ABSTRACT Background Glomerular endotheliosis is an essential component in the pathophysiology of gestational hypertension (GH) and preeclampsia (PE) which results in renal dysfunction. This is not always detected by routine renal function tests, such as serum creatinine, urea, and uric acid. Cystatin C, an endogenous cysteine protease inhibitor, is completely absorbed by renal tubules and has been shown to be an ideal marker of glomerular filtration rate (GFR), which needs to be evaluated in assessing renal dysfunction occurring in GH and PE. Aims The present study is designed to evaluate serum cystatin C levels in normal pregnancy, GH, and PE and compare its efficacy with traditional renal function tests. Materials and methods In this prospective cross-sectional study, 75 subjects enrolled, comprised of 25 subjects each of normal pregnancy, GH, and PE. Serum cystatin C, blood urea, serum creatinine, serum uric acid, and urinary protein/creatinine ratio were estimated in all subjects prior to delivery. Results All renal parameters including cystatin C were significantly raised in GH and PE compared with control group. However, only serum cystatin C level (and no other renal parameters) was significantly higher in PE group compared with GH group. Area under the curve for cystatin C was maximum (0.917) compared with other parameters. Cystatin C had a higher sensitivity and specificity than other conventional markers. Conclusion Serum cystatin C is a better marker of renal dysfunction in hypertensive pregnancies. How to cite this article Singh A, Gupta M, Ranjan R, Saini V, Gupta SK.

Abstract Background: Serum cystatin C, a cysteine protease inhibitor, has been suggested as a new marker of glomerular filtration rate (GFR). This study explored the possibility of replacing the creatinine clearance (CrCl) estimation of GFR with cystatin C in early detection of renal impairment in cancer patients on chemotherapy. Methods: Serum creatinine and cystatin C concentrations as well as 24-h CrCl were determined simultaneously in 72 cancer patients. Among them, 60 were treated with combined chemotherapy with cisplatin (CDDP). Creatinine was determined enzymatically with a spectrophotometric method. Serum cystatin C was determined by a particle-enhanced turbidimetric immunoassay. Results: Cystatin C and creatinine correlated significantly (P = 0.001) with CrCl. The correlation was significantly better for cystatin C than creatinine (r = 0.84 vs 0.74; P = 0.01). Stepwise regression analysis identified no differences for the correlations between cystatin C and CrCl in patients with or without metastases (r = 0.82 and 0.84, respectively) as well as before treatment and before the fourth cycle of chemotherapy (r = 0.70 and 0.75, respectively). A cystatin C cutoff concentration of 1.33 mg/L had 87% sensitivity and 100% specificity for detecting CrCl <78 mL/min. ROC analysis indicated that cystatin C was superior to serum creatinine for predicting CrCl <78 mL/min (P <0.04). Conclusions: Serum cystatin C is superior to serum creatinine for detection of decreased CrCl and potentially for the estimation of GFR in cancer patients independent of the presence of metastases or chemotherapy.

Acute kidney injury (AKI) dramatically increases sepsis mortality, but AKI diagnosis is delayed when based on serum creatinine (SCr) changes, due in part, to decreased creatinine production. During experimental sepsis, we compared serum cystatin C (sCysC), SCr, and blood urea nitrogen (BUN) to inulin glomerular filtration rate (iGFR) before or 3–18 h after cecal ligation and puncture (CLP)-induced sepsis in CD-1 mice. sCysC had a faster increase and reached peak levels more rapidly than SCr in both sepsis and bilateral nephrectomy (BiNx) models. sCysC was a better surrogate of iGFR than SCr during sepsis. Combining sCysC with SCr values into a composite biomarker improved correlation with iGFR better than any biomarker alone or any other combination. We determined the renal contribution to sCysC handling with BiNx. sCysC and SCr were lower post-BiNx/CLP than post-BiNx alone, despite increased inflammatory and nonrenal organ damage biomarkers. Sepsis decreased CysC production in nephrectomized mice without changing body weight or CysC space. Sepsis decreased sCysC production and increased nonrenal clearance, similar to effects of sepsis on SCr. sCysC, SCr, and BUN were measured 6 h postsepsis to link AKI with mortality. Mice with above-median sCysC, BUN, or SCr values 6 h postsepsis died earlier than mice with below-median values, corresponding to a substantial AKI association with sepsis mortality in this model. sCysC performs similarly to SCr in classifying mice at risk for early mortality. We conclude that sCysC detects AKI early and better reflects iGFR in CLP-induced sepsis. This study shows that renal biomarkers need to be evaluated in specific contexts.
