title: [Influence of interleukin-1 beta gene polymorphism and childhood maltreatment on antidepressant treatment].
abstract: OBJECTIVE
  To explore the influence of interleukin-1 beta (IL1B) gene polymorphism and childhood maltreatment on antidepressant treatment.
  
  
  METHODS
  Two hundred and four patients with major depressive disorder (MDD) have received treatment with single antidepressant drugs and were followed up for 8 weeks. Hamilton depression scale-17 (HAMD-17) was used to evaluate the severity of depressive symptoms and therapeutic effect. Childhood maltreatment was assessed using Childhood Trauma Questionnaire, a 28-item Short Form (CTQ-SF). Single nucleotide polymorphism (SNP) of the IL1B gene was determined using a SNaPshot method. Correlation of rs16944 gene polymorphism with response to treatment was analyzed using Unphased 3.0.13 software. The main and interactive effects of SNP and childhood maltreatment on the antidepressant treatment were analyzed using Logistic regression analysis.
  
  
  RESULTS
  No significant difference of gender, age, year of education, family history, episode time, and antidepressant agents was detected between the remitters and non-remitters. Association analysis has found that the SNP rs16944 in the IL1B AA genotype carriers antidepressant response was poorer (χ2=3.931, P=0.047). No significant difference was detected in the CTQ scores between the two groups. Genetic and environmental interaction analysis has demonstrated a significant correlation between rs16944 AA genotype and childhood maltreatment and poorer response to antidepressant treatment.
  
  
  CONCLUSIONS
  The SNP rs16944 in the IL1B gene and its interaction with childhood maltreatment may influence the effect of antidepressant treatment for patients with MDD.
