title: [Changes of serum cardiotrophin I and cystatin C in preeclampsia and clinical significance thereof].
abstract: OBJECTIVE
  To investigate the changes and of serum cardiotrophin I (cTN I) and cystatin C in preeclampsia clinical significance thereof.
  
  
  METHODS
  Peripheral blood samples were collected from 40 women with preeclampsia, aged 29 (18 - 39), with the medium gestational age of 35 weeks, and 40 age- and gestational age-matched controls. Serum cTN I and cystatin C were determined with ELISA and serum levels of creatinine kinase, creatinine, and uric acid were assayed by automatic biochemical analyzer. Comparison was made between the 2 groups.
  
  
  RESULTS
  The serum cTn I of the preeclampsia group was 0.59 microg/L +/- 0.42 microg/L, significantly higher than that of the control group (0.09 microg/L +/- 0.22 microg/L P < 0.001), and the serum cystatin C of the preeclampsia group was 1.64 mg/L +/- 0.47 mg/L, significantly higher than that of the control group (1.08 mg/L +/- 0.19 mg/L, P < 0.001). And the serum cardiotrophin I and cystatin C concentrations of the patients with severe preeclampsia were 0.66 microg/L +/- 0.40 microg/L and 1.72 mg/L +/- 0.46 mg/L respectively, both significantly higher than those of the patients with mild preeclampsia (0.17 microg/L +/- 0.26 microg/L and 1.21 mg/L +/- 0.37 mg/L respectively, P < 0.001 and 0.05 respectively).
  
  
  CONCLUSIONS
  Serum cTn I and cystatin C levels are elevated in preeclampsia and the elevation is associated with the severity of preeclampsia, suggesting that serum concentrations of cTn I and cystatin C are useful markers in the early diagnosis of cardiac and renal injury in patients of preeclampsia.
