Treatment
Medical Care
Patients presenting with suspected or diagnosed chancroid should undergo complete evaluation for other possible concomitant STDs and receive appropriate antimicrobial therapy for the eradication of H ducreyi.
- The CDC recommends antibiotic therapy from 1 of 4 equally efficacious agents, as follows8 :
- Azithromycin
- Ceftriaxone
- Erythromycin base
- Ciprofloxacin
- Evaluate patients for syphilis, herpes simplex virus (HSV), and HIV.
- Drain fluctuant lymph nodes larger than 5 cm in diameter by either needle aspiration or incision and drainage.
Activity
Patients should abstain from unprotected sexual intercourse while undergoing treatment.
Medication
The goal of therapy is the eradication of the organism.
Antibiotics
Therapy must be comprehensive and cover all likely pathogens in the context of this clinical setting.
Azithromycin (Zithromax)
Treats mild-to-moderate microbial infections.
Adult
1 g PO single dose
Pediatric
<6 months: Not established
>6 months: 10 mg/kg PO single dose; not to exceed 500 mg/d
May increase toxicity of theophylline, warfarin, and digoxin; effects are reduced with coadministration of aluminum and/or magnesium antacids; nephrotoxicity and neurotoxicity may occur when coadministered with cyclosporine
Documented hypersensitivity; hepatic impairment; concomitant administration with pimozide
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Site reactions can occur with IV route; bacterial or fungal overgrowth may result with prolonged antibiotic use; may increase hepatic enzymes and cholestatic jaundice; caution in patients with impaired hepatic function, prolonged QT intervals, or pneumonia; caution in patients who are hospitalized, elderly, or debilitated
Ceftriaxone (Rocephin)
Third-generation cephalosporin with broad-spectrum gram-negative activity. Lower efficacy against gram-positive organisms. Higher efficacy against resistant organisms. Arrests bacterial growth by binding to 1 or more penicillin-binding proteins.
Adult
250 mg IM single dose
Pediatric
>7 days: 25-50 mg/kg/d IV/IM; not to exceed 125 mg/d
Infants and children: 50-75 mg/kg/d IV/IM divided q12h; not to exceed 2 g/d
Probenecid may increase levels; coadministration with ethacrynic acid, furosemide, and aminoglycosides may increase nephrotoxicity
Documented hypersensitivity
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Adjust dose in renal impairment; caution in breastfeeding women and allergy to penicillin
Erythromycin (E.E.S., E-Mycin, Eryc, Ery-Tab, Erythrocin)
Inhibits bacterial growth, possibly by blocking dissociation of peptidyl tRNA from ribosomes, causing RNA-dependent protein synthesis to arrest. For treatment of staphylococcal and streptococcal infections.
Adult
500 mg PO qid for 7 d
Pediatric
30-50 mg/kg/d (15-25 mg/lb/d) PO divided q6-8h; double dose for severe infection
Coadministration may increase toxicity of theophylline, digoxin, carbamazepine, and cyclosporine; may potentiate anticoagulant effects of warfarin; coadministration with lovastatin and simvastatin increases risk of rhabdomyolysis
Documented hypersensitivity; hepatic impairment
Pregnancy
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Precautions
Caution in liver disease; estolate formulation may cause cholestatic jaundice; GI adverse effects are common (administer pc); discontinue use if nausea, vomiting, malaise, abdominal colic, or fever occur
Ciprofloxacin (Cipro)
Fluoroquinolone with activity against pseudomonads, streptococci, MRSA, Staphylococcus epidermidis, and most gram-negative organisms, but no activity against anaerobes. Inhibits bacterial DNA synthesis and, consequently, growth.
Adult
500 mg PO bid for 3 d
Pediatric
<18 years: Not recommended
>18 years: Administer as in adults
Antacids, iron salts, and zinc salts may reduce serum levels; administer antacids 2-4 h before or after taking fluoroquinolones; cimetidine may interfere with metabolism of fluoroquinolones; ciprofloxacin reduces therapeutic effects of phenytoin; probenecid may increase ciprofloxacin serum concentrations; may increase toxicity of theophylline, caffeine, cyclosporine, and digoxin (monitor digoxin levels); may increase effects of anticoagulants (monitor PT)
Documented hypersensitivity
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
In prolonged therapy, perform periodic evaluations of organ system functions (eg, renal, hepatic, hematopoietic); adjust dose in renal function impairment; superinfections may occur with prolonged or repeated antibiotic therapy
