What is the relationship between cystatin C (CysC) levels and all-cause, cardiovascular disease (CVD), and cancer mortality in US adults with metabolic syndrome (MetS)?

In one paragraph

Cystatin C / eGFR Kidney Test, a prospective cohort study (J Clin Endocrinol Metab 2024, PMID 38597157) — during a mean follow-up of 15.3 years, 819 deaths occurred. The abstract for Cystatin C / eGFR Kidney Test states no limitations.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

Higher cystatin C levels are linked to increased risk of death from all causes, cardiovascular disease, and cancer in adults with metabolic syndrome.

The question

What is the relationship between cystatin C (CysC) levels and all-cause, cardiovascular disease (CVD), and cancer mortality in US adults with metabolic syndrome (MetS)?

What they tested

The study implicitly hypothesized that higher cystatin C levels would be associated with increased mortality rates in MetS patients.

How they did it

This prospective cohort study utilized data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES), including 1980 MetS participants. Researchers used fitted curves, Kaplan-Meier survival curves, Cox regression analysis, and receiver operating characteristic curves to assess the relationship between CysC levels and mortality outcomes.

What they found

During a mean follow-up of 15.3 years, 819 deaths occurred. Higher CysC levels were linked to increased all-cause, CVD, and cancer mortality rates. After adjustment, CysC was associated with all-cause mortality (HR 1.63), CVD mortality (HR 1.53), and cancer mortality (HR 1.53). Participants in the highest CysC tertile had higher risks for all-cause (HR 1.87), CVD (HR 1.97), and cancer mortality (HR 1.72) compared to the lowest tertile. CysC showed higher predictive efficacy for mortality outcomes than eGFR, urea nitrogen, creatinine, uric acid, and C-reactive protein. CysC alone had substantial predictive value for all-cause (AUC 0.773) and CVD mortality (AUC 0.726), which improved when combined with age (AUC 0.861 for all-cause, AUC 0.771 for CVD mortality).

Hazard Ratios for Mortality by Cystatin C Tertile in MetS Patients
Values shown: Hazard Ratio
All-cause mortality1.87
CVD mortality1.97
Cancer mortality1.72

Hazard ratios for all-cause, CVD, and cancer mortality in the highest cystatin C tertile compared to the lowest tertile among metabolic syndrome patients.

What it means

Elevated cystatin C levels are associated with a higher risk of all-cause, cardiovascular disease, and cancer death in patients with metabolic syndrome. Cystatin C may serve as a predictor for all-cause and cardiovascular mortality in this population.

Limitations

The abstract does not explicitly state limitations of the study.

Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

Cystatin C / eGFR Kidney Test

Across large cohorts and meta-analyses, cystatin C-based eGFR is at least as accurate as creatinine-based eGFR and is more strongly associated with death, cardiovascular events, and end-stage kidney disease—in one ~90,750-person consortium meta-analysis it markedly improved risk reclassification for death—and it…
