Study of Genome-associated Mechanisms of Diabetic Nephropathy and Evaluation of Nephroprotective Therapy in Patients With Type 2 Diabetes Mellitus in the Kazakh Population

The incidence of diabetes remains a serious global health issue, demanding close attention and the development of comprehensive strategies for prevention, early diagnosis, and effective treatment . According to the International Diabetes Federation (IDF), in 2021, the number of people with diabetes reached 537 million, and it is projected to rise to 783 million by 2045. In the Asia-Pacific region, the number of people with diabetes has reached approximately 206 million .

One of the most common complications of diabetes is diabetic nephropathy. In developed countries, such as the United States and European nations, diabetic nephropathy is a leading cause of chronic kidney disease, placing a significant burden on the healthcare system.

In light of this, the development of more effective methods for early detection of diabetic nephropathy remains a relevant objective. Current research focuses extensively on identifying kidney biomarkers that can signal early kidney damage in the disease's initial stages. Moreover, in recent years, genome-wide association studies (GWAS) have shown that diabetic nephropathy has a genetic component and that susceptibility may vary among different ethnic groups. This underscores the need to develop personalized treatments that consider patients' genetic characteristics.

In emerging economies, such as Kazakhstan, the issue of diabetic nephropathy is also becoming increasingly relevant. The rise in diabetes cases, especially in urban populations, has led to a growing number of chronic kidney disease cases and associated disabilities. This results in significant economic costs for the healthcare system, as the treatment of end-stage renal disease patients requires considerable resources. In Kazakhstan, a particularly important aspect is the lack of studies focused on the genetic and clinical characteristics of diabetic nephropathy in the local population.

The project is particularly valuable due to its emphasis on the Kazakh population, which is underrepresented in global studies. This focus allows for the identification of risk factors and specific characteristics of diabetic nephropathy unique to this ethnic group. Such an approach will substantially enhance the country's scientific and technical capacity and boost Kazakhstan's competitiveness on the international scientific stage.

Given the above, research into genome-associated mechanisms of diabetic nephropathy and evaluation of the effectiveness of nephroprotective therapy in patients with type 2 diabetes within the Kazakh population represent scientific novelty and practical significance. Such studies will help improve the effectiveness of therapeutic and rehabilitation measures, contribute to identifying genetic variations specific to the Kazakh population, and improve patients' quality of life. This will also have a positive impact on healthcare economics and enhance patients' quality of life, while contributing to the global genetic data regarding the Kazakh population.

About this study

To achieve the goal of the project, the following tasks were formulated, consisting of a subset of direct sequences designed to consistently lead to results. The study of genome-associated mechanisms of diabetic nephropathy and the evaluation of the effectiveness of nephroprotective therapy in patients with type 2 diabetes mellitus in the Kazakh population may provide new diagnostic opportunities and influence treatment options for patients, and this hypothesis has been tested on five proposed tasks:

Recruiting research participants.

Make a list of potential participants
Invitation of respondents of Kazakh nationality
Obtaining written informed consent. A preliminary list of project participants will be created together with endocrinologists. The invitation will be carried out by dialing through the list of participants. A written agreement will be received after the participants have familiarized themselves with the progress of the study.
Working with respondents.

Collecting anamnesis of the disease and life
Clinical and diagnostic examination of the study participants. Clinical and diagnostic examinations will be conducted for all participants of the study, as a result of which participants will be selected according to the inclusion and exclusion criteria. As a result, a database of study participants will be created.
Conducting a genetic study and a study of the tubular function of the project participants. Glycation genes will be examined from the venous blood samples of the study participants and markers of tubular function such as beta-2 microglobulin, albumin creatinine ratio and Ngal (neutrophil gelatinase-associated lipocalin) will be studied based on urine analysis.
The analysis of the results obtained and the study of the effectiveness of nephroprotective therapy in dynamics in the studied patients.
Interpretation and publication of the results. Based on the results of this study, articles will be prepared for international peer-reviewed journals (with a non-zero impact factor): at least 2 (two) articles in journals from the first three quartiles by impact factor in the Web of Science database or having a CiteScore percentile in the Scopus database of at least 50.
