Patient and Clinician Perspectives: To Create a Better Future for Chronic Kidney Disease, We Need to Talk About Our Kidneys.

Chronic kidney disease (CKD) affects more than one in ten people worldwide. However, results from the REVEAL-CKD study suggest that it is often not diagnosed. Many patients are therefore unaware that they have CKD, putting them at increased risk of disease progression and complications. Empowering patients with knowledge about CKD will allow them to become active participants in their own care, driving improvements in diagnosis rates and changing patient outcomes for the better. In this article, we provide patient and clinician perspectives on the importance of early CKD diagnosis and management. We present an overview of the tests commonly used to diagnose CKD in clinical practice, as well as actionable suggestions for patients, clinicians, and health policymakers that could help improve disease detection and treatment. Navdeep Tangri, a nephrologist and epidemiologist at the University of Manitoba, and Jane DeMeis, a patient living with chronic kidney disease, discuss how results from the REVEAL-CKD study highlight the need for change to improve management of chronic kidney disease.

Patient Management and Clinical Outcomes Associated with a Recorded Diagnosis of Stage 3 Chronic Kidney Disease: The REVEAL-CKD Study.

INTRODUCTION: Guidelines for the treatment of chronic kidney disease (CKD) recommend early intervention and management to slow disease progression. However, associations between diagnosis and CKD progression are not fully understood. METHODS: REVEAL-CKD (NCT04847531) is a retrospective observational study of patients with stage 3 CKD. Data were extracted from the US TriNetX database. Eligible patients had two consecutive estimated glomerular filtration rate (eGFR) measurements indicative of stage 3 CKD (≥ 30 and < 60 ml/min/1.73 m2) recorded 91-730 days apart from 2015 to 2020. Diagnosed patients were included if their first CKD diagnosis code was recorded at least 6 months after their second qualifying eGFR measurement. We assessed CKD management and monitoring practices for the 180 days before and after CKD diagnosis, annual eGFR decline in the 2 years before and after CKD diagnosis, and associations between diagnostic delay and post-diagnosis event rates. RESULTS: The study included 26,851 patients. After diagnosis, we observed significant increases in the prescribing rate of guideline-recommended medications such as angiotensin-converting enzyme inhibitors (rate ratio [95% confidence interval]: 1.87 [1.82, 1.93]), angiotensin receptor blockers (1.91 [1.85, 1.97]) and mineralocorticoid receptor antagonists (2.23 [2.13, 2.34]). Annual eGFR decline was significantly reduced following a CKD diagnosis, from 3.20 ml/min/1.73 m2 before diagnosis to 0.74 ml/min/1.73 m2 after diagnosis. Delayed diagnosis (by 1-year increments) was associated with elevated risk of CKD progression to stage 4/5 (1.40 [1.31-1.49]), kidney failure (hazard ratio [95% confidence interval]: 1.63 [1.23-2.18]) and the composite of myocardial infarction, stroke and hospitalization for heart failure (1.08 [1.04-1.13]). CONCLUSIONS: A recorded CKD diagnosis was associated with significant improvements in CKD management and monitoring practices and attenuated eGFR decline. Recorded diagnosis of stage 3 CKD is an important first step to reduce the risk of disease progression and minimize adverse clinical outcomes. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT04847531.

Chronic kidney disease (CKD) is a long-term condition in which the function of the kidneys is reduced. Kidney function is monitored using a measurement called the estimated glomerular filtration rate. CKD can be separated into stages of severity, ranging from 1 (mild) to 5 (severe), using estimated glomerular filtration rate. Mild to moderate CKD (stages 1­3) is difficult to diagnose because there are usually no symptoms. In this study from the REVEAL-CKD programme, we looked at the effects of having undiagnosed stage 3 (moderate) CKD and examined how a CKD diagnosis affects disease management and worsening of the condition. Using a database of medical records for patients in the USA called TriNetX, we looked at data from over 26,000 patients with stage 3 CKD who were identified using estimated glomerular filtration rate measurements. We found that healthcare teams prescribed significantly more guideline-recommended medications and did more clinical monitoring in the 180 days after a CKD diagnosis than they did before the diagnosis. Additionally, the rate of decline in kidney function slowed after a CKD diagnosis. Delaying diagnosis by 1 year increased the risk of deterioration of the condition by 40%, the risk of needing a kidney transplant or long-term dialysis treatment by 63% and the risk of major heart and blood vessel diseases (known as cardiovascular events) by 8%. Our findings suggest that diagnosis of stage 3 CKD is an important first step to reduce the risk of the disease worsening and other complications. Video Abstract (MP4 82773 KB).

Early intervention and intensive management of patients with diabetes, cardiorenal, and metabolic diseases.

Increasing rates of obesity and diabetes have driven corresponding increases in related cardiorenal and metabolic diseases. In many patients, these conditions occur together, further increasing morbidity and mortality risks to the individual. Yet all too often, the risk factors for these disorders are not addressed promptly in clinical practice, leading to irreversible pathologic progression. To address this gap, we convened a Task Force of experts in cardiology, nephrology, endocrinology, and primary care to develop recommendations for early identification and intervention in obesity, diabetes, and other cardiorenal and metabolic diseases. The recommendations include screening and diagnosis, early interventions with lifestyle, and when and how to implement medical therapies. These recommendations are organized into primary and secondary prevention along the continuum from obesity through the metabolic syndrome, prediabetes, diabetes, hypertension, dyslipidemia, nonalcoholic fatty liver disease (NAFLD), atherosclerotic cardiovascular disease (ASCVD) and atrial fibrillation, chronic kidney disease (CKD), and heart failure (HF). The goal of early and intensive intervention is primary prevention of comorbidities or secondary prevention to decrease further worsening of disease and reduce morbidity and mortality. These efforts will reduce clinical inertia and may improve patients' well-being and adherence.

Role of Primary Care Clinicians in the Management of Patients With Type 2 Diabetes and Cardiorenal Diseases.

Individuals with type 2 diabetes are at increased risk of both renal and cardiovascular events. The convergence of type 2 diabetes, chronic kidney disease, and cardiovascular disease, including heart failure, requires management by a multidisciplinary health care team. Primary care clinicians are likely to be the first and most frequent point of contact for individuals with type 2 diabetes who are at high risk of cardiorenal disease and therefore play a pivotal role in early diagnosis, establishment of effective treatment strategies, and coordination of care. This article presents a clinical perspective with multidisciplinary collaboration on a patient case representative of those seen in routine clinical practice. The authors assess reasons why patients may not receive evidence-based care and identify opportunities to initiate therapies that reduce cardiovascular and renal events in the primary care setting.

The Changing Landscape of Glycemic Targets: Focus on Continuous Glucose Monitoring.

Continuous glucose monitoring (CGM) provides comprehensive assessment of daily glucose measurements for patients with diabetes and can reveal high and low blood glucose values that may occur even when a patient's A1C is adequately controlled. Among the measures captured by CGM, the percentage of time in the target glycemic range, or "time in range" (typically 70-180 mg/dL), has emerged as one of the strongest indicators of good glycemic control. This review examines the shift to using CGM to assess glycemic control and guide diabetes treatment decisions, with a focus on time in range as the key metric of glycemic control.

Management of Daily Glycemic Fluctuations in Patients With Type 2 Diabetes.

Traditional measures of overall glucose control, such as glycated hemoglobin (A1C), may not fully capture short-term, rapid changes in blood glucose. With the availability of multiple options to control A1C, glycemic fluctuations have emerged as an additional therapeutic goal for the management of type 2 diabetes (T2D).

Review of proton pump inhibitors for the initial treatment of heartburn: is there a dose ceiling effect?

Proton pump inhibitors (PPIs) are widely used in clinical practice. However, concerns have been expressed about their long-term use, particularly with regard to bone health, Clostridium difficile infections, and drug interactions with platelet aggregation inhibitors. There has been limited guidance for clinicians concerning appropriate dose selection of PPIs for the initial treatment of heartburn. This review explored whether published clinical trials provide evidence of a ceiling above which higher PPI doses do not provide additional clinical benefit over the lowest approved dose. All articles of randomized, controlled clinical trials in nonerosive gastroesophageal reflux disease (GERD) in which the effects of two or more doses of the same PPI on symptomatic relief of heartburn were quantified as a study endpoint were identified and analyzed through PubMed searches up to the end of September 2010. The majority of trials evaluated provided no evidence that higher PPI doses were superior to the lowest approved dose for the initial treatment of heartburn. There were no clinically relevant findings with respect to dose dependence and safety outcomes in these studies. Efficacy outcomes from the trials suggest there may be a dose ceiling effect and highlight the need for further research on the use of the lowest effective PPI doses as an appropriate strategy in the initial treatment of uncomplicated heartburn. Observational studies and some meta-analyses have suggested that long-term PPI pharmacotherapy might be associated with safety concerns, which necessitate the periodic evaluation of therapeutic benefit in terms of symptom resolution and regimen tolerability. However, evidence to date suggests that use of the lowest effective dose for the indication is not associated with significant adverse events, particularly in the short term. Clinical practice suggests that patients requiring long-term treatment should be maintained on the lowest dose necessary to control symptoms, and monitored for potentially confounding factors that may lead to safety concerns.

Role of the primary care provider in the diagnosis and management of heartburn.

BACKGROUND: Heartburn affects an estimated 42% of the US population. Often, patients are able to recognize symptoms and self-treat heartburn; however, patients with more persistent and/or troublesome symptoms should be evaluated by a physician or other healthcare provider. SCOPE: This review focuses on the role of the primary care provider in the diagnosis and treatment of heartburn. METHODS: A search was conducted on PubMed (to November 2009) and articles relevant to the management of heartburn by a primary care provider topic were selected. FINDINGS: Diagnostic tools, such as endoscopy, and ambulatory pH monitoring, are recommended for advanced assessment of patients with frequent heartburn to avert misdiagnosis and to identify complications of reflux disease. Over-the-counter and prescription treatments for frequent heartburn symptoms include antacids, histamine(2)-receptor antagonists (H(2)RAs), antacid/H(2)RA combinations, and proton pump inhibitors (PPIs). Among these, PPIs represent the mainstay of acute and maintenance treatment regimens in reflux disorders and are more effective than H(2)RAs for long-term use due to the development of tolerance to the latter therapy. While once-daily PPI therapy may be sufficient in most patients, a few may require twice-daily PPI therapy to alleviate their symptoms. This review is limited by its relatively narrow focus on articles cited in PubMed. CONCLUSION: The primary care provider is ideally situated to advise patients on the best treatment option for their condition and to provide follow-up care if required.

Patient self-treatment using lansoprazole for frequent nighttime heartburn. Commentary.

Lansoprazole, at both the 15-mg and 30-mg doses, was very effective at a statistically significant level and was well tolerated in reducing frequent nighttime heartburn. Thus, lansoprazole 15 mg is an appropriate starting dose for the management of frequent nighttime heartburn.

Lansoprazole 15 mg once daily for 14 days is effective for treatment of frequent heartburn: results of 2 randomized, placebo-controlled, double-blind studies.

OBJECTIVE: To investigate the efficacy and safety of a 14-day treatment period with lansoprazole 15 mg for frequent heartburn in patients who are likely to select a nonprescription medication before consulting a prescriber. METHODS: Adults with untreated frequent heartburn > or = 2 days a week over the past month were recruited for 2 identical multicenter, double-blind studies conducted with a 1-week screening and heartburn medication washout, a 1-week placebo run-in, a 2-week placebo-controlled treatment, and a 1-week placebo follow-up. After the washout and placebo run-in, subjects were randomly assigned to receive lansoprazole 15 mg or placebo once daily for 14 days in a double-blind fashion. Antacid tablets were permitted as rescue medication. Endpoints included percentage of 24-hour days without heartburn (primary), percentage of night-times without heartburn, and percentage of subjects without heartburn during day 1 of treatment (secondary endpoints). Data were collected daily via an interactive voice response system. RESULTS: In studies 1 and 2, 282 and 288 subjects, respectively, were randomly assigned to lansoprazole, and 282 in each study received placebo. The mean percentage of days without heartburn was greater among lansoprazole recipients compared with placebo recipients (P < 0.0001). Significantly more subjects treated with lansoprazole also reported no night-time heartburn and no heartburn during day 1 of the 14-day treatment. Adverse events were infrequent and were similar for lansoprazole and placebo groups. CONCLUSION: During the 14-day treatment period in a population with frequent heartburn who were likely to select a medication without consulting a prescriber, lansoprazole 15 mg once daily showed rapid and sustained effectiveness throughout a 24-hour period and was well tolerated.

Can intensive statin therapy halt the progression of atherosclerosis? Recent evidence and potential implications for patient management.

A number of studies using various imaging techniques have demonstrated that intensive lipid lowering with statins can halt or delay the progression of atherosclerosis and even, in some cases, lead to plaque regression. Improvements in atheroma burden with intensive statin therapy appear to be related not just to decreasing low-density lipoprotein cholesterol but also to anti-inflammatory and antiproliferative effects. Clinical trial results also suggest that achieving low-density lipoprotein cholesterol levels even lower than those currently recommended can produce improved clinical outcomes across a range of patient types. Given this body of evidence, it appears appropriate to use intensive statin therapy to treat dyslipidemic patients at high risk for coronary heart disease.
