Abstract
Background
Lower serum Cr levels in women as compared to men result in underestimation of renal dysfunction and lower model for end-stage liver disease-sodium scores leading to reduced access to liver transplantation in women compared to men with comparable hepatic dysfunction.
Aim
The aim of this study was to determine the gender differences in serum Cr, cystatin C, and other endogenous glomerular filtration rate (GFR) biomarkers, measured and estimated GFR, Cr clearance, and Cr production rates.
Methods
We measured GFR by iothalamate plasma clearance in 103 patients with cirrhosis and assessed gender differences in GFR, Cr clearance and production rate, serum Cr, cystatin C and other endogenous GFR biomarkers including beta-trace protein, beta-2 microglobulin, and dimethylarginines.
Results
Comparison of men and women showed significantly lower values for mean serum Cr (0.97 vs. 0.82 mg/dl, P = 0.023), and Cr production rate (13.37 vs. 11.02 mg/kg/day, P = 0.022). In contrast to the serum Cr and Cr production rate, men and women exhibited no significant differences in the means of serum cystatin C and other GFR biomarkers, measured GFR, GFR estimated using Cr–cystatin C GFR equation for cirrhosis, measured and estimated Cr clearances. After controlling for age, race, weight, height, and GFR, female gender remained associated with lower serum Cr levels (P = 0.003). Serum cystatin C levels were not associated with gender, age, race, weight, height, C-reactive protein, and history of hypothyroidism.
Conclusions
Our results suggest that cystatin C and endogenous GFR biomarkers other than Cr, measured GFR, GFR estimated by Cr–cystatin C GFR equation for cirrhosis, measured and estimated Cr clearance minimized between-gender biases in accounting for renal function in patients with cirrhosis. Therefore, serum cystatin C should be measured as a complementary test to serum Cr when renal function is assessed in patients with cirrhosis, particularly in women and those with sarcopenia.
