title: Does decreased mean platelet volume predict inflammation in chronic renal failure, dialysis, and transplanted patients?
abstract: OBJECTIVE
  Increased platelet activation contributes to cardiovascular mortality in chronic kidney disease patients (CKD). Larger platelets are more active and this increased activity had been suggested as a predictive biomarker for cardiovascular disease. In this study, we aimed to evaluate mean platelet volume (MPV) as an inflammatory marker in a broadened group of CKD patients. Our study is unique in literature as it covers all types of CKD including renal replacement therapies.
  
  
  METHODS
  200 patients (50 renal transplanted, 50 hemodialysis, 50 peritoneal dialysis, 50 chronic renal failure stages 3-4) were investigated who were between 18 and 76 years of age. The collected data included demographic properties, platelet count, MPV, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and hemoglobin. All of the patients had at least 12 month of therapy of either renal replacement modality.
  
  
  RESULTS
  The mean CRP value was detected statistically significantly higher in hemodialysis (HD) patients compared to the resting three groups of patients (p < 0.01). Mean CRP level was detected significantly higher in the pre-dialysis group compared to transplanted and peritoneal dialysis (PD) patients (p < 0.01). There is no statistically significant difference detected among the mean MPV values of all patient groups (p > 0.05).
  
  
  CONCLUSIONS
  ESR and CRP were significantly increased in hemodialysis patients compared to the other groups. We did not detect a significant difference among MPV between the groups. ESR was detected lowest in transplanted patients. Transplantation is coming forward as the favorable choice of renal replacement therapy which decreases inflammation.
