Prevalence of mental disorder and impact on quality of life in inflammatory bowel disease.

INTRODUCTION: Different studies have described psychiatric comorbidities in inflammatory bowel disease (IBD) patients, but most of them focus mainly on depression and anxiety. Even though major mental disorders are considered one of the main factors that decrease quality of life (QoL), its role in IBD patients remains unclear. We sought to identify the prevalence of different mental disorders as well as its relationship with QoL. PATIENTS AND METHODS: Subjects were recruited from the IBD Clinic. IBD Questionnaire 32 and structured clinical interview (SCID) for DMS-IV Text Revision were applied. Demographic and clinical data were collected via self-report questionnaires and medical records. The correlation between mental disorders and QoL (IBDQ-32 score) was evaluated using the Spearman correlation test. RESULTS: In all, 104 patients were recruited, 12 with Crohn's disease, and 92 with ulcerative colitis. The prevalence of any major mental disorder was 56.7%: anxiety (44.2%), mood (27.9%), substance use (12.2%), and other psychiatric diagnoses (17.3%), and 29.8% of the patients presented three or more comorbid diagnoses. Mental Disorder (p=0.005), mood disorder (p=0.004), anxiety disorder (p=0.009), were found to be significantly associated with lower QoL. Substance use disorder was associated with lower Digestive QoL (p=0.01). Major depressive disorder (p=0.004), social phobia (p=0.03), PTSD (p=0.02), and Generalized Anxiety Disorder (p<0.001), were found to be significantly associated with lower QoL. CONCLUSIONS: IBD patients had important psychiatric comorbidity that significantly affects their QoL. These results warrant a systematic evaluation of psychiatric conditions in IBD patients.

Introducción: La comorbilidad psiquiátrica ha sido descrita en Enfermedad Inflamatoria Intestinal (EII), pero la mayoria de los reportes sólo se enfocan en la depresión y ansiedad. Los trastornos mentales son considerados uno de los principales factores que disminuyen la Calidad de Vida (CV), pero el papel que tienen en EII es hasta el momento incierto. Identificamos la prevalencia de diferentes trastornos mentales y su relación con la CV. Pacientes y métodos: Los pacientes fueron reclutados de la clínica de EII. El cuestionario IBDQ-32 y la Entrevista Clínica Estructurada (SCID) para los trastornos mentales del DSM IV Texto Revisado fueron aplicados. Variables sociodemográficas y clínicas fueron obtenidas por cuestionarios autoaplicados y expedientes clínicos. Se correlacionó los trastornos mentales y la CV utilizando la prueba de Correlación de Spearman. Resultados: Se incluyeron 104 pacientes, 12 con Enfermedad de Crohn y 92 con colitis ulcerativa. La prevalencia global de trastornos mentales fue 56.7%: ansiedad (44.2%), afecto (27.9%), uso de sustancias (12.2%) y otros trastornos mentales (17.3%). De ellos 29.8% presentaron 3 o más trastornos comórbidos. Se identificó a los trastornos mentales (p=0.005), trastornos afectivos (p=0.004), trastornos ansiosos (p=0.009), asociados significativamente con menor CV. Los trastornos por uso de sustancias estuvieron asociados a menor CV-digestiva (p=0.01). Depresión mayor (p=0.004), fobia social (p=0.03), PTSD (p=0.02), ansiedad generalizada (p<0.001), se asociaron a menor CV. Conclusiones: Los pacientes con EII tienen elevada comorbilidad psiquiátrica, la cual afecta su CV. Estos resultados justifican la evaluación sistemática de las condiciones psiquiátricas.(AU)
