[Atipical uremic hemolityc syndrome in pregnancy]

Pregnancy-associated atypical hemolytic uremic syndrome. Case report

Pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS) is a rare disease. There are only few reports in the literature, and most are in the puerperium period. It is a thrombotic microangiopathy (TMA) characterized for microangiopathic hemolytic anemia, thrombocytopenia, and renal dysfunction. We report the case of a pregnant patient at 26.3 gestation weeks, who developed clinical features of TMA, neurological alterations, and septic shock; then after fetus and placental delivery, no clinical improvement was observed; a diagnostic protocol was performed due to suspicion of P-aHUS, showing improvement after the plasma exchange sessions and eculizumab. We present here a brief review of the case since it is an entity that needs to be suspected during pregnancy when TMA features and requires an immediate diagnosis to provide timely treatment.

Management of atypical uremic hemolytic syndrome in pregnant patient

Atypical uremic haemolytic syndrome is a variant of thrombotic micro-andiopathy characterized by non-autoimmune hemolytic anemia, thrombocytopenia and acute renal failure as a result of excessive activation of the complement. Up to 60% of patients have mutations in the genes that encode the complement system. A disensing factor is required for its manifestation, including gestation. It is an entity with a high morbidity, which can decrease drastically if an early diagnosis is made and appropriate treatment is initiated. Administration of ecuilizumab has demonstrated rapid process disruption, reducing the need for extrarenal purification therapies and improving renal function and patient prognosis.
