Syphilis initially presents with the appearance of a painless [[chancre]] after 3-4 weeks of exposure. If left untreated, the [[chancre]] self resolves and the patient may progress to develop [[constitutional sypmtoms|constitutional symptoms]] and a generalized symmetric rash in four to eight weeks. In less than 10% of individuals, complications such as [[hepatitis]], [[iritis]], [[nephritis]], and neurological problems may develop at this stage. However, it resolves in four to eight weeks without treatment and patient enters into asymptomatic latent phase. About a quarter of patients may develop recurrence of similar symptoms in one year. If left untreated, 35% of patients may develop tertiary syphilis which include complications such as cardiovascular involvement, neurologic infection and [[Gummatous|gummatous lesions]] involving [[skin]], [[bone]] and [[joints]] which is associated with significant [[morbidity]] and [[mortality]]. The prognosis of syphilis varies by stage of disease. Prognosis of primary and secondary syphilis is good with treatment. For tertiary syphilis, prognosis varies by site of involvement and duration of disease. 90% of patients with [[neurosyphilis]] respond to treatment. However, mortality rates are high with cardiovascular complications.<ref name="pmid1951814">{{cite journal| author=Thomas SB, Quinn SC| title=The Tuskegee Syphilis Study, 1932 to 1972: implications for HIV education and AIDS risk education programs in the black community. | journal=Am J Public Health | year= 1991 | volume= 81 | issue= 11 | pages= 1498-505 | pmid=1951814 | doi= | pmc=1405662 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=1951814  }} </ref><ref name="pmid13301322">{{cite journal| author=GJESTLAND T| title=The Oslo study of untreated syphilis; an epidemiologic investigation of the natural course of the syphilitic infection based upon a re-study of the Boeck-Bruusgaard material. | journal=Acta Derm Venereol Suppl (Stockh) | year= 1955 | volume= 35 | issue= Suppl 34 | pages= 3-368; Annex I-LVI | pmid=13301322 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=13301322  }} </ref><ref name="pmid10194456">{{cite journal| author=Singh AE, Romanowski B| title=Syphilis: review with emphasis on clinical, epidemiologic, and some biologic features. | journal=Clin Microbiol Rev | year= 1999 | volume= 12 | issue= 2 | pages= 187-209 | pmid=10194456 | doi= | pmc=88914 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=10194456  }} </ref><ref name="pmid17235095">{{cite journal| author=French P| title=Syphilis. | journal=BMJ | year= 2007 | volume= 334 | issue= 7585 | pages= 143-7 | pmid=17235095 | doi=10.1136/bmj.39085.518148.BE | pmc=1779891 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=17235095  }} </ref>

Initial presentation of syphilis is appearance of painless chancre after 3-4 weeks of exposure. If left untreated, chancre self resolves and may progress to develop [[constitutional sypmtoms]] and generalised symmetric rash in four to eight weeks. In less than 10% of individuals, complications such as [[hepatitis]], [[iritis]], [[nephritis]], and neurological problems may develop at this stage. However, it resolves in four to eight weeks without treatment and patient enters into asymptomatic latent phase. About a quarter of patients may develop recurrence of similar symptoms in one year. If left untreated, 35% of patients may develop tertiary syphilis which include complications such as cardiovascular involvement(80-85%, [[aortic aneurysm]], [[aortic regurgitation]], [[angina]], [[heart failure]]), neurologic infection (5-10%, cranial nerve dysfunction, [[meningitis]], [[stroke]], acute or chronic altered mental status, loss of vibration sense, and auditory or ophthalmic abnormalities) and gummatous lesions involving skin, bone and joints which is associated with significant [[morbidity]] and [[mortality]].<ref name="pmid17235095">{{cite journal| author=French P| title=Syphilis. | journal=BMJ | year= 2007 | volume= 334 | issue= 7585 | pages= 143-7 | pmid=17235095 | doi=10.1136/bmj.39085.518148.BE | pmc=1779891 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=17235095  }} </ref><ref name="pmid1951814">{{cite journal| author=Thomas SB, Quinn SC| title=The Tuskegee Syphilis Study, 1932 to 1972: implications for HIV education and AIDS risk education programs in the black community. | journal=Am J Public Health | year= 1991 | volume= 81 | issue= 11 | pages= 1498-505 | pmid=1951814 | doi= | pmc=1405662 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=1951814  }} </ref><ref name="pmid13301322">{{cite journal| author=GJESTLAND T| title=The Oslo study of untreated syphilis; an epidemiologic investigation of the natural course of the syphilitic infection based upon a re-study of the Boeck-Bruusgaard material. | journal=Acta Derm Venereol Suppl (Stockh) | year= 1955 | volume= 35 | issue= Suppl 34 | pages= 3-368; Annex I-LVI | pmid=13301322 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=13301322  }} </ref><ref name="pmid10194456">{{cite journal| author=Singh AE, Romanowski B| title=Syphilis: review with emphasis on clinical, epidemiologic, and some biologic features. | journal=Clin Microbiol Rev | year= 1999 | volume= 12 | issue= 2 | pages= 187-209 | pmid=10194456 | doi= | pmc=88914 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=10194456  }} </ref>

Overview

Syphilis initially presents with the appearance of a painless chancre after 3-4 weeks of exposure. If left untreated, the chancre self resolves and the patient may progress to develop constitutional symptoms and a generalized symmetric rash in four to eight weeks. In less than 10% of individuals, complications such as hepatitis, iritis, nephritis, and neurological problems may develop at this stage. However, it resolves in four to eight weeks without treatment and patient enters into asymptomatic latent phase. About a quarter of patients may develop recurrence of similar symptoms in one year. If left untreated, 35% of patients may develop tertiary syphilis which include complications such as cardiovascular involvement, neurologic infection and gummatous lesions involving skin, bone and joints which is associated with significant morbidity and mortality. The prognosis of syphilis varies by stage of disease. Prognosis of primary and secondary syphilis is good with treatment. For tertiary syphilis, prognosis varies by site of involvement and duration of disease. 90% of patients with neurosyphilis respond to treatment. However, mortality rates are high with cardiovascular complications.[1][2][3][4]

Natural history

  • Painless chancre appears 3-4 weeks after exposure.
  • Chancre typically resolves, after which the patient may develop constitutional symptoms and generalized symmetric rash in 4 to 8 weeks.
    • In less than 10% of individuals, complications such as hepatitis, iritis, nephritis, and neurological problems may develop at this stage.
  • This stage is typically self limited to 4 to 8 weeks without treatment and patient enters into asymptomatic latent phase.
  • Approximately 25% of patients develop recurrent symptoms in one year.
  • Approximately 35% of patients develop tertiary syphilis, which includes the following complications:

Complications

Complications that can develop as a result of syphilis include:

Ocular

Auditory

Neurological

Cardiovascular

Renal

Musculoskeletal

Dermatological

Gastrintestinal

Gummatous lesions

Prognosis

The prognosis of syphilis depends on the stage of disease:[1][2][3]

Primary and secondary syphilis

Prognosis is good with appropriate antimicrobial treatment and most patients will have full resolution of symptoms.

Tertiary syphilis

Prognosis varies by site of involvement and duration of disease:

  • 90% of patients with neurosyphilis respond to treatment.
  • Gummatous lesions reverse with treatment.
  • Mortality rates are high with cardiovascular complications.
  • 20% of patients with tertiary syphilis die of complications.
