What does GEORGE SIBERRY research?

George K Siberry focuses on the effects of antiretroviral medications, especially tenofovir, on both mothers and infants in the context of HIV treatment. He studies the safety of these drugs during pregnancy and breastfeeding, looking at how they affect kidney function, bone health, and overall health outcomes for infants. His research also explores the integration of HIV services into general healthcare settings for key populations who face barriers in accessing necessary care.

Key findings

  • In a study involving over 3,500 pregnant women on tenofovir, researchers found no significant kidney safety issues, indicating it's safe for use during pregnancy.
  • Infants exposed to tenofovir in late pregnancy showed a decrease in phosphate reabsorption of 0.58 units per day compared to 0.08 for unexposed babies and lower vitamin D levels (22 ng/mL vs. 26 ng/mL).
  • Routine HIV testing in South Africa increased diagnosis rates from 45.2% to 83.2% and treatment rates from 40.8% to 80.4%, demonstrating a cost-effective intervention.
  • Research showed that 4.9% of infants under 5 years receiving antiretroviral therapy died annually in 28 supported countries, highlighting higher mortality rates in very young children living with HIV.
  • Coverage for multi-month dispensing of antiretroviral therapy surged from 49% before COVID-19 to 72% during the pandemic, ensuring continuity of treatment for patients.

Kapogiannis BG, Nelson RM, Siberry GK, Lee S, Hazra R

Plain English
This study focused on improving prevention for HIV in at-risk adolescents by testing a method that allows them to consent to participate in research about HIV prevention treatments. Researchers found that using this mature minor consent approach was safe and effective, leading to new guidelines for prescribing HIV prevention drugs (PrEP) to teenagers. This matters because it helps reduce new HIV infections in vulnerable youth, especially since infection rates are rising in this age group. Who this helps: At-risk adolescents and their healthcare providers.

Cressey TR, Harrison L, Achalapong J, Kanjanavikai P, Patamasingh Na Ayudhaya O +14 more

Plain English
This study looked at how the drug tenofovir behaves in the bodies of women who are infected with hepatitis B but not HIV, during and after pregnancy. Researchers found that the amount of tenofovir in the women’s blood was about 20% lower while they were pregnant compared to after they gave birth, but this decrease did not lead to any cases of the virus being passed to the baby. This is important because it means that the current dosage of tenofovir does not need to change for pregnant women to effectively prevent the spread of hepatitis B to their children. Who this helps: This benefits women with hepatitis B who are pregnant and their newborns.

Impact of Human Immunodeficiency Virus Drug Resistance on Treatment of Human Immunodeficiency Virus Infection in Children in Low- and Middle-Income Countries.

2017

The Journal of infectious diseases

Siberry GK, Amzel A, Ramos A, Rivadeneira ED

Plain English
This study examined how drug resistance affects the treatment of HIV in children living in low- and middle-income countries. It found that children are more likely to experience treatment failure due to drug resistance, which is worsened by issues like less effective medications and difficulties in sticking to treatment. Improving available medications and support for taking them is crucial to help these children achieve better health outcomes. Who this helps: This helps children living with HIV and the healthcare providers treating them.
