This condition arises from the progression of untreated syphilis, leading to neurological complications. The treatment for neurosyphilis is critical to prevent further neurological damage and to manage symptoms effectively.

Standard Treatment Approaches

1. Antibiotic Therapy

The cornerstone of treatment for neurosyphilis is the administration of antibiotics, primarily penicillin. The recommended regimen typically includes:

• Aqueous crystalline penicillin G: Administered intravenously (IV) at a dose of 18-24 million units per day, divided into doses every 4 hours, for 10 to 14 days. This is the most effective treatment for neurosyphilis and is considered the standard of care[1][2].

2. Alternative Antibiotics

For patients who are allergic to penicillin, alternative antibiotics may be considered, although they are generally less effective. Options include:

• Doxycycline: 100 mg orally twice daily for 28 days, though this is not as commonly used as penicillin.
• Ceftriaxone: 2 g IV daily for 14 days may be used in certain cases, particularly for those with severe penicillin allergies[1].

3. Symptomatic Management

In addition to antibiotic therapy, managing symptoms associated with neurosyphilis is essential. This may include:

• Pain management: Analgesics may be prescribed to alleviate headaches or other pain symptoms.
• Psychiatric support: Patients may require psychiatric evaluation and treatment for neuropsychiatric symptoms, which can include depression or cognitive dysfunction.
• Rehabilitation services: Physical therapy or occupational therapy may be beneficial for patients experiencing motor deficits or functional impairments[2].

4. Monitoring and Follow-Up

Regular follow-up is crucial to assess treatment efficacy and monitor for potential complications. This typically involves:

• Serological testing: To evaluate the response to treatment, including monitoring the decline of non-treponemal tests (e.g., RPR or VDRL) and treponemal tests.
• Neurological assessments: Follow-up neurological examinations to monitor for improvement or progression of symptoms[1][2].

Conclusion

The treatment of other symptomatic neurosyphilis (ICD-10 code A52.19) primarily revolves around the use of intravenous penicillin G, with careful management of symptoms and regular monitoring. Early diagnosis and treatment are vital to prevent irreversible neurological damage and improve patient outcomes. For those with penicillin allergies, alternative antibiotics can be considered, but they may not be as effective. Continuous follow-up is essential to ensure the success of the treatment regimen and to address any emerging complications.
