Plant Stanol Esters and COVID-19 Vaccination Response
11 de febrero de 2022 actualizado por: Maastricht University Medical Center
The Effect of Plant Stanol Ester Consumption on the Vaccination Response to a COVID-19 Vaccine
Plant stanols are known to lower low-density lipoprotein cholesterol (LDL-C).
However, studies have suggested that these compounds also beneficially influence the immune system, e.g.
increasing vaccine-specific antibody titers.
BMI has previously been negatively associated to vaccination responses.
If plant stanols indeed have beneficial effect on the immune system, people with overweight or obesity might benefit from consuming plant stanols prior to receiving the COVID-19 vaccination.
The primary objective of this study is to demonstrate clinical benefits of consumption of plant stanols (delivered via products enriched with plant stanol esters) on the vaccination response to a COVID-19 vaccine in overweight or obese patients.
The main study endpoint is vaccination response to a COVID-19 vaccine.
Secondary endpoints include amongst others hematological, inflammatory and immunological parameters (e.g.
hs-CRP, leukocyte differential count) and metabolic markers (e.g.
blood lipid profiles, plasma glucose, serum insulin, HOMA-IR).

Armas e Intervenciones
Grupo de participantes/brazo |
Intervención / Tratamiento |
|---|---|
|
Experimental: Plant stanol group
This arm receives 4g of plant stanols per day (delivered as plant stanol esters) by consuming mini drinks (100 mL each).
|
Oat milk based mini drinks (100 mL) containing 2g plant stanols each (delivered as plant stanol esters).
First dose of one of the COVID-19 vaccines.
Participants have to wait until they are invited to receive the vaccine by the government; this study does not interfere with national planning of the vaccines.

|
Comparador de placebos: Placebo group
This arm receives mini drinks without added plant stanols (delivered as plant stanol esters).

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Vaccine specific antibody titers
Periodo de tiempo: Change T=0 and T= 4 weeks
|
The response to the COVID-19 vaccine will be measured by quantifying specific antibody titers (vaccine specific IgG and IgM).
These titers will be measured in blood samples collected weekly during the month after vaccination by suitable ELISAs.
