- Abstract
Background: Thrombotic microangiopathy (TMA) in patients with connective tissue disease is rare but life-threatening. In particular, the survival rate of patients with dermatomyositis (DM) that develop TMA is low. The effectiveness of plasma exchange (PEX) therapy is unclear for the treatment of TMA secondary to DM. Case presentation: We describe a case of a 28-year-old woman who developed severe DM complicated by aspiration pneumonia from dysphagia and acute kidney injury. The patient was unresponsive to corticosteroids and intravenous immunoglobulin (IVIG) therapy and developed TMA. In this case, immunofluorescence of skin biopsy revealed that complement activation was involved in the pathogenesis of DM. After 6 PEX therapies, thrombocytopenia improved. She was successfully treated by intensive care and PEX therapy. Conclusions: PEX therapy was effective to treat TMA secondary to DM associated with complement activation.
