ABSTRACT
Sickle cell disease (SCD) is a qualitative hemoglobinopathy that can cause widespread sickling and vaso-occlusive events in all organ systems. Sickle cell hepatopathy is an umbrella term for various acute and chronic pathologies of the liver as a result of sickling in SCD patients. We present below the case of a 49-year-old woman who had an acute liver failure in the setting of a hepatic crisis with recovery after exchange transfusion. Hepatic involvement in SCD may be life-threatening. Understanding the etiology and severity of hepatic involvement by sickling is necessary for appropriate treatment.
ABSTRACT
The association of hyperhomocysteinemia with thrombosis has provoked debate in the medical literature. Although studies have found associations between moderate homocysteine elevations and thrombotic events, others dispute this relationship. We present herein the case of a 24-year-old male who presented with unprovoked bilateral submassive pulmonary emboli. Extensive hypercoagulability workup was notable for an elevated homocysteine level, in addition to low vitamin B12 and folate levels. Of note, the patient had a history of small bowel resection after trauma, which may have contributed to the aforementioned metabolic derangements, potentially increasing his risk for thrombosis and interfering with the efficacy of his anticoagulation.
