    ABSTRACT: CKD is a national public health problem that afflicts persons of all segments of society. Although racial/ethnic disparities in advanced CKD including dialysis-dependent populations have been well established, the finding of differences in CKD incidence, prevalence, and progression across different socioeconomic groups and racial and ethnic strata has only recently started to receive significant attention. Socioeconomics may exert both interdependent and independent effects on CKD and its complications and may confound racial and ethnic disparities. Socioeconomic constellations influence not only access to quality care for CKD risk factors and CKD treatment but may mediate many of the cultural and environmental determinants of health that are becoming more widely recognized as affecting complex medical disorders. In this article, we have reviewed the available literature pertaining to the role of socioeconomic status and economic factors in both non-dialysis-dependent CKD and ESRD. Advancing our understanding of the role of socioeconomic factors in patients with or at risk for CKD can lead to improved strategies for disease prevention and management.

    ABSTRACT: Worldwide, an estimated 200 million people have chronic kidney disease (CKD). In the United States, African Americans (AAs) have a four-fold excess risk of CKD compared to non-Hispanic white people and globally, people in the low-to-middle income countries of Asia and Sub-Saharan Africa have the highest rates of CKD. Annually, more than 500,000 individuals develop end-stage renal disease (or CKD stage 5) in Sub-Saharan Africa alone and the vast majority of these patients suffer premature mortality. The health care costs and economic burden of CKD are huge and not sustainable even in advanced Western countries. A recent discovery on the role of Apolipoprotein 1 (APOL1) G1 and G2 renal risk variants in AAs has a huge potential to unravel the etiology of CKD in both AA and other black populations. Under the National Institutes of Health (NIH)-sponsored Human Heredity and Health in Africa (H3Africa) initiative, a large prospective genetic study of CKD is being conducted in 8000 participants in four African countries (Ethiopia, Ghana, Kenya, and Nigeria; for a total population of 320 million). This and other basic research studies in the United States could potentially shed great insight into the genetics and biologic mechanisms involved in the excess predilection of Africans and AAs to CKD.

    ABSTRACT: Chronic kidney disease (CKD) is a major public health problem. However, few studies have examined the significance of serum bilirubin as a risk factor for the development of CKD in the general Japanese population. The subjects comprised 413 men (mean age: 79±9 years; (range, 60-100 years) and 637 women (mean age: 81±8 years; range, 60-106 years) who visited the medical department of Seiyo Municipal Nomura Hospital. We examined the relationship between increased serum bilirubin and renal function that was evaluated by estimated glomerular filtration rate (eGFR) using CKD-EPI equations modified by a Japanese coefficient. Stepwise multiple regression analysis with eGFR as the objective variable, and adjusted risk factors as the explanatory variables, showed that serum bilirubin (β = 0.11, P<0.001) was significantly and independently associated with eGFR, in addition to gender, age, prevalence of antihypertensive medication, triglycerides, prevalence of antidiabetic medication, and serum uric acid. Compared with stages 1+2 (eGFR ≥60.0 ml/min/1.73 m2), mean multivariate-adjusted odds ratio {95% (confidence interval (CI)} for hypobilirubinemia (first quartile, <0.52 mg/dL) was 3.52 (range: 1.88-6.59). Next, to control potential confounding factors, data were further stratified by gender, age, medication (antihypertensive, antidyslipidemic, and antidiabetic agents), and prevalence of cardiovascular disease. The standardized coefficient for eGFR was significant in both groups, and there was no interaction between the groups. Our data demonstrated an independent positive association between serum bilirubin and eGFR in both genders. Low serum bilirubin level would be useful as a potential risk factor for renal function.
