CA STD Data and Statistics
Priority Populations Teens & young people Pregnant women Gay/Bi men (MSM) People of color
Testing in STD Care Testing applications Case finding –Asymptomatic (screening) –Symptomatic (diagnostic) Follow-up Guide treatment (HIV resistance testing) Surveillance Types of tests Culture (susceptibility testing) Serologic tests (antibodies in the blood) Molecular-based tests (NAAT) Combo tests –CT/GC –HIV/syphilis –Non-treponemal and treponemal
Testing Approaches In clinic –Clinician-collected –Self-collected Outside the clinic –Collected at lab –Field-based program –Home testing
Provide Those Free Sexual Health Services! Essential Health Benefits related to STD/HIV prevention and care Must be included in all health plans at no cost-sharing to patient –Annual Wellness visit –STD and HIV screening –STD and HIV care –HPV and Hep B Immunizations –Risk Reduction counseling –Pap smears
1. Ask three essential sexual history questions WHO are your partners? WHAT are your sexual and drug use practices? HOW do you try to prevent STDs/HIV? Risk assessment important since many STDs are asymptomatic
2. Screen for Chlamydia and Gonorrhea ALL sexually active adolescent and young women ≤ 25 years Pregnant women Men who have sex with men (MSM) Persons living with HIV Others according to risk CDC 2010 STD Tx Guidelines.
Why screen? Highly prevalent Frequently asymptomatic Reduces transmission Prevents complications HEDIS measure: chlamydia screening in females under 25 years old Standard of care
Sexually Active adolescents & up to age 25 Routine chlamydia and gonorrhea screening Others STDs and HIV based on risk Women over 25 years of age STD/HIV testing based on risk Pregnant women Chlamydia Gonorrhea (<25 years of age or risk) HIV Syphilis serology HepB sAg Hep C (if high risk) Sexually Active adolescents & up to age 25 Routine chlamydia and gonorrhea screening Others STDs and HIV based on risk Women over 25 years of age STD/HIV testing based on risk Pregnant women Chlamydia Gonorrhea (<25 years of age or risk) HIV Syphilis serology HepB sAg Hep C (if high risk) CDC 2010 STD Tx Guidelines

Who is falling through the cracks? Visits that do not require an exam Pregnancy test only Emergency contraception Contraception method follow-up Refills Depo-provera injection
A pelvic exams is not necessary to obtain a chlamydia test Noninvasive samples –Urine –Self-collected vaginal swabs Nucleic acid amplification tests (NAATs) u Highest sensitivity
Major conclusions NAATs recommended for detection of genital tract infections in men and women – with and without symptoms Optimal specimen types are: First catch urine for men Self collected vaginal swabs from women NAATs recommended for: detection of rectal and oropharyngeal infections
CT Test Volume & Prevalence among Females by Age *Quest Diagnostics/Unilab: West Hills/Tarzana, Sacramento, San Jose What about Women over age 25? 50% Test Volume CA FPACT Data, 2006
Which women over age 25 should be screened? Based on risk: –Infection with CT or GC in past 2 years –> 1 sex partner in past 12 months –New partner in past 3 months –Belief that a partner in the past 12 months may have had other sex partners at the same time Other indications: –Pregnancy –Contact to STD –New STD diagnosis CA CT Screening Guidelines Draft; Howard et al. Over 20. In prep.
STI Screening Recommendations: HIV-positive Men & Women STIAnatomic Site ChlamydiaGenital, rectal if exposed GonorrheaGenital, rectal & oral if exposed SyphilisSerology TrichomoniasisWomen only HSV-2Serology Hep B sAgSerology Hep CSerology Primary Care Guidelines for the Management of Persons Infected with HIV: 2009 Update by the HIVMA of the IDSA. Clin Infect Dis 2009;49, * Screen at least annually; repeat screening every 3-6 months as indicated by risk. MSM- Consider anal Pap screening Women-Cervical Pap screening; Consider anal Pap if hx of dysplasia. *
STD Screening for MSM HIV Syphilis Urethral GC and CT Rectal GC and CT (if RAI) Pharyngeal GC (if oral sex) HSV-2 serology (consider) Hepatitis B (HBsAg) Anal Pap (consider for HIV+) HIV Syphilis Urethral GC and CT Rectal GC and CT (if RAI) Pharyngeal GC (if oral sex) HSV-2 serology (consider) Hepatitis B (HBsAg) Anal Pap (consider for HIV+) * At least annually, more frequent (3-6 months) if at high risk (multiple/anonymous partners, drug use, high risk partners) CDC 2010 STD Tx Guidelines *
Majority of Rectal Infections in MSM are Asymptomatic Chlamydia n=316 Gonorrhea n=264 Chlamydia n=315 Gonorrhea n=364 Rectal Infections Urethral Infections Asymptomatic Symptomatic Kent, CK et al, Clin Infect Dis July % 84% 42% 10%
Proportion of CT and GC infections MISSED among 3398 asymptomatic MSM if screening only urine/urethral sites, San Francisco, ChlamydiaGonorrhea Marcus et al, STD Oct 2011; 38: 922-4
Chlamydia and Gonorrhea NAA Testing …not FDA-cleared for rectal or pharyngeal specimens but now the preferred testing method over culture Validation procedures can be done by labs to allow use of a non-FDA-cleared test or application Quest & LabCorp currently provide GC/CT NAAT for rectal/pharyngeal specimens
NAAT Laboratory Ordering and Billing Codes *CDC does not endorse these laboratories, however, they represent the largest laboratories nationally. There may be other private laboratories that have verified rectal and pharyngeal testing with NAATs. Many PHLs have also verified rectal and pharyngeal testing. For information on specimen collection and transportation, clinicians should contact the local reference laboratory representative. Bolan, CDC webinar March 2011
Case Scenario 22 year old female Asymptomatic, no prior STDs STD Screening done on intake No known drug allergies GC positive CT negative
What regimen would you use to treat Gonorrhea? A.Ceftriaxone 250 mg IM B.Azithromycin 2 gm PO C. Ceftriaxone 250 mg IM plus azithromycin 1 gm PO D. Ceftriaxone 125 mg IM plus azithromycin 1gm PO
Development of GC Resistance 1930s-1970s1980s1990s2000s2010s 1945: Penicillin first used widely for TX 1936: Sulfanilamides introduced as TX 1989: Penicillin no longer recommended for TX by CDC 1976: Pen-R NG first identified in US (in CA) 1986: GISP started by CDC 2007: Fluoroquinolones no longer recommended for TX by CDC 1991: QRNG first identified in US (in HI) 2002: Fluoroquinolones no longer recommended for TX by CA 2010: Dual TX recommended for TX by CDC 2001: First cephalosporin TX failures in Japan
Who is most likely to be affected by cephalosporin-resistant GC? Men who have sex with men California 30
Gonorrhea Treatment: Uncomplicated Genital/Rectal/Pharyngeal Infections Ceftriaxone 250 mg IM in a single dose Azithromycin 1 g orally ** or Doxycycline 100 mg BID x 7 days PLUS* * Regardless of CT test result MMWR Weekly August 10, 2012 MMWR updates CDC 2010 Guidelines **Azithromycin preferred as 2 nd antimicrobial 3. Use Current Treatment for Gonorrhea
Do you have ceftriaxone and azithromycin available onsite? 1.Yes 2.No
ALTERNATIVE CEPHALOSPORINS: Cefixime 400 mg orally once PLUS Dual treatment with azithromycin 1 g (preferred) or doxycycline 100 mg BID x 7 days, regardless of CT test result IN CASE OF SEVERE ALLERGY: Azithromycin 2 g orally once (Caution: GI intolerance, emerging resistance) Gonorrhea Treatment Alternatives Anogenital Infections MMWR 2012 / 61(31); Proposed in case of allergy: gentamicin 240 mg IM + azithromycin 2g orally or gemifloxacin 320 mg orally + azithromycin 2g orally
Test of Cure Current TOC recommendation: Test of cure in 1 week for anyone treated w/ alternative regimens –Routine TOC poses implementation challenges –No data on TOC positivity rates in absence of symptoms Proposed: Limit TOC only to pharyngeal GC treated with alternative regimen, may extend interval to 14 days
How to slow the spread of A-R Gonorrhea New antibiotics Multiple antibiotics Surveillance –Rapid response plans –Resistance testing of isolates
Suspected GC Treatment Failure What should I do? CDPH Recommendations CULTURE: if GC culture not available on-site, call CA STD Control Branch for resources REPEAT TREATMENT: Ceftriaxone 500 mg IM PLUS Azithromycin 2 g orally in a single dose* REPORT: To your local health department within 24 hours; call STD Control Branch if consult desired TREAT PARTNERS: All partners in last 60 days should be treated with CTX 500 mg + AZ 2g TEST OF CURE (TOC): Patient returns in 1 week for TOC with culture (if culture not avail, with NAAT) * If reinfection suspected instead of treatment failure, OK to repeat treatment with CTX AZ 1g
4. Ensure Partner Management Patient referral Ask patient to notify partner and ensure treatment Suggest patient bring partner to clinic for concurrent treatment (“BYOP”) Internet-based anonymous notification Expedited partner treatment (EPT) Patient-delivered partner treatment (PDPT) Health department field-delivered treatment Pharmacy-based Provider or clinic-based referral Health department referral

Challenges in Managing Vaginitis Patient factors –Self-treatment may preclude diagnosis –Clients seek help from multiple providers Provider factors –Under-utilization of available tests –Insensitive clinic-based tests –Dependent on provider skill s 7. Offer Management for Recurrent/Persistent Vaginitis
Bacterial Vaginosis Decrease in lactobacilli Polymicrobial overgrowth Enzymes degrade the protective effects of cervical mucus and immune factors Photo: Seattle PTC
Bev….. “I have BV again!” Recurrence rates a s high as 30% at 3 months and 80% at 9 months Etiology unclear Resistance? Re-infection? Unrecognized trigger? Failure of lactobacilli to recolonize?

Diagnostic tests for Trichomonas Sekisui Diagnostics –CLIA-waived –Results in 10 minutes –83% sensitive compared to culture BioMed Diagnostics –Needs incubator –Read at 3 and 5 days Gen-Probe APTIMA Trichomonas vaginalis Assay Same specimen types as for other APTIMA tests Close to 100% sensitive; Slightly less sensitive using urine Over 99% specific
Trich in HIV + Women Screen on entry to care Retest at 3 months after treatment Consider metronidazole 500 mg p.o. bid x 7d instead of stat dose
OH, NO!! She’s allergic to metronidazole!
Treatment Options with “Azole” Allergy Consult with specialist –Metronidazole desensitization Helms et al, Am J Obstet Gynecol 2008 Perlman et al, Am J Obstet Gynecol, 1996 Kurohara et al, j Allergy Clin Immunol, 1991 Paramomycin vaginal inserts –not as effective
8. Encourage Good Old Condoms!
Openers for a Conversation about Condoms Tell me about your experience with condoms. Some men take condoms almost for granted, and other men really dislike them. What about you? How willing have you found guys to be about using condoms?
Making the Change Goal: to improve patient care by improving medical practice What can you do on your own? What can you realistically influence? What can you advocate for?
THANK YOU!!!! Questions?

California Laws and Regulations
STD Reporting to Public Health Which diseases? –Syphilis within 1 day –HIV/AIDS –Chlamydia, including LGV –Gonorrhea –Chancroid –Pelvic Inflammatory Disease (PID) By whom? –Provider and Laboratory To whom? The jurisdiction where patient resides How? CMR to be completed by the provider Within 7 days
Partner Management Provider Responsibility The clinician should: – Attempt to determine the source of infection – Determine the intimate and sexual contacts of the infected patient – Make an effort with patient to bring in those contacts for exam and treatment Persons determined as source of infection but not under treatment within 10 days of infection should be reported to the health officer EPT is allowable for CT, GC, and trichomoniasis CCR Title 17 §2636
Minor’s Rights to STD Care in California Minors age 12 and above are able to consent to STD and reproductive health care without parental permission As of January 1, 2012, minors may also consent to medical care related to prevention of STD (e.g., HPV vaccine) Minors have a right to confidentiality Parents are not liable for costs of STD care Reporting requirements for non-consensual (and “unlawful”) sexual activity CA Family Code §6926
Transmission of HSV-2 to Susceptible Partners is Reduced with Once-Daily Suppression Corey et al, NEJM 2004; 350(1): Control Group (N=741) Valacyclovir Group (N=743) 1484 heterosexual couples randomized to 500 mg of valacyclovir vs placebo once daily for 8 months Monthly serum samples collected from susceptible partners Valacyclovir group showed decreased transmission lower frequency of shedding fewer copies of HSV-2 DNA when shedding occurred
Gardasil or Cervarix: Which is better? BOTH HPV Vaccines: Effective in preventing 16/18-related cervical dysplasia Good safety profile High cost –Gardasil advantages: Protects against 6/11-related genital warts Licensed for males Indications vulvar/vaginal dysplasia –Cervarix advantages: Higher titer levels May give greater cross-protection against other oncogenic HPV types Effectiveness data for preventing persistent re-infection
