Congenital vesicular eruption caused by Haemophilus influenzae type b

Area of Science:

• Neonatal infections
• Perinatal infections
• Bacterial pathogenesis

Background:

• Haemophilus influenzae type b (Hib) is a significant cause of bacterial meningitis and sepsis in young children.
• While Hib is known to cause invasive disease, congenital infections are rare.
• Perinatal infections can pose serious risks to both mother and neonate.

Observation:

• A newborn presented with a vesicular eruption at birth, noted after premature rupture of membranes.
• Gram-negative rods were identified in the vesicular fluid.
• The mother developed postpartum septicemia caused by the same organism.

Findings:

• Haemophilus influenzae type b (Hib) was confirmed as the causative agent of the congenital vesicular eruption and maternal septicemia.
• Histological examination revealed amnionitis and funisitis, indicating intrauterine infection.
• Viral studies were negative, ruling out viral causes for the eruption.

Implications:

• This case highlights the potential for Haemophilus influenzae type b to cause congenital infections, including skin manifestations.
• Early diagnosis and prompt antibiotic therapy are crucial for favorable outcomes in both mother and neonate.
• Increased awareness of Hib as a cause of perinatal infections is warranted for clinicians.
