A 2-year, open-label followup was performed on 130 obsessive-compulsive patients who were responders to a previous 6-month treatment with clomipramine (150 mg/day), fluoxetine (40 mg/day), or fluvoxamine (300 mg/day). Continuation treatment with the same daily dose was compared to continuation with half doses or to discontinuation of pharmacotherapy. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Clinical Global Impressions (CGI) scale were used every 3 months, or whenever a worsening of symptoms was experienced. Maintenance treatments were found significantly superior to discontinuation in preventing relapses, and no differences in efficacy were found between full and half doses. A comparison of the three subgroups of patients who were withdrawn from drug therapy failed to demonstrate any statistical difference.

BACKGROUND: Growing evidence documents the frequent co-morbidity between Obsessive Compulsive Disorder (OCD) and Bipolar Disorder (BP) in adults. The aim of the present study is to explore some clinical aspects of this interface in children and adolescents, as it appears in a setting of routine clinical practice. METHOD: The sample comprised 102 consecutively referred children and adolescents, both inpatients and outpatients, with BP, OCD or co-morbid BP-OCD during a 3-year period. The mean age was 14.2 (SD=3.2); 65 (63.7%) were males. Diagnoses and clinical features were collected by means of structured interview according to DSM-IV (DICA-R) and a rating scale for OCD (CY-BOCS). Clinical outcome was evaluated prospectively by means of clinical global impression (CGI) as part of routine clinical care, throughout the follow-up. RESULTS: Thirty-seven (36.3%) patients (21 males and 16 females) were diagnosed as BP, 35 (34.3%) patients (26 males and 9 females) were diagnosed as OCD and 30 (29.4%) patients (18 males and 12 females) were diagnosed as BP-OCD. BP II, was more frequent in the BP-OCD than in BP. When OCD was co-morbid with BP, age of onset was significantly earlier than in the 'pure' OCD patients. On the contrary, age of onset of BP was not affected by co-morbid OCD. According to CGI baseline scores, OCD patients were significantly less impaired than BP-OCD and BP patients, while the severity of the symptomatology was similar in the last two groups. Severity scores at the end of the follow-up were significantly higher in BP-OCD patients than in OCD patients. Patients with pure BP showed lower rates of panic disorder-agoraphobia than BP-OCD patients and higher rates of ADHD-conduct disorder. Pure OCD patients showed lower rates of ADHD and higher rates of Generalized Anxiety Disorder. The number of obsessions did not differentiate the two groups, whereas pure OCD patients showed significantly more compulsions. 'Other' obsessions-e.g., existential, philosophical, odd and/or superstitious-were significantly more frequent in BP-OCD than in pure OCD patients. Ordering compulsions were significantly more frequent in pure OCD patients. LIMITATIONS: Possible low reliability of children's and their parents' recall of past episodes of mental disorder. CONCLUSIONS: In a tertiary care center, co-morbidity between OCD and BP is a significant clinical problem affecting a large number of patients. The correct identification of OCD-bipolar co-morbidity has relevant clinical implications as far as other concomitant disorders, symptomatological features, course, complications, and treatment management and outcome are concerned.
OBJECTIVE: The authors assessed the prevalence of compulsive buying (CB) among patients presenting an obsessive-compulsive disorder (OCD). They compared the buying style of patients with and without CB. METHOD: One thousand five hundred consecutive patients were assessed by a general practitioner in Paris (France). Sixty patients presenting with OCD were included. Patients with CB associated with OCD (n = 14) were compared with those with "pure" OCD (n = 46). Sixty patients paired for sex and age and free from OCD, depression, and anxiety were also recruited among the clients of the same general practitioner. We compared 3 groups: controls, patients with OCD, and patients with OCD + CB. RESULTS: Prevalence of CB was 23% (14 cases) among patients with OCD and 6% (4 cases) in controls (chi(2)(1) = 5.3, P = .02). Patients presenting with OCD + CB had a higher number of Diagnostic and Statistical Manual of Mental Disorders, Revised Fourth Edition diagnostic criteria for OCD than patients with pure OCD (6.1 and 5.4, respectively, P = .001). Depression was more frequent in the OCD + CB group (78%) than in the OCD group (42%) and in controls (10%) (P = .02). Patients from the OCD + CB group had higher score at the CAGE questionnaire than those of the OCD group (2 vs 0.7, P = .003). Patients with OCD + CB considered 42% of their purchases as occasions not to be passed up compared with 15.4% in the OCD group and 8.6% in controls. OCD+CD patients used the items they bought after a longer delay than controls and patients with pure OCD (8.2 vs 3 and 3.1 days, respectively). CONCLUSION: Compulsive buying is more frequent in OCD than in controls. Patients presenting with OCD + CB show more depressive disorders and drink more alcohol. They are more highly implicated in the items they buy and they are more often disappointed by the items once they possess them.
OBJECTIVE: Studies of the familiality of obsessive-compulsive disorder (OCD) have yielded inconsistent results. This study compared the familial aggregation of OCD in first-degree relatives of community subjects with never-treated OCD, outpatients with OCD, and comparison subjects. METHOD: Fifteen persons from the community with untreated OCD were matched on age and interview type (direct or through family informants) with 90 OCD patients from four treatment facilities and 70 comparison subjects. Direct or indirect interviews using the German-language version of the Schedule for Affective Disorders and Schizophrenia-Lifetime Version for Anxiety Disorders (DSM-IV) were obtained from 58, 285, and 247 first-degree relatives, respectively, of the three groups. The rate of OCD in case versus comparison relatives was assessed with chi-square tests, and odds ratios were calculated for risk estimation. Cox proportional hazards analysis was used to estimate the age-related risk of relatives of being affected by OCD. RESULTS: Cox proportional hazards analyses revealed a 6.2-fold higher risk (hazard ratio) for relatives of all OCD cases for definite OCD and a 2.2-fold higher risk for subclinical OCD compared with relatives of comparison subjects. For relatives of community subjects with OCD, the risk for definite OCD (10.3% versus 5.6%) was 1.6, and the risk for subclinical OCD (15.4% versus 4.1%) was 3.4 compared with relatives of OCD patients from treatment sites. CONCLUSIONS: These results from the first controlled European family study of OCD confirm earlier U.S. data on the familiality of OCD in patients recruited from treatment facilities. The finding of a comparable familial aggregation of definite OCD and a higher familial aggregation of subclinical OCD in relatives of never-treated persons with OCD from the community strongly supports the impact of familial-genetic factors in OCD.
Family studies suggest an interrelationship between Gilles de la Tourette Syndrome (GTS) and some forms of obsessive-compulsive disorder (OCD). Some authors consider GTS to be part of a serotonergically mediated cluster of OCD spectrum disorders. The present study was undertaken to compare measures of psychopathology, personality and blood serotonin between GTS and OCD (without tics), and to investigate whether an OCD spectrum hypothesis is supported for GTS. Fifteen GTS without OCD subjects, 21 tic with (+) OCD subjects, 15 OCD without tic subjects and 26 controls (all without serotonergic medication) were evaluated with self-rated and clinician-rated measures of psychopathology and personality. Whole blood serotonin (5-HT) and platelet monoamine oxidase activity (MAO) was measured, and Spearman's correlations were calculated between whole blood 5-HT, MAO and rating scale scores within the entire sample and within subgroups. There were main effects of OCD on anxiety, obsessive-compulsive, neuroticism and extraversion scores. There were main effects of tics on depression, obsessive-compulsive, trait anxiety and neuroticism scores, and on platelet MAO. There were interaction effects on platelet MAO, 5-HT, Yale-Brown Obsessive-Compulsive Rating Scale severity, trait anxiety and Eysenck Personality Questionnaire neuroticism scores. Platelet MAO activity was elevated in tic-free OCD subjects when compared to tic + OCD, GTS without OCD and controls. Whole blood 5-HT was lowered in tic + OCD patients in comparison to GTS without OCD and tic-free OCD subjects. Whole blood 5-HT and obsessive-compulsive severity were negatively correlated within OCD without tic patients and MAO and Leyton Obsessive Inventory scores were negatively related within GTS without OCD patients. The biochemical data of this study suggest that in tic + OCD and in tic-free OCD patients, 5-HT dysregulations play a role, but not necessarily in pure GTS. Serotonergic dysregulations within tic + OCD and tic-free OCD patients are distinct, suggesting differences in underlying pathophysiology. The finding that obsessions and compulsions can be associated with either 5-HT hypofunctionality or hyperfunctionality reveals a major weakness in the OCD spectrum theory, i.e. that the associations between obsessive-compulsive behaviours and 5-HT abnormalities are less specific than suggested by the original obsessive-compulsive spectrum model.
UNLABELLED: A significant proportion of patients suffering from Eating Disorders (ED) present a comorbidity with anxiety disorders. Among the anxiety disorders, Obsessive Compulsive Disorders (OCD) are the third most frequently diagnosis observed in ED. However, prevalence rates from the literature are contradictory depending on the diagnostic criteria and evaluation tools used. Studies concerning the chronology of appearance of OCD and ED and the role played by denutrition are even rarer and equally contradictory. OBJECTIVE: The aim of this study is to bring new empirical data to the study of the correlations between OCD and ED by exploring, in a significant clinical sample, the current and lifetime OCD comorbidity in the diagnostic sub-groups and sub-types of ED as defined by the DSM IV and to study the chronology of appearance of these disorders taking into account the role played by denutrition. We make the assumption that there should be a difference in the prevalence of obsessive compulsive disorders in the various ED sub-groups and sub-types and that purging anorexics should, at equivalent levels of denutrition, exhibit higher OCD prevalence rates than the other sub-types as a result of their more severe general psychopathology. METHODS: Current and lifetime prevalence were investigated using the Mini International Neuropsychiatric Interview (MINI) and the Yale-Brown Obsessive Compulsive Scale in a sample of 89 DSM IV eating disorders in and out-patients aged between 15 and 30 (58 AN and 31 BN) and 89 matched controls. In order to increase the validity of the current diagnosis of OCD only patients presenting an OCD diagnosis on the MINI (excluding obsessions and compulsions related to food and body image) and a score of 16 or more on the Y-BOCS were included in the study. RESULTS: Current and lifetime prevalence of OCD in ED is significantly higher than in general population (15.7% and 19% vs 0% and 1.1%, p < 0.05). Anorexic and bulimic patients do not show any difference in the current and lifetime comorbidity (19% and 22.4% vs 9.7% and 12.9%, ns). Concerning the diagnostic sub-types, following our assumption purging anorexics present the higher current and lifetime prevalences (29% and 43%), followed by restrictive anorexia (16%) and purging bulimia (13%). The only significant difference is found in the lifetime prevalence of OCD between purging and non purging anorexics. In the great majority of cases (65%) OCD diagnosis precedes ED diagnosis and OCD current prevalence and Y-BOCS scores of underweight patients are not significantly higher than normal weight patients, suggesting that there are only limited links between denutrition and obsessionality. LIMITS: Some methodological limitations must be considered. First of all, the small sample size of the diagnostic sub-types of ED do not enable us to draw definitive conclusions concerning the prevalence of OCD in the clinical forms of ED. Some of the diagnostic sub-types of ED, as BN-NP, appear at different ages: in order to better investigate the prevalence of OCD in all the diagnostic sub-types, larger age ranges should be considered. Secondly, our sample of anorexics is almost made of hospitalized inpatients recrutated in a specialized university unit, whereas bulimics are all consulting outpatients. It is possible that the higher than normal rates of OCD in anorexics could be related to the severity of this sample. Comparisons with samples of consulting anorexics should be performed. Lastly, it is necessary to evoke the limitation represented by the choice of a healthy control group. OCD are rare in the general population and the differences found between the clinical and the control groups do not offer strong arguments to support the specificity of the association between OCD and ED, which would be better explored by using a pathological control group. CONCLUSIONS: So far, none of the various models proposed to explain the comorbidity observed between ED and OCD appears completely satisfactory. ED and OCD would share a genetic vulnerability to a dysregulation of serotoninergic functioning which would predispose these subjects, depending on specific clinical and biological conditions, to develop an obsessional and compulsive symptomatology more or less focused on food and body image. The knowledge of the clinical and biological specificities of the ED diagnostic sub-types presenting an OCD comorbidity could point the way towards specific therapeutic interventions in these patients. Our study of the comorbidity of OCD in ED makes a further contribution to the identification of specific links between the OCD and the various clinical forms of ED. More clinical and biological studies are needed to further explore these relationships.
Stereotyped repetitive behaviors occur in Gilles de la Tourette's Syndrome (GTS) and obsessive-compulsive disorder (OCD). The present study was undertaken to compare the distribution of obsessive-compulsive and Tourette-related impulsive behaviors in GTS with (+) OCD, GTS without (-) OCD, tic-free OCD, and control subjects. Fourteen GTS + OCD, 18 GTS-OCD, 21 OCD-tic, and 29 control subjects were evaluated using a semistructured interview designed to assess GTS and OCD-related repetitive behaviors. Each reported item was evaluated on the presence of anxiety and goal-directedness. This information was subsequently used to define whether the repetitive behavior was an (anxiety-related) obsession or compulsion, or a (non-anxiety-related) OC-like behavior, impulsion. GTS + OCD subjects reported more overall Tourette-related impulsions than OCD-tic subjects, i.e., more mental play, echophenomena, and touching behaviors but similar frequencies of typical obsessive-compulsive behaviors. Further, GTS + OCD subjects exhibited more overall repetitive behaviors than GTS-OCD subjects, i.e., more Tourette-related impulsions as well as more obsessive-compulsive behaviors. The distribution of symptoms is similar in GTS with and without OCD, and differs from tic-free OCD. These differences suggest that GTS with OCD constitutes a form of GTS, not of OCD, although the possibility that GTS + OCD patients constitute a subgroup distinct from GTS and from OCD can not be excluded by this phenomenological study. Specific non-anxiety-related impulsions seem to discriminate between GTS and OCD-tic individuals. These impulsions possibly reflect differences in underlying mechanisms between GTS and OCD-tics.
Body dysmorphic disorder (BDD) is currently classified as a somatoform disorder in DSM-IV, but has been long noted to have some important similarities with obsessive-compulsive disorder (OCD). In addition, BDD and OCD have been often reported to be comorbid with each other. In the present study, we compared demographic characteristics, clinical features and psychiatric comorbidity in patients with OCD, BDD or comorbid BDD-OCD (34 subjects with BDD, 79 with OCD and 24 with BDD-OCD). We also compared the pattern of body dysmorphic concerns and associated behaviors in BDD patients with or without OCD comorbidity. In our sample, BDD and OCD groups showed similar sex ratio. Both groups with BDD and BDD-OCD were significantly younger, and experienced the onset of their disorder at a significantly younger age than subjects with OCD. The two BDD groups were also less likely to be married, and more likely to be unemployed and to have achieved lower level degree, than OCD subjects even when controlling for age. The three groups were significantly different in the presence of comorbid bulimia, alcohol-related and substance-use disorders, BDD-OCD patients showing the highest rate and OCD the lowest. BDD-OCD reported more comorbid bipolar II disorder and social phobia than in the other two groups, while generalized anxiety disorder was observed more frequently in OCD patients. Patients with BDD and BDD-OCD were similar as regards the presence of repetitive BDD-related behaviors, such as mirror-checking or camouflaging. Both groups also did show a similar pattern of distribution as regards the localization of the supposed physical defects in specific areas of the body. The only significant difference concerned the localization in the face, that was more frequent in the BDD group. Our results do not contradict the proposed possible conceptualization of BDD as an OCD spectrum disorder. However, BDD does not appear to be a simple clinical variant of OCD and it seems to be also related to social phobia, mood, eating and impulse control disorders. The co-presence of BDD and OCD features appears to possibly individuate a particularly severe form of the syndrome, with a greater load of psychopathology and functional impairment and a more frequent occurrence of other comorbid mental disorders.
