Association between IL-17, IL-23 with neurocognitive scales in patients with Alzheimer’s disease

| Summary: | Introduction
Alzheimer’s disease (AD) is a degenerative brain disease and the most common cause of dementia. Evidence suggests that various cytokines, including interleukins (IL) IL-6, IL-10, IL-12 are actively involved in the pathogenesis of AD. The role of IL-17 and IL-23 is less clear.
Objectives
To investigate the correlations between IL-17, IL-23, and neurocognitive scales in patients with Alzheimer’s disease.
Methods
The study included 45 patients: 15 patients with Alzheimer’s disease and 30 patients without cognitive deficit (control group). Clinical and psychometrical methods were used: Mini Mental State Examination (MMSE) scale; Montreal Cognitive Assessment (MoCA), Frontal Assessment Battery (FAB), Alzheimer Disease Assessment Scale-cognitive (ADAS ̶ cog). Serum levels of cytokines of IL-17 and IL-23 were analyzed by sandwich ELISA on “Chem Well 2900” immunoanalyzer (Awareness Technology, USA).
Results
A significantly positive correlation was observed between IL-17 and IL-23 for all AD patients (r =0.723, p=0.002). A significant inverse correlation was observed between serum concentration of IL-17 and MoCA score (r=˗1.0, р≤.0001) and IL-23 and MMSE score (r=˗0.553, р=0.032) in all AD patients. However, no other significant correlations were found between IL-17 and the scores MMSE, FAB, ADAS ̶ cog and between IL-23 and the scores MoCA, FAB and ADAS ̶ cog.
Conclusions
Proinflammatory cytokines (such as IL-17 and IL-23) have been associated with cognitive impairment. However, the complicated relationships of the two cytokines with the pathogenesis of AD need to be further investigated in the future.
Disclosure
No significant relationships.
