Psychopathological characteristics of recovered bulimics who have a history of physical or sexual abuse.

We sought to clarify the influence of a history of sexual or physical abuse on a variety of psychopathologies in subjects with bulimia nervosa (BN). To avoid confounding effects, the presence of a history of sexual or physical abuse, lifetime axis I disorders, and personality disorders were assessed through direct structured interviews in 44 subjects recovered from BN for at least 1 year. Twenty abused subjects (45%) were significantly more likely than 24 subjects without abuse to have severe general psychopathology and eating disturbance. Compared with nonabused subjects, abused subjects showed a trend toward more frequent lifetime diagnoses of posttraumatic stress disorder and substance dependence. These results suggest that abusive experiences may be associated with some psychopathology of BN, particularly related to anxiety, substance abuse, and more severe core eating disorder pathology.

Obsessive-compulsive disorder symptoms before and after recovery from bulimia nervosa.

OBJECTIVE: Obsessive-compulsive disorder (OCD) symptoms are common in people who are ill with bulimia nervosa. However, little is known about whether OCD symptoms persist after long-term recovery from bulimia. METHOD: Thirty-one female patients with bulimia nervosa, 29 women who had been recovered from bulimia for more than 1 year, and 19 healthy female comparison subjects completed the Yale-Brown Obsessive Compulsive Scale, which measures OCD-like symptoms. Items related to symptoms of core eating disorders were omitted from the Yale-Brown scale. RESULTS: The Yale-Brown scale scores of the women with bulimia (mean = 13.1, SD = 10.6) and those who had recovered from bulimia (mean = 7.9, SD = 7.0) were significantly higher than the scores of the normal comparison subjects (mean = 1.9, SD = 2.6). Women with bulimia and those who had recovered from bulimia had similar Yale-Brown scale scores and endorsed similar Yale-Brown scale target symptoms, such as obsessions related to symmetry and exactness. CONCLUSIONS: OCD symptoms persist after recovery from bulimia. Moreover, the types of OCD symptoms experienced by bulimia patients do not vary dramatically with improvement in bulimic symptoms. Persistent OCD symptoms after recovery from bulimia raise the possibility that these behaviors are trait-related and contribute to the pathogenesis of bulimia.

Alterations in serotonin activity and psychiatric symptoms after recovery from bulimia nervosa.

BACKGROUND: Women with bulimia nervosa (BN) have disturbances of mood and behavior and alterations of monoamine activity when they are bingeing and purging. It is not known whether these alterations are secondary to pathological eating behavior or traits that could contribute to the pathogenesis of BN. METHODS: To avoid the confounding effects of pathological eating behavior, we studied 30 women after long-term recovery (>1 year with no bingeing or purging, normal weight, and regular menstrual cycles) from BN. Subjects were compared with 31 healthy volunteer women. We assessed psychiatric diagnoses and symptoms to determine whether there was any persistent disturbance of behavior after recovery. We measured cerebrospinal fluid (CSF) levels of the major metabolites of serotonin (5-hydroxyindoleacetic acid [5-HIAA]), dopamine (homovanillic acid [HVA]), and norepinephrine (3-methoxy-4-hydroxyphenylglycol [MHPG]) as well as hormonal and behavioral response to m-chlorophenylpiperazine (m-CPP), a serotonin-specific agent. RESULTS: Women who were recovered from BN had mild to moderate negative moods and obsessions with perfectionism and exactness and exaggerated core eating disorder symptoms compared with healthy volunteer women. Recovered BN women had increased levels of CSF 5-HIAA compared with control women (117 +/- 33 vs 73 +/- 15 pmol/mL; P< or =.001) but normal CSF HVA and MHPG concentrations. Recovered BN women had an anxious and disorganized behavioral response to m-CPP but a normal hormonal response. CONCLUSIONS: Persistent serotonergic and behavioral abnormalities after recovery raise the possibility that these psychobiological alterations might be trait-related and contribute to the pathogenesis of BN.

A controlled family study of anorexia nervosa and bulimia nervosa: psychiatric disorders in first-degree relatives and effects of proband comorbidity.

BACKGROUND: We used contemporary family-epidemiological methods to examine patterns of comorbidity and familial aggregation of psychiatric disorders for anorexia and bulimia nervosa. METHODS: Direct interviews and blind best-estimate diagnostic procedures were used with diagnostically "pure" groups of probands with eating disorders and a matched control group. Lifetime prevalence rates of eating disorders, mood disorders, substance use disorders, anxiety disorders, and selected personality disorders were determined in female probands with restricting anorexia nervosa (n=26) or bulimia nervosa (n=47), control women (n=44), and first-degree biological relatives (n=460). RESULTS: Relatives of anorexic and bulimic probands had increased risk of clinically subthreshold forms of an eating disorder, major depressive disorder, and obsessive-compulsive disorder. Familial aggregation of major depressive disorder and obsessive-compulsive disorder was independent of that of anorexia nervosa and bulimia nervosa. These relatives also had increased risk of other anxiety disorders, but the mode of familial transmission was not clear-cut. The risk of substance dependence was elevated among relatives of bulimic probands compared with relatives of anorexic probands, and familial aggregation was independent of that of bulimia nervosa. The risk of obsessive-compulsive personality disorder was elevated only among relatives of anorexic probands, and there was evidence that these 2 disorders may have shared familial risk factors. CONCLUSIONS: There may be a common familial vulnerability for anorexia nervosa and bulimia nervosa. Major depressive disorder, obsessive-compulsive disorder, and substance dependence are not likely to share a common cause with eating disorders. However, obsessional personality traits may be a specific familial risk factor for anorexia nervosa.

The role of the central nervous system in the psychoneuroendocrine disturbances of anorexia and bulimia nervosa.

It has been well-recognized that starvation in anorexia and bulimia nervosa causes endocrine disturbances. Such disturbances may help understand why many people with eating disorders cannot easily reverse their illness since people with eating disorders often enter a downward spiraling circle with malnutrition sustaining and perpetuating the desire for more weight loss and dieting. Symptoms, such as obsessions and dysphoric mood, and altered appetitive behavior, may be exaggerated by neuropeptide alterations and thus contribute to this downward spiral. While neuropeptide disturbances do not appear to be a permanent feature or cause or anorexia nervosa, these disturbances are strongly entrenched, and are not easily corrected by improved nutrition or short-term weight normalization. This suggests that therapy should be sustained for months after nutritional normalization.

Relationship of depression, anxiety, and obsessionality to state of illness in anorexia nervosa.

OBJECTIVE: Depression, anxiety, and obsessionality frequently are present in underweight, malnourished patients with anorexia nervosa. It is less certain if these symptoms persist after recovery. Thus, we assessed these symptoms in anorexic women at three states of illness (underweight, short-term weight restored, and long-term weight restored) in comparison to a group of healthy women. METHOD: We used standardized self- and trained rater instruments to assess depression (Hamilton Depression Rating Scale and Beck Depression Inventory), anxiety (Spielberger State-Trait Anxiety Inventory and Hamilton Anxiety Rating Scale), and obsessions and compulsions (Yale-Brown Obsessive Compulsive Scale). RESULTS: A similar pattern was found for all symptoms. That is; scores for depression, anxiety, and obsessionality were most elevated in the underweight state. These symptoms improved with weight restoration. However, milder but significantly elevated symptoms persisted in long-term weight-restored anorexic women compared to healthy control women. DISCUSSION: These data suggest that malnutrition intensifies the severity of depression, anxiety, and obsessionality in anorexia nervosa. However, the fact that mild to moderate symptoms persisted after long-term weight restoration raises the possibility that such behaviors are related to the pathogenesis of this illness.

Psychiatric disorders in women with bulimia nervosa and their first-degree relatives: effects of comorbid substance dependence.

OBJECTIVE: Women with bulimia nervosa (BN) and comorbid substance dependence often display impulsive behaviors. We assessed Axis I and II psychiatric diagnoses in their first-degree relatives in order to understand the etiological factors that may contribute to this subtype of BN. METHOD: We used contemporary family-epidemiological methodology to compare the lifetime prevalence of psychiatric disorders among 47 women with BN and 44 non-eating-disordered community control women, and their first-degree relatives (177 and 190, respectively). BN probands were stratified by the presence (n = 20) or absence (n = 27) of a lifetime history of alcohol and/or drug dependence. RESULTS: Social phobia, conduct disorder, and clusters B and C personality disorders were significantly more prevalent among BN probands with substance dependence than among BN probands without substance dependence or control women probands. Substance use disorders, social phobia, panic disorder, and cluster B personality disorders were significantly more prevalent among the relatives of BN probands with substance dependence than the relatives of the other two groups. DISCUSSION: Women with BN and substance dependence have problems with social anxiety, antisocial behavior, and a variety of personality disturbances, and come from families where there are problems with substance use disorders, anxiety, impulsivity, and affective instability. These data raise the possibility that a familial vulnerability for impulsivity and affective instability may contribute to the development of substance dependence in a subgroup of women with BN.

A comparison of subgroups of inpatients with anorexia nervosa.

OBJECTIVE: Classification of subgroups of people with anorexia nervosa has been in flux. It has not been clear whether anorexics who only purge should be grouped with pure restricters or with people who both binge and purge. METHODS: We compared 27 restricting-type anorexics (RAN), 26 bulimic anorexics (BAN), and 34 restricting anorexics with purging behaviors (RAN-P). All subjects were underweight and recently admitted to a hospital. We excluded subjects who had not had a diagnosis of anorexia nervosa for at least 1 year duration. RESULTS: The three groups of subjects had similar scores for Depression and Anxiety on the Beck Depression Inventory, the Spielberger State and Trait Anxiety Inventory, and on the EDI subscales aside from higher scores for BAN subjects on the Bulimia subscale. DISCUSSION: These three subgroups of anorexia nervosa have similar degrees of dysphoric moods and core eating disorder symptoms when underweight and malnourished.

Colonic and anorectal function in constipated patients with anorexia nervosa.

OBJECTIVES: Many patients with eating disorders complain of severe constipation. Previous studies have suggested that constipation in patients with anorexia nervosa may be associated with slow colonic transit. However, it is unclear whether a refeeding program will alter colonic transit in these patients. The aim of this study was to investigate colorectal function by measuring colonic transit and anorectal function in anorexic patients with constipation during treatment with a refeeding program. METHODS: We prospectively studied 13 female patients with anorexia nervosa who were admitted to an inpatient treatment unit and compared them to 20 previously studied, age-matched, healthy female control subjects. Patients underwent colonic transit studies using a radiopaque marker technique and anorectal manometry measuring anal sphincter function, rectal sensation, expulsion dynamics, and rectal compliance. Patients were studied both early (< 3 wk) and late (> 3 wk) in their admission. We restudied two patients who had slow colonic transit. All patients also underwent structured interviews. RESULTS: Four of six patients studied within the first 3 wk of their admission had slow colonic transit, defined as > 70 h (108.0 +/- 17.0 h, mean +/- SEM), on initial evaluation. In contrast, none of the seven patients studied later than 3 wk into their admission had slow colonic transit. Two of the four patients with slow transit were restudied later in their admission and were found to have normal transit times. Rectal sensation, internal anal sphincter relaxation threshold, rectal compliance, sphincter pressures, and expulsion pattern were normal in all subjects. CONCLUSIONS: Despite complaints of severe constipation, colonic transit is normal or returns to normal in the majority of patients with anorexia nervosa once they are consuming a balanced weight gain or weight maintenance diet for at least 3 wk.

Anorexia nervosa, obsessional behavior, and serotonin.

Although many women diet, relatively few develop the extreme weight loss and the clinical symptoms of anorexia nervosa. An underlying biological diathesis and temperament may place someone at risk for developing anorexia nervosa. Certain traits, such as negative affect, behavioral inhibition, compliance, high harm avoidance, and an obsessive concern with symmetry, exactness, and perfectionism, persist after recovery from anorexia nervosa. These persistent symptoms raise the possibility that such traits exist premorbidly and contribute to the pathogenesis of this disorder. Such traits could be associated with increased brain serotonin activity. After recovery, anorexics have increased levels of 5-HIAA, the major metabolite of serotonin, in the cerebrospinal fluid (CSF). Low CSF 5-HIAA levels have been associated with impulsive and aggressive behaviors, which are opposite to those typically found in anorexia nervosa. Increased serotonin activity could contribute to many behavioral symptoms, such as increased satiety. Moreover, recent data suggest that selective serotonin reuptake inhibitor (SSRI)-type medication improves outcome and prevents relapse in people with anorexia nervosa. These theoretical issues have important clinical implications in this era of diminished support for treatment of eating disorders. Anorexia nervosa, like other major psychiatric disorders, has contributory pathophysiology and can benefit from and deserves appropriate treatment resources.

Comparison of obsessions and compulsions in patients with anorexia nervosa and obsessive compulsive disorder.

Patients with anorexia nervosa (n = 18) and patients with obsessive-compulsive disorder (OCD) (n = 16) had similar scores on the Yale-Brown Obsessive Compulsive Scale (19 + or - 9 vs. 22 + or - 6). This suggests that these disorders have similar magnitude of impairment from obsessions and compulsions; however, OCD patients endorsed a wide variety of obsessions and compulsions, whereas anorexics tended to endorse symptoms that were related to symmetry and order.

Neuropeptide abnormalities in anorexia nervosa.

Starvation-induced alterations of neuropeptide activity probably contribute to neuroendocrine dysfunctions in anorexia nervosa. For example, CRH alterations contribute to hypercortisolemia and NPY alterations may contribute to amenorrhea. Alterations of these peptides as well as opioids, vasopressin, and oxytocin activity could contribute to other characteristic psychophysiological disturbances, such as reduced feeding, in acutely ill anorexics. Such neuropeptide disturbances could contribute to the vicious cycle that has been hypothesized to occur in anorexia nervosa. That is, the consequences of malnutrition perpetuate pathological behavior.

Treating eating-disorder patients in a managed care environment. Contemporary American issues and Canadian response.

This article addresses the effect of managed care on the treatment of eating disorders. We review strategies for negotiating limitations that managed care reviewers place on treatment. Finally, this article reviews the experiences of a Canadian program that has 10 years of experience in providing low-cost day treatment. While change is frustrating and difficult, it is inevitable and can be rejuvenating. These changes offer opportunities for creative development of quality low-cost care. If we do not adjust to these conditions, patients will not get treatment that they need.

Bulimia nervosa and substance dependence: association and family transmission.

Alcohol and drug use disorders are common among women with bulimia nervosa (BN) and their family members. However, it is not known whether there is a familial relationship between BN and substance use disorders. We compared 47 women with BN and 44 non-eating-disordered community control women, and their first-degree relatives (177 and 190, respectively). BN probands were stratified by the presence (43%) or absence (57%) of lifetime alcohol and/or drug dependence. The first-degree relatives of substance-dependent BN probands had significantly higher lifetime rates of alcohol/drug dependence (38%), compared with relatives of nonsubstance-dependent BN probands (10%) or relatives of community controls (18%). These data suggest that BN and substance dependence are transmitted independently in families.
