Differences in the association between childhood trauma history and borderline personality disorder or attention deficit/hyperactivity disorder diagnoses in adulthood.

Common environmental etiological factors between borderline personality disorder (BPD) and attention deficit/hyperactivity disorder (ADHD) have not been fully studied. The main aim of this study was to investigate the relationship between childhood trauma histories, assessed by the Childhood Trauma Questionnaire-Short Form (CTQ-SF), with adult BPD, ADHD or BPD-ADHD diagnoses. Comorbid BPD-ADHD patients exhibited significantly higher clinical severity and higher scores in the Total Neglect Scale, compared to BPD and ADHD patients, and only a marginal difference was observed for Sexual Abuse when BPD and ADHD patients were compared. Physical Trauma Scales were associated with ADHD diagnosis, whereas Emotional Abuse and Sexual Abuse Scales were associated with BPD or BPD-ADHD diagnoses. The study findings support the association between experiencing traumatic events in childhood and a higher clinical severity of BPD in adulthood. Furthermore, physical trauma history in childhood could be associated with the persistence of ADHD in adulthood and emotional or sexual abuse with later development of BPD or comorbid BPD-ADHD. Whereas experiencing childhood traumas is associated with later development of more general psychopathology, our study supports that a specific type of traumatic event could increase the risk for the consolidation of a concrete psychiatric disorder in the trajectory from childhood to adulthood of vulnerable subjects.

The role of hypothalamus-pituitary-adrenal genes and childhood trauma in borderline personality disorder.

Current knowledge suggests that borderline personality disorder (BPD) results from the interaction between genetic and environmental factors. Research has mainly focused on monoaminergic genetic variants and their modulation by traumatic events, especially those occurring during childhood. However, to the best of our knowledge, there are no studies on the genetics of hypothalamus-pituitary-adrenal (HPA) axis, despite its vulnerability to early stress and its involvement in BPD pathogenesis. The aim of this study was to investigate the contribution of genetic variants in the HPA axis and to explore the modulating effect of childhood trauma in a large sample of BPD patients and controls. DNA was obtained from a sample of 481 subjects with BPD and 442 controls. Case-control differences in allelic frequencies of 47 polymorphisms in 10 HPA axis genes were analysed. Modulation of genetic associations by the presence of childhood trauma was also investigated by dividing the sample into three groups: BPD with trauma, BPD without trauma and controls. Two FKBP5 polymorphisms (rs4713902-C and rs9470079-A) showed significant associations with BPD. There were also associations between BPD and haplotype combinations of the genes FKBP5 and CRHR1. Two FKBP5 alleles (rs3798347-T and rs10947563-A) were more frequent in BPD subjects with history of physical abuse and emotional neglect and two CRHR2 variants (rs4722999-C and rs12701020-C) in BPD subjects with sexual and physical abuse. Our findings suggest a contribution of HPA axis genetic variants to BPD pathogenesis and reinforce the hypothesis of the modulating effect of childhood trauma in the development of this disorder.

An exploratory association study of the influence of noradrenergic genes and childhood trauma in Borderline Personality Disorder.

This study investigated the possible association of 40 polymorphisms within 4 noradrenergic genes with BPD risk and the modulating effect of childhood trauma on these associations in 481 BPD subjects and 442 controls. COMT rs5993882, DBH rs77905 and SLC6A2 rs1814270 showed associations with BPD, which were modulated by childhood trauma. However, none of these findings survived Bonferroni correction. Further investigation is needed to clarify the involvement of these genes in BPD pathogenesis.

Regional analysis of health service utilisation by persons with borderline personality disorders: implications for evidence-informed policy.

BACKGROUND: Borderline Personality Disorder (BPD) has been associated with an intensive use of health resources and a high economic burden. AIMS OF THE STUDY: The aim of this study is to analyze the use of mental healthcare resources by BPD patients, to identify the information gaps on BPD at the regional health databases and to describe specific indicators and patterns of care utilization by persons with BPD in order to guide evidence-informed policy planning in Catalonia (Spain). METHODS: A multi-level cross-design synthesis approach was applied following a mixed quantitative-qualitative analysis to estimate the regional service utilisation of patients with BPD. This framing analysis included estimates based on all available data on the use of services combined with prior expert knowledge gathered through a nominal group of key stakeholders in this field. RESULTS: The estimated year prevalence of BPD was 0.7% but only 9.6% of all BPD patients in Catalonia had any contact with the health care system. Of those, less than half contacted mental health care. BPD represented 1.7% of the total care load in the community mental health centres. A significant information gap was identified in all the official databases and impeded their direct use for planning and resource allocation in BPD. Expert knowledge was required to estimate rates of care utilization at every level of care system (primary care, specialized outpatient care and hospital care). Nevertheless the high pattern of care utilization identified at the databases was accurate according to the experts. DISCUSSION: Detection of BPD was lower than expected in the local, regional and national databases and registries of Catalonia. Local data was judged highly inaccurate by experts in comparison to data available on other mental disorders in the same databases. IMPLICATIONS FOR HEALTH POLICY AND RESEARCH: Specific incentives should be implemented to improve the availability and accuracy of information on BPD at the regional databases. When present, BPD should be coded before other psychiatric disorders in clinical records and health databases. Mental health surveys and psychiatric epidemiological studies should specifically incorporate BPD in their inclusion criteria and further studies on the utilisation pattern of this disorder are needed, both locally and internationally.

Prevención del trastorno límite de la personalidad del adulto: tratamiento de los adolescentes con síntomas límites / Prevention of adult bordeline personality disorder: Treatment of adolescents with bordeline symtoms

EL TRASTORNO LÍMITE DE PERSONALIDAD (TLP) es un trastorno psiquiátrico grave y difícil de tratar de un modo adecuado en el adulto, dada su heterogeneidad clínica y la diversidad de necesidades que puede presentar. Se ha evidenciado que el diagnóstico y tratamiento precoz puede mejorar el pronóstico del TLP, al evitar las complicaciones que se asocian a los casos que han evolucionado a lo largo de la vida y que han sido diagnosticados tardíamente. Actualmente se considera el TLP como un trastorno ligado al desarrollo, existiendo un número importante de pacientes que manifiestan el trastorno completa o parcialmente ya en la adolescencia. Por todo ello, las estrategias de detección precoz durante esta etapa de la vida permitirían establecer tratamientos de menor complejidad y mayor eficiencia, evitando el desarrollo de formas más graves del trastorno en el adulto (AU)

Borderline Personality Disorder (BPD) is a serious psychiatric disorder, with a difficult treatment in the adulthood, related to its clinical heterogeneity and diversity of needs that patients can require. Evidence suggests that early diagnosis and treatment may improve BPD prognosis, to avoid complications associated with those cases that have evolved throughout life and have been diagnosed late. Nowadays, BPD is considered as a developmental disorder, existing a significant number of patients that exhibit the complete or partial disorder in the adolescence. Therefore, early detection strategies during this stage of life enable to establish treatments to reduce complexity and increase efficiency, avoiding the development of severe forms of this disorder in the adulthood (AU)
