Syphilis treatment journey in older adults

Overview

Syphilis is a bacterial infection that is usually passed from one person to another through sexual contact. It can also be passed from a pregnant person to their baby. If left untreated, it can cause serious health problems over many years, but it is completely curable with the right antibiotics.

Syphilis is less common than some other infections, but cases have been rising in many countries, including among older adults. It is still considered a treatable and preventable condition.

Anyone who is sexually active can get syphilis. Older adults are at risk just like younger people, especially if they have new or multiple sexual partners without using condoms.

Symptoms

Common symptoms

• Primary stage: one or more painless sores (called chancres) on the genitals, mouth, or rectum. The sore heals on its own after a few weeks.
• Secondary stage: a rash that does not itch, often on the palms of the hands and soles of the feet. Other symptoms may include fever, sore throat, tiredness, and swollen glands.
• Latent stage: no visible symptoms, but the bacteria remain in the body.
• Tertiary stage: serious damage to the heart, brain, nerves, or other organs, sometimes many years after the initial infection.

Symptoms in older adults

• Symptoms may be very mild or different from the usual stages. For example, the initial sore may be inside the mouth or rectum and go unnoticed.
• Older adults may have a rash that is mistaken for other skin conditions, or they may have no rash at all.
• Neurological symptoms like confusion, memory problems, or difficulty walking can appear in late-stage syphilis and be confused with aging or dementia.

Causes

Main causes

• Syphilis is caused by a bacteria called Treponema pallidum. It is usually spread through direct contact with a syphilis sore during vaginal, anal, or oral sex.

Risk factors

• Having unprotected sex with a new or multiple partners
• Having a partner who tests positive for syphilis
• Men who have sex with men are at higher risk
• Living with HIV or another sexually transmitted infection
• Not using condoms consistently

When to see a doctor

See a doctor urgently if:

• If you have any symptoms of syphilis, such as a painless sore on your genitals or a rash on your palms or soles.
• If you know you have been exposed to someone with syphilis, even if you have no symptoms.
• If you have any neurological symptoms like confusion, vision changes, or trouble walking.

Book a routine appointment if:

• If you are sexually active and think you might be at risk, you can ask your doctor about routine testing for syphilis and other sexually transmitted infections.
• If you are pregnant, syphilis testing is a routine part of prenatal care.

Diagnosis

Your doctor will ask about your symptoms and any possible exposure. They will also take a small sample of blood or fluid from a sore to test for the bacteria.

Tests that may be done

• Blood test: This is the most common way to check for syphilis antibodies.
• Dark-field microscopy: If you have a sore, your doctor may look at fluid from the sore under a microscope to see the bacteria.
• Lumbar puncture (spinal tap): If the infection has spread to the nervous system, your doctor may test the fluid around your spine.

What to expect at your appointment

The tests are usually quick and simple. A blood test takes just a few minutes. If you need a spinal tap, you will be given a local anesthetic to numb the area. Your doctor will explain the results and start treatment as soon as possible.

Treatment

Syphilis is treated with antibiotics, usually given as an injection (shot) into a muscle. The type and length of treatment depend on the stage of the infection. In most cases, a single injection is enough for early syphilis. For later stages or if the infection has spread to the brain, a longer course of antibiotics may be needed. It is important to finish all the treatment exactly as prescribed, even if you feel better. After treatment, you will need follow-up blood tests to make sure the infection is gone.

Self-care at home

• Avoid all sexual contact until your doctor tells you the infection is cured (usually after follow-up blood tests show it is gone).
• Tell your current and recent sexual partners so they can get tested and treated.
• Take all antibiotics exactly as prescribed — do not stop early.
• Drink plenty of fluids and rest if you have any side effects from treatment.

Medical treatments

Antibiotics are the standard treatment. For most people, a single injection of a penicillin-based antibiotic is effective. If you are allergic to penicillin, your doctor can give alternative antibiotics. For late-stage syphilis or nerve involvement, you may need several doses over a few weeks. Your doctor will monitor you with blood tests after treatment to confirm the infection is cured.

When is surgery considered?

Surgery is not used to treat syphilis itself. In rare cases, if syphilis has caused damage to organs such as the heart or blood vessels, you may need surgery to treat those complications, but the infection itself is treated with antibiotics.

Living with this condition

After treatment, most people feel back to normal. You will need to attend follow-up appointments for blood tests at 3, 6, 12, and sometimes 24 months after treatment to make sure the infection is gone. During this time, it is important to use condoms and avoid sex with new partners until your doctor says it is safe.

Lifestyle tips

• Use condoms every time you have sex to prevent re-infection or passing it to others.
• Inform your sexual partners so they can get tested and treated.
• Attend all follow-up appointments as scheduled.
• If you have other health conditions, keep managing them as usual.

Diet and exercise

There is no special diet or exercise needed for syphilis, but a healthy lifestyle supports your immune system. Eat balanced meals, stay active, and drink plenty of water.

Mental health and emotional wellbeing

A syphilis diagnosis can be stressful or embarrassing, but it is important to remember that it is a common infection and nothing to be ashamed of. You are taking a responsible step by getting treatment. If you feel anxious, depressed, or have trouble coping, talk to your doctor or a counselor. Help is available.

Prevention

Yes, syphilis can be prevented. The most effective way is to use condoms correctly every time you have sex. Limiting your number of sexual partners and getting tested regularly if you are at risk also helps. If you are in a long-term relationship with a partner who is free of syphilis, you are not at risk.

Screening programmes

If you are sexually active and have multiple partners or are in a high-risk group, ask your doctor about routine syphilis screening. Pregnant women are routinely screened for syphilis to prevent passing it to the baby.

Complications

If left untreated

• If untreated, syphilis can damage the heart, blood vessels, and brain many years later.
• It can cause blindness, deafness, paralysis, and dementia.
• In pregnant women, untreated syphilis can cause stillbirth or serious health problems in the baby.

Long-term outlook

The outlook is excellent if syphilis is caught early and treated properly. Even in later stages, treatment can stop further damage and cure the infection. Most people recover fully and can live a normal, healthy life. Remember, syphilis is curable — and you are taking the right step by seeking care.
