Others STDs - Sexual Health Peer Resource Center

This fact sheet is taken directly from the NIAID fact sheet dated June 1998, available from their website at http://www.niaid.nih.gov/factsheets/stdother.htm. For the purposes of sex education at Stanford, these STDs are less common or not serious enough to merit a wider discussion, but are still included in order to give a more comprehensive view of sexual health. Although some of these diseases are less well-known in the United States than other STDs, they are still important -- some are especially significant for pregnant women. Many of these infections are of serious concern for people in other parts of the world, particularly in developing countries.

Chancroid

Chancroid (”shan-kroid”) is an important bacterial infection caused by Haemophilus ducreyi, which is spread by sexual contact. Periodic outbreaks of chancroid have occurred in the United States, the last one being in the late 1980s. These outbreaks are usually seen in minority populations in the inner cities, especially in the southern and eastern portion of the country. Globally, this disease is common in sub-Saharan Africa among men who have frequent contact with prostitutes.

The infection begins with the appearance of painful open sores on the genitals, sometimes accompanied by swollen, tender lymph nodes in the groin. These symptoms occur within a week after exposure. Symptoms in women are often less noticeable and may be limited to painful urination or defecation, painful intercourse, rectal bleeding, or vaginal discharge. Chancroid lesions may be difficult to distinguish from ulcers caused by genital herpes or syphilis. A physician must therefore diagnose the infection by excluding other diseases with similar symptoms. People with chancroid can be treated effectively with one of several antibiotics. Chancroid is one of the genital ulcer diseases that may be associated with an increased risk of transmission of the human immunodeficiency virus (HIV), the cause of AIDS.

Cytomegalovirus Infections

Cytomegalovirus (CMV) is a very common virus that infects approximately one-half of all young adults in the United States. It rarely causes serious consequences except in people with suppressed or impaired immune systems or in infants, whose immune systems are still developing. The virus, a member of the herpesvirus family, is found in saliva, urine, and other bodily fluids. Because it is often found in semen as well as in cervical secretions, the virus can be spread by sexual contact; it also can be easily spread by other forms of physical contact such as kissing. Day-care center staff for children under the age of 3 are at increased risk of CMV infection and should carefully wash their hands after changing diapers. Like other herpesvirus infections, CMV is incurable; people are infected with it for life. Although the virus usually remains in an inactive state, it can reactivate from time to time.

Symptoms: In healthy adults, CMV usually produces no symptoms of infection. Occasionally, however, mild symptoms of swollen lymph glands, fever, and fatigue may occur. These symptoms may be similar to those of infectious mononucleosis.

Diagnosis: The ELISA (enzyme-linked immunosorbent assay) test is commonly used to detect levels of antibodies (disease-fighting proteins of the immune system) in the blood. A number of other blood tests can suggest a diagnosis of CMV infection, but no blood test can reliably diagnose it. Although CMV can be isolated from urine or other body fluids, it may be excreted months or years after an infection; therefore, isolation of the virus from these fluids is not a reliable method of diagnosing recent infection.

Complications: Babies can be infected with CMV in the uterus if their mothers become infected with the virus or develop a recurrence of a previous infection during pregnancy. Although most babies infected with CMV before birth do not develop any symptoms, CMV is the leading cause of congenital infection in the United States. An estimated 6,000 babies each year develop life-threatening complications of congenital CMV infection at birth or suffer serious consequences later in life, including mental retardation, blindness, deafness, or epilepsy. Investigators supported by NIAID are currently studying how the virus interferes with normal fetal development and at which stages the fetus is most susceptible to infection. Congenital CMV is the most common cause of progressive deafness in children.

When CMV is acquired after birth, or if it reactivates, it can be life-threatening for persons with suppressed immune systems, such as those receiving chemotherapy or persons who have received immunosuppressant drugs for organ transplantation. Persons with HIV infection or AIDS may develop severe CMV infections, including CMV retinitis, an eye disease that can lead to blindness.

Treatment: NIAID scientists are testing new antiviral drugs that might be effective against CMV infections. The antiviral drugs foscarnet and ganciclovir have been approved for treating people with AIDS-associated CMV retinitis.

Prevention: There is no intervention to prevent CMV. Use of the male condom may reduce risk although virus in the saliva would be transmitted by kissing or oral intercourse. Some experts believe that primary or first-time exposure during pregnancy is a major cause of CMV infection in newborns. Infants infected before or just after birth are likely to be shedding CMV in saliva and urine, which can infect others. Hand washing and proper handling of diapers may reduce risk. Scientists are working to develop a vaccine and other methods to provide immunity to CMV and offer protection against severe disease.

Molluscum Contagiosum

This common viral infection most often affects young children, who pass it to each other through saliva. In adults, however, the virus is transmitted sexually, resulting in lesions on the genitals, lower abdomen, buttocks, or inner thighs. Most people with the infection do not have noticeable symptoms, although sometimes the lesions, which are painless wart-like bumps, usually donut shaped, may itch or become irritated. The lesions often heal without treatment, although physicians may sometimes scrape them off or treat them with chemical irritants.

Human T-Cell Lymphotropic Virus

The human T-cell lymphotropic viruses (retroviruses), HTLV-I and HTLV-II, are uncommon in the general U.S. population. They appear to be most prevalent among IV drug users and persons who have multiple sex partners, genital ulcers, or a history of syphilis. The virus can be transmitted by blood or intimate sexual contact, and can be passed from mother to child during pregnancy and through breast milk.

Most infected persons remain healthy carriers of the virus. In rare cases, however, HTLV-I can cause adult T-cell leukemia/lymphoma (ATL), a rare and aggressive cancer of the blood. Infected persons also may develop myelopathy, a neurologic disorder that affects the muscles in the legs. In addition, researchers think that HTLV-I plays a role in the development of B-cell chronic lymphocytic leukemia. HTLV-II can cause another rare cancer called hairy-cell leukemia. Because the chances of curing ATL rely on early detection, scientists are studying protein in the blood of HTLV-I-infected persons that may help predict who will develop the disease.

Blood donations are screened routinely for HTLV-I. Because lab tests cannot easily distinguish between HTLV-I and HTLV-II, experts believe many cases of HTLV-II are eliminated from the blood supply as well.
