A Rare Intersection: Managing Thrombotic Thrombocytopenic Purpura in the Context of Dengue Fever.

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening condition that can lead to severe morbidity and mortality if untreated. This case report discusses a 31-year-old male with dengue fever who developed TTP, resulting in fatality despite timely diagnosis and comprehensive treatment. The patient presented with worsening symptoms, including body aches, gastrointestinal bleeding, and neurological issues. Initial treatment focused on managing dengue hemorrhagic fever, but TTP was later suspected, leading to the cessation of platelet transfusions and initiation of plasma exchange, steroids, and rituximab. Despite these efforts, the patient's condition deteriorated. This case underscores the challenges in managing TTP, especially when triggered by infections like dengue. The use of the PLASMIC score can be highly effective in suspecting TTP in these patients, allowing for the initiation of early management. While standard treatments include plasma exchange and immunosuppressive therapy, emerging treatments such as caplacizumab and the potential use of splenectomy may offer hope for better outcomes in the future.
