Nonimmune fetal hydrops and Down syndrome

Area of Science:

• Perinatology
• Genetics
• Pediatrics

Background:

• Nonimmune fetal hydrops (NIFH) is a serious condition characterized by fluid accumulation in a fetus.
• Trisomy 21, commonly known as Down syndrome, is a genetic disorder with various potential health complications.

Observation:

• A study identified six infants diagnosed with NIFH who also had trisomy 21.
• Cardiac malformations were noted in three of these infants.
• The typical features of Down syndrome were masked by generalized edema at birth.

Findings:

• The co-occurrence of NIFH and trisomy 21 was observed in this cohort of infants.
• Cardiac anomalies are a potential comorbidity in infants with both NIFH and Down syndrome.

Implications:

• The association between NIFH and Down syndrome necessitates genetic evaluation in infants presenting with NIFH.
• Early identification of trisomy 21 in NIFH cases can facilitate timely medical intervention and management.
• Chromosome analysis should be considered a crucial part of the diagnostic workup for NIFH.
