    Abstract Purpose of review: In this report, we summarize why the availability of cystatin C is important across a variety of clinical scenarios, the recent literature on when, why and in whom cystatin C testing should be considered, and how nephrologists can take practical steps to incorporate cystatin C testing into their practice.
    Recent findings: Large intra-individual discrepancies between estimated glomerular filtration rate by creatinine (eGFRcr) and estimated glomerular filtration rate by creatinine eGFRcys (known as eGFRdiff) are observed in at least 1 in 4 people. These differences are seen more commonly among more vulnerable individuals: older adults, females, non-White individuals and those living with multiple medical conditions. A large eGFRdiff, where eGFRcys is lower than eGFRcr, is associated with a plethora of adverse outcomes, including medication-associated adverse events, acute kidney injury, cardiovascular disease, kidney failure and all-cause mortality. Among studies that have measured GFR, eGFRcr-cys usually provides the most accurate estimation of kidney function compared to mGFR, including among participants with large discrepancies between eGFRcr and eGFRcys.
    Summary: Cystatin C improves sensitivity and specificity of chronic kidney disease diagnosis, improves detection of harmful acute and chronic changes in kidney function, improves precision of treatment eligibility and safety, and may reduce healthcare inequalities. Better education, curiosity, and motivation among nephrologists could substantially improve the availability and utilization of cystatin C.

    Abstract For over 70 years, serum creatinine has remained the primary index for detection and monitoring of kidney disease. Tubulointerstitial damage and fibrosis are highly prognostic for subsequent kidney failure in biopsy studies, yet this pathology is invisible to the clinician in the absence of a biopsy. Recent discovery of biomarkers that reflect distinct aspects of kidney tubule disease have led to investigations of whether these markers can provide additional information on risk of chronic kidney disease (CKD) progression and associated adverse clinical end points, above and beyond estimated glomerular filtration rate and albuminuria. These biomarkers can be loosely grouped into those that mark tubule cell injury (eg, kidney injury molecule 1, monocyte chemoattractant protein 1) and those that mark tubule cell dysfunction (eg, α

    Abstract Purpose of review: The goal of this update is to raise awareness of clinical scenarios where cystatin C has clear and immediate benefits as an alternative glomerular filtration rate (GFR) biomarker to supplement creatinine. An additional goal is to focus the estimated GFR (eGFR) controversy onto medication prescribing for agents with narrow therapeutic windows where better GFR estimation will lead to improved medical care.
    Recent findings: Equations that include cystatin C predict GFR more accurately than serum creatinine in children, adults, and older adults with larger effects among persons who are acutely ill. Numerous studies have evaluated medication dosing based on either GFR estimate; vancomycin was the most frequently studied drug and its target level and elimination were better predicted by cystatin C. Overall, approaches to medication dosing and monitoring that include cystatin C concentrations have been shown to result in a better achievement of drug trough levels. Furthermore, cystatin C offers the opportunity to avoid the race coefficient that is required for any current creatinine-based eGFR equation, which has been appropriately criticized for introducing unnecessary imprecision, assumptions and values on GFR estimation.
    Summary: Hospital laboratories must make cystatin C available for clinical care to improve the safety and efficacy of medications that have narrow therapeutic windows.

    Abstract Objective: It is unknown whether weight change or physical fitness is associated with chronic kidney disease (CKD) risk among nondiabetic adults with obesity.
    Methods: This was a prospective, longitudinal cohort study of adults with obesity without baseline CKD or diabetes enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA). Linear mixed-effects and multistate models were adjusted for demographics, time-varying covariates including blood pressure, and comorbidities these were used to examine associations of weight change and slow walking pace (<2 miles/h) with (i) rate of annual estimated glomerular filtration rate (eGFR) decline and (ii) incident CKD, defined as eGFR
    Results: Among 1208 included MESA participants (median BMI 33.0 kg/m
    Conclusions: Slow walking pace and weight gain were associated with CKD risk among adults with obesity who did not have diabetes at baseline.
