early congenital syphilis

Early congenital syphilis, also known as early onset congenital syphilis, typically presents in infants before the age of 2 years. The symptoms can vary widely and may include:

• Fever
• Skin problems, such as rashes or inflammation
• Low birth weight
• Failure to gain weight or thrive
• Enlarged liver and/or spleen (mass in belly)

These symptoms can occur at birth or within the first few weeks of life. In some cases, infants with early congen

Early Congenital Syphilis Signs and Symptoms

Early congenital syphilis can manifest in infants born to mothers with untreated or inadequately treated syphilis infection during pregnancy. The symptoms can be subtle and may not always be immediately apparent.

• Fever: One of the earliest signs of early congenital syphilis is fever, which can occur shortly after birth [3].
• Skin problems: Infants with early congenital syphilis may experience skin problems such as rashes or sores on their hands and feet [2].
• Low birth weight: Babies born to mothers with untreated syphilis infection during pregnancy are more likely to have low birth weight [1].

It's essential for healthcare providers to be aware of these symptoms and perform thorough examinations to diagnose early congenital syphilis promptly. Early detection and treatment can significantly improve the infant's outcome.

Early Congenital Syphilis Diagnostic Tests

Early congenital syphilis can be challenging to diagnose due to the presence of maternal antibodies in newborns. However, several diagnostic tests can help identify this condition.

• Nontreponemal tests: These tests detect antibody to cardiolipin and include the Venereal Disease Research Laboratory (VDRL) or Rapid Plasma Reagin (RPR) tests [2]. While these tests are not specific for syphilis, they can be used as a screening tool.
• Treponemal tests: These tests detect antibodies against Treponema pallidum and include the Fluorescent Treponemal Antibody Absorption (FTA-ABS) test and the Treponema Pallidum Particle Agglutination (TPPA) test [7]. These tests are more specific for syphilis but can remain positive for life, even after treatment.
• IHC ABC technique or IIF: These tests can be used to detect antibodies against Treponema pallidum in placenta and umbilical cord samples [3].
• Darkfield examination: This test can help diagnose early congenital syphilis by examining skin lesions and sometimes placenta and umbilical cord samples for the presence of Treponema pallidum [13].

Additional Tests

In addition to these diagnostic tests, healthcare providers may also perform other tests to confirm the diagnosis of early congenital syphilis. These can include:

• Physical examination: A thorough physical examination of the infant may show signs of liver and spleen swelling and bone inflammation [5].
• Blood tests: Blood tests can be used to detect antibodies against Treponema pallidum in both the mother and child [4, 14].

Treatment Options for Early Congenital Syphilis

Early congenital syphilis, a condition that occurs when a baby is born with syphilis, requires prompt and effective treatment to prevent serious complications. The primary goal of treatment is to eliminate the infection and prevent long-term damage.

• Penicillin remains the drug of choice: According to recent guidelines [2], penicillin remains the preferred treatment for all stages of syphilis, including early congenital syphilis. No evidence suggests an increasing penicillin resistance.
• Benzathine penicillin G is recommended: In infants with possible syphilis whose mothers were adequately treated and who are clinically well, a single dose of benzathine penicillin 50,000 units/kg body weight can be administered [3].
• Aqueous crystalline penicillin G for severe cases: For more severe cases or those requiring hospitalization, aqueous crystalline penicillin G 100,000–150,000 units/kg body weight/day, administered as 50,000 units/kg body weight/dose by IV every 12 hours during the first two weeks of life, may be necessary [4].
• WHO STI guideline recommendations: In adults and adolescents with early syphilis, the WHO STI guideline recommends benzathine penicillin G 2.4 million units once intramuscularly over no treatment [5].

Key Takeaways

• Penicillin is the primary treatment for early congenital syphilis.
• Benzathine penicillin G is recommended for mild cases, while aqueous crystalline penicillin G may be necessary for more severe cases.
• Treatment should be initiated promptly to prevent long-term damage and complications.

Early Congenital Syphilis Differential Diagnosis

The differential diagnosis for early congenital syphilis involves a range of conditions that can present with similar symptoms to the disease. These include:

• Congenital Rubella: A viral infection caused by the rubella virus, which can cause similar symptoms to congenital syphilis, including skin lesions and lymphadenopathy [5].
• Cytomegalovirus Infection: A viral infection that can cause a range of symptoms, including skin lesions, hepatosplenomegaly, and failure to thrive [6].
• Toxoplasmosis: A parasitic infection caused by the Toxoplasma gondii parasite, which can cause similar symptoms to congenital syphilis, including skin lesions and lymphadenopathy [7].
• Bacterial Sepsis: A life-threatening condition caused by a bacterial infection, which can present with similar symptoms to congenital syphilis, including fever, rash, and organ dysfunction [8].

It's essential to consider these conditions in the differential diagnosis of early congenital syphilis, as they can have overlapping symptoms and require different treatment approaches.
