Background: The inflammation and oxidative stress are thought to play an important role in the etiopathogenesis of some psychological disorders. We aimed to assess the potential relationships between serum fat soluble vitamins (Vitamins A and E), antibody titers to Hsp27 (anti-Hsp27) and hematological markers of inflammation, with mood disorders in a population of adolescent girls., Methods: A total of 563 adolescent girls (Age 12-18 years) were included in the study. The presence and severity of depression, insomnia and sleepiness were assessed using validated questionnaires. Serum vitamins A and E, anti-Hsp27 antibody titers, white blood cell, lymphocyte, neutrophil, platelet counts, and red blood cell distribution width (RDW), were also measured. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and RDW to platelet ratio (RPR) were calculated., Results: Serum anti-HSP27 antibody titers, PLR, and RPR values was significantly higher in subjects with a high depression score compared to normal individuals (p < 0.05). However, there was no association between serum inflammatory markers concentrations and sleep disorders; although individuals with insomnia had a lower vitamin E/HDL ratio compared to healthy adolescents. In multivariate logistic regression analyses adjusted for potential confounders, anti-HSP was an independent predictor of severe depression (OR = 5.0, 95% CI: 1.6-15.7, p < 0.05)., Limitation: The cross-sectional design of study and the inclusion of only female adolescents participants are limitations., Conclusion: Our findings suggest that serum anti-HSP27 antibody titers may be useful biological marker in depressive patients. This finding may support a role of oxidative stress in the etiology of depression, and targeting this pathway may be of value in the treatment of depression., (Copyright © 2019 Elsevier B.V.

Although vitamin D deficiency is known to be a risk factor for some psychological disorders, there have been few studies on the effects of vitamin D supplementation on their symptoms. Depression and aggression are common mental disorders and are associated with disability and disease burden. We aimed to evaluate the effectiveness of high-dose vitamin D supplementation on depression and aggression scores in adolescent girls. Nine hundred forty adolescent girls received vitamin D 3 at a dose of 50,000 IU/week for 9 weeks. Anthropometric parameters and blood pressure were measured using standard protocols at the baseline and at the end of the study. Depression score was evaluated using the Beck Depression Inventory-II and aggression was evaluated using the Buss-Perry Aggression Questionnaire at baseline and at the end of the study. Comparison among the four categories of depression score (normal, mild, moderate, and severe) revealed no significant differences in demographic and anthropometric parameters at baseline. After 9 weeks of vitamin D supplementation, there was a significant reduction on mild, moderate, and severe depression score. However, vitamin D supplementation had no significant effect on aggression score. Our results suggest that supplementation with vitamin D may improve depressive symptoms among adolescent girls, as assessed by questionnaire, but not aggression score. Formal, larger, randomized controlled studies are required to confirm this effect on cases with different degrees of depression.

Objective: Hormonal variations during the menstrual cycle may affect emotional regulation. We aimed to investigate the association between dysmenorrhea (the severe abdominal pain and cramps associated with menstruation) and cognitive abilities, emotional function and sleep patterns in adolescent girls. Moreover, we evaluated the frequency of premenstrual syndrome (PMS) in our population and then divided them into 4 groups: subjects with only PMS; subjects with only dysmenorrhea; individuals with both PMS and dysmenorrhea and normal subjects., Study Design: In this cross sectional study, 897 adolescent girls who had entered menarche were recruited. Of these, 35.9% had only dysmenorrhea, 14.9% had only PMS, 32.7% had both PMS and dysmenorrhea while 16.5% had no PMS and/or dysmenorrhea (Normal). We assessed the tests for cognitive, emotional function and sleep patterns were compared for these groups., Results: Individuals in the dysmenorrhea group had significantly higher depression, aggression, insomnia, daytime sleepiness and sleep apnea scores compared to normal controls and the PMS group, but did not have significantly different cognitive ability (P value <0.05). These differences were strongly correlated to pain intensity (P<0.001). However, there were no significant differences between those with only PMS and control subjects with regard to cognitive ability, emotional function and sleep pattern tests., Conclusions: Dysmenorrhea is highly prevalent among adolescents and appears to be associated with depressive mood, a tendency to aggressive behavior and sleep disorders among adolescent girls., (Copyright © 2017 Elsevier B.V.
