The rapid plasma reagin test (RPR test or RPR titer) is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis or related non-venereal treponematoses. It is one of several nontreponemal tests for syphilis (along with the Wassermann test and the VDRL test).
The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).
Generally, diseases outlined within the ICD-10 codes A50-A64 within Chapter I: Certain infectious and parasitic diseases should be included in this category. Wikimedia Commons has media related to Infections with a predominantly sexual mode of transmission .
Inflammatory involvement of tertiary syphilis begins at the adventitia of the aortic arch which progressively causes obliterative endarteritis of the vasa vasorum. [3] This leads to narrowing of the lumen of the vasa vasorum, causing ischemic injury of the medial aortic arch and then finally loss of elastic support and dilation of the vessel. [3]
There is no definite treatment, but, because syphilis may be an underlying cause, it should be treated. However, because this sign is associated with neurosyphilis, it should be treated with crystalline penicillin 24 mU intravenous per day for 10 to 14 days.
Tertiary syphilis may occur approximately 3 to 15 years after the initial infection and may be divided into three different forms: gummatous syphilis (15%), late neurosyphilis (6.5%), and cardiovascular syphilis (10%). [3] [25] Without treatment, a third of infected people develop tertiary disease. [25] People with tertiary syphilis are not ...
For primary syphilis, TPPA has a sensitivity of 85% to 100%, and a specificity of 98% to 100%. [2] In secondary and late-latent syphilis, TPPA has a sensitivity of 98% to 100%. [2] Antibodies against other treponemal organisms, such as the T. pallidum subspecies endemicum, pertenue, or carateum, can cause false positive results.
[34] [10] The prevalence depends on the sensitivity of the immunologic methods applied. [1] The age of onset is often <5 years in the pediatric population, [18] with male predominance ranging from 2.5:1 to 5:1 in male-to-female ratio. [18] [10] The majority of PCH were accounted by congenital or tertiary syphilis in the early 1900s.
