SynopsisSyphilis is a chronic systemic disease with multiple clinical presentations caused by the spirochete Treponema pallidum. Disease is characterized by 3 stages of active disease (primary, secondary, and tertiary), interrupted by latent periods. Disease is acquired via intimate contact with infected lesions (usually sexual contact), by blood transfusion, or transplacentally to the fetus. After the advent of antibiotics, the long-term sequelae of infection with the treponeme (neurosyphilis, cardiovascular syphilis, and gummas) have become uncommon. In untreated syphilis, 15% of patients develop benign late syphilis with skin (70%), bone (10%), and/or mucous membranes (10%). About 16% of untreated patients will develop either neurosyphilis or cardiovascular syphilis.
Disease occurs worldwide. More than 80% of reported disease in the US is in the Southern region.
In the US, syphilis cases occur more often in males (5:1 male/female ratio), and in blacks, Hispanics, men who have sex with men, and prostitutes. An increased incidence of syphilis is associated with HIV positivity.
Gummas are locally destructive lesions of skin, bone, or involved organs, which may heal spontaneously with scarring but often recur. The term "gumma" is derived from the appearance of slimy central necrotic tissue in ulcers.
Skin lesions are usually asymptomatic. When the tongue is involved with an early glossitis, there may be discomfort eating hot or acidic foods. Bone lesions are painful. Symptoms of neurosyphilis may include headache, dizziness, paresis, behavior change, dementia, pain, ataxia, blindness, deafness, incontinence, and impotence.
Systemic signs of tertiary disease include a heart murmur, cranial nerve palsies, pupillary abnormalities (Argyll Robertson pupil), signs of tabes dorsalis, foot ulcers, and iritis.
Tertiary, or late syphilis, occurs after a latent period of 2–20 years after infection. Damage to the skin, bones, and to the CNS and cardiovascular systems is due to host delayed-type hypersensitivity reactions to a small number of organisms. An accelerated course and neurologic disease are observed more often in HIV infection, when disease progresses to the tertiary phase in months rather than years. Skin lesions endure for months to years untreated. If present, neurosyphilis or cardiovascular syphilis may result in death. Prognosis depends upon the duration and extent of disease.
