Gonorrhea (slang term "the clap") is among the most common curable sexually transmitted diseases in the world and is caused by the Gram-negative bacterium called Neisseria gonorrhoeae.

Infection with gonorrhea increases the risk of becoming infected with HIV (human immunodeficiency virus, the virus that causes AIDS). This is likely due to weakening of the mucosal surface secondary to the gonorrhea infection. Note, however, that this effect is by no means limited to gonorrhea and there is increased risk of HIV transmission with co-infection of most sexually transmitted diseases (STDs).

The first place this bacterium infects is usually the columnar epithelium of the urethra and endocervix. Non-genital sites in which it thrives are the rectum, the oropharynx and the conjunctivae (eyes). The vulva and vagina in women are usually spared because they are lined by stratified epithelial cells, so, in women, the cervix is the usual first site of infection.

Gonorrhea spreads during sexual intercourse. Infected women also can pass gonorrhea to their newborn infants during delivery, causing eye infections in their babies. This complication is now rare because newborn babies receive eye medicine to prevent infection. When the infection occurs in the genital tract, mouth, or rectum of a child, it is most commonly due to sexual abuse.





In 2000, 358,995 cases of gonorrhea were reported to the U.S. Centers for Disease Control and Prevention (CDC). In the United States, approximately 75 percent of all reported cases of gonorrhea are found in younger persons aged 15 to 29 years. The highest rates of infection are usually found in 15- to 19-year old women and 20- to 24-year-old men. Health economists estimate that the annual cost of gonorrhea and its complications is close to $1.1 billion.

The disease can spread into the uterus and Fallopian tubes, resulting in pelvic inflammatory disease (PID). PID affects more than 1 million women in the United States every year and can cause infertility in as many as 10 percent of infected women and tubal (ectopic) pregnancy.





The incubation period varies from 2 to 14 days with most symptoms occurring between days 2 and 5 after being infected from an infected partner. A small number of people may be asymptomatic for several months.

Men
In male patients dysuria accompanied by thick, copious, purulent (condensed milk-like) urethral discharge is the most common presentation. Examination show a reddened external urethral meatus. This urethral inflammation accompanied by discharge, and sometimes the discharge itself, are occasionally called "gleet." Without effective treatment, ascending infection could extend to the epididymis, testes or prostate causing symptoms such as scrotal pain or swelling.

Men and women with rectal gonorrhea may present with anal discharge, perianal pruritus, tenesmus and rectal bleeding. Proctoscopy shows inflamed mucous membrane with little mucous.

Women
About 50% of women with gonorrhoea are asymptomatic. The patient may complain of a vaginal discharge, dysuria, intermenstrual bleeding or postcoital bleeding. The cervix may appear anywhere from normal to the extreme of marked cervicitis with a mucopurulent exudate. Involvement of the urethra causes little dysuria, purulent secretion and frequency. The combination of urethritis and cervicitis on examination is very suggestive of the diagnosis as both sites are infected in most patients.

More advanced symptoms, which may indicate development of PID, include cramps and pain, bleeding between menstrual periods, vomiting, or fever.

Gonococcal conjunctivitis
Infection of the eyes with gonorrhoea can result from rubbing of the eyes with contaminated fingers in both sexes, and presents with pain and a purulent yellow discharge. The conjunctivae are inflamed with chemosis, keratopathy and corneal ulceration leading to blindness in severe cases.

Gonococcal ophthalmia develop within 7 days of birth of a baby to an affected mother and is usually bilateral with intense conjunctivitis, copious purulent secretion and lid edema. Without proper urgent treatment, ulceration of the cornea leading to scarring will seriously affect vision.





In men, epididymitis, prostatitis and urethral stricture can result from untreated gonorrhoea.

In women, Bartholinitis and abscess formation (causing trouble walking), pelvic inflammatory disease (PID) and Fitz-Hugh-Curtis syndrome can occur.

The most common result of untreated gonorrhea is PID, a serious infection of the female reproductive tract. PID causes scarring of the fallopian tubes which leads to increased risks of causing an ectopic pregnancy as a fertilized egg may not be able to pass through the narrowed, scarred fallopian tube. Ectopic pregnancies are serious conditions which are potentially life-threatening to the mother.

In both sexes, disseminated gonococcal infection (DGI) can occur, leading to multiple distant sites of infection which can include the brain, heart and joints.





Doctors or other health care workers usually use three laboratory techniques to diagnose gonorrhea: staining samples directly for the bacterium, detection of bacterial genes or DNA in urine, and growing the bacteria in laboratory cultures. Many doctors prefer to use more than one test to increase the chance of an accurate diagnosis.

The staining test involves placing a smear of the discharge from the penis or the cervix on a slide and staining the smear with a dye. Then the doctor uses a microscope to look for bacteria on the slide. You usually can get the test results while in the office or clinic. This test is quite accurate for men but is not good in women. Only one in two women with gonorrhea have a positive stain.

More often, doctors use urine or cervical swabs for a new test that detects the genes of the bacteria. These tests are as accurate or more so than culturing the bacteria, and many doctors use them.

The culture test involves placing a sample of the discharge onto a culture plate and incubating it up to 2 days to allow the bacteria to grow. The sensitivity of this test depends on the site from which the sample is taken. Cultures of cervical samples detect infection approximately 90 percent of the time. The doctor also can take a culture to detect gonorrhea in the throat. Culture allows testing for drug-resistant bacteria.

The mainstay of treatment is the appropriate use of antibiotics. An increase in antibiotic resistance has led to the decline in use of penicillin for treating gonorrhoea. Nowadays, a third generation cephalosporin such as ceftriaxone is recommended for treating gonorrhoea.

Doctors usually prescribe a single dose of one of the following antibiotics to treat gonorrhea:

  • Cefixime

  • Ceftriaxone

  • Ciprofloxacin

  • Ofloxacin

  • Levofloxacin

  • Tequin


As coinfection with chlamydia is common, doctors often prescribe a combination of antibiotics, such as ceftriaxone and doxycycline or azithromycin, which will treat both diseases.

Follow up treatment is needed to ensure the organism has been eradicated. Sexual contacts should also be screened and treated if necessary.





Pregnant mothers infected with gonorrhea, can transmit the disease to their babies during childbirth.

Gonococcal conjunctivitis is a major preventable cause of blindness in newborns so if there is a known risk of transmitting gonorrhoea, prophylactic silver nitrate or other medications may be applied to the baby's eyes immediately after birth.

Because of the risks of vertical transmission, doctors recommend that pregnant women have at least one test for gonorrhea during pregnancy.






As gonorrhea is a STD, proper use of barrier contraceptives such as the latex condoms will significantly reduce the risk of getting gonorrhea and its complications.





Gonorrhea is also commonly known by the slang term "the clap" - suggested etymology from the Old French word "clapier", meaning "brothel". (Another suggested source for the term is from the notorious 18th century brothel keeper known as "Mother Clap", though perhaps her name itself was derived from the slang term). It could also refer to the painful sting in the male urethra, which feels like the sting of a clap when infected with the disease.
Yet another suggested source for this nickname is "the clap" refers to a treatment that used to clear the blockage in the urethra from gonorrhea pus, where the penis would be clapped on both sides simultaneously. This gonorrhea treatment is rarely used today, however the nomenclature remains. (Ref. http://std-gov.org/stds/gonorrhea.htm STD Guide: Gonorrhea)
