Not Applicable
Conditions
Depression
Interventions
Dietary Supplement: Placebo
Dietary Supplement: vitamin D supplement
Registration Number
NCT03766074
Lead Sponsor
Tirang R. Neyestani, Ph.D.
Brief Summary

Groups (intervention group receives 50000 IU vitamin D and control group receives placebo) through a random allocation. After 8 weeks, blood sample will be collected from each participant. The studied indices (inflammatory (IL-1β, IL-6, hs-CRP), PTH, platelet serotonin, serum oxytocin, serum 25(OH) D, depression status and anthropometry indices) will be evaluated at beginning and end of interventional period.

Detailed Description

In this double-blind randomized clinical trial, 60 patients aged 18-60y referred to Baharlou hospital with a history of mild to moderate depression diagnosed by a psychiatrist will be presented to the researcher. After receipt of a signed informed consent form, eligible patients will participate. A general demographic questionnaire will be completed by an interviewer. Individuals are randomly divided into intervention and control groups. A 10-ml venous blood sample will be collected from each participant. The intervention group receives 50000 IU of vitamin D every 2 weeks as vitamin D supplements for 8 weeks, provided monthly. The control group receives placebo. The drug schedule of both groups (if any) will be unchanged according to the prescribing physician. After 8 weeks, blood sample will be collected from each participant. The studied indices (inflammatory (IL-1β, IL-6, hs-CRP), PTH, platelet serotonin, serum oxytocin, serum 25(OH) D, depression status, anthropometry indices) will be evaluated at beginning and end of interventional period. Data will be analyzed by statistical tests.

Primary Outcome Measures
NameTimeMethod
significant change (mean±SD) in vitamin D statusbaseline and 8 weeks after intervention

The serum concentration of 25(OH) D (nmol/L) will be measured at baseline and 8 weeks after intervention. normal range is 25-162 nmol/L

Secondary Outcome Measures
NameTimeMethod
significant change (mean±SD) in serum concentration of hs-CRPbaseline and 8 weeks after intervention

The serum concentration of hs-CRP (mg/L) will be measured at baseline and 8 weeks after intervention. normal range is 0.3-8.6 mg/L.

significant change (mean±SD) in platelet serotonin concentration (ng/10^9 platelets)baseline and 8 weeks after intervention

The platelet serotonin concentrations (ng/10\^9 platelets) will be measured at baseline and 8 weeks after intervention. normal range is 154-1086.

significant change (mean±SD) in serum concentration of oxytocin (µU/mL)baseline and 8 weeks after intervention

The serum concentrations of oxytocin (µU/mL) will be measured at baseline and 8 weeks after intervention. normal range is : males:1.1-1.9, females (non-pregnant): 1.0-1.8

significant change (mean±SD) in serum concentration of IL-1β and IL-6.baseline and 8 weeks after intervention

The serum concentration of IL-1β and IL-6 (pg/mL) will be measured at baseline and 8 weeks after intervention.

significant change (mean±SD) in serum concentration of bone biomarkerbaseline and 8 weeks after intervention

The serum concentration of parathormone (PTH) (pg/mL) will be measured at baseline and 8 weeks after intervention. normal range is 10-65 pg/mL.

significant change (mean±SD) in depression statusbaseline and 8 weeks after intervention

Depression status will be measured by using Beck questioner at baseline and 8 weeks after intervention.
