Juvenile Hemochromatosis Connecting Cardiac Arrest and Hypogonadotropic Hypogonadism in a Young Woman

Year: 2024

Type: article

Abstract: Juvenile hemochromatosis (JH) is a subtype of hereditary hemochromatosis, a genetic disorder characterized by excessive iron absorption and deposition in various organs, leading to cardiomyopathy, cirrhosis, and diabetes. Endocrine dysfunction is a common manifestation and may appear years before end-organ damage. This report describes a rare case of JH, emphasizing the consequences of delayed diagnosis. A 28-year-old woman with a history of hypogonadotropic hypogonadism presented with cardiac arrest complicated by acute renal failure and cerebral vascular accidents. She initially exhibited signs of severe cardiomyopathy and multiorgan failure, which led to workup for an underlying cause. Laboratory values showed significantly elevated ferritin and transferrin saturation. Subsequent genetic screening revealed HJV gene pathogenic variants consistent with juvenile hemochromatosis. Treatment involved aggressive iron chelation therapy and outpatient referral for cardiac transplant. This case calls for heightened awareness and early screening of JH, particularly among patients with unexplained endocrine dysfunction. Early diagnosis and treatment are paramount in preventing irreversible organ damage and improving patient outcomes.
