Mother-to-child HIV transmission rate falling, but more can be done

26.07.2010
Transmission of HIV to children before or at birth has dropped dramatically around the country in the last decade since the advent of powerful new therapies. That certainly is true for Florida, where each year, fewer than 10 babies are born with the disease despite the fact that more than 600 HIV-positive women each year, on average, give birth.

Still, more can be done to even further reduce the number of babies born with the disease, say pediatric HIV experts at the University of Florida who this week presented their work during the 18th International AIDS conference in Vienna, Austria.

"This is one of those diseases for which we learned how to prevent transmission. We need to make full use of this method and our energies need to be focused on the effort," said lead researcher Dr. Mobeen Rathore, a professor and chief of pediatric infectious diseases and immunology at the University of Florida College of Medicine-Jacksonville, and director of the UF Center for HIV/AIDS Research, Education and Service.

Around the United States, the decreasing number of pediatric infections is a direct result of the advent of powerful anti-HIV therapies in the mid-1990s and the establishment of protocols by the Centers for Disease Control and Prevention to treat pregnant women who are infected, and their babies.

Increased HIV-testing outreach and education efforts have also paid off. And CDC guidelines for "opt-out" HIV-testing for pregnant women mean testing is a routine part of their care, and women would have to specifically decline it. Rapid testing during labor and delivery gives one last chance to administer therapies that can prevent transmission.

In Florida, the Targeted Outreach for Pregnant Women Act of 1998 was enacted to help improve prenatal care and reduce the number of babies with HIV or prenatal drug exposure.

After New York, Florida has the second highest number of babies born to HIV-positive women. The state began monitoring the number of HIV-exposed babies in 2006. Up to 2008, a total of 2,374 cases of pediatric HIV/AIDS have been reported in Florida. So far this year, just one case has been reported.

"The reduction of mother-to-child HIV transmission is one of the biggest success stories of the HIV epidemic," said Thomas Liberti, chief of the bureau of HIV/AIDS in the Florida Department of Health. "The question is, 'How low can we go?'"

The UF researchers teamed with colleagues in the Florida Department of Health Perinatal Prevention Division to review pediatric HIV data for the period from 2002-09, and found 102 cases.

Despite the many effective measures in place to help prevent HIV-transmission to babies, there are missed opportunities, the researchers found.

Mothers of half of the infected babies tested positive for HIV before becoming pregnant. But some refused or neglected to take the medications that could have kept their babies HIV-free. Some had no prenatal care, and so did not receive available treatments.

Some women were HIV-negative at the start of their pregnancy, but became infected afterward. Others were diagnosed with HIV only after the birth of their babies. Repeat testing during pregnancy and rapid testing during labor and delivery would have alerted health care providers.

The study shows that for some women, the issue might not be a lack of availability of medical services. Mental illness, intravenous drug use and incarceration and other risk factors associated with increased risk of HIV infection affected about one-third of the women who delivered infected babies. Mental health and substance abuse issues often prevent women from taking advantage of medical care or adhering to a treatment regimen prescribed by their physicians.

Finding creative ways to address issues such as the shortage of mental health-care providers will help women and their babies get needed care, the researchers said.

The health department has already begun discussions with the Centers for Disease Control and Prevention to discuss steps that can be taken to further reduce mother to child HIV transmission.

"Many of our patients have mental health and other life issues, so if we do not address them, the treatment protocol will not be effective," Rathore said. "This is an intervention that has the opportunity to work better."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
