Dehydroepiandrosterone Sulfate Cortisol and Adrenocorticotropic Hormone Levels in Drug-Naive First Episode Male and Female Patients With Psychosis

摘要

Introduction: Impaired response to stress and a pathological activation of the hypothalamic-pituitary-adrenal axis have been implicated in the pathophysiology of schizophrenia. We aimed to measure serum dehydroepiandrosterone sulfate (DHEA-S), cortisol and adrenocorticotropic hormone (ACTH) levels in drug-naïve, first episode patients with psychosis followed-up in a Greek tertiary center. Methods: Data were included from drug-naïve, first episode patients with psychosis and controls matched for age and sex. Serum DHEA-S, cortisol and ACTH levels were recorded. Results are reported as mean (standard deviation, range). Paired t-test or Wilcoxon signed rank test were performed for group comparisons. The level of significance was set at p less than 0.05. Statistical analysis was performed with Stata 15.1. Results: Data were included for 110 subjects (70 men, 40 women); 55 patients and 55 controls. Mean age was 31.3 years (8.7, 18.0-48.0) in patients and 31.4 years (8.9, 17.0-49.0) in controls. Serum DHEA-S was higher in patients [306.5 μg/dl (165.4, 70.0-790.0)] compared to controls [240.1 μg/dl (113.5, 46.0-597.0)] (p=0.011). Serum ACTH was similar between patients and controls [28.5 pg/ml (15.7, 6.2-73.9) versus 26.5 pg/ml (15.3, 7.0-70.5), p=0.636]. Serum cortisol levels and cortisol/DHEA-S ratio were statistically lower in patients [12.6 μg/dl (4.5, 3.5-24.5) and 5.3 (3.6, 1.3-19.5), respectively] compared to controls [15.5 μg/dl (4.9, 4.2-30.1) and 8.0 (4.7, 1.1-25.5), respectively] (p=0.007 and 0.001, respectively). Sub-analysis, revealed that in men, serum DHEA-S was similar between patients and controls [303.7 μg/dl (149.0, 85.0-744.0) versus 275.0 μg/dl (117.4, 89.0-597.0), respectively, p=0.271) whereas in women serum DHEA-S was higher in patients compared to controls [311.4 μg/dl (194.8, 70.0-790.0) versus 179.2 μg/dl (75.9, 46.0-314.0), respectively, p=0.005]. Serum cortisol and ACTH levels were not different in the above subgroups except serum cortisol in men which was lower in patients compared to controls [12.8 μg/dl (4.4, 3.5-21.6) and 15.9 μg/dl (5.4, 4.2-30.1), respectively, p=0.027]. Conclusions: Serum DHEA-S levels were higher in drug-naïve, first episode female patients, with psychosis compared to controls. DHEA-S levels in male patients and controls were similar.
