Thrombotic thrombocytopenic purpura (TTP) is a rare but frequently fatal complication of SLE. It occurs in the context of both active and inactive lupus and carries a worse overall prognosis than idiopathic acquired TTP. Recent advances in the knowledge and treatment of TTP do not seem to have brought similar improvements in the management and outcome of TTP in SLE. The illumination of the role of the von Willebrand factor multimer protease, ADAMTS13 in idiopathic TTP continues to enhance our comprehension of the pathogenesis of the disease and has contributed to improvements in diagnosis and management. We explore the overlap of TTP and SLE, and discuss the current understanding of the involvement of ADAMTS13 and its implications for patients with this uncommon form of microangiopathic haemolytic anaemia.

Malaria has become widespread, especially in sub-Saharan Africa, owing to disruptions experienced during the Covid-19 pandemic. Both cerebral malaria and acute kidney injury are important indicators of severe malaria. Depending on the degree of acute renal failure, hemodialysis/hemofiltration treatment is required.

Hemolytic-uremic syndrome (HUS) is a systemic complication of an infection with Shiga toxin (Stx)-producing enterohemorrhagic , primarily leading to acute kidney injury (AKI) and microangiopathic hemolytic anemia. Although free heme has been found to aggravate renal damage in hemolytic diseases, the relevance of the heme-degrading enzyme heme oxygenase-1 (HO-1, encoded by ) in HUS has not yet been investigated. We hypothesized that HO-1 also important in acute phase responses in damage and inflammation, contributes to renal pathogenesis in HUS.

Shiga toxin-producing (STEC) refers to a group of bacteria that can cause infections, which are common worldwide and pose a serious public health problem, as they can lead to conditions such as hemorrhagic colitis and hemolytic uremic syndrome (HUS). HUS is a disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, and renal failure. Determination of serogroups and toxin profiles of STEC is important for estimating their disease-causing potential and predicting epidemiological changes.

Thrombotic microangiopathies (TMA) are a group of conditions that present with varying degrees of microthrombi, thrombocytopenia, microangiopathic hemolytic anemia, renal dysfunction, and neurological impairment. Etiologies can be primary, such as thrombotic thrombocytopenic purpura (TTP), hemolytic uremic syndrome (HUS), and atypical hemolytic uremic syndrome (aHUS), or secondary, such as due to systemic infections, malignancies, immune-mediated conditions, and hypertensive emergencies. In hypertensive emergencies, this presentation can occur from mechanical stress placed on red blood cells as they pass through narrowed arteries due to edema and microangiopathic changes within the vessels themselves.

Background: Thrombotic microangiopathy (TMA) is a rare, life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage. Atypical hemolytic uremic syndrome (aHUS) is even less common, comprising less than 10% of hemolytic uremic syndrome (HUS) cases. aHUS in postpartum is associated with poor maternal outcomes, with the majority of cases resulting in end-stage renal disease.
