[Predictive value of inflammatory indicators for post-stroke depression in patients with ischemic stroke].

Abstract

OBJECTIVE:

To investigate the association of venous blood neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) and levels of interleukin-17 (IL-17) and IL-6 at 2 weeks after admission with the occurrence of post-stroke depression (PSD) in patients with first-ever acute ischemic stroke.

METHODS:

The hospitalized patients with first-ever acute ischemic stroke were recruited consecutively from the Department of Neurology of Yijishan Hospital from March, 2015 to September, 2017. The demographic and baseline clinical data on admission and the imaging data were collected. The diagnosis of PSD was established in line with DSM-IV (SCID-I-R) at 3 months during the follow-up. The severity of PSD was assessed using the Hamilton Depression Scale (HAMD-17). Multivariate logistic regression analysis was used to investigate the correlation of NLR, PLR, IL-17, and IL-6 with PSD in these patients.

RESULTS:

A total of 376 patients with acute ischemic stroke were enrolled, including 224 male patients (59.57%) and 152 female patients (40.43%), whose mean age was 61.37±10.34 years. Of these patients 104 (27.66%) were found to have PSD. Univariate analysis showed that gender, years of education, BMI, widowhood, NIHSS score, MMSE score, mRS score, and laboratory indexes (NLR, PLR, IL-17, and IL-6) were all significantly correlated with PSD (all P < 0.05). Multivariate logistic regression analysis showed that, after adjusting for the compounding factors, the third quartile of NLR (P < 0.001), the third quartile of PLR (P=0.002), IL-17 (P=0.025) and IL-6 (P=0.016) were independent factors that predicted the occurrence of PSD.

CONCLUSIONS:

Elevated NLR and PLR at admission and levels of IL-17 and IL-6 at 2 weeks after admission are all independent predictors of the occurrence of PSD at 3 months after stroke.
