Abstract:
In Western developed countries, Listeria monocytogenesis not an uncommon pathogen in neonates. However, neonatal listeriosis has rarely been reported in Taiwan. We describe two cases collected from a single medical institute between 1990 and 2005. Case 1 was a male premature baby weighing 1558 g with a gestational age of 31 weeks whose mother had fever with chills 3 days prior to delivery. Generalized maculopapular rash was found after delivery and subtle seizure developed. Both blood and cerebrospinal fluid culture collected on the 1st day yielded L. monocytogenes. In addition, he had ventriculitis complicated with hydrocephalus. Neurologic development was normal over 1 year of follow-up after ventriculoperitoneal shunt operation. Case 2 was a 28-weeks' gestation male premature baby weighing 1180 g. Endotracheal intubation and ventilator support were provided after delivery due to respiratory distress. Blood culture yielded L. monocytogenes. Cerebrospinal fluid showed pleocytosis but the culture was negative. Brain ultrasonography showed ventriculitis. Sudden deterioration with cyanosis and bradycardia developed on the 8th day and he died on the same day. Neonatal listeriosis is uncommon in Taiwan, but has significant mortality and morbidity. Early diagnosis of perinatal infection relies on high index of suspicion in perinatal health care professionals.
Insights
Neonatal listeriosis, caused by Listeria monocytogenes, is rare in Taiwan but carries high risks. Early suspicion and diagnosis are crucial for managing this serious infant infection.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Microbiology
Background:
- Listeria monocytogenes is a known neonatal pathogen in Western countries.
- Neonatal listeriosis is infrequently reported in Taiwan, making its presentation and outcomes less understood in this region.
Observation:
- Two cases of neonatal listeriosis occurred between 1990-2005 at a single Taiwanese institute.
- Case 1: Premature infant (31 weeks) with maternal fever, rash, seizures, ventriculitis, and hydrocephalus, treated successfully.
- Case 2: Extremely premature infant (28 weeks) with respiratory distress, ventriculitis, who unfortunately died.
Findings:
- Listeria monocytogenes was identified in blood and cerebrospinal fluid in Case 1.
- Listeria monocytogenes was identified in blood in Case 2, with cerebrospinal fluid showing pleocytosis and brain ultrasonography revealing ventriculitis.
- The study highlights significant mortality and morbidity associated with neonatal listeriosis.
Implications:
- Neonatal listeriosis, though uncommon in Taiwan, necessitates a high index of suspicion among healthcare professionals.
- Prompt diagnosis and management are critical for improving outcomes in affected neonates.
- Further surveillance and awareness are needed to address this potentially devastating infection in the Taiwanese neonatal population.
