RESUMO
AIM: Deficits in mentalization have been described in several mental disorders, but information is still scarce and ambiguous about the types of mentalization errors in each disorder and their specificity and severity in borderline personality disorder (BPD). Due to the high comorbidity between this disorder and axis I disorders, the aim of this work is to study differences in mentalization responses in BPD considering the different comorbidity profiles with other disorders. METHODS: A total of 141 BPD patients were evaluated using The Mini-International Neuropsychiatric Interview (MINI), to identify comorbid axis I disorders. Mentalizing ability was assessed by the Movie for the Assessment of Social Cognition (MASC). Statistical associations were analysed into the different variables. RESULTS: Patients with comorbid BPD and anorexia nervosa (AN), suicidal behaviour disorder or post-traumatic stress disorder (PTSD) respectively presented higher overmentalization, undermentalization and absence of mentalization errors, compared with patients with BPD without comorbidity. CONCLUSIONS: Results show that BPD comorbidity with AN, suicidal behaviour disorder and PTSD affect to the types and severity of mentalizing deficits observed in these patients. This study highlights the importance of the assessment and treatment of axis I comorbid disorders in borderline personality disorder, with the objective of shaping personalized treatment for every patient.
RESUMO
INTRODUCTION: Eating disorders (ED) represent a group of very complex and serious diagnoses characterized by emotional dysregulation and impulsivity. New approaches are necessary to achieve effective diagnosis and treatments. Shifting biomarker research away from the constraints of diagnostic categories may effectively contribute to a dimensional differentiation across disorders according to neurobiology (e.g., inflammatory biomarkers). Thus, the aim of our study was to identify inflammatory profiles in patients with ED. METHODS: A sample of 100 women with an ED (23.4 ± 8.55 years) and 59 healthy controls (HC) (20.22 ± 4.18 years) was used. K-means cluster analysis was followed to identify inflammatory clusters considering seven blood biomarkers (iNOS, TNFα, COX2, p38, ERK, TBARS and PPARγ). Moreover, a wide assessment of clinical features was conducted. RESULTS: Two distinct clusters were identified. Cluster 1 patients were characterized by higher inflammatory levels of TNF-α, COX2, p38, and ERK, and had more restrictive anorexia diagnosis than cluster 2. Cluster 2 participants showed higher inflammatory levels of iNOS and were older than cluster 1 and controls and had lower BMI than HC. In addition, they had higher levels of bulimic symptoms than those from the cluster 1 and HC, and higher impulsivity than HC. All ED patients (regardless of cluster) showed higher ED symptoms and more trauma than HC. CONCLUSIONS: Our study revealed that inflammatory dysfunction may be linked with clinical endophenotypes in ED, one more restrictive (cluster 1) with an inflammation/oxidative endophenotype more cytokine and MAPK/ERK mediated, and the other more impulsive, with more bulimic symptoms (cluster 2) with NO free radical high output source iNOS. Trauma seems to be a vulnerability factor for both endophenotypes.

Interpersonal difficulties in borderline personality disorder (BDP) have been suggested to be related to impairments in Social Cognition (SC), mainly due to deficits in Theory of Mind (ToM). However, literature is scarce and ambiguous. This work aims to study the SC impairments in BPD patients, by the specific assessment of ToM deficits, and to investigate the relationship between these SC impairments and clinical variables. 82 BPD patients with BPD and 47 control subjects were assessed with the Movie for the Assessment of Social Cognition (MASC). Clinical variables of severity, chronicity, functionality and anxious-depressive symptomatology were recorded. BPD patients had fewer correct mentalization responses and more overmentalization, undermentalization, and absence of mentalization errors than controls. Chronicity was negatively correlated with overmentalization and positively correlated with undermentalization and absence of mentalization errors. Functionality was indirectly correlated with absence of mentalization. These results confirm previous reports of alterations in SC in BPD patients. Furthermore, this study shows that SC impairments in patients with BPD are dependent on characteristics such as chronicity or degree of functionality. The different ToM profiles in patients with BPD indicate the necessity of developing variants of mentalization therapy depending on the deficits of each patient.
