Abstract:
Objective To investigate the effects of serum levels of leptin, IGF-1, BDNF and inflammatory markers in patients with post-stroke depression(PSD). Methods By using Hamilton rating scale for depression (HAMD) ,46 patients with post-stroke depression were recruited and 50 patients without depression as the control group. Two weeks after the onset of stroke, serum levels of leptin, insulin growth factor(IGF-1), hs-CRP, intracellular adhesion molecule (ICAM-1) and brain-derived neurotrophic factors (BDNF) were measured by enzymelinked immunosorbent assay(ELISA). Results The levels of leptin and IGF-1 in patients with PSD were significantly higher than that of the control group (( 57.4 ± 14.32) ng/ml vs (17.53 ± 11.62) ng/ml, P = 0. 002;(120.86 ±28.66) ng/ml vs (66.5 ± 17.51) ng/ml, P=0. 004 respectively). The serum levels of leptin and IGFI were positively correlated with the HAMD score(r=0. 724, P＜0. 01; r=0. 641, P＜0. 01 respectively). There was no significant differences in the levels of hs-CRP((2.3 ±0.42) mg/dl vs (2.2 ± 0.28) mg/dl, P= 0. 767),ICAM-1 (( 182.6 ± 50.27) ng/ml vs (178.7 ± 51.14) ng/ml, P = 0. 812) and BDNF(( 25.8 ± 8.35) ng/ml vs (24.2 ±7.48)ng/ml, P = 0.580)in the two groups. Conclusion The serum levels of leptin and IGF-1 may be associated with post-stroke depression and may be the markers of PSD in the old stroke patients.
