The Relationship Between the Level of Serum 25-Hydroxyvitamin D and Renal Function in Patients Without Chronic Kidney Disease: A Cross-Sectional Study

Abstract Background: Studies have shown that serum 25-hydroxyvitamin D (25(OH)D), a product of exogenous vitamin D, plays an influential role in calcium and phosphorus balance, anti-inflammation, and cardiovascular protection. There were long-standing interests in the potential benefits of vitamin D for preventing liver diseases. Investigations showed that 25(OH)D was increased in adolescents with abnormal liver function. Yet data about the relationship of 25(OH)D concentration and liver enzymes from prospective cross-sectional study was limited. The present study is undertaken to examine whether serum 25-hydroxyvitamin D and alanine aminotransferase (ALT) ，glutamyl transferase (GGT) and alkaline phosphatase (ALP) were closely related. Methods: The cross-sectional study of 368 healthy volunteers with no history of liver diseases was used to examine risk factors. The associations between ALT, G and ALP and 25(OH)D were assessed by Pearson correlation and Spearman correlation, respectively. Linear regression analysis was carried out in different models with ALT, GGT and ALP as dependent variables. Results: The results found no significant difference between ALT and ALP in different vitamin D groups (25(OH)D < 25 nmol/L、25-50 nmol/L and > 50 nmol/L) ( Kruskal-Wallis test, all p > 0.05 ). Multiple linear regression analysis revealed that there were no significant association between ALT, GGT and ALP levels and 25(OH)D concentration, respectively, after adjusting covariates including age, BMI, sex, BuN, Cr, UA, AST, Ghb, ALB, WBC, cholesterol, HDL, LDL, cholesterol, and total protein. (All p > 0.1). Conclusion: This study suggested that there was no association between the 25(OH)D concentration and the levels of ALT, GGT or ALP in normal population.

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.

Yet data about the relationship of 25(OH)D concentration and liver enzymes from prospective cross-sectional study was limited. The present study is undertaken to examine whether serum 25-hydroxyvitamin D and glutamyl transferase (GGT), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were closely related. Methods The cross-sectional study of 368 healthy volunteers with no history of liver diseases was used to examine risk factors. Pearson correlation (or Spearman correlation for skewed variables) was performed to assess associations between GGT, ALT, and ALP and 25(OH)D. Linear regression analysis was conducted with GGT, ALT, and ALP as dependent variables in separate models. Results The results found no significant difference between ALT and ALP in different vitamin D groups (25(OH)D < 25 nmol/L、25-50 nmol/L and > 50 nmol/L) (Kruskal-Wallis test, all p > 0.05). In multiple linear regression analysis, GGT, ALT and ALP levels remained unrelated to 25(OH)D concentration after adjusting covariates including age, BMI, sex, BuN, Cr, UA, AST, Ghb, ALB, WBC, cholesterol, HDL, LDL, cholesterol, and total protein. (All p > 0.1). Conclusion This study suggested that there was no association between the 25(OH)D concentration and the levels of GGT, ALT or ALP in normal population.

Abstract Introduction: Hypertension (HT) and diabetes mellitus (DM) lead to functional and structural changes in target organs such as the kidneys, characterizing the need for preventive actions to avoid Chronic Kidney Disease (CKD). Objective: To verify cardiologists’ and endocrinologists’ knowledge, indications and practices regarding prevention of CKD in patients with HT and DM. Methods: A cross-sectional study with 14 cardiologists and 5 endocrinologists applying a questionnaire about the conduct of these professionals regarding the prevention of CKD in hypertensive and diabetic patients. Results: One hundred percent of the cardiologists and endocrinologists did not request specific tests for CKD screening (albuminuria and glomerular filtration rate (GFR), although 92.9% of the cardiologists and 60.0% of the endocrinologists report referring hypertensive and diabetic patients with impaired renal function to nephrologists. One hundred percent of the interviewees recognize the importance of physical exercise for their patients; however, only 68.6% of cardiologists and 60% of endocrinologists indicated a physiotherapist and/or physical trainer to implement these exercises. Conclusion: The professionals evaluated in this study do not request microalbuminuria and GFR examinations for hypertensive and diabetic patients as a follow-up routine, despite having found cases of renal function impairment in these patients; in contrast to what is proposed in the guidelines for hypertension and diabetes mellitus. They recognize the importance of physical exercise and report indicating their patients to a physiotherapist and/or physical trainer. We suggest continuing the study in order to ascertain the reasons for their not complying with the respective guidelines.
