Idiopathic infantile arterial calcification with cardiac, renal and central nervous system involvement

Area of Science:

• Pediatric Cardiology
• Neonatology
• Vascular Biology

Background:

• Idiopathic infantile arterial calcification (IIAC) is a rare and severe condition affecting newborns.
• IIAC presents with widespread arterial calcification, leading to significant morbidity and mortality.
• Early diagnosis and intervention are crucial for managing IIAC.

Observation:

• A 2-week-old infant presented with failure to thrive, neurological deficits, renal dysfunction, and cardiac abnormalities.
• Clinical signs were consistent with severe idiopathic infantile arterial calcification.
• The infant exhibited significant vascular calcification on diagnostic imaging.

Findings:

• Treatment with diphosphonate therapy led to a complete resolution of the arterial calcifications.
• The infant showed remarkable clinical improvement following diphosphonate administration.
• At 2 years of age, the child is thriving but requires ongoing management for arterial hypertension.

Implications:

• Diphosphonate therapy is a highly effective treatment for idiopathic infantile arterial calcification.
• Early intervention with diphosphonates can reverse vascular calcification and improve long-term outcomes.
• Long-term monitoring for complications such as hypertension is essential in IIAC survivors.
