Bone Morphogenetic Protein-7 and disease progression in renal amyloidosis patients

AbstractIntroduction: Chronic kidney disease (CKD) is an important health care problem with increasing incidence. Early diagnosis, recognition and interventions to avoid the disease progression have great value. Even some risk factors for disease progression have been described; there are still some dark spots. Transforming growth factors (TGFs), particularly bone morphogenetic protein-7 (BMP7) take place in renal fibrosis. Our study aimed to evaluate the association between serum BMP7 levels and the progression of CKD. Materials and methods: Our study has been conducted between January 2008 and December 2010. Decrease in GFR by 10%, doubling of serum creatinine and need for renal replacement therapy have been set as progression end-points. Totally 93 patients (48 female, 45 male) have been included. Baseline and end of follow-up BMP7 levels have been measured. Results: At the end of the follow-up, 46 of 93 patients have been considered as having progressive CKD. Higher levels of serum BMP7 levels have be...
