To compare the serum levels of brain-derived neurotrophic factor (BDNF) in type 2 diabetes mellitus (T2DM) patients with healthy controls (HC) and evaluate the BDNF levels in T2DM patients with/without cognitive impairment.
PubMed, EMBASE, and the Cochrane Library databases were searched for the published English literature on BDNF in T2DM patients from inception to December 2022. The BDNF data in the T2DM and HC groups were extracted, and the study quality was evaluated using the Agency for Healthcare Research and Quality. A meta-analysis of the pooled data was conducted using Review Manager 5.3 and Stata 12.0 software.
A total of 18 English articles fulfilled with inclusion criteria. The standard mean difference of the serum BDNF level was significantly lower in T2DM than that in the HC group (SMD: -2.04, z = 11.19, P <0.001). Besides, T2DM cognitive impairment group had a slightly lower serum BDNF level compared to the non-cognitive impairment group (SMD: -2.59, z = 1.87, P = 0.06).
BDNF might be involved in the neuropathophysiology of cerebral damage in T2DM, especially cognitive impairment in T2DM.
比较 2 型糖尿病(T2DM)患者与健康对照者(HC)的血清脑源性神经营养因子(BDNF)水平,并评估 T2DM 患者中有无认知障碍时的 BDNF 水平。
检索 PubMed、EMBASE 和 Cochrane 图书馆数据库中自成立至 2022 年 12 月发表的关于 T2DM 患者 BDNF 的英文文献。提取 T2DM 组和 HC 组的 BDNF 数据,并使用美国医疗保健研究与质量局评估研究质量。使用 Review Manager 5.3 和 Stata 12.0 软件对汇总数据进行荟萃分析。
共纳入 18 篇符合纳入标准的英文文献。T2DM 患者的血清 BDNF 水平的标准均数差明显低于 HC 组(SMD:-2.04,z=11.19,P<0.001)。此外,与非认知障碍组相比,T2DM 认知障碍组的血清 BDNF 水平略低(SMD:-2.59,z=1.87,P=0.06)。
BDNF 可能参与了 T2DM 患者脑损伤的神经病理生理学过程,尤其是 T2DM 的认知障碍。
