Fibrates are widely used to treat hypertriglyceridemia, a risk factor for arteriosclerosis, but these compounds have been associated with renal dysfunction. This study aimed to investigate the effects of fibrates on renal function in relatively healthy adult subjects with no cardiovascular diseases.
This retrospective study included 558 outpatients who were prescribed 160 mg fenofibrate (fenofibrate group) or 10 mg atorvastatin (control group) between August 2007 and October 2015. The groups were randomly matched using propensity scores at a 1:1 ratio. Serum creatinine levels and estimated glomerular filtration rates before and after treatment were compared between the two groups.
Patients in the fenofibrate group showed greater changes in serum creatinine levels than those in the control group (9.73%±9.83% versus −0.89%±7.37%, P<0.001). Furthermore, 55.1% of patients in the fenofibrate group, but only 6.1% of those in the control group, exhibited a serum creatinine level increase ≥0.1 mg/dL (P<0.001). The fenofibrate group showed significantly greater declines in the estimated glomerular filtration rate than the control group (−10.1%±9.48% versus 1.42%±9.42%, P<0.001). Moreover, 34.7% of the fenofibrate group, but only 4.1% of the control group, exhibited an estimated glomerular filtration rate decrease ≥10 mL/min·1.73 m2 (P<0.001).
Fenofibrate treatment resulted in increased serum creatinine levels and reduced estimated glomerular filtration rates in a primary care setting. Therefore, regular renal function monitoring should be considered essential during fibrate administration.

The glomerular filtration rate (GFR) decreases with age, while parathyroid hormone (PTH) increases. There are a few reports only on the relationship between GFR and PTH under the category of serum 25-hydroxyvitamin D (25[OH]D) concentration.
Using the Korea National Health and Nutrition Examination Survey (KNHANES) data, a cross-sectional study was conducted on the association between serum 25(OH)D concentration, GFR and PTH in Korean adults aged 50 years or older. Serum PTH concentration was compared to the tertiles of GFR after adjustment for relevant variables. In addition, the serum PTH concentration was compared with the GFR under the category of serum 25(OH) D concentration (<20, 20-30, >30 ng/mL).
The mean estimated GFR (eGFR) was 74.8 mL/min in men and 73.1 mL/min in women. The mean PTH and 25(OH) D was 66.8 pg/mL, 20.5 ng/mL in men and 69.0 pg/mL, 18.2 ng/mL in women. The serum PTH concentration showed a significant negative correlation with the serum 25(OH) D and eGFR in both genders. The serum PTH concentration significantly increased at the lower tertile of eGFR in male adults In addition, a decrease of serum PTH concentration was marked in the vitamin D sufficient male adults (>30 ng/mL).
This present study demonstrated that serum PTH concentration showed negative correlation with eGFR, however, serum PTH increase may be minimized by maintaining proper serum 25(OH)D concentrations under similar eGFR status in Korean adults aged 50 and above.

Recent studies suggest that coffee consumption has an influence on kidney function. This study investigated the relationship between habitual coffee consumption and renal impairment in Korean women, in consideration of diabetic status.
This study involved 2,673 women aged 35 to 84 years who had participated in the Fourth Korea National Health and Nutrition Examination Surveys, conducted in 2008. Habitual coffee consumption was classified into three categories: less than 1 cup per day, 1 cup per day, and 2 or more cups per day. Renal function impairment was defined as an estimated glomerular filtration rate less than 60 mL/min/1.73 m2 by the Modification of Diet in Renal Disease equation.
The prevalence of diabetes and renal function impairment was higher in women who drank < 1 cup of coffee per day. Compared with drinking < 1 cup of coffee per day, the odds ratio (OR) for renal function impairment was significantly lower (OR, 0.59; 95% confidence interval [CI], 0.37 to 0.95; P = 0.03) in those who habitually drank ≥ 2 cups per day after adjusting for multiple confounding factors. When data were stratified according to the presence of diabetes, coffee consumption ≥ 2 cups of coffee per day showed an inverse association with renal function impairment in only diabetic women (OR, 0.14; 95% CI, 0.02 to 0.88; P = 0.04), compared with consumption < 1 cup of coffee per day.
In a representative sample of Korean women, coffee consumption was significantly associated with a decreased risk of renal impairment especially in middle and elderly-aged diabetic women.

Non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease (CKD) share common pathogenic mechanisms and many risk factors, and both are linked to an increased risk of cardiovascular diseases. The aim of this study was to assess the association between NAFLD and CKD according to the presence of hypertension and diabetes mellitus in Koreans aged 50 years or older.
A cross-sectional study of 1,706 subjects who received their routine health examination was conducted between May 2008 and April 2010 at Konkuk University medical center. Biochemical tests for liver and abdominal ultrasonography were performed. CKD was defined as either proteinuria or glomerular filtration rate ≤60 mL/min per 1.73 m2.
Among the 1,706 subjects, There were 545 (31.9%) with non-alcoholic fatty liver disease and 424 (24.9%) with chronic kidney disease. In univariate logistic regression analysis, NAFLD was significantly associated with CKD (odds ratio [OR], 1.69; 95% confidence interval [CI], 1.34 to 2.12). In multivariate logistic regression analysis adjusted for age, sex, current smoking, abdominal obesity, aspartate aminotransferases, alanine aminotransferases, γ-glutamyltransferase, hypertension, diabetes mellitus, hypertriglyceridemia, and low high-density lipoprotein cholesterol, NAFLD was associated with CKD (adjusted OR, 1.68; 95% CI, 1.27 to 2.24). This relationship remained significant after classification according to the presence of hypertension or diabetes mellitus.
NAFLD diagnosed by ultrasonography was significantly associated with CKD in Koreans aged 50 years or older.
