Perinatal Infections: An Important Etiological Risk Factor for Mineralizing Angiopathy.

Area of Science:

• Pediatric Neurology
• Neonatal Medicine
• Infectious Diseases

Background:

• Mineralizing angiopathy is an emerging cause of ischemic stroke in pediatric populations.
• The etiology of mineralizing angiopathy remains unclear, with congenital and perinatal infections being investigated.
• Understanding risk factors is crucial for preventing pediatric stroke.

Purpose of the Study:

• To investigate the prevalence of perinatal infections in children diagnosed with mineralizing angiopathy.
• To compare the incidence of perinatal infections between children with mineralizing angiopathy, focal cerebral arteriopathy, and non-stroke controls.
• To identify potential etiological links between perinatal infections and mineralizing angiopathy.

Main Methods:

• A case-control study involving 16 children with mineralizing angiopathy, 14 with focal cerebral arteriopathy, and 40 non-stroke patients.
• Detailed parental interviews were conducted to ascertain history of perinatal infections, specifically premature rupture of membranes (PROM) and neonatal sepsis.
• Statistical analysis was performed to compare infection prevalence across the groups.

Main Results:

• Perinatal infections were identified in 68.2% (8/16) of children with mineralizing angiopathy, including PROM and neonatal sepsis.
• None of the children with focal cerebral arteriopathy exhibited a history of perinatal infection.
• A history of PROM was reported in only 7.5% (3/40) of non-stroke controls, a statistically significant difference compared to the mineralizing angiopathy group.

Conclusions:

• Perinatal infections, including premature rupture of membranes and neonatal sepsis, are significantly more prevalent in children with mineralizing angiopathy.
• These findings suggest that perinatal infections may represent an important etiological risk factor for mineralizing angiopathy in pediatric stroke.
• Further research is warranted to elucidate the precise mechanisms linking perinatal infections to the development of mineralizing angiopathy.
