Disclosures • No commercial disclosures • Dakota AIDS Education & Training Center
Learning Objective • At the end of the presentation, participants should be familiar with basics of: • Common Sexually Transmitted Infections • 2010 CDC STD Treatment Guidelines • Common presentations of HIV • HIV Screening
What is Your Professional Discipline? • Nurse • Physician • Public Health (RN, Epidemiologist) • Allied Health • Laboratory • Social Worker • Other
Overview • Sexually Transmitted Infections • Case # 1 • Case # 2 • Case # 3 • Case # 4 • Summary
Sexually Transmitted Infections • Common • Wide variety of pathogens can be transmitted sexually • Often transmit more efficiently male→female than female→male • Sequelae • Direct effect of pathogen on body • Infertility, ectopic pregnancy, cancer, transmission to fetus
Some (not all) Pathogens Transmitted Sexually • T. pallidum (Syphilis) • Neisseria gonorrhoeae • Chlamydia trachomatis • Ureaplasmaurealyticum • Mycoplasma genitalium • Haemophilusducreyi (Chancroid) • Chlamydia trachomatis L1, L2, L3 (Lymphogranulomavenereum) • Klebsiellagranulomatis (Granuloma Inguinale) • Trichomonasvaginalis • Scabies, Pediculosis pubis • HSV, Herpes Simplex Virus • HIV • HBV, HDV • CMV, EBV • Human Papilloma Virus (HPV) • HHV-8, Kaposi’s Sarcoma Herpes Virus (KSHV)
Overview • Sexually Transmitted Infections • Case # 1 • Case # 2 • Case # 3 • Case # 4 • Summary
Case #1 • 19 year-old female student presents for routine care • Sexually active with male partner • Feels well, no GU symptoms • Cervical swab • Routine pap smear • Chlamydia/Gonorrhea Nucleic Acid Amplicification Test (NAAT) • Chlamydia NAAT returns positive
How should she be treated? • Ceftriaxone 250 mg IM x 1 dose • Azithromycin or doxycycline for patient • Azithromycin or doxycycline for both patient and her partner • Cipro 500 mg PO BID x 7 days • Confirm NAAT with culture prior to treatment
Chlamydia • Chlamydia trachomatis • Most common bacterial STI • Often asymptomatic • Can give urethritis in men • Common cause of infertility • Scarring of fallopian tube (Pelvic Inflammatory Disease) • 10-15% of women with untreated Chlamydia develop PID • Women often re-infected if partner not treated • Treat with azithromycin or doxycycline • Sexually active women need yearly Chlamydia/gonorrhea testing
Observed Single dose treatment advantage • treatment completed • No sexual intercourse for 7 days after treatment completed • Test of cure not recommended • 3 month re-testing recommended to screen for re-infection
How should her sexual partner be managed? • Timely treatment of sexual partner important to reduce risk of re-infecting index patient, others • Instruct patient to refer most recent sexual partner, and any other partners within 60 days of Chlamydia diagnosis, for testingand treatment • If sexual partner(s) unlikely to present for treatment, consider Expedited Partner Therapy • Patient must inform partner, provide written material to seek evaluation for symptoms of complications (testicular pain, pelvic pain) • Patient-delivered prescription or antibiotic for partner(s) • Not for Men who have sex with Men (MSM) • Very high HIV risk, partners need testing/treatment
Overview • Sexually Transmitted Infections • Case # 1 Chlamydia • Case # 2 • Case # 3 • Case # 4 • Summary
Case #2 • 28 year old man presents with painful, burning urination x 1 week • Yellow urethral discharge x 3 days • “I’ve never had this before!” • Reports 3 female sexual partners in last several months • Intermittent condom use, only when partner is new
Public Health Image Library • Urethral swab taken • Gram stain • Gram Negative Diplococci
Likely etiology of urethritis? Chlamydia Herpes Simplex Virus Gonorrhea E. coli UTI/ epididymitis Syphilis
How should this be treated? • Ceftriaxone 250 mg IM x 1 • Ceftriaxone 250 mg IM + Azithromycin 1g PO x 1 • Doxycycline 100 mg PO BID x 7 days • Ciprofloxacin 500 mg PO BID x 7 days • Cefixime 400 mg PO x 1
Gonorrhea • Neisseria gonorrhoeae • 700,000 cases/year in U.S. • Men: urethral discharge, urethritis • Women: asymptomatic, dysuria, vaginal discharge, PID • Diagnosis: • Gram Stain • Culture: Thayer-Martin media or chocolate agar • NAAT on urine, urethral swab, cervical swab • Will transmit to infant during birth
Provide treatment for Chlamydia together with Gonorrhea • Common co-infections • Cipro/Levofloxacin resistent Gonorrhea now common • Resistance to Cephalosporins rare but expected to increase • Routine test of cure not recommended (only if symptoms) • Rescreen at 3 months to detect re-infection
Overview • Sexually Transmitted Infections • Case # 1 Chlamydia • Case # 2 Gonorrhea • Case # 3 • Case # 4 • Case # 5 • Summary
Case # 3 • 32 year old man presents with ulcer on penis • Does not hurt, present for 1 week • Married, wife doesn’t have any symptoms • Travels frequently for business • several sexual encounters per year with other men • 2 years ago • Treated for gonorrhea • HIV test negative at that time • Uses condoms “most of the time”
Most likely etiology of penile ulcer? • Herpes Simplex Virus • Syphilis • Gonorrhea • Chlamydia • Lymphogranuloma Venereum (LGV)
Syphilis • Treponemapallidum • 36,000 cases/year in U.S. • 2/3 in MSM • A systemic disease • Primary: painless genital ulcer (chancre) • Secondary: rash • Latent • asymptomatic at first • neurologic, bone, heart disease in 10-20 years • Pregnancy: transmission to infant • Diagnosis: RPR or VDRL blood test • All patients with Syphilis need HIV testing! • All partners need evaluation, usually presumptive treatment
Primary and secondary syphilis • Benzathine PCN G 2.4 Million Units IM x 1 dose • Latent Syphilis • Early: Benzathine PCN G 2.4 Million Units IM x 1 dose • Late, or unknown duration: Benzathine PCN G 2.4 Million Units IM x q week x 3 doses • Tertiary: cardiac, Gumma (need to rule out Neurosyphilis) • Benzathine PCN G 2.4 Million Units IM x q week x 3 doses • Neurosyphilis • Penicillin G 24 million units/day (continuous IV infusion) x 10-14 days
