Therapeutic plasma exchange reduced circulating microplastics by approximately 60% in patients with elevated particle burden, according to a clinical study of over 100 patients published in the Journal of Clinical Apheresis. This represents the first clinical evidence that a mechanical intervention can remove microplastics from human circulation.
Key Points
- Plasma exchange reduced mean microplastics from 52.2 to 21.1 particles per 100 µL
- First clinical evidence of microplastic removal via medical intervention
- Study included 100+ patients with validated quantification methodology
Longevity Analysis
Microplastic accumulation represents an emerging detoxification burden with unknown long-term consequences for tissue integrity and systemic function. The ability to quantify and mechanically remove microplastics from circulation opens a pathway for understanding whether microplastic load contributes to accelerated aging across multiple organ systems. This work shifts microplastics from a passive exposure problem to an addressable physiological parameter, provided the intervention proves durable and scalable. Whether plasma exchange improves downstream health outcomes—particularly in organs known to accumulate particles—remains to be established.
