Obsessive-compulsive disorder (OCD) is a prevalent psychiatric disorder of unknown etiology. However, there is some evidence that the immune system may play an important role in its pathogenesis. In the present study, two polymorphisms (rs1800795 and rs361525) in the promoter region of the cytokine tumor necrosis factor-alpha (TNFA) gene were genotyped in 183 OCD patients and in 249 healthy controls. The statistical tests were performed using the PLINK® software. We found that the A allele of the TNFA rs361525 polymorphism was significantly associated with OCD subjects, according to the allelic χ² association test (p=0.007). The presence of genetic markers, such as inflammatory cytokines genes linked to OCD, may represent additional evidence supporting the role of the immune system in its pathogenesis.

OBJECTIVE: To describe a protocol that was based on an integrative neurobiological model of scientific investigation to better understand the pathophysiology of obsessive-compulsive disorder and to present the clinical and demographic characteristics of the sample. METHOD: A standardized research protocol that combines different methods of investigation (genetics, neuropsychology, morphometric magnetic resonance imaging and molecular neuroimaging of the dopamine transporter) obtained before and after treatment of drug-naïve adult obsessive-compulsive disorder patients submitted to a sequentially allocated 12-week clinical trial with a selective serotonin reuptake inhibitor (fluoxetine) and group cognitive-behavioral therapy. RESULTS: Fifty-two treatment-naïve obsessive-compulsive disorder patients entered the clinical trial (27 received fluoxetine and 25 received group cognitive-behavioral therapy). At baseline, 47 blood samples for genetic studies, 50 neuropsychological evaluations, 50 morphometrical magnetic resonance images and 48 TRODAT-1 single-photon emission computed tomography (SPECT) exams were obtained. After 12 weeks, 38 patients completed the protocol (fluoxetine = 20 and GCBT = 18). Thirty-eight neuropsychological evaluations, 31 morphometrical magnetic resonance images and 34 TRODAT-1 SPECT exams were obtained post-treatment. Forty-one healthy controls matched for age, gender, socioeconomic status, level of education and laterality were submitted to the same research procedures at baseline. CONCLUSION: The comprehensive treatment response protocol applied in this project allowing integration on genetic, neuropsychological, morphometrical and molecular imaging of the dopamine transporter data in drug-naïve patients has the potential to generate important original information on the neurobiology of obsessive-compulsive disorder, and at the same time be clinically meaningful.OBJETIVO: Descrever um protocolo integrativo de investigação neurobiológica para melhor compreender as bases patofisiológicas do transtorno obsessivo-compulsivo e apresentar as características clínicas e demográficas da amostra. MÉTODO: Protocolo padronizado que combina diferentes modalidades de investigação (genética, neuropsicologia, ressonância magnética cerebral e imagem molecular do transportador de dopamina) obtidas antes e depois do tratamento em pacientes com transtorno obsessivo-compulsivo nunca expostos à medicação submetidos a um ensaio clínico comparando um inibidor seletivo da recaptação de serotonina (fluoxetina) e terapia cognitivo-comportamental em grupo. RESULTADOS: Cinquenta e dois pacientes com transtorno obsessivo-compulsivo entraram no ensaio clínico (27 no grupo fluoxetina e 25 no grupo de terapia). No início, foram realizadas 47 coletas de sangue para genética, 50 avaliações neuropsicológicas, 50 ressonâncias magnéticas cerebrais e 48 exames de tomografia computadorizada por emissão de fóton único (SPECT) com TRODAT-1. Depois de 12 semanas, 38 pacientes terminaram o protocolo (20 no grupo de fluoxetina e 18 no grupo de terapia). Trinta e oito reavaliações neuropsicológicas, 31 ressonâncias magnéticas de crânio e 34 exames de SPECT foram obtidos após o tratamento. Quarenta e um controles pareados foram submetidos ao mesmo protocolo inicial. CONCLUSÃO: Os dados genéticos, neuropsicológicos, volumétricos e moleculares do transportador de dopamina aliados à resposta a tratamento podem tanto gerar informações importantes a respeito da neurobiologia do transtorno obsessivo-compulsivo quanto ter uma aplicação clínica.

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.OBJETIVO: Evidências advindas de estudos de família e de genética molecular têm dado suporte à hipótese do envolvimento de mecanismos imunológicos na fisiopatologia do transtorno obsessivo-compulsivo. Tem sido sugerido que o potencializador do fator nuclear do polipeptídeo kappa light em células-B inibidoras-like 1 (NFKBIL1) é um modulador do sistema imunológico. Dada a importância do NFKBIL1 na resposta imunológica, o presente estudo investigou o polimorfismo -62A/T (rs2071592), localizado na região promotora de seu gene, como fator de risco genético para o desenvolvimento do transtorno obsessivo-compulsivo. MÉTODO: O polimorfismo -62A/T do gene do NFKBIL1 foi investigado em uma amostra de 111 pacientes com o diagnóstico de transtorno obsessivo-compulsivo, de acordo com os critérios do DSM-IV, e 272 controles saudáveis emparelhados por idade e gênero. RESULTADOS: Não houve diferenças na distribuição genotípica entre pacientes e controles (χ2 = 0,98; 2 d.f.; p = 0,61). DISCUSSÃO: Apesar dos resultados negativos, estudos compreendendo mais polimorfismos no gene do NFKBIL, em amostras maiores, são necessários. Populações com diferentes origens étnicas também precisam ser avaliadas. CONCLUSÃO: Os resultados da presente investigação não evidenciam associação entre o polimorfismo -62A/T do gene do NFKBIL1 e o transtorno obsessivo-compulsivo nesta amostra brasileira.

ObjectiveObsessive-compulsive disorder (OCD) is a common and debilitating psychiatric illness. Although a genetic component contributes to its etiology, no single gene or mechanism has been identified to the OCD susceptibility. The catechol-O-methyltransferase (COMT) and monoamine oxidase A (MAO-A) genes have been investigated in previous OCD studies, but the results are still unclear. More recently, Taylor (2013) in a comprehensive meta-analysis of genetic association studies has identified COMT and MAO-A polymorphisms involved with OCD. In an effort to clarify the role of these two genes in OCD vulnerability, a family-based association investigation was performed as an alternative strategy to the classical case-control design.MethodsTransmission disequilibrium analyses were performed after genotyping 13 single-nucleotide polymorphisms (eight in COMT and five in MAO-A) in 783 OCD trios (probands and their parents). Four different OCD phenotypes (from narrow to broad OCD definitions) and a SNP x SNP epistasis were also analyzed.ResultsOCD, broad and narrow phenotypes,were not associated with any of the investigated COMT and MAO-A polymorphisms. In addition, the analyses of gene-gene interaction did not show significant epistatic influences on phenotype between COMT and MAO-A.ConclusionsThe findings do not support an association between DSM-IV OCD and the variants of COMT or MAO-A. However, results from this study cannot exclude the contribution of these genes in the manifestation of OCD. The evaluation of broader spectrum phenotypes could help to understand the role of these and other genes in the pathophysiology of OCD and its spectrum disorders.

- Abstract
INTRODUÇÃO: O caráter familial do transtorno obsessivo-compulsivo (TOC) já é bem estabelecido. O gene da catecol O-metiltransferase (COMT) vem sendo objeto de estudo na genética de transtornos mentais, como o TOC. No caso deste transtorno, os resultados de estudos de associação com o gene da COMT são, em sua maioria, contraditórios. Meta-análises prévias, todas elas conduzidas com limitações metodológicas, encontraram achados também divergentes. Nesta tese, foram realizadas: uma revisão sistemática da literatura sobre estudos de associação baseados em famílias envolvendo o polimorfismo Val158Met do gene da COMT e o TOC e duas meta-análises, uma convencional e outra bayesiana, a fim de sintetizar os achados sobre este tema. MÉTODOS: Este trabalho seguiu o protocolo para revisão sistemática e meta-análise da Rede de Epidemiologia Genética Humana (HuGE). A busca por estudos de associação baseados em famílias foi feita em cinco bases de dados eletrônicas, assim como foram pesquisados estudos não publicados, dentre os quais um estudo ainda inédito, liderado pela autora desta tese. A meta-análise convencional foi calculada com o auxílio do programa STATA V. 11 e a bayesiana a partir da média das verossimilhanças. Foram investigados os viéses de publicação, heterogeneidade, além de análise de sensibilidade e metarregressão. RESULTADOS: O estudo original, que contou com 83 trios, conduzido pela autora desta tese, não encontrou associação entre COMT e TOC. Este estudo, em conjunto com mais oito estudos (seis estudos publicados e dois não publicados), foram incluídos na meta-análise. As meta-análises com método convencional e bayesiano não encontraram associação entre o polimorfismo Val158Met do COMT e o TOC na amostra total, nem nas amostras separadas por gênero. CONCLUSÕES: Contrariando meta-análises prévias, os achados deste estudo não demonstraram associação entre COMT e TOC. No entanto, a participação do gene da COMT em subgrupos específicos do TOC e em seus endofenótipos de risco ainda merece ser investigada BACKGROUND: Obsessive-compulsive disorder (OCD) has long been considered a familial disorder. The catechol-O-methyltransferase gene has been studied in several mental disorders, including OCD. Particularly in this disorder, the findings of an association between COMT and OCD are inconclusive. Previous meta-analyses, which were conducted with several methodological limitations, found conflicting results. This work comprises: a systematic literature review regarding family-based association studies involving the COMT Val158Met polymorphism and OCD, and two metaanalyses, a conventional and a Bayesian meta-analysis, to summarize the findings on this subject. METHODS: This study was performed according to the Human Genome Epidemiology network (HuGE) guidelines for systematic review and meta-analysis. The search for family-based association studies were conducted in five electronic databases and in sources from unpublished studies. An original unpublished study, led by the author of this thesis, was included in the meta-analysis. The conventional meta-analysis was calculated with the STATA V.11 software and the Bayesian meta-analysis through the likelihood mean. Publication bias and heterogeneity were investigated. Sensitivity analysis and meta-regression were also performed. RESULTS: The original study with 83 OCD trios, conducted by the author of this thesis, found no association between COMT and OCD. This study, together with eight other studies (six studies being published and two unpublished), were included in the meta-analysis. Meta-analyses with the conventional and Bayesian method found no association between the COMT Val158Met polymorphism and OCD in the total, female-only or male-only samples. CONCLUSIONS: Different from previous meta-analyses, this study does not support the association between COMT and OCD. However, the involvement of the COMT gene in specific subgroups of OCD or endophenotypes associated with a risk for OCD should be further investigated

Schizophrenic patients present a higher risk for the development of hyperglycemic disorder and the use of antipsychotic drugs seems to increase the risk of diabetes mellitus. The present review concerns the relation between atypical antipsychotic drugs and the risk of developing diabetes mellitus. A Medline and Webofscience search was performed by using the terms "Hyperglycemia", "Diabetes Mellitus" and "Antipsychotic Agents", to identify original papers and reviews published between 1997 and september 2002. It is concluded that there is a higher risk of glycemic disorders in the population of patients treated by antipsychotic drugs. Dietetic measures and attention to risk factors should be taken into account during the treatment of psychotic patients.

Acute infantile diarrhea is an important problem in public healthcare and Rotaviruses are responsible for about 20-40% of the cases of severe dehydrating diarrhea in children at 0-5 years old. In this work, we have analyzed diarrheic feces from children at 0-4 years old hospitalized between October 1998 and December 1999, in Salvador, Bahia, Brazil. In order to detect rotavirus, the samples were analyzed by ELISA (Test-Pack Abbot) and SDS-PAGE tests. The results demonstrated that from the 217 samples tested, 76 (35%) were positive, 127 (58,5 %) were negative and 14 (6,5%) diverged in both tests. The positive samples analyzed by SDS-PAGE test revealed the group A rotavirus and they were classified as short eletropherotypes (Subgroup I) and long eletropherotypes (Subgroup II).
