Hydrops fetalis secondary to Bart hemoglobinopathy.

Area of Science:

• Genetics
• Obstetrics
• Hematology

Background:

• Alpha-thalassemia is the leading cause of hydrops fetalis in Southeast Asian populations.
• Increasing immigration necessitates greater awareness of alpha-thalassemia as an obstetric concern in the US.
• Homozygous alpha-thalassemia (Bart hemoglobinopathy) results in fetal fatality and maternal complications.

Purpose of the Study:

• To review cases of homozygous alpha-thalassemia in a US hospital.
• To provide recommendations for antenatal screening, diagnosis, and management.
• To address the growing obstetric challenge posed by alpha-thalassemia.

Main Methods:

• Retrospective review of 18 cases of homozygous alpha-thalassemia.
• Analysis of clinical data and outcomes.
• Formulation of management guidelines.

Main Results:

• The study reviewed 18 cases, representing the largest series reported in the United States.
• Homozygous alpha-thalassemia was confirmed as a significant cause of fetal mortality and maternal morbidity.
• The findings underscore the need for targeted screening and management strategies.

Conclusions:

• Antenatal screening, diagnosis, and management protocols for alpha-thalassemia are crucial.
• Healthcare providers should be prepared for the increasing prevalence of this condition.
• Effective management can mitigate maternal morbidity associated with homozygous alpha-thalassemia.
