Unveiling hidden contaminants: a systematic quantification and characterization of microplastics in hemodialysis and peritoneal dialysis fluids
AI summary Read the abstract
Researchers systematically analyzed hemodialysis and peritoneal dialysis fluids for microplastic contamination and found plastic particles, predominantly fibers, in all tested samples. The microplastics were identified using advanced spectroscopic techniques and included polymers like polyethylene and polypropylene. The findings raise concerns about chronic microplastic exposure in dialysis patients, who are exposed to large volumes of these fluids over time.
Microplastics (MPs) are an emerging environmental and biomedical concern due to their potential bioaccumulation and toxic effects. Given the extensive exposure of dialysis patients to large volumes of dialysate and water, the presence of MPs in dialysis solutions raises concerns regarding chronic exposure and systemic implications. This study systematically quantifies and characterizes MPs in hemodialysis (HD) and peritoneal dialysis (PD) fluids, investigating their sources and potential health risks. A total of 30 dialysis solution samples were analysed (revealing 36 suspect particles) using advanced spectroscopic techniques, including Fourier-transform infrared (FT-IR) spectroscopy, to identify polymer compositions. MPs predominantly fibers, were detected in all tested solutions, with polyethylene (PE), polyvinyl chloride (PVC), and ethylene-vinyl acetate (EVA) as the primary polymers. Statistical analyses confirmed significant variability in MP contamination across different dialysis fluids. Hemodialysis and peritoneal dialysis solutions show no statistically significant difference in MP concentration (HD: 0.29 ± 0.16 mp.L⁻¹, PD: 0.34 ± 0.02 mp.L⁻¹, p = 0.86). MP particles in HD solutions (1.31 ± 0.98 mm) are significantly larger than those in PD solutions (0.64 ± 0.43 mm) (p = 0.030). Despite similar MP concentrations, PD patients are estimated to be exposed to ~ 50% more MPs weekly than HD patients (9.57 ± 5.28 vs. 14.28 ± 0.84 mp. L⁻¹, p < 0.001). These findings highlight a potential, yet underrecognized, source of MP exposure in dialysis patients, necessitating further investigation into the implications of chronic MP absorption on renal function and systemic health. Regulatory policies should prioritize improved filtration techniques, alternative polymer-free materials, and stricter quality control measures to mitigate MP contamination in medical solutions. Future research should explore the long-term effects of MP exposure in dialysis-dependent individuals and refine analytical methodologies for contamination assessment.

Microplastics and nanoplastics in haemodialysis waters: Emerging threats to be in our radar
AI summary Read the abstract
This study investigated whether kidney dialysis patients are being exposed to micro and nanoplastics during their treatments, since they process 300 to 600 liters of water per week. The researchers found several potential contamination points in the dialysis process and estimated that even with 99% filtration, plastic particles could still reach patients' kidneys. This is especially concerning because dialysis patients already have compromised kidney function and may be more vulnerable to plastic particle exposure.

Microplastic Accumulation in Arteriovenous Fistulas (AVF) of Dialysis Patients
AI summary Read the abstract
Researchers found tiny plastic particles, called microplastics, built up in the blood vessel access points used for dialysis in kidney patients. This suggests microplastics from our environment can accumulate inside the human body, raising questions about whether they might affect blood vessel health, especially in people who rely on medical devices like dialysis access ports.
The landscape of micron-scale particles including microplastics in human enclosed body fluids
AI summary Read the abstract
Researchers conducted the first comprehensive survey of micron-scale particles, including microplastics, across thirteen types of human body fluids spanning eight organ systems. They detected microparticles in multiple enclosed body fluids, with polyethylene and polyamide among the most common plastic types found. The findings suggest that microplastic exposure in humans is more widespread than previously understood, with particles reaching diverse internal compartments.
