Thrombocytopenia and Bleeding in Chronic Kidney Disease: A Case of Acquired Von Willebrand Syndrome.

Acquired von Willebrand disease is a rare condition with laboratory findings similar to the inherited type, which can be autosomal dominant or recessive. This case describes a rather rare clinical situation of a 65-year-old man with stage 4 chronic kidney disease who also had acquired von Willebrand syndrome (AvWS) with thrombocytopenia and bleeding. The patient had a complaint of easy fatigability, easy bruising, and prolonged bleeding from small cuts. The patient's initial laboratory workup included thrombocytopenia, which on further evaluation established the diagnosis of AvWS due to chronic kidney disease. More specific examination revealed reduced activity of the von Willebrand factor. The patient was managed with desmopressin and von Willebrand factor concentrates and there was a transient rise in platelet count and relief of symptoms of bleeding. This case underlines the importance of AvWS in any differential diagnosis of thrombocytopenia in patients with chronic kidney disease. This report aims to provide recommendations for early identification and management of AvWS to improve the outcome.
