AI Article Synopsis

  • Two patients with sickle cell disease experienced thrombotic microangiopathy (TMA) after painful crises and acute chest syndrome during hospitalization.
  • Both showed severe anemia, high lactate dehydrogenase levels, low platelets, decreased consciousness, organ damage, and schistocytes in blood.
  • They were effectively treated with fresh frozen plasma and plasmapheresis, highlighting the importance of recognizing TMA in SCD for better patient survival.

Article Abstract

Objective: To describe two cases of patients who had thrombotic microangiopathy (TMA) associated with sickle cell disease (SCD).

Case Description: Both patients started with a painful crisis and had acute chest syndrome during hospitalization. They showed significant worsening of hemolytic anemia, with very high levels of lactate dehydrogenase, thrombocytopenia, lowered level of consciousness, organ damage and the presence of schistocytes in peripheral blood. Due to the possibility of TMA, despite the very rare association with SCD, they were treated with fresh frozen plasma replacement and plasmapheresis, with good response.

Comments: TMA is a serious, life-threatening disease, characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ damage. The association of SCD and TMA is difficult to diagnose, since they can share a similar clinical presentation. Recognizing this association and promptly instituting treatment may impact the survival of these patients.

Cyclosporine A (CsA) is a commonly used immunosuppressant, but its association with thrombotic microangiopathy (TMA) is rarely reported. In recent years, CsA has been used in pregnant women with autoimmune diseases or previous immune-related adverse pregnancies. Our case involves a 34-year-old female who developed typical laboratory indicators of TMA while using CsA to improve pregnancy outcomes.

Haemotoxicity is the most common complication of systemic envenoming following snakebite, leading to diverse clinical syndromes ranging from haemorrhagic to prothrombotic manifestations. Key haematological abnormalities include platelet dysfunction, venom-induced consumption coagulopathy, anticoagulant coagulopathy and organ-threatening thrombotic microangiopathy. Diagnostic methods include the bedside whole blood clotting test, laboratory coagulation screening and other advanced methods such as thromboelastogram and clot strength analysis.

Snakebite is a neglected public health problem in tropical countries. Snakebite envenomation-associated acute kidney injury (SBE-AKI) is a major complication accounting for significant morbidity and mortality. The pathogenesis of SBE-AKI may be multifactorial, including prerenal AKI secondary to hemodynamic alterations, intrinsic renal injury, immune-related mechanisms, venom-induced consumptive coagulopathy and capillary leak syndrome.

Snakebite-associated acute kidney injury (AKI) poses a significant health burden in the South Asia region, resulting in considerable morbidity and mortality. Multiple factors contribute to the pathogenesis of AKI following snakebites, including hypotension, intravascular haemolysis, disseminated intravascular coagulation, rhabdomyolysis, thrombotic microangiopathy (TMA) and direct nephrotoxicity. Clinical features manifest as anuria, oliguria, haematuria, abdominal pain and hypertension.
