Personalidad en pacientes con trastorno alimentario en función de la presencia/ausencia de comorbilidad con trastorno límite de la personalidad / Personality in patients with eating disorders depending on the presence/absence of comorbidity with borderline personality disorder

Resumen Los estudios sobre comorbilidad entre los trastornos de la conducta alimentaria (TCA) y los trastornos de la personalidad reportan tasas del 20-80%, condición que dificulta el diagnóstico y ensombrece el pronóstico, especialmente respecto a su comorbilidad con el trastorno límite de la personalidad (TLP). El objetivo de este estudio fue valorar si las alteraciones patológicas de la personalidad permiten distinguir no solo entre distintos tipos de TCA, sino además en función de su comorbilidad con el TLP. Participaron 29 pacientes con TCA, 10 con TCA comórbido con TLP [TCAc], 27 con TLP y 22 controles sanas, quienes completaron el Inventario Clínico Multiaxial de Millon (MCMI-II) y otras dos medidas, una sobre impulsividad y otra dirigida a evaluar síntomas de bulimia nerviosa (BN). El grupo TCA se caracterizó por mayor compulsividad, principalmente el subgrupo con anorexia nerviosa vs. los grupos TLP y TCAc; no obstante, estos dos últimos compartieron un amplio número de rasgos indicativos de inestabilidad emocional, y también -aunque en menor medida− con el subgrupo con BN. Los hallazgos apoyan un continuum de gravedad en función de la compulsividad-impulsividad, con importantes implicaciones etiopatogénicas, diagnósticas y psicoterapéuticas.

Abstract Studies on comorbidity between eating disorders (ED) and personality disorders yield rates of 20-80%, a condition that makes difficult the diagnosis and complicates prognosis, especially regarding their comorbidity with borderline personality disorder (BPD). The objective of this study was to assess whether pathological personality alterations make it possible to distinguish not only between different types of ED, but also in terms of their comorbidity with BPD. Participants included 29 patients with ED, 10 with comorbid ED with BPD (EDc), 27 with BPD and 22 healthy controls, who completed the Millon Multiaxial Clinical Inventory (MCMI-II), and two other measures, one on impulsivity and other aimed at assess symptoms of bulimia nervosa (BN). The ED group was characterized by greater compulsivity, mainly in the subgroup with anorexia nervosa vs. BPD and EDc groups; however, these last two groups shared many features that show emotional instability, although less that the subgroup with BN. These findings support a continuum of severity in terms of compulsivity-impulsivity, with important etiopathogenic, diagnostic and psychotherapeutic implications.

Eficacia de lamotrigina en un caso de trastorno de despersonalización resistente / The efficacy of lamotrigine in a resistant case of depersonalization disorder

Cuando sufre despersonalización, el individuo se queja espontáneamente de la vivencia de que su propia actividad mental, su cuerpo, su entorno o todos ellos, están cualitativamente transformados, de manera que se han vuelto irreales, lejanos o mecánicos. Este fenómeno está asociado frecuentemente con otros trastornos mentales, como en el caso que presentamos. Entre los muchos fármacos estudiados, ninguno ha mostrado ser el tratamiento de elección. Entre aquellos que han obtenido mejores resultados están los antagonistas de los receptores de los opioides, la combinación de inhibidores selectivos de la recaptación de la serotonina con lamotrigina, y la clorimipramina. Presentamos un caso resistente que respondió a lamotrigina (AU)

The individuals with depersonalizattion disorder suffer from a painful feeling that their body and mental experiences or the experiences of the environment seem become unreal, distant or mechanical. This phenomenon is often associated with other mental disorders, as in the case presented. Among the many psychoactive drugs studied, none of them has been shown to be the treatment of choice. Among those with which the best results are obtained are opioid receptor antagonists, the combination of selective serotonin reuptake inhibitors with lamotrigine and clorimipramine. We are presenting a resistant case that responded to lamotrigine(AU)
