We investigated stability and change of plasma and urinary oxytocin as well as OXTR DNA methylation patterns through psychotherapy. Furthermore, we explore the potential impact of inpatient psychotherapy on oxytocin-related biomarkers and vice versa by differentiating patients who remitted from depression versus non-remitters. Blood and urine samples were taken from 85 premenopausal women (aged 19-52), 43 clinically depressed patients from a psychosomatic inpatient unit, and 42 healthy control subjects matched for age and education at two points of time. Serum and urine oxytocin was measured using standard ELISA, and DNA methylation of the OXTR gene was assessed using bisulfite sequencing at the time of admission (baseline) and at discharge and from controls at matched time points. Oxytocin plasma levels were not associated with depression and were influenced by neither time in healthy controls nor psychotherapy in patients. Non-remitting depressed patients had significantly lower oxytocin urine levels before and after psychotherapy treatment. We found significantly lower exon 1 OTXR methylation in depressed patients over time and these differences were driven by patients remitting due to psychotherapy. A reverse pattern - higher levels of methylation in remitters - was found for exon 2 OXTR DNA methylation. Plasma oxytocin, urinary oxytocin, and OXTR DNA methylation patterns were intrapersonally relatively stable. OXTR-related factors were seemingly unaffected by inpatient psychotherapeutic treatment, but we found significant differences between remitting and non-remitting patients in urinary oxytocin and OXTR DNA methylation. If replicated, this suggests that OXTR-related markers may predict inpatient treatment outcomes of clinically depressed patients.
