Congenital Syphilis is a condition caused by the transmission of the bacterium Treponema pallidum from an infected mother to her unborn child during pregnancy. The infection can be transmitted at any stage of pregnancy and can have serious consequences for the infant if left untreated.
Congenital Syphilis can be transmitted through the placenta from an infected mother to her developing fetus. It can also occur during childbirth if the mother has an active syphilis infection.
The risk of transmission is higher if the mother has untreated or inadequately treated syphilis during pregnancy. Other factors that increase the risk include primary or secondary syphilis in the mother, a high concentration of bacteria in the mother’s blood, and a prolonged duration of infection before pregnancy.
Epidemiology
Congenital syphilis varies across different regions. Low- and middle-income countries bear a substantial proportion of the global burden of congenital syphilis. In these regions, limited access to antenatal care, syphilis screening, and effective treatment contribute to the high incidence rates.
Congenital syphilis remains a significant health problem worldwide. There were approximately 661,000 cases of maternal syphilis, resulting in over 205,000 adverse birth outcomes, including stillbirths, neonatal deaths, and congenital syphilis cases.
The rates of vertical transmission of syphilis from an infected mother to her fetus vary depending on several factors, including the stage of maternal syphilis and adequacy of antenatal care.
Anatomy
Pathophysiology
The route of transmission is through the placenta, allowing the spirochete bacterium to enter fetal circulation. The transmission can occur at any stage of pregnancy, but the risk of transmission is highest during the early stages of syphilis.
Once the bacterium crosses the placenta, it can infect various fetal tissues and organs. Treponema pallidum has a particular affinity for rapidly dividing cells, leading to its involvement in multiple organ systems, including the liver, spleen, bone marrow, skin, eyes, and central nervous system.
The inflammatory response leads to vasculitis, which is the inflammation of blood vessels. Vasculitis can cause damage to the vessel walls, impairing blood flow and disrupting the normal functioning of affected tissues and organs.
Etiology
Fritz Schaudinn and Erich Hoffmann discovered the syphilis-causing bacterium for the first time in 1905. Congenital syphilis is caused by Treponema pallidum, a motile spirochete, a helically wound, corkscrew-shaped bacterium that measures 6 to 15 mm in length and 0.1 to 0.2 mm in width.
Maternal syphilis can occur at any stage of the disease, including primary, secondary, latent, or tertiary syphilis. The transmission can also occur during childbirth if the mother has an active syphilis infection at the time of delivery.
Genetics
Prognostic Factors
The stage of maternal syphilis at the time of pregnancy can influence the prognosis. Infants born to mothers with early-stage syphilis (primary and secondary) have a higher risk of adverse outcomes compared to those born to mothers with late-stage syphilis.
The level of prenatal care received by the mother plays a significant role in the prognosis of congenital syphilis. Adequate and timely prenatal care allows for early detection and treatment of maternal syphilis, reducing the risk of transmission and improving outcomes for the infant.
The duration of maternal syphilis infection before pregnancy can impact the severity and complications of congenital syphilis.
Clinical History
Age Group:
Congenital syphilis mainly affects infants and newborns. The age group most associated with congenital syphilis includes:
Congenital syphilis can be present at birth or develop shortly after birth. Infants are typically diagnosed with congenital syphilis within the first few weeks to months of life.
Associated Comorbidity or Activity:
Low weight at time of birth: Infants born with congenital syphilis may have low birth weight, which can lead to various health issues.
Prematurity: Congenital syphilis can increase the risk of premature birth, with associated complications related to prematurity.
Anemia: Infants with congenital syphilis may develop anemia, which is a deficiency of red blood cells or hemoglobin.
Mucocutaneous lesions: Congenital syphilis can present with characteristic skin lesions, such as rash, blisters, and sores, affecting various parts of the body.
Physical Examination
Skin examination: The skin is carefully examined for any characteristic lesions or rashes. Congenital syphilis can present with maculopapular rash, vesicular lesions, bullous eruptions.
Mucous membrane examination: The oral cavity, including the lips, tongue, and palate, is examined for any mucous patches, which are whitish-gray patches or ulcerations that can occur in congenital syphilis.
Lymph nodes: The lymph nodes are palpated to assess for any enlargement or tenderness. Lymphadenopathy, particularly in the posterior cervical or generalized lymph node regions, can be observed in congenital syphilis.
Bone and joint examination: The bones and joints are assessed for any abnormalities, such as swelling, tenderness, or deformities. Congenital syphilis can cause osteochondritis and skeletal abnormalities, including periostitis and long bone abnormalities.

Associated activity
Acuity of presentation
Early onset: In some cases, infants with congenital syphilis may present with clinical signs and symptoms shortly after birth or within the first few weeks of life. These early-onset manifestations can include characteristic skin rashes (such as maculopapular rash), hepatosplenomegaly (enlarged liver and spleen), jaundice (yellowing of the skin and eyes), bone abnormalities, failure to thrive, and respiratory distress.
Late onset: In other cases, infants with congenital syphilis may initially appear asymptomatic at birth or have mild, nonspecific symptoms. These late-onset manifestations can include neurologic complications such as developmental delays, seizures, and hearing loss, dental abnormalities, skeletal abnormalities, and eye problems.
Differential Diagnoses
Various non-infectious conditions can cause skin rashes in newborns, such as drug reactions, erythema toxicum neonatorum, transient neonatal pustular melanosis, and staphylococcal scalded skin syndrome.
Certain genetic or metabolic disorders, such as hypothyroidism, phenylketonuria, or other inherited disorders, can present with clinical features that overlap with congenital syphilis.
Congenital syphilis may present similarly to other disease processes which should also be considered by the clinician. These include neonatal sepsis especially given the pneumonia-like chest x-ray findings in Congenital syphilis.

Treatment Paradigm
The treatment paradigm for congenital syphilis typically involves a combination of antibiotic therapy and careful monitoring of the affected infant.
Penicillin therapy: Intravenous or intramuscular penicillin G is the preferred antibiotic for treating congenital syphilis. The dosage and duration of treatment vary depending on the stage of the disease. For infants with early-stage syphilis within the first 2 years of life, a course of intravenous penicillin G for 10 days is typically recommended. Antibiotic therapy: The primary treatment for congenital syphilis is with antibiotics, usually penicillin. The specific antibiotic regimen and duration of treatment depend on the stage and severity of the disease.
Safe and clear-living conditions: Providing a safe and clear living environment is essential for the overall well-being of the infant. This includes ensuring access to clean water, proper sanitation facilities, and hygienic conditions to prevent the spread of infection. Supportive care: Infants with congenital syphilis may require specialized nutrition and supportive care to aid their recovery and promote healthy development. Adequate nutrition, including breastfeeding or appropriate formula feeding, is crucial for their growth and immune system support. Development of stimulation: Infants with congenital syphilis may experience developmental delays or neurological complications. Providing a stimulating environment that encourages age-appropriate play, social interaction, and sensory stimulation can aid in their cognitive and motor development.
Use of Penicillin therapies to treat congenital syphilis
Penicillin G is the preferred and most effective antibiotic for treating congenital syphilis. It is typically administered intravenously or intramuscularly. The dosage and duration of treatment depend on the stage and severity of the disease. In some cases, where intravenous administration is not feasible, oral penicillin may be considered.
In <1 month of age: Single-dose regimen, long-acting benzathine penicillin G is used. Penicillin’s minimum inhibitory concentration (MIC) is approximately 0.0005 mcg/mL.
The cerebrospinal fluid (CSF) must remain at a concentration of 0.018 mcg/mL for seven to ten days in order to effectively treat neurosyphilis.
Use of antibiotic drugs
In cases where the patient has a known penicillin allergy, alternative antibiotics may be used. These alternatives include ceftriaxone or azithromycin, although they may not be as effective as penicillin for all stages of syphilis.
Ceftriaxone: In cases where the patient has a known penicillin allergy, ceftriaxone can be an alternative antibiotic. It is administered intravenously or intramuscularly.
ceftriaxone may not be as effective as penicillin for all stages of syphilis, and the decision to use it should be made in consultation with an infectious disease specialist.
Azithromycin: It is typically given orally. It is not as effective as penicillin for treating congenital syphilis and is generally reserved for situations where other options are not available.
Radiographic imaging: X-rays, ultrasound, or other imaging techniques may be utilized to evaluate specific manifestations of congenital syphilis. For example, imaging may be used to assess skeletal abnormalities or evaluate the progression of bone lesions. Ophthalmologic examination: Congenital syphilis can cause eye abnormalities such as interstitial keratitis or uveitis. An ophthalmologic examination may be performed to assess the extent of ocular involvement and guide appropriate treatment, which may include topical or systemic medications.

Initial Diagnosis: The first phase involves diagnosing congenital syphilis. This includes screening pregnant women for syphilis during prenatal care and performing diagnostic tests on infants born to mothers with syphilis. Antibiotic treatment: Once the diagnosis of congenital syphilis is confirmed, the next phase involves initiating antibiotic treatment. The choice of antibiotic and the duration of treatment depend on the stage and severity of the disease. Regular follow-ups: After initiating antibiotic treatment, regular monitoring and follow-up are essential to evaluate the infant’s response to treatment and assess for any potential complications or relapse.
