Diabetic nephropathy is a common complication of diabetes mellitus and is the leading cause of chronic kidney disease. Glycemic and blood pressure control constitute the main strategies of diabetic nephropathy prevention and treatment. However, despite current therapies, nephropathy progresses to renal failure and end-stage renal disease in many patients. Therefore, new therapeutic strategies targeting different pathophysiological mechanisms are needed. This review article briefly summarizes the standard therapy for diabetic nephropathy and also describes recent advances in potential renoprotective agents that could be used to prevent the development or progression of diabetic nephropathy.

OBJECTIVE: To assess the changes in the coagulation profiles of patients with chronic kidney disease (CKD) using thromboelastography (TEG) and identify the risk factors of hypercoagulation in CKD patients. METHODS: A total of 128 patients with CKD admitted in Hunan Provincial People's Hospital between August, 2018 and May, 2019 were recruited. The results of conventional coagulation test and TEG were compared between patients with CKD and 21 healthy control adults. The patients with CKD were divided into hypercoagulation group with a maximum amplitude (MA) > 68 mm (=66) and non-hypercoagulation group (MA≤68 mm, =62). The laboratory indicators were compared between the groups, and the factors affecting the hypercoagulable state in patients with CKD were analyzed. RESULTS: The levels of fibrinogen and D-Dimer increased significantly in patients with CKD at different stages as compared with the control subjects ( < 0.05). In the patients with CKD, the reaction time and K time decreased while MA, α-angle and coagulation index increased significantly in patients in stage 3-4 and those in stage 5 either with or without hemodialysis compared with the control group ( < 0.05). The estimated glomerular filtration rate (eGFR), percentage of patients with diabetes mellitus, history of stroke, percentage of neutrophils, neutrophil-lymphocyte ratio, red blood cell count, hemoglobin levels, platelet count, serum creatinine, serum cystatin-C, serum albumin, and lipoprotein (a) all differed significantly between hypercoagulation group and non-hypercoagulation group ( < 0.05). The eGFR, platelet count and hemoglobin levels were identified as independent factors affecting hypercoagulability in patients with CKD ( < 0.05). CONCLUSIONS s The hypercoagulable state of patients with CKD worsens gradually with the disease progression, and eGFR, platelet count and hemoglobin levels are all risk factors for the hypercoagulable state in patients with CKD.

The effect of food consumption on blood pressure during hemodialysis was examined in relatively younger 10 nondiabetic patients with end stage renal disease who were free from autonomic dysfunction. A balanced diet(300 Cal) was given after 1 hour of hemodialysis. Fed and fasting treatments were randomly assigned, three times respectively, in each patient. Systolic(p=0.006), diastolic(p=0.08) and mean blood pressures fell faster in the 30-minute postprandial period in the fed treatments compared with those of equivalent times in the fasting treatments. For each of these changes, two-way repeated measures analysis of variance revealed neither significant time effect, nor significant treatment effect, nor significant interaction between time(before vs. after meal) and treatment(fed vs. fasting). These results suggest that food ingestion during hemodialysis dose not cause significant hypotension in relatively younger patients with end stage renal failure on chronic hemodialysis in the absence of autonomic dysfunction.

Hypertension affects the majority of patients with chronic kidney disease (CKD) and increases the risk of cardiovascular disease, end-stage renal disease and mortality. Previously, many hypertension guidelines have suggested blood pressure targets in patients with CKD. Recently, the American College of Cardiology/American Heart Association 2017 Guideline for Hypertension suggests a new definition for hypertension and therapeutic targets, which were equally applicated to patients with CKD. These changes reflect the results of the Systolic Blood Pressure Intervention Trial (SPRINT) study, but the renal outcome of intensive blood pressure control was not good. Furthermore, the majority of hypertension guidelines including those of the Korean Society of Hypertension and the European Society of Hypertension have retained the traditional definition. Herein, we intend to analyze in detail the effect of intensive blood pressure control on kidney through the post-hoc analyses of the SPRINT study.

Septic pulmonary embolism (SPE) is different from non-infectious thromboembolism in that it causes pulmonary arterial obstruction and inflammation by infectious emboli from various sources. There are increased risks of SPE in patients with chronic kidney disease because of decreased immunity and frequent venous puncture with the use of indwelling venous catheters or arterio-venous graft (AVG). However, SPE related with AVG infection in end-stage renal failure patient is very rare. Recently, we experienced a typical case of septic pulmonary embolism occurring in a 57-year-old man with infected AVG during hemodialysis. The patient had started hemodialysis 10 years ago due to diabetic end stage renal failure. Due to functional failure of the arterio-venous fistula, hemodialysis had been performed through an AVG on the upper left arm 3 years before admission.

OBJECTIVES: End-stage renal disease (ESRD), which is primarily a consequence of diabetes mellitus, shows an exemplary health disparity between African American and Caucasian patients in the United States. Because diabetic chronic kidney disease (CKD) patients of these two groups show differences in their medical problems, the markers leading to ESRD are also expected to differ. The purpose of this study was, therefore, to compare their medical complications at various levels of kidney function and to identify markers that can be used to predict ESRD. METHODS: The data of type 2 diabetic patients was obtained from the 2012 Cerner database, which totaled 1,038,499 records. The data was then filtered to include only African American and Caucasian outpatients with estimated glomerular filtration rates (eGFR), leaving 4,623 records. A priori machine learning was used to discover frequently appearing medical problems within the filtered data. CKD is defined as abnormalities of kidney structure, present for >3 months. RESULTS: This study found that African Americans have much higher rates of CKD-related medical problems than Caucasians for all five stages, and prominent markers leading to ESRD were discovered only for the African American group. These markers are high glucose, high systolic blood pressure (BP), obesity, alcohol/drug use, and low hematocrit. Additionally, the roles of systolic BP and diastolic BP vary depending on the CKD stage. CONCLUSIONS: This research discovered frequently appearing medical problems across five stages of CKD and further showed that many of the markers reported in previous studies are more applicable to African American patients than Caucasian patients.

Anemia is common in Diabetes Mellitus (DM) with chronic kidney disease. Recent research suggests that DM itself also may be a risk factor of anemia even though kidney failure causes anemia. However, it has not been reported that the impact of DM on anemia in representative data of Korean population. A total of 5,417 Korean adults aged 20 years and older (2,328 men, 3,089 women) were selected from the participants of the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) for this study. Anemia was defined as hemoglobin (Hb) < 13 g/dL and hematocrit (Hct) < 39% for men or Hb < 12 g/dL and Hct < 36% for women. DM was defined as a fasting blood glucose > or = 126 mg/dL. Korean adults with anemia had a higher prevalence of DM than in normal adults (11.4 vs 7.5%; p < 0.0001). The unadjusted odds ratio (OR) for anemia was greater in Korean men with DM than in normal men (OR = 4.25; 95% CI: 2.48-7.29). This results did not differ after adjustment for the putative risk factors for anemia including chronic disease (OR = 2.64; 95% CI: 1.45-4.83). However, the presence of DM was not related with anemia in Korean women. In conclusion, this study revealed that DM might be an independent risk factor for anemia in Korean men. Identification and management for anemia are needed in Korean population with DM as well.

OBJECTIVE: To compare the effect of two different hand exercises on hand strength and vascular maturation in patients who underwent arteriovenous fistula surgery. METHODS: We recruited 18 patients who had chronic kidney disease and had undergone arteriovenous fistula surgery for hemodialysis. After the surgery, 10 subjects performed hand-squeezing exercise with GD Grip, and other 8 subjects used Soft Ball. The subjects continued the exercises for 4 weeks. The hand grip strength, pinch strength (tip, palmar and lateral pinch), and forearm circumference of the subjects were assessed before and after the hand-squeezing exercise. The cephalic vein size, blood flow velocity and volume were also measured by ultrasonography in the operated limb. RESULTS: All of the 3 types of pinch strengths, grip strength, and forearm circumference were significantly increased in the group using GD Grip. Cephalic vein size and blood flow volume were also significantly increased. However, blood flow velocity showed no difference after the exercise. The group using Soft Ball showed a significant increase in the tip and lateral pinch strength and forearm circumference. The cephalic vein size and blood flow volume were also significantly increased. On comparing the effect of the two different hand exercises, hand-squeezing exercise with GD Grip had a significantly better effect on the tip and palmar pinch strength than hand-squeezing exercise with Soft Ball. The effect on cephalic vein size was not significantly different between the two groups. CONCLUSION: The results showed that hand squeezing exercise with GD Grip was more effective in increasing the tip and palmar pinch strength compared to hand squeezing exercise with soft ball.
