Sexual & Reproductive Health ii.  Alternative regimens: (a) Ampicillin/sulbactam 3 g intravenously every 6 hours plus doxycycline 100 mg intravenously or orally every 12 hours (b) Clindamycin 900 mg intravenously every 8 hours plus gentamicin 2 mg/kg body weight intravenously or intramuscularly for a single dose then 1.5 mg/kg body weight every 8 hours b.  Treatment for M. genitalium should be considered if PID treatment for 7–10 days has failed. Recommended to start moxifloxacin 400 mg orally daily for 14 days. c. Sexual partners of patients with PID within the past 60 days should be tested and treated. Patient Case Questions 11 and 12 pertain to the following case: M.A. is a 24-year-old woman who presents to the emergency department with severe abdominal pain, fever, dysuria, and a vaginal discharge. She is sexually active. Her medical history is unremarkable except for recurrent genital herpes (one or two episodes a year). Her medications on admission include birth control pills (ethinyl estradiol 30 mcg/desogestrel 0.15 mg) and fluticasone nasal spray as needed. On physical examination, M.A.’s vital signs include temperature 101.2°F (38°C), heart rate 92 beats/minute, respiration rate 15 breaths/minute, and blood pressure 117/75 mm Hg. M.A. has adnexal tenderness, cervical motion tenderness, and a vaginal discharge. 11. Which is the best empiric therapy for M.A.? A. Ampicillin/sulbactam intravenously 2 g every 6 hours for 14 days B. Metronidazole 500 mg intravenously three times daily for 7 days C. Cefotetan 2 g intravenously every 12 hours with doxycycline 100 mg orally every 12 hours for 14 days D. Ceftriaxone 125 mg intramuscularly once with doxycycline 100 mg intravenously twice daily for 7 days 12. Which statement is best for M.A. to tell her sexual partners? A. There is no need for concern because this condition is not transmittable to or acquired from a sexual partner. B. Her partner can resume having sexual intercourse with M.A. as soon as her symptoms improve. C. If her partner has had sex with M.A. within the past 60 days, he should be assessed for possible treatment. D. Her partner does not need to be tested for human immunodeficiency virus (HIV) because there is no relationship between HIV and this condition. G. Bacterial Vaginosis 1. Malodorous vaginal discharge caused by an overgrowth of anaerobic bacteria (circumventing the normal flora of Lactobacillus); more than 50% with bacterial vaginosis are asymptomatic. 2. Infection risk is increased in relation to sexual activity, but it is unknown whether acquired through sexual partner. 3. Diagnosis is based on a malodorous vaginal discharge that is high in pH, contains clue cells, and is whiff test positive (fishy odor after potassium hydroxide 10% added to sample). 4. Bacterial vaginosis has been implicated in PID and is possibly linked to endometritis. 5. Treatment a. Nonpregnant women: Metronidazole 500 mg orally twice daily for 7 days or clindamycin 2% cream, 1 full applicator intravaginally at bedtime for 7 days, or metronidazole 0.75% gel, 1 full applicator intravaginally once daily for 5 days ACCP Updates in Therapeutics® 2023: Pharmacotherapy Preparatory Review and Recertification Course 1-614 Sexual & Reproductive Health b. Alternatives: Clindamycin ovules 100 mg intravaginally at bedtime for 3 days, clindamycin 300 mg orally twice daily for 7 days, tinidazole 2 g orally once daily for 2 days, tinidazole 1 g orally once daily for 5 days, secnidazole (Solosec) 2 g packet of granules, sprinkle on pudding, applesauce, or yogurt (do not chew or crush granules, do not dissolve in a liquid) and consume within 30 minutes c. Treatment of sexual partners is not necessary. H. Trichomoniasis 1. Caused by T. vaginalis 2. Men often have no symptoms, but women generally have a malodorous, yellow-green vaginal discharge and vaginal irritation. 3. Diagnosis most sensitive with NAAT, many times detecting five times more T. vaginalis infections than wet-mount microscopy. 4. Treatment a. Recommended treatment for women: Metronidazole 500 mg orally 2 times/day for 7 days b. Recommended treatment for men: Metronidazole 2 g orally in a single dose c. Alternative: Tinidazole 2 g orally in a single dose d. All sexual partners should be treated. e. Metronidazole-allergic patients should be desensitized. I. Vulvovaginal Candidiasis 1. Seventy-five percent of women have at least one episode (40%–45% will have many episodes). 2. Symptoms include pruritus and vaginal discharge. 3. Predisposing factors include OCs, pregnancy, obesity, diabetes mellitus, corticosteroid use, chemotherapy, and antibiotics. 4. Diagnosed by symptoms and potassium hydroxide smear 5. Therapeutic regimens: 1- and 3-day regimens may take up to 7 days for full effect (Table 20). Table 20. Therapeutic Regimens for Treatment of Vulvovaginal Candidiasis Drug Dose Length of Therapy Butoconazole Clotrimazole 2% cream: 5 g intravaginally 1% cream: 5 g intravaginally at bedtime (OTC) 2% cream: 5 g intravaginally at bedtime (OTC) 2% cream: 5 g intravaginally at bedtime (OTC) 4% cream: 5 g intravaginally at bedtime (OTC) 100-mg vaginal suppository at bedtime (OTC) 200-mg vaginal suppository at bedtime (OTC) 1200-mg vaginal suppository × 1 (OTC) 0.4% cream: 5 g intravaginally at bedtime 0.8% cream: 5 g intravaginally at bedtime 80-mg vaginal suppository at bedtime 6.5% ointment: 5 g intravaginally (OTC) 150-mg oral tablet 1 dose 7–14 days 3 days 7 days 3 days 7 days 3 days 1 dose 7 days 3 days 3 days 1 dose 1 dose 150 mg every 72 hours for 2–3 doses (severe infection) Miconazole Terconazole Tioconazole Fluconazole OTC = over the counter ACCP Updates in Therapeutics® 2023: Pharmacotherapy Preparatory Review and Recertification Course 1-615 Sexual & Reproductive Health 6. Recurrent vulvovaginal candidiasis (three or more episodes a year): Needs prescription drug treatment, not OTC. a. Initial treatment for 7–14 days or fluconazole 100-, 150-, or 200-mg dose every third day for three doses b. Maintenance: Oral fluconazole 100, 150, or 200 mg/week for 6 months c. Consider conditions precipitating recurrent vulvovaginal candidiasis: HIV, diabetes mellitus. d. Oteseconazole 150 mg capsule i. FDA approved in 2022 for recurrent vulvovaginal candidiasis in females who are not of reproductive potential. It should only be used in females who are postmenopausal or have permanent infertility (e.g., tubal ligation, hysterectomy, salpingo-oophorectomy). ii. Through a tetrazole metal-binding group, oteseconazole offers greater selectivity for fungal CYP51 than human CYP enzymes and thus causes fewer off-target CYP-induced drug interactions. iii.  Two dosing approaches: (a) Day 1: Oteseconazole 600 mg (single dose); Day 2: oteseconazole 450 mg (single dose); beginning on Day 14: oteseconazole 150 mg once weekly for 11 weeks (weeks 2–12) (b) Days 1, 4, and 7: Fluconazole 150 mg; Days 14–20: oteseconazole 150 mg once daily for 7 days; beginning on Day 28: oteseconazole 150 mg once weekly for 11 weeks (weeks 4–14) iv. Headaches and nausea are most commonly reported adverse effects 7. Prophylaxis needed for vulvovaginal candidiasis while taking antibiotics; recommend OTC 7-day treatment and use a full applicator at bedtime while taking antibiotics; oral fluconazole is also sometimes used. 8. Pregnant women: Drugs of choice are topical azoles, 7-day treatment. XVI. MALE SEXUAL DYSFUNCTION A. Types 1. Reduced libido from organic or psychological causes a.
