Updated: Aug 28, 2009
Gonorrhea is one of the most common and oldest known sexually transmitted diseases (STDs). It causes urethritis, cervicitis, epididymitis, pharyngitis, proctitis, and pelvic inflammatory disease (PID) and can spread throughout the body to cause both localized and disseminated disease. Most commonly, the term gonorrhea refers to urethritis and/or cervicitis in a sexually active person.
In the pediatric population, the importance of gonorrhea is 3-fold, as follows:
Neisseria gonorrhoeae is a gram-negative, intracellular diplococcus that grows best in the laboratory in an environment rich in carbon dioxide. Organisms are spread by sexual contact and can also be vertically transmitted during childbirth. N gonorrhoeae has a predilection for columnar mucosal cells. The physiologic ectopy of the squamocolumnar junction onto the ectocervix in the adolescent female is one factor that causes particular susceptibility to this infection.
Gonorrhea is the second most commonly reported infectious disease in the United States, after chlamydia. Actual incidence is difficult to determine due to high rates of asymptomatic carriage, as well as underreporting; however, in 2007, 355,991 cases were reported in the United States (a figure that seems to be stabilizing).1,2 The national average is 118.9 cases per 100,000 population, with considerable state-to-state variation.1 The rate is continuing to rise from 2004, when it was at its lowest level since 1941. The estimate of total cases is approximately 700,000 cases per year. In children who have been sexually abused, rates of recovery of gonorrhea range from 1-30%. In female adolescents who are sexually active, asymptomatic carriage of gonorrhea occurs in 1-5%.
Within the United States, carriage rates highly depend on the geographical area, the racial and ethnic group, and sexual preferences.
The South-Eastern States have the highest rates of infection; the rates in the midwest and northeast are much lower. Rates of infection range from about 285.7 cases per 100,000 population in Mississippi to 8.9 cases per 100,000 population in Maine. The Centers for Disease Control and Prevention (CDC) has a campaign (Healthy People 2010) that targets an incidence rate of 19 cases per 100,000 population. North Dakota, Maine, Vermont, Wyoming, New Hampshire, Montana, and Idaho are the only states currently exceeding that target, along with Puerto Rico. See Media file 1.
Disease rates are unknown for most developing countries. In much of Western Europe, rates approximate those in the United States.
When untreated, gonorrhea may progress locally to cause PID in females, epididymitis and orchitis in males, and sterility in both sexes. It can also spread to cause septic arthritis, perihepatitis (Fitz-Hugh-Curtis syndrome), and disseminated gonococcal infection (DGI). In newborns, vertical transmission can cause conjunctivitis, known as ophthalmia neonatorum, and blindness, if untreated. Oral sex with an infected partner can result in pharyngitis, and, similarly, anal infection can arise from anal sex or local spread from a vaginal source. PID often causes decreased fertility and can lead to tubo-ovarian abscess and, rarely, tubal perforation with peritonitis and death, especially if recurrent. Females with recurrent PID have high rates of ectopic pregnancy and infertility (approximately 8% after 1 episode, 20% after 2 episodes, and 40% after 3 or more episodes).
Frequency is increased among individuals of lower socioeconomic status and among minorities of any population because of decreased access to diagnosis and treatment. Lack of adequate care (ie, education, diagnosis, and treatment) leads to increased transmission rates.
The male-to-female ratio is approximately 1.2:1; females may be asymptomatic, whereas males are rarely asymptomatic. Men who have sex with men are much more likely to acquire and carry gonorrhea and also have far higher rates of antibiotic-resistant bacteria.
The highest incidence in the United States is among persons aged 15-24 years. This is likely due to the following:
The incubation period of gonorrhea is usually 2-7 days after exposure to an infected partner.
Risk factors for gonorrhea include the following:
| Appendicitis | Chlamydial Infections |
| Arthritis, Septic | Enuresis |
| Behcet Syndrome | Herpes Simplex Virus Infection |
| Candidiasis | Pharyngitis |
| Cervicitis | Trichomoniasis |
| Child Abuse & Neglect: Sexual Abuse | Urinary Tract Infection |
Bacterial Vaginosis
Ectopic Pregnancy
Epididymitis
Hepatitis
Orchitis
Pregnancy
Rat-bite Fever
Tubo-ovarian Abscess
Vaginitis
The main decision once a diagnosis of gonorrhea has been made, either definitively or presumptively, is whether to treat as an outpatient or to hospitalize.
In April 2007, the CDC updated treatment guidelines for gonococcal infection and associated conditions.3 Fluoroquinolone antibiotics are no longer recommended to treat gonorrhea in the United States and other parts of the world where resistance has become common, but they can be considered in areas where quinolone resistance has not yet emerged.
The recommendation was based on analysis of new data from the CDC's Gonococcal Isolate Surveillance Project (GISP).4 The data from GISP showed the proportion of gonorrhea cases in heterosexual men that were fluoroquinolone resistant reached 6.7%, an 11-fold increase from 0.6% in 2001. This limits treatment of gonorrhea to drugs in the cephalosporin class (eg, ceftriaxone 125 mg intramuscularly once as a single dose).
Fluoroquinolones may be an alternative treatment option for disseminated gonococcal infection if antimicrobial susceptibility can be documented. For more information, see the CDC's Antibiotic-Resistant Gonorrhea Web site, CDC Updated Gonococcal treatment recommendations (April 2007), or Medscape Medical News on CDC Issues - New Treatment Recommendations for Gonorrhea.
Medical therapy requires an antibiotic with efficacy against N gonorrhoeae. Until several years ago, the treatment of choice involved oral medication for as long as 10 days or an injection; however, patients tend to be poorly compliant with medications for various reasons, and the availability of newer medications has allowed in-office, single-dose, oral treatment to ensure compliance.
Many practitioners presumptively treat patients after obtaining specimens for diagnosis, based on history and examination, because of the risk of poor follow-up, complications, and continuing spread to other partners. In addition, because gonorrhea is often simultaneously diagnosed with chlamydia , many practitioners treat patients for both diseases when treating for either beyond the newborn period. Diagnosis and treatment of the patient's partner and any partners of the partner are important to prevent reinfection and complications.
Disseminated or complicated infections (eg, endocarditis, meningitis) require more prolonged inpatient therapy. For example, ceftriaxone 50 mg/kg IV bid for 7 days plus a macrolide such as azithromycin administered for simple disseminated infection (10-14 d for meningitis or 28 d for endocarditis). Fluoroquinolones are no longer recommended for gonorrhea because of increased resistance.
If cephalosporins are not an option for disseminated gonorrhea or PID, fluoroquinolones may be considered if the local data suggests antimicrobial susceptibility. For these cases, an infectious disease consult is essential. Children older than 8 years may omit the macrolide in cases of endocarditis.
Information from the CDC states that 2 g of oral azithromycin is effective against uncomplicated gonococcal infection but is expensive, causes GI irritation, and is not recommended for treatment of gonorrhea. Although 1 g of azithromycin theoretically meets alternative regimen criteria, it is not recommended because of concerns regarding the possible rapid emergence of antimicrobial resistance. N gonorrhoeae in the United States is not adequately susceptible to penicillins, tetracyclines, and macrolides (eg, erythromycin) for these antimicrobials to be recommended.3
DOC because of PO efficacy, single-dose treatment, and lower cost than parenteral medication. However, no longer manufactured in the United States and has limited availability.

Documented hypersensitivity; hepatic impairment; do not administer with pimozide
B - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
Bacterial or fungal overgrowth may result from prolonged antibiotic use; may increase hepatic enzymes and cholestatic jaundice; caution in patients with impaired hepatic function, prolonged QT intervals, or pneumonia; caution in hospitalized, geriatric, or debilitated patients; nausea, vomiting, and GI irritation may occur, particularly with large doses (ie, 2 g)
Inhibits protein synthesis and, thus, bacterial growth by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria.
100 mg PO bid for 7 d (for chlamydia, administer with cefixime or ceftriaxone)
Adolescents: 100 mg PO bid for 7 d (for chlamydia, administer with cefixime or ceftriaxone)
Bioavailability decreases with antacids containing aluminum, calcium, magnesium, iron, or bismuth subsalicylate; tetracyclines can increase hypoprothrombinemic effects of anticoagulants; tetracyclines can decrease effects of PO contraceptives, causing breakthrough bleeding and increased risk of pregnancy
Documented hypersensitivity; severe hepatic dysfunction
D - Fetal risk shown in humans; use only if benefits outweigh risk to fetus
Photosensitivity may occur with prolonged exposure to sunlight or tanning equipment; reduce dose in renal impairment; consider drug serum level determinations in prolonged therapy; tetracycline use during tooth development (last one half of pregnancy through age 8 y) can cause permanent discoloration of teeth; Fanconilike syndrome may occur with outdated tetracyclines
