Thrombotic microangiopathy (TMA) is a severe condition characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage, often involving the kidneys. Complement-mediated hemolytic uremic syndrome (cHUS), a rare form of TMA, arises from dysregulated alternative complement pathway activation, frequently due to genetic mutations. We report the case of a 23-year-old male presenting with TMA secondary to a heterozygous mutation in the membrane cofactor protein (MCP/CD46) gene.

Thrombocytopenia frequently occurs in patients before, during, and after admission to Pediatric Intensive Care Units (PICUs). In critically ill children, it is often due to multifactorial causes and can be a sign of significant organ dysfunction. This review summarizes the potential causes/mechanisms of thrombocytopenia in acutely ill children, their identification, and treatments, with special attention paid to septic patients.

Microangiopathic hemolytic anemia (MAHA) is a rare subtype of hemolytic anemia characterized by elevated hemolytic markers and red blood cell destruction. Though uncommon, MAHA can occur as a complication of acute pancreatitis because of the associated inflammatory response. Patients with MAHA secondary to pancreatitis show favorable outcomes when treated with plasma exchange.

Recognizing anemia and thrombpenia in acute and emergency medicine is easy. Acute (microangiopathic hemolytic) anemia and thrombopenia can be a sign of thrombotic microangiopathy (TMA). TMA syndromes are potentially life-threatening diseases.
View Article and Find Full Text PDFBackground: When haemolytic anaemia, thrombocytopenia and renal failure are present, a thrombotic microangiopathic (TMA) condition should be suspected. We describe the various differential diagnoses of primary TMA syndromes, their clinical findings, clinical workup and treatment.
Case Presentation: A previously healthy man in his fifties was hospitalised with anaemia, thrombocytopenia, bilirubinaemia and acute renal failure.
