About Tertiary Syphilis

Overview
Tertiary syphilis is a late stage of syphilis that occurs several years after the initial infection if left untreated. It is a rare complication nowadays due to the availability of penicillin as a treatment. Tertiary syphilis is associated with damage to various organ systems in the body, and it can even lead to death if not addressed. The affected systems can include joints, brain, eyes, nerves, bones, heart, liver, and blood vessels. It is important for individuals who are at higher risk of developing tertiary syphilis to get screened for the infection regularly. This includes bisexual or gay males, individuals living with HIV, partners of those who have tested positive for syphilis, individuals taking pre-exposure prophylaxis (PrEP) for HIV prevention, and pregnant individuals who may have been exposed to syphilis. Screening and early treatment can help prevent the progression to tertiary syphilis and its associated complications.
Causes and Risk Factors

Tertiary syphilis is a late stage of syphilis that can occur if the infection is left untreated. It is currently a rare complication due to the availability of penicillin, which is an antibiotic that effectively treats syphilis. However, if left untreated, syphilis can progress to the tertiary stage, which can cause damage to various organ systems and even lead to death.

The cause of tertiary syphilis is as follows:

  • It is primarily related to the presence of the bacteria treponema pallidum, which is responsible for causing syphilis.
  • When a person becomes infected with syphilis through sexual contact or other means, the bacteria can enter their body and spread throughout their system.
  • If the infection is not treated with antibiotics, the bacteria can continue to multiply and cause further damage over time.

There are both non-modifiable and modifiable risk factors associated with tertiary syphilis. Non-modifiable risk factors are factors that cannot be changed or controlled. These include:

  • Time since initial infection: Tertiary syphilis typically occurs between 10 to 30 years after the initial infection. This means that individuals who have had syphilis for a long time without receiving treatment are at a higher risk of developing tertiary syphilis.
  • Age: Tertiary syphilis can occur in individuals of any age, but it is more commonly seen in older adults who have had untreated syphilis for many years.

Modifiable risk factors are factors that can be changed or controlled. These include:

  • Access to healthcare: Individuals who do not have access to regular healthcare or who do not seek medical treatment for syphilis are at a higher risk of developing tertiary syphilis.
  • Treatment adherence: If a person receives treatment for syphilis but does not complete the full course of antibiotics as prescribed by their healthcare provider, it increases their risk of developing complications such as tertiary syphilis.

It's important to note that anyone who has had an untreated or partially treated syphilis infection is at risk of developing tertiary syphilis. Regular screening for syphilis is recommended for individuals who have a higher risk of developing complications, such as bisexual or gay males, those living with HIV, partners of those who tested positive for syphilis, those taking pre-exposure prophylaxis (PrEP) for HIV prevention, and pregnant individuals who may have been exposed to syphilis.

Symptoms

Tertiary syphilis is a stage of syphilis that occurs several years after the initial infection. The symptoms of tertiary syphilis can vary depending on which organs are affected. Here are common symptoms of tertiary syphilis:

  • Difficulty moving arms and legs/trouble with muscle movements
  • Numbness
  • Muscle weakness
  • Paralysis
  • Heart disease
  • Severe headache
  • Changes in mental state, such as trouble focusing, confusion, or personality change
  • Dementia, which can cause problems with memory, thinking, or decision making
  • Changes in vision or blindness; eye pain or redness in the eye
  • Ringing, hissing, buzzing, or roaring in the ears (tinnitus); or hearing loss
  • Dizziness or vertigo (feeling like you or your surroundings are moving or spinning)

It's important to note that most people with untreated syphilis do not develop tertiary syphilis. However, if it does occur, it can be very serious and may result in damage to internal organs and even death. If you suspect you have syphilis or are experiencing any symptoms, it's important to seek medical attention for diagnosis and treatment.

Diagnosis

To diagnose tertiary syphilis, healthcare providers may perform several examinations, tests, and procedures. These include:

  • Physical examination: A healthcare provider will conduct a physical examination to check for any visible signs of syphilis, such as skin rashes or sores.
  • Sexual history: The healthcare provider will ask about a person's sexual history to assess their risk of syphilis and other sexually transmitted infections (STIs).
  • Blood tests: Blood tests are commonly used to detect current or past syphilis infections. These tests can detect antibodies to the syphilis bacteria, which can remain present in the body for many years.
  • Fluid evaluation: If a person has active sores (chancre) during the primary or secondary stage of syphilis, a healthcare provider may collect fluid from the sore for evaluation.
  • Cerebrospinal fluid (CSF) examination: In cases where tertiary syphilis is suspected, a healthcare provider may perform a CSF examination through a spinal tap. This procedure involves collecting fluid from the spinal cord to assess the effects of syphilis on the nervous system.

Additional examinations, tests, and procedures may include:

  • HIV testing: Healthcare providers often recommend testing for HIV in individuals diagnosed with syphilis. This is because HIV and syphilis can coexist and have similar risk factors.
  • Other STI testing: Along with HIV testing, healthcare providers may also recommend testing for other STIs such as gonorrhea and chlamydia. This is because individuals with one STI are often at higher risk for acquiring others.
  • Neurosyphilis regimen: If a CSF examination reveals abnormalities in individuals with tertiary syphilis, they may be treated with a neurosyphilis regimen. This involves specific medications to address the effects of syphilis on the nervous system.
  • Infectious disease specialist consultation: Individuals with cardiovascular syphilis or certain cases of tertiary syphilis may require management in consultation with an infectious disease specialist.
Treatment Options

The goals of treatment for tertiary syphilis are to cure the infection, prevent further damage to organ systems, and improve overall health. There are several medication types, therapies, and health behavior changes recommended to achieve these treatment goals including:

  • Medications:
    • Benzathine penicillin G: This is the recommended treatment for tertiary syphilis. It is given as three doses of intramuscular injections spread out over three weeks, with one dose per week. This medication works by killing the bacteria that cause syphilis.
    • Doxycycline: For individuals who cannot take penicillin due to allergy or other reasons, oral doxycycline is recommended. It is taken twice daily for 30 days and helps to eliminate the infection.
    • Ceftriaxone: Another option for those who cannot take penicillin is Ceftriaxone, which is given as a once-daily injection for 10-14 days. It works similarly to penicillin by killing the bacteria.
  • Therapeutic procedures:
    • CSF examination: All individuals with tertiary syphilis should receive a cerebrospinal fluid (CSF) examination before starting therapy. This helps healthcare providers assess the extent of neurosyphilis (syphilis affecting the nervous system) and determine appropriate treatment options.
    • HIV test: It is recommended that individuals with tertiary syphilis also undergo an HIV test. If the test results are negative, they may be offered HIV PrEP (pre-exposure prophylaxis) to prevent HIV infection.
  • Self-care and health behavior changes:
    • Safe sexual practices: To prevent reinfection or further transmission of syphilis, individuals should use condoms or other barrier methods during sexual intercourse.
    • Monogamy or choosing partners without syphilis: Having sexual relations with only one partner who does not have syphilis can reduce the risk of infection.
    • Regular blood tests: People at risk of syphilis should consider getting regular blood tests to detect any new infections early on.

It's important to note that while treatment can stop the infection and kill the bacteria, it may not reverse any damage already caused by syphilis. Therefore, early detection and prompt treatment are crucial to preventing complications associated with tertiary syphilis. If you have any concerns or questions about treatment options, it's always best to discuss them with a healthcare provider who can provide personalized advice based on your specific situation.

Progression or Complications

Tertiary syphilis is a late stage of syphilis that can occur if the infection is not treated in the earlier stages. It usually develops 10-30 years after the initial infection.

When someone has tertiary syphilis, it can lead to damage in several organ systems and even death. The complications commonly associated with tertiary syphilis include:

  • Damage to internal organs: Tertiary syphilis can cause damage to organs such as the heart, liver, and blood vessels. This damage can have serious consequences for a person's overall health.
  • Changes in vision: Tertiary syphilis can affect the eyes and lead to vision problems. It is important for individuals with syphilis to monitor their vision and seek medical attention if they notice any changes.
  • Neurosyphilis: When syphilis spreads to the brain or nervous system, it is called neurosyphilis. This can result in symptoms such as headaches, difficulty moving parts of the body, numbness, and even dementia.

It's crucial to seek medical treatment for syphilis as soon as possible to prevent the development of tertiary syphilis and its complications. Treatment with antibiotics can cure the infection and help slow down or reduce the progression of tertiary syphilis. The earlier treatment is initiated, the easier it is to cure the infection.
