Family, twin and segregation analysis have provided evidences that genetic factors are implicated in the susceptibility for obsessive-compulsive disorder (OCD). Several lines of research suggest that the dopaminergic system may be involved in the pathophysiology of OCD. Thus, the aim of the present study was to investigate a possible association between a polymorphism located in intron 8 of the dopamine transporter gene (SLC6A3) and OCD in a Brazilian sample composed by 208 patients and 865 healthy controls. No statistically differences were observed in allelic and genotype distributions between cases and controls. No association was also observed when the sample was divided according to specific phenotypic features such as gender, presence of tic disorders co-morbidity and age at onset of obsessive-compulsive symptoms (OCS). Our results suggest that the intron 8 VNTR of the SLC6A3 investigated in this study is not related to the susceptibility for OCD in our Brazilian sample.

The Relationship

BackgroundObsessive–compulsive disorder (OCD) is probably an etiologically heterogeneous condition. Many patients manifest other psychiatric syndromes. This study investigated the relationship between OCD and co-morbid conditions to identify subtypes.MethodSeven hundred and six individuals with OCD were assessed in the OCD Collaborative Genetics Study (OCGS). Multi-level latent class analysis was conducted based on the presence of eight co-morbid psychiatric conditions [generalized anxiety disorder (GAD), major depression, panic disorder (PD), separation anxiety disorder (SAD), tics, mania, somatization disorders (Som) and grooming disorders (GrD)]. The relationship of the derived classes to specific clinical characteristics was investigated.ResultsTwo and three classes of OCD syndromes emerge from the analyses. The two-class solution describes lesser and greater co-morbidity classes and the more descriptive three-class solution is characterized by: (1) an OCD simplex class, in which major depressive disorder (MDD) is the most frequent additional disorder; (2) an OCD co-morbid tic-related class, in which tics are prominent and affective syndromes are considerably rarer; and (3) an OCD co-morbid affective-related class in which PD and affective syndromes are highly represented. The OCD co-morbid tic-related class is predominantly male and characterized by high conscientiousness. The OCD co-morbid affective-related class is predominantly female, has a young age at onset, obsessive–compulsive personality disorder (OCPD) features, high scores on the ‘taboo’ factor of OCD symptoms, and low conscientiousness.ConclusionsOCD can be classified into three classes based on co-morbidity. Membership within a class is differentially associated with other clinical characteristics. These classes, if replicated, should have important implications for research and clinical endeavors.

ABSTRACTIntroduction: Research suggests that obsessive-compulsive disorder (OCD) is not a unitary entity, but rather a highly heterogeneous condition, with complex and variable clinical manifestations.Objective: The aims of this study were to compare clinical and demographic characteristics of OCD patients with early and late age of onset of obsessive-compulsive symptoms (OCS); and to compare the same features in early onset OCD with and without tics. The independent impact of age at onset and presence of tics on comorbidity patterns was investigated.Methods: Three hundred and thirty consecutive outpatients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for OCD were evaluated: 160 patients belonged to the “early onset” group (EOG): before 11 years of age, 75 patients hadResults: The EOG had a predominance of males, higher frequency of family history of OCS, higher mean scores on the “aggression/violence” and “miscellaneous” dimensions, and higher mean global DY-BOCS scores. Patients with EOG without tic disorders presented higher mean global DY-BOCS scores and higher mean scores in the “contamination/cleaning” dimension.Conclusion: The current results disentangle some of the clinical overlap between early onset OCD with and without tics.

Issler CK, Monkul ES, Amaral JAMS, Tamada RS, Shavitt RG, Miguel EC, Lafer B. Bipolar disorder and comorbid obsessive-compulsive disorder is associated with higher rates of anxiety and impulse control disorders.Objective:Although bipolar disorder (BD) with comorbid obsessive-compulsive disorder (OCD) is highly prevalent, few controlled studies have assessed this comorbidity. The objective of this study was to investigate the clinical characteristics and expression of comorbid disorders in female BD patients with OCD.Method:We assessed clinically stable female outpatients with BD: 15 with comorbid OCD (BD+OCD group) and 15 without (BD/no-OCD group). All were submitted to the Structured Clinical Interview for DSM-IV, with additional modules for the diagnosis of kleptomania, trichotillomania, pathological gambling, onychophagia and skin picking.Results:The BD+OCD patients presented more chronic episodes, residual symptoms and previous depressive episodes than the BD/no-OCD patients. Of the BD+OCD patients, 86% had a history of treatment-emergent mania, compared with only 40% of the BD/no-OCD patients. The following were more prevalent in the BD+OCD patients than the BD/no-OCD patients: any anxiety disorder other than OCD; impulse control disorders; eating disorders; and tic disorders.Conclusion:Female BD patients with OCD may represent a more severe form of disorder than those without OCD, having more depressive episodes and residual symptoms, and being at a higher risk for treatment-emergent mania, as well as presenting a greater anxiety and impulse control disorder burden.

OBJECTIVE: Evidence from family and molecular genetic studies support the hypothesis of involvement of immunologic mechanisms in the pathophysiology of obsessive-compulsive disorder. The nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-like 1 (NFKBIL1) has been suggested as a modulator of the immunological system. Given the importance of NFKBIL1 in the immunological response, the present study investigated the -62A/T polymorphism (rs2071592), located in the promoter region of its gene (NFKBIL1), as a genetic risk factor for the development of obsessive-compulsive disorder. METHOD: The -62A/T NFKBIL1 polymorphism was investigated in a sample of 111 patients who met DSM-IV criteria for obsessive-compulsive disorder and 272 healthy age- and gender-matched controls. RESULTS: There were no differences in genotypic distributions between patients and controls (χ2 = 0.98; 2 d.f.; p = 0.61). DISCUSSION: Despite these negative findings, more comprehensive polymorphism coverage within the NFKBIL1 is warranted in larger samples. Populations with different ethnic backgrounds should also be studied. CONCLUSION: The results of the present investigation do not provide evidence for the association between the -62A/T NFKBIL1 polymorphism and obsessive-compulsive disorder in this Brazilian sample.

Obsessive Compulsive Disorder (OCD) is a common disorder and usually runs a chronic course with waxing and waning course. It leads to pervasive impairments in multiple domains of life. The aim of the study was to assess the demographic characteristics of the OCD patients and symptom severity of this disorder. This was a cross-sectional study done in OCD clinic of outpatient department (OPD) of BSMMU, during the period from May, 2015 to April, 2017. Four hundred patients fulfilling the inclusion and exclusion criteria were selected consecutively. After taking written consent a predetermined questionnaire was filled for each patient through face-to-face interview. Then patients were evaluated covering the following areas: Axis I diagnoses (DSM-IV) and Y-BOCS severity scale. The results showed that, the mean age of the respondents was 26.6 (SD±9.9) years, ranging from 8 to 63 years. According to Y-BOCS symptoms severity used for adult patients found that majority (70%) of the patients had moderate to severe sufferings. Male had co-morbid anxiety disorders (panic disorder, agoraphobia, social phobia) more but female patients were found more depressive disorders. Female had more hypothyroidism, diabetes, skin disorders and hypertension than male. These demographic status, co-morbidity profile and symptoms severity can serve as the baseline data for a country like Bangladesh and further large scale, multi-centered study would better generalize the study results.

Co Morbidity

Obsessive-compulsive disorder/ symptoms may be co-morbid in schizophrenia. The clinical impact of this co-morbidity is poor response to anti-psychotic medications. We present a case of 35 yr old female who presented with symptoms suggestive of schizophrenia and later co-morbid obsessive symptom responded well to addition of fluoxetine to antipsychotics. This case study reveals that the identification and treatment of OCD in schizophrenia is very crucial for optimistic outcome.
