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]
Schematic representation of antibody. Anti-cardiolipin antibodies (ACA) are antibodies often directed against cardiolipin and found in several diseases, including syphilis, [1] antiphospholipid syndrome, livedoid vasculitis, vertebrobasilar insufficiency, Behçet's syndrome, [2] idiopathic spontaneous abortion, [3] and systemic lupus erythematosus (SLE).

A new proven protocol in which doxycycline is used to prevent sexually transmitted infections — called doxyPEP — has been an apparent sleeper hit among gay and bisexual men.
The latent stage that results can last a lifetime in many cases. In a few cases, the disease exits latency and enters a tertiary phase, in which destructive lesions of skin, bone, and cartilage ensue. Unlike yaws and bejels, syphilis in its tertiary stage often affects the heart, eyes, and nervous system, as well. [13]
The VDRL is a nontreponemal serological screening for syphilis that is also used to assess response to therapy, to detect central nervous system involvement, and as an aid in the diagnosis of congenital syphilis. The basis of the test is that an antibody produced by a patient with syphilis reacts with an extract of ox heart (diphosphatidyl ...
Michigan saw a 200% increase in the rate of congenital syphilis from 2017-2021, as a rising number of babies in the U.S. are born with the infection.
