The aim of this study is to evaluate the effects of a trauma-focused psychotherapy upon war refugees from Bosnia. Seventy refugees who met the criteria for posttraumatic stress disorder (PTSD) and somatoform disorders were included. The first 35 refugees were offered psychotherapy and the following 35 refugees received usual care. Outcome variables were changes in self-reported PTSD symptoms, psychological symptoms, and health status. At 12-month follow-up, participants in the intervention group reported significantly lower scores on the PTSD scale and the measure of psychological symptoms than the comparison group participants. Our results suggest that psychotherapy reduces symptoms of PTSD and somatoform disorders among war refugees even in the presence of insecure residence status.

During acute psychological stress, the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system are activated. The released stress hormones influence glucose metabolism, can activate immune cells, and modulate subclinical inflammation. The aim of our study was to analyze the effect of acute psychological stress on glucose metabolism and the inflammatory status in patients with post-traumatic stress disorder (PTSD). We included 15 overweight male Bosnian war refugees with PTSD into the study (mean age 44+/-11 years, BMI 29.3+/-4.3 kg/m (2)). All subjects underwent an oral glucose tolerance test (OGTT) with either acute stress (trauma script exposure) or a resting period in a cross-over design. Blood was drawn over 2.5 h and metabolic markers were measured. Systemic levels of immune markers were determined using high-sensitive ELISA or bead-based multiplex assay. Immune gene expression was quantified by RT-PCR. After being exposed to acute stress, cortisol levels and heart frequency tended to be increased. Higher blood glucose and insulin levels after stress exposure were observed (p<0.05). Systemic levels of the chemokines interferon-gamma-inducible protein-10 and macrophage chemoattractant protein-1 were decreased compared to the control day (both p<0.05) and the expression of the proinflammatory regulator IKK beta was significantly reduced after stress exposure (p<0.001). In conclusion, acute stress induces postprandial blood glucose peaks and elevated insulin levels and a selective decrease of systemic immune markers and the proinflammatory regulator of the NF kappaB cascade, which are associated with type 2 diabetes. This points towards an independent effect of acute psychological stress on glucose metabolism and inflammation.
