Abstract

Metabolic syndrome may relate to pathogenesis of chronic kidney disease (CKD). There is scarce data with regard to thatphenomenon in Indonesian general population. We conduct a study to determine the prevalence of metabolic syndrome and itsrelationship with CKD individuals in general population of Legian Village, Bali. An analytical cross sectional study was carriedout in the community of Legian Village, a tourist destination in Bali. Samples were selected through simple random sampling.Two hundred and eighty four samples (117 males and 107 females, aged 46.1 ± 10.02 years) were included. Prevalenceof hypertension, hypertrigliseridemia, hypoHDL-cholesterol, central obesity, impaired fasting glucose (IFG), obese and CKDwas 14.1%, 38.4%, 25%, 18%, 11.6%, 51.8% and 11.6% respectively. Using bivariate analysis, there were strong and significantrelationship between hypertension (OR 2.6, 95%CI 1.12 to 6.19, p = 0.02) and IFG (OR 5.21; 95%CI 2.23 to 12.13, p = 0.00) withCKD. Using multivariate logistic regression entering those components of metabolic syndrome into the model, it was consistentlyfound that hypertension and DM is the associated factors for CKD in the population. There was increasing odds of CKD about1,0-fold every augment of metabolic syndrome components (OR 1.098; 95%CI 0.83 to 1.44). As our conclusion, hypertensionand IFG are associated factor for CKD in general population. Multiple components increased risk factor for CKD.

Abstract

Cardiovascular disease is a major complication for patents with reduced kidney function. Neopterin is well known as abiomarker for cardiovascular disease, however it is not clear whether it is associated with reduced kidney function. Study wascarried out in a Legian Kuta village a tourist town in Bali. Samples were underwent a series of interview, physical examinationand were taken blood samples for neoperin and creatinine tests. Neoptein concentrations were tested for its normal distributionand associated with C-G formula for estimated glomerular filtration rate. Cut-off value for prediction of reduced renal functionwas rested using ROC curve, and calculated for sensitivity, specificity.Seventy nine samples were selected through cluster random sampling from 284 residents (177 males and 107 females)with age 46 ± 10 years, body weight 67 ± 13 kg and height 162 ± 9 cm. It was shown that neopterin concentration was normallydistributed (K-S Z = 1.175, p = 0.126), with mean 6.66 ± 3.35 ng/ml and e-GFR was 89 ± 25 ml/mnt. There was significantnegatively correlation between neopterin concentrations and e-GFR (R = -0.26, Rsq = 0.068, p = 0.021), using regressionequation it was revealed that every 1 unit increased of neopterin concentrations produce 1.42 decrease of e-GFR. Using ROCcurve, neopterin was accurately detect reduced kidney function defined as e-GFR of 60 ml/mnt or less (AUC = 0.88; 95%CI0.74 to 1.00; SE = 0.07; p = 0.02). Using 7.46 ng/ml as cut-off value for normal neopterin concentrations, it was showed thatsensitivity and specificity were 100% and 72% to detect the presence of reduced kidney function, consecutively. Neopterin maybe used as a novel biomarker for reduced kidney function, for its role in the pathogenesis of cardiorenal syndrome in generalpopulation.
