Syphilis infection issues?
Hello Doctor, I was recently diagnosed with syphilis.
My RPR result was 1:8 and TPHA was 25.11.
I received a single dose of penicillin for treatment, but I had a negative rapid test result last October.
I have a few questions regarding my situation:
1.
Is it possible for a recent infection to have an RPR result of only 1:8? I found information online suggesting that acute infections usually present with much higher titers, which makes me confused about this result.
2.
Could it be that I was infected much earlier without realizing it, and then my RPR level decreased to 1:8? Or could a very recent infection cause such a low titer? I ask this because I informed my doctor about the negative rapid test result from over six months ago, and the doctor decided to administer only one dose of penicillin for treatment.
If the rapid test was inaccurate and this titer reflects an infection older than a year, would the treatment approach have been different?
3.
If the treatment is successful, is it possible for the RPR to drop to undetectable levels? If it becomes undetectable, can a standard rapid test still show a negative result?
4.
I experienced sudden hearing loss in one ear around March.
Could this be related to syphilis?
5.
If treated early, will there still be any side effects on the body?

Hello:
1.
Is it possible for an RPR result to be as low as 1:8 after a recent infection? The information I found online suggests that acute infections usually yield much higher results, so I'm confused about this outcome.
—> Any number is possible.
2.
Could it be that I was infected much earlier without realizing it, and then the RPR decreased to 1:8? —> If untreated, the chance of a decrease is very low, or could a very recent infection lead to such a low index? —> I want to inquire about this: I informed the physician that I had a negative rapid test result over six months ago, so the doctor decided to administer only one dose of penicillin for treatment.
However, if the rapid test was inaccurate at that time and this index reflects an infection over a year old, would the treatment approach have been different? —> The standard is one dose of three.
If the treatment is successful, is it possible for the RPR to decrease to undetectable levels? If it is undetectable, could a standard rapid test still show negative? —> It is possible for the RPR to return to normal; I am not sure how accurate the rapid test you used is, but blood tests are the gold standard.
4.
I experienced sudden hearing loss in one ear around March; could this also be related to syphilis? —> Syphilis symptoms can vary widely, but I have not seen many cases.
5.
If treated early, will there still be side effects? —> It is important to have long-term follow-up for at least a few years, as some individuals may experience a resurgence and require further treatment.
Early treatment of an infection certainly has less impact, but it cannot be said that there are no effects at all.
Wishing you good health.

Understanding syphilis infection is crucial, especially when faced with a recent diagnosis and treatment. Let's address your questions and concerns systematically.
1. RPR Results and Acute Infection: The Rapid Plasma Reagin (RPR) test is a non-treponemal test used to screen for syphilis. A result of 1:8 indicates a reactive test, but it is relatively low for someone with an acute infection. Typically, acute syphilis infections can present with higher titers, often in the range of 1:32 or higher. However, it is important to note that RPR titers can vary significantly among individuals and may not always correlate directly with the duration or severity of the infection. It is possible to have a lower titer even in the context of recent infection, especially if the immune response is not robust.
2. Historical Infection vs. Recent Infection: It is indeed possible that you may have been infected longer ago than you realize. RPR titers can decrease over time, especially if the infection was treated or if the body has naturally cleared the infection. If your RPR was negative six months ago, and now it is 1:8, it raises the possibility of a recent infection, but it could also indicate a chronic infection that has been present for a longer period. The decision to treat with a single dose of penicillin is often based on the clinical judgment of the physician, considering the history and test results. If there was a concern that the infection was older, a more aggressive treatment approach might have been warranted.
3. Post-Treatment RPR Results: After successful treatment for syphilis, it is common for RPR titers to decrease. In some cases, they may become undetectable, which is a sign of successful treatment. However, it is also possible for titers to remain low but still reactive. If the RPR becomes undetectable, it is likely that a follow-up rapid test would also yield a negative result. It’s important to have follow-up testing to monitor the response to treatment.
4. Sudden Hearing Loss: Sudden sensorineural hearing loss can be associated with syphilis, particularly in its tertiary stage, where it can affect various organs, including the auditory system. If you experienced sudden hearing loss, it would be prudent to discuss this with your healthcare provider, as it may warrant further investigation to determine if there is a connection to your syphilis infection or if other factors are at play.
5. Side Effects of Early Treatment: Early treatment of syphilis with penicillin is generally safe and effective. Most patients do not experience significant side effects from the treatment. However, some may experience a Jarisch-Herxheimer reaction, which is a temporary reaction to the release of toxins from the dying bacteria. This can include fever, chills, and malaise, but it is typically self-limiting and resolves within 24 hours.
In conclusion, your situation underscores the importance of ongoing communication with your healthcare provider. Regular follow-up testing and discussions about your symptoms and treatment response are essential for managing syphilis effectively. If you have further concerns or symptoms, do not hesitate to reach out to your healthcare provider for personalized advice and care.
