Abstract

Background

Schizophrenia is a debilitating psychiatric disorder with diverse cognitive impairments. Insulin-like growth factor binding protein 1 (IGFBP-1), a ubiquitous negative regulator of IGF signaling, crosses the blood–brain barrier after peripheral synthesis. Given the crucial role of IGF signaling in cognitive function, we reasoned that altered serum IGFBP-1 concentrations might be associated with cognitive impairments in schizophrenia. To test this hypothesis, we examined the relationship between serum IGFBP-1 levels and cognitive performance in both medicated and treatment-resistant schizophrenia (TRS) patients.

Methods

Serum IGFBP-1 was measured in 31 TRS patients, 49 chronic medicated schizophrenia (CMS) patients, and 53 healthy controls. Clinical symptom severity was evaluated using the Positive and Negative Syndrome Scale (PANSS) and cognitive functions using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).

Results

Both TRS and CMS patients exhibited cognitive deficits compared to healthy controls (p < 0.05). Serum IGFBP-1 concentration differed significantly among groups (F=36.805, p < 0.001) and post hoc tests demonstrated significantly higher concentrations in both schizophrenia groups compared to controls (p < 0.001). Further, serum IGFBP-1 concentration was higher in the TRS group than the CMS group (p = 0.048). Correlation analysis identified a significant relationship between serum IGFBP-1 and attention in the TRS group (r = 0.411, p = 0.021), immediate memory in the CMS group (r = -0.417, p = 0.003), and RBANS total score in the CMS group (r = -0.368, p = 0.009). Multiple regression analysis adjusting for confounding factors revealed that serum IGFBP-1 was independently associated with attention in TRS patients (p = 0.016, 95 %CI.

0.002–0.015) and immediate memory in CMS patients (p = 0.022, 95 %CI-0.012 to −0.001).

Conclusions

Elevated serum IGFBP-1 concentration may serve as a predictive biomarker for distinct cognitive deficits in TRS and CMS patients. Further investigations are warranted.

血清 IGFBP-1 水平升高与耐药和长期服药精神分裂症患者的认知缺陷有关。

背景精神分裂症是一种使人衰弱的精神疾病，伴有多种认知障碍。胰岛素样生长因子结合蛋白 1（IGFBP-1）是一种无处不在的 IGF 信号负调控因子，在外周合成后可穿过血脑屏障。鉴于 IGF 信号在认知功能中的关键作用，我们推断血清 IGFBP-1 浓度的改变可能与精神分裂症患者的认知障碍有关。为了验证这一假设，我们研究了服药和耐药精神分裂症（TRS）患者血清 IGFBP-1 水平与认知能力之间的关系：测量了 31 名 TRS 患者、49 名慢性药物治疗精神分裂症（CMS）患者和 53 名健康对照者的血清 IGFBP-1。采用阳性和阴性综合征量表（PANSS）评估临床症状的严重程度，采用神经心理状态评估可重复电池（RBANS）评估认知功能：结果：与健康对照组相比，TRS 和 CMS 患者均表现出认知功能缺陷（P＜0.05）：血清 IGFBP-1 浓度升高可作为 TRS 和 CMS 患者认知缺陷的预测性生物标志物。有必要进行进一步研究。

期刊介绍： The journal Cytokine has an open access mirror journal Cytokine: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. * Devoted exclusively to the study of the molecular biology, genetics, biochemistry, immunology, genome-wide association studies, pathobiology, diagnostic and clinical applications of all known interleukins, hematopoietic factors, growth factors, cytotoxins, interferons, new cytokines, and chemokines, Cytokine provides comprehensive coverage of cytokines and their mechanisms of actions, 12 times a year by publishing original high quality refereed scientific papers from prominent investigators in both the academic and industrial sectors. We will publish 3 major types of manuscripts: 1) Original manuscripts describing research results. 2) Basic and clinical reviews describing cytokine actions and regulation. 3) Short commentaries/perspectives on recently published aspects of cytokines, pathogenesis and clinical results.
