Q

Syphilis

DIAGNOSIS / TESTS

A

Serologic Tests:
RPR** + **EIA
need BOTH to confirm disease

RPR = non-treponemal & non-specific
measured titer –> used to monitor TX response or Re-Infection
correlates w/ disease activity
4-Fold Titer change = CLINICALLY SIGNIFICANT
1:2 = lowest

EIA = treponemal & specific
CONFIRMS DISEASE
but is positive for ENTIRE life –> can’t tract treatment progression

Q

LATENT SYPHILIS

Presentation

A
  • Untreated Primary or Secondary Stage*
  • LACKS CLINICAL MANIFESTATIONS*

Detected by:
Serologic Testing = RPR + EIA

EARLY LATENT SYPHILIS
acquired within 12 months & patient remains INFECTIOUS

LATE LATENT SYPHILIS
acquired >1 year or unknown duration
thought to be NON-infectious
Treated like TERTIARY syphilis

Q

Chlamydia Trachomatis

Testing & Follow-Up

A

NAAT
Nucleic Acid Amplification Test
Urine Sample –> 24 hour return
also for RECTAL & OROpharyngeal SWABS

RTC in 3 MONTHS
for ALL, to check for RE-INFECTION (common)
or RTC if sx persist after treatment

PARTNER NOTIFICATION
refer all sex partners in past 60 DAYS

Q

Neurosyphilis

TREATMENT

PCN ALLERGY

A

CSF Evaluation (Lumbar Puncture) –> confirm diagnosis

LIMITED DATA - NO GOOD ALTERNATES

  • *Ceftriaxone 2gm QD IM/IV**

Q

HERPES

Primary Infection

Signs & Symptoms

A

Incubation period b4 onset of lesions = 5 days
w/o tx –> 20-30 day infection

One or MORE blisters
on or around genital area, can break and leave a
PAINFUL SORE
that takes weeks to heal
(Syphilis is only 1 blister and no pain)

1/3 show systemic sxs:
fever / malaise myalgia

1-10% develop:
aseptic meningitis - neck rigidity / HA

Q

HERPES

S/Sx

A
  • *PRODROMAL**
  • *burning / itching / tingling** @ site of infection
  • -> lesion within 12-24hr

TREAT ASAP

  • *Almost ALL persons** w/ symptomatic 1st HSV episode get recurrence of genital lesions
  • *3-4 episodes a year**
  • *Reactivates periodically** caused by factors:
  • *stress / UV light / menses / trauma / illness**

  • *WEEKLY** for 3 WEEKS

if patients MISS >14 days –> START OVER

Q

Neisseria Gonorrhea
Gonococcal Cervicitis

1st Line Treatment

A

CEFTRIAXONE 250mg IM
oral doesnt have high bactericidal levels at anatomic sites
+
Azithromycin 1g
OR
Doxycycline 100mg BID x7days
for Chlamydia coverage

quinolones are RESISTANT now
& resistance to cephalosporins are rising –> surveillance is crucial

Q

What STD has this condition and what is it?

SeroFast

A

SYPHILIS

Pts continue to have low RPR titers d
espite adequate treatment

Q

Syphilis

Epidemiology & Transmission

A
  • *MEN** > Women
  • *MSM epidemic**

Caused by:
Treponema Pallidum = Spirochete

Sexual contact w/ infectious lesions during:
PRIMARY** or **SECONDARY
stages

less common in utero / non-genital body contact w/ infectious lesions / blood borne

Q

SYPHILIS

COUNSELING

A

Important for PARTNERS & INFECTED

Initiate treatment for recurrent disesae
@time of PRODROMAL SXs or 1st Blister

Transmission can occur during ASx periods

NO SEX
when lesions/prodromal Sxs present = highest risk of infection

Q

Neisseria Gonorrhea

Testing & Follow-Up

A

NAAT
Nucleic Acid Amplification Test
Bacterial culture –> ANTIMICROBIAL RESISTANCE TEST

Alternate Regimen** –> **RTC for TEST OF CURE in 14-21 DAYS

PARTNER NOTIFICATION
refer all sex partners in past 60 DAYS

RTC in 3 MONTHS?? - was for Chlamydia
for ALL, to check for RE-INFECTION (common)

Q

Neisseria Gonorrhea

PREGNANCY

Treatment & Special Considerations

A
  • *SAME AS NORMAL TREATMENT**
  • except DOXY is C/I in pregnancy*

CEFTRIAXONE 250mg IM
+

Q

HERPES

Supressive Treatment for Recurrent disease

A

Supressive Therapy –> ↓outbreaks by 70-80%

Frequency & Risk of HSV transmission

  • BUT*
  • *Can result in DRUG RESISTANCE**

Recommended doses:

Q

Neisseria Gonorrhea

Testing Recommendations?

A

CDC Recommendations:

ANNUAL GONORRHEA TESTING FOR:

All Sexually active WOMEN <25yo
(Same as Chlamydia)
commonly co-infected with CHLAMYDIA

18
Q

Late Latent** & **Tertiary Syphilis

TREATMENT

PCN ALLERGY

A

Doxycyline 100mg BID
for 28 DAYS
+ close clinical & serologic follow-up

Late latent
no sxs
+confirmed by RPR + EIA
> 1 year or Unknown

Tertiary Syphilis
CV Complications + Gummatous Lesions
1/3 of patients untreated –> 10-30 years later

19
Q

HERPES

DIAGNOSIS

A

Clinical Diagnosis
most common, just can tell

PCR
is the preferred assay to CONFIRM
but is not often done –> need to scrape base of lesion

Serologic Testing
also available, but seldom used, just tells you if you had it

20
Q

Syphilis

Secondary Stage Presentation

A

Untreated infxn –> hematogenous dissemination
in 4-8 weeks after Chancre appreance

Great Imitator”
Variety of Sxs –> affect many organs

RASH on PALMS & SOLES
is most common, but can occur in other areas

Tongue Lesions** + **ALOPECIA

Lymphadenopathy / low grade fever / weight loss
pain in bone + joints

21
Q

Chlamydia Trachomatis

PREGNANCY

Treatment & Special Considerations

A

Azithromycin 1g Single dose
STILL THE SAME

For Pregnant w/ allergy:

  • *Amoxicillin 500mg TID x7days**
  • Doxycycline & Quinolone (levo) are C/I in pregnancy*

REPEAT NAAT** in **3 WEEKS
to confirm eradication for PREGNANCY:
Still RTC 3 months later & possibly for 3rd trimester
to avoid vertical transmission / neonatal infxn

22
Q

Single - PAINLESS ulcer
stage where spirochetes enter body

Sxs occur ~3 weeks after exposure

Ulcer will heal with scarring 2-8 weeks REGARDLESS of Treatment
