Palmitoylethanolamide/Luteolin Supplementation in Older Adults Undergoing Cardiac Surgery

2026년 6월 26일 업데이트: Fondazione IRCCS San Gerardo dei Tintori

Palmitoylethanolamide/Luteolin for the Maintenance of Cognitive Performance in Older Adults Undergoing Cardiac Surgery

Postoperative Cognitive Dysfunction (POCD) is a common complication after surgery, particularly among older adults. It is characterized by cognitive impairment, reduced functional independence, and decreased quality of life. Growing evidence suggests that neuroinflammation plays a relevant role in POCD development and persistence.

Palmitoylethanolamide (PEA) is an endogenous lipid mediator involved in the regulation of neuroinflammatory processes through the modulation of non-neuronal cells, while luteolin is a flavonoid with well-known antioxidant properties. Under conditions of prolonged neuroinflammation, endogenous PEA levels may be insufficient to adequately counteract pro-inflammatory signaling, making exogenous administration necessary.

In this context, exogenous micronized and ultramicronized PEA (mPEA and umPEA) supplementation has been shown to modulate cognitive and executive functions, working memory, language, and activities of daily living. Moreover, the combination of umPEA and luteolin (PEALut) may produce synergistic effects by modulating neuroinflammation and supporting neuronal function.

This study aims to evaluate whether postoperative administration of co-ultramicronized PEA and luteolin (700 mg + 70 mg in 10 mL), added to standard of care, may contribute to the mitigation of POCD in older adults undergoing elective cardiac surgery, compared to standard care alone.

결과 측정
측정값 설명
기간
Change in cognitive performance
기간: Baseline, hospital discharge (approximately postoperative day 7-10, depending on clinical course), 3 months after treatment, and 3 months after the end of treatment
Cognitive performance will be assessed using the Montreal Cognitive Assessment (MoCA), a 30-item screening tool that evaluates multiple cognitive domains, including memory, visuospatial ability, executive function, attention, language, and orientation. Scores range from 0 to 30, with higher scores indicating better cognitive performance.
Baseline, hospital discharge (approximately postoperative day 7-10, depending on clinical course), 3 months after treatment, and 3 months after the end of treatment

결과 측정
측정값 설명
기간
Incidence of Postoperative Cognitive Dysfunction (POCD)
기간: Hospital discharge (approximately postoperative day 7-10, depending on clinical course), and 3 months after treatment
Incidence of POCD will be defined as a decrease of at least 1 standard deviation from baseline MoCA score.
Hospital discharge (approximately postoperative day 7-10, depending on clinical course), and 3 months after treatment
Incidence, subtype and duration of postoperative delirium (POD)
기간: Daily, from 24 hours after the intervention until hospital discharge (approximately postoperative day 7-10, depending on clinical course)
Postoperative delirium will be assessed using the 4AT screening tool. A score of ≥4 suggests possible delirium (with or without cognitive impairment), with higher scores indicating greater severity of cognitive disturbance. Positive screenings will be confirmed using DSM-5 criteria. Delirium subtype will be classified using the Delirium Motor Subtyping Scale-4 (DMSS-4), and duration will be recorded in days from onset to resolution.
