Serum VEGF Predicts Clinical Improvement Induced by Cerebrolysin Plus Donepezil in Patients With Advanced Alzheimer's Disease.

ABSTRACT: Serum vascular endothelial growth factor (VEGF) increases with Alzheimer's disease (AD) severity and may prevent cognitive decline. However, information on the influence of AD drug therapy on circulating VEGF is limited. This study assessed changes in serum VEGF levels and its association with clinical and functional responses in mild to moderate AD patients who were treated with Cerebrolysin, donepezil, or the combined therapy in a randomized, controlled trial. Treatment with Cerebrolysin plus donepezil reduced elevated serum VEGF levels and improved functioning and cognition significantly compared with donepezil alone in patients with advanced AD, and treatment differences were more pronounced in patients with higher VEGF levels. Our results indicate that the combined therapy reversed the increase of serum VEGF in advanced AD, which was associated with cognitive and functional responses, particularly in patients with high baseline VEGF.

Project description:BackgroundAlthough pemetrexed plus cis/carboplatin has become the most effective chemotherapy regimen for patients with advanced lung adenocarcinoma, predictive biomarkers are not yet available, and new tools to identify chemosensitive patients who would likely benefit from this treatment are desperately needed. In this study, we constructed and validated predictive peptide models using the serum peptidome profiles of two datasets.MethodsOne hundred eighty-three patients treated with first-line platinum-based pemetrexed treatment for advanced lung adenocarcinoma were retrospectively enrolled and randomized into the training (n = 92) or validation (n = 91) set, and pre-treatment serum samples were analyzed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and ClinProTools software. Serum peptidome profiles from the training set were used to identify potential predictive peptide biomarkers and construct a predictive peptide model for accurate group discrimination; which was then used to classify validation samples into "good" and "poor" outcome groups. The clinical outcomes of objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were analyzed based on the classification result.ResultsEight potential peptide biomarkers were identified. A predictive peptide model based on four distinct m/z features (2,142.12, 3,316.19, 4,281.94, and 6,624.02 Da) was developed based on the clinical outcomes of training set patients after first-line pemetrexed plus platinum treatment. In the validation set, the good group had significantly higher ORR (49.1% vs. 8.3%, P <0.001) and DCR (96.4% vs. 47.2%, P <0.001), and longer PFS (7.3 months vs. 2.7 months, P <0.001) vs. the poor group. However, the model did not predict OS (13.6 months vs. 12.7 months, P = 0.0675).ConclusionOur predictive peptide model could predict pemetrexed plus platinum treatment outcomes in patients with advanced lung adenocarcinoma and might thus facilitate appropriate patient selection. Further studies are needed to confirm these findings.
