Congenital syphilis revisited
Insights
Early congenital syphilis cases in Texas infants were often premature, low birth weight, and symptomatic. Diagnosis and treatment varied, suggesting under-reporting of asymptomatic congenital syphilis cases.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Congenital syphilis remains a challenge despite extensive experience.
- Issues persist in case definition, diagnosis, treatment, and follow-up for congenital syphilis.
Purpose of the Study:
- To review early congenital syphilis cases reported in Texas in 1982.
- To identify challenges in diagnosis, treatment, and follow-up.
- To assess potential under-reporting of asymptomatic cases.
Main Methods:
- Retrospective review of 50 early congenital syphilis cases reported in Texas in 1982.
- Analysis of infant characteristics, diagnostic findings, and treatment regimens.
Main Results:
- A significant proportion of infants were premature (39%), low birth weight (38%), and symptomatic at birth (62%).
- Over half of asymptomatic infants showed positive cerebrospinal fluid VDRL results.
- Treatment regimens for penicillin varied widely among the 47 living infants.
Conclusions:
- Asymptomatic congenital syphilis may be under-reported in Texas.
- Complete diagnostic evaluations are crucial for suspected cases.
- Standardized diagnostic and follow-up protocols are needed for congenital syphilis.
Abstract:
Despite decades of experience with congenital syphilis, problems still arise in case definition, diagnostic evaluation, treatment, and follow-up. We reviewed all 50 cases of early congenital syphilis reported to the State of Texas in 1982. A large proportion of the infants were premature (39%), of low birth weight (38%), and symptomatic at birth (62%). Because of these findings, we believe that possible cases of asymptomatic congenital syphilis in Texas may be under-reported. Laboratory and/or roentgenographic findings were important to confirm the diagnosis of congenital syphilis. Over half of the asymptomatic infants had positive results of cerebrospinal fluid VDRLs. After diagnosis, the treatment of infants with penicillin varied considerably. While all 47 living infants were treated with penicillin, 21 different regimens were used. We urge all physicians to perform complete diagnostic evaluations on suspected infants consisting of a quantitative serum test for syphilis, serum IgM levels, a cerebrospinal fluid VDRL, roentgenographs of the long bones, and dark-field microscopy where indicated. Additionally, infants and their families need appropriate follow-up after treatment.
