1 Focused Issue of This Month Treatment and Management of Sexually Transmitted Diseases Tak Kim, MD Department of Obstetrics and Gynecology, Korea University College of Medicine E - mail : tkim@kumc.or.kr J Korean Med Assoc 2008; 51(10): Abstract Sexually transmitted diseases (STDs) are the most common group of identifiable infectious diseases in many countries. Adolescents and young adults (15-24 years old) comprise only 25% of the sexually active population but represent almost 50% of all newly acquired STDs. In a law for prevention of infectious diseases in Korea, STDs include syphilis, gonorrhea, chancroid, nongonococcal urethritis, clamydial infection, genital herpes, and genital wart. Bacterial vaginosis, trichomoniasis, candidiasis, amebiasis, scabies, phthiriasis, granuloma inguinale, AIDS, and high risk human papilloma virus are also included in the STDs. Individuals infected with STDs are 5-10 times more likely than uninfected individuals to acquire or transmit HIV through sexual contacts. Their control is important considering the high incidences of acute infections, complications, and sequelae, their socioeconomic impact, and their role in increasing transmission of the HIV. The purpose of this paper is to summarize the treatment and management of STDs on the basis of Centers for Disease Control and Prevention treatment guidelines for sexually transmitted diseases published in Keywords: Sexually transmitted disease; Treatment; Management 884

2 Treatment and Management of STD Table 1. Recommended regimens for chancroid* Azithromycin 1 g orally in a single dose Ceftriaxone 250 mg intramuscularly(im) in a single dose Ciprofloxacin 500 mg orally twice a day for 3 days Erythromycin base 500 mg orally three times a day for 7 days * Ciprofloxacin is contraindicated for pregnant and lactating women. Azithromycin and ceftriaxone offer the advantage of single-dose therapy. Worldwide, several isolates with intermediate resistance to either ciprofloxacin or erythromycin have been reported. Table 2.

Treatment regimens for uncomplicated gonococcal infections of the cervix, urethra, and rectum Ceftriaxone 125 mg IM in a single dose Cefixime 400 mg orally in a single dose Ciprofloxacin 500 mg orally in a single dose Ofloxacin 400 mg orally in a single dose Levofloxacin 250 mg orally in a single dose PLUS Treatment for chlamydia if chlamydial infection is not ruled out Spectinomycin 2 g in a single IM dose Single-dose cephalosporin regimens (other than ceftriaxone 125 mg IM and cefixime 400 mg orally) that are safe and highly effective against uncomplicated urogenital and anorectal gonococcal infections include ceftizoxime (500 mg, administered IM), cefoxitin (2g, administered IM with probenecid 1 g orally), and cefotaxime (500 mg, administered IM). None of the injectable cephalosporins offer any advantage over ceftriaxone. Single-dose quinolone regimens include gatifloxacin 400 mg orally, norfloxacin 800 mg orally, and lomefloxacin 400 mg orally. These regimens appear to be safe and effective for the treatment of uncomplicated gonorrhea, but data regarding their use are limited. None of the regimens appear to offer any advantage over ciprofloxacin, ofloxacin, or levofloxacin, and they are not effective against QRNG. Table 17.

11 Kim T Table 21. Treatment regimens for external genital warts Patient - Applied: Podofilox 0.5% solution or gel. Patients should apply podofilox solution with a cotton swab, or podofilox gel with a finger, to visible genital warts twice a day for 3 days, followed by 4 days of no therapy. This cycle may be repeated, as necessary, for up to four cycles. The total wart area treated should not exceed 10cm 2, and the total volume of podofilox should be limited to 0.5 ml per day. If possible, the health-care provider should apply the initial treatment to demonstrate the proper application technique and identify which warts should be treated. The safety of podofilox during pregnancy has not been established Imiquimod 5% cream. Patients should apply imiquimod cream once daily at bedtime, three times a week for up to 16 weeks. The treatment area should be washed with soap and water 6~10 hours after the application. The safety of imiquimod during pregnancy has not been established. Provider- Administered: Cryotherapy with liquid nitrogen or cryoprobe. Repeat applications every 1~2 weeks. Podophyllin resin 10~25% in a compound tincture of benzoin. A small amount should be applied to each wart and allowed to air dry. The treatment can be repeated weekly, if necessary. To avoid the possibility of complications associated with systemic absorption and toxicity, two important guidelines should be followed: 1) application should be limited to <0.5mL of podophyllin or an area of <10cm 2 of warts per session, and 2) no open lesions or wounds should exist in the area to which treatment is administered. Some specialists suggest that the preparation should be thoroughly washed off 1~4 hours after application to reduce local irritation. The safety of podophyllin during pregnancy has not been established. Trichloroacetic acid (TCA) or Bichloroacetic acid (BCA) 80~90%. A small amount should be applied only to the warts and allowed to dry, at which time a white frosting develops. If an excess amount of acid is applied, the treated area should be powdered with talc, sodium bicarbonate (i.e., baking soda), or liquid soap preparations to remove unreacted acid. This treatment can be repeated weekly, if necessary. Surgical removal either by tangential scissor excision, tangential shave excision, curettage, or electrosurgery Intralesional interferon Laser surgery Table 22. Treatment regimens for scabies Permethrin cream (5%) applied to all areas of the body from the neck down and washed off after 8~14 hours Ivermectin 200ug/kg orally, repeated in 2 weeks Lindane (1%) 1 oz. of lotion or 30 g of cream applied in a thin layer to all areas of the body from the neck down and thoroughly washed off after 8 hours ~ - 894
