how does having hiv affect the treatment for neurosyphilis

Treponema pallidum

interacts with HIV in a way that makes it harder to treat the syphilis infection. Those with neurosyphilis and HIV usually need more penicillin injections and have a lower chance for complete recovery. Long-term outlook Your long-term outlook depends on what type of neurosyphilis you have and how early your doctor diagnoses it.

Full Answer

Is there a link between syphilis and HIV?

The genital ulcers caused by syphilis can bleed easily, and when they come into contact with oral and rectal mucosa during sex, increase the infectiousness of and susceptibility to HIV. Studies have observed that infection with syphilis was associated with subsequent HIV infection among MSM.

What are the signs and symptoms of neurosyphilis?

Symptoms usually affect the nervous system. Depending on the form of neurosyphilis, symptoms may include any of the following: Abnormal walk (gait), or unable to walk; Numbness in the toes, feet, or legs

Does syphilis increase the risk of HIV transmission?

Syphilis can also be transmitted from a mother to her child during pregnancy. Syphilis sores (chancres) occur mainly on the genitals, anus, and rectum, but also on the lips and mouth. Genital sores caused by syphilis increase the risk of sexual transmission of HIV.

How long until syphilis turn into neurosyphilis?

How long does it take for syphilis to turn into neurosyphilis? Neurosyphilis usually occurs about 10 to 20 years after a person is first infected with syphilis. Not everyone who has syphilis develops this complication.

Is neurosyphilis related to HIV?

Neurosyphilis is an important component of central nervous system (CNS) diseases in HIV-infected patients. However, the characteristics of NS in HIV-infected patients are not very clear. There were studies showing that concomitant uveitis and asymptomatic NS (ANS) may be more common in HIV-infected persons.

What happens with syphilis and HIV?

Syphilis and HIV coinfection is particularly prevalent in MSM. Having syphilis can increase a person's risk of contracting HIV. In those with HIV, syphilis may progress faster and be harder to treat, although these effects are more common in people with high viral load and low CD4 count.

What is the recommended treatment for syphilis in a patient with HIV?

Penicillin G remains the treatment of choice for syphilis. Persons with HIV infection with early-stage (e.g., primary, secondary, or early-latent) syphilis should receive a single intramuscular (IM) injection of 2.4 million Units (U) of benzathine penicillin G (AII).

What is the treatment for neurosyphilis?

Individuals with neurosyphilis can be treated with penicillin given by vein, or by daily intramuscular injections for 10 – 14 days. If they are treated with daily penicillin injections, individuals must also take probenecid by mouth four times a day.

What are the symptoms of neurosyphilis?

SymptomsAbnormal walk (gait), or unable to walk.Numbness in the toes, feet, or legs.Problems with thinking, such as confusion or poor concentration.Mental problems, such as depression or irritability.Headache, seizures, or stiff neck.Loss of bladder control (incontinence)Tremors, or weakness.More items...•

What if syphilis treatment fails?

While syphilis could lead serious complications when left untreated, it is simple to cure with the appropriate treatment at early stages [2]. Having syphilis once does not protect patients from getting the disease again. Even after successful treatment, patients might still be re-infected by unprotected sexual contact.

Can neurosyphilis be cured?

If you aren't treated for secondary syphilis, the disease will likely progress to the latent stage, and may even progress to the tertiary stage. The secondary stage of syphilis is curable with medical treatment.

Can a blood test detect neurosyphilis?

As evidenced, neurosyphilis is not a rare disease, but its diagnosis may be very elusive. However, it is easy to rule out this diagnosis using blood tests.

Does penicillin treat neurosyphilis?

The US Centers for Disease Control and Prevention (CDC) has recommended that neurosyphilis be treated with 18–24 million units of intravenous (IV) aqueous penicillin G (PenG) for 10–14 days.

What is neurosyphilis in the brain?

Neurosyphilis is a broad term used to describe the direct invasion of T. pallidum into the nervous system and can affect the brain, spinal cord and peripheral nerves. 7 Approximately 25%–40% of patients have ‘neuroinvasion’ at some point, typically during the primary or secondary stage of infection, but most spontaneously clear the infection from the cerebrospinal fluid (CSF) without requiring treatment for neurosyphilis and potentially without having any symptoms. 8 In patients whose immune system cannot clear the infection, neurosyphilis develops; this can also present with or without symptoms, the latter form known as asymptomatic neurosyphilis. 7 There is great debate around the topic of asymptomatic neurosyphilis (discussed below).

How does syphilis affect the eyes?

Conceivably the most well remembered ocular manifestation is Argyll Robertson pupils, which accommodate but do not react to light and thus demonstrate light–near dissociation. This finding is highly specific for syphilis but can also occur in diabetic neuropathy or as part of a dorsal midbrain syndrome. Anterior or posterior uveitis is perhaps the most common, but papillary conjunctivitis, scleritis, neuroretinitis and retinal vasculitis also occur, usually in secondary and tertiary stages. Furthermore, syphilis is on the important list of differential diagnoses for presentations of progressive optic neuropathy, and thus should be excluded in patients whose optic neuritis is ‘atypical’. Ocular syphilis appears to be a type of neurosyphilis, although it is not always accompanied by syphilitic meningitis or abnormal CSF results. However, given that the recommended treatment is the same neuropenetrative regimen used for neurosyphilis, 48 it may not be necessary to perform CSF analysis in every case.

How long does it take for syphilis to develop?

Primary syphilis classically presents 9–90 days after infection with a single, non-tender genital ulcer (chancre) representing the first site of T. pallidum invasion. If untreated, the primary infection progresses to secondary syphilis, typically 12 weeks, but sometimes up to 12 months after initial infection.

What is the CSF VDRL?

The CSF VDRL is the ‘gold standard’ in terms of specificity for neurosyphilis but has significant limitations; its variable sensitivity (30%–70%)%) means a non-reactive CSF VDRL does not exclude the diagnosis of neurosyphilis.

How to diagnose genital syphilis?

Genital syphilis can be diagnosed by swabbing a chancre and performing dark-ground microscopy, which shows the presence of T. pallidum. 5 This technique is still used in genitourinary medicine clinics and can be used on samples obtained from biopsies, including in suspected cases of neurosyphilis.

Is neurosyphilis a differential diagnosis?

Neurosyphilis should be a differential diagnosis for any HIV-positive patient presenting with unexplained neurological symptoms, as listed in box 3. Challenges arise due to the overlap of neurological manifestations caused by both organisms and the numerous pathologies that can develop in advanced HIV infection.

Can neurosyphilis be asymptomatic?

Progression to neurosyphilis is more common in HIV coinfection and can be asymptomatic, often for several years. The presentations of neurosyphilis vary but can include meningitis, meningovascular disease, general paresis and tabes dorsalis.

What is the risk of developing neurosyphilis?

There was a major increase in syphilis cases during the 2000s, especially among women ages 20 to 24 and men ages 35 to 39. If syphilis goes untreated, the affected person is at risk of developing neurosyphilis. This is an infection of the nervous system, specifically of the brain and the spinal cord. Neurosyphilis is a life-threatening disease.

Why is neurosyphilis so common?

Neurosyphilis is especially common in people who have HIV. This is because syphilitic sores make it easier to become infected with HIV. Treponema pallidum interacts with HIV in a way that makes it harder to treat the syphilis infection.

How long does it take for neurosyphilis to develop?

Neurosyphilis tends to develop about 10 to 20 years after the initial infection with the bacterium. Having HIV and untreated syphilis are major risk factors for neurosyphilis.

How long does it take for penicillin to work for neurosyphilis?

The antibiotic penicillin is used to treat syphilis and neurosyphilis. It may be injected or taken orally. The usual regimen lasts 10 to 14 days. The antibiotics probenecid and ceftriaxone are often used along with penicillin.

How many strokes are there with neurosyphilis?

This is a more serious form of meningeal neurosyphilis. In this case, you would also have had at least one stroke. About 10 to 12 percent of those with neurosyphilis develop this form. A stroke may occur in the first few months following a syphilis infection, or it may happen a few years after infection.

What is the most common type of neurosyphilis?

Asymptomatic neurosyphilis. This is the most common type of neurosyphilis. It usually occurs before the symptoms from syphilis become visible. In this form of neurosyphilis, you won’t feel sick or experience any signs of neurologic disease.

Why is it rare to get syphilis?

However, it’s fairly rare today because of advances in the screening, treatment, and prevention of STIs.

PURPOSE

To evaluate and describe the neuroimaging findings of patients with neurosyphilis.

METHODS

The neuroimaging studies of 35 patients with documented neurosyphilis were reviewed. Diagnosis was established in 34 patients with cerebrospinal fluid for a Venereal Disease Research Laboratory test, complemented by autopsy in 1 and brain biopsy in 1. All patients had reactive fluorescent treponemal antibody tests with absorption in their sera.

RESULTS

Of the 35 patients with imaging studies, 32 tested human immunodeficiency virus (HIV)-seropositive, and 3 were HIV-seronegative. Eleven (31%) of 35 patients had normal radiographic findings. Cerebral infarctions were seen in 8 (23%) of 35 patients, and nonspecific white matter lesions in 7 (20%) of 35.

CONCLUSION

We conclude that findings of vascular occlusive disease manifested as infarction or arteritis, enhancing cortical lesions with or without adjacent meningeal enhancement, focal or diffuse extraaxial enhancement, and white matter disease, although nonspecific, in the proper clinical setting should prompt appropriate testing for neurosyphilis, a treatable disease, in patients with and without HIV infection..

Do you have to be tested for HIV if you have ocular syphilis?

All persons who have neurosyphilis, ocular syphilis, or otosyphilis should be tested for HIV at the time of diagnosis. Those whose HIV test results are negative should be offered HIV PrEP.

Can CNS involvement occur in early syphilis?

CNS involvement can occur during any stage of syphilis, and CSF laboratory abnormalities are common among persons with early syphilis, even in the absence of clinical neurologic findings. No evidence exists to support variation from recommended diagnosis and treatment for syphilis at any stage for persons without clinical neurologic findings, except tertiary syphilis. If clinical evidence of neurologic involvement is observed (e.g., cognitive dysfunction, motor or sensory deficits, cranial nerve palsies, or symptoms or signs of meningitis or stroke), a CSF examination should be performed before treatment.

Can syphilis be a neurosyphilis?

Syphilitic uveitis or other ocular syphilis manifestations (e.g., neuroretinitis and optic neuritis) can occur at any stage of syphilis and can be isolated abnormalities or associated with neurosyphilis. All persons with ocular symptoms and reactive syphilis serology need a full ocular examination, including cranial nerve evaluation. If cranial nerve dysfunction is present, a CSF evaluation is needed. Among persons with isolated ocular symptoms (no cranial nerve dysfunction or other neurologic abnormalities), reactive syphilis serology, and confirmed ocular abnormalities on examination, CSF examination is unnecessary before treatment. CSF analysis might be helpful in evaluating persons with ocular symptoms and reactive syphilis serology who do not have ocular findings on examination. If ocular syphilis is suspected, immediate referral to and management in collaboration with an ophthalmologist is crucial. Ocular syphilis should be treated similarly to neurosyphilis, even if a CSF examination is normal.

Is a CSF examination necessary for HIV?

Therefore, repeated CSF examinations are unnecessary for persons without HIV infection or persons with HIV infection who are on ART and who exhibit serologic and clinical responses after treatment .

Can syphilis cause hearing loss?

Hearing loss and other otologic symptoms can occur at any stage of syphilis and can be isolated abnormalities or associated with neurosyphilis, especially of cranial nerve 8. However, among persons with isolated auditory symptoms, normal neurologic examination, and reactive syphilis serology, CSF examination is likely to be normal and is not recommended before treatment. Otosyphilis should be managed in collaboration with an otolaryngologist and treated by using the same regimen as for neurosyphilis.
