per 100,000 population (95% UI)
SDI: social-demographic index; UI: uncertainty interval; ASIR: age-standardized incidence rate; ASPR: age- standardized prevalence rate; ASMR: age- standardized mortality rate; DALYs: disability-adjusted life years; ASDR: age-standardized disability-adjusted life year rate; EAPC: estimated annual percentage change; CI: confidence interval.
According to the analysis of the trends of ASR ( Table 1 ), global ASIR (estimated annual percentage change (EAPC) =0.69, 95% confidence interval (CI) = 0.67–0.72), ASPR (EAPC = 0.31, 95% CI = 0.30–0.32), ASMR (EAPC = 0.73, 95% CI = 0.61–0.86), and ASDR (EAPC = 0.45, 95% CI = 0.34–0.56) illustrated an increasing trend from 1990 to 2019. Within five SDI quantiles, the middle SDI region displayed the highest absolute EAPCs for ASIR (EAPC = 1.14, 95% CI = 1.03–1.25) and ASPR (EAPC = 0.43, 95% CI = 0.40–0.47). The high SDI region exhibited the highest absolute EAPCs for ASMR (EAPC = 1.13, 95% CI = 0.82–1.45) and ASDR (EAPC = 0.78, 95% CI = 0.52–1.05), indicating the most rapid increase in burden. To assess the trends in the ASR over time from 1990 to 2019, Joinpoint analysis was used ( supplemental Table S1 and Figure S1 ). The AAPCs for ASIR, ASPR, ASMR, and ASDR were consistent with the findings from EAPCs. The ASIR and ASPR of females were consistently higher than males, while ASMR and ASDR of males were lower than those of females from 1990 to 2019. A significant temporal turning point was found in the APC for ASMR globally in 2014. From 1990 to 2014, the global ASMR gradually increased, but after this turning point, the ASMR began to decline (−0.39, 95% CI = −0.58 to −0.20, p < 0.001).
From 1990 to 2019, there was a consistent increase in CKD incident and prevalent cases across all age groups ( supplemental Figure S2A-B ). In 2019, the highest number of incident cases was observed in the age group of 65 and older (10,479,450, 95% UI = 7,587,790–13,721,140), surpassing the incident cases in both the age groups of less than 40 years (1,702,782 95% UI = 1,084,820–2,450,023) and 40–64 years (6,804,674, 95% UI = 4,789,427–9,106,637). As for prevalent cases from 1990 to 2019, the age group of 40-64 consistently remained higher compared to the other two age groups in all periods, reaching 273,676,189 (95% UI = 220,227,928–335,989,767) in 2019.
From 1990 to 2019, the global deaths and DALYs of CKD exhibited consistent upward trajectories across all age groups ( supplemental Figure S2C-D ). The highest number of CKD-related deaths was observed in the age group of 65 years and older, while the age group of 40-64 exhibited the highest DALYs from 1990 to 2019. Notably, the 40–64 age group consistently had higher DALYs compared to both the younger than 40 years and older than 65 years age groups, reaching 16,463,816 (95% UI = 14,658,979–18,775,233) in 2019 globally.
In the age-period-cohort analysis of CKD incidence among the global population from 1990 to 2019, a unimodal pattern was observed in age-specific incidence rate ( Figure 2(A) ). Between the ages of 0 and 84, the incidence rate of CKD gradually increased with age. However, beyond this age range, the incidence rate began to decline as individuals continued to age. In contrast to the unimodal pattern of incidence rate, the global CKD mortality rate demonstrated a consistent upward trend with increasing age ( Figure 2(D) ).
Age-period-cohort analysis of incidence (A–C) and mortality (D–F) of CKD in the globe, 1990–2019. Longitudinal age curves of incidence rate (A) and mortality rate (D). Period effects are displayed by the relative risk of incidence rate ratio (B) and mortality rate ratio (E) by comparing age-specific rates between 1990–1994 (the reference period) and 2015–2019. Cohort effects are determined by comparing the relative risk of incidence rate ratio (C) and mortality rate ratio (F) between the 1890 cohort and the 2019 cohort, with the 1985 cohort as the reference point. The dots and shaded areas represent the rate or rate ratio and their corresponding 95% CIs. CKD: chronic kidney disease; SDI: sociodemographic index; CIs: confidence intervals.
Regarding the period effect, the incidence rate ratio of CKD consistently increased globally from 1990 to 2019 ( Figure 2(B) ). In contrast, the global mortality rate ratio exhibited a complex trend, with an initial decrease followed by an increase, reaching 1.02 (95% CI = 1.00–1.03) in the years 2000 to 2004, and subsequently showing a decline ( Figure 2(E) ). The incidence rate ratio of CKD showed a rising trend across birth cohorts globally ( Figure 2(C) ). The mortality rate ratio for cohorts born after 1890 increased with each successive birth cohort until it reached 1.16 (95% CI = 1.10–1.22) for the 1955 to 1964 cohort, after which it began to steadily decline ( Figure 2(F) ).
The contributions of risk factors to deaths and DALYs of CKD are displayed in Figure 3 . Globally, high systolic blood pressure (Deaths, 61.6%; DALYs, 51.8%) was the most common contributing factor to deaths and DALYs of CKD globally, followed by high fasting plasma glucose (Deaths, 34.2%; DALYs, 31.5%) and high body-mass index (BMI) (Deaths, 27.8%; DALYs, 27.2%). In 2019, compared to other SDI regions, diet high in sodium contributed more significantly to deaths (8.1%) and DALYs (8.7%) of CKD in the high-middle SDI region, while low temperature had a greater impact on deaths (8.9%) and DALYs (6.3%) of CKD in the high SDI region.

A decomposition analysis of CKD incident cases was conducted globally, across five SDI regions, and within six WHO regions to investigate the impact of aging, population growth, and epidemiologic change from 1990 to 2019. On a global scale, population growth was the primary driver, contributing to 41.31% of the increased incident cases between 1990 and 2019 ( Figure 4 and supplemental Table S2 ).
Changes in the incident cases of CKD according to the three causes from 1990 to 2019 at the global level and by SDI quintile and WHO regions. The black dot represents the overall value of incidence change contributed from all causes. CKD: chronic kidney disease; SDI: sociodemographic index; WHO: World Health Organization. Specific data is presented in supplemental Table S2 .
As shown in Figure 5 and supplemental Table S3 , population growth was also the primary driver of the global increase in DALYs, contributing 63.20% to the rise in DALYs from 1990 to 2019. However, in the high SDI region (38.13%), Western Pacific Region (63.79%), and European Region (53.91%), aging was the predominant driver. Conversely, in the low SDI region (−2.20%) and African Region (−2.60%), aging was a negative driver for DALYs. To further analyze the driving forces of DALYs between 1990 and 2019 by different etiologies, epidemiological changes were decomposed into five detailed causes of CKD. Globally, T2DM was the most significant driver among the five diseases, accounting for 5.02%, followed closely by hypertension at 3.14%. The relative contribution of T2DM to DALYs varied across different SDI regions, being higher in high SDI (11.69%), middle SDI (2.94%), and low-middle SDI regions (2.88%). In comparison, T2DM was a negative driver in the low SDI region (−0.68%).
Changes in DALYs of CKD according to seven causes from 1990 to 2019 at the global level and by SDI quintile and WHO regions. The black dot represents the overall value of DALYs change contributed from all causes. DALYs: disability-adjusted life years; CKD: chronic kidney disease; SDI: sociodemographic index; WHO: World Health Organization; T1DM: type 1 diabetes mellitus; T2DM: type 2 diabetes mellitus; GN: glomerulonephritis; HP: hypertension. Specific data is presented in supplemental Table S3 .
To investigate changing trends in CKD burden across various territories, a frontier analysis of ASDR spanning 204 countries and regions worldwide was conducted from 1990 to 2019. This analysis, which uses ASDR as a key metric for understanding the impact of CKD, delineates countries and regions along a frontier line based on their respective SDI levels ( Figure 6(A) ). The top five countries with the greatest effective difference from the frontier, ranging from 1816.76 to 2033.74 ( Figure 6(B) and supplemental Table S4 ), included Micronesia (Federated States of), Nicaragua, Mauritius, Palau, and Nauru. These nations exhibited a disproportionately higher ASDR compared to countries with similar sociodemographic resources. Conversely, the top five countries with the lowest ASDR within their development spectrum, with effective differences ranging from 0.00 to 42.51 included Somalia, Finland, Iceland, San Marino, and Belarus.
(A) Frontier analysis of CKD based on SDI and ASDR from 1990 to 2019. The color scale represents the years from 1990, depicted in black, to 2019, shown in blue. The frontier is delineated in a solid black color. (B) Frontier analysis based on SDI and CKD ASDR in 2019. The frontier line is black; countries and territories are represented as dots. The top 15 countries with the most considerable effective difference of ASDR from the frontier line are marked in black words; examples of the countries with low SDI (<0.5) and low effective difference are labeled in blue (e.g., Somalia, Niger, Burundi, Papua New Gui). Examples of countries and territories with high SDI (>0.85) and relatively high effective distance for their level of development are labeled in red (e.g., United Arab Emirates, Taiwan (Province of China), United States of America, Kuwait, Singapore). Red dots indicate an increase in ASDR of CKD from 1990 to 2019; blue dots indicate a decrease in ASDR of CKD between 1990 and 2019. CKD: chronic kidney disease; SDI: sociodemographic index; ASDR: age-standardized disability-adjusted life year rate. Specific data is presented in supplemental Table S4 .
The BAPC model was employed to predict the evolving global trends in the incidence of CKD from 2020 to 2030 ( Figure 7 and supplemental Table S5 ). The global incidence rate per 100,000 population is expected to increase from 234.72 (95% CI = 135.40–586.10) in 2020 to 246.36 (95% CI = 0.93–2973.94) in 2030. The global incident cases will also increase from 19,627,543 (95% CI = 19,332,649–19,922,437) in 2020 to 26,346,589 (95% CI = 22,303,728–30,389,451) in 2030. This trend is consistent across different genders and SDI. Subsequently, based on mortality rate and deaths from 1990 to 2019, predictions were made for the global death trends of CKD from 2020 to 2030 ( supplemental Figure S3 and Table S6 ). By 2030, the global mortality rate per 100,000 population will decrease from 18.45 (95% CI = 1.23–543.11) in 2020 to 17.41 (95% CI = 0.00–5203.99) in 2030. Meanwhile, the global deaths were expected to increase from 1,483,812 (95% CI = 1,452,296–1,515,327) in 2020 to 1,924,241 (95% CI = 1,541,145–2,307,336) in 2030.
The trends of incident cases and ASIR in CKD in the globe and five SDI regions by sex, 1990–2030. ASIR: age-standardized incidence rate; CKD: chronic kidney disease; SDI: sociodemographic index; ASR: age-standardized rate. Specific data is presented in supplemental Table S5 .
In the predicted year 2030, the global incidence rate per 100,000 population is expected to be higher in females (251.78, 95% CI = 213.35–290.21) than in males (239.44, 95% CI = 202.48–276.41), with the number of incident cases also higher in females (14,330,860, 95% CI = 12,143,305–16,518,416) compared to males (12,015,729, 95% CI = 10,160,423–13,871,035). However, the mortality rate per 100,000 population is anticipated to be higher in males (20.82, 95% CI = 16.90–24.74) than in females (15.58, 95% CI = 12.30–18.85), with the number of deaths also expected to be greater in males (991,441, 95% CI = 804,591–1,178,290) than in females (932,800, 95% CI = 736,554–1,129,046).
While previous studies have utilized GBD data to explore the epidemiology of CKD, many were either descriptive or focused on specific aspects of the disease ( supplemental Table S7 ). For instance, Hu et al. concentrated on glomerulonephritis-induced CKD, emphasizing its significant burden in low SDI regions [ 20 ]. Similarly, Qing et al. and Feng et al. mapped the global burden of CKD using GBD 2019 data but did not investigate the potential drivers of CKD burden growth or predict future trends [ 21 , 22 ]. In contrast, our study provides more comprehensive analysis covering 204 countries and territories, offering a global perspective on CKD’s burden. We employed a variety of statistical methods, including decomposition analysis, frontier analysis, and BAPC modeling. These approaches allowed us to identify the primary drivers of CKD burdens, assess the efficiency of CKD management in relation to sociodemographic development, and predict future trends in CKD incidence and mortality. From 1990 to 2019, there was a notable rise in the burden of CKD, evidenced by its increased incidence, prevalence, mortality, and DALYs. On a global scale, in 2019, there were over 18 million new cases of CKD, reflecting a 69% increase, with 697 million prevalent cases, marking a 31% rise. Additionally, CKD accounted for nearly 1.4 million deaths, signifying a 73% surge, and resulted in 41 million years of healthy life lost, representing a 45% uptick. The BAPC model predicted a consistent increase of incidence and death from 2020 to 2030, reinforcing the persistent need for effective CKD management on a global scale.
In 2019, high systolic blood pressure was identified as a major risk factor of deaths and DALYs attributed to CKD globally. This finding is consistent with previous prospective observational studies that demonstrated a strong association between elevated blood pressure and the risk of CKD and end-stage renal disease (ESRD) [ 23 , 24 ]. Additionally, decomposition analysis highlighted hypertension as a key contributor to the global increase in CKD-related DALYs. These findings emphasize the critical importance of blood pressure management in the prevention and treatment of CKD. Hypertension and CKD often coexist, with poor blood pressure control significantly elevating the risk of developing cardiovascular and cerebrovascular complications [ 25 , 26 ]. The KDIGO guidelines recommend intensified antihypertensive therapy for CKD patients, targeting blood pressure control at 120/80 mmHg [ 27 ], while the European Renal Association advocated the use of ambulatory blood pressure monitoring with a target of 130/80 mmHg in patients on chronic dialysis [ 28 ]. Although intensified blood pressure control has not been conclusively shown to improve renal function, it reduces the incidence of cardiovascular complications [ 26 , 29 ]. Public health policies should prioritize early detection and management of hypertension among CKD patients, incorporating regular blood pressure monitoring and individualized antihypertensive therapy. Furthermore, public health initiatives should encourage lifestyle interventions, such as sodium reduction and fluid management. Given the challenges with patient compliance, especially concerning sodium intake, educating CKD patients to adopt and maintain these lifestyle changes is necessary [ 28 ]. Effective management of hypertension through a combination of pharmacological and non-pharmacological strategies can significantly reduce the burden of CKD and improve patient outcomes.
High fasting plasma glucose emerged as another significant risk factor contributing to the global burden of CKD in 2019. Decomposition analysis further identified T2DM as the primary driver of the increasing burden from 1990 to 2019. According to the International Diabetes Federation data in 2021, the global adult population with diabetes has reached 537 million and is expected to continue rising [ 30 ]. In the United States, nearly one-fourth of healthcare costs were related to T2DM, with a significant portion of these expenses attributable to T2DM-related CKD [ 31 ]. These results indicated that the burden of T2DM and T2DM-related CKD has been increasing year by year, leading to significant personal and social burdens. Public health policies for T2DM patients should emphasize early detection and glycemic control to prevent the development of CKD. Regular kidney function screening and provision of renal protective treatments, such as ACE inhibitors and SGLT2 inhibitors, could reduce CKD incidence [ 32 ]. Diabetic nephropathy (DN) is a complication of diabetic microvascular disease and has become one of the leading causes of ESRD. To prevent the progression of DN and the subsequent cardiovascular morbidity and mortality, it is crucial to implement personalized treatment, including strict blood glucose control, blood pressure management through RAAS inhibitors, aspirin, and lipid-lowering drugs [ 33 ]. Our study also found that in the low SDI region, T2DM was a negative driver of the increase in CKD burden from 1990 to 2019. It is necessary to cautiously interpret this result, as data collection and T2DM diagnosis in the low SDI region may be inadequate. Additionally, due to a lack of medical resources, T2DM patients may die prematurely from other infectious diseases before progressing to CKD, masking T2DM’s contribution to CKD burden [ 34 ]. Therefore, when formulating CKD-related health policies in the low SDI region, it is important to consider data quality and the most urgent health challenges faced by the local population.
From 1990 to 2019, ASIR and ASPR of CKD continued to rise for both males and females, while the ASDR and ASMR have shown a declining trend. Notably, the ASIR has consistently been higher in females. In contrast, males had higher ASDR and ASMR, indicating their worse outcomes. These gender differences were also found in the results by the BAPC model predictions, which indicated a higher incidence rate and incident cases of CKD in females, while mortality rates and deaths were higher in males. Previous epidemiological studies have also shown that CKD prevalence was generally higher in females, but kidney function declined faster in males [ 35 , 36 ]. The underlying reasons for this epidemiological difference between genders in CKD remain largely unexplored. Potential factors include physiological and lifestyle differences, such as longer life expectancy in females, the impact of pregnancy and estrogen, the detrimental effect of testosterone on male renal function, and unhealthy lifestyle choices among males [ 37 ]. It is noteworthy that many studies have revealed that in some countries, there are more male CKD patients undergoing RRT than females [ 38 ]. These data suggested, on the one hand, that CKD progresses more rapidly in males, and on the other hand, it indicated that females may tend to opt for conservative treatment modalities. Data from deceased kidney transplantation in the United States indicated that both the absolute number and transplantation rate of females were lower than those of males [ 39 ]. The difference in RRT between genders needs to be interpreted cautiously, and it cannot be directly concluded that there was unfair CKD management between males and females because most of this data originated from the United States and lacked high-quality research reports from other regions. Given the epidemiological differences in CKD between genders, gender-specific preventive, diagnosis, and management measures for CKD are crucial. For females, early detection and prevention are crucial, with an emphasis on educating them about CKD risks and encouraging regular screenings to reduce higher incidence rates. In contrast, male-focused strategies should prioritize managing complications, particularly cardiovascular issues, and promoting lifestyle interventions to address the faster disease progression and higher mortality rates. Additionally, policies should ensure equitable access to RRT and consider gender disparities in kidney transplantation.
In 2019, the highest number of incidence cases was seen in individuals aged 65 and older, while this age group consistently displayed the highest CKD-related mortality. The Age-Period-Cohort analysis of CKD showed that the mortality rate of CKD consistently rose with age. Decomposition analysis identified aging as the primary driver of the increasing burden in the high SDI region. According to the results from the US Renal Data System, the prevalence of CKD among individuals aged 65 and older was 33.2% in 2020, compared to 9% among younger adults [ 40 ]. Additionally, with the global increase in life expectancy, it is projected that by 2050, people aged 65 and older will make up more than 16% of the global population, with about two-thirds of those over 60 years old living in low-middle income countries [ 41 ]. This poses significant challenges for the formulation of public health policies in these countries. There are several potential reasons why older adults are more susceptible to CKD, including the loss of functional nephrons and the common presence of chronic conditions such as cardiovascular diseases and atherosclerosis [ 42 ]. Early vascular aging, characterized by accelerated arterial stiffness and endothelial dysfunction, plays a critical role in CKD pathogenesis among the elderly [ 43 ]. Early vascular aging not only contributes to the progression of CKD but also exacerbates cardiovascular complications, further increasing mortality risk in this population. To enhance CKD management in the elderly, public health policies should consider adopting age-specific eGFR thresholds and biomarkers to improve diagnosis and stratification. Incorporating routine assessments of arterial stiffness and endothelial function into CKD screening could also improve risk stratification and prevent cardiovascular complications. Finally, comprehensive pharmacological treatments, including anti-aging drugs and integrated antihypertensive treatments for arterial stiffness, are essential to further reducing mortality and improving outcomes in the elderly population [ 44 ]. In countries where CKD medications are unaffordable, dietary and behavioral therapies like calorie restriction, regular exercise, and a protein-restricted diet can promote healthy aging and reduce CKD progression [ 45 , 46 ].
The epidemiological features of CKD vary globally, with the United States having a 14% prevalence, driven by factors like T2DM, hypertension, and obesity [ 47 , 48 ]. In East Asia, CKD also poses a significant health challenge, with an estimated prevalence of 28.7% [ 49 ]. Besides diabetes and high blood pressure, major contributors to CKD in Eastern Asia include exposure to renal toxic substances and high-salt diets [ 50–52 ]. The SDI, covering per capita income, education levels, and fertility rates, is important for understanding the epidemiological characteristics of CKD globally. Overall, as SDI increased, ASIR rose, while ASMR and ASDR decreased from 1990 to 2019. This phenomenon has complex reasons, including disparities in healthcare funding, diagnostic criteria, and data entry quality [ 53 ]. Decomposition analysis revealed differences in CKD burden increases among regions with different SDI levels. In high, high-middle, and middle SDI regions, aging is the primary driver of CKD incidence increase, whereas in low-middle and low SDI regions, population growth is the main factor. Regarding the increase in CKD-related DALYs, besides aging being the primary driver in high SDI regions, population growth predominantly drives this increase in other SDI regions, particularly in low SDI regions (109.32%). Considering these findings, attention to CKD in elderly populations is warranted in high SDI regions, along with encouraging optimized fertility rates [ 2 ]. Globally, T2DM and hypertension play the most significant role in increasing CKD-related DALYs in high SDI regions. Therefore, emphasis should be placed on managing these comorbidities and promoting healthy lifestyle habits in these regions [ 54 ]. In contrast, countries with lower SDI levels exhibit lower social development, making it challenging to meet the healthcare needs of CKD. The intervention measures should prioritize disease care, treatment management, and improvement of environmental sanitation conditions [ 55 ]. Frontier analysis assessed the burden of CKD in different countries and regions, identifying areas for improvement based on SDI evaluation. Our analysis indicated that some high SDI countries exhibit higher disease burdens, such as the United Arab Emirates, Qatar, and Guam, necessitating targeted healthcare policies to ensure appropriate CKD management. Conversely, high-SDI countries like Switzerland, Norway, and Monaco showed minimal disparities between frontier DALYs and ASDR, suggesting progress in CKD management and efficient utilization of healthcare resources. These interplays between socio-economic development, healthcare accessibility, and CKD burden underscored the demand for customized healthcare strategies in regions of varying developmental stages to address the evolving burden of CKD.
Our study has several limitations. First, the definition of CKD in GBD relies on a single measurement of eGFR and ACR, which allows for broader and more inclusive estimates of CKD prevalence, making it useful for capturing a wide range of cases globally. However, this approach may include individuals with temporary or reversible kidney issues, as it does not meet the KDIGO criteria requiring abnormalities to persist for over three months. Additionally, the GBD definition does not consider other kidney damage markers beyond ACR, which are often unreported in the epidemiological studies that inform disease prevalence estimates. Second, variations in data quality and regional registration systems within the GBD dataset may introduce biases and affect the precision of our results. While the GBD study provides a comprehensive and standardized approach to estimating risk factor exposure and attributable burdens, it is based on aggregated data, limiting the application of traditional methods for controlling confounding factors. Third, the uncertainty inherent in the BAPC model can result in wider confidence intervals. This is due to the model’s reliance on past trends, which may be increasingly affected by data sparsity and variability over longer time horizons. Additionally, unanticipated health events, such as the emergence of Corona Virus Disease 2019 and other infectious diseases, can disrupt healthcare systems and population health trends, impacting the accuracy of our predictions.
In conclusion, this study examined the epidemiological trends of CKD from 1990 to 2019 and projected them through 2030. The findings underscore the escalating global burden of CKD, driven by age, SDI, lifestyle changes, and gender. The Age-Period-Cohort analysis highlights the importance of age-specific preventive strategies. Effective management of blood pressure and blood glucose is essential, particularly in high SDI regions. Public health policies should prioritize early detection and the integration of CKD prevention into broader health initiatives, while addressing regional and demographic disparities to mitigate CKD’s future impact and improve global health outcomes.

Chronic kidney disease (CKD), as defined by a reduction in the estimated glomerular filtration rate (GFR), is increasing in the United States, 1 in part because of the greater prevalence of obesity and hypertension 2,3 but in greater part because of improved longevity. Because GFR declines 1% per year for every year of life after the third decade, living longer means that it is possible to ...
Introduction. Chronic kidney disease (CKD) is defined as abnormal kidney function or structure present for greater than three months, with subsequent implications for health. 1. CKD is a common condition estimated to affect about nine to thirteen per cent of the adult population worldwide. 2.
Chronic kidney disease (CKD) is when the kidneys have become damaged over time (for at least 3 months) and have a hard time doing all their important jobs. CKD also increases the risk of other health problems like heart disease and stroke. Developing CKD is usually a very slow process with very few symptoms at first.
Chronic kidney disease (CKD) describes abnormal kidney function or structure. ... However, CKD is often unrecognised or diagnosed at an advanced stage. Late presentation of people with kidney failure increases morbidity, mortality and associated healthcare costs. ... NICE Clinical Guideline 182: Chronic kidney disease in adults: assessment and ...
The definition and classification of chronic kidney disease (CKD) guidelines were introduced by the National Kidney Foundation (NKF) Kidney Disease Outcomes Quality Initiative (KDOQI) in 2002, and were subsequently adopted with minor modifications by the international guideline group Kidney Disease Improving Global Outcomes (KDIGO) in 2004 [1-3].
The definition and classification of chronic kidney disease (CKD) have evolved over time, but current international guidelines define this condition as decreased kidney function shown by glomerular filtration rate (GFR) of less than 60 mL/min per 1·73 m2, or markers of kidney damage, or both, of at least 3 months duration, regardless of the underlying cause. Diabetes and hypertension are the ...
Chronic kidney disease (CKD) is a serious and common disease, and it eventuates in multiple complications, including premature mortality and end-stage kidney disease (ESKD). 1-3 An estimated 1 in 7 to 10 adults worldwide have CKD, with only approximately 10% surviving to ESKD and only half of survivors receiving dialysis or a kidney transplant ...
Chronic kidney disease (CKD) is a very prevalent and insidious disease, particularly with initially poorly manifested symptoms that progressively culminate in the manifestation of an advanced stage of the condition. The gradual impairment of kidney function, particularly decreased filtration capacity, results in the retention of uremic toxins and affects numerous molecular mechanisms within ...
Chronic kidney disease (CKD) is a serious and common disease, and it eventuates in multiple complications, including premature mortality and end-stage kidney disease (ESKD). 1,2,3 An estimated 1 in 7 to 10 adults worldwide have CKD, with only approximately 10% surviving to ESKD and only half of survivors receiving dialysis or a kidney ...
Acute kidney injury (AKI) and chronic kidney disease (CKD) are increasingly recognized as interconnected conditions with overlapping pathophysiological mechanisms. This review examines the transition from AKI to CKD, focusing on the molecular mechanisms, animal models, and biomarkers essential for understanding and managing this progression.
Patients with preexisting chronic kidney disease were excluded. Exposure Glomerular filtration rate was estimated from serum creatinine values using the updated 2022 Chronic Kidney Disease Epidemiology Collaboration formula, and eGFR greater than 60 mL/min/1.73 m 2 was regarded as normal. Exposure was defined based on the association between ...
Chronic kidney disease (CKD) is commonly associated with disorders of mineral and bone metabolism, manifested by either one or a combination of the following three components: Abnormalities of calcium, phosphorus, parathyroid hormone (PTH), fibroblast growth factor 23 (FGF23), and vitamin D metabolism.
IgG subclasses are named in order of natural abundance, and an elevated IgG1 level is commonly seen in patients with autoimmune disease, infection, or liver disease. 2,4 A markedly elevated serum ...
The company has approved medicines that treat the underlying causes of multiple chronic, life-shortening genetic diseases — cystic fibrosis, sickle cell disease and transfusion-dependent beta thalassemia — and continues to advance clinical and research programs in these diseases. Vertex also has a robust clinical pipeline of investigational ...
The interplay between metabolic disorders and chronic kidney disease (CKD) has been well-documented. However, the connection between CKD and atherogenic index of plasma (AIP) remains understudied. This research delves into the correlation between these two factors, aiming to shed new light on their potential association. The relationship between AIP and CKD was evaluated using a weighted ...

The epidemiology and management of patients with CKD , as well as clinical presentation and evaluation of CKD in children are discussed elsewhere: …
Introduction. Chronic kidney disease (CKD) is a leading cause of global mortality among non-communicable diseases, characterized by a sustained decline in glomerular function and elevated levels of albuminuria [1,2].According to the international guidelines, CKD is defined by the presence of markers of kidney damage or a glomerular filtration rate (GFR) of less than 60 mL/min per 1.73 m 2 for ...
