Abstract

Background: Diabetes mellitus type 2 (DMT2) and hyperuricemia are two prevalent metabolic diseases worldwide, including in Indonesia. In fact, in the Minahasa tribe, the prevalence of these diseases is among the highest in Indonesia. The interaction between hyperuricemia and DMT2 level is inconclusive, as previous studies about whether allopurinol and its related uric acid reduction correlate with insulin resistance have shown conflicting results.Objective: To examine whether allopurinol-induced uric acid reduction can modify insulin resistance in nondiabetic Minahasan male subjects and study the putative molecular mechanisms of this interaction.Methods: The clinical part of this research was a pseudo-experiment with a pre-test/post-test design. Twenty nondiabetic Minahasan male subjects were subjected to the daily dose of 300 mg allopurinol for three months. Plasma glucose, uric acid, and insulin levels were measured pre- and post-treatment. Homeostatic model assessment of insulin resistance (HOMA-ir) values were calculated by the Oxford HOMA calculator. For the wet lab experiment, the human embryonic kidney cell line was treated with tolerable allopurinol. The expression of glucose transporter 4 (Glut4) mRNA, an insulin-inducible glucose transporter was analyzed by quantitative real-time polymerase chain reaction (qPCR).Results: In nondiabetic Minahasan male subjects, allopurinol administration decreased uric acid serum level, but did not affect plasma glucose and insulin levels. In fact, there is a trend of increasing HOMA-ir among the subjects following allopurinol administration. In vitro, allopurinol treatment also did not increase Glut4 expression, suggesting that allopurinol's effect on diabetes control has other, complex mediative pathways.Conclusion: Allopurinol administration and its related uric acid plasma reduction does not significantly affect insulin resistance; a trend however exists that allopurinol and uric acid reduction increased HOMA-ir. At the molecular level, Glut4 expression is not affected by allopurinol.

Abstract

Background: Coal dust is an environmental factor contributing to the risk of respiratory diseases. However, clinical evidence on the effects of coal dust in lung remodelling is currently lacking, especially the effect of eosinophils and IL-13. This study investigates how eosinophil and IL-13 affect pulmonary remodeling in coal dust and asthma combination models.Methods: An experimental study was conducted using BALB/c mice aged 6 to 12 weeks with a weight range of 20-25 g. There were 10 mice in each of the three treatments. Groups were sensitized with normal saline, ovalbumin (OVA)-sensitized, and OVA-sensitized + coal dust. The parameters of lung remodeling (the thickness of epithelium, smooth muscle thickness, the number of goblet cells, and subepithelial fibrosis) and the number of eosinophils were measured with histomorphometry analysis. Total IL-13 concentrations were measured using an IL-13 ELISA kit. The data group of a combination of OVA + coal dust was analyzed using the path analysis method.Results:  From path analysis, it was found that Eosinophils (b=0.006; 95%CI=-2.594 to 2.606; p=0.000) had positive, direct, and statistically significant effects on IL-13. Eosinophil's indirect effect on epithelium thickness and subepithelial fibrosis thickness via IL-13. Interleukine-13 had positive, direct, and statistically significant effects on epithelium thickness (b=0.67; 95%CI=-0.129 to 1.471; p=0.010) and subepithelial fibrosis thickness (b=0.682; 95%CI=0.301 to 1.062; p=0.000).Conclusion: Eosinophils' indirect effect on lung remodeling via IL-13 and IL-13 directly affects airway remodeling, especially epithelium and subepithelial fibrosis components.

Abstract

Background: Chlorpyrifos is one of the organophosphate pesticide types frequently utilized as a pest control agent in Indonesia. Despite its effectiveness in combating pests, the residue levels of chlorpyrifos in the environment and plants have raised serious concerns. Long-term accumulation of chlorpyrifos in the body can lead to organ damage, particularly in the liver and kidneys, which may decrease serum albumin levels.Objective: To investigate the impact of low-dose chlorpyrifos exposure over time on serum albumin levels in Wistar rats.Methods: Thirty male Wistar rats were divided into five groups: the normal control group (Kn) received normal saline solution (+5% Tween 20) orally for 56 days, while the treatment groups (K1, K2, K3, and K4) were administered chlorpyrifos at a dose of 5 mg/kg body weight for 7 days (acute), 14 days (subacute), 28 days (subchronic), and 56 days (subchronic) orally. Serum albumin levels were measured using the dye-binding method with a spectrophotometer.Results: The measurement results indicate that the normal control group (Kn) had the highest serum albumin levels (4.326±0.519 g/dL). Serum albumin levels decreased in the groups treated with chlorpyrifos. The longer the chlorpyrifos exposure, the lower the serum albumin levels. The lowest serum albumin levels were found in group K4 with chlorpyrifos exposure for 56 days (2.826±0.358 g/dL). Statistical analysis using One-way ANOVA and Post Hoc LSD tests showed significant differences (p<0.05) between all treatment groups (K1, K2, K3, and K4) and the control group (Kn).Conclusion: This study shows that administering low-dose chlorpyrifos over a period of 7 to 56 days has a significant effect in reducing serum albumin levels in Wistar rats. The clinical implications of this decrease in serum albumin levels need to be considered in the context of exposure to organophosphate pesticide residues in humans.

Abstract

Background: Diabetes mellitus (DM) has been increasing worldwide. Obesity, especially central obesity, is a sign of increased visceral fat in various diseases, especially DM. Individuals with visceral fat compromise insulin resistance and metabolic disorders and develop diabetes. The gold standard for assessing insulin resistance is the hyperinsulinemic-euglycemic clamp (HEC). However, this method is invasive and expensive, so the homeostasis model assessment-insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) are more straightforward, more practical, and invasive measurement methods. Visceral adiposity index (VAI) was developed as a new indicator of visceral adipose tissue dysfunction that can be used for CT examination as a marker of visceral adiposity.Objective: To determine the correlation between visceral adiposity index and insulin resistance in patients with type 2 diabetes mellitusMethods: The study was conducted as an analytical observational study using a cross-sectional design approach at the Diponegoro National Hospital Semarang from March to April 2022. Data analysis using the Pearson test (meaningful if p < 0.05)Results: From the 70 samples examined, there was a correlation between VAI and HOMA-IR (r=0,480; p=<0,001), VAI and QUICKI (r=-0,475; p=<0,001), and a strong correlation between HOMA-IR and QUICKI (r=-0,892; p=<0,001)Conclusion: There was a moderate positive correlation between VAI and HOMA-IR and a moderate negative correlation between VAI and QUICKI. Meanwhile, the results of the correlation test between HOMA-IR and QUICKI show that there is a robust negative correlation.
