A 7-year-old girl's mysterious swelling episodes have finally been diagnosed with hereditary angioedema (HAE), a rare genetic disorder. This case report highlights the challenges of diagnosing pediatric HAE, which often mimics more common conditions like trauma, allergies, or infections. The girl's symptoms, including bruise-like discoloration and facial swelling, were initially attributed to various causes, but laboratory testing revealed the underlying genetic defect.
Her diagnosis of type 1 HAE, the most common form, led to family screening, uncovering her mother's undiagnosed condition. This case underscores the importance of early recognition and timely testing in HAE, as symptoms often begin in childhood. Abdominal attacks can mimic gastrointestinal issues, while facial swelling may be mistaken for an allergic reaction. A delayed diagnosis can lead to complications, especially from airway swelling, which can be life-threatening.
The report emphasizes the need for targeted therapies, which are often limited in resource-constrained settings. In the absence of these therapies, fresh frozen plasma (FFP) was used to manage the girl's acute attacks, providing a potential alternative for resource-limited areas. The success of this treatment suggests that FFP could be a valuable tool in managing HAE, especially when targeted therapies are not accessible.
This case also highlights the importance of family screening and patient education. The girl's mother, who had previously undiagnosed HAE, was identified through screening. Educating patients and their families about recognizing attacks, avoiding triggers, and emergency management is crucial for reducing morbidity and preventing severe complications. This case serves as a reminder of the ongoing challenges in diagnosing and managing HAE, particularly in pediatric populations, and the need for continued research and improved access to treatment.
