Abstract Background Strategies to prevent the development and progression of chronic kidney disease (CKD) are now an important theme in clinical practice due to increased life expectancy. The present study investigated the prevalence of CKD as well as lipid profiles affecting CKD. Methods In total, 5,169 subjects were eligible for a cross-sectional analysis of baseline data from the Jichi Medical School Cohort Study. We examined CKD subjects with an estimated glomerular filtration rate (eGFR) of 59 (mL/min/1.73m2) or lower and independent factors associated with reductions in eGFR. Results The prevalence of CKD was 17.7%. Age, systolic blood pressure, and hyperlipidemia were defined as related factors for CKD. The lowest, second, third, and highest quartile ranges of total cholesterol (TC) and triglycerides (TG) were 0-166, 167–188, 189–212, and 213 mg/dL or higher and 0–71, 72–100, 101–148, and 149 mg/dL or higher, respectively. The odds ratio (OR) of Q2 to Q4 of TC relative to that of Q1 for CKD increased linearly [OR (95%CI): Q2, 1.3 (1.0-1.7); Q3, 1.38 (1.1–1.8); Q4, 1.5 (1.4–2.4)]. The ORs of Q2 and Q3 of TG for CKD did not increase, whereas that of Q4 did [OR (95% CI): Q2, 0.95 (0.7–1.2); Q3, 0.98 (0.8–1.2); Q4, 1.21 (1.0-1.5)]. Conclusion TC and TG elevations were both independently associated with CKD. The relationship with CKD became stronger as TC increased, and TG was considered to have a threshold of 149 mg/dL. Prospective studies are expected in the future.

Abstract Background: Strategies to prevent the development and progression of chronic kidney disease (CKD) are important in clinical practice due to increased life expectancy. The present study investigated the prevalence of CKD as well as lipid profiles affecting CKD, especially triglyceride (TG) levels.Methods: In total, 5,169 subjects were eligible for a cross-sectional analysis of baseline data from the Jichi Medical School Cohort Study. We examined CKD subjects with an estimated glomerular filtration rate (eGFR) of 59 mL/min/1.73m2 or lower and independent factors associated with reductions in eGFR.Results: The prevalence of CKD was 17.7%. Age, systolic blood pressure, and hyperlipidemia were defined as related factors for CKD. The lowest, second, third, and highest quartile ranges of total cholesterol (TC) and TG were 0-166, 167-188, 189-212, and 213 mg/dL or higher and 0-71, 72-100, 101-148, and 149 mg/dL or higher, respectively. The odds ratio (OR) of Q2 to Q4 of TC relative to that of Q1 for CKD increased linearly (OR [95%CI]: Q2, 1.3 [1.0-1.7]; Q3, 1.38 [1.1-1.8]; Q4, 1.5 [1.4-2.4]). The ORs of Q2 and Q3 of TG for CKD did not increase, whereas that of Q4 did (OR [95% CI]: Q2, 0.95 [0.7-1.2]; Q3, 0.98 [0.8-1.2]; Q4, 1.21 [1.0-1.5]). Conclusion: Increases in TC and TG levels were both independently associated with CKD. The relationship with CKD became stronger as TC increased, and the TG had threshold was 149 mg/dL.

(1) Background: Individuals with diabetes and chronic kidney disease display gut dysbiosis when compared to healthy controls. However, it is unknown whether there is a change in dysbiosis across the stages of diabetic chronic kidney disease. We investigated a cross-sectional study of patients with early and late diabetes associated chronic kidney disease to identify possible microbial differences between these two groups and across each of the stages of diabetic chronic kidney disease. (2) Methods: This cross-sectional study recruited 95 adults. DNA extracted from collected stool samples were used for 16S rRNA sequencing to identify the bacterial community in the gut. (3) Results: The phylum Firmicutes was the most abundant and its mean relative abundance was similar in the early and late chronic kidney disease group, 45.99 ± 0.58% and 49.39 ± 0.55%, respectively. The mean relative abundance for family Bacteroidaceae, was also similar in the early and late group, 29.15 ± 2.02% and 29.16 ± 1.70%, respectively. The lower abundance of Prevotellaceae remained similar across both the early 3.87 ± 1.66% and late 3.36 ± 0.98% diabetic chronic kidney disease groups. (4) Conclusions: The data arising from our cohort of individuals with diabetes associated chronic kidney disease show a predominance of phyla Firmicutes and Bacteroidetes. The families Ruminococcaceae and Bacteroidaceae represent the highest abundance, while the beneficial Prevotellaceae family were reduced in abundance. The most interesting observation is that the relative abundance of these gut microbes does not change across the early and late stages of diabetic chronic kidney disease, suggesting that this is an early event in the development of diabetes associated chronic kidney disease. We hypothesise that the dysbiotic microbiome acquired during the early stages of diabetic chronic kidney disease remains relatively stable and is only one of many risk factors that influence progressive kidney dysfunction.

Background and objectives: Chronic kidney disease (CKD) in children is a complex medical and social issue around the world. One of the serious complications is mineral-bone disorder (CKD-MBD) which might determine the prognosis of patients and their quality of life. Fibroblast growth factor 23 (FGF-23) is a phosphaturic hormone which is involved in the pathogenesis of CKD-MBD. The purpose of the study was to determine what comes first in children with CKD: FGF-23 or phosphate. Materials and Methods: This cross-sectional study included 73 children aged 2–18 years with CKD stages 1–5. We measured FGF-23 and other bone markers in blood samples and studied their associations. Results: Early elevations of FGF-23 were identified in children with CKD stage 2 compared with stage 1 (1.6 (1.5–1.8) pmol/L versus 0.65 (0.22–1.08), p = 0.029). There were significant differences between the advanced stages of the disease. FGF-23 correlated with PTH (r = 0.807, p = 0.000) and phosphate (r = 0.473, p = 0.000). Our study revealed that the elevated level of FGF-23 went ahead hyperphosphatemia and elevated PTH. Thus, more than 50% of children with CKD stage 2 had the elevating level of serum FGF-23, and that index became increasing with the disease progression and it achieved 100% at the dialysis stage. The serum phosphate increased more slowly and only 70.6% of children with CKD stage 5 had the increased values. The PTH increase was more dynamic. Conclusions: FGF-23 is an essential biomarker, elevates long before other markers of bone metabolism (phosphate), and might represent a clinical course of disease.
