Overview

Micro and nanoplastics (MNPLs) effects on human heath is still preliminary. Chronic kidney disease (CKD) participants, specially does patients submitted to hemodialysis, are a population high exposed to plastics. The objective of our research is to be able to detect MNPLs on biological fluids of hemodialysis patients as well as their potential genotoxic and immunological damage.

Description

The exponential increase in the production/use of plastic translates into a parallel increase of environmental plastic-waste that is continuously degraded into micro and nanoplastics (MNPLs). Information on the MNPLs' effects on human health is still preliminary and, furthermore, the limitations in current methodologies prevent accurate human exposure/risk assessment.

The study aims to analyse specific biomarkers of exposure to MNPLs in humans, as well as biomarkers of genetic damage, which will allow an association between exposure to these plastic materials and the optimisation of different techniques for the detection and characterisation of MNPLs.

The study will evaluate the effect of exposure to MNPLs, analysing the genotoxic damage, different biomarkers of exposure and the effects on microbiota, in different body samples (urine, blood and feces).

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
