Association of Polymorphisms in Antioxidant Enzyme-Encoding Genes with Diabetic Nephropathy in a Group of Saudi Arabian Patients with Type II Diabetes Mellitus.

ABSTRACT:

Introduction

An imbalance between reactive oxygen species (ROS) generation and the defence mechanisms underlying the activity of antioxidant enzymes has been demonstrated as the leading pathology in diabetes mellitus (DM)-related microvascular complications.

Purpose

This study aims to evaluate the association between polymorphisms in antioxidant enzyme-encoding genes: catalase (CAT); manganese superoxide dismutase (Mn-SOD); glutathione S transferase M1 (GSTM1); and GSTT1 glutathione S transferase T1 (GSTT1), and the risk of type II diabetic nephropathy (DN) in the Saudi population.

Patients and methods

The present study involved 64 type II DM patients with nephropathy and 64 type II diabetes patients without nephropathy from the King Abdulaziz University (KAU) Hospital. They underwent real-time PCR genotyping for the Mn-SOD and CAT genes. Multiplex PCR was used to detect GSTM1- and GSTT1-null polymorphisms.

Results

A statistically significant difference was observed between the case and control groups with regard to polymorphisms in the CAT gene (P = 0.037), but not for polymorphisms in the Mn-SOD (P = 0.64) gene. In addition, a statistically significant association was observed between null polymorphisms of the GSTT1 and GSTM1 genes and DN in the case and control groups (P = 0.046 and P = 0.035, respectively).

Conclusion

Our results showed that the genetic ability to combat oxidative stress may play a major role in DN pathogenesis in Saudi type II DM patients. These polymorphisms in antioxidant enzyme-encoding genes could be used as independent genetic markers for the construction of risk prediction models for kidney-related complications in type II DM patients.

Project description:IntroductionDiabetic retinopathy (DR) is the leading cause of preventable blindness in Saudi Arabia. With a prevalence of up to 40% of patients with diabetes, DR constitutes a significant public health burden on the country. Saudi Arabia has not yet established a national screening program for DR. Mounting evidence shows that Artificial intelligence (AI)-based DR screening programs are slowly becoming superior to traditional screening, with the COVID-19 pandemic accelerating research into this topic as well as changing the outlook of the public toward it. The main objective of this study is to evaluate the perception and acceptance of AI in DR screening among eye care professionals in Saudi Arabia.MethodsA cross-sectional study using a self-administered online-based questionnaire was distributed by email through the registry of the Saudi Commission For Health Specialties (SCFHS). 309 ophthalmologists and physicians involved in diabetic eye care in Saudi Arabia participated in the study. Data analysis was done by SPSS, and a value of p < 0.05 was considered significant for statistical purposes.Results54% of participants rated their level of AI knowledge as above average and 63% believed that AI and telemedicine are interchangeable. 66% believed that AI would decrease the workforce of physicians. 79% expected clinical efficiency to increase with AI. Around 50% of participants expected AI to be implemented in the next 5 years.DiscussionMost participants reported good knowledge about AI. Physicians with more clinical experience and those who used e-health apps in clinical practice regarded their AI knowledge as higher than their peers. Perceived knowledge was strongly related to acceptance of the benefits of AI-based DR screening. In general, there was a positive attitude toward AI-based DR screening. However, concerns related to the labor market and data confidentiality were evident. There should be further education and awareness about the topic.
