44
Q

Syphilis
-screening tests

A

**must use two tests (must use both)
1. nontreponemal (VDRL/RPR)
2. treponemal (FTA-ABS; EIA; CIA)
-RPR/VDRL will be positive for life
-treponemal tells you how tx is working (if its eradicating disease)
*if VDRL/RPR (nontreponemal) is positive, but treponemal test is negative, the initial RPR/VDRL is deemed false positive

45
Q

Syphilis
-when do patients have a false positive result?

A

when RPR is positive but the trep confirmatory test is negative

46
Q

Syphilis
-what can cause a false positive test?

A

pregnancy, aging, immunizations (including influenza), lyme disease, Hepatitis, TB, mononucleosis, HIV

47
Q

Syphilis
-annual screening

A
  1. should screen all sexually active patients who have HIV for syphilis => often these coexist together
  2. performed at first prenatal visit; if high risk, test TWICE in third trimester (28 weeks and at delivery)
  3. screening men who have sex with men can be conducted annually
48
Q

how often should pregnant women be tested for syphilis?

A

first prenatal visit; if high risk, test TWICE in third trimester (28w and at delivery)

49
Q

Syphilis
-tx

A

first line: penicillin (used in all stages of syphilis)
*preparation, dosage, and length of tx depends on stage and clinical manifestations of disease. Use Trep test to tell you range, titers - this correlates to stage pt is in.

-pregnant women at any stage of syphilis w/ penicillin allergy should be desensitized and treated with penicillin

50
Q

desensitization therapy

A

-used for people with penicillin allergy (important in pts needing tx for syphilis)
-admit pt to hospital; receive penicillin but closely watched by medical staff in order to recieve it

51
Q

Jarish-Herxheimer Reaction

A

acute febrile rxn frequently accompanied by HA, myalgia, fever that occurs w/i 24 hours after any initiation of syphilis therapy
-THIS IS NOT A RXN TO PEN
-inform patient of this possible rxn and how to handle it if it occurs (antipyretics)
-most frequently seen in early syphilis because the bacterial loads are much higher during these stages
*this rxn might induce early labor or cause fetal distress in pregnant women; this should not prevent or delay therapy

52
Q

Syphilis
-partner tx

A

-persons who have had sex w/ a pt who received a dx of syphilis, less than 90d before the dx should be treated presumptively for early syphilis even if serologic tests results are negative
-persons who have had sex w/ a pt who received a dx of syphilis, more than 90d before dx, should be treated presumptively for early syphilis if serologic tests results are not immediately available and opportunity for F/U is uncertain
*if serologic tests are negative, no tx is needed
*if serologic tests are positive, tx should be based on the clinical and serologic evaluation and syphilis stage
