Learning Objectives
At the conclusion of this activity, participants should be able to
• Describe the disease burden of CKD and its impact on other comorbidities.
• Discuss three complications associated with diabetes and/or kidney dysfunction: heart failure, anemia, and hyperkalemia.
• Summarize current and evolving treatment options for patients with CKD.
• Apply the guideline recommendations for routine screening for CKD in patients with cardiorenal‐metabolic disease.

Anemia is a frequent complication of CKD and prevalence increases with disease severity
Note: Anemia was defined as serum hemoglobin ≤12 g/dL in women and ≤13 g/dL in men.1 The presence of anemia in earlier stages of CKD may be due to non‐renal causes (e.g., blood loss, inflammation, nutritional deficits).2
aStages of CKD were defined according to the National Kidney Foundation, with stage 5 as eGFR <15 mL/min/1.73 m2; bEstimated by applying the percentage of U.S. adults with anemia of CKD from the NHANES 2007‐2010 analysis (15.4%),1 to the U.S. CKD population from the Global Burden of Disease Study 2017 (~39 million);3 cWeighted percentage of U.S. adults with anemia of CKD (N=410) who reported being treated for anemia within the previous 3 months. Among these patients, the weighted means were 14.6% for stages 1‐2, 26.4% for stages 3‐4, and 43% for stage 5.

IV IronMay be associated with increased risk
of infection, acute reactions, and CV risk 2,5‐7
• Infection has been reported with some IV products6,7
• IV iron may be associated with iron overload/ hemosiderosis and severe acute reactions, including hypotension and dyspnea, as well as anaphylaxis2,8
• Benefit in NDD‐CKD should be weighed against desire to preserve venous access line2
Oral IronGI adverse events1,a and poor
GI absorption4
• Oral iron may not be effective due to poor tolerance and variable absorption2
– Gastrointestinal effects may be severe1,a
– Poor GI absorption associated with use of certain medications (e.g., proton pump inhibitors and calcium‐containing phosphate binders)3
• Generally modestly effective in NDD‐CKD and not effective in DD‐CKD4
High hepcidin, which is associated with chronic inflammation, may limit GI absorption of oral iron contributing to absolute iron deficiency and may also limit use of iron contributing to functional iron deficiency3,5
ESAs were a medical innovation in the management of anemia of CKD
• ESAs reduce the need for RBC transfusion, minimizing the risks of:1
– Transmission of blood‐borne viral diseases
– Volume overload
– Allosensitization that complicates kidney transplantation
– Transfusional hemosiderosis
• Guidelines recommend the use of ESAs and/or iron to avoid transfusion1
Prior to ESAs, iron and transfusions were the primary treatments for anemia2

• No additional comments
• NDD and DD patients:
– Initiate ESA when Hb <10 g/dL
– Upper Hb cutoff of 11 g/dL
• Classify as ESA hyporesponsive when no increase in Hb after ≥2 months of ESA treatment
• Address all correctable causes of anemia prior to initiation of ESA therapy
• Balance the potential benefits of reducing transfusions and anemia symptoms against the potential risks of ESA therapy
• NDD patients: In patients with Hb <10 g/dL , the decision to initiate ESA should be individualizeda
• DD patients: Initiate ESA when Hb 9 g/dL to 10 g/dL
• ESAs should not be used to maintain Hb above 11.5 g/dL (NDD‐CKD or DD‐CKD)
• Classify as ESA hyporesponsive when no increase in Hb after the first month of ESA treatment with appropriate weight‐based dosing
• Suggest avoiding repeated escalation in ESA dose beyond double the initial weight‐based dose

Risks of Blood Transfusions
• Infection transmission, immunologic sensitization, hyperkalemia, and volume overload1
• Longer wait time prior to transplantation2
• Higher risk of kidney rejection due to alloimmunization following transplant2
• Iron‐overload, raising concerns of damage to multiple organs, such as the liver and the heart, with chronic RBC transfusion3
• Consider when ESA is ineffective or in patients with high potential for harm from ESA
• Determine need not by a particular Hb threshold, but by presence of anemia symptoms
• Avoid (when possible) to minimize general risks related to its use
• Avoid (when possible) in patients eligible for organ transplantation

Guidelines for Blood Transfusions
Lower Hb levels are associated with increased morbidity and mortality in patients with NDD‐CKD Stage 3 or 4
Patients treated with erythropoietin‐stimulating agents or blood transfusions before the index hemoglobin were excluded from the analysis.aGFR estimated using MDRD equation; bThe hazard ratios adjusted for significant variables including time‐varying eGFR and Hb in patients with Hb <10.5 g/dL vs. >12.5 g/dL were 5.46 for ESKD, 5.27 for all‐cause mortality, and 2.18 for CV hospitalization (p<0.0001) for all comparisons.
HMO = health maintenance organization; MDRD = Modification of Diet in Renal Disease; NDD = non‐dialysis‐dependent.

Importance of Screening and Monitoring
Assessment of kidney function and damage
• Albuminuria ‒ AER ≥ 30 mg/24 hours‒ UACR ≥ 30 mg/g [≥ 3 mg/mmol]
• Urine sediment abnormalities• Electrolyte and other abnormalities due to tubular disorders• Abnormalities detected by histology• Structural abnormalities detected by imaging• History of kidney transplantation
Kidney damage
Kidney function
• Decreased eGFR‒ Calculate from the serum creatinine concentration‒ eGFR <60 mL/min/1.73 m2 (Stage 3a–5)
Diagnosis of CKD requires two abnormal measurements at least 3 months apart
AER = albumin excretion rate; UACR = urine albumin‐to‐creatinine ratio.

Guidelines recommend routine screening for CKD in patients with cardiorenal‐metabolic disease
• At least once yearly, assess urinary albumin (spot urinary ACR) and eGFR in patients with– T1D with duration of ≥5 years
– T2D
American Diabetes Association3
• Test for CKD using eGFR, creatinine, and ACR in people with‒ Diabetes
‒ Hypertension
‒ Acute kidney injury
‒ CVD (ischemic heart disease, chronic HF, peripheral or cerebral vascular disease)
‒ Structural renal tract disease, recurrent renal calculi or prostatic hypertrophy
‒ Multisystem disease with possible kidney involvement (e.g., systemic lupus erythematosus)
‒ Family history of ESKD or hereditary kidney disease
‒ Opportunistic detection of hematuria
NICE2
• Regular testing of high‐risk groups (including those with diabetes, hypertension, and CVD) can give an early indication of kidney damage
• Public health policies should include screening of these high‐risk populations

Burden of CKD is significant despite current approaches to diagnosis and treatment
KDIGO recommends routine CKD monitoring with increasing frequency as renal function declines5
Engage patients in risk factor reduction, and use multifactorial interventions to tailor treatment regimens to the individual
In patients with T2D, earlier stages (1‐3) of CKD are more common than late stages1
Roughly 10% of patients with CKD and T2D receive a diagnosis2
Progressive deteriorations in renal function increase the risk of adverse outcomes, such as risk of hospitalizations, CV events, death, and healthcare costs3,4
Several guidelines recommend regular screening of patients with increased risk5‐7
Intervene early Preserve renal functionProtect against CV risk, morbidity, and mortality
Lower eGFR and higher albuminuria are independently associated with increased adverse CV outcomes and premature death, which is worse in patients with diabetes8
While CV mortality is more likely than progression to ESKD,9 protecting against renal decline decreases CV risk10,11
