Ckd Stage

In the early 1980s, studies in type 1 diabetes suggested that glomerular filtration rate (GFR) loss begins with the onset of macroalbuminuria. However, recent evidence indicates that up to one-quarter of subjects with diabetes reach a GFR of less than 60 ml/min/1.73 m2(chronic kidney disease [CKD] stage 3) before developing micro- or macroalbuminuria. Furthermore, the prospective loss of GFR can be detected in early diabetic nephropathy (DN) well before CKD stage 3. Early GFR loss usually reflects DN in type 1 diabetes but, in older patients with type 2 diabetes, the assessment of early GFR loss needs to take into account the effects of aging. The assessment of GFR is now feasible at clinical level, using formulas based on serum creatinine, age, gender, and ethnicity. Overall, the estimation of early GFR loss is more accurate with the Chronic Kidney Disease Epidemiology (CKD–EPI) formula than with the Modification of Diet in Renal Disease (MDRD) study formula, but there is some evidence that the CKD-EPI formula does not exhibit better performance than the MDRD formula for estimating GFR in diabetes. Both formulas underestimate GFR in the hyperfiltration range. Formulas based on the reciprocal of cystatin C can also be used to estimate GFR, but their cost and lack of assay standardization have delayed their use at clinical level. In summary, early GFR loss is an important marker of DN as well as a potentially reversible target for interventions in DN.

One-third of diabetes mellitus patients develop diabetic nephropathy, and with underlying mechanisms unknown it is imperative that diabetic animal models resemble human disease. The present study investigated the susceptibility to develop diabetic nephropathy in four commonly used and commercially available mouse strains with type 1 diabetes to determine the suitability of each strain. Type 1 diabetes was induced in C57Bl/6, NMRI, BALB/c, and 129Sv mice by alloxan, and conscious glomerular filtration rate, proteinuria, and oxidative stress levels were measured in control and diabetic animals at baseline and after 5 and 10 wk. Histological alterations were analyzed using periodic acid-Schiff staining. Diabetic C57Bl/6 displayed increased glomerular filtration rate, i.e., hyperfiltration, whereas all other parameters remained unchanged. Diabetic NMRI developed the most pronounced hyperfiltration as well as increased oxidative stress and proteinuria but without glomerular damage. Diabetic BALB/c did not develop hyperfiltration but presented with pronounced proteinuria, increased oxidative stress, and glomerular damage. Diabetic 129Sv displayed proteinuria and increased oxidative stress without glomerular hyperfiltration or damage. However, all strains displayed intrastrain correlation between oxidative stress and proteinuria. In conclusion, diabetic C57Bl/6 and NMRI both developed glomerular hyperfiltration but neither presented with histological damage, although NMRI developed low-degree proteinuria. Thus these strains may be suitable when investigating the mechanism causing hyperfiltration. Neither BALB/c nor 129Sv developed hyperfiltration although both developed pronounced proteinuria. However, only BALB/c developed detectable histological damage. Thus BALB/c may be suitable when studying the roles of proteinuria and histological alterations for the progression of diabetic nephropathy.

Diabetic Patients

Diabetic kidney disease develops in approximately 40% of patients who are diabetic and is the leading cause of chronic kidney disease worldwide. The majority of patients actually die from cardiovascular diseases and infections before needing kidney replacement therapy. The progression of fibrotic processes in the diabetic kidneys occurs with the participation of universal mediators of inflammation. Given the clinical and social significance of diabetic kidney damage, the determination of interleukin-1β and interleukin-6 in blood serum may expand the understanding of this problem, as well as help in the development of individualized therapeutic approaches. The purpose of the study is to investigate interleukin-1β and interleukin-6 levels in the serum of patients with type 2 diabetes mellitus, depending on kidney functional state in the dynamics of therapy and with additional prescription of dapagliflozin. Materials and methods. 72 patients with type 2 diabetes were examined. The control group consisted of 20 healthy individuals. The patients were divided into the following groups: group I – type 2 diabetic patients with normal glomerular filtration rate and without albuminuria (n = 25); group II – patients with type 2 diabetes with normal glomerular filtration rate and albuminuria (n = 23); group III – patients with type 2 diabetes with decreased glomerular filtration rate and albuminuria (n = 24). The complex pathogenetic therapy of patients of group 1 included renin-angiotensin-aldosterone system blockers, metformin and hypolipidemic agents. Patients of group 2 were additionally prescribed dapagliflozin. The control was carried out after 6 months. Results and discussion. According to the results of the study, the development of diabetic nephropathy in patients with type 2 diabetes is accompanied by a significant increase in the level of interleukin-1β and interleukin-6 in the blood plasma compared with the control and in patients with diabetes without signs of nephropathy. Nephroprotective therapy contributed to a significant decrease of interleukin-1β and interleukin-6 levels in the blood serum in all groups of patients. The highest response to treatment was observed in patients with diabetic nephropathy and albuminuria. Most significant decrease of albuminuria, normalization of blood pressure and lipid spectrum improvement were observed in patients with the initial stages of the disease. Additional using of dapagliflozin leads to a more significant decrease in the content of proinflammatory cytokines in the blood serum of patients with type 2 diabetes mellitus with diabetic nephropathy. Conclusion. The results of the study indicate the advisability of using interleukin-1β and interleukin-6 as a diagnostic marker of cardiac disorders, assessment of prognosis, and improvement of the cardionephroprotective strategy in diabetic patients. The therapeutic potential of dapagliflozin in the treatment of diabetic nephropathy and the prevention of cardiovascular events in patients with diabetes is of great scientific interest and requires further research

Abstract Objectives Diabetic nephropathy is a serious and a common complication of diabetes that can lead to end stage renal disease among children living with type 1 diabetes, thus an early and accurate method of diagnosis that allows timely intervention is of high importance. This study aimed to evaluate the role of magnetic resonance diffusion weighted imaging in diagnosis of diabetic nephropathy in children with type 1 diabetes. Methods This prospective, observational, case control study included 30 children with type 1 diabetes and 30 matched healthy controls attending the outpatient clinics in Mansoura University Children’s Hospital. All were subjected to magnetic resonance DWI of the renal parenchyma and their glomerular filtration rate (GFR) was estimated, along with micro albumin in 24 h urine collection and HbA1c in patients with diabetes. Results Children with diabetes who were positive for microalbuminuria had significantly lower apparent diffusion coefficient value compared to Children with diabetes who were negative for microalbuminuria (p = 0.034) as well as controls (p = 0.001). Among children with type 1 diabetes, apparent diffusion coefficient had significant positive correlation with estimated glomerular filtration rate (r = 0.491, p = 0.006) and negative correlation with microalbuminuria (r = −0.437, p = 0.016). Conclusion Magnetic resonance DWI of the renal parenchyma is correlated with estimated glomerular filtration rate (eGFR) in children with type 1 diabetes and can detect GFR deterioration even in presence of normal albumin excretion.
