Сhronic kidney disease (CKD) is the important public and medical problem in the world because of a large burden on health care systems. The prevalence of CKD and number of dialysis patients are increasing in the world. The prevalence and incidence of CKD depends on age, race, and gender of patients, region, and the presence of the CKD registry in a country. Diabetes mellitus (DM) and arterial hypertension (AH) are the most common causes of end stage renal disease (ESRD). It is projected that the number of dialysis patients will reach 5.5 million in 2030. Specific strategies and interventions should be urgently aimed at reducing in the burden of CKD by means of the prevention, detection and treatment of DM, AH, and early stages of CKD. One more strategy is the organization of own domestic manufacture of solutions for dialysis therapy.
chronic kidney disease, hemodialysis, peritoneal dialysis
The prevalence of chronic kidney disease (CKD) has been increased dramatically in the world for the past three decades (
CKD affects more than 10% of the world population (
The prevalence of CKD (stages 3–5 ranges) from 1.3% to 15.7% and 2.2% to 11.7% among men and women, respectively, depending on the country (
CKD, diabetes mellitus (DM) and cardiovascular diseases are major regional and global causes of death (
CKD is caused by DM, arterial hypertension (AH), obesity, aging, unhealthy diet and other known and unknown reasons (
The incidence and prevalence of DM increases in the world mainly due to the rise in obesity and other risk factors for type 2 diabetes (
The number of people receiving renal replacement therapy (RRT) was more than 2.5 million in 2010 and was projected to reach 5.439 million (3.899–7.640) in 2030 (
The aim of this paper is to generalize data on the prevalence and incidence of CKD, end-stage renal disease (ESRD), hemodialysis (HD) and peritoneal dialysis (PD) as well. Reliable data about the prevalence of NCD is essential for the elaboration of health policies for their prevention, treatment and control (
The 2012 KDIGO guidelines contain the advanced classification. CKD was defined as eGFR less than 60 mL/min per 1.73 m2 or the presence of albuminuria. CKD is classified into 5 stages depending on eGFR (
Stage | eGFR (mL/min/1.73 m2) |
---|---|
1 | >90 |
2 | 60–89 |
3 | 30–59 |
3a | 45–59 |
3b | 30–44 |
4 | 15–29 |
5 | <15 |
CKD induces the profound challenge for health care systems related to the consumption of significant social and financial recourses (
ERSD is a consequence of the CKD progress (
The issue of the connection between GFR and age is disputed as there is a natural decline in GFR in the elderly with aging. This controversial issue raises a question about what is normal aging and what is disease (
In 2017 there were 649.2–752.1 million people with CKD in the world. Thus, the prevalence of CKD was estimated as 9.1%. Patients with 1–2 stages of CKD accounted for 4.5–5.5%, 3 stage – 3.5–4.3%, 4 stage – 0.13–0.19%, 5 stage – 0.06–0.08%, dialysis patients – 0.037–0.044% and patients with kidney transplantation – 0.010–0.012% (
Asia is considered to be the region with the biggest ESRD population (
It is worthy of attention that the epidemiology of CKD and ESRD in South Asia had been not well defined by 2012, despite being one of the most populous region (
The prevalence of dialysis patients is increasing in China. For example, there were 33.2 persons per million people (p.m.p) in 1999, 51.7 p.m.p in 2008, 92.3 p.m.p in 2009, while the prevalence of CKD was in the range of 10.2–11.3% in 2012 in a cross-sectional survey of Chinese adults (
Similar situation was determined in a cross-sectional survey of Chinese rural residents in 2015–2017. The prevalence of CKD was in the range of 15.9–16.8% (16.4%). However, the division between stages was not analogous. The patients with 1 stage of CKD accounted for 10.6–11.4%, 2 stage for 2.9–3.3%, 3 stage – 1.1–1.4%, 4 stage – 0.3–0.5%, 5 stage – 0.3–0.5% (
The prevalence of CKD among urban diabetic patients is 48%, while its prevalence among rural diabetic patients was 35.5% (
Developed countries spend 2–3% of their annual health care budget to treat patients with ESRD, but their number is only 0.02–0.03% of the total population (
There are fluctuations in the prevalence of CKD between European populations. The results of the NATPOL 2011 survey demonstrated that the prevalence of CKD was estimated at 5.8% in Poland (95% confidence interval (95% CI) 4.6–7.2%). An eGFR less than 60 mL/min/1.73 m2 and albuminuria were revealed in 1.9% (95% CI 1.5–2.5%) and 4.5% (95% CI 3.4–5.9) of the studied population, respectively. AH and DM were more frequent in the patients with diagnosed CKD compared with those without CKD (67.8% versus 29.0% (P < 0.001) and 18.5% versus 4.5% (P < 0.001), respectively). DM and AH were, apart from increasing in age, the greatest risk factors of CKD (
The adjusted prevalence of CKD stages 1–5 was in the range of 3.30% to 3.33% in Norway, 9.0% to 10.6% in Spain, 16.5% to 18.1% in Germany, and 4.8% in the Netherlands (ages 20–74). Thus, the total prevalence of CKD in some European countries was lower compared to the prevalence in the world. The regional variations in CKD could be explained by the prevalence of DM, AH, and obesity in the general population and other factors. Among these factors are dietary habits, healthcare policies, gene factors, differences in the time period of a study. All estimations were performed considering the same definition of CKD stages 1–5: eGFR <60 ml/min per 1.73 m2 calculated by the CKD-Epidemiology Collaboration equation and/or ACR >30 mg/g (
One more report provided the following prevalence for Spain, Portugal and the Netherlands in 2014: 9.2%, 6.1–10% and 10.4%, respectively (
In the USA the prevalence of CKD increased from 10.0% in 1988–1994 to 13.1% in 1999–2004 (
Pakistan and India are the biggest and most populous countries in South Asia (
DKD is a complication of long poorly controlled diabetes (
In 2016 the exact incidence and prevalence of CKD or ESRD were not known in Sri Lanka, India, Bangladesh, Pakistan and Nepal as these countries did not have a country-wide registry or method for the continuous collection of such data. The prevalence of CKD ranged from 2.3 to 9.5% in Sri Lanka, India and Nepal. A very high prevalence of CKD was found in Pakistan and Bangladesh, 12.5% and 26%, respectively. It is worthy of mentioning that CKD definition included the following: eGFR <60 mL/min/1.73 m2 or albuminuria (
The incidence of ESRD related to DM increased two times from 1997 to 2006 in Iran (from 16% to 31%) (
According to Carreo et al. (2018), the number of women with predialysis CKD is larger compared to that of men that could be explained by the longer life expectation and overestimation of eGFR (Carreo et al. 2018). However, this issue is controversial and depends on region and age. For example, the prevalence of reduced eGFR and albuminuria were much higher in men at the age of 18–39 (3.0% versus (vs) 0.7% and 13.8% vs 12.9%) and 40–59 (1.5% vs 0.9% and 15.5% vs 14.5%), while that there was an opposite situation in men at the age of 60–69 (1.9% vs 2.3% and 14.9% vs 18.8%) and ≥70 (6.9% vs 10.5% and 18.6% vs 25.8%) (
Among the main causes of CKD are DM, AH, chronic pyelonephritis, chronic glomerulonephritis, autoimmune diseases, prolonged acute renal disease, etc. (
DM is the most common cause of ESRD in the whole world (
The second cause of CKD is AH. In 2010 there were 55% of deaths from high blood pressure (HBP) caused by cardiovascular diseases, CKD and DM in Central Asia, Eastern Europe, and sub-Saharan Africa (
Overall, AH is a cause of CKD in Eastern Asia, Eastern Europe, tropical Latin America, and Western sub-Saharian Africa, while DM is a cause in other regions (
According to
According to the World Health Organization (2020), obesity has increased nearly by 3 times since 1975. In 2016, there were more than 1.9 billion overweight adults at the age of 18 and older, including over 650 million were obese that accounted for 39% and 13% of the world’s population, respectively. However, obesity is preventable (World Health Organization). An increase in people with obesity is explained by changing lifestyles, especially a reduced physical activity (
It is important to note that causes of ESRD were unknown in 16–27% of adult patients in Sri Lanka, India, Bangladesh, Pakistan and Nepal. Among such unknown cases could be alternative or herbal drugs administration, occupational exposure to pesticides, contamination of water and food by heavy metals, and unrecognized effects of tropical infections (
RRT is recommended to patients at GFR less than 20 ml/min (
The incidence of all the RRT forms grows as well. For instance, the incidence of HD and PD annually increases by 6–7% and 8%, respectively (
In 2002 the prevalence of RRT was 79, 273, 405, 488, 636, 658, 918, 895–1081, 1097 p.m.p, respectively, in the Russian Federation, Estonia, Poland, Slovakia, Finland, the Netherlands, Germany, Spain (depending on region), Portugal (
HD penetration is much larger than PD worldwide. HD is more prevalent RRT modality in the world (
In 2016 all the forms of RRT were available in India, Pakistan, Sri Lanka, Bangladesh, and Nepal. Their penetration, however, is mainly limited to urban areas (
Up to 2013 data from Pakistan had suggested that about 30% of dialysis units did not have any water treatment facilities. In India and Pakistan the penetration of chronic PD was weak as less than 20% of all long-term dialysis patients were on PD. Cost and high infection rates interfered with increasing in the penetration of chronic PD. The Indian government had included the care for CKD in its 12th 5-year plan cycle and developed a framework for dialysis and transplantation. It was planned to set up dialysis centers across the country and manage by the private sector, however, the government was going to reimburse these centers costs at a predetermined rate (
In 2013 the RRT expenditures were less in India and Pakistan than in developed countries, however, they were out of the reach for most people. The monthly cost of the common prescriptions (2 HD procedures per week and 3 PD exchanges per day) was 609 and 585 US dollars, respectively. These expenditures were paid by most patients (
The nephrological care with HD is growing in Ukraine. There were 724–866 HD apparatuses in 2012. This number grew to 1164 in 2016 (
The presence of the CKD register indicates the CKD surveillance in a country and, thus, gives a real possibility to evaluate the number of people suffering from CKD and patients needing RRT (
The CKD Registry started to recruit all CKD patients in 2011 in Australia (
The availability of RRT is limited in many countries with a high burden of CKD (
This article summarizes the information on the epidemiology of CKD in some countries of the world. CKD is the important public and medical problem in the world because of a growing number of patients suffering from CKD and a large burden on health care systems. Providing CKD and ESRD care is a social, economic and medical challenge. On the one hand, revealing risk factors of the development of CKD is likely to reduce its prevalence, but on the other, an increased availability of RRT and the projected growth in DM, AH and cardiovascular diseases will enlarge the prevalence of CKD in the future. The review shows that it is necessary to develop strategies in order to prevent or reduce the burden of CKD and manage CKD and ESRD. Among the strategies are the prevention, detection and treatment of DM, AH, and early stages of CKD. One more strategy in each country is the organization of own manufacture of solutions for dialysis therapy in order to reduce their cost by the elimination of international delivery.
