Congenital syphilis: clinical manifestations in premature infants
1Department of Paediatrics, National Cheng Kung University Medical College, Tainan, Taiwan, R.O.C.
Insights
Congenital syphilis in premature infants presents unique symptoms like skin lesions and bone changes. Early diagnosis and penicillin treatment are crucial for these vulnerable newborns.
Area of Science:
- Neonatal Medicine
- Pediatric Infectious Diseases
- Syphilology
Background:
- Congenital syphilis, a serious infection in newborns, can have varied presentations.
- Premature infants may exhibit distinct clinical features compared to full-term infants.
Purpose of the Study:
- To describe the clinical characteristics of congenital syphilis in premature neonates.
- To highlight key diagnostic considerations and treatment recommendations.
Main Methods:
- Retrospective case series analysis of 13 premature infants with congenital syphilis.
- Review of clinical data, including physical examination, bone imaging, and cerebrospinal fluid analysis.
Main Results:
- Unusual palm and sole desquamation occurred in 62% of infants.
- Bone abnormalities (periosteal reaction/metaphyseal dystrophy) were present in 85%.
- Major manifestations included bone changes, hepatosplenomegaly, respiratory distress, skin lesions, and jaundice.
Conclusions:
- Clinical presentation of congenital syphilis in premature neonates differs from previous reports.
- Congenital syphilis should be considered in premature infants with suggestive symptoms.
- Prompt diagnosis and adequate penicillin therapy are essential.
Abstract:
During the 4-year period February 1989 to January 1993, 13 premature babies aged 1-21 days and with congenital syphilis were admitted to the National Cheng Kung University Hospital. Of the 13 premature infants, 8 (62%) had unusual desquamation over palms and soles. Bone changes with periosteal reaction and/or metaphyseal dystrophy were observed in 11 cases (85%). Three mothers were diagnosed as being infected during pregnancy; 2 were treated with penicillin. The clinical features of congenital syphilis in premature neonates are somewhat different from those previously reported. Bone changes, hepatosplenomegaly, respiratory distress, skin lesions, especially over the soles and palms, cerebrospinal fluid abnormalities, and jaundice were the major manifestations in our series. In premature infants with these symptoms and signs, congenital syphilis should be considered as one of the differential diagnoses. Once the diagnosis of congenital syphilis is made, adequate penicillin therapy should be given.
