Congenital Syphilis • The incidence of congenital syphilis corresponds to the incidence of disease in women. Incidence increased dramatically during late 1980 and early 1990 but subsequently decreases. In almost three –quarter of cases the mother was not treated, or was inadequately treated.
Congenital Syphilis Congenital Syphilis — United States After 14 years of decline in the United States, the rate of congenital syphilis increased 15.4% between 2006 and 2007 (from 9.1 to 10.5 cases per 100,000 live births). In 2007, 430 cases were reported, an increase from 373 in 2006. This increase in the rate of congenital syphilis may relate to the increase in the rate of P&S syphilis among women that has occurred in recent years . Congenital Syphilis by State In 2007, 29 states had rates of congenital syphilis that exceeded the 2010 target of one case per 100,000 live births . NYS reported 6.4 /100000 in 2007
CDC Congenital Syphilis Reported cases and rates in infants < 1 year 2003-2007
Congenital Syphilis Clinical Presentation • Congenital syphilis lack a primary stage: because it is disseminated through blood • Fetal infections can occur at any time during pregnancy • Hepatomegaly is present in almost 100% • Necrotizing funisitis within the matrix of the umbilical cord is consider highly indicative • 60% of patients are asymptomatic
Maternal Syphilis Dx and treatment Test During Pregnancy : All women should be screened for syphilis with a non Treponemal test – RPR / VRDL – early in pregnancy and preferably again at delivery . In high risk areas testing at the beginning of 3rd Trimester is also recommended. All Positive tests should be confirmed with a Treponemal test FTS-ABS /TPPA. For women treated during pregnancy FU serology testing is necessary to assess efficacy of therapy. Treatment with penicillin is the gold standard.
Maternal Syphilis Dx and treatment • A single dose of Benzathine Penicillin therapy for early disease is only appropriate when is possible to document that there was a non reactive Syphilis test within the last Year. • Some Give a second dose of Benzathine Penicillin 1 week after the first to improve the likelihood of a serology response in early disease. • In all other cases the disease should be consider Latent syphilis of unknown duration for which 3 doses of Benzathine penicillin at weekly intervals are recommended. • Follow up titers at 1,3,6,12 and 24 months decreases fourfold by 6 months and becomes negative by 12-24 months. Failure to decrease titers is likely to be failure to treat or reinfection.
Evaluation of Newborn with Congenital Syphilis • Mother’s serological status for syphilis • Blood cord testing is inadequate for screening (could be non-reactive even when the mother is +) • Infants born from seropositive mothers require a careful examination and a quantitative non-treponemal test (same test should be performed to the mother) • If maternal titers have increased to > 4 folds and/or infant’s titer is 4 fold greater than the mother’s titers complete workup is warrant.
Evaluation of Newborn with Congenital Syphilis • Untreated, inadequately treated, or treatment not documented • Treated with a non-penicillin regimen (i.e.,erythromycin) • Appropriately treated with PNC, but without the expected decrease in treponemal titers • Syphilis treated < 1 month prior to delivery • Syphilis treated before pregnancy but with insufficient serologic f/u to assess response
Evaluation of Newborn with Congenital Syphilis -work up- • Physical Examination • Quantitative non-treponemal serologic test of serum from the infant for syphilis (not from cord blood) • VDRL and cell count from CSF • Long bone X-rays (unless Dx established otherwise) • Complete blood cell and platelet count • Other tests include: • Chest X-ray • LFT • Pathological examination of placenta or umbilical cord using specific fluorescent antitreponemal antibody staining • Vision and hearing test
Evaluation of Newborn with Congenital Syphilis Transplacental transmission of nontreponemal and treponemal antibodies to the fetus can occur in a mother who has been treated appropriately for syphilis during pregnancy, resulting in + uninfected newborns, usually reverting by 4 to 6 months of age, whereas + FTA-ABS or TP-PA test result from passively acquired Ab and it may not become negative for 1 year or longer.
Congenital Syphilis Hydrops fetalis Nasal discharge Petechial rash Necrotizing funisitis within the matrix of the umbilical cord Hepatomegaly Rash Ostitis , Metaphysitis, Periostitis Wimberger sign
Decreased mineralization of the metaphyses of long bones of the upper extremities bilateral lytic lesions of the talus, calcaneous, and proximal tibia (Wimberger sign) medially A more specific finding is localized bony destruction of the medial portion of the proximal tibial metaphysis (Wimberger’s sign). Other findings include metaphyseal serration (“sawtooth metaphyses”), and diaphyseal involvement with periosteal reaction. Radiografic Abnormalities
Dermatology finding Congenital Syphilis Dermatological findings are quite variable, although palmar/plantar, perioral, and anogenital regions are classically described as being involved. The images to the left demonstrate findings at birth in an affected infant, with a desquamating eruption that was widespread over the entire body. These lesions are extremely infectious. Because of the variable lesions and clinical symptoms seen with CS, it has frequently been termed "the great imitator", and it is important to consider alternative diagnoses or vesiculobullous diseases that involve the palms and soles.
CDC guideline 2006 Congenital Syphilis Scenario 1. Infants with proven or highly probable disease and -an abnormal physical examination that is consistent with congenital syphilis, -a serum quantitative nontreponemal serologic titer that is fourfold higher than the mother’s titer,§ or -a positive dark field or fluorescent antibody test of body fluid(s). Recommended Evaluation CSF analysis for VDRL, cell count, and protein¶ CBC and PLT Other tests as clinically indicated (e.g., long-bone radiographs, chest radiograph, liver-function tests, cranial ultrasound, ophthalmologic examination, and auditory brainstem response) Recommended RegimensAqueous crystalline penicillin G 100,000–150,000 units/kg/day, administered as 50,000 units/kg/dose IV every 12 hours during the first 7 days of life and every 8 hours thereafter for a total of 10 days OR Procaine penicillin G 50,000 units/kg/dose IM in a single daily dose for 10 days
CDC guideline 2006 Congenital Syphilis • Scenario 2. Infants who have a normal physical examination and a serum quantitive nontreponemal serologic titer the same or less than fourfold the maternal titer and the -mother was not treated, inadequately treated, or has no documentation of having received treatment; -mother was treated with erythromycin or other nonpenicillin regimen;** or -mother received treatment <4 weeks before delivery. Recommended Evaluation • CSF analysis for VDRL, cell count, and protein -CBC and PLT -Long –bone RX Recommended RegimensAqueous crystalline penicillin G 100,000–150,000 units/kg/day, administered as 50,000 units/kg/dose IV every 12 hours during the first 7 days of life and every 8 hours thereafter for a total of 10 days ORProcaine penicillin G 50,000 units/kg/dose IM in a single daily dose for 10 days OR Benzathine penicillin G 50,000 units/kg/dose IM in a single dose • Some specialists prefer the 10 days of parenteral therapy if the mother has untreated early syphilis at delivery
CDC guideline 2006 Congenital Syphilis • Scenario 3. Infants who have a normal physical examination and a serum quantitative nontreponemal serologic titer the same or less than fourfold the maternal titer and the • mother was treated during pregnancy, treatment was appropriate for the stage of infection, and treatment was administered >4 weeks before delivery; and • mother has no evidence of reinfection or relapse. • Recommended EvaluationNo evaluation is required. • Recommended RegimenBenzathine penicillin G 50,000 units/kg/dose IM in a single dose
CDC guideline 2006 Congenital Syphilis • Scenario 4. Infants who have a normal physical examination and a serum quantitative nontreponemal serologic titer the same or less than fourfold the maternal titer and the -Mother’s treatment was adequate before pregnancy, and -mother’s nontreponemal serologic titer remained low and stable before and during pregnancy and at delivery (VDRL <1:2; RPR <1:4). • Recommended EvaluationNo evaluation is required. • Recommended RegimenNo treatment is required; however, some specialists would treat with benzathine penicillin G 50,000 units/kg as a single IM injection, particularly if follow-up is uncertain.
Congenital Syphilis • Conclusions The incidence of congenital syphilis corresponds to the incidence of disease in women. All pregnant women should be tested 1st trimester and in the beginning of 3rd Trimester and at delivery. All positive test should be confirmed with a Treponemal Test , treat and follow up titers as per protocol. Documentation is an important aspect in the evaluation of treatment.
