Urinary 3-methoxy-4-hydroxyphenethylene glycol (MHPG) excretion, which is thought to reflect CNS norepinephrine metabolism, has been shown to be significantly decreased in some depressed patients. Although there is consensus that urinary MHPG excretion varies directly with mood in rapidly cycling bipolar patients, there is little information on longer term state changes, such as those that accompany recovery from depression. Ten female patients with diagnoses of primary affective disorder were studied initially during an inpatient hospitalization and restudied at least ten months after discharge. Five healthy female comparison subjects were also studied over a similar interval of time. During the baseline period, the patient sample excreted less MHPG than did the comparison group. Improvement in clinical state from a seriously depressed baseline was associated with a significant increase in MHPG excretion, while the patients with recurrences of depression showed no change and continued to excrete less MHPG than the comparison subjects. These results suggest that urinary MHPG excretion may represent an index of psychobiological state in depressive patients.

The rigorous neo-Kraepelinean research criteria of the St. Louis/Iowa and Taylor groups were applied to case record data of 116 first admissions of Schneider-negative schizophrenics--that is, those without first-rank symptoms (FRSs)--hospitalized in a strongly Schneider-oriented German University Psychiatric Clinic from 1962 to 1971. This sample had a total of 45.7% (53 cases) of psychiatric illness diagnosable by research methods. Indeed, only 31% (36 cases) of Schneider-negative schizophrenics turned out to have research-positive Kraepelin-oriented schizophrenia; and of these, 21 fulfilled both sets of research criteria for schizophrenia. It is important that 14.6% (17 cases) of Schneider-negative schizophrenia consisted of research-diagnosable affective disorder, with mania making up 5.2% and depression 9.4% of this figure. The findings suggest that a sample of Schneider-oriented schizophrenia without FRSs as routinely diagnosed in Germany does not seem to represent a clear-cut homogeneous and 'uncontaminated' group of schizophrenics.

In a pilot study of 150 manic or depressive patients, the authors used the Research Diagnostic Criteria (RDC) and the Schedule for Affective Disorders and schizophrenia (SADS) to perform preliminary analysis of symptom pictures of the index episode of different diagnostic groups, joint diagnostic classification of the different subtypes of major depressive disorder, and differential outcome by diagnostic groups. The results suggest that schizophrenic symptoms in affective disorders do have diagnostic and prognostic significance, that the term "psychotic depression" should be limited to impaired reality testing without reference to degree of incapacitation, that situational-nonsituational and endogenous-nonendogenous classifications are separate depressive subtypes, and that it may not be true that patients with endogenous major depressive disorder have a better prognosis than patients with nonendogenous depression.

The authors evaluate the clinical and research significance of the diagnosis of secondary depression by comparing 48 cases of primary and 26 cases of secondary depression. The patients with secondary depression have a higher familial prevalence of alcoholism, affective disorder, and drug abuse. The groups differ somewhat on a few sociodemographic, behavioral, and attitudinal variables but are similar in symptomatology, sex ratio, onset and duration of symptoms, treatment received, and response to treatment. These results suggest that the distinction between primary and secondary depression should be retained in research that examines neurochemistry or genetics. Primary and secondary depression appear to be identical from the persepctive of clinical care. Management of these patients should emphasize the diagnosis of depression rather than antecedent diagnoses.

The hypothesis that pathologic immune mechanisms, characterized by production of brain autoantibodies, operate in schizophrenia, was the basis for this study. Binding of serum globulin substance by human brain septal region obtained at autopsy was measured by radioimmunofixation assay in 27 schizophrenic probands, 28 first-degree relatives, 12 patients with primary affective disorder (depression), and 117 normal controls. Schizophrenic individuals tended to have higher levels of brain-serum affinity than controls. Age and sex did not appear to affect results. Within families, elevation of serum-binding activity showed intra sib-pair resemblance, distinguished healthy relatives from probands and ill relatives and relatives of probands with positive sera from relatives of probands with negative serum activity. Serum activity distinguished well relatives from normal controls and was independent of clinical state. This suggests that brain-serum affinity may be compatible with characteristics of a genetic marker of vulnerability to schizophrenia. Within sib-pairs, concordance rates for elevated serum activity and for subtype diagnosis, mode, and age of illness onset were positively related. This finding supports clinico-genetic disposition in a subgroup of schizophrenic persons. To determine distribution patterns of antigenic components, selected schizophrenic and normal sera were tested against human liver and mouse brain, thymus, and liver. Wide tissue cross-reactivity was observed in schizophrenic, but not in normal sera, a finding consistent with overlap of serological reactions affecting specific tissues in autoimmune processes. The assay employed in the present study and investigation of inheritance of brain-serum affinity have not previously been reported.

The relationship between premenstrual affective syndrome and psychiatric disorder was investigated, using 81 women presenting to a Neurology Clinic with functional headache. Premenstrual affective syndrome was significantly associated with a history of depressive syndrome in the population studied. Patients judged to have a non-affective psychiatric disorder reported no greater frequency of definite or probable premenstrual affective syndrome than patients considered psychiatrically normal. The premenstrual occurrence or exacerbation of affective symptoms has been noted. This symptom exacerbation maybe sufficient to require hospitalization. Data presented by Coppen indicate that women with affective disorder are more likely to report the premenstrual symptom of depression than women with other psychiatric disorders. These findings suggest that there may be some relationship between depressive disorder and premenstrual affective symptoms. As part of a larger study on the personality and psychiatric correlates of functional headache, data on the relationship between depressive syndrome and premenstrual affective symptoms were obtained.

Eighty-five cases of atypical schizophrenia were compared with 200 of schizophrenia, 100 of bipolar (mania), and 225 of unipolar (depression) affective disorder. Comparisons were made on the basis of sex, age at admission, precipitating factors, outcome, and a family history of schizophrenia or of affective disorder. The atypical schizophrenia differed remarkably from the schizophrenia and most closely resembled the bipolar affective disorder when allowance was made for a younger age at onset and a higher frequency of precipitants. An analysis of symptoms verified the predominance of schizophrenic features in the atypical schizophrenia, but also showed a high percentage (80%) of patients who had one or more manic symptoms at index admission. It is concluded that great care should be taken in diagnosing schizophrenia in a patient who also has manic symptoms.

We have now postulated that differences in the innate capacity of individuals to synthesize, store and utilize biogenic amines may provide the biological basis for human abuse of narcotic and other drugs, and that these drugs are used in an apparent unconscious effort to self-medicate against an inherent affective disorder. In this communication, we attempted a preliminary characterization of the narcotics withdrawal syndrome on biochemical and clinical parameters. Abstinence was found to be characterized by low urinary excretion of 2-phenylethylamine and depression. An indication for use of tricyclic drugs has been discussed.

(1) Height, weight, total body potassium, exchangeable sodium, bromide space, total body water and concentrations of sodium, potassium and chloride in plasma were measured in control subjects and individuals suffering from alcoholism, with techniques which included body counting and a multiple isotope method using 24Na, 82Br and 3H2O. (2) No differences were found between control and alcoholic subjects so there was no evidence that chronic alcoholism altered body composition. In particular there was no eficence of cellular damage or loss which would have been reflected in changes in KT or KIN. (3) The data were combined and were analysed to give information on the relationships of the variates. (4) On-going work by the author on tryptophan metabolism in primary alcoholics is compared to Shaw's findings on the kinetic behaviour of tryptophan in affective disorder. The possible prophylactic value of L-tryptophan (Optimax) in preventing both recurrent depression and recurrent alcohol abuse is outlined. (5) Data on body composition in normal subjects not hitherto available in the literature is provided.

A systematic interview regarding family history was administered to 48 men with bipolar affective illness who were attending a lithium clinic. Several families were found in which both the patient and father had affective disorders, but the mother and maternal second-degree relatives were well. Of 30 men who had histories of hospitalization for mania, three had fathers with affective disorder (all bipolar). Of 18 men who had depression and hypomania, one father had unipolar depressive disorder. The hypothesis that bipolar manic-depressive illness may be transmitted by a single dominant genetic factor on the X chromosome is discussed in relation to these ill father-ill son pairs.
