[Catatonia education in France: A cross-sectional study]. / L'enseignement du syndrome catatonique en France : enquête nationale et état des lieux.

OBJECTIVES: Catatonia is a transnosographic syndrome described by K. Kahlbaum in 1874. Catatonia can be life-threatening due to its complications and in case of malignant catatonia. Safe and effective treatments have been identified (benzodiazepines and electro-convulsive-therapy). The prevalence of this syndrome is important and represents about 10% of inpatients in an acute psychiatric ward. However, this syndrome appears to remain under-diagnosed and poorly known. We were, therefore, interested in the current knowledge of French psychiatry residents and young psychiatrists as well as the education they had received about catatonia. METHODS: A questionnaire was submitted to French psychiatry residents and young psychiatrists with fewer than 5 years of experience. It included questions about knowledge of the symptoms, complications, causes and treatments of catatonia. Participants were also asked about their confidence in the management of a patient with catatonia and about the number of catatonic patients they had already met. The type of lecture and teaching about catatonia was also assessed. RESULTS: Among the 376 psychiatrists that completed the questionnaire, 37.5% never had received any specific teaching about catatonia. Concerning the 62.5% who benefited from a specific lecture, this was mainly delivered as part of psychiatry DES. Heterogeneity in the education delivery on the French territory had been highlighted. In addition, participants' knowledge of catatonic syndrome seems incomplete. However, knowledge of catatonic symptoms and first intention treatments was significantly better among respondents who were part of the "with education" group. The confidence in catatonia recognition and management, as well as the number of catatonic patients they met, are also significantly higher in the group "with education". CONCLUSION: Specific education seems to improve the knowledge of young doctors and their ability to diagnose and treat catatonic patients. This education remains poorly provided and heterogeneous on the French territory. Catatonia deserves a place in the teaching program of the psychiatry DES, thus to become systematic.

Mast cells' involvement in inflammation pathways linked to depression: evidence in mastocytosis.

Converging sources of evidence point to a role for inflammation in the development of depression, fatigue and cognitive dysfunction. More precisely, the tryptophan (TRP) catabolism is thought to play a major role in inflammation-induced depression. Mastocytosis is a rare disease in which chronic symptoms, including depression, are related to mast cell accumulation and activation. Our objectives were to study the correlations between neuropsychiatric features and the TRP catabolism pathway in mastocytosis in order to demonstrate mast cells' potential involvement in inflammation-induced depression. Fifty-four patients with mastocytosis and a mean age of 50.1 years were enrolled in the study and compared healthy age-matched controls. Depression and stress were evaluated with the Beck Depression Inventory revised and the Perceived Stress Scale. All patients had measurements of TRP, serotonin (5-HT), kynurenine (KYN), indoleamine 2,3-dioxygenase 1 (IDO1) activity (ratio KYN/TRP), kynurenic acid (KA) and quinolinic acid (QA). Patients displayed significantly lower levels of TRP and 5-HT without hypoalbuminemia or malabsorption, higher IDO1 activity, and higher levels of KA and QA, with an imbalance towards the latter. High perceived stress and high depression scores were associated with low TRP and high IDO1 activity. In conclusion, TRP metabolism is altered in mastocytosis and correlates with perceived stress and depression, demonstrating mast cells' involvement in inflammation pathways linked to depression.

[Evolution in styles of romantic and interpersonal attachment in depressed adult women during hospitalization]. / Évolution des styles d'attachement romantique et interpersonnel au cours de l'hospitalisation chez des femmes adultes déprimées.

INTRODUCTION/OBJECTIVE: Bowlby (1984) regarded attachment as a model of psychological vulnerability to depression. Since then, a large number of studies have considered vulnerability to depression in light of the idea of attachment style. Attachment styles correspond to two dimensions observed in relationships (anxiety and avoidance) evoking ideally the internal operating models of self and other respectively, as first described by Bowlby (1984). Two types of adult attachment styles are evaluated in our study: romantic attachment (Hazan and Shaver, 1987) and interpersonal attachment (Bartholomew and Horowitz, 1991). The existing literature indicates that depression is associated with the insecure attachment styles, in both romantic an interpersonal relationships. Nevertheless, a question remains concerning the nature of the link between attachment style and depression: are attachment styles stable and independent of the depression or are they modified as the depression evolves? The aim of the present study was to investigate the relationships between attachment and depression in adult women hospitalized for depression; following up the evolution in their romantic and interpersonal attachment styles from the beginning to the end of their hospitalization. METHODOLOGY: The study population consisted of 50 women hospitalized for an episode of major depression (Axis I, DSM IV). Individuals exhibiting bipolar disorders and other pathologies linked to depression were not included in the population. Sixty-eight percent of the depressed women in our population had previously experienced depressive episodes and 42% of them also exhibited a personality disorder (Axis II, DSM IV). The clinical group participated in two psychological investigations, one at the beginning (T1) and one at the end of the hospitalization (T2), including each time a clinical interview during which the depression as well as the romantic (ECR, 1998) and interpersonal (RQ, 1991) attachment styles were evaluated. STUDY RESULTS: Our findings showed that depression is positively correlated with the "avoidant" dimension of the romantic attachment style and negatively with the "secure" dimension of the interpersonal attachment style. Between the beginning and the end of hospitalization, only the "secure" and "fearful" dimensions of the interpersonal attachment styles were modified, whereas the styles of romantic attachment remained stable. In terms of the links between attachment styles and the evolution of depression during hospitalization (between T1 and T2), we noted that an increase in security of attachment was correlated with a decrease in the depressive symptomatology. Conversely, the other romantic and interpersonal attachment styles were not linked with the evolution of the depressive symptomatology. DISCUSSION/CONCLUSION: Our results confirm that romantic and interpersonal styles of attachment constitute factors of vulnerability to depression. But more importantly, these findings open up new perspectives in terms of the nature of the relationships between attachment styles and depression. They provide matter for discussion concerning the stability or the change in romantic and interpersonal attachment styles. Indeed, we have revealed the stable and independent nature of romantic attachment styles in relation to depressive symptomatology. On the contrary, security in the interpersonal attachment style was shown to be a factor of change, associated with the evolution of the depressive symptomatology in progress. In the quest to take combined account of romantic and interpersonal attachment styles and their links with the evolution of depression, the present study results in a new understanding of depression, viewed from the perspective of the model of attachment in adults.

Autoantibodies of various specificities encoded by genes from the VH J558 family bind to foreign antigens and share idiotopes of antibodies specific for self and foreign antigens.

We examined the binding to foreign antigens and the expression of crossreactive idiotypes by a panel of 20 murine monoclonal autoantibodies encoded by V genes from the VH J558 family. 9 of 20 antibodies bound to foreign antigens such as bacterial polysaccharides, poly(Glu50, Tyr50), poly(Glu54,Lys37,Phe9), arsonate, and lysozyme, known to interact with antibodies encoded by genes from the VH J558 family. A high proportion of our panel of autoantibodies expressed crossreactive idiotypes originally borne by monoclonal rheumatoid factors, anti-Sm, and anti-DNA antibodies, all encoded by V genes from the VH J558 family. Some of these VH J558+ autoantibodies shared crossreactive idiotypes with VH J558+ antibodies directed against foreign antigens such as influenza virus hemagglutinin, poly(Glu60,Ala30,Tyr10), arsonate, and dextran. The implications of these findings are discussed with respect to the process of activation of self-reactive clones.

[Subjective quality of life profile in patients with multiple sclerosis]. / Profil de qualité de vie subjective chez les sujets atteints de sclérose en plaques.

OBJECTIVES: This study aimed to assess subjective quality of life in patients with multiple sclerosis regarding the criteria of satisfaction and importance attached to various domains of life. METHOD: Sixty-one subjects took part in this study. The psychological evaluation consisted of a clinical interview and three questionnaires: subjective quality of life profile (PQVS), State-Trait anxiety inventory (STAI), Beck depression inventory (BDI). RESULTS: The results show a low level of general satisfaction of subjective quality of life. Fatigue and pain are the most unsatisfactory domains of life while the relationships with close relations and medical staff are perceived as the most satisfactory and important domains of life. Some differences are observed between men and women regarding the satisfaction of conjugal life and fatigue perception. The subjective quality of life seems mainly correlated to anxiety, depression and to the level of handicap. CONCLUSIONS: Our results emphasize the necessity of taking into account the subjective perception of the disease which can lead in an appropriated treatment. These results underline the place of anxious and depressive disorders associated with multiple sclerosis, which seem to have a certain impact on the subjective quality of life.

Type A competitiveness traits correlate with downregulation of c-Fos expression in patients with type 1 diabetes.

AIM: Type A personality has been associated with increased survival in people with type 1 diabetes (T1D). Systemic low-grade inflammation may play a critical role, as suggested in recent reports, although the links between the inflammatory circulating transcriptome and Type A remain unknown. This prompted our exploration of the potential associations between Type A personality and c-Fos gene expression, a candidate gene closely linked to inflammatory processes, in T1D. METHODS: Type A personality was assessed by Bortner questionnaire in patients with T1D, and two subscales - 'speed' and 'competitiveness' - were used to measure these specific dimensions of Type A. Expression of the c-Fos gene was assessed by a quantitative real-time polymerase chain reaction technique. RESULTS: This pilot study included 20 men with T1D. Multivariable analyses showed an independent inverse association between Type A competitiveness score and c-Fos expression, while a regression model adjusted for age, body mass index and HbA1c levels revealed a significant inverse relationship between c-Fos transcripts and Type A competitiveness (P = 0.003). CONCLUSION: This strong association between Type A competitiveness and reduced c-Fos expression is in line with recent data suggesting a psychobiological influence of the Type A profile in T1D via inflammatory pathways.

[Alexithymia and links with depression and anxiety in multiple sclerosis]. / Alexithymie et liens avec la dépression et l'anxiété dans la sclérose en plaques.

OBJECTIVES: This study evaluates the prevalence of alexithymia in multiple sclerosis and examines the links between alexithymia, depression and anxiety. METHOD: Sixty-one subjects aged between 18 and 60 years and suffering from multiple sclerosis took part in the study. The psychological assessment consisted of an interview with a psychologist and three questionnaires: the Toronto Alexithymia Scale (TAS), the State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory (BDI). RESULTS: The prevalence of alexithymia was 42.5%, 34.4% for depression and 44.3% for anxiety (high and moderate level). The alexithymic subjects were more depressed and anxious. Results indicated positive correlations between anxiety (state and trait), depression and alexithymia scores. The various dimensions of alexithymia were found to be diversely correlated with anxiety and depression. CONCLUSIONS: Our results point out the importance of anxiety in multiple sclerosis and the specificity of alexithymia.

[Styles of attachment and social support perceived in depressed women]. / Styles d'attachement et soutien social perçu chez des femmes déprimées.

RESULTS: This study, inspired by the attachment model and research in the field of social support, attempts to reveal the link between styles of attachment, social support and depressive vulnerability. AIM OF THE STUDY: It investigates current styles of attach-ment and the quality of social support perceived by 35 hospitalized, depressed subjects compared to 35 control subjects who exhibited no pathology. After giving their consent, each subject took part in an in-depth psychological investigation consisting of a recorded clinical interview and various clinical scales. METHOD: The study presents only the responses to the Perception of Relations questionnaire which distinguishes between four styles of attachment (secure, detached, preoccupied and disorganized) and the Social Support Questionnaire (SSQ6) which contains two dimensions: social availability and social satisfaction. The results were subjected to statistical analyses: a comparative analysis between the two groups and a correlational analysis between the dimensions of social support and the dimensions of style of attachment. On the one hand, the study reveals that the social network is perceived to be less available by depressed subjects, together with the absence of a current intimate relationship with other people, the absence of people to confide in, and a relationship between this absence and the large number of losses experienced by depressed subjects, in particular the loss of figures of attachment (father and mother). On the other hand, depressed subjects tend to exhibit a preoccupied, disorganized style of attachment which is characterized by negative models of the self. DISCUSSION: The discussion addresses the way these styles of attachment should be understood: do they represent the consequence of the depressive pathology or an older relational style?

Potential influence of Type A personality on plasma C-reactive protein levels in people with diabetes.

AIM: Type A personality, although classically known as a factor linked to increased vascular risk, has recently been associated with increased survival in patients with diabetes. As low-grade inflammation predicts a poor outcome, the present study explored the potential associations between Type A and plasma levels of C-reactive protein (CRP) in diabetes. METHODS: Type A personality was assessed by the Bortner questionnaire in people with diabetes. The association between Type A and plasma CRP levels was examined by multivariable linear regression, and structural equation modelling (SEM) was performed to determine the impact of the major clinical, biological and psychological confounders. RESULTS: The study included 626 participants with type 1 and type 2 diabetes from the Diabetes and Psychological Profile study. Multivariable analyses showed an independent inverse association between Type A score and CRP levels. The structural model adjusted for age, gender, diabetes type and duration, body mass index (BMI), smoking status, alcohol abuse, oral antidiabetic and statin treatments, HbA1c levels, lipids, perceived stress, anxiety and depression revealed significant associations between CRP and Type A (ß=-0.135, 95% CI: -0.242, -0.028; P=0.014), BMI (ß=0.194, 95% CI: 0.038, 0.350; P=0.015) and HDL cholesterol (ß=-0.132, 95% CI: -0.245, -0.020; P=0.014). CONCLUSION: Our present study data indicate that Type A personality is independently associated with lower CRP levels. This lower level of inflammation might explain the better clinical outcomes associated with Type A personality in patients with diabetes.

Glucose homeostasis during spontaneous labor in normal human pregnancy.

Using stable isotope, glucose turnover was measured in six normal pregnant women during the various stages of labor; during the latent (A1) and active (A2) phases of cervical dilatation, during fetal expulsion (B), and during placental expulsion (C). These data were compared to measurements made in five postpartum women. Pancreatic hormones and cortisol were also measured. In four other normal women undergoing spontaneous labor, catecholamines and free fatty acids were measured. Plasma glucose increased throughout labor from 4.0 +/- 0.2 (A1) to 5.5 +/- 0.5 mmol/L (C) (P < 0.01), compared to 4.7 +/- 0.1 in the postpartum women. Glucose utilization and production were increased throughout labor at 33.4 +/- 3.1 and 32.8 +/- 3.1 mumol/kg min, respectively, compared to 8.2 +/- 0.9 in postpartum women. Glucose metabolic clearance was also increased to 7.5 +/- 0.8 mL/kg.min compared to that in nonpregnant women (1.8 +/- 0.3). Plasma insulin remained at 59 +/- 5 pmol/L during stages A1, A2, and B, but increased to 115 +/- 15 pmol/L during stage C. Plasma glucagon was increased throughout labor at 127 +/- 7 pg/mL, compared to 90 +/- 4 pg/mL in control postpartum women. Plasma cortisol increased during labor from 921 +/- 136 to 2018 +/- 160 nmol/L, compared to 645 +/- 355 during the postpartum period. Epinephrine and norepinephrine also increased during labor from 218 +/- 132 pmol/L and 1.09 +/- 0.16 nmol/L to 1119 +/- 158 and 3.61 +/- 1.04, respectively. It is concluded that labor is associated with a marked increase in glucose utilization and production. These findings suggest that muscle contraction (uterus and skeletal) independent of insulin is a major regulator of glucose utilization during labor. Furthermore, the increase in hepatic glucose production could be favored by an increase in glucagon, catecholamines, and cortisol.

Tricyclic antidepressant-induced extrapyramidal side effects.

Two cases of tricyclic antidepressant-related extrapyramidal side effects are reported and, the authors review the literature describing these effects. Despite clear case reports, these side effects are not well known. Given the wide prescription of tricyclic antidepressants (TCA) and the low number of case reports, the prevalence of these side effects is indeed low, but clinical implications exist. The extrapyramidal symptoms induced by TCA alone are acute or tardive dyskinesia, akathisia, myoclonus, rabbit syndrome and dystonia. These symptoms seem to be non age-related, but often dose-related, and were responders to antiparkinsonian agents or propranolol. The factors that predispose an individual to the development of these side effects are not completely understood. Some risk factors such as prior exposure to neuroleptics and/or lithium or estrogens could facilitate the development of these side effects. In some cases, they can disappear even though the same dose of TCA is continued, and they do not seem to be a drug class reaction. The susceptibility of each individual patient to the development of these disorders may be limited to only one or a few of these agents.

CYP 2D6 PM phenotype hypothesis of antidepressant extrapyramidal side-effects.

Extrapyramidal symptoms occur as side-effects of neuroleptics. For many years, case reports of such side-effects, linked to antidepressant treatments, have been published, but this phenomenon is not well known. Tricyclic and serotonergic antidepressants are both involved. The authors present an hypothesis which provides one possible neurobiochemical explanation for the aetiology of these side-effects. The proposed explanation is related to the inhibition of the CYP 2D6 isoenzyme by antidepressants (or neuroleptics) that may be involved in the genesis of the observed extrapyramidal side-effects.

[Drug interactions and new antidepressive agents]. / Interactions médicamenteuses et nouveaux antidépresseurs.

The mechanism of action of new antidepressants is characterized by a specific inhibition of the serotonin reuptake at synaptic level. In France, fluoxetine, fluvoxamine, and more recently paroxetine are extensively used. Based on a review of the literature, the authors report the interactions of these new antidepressants with psychotropic and other drugs, that are frequently associated with them. All studies report the frequent occurrence of interaction when the new serotonergic antidepressants are associated with tricyclic ones. The increase of tricyclic drug plasma levels is often high with side effects as a consequence. If the pharmacodynamic aspects of these interactions are not well known, the pharmacokinetics are easier to understand, due to the power of these new antidepressants to inhibit cytochrome P450.

[Comparative study of two techniques for the determination of amitriptyline and nortriptyline: EMIT and gas chromatography]. / Etude comparative de deux techniques de dosage de l'amitriptyline et nortriptyline: EMIT et chromatographie gazeuse.

Amitriptyline and nortriptyline plasma level results obtained with gas chromatography and enzyme immunoassay were compared in 46 patients. The limits and problems with Emit measurement are discussed.

Drug extrapyramidal side-effects or not: is there a dextromethorphan phenotype difference?

A recent hypothesis suggests the possible role of cytochrome P450 2D6 (CYP2D6) polymorphism (involved in the metabolism of a large number of drugs), as a potential risk factor for the development of extrapyramidal side-effects of psychotropic drugs. The CYP2D6 metabolizer phenotype (dextromethorphan test) of 31 drug treated psychiatric adult patients suffering from extrapyramidal side-effects (group 1) and of 31 matched patients without drug side effects (group 2) were compared. In the first group, 13 poor metabolizer patients (41.9 per cent) were found, characterized by a dextromethorphan metabolic ratio > 0.3, and only two patients in the second group (6.4 per cent). These data provide some support for the notion that in subjects in whom CYP2D6 is probably saturated, the risk of drug extrapyramidal side-effects may be increased. In such patients the choice of psychotropic drugs 'without' this risk must be preferred.

[Undesirable effects of drugs. Epidemiologic study at a psychiatric service of a university hospital]. / Effets indesirables medicamenteux. Etude epidemiologique dans un service de psychiatrie hospitalo-universitaire.

The authors reviewed the drug side effects observed in their ward during the 5 last years (1988-92). These alleged effects occurred at a very low incidence, 3 per cent, (116 cases on 3809 hospitalizations). As mentioned in the literature, the occurrence was higher in females (60 per cent), than in males. The age seemed not to be a risk factor in that population, the mean age being 44 for the men and 45 for the women. All side effects disappeared after decreasing or stopping the suspected drug. In 6 cases the suspected drug was not a psychotropic agent. The authors presented some of the more often reported cases, and some of the more recently known, such as extrapyramidal side effects with antidepressants, increase of the libido with serotonergic antidepressants. The problem fo polytherapy is discussed. In half (59/116) of the cases there was a psychotropic association. The side effect may be due to a pharmacokinetic interaction in 16 cases, either with enzymatic inhibitors like dextropropoxyphene, valpromide, valproic acid, fluvoxamine and fluoxetine, or with enzymatic inducers like carbamazepine. The authors compared the side effects of the antidepressants mainly used in their ward (amitriptyline, clomipramine, fluvoxamine and fluoxetine).

[Prediction of suicide risk]. / Prédiction du risque suicidaire.

Suicide is a great problem for public health. In France it causes more than 12,000 deaths every year, and it has been estimated that 45 to 70% of these subjects were suffering of affective disorders. Some epidemiological aspects of the links between suicide and depression are analytic and concern the risk factors of suicide among depressed patients: sociodemographic factors: risks are more important for men and for people living alone or suffering of social and affective isolation. Violent suicides increase with age; clinical and evolutive characteristics of the illness: the risk of suicide is correlated with the global severity of the depression, whatever are the nosographic subtypes, with anxiety, sleep disorders and anhedonia, with personal and familial history of suicide; among biological factors, a decrease of 5-HT transmissions has been implicated, but it seems to be more correlated with a modification of the ability to delay, with a poor impulse control. The association of several of these factors increases suicidal risk but it is impossible to describe a specific picture of the depressed suicidal patient, and clinical scales to estimate suicide risk are of limited interest. Finally, the clinical vigilance adapted to each individual case and the quality of the therapeutical relation remain the most important point for preventing suicide.

[Dexamethasone test: suppressors and non-suppressors, what's the difference?]. / Test à la dexaméthasone: suppresseurs et non suppresseurs, quelle différence?

In sixty-six depressed in-patients, 20 of them showed marked resistance to suppression after dexamethasone. The authors found no difference between the two subgroups of suppressors and non suppressors, when considering the following parameters: age, sex, duration of illness, number of prior episodes, family history, intensity of depression, response to antidepressant treatment, relapses, diagnoses. Furthermore the normalization of DST after a 28 day treatment did not systematically correlate with a good clinical improvement.

[Abuse of tianeptine. A case report]. / Abus de tianeptine. A propos d'un cas.

The authors report a case of tianeptine abuse in a 30 year-old woman. After a medical prescription of the recommended dosage of 12.5 mg 3 times daily of oral tianeptine for a depressive illness, the patient spontaneously increased the dosage which after two months reached 150 tablets per day. No severe toxic effects were observed. As adverse effects, the patient, in the beginning of this high treatment period suffered from nausea, vomiting, abdominal pain, anorexia with weight loss, constipation. These side effects progressively disappeared. The biological tolerance was excellent, and hepatic parameters were not affected. The patient experienced and seek a psychostimulant effect. After seven months of such a therapy, she was hospitalized to undergo a withdrawal. The discontinuation of the tianeptine treatment occurs in four days. A withdrawal syndrome marked by myalgia, and cold feeling was transient, and alleviated by sedative phenothiazine (cyamemazine) and myorelaxant benzodiazepine (tetrazepam).
