What We Miss in Patients With Persistent Thrombocytopenia During the Dengue Season.

Dengue is an arboviral illness caused by Aedes aegypti and usually presents with fever and thrombocytopenia. This decrease in platelet counts is observed to revert after the seroconversion phase of the infection. On the other hand, immune thrombocytopenia (ITP) is an autoimmune phenomenon with pathological destruction of platelets. It is a diagnosis made only after exclusion of other causes. Evans syndrome is a combination of ITP with autoimmune haemolytic anaemia (AIHA). Here, we present a case series of patients with persistent thrombocytopenia during the dengue season and the aftermath of it at a single tertiary centre in North India, with concluding diagnoses of ITP and AIHA.
