GENERAL CONSIDERATIONS CHLAMYDIA & GONORRHEA UNTREATED CT/GC INCREASE A WOMAN’S RISK OF: PID, ECTOPIC PREGNANCY, TUBAL INFERTILITY, CHRONIC PELVIC PAIN ~8% INCREASED RISK OF INFERTILITY ESP. WITH GC ~5% OR LESS RISK OF INFERTILITY WITH CT DEPENDS ON THE NUMBER OF EPISODES OF PID

STD UPDATE PER MATT GOLDEN, MD, MPH – MEDICAL DIRECTOR, PHSKC STD CLINIC 6% (may be higher now) RESISTANCE TO QUINOLONES FOR GC TX – DON’T USE. TX WITH AZITHROMYCIN 1 GM WILL TREAT 90% OF GC CASES
PDPT RECOMMENDATIONS (PATIENT DELIVERED PARTNER THERAPY) PDPT REDUCES RE-INFECTION RATES! A GOOD FAITH EFFORT TO ASSURE PARTNER TX IS THE DIAGNOSING CLINICIAN’S RESPONSIBILITY IF UNABLE/UNWILLING – DOH WILL ASSUME RESPONSIBILITY NO NATIONAL GUIDELINES FOR PDPT PDPT IS LEGAL IN WA AND OR MEDICATION SHOULD BE DISPENSED WITH INFORMATION ABOUT DRUG ALLERGIES/SE’S
LEGAL STATUS OF PDPT IN WA STATE When Chlamydia & gonorrhea are identified in a pt. The adequate treatment and prevention of recurrence in the patient often depends on the treatment of the partner or partners who may not be available or agreeable to direct examination. The Medical Commission recognizes that it is a common practice for health care practitioners to provide antibiotics for the partner(s) without prior examination. While this is not the ideal in terms of the diagnosis and control or Chlamydia and gonorrhea, the Medical Commission recognizes that this is often the only reasonable way to access and treat the partner(s) and impact the personal and public health risks of continued, or additional, Chlamydia and gonorrheal infections. The Medical Commission urges practitioners to use all reasonable efforts to assure that appropriate information and advice is made available to the absent treated third party. MEDICAL QUALITY ASSURANCE COMMISSION POLICY STATEMENT – NOV. 2003
PDPT RECOMMENDATIONS WA STATE DOH 2004 “The provider should inform the patient that it would be best to have all partners exposed during the previous 60 days to come into a clinic for examination, testing and treatment. However, if treatment is not otherwise assured, the patient should be provided antibiotics for their partner(s). These medications must include appropriate written information for the treated third party.” CDC 2005 “CDC has concluded that expedited partner therapy is a useful option to facilitate partner management.”
Recurrent Gonorrhea & Chlamydia Infection in absence of PDPT CT: 12.6% of men 13.3 % of women GC: 9.4% of men 11.7 % of women This is why we must be vigilant about treating sexual partners!
King County DOH provided partner meds In King Co. the DOH provides packets for treatment of sexual partners. Includes medication, information, condoms Provide required written information for the SP (med. side effects, allergies, tx without exam, f/u) Meds for CT, GC or both List of certain pharmacies which have partner meds if clinic does not provide Currently available services outside of King Co. (Snohomish county)
Rescreening for CT & CG Whenever possible, women should be re-screened for CT 3-5 mo after original tx Test of cure is not indicated except in pregnant women or if using alternative treatment recommendation d/t pt allergy or other CI. Rescreening can be done on a urine specimen While limited data are available, existing data support re-screening in men for GC in addition to CT Do NOT re-test sooner than 3 wks. after treatment. Will get false positive.
SYPHILIS Increase in syphilis in MSM in every major city in the world! Significant decrease in all STD’s during the early 80’s with HIV awareness Remained low(er) until ~’99 when rise began Startling increase seen in ’05, ’06 especially in syphilis in MSM Also increasing in the heterosexual pop. Geographic differences. Southern states greater incidence Af. Am > Cauc. Have high index of suspicion
Testing RPR, VDRL – screening, non-specific FTA, TPPA – specific treponemal tests for confirmation
PHSKC STD/HIV Screening Guidelines for MSM Sex with other men in past 12 mo. HIV serology, if HIV neg or not prev. tested Serology test for syphilis Pharyngeal GC culture Receptive anal sex in past 12 mo Rectal GC culture Rectal CT culture Repeat testing in 2-6 mo if: Crystal meth Bacterial STD Unprotected anal sex with partner of unknown or discordant HIV status
Syphilis Primary, Secondary, Early Latent Recommended regimen Benzathine Penicillin G, 2.4 million units IM Penicillin Allergy* Doxycycline 100 mg twice daily x 14 days or Ceftriaxone 1 gm IM/IV daily x 8-10 days (limited studies) or Azithromycin 2 gm single oral dose (preliminary data) *Use in HIV-infection has not been studied
Primary/Secondary Syphilis Response to Treatment No definitive criteria for cure or failure are established Re-examine clinically and serologically at 6 and 12 months Consider treatment failure if signs/symptoms persist or sustained 4x increase in nontreponemal test Treatment failure: HIV test, CSF analysis; administer benzathine pcn weekly x 3 wks Additional therapy not warranted in instances when titers don’t decline despite nl CSF and repeat therapy
Syphilis Latent Syphilis Recommended regimen Benzathine penicillin G 2.4 million units IM at one week intervals x 3 doses Penicillin allergy* Doxycycline 100 mg orally twice daily or Tetracycline 500 mg orally four times daily Duration of therapy 28 days; close clinical and serologic follow-up; data to support alternatives to pcn are limited
Syphilis Management of Sex Partners At risk- 3 mo + sx for primary, 6 mo + sx for secondary, one yr for early latent Exposure to primary, secondary, or early latent within 90 days, tx presumptively Exposure to primary, secondary, or early latent > 90 days, tx presumptively if serology not available Exposure to latent syphilis who have high nontreponemal titers > 1:32, consider presumptive tx for early syphilis
STD PREVENTION Condoms effective in decreasing but not eliminating infection. Overall ~80% effective in preventing STD’s Studies vary, but none show NO effectiveness! Evidence of regression and clearance of HPV with consistent condom use!
Summary – Condom Efficacy HIV - decreased by 80-95% CT, GC - decreased by ~ 50% HSV II - decreased by 30-70% Vag. Inf. (BV, VVC) - modest decrease Syphilis - decreased by ~25% HPV - decreased by 80% (study in progress)
Abstinence & Sex Education Few experimentally evaluated interventions Programs that promote abstinence and consistent contraceptive use can delay first sex While some educational interventions appear to be efficacious, effect sizes tends to be small and the impact is not sustained. By 1 yr post intervention, the effect seems to be gone
So….What’s New in STD’s? QRNG is on the rise – particularly among MSM - Higher dose of Ceftriaxone IM new recommendation. - Presumptive treatment for CT in pts with pos GC, despite negative screen. PDPT proven to reduce recurrence rate of GC/CT Rescreening for GC & CT should be routine STD epidemic in MSM continues Condoms are highly effective – but not perfect Abstinence is efficacious but temporary!
HSV – 2 . Chronic suppressive Rx prevents transmission HPV vaccine very effective. Two options available (Gardasil and Cervarix)
