Substance dependence and eating disorders: impact of sequence on comorbidity.

There is a high comorbidity between eating disorders and substance dependence. The sequence of illness may indicate differences in the underlying pathology and could reflect different etiologies and treatment. The present study subjects were 218 inpatients and outpatients with diagnoses of anorexia nervosa binge-purge type (AN-BP), bulimia nervosa (BN), and eating disorder NOS (ED-NOS). Of these 218 patients, 38 had substance dependence predating the eating disorder (SDED), 71 had an eating disorder predating the substance dependence (EDSD), and 109 had only an eating disorder (ED-only). All subjects were administered the Structured Clinical Interview for DSM-III-R, Patient Edition With Psychotic Screen (SCID-P). EDSD patients had an earlier onset of the eating disorder than SDED patients and had the greatest prevalence of comorbid pathology. SDED patients were dependent on more substances. We conclude that the sequence of development of the eating disorder and substance dependence in eating disorder patients influences the amount of comorbid psychopathology. Clinical implications and future research are discussed.

Differences in DSM-III-R and DSM-IV diagnoses in eating disorder patients.

Two hundred eighty-eight eating disorder patients were administered the DSM-III-R Structured Clinical Interview (SCID) and the DSM-IV SCID for axis I and II. Concordance between DSM-III-R and DSM-IV was excellent for the axis I affective and anxiety disorders, bulimia nervosa, and substance abuse/dependence. It was also excellent for axis II paranoid, schizoid, borderline, and antisocial personality disorders. Agreement between the two nosological systems was lower for alcohol abuse/dependence with a kappa of.63. Kappas were also poor for the following personality disorders: schizotypal (.44), histrionic (.29), dependent (.54), obsessive-compulsive (.62) and not otherwise specified (.63). There was a substantial difference in the diagnosis of anorexia nervosa between DSM-III-R and DSM-IV. Fourteen patients were diagnosed with anorexia nervosa, binge/purge type, using DSM-IV criteria, while only six received the diagnoses of anorexia nervosa and bulimia nervosa using DSM-III-R criteria. Kappa was.49 and the percent agreement was 79%. While there are considerable areas of overlap in DSM-IV and DSM-III-R, there are also areas of substantial differences. Clinicians and researchers must be very cautious when attempting to compare data from the different nosologies.

Plasma and erythrocyte amino acid concentrations in anorexia nervosa.

Plasma and erythrocyte amino acid concentrations in seven female patients in the acute stage of anorexia nervosa were compared with values in the same subjects after refeeding, and with normal controls. We also compared these values with literature values from patients with protein-calorie malnutrition and prolonged starvation in an attempt to identify a biological indicator of severity and prognosis. Our data indicate: (1) Routine laboratory analyses that reflect protein status do not differentiate normal subjects from patients with anorexia nervosa. (2) The plasma aminogram in the acute stage of anorexia nervosa differs from normal, and differs from values reported for both protein malnutrition and prolonged starvation. (3) The Whitehead ratio clearly separates the acutely ill anorectic state from the treated state and from normal controls. (4) Both erythrocyte and plasma amino acid concentrations differ from normal in anorexia nervosa, but changes in erythrocyte concentrations are more obvious. (5) Erythrocyte glycine concentrations are unique, in that values were persistently elevated at all stages of illness in anorexia nervosa. (6) Erythrocyte-to-plasma amino acid ratios do not provide a biological index of severity and prognosis for patients with anorexia nervosa, in contrast to data reported for individuals with protein malnutrition.
