Muscle Strength Deterioration: A Critical Factor in Chronic Kidney Disease Progression
A study by Antoine Chatrenet and colleagues, published in the Clinical Kidney Journal, explores the impact of chronic kidney disease (CKD) on the relationship between skeletal muscle mass and muscle strength, highlighting an often-overlooked aspect of CKD progression.
The study analyzed data from 1098 patients, assessing appendicular skeletal muscle mass (ASM) and maximal voluntary force (MVF) across different stages of CKD.
Findings reveal that muscle force declines in later stages of CKD (G3 to G5) independently of muscle mass, indicating a deterioration in muscle quality rather than quantity.
Despite similar rates of sarcopenia across all CKD stages, patients in the early stages (G1-G2) exhibited a higher likelihood of recovery.
Why is this important?
This research underscores the importance of evaluating muscle function, not just mass, in patients with CKD. The decline in muscle strength, irrespective of muscle mass, suggests that interventions to improve muscle quality could be crucial.
Understanding these dynamics can lead to more targeted therapies and rehabilitation programs aimed at preserving muscle function, thereby enhancing the quality of life and potentially slowing CKD progression.
This study emphasizes the need for early intervention in CKD to mitigate neuromuscular impairments that contribute to morbidity.
Glomerular Hyperfiltration as a Risk Factor for Cardiovascular Disease in Type 2 Diabetes
A study led by Seung Min Chung, published in the Clinical Journal of the American Society of Nephrology, evaluates the impact of glomerular hyperfiltration (GHF) on cardiovascular disease (CVD) risk among patients with type 2 diabetes mellitus.
The retrospective cohort study analyzed 1,952,053 patients, classifying them based on their estimated glomerular filtration rate (eGFR) into different percentile groups to observe the incidence of CVD, which included myocardial infarction, stroke, and heart failure.
Results indicated an inverted J-shaped relationship between eGFR and CVD, with the highest risks observed in the lowest and highest eGFR percentiles, highlighting GHF as a significant risk factor, especially for myocardial infarction and heart failure.
Why is this important?
Glomerular hyperfiltration (GHF) is one of the earliest changes in diabetic kidney disease. This study demonstrated that GHF is a significant risk factor for cardiovascular disease.
Typically overlooked in clinical assessments, GHF is linked with an elevated risk of severe cardiovascular events, suggesting a need for early detection and targeted interventions to mitigate these risks.
Understanding and addressing GHF can lead to improved cardiovascular outcomes and provide critical insights into the progression of kidney disease in diabetic patients, emphasizing the necessity for a shift in clinical focus towards the early stages of renal changes.
Dietary Inflammation and Chronic Kidney Disease Risk: Insights from the Comprehensive Dietary Inflammation Index
A recent published in the Clinical Journal of the American Society of Nephrology introduces a novel dietary inflammatory score— the Comprehensive Dietary Inflammation Index (CDII)—to assess the link between diet and the onset of chronic kidney disease (CKD).
Developed using data from 9,814 participants initially free of CKD in the Atherosclerosis Risk in Communities Study, the CDII quantifies dietary inflammation based on the consumption of eight specific food groups.
Over 19 years, participants adhering to a pro-inflammatory diet, as indicated by higher CDII scores, exhibited a 28% increased risk of developing CKD, suggesting that dietary inflammation plays a significant role in CKD onset.
Why is this important?
The findings underscore the importance of dietary choices in managing inflammation and preventing chronic kidney disease.
By identifying pro-inflammatory diets as a modifiable risk factor, this study provides a practical tool—the CDII—for clinicians and patients to assess and adjust dietary habits.
Reducing the intake of pro-inflammatory foods could emerge as a key strategy to mitigate CKD risk, offering a preventive approach that can be integrated into broader dietary recommendations and public health policies.

Impact of Body Mass on Kidney Disease Progression in Autosomal Dominant Polycystic Kidney Disease
A study by Kristen L. Nowak et al., published in the Clinical Journal of the American Society of Nephrology, investigates the effect of body mass index (BMI) on the progression to end-stage kidney disease (ESKD) in patients with autosomal dominant polycystic kidney disease (ADPKD).
Utilizing data from the HALT PKD trials, the study divides participants into early-stage (eGFR: 91±17 mL/min/1.73m2) and late-stage (eGFR: 48±12 mL/min/1.73m2) groups. It was found that obesity significantly increased the risk of ESKD in early-stage ADPKD but not in late-stage patients.
This differentiation highlights the nuanced role of body weight in the progression of ADPKD, particularly emphasizing the importance of managing obesity early in the disease trajectory to mitigate risks.
Why is this important?
The findings highlight a crucial window during the early stages of ADPKD, during which weight management could play a pivotal role in slowing the progression to ESKD.
Understanding how BMI influences disease outcomes could lead to more targeted interventions and inform clinical guidelines, potentially improving long-term outcomes for patients with ADPKD. This study underscores the importance of personalized treatment approaches based on disease staging and individual risk factors such as obesity.
Review article of the month
Music Therapy Slows Cognitive Decline in CKD
This scoping review published in Nephrology Dialysis Transplantation investigates the clinical application and benefits of music-based interventions (MBIs) in patients with mild cognitive impairment (MCI) and explores their potential use in chronic kidney disease (CKD) populations.
The systematic search included sixteen studies, predominantly randomized control trials, assessing the effects of various MBIs, ranging from passive music listening to active music-making.
The findings suggest significant cognitive improvements and behavioral benefits from these interventions in MCI patients, with active interventions showing greater cognitive benefits and receptive approaches aiding behavioral symptoms.
Despite the absence of studies focusing specifically on CKD patients, the high prevalence of MCI within this group indicates a critical area for future research on the application of MBIs to potentially improve cognitive and depressive symptoms in CKD patients.
