Abstract

Hereditary thrombotic thrombocytopenic purpura (TTP) and autosomal dominant polycystic kidney disease (ADPKD) are two distinct genetic diseases that may affect the kidneys through different mechanisms. ADPKD is a common genetic disorder that leads to exponential formation and growth of cysts replacing all segments of nephrons. Hereditary TTP is a rare autosomal recessive disorder that leads to the disseminated formation of arteriolar platelet-rich thrombi, which produce manifestations of various organs dysfunction. We present a case of a pregnant female with hereditary TTP co-occurring with ADPKD. To our knowledge, this is the first case in the literature describing the co-occurrence of ADPKD and hereditary TTP. We aim to describe the clinical course including the renal and the pregnancy outcomes, describe the consanguinity and family history, and try to explain the potential effect of one disease on the clinical course of the other.
