Syphilitic aseptic meningitis
Meningitis - syphilitic; Neurosyphilis - syphilitic meningitis
Syphilitic aseptic meningitis, or syphilitic meningitis, is a complication of untreated syphilis . It involves inflammation of the tissues covering the brain and spinal cord.
Syphilis
Syphilis is a bacterial infection that is most often spread through sexual contact.
Causes
Syphilitic meningitis is a form of neurosyphilis . This condition is a life-threatening complication of syphilis infection. Syphilis is a sexually transmitted infection.
Neurosyphilis
Neurosyphilis is a bacterial infection of the brain or spinal cord. It usually occurs in people who have had untreated syphilis for many years....
Syphilitic meningitis is similar to meningitis caused by other germs (organisms).
Meningitis
Meningitis is an infection of the membranes covering the brain and spinal cord. This covering is called the meninges.
Risks for syphilitic meningitis include a past infection with syphilis or other sexually transmitted illnesses such as gonorrhea . Syphilis infections are mainly spread through sex with an infected person. Sometimes, they may be passed by nonsexual contact.
Gonorrhea
Gonorrhea is a common sexually transmitted infection (STI).
Symptoms
Symptoms of syphilitic meningitis may include:
-
Changes in vision
, such as blurred vision, decreased vision

- Fever

- Nausea and vomiting
- Stiff neck or shoulders, muscle aches
-
Seizures

- Sensitivity to light ( photophobia ) and loud noises
-
Sleepiness,
lethargy
, hard to wake up
Lethargy
Fatigue is a feeling of weariness, tiredness, or lack of energy.
Exams and Tests
The health care provider will perform a physical exam. This may show problems with the nerves, including nerves that control eye movement.
Tests may include:
-
Cerebral angiography
to check blood flow in the brain
Cerebral angiography
Cerebral angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through the brain.
-
Electroencephalogram (
EEG
) to measure electrical activity in the brain
EEG
An electroencephalogram is a test to measure the electrical activity of the brain.
-
Head CT scan
Head CT scan
A head computed tomography (CT) scan uses many x-rays to create pictures of the head, including the skull, brain, eye sockets, and sinuses.
-
Spinal tap to remove a sample of
cerebrospinal fluid (CSF)
for examination
Cerebrospinal fluid (CSF)
The CSF-VDRL test is used to help diagnose neurosyphilis. It looks for substances called antibodies, which are sometimes produced by the body in rea...
-
VDRL blood test
or
RPR blood test
to screen for a syphilis infection
VDRL blood test
The VDRL test is a screening test for syphilis. It measures substances (proteins), called antibodies, that your body may produce if you have come in...
RPR blood test
RPR (rapid plasma reagin) is a screening test for syphilis. It looks for antibodies that are present in the blood of people who may have the disease...
If screening tests show a syphilis infection, more tests are done to confirm the diagnosis. Tests include:
-
FTA-ABS
FTA-ABS
The FTA-ABS test is a blood test to detect antibodies to the bacteria Treponema pallidum, which causes syphilis.
- MHA-TP
- TP-PA
- TP-EIA
Treatment
The goals of treatment are to cure the infection and stop symptoms from getting worse. Treating the infection helps prevent new nerve damage and may reduce symptoms. Treatment does not reverse existing damage.
Medicines likely to be given include:
- Penicillin or other antibiotics (such as tetracycline or erythromycin) for a long time to make sure the infection goes away
- Medicines for seizures
Outlook (Prognosis)
Some people may need help eating, dressing, and caring for themselves. Confusion and other mental changes may either improve or continue long-term after antibiotic treatment.
Late-stage syphilis can cause nerve or heart damage. This can lead to disability and death.
Possible Complications
Complications may include:
- Inability to care for self
- Inability to communicate or interact
- Seizures that may result in injury
- Stroke
When to Contact a Medical Professional
Go to the emergency room or call the local emergency number (such as 911) if you have seizures.
Call your provider if you have a severe headache with fever or other symptoms, especially if you have a history of syphilis infection.
Prevention
Proper treatment and follow-up of syphilis infections will reduce the risk of developing this type of meningitis.
If you are sexually active, practice safer sex and always use condoms.
All pregnant women should be screened for syphilis .
