Abstract

Background Neuroplastic processes are thought to be involved in the pathophysiology of major depression. It has been reported that serum brain-derived neurotrophic factor (BDNF) is decreased in depressed patients. Objectives Compare BDNF levels in depressed patients and healthy controls in platelet poor plasma and in washed platelets. Observe the effects of 8- and 24-week treatment with S-citalopram on these levels. Methods We assessed the levels of BDNF in platelet poor plasma and in washed platelets from 18 major depression patients, and compared them with 14 healthy controls. Blood samples were obtained from patients before and during treatment (8 and 24 weeks) with a selective serotonin reuptake inhibitor, S-citalopram. Results A significant decrease in severity of depressive symptoms was observed from the first month of treatment with S-citalopram, and symptoms continued decreasing until the 6th month. Plasma BDNF levels in untreated patients appeared significantly increased (p<0.01) but reached values similar to those of controls at the 24th week. In contrast, levels of platelet BDNF appeared significantly decreased (p<0.05), but treatment also normalized levels so that values obtained were equivalent to those of controls. Conclusions Untreated depressed patients showed increased plasma BDNF levels and decreased platelet BDNF levels, as compared with control subjects, and tend to normalize during treatment with S-citalopram for 24 weeks, with BDNF reaching levels similar to those in healthy controls at the 24th week in both samples. We observed that improvement in depressive symptoms was accompanied by normalization of plasma and platelet BDNF levels.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
