  • Note: Patients should be tested for HIV infection at the time chancroid is diagnosed. If the initial test results were negative, a serologic test for syphilis and HIV infection should be performed 3 months after the diagnosis of chancroid.
  • 1.1 Follow-up
  • Patients should be re-examined 3–7 days after initiation of therapy. If treatment is successful, ulcers usually improve symptomatically within 3 days and objectively within 7 days after therapy. If no clinical improvement is evident, the clinician must consider whether 1) the diagnosis is correct, 2) the patient is coinfected with another STD, 3) the patient is infected with HIV, 4) the treatment was not used as instructed, or 5) the H. ducreyi strain causing the infection is resistant to the prescribed antimicrobial.
  • Clinical resolution of fluctuant lymphadenopathy is slower than that of ulcers and might require needle aspiration or incision and drainage, despite otherwise successful therapy. Although needle aspiration of buboes is a simpler procedure, incision and drainage might be preferred because of reduced need for subsequent drainage procedures.
  • 1.2 Management of sex partners
  • Regardless of whether symptoms of the disease are present, sex partners of patients who have chancroid should be examined and treated if they had sexual contact with the patient during the 10 days preceding the patient’s onset of symptoms.
  • 1.3 Pregnancy
  • Ciprofloxacin presents a low risk to the fetus during pregnancy, with a potential for toxicity during breastfeeding. Alternative drugs should be used during pregnancy and lactation
  • 1.4 HIV Infection
  • Persons with HIV infection who have chancroid should be monitored closely because they are more likely to experience treatment failure and to have ulcers that heal slowly. Persons with HIV infection might require repeated or longer courses of therapy, and treatment failures can occur with any regimen.

  • 4.6 Allergy, Intolerance, and Adverse Reactions

Human papillomavirus

  • Anogenital Warts
  • 1.Preferred regimen for External Anogenital Warts (i.e., penis, groin, scrotum, vulva, perineum, external anus, and perianus)
  • 1.1 Patient-Applied:: Imiquimod 3.75% or 5% cream OR Podofilox 0.5% solution or gel OR Sinecatechins 15% ointment
  • 1.2 Provider-Administered: Cryotherapy with liquid nitrogen or cryoprobe OR Surgical removal either by tangential scissor excision, tangential shave excision, curettage, laser,or electrosurgery OR Trichloroacetic acid (TCA) or Bichloroacetic acid (BCA) 80%-90% solution
  • Note (1): Many persons with external anal warts also have intra-anal warts. Thus, persons with external anal warts might benefit from an inspection of the anal canal by digital examination, standard anoscopy, or high-resolution anoscopy.
  • Note (2): Might weaken condoms and vaginal diaphragms.
  • 2.Alternative Regimens for External Genital Warts
  • 2.1 Urethral Meatus Warts
  • Preferred regimen: Cryotherapy with liquid nitrogen OR Surgical removal
  • 2.2 Vaginal Warts
  • Preferred regimen: Cryotherapy with liquid nitrogen OR Surgical removal OR (TCA OR BCA 80%–90% solution)
  • Note: The use of a cryoprobe in the vagina is not recommended because of the risk for vaginal perforation and fistula formation
  • 2.3 Cervical Warts
  • Preferred regimen: Cryotherapy with liquid nitrogen OR Surgical removal OR (TCA OR BCA 80%–90% solution)
  • Note: Management of cervical warts should include consultation with a specialist.For women who have exophytic cervical warts, a biopsy evaluation to exclude high-grade SIL must be performed before treatment is initiated.
  • 2.4 Intra-anal Warts
  • Preferred regimen: Cryotherapy with liquid nitrogen OR Surgical removal OR (TCA OR BCA 80%–90% solution)
  • Note: Management of intra-anal warts should include consultation with a specialist.
  • 3. Specific considerations
  • 3.1 Follow-up
  • Most anogenital warts respond within 3 months of therapy. Factors that might affect response to therapy include immunosuppression and treatment compliance. In general, warts located on moist surfaces or in intertriginous areas respond best to topical treatment. A new treatment modality should be selected when no substantial improvement is observed after a complete course of treatment or in the event of severe side effects; treatment response and therapy-associated side effects should be evaluated throughout the course of therapy.
  • 3.2 Management of sex partners
  • Persons should inform current partner(s) about having genital warts because the types of HPV that cause warts can be passed on to partners. Partners should receive counseling messages that partners might already have HPV despite no visible signs of warts, so HPV testing of sex partners of persons with genital warts is not recommended.
  • 3.3 Pregnancy
  • Podofilox (podophyllotoxin), Podophyllin, and Sinecatechins should not be used during pregnancy. Imiquimod appears to pose low risk but should be avoided until more data are available.
  • Cesarean delivery is indicated for women with anogenital warts if the pelvic outlet is obstructed or if vaginal delivery would result in excessive bleeding.
  • Pregnant women with anogenital warts should be counseled concerning the low risk for warts on the larynx of their infants or children (recurrent respiratory papillomatosis).
  • 3.4 HIV infection
  • Data do not support altered approaches to treatment for persons with HIV infection.
  • Squamous cell carcinomas arising in or resembling anogenital warts might occur more frequently among immunosuppressed persons, therefore requiring biopsy for confirmation of diagnosis for suspicious cases
  • 3.5 High-grade squamous intraepithelial lesions
  • Biopsy of an atypical wart might reveal HSIL or cancer of the anogenital tract. In this instance, referral to a specialist for treatment is recommended.

Trichomonas vaginalis

  • 1. T. vaginalis infection in adults [8]
  • 2. T. vaginalis infection in pregnant and lactating Women

  • Note (1): Do not breastfeed for 12-24 hrs following Metronidazole and 72 hrs following Tinidazole
  • Note (2): Symptomatic pregnant women, regardless of pregnancy stage, should be tested and considered for treatment. Pregnant women should be advised of the risk and benefits to treatment as infection (definitely) and treatment (possibly)
  • Note (3): Pregnant women with HIV who are treated for T. vaginalis infection should be retested 3 months after treatment.
  • 3. T. vaginalis infection in patients with HIV

  • 1.1 Treatment of uncomplicated P. falciparum malaria
  • 1.1.1 Treat children and adults with uncomplicated P. falciparum malaria (except pregnant women in their first trimester) with one of the following recommended ACT (artemisinin-based combination therapy)
  • Preferred regimen (1): Artemether 5–24 mg/kg/day PO bid AND Lumefantrine 29–144 mg/kg/day PO bid for 3 days.
  • Note: The first two doses should, ideally, be given 8 h apart.

  • Preferred regimen (2): Artesunate 2–10 mg/kg/day PO qd AND Amodiaquine 7.5–15 mg/kg/day PO qd for 3 days
  • Note: A total therapeutic dose range of 6–30 mg/kg/day artesunate and 22.5–45 mg/kg/day per dose amodiaquine is recommended.
  • Dosage regimen based on Body weight (kg)
  • Body weight (kg)-4.5 to < 9- Artesunate 25 mg PO qd AND Amodiaquine 67.5 mg PO qd for 3 days
  • Body weight (kg)-9 to < 18 - Artesunate 50 mg PO qd AND Amodiaquine 135 mg PO qd for 3 days
  • Body weight (kg)-18 to < 36- Artesunate 100 mg PO qd AND Amodiaquine 270 mg PO qd for 3 days

  • 1.1.2 Reducing the transmissibility of treated P. falciparum infections In low-transmission areas in patients with P. falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Preferred regimen: Single dose of 0.25 mg/kg Primaquine with ACT
  • 1.2 Recurrent Falciparum Malaria
  • 1.2.1 Failure within 28 days
  • Note:The recommended second-line treatment is an alternative ACT known to be effective in the region. Adherence to 7-day treatment regimens (with artesunate or quinine both of which should be co-administered with + tetracycline, or doxycycline or clindamycin) is likely to be poor if treatment is not directly observed; these regimens are no longer generally recommended.
  • 1.2.2 Failure after 28 days
  • Note: all presumed treatment failures after 4 weeks of initial treatment should, from an operational standpoint, be considered new infections and be treated with the first-line ACT. However, reuse of mefloquine within 60 days of first treatment is associated with an increased risk for neuropsychiatric reactions, and an alternative ACT should be used.
  • 1.3 Reducing the transmissibility of treated P. falciparum infections In low-transmission areas in patients with P. falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Note: Single dose of 0.25 mg/kg bw Primaquine with ACT
  • 1.4 Treating uncomplicated P. falciparum malaria in special risk groups
  • 1.4.1 Pregnancy
  • First trimester of pregnancy : Quinine AND Clindamycin 10mg/kg/day PO bid for 7 days
  • Second and third trimesters : Mefloquine is considered safe for the treatment of malaria during the second and third trimesters; however, it should be given only in combination with an artemisinin derivative.
  • Note (1): Quinine is associated with an increased risk for hypoglycaemia in late pregnancy, and it should be used (with clindamycin) only if effective alternatives are not available.
  • Note (2): Primaquine and tetracyclines should not be used in pregnancy.
  • 1.4.2 Infants less than 5kg body weight : with an ACT at the same mg/kg bw target dose as for children weighing 5 kg.
  • 1.4.3 Patients co-infected with HIV: should avoid Artesunate + SP if they are also receiving Co-trimoxazole, and avoid Artesunate AND Amodiaquine if they are also receiving efavirenz or zidovudine.
  • 1.4.4 Large and Obese adults: For obese patients, less drug is often distributed to fat than to other tissues; therefore, they should be dosed on the basis of an estimate of lean body weight, ideal body weight. Patients who are heavy but not obese require the same mg/kg bw doses as lighter patients.
  • 1.4.5 Patients co-infected with TB: Rifamycins, in particular rifampicin, are potent CYP3A4 inducers with weak antimalarial activity. Concomitant administration of rifampicin during quinine treatment of adults with malaria was associated with a significant decrease in exposure to quinine and a five-fold higher recrudescence rate
  • 1.4.6 Non-immune travellers : Treat travellers with uncomplicated P. falciparum malaria returning to nonendemic settings with an ACT.
  • 1.4.7 Uncomplicated hyperparasitaemia: People with P. falciparum hyperparasitaemia are at increased risk of treatment failure, severe malaria and death so should be closely monitored, in addition to receiving an ACT.
  • 2. Treatment of uncomplicated malaria caused by P. vivax, P. ovale, P. malariae or P. knowlesi
  • 2.1 Blood Stage infection
  • 2.1.1. Uncomplicated malaria caused by P. vivax
  • 2.1.1.1 In areas with chloroquine-sensitive P. vivax
  • Preferred regimen: Chloroquine total dose of 25 mg/kg PO. Chloroquine is given at an initial dose of 10 mg/kg, followed by 10 mg/kg on the second day and 5 mg/kg on the third day.
  • 2.1.1.2 In areas with chloroquine-resistant P. vivax
  • 2.1.2 Uncomplicated malaria caused by P. ovale, P. malariae or P. knowlesi malaria
  • Note: Resistance of P. ovale, P. malariae and P. knowlesi to antimalarial drugs is not well characterized, and infections caused by these three species are generally considered to be sensitive to chloroquine. In only one study, conducted in Indonesia, was resistance to chloroquine reported in P. malariae. The blood stages of P. ovale, P. malariae and P. knowlesi should therefore be treated with the standard regimen of ACT or Chloroquine, as for vivax malaria.
  • 2.1.3 Mixed malaria infections
  • Note: ACTs are effective against all malaria species and so are the treatment of choice for mixed infections.
  • 2.2 Liver stages (hypnozoites) of P. vivax and P. ovale
  • Note: To prevent relapse, treat P. vivax or P. ovale malaria in children and adults (except pregnant women, infants aged < 6 months, women breastfeeding infants < 6 months, women breastfeeding older infants unless they are known not to be G6PD deficient and people with G6PD deficiency) with a 14-day course of primaquine in all transmission settings. Strong recommendation, high-quality evidence In people with G6PD deficiency, consider preventing relapse by giving primaquine base at 0.75 mg base/kg bw once a week for 8 weeks, with close medical supervision for potential primaquine-induced adverse haematological effects.]
  • 2.2.1 Primaquine for preventive relapse
  • Preferred regimen: Primaquine 0.25–0.5 mg/kg/day PO qd for 14 days

  • Note: Do not use rectal artesunate in older children and adults.
  • 3.3 Pregancy
  • Note: Parenteral artesunate is the treatment of choice in all trimesters. Treatment must not be delayed.
  • 3.4 Treatment of severe P. Vivax infection
  • Note: parenteral artesunate, treatment can be completed with a full treatment course of oral ACT or chloroquine (in countries where chloroquine is the treatment of choice). A full course of radical treatment with primaquine should be given after recovery.
  • 3.5 Additional aspects of management in severe malaria
  • Fluid therapy: It is not possible to give general recommendations on fluid replacement; each patient must be assessed individually and fluid resuscitation based on the estimated deficit.
  • Blood Transfusion :In high-transmission settings, blood transfusion is generally recommended for children with a haemoglobin level of < 5 g/100 mL(haematocrit < 15%). In low-transmission settings, a threshold of 20% (haemoglobin,7 g/100 mL) is recommended.
  • Exchange blood transfusion: Exchange blood transfusion requires intensive nursing care and a relatively large volume of blood, and it carries significant risks. There is no consensus on the indications, benefits and dangers involved or on practical details such as the volume of blood that should be exchanged. It is, therefore, not possible to make any recommendation regarding the use of exchange blood transfusion.
