Genome-wide DNA methylation profiling in anorexia nervosa discordant identical twins.

Up until now, no study has looked specifically at epigenomic landscapes throughout twin samples, discordant for Anorexia nervosa (AN). Our goal was to find evidence to confirm the hypothesis that epigenetic variations play a key role in the aetiology of AN. In this study, we quantified genome-wide patterns of DNA methylation using the Infinium Human DNA Methylation EPIC BeadChip array ("850 K") in DNA samples isolated from whole blood collected from a group of 7 monozygotic twin pairs discordant for AN. Results were then validated performing a genome-wide DNA methylation profiling using DNA extracted from whole blood of a group of non-family-related AN patients and a group of healthy controls. Our first analysis using the twin sample revealed 9 CpGs associated to a gene. The validation analysis showed two statistically significant CpGs with the rank regression method related to two genes associated to metabolic traits, PPP2R2C and CHST1. When doing beta regression, 6 of them showed statistically significant differences, including 3 CpGs associated to genes JAM3, UBAP2L and SYNJ2. Finally, the overall pattern of results shows genetic links to phenotypes which the literature has constantly related to AN, including metabolic and psychological traits. The genes PPP2R2C and CHST1 have both been linked to the metabolic traits type 2 diabetes through GWAS studies. The genes UBAP2L and SYNJ2 have been related to other psychiatric comorbidity.

INTRODUCTION: Little work has been done on the contents of psychiatric consultancies in prisons. AIMS: To explore the sociodemographic, clinical and treatment profile of the patients who were assessed in the psychiatric consultancy of three prisons. METHODS: This is a prospective, longitudinal, descriptive and multicenter-based epidemiological study of patients who were assessed in the psychiatric consultacy of three prisons in the Autonomous Community of Valencia from 2009 to 2011. Sociodemographic, clinical and prison data was obtained from each patient. Their frequency was compared with Pearson's Ji² and averages with the ANOVA test or with The Kruskall-Wallis method. The probability of keeping the patients in schedule was calculated with Kaplan-Meier's curves and differences with the Mantel-Haenzsel method (Logrank) were established. A logistic regression model was designed to determine the data linked to frequent users. RESULTS: 786 patients were assessed in 2,006 visits (2.5 visits/patient). 90% were male, 88.2% Spanish and their average age was 36 years. 29.9% suffered from an infectious chronic pathology. 69.5% used some kinds of substance. 59.2% suffered from personality disorder and 11.6% from the spectrum of schizophrenia. The most frequent medical profiles were: 49.1% with anxiety disorder, 20.8% depressive disorder and 11.7% psychotic disorder. These psychotic disorders meant a greater probability of 1.5 times for maintaining in schedule. The most commonly prescribed medications were quetiapine, mirtazapine, pregabalin and diazepam. CONCLUSION: There is a high prevalence of mental disorders in prisons. It is necessary to improve the available resources to deal with these pathologies in the most effective way.

Introducción: Existen pocos trabajos sobre el contenido de las consultas psiquiátricas en las prisiones. Objetivos: Explorar el perfil sociodemográfico, clínico y de tratamiento de los pacientes valorados en la consulta psiquiátrica de tres centros penitenciarios. Métodos: Estudio epidemiológico multicéntrico, descriptivo, longitudinal, y prospectivo de los pacientes valorados en la consulta psiquiátrica de tres prisiones de la Comunidad Valenciana durante 2009, 2010 y 2011. Se obtuvieron variables clínicas, sociodemográficas y penitenciarias de cada paciente. Las frecuencias se compararon mediante la Ji2 de Pearson y las medias por el test de ANOVA o el método de Kruskall-Wallis. Se calculó la probabilidad de mantenerse en agenda psiquiátrica mediante curvas de Kaplan-Meier, estableciéndose las diferencias con el método de Mantel- Haenzsel (Logrank). Se diseñó un modelo de regresión logística para determinar las variables asociadas a hiperfrecuentación. Resultados: Se valoraron 786 pacientes en 2.006 consultas (2,5 visitas/paciente). El 90% eran varones y el 88,2% españoles, con una edad media de 36,0 años. El 29,9% tenían patología infecciosa crónica asociada. El 69,5% consume algún tipo de sustancia. El 59,2% sufría un trastorno de personalidad y el 11,6% del espectro de la esquizofrenia. Los cuadros clínicos más frecuentes fueron; 49,1% cuadros ansiosos, 20,8% depresivos y 11,7% síntomas psicóticos. Los trastornos psicóticos supusieron 1,5 veces más probabilidad (IC 95%; 1,1-1,9) de mantenerse más tiempo en agenda. Los fármacos más prescritos fueron quetiapina, mirtazapina, pregabalina y diacepam. Conclusiones: Los trastornos mentales en prisión son muy prevalentes. Es necesario potenciar los recursos disponibles para una adecuada atención de estas patologías(AU)
