TYPES OF

GENITAL ULCERS

Early : Primary syphilisEarly : Primary syphilis

• IP: 1-3 weeks• Usually Painless single papule then became

ulcer, round/oval• Well circumscribed, clean floor, no exudate• Usually no vesicle• Regional lymphadenopathy• Any anogenital ulcer should be considered to

be due to syphilis unless proven otherwise.• 90% genital ulcer, 10% extragenital

Primary syphilis (9 – 90 days)

Chancre

Early: Secondary syphilisEarly: Secondary syphilis

• 6 weeks to 6 months • Stage of bacteremia• May cause uveitis, cranial nerve

palsies, hepatitis and splenomegaly

• The most common features – fever,– lymphadenopathy,– diffuse non irritating rash– condyloma lata

Patchy alopecia of secondary syphilis. Hair loss also occurs commonly from the lateral third of the eyebrows.

Early: Secondary syphilisEarly: Secondary syphilis

Malignant syphilis – widespread necrotic papulopustules and ulcers with severe systemic symptoms

Maculo-papular syphilide

Diagnosis of Secondary Diagnosis of Secondary SyphilisSyphilis

• All serological tests for syphilis are expected to be positive in secondary syphilis

• RPR/ VDRL titres in untreated cases are often > 1:8 (VDRL) and > 1: 16 (RPR)

• If a specific treponemal test is used for diagnosis and is found to be positive, use the VDRL/ RPR test to determine disease activity, and to monitor response to therapy

Early Latent SyphilisEarly Latent Syphilis

• Diagnosed by a POSITIVE SEROLOGY without symptoms and signs in a person known to be sero-negative in the previous 2 years

LATE SYPHILIS: > 2 yearsLATE SYPHILIS: > 2 years• Late latent: Asx• Benign Tertiary Syphilis (Gumma)

– 1 – 45 (average 15) years after infection, – destructive granulomatous lesions on skin,

bones• Cardiovascular Syphilis

HIV patient

Tertiary syphilis (3 – 12 years later)

Necrotic nodules or plaques

Gummas on lower limb

TreatmentTreatment

1. Early Syphilis

- IM Benzathine Penicillin 2.4 mega units single dose or

- IM Procaine Penicillin G 600,000 daily x 10/7

Early Syphilis: For patients Early Syphilis: For patients allergic to penicillin:allergic to penicillin:

1. T. Doxycycline 100 mg bd x 14/7: (contraindicated in pregnancy)

2. T. Erythromycin 500 mg qid x 14/73. T. Erythromycin ES 800 mg qid x 14/74. IM Ceftriaxone 250 mg daily x 10/75. T. Azithromycin 2 G single dose

• Erythromycin should not be used because of the high risk of failure to cure the foetus.

• If erythromycin is used, paediatricians must be alerted and babies have to be treated prophylactically with penicillin and monitored.

Penicillin allergy in Pregnant WomenPenicillin allergy in Pregnant Women

• Should be meticulously interviewed regarding the validity of the history.

• Currently, no proven alternative therapies to penicillin are available for treating neurosyphilis, congenital syphilis or syphilis in pregnancy.

• Therefore, skin testing, with desensitisation, if indicated, should be done for these patients.

MANAGEMENT OF PATIENTS WITH MANAGEMENT OF PATIENTS WITH HISTORY OF PENICILLIN ALLERGYHISTORY OF PENICILLIN ALLERGY

• Desensitisation should be done in a hospital setting because serious IgE-mediated allergic reactions may occur.

• A protocol is recommended (refer STI guideline). – Oral penicillin in increasing concentration is

administered every 15 minutes. Sensitisation is completed within 4 hours with a cumulative dose of 1.3 million units of penicillin V.

– An acute febrile illness with headache, myalgia, chills and rigors and resolving within 24 hours.

– This is common in early syphilis but is usually not important unless • neurological or ophthalmic involvement or • in pregnancy when it may cause fetal

distress and premature labour (second half of pregnancy)

Jarisch-Herxheimer reactionJarisch-Herxheimer reaction

Jarisch-Herxheimer reactionJarisch-Herxheimer reaction• It is uncommon in late syphilis but can potentially be life

threatening if there is involvement of strategic sites (coronary ostia, larynx, nervous system).

• Prednisolone can reduce the reaction.

Recommendation• In early syphilis : Treat with Paracetamol • In Neurosyphilis, Cardiovascular, certain cases of benign

tertiary and late latent syphilis:– Treat with Prednisolone 40-60mg daily for 3 days: begin 24 hours

before treatment and for 2 days after starting treatment.

ADVICE• Abstain from sex until 1 week after they and their partner(s) have

completed treatment.

CONTACT TRACING • Examine and investigate all sex partners and treat

epidemiologically.

• Primary syphilis, notify sexual partners within the past 3/12.

• Secondary syphilis with clinical relapse or in early latent syphilis: 2 years

• All patients should be offered patient and provider referral as a method of contacting any sexual partner. The method agreed upon with the patient should be clearly documented.

• Epidemiological treatment for asymptomatic contacts of early syphilis is recommended.

Incubating/ Epidemiological Rx: Incubating/ Epidemiological Rx: PartnerPartner

• IM B. Penicillin 2.4 mega units single dose or

• T. Doxycycline 100 mg bd x 14/7 or

• T. Azithromycin 1 G single dose

Congenital SyphilisCongenital Syphilis

• 50-80% of exposed neonates.

Caused by transplacental transmission of spirochetes; the transmission rate approaches 90% if the mother has untreated primary or secondary syphilis.

The child is at greatest risk of

contracting syphilis when the mother is in the early stages of infection

A woman in the secondary stage of syphilis decreases her child's risk of developing congenital syphilis by 98% if she receives treatment before the last month of pregnancy


Untreated Syphilis in Untreated Syphilis in PregnancyPregnancy

Fetal infection can develop at any time during gestation.

Because inflammatory changes do not occur in the fetus until after the first trimester of pregnancy, organogenesis is unaffected.

All organ systems may be involved.

Can cause: Miscarriages, Premature birth Stillbirths Death of newborn babies: pulmonary haemorrhage.

Manifestations are defined as Early if they appear in the first 2 years of life Late: develop after age 2 years.

Early-onset disease, result from transplacental spirochetemia and are

analogous to the secondary stage of acquired syphilis. (Congenital syphilis does not have a primary stage)

Late-onset disease (>2 years) is considered contagious.


Early-onset congenital syphilis Early-onset congenital syphilis (before or at age 2 y)(before or at age 2 y)

60% are asymptomatic at birth. Sx develop within the first 2/12 of life.

Almost 100% has hepatomegaly; biochemical evidence of liver dysfunction is usually observed.

Common Sn: skeletal abnormalities, rash, and generalized lymphadenopathy.

Radiographic abnormalities, periostitis or osteitis, involve multiple bones. Sometimes, the lesion is painful and an infant will favor an extremity (pseudopalsy)

Maculopapular rash, may involve palms and soles.

In contrast to acquired

syphilis, a vesicular rash and bullae (pemphigus syphiliticus) may develop - highly contagious.

Mucosal involvement may present as rhinitis ("snuffles") – poor feeding.

Nasal secretions are highly contagious.


• Hematological abnormalities include anemia and thrombocytopenia. Some have leukocytosis.

• Abnormal CSF examination – Seen in a half of symptomatic infants,– 10% of asymptomatic baby.


Late Onset ManifestationsLate Onset Manifestations

Neurosyphilis and involvement of the teeth, bones, eyes, and the eighth cranial nerve, as follows: Bone involvement - Saber shins, saddle nose, short

maxillae, protruding mandible, swollen knees Higoumenakis sign, enlargement of the sternal end

of clavicle in late congenital syphilis. Teeth involvement - Notched, peg-shaped incisors

(Hutchinson teeth) Pigmentary involvement - Linear scars (rhagades) at

the corners of the mouth and nose result from bacterial infection of skin lesions.

Interstitial keratitis - Presents in the 1st or 2nd decade of life

Sensory-neural hearing loss (eighth cranial nerve deafness) - Presents between age 10 and 40 years.

Classic Hutchinson triadClassic Hutchinson triad

Defective incisors, interstitial keratitis, eighth cranial nerve deafness

Infants should be evaluated if they Infants should be evaluated if they were born to sero +ve women who:were born to sero +ve women who:

• Have untreated syphilis• Were treated for syphilis less than 1

month before delivery• Were treated for syphilis during

pregnancy with a non - penicillin regimen• Did not have the expected decrease in

RPR titre after treatment• Were treated but had insufficient serologic

follow-up during pregnancy to assess disease activity

EVALUATION OF INFANTEVALUATION OF INFANT

• A thorough physical examination• RPR (compare with mother’s titre) /

EIA • FTA-Abs• CSF analysis for cells, protein and

CSF-VDRL test• Long bones X-ray • Chest X-ray

Treat if they have:Treat if they have:Any evidence of active diseaseA reactive CSF-VDRL / FTA-AbsAn abnormal CSF finding ( WBC > 5/ mm3 or

protein > 50 mg / dl ) regardless of CSF serology

Serum RPR titre that are at least 4 times higher than their mother's.

Positive EIA-IgM antibody

* Treatment (with penicillin) before the development of late symptoms is essential

RxRx• Aqueous Cystalline Penicillin G: 50,000 units/kg/dose 12

hourly for first 7 days then 8 hourly for the following 3-7 days OR

• Procaine Penicillin, 50,000 units/kg daily IM for 10 - 14 days OR

• *IV/IM Ceftriaxone 75 mg/kg (< 30 days old) or 100 mg/kg (>30 days old)

• *If more than a day of treatment is missed, the whole course should be restarted

• Infants who should be evaluated but whose follow-up cannot be assured should be treated with a single dose of Benzathine Penicillin, 50,000 units/kg IM.

•

F/up and MonitoringF/up and Monitoring

Sero-positive untreated infants must be closely monitored at 1, 2, 3, 6, and 12 months of age. RPR should decrease by 3/12 of age and

usually disappear by 6/12 of age. Treat (with the same regimen as above) if:

Symptoms and signs persist or recur RPR titre increase fourfold or more by 3/12 of

age RPR still positive by 6/12 of age TPHA still positive by 1 year of age

Treated InfantsTreated Infants• Monitored clinically and serologically

at 1, 3, 6, 12, 18, and 24 months. Lumbar puncture should be repeated 6 monthly till normal.

THERAPY OF OLDER INFANTS AND THERAPY OF OLDER INFANTS AND CHILDRENCHILDREN

• After the newborn period, children discovered to have syphilis should have a CSF analysis to rule out congenital syphilis.

• Any child with congenital syphilis or with neurologic involvement should be treated with – Aqueous Cystalline Penicillin, 200,000-

300,000 units/kg/day administered as 50,000 units/kg/dose 4-6 hourly for 10 to 14 days (B, III)
