Microplastics increase the hepato-pathophysiological complications and decrease the therapeutic efficacy of Metformin in T2-DM rats

AI summary Read the abstract

In diabetic rats, exposure to microplastics worsened liver damage and actually made the diabetes drug metformin less effective at controlling blood sugar and protecting the liver. This matters because it suggests that everyday plastic contamination could quietly undermine treatment for the millions of people managing type 2 diabetes, though more research is needed to confirm this happens in humans.

Background: The widespread usage of plastic materials in the majority of daily activities has made microplastics (MPs) contamination a global issue. Aim of the work: This study addressed how long-term MPs administration affected the hepato-pathophysiological changes in type 2 diabetes mellitus (T2-DM) rats. Materials and Methods: Forty Sprague Dawley rats were separated into; group 1 (Gp1) serving as a negative control. Rats from Gp2 to Gp4 were maintained on a high-fat diet (HFD) for twelve weeks. Subsequently injected with streptozotocin (30 mg/kg b.wt.) intraperitoneally (i.p.). As a single dose, 150 mg/kg b.wt of metformin (Met) was administered orally to Gp3. A dose of 50 mg/kg b.wt of MPs was provided orally to Gp4. Gp5 received Met, and MPs. Treatments with Met or Met/MPs were carried out for eight weeks, daily. The percentages of changes in rats' body weight were examined, as well as the hematological, biochemical, histological, and immunohistochemical analyses were confirmed. Results: Met therapy improved the hepato-pathophysiological changes in T2-DM rats. Hepato-pathophysiological alterations increased upon MPs were administered to T2-DM rats. Furthermore, administering MPs along with Met decreased the effectiveness of its treatment. These findings were further confirmed by histological and immunohistochemical examinations that revealed by disorganization of the hepatic architecture, vacuolated hepatocytes, some with pyknotic nuclei and highly significance of caspase 3 immunoreaction expression specially in liver tissues of MPs administered group Conclusion: This study showed that MPs increased the hepato-pathophysiological changes in T2-DM rats and decreased Met effectiveness. The mechanisms underlying these effects need to be further investigated.

Gut barrier breach and glucose dysregulation: the dual threat of food-transformed microplastics

AI summary Read the abstract

Scientists found that when microplastics from plastic water bottles mix with food (especially starchy foods) during digestion, they get chemically altered in ways that make them more harmful to your gut. In lab tests, these food-transformed microplastics damaged the protective lining of the intestines and appeared to increase glucose absorption, meaning they could potentially affect blood sugar levels beyond just causing gut irritation. This suggests that what you eat alongside microplastic-contaminated food and water may influence how much damage those plastics actually cause in your body.

Microplastics, nanoplastics and liver disease: an emerging health concern?

AI summary Read the abstract

Researchers reviewed emerging evidence that microplastics and nanoplastics accumulate in human liver tissue at increasing concentrations over the past decade, trigger oxidative stress, fibrogenesis, and inflammation in cell and animal models, and may carry microbial pathogens and endocrine-disrupting chemicals, introducing the concept of plastic-induced liver injury as a new focus for environmental hepatology.
