Syphilis is treated with medication?

Hello, doctor.
I would like to ask about my recent syphilis diagnosis (confirmed in January).
I took minocycline for 14 days, twice a day, one capsule each time.
At that time, I had the following symptoms: syphilitic rash on my body and soles of my feet, swollen lymph nodes on both sides of the back of my neck, itchy scalp, and extremely dry eyes with slight stinging.
After taking the medication, the syphilitic rash on my body disappeared, but there are still some spots on my soles.
There are still one or two uncertain spots that I tend to pick at, and I have peeling skin.
The lymph nodes, which were originally quite large, have now reduced to two small ones still located at the back of my neck.
The itchy scalp and dry eyes gradually improved while I was on the medication, but after finishing the 14-day course, a week or two later, I started experiencing extremely dry eyes with slight stinging again.

On February 2nd, I went to the hospital for a blood test, and the results were RPR (1:32 positive) and TPPA (>1:1280 positive).
The doctor suggested I receive an injection of Benzathine penicillin, but I expressed my preference to try oral medication first.
I also informed the doctor that I had taken minocycline for 14 days less than a month ago, so the doctor prescribed tetracycline for 14 days, four times a day, 500 mg each time.

I have a few questions:
1.
Can I really rely on oral medication alone for treatment?
2.
I have read some literature stating that minocycline is more effective than tetracycline.
Will taking tetracycline now be less effective?
3.
I came across an article mentioning that after completing a 14-day course of medication, it is generally recommended to wait three months before having blood tests to assess changes and treatment effectiveness.
So, is it unnecessary for me to have another test in about a month? Since I have already started taking tetracycline, should I continue with it?
Thank you, doctor, for taking the time to answer my questions amidst your busy schedule.

Hello: After treatment for syphilis, the titers will gradually decrease, but it is still necessary to monitor for at least three months.
There is no such thing as being completely cured; some individuals may no longer have symptoms and their titers may improve, but they should still have follow-up testing once a year.
Medication is certainly effective, and literature supports this.
There is no issue of who is better or worse; if the titers do not decrease with oral medication, a different method (such as injections) should be considered.
If symptoms persist, medical attention is required.
Additionally, it is important to be cautious with sexual activity; the physician will monitor your treatment, and you should avoid engaging in unsafe sexual practices.
If you contract another sexually transmitted infection, it will be even more challenging.
Thank you for your inquiry.

Managing syphilis effectively requires a comprehensive understanding of the disease, its treatment options, and the importance of follow-up care. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum, and it can present in various stages, each requiring different management strategies.
In your case, you were initially treated with minocycline for 14 days, which is an antibiotic that can be effective against syphilis, particularly in its early stages. However, the standard treatment for syphilis, especially in cases of primary and secondary syphilis, is typically benzathine penicillin G, which is considered the first-line treatment. While minocycline and tetracycline can be alternatives for those allergic to penicillin, they may not be as effective as penicillin in eradicating the infection completely.

1. Is Oral Medication Enough for Effective Treatment?
Oral antibiotics like minocycline and tetracycline can be effective for treating syphilis, but they are generally not the preferred treatment. The effectiveness of these medications can vary, and they may not provide the same level of cure as benzathine penicillin. If your symptoms have improved but not completely resolved, it may indicate that the oral treatment was insufficient. It is crucial to follow your healthcare provider's recommendations and consider the standard treatment options available.

2. Comparative Effectiveness of Minocycline and Tetracycline:
You mentioned that you read literature suggesting that minocycline is more effective than tetracycline. This is generally true; minocycline has a broader spectrum of activity and better tissue penetration than tetracycline. However, the choice of antibiotic should be guided by your healthcare provider based on your specific circumstances, including any previous treatments and your overall health.

3. Timing of Follow-Up Blood Tests:
It is correct that follow-up blood tests for syphilis, such as the RPR (Rapid Plasma Reagin) test, are typically recommended to be done three months after treatment to assess the effectiveness of the therapy. Testing too soon after treatment may not provide an accurate reflection of whether the infection has been cleared, as it can take time for the antibodies to decrease. Since you are planning to have another blood test soon after starting tetracycline, it may not be necessary at this point. Instead, focus on completing the full course of tetracycline as prescribed and then follow up with your healthcare provider for further testing in a few months.

In summary, while oral medications can be part of the treatment for syphilis, they may not be the most effective option compared to benzathine penicillin. It is essential to communicate with your healthcare provider about your treatment plan, any lingering symptoms, and the timing of follow-up tests. If you have concerns about the effectiveness of your current treatment or if symptoms persist, it may be worth discussing the possibility of switching to the standard treatment with your doctor. Regular follow-up and adherence to the prescribed treatment regimen are crucial for managing syphilis effectively and preventing complications.
