Study 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.

Read the 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.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. significant change (mean±SD) in vitamin D status

    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

    Time frame: baseline and 8 weeks after intervention

Secondary outcomes

  1. significant change (mean±SD) in serum concentration of IL-1β and IL-6.

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

    Time frame: baseline and 8 weeks after intervention

  2. significant change (mean±SD) in serum concentration of hs-CRP

    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.

    Time frame: baseline and 8 weeks after intervention

  3. significant change (mean±SD) in serum concentration of bone biomarker

    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.

    Time frame: baseline and 8 weeks after intervention

  4. significant change (mean±SD) in platelet serotonin concentration (ng/10^9 platelets)

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

    Time frame: baseline and 8 weeks after intervention

  5. significant change (mean±SD) in serum concentration of oxytocin (µU/mL)

    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

    Time frame: baseline and 8 weeks after intervention

  6. significant change (mean±SD) in depression status

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

    Time frame: baseline and 8 weeks after intervention

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2018 (actual). Primary completion is estimated for Apr 2019, 11 months after the start.

Of 3,468 non-industry interventional studies with no phase under Depression, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 41. This study's planned 11 months is below that.

Counting every sponsor, half of 3,566 studies reached it within 21 months; a quarter within 9 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 13, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
