Secondary depression in panic disorder and agoraphobia. II. Dimensions of depressive symptomatology and their response to treatment.

Secondary depressive symptomatology in 435 subjects with panic disorder and phobic avoidance was studied before and after alprazolam treatment. No subject who had a primary affective disorder was included. Calculation of Hamilton Depression Rating Scale factor scores revealed that the agitation/anxiety, sleep disturbance, and somatization factors accounted for approximately 75% of the HAM-D total score; these all showed significant improvement with alprazolam treatment. There were few differences in dimensions of depressive symptomatology between those subjects with and those without major depression; the main difference was in the overall intensity of the depression.

Follow-up study of patients with panic disorder and agoraphobia with panic attacks treated with tricyclic antidepressants.

One hundred and seven patients with panic disorder or agoraphobia with panic attacks were studied 1-4 years after treatment with a tricyclic antidepressant. At follow-up more than 80% of the patients remained symptomatic but fewer than half were experiencing panic attacks and only 40% were avoiding phobic situations. Although patients with agoraphobia were more severely ill and had been ill longer than those with panic disorder, their response to tricyclics and eventual outcome was similar to that for patients with panic disorder. Panic and agoraphobic patients who had the most severe symptoms initially showed the least improvement. The results suggest that panic disorder and agoraphobia with panic attacks are variants of a single illness and that, despite its chronicity, this illness has a favorable outcome.

Suicide and panic disorder: a review.

This article reviews the risk of suicide in panic disorder beginning with early studies showing increased mortality, including suicide, among patients belonging to the broad category of neuroses. More recent follow-up studies of patients with anxiety disorders have found about 20% of deaths due to suicide, a proportion similar to that found in depressive disorders. Also, suicide attempts have been reported by similar proportions of subjects with panic disorder and major depression from the general population. Preliminary data indicate that more severely ill patients with coexisting depression and substance abuse are more likely to attempt or complete suicide. Thus, although limited, the data indicate that the risk of suicide in panic disorder is substantial. As a consequence, clinicians should alert themselves to this preventable outcome and approach treatment with added caution.

Imipramine an effective treatment for illness phobia.

Ten subjects with illness phobia were treated with imipramine for 8 weeks. All of the eight subjects who remained on the drug for 4 weeks or more reported at least moderate improvement. Overstimulatory reactions occurred in four subjects causing two to discontinue medication. Imipramine appears to be a potentially useful treatment for this subtype of hypochondriasis.

Rapid relief of anxiety in cancer patients with both alprazolam and placebo.

This study evaluated 36 cancer patients who were enrolled in a randomized, double-blind, placebo-controlled trial conducted over a 4-week period to evaluate the efficacy of alprazolam in the treatment of anxiety associated with cancer. Hamilton Anxiety Scale scores declined significantly between baseline and the end of the first week of the study in both treatment groups. There was no significant difference in response between the patients receiving alprazolam and placebo. Similar results were obtained from other instruments. These results suggest that nondrug factors or spontaneous improvement may play a more important role than pharmacotherapy in the treatment of anxiety associated with cancer.

One-year follow-up of medical outpatients with hypochondriasis.

To examine the diagnostic stability and outcome of hypochondriasis, the authors followed 50 patients with this disorder and 50 age- and sex-matched control subjects after 1 year. After 1 year, two-thirds of the subjects continued to meet criteria for hypochondriasis, and the remaining third had persisting hypochondriacal symptoms. The hypochondriacal subjects were improved on most measures but still differed from the control subjects with regard to attitudes, perceptions, and behaviors that had distinguished them initially. More severe symptoms, longer duration of illness, and coexisting psychiatric illness were predictive of a worse outcome. The data indicate that the diagnosis of hypochondriasis is stable over time, and that, although symptoms wax and wane, characteristic features persist. The findings underscore the importance of diagnosing and treating hypochondriasis in medical outpatients.

Fellowship training in consultation-liaison psychiatry. Education goals and standards.

Consultation-liaison (C-L) psychiatry, which focuses on the psychiatric care of patients in medical-surgical settings, has evolved into an increasingly recognized subspecialty. The Academy of Psychosomatic Medicine, using consultants and a database created from 49 extant C-L fellowship programs, has specified goals and standards for C-L fellowship training. These standards include organizational issues, clinical skills, a didactic curriculum, research training, and evaluation issues. The important contributions of C-L psychiatry to medical education are emphasized.

The relationship between irritable bowel syndrome and psychiatric illness. A family study.

Although irritable bowel syndrome (IBS) is a common disorder among gastrointestinal clinic outpatients, it continues to be a diagnosis of exclusion. In treatment-seeking populations, IBS has been frequently associated with psychiatric illness, and this co-occurrence has added to controversy about the validity of the IBS diagnosis. This study is a preliminary effort to examine the nature of this relationship by using the family study design. The probands consisted of 20 patients with IBS and 20 patients who had undergone laproscopic cholecystectomy. Their first-degree relatives were interviewed to obtain lifetime diagnoses of functional gastrointestinal and psychiatric syndromes. Significantly more IBS probands had lifetime psychiatric illness than the cholecystectomy probands. The lifetime prevalence of IBS as well as other functional gastrointestinal syndromes was not significantly different between the groups of relatives. However, significantly more relatives of the IBS probands had lifetime psychiatric illness than the relatives of the cholecystectomy probands. Among the relatives with functional gastrointestinal disorders, significantly more had psychiatric illness. This preliminary study provides support for a relationship between IBS and psychiatric illness by the finding of an increased prevalence of psychiatric disorders among the relatives of patients who have IBS.

Correlates of hypochondriasis in a nonclinical population.

Because few community surveys of hypochondriasis have been completed, little is known about the epidemiology of this disorder outside of clinical populations. To address this deficiency, the authors obtained information about hypochondriasis and pertinent characteristics from a group of first-degree relatives of hypochondriacal and nonhypochondriacal probands who participated in a family study. In addition to psychiatric diagnoses, the authors elicited information on demographic variables, medical history, impairment in functioning, psychiatric comorbidity, psychiatric symptoms, personality traits, and childhood experiences. The authors identified hypochondriasis in 7.7% of the relatives. These relatives had a high rate of comorbid anxiety, depressive, and somatoform disorders. They also reported substantial physical and psychological impairment, including diminished work performance and disability. In addition, these relatives reported greater utilization of health care but less satisfaction with that care. These relatives showed most of the same characteristics found in earlier studies of hypochondriacal patients.

Health Attitude Survey. A scale for assessing somatizing patients.

The authors designed an instrument, the Health Attitude Survey, to assess somatization, and administered it to over 1,000 patients attending a general medicine clinic. Within this population, a series of somatizing patients and control patients were identified for purposes of developing and testing the instrument. The 27-item scale was rapidly administered and acceptable to the patients. Based on comparisons with other measures of somatization, the instrument appeared to be a valid measure of the attitudes and perceptions of somatizing patients, and it distinguished these patients from the control subjects. The measure showed acceptable predictive value and may prove useful in clinical settings, where rapid screening is desired.

Attachment and interpersonal communication in somatization.

The authors review the research on childhood antecedents and personality contributions to the somatoform disorders, as well as research on social influences during adulthood. Based on these data, the authors hypothesize that somatizing patients display anxious attachment behavior that derives from childhood experiences with caregivers. Early exposure to illness increases the likelihood that distress will be manifested somatically. When under stress as adults, somatizers use physical complaints to elicit care. Somatizers' interpersonal interactions with others, including physicians, ultimately lead to rejection that reinforces the somatizer's belief that he or she will be abandoned. Modification of physicians' responses to these patients may improve treatment outcomes.

Unexplained symptoms in primary care: perspectives of doctors and patients.

This study evaluated unexplained symptoms in primary care from the perspective of both patients and physicians. The data were obtained from two 1998 statewide surveys, one targeting Medicaid patients and the other all primary care physicians in the state. There were 439 patients who responded (45% response rate) and 280 primary care physicians who responded (33% response rate). Half of the patients and half of the physicians were in non-metropolitan counties. Half of the patients reported unexplained symptom usually or always, and 75% of whom sought help for these symptoms. Fifty-two percent of these patients believed their physician was very concerned about their unexplained symptoms. Eighty percent of them rated their physician as providing the best possible care compared to only 49% of patients whose physician did not care about their unexplained symptoms (P=.001). Among the physicians, only 14% reported very good or excellent satisfaction with managing unexplained symptoms as compared to 44% who claimed similar satisfaction in managing psychological problems. Physicians who saw themselves as more effective in dealing with somatoform symptoms were more likely to be in solo practice (P<.005), or in the same location for at least five years (P=.04). Residence in a nonmetropolitan county did not affect patient reporting of symptoms, patient perception of physician concern about symptoms, or physician satisfaction in managing these symptoms. These results indicate the prevalence and importance of unexplained symptoms in the Medicaid population and the comfort of physicians in managing these symptoms. There is an unmet need among primary care physicians to learn how to manage patients with unexplained symptoms.

The relationship of hypochondriasis to anxiety disorders.

There is evidence from the literature of phenomenological overlap between hypochondriasis and several anxiety disorders, including specific phobia, panic disorder with agoraphobia, generalized anxiety disorder, and obsessive-compulsive disorder. Even though the boundaries of these disorders are specifically addressed in the DSM-IV criteria, there is evidence of anxiety and phobic symptoms among hypochondriacal patients and hypochondriacal concerns among patients with these various anxiety disorders. Beyond that there appears to be considerable shared comorbidity. However, the data remain limited and few direct comparisons have been made between hypochondriacal and anxious patients belonging to particular diagnostic categories. Subtypes of hypochondriasis may exist. In fact, the clearest link would seem to be between the illness phobia subtype and other phobic disorders, although this subgroup has had little study. Thus, hypochondriasis is distinct from the anxiety disorders but, because of phenomenological similarities and extensive comorbidity, consideration should be given to classifying it among them.

Illness fears in the general population.

OBJECTIVES: Because relatively little is known about illness fears, we sought to estimate the prevalence, risk factors, and morbidity associated with such fears in the community. METHODS: We conducted a brief telephone survey of persons aged 40 to 65 years from randomly selected households in the Johnson County, Iowa, area. Respondents were asked whether a series of illness and medical care items made them no more nervous, somewhat more nervous, or much more nervous than other people. Those who reported more discomfort were asked to what extent this interfered with medical care or caused impairment or distress. Information about demographic and health characteristics was also obtained. RESULTS: Five hundred persons, 62% of those contacted, responded to the survey. A factor analysis revealed four fear dimensions: illness/injury, medical care, blood/needle, and aging/death. Five percent of respondents reported much more nervousness in relation to at least four of six illness/injury items, 4% indicated that such fears interfered with their medical care, and 5% reported some negative effect on their life. Similarly, 5% of respondents reported much more nervousness in relation to at least two of four medical care items. Illness/injury fears were somewhat more common in persons with lower income and education and in those with medical conditions. CONCLUSIONS: This survey shows that fears of illness and medical care are common in the general population and indicates that lower socioeconomic status and experience with illness are associated with these fears. The findings also suggest that interference with care occurs among those with the strongest fears.

Personality dysfunction among somatizing patients.

To examine the nature and extent of personality dysfunction related to somatization, the authors administered the Structured Interview for DSM-IV Personality and the NEO Five-Factor Inventory to a series of somatizing and nonsomatizing patients in a general medicine clinic. A greater percentage of somatizers met criteria for one or more DSM-IV personality disorders, especially obsessive-compulsive disorder, than did control patients. Somatizers also differed from control patients with respect to self-defeating, depressive, and negativistic personality traits and scored higher on the dimension of neuroticism and lower on the dimension of agreeableness. In addition, initial and facultative somatizers showed more personality pathology than true somatizers. These findings suggest that certain personality disorders and traits contribute to somatization by way of increased symptom reporting and care-seeking behavior.
