The great imitator
  • Philippe Kestelyn, MD, PhD, MPH
  • Department of Ophthalmology
  • Ghent University Hospital
  • Belgium

Medical Society in 1879

Pubmed search
  • The great imitator strikes back
  • The return of the great imitator
  • The new great imitator (Lyme disease)

9
Great imitators
  • Internal medicine syphilis/ Lyme disease
  • Dermatology sarcoidosis/syphilis
  • Family medicine depression
  • Urgency medicine CO intoxication
  • Ophthalmology syphilis/ Lyme disease

10
SyphilisEpidemiology
  • 12 million new cases of syphilis worldwide each
    year
  • uncommon in Europe
  • serious problem in developing countries
  • serious sequelae / risk of congenital infection

11
Syphilis
  • sexually transmitted disease caused by Treponema
    pallidum
  • penetrates intact mucous membranes and abraded
    skin
  • incubation from 10 to 90 days
  • spread through the lymphatics to the bloodstream
  • hematogenous dissemination
  • 3 stages primary, secondary and tertiary
    syphilis
  • 70 of patients remain in latent stage after
    secondary stage
  • 30 go on to develop tertiary syphilis

12
Congenital Syphilis
  • transplacental transmission of T. pallidium first
    3 months
  • preventable!
  • intrauterine death or serious congenital
    abnormalities
  • generalized rash, jaundice, rhinitis
  • osteochondritis and X-ray abnormalities of bones
    in gt 90
  • chorioretinitis often present
  • DD rubella, CMV, toxoplasmosis
  • diagnosis FTA-ABS (IgM)

13
Late congenital syphilis
  • silent infection at birth
  • after 2 years
  • interstitial keratitis in 20
  • Hutchinsons triad
  • interstitial keratitis
  • notched thin upper incisors with abnormal spacing
  • deafness

14
Ocular involvement in the different stages of
syphilis
  • Primary syphilis conjunctival chancre (rare)
  • Secondary syphilis anterior and posterior
    involvement with pronounced inflammation
  • iritis (roseolae)
  • acute syphilitic posterior placoid
    chrioretinitis
  • inner retinal punctate lesions
  • retinal necrosis
  • Tertiary stage chronic anterior and posterior
    uveitis (chronic and mild vitritis, vasculitis,
    pigment epitheliopathy)

15
Anterior segment involvement in syphilis
  • starts as unilateral iritis
  • contralateral eye involved in 50 of patients
  • from mild nongranulomatous to severe
    granulomatous
  • often notion of skin rash (secondary stage)
  • resistant to corticosteroid treatment

16
Luetic anterior uveitis
  • 65-year-old male
  • bilateral anterior uveitis
  • resistant to topical steroid treatment
  • history of allergic skin reaction

17
Luetic anterior uveitis
18
Posterior segment complications of syphilis
  • posterior scleritis
  • vitritis
  • vasculitis
  • venous and arterial occlusive disease
  • chorioretinitis ,
  • retinal necrosis
  • acute syphilitic posterior placoid
    chorioretinitis
  • punctate inner retinopathy
  • retinal detachment with choroidal effusion
  • pseudoretinitis pigmentosa
  • macular edema, neuroretinitis
  • papillitis, optic perineuritis

Luetic perioptic neuritis
Bilateral papilledema in a young woman with
normal visual acuity Normal intracranial pressure
(imaging, lumbar puncture) LP confirms syphilitic
etiology
21
Luetic papillitis
  • 52 year-old white male
  • VA loss RE
  • fascicular VFD
  • nocturnal sweats
  • skin rash 2 months ago
  • VDRL , RPR
  • LP ?protein, VDRL pleocytosis,

22
Luetic vitreitis
A young African patient complains of unilateral
hazy vision Serologic tests for syphilis are
positive Lumbar puncture confirms asymptomatic
neurosyphilis penicillin G IV

Before treatment
23
Luetic retinitis (HIV-)
A 32-year- old white male patient complains of
hazy vision in the left eye no general health
problems, but syphilis serology strongly positive
24
Before and after treatment
Full recovery of visual acuity after penicillin G
therapy
25
Syphilis in patients with HIV infection
  • recognition of concurrent infection mandatory
  • accelerated course of syphilis
  • greater likelyhood of posterior uveitis,
    bilateral disease and neurosyphilis
  • treatment failures more common
  • serologic tests less reliable
  • neurosyphilis treatment for all patients ?

26
HIV and ocular syphilis
  • Bilateral disease
  • Accelerated course and extensive tissue
    destruction (retinalk necrosis)
  • False negative serology (indirect test)

Bilateral luetic uveitisLaboratory results
  • HIV positive 624 CD4 cells /microliter
  • Toxoplasmosis IgG - IgM -
  • Epstein-Barr IgG 260 IU/ml IgM -
  • CMV IgG gt 2000 IgM 2.0 (PCR negative)
  • HSV IgG 1700 IgM -
  • VZV IgG 1600 IgM
  • RPR negative

32
Prozone phenomenon
  • disequilibrium between antibody and antigen
    levels
  • ? present in less than 1 of patients with
    secondary syphilis
  • ? false negative test

33
Another presentation of syphilitic posterior
uveitis

bilateral inflammation
34
Leopard-spot like lesions on FA in the
cicatricial phase
35
  • Acute syphilitic placoid pigment epitheliopathy
  • first described by Gass
  • considered to be pathognomonic for syphilis
  • leopard spots on FA in the cicatricial phase

36

syphilitic involvement...

38
Non-specific tests for syphilis
  • cardiolipin from beef heart detects anti-lipid
    IgG and IgM formed in patients in response to
  • lipoidal material released from cells damaged by
    the infection
  • lipids in the surface of T. pallidum
  • VDRL (venereal disease research lab)
  • RPR (rapid plasma reagin test)
  • decline after effective AB therapy (indicator)
  • false positive results

39
Specific tests
  • detection of antibodies to specific treponemal
    antigens
  • FTA-ABS (fluorescent treponemal antibody
    absorption)
  • TPHA (T. pallidum hemagglutination assay)
  • become positive earlier and stay positive
    throughout life
  • cannot be used as indicators of therapeutic
    response

40
Treatment of ocular syphilis
  • same treatment regimen as for neurosyphilis
  • 18 to 24 million units of penicilllin G IV/day
    for 2 weeks
  • doxycycline 100 mg orally BID for 30 days
  • tetracycline 500 mg QID orally for 30 days
  • corticosteroids may be added once effective
    antibiotherapy has been started

41
Endemic treponematoses
  • Genus treponema 4 human pathogens
  • T. pallidum, subspecies pallidum venereal
    sypilis
  • T. pallidum, subspecies endemicum endemic
    syphilis or bejel
  • T. pallidum, subspecies pertenue yaws
  • Treponema carateum pinta

42
Endemic treponematoses Common features
  • Primary and secondary lesions
  • After latency some patients develop laate-stage
    disease
  • Cutaneous manifestations prominent
  • Penicillin drug of choice
  • No serologic tests at present can differentiate
    endemic trepanomatoses from each other or from
    venereal syphilis

43
Endemic treponematoses Important differences
  • Target population
  • Young children versus neonates and adults
  • Mode of transmission
  • Hand-to-hand or fomites versus sexual or
    transplacental
  • Tertiary and systemic involvement
  • Rare versus common
  • Optic atrophy and uveitis described in endemic
    syphilis (Tabara)

44
Take home
  • The great imitator is still there
  • Syphilis serolgy is mandatory in all patients
    presenting with unexplained intraocular
    inflammation
  • It is an inexpensive and reliable tool to unmask
    the great imitator
  • If not recognized in time, syphilitic retinitis
    may destroy the retina in a short time period
    (HIV patients)
  • Excellent prognosis with early and adequate
    treatment
