In most cases, the atypical hemolytic uremic syndrome (aHUS) is a genetic disease resulting from defects in the regulation of the complement cascade, which conditions the development of thrombotic microangiopathy. Clinically, aHUS presents with acute kidney injury, thrombocytopenia, and microangiopathic hemolytic anemia, with frequent renal and extrarenal thrombotic phenomena. Early diagnosis and treatment are essential. Plasmapheresis is an alternative treatment being frequently used considering the high cost of eculizumab, despite its lower clinical efficacy. This article describes the clinical case of a patient admitted to intensive care with a personal history of aHUS diagnosed 10 years ago, with recurrent aHUS triggered by viral infection. The patient presented with acute kidney injury and thrombocytopenia. Despite the institution of admission of plasmapheresis, the clinical evolution was only favorable after the administration of eculizumab, highlighting the importance of early initiation of this therapy.

A Case of Thrombotic Microangiopathy Secondary to Hypertensive Emergency: Presentation, Management, and Distinguishing Features.

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.

Background: Postpartum hemorrhage is considered a risk factor for pregnancy-associated complement-mediated hemolytic uremic syndrome (CM-HUS; previously known as atypical hemolytic uremic syndrome) but has not been systematically studied.
Objectives: To systematically examine the role of postpartum hemorrhage in precipitating CM-HUS and to describe the characteristics of postpartum hemorrhage-associated CM-HUS, its prognosis and recommended management.
Methods: A systematic review of individual participant data from case series and reports in addition to a case series from our institution.

Brucellosis is an infectious disease caused by bacteria of the genus , predominantly affecting livestock and humans through contact or consumption. It is a major public health challenge, particularly in developing countries. Symptoms can be mild to severe, making diagnosis difficult and often resulting in more chronic problems if those issues are not addressed.
