Zidovudine (Retrovir) should be included in the antiretroviral regimen of pregnant patients with human immunodeficiency disease regardless of their viral load or CD4+ cell count.


The most recent recommendations from the Centers for Disease Control and Prevention (CDC)18 regarding optimal antiretroviral therapy are to treat pregnant women infected with HIV the same as adults infected with HIV who are not pregnant using clinical, virologic and immunologic status to guide treatment decisions. One difference for pregnant women is to include zidovudine in every treatment regimen given the extensive data demonstrating its benefits.
FDA Pregnancy Categories of Antiretroviral Drugs

Category A
None

Category B
Didanosine (Videx)
Nelfinavir (Viracept)
Ritonavir (Norvir)
Saquinavir (Fortovase)



Category C
Abacavir (Ziagen)
Amprenavir (Agenerase)
Delavirdine (Rescriptor)
Efavirenz (Sustiva)
Indinavir (Crixivan)
Lamivudine (Epivir)
Nevirapine (Viramune)
Stavudine (Zerit)
Zalcitabine (HIVID)
Zidovudine (Retrovir)



Approved for patients less than 1 year of age
Abacavir
Didanosine
Lamivudine
Nevirapine
Stavudine
Zidovudine

Interventions to Decrease the Rate of Vertical Transmission of HIV

Zidovudine therapy
Highly active antiretroviral therapy
Suppressing maternal viral load to undetectable levels
Elective cesarean section at 38 weeks
Prevention of opportunistic infections
Prevention of preterm delivery
Reducing time between rupture of membranes and delivery to less than four hours
Minimizing fetal exposure to maternal blood

Summary of Modifications to Care for Obstetric Patients with HIV Infection

First trimester
Screen pregnant patients for HIV infection.
Measure viral load and CD4+ lymphocyte count.

Initiate highly active antiretroviral regimen.
If antiretroviral naïve, may delay therapy until second trimester.
Include zidovudine (Retrovir) in antiretroviral regimen.

If CD4+ cell count is less than 200 per mm3 (200 X 106 per L), initiate PCP prophylaxis.
Update influenza and pneumococcal vaccinations if appropriate.
Obtain necessary social support for patient.

Second trimester
Measure viral load and CD4+ cell count.
Modify antiretroviral regimen based on viral load.
If CD4+ lymphocyte count is less than 50, initiate MAC prophylaxis.

Check PPD status.
If PPD is positive, administer isoniazid (INH) and pyridoxine (vitamin B6) prophylaxis.



Third trimester
Measure viral load and CD4+ lymphocyte count.
Modify antiretroviral regimen based on viral load.

Discuss risks and benefits of elective cesarean section.
If elective cesarean section is planned, perform at 38 weeks of gestation.
If vaginal delivery is planned, minimize fetal exposure to maternal blood during delivery.
If vaginal delivery is planned, deliver less then four hours after rupture of membranes.

Infant
Initiate zidovudine therapy.


* The key to preventing MTCT of HIV in the United States is universal HIV testing of pregnant women.
* The AAP recommends "opt out" consent or "right of refusal." After being notified that testing will be performed, all pregnant women in the United States should undergo routine HIV testing unless they decline this testing.
* To further decrease the rate of perinatal HIV transmission, repeated testing in the third trimester may be helpful, particularly in high-risk groups.
* Rapid HIV testing at labor and delivery may also be helpful, using new, rapid testing methods that can identify HIV-infected women or HIV-exposed infants in 20 to 60 minutes.
* Women in labor with undocumented HIV infection status during the current pregnancy should undergo immediate rapid HIV antibody testing with opt-out consent.
* Immunofluorescent antibody or Western blot assay should be used to confirm positive HIV antibody screening test results, but prophylaxis should not be delayed while awaiting definitive test results.
* Preventing MTCT of HIV is most effective when antiretroviral drugs are given to the mother during her pregnancy, continued through delivery, and then given to the newborn infant.
* Antiretroviral drugs are effective in reducing the risk for MTCT of HIV even when prophylaxis is started for the infant soon after birth.
* When rapid HIV antibody test result is positive in a pregnant woman, antiretroviral prophylaxis should be promptly given to the mother and newborn without waiting for results of confirmatory HIV testing.
* If the confirmatory test result is negative, prophylaxis should be discontinued.
* When the mother's HIV serostatus is unknown, rapid HIV antibody testing should be performed on the mother or on the newborn, and results should be reported to the healthcare professional within 12 hours after the infant's birth.
* If the rapid HIV antibody test result is positive, antiretroviral prophylaxis should be started as soon as possible and no later than 12 hours after delivery.
* Pending completion of confirmatory HIV testing, the mother should be counseled not to breast-feed, but she should be assisted with immediate initiation of hand and pump expression to stimulate milk production.
* If the confirmatory test result is negative, prophylaxis should be stopped and breast-feeding may begin.
* If the confirmatory test result is positive, the mother should not breast-feed, and the infant should receive antiretroviral prophylaxis for 6 weeks after birth.

Pearls for Practice

* The key to preventing MTCT of HIV in the United States is universal HIV testing of pregnant women, using "opt out" consent or "right of refusal." To further decrease the rate of perinatal HIV transmission, repeated testing in the third trimester may be helpful, particularly in high-risk groups. New methods of rapid HIV testing at labor and delivery may identify HIV-infected women or HIV-exposed infants in 20 to 60 minutes.

CDC Updates 2001 Guideline on HIV Prophylaxis Following Occupational Exposure


* Exposures to HIV-infected blood, cerebrospinal, synovial, pleural, peritoneal, pericardial, amniotic, vaginal fluids, and semen are all considered potentially infectious for HCP. Larger quantities of blood pose a higher risk for infection also. Nasal or fecal secretions, saliva, sputum, sweat, tears, urine, and vomitus are not considered potentially infectious unless they are visibly bloody.
* HIV PEP should begin early in association with infectious disease consultation, and reevaluation should occur within 72 hours. Two-drug regimens are recommended for low-risk and three- or four-drug regimens for higher-risk exposures.

Treatment Protocols for Postexposure Prophylaxis After Sexual Assault
Treatment regimen (28 days)
Zidovudine, 300 mg twice daily or 200 mg three times daily
and
Lamivudine, 150 mg twice daily
Alternative regimen (28 days)
Didanosine, 200 mg twice daily
and
Stavudine, 40 mg twice daily
Consider adding*
Nelfinavir, 750 mg three times daily
or
Indinavir, 800 mg three times daily
Testing of victim
HIV antibody test (repeat at 6 weeks, 3 months and 6 months)
Hepatitis B virus antibody test
Gonorrhea, Chlamydia and syphilis tests
Wet mount for trichomonas
Pregnancy test (if appropriate)
Hepatic enzyme levels (repeat as clinically indicated)
Complete blood count (repeat as clinically indicated)
HIV = human immunodeficiency virus.
*--A protease inhibitor should be added when the assailant is known to be infected with HIV resistant to reverse transcriptase inhibitors.
