An update for atypical haemolytic uraemic syndrome: Hospital Universitari de Bellvitge. Hospital Universitario 12 de Octubre. Madrid 7 Enfermedades Renales Hereditarias.

Microoangiopatica 8 Departamento de Medicina Celular y Molecular. La actividad investigadora del Dr. Haemolytic uraemic syndrome HUS is a clinical entity defined as the triad of nonimmune haemolytic anaemia, thrombocytopenia, and acute renal failure, in which the underlying lesions are mediated by systemic thrombotic microangiopathy TMA.

In recent years, research has established the key role that the complement system plays in the induction of endothelial damage in patients with aHUS, through the characterisation of multiple mutations and polymorphisms in the genes that code for certain complement factors. Eculizumab is a monoclonal antibody that inhibits the terminal fraction of the complement protein, blocking the formation of a cell membrane attack complex.

In prospective studies in patients with aHUS, administering eculizumab produces a rapid and sustained interruption in the TMA process, with significant hemolusis in long-term renal function and an important decrease in the need for dialysis or plasma therapy.

In this document, we review and bring up to date the important aspects of this disease, with special emphasis microanngiopatica how recent advancements in diagnostic and therapeutic processes can modify the treatment of patients with aHUS.

La toxina Shiga ejerce un efecto lesivo directo sobre el endotelio vascular desencadenando diversos eventos celulares y vasculares que conducen al desarrollo de MAT 2. El SHUa se considera una enfermedad ultra-rara. En mujeres, el embarazo es un frecuente factor desencadenante de SHUa 15, En los pacientes con anticuerpos anti-FH, se ha observado que el microangioaptica inmunosupresor concomitante a la TP puede mejorar los resultados 22,63, En microangiopatida pacientes adultos con sospecha de SHUa, se recomienda iniciar precozmente eculizumab.

Previamente, es necesario vacunar a todos los pacientes frente a Neisseria meningitidis preferentemente con vacunas tetravalentes conjugadas frente a los serotipos A, C, Y y W La recogida de muestras debe realizarse previamente al inicio del tratamiento y enviarse a un laboratorio de referencia tabla 7. Se recomienda la recogida de muestras de los injertos de los pacientes trasplantados renales por SHUa para futuros estudios.
