Updates in STD Management Jessica Lee Howell, MD Swedish First Hill Family Medicine Residency Infectious Diseases in Primary Care CME Conference May 9, 2014
Objective Questions • How are we doing as a nation in screening and managing STDs? • Who is at risk for STDs in our community? • What are the screening recommendations? • What resistance issues are concerning? • What are the current treatment guidelines? • What are some special cases we may encounter?
STDs: National Report Card • Chlamydia >1.4 million cases in 2012 • largest number of cases ever reported to CDC for any condition • # of cases in women unchanged • Gonorrhea 335,000 cases in 2012 • 74% decline from 1975-1997 • rates steadily increasing since 2009
STDs: National Report Card • Syphilis 16,000 cases in 2012 • Congenital syphilis cases decreasing • Cases among men, especially MSM rising • HIV 50,000 new cases in 2012 • 1 in 6 unaware of their infection • 2/3 new infections among MSM
Screening Recommendations High Risk = H/o STDs, new or multiple sexual partners, inconsistent condom use, exchanging sex for money or drugs
STD Treatment • Of course, there’s an app! App: STD Tx Guide
Gonorrhea: Treatment Update • Treat with CTX + Azithromycin or Doxycycline • If signs of treatment failure on CTX, TOC by culture and report to KC PH: (206) 744-2275 • If alternate therapy, TOC by culture after 1 week at infected anatomic site -> CTX 250mg IM + Azithro 2g PO if positive. • King County: If culture unavailable, refer to KC PH for testing or NAAT ok
Gonorrhea: New Therapy Options 1. Injectable gentamicin + PO Azithromycin 2. PO Gemifloxacin + PO Azithromycin • Phase IV clinical trial by CDC/NIH • 400 participants • 100% cure rate for pharyngeal/rectal GC. • 100%, 99.5% cure rate for genital GC • High reported GI side effects
Expedited Partner Therapy • Make every effort to get partners from previous 60 days evaluated and treated • King County: no TOC for Cefixime + Azithromycin (except pharyngeal) • King County: No EPT for MSM • Pharmacies providing free EPT • http://www.kingcounty.gov/healthservices/health/communicable/std/providers/pharmacies.aspx
Chlamydial Resistance • Few case studies • In vitro studies tetracycline, Sulfa resistance • More to come…
Syphilis Resistance • Penicillin G: bacteriocidal, no known resistance (would require multistep mutation) • Macrolides: bacteriostatic • Erythromycin: 1950s • Clindamycin: 1960s • Azithromycin: 1990 • Tetracycline: no known resistance
Quick Case #1: • 32-year old woman • History of CT, treated 2008. Partner treated. • CC: “I got it again” • No symptoms of PID
Quick Case #1: • NAAT negative • Wet mount negative for trichomonas, BV, yeast • What do you do?
Nongonoccal Cervicitis/Urethritis • Most common pathogens: • Chlamydia • HSV • BV • Trichomonas • Candida • Mycoplasma genitalium& hominis • Ureaplasmaurealyticum & parvum • Irritants
Nongonoccal Cervicitis/Urethritis • CDC recommended therapy • Azithromycin 1g PO OR • Doxycycline 100mg PO BID x 7 days • Refer to gynecology if no improvement
Quick Case #2: • 43 year old man • Recent travel to Mexico • Sexual preference: “married” • Returns with painless penile lesion • What do you do?
Primary Syphilis • Ddx: HSV, HIV, Chancroid, non-STD lesion If MSM, other high-risk, clinical primary syphilis or concern for follow-up, treat presumptively.
