Coagulopathy due to an acquired factor V inhibitor and subsequently thrombosis

To the Editor: We have read with interest the letter to the Editor by Beris et al. [I], which described infection-induced transient increase in the platelet count observed only in May-Hegglin anomaly, and not in idiopathic thrombocytopenia (ITP), which may lead to the discovery of the May-Hegglin anomaly. We 121 as well as others [3-51 have demonstrated partial correction of thrombocytopenia in ITP during viral [3, Therefore, May-Hegglin anomaly cannot be differentially diagnosed between ITP on the episode of post-infection transient partial correction of thrombocytopenia.
