Excess body weight, duration of insulin and antihypertensive therapy slow down the rate of progression of chronic kidney disease in type 2 diabetes

Abstract

Objective: to study and clinically substantiate the relationship between overweight and the dynamics of CKD progression in patients with type 2 diabetes of different age groups using the diagnostic parameter Index of glomerular filtration rate reduction. Material and methods: a single-stage cross-sectional observational study of clinical indicators in a population sample of patients with type 2 diabetes of different age groups was performed, patterns of relationships, significance of differences in mean values and measures of influence (OR (95%CI)) were studied between the indicators of BMI, the stage of obesity and the presence of a diagnosis of obesity in the anamnesis and the original calculated diagnostic parameter, the Index of glomerular filtration rate reduction (RI_GFR), which allows to give an objective quantitative characteristic of the rate of progression of CKD. Results: significant correlations were established between RI_GFR and indicators of age, BMI, DM experience and duration of insulin therapy, a significant inverse relationship with BMI was noted only in the older group; when analyzing differences in the average values of clinical indicators in the groups of rapid and slow progression of CKD, divided by the threshold value of RI_GFR, significant factors affecting the rate of progression were determined CKD: DM experience, duration of insulin therapy, BMI; the logistic regression analysis determined the measure of the influence of the above factors on the dynamics of GFR reduction, confirmed its significance; when analyzing the factors of drug treatment in the elderly group, it was revealed that an integrated approach to the appointment of antihypertensive therapy (prescribing drugs of three or more groups) significantly reduces the risk of rapid progression of CKD. Conclusions: the most significant risk factors for the high rate of progression of CKD in patients with type 2 diabetes and overweight in the general sample and in patients of the older age group are the length of diabetes and duration of insulin therapy; the dynamics of GFR reduction in patients with type 2 diabetes of different age groups is interrelated with BMI, and in patients with overweight CKD progresses more slowly; an integrated approach to prescribing antihypertensive therapy (prescribing drugs of three or more groups) in elderly patients with type 2 diabetes significantly reduces the risk of rapid progression of CKD.
