Syphilis


Can syphilis antibodies be detected during the hard chancre stage?
During the hard chancre phase of syphilis, a portion of cases can test positive for Treponema pallidum, although some tests may return negative results. In such cases, it is advisable to retest after one month. The earliest detectable antibodies for Treponema pallidum are usually of two types: a Treponema pallidum-specific antibody, which appears earlier than the non-specific antibodies. There are tests for non-specific antibodies, commonly referred to as RPR or TRUST, which are standard practices in major hospitals. Therefore, in early-stage syphilis or primary syphilis with hard chancre, it is possible to find Treponema pallidum-specific antibodies positive, RPR or TRUST negative, or both negative. If syphilis is strongly suspected in such cases, a retest is recommended after one month.


Is cervical lymphadenopathy related to syphilis?
Enlargement of cervical lymph nodes is somewhat related to syphilis. Although cervical lymph node enlargement is not necessarily solely caused by syphilis, if syphilis progresses to its secondary or tertiary stages, it tends to cause lymph node enlargement, and severe cases may even lead to ulceration. This happens because after a syphilis infection, immune responses in the lymph cells are triggered by the Treponema pallidum, leading to the enlargement of cervical lymph nodes, and also possibly the lymph nodes under the arms and in the groin area. In such cases, it is advised to seek timely medical attention, complete the necessary immunological testing, and ensure an accurate diagnosis of syphilis. If cervical lymph node enlargement occurs, prolonged treatment with penicillin should be administered, as it effectively controls the Treponema pallidum and can help reduce the severity of the lymph node enlargement.


Is third-stage syphilis contagious?
Third-stage syphilis is infectious, but its contagiousness is relatively weak compared to first-stage and second-stage syphilis. The titers detected in third-stage syphilis are usually lower, so its infectiousness is comparatively minor. However, third-stage syphilis still has the capability to infect others. Therefore, patients with third-stage syphilis must actively seek treatment and refrain from having sexual relations with others, while also enhancing their own immunity.


What are the early symptoms of syphilis?
Syphilis is divided into overt and latent syphilis. Latent syphilis, regardless of whether it is early or late stage, shows no symptoms at all and can only be confirmed by blood testing. The symptoms in the early stage are mainly those of overt syphilis, primarily manifestations of primary syphilis. The stages of primary, secondary, and tertiary syphilis begin with the appearance of a lesion at the site of infection, typically about 0.5 to 1 centimeter in diameter, with a hard, dark red nodule that feels like cartilage. The surface may have ulcers; it may be painless, or there may be no pain at all. Subsequently, nearby lymph nodes may become enlarged. This swelling of the lymph nodes is characterized by being painless, usually unilateral, with no redness or rupture. These are the clear symptoms of overt primary syphilis. If treated properly at this stage, recovery is generally rapid.


How long is the latency period of syphilis?
Syphilis is a chronic infectious disease caused by the bacterium Treponema pallidum (TP), primarily transmitted through sexual contact and blood. The impact of syphilis is significant as it can affect all bodily tissues and organs, or can be transmitted through the placenta, leading to stillbirth, miscarriage, premature birth, and congenital infections. When syphilis is suspected, due to its complex clinical manifestations, a detailed medical history should be taken, a thorough physical examination conducted, and repeated laboratory tests performed to ensure an early and accurate diagnosis. It is important to trace back to any unprotected sexual contacts within the last six weeks and to routinely screen the sexual partners of patients for syphilis as well. Syphilis is divided into three stages: The diagnosis of primary syphilis is mainly based on the history of exposure, the incubation period (six weeks), typical clinical manifestations, and laboratory tests, noting that a negative syphilis serology result alone should not exclude the diagnosis of syphilis. The diagnosis of secondary syphilis primarily relies on the history of exposure, typical clinical manifestations, especially skin and mucosal lesions, combined with laboratory tests. The diagnosis of tertiary syphilis is mainly based on the history of exposure, typical clinical manifestations, and laboratory tests. Neurosyphilis can also be assessed through cerebrospinal fluid examination. Congenital syphilis primarily requires a maternal history of the disease, combined with typical clinical manifestations and laboratory tests for diagnosis.


Third-stage syphilis has no symptoms.
Once tertiary syphilis has developed, it is highly unlikely for there to be no symptoms. Tertiary syphilis is a late stage of the disease, generally involving the skin, mucous membranes, cardiovascular system, and even the motor and nervous systems. If there are no symptoms present, it is generally not possible to be in the tertiary stage of syphilis. Therefore, if tertiary syphilis occurs, it will not be without symptoms.


How to determine if you have syphilis
To determine if one has syphilis, initial assessments should integrate clinical symptoms, including the presence of a chancre and syphilis rash. Subsequently, it is advised to visit an accredited hospital to undergo serological testing for syphilis, which involves the detection of both specific and non-specific antibodies of syphilis. A comprehensive evaluation of these findings can assist in diagnosing whether one is infected with syphilis. Once syphilis is confirmed, it is crucial to commence systematic and standardized treatment promptly. Generally, if both the syphilis-specific antibody test and the non-heated treponemal pallidum particle agglutination test are positive, these indicate an active syphilis infection. Treatment should be sought at a reputable medical facility, promptly utilizing penicillin for standardized treatment. If there is an allergy to penicillin, tetracycline antibiotics can be considered as an alternative.


How long is the latency period for tertiary syphilis?
The latency period of tertiary syphilis is not clearly defined, but it is certain that once tertiary syphilis appears, the duration of illness in patients generally exceeds two to three years, meaning the latency period is at least two to three years long. Of course, some patients may reach five to ten years. This depends on each individual's resistance as well as the virulence and amount of the virus. Additionally, if one contracts tertiary syphilis, it is crucial to seek timely and proper treatment, as it may be life-threatening.


Can tertiary syphilis be treated?
Third-stage syphilis is treatable, but typically, it develops two to three years after the initial syphilis infection, making it more severe than both the first and second stages—this is what we refer to as late-stage syphilis. Therefore, treating third-stage syphilis is somewhat more challenging than treating the first and second stages. Additionally, third-stage syphilis particularly tends to cause damage to cardiovascular, neurological, joint, and other organ systems. If it leads to severe complications, it can easily result in deformities, disabilities, or even death. Therefore, it is crucial to be especially vigilant if diagnosed with third-stage syphilis and to seek timely treatment at a hospital.


How long does tertiary syphilis appear?
Tertiary syphilis often appears two to three years after contracting syphilis. Syphilis is staged based on the time of onset, and is typically divided into primary, secondary, and tertiary stages. Tertiary syphilis is the latest and most severe stage among these, often affecting the heart, nervous system, skin, and other areas. Due to the risk of severe complications, early and timely treatment is recommended to prevent the occurrence of tertiary syphilis.
