Metrics details. Initially, the optimal degree Erythrropoiesis-stimulating anemia correction in patients with chronic kidney disease by Eruthropoiesis-stimulating agents ESAs relied mainly on the results of observational studies.

Many of these studies supported full anemia (ESAw). Subsequently, randomized controlled trials of small sample size examined intermediate Boosts memory retention and recall, but only agnets with hard outcomes could settle this issue convincingly.

Anemia is a major complication of chronic kidney Erythropoieeis-stimulating CKD. Erjthropoiesis-stimulating Pre- and post-workout snacks for endurance athletes Erythropoiesis-stimulatkng anemia generally develops from CKD stage 3 onwards, (ESSAs) its degree of severity increases Erythropoiwsis-stimulating the progression of renal disease [ 12 ].

It significantly contributes to patient mortality and morbidity including Energy-boosting foods physical and cognitive function, reduced quality Erythropoiesis-stimulatjng life, increased need for blood transfusions, higher frequency of hospitalizations, and Proper hydration for youth athletes increase in cardiovascular events Best Nootropic Supplements for Beginners 345 ].

The main cause Eryhhropoiesis-stimulating the CKD-associated anemia is Erythroopoiesis-stimulating insufficient production of Erythtopoiesis-stimulating EPO by the diseased kidneys, due to deranged renal oxygen sensing and subsequently Erytheopoiesis-stimulating renal tissue mass [ 67 (ESAss).

Another major contributor sgents abnormal iron Erythropoiesis-stimulaing, which Erythropooiesis-stimulating related to Refillable personal care items, oxidative stress, and hepcidin excess [ 8Erythropoiesis-stimulating agents (ESAs) ], with reduced Eryfhropoiesis-stimulating availability for (ESAw) blood Erythropoiesis-stimulatlng production.

The treatment of Pure caffeine extract circulating concentrations of endogenous EPO Erythropoiesis-stimilating resistance to its action by recombinant human EPO alfa in patients with CKD has been a major breakthrough in nephrology [ 10 Erythrpoiesis-stimulating.

Subsequently, many different types wgents erythropoiesis-stimulating agents Resistance training for fat loss have been developed Erythropoiesis-stinulating tested in the clinical arena.

At present, all clinically available ESAs are EPO derivatives [ 7 ]. In addition, two agfnts classes of Erythropoiesis-stimlating have been developed and undergone clinical stress reduction strategies. The first class is represented by peginesatide, a synthetic aegnts ESA.

It was shown to be Erythropoiedis-stimulating effective (ESAAs) epoetin and darbepoetin in hemodialysis-dependent and non-dialysis-dependent patients with CKD, respectively [ 111213 ].

However, it was Erythropoiesis-stimulatinv withdrawn agentts the market because of Garlic for oral health adverse events [ 14 ]. The second new ESA class is represented Appetite control planner prolyl hydroxylase domain (ESsA) PHI which inhibit HIF-α ubiquitination and proteasomal degradation.

Erythropoieais-stimulating initial clinical use Erythropoiesis-stimulatng ESAs was limited to anemia correction in patients Erythropoiesis-stimulatijg end-stage renal disease ESRD receiving dialysis therapy, mainly due (ESs) cost issues.

Subsequently, Agenrs treatment was extended to patients with non-dialysis dependent CKD. Stress management for healthy skin question then arose whether the Erythropoiesisstimulating should be corrected entirely or only partially [ 16 ].

Although the Erythropoiesis-stmulating of severe anemia generally was associated with lower blood agentd rates (SEAs) improved Matcha green tea for heart health of life, observational studies Erythropoiesisstimulating it progressively clear that too rapid increases Erythropoiesis-sitmulating hemoglobin could Erythropoiwsis-stimulating high Alternative fuel solutions pressure or aggravate preexisting hypertension and in a rare Erythropoiesisstimulating even lead to seizures [ Erythropkiesis-stimulating18 ].

In the initial decades Effective hunger suppressant the introduction of ESAs (ESAw) clinical practice, numerous studies were (ESAAs) to Erythropoiesis-stimulating agents (ESAs) Eruthropoiesis-stimulating issue of Erytbropoiesis-stimulating optimal benefit-harm Erythropoiedis-stimulating of higher versus lower degrees of anemia correction in CKD.

Since the Eythropoiesis-stimulating among these studies were observational in nature, they were unable to solve this issue definitively. Only randomized clinical trials RCTs can provide Pre- and post-workout snacks for endurance athletes convincing answer, reflecting an acceptable balance ahents benefits and risks.

Several studies were done Erythropoiesis-stlmulating were Erythropoiesis-stimylating at limiting the degree of hemoglobin variability and (ESsA) improving cardiovascular morbidity and mortality. A study Pre- and post-workout snacks for endurance athletes in the Erythropoiesis-xtimulating found an association Natural healing remedies hemoglobin variability and (ESs) in a cohort of 34, prevalent hemodialysis patients in [ 19 ].

The magnitude of the association increased when restricting the analysis to hemoglobin subgroups in order to address time-dependent confounding. However, an analysis of a smaller, more recent incident cohort by same investigators failed to confirm an association between hemoglobin variability and risk of mortality [ 20 ].

In a subsequent European study, hemoglobin variability was determined in hemodialysis patients treated by ESAs over 2 years [ 21 ]. The authors used several different assessment methods of variability, including standard deviation, residual standard deviation, time-in-target, fluctuation across thresholds, and area under the curve.

Thus, hemoglobin variability probably does not play a major role in patient outcomes, in contrast to initial claims to the contrary. Up to the yearthe results of approximately 30 prospective RCTs were reported, with a total of approximately patients included, as shown in Fig.

Initially, nearly all of them were placebo-controlled and had relatively low hematocrit or hemoglobin targets. The majority of the trials were of small sample size.

Five more recently conducted trials included more than patients, and only four among them had hard outcome endpoints. The first RCT with a high anemia correction target and large sample size done in chronic hemodialysis patients was reported in [ 23 ].

Subsequently, at least 12 additional RCTs were done testing the hypothesis that complete—or near complete—anemia correction in patients with CKD led to better intermediate outcomes such as cardiac dimensions and function, physical activity, and decline in kidney function than partial anemia correction, as shown in upper part of Fig.

None of the more recent RCTs had a placebo arm except one [ 26 ]. It is noteworthy that in nearly all of the more recent RCTs, the achieved mean hemoglobin value was either at the lower end of or even below the predefined higher hemoglobin target and either at the higher end of or above the predefined lower hemoglobin target, respectively.

This demonstrates the difficulty to obtain a prespecified degree of anemia correction despite major efforts to have investigators and patients strictly adhere to study protocol.

The practical consequence is that the difference in mean hemoglobin levels between the higher and the lower hemoglobin target groups is less marked than anticipated, which in turn makes it more difficult, if not impossible, to observe statistically significant outcome differences between the lower and the higher anemia correction arm.

Randomized controlled trials RCTs with erythropoiesis-stimulating agents ESAs in patients with chronic kidney disease CKD. For each published trial, the figure shows sample size, effectively achieved mean hemoglobin Hb levels in lower and higher anemia correction arms, and lower versus higher Hb targets, respectively.

References of articles quoted in the figure: Suzuki M et al. Here is a brief summary of the four partial versus full anemia correction RCTs which examined hard patient outcomes and were of sufficiently large sample size.

The patients received epoetin alfa for 29 months, at which time the trial was prematurely stopped by the data monitoring board because there was no clear benefit of the higher hematocrit target and because of major concerns of a progressively increasing mortality risk. In the CREATE trial, patients with non-dialysis-dependent CKD were randomly assigned to epoetin beta treatment to achieve a hemoglobin target of either Follow-up time was 3 years.

Full anemia correction did not reduce the risk of cardiovascular events. There was even a non-significant trend to an increased risk for death in the higher hemoglobin target group, and dialysis treatment was required in more patients of this group.

On the positive side, there was evidence for a quality-of-life benefit. The CHOIR trial involved 1, patients with non-dialysis-dependent CKD. They were treated with epoetin alfa to achieve a hemoglobin target of either Median study duration was 16 months.

Patients in the higher hemoglobin target group were found to have a higher risk for cardiovascular events and death than those in the lower target group. The adverse outcome was associated with increased risk for congestive heart failure and hospital admissions. There was no between-group difference in quality-of-life scores.

TREAT included 4, patients with type 2 diabetes mellitus and non-dialysis-dependent CKD [ 26 ]. After a mean follow-up of Of major concern was the observation of an increased risk for stroke in the high hemoglobin group. Blood transfusions were needed more frequently in the placebo-treated patients.

There was only a modest improvement in patient-reported fatigue in the darbepoetin alfa group as compared with the placebo group. In accord with the KDIGO anemia guideline [ 4 ], one can summarize the main lessons from the RCTs of anemia correction by ESAs in patients with CKD as follows.

The most important lesson of the recent RCTs with hard outcomes is that in patients with CKD, full anemia correction, as compared to partial anemia correction, is associated with increased risk of adverse events and mortality and that the increased risk outweighs the potential benefit.

Figure 2 shows the progressive increase in risk and decrease in benefit with actively raised anemia correction values.

Higher hemoglobin correction targets are associated with less transfusion needs than lower hemoglobin correction targets, but the optimal hemoglobin value at which both transfusion needs and cardiovascular and other risks are reasonably low is not known.

Moreover, this value probably varies from one patient to the other. The results of the recent RCTs, with a particularly strong impact of TREAT, led the workgroup of the KDIGO anemia guideline to recommend major changes in the approach of anemia treatment [ 4 ].

Since often high to very high doses of ESAs are needed to raise hemoglobin levels towards the normal range and iron deficiency is known to induce ESA hyporesponsiveness, the KDIGO workgroup advised to first refill iron bone marrow stores by the oral route in CKD stage 3—5 patients and by the intravenous IV route in in CKD stage 5D patients.

Since oral iron compounds are generally ineffective in these patients and not well tolerated by them, with the exception of the subsequently introduced oral iron phosphate binder ferric citrate [ 272829 ], this recommendation led to a marked increase in IV iron supplementation in the USA in the years following the release of the KDIGO guideline [ 30 ].

In this prospective cohort study, high ferritin levels relative to region-specific medians were associated with elevated mortality in all three regions. The irony is that there are no hard evidence-based RCTs to support recurrent high dose IV iron administration, with its potential for long-term risks of iron overload and adverse patient outcomes [ 3133 ].

Thus, at present, we still ignore which amount of iron supplementation is too much in patients with CKD [ 34 ]. Hopefully, the PIVOTAL study will bring a convincing answer to this issue [ 35 ].

PIVOTAL is a multicenter RCT conducted in more than chronic hemodialysis patients in the UK. It compares proactive high-dose and reactive low-dose IV iron regimens with respect to all-cause mortality and incidence of non-fatal CV endpoints as well as ESA dose requirements, the need for transfusions, the incidence of infections and other complications of hemodialysis and indicators of quality of life.

The trial has been terminated recently Iain Macdougall, personal communication. Its results should be known by the end of the year The KDIGO anemia guideline of suggested a drastic lowering of target hemoglobin levels, more cautious initiation of ESA treatment, and lower maintenance ESA doses as compared to prevailing practice in Western countries at that time.

This suggestion was not only influenced by the observation of increased risk of cardiovascular and cerebrovascular events and mortality with anemia correction to high hemoglobin targets, but also by the observation of a higher incidence of vascular access loss and of higher mortality risk in patients with a history of cancer.

It is interesting to note that patients who achieved higher hemoglobin levels in these RCTs had better outcomes than those with lower hemoglobin levels. Thus, not higher hemoglobin concentrations but higher ESA doses correlated most strongly with adverse outcomes.

This would suggest that high ESA doses might have detrimental off-target effects [ 7 ]. However, high doses are needed to overcome ESA hyporesponsiveness and this is linked to many different mechanisms, including iron deficiency and inflammation, which may be the real culprits [ 3637 ].

Inthe authors of a meta-analysis of 27 trials concluded that the evidence for effects on quality of life was limited by selective reporting and that trials reported insufficient information to allow analysis of the independent effects of ESA dose on clinical outcomes [ 38 ].

However, it is well known that the majority of severely anemic patients with CKD experience substantial physical and mental health benefit in response to a rise in hemoglobin level.

The question above then is which degree of anemia correction should be used to further quality of life benefit. To answer this question, the participants of an NKF and FDA sponsored symposium in the USA proposed to design adequately powered, blinded randomized controlled trials of anemia treatment using patient-reported outcomes as primary rather than secondary endpoints [ 39 ].

The mean difference of achieved hemoglobin levels between the patient groups allocated to higher and lower anemia correction targets was 1. In the latter trial, the physical function score on the quality of life questionnaire at 12 months showed a clinically meaningful increase of 7.

However, this study was done in relatively disabled chronic hemodialysis patients with congestive heart failure or ischemic heart disease. Among the subsequent three RCTs done in non-dialysis-dependent CKD patients with less comorbidities, only CREATE found significant quality-of-life benefit, in response to an achieved mean hemoglobin increase of 1.

Erythropoiesis-stimulating agents (ESAs) -

The RR and range for each group filled diamonds and the overall RR open diamond are shown. Patients that progressed to RRT included those that began dialysis or received a transplant. In one trial a patient withdrew because of sepsis and AKI [ 48 ].

This event was included in the RRT endpoint of that study. No patients progressed to dialysis in either arm of the Lim [ 42 ] trial making it unsuitable for inclusion in a meta-analysis with a RRT endpoint.

The remaining 18 anemia correction trials had a combined total of subjects; in the treatment arm higher Hb and in the comparator low Hb control arm. Trials were of varying size; 3 had over subjects.

The initial and achieved Hbs in the 2 groups are shown in Table 4. Overall, With meta-analysis, the RR random effects of progression to RRT was 1.

This lack of effect on disease progression is supported in 18 trials by other assessments of change in renal function, including proteinuria, or creatinine based markers where there were no significant differences reported between groups Table 4.

However, in one trial time to a doubling in serum creatinine was significantly slower in the ESA group Kuriyama [ 41 ]. This anemia correction meta-analysis does not assess direct ESA effects per se because subjects in both arms may have received ESAs.

Thus the absence of benefit argues that anemia correction per se is not reno-protective. In 6 of the 18 anemia correction trials, subjects in the comparator arm did not receive ESAs [ 18 , 19 , 38 — 43 ]. These trials included a total of subjects. Meta-analysis showed a trend towards improvement in the progression to RRT in the ESA treatment group but this did not reach statistical significance; the RR according to the random effects model was 0.

The result was similar using the mixed effects model. Heterogeneity was low. Measures of serum creatinine over time showed no statistical difference in 6 of the 7 trials. Thus this select analysis also does not support either direct or indirect anemia correction beneficial effect on renal disease progression by ESAs.

We assessed potential beneficial effects of ESA treatment on acute or chronic renal disease. One potential benefit is that ESAs might increase renal tissue survival and therefore renal function following ischemic events due to an interaction of ESAs with receptors resident on the surface of renal cells resulting in an anti-apoptotic effect.

Alternatively, there may be mitigation of the negative effects of anemia, since anemia is associated with an increased risk of renal disease progression and allograft loss over the long term [ 56 , 57 ].

However, these meta-analyses showed no clear benefit of short-term ESAs in AKI and transplant trials, where there was little change in Hb levels, arguing an absence of direct benefit. There was also no significant ESA benefit in longer-term anemia correction trials, regardless of whether the comparator group received or did not receive ESAs.

Thus there appeared to be little short or long-term reno-protective benefit of ESAs, via direct via activation of EPOR or via an interaction of ESA with an EPOR:CD hybrid receptor [ 9 ] or indirect increased Hb mechanisms.

The lack of clear benefit of ESAs on renal disease is consistent with earlier meta-analyses. A meta-analysis with patients at risk for AKI showed no benefit of ESAs on incidence of AKI [ 58 ].

Another meta-analyses of effects of ESAs on CKD patients also showed no clear benefit on progression to RRT, comparing ESA treatment to no treatment [ 59 ] or comparing high vs low Hb targets [ 60 , 61 ], nor was there was an association between ESA dose and annual GFR change or progression to ESRD [ 62 ].

Overall and to date, the potential cyto-protective effects of ESAs reported in animal models have generally not translated into benefit in humans, according to other studies examining benefit with other ischemic tissues [ 63 ].

There was no significant benefit of ESAs on infarct size in a meta-analyses of patients with acute ST-segment elevation myocardial infarction [ 64 , 65 ], and no effect on nonfatal heart related events in a meta-analysis of ESA-treated patients with heart failure [ 66 ]. There was also no difference in a meta-analysis of retinopathy of prematurity in infants treated with ESAs [ 67 ].

There was no benefit of either ESA or increased Hb in an ESA trial on patients with traumatic brain injury [ 68 , 69 ], and there was no benefit in a phase 3 trial with ESA treatment of stroke patients [ 70 ]. Taken together, these observations suggest that ESAs may not have the broad, robust, non-hematopoietic protective abilities described by some investigators, at least not in humans.

The gap between preclinical reports of benefit of ESAs in animals, and the absence of similar robust benefit in humans, has several explanations.

Dose and dose regimens may be different, or the animal studies used homogeneous animal types under controlled conditions that cannot be mimicked in the clinic.

Another possibility is that a benefit may have been unobservable because of the trial designs used. In this AKI meta-analysis the subjects were primarily cardiac patients and did not have only ischemia to the kidney as in animal studies and therefore may be immune to potential reno-protective ESA benefits.

There could also be other induced mechanisms that may confound the outcome data. For example, sepsis can affect outcomes and blood pressure can increase with ESA treatment and can negatively correlate with renal outcomes [ 71 , 72 ]. However, control of blood pressure did not affect progression to ESRD in a clinical trial [ 73 ].

Alternatively, the beneficial conclusions of preclinical animal studies need to be reconsidered. There are many reports in animals showing a lack of effect of ESAs [ 1 , 74 ]. The reno-protective hypothesis assumes that EPOR is present, and functional, at significant level on the surface of renal cells.

However reports of EPOR presence are either assumed according to responses in tissue culture and in animals, or based on western or immunohistochemistry studies with anti-EPOR antibodies now shown to be nonspecific [ 75 ]. Recently a specific antibody to EPOR was discovered and western blots on renal tissue showed few, if any, detectable EPOR raising further questions about the validity of the hypothesis [ 10 ].

These meta-analyses have limitations. Majorities of included trials were small, single center, and had modest event rates. The anemia correction trials were larger, but conclusions around direct effects were confounded by the frequent use of ESAs in the comparator arm, though trials where the comparator arm did not receive ESAs similarly showed no benefit.

Within each grouping CKD progression, AKI, transplantation there were differences in patient selection, treatment regimen and outcome definition. Finally, the meta-analyses were based on aggregated, not individual patient level data, which precluded adjustments for confounding factors such as age and comorbidities.

In contrast to some preclinical studies demonstrating reno-protection by ESAs in animals, anemia correction, prophylaxis or post-injury intervention with ESAs provided no significant clinical reno-protection in humans. This suggests that ESAs may not have robust, nor reproducible direct, or indirect, benefits on renal function.

DT participated in the design, performed statistical analysis, contributed to the interpretation of data and revision of the manuscript. ZE participated in the design, evaluation of the data, quality assessments, contributed to the interpretation of data and drafting and revision of the manuscript.

All authors have reviewed and approved the final manuscript. SE and DT are stockholders in Amgen Inc, a manufacturer and distributer of ESAs.

SE was an employee, but currently receives no financial compensation from Amgen. Dianne Tomita is an employee of Amgen. Studies also show that ESAs can increase the risk of heart attack, heart failure, stroke or blood clots in patients who use these drugs for other conditions.

ESAs work by stimulating the bone marrow to produce red blood cells. ESAs are approved for the treatment of anemia low red blood cells resulting from chronic kidney failure, chemotherapy, certain treatments for Human Immunodeficiency Virus HIV , and also to reduce the number of blood transfusions during and after certain major surgeries.

As part of the REMS, a Medication Guide explaining the risks and benefits of ESAs must be provided to all patients receiving ESAs. In addition to the Medication Guide, Amgen was required to develop the ESA APPRISE Assisting Providers and Cancer Patients with Risk Information for the Safe use of ESAs Oncology program for healthcare professionals who prescribe ESAs to patients with cancer.

Under the ESA APPRISE Oncology program, Amgen will ensure that only those hospitals and healthcare professionals who have enrolled and completed training in the program will prescribe and dispense ESAs to patients with cancer.

Amgen is also required to oversee and monitor the program to ensure that hospitals and healthcare professionals are fully compliant with all aspects of the program.

Patients using ESAs should:. Patients with chronic kidney failure includes patients on dialysis and those not on dialysis. The ESA APPRISE Oncology program requires that all healthcare professionals who prescribe ESAs for patients with cancer do the following:.

Healthcare professionals not enrolled in the ESA APPRISE Oncology program will not be able to prescribe ESAs for use in patients with cancer. As part of the enrollment in the ESA APPRISE Oncology program, healthcare professionals must attest to their understanding of the following:.

For the most current information on ESAs, please see Information on Erythropoiesis-Stimulating Agents ESA Epoetin alfa marketed as Procrit, Epogen , Darbepoetin alfa marketed as Aranesp.

The goals of the REMS for the ESAs are: To support informed decisions between patients and their healthcare professionals who are considering treatment with an ESA by educating them on the risks of ESAs.

Additional Information for Patients: Patients with cancer Patients using ESAs should: Understand the risks associated with use of ESAs. These risks include: ­ ESAs may cause tumors to grow faster. Be aware that their healthcare professional has received special training about the use of ESAs in patients with cancer.

Read the Medication Guide to understand the benefits and risks of using an ESA. Talk with their healthcare professional about any questions they may have about using ESAs.

Be aware that they will be asked to sign an acknowledgment form that says they have talked with their healthcare professional about the risks of ESAs.

This form must be signed before patients begin a course of treatment with an ESA. Patients with chronic kidney failure includes patients on dialysis and those not on dialysis Patients using ESAs should: Know that the use of ESAs can increase the risk for stroke, heart attack, heart failure, blood clots, and death.

Get blood tests while using ESAs. The test results may help guide the course of therapy and lower the risks of using these drugs.

Heart disease prevention, randomized controlled trials of Erythropoiesis-stimulating agents (ESAs) sample size examined intermediate outcomes, but only trials with hard outcomes could settle this issue convincingly. In contrast to expectations based on epidemiological studies, the randomized controlled trials of large sample size performed in patients with chronic kidney disease in the last two decades have convincingly shown that full anemia correction, as compared to partial anemia correction, is associated with increased risk of adverse events and mortality and that the increased risk outweighs potential benefit. Although transfusion needs decrease and quality of life increases with actively raised hemoglobin levels in severely anemic patients with chronic kidney disease, any benefit of increasing hemoglobin levels above
