The descriptive epidemiology of obsessive-compulsive disorder.

Since the early eighties, there has been a growing interest in the descriptive epidemiology of obsessive-compulsive disorder (OCD). In this narrative review, the authors describe the findings of a number of studies that employed selected instruments, such as the Diagnostic Interview Schedule, the Composite International Diagnostic Instrument, and the Schedule for Affective Disorders and Schizophrenia, to ascertain the prevalence and incidence rates for OCD in several different countries. We noted that there is a great heterogeneity of findings and that the potential reasons for this variability include not only the intrinsic characteristics of the population under study but also extrinsic factors (i.e., the several methodologically-informed decisions that are to be made before undertaking such investigations, such as the adoption of a specific diagnostic instrument). In order to further the knowledge on the epidemiology of OCD, it would be worthwhile to establish a global consensus regarding a standard assessment package for OCD, to produce more cross-culturally valid versions of the key research instruments, and to conduct studies specifically aimed at comparing the sociodemographic, clinical and prognostic aspects of OCD across different countries.

The problem of delusional ugliness: is it really body dysmorphic disorder?

Currently, the DSM-IV allows individuals with dysmorphic delusions to be diagnosed with either delusional body dysmorphic disorder (BDD) and delusional disorder, somatic type (DDST). However, given the growing acceptance of a dimensional perspective in psychopathology, it is conceivable that future editions of the DSM may recommend the exclusion of the diagnosis of DDST whenever isolated dysmorphic delusions are present, arguing that the latter should be considered no more than a symptom of BDD. But is the concept of DDST condemned to extinction in favor of that of delusional BDD? While some studies suggest that non-delusional and delusional BDD/DDST may be indistinguishable from the clinical, neuroanatomical, and therapeutic perspectives, several facts support the utility of the DDST concept. Firstly, DDST is a wider construct than delusional BDD. Secondly, it is unclear whether DDST in general (as opposed to delusional BDD) belongs to the obsessive-compulsive spectrum. Thirdly, differential pharmacological response may not be an adequate criteria for blending non-delusional and delusional BDD/DDST. Fourthly, "delusional" BDD may not be delusional at all. Finally, there is more about delusion than just an "extreme" conviction. Future studies are urgently needed in order to substantiate our judgement regarding the existence of diagnostic limits between delusional BDD and DDST with dysmorphic delusions.

Ziprasidone in bipolar disorder.

Ziprasidone is a second-generation antipsychotic currently marketed for the treatment of schizophrenia and bipolar mania. It has a unique receptor profile that includes high-affinity antagonist activity at 5-hydroxytryptamine (5-HT) 2A, D2, 1D and 2C receptors, a potent agonist activity at 5-HT1A receptors and a relatively high affinity for the 5-HT and noradrenaline transporters. The efficacy of ziprasidone in bipolar mania (current episode, manic or mixed) has been well demonstrated in three placebo-controlled trials. In a three-arm controlled study, ziprasidone was shown to be efficacious in dysphoric mania, whereas haloperidol was comparable to placebo. Open-label treatment for up to 52 weeks supported the sustained efficacy of ziprasidone in bipolar disorder. Combined with lithium, ziprasidone has been shown to be efficacious as an augmenting agent in the acute treatment of mania, with sustained efficacy up to 1 year. Ziprasidone was very well tolerated by patients with bipolar disorder and did not cause increased weight, glucose or lipid levels.

A sociodemographic, phenomenological, and long-term follow-up study of patients with body dysmorphic disorder in Brazil.

OBJECTIVE: The main characteristic of body dysmorphic disorder (BDD) is a preoccupation with an imagined defect in appearance in a normal-appearing person or an excessive preoccupation with appearance in a person with a small physical defect. In this non-controlled study, our objective was to describe the socio-demographic, phenomenological, and long-term outcome features of a Brazilian sample of patients with BDD. METHODS: We performed a chart-review of the 166 patients who attended the Obsessions, Compulsions, and Impulsions Subprogram of the Institute of Psychiatry of the Federal University of Rio de Janeiro, Brazil, during the period between 1998 and 2005. RESULTS: Twenty patients (12%) had clinically significant BDD. This sample was characterized by a predominance of female (n = 11; 55%), single or divorced (n = 18; 90%), and economically unproductive patients (n = 17; 85%). We found an average of 2.5 current imagined defects per patient. The most frequently reported body parts of excessive concern were the overall appearance, size or shape of the face (n = 7; 35%), the skin (n = 6; 30%), the hair (n = 6; 30%), the nose (n = 5; 25%), and the body build and weight (n = 5; 25%). Most individuals exhibited a chronic condition (n = 13; 65%) and kept the same concerns during the course of the disorder (n = 12; 60%). All patients displayed compulsive behaviors, including recurrent mirror checking (n = 14; 70%), camouflaging (n = 13; 65%), reassurance seeking by means of repetitive questioning of others (n = 9; 45%), and excessive use of cosmetics (n = 7; 35%). Two patients reported "do-it-yourself" surgeries. Seven patients had current suicidal ideation (35%). Six patients (30%) showed no insight over their dysmorphic beliefs. Fifteen patients (95%) exhibited psychiatric comorbidities, mostly obsessive-compulsive disorder (OCD) (n = 14, 70%) and major depressive disorder (n = 11; 55%). The majority of patients were treated naturalistically with serotonin reuptake inhibitors (n = 15; 75%), either solo or in association with antipsychotics (n = 10; 50%). Nevertheless, only 5 (25%) responded favorably to treatment during the long-term follow-up (CGI < or = 2). CONCLUSIONS: BDD is a severe disorder that is frequently associated with other psychiatric conditions and responds poorly to treatment in the naturalistic setting. No significant trans-cultural variations were identified in the comparison between Brazilian, North American, and European samples.

A three-year follow-up study of patients with the respiratory subtype of panic disorder after treatment with clonazepam.

The demographic, clinical and therapeutic features of the respiratory subtype of panic disorder (PD) versus the non-respiratory subtype were studied in a prospective design. Sixty-seven PD outpatients (DSM-IV), who had previously been categorized into respiratory (n=35) and non-respiratory (n=32) subgroups, were openly treated with clonazepam for a 3-year period. The principal measure of efficacy was the number of panic attacks, obtained from the Sheehan Panic and Anticipatory Anxiety Scale. In the first 8 weeks of treatment (acute phase), the respiratory subtype group had a significantly faster response to clonazepam. During the follow-up (weeks 12-156), the two subgroups did not differ significantly in the number of panic attacks experienced from baseline to end point. Patients in the respiratory subtype were characterized by a later onset of disorder and a family history of PD. Patients in the non-respiratory subgroup had a significantly higher number of past depressive episodes than those in the respiratory subgroup. The respiratory subgroup had a faster response after 8 weeks of treatment and an equivalent response in the 3-year follow-up period. Clonazepam had a sustained therapeutic effect over the entire treatment period.

Clinical subtypes of obsessive-compulsive disorder based on the presence of checking and washing compulsions.

OBJECTIVE: We aimed at examining the utility of checking and washing compulsions as markers of valid subtypes of obsessive-compulsive disorder (OCD). METHODS: One hundred and six patients with obsessive-compulsive disorder were evaluated with a socio-demographic and clinical questionnaire, the Structured Clinical Interview for DSM-IV, the Yale-Brown Obsessive-Compulsive Scale, the Clinical Global Impression, the Beck Depression Inventory, the Hamilton Rating Scale for Depression, and the Global Assessment of Functioning. These individuals were allocated in one of four subgroups [checkers (OCD-Ch; n = 20), washers (OCD-Wa; n = 13), checkers and washers (OCD-CW; n = 48), and non-checkers and non-washers (OCD non-CW = 25)] on the basis of the presence and the clinical relevance of checking and/or washing compulsive behaviors across their lifetime. Socio-demographic and clinical variables were compared and contrasted between the groups by means of ANOVA followed by post-hoc Least Significant Difference or Dunnett's tests for continuous variables and chi-square tests followed by partitioned chi-square tests for categorical variables. RESULTS: OCD-Ch and OCD-Wa did not differ on most demographic and clinical features, the only exception being the number of different types of obsessions, which were significantly higher in the former group. The OCD-CW group was more likely to exhibit an insidious onset of obsessive-compulsive symptoms, to manifest itself as a mixed subtype of obsessive-compulsive disorder and to display obsessions with contamination themes. On the other hand, the OCD non-CW group was more likely to exhibit an acute onset, a shorter duration of illness, obsessions with religious themes, an episodic course, and less severe obsessive-compulsive symptoms. CONCLUSIONS: In our sample, the probing of the presence of checking and/or washing compulsions has provided significant empirical support to establish valid subtypes of obsessive-compulsive disorder.

Demographic and clinical features of schizoaffective (schizobipolar) disorder--a 5-year retrospective study. Support for a bipolar spectrum disorder.

BACKGROUND: Schizobipolar disorder is considered related to both schizophrenia and bipolar disorder. We aimed to describe with retrospective methodology the demographic, clinical, and treatment features in a group of schizobipolar disorder patients who have been treated for at least a 5-year period and compare them with bipolar I and schizophrenic patients who were treated during the same period. METHOD: We compared the demographic and clinical data of 61 schizobipolar, 57 bipolar I, and 55 schizophrenic outpatients who were diagnosed and treated for at least 5 years in the outpatient clinic in the Federal University of Rio de Janeiro. RESULTS: The schizobipolar disorder patients had a profile similar to the bipolar I patients but are significantly different from schizophrenic patients in educational level, marital status, occupation, drug and alcohol abuse episodes, presence of depressive, mixed and maniac episodes, family history of bipolar I and mood disorders, and use of medications. Only the age of onset, suicide attempts, and family history of suicide are not significantly different among the groups. The schizophrenic patients used antipsychotics for more days and the schizobipolar and bipolar I used more antidepressants and mood stabilizers. 37 (60.6%) schizobipolar patients had their diagnosis changed to bipolar disorder by their physician in different periods during the period studied. LIMITATIONS: It is a retrospective data description based on a naturalistic treatment. The family history was collected from the patient and whenever possible from one first-degree relative. CONCLUSION: Schizobipolar disorder patients have demographic, clinical and therapeutic features similar to bipolar I patients and data support its definite inclusion in the bipolar spectrum group.

Low-resolution electromagnetic tomography and treatment response in obsessive-compulsive disorder.

We investigated whether findings from pretreatment low-resolution electromagnetic tomography (LORETA) predicted response to drug treatment in patients with obsessive-compulsive disorder (OCD). The 3D intra-cerebral distribution of neuronal electrical activity from the scalp-recorded potential distribution of 17 drug-free patients with OCD was assessed with LORETA. They were treated with antidepressants in the maximum tolerated doses for at least 12 wk. Individuals were considered to be treatment responders if they displayed a reduction of at least 35% on the initial YBOCS scores and had a final CGI score of 1 or 2. The SPM-99 t test for independent samples was employed to compare, voxel-by-voxel, the brain electrical activities of responders (n = 10) and non-responders (n = 7). Responders exhibited significantly lower activities in beta band in the rostral anterior cingulate [Brodmann's area (BA) 24 and 32] (p = 0.002) and the medial frontal gyrus (BA 10) (p = 0.002), suggesting that a distinctive pattern of activity within the medial surface of the frontal lobe predicts therapeutic response in OCD.

Do social anxiety disorder patients belong to a bipolar spectrum subgroup?

BACKGROUND: It has been proposed that all forms of bipolar disorder-perhaps all primary affective disorders-are best conceptualized as a spectrum of related illness, clinically overlapping but not necessarily genetically uniform illnesses. We aim to describe with retrospective methodology the demographic, clinical, and therapeutic response in a group of social anxiety disorder (SA) patients who improves while taking antidepressants and compare them with bipolar II (B-II) patients. METHODS: 57 SA outpatients (DSM-IV) were diagnosed and naturalistic efficacious treated with selective serotonin reuptake inhibitors (SSRI). Their demographic, clinical features and therapeutic response were compared with 41 DSM-IV bipolar II patients in their starting evaluations in our outpatient clinic in the Federal University of Rio de Janeiro, Brazil. RESULTS: There is a sub-group of SA patients who improves while taking antidepressants and presents a clear hypomanic phase. Their improvement is identical to a mild/moderate hypomanic state. Without the antidepressant, the symptoms of SA return. The SA and B-II patients have a similar number of previous depressive episodes, alcohol abuse, suicide attempts, and family history for mood disorder. LIMITATIONS: It is a retrospective data description based on a naturalist follow-up. CONCLUSION: Some SA patients have demographic, clinical and therapeutic features similar to B-II patients and they might just be a Bipolar-III sub-group with a higher level of complains to social situations and without spontaneous hypomania during lifetime.

Citalopram plus reboxetine in treatment-resistant obsessive-compulsive disorder.

While serotonin reuptake inhibitors (SRIs) are the first-line treatment of obsessive compulsive disorder (OCD), as many as 40-60% of patients fail to respond to adequate trials with these drugs. In this study, we describe the case of a patient with an SRI-resistant OCD who was successfully treated with a combination of citalopram (a selective SRI) and reboxetine (a selective noradrenaline reuptake inhibitor (SNRI)). This report suggests that future studies accessing the efficacy of the SRI SNRI combination in treatment resistant OCD are needed.

Obsessions with aggressive content emerging during the course of panic disorder: a different subtype of obsessive-compulsive disorder?

We report the clinical and therapeutic features of three patients with an obsessive-compulsive syndrome that emerged during the course of panic disorder. The DSM-IV criteria for panic disorder places central attention on the patient's phobic responses to the panic attacks and their perceived consequences. These phobic responses may develop into a syndrome that closely resembles obsessive-compulsive disorder (OCD) but typically responds to conventional anti-panic approaches. Our cases suggest that patients with OCD should be probed for an underlying panic disorder. This 'panic disorder-related subtype of OCD' may be associated with an excellent treatment response and increased rates of remission.

Impulse control disorders in patients with obsessive-compulsive disorder.

The purpose of the present paper was to identify the rate of prevalence of impulse control disorders (ICD) in patients with obsessive-compulsive disorder (OCD) and to compare patients with OCD with and without ICD with regard to sociodemographic, clinical and prognostic characteristics. Forty-five patients with OCD were assessed by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (4th edn, DSM-IV) plus additional modules for the assessment of ICD and examined using the Yale-Brown Obsessive-Compulsive Scale, the Clinical Global Impression, the Beck Depression Inventory, the Hamilton Depression Rating Scale, and the Global Assessment of Functioning. These patients were treated with serotonin re-uptake inhibitors (SRI) and followed for a variable period of time. Individuals with ICD (here defined as including not only the impulse control disorders not elsewhere classified of the DSM-IV, but also other disorders in which impulse control is a prominent feature such as alcohol and drug dependence, paraphilias and bulimia nervosa/binge eating disorder) were compared to those without ICD using the Mann-Whitney U-test and the Pearson's goodness of fit chi2 test. Sixteen patients with OCD (35.5%) displayed comorbid ICD. Patients with ICD were characterized by a significantly earlier age at OCD onset (P=0.04), a more insidious appearance of OCD symptoms (P=0.04), a higher rate of comorbid anxiety disorders (P=0.03), a greater number (P=0.02) and severity of compulsive symptoms (P=0.04), an increased rate of counting compulsions (P=0.02), and a higher number of required SRI trials (P=0.01). When OCD is found in association with ICD, the clinical picture is characterized by a greater severity of the obsessive-compulsive symptoms at presentation and by the requirement of a greater number of therapeutic attempts during follow up.

Comparison of the effects of mirtazapine and fluoxetine in severely depressed patients.

INTRODUCTION: Depression is a major global problem associated with large medical, sociological and economic burdens. Mirtazapine (Remeron, Organon NV, The Netherlands) is an antidepressant with a unique mechanism of action that has similar or superior efficacy to TCAs and SSRIs in moderate-to-severe depression. However, this agent has not yet been tested in patients with severe depression alone. OBJECTIVE: To compare the antidepressant efficacy and tolerability of mirtazapine and fluoxetine and their effects on anxiety and quality of life in patients with severe depression (> or = 25 points on the first 17 items of the Hamilton Depression Rating Scale [HDRS-17]). METHODS: In this double-blind study, 297 severely depressed patients were randomised to receive mirtazapine 15-60 mg/day (n = 147) or fluoxetine 20-40 mg/day (n = 152) for 8 weeks. 294 subjects were actually treated and 292 included in the intent-to-treat population. Symptom severity was measured by the HDRS-17, Montgomery-Asberg Depression Rating Scale (MADRS) and Clinical Global Impression (CGI) rating scale. Quality of life was self-assessed by patients using the Leeds Sleep Evaluation Questionnaire and the Quality of Life, Enjoyment and Satisfaction Questionnaire. Adverse events were recorded throughout the study. RESULTS: No statistically significant differences were noted between the two groups in change from baseline HDRS-17 score at any time point; both treatments were associated with large (approximately 15 points) decreases by study end. However, more mirtazapine-treated patients tended to exhibit a > or = 50% decrease in HDRS score (significant at day 7; 9.0% vs 0.7%, p = 0.002). Significant differences in favour of mirtazapine were also observed at day 14 for changes in MADRS scores (-10.9 vs -8.5, p = 0.006) and the proportion of patients with > or = 50% decrease in MADRS score (21.4% vs 10.9%, p = 0.031). On the CGI, the proportion of 'much/very much improved' patients tended to be greater with mirtazapine (significant at day 7; 9.7% vs 3.4%, p = 0.032). No significant between-group differences were observed for the majority of quality-of-life measures. However, mirtazapine produced significantly better improvements on 'sleeping assessment 1' (14.9 +/- 5.2 vs 13.7 +/- 5.4, p = 0.028) and 'sleeping assessment 2' (p = 0.013) than fluoxetine. Both agents were generally well tolerated but mirtazapine-treated patients experienced a mean weight gain of 0.8 +/- 2.7 kg compared with a mean decrease in weight of 0.4 +/- 2.1 kg for fluoxetine-treated patients (p < 0.001). CONCLUSIONS: Mirtazapine is as effective and well tolerated as fluoxetine in the treatment of patients with severe depression.

Clonidine in respiratory panic disorder subtype.

OBJECTIVE: Clonidine, which inhibits locus coeruleus discharge, would seem for theoretical reasons to be a good antipanic drug. Panic disorder (PD) presents a heterogeneous cluster of symptoms and a classification based on subtypes has been suggested and the respiratory symptoms group appears as a distinct subtype. METHOD: We report three cases of respiratory PD patients who were successfully treated with clonidine. RESULTS: Patients obtained panic free status, reduced anxiety levels and better functioning after clonidine administration (0.30-0.45 mg/day) for 6 weeks. CONCLUSION: Clonidine can be effective in the treatment of respiratory PD. This drug might play a role in relieving symptoms of anxiety due to noradrenergic hyperactivity in these patients.

Asperger Syndrome, obsessive-compulsive disorder, and major depression in a patient with 45,X/46,XY mosaicism.

BACKGROUND: Although previous reports have described the association of autism, mental retardation, and schizophrenia with a missing Y chromosome, we are not aware of any case showing an association between this particular chromosomal abnormality and Asperger syndrome. METHOD: We report the case of a male patient with a combination of Asperger syndrome, obsessive-compulsive disorder and 45,X/46,XY mosaicism. During the follow-up, this individual has also developed a severe episode of major depression, which was successfully treated with electroconvulsive therapy. RESULTS: To the best of our knowledge, this is the first case in which a 45,X/46,XY mosaicism was described in association with Asperger syndrome, either alone or associated with other psychiatric disorders. Diagnostic and therapeutic aspects of this unique case are presented and discussed. CONCLUSIONS: Our findings suggest that a missing Y chromosome may play an etiological role in some cases of Asperger syndrome.
