[PMID: 36231509 PMCID: PMC9566616 DOI: 10.3390/ijerph191912209] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/20/2022] [Accepted: 09/23/2022] [Indexed: 05/15/2023]
Abstract
Chlorpyrifos (CPF) was the most frequently used pesticide in food production in the European Union (EU) until 2020. Unfortunately, this compound is still being applied in other parts of the world. National monitoring of pesticides conducted in various countries indicates the presence of CPF in soil, food, and water, which may have toxic effects on consumers, farmers, and animal health. In addition, CPF may influence changes in the population of fungi, bacteria, and actinomycete in soil and can inhibit nitrogen mineralization. The mechanisms of CPF activity are based on the inhibition of acetylcholinesterase (AChE) activity. This compound also exhibits reproductive toxicity, neurotoxicity, and genotoxicity. The problem seems to be the discrepancy between the actual observations and the final conclusions drawn for the substance's approval in reports presenting the toxic impact of CPF on human health. Therefore, this influence is still a current and important issue that requires continuous monitoring despite its withdrawal from the market in the EU. This review traces the scientific reports describing the effects of CPF resulting in changes occurring in both the environment and at the cellular and tissue level in humans and animals. It also provides an insight into the hazards and risks to human health in food consumer products in which CPF has been detected.

Abstract
BACKGROUND Disruption of the gut microbiota homeostasis may induce low-grade inflammation leading to obesity-associated diseases. A major protective mechanism is to use the multi-layered mucus structures to keep a safe distance between gut epithelial cells and microbiota. To investigate whether pesticides would induce insulin resistance/obesity through interfering with mucus-bacterial interactions, we conducted a study to determine how long-term exposure to chlorpyrifos affected C57Bl/6 and CD-1 (ICR) mice fed high- or normal-fat diets. To further investigate the effects of chlorpyrifos-altered microbiota, antibiotic treatment and microbiota transplantation experiments were conducted. RESULTS The results showed that chlorpyrifos caused broken integrity of the gut barrier, leading to increased lipopolysaccharide entry into the body and finally low-grade inflammation, while genetic background and diet pattern have limited influence on the chlorpyrifos-induced results. Moreover, the mice given chlorpyrifos-altered microbiota had gained more fat and lower insulin sensitivity. CONCLUSIONS Our results suggest that widespread use of pesticides may contribute to the worldwide epidemic of inflammation-related diseases.

Abstract
BACKGROUND Higher efficacy of incretin-based therapies for type 2 diabetes mellitus has been reported from Asia. Pancreatitis and hepatitis have also been suspected to occur due to dipeptidyl peptidase-4 inhibitor (DPP4I) treatment. The present study aims at comparing selected biochemical parameters among DPP4 inhibitor users and other oral hypoglycaemic drug users. METHODS Patients were recruited from the State Pharmaceutical Corporation, Anuradhapura, Sri Lanka, for a comparative cross-sectional study. Two groups were involved: "DPP4I" user group (n = 63) and "other oral hypoglycaemic" user group (n = 126). Mann-Whitney U test was performed to find a significant difference (p < 0.05) in the distributions of HbA1C, pancreatic amylase, serum lipase, AST and ALT levels between the two groups. RESULTS Contradicting to previous Asian studies, distribution of HbA1C (p = 0.569) between anti-diabetic regimes with and without DPP4 inhibitors showed no significant difference. Also, amylase (p = 0.171), AST (p = 0.238) and ALT (p = 0.347) failed to show significance. However, lipase was significantly (p = 0.012) high in the DPP4I group. CONCLUSION The study showed a significantly higher lipase level among the DPP4I users in comparison to other oral hypoglycaemic drug users, and possible reasons were discussed.

Abstract
Higher incidence of diabetes along with increased use of pesticides is seen in Southeast Asia. Recent hypothesis postulated a link between acetylcholinesterase inhibitor insecticides and type 2 diabetes through the GLP-1 pathway. This study compares the GLP-1 response between groups with low and high red blood cell acetylcholinesterase (RBC-AChE) activity. A comparative cross-sectional study was conducted amongst patients who were within 3 months after an acute organophosphate or carbamate poisoning (acute group) and amongst vegetable farmers with low (chronic group) and high (control group) RBC-AChE activity. Acute (366 mU/μM Hb) and chronic (361 mU/μM Hb) groups had significantly lower RBC-AChE activity in comparison to the control (471 mU/μM Hb) group (P < 0.0001). Only the acute group, which has had atropine therapy, showed a significantly lower 120 min value in comparison to the control group (P = 0.0028). Also, the acute group had significantly low late (P = 0.0287) and total (P = 0.0358) responses of GLP-1 in comparison to the control group. The findings of the study allude towards attenuation of GLP-1 response amongst patients after acute organophosphate and carbamate poisoning. The possibility of an atropine-mediated attenuation of GLP-1 response was discussed.

Abstract
Type 2 diabetes has rapidly developed into a major public health problem in south Asia (defined here as Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka) in recent decades. During this period, major lifestyle changes associated with economic transition, industrialisation, urbanisation, and globalisation have been key determinants in the increasing burden of non-communicable diseases. A decline in nutrition quality, reduced physical activity, and increased sedentary behaviours are reflected in the increasing prevalence of type 2 diabetes and related risk factors in the region. The International Diabetes Federation 2017 estimates of the prevalence of diabetes in adults in the region range from 4·0% in Nepal to 8·8% in India. The prevalence of overweight ranges from 16·7% in Nepal to 26·1% in Sri Lanka, and the prevalence of obesity ranges from 2·9% in Nepal to 6·8% in Sri Lanka. An increasing proportion of children, adolescents, and women are overweight or obese, leading to a heightened risk of type 2 diabetes. Ethnic south Asians present with greater metabolic risk at lower levels of BMI compared with other ethnic groups (referred to as the south Asian phenotype), with type 2 diabetes often developing at a younger age, and with rapid progression of diabetic complications. Because of the presence of multiple risk factors and a body composition conducive to the development of type 2 diabetes, south Asians should be aggressively targeted for prevention. In this Series paper, we detail trends in the prevalence of diabetes in the region and address major determinants of the disease in the context of nutrition and physical activity transitions and the south Asian phenotype.

Short-term glucose dysregulation following acute poisoning with organophosphorus insecticides but not herbicides, carbamate or pyrethroid insecticides in South Asia. Clin Toxicol (Phila) 2018; 57:254-264.

Abstract
BACKGROUND Ingestion of organophosphorus (OP) insecticides is associated with acute hyperglycaemia. We conducted a prospective study to determine whether glucose dysregulation on admission associated with ingestion of OP insecticides or other pesticides is sustained to hospital discharge or to 3-12 months later. METHODS We recruited participants to two similar studies performed in parallel in Anuradhapura, Sri Lanka, and Chittagong, Bangladesh, following hospitalisation for OP insecticide, herbicide or other pesticide self-poisoning. Two-hour 75 g oral glucose tolerance testing (OGTT) was performed after recovery from the acute poisoning, at around the time of discharge. In Sri Lanka, a four time-point OGTT for area-under-the-curve (AUC), C-peptide and homeostatic modelling of insulin resistance (HOMA-IR) was undertaken, repeated after 1 year. In Bangladesh, a 2-h OGTT for glucose was undertaken and repeated after 3 months in participants with initial elevated 2-h glucose. We compared glucose homeostasis by poison group and adjusted findings for age, BMI and sex. FINDINGS Seventy-three Sri Lankan and 151 Bangladeshi participants were recruited. We observed higher mean [SD] fasting (4.91 [0.74] vs. 4.66 [0.46] mmol/L, p = .003) and 2-h glucose (7.94 [2.54] vs. 6.71 [1.90] mmol/L, p < .0001) in OP-poisoned groups than pyrethroid, carbamate, herbicide or 'other poison' groups at discharge from hospital. In Sri Lanka, HOMA-IR, glucose and C-peptide AUC were higher in OP than carbamate or herbicide groups. Adjusted analyses remained significant except for fasting glucose. Follow-up analysis included 92 participants. There was no significant difference in OGTT results between OP-poisoned and other participants at follow-up (mean [SD] 2-h fasting glucose 4.67 [0.92] vs. 4.82 [0.62], p = .352; 2-h glucose 6.96 [2.31] mmol/L vs. 6.27 [1.86] mmol/L, p = .225). CONCLUSION We found in this small prospective study that acute OP insecticide poisoning caused acute glucose dysregulation that was sustained to hospital discharge but had recovered by 3-12 months. Acute glucose dysregulation was related to defects in insulin action and secretion. This study did not address long-term risk of diabetes following acute OP insecticide poisoning, but could provide the data for a power calculation for such a study.

Abstract
Glucagon like peptide 1 (GLP1) is an incretin hormone released from the enteroendocrine L-type cells of the lower gastrointestinal tract. The active isoforms of GLP1 are rapidly degraded (<2 min) by protease dipeptidyl peptidase-4 (DPP-4) after their release. Among its functions, GLP1 exerts a pivotal role in regulating glucose and lipid metabolism. In particular, GLP1 increases glucose stimulated insulin secretion, functional pancreatic β-cell mass and decreases glucagon secretion from pancreatic α-cells. GLP1 can also be a regulator of lipid and lipoprotein metabolism ameliorating diabetic dyslipidemia, liver steatosis, and promoting satiety. Interestingly, it has been found that GLP1 and GLP1 agonists can modulate the expression of different microRNAs (miRNAs), a ~22 nucleotides small non-coding RNAs, key modulators of protein expression. In particular, in pancreas, GLP1 increases the expression levels of miRNA-212 and miRNA-132, stimulating insulin secretion. Similarly, GLP1 decreases miRNA-338 levels, leading to an increase of pancreatic β-cell function, followed by an improvement of diabetic conditions. Moreover, GLP1 modulation of miRNAs expression in the liver regulates hepatic lipid storage. Indeed, GLP1 down-regulates miRNA-34a and miRNA-21 and up-regulates miRNA-200b and miRNA-200c expression in liver, reducing intra hepatic lipid accumulation and liver steatosis. Clinical and pre-clinical studies, discussed in this review, suggest that modulation of GLP1/miRNAs pathway may be a useful and innovative therapeutic strategy for prevention and treatment of metabolic disorders, such as diabetes mellitus and liver steatosis.

Abstract
Bisphenol A (BPA) can disrupt glucose homeostasis and impair pancreatic islet function; however, the mechanisms behind these effects are poorly understood. Male mice (4 wk old) were treated with BPA (50 or 500 μg/kg/d) for 8 wk. Whole-body glucose homeostasis, pancreatic islet morphology and function, and miR-338-mediated molecular signal transduction analyses were examined. We showed that BPA treatment led to a disruption of glucose tolerance and a compensatory increase of pancreatic islets insulin secretion and pancreatic and duodenal homeobox 1 (Pdx1) expression in mice. Inhibition of Pdx1 reduced glucose-stimulated insulin secretion and ATP production in the islets of BPA-exposed mice. Based on primary pancreatic islets, we also confirmed that miR-338 regulated Pdx1 and thus contributed to BPA-induced insulin secretory dysfunction from compensation to decompensation. Short-term BPA exposure downregulated miR-338 through activation of G-protein-coupled estrogen receptor 1 (Gpr30), whereas long-term BPA exposure upregulated miR-338 through suppression of glucagon-like peptide 1 receptor (Glp1r). Taken together, our results reveal a molecular mechanism, whereby BPA regulates Gpr30/Glp1r to mediate the expression of miR-338, which acts to control Pdx1-dependent insulin secretion. The Gpr30/Glp1r-miR-338-Pdx1 axis should be represented as a novel mechanism by which BPA induces insulin secretory dysfunction in pancreatic islets.-Wei, J., Ding, D., Wang, T., Liu, Q., Lin, Y.

Abstract
There have been several global epidemics of chronic kidney disease of unknown etiology (CKDu). Some, such as Itai-Itai disease in Japan and Balkan endemic nephropathy, have been explained, whereas the etiology of others remains unclear. In countries such as Sri Lanka, El Salvador, Nicaragua, and India, CKDu is a major public health problem and causes significant morbidity and mortality. Despite their geographical separation, however, there are striking similarities between these endemic nephropathies. Young male agricultural workers who perform strenuous labor in extreme conditions are the worst affected. Patients remain asymptomatic until end-stage renal failure. Biomarkers of tubular injury are raised, and kidney biopsy shows chronic interstitial nephritis with associated tubular atrophy. In many of these places access to dialysis and transplantation is limited, leaving few treatment options. In this review we briefly describe the major historic endemic nephropathies. We then summarize the epidemiology, clinical features, histology and clinical course of CKDu in Mesoamerica, Sri Lanka, India, Egypt, and Tunisia. We draw comparisons between the proposed etiologies and supporting research. Recognition of the similarities may reinforce the international drive to establish causality and to effect prevention.
