Congenital Syphilitic Meningitis: A Rare and Obsolete Condition

Congenital syphilitic meningitis is a rare and serious condition that occurs when the spirochete Treponema pallidum is transmitted from a pregnant individual to the fetus, resulting in inflammation of the meninges (the protective membranes surrounding the brain and spinal cord) [13]. This condition was once considered a major cause of fetal and neonatal mortality globally, but with advancements in medicine and preventive strategies, its incidence has significantly decreased.

Symptoms and Presentation

The symptoms of congenital syphilitic meningitis can vary widely, ranging from asymptomatic cases to severe manifestations such as acute syphilitic meningitis or chronic meningovascular syphilis [12]. Acute syphilitic meningitis typically presents early in the first year of life and is clinically indistinguishable from typical bacterial meningitis. Cerebrospinal fluid analysis may reveal abnormalities, but a definitive diagnosis can only be made through histological examination of the placenta and cord.

Prevention and Treatment

The prevention of congenital syphilitic meningitis lies in the early detection and treatment of syphilis in pregnant individuals [15]. Regular testing for syphilis during pregnancy is crucial to prevent serious health complications for both mother and baby. If left untreated, congenital syphilitic meningitis can lead to severe consequences, including stillbirth, prematurity, or a wide spectrum of clinical manifestations.

Current Status

With the advent of modern medicine and preventive strategies, congenital syphilitic meningitis is now considered an obsolete condition in many parts of the world. However, it remains a significant global burden in areas with limited access to healthcare resources [3]. The surveillance case definition for congenital syphilis has been established, and diagnostic algorithms are available to aid in the diagnosis of this condition.

[3] CS is a serious but preventable disease which can lead to fetal loss, stillbirth, neonatal death, and congenital infection. Based on the age when clinical manifestations occur, it can be divided into early (first 2 weeks of life), intermediate (2-12 months), and late (beyond 1 year) stages.

[13] Congenital syphilis occurs when the spirochete Treponema pallidum is transmitted from a pregnant individual to the fetus. Infection can result in stillbirth, prematurity, or a wide spectrum of clinical manifestations; only severe cases are clinically apparent at birth.

[15] If you are sexually active, have an open and honest conversation with your healthcare provider. Ask them if you should get tested for syphilis and other STIs. Get a syphilis test the first time you see a healthcare provider during pregnancy. Getting tested and treated for syphilis can prevent serious health complications for you and your baby.

Early Warning Signs and Symptoms

Congenital syphilis, when left untreated, can lead to severe complications, including syphilitic meningitis. While this condition is relatively rare, it's essential to be aware of the signs and symptoms that may indicate its presence.

• Meningitis: This infection causes swelling in the brain and spinal cord, leading to symptoms such as:
  • Seizures [8]
  • Disturbances of consciousness [8]
  • Cranial nerve palsies
  • Headaches
  • Vomiting
  • Dizziness
• Other Symptoms: In addition to meningitis, congenital syphilis can cause a range of other symptoms, including:
  • Jaundice
  • Low red blood cell count and low platelet count (thrombocytopenia)
  • Soft, wart-like lesions called condyloma lata

Important Notes

• Not all babies born with congenital syphilis will exhibit signs or symptoms at birth. However, if left untreated, the baby may develop serious problems later on.
• Early detection and treatment are crucial to prevent long-term morbidities in neonates.

Diagnostic Tests for Obsolete Congenital Syphilitic Meningitis

The diagnosis of congenital syphilitic meningitis, a condition that was once prevalent but is now considered obsolete due to advances in medicine and public health measures, can be challenging. However, several diagnostic tests were used in the past to diagnose this condition.

• Lumbar Puncture: The most important test to perform when meningitis is suspected is the lumbar puncture (result 4). This involves withdrawing a sample of cerebrospinal fluid from the lower back for analysis.
• Cerebrospinal Fluid Analysis: The cerebrospinal fluid should be tested for cell counts, protein levels, and glucose levels to confirm the presence of meningitis (result 4).
• Serological Tests: Serological tests such as the Venereal Disease Research Laboratory (VDRL) slide test and the rapid plasma reagin (RPR) test were used to detect antibodies against Treponema pallidum, the bacteria that causes syphilis (results 1, 2, and 6).
• Treponemal Tests: Treponemal tests such as the fluorescent treponemal antibody, absorbed (FTA-ABS) test were also used to detect antibodies against T. pallidum (results 5 and 9).

It's worth noting that these diagnostic tests are no longer commonly used today due to advances in medicine and public health measures. The diagnosis of congenital syphilitic meningitis is now typically made based on a combination of clinical findings, maternal history, and modern serological testing.

Treatment Options for Congenital Syphilis Meningitis

Historically, the treatment for congenital syphilis meningitis involved various medications, including:

• Aqueous crystalline penicillin G: This was considered a standard treatment for neurosyphilis, including syphilitic meningitis (4). The recommended dosage was 3-4 million units every 4 hours intravenously for 10-14 days.
• Procaine penicillin G: An alternative treatment option was procaine penicillin G, administered as a single daily dose of 50,000 units/kg intramuscularly for 10 days (7). No treatment failures were reported with this regimen.

Modern Treatment Approaches

While the exact treatment protocols may have evolved over time, it is essential to note that parenteral penicillin G remains an effective therapy for patients with neurosyphilis, congenital syphilis, or syphilis during pregnancy (2).

In contrast, benzathine penicillin G (BPG) does not appear to be a suitable treatment option for neurosyphilis, as it is less effective than aqueous crystalline penicillin G in this context (4).

Current Recommendations

The recommended treatment for late-stage syphilis, including syphilitic meningitis, involves three weekly intramuscular injections of 2.4 million units of benzathine penicillin G (3). However, it is crucial to note that the effectiveness and safety of this regimen may vary depending on individual circumstances.

Important Considerations

When treating congenital syphilis meningitis, it is essential to consider the potential long-term sequelae of untreated disease. Infants with congenital syphilis who receive timely treatment have a lower risk of long-term complications (5).

In contrast, untreated or inadequately treated congenital syphilis can lead to severe sequelae, including cerebral palsy, hydrocephalus, sensorineural hearing loss, and musculoskeletal deformity (15).

Based on the provided context, it appears that congenital syphilitic meningitis is a rare condition that was previously considered as a distinct entity. However, with advancements in medical knowledge and diagnostic techniques, its differential diagnosis has expanded to include other conditions.

The following are some of the obsolete or less commonly considered causes of congenital syphilitic meningitis:

• Congenital toxoplasmosis: This condition is caused by the Toxoplasma gondii parasite and can lead to neurological symptoms, including meningitis (8).
• Congenital rubella: Infection with the rubella virus during pregnancy can cause a range of congenital abnormalities, including neurological symptoms such as meningitis (9).
• Congenital cytomegalovirus: This is another viral infection that can cause congenital abnormalities and neurological symptoms, including meningitis (9).
• Congenital herpes infection: Infection with the herpes simplex virus during pregnancy can cause a range of congenital abnormalities, including neurological symptoms such as meningitis (9).

It's essential to note that these conditions are not directly related to syphilis but can present with similar symptoms. A comprehensive diagnostic workup is necessary to rule out these and other potential causes.
