Abstract

Various laboratory parameters are commonly used to assess the efficacy of biological treatment (BT). The aim of our study was to assess the correlation between platelet (PLT) indices: (mean platelet volume (MPV), plateletcrit (PCT), platelet distribution width (PDW)), C-reactive protein (CRP) and endoscopic picture in the course of infliximab induction regimen in ulcerative colitis (UC) patients. The study enrolled 46 patients with UC – 32 men and 16 women. They were administered infliximab (standard induction therapy). Laboratory tests (CRP and PLT indices) and colonoscopy were performed in all patients during the induction regimen – at 0, 2, and 6 weeks and in follow-up six weeks after the completion of induction therapy. The study revealed a statistically significant decrease in CRP and PLT, and an increase in MPV, together with improvement of endoscopic picture (p <0.001) (MAYO score, MAYO endoscopic subscore) in all patients. PCT and PDW values remained in normal ranges before BT and after the finish of the induction regimen. PCT correlated positively with CRP before the introduction of BT (p = 0.018). In addition, positive correlations between PCT and PLT count were noticed before infliximab induction regimen and in follow-up after the finished of therapy (p <0.001). Additionally, a negative correlation between PLT count and MPV prior to the first dose of infliximab was observed (p=0.032). Our data suggest that PLT indices could be useful biomarkers for determining active UC and for assessing the efficacy of BT. From what we know, this is the first survey devoted to PLT parameters in Polish patients with UC.
