Abstract

To determine the relationship between the mean platelet volume (MPV) and the treatment efficacy of methylprednisolon in patients with primary immune thrombocytopenia (ITP) a descriptive correlation study was conducted on 76 ITP patients treated with standard-dose methylprednisolon at Military Hospital 103 from September in 2019 to September in 2024. The number of responders (complete responders was 42.1%) and non-responders were 71.1% and 28.9%, respectively. The mean of MPV in the complete responders or responders were higher compared to non-responders, with p = 0.001 and p = 0.014, respectively. The cut-off value of MPV for predicting treatment response with methylprednisolone was 9.85fL, the area under the curve (AUC) was 0.726, with p = 0.002. In predicting treatment response to methylprednisolone, the MPV index's sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 75.9%, 59.1%, 82%, 50%, and 71.1%, respectively. For patients with ITP, the MPV can be used to predict how well they will respond to standard-dose methylprednisolone.
