Challenges in managing severe homozygous protein c deficiency: a case report.

Abstract

Protein C deficiency is a rare autosomal recessive disorder associated with a high risk of thromboembolic complications. This case report describes the challenges in managing a 23-year-old woman with severe homozygous protein C type 1 deficiency diagnosed since early infancy. Her medical history included misdiagnosed cellulitis, recurrent thrombosis, and permanent vision loss in one eye. The laboratory workup confirmed a diagnosis of severe protein C deficiency. Management involved a combination of fresh frozen plasma (FFP), protein C concentrate, warfarin, and heparin, with ongoing challenges due to recurrent thrombosis and anaphylaxis to FFP. This case highlights the challenges in the diagnosis and management of severe protein C deficiency. Although current treatment options provide partial control, further research is crucial to develop safer and more effective therapies to improve long-term outcomes for affected patients.
