Serum lipid concentrations in Croatian veterans with post-traumatic stress disorder,post-traumatic stress disorder comorbid with major depressive disorder,or major depressive disorder.

The aim of this study was to assess eventual differences in serum cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, LDL-C/HDL-C ratio between veterans with combat-related post-traumatic stress disorder (PTSD) only or comorbid with major depressive disorder (MDD), veterans with combat experiences with MDD, and healthy control group. PTSD and/ or MDD were diagnose according to structured clinical interview based on DSM-IV criteria. Additional criteria to diagnose PTSD were Clinician Administered PTSD Scale (CAPS), and to diagnose MDD Montgomery-Asberg Depression Rating Scale (MADRAS). Serum lipid concentrations were determined by using the enzyme-assay method. Veterans with combat-related PTSD as well as veterans with combat-related PTSD comorbid with MDD showed significantly higher concentrations of cholesterol (F=9.858, p<0.01), triglycerides (F=10.112, p<0.01), LDL-C (F=11.145, p<0.01), and LDL-C/HDL-C ratio (F=8.346, p<0.01) vs. veterans with MDD or healthy control group. Contrary healthy control group and veterans with MDD showed significantly higher concentrations of HDL-C (F=8.421, p<0.01), vs. veterans with PTSD or PTSD comorbid with MDD. In conclusion, there are no differences in serum lipid concentrations between veterans with combat-related PTSD and PTSD comorbid with MDD, but they have higher lipid concentrations than veterans with MDD or healthy control subjects.
