Vliv denního příjmu erythritolu versus sacharózy po dobu 5 týdnů na glukózovou toleranci u dospívajících (EryAdo)

Vliv denního příjmu erythritolu versus sacharózy po dobu 5 týdnů na glukózovou toleranci u dospívajících: pilotní zkouška

This trial is divided into different parts: Part A the EryAdo trial and Part B the EryClot trial.

Part A EryAdo Trial:

Childhood and adolescence are crucial periods for prevention of obesity, as obese children are five times more likely to be obese at adulthood than lean children. To this purpose, sugar consumption should be reduced. The sugar alcohol erythritol is increasingly popular as sugar substitute in the food industry and is also recommended to diabetic patients. The substance is freely available. Recent acute studies show that erythritol has a positive influence on satiation and gastric emptying without affecting insulin and plasma glucose. In this trial, the investigators aim to assess the effect of a chronic intake of erythritol versus sucrose on insulin resistance in healthy adolescents.

Part B EryClot Trial:

In recently published studies, a prothrombotic effect of erythritol and xylitol was described.

Therefore, within a pilot study the investigators examined whether erythritol is detectable in the blood after administration of erythritol and conventional sweeteners (glucose and fructose). Also the effect on blood clotting was investigated.

These preliminary tests served to clarify the data situation so that further studies can be based on them.

The preliminary results of the pilot study indicated that there appears to be no measurable effect of erythritol on thrombocyte aggregation. This implicated that there is a discrepancy between our results and the results reported in a recent published study. This is why we need to assess the effects of erythritol in more detail (thrombocyte aggregation, and markers of platelet activation, endothelial activation and coagulation) in more subjects.

Due to a study published in 2024 describing similar prothrombotic effects for xylitol, this substance needs to be investigated as well. Thus, the participants will receive erythritol, xylitol, or water in a randomized order.

In addition to the EryClot ex vivo experiments, we will conduct in vitro experiments incubating platelet-rich plasma from healthy donors with increasing concentrations erythritol or xylitol followed by measurement of platelet aggregation by aggreegometry assay.

Detailní popis

Part A EryAdo Trial:

This trial aims to assess the effects of the daily intake of an erythritol-sweetened beverage over 5 weeks on insulin resistance, glucose tolerance and metabolism as well as on gut microbiota. Moreover, this study will also assess the effect of the above-mentioned intervention on food intake, body composition and gastrointestinal tolerance in this population.

Part B EryClot Trial:

The aim of this study is to investigate whether erythritol is detectable in the blood after administration of glucose and fructose, whether there is an effect of erythritol or xylitol on blood clotting and to investigate the platelet responsiveness in vitro in human plasma after addition of erythritol and xylitol.
