Carga, acceso y disparidades en enfermedad renal
Kidney disease is a global public health problem that affects more than 750 million persons worldwide.1 The burden of kidney disease varies substantially across the world, as does its detection and treatment. Although the magnitude and impact of kidney disease is better defined in developed countries, emerging evidence suggests that developing countries have a similar or even greater kidney disease burden. In many settings, rates of kidney disease and the provision of its care are defined by socioeconomic, cultural, and political factors, leading to significant disparities in disease burden, even in developed countries.3 These disparities exist across the spectrum of kidney disease—from preventive efforts to curb development of acute kidney injury (AKI) or chronic kidney disease (CKD), to screening for kidney disease among persons at high risk, to access to subspecialty care and treatment of kidney failure with renal replacement therapy (RRT). World Kidney Day 2019 offers an opportunity to raise awareness of kidney disease and highlight disparities in its burden and current state of global capacity for prevention and management. In this editorial, we highlight these disparities and emphasize the role of public policies and organizational structures in addressing them. We outline opportunities to improve our understanding of disparities in kidney disease, the best ways for them to be addressed, and how to streamline efforts toward achieving kidney health equity across the globe.La enfermedad renal es un problema global de salud pública que afecta a más de 750 millones de personas alrededor de todo el mundo1. La carga de la enfermedad renal varía sustancialmente a lo largo del planeta, al igual que su detección y tratamiento. A pesar de que la magnitud y el impacto de la enfermedad renal está mejor definida en los países desarrollados, evidencia reciente sugiere que los países en desarrollo tienen una carga de la enfermedad similar o incluso mayor que los primeros2.En muchos escenarios, las tasas de enfermedad renal y la provisión de su cuidado están definidas por factores socioeconómicos, culturales y políticos, ocasionando disparidades significativas en la carga de la enfermedad, aún en países desarrollados3. Estas disparidades existen a lo largo de todo el espectro de la enfermedad renal – desde los esfuerzos preventivos para limitar el desarrollo de la lesión renal aguda (LRA) o de la enfermedad renal crónica (ERC), al tamizaje para enfermedad renal entre las personas con alto riesgo de desarrollarla, al acceso a cuidado y tratamiento subespecializado de la falla renal con terapia de reemplazo renal (TRR). El Día Mundial del Riñón 2019 ofrece una oportunidad para hacer conciencia de la enfermedad renal y resaltar las disparidades en su carga y el estado actual de la capacidad global para su prevención y manejo. En esta editorial, resaltamos estas disparidades y hacemos énfasis en el rol de las políticas públicas y las estructuras organizacionales en su atención. También destacamos las oportunidades de mejorar nuestro entendimiento de las disparidades en la enfermedad renal, la major formas de que éstas puedan ser reducidas, y como canalizar esfuerzos enfocados a alcanzar una salud renal con equidad a lo largo del planeta

Dietary acid load and chronic kidney disease among adults in the United States
Abstract
Background
Diet can markedly affect acid-base status and it significantly influences chronic kidney disease (CKD) and its progression. The relationship of dietary acid load (DAL) and CKD has not been assessed on a population level. We examined the association of estimated net acid excretion (NAEes) with CKD; and socio-demographic and clinical correlates of NAEes.
Methods
Among 12,293 U.S. adult participants aged >20 years in the National Health and Nutrition Examination Survey 1999–2004, we assessed dietary acid by estimating NAEes from nutrient intake and body surface area; kidney damage by albuminuria; and kidney dysfunction by eGFR < 60 ml/min/1.73m2 using the MDRD equation. We tested the association of NAEes with participant characteristics using median regression; while for albuminuria, eGFR, and stages of CKD we used logistic regression.
Results
Median regression results (β per quintile) indicated that adults aged 40–60 years (β [95% CI] = 3.1 [0.3–5.8]), poverty (β [95% CI] = 7.1 [4.01–10.22]), black race (β [95% CI] = 13.8 [10.8–16.8]), and male sex (β [95% CI] = 3.0 [0.7- 5.2]) were significantly associated with an increasing level of NAEes. Higher levels of NAEes compared with lower levels were associated with greater odds of albuminuria (OR [95% CI] = 1.57 [1.20–2.05]). We observed a trend toward greater NAEes being associated with higher risk of low eGFR, which persisted after adjustment for confounders.
Conclusion
Higher NAEes is associated with albuminuria and low eGFR, and socio-demographic risk factors for CKD are associated with higher levels of NAEes. DAL may be an important target for future interventions in populations at high risk for CKD.http://deepblue.lib.umich.edu/bitstream/2027.42/109474/1/12882_2014_Article_829.pd
Depressive symptoms, frailty, and adverse outcomes among kidney transplant recipients
Depressive symptoms and frailty are each independently associated with morbidity and mortality in kidney transplant (KT) recipients. We hypothesized that having both depressive symptoms and frailty would be synergistic and worse than the independent effect of each. In a multicenter cohort study of 773 KT recipients, we measured the Fried frailty phenotype and the modified 18â question Center for Epidemiologic Studiesâ Depression Scale (CESâ D). Using adjusted Poisson regression and survival analysis, we tested whether depressive symptoms (CESâ D score > 14) and frailty were associated with KT length of stay (LOS), deathâ censored graft failure (DCGF), and mortality. At KT admission, 10.0% of patients exhibited depressive symptoms, 16.3% were frail, and 3.6% had both. Recipients with depressive symptoms were more likely to be frail (aOR = 3.97, 95% CI: 2.28â 6.91, P < 0.001). Recipients with both depressive symptoms and frailty had a 1.88 times (95% CI: 1.70â 2.08, P < 0.001) longer LOS, 6.20â fold (95% CI:1.67â 22.95, P < 0.01) increased risk of DCGF, and 2.62â fold (95% CI:1.03â 6.70, P = 0.04) increased risk of mortality, compared to those who were nonfrail and without depressive symptoms. There was only evidence of synergistic effect of frailty and depressive symptoms on length of stay (P for interaction < 0.001). Interventions aimed at reducing preâ KT depressive symptoms and frailty should be explored for their impact on postâ KT outcomes.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146305/1/ctr13391_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146305/2/ctr13391.pd
Apolipoprotein L1, income and early kidney damage
BACKGROUND: The degree to which genetic or environmental factors are associated with early kidney damage among African Americans (AAs) is unknown. METHODS: Among 462 AAs in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study, we examined the cross-sectional association between apolipoprotein L1 (APOL1) risk variants and income with: 1) mildly reduced eGFR (<75 mL/min/1.73 m(2), creatinine-cystatin C equation) and 2) elevated urine albumin-to-creatinine ratio (ACR) (≥17 in men and ≥25 mg/g in women). High risk APOL1 status was defined by 2 copies of high-risk variants; low risk if 0 or 1 copy. Income groups were dichotomized as < 14,000/year. Logistic regression models were adjusted for age, sex, and % European ancestry. RESULTS: Overall, participants’ mean age was 47 years and 16% (n = 73) had high risk APOL1 status. Mean eGFR was 99 mL/min/1.73 m(2). Mildly reduced eGFR was prevalent among 11% (n = 51). The lowest income group had higher adjusted odds (aOR) of mildly reduced eGFR than the higher income group (aOR 1.8, 95% CI 1.2-2.7). High-risk APOL1 was not significantly associated with reduced eGFR (aOR 1.5, 95% CI 0.9-2.5). Among 301 participants with ACR data, 7% (n = 21) had elevated ACR. Compared to low-risk, persons with high-risk APOL1 had higher odds of elevated ACR (aOR 3.8, 95% CI 2.0-7.3). Income was not significantly associated with elevated ACR (aOR 1.8, 95% CI 0.7-4.5). There were no significant interactions between APOL1 and income. CONCLUSIONS: Both genetic and socioeconomic factors may be important determinants of early kidney damage among AAs.
