Childhood trauma determines different clinical and biological manifestations in patients with eating disorders

There is a significant relationship between childhood trauma and the development of an eating disorder in adolescence or adulthood, possibly influenced by circulating levels of inflammatory parameters. The main objective is to identify and describe a subgroup of patients with eating disorders and a history of trauma in childhood or adolescence with differential clinical features.

An observational study on a sample of 55 patients who met the diagnostic criteria for any DSM-5 eating disorder was carried out. Inflammatory parameters in white blood cells were examined. Patients underwent different assessments, including clinical and personality scales.

Patients with a history of trauma had higher scores in the delirious and narcissistic items of the Millon Clinical Multiaxial Inventory (MCMI-II) (p < 0.05) and a higher score in the paranoid item of the SCID-5 Personality Disorders Version (SCID-5-PD) (p < 0.05). Patients with distinguishing personality features were grouped according to the Childhood Trauma Questionnaire sexual subscale. Tumor necrosis alpha (TNF-α) showed a significant association with childhood trauma history.

There is a profile of patients with eating disorders who have increased activity in the inflammatory pathways that, if identified precociously, can benefit from specifically aimed interventions.
