Summary
Congenital toxoplasmosis diagnosis can be delayed. A case report highlights a neonate with delayed serological findings, impacting timely antimicrobial therapy initiation.
Area of Science:
- Medical Parasitology
- Neonatal Infectious Diseases
- Immunology
Background:
- Congenital toxoplasmosis diagnosis typically relies on clinical signs and serological tests.
- Late-term fetal toxoplasmosis infection can result in neonates appearing healthy at birth.
- Delayed antibody production in neonates poses diagnostic challenges.
Observation:
- A case of maternal toxoplasmosis (infection) during the 15th-30th gestational week without treatment is presented.
- The neonate showed no clinical signs of toxoplasmosis at birth.
- The infant developed symptoms 2-3 weeks postnatally, with negative serology (complement fixation test, KBR) on day 24.
Findings:
- Serological conversion occurred between the 4th and 5th postnatal week.
- This delay necessitated a postponed start for specific antimicrobial therapy.
- The case underscores diagnostic difficulties in congenital toxoplasmosis.
Implications:
- Highlights the critical need for vigilant monitoring of infants born to mothers with recent toxoplasmosis infections.
- Emphasizes the limitations of early postnatal serological testing in diagnosing congenital toxoplasmosis.
- Suggests potential for improved diagnostic strategies and earlier therapeutic interventions for congenital toxoplasmosis.
