiatrists typically work with other mental health professionals to treat a select group of severely ill patients. However, there is considerable variation in the extent to which different types of mental health organizations rely on psychiatrists to provide clinical care.

The course of transient hypochondriasis.

OBJECTIVE: This study examined the longitudinal course of patients known to have had a previous episode of transient hypochondriasis. METHOD: Twenty-two transiently hypochondriacal patients and 24 nonhypochondriacal patients from the same general medical clinic were reexamined after an average of 22 months with the use of self-report questionnaires, structured diagnostic interviews, and medical record review. RESULTS: The hypochondriacal patients continued to manifest significantly more hypochondriacal symptoms, more somatization, and more psychopathological symptoms at follow-up. They also reported significantly more amplification of bodily sensations and more functional disability and utilized more medical care. These differences persisted after control for differences in medical morbidity and marital status. Only one hypochondriacal patient, however, had a DSM-III-R diagnosis of hypochondriasis at follow-up. Multivariate analyses revealed that the only significant predictors of hypochondriacal symptoms at follow-up were hypochondriacal symptoms and the tendency to amplify bodily sensations at the baseline evaluation. CONCLUSIONS: Hypochondriacal symptoms appear to have some temporal stability: patients who experienced hypochondriacal episodes at the beginning of the study were significantly more hypochondriacal 2 years later than comparison patients. They were not, however, any more likely to develop DSM-III-R-defined hypochondriasis. Thus, hypochondriacal symptoms may be distinct from the axis I disorder. The data are also compatible with the hypothesis that preexisting amplification of bodily sensations is an important predictor of subsequent hypochondriacal symptoms.

Suicidal children grow up: rates and psychosocial risk factors for suicide attempts during follow-up.

OBJECTIVE: Rates and psychosocial risk factors for suicide attempts during a 6 to 8-year follow-up period were compared for 25 predominantly prepubertal inpatient suicide attempters, 28 inpatient suicidal ideators, 16 nonsuicidal inpatients, and 64 nonpatients. METHOD: Standard research instruments were used to interview subjects and parents. Cox proportional hazard regression analyses were used to identify risk factors for a suicide attempt in the follow-up. RESULTS: No deaths occurred during follow-up. Suicide attempters were six times and suicidal ideators were three times more likely than were nonpatients to attempt suicide during follow-up. Poor social adjustment and mood disorder close to a recurrent suicide attempt were the strongest risk factors. CONCLUSIONS: Risk assessment should focus on identifying symptoms of mood disorders and impaired social adjustment in children with histories of suicide attempts and psychiatric hospitalization.

Effect size as a measure of symptom-specific drug change in clinical trials.

A data-analytic strategy is proposed for identifying the symptom-specific effects of each medication in a clinical trial. The within-group effect size is a standardized ratio of the pre-post change relative to the stability of change for each treatment group. Advantages of using this descriptive approach are illustrated by examining antidepressant effects of alprazolam, imipramine, and placebo in a clinical trial for patients meeting criteria for both panic disorder and depression. There was a significant difference between active medication and placebo on the Hamilton Rating Scale for Depression (HAM-D) total, but no difference between the anti-depressant effects of the active medications despite their diverse psychopharmacologic properties. Examination of effect sizes for each HAM-D item revealed distinct symptom-specific effects of each active medication in this study sample. Although these descriptive findings cannot be used for inferential conclusions, they can be used to guide the design of future trials.

The treatment of depression: prescribing practices of primary care physicians and psychiatrists.

BACKGROUND: Depression is one of the most common mental disorders treated by primary care physicians. Concern has been expressed that primary care physicians underutilize antidepressants and overutilize anxiolytics in their management of depressive disorders. METHODS: Data from the 1980, 1985, and 1989 National Ambulatory Medical Care Surveys were used to examine the pharmacologic treatment provided by primary care physicians and psychiatrists during office visits with patients diagnosed as depressed. The number and proportion of these visits that included an antidepressant prescription or an anxiolytic prescription were determined. RESULTS: Primary care physicians and psychiatrists both prescribed antidepressants more commonly than other classes of psychotropic medications during visits that included a depression diagnosis. Compared with psychiatrists, primary care physicians more commonly prescribed antidepressants for depressive disorders (1980, 55% vs 33%; 1985, 59% vs 41%; 1989, 57% vs 45%). In 1989, benzodiazepines were prescribed in 16% of the primary care visits for depression. More than half of these visits (56%) also resulted in an antidepressant being prescribed. Primary care visits for depression tended to be slightly longer than other primary care visits, but only about half as long as patient visits with psychiatrists. CONCLUSIONS: The pharmacologic treatment of depression by primary care physicians may be better focused than previously assumed. Future research should examine the informal psychological treatment routinely provided by primary care physicians to patients with depressive disorders.

Depressive symptoms as relative and attributable risk factors for first-onset major depression.

Using longitudinal data from a community study of 9900 adults drawn from four sites in the United States and interviewed twice, 1 year apart, we investigated the predictors of first-onset major depression. Using odds ratios to estimate relative risk, we found that persons with depressive symptoms, compared with those without such symptoms, were 4.4 times more likely and persons with dysthymia were 5.5 times more likely to develop a first-onset major depression during a 1-year period. The lifetime prevalence rate for depressive symptoms was 24%. The attributable risk is a compound epidemiologic measure that reflects both the relative risk associated with depressive symptoms (4.4) and the prevalence of exposure to that risk (24%). It is a useful measure to document the burden of a risk to the community, and it was determined to be greater than 50%. Thus, more than 50% of cases of first-onset major depression are associated with prior depressive symptoms. The high prevalence of depressive symptoms in the community and their strong association with first-onset major depression make them important from a public health perspective. Because depressive symptoms are often unrecognized and untreated in clinical practice, we conclude that their identification and the development of effective treatments could have implications for the prevention of major depression.
