Depression is common in hemodialysis patients. Reduced DHEA-S levels have been shown to be associated with depression in general population. Abnormalities in hormone production and metabolism are found in hemodialysis patients. However, the association between DHEA-S levels and depression in hemodialysis patients has not been established.
We conducted a cross-sectional study, in which 80 patients under regular hemodialysis were studied, and their serum DHEA-S levels were analyzed.
The prevalence of depression in our studied hemodialysis population is 37.5% (30/80). The DHEA-S level was 1138.1+/-1216.9 ng/mL in male patients and 502.1+/-389.4 ng/mL in female patients. The levels were not significantly different between patients with or without depression (910.8+/-1127.1 ng/mL vs. 769.3+/-848.3 ng/mL, P=0.533). As compared to the non-depressed patients, the depressed patients were more likely to be male, with lower body mass index, consuming more alcohol, and with more co-morbidity. The prevalence of depression was not associated with age, educational background, smoking, duration of dialysis, hemoglobin, albumin, CRP, ferritin, and urea clearance (Kt/V and URR). The serum DHEA-S levels exhibited significant and independent associations with age, gender, diabetes mellitus, and the levels of serum albumin.
The study suggested a lack of association between plasma DHEA-S levels and depression in hemodialysis patients.

    ABSTRACT: Background: Borderline personality disorder (BPD) patients display a complex and heterogeneous clinical phenotype that plausibly implies variable underlying pathogenic mechanisms. A dysregulation of peripheral benzodiazepine receptors has previously been shown in BPD peripheral tissues, implying possible alterations of its ligand, the diazepam binding inhibitor (DBI) or of the downstream products of its activation, i.e. neuroactive steroids. Methods: The aim of this work consisted in assessing, by ELISA, fasting plasma levels of DBI and dehydroepiandrosterone sulphate (DHEA-S), including cortisol and the cortisol-to-DHEA-S molar ratio (CDR), in 17 BPD adolescents versus 13 healthy controls, testing the possibility that clinical scales related to depressive or anxious traits (CDI, STAI-Y) or to disease severity (BPDCL) might be associated with a selective dysregulation of these parameters. Results: DBI plasma levels were unchanged, while DHEA-S ones were significantly increased (approx. 70%) and the CDR decreased in BPD patients. No meaningful correlations with clinical variables emerged. Conclusion: Our results indicate that a dysfunction of the neurosteroid system might be operative in BPD in spite of unchanged DBI plasma levels and that DHEA-S might represent a generalized trait marker for the altered stress response that is associated with this disorder.

    ABSTRACT: Previous evidence has shown that adrenal androgens, dehydroepiandrosterone (DHEA) and its sulfate derivative (DHEAS) have significant functions related to the control of mood, affect, and anxiety. Changes in their expression levels are reportedly related to several psychiatric disorders. The objective of this meta-analysis was to explore the role of DHEAS protein expression in patients with depression. Web of Science, Cochrane Library, CISCOM, CINAHL, Google Scholar, China BioMedicine (CBM) and China National Knowledge Infrastructure (CNKI) were electronically searched. Only those studies that analyzing DHEAS expression in depression patients were considered eligible for inclusion. Standardized mean differences (SMDs) were pooled with a 95% confidence interval (CI) in accordance with the random-effects model. Ten clinical case-control studies, consisting of 4496 subjects (493 patients with depression and 4003 healthy controls) were incorporated for analysis. Results revealed a lower DHEAS protein expression level in patients with depression than in normal controls (SMD=0.17, 95% CI: 0.06-0.27, P=0.002). Ethnicity-stratified analysis indicated that lower levels of DHEAS expression in depression patients were not observed in Caucasians or Asians (both P>0.05). Elevated DHEAS protein expression may be correlated with the biological pathophysiology of depression, indicating that checking DHEAS levels and administration of DHEAS could contribute to the effective treatment of depression.

    ABSTRACT: The aim of study was to evaluate the association between serum DHEAS levels and depression with a case-control study together with a meta-analysis. Radioimmunoassay (RIA) was performed to measure the serum DHEAS levels of all participants before and after treatment. Depression Patients were divided into mild depression and severe depression based on Hamilton depression scale (HAMD24) and received 5-hydroxytryptamine (5-HT) and citalopram (20mg/d) for 8 weeks. Case-control studies related to our study theme were enrolled for meta-analysis and Comprehensive Meta-analysis 2.0 (CMA 2.0) was used for statistical analysis. After treatment, DHEAS levels in depression patients were significantly increased, while before and after treatment, DHEAS levels were all lower in depression patients than in controls (all P<0.001); further analysis on age revealed that DHEAS levels were decreased with the rising of age. Meta-analysis results suggested that serum DHEAS levels (ng/mL) were significantly higher in healthy controls compared to depression patients (SMD=0.777, 95%CI=0.156-1.399, P=0.014). In conclusion, our study suggests that serum DHEAS levels are associated with the development of depression and it decreased with the rising of age. Copyright © 2015 Elsevier Ireland Ltd.
