Tests for syphilis : 

Tests for syphilis Dark-field microscopy Treponema pallidum identified from Primary Secondary Early congenital syphilis Method Sore cleaned with saline Dry and crusted lesions Scrape with currete Clear serum obtained (no red cells) Microscopy

Serological tests : 

Serological tests Two types Non-treponemal tests Specific treponemal tests

Serological tests : 

Serological tests Non-treponemal tests Ab to lipoidal material Response to treatment Venereal disease research laboratory (VDRL) Unheated serum reagin (USR) test Rapid plasma reagin (RPR) test Toluidine red unheated serum test (TRUST)

VDRL Test : 

VDRL Test Basis: Flocculation test The patient’s serum mixed in Colloidal solution of cholesterol, lecithin, and cardiolipin If antibodies present Precipitate occurs After treatment Titer will drop over months Indications Screening and monitoring of therapy Evaluation Highly sensitive test 100% positive in secondary syphilis

VDRL Test : 

VDRL Test Disadvantages 10–20% false-positive results positive test must be confirmed False-positive reactions: Diabetes mellitus cirrhosis Autoimmune diseases (lupus erythematosus, systemic sclerosis, rheumatoid arthritis), viral diseases (HIV, measles, mumps, even herpes genitalis) Pregnancy

Serological tests : 

Serological tests Treponemal antigen tests Confirmatory Detect antibodies to Epitope of treponemes Once positive, remain positive for life T. pallidum immobilization (TPI) test Fluorescent treponemal antibody absorption test (FTA-ABS) Treponema pallidum haemagglutination assay (TPHA) Enzyme immunoassay (EIA)

TPI test : 

TPI test Basis Serum containing ab In the presence of complement Inhibits movements of T. Pallidum Observed by dark-field microscopy Gold standard Due to high specificity

TPHA test : 

TPHA test Basis: Sheep erythrocytes coated with Treponema pallidum antigens Incubated with patient serum If antibodies present Red cells agglutinate Indications: Screening. Evaluation: Highly specific; False positive under 0.1% Becomes positive in third week Remains positive for life of patient

Screening : 

Screening Screening either EIA VDRL/TPHA If positive Confirm with specific test

Examination of CSF : 

Examination of CSF Indications Neurological Treatment failure HIV infection CSF findings of neurosyphilis Mononuclear pleiocytosis Elevated total protein Positive CSF VDRL

Evaluation of neonates : 

Evaluation of neonates Born to seropositive mothers Examination for stigmata X-ray long bones for periostitis CSF examination

Management : 

Management

Management : 

Management Penicillin reactions Jarisch–Herxheimer reaction Within 24 h Acute febrile reaction Headache Myalgia Bone pains Exacerbation of skin lesions

Prognosis : 

Prognosis Early syphilis Cure rate=95% Relapse Retreatment with double penicillin doses is recommended

Thank you

FTA–ABS Test : 

FTA–ABS Test Basis: A slide is coated with Treponema pallidum. Patient’s serum is absorbed with nonpathogenic treponemes and then applied to slide. Antibodies bound to Treponema pallidum are identified with immunofluorescence. Indications: Confirmatory. Evaluation: Becomes positive in fourth week and remains so forever. Advantages: Very sensitive and specific. Disadvantages: Standardized reagents not available so reproducibility varies.

IgM–FTA–ABS Test : 

IgM–FTA–ABS Test Basis: Same as FTA–ABS test, but only labeled anti-IgM antibodies are used to determine if patient has IgM antibodies against Treponema pallidum. Indications: Early diagnosis: IgM antibodies are the first to be produced; they can be found at 2weeks, before a chancre appears. Assessing disease activity: IgM production continues as long as living Treponema pallidum are present in body, so one can determine if latent phase is present or not. Evaluating therapy: The IgM–FTA–ABS test usually turns negative 1month after therapy; always within 1year

IgM–FTA–ABS Test : 

IgM–FTA–ABS Test Diagnosis of congenital syphilis: IgM cannot cross the placenta, so if the infant has IgM antibodies, Treponema pallidum has crossed the placenta. Recognition of second infection: Increase in IgM antibodies coupled with VDRL titer increase suggests second infection without clinical signs. Advantages: Very sensitive and specific. False-positive reactions: Rheumatoid factor is an IgM antibody whose Fc portion is directed against IgG. If the patient has a positive rheumatoid factor and treated syphilis, then persistent IgG antibodies will bind to treponemes on the slide; rheumatoid factor molecules bind to them and are identified by the labeled anti-IgM.

19S–IgM–FTA–ABS Test : 

19S–IgM–FTA–ABS Test Basis: If a patient has a large amount of IgG antibodies against Treponema pallidum and only a small amount of IgM, then the IgG can block the test treponemes on the slide, giving a false-negative test for IgM. To correct this, the 19S fraction of serum where IgM is found is separated out and only this portion used for testing. Indications: Negative IgM–FTA–ABS test but appropriate history.

Evaluation of Serologic Tests : 

Evaluation of Serologic Tests Confirmation of infection with Treponema pallidum: Two positive tests with Treponema pallidum-specific tests. Blood should be re-drawn for the confirmatory testing. An endemic treponematosis must be excluded. Assessing degree of activity: IgM–FTA–ABS becomes negative when Treponema pallidum has been eliminated. VDRL titer 1:64 also suggests active disease. Second infection: Newappearance of IgM antibodies, and rapid increase in VDRL titer by 2 dilutions or more.
