Relationship between serum or urine TIMP-1 levels and the stages of CKD / 中国实用内科杂志

ABSTRACT

Objective To investigate the relationship between serum or urine tissue inhibitor of metalloproteinases-1 (TIMP-1)levels and the stages of chronic kidney disease (CKD).Methods Serum and urine level of TIMP-1 were measured by enzyme-linked immunoadsorbent assay (ELISA) in 122 CKD patients and 40 healthy controls.Serum cystatin-C (CystC),parathyroid hormone (PTH),low-density lipoprotein (LDL)and other markers were determined simultaneously.Correlationanalysis between TIMP-1 level and degree of renal function were performed.Results Serum and urine TIMP-1 of the patients in CKD group was significantly higher than that in control group (P
