“…[74,75] Several patients have been reported to be in remission with blood pressure control alone without PE. [76–78] In this case, malignant hypertension-induced TMA was considered; however, severe thrombocytopenia was observed and atypical. Several previous reports on COVID-19-related TMA have described patients with a history of hypertension.…”

Rationale: Coronavirus disease 2019 (COVID-19) is an infectious disease that often causes complications in multiple organs and thrombosis due to abnormal blood coagulation. This case report aimed to describe the clinical course of COVID-19-associated thrombotic microangiopathy (TMA) and reviewed the comprehensive information on TMA, thrombotic thrombocytopenic purpura (TTP), and atypical hemolytic uremic syndrome associated with COVID-19 in the past literature. Patient concerns: A 46-year-old Japanese man was diagnosed with human immunodeficiency virus infection 10 years ago and treated with antiretroviral therapy. The patient presented with fever, malaise, hematuria, and bilateral upper abdominal discomfort for the past 4 days. Diagnoses: COVID-19-associated TMA was diagnosed based on a positive polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 and laboratory findings such as thrombocytopenia, acute kidney injury, and hemolytic anemia. Malignant hypertension and human immunodeficiency virus infection were also considered as differential diagnoses of TMA. Interventions: Considering the possibility of TTP, plasma exchange was performed, and glucocorticoids were administered. Hemodialysis was performed for acute kidney injury. Antihypertensive drugs were administered to control the high blood pressure. Outcomes: Platelet count and renal function improved, and hemodialysis was no longer required. The patient was in good general condition and was discharged from the hospital. Lessons: COVID-19-associated TMA should be considered as a differential diagnosis during the COVID-19 epidemic. Excessive inflammation and severe COVID-19 are not essential for TMA development. Early intervention using conventional TMA treatments, such as plasma exchange and corticosteroids, might be important in improving prognosis while differentiating between TTP and atypical hemolytic uremic syndrome. Antihypertensive therapy may be helpful in the treatment of COVID-19-associated TMA.

“…Hypertension-associated microangiopathy and atypical hemolytic uremic syndrome share a similar ultrastructural appearance with light microscopy. In our case, severe uncontrollable hypertension appeared to trigger complement activation and endothelial damage leading to TMA [ 6 , 7 ]. Moreover excellent response to eculizumab further confirmed this.…”
