HIV-infected infants respond poorly to childhood vaccinationDecember 05, 2007It is known that HIV-infected children who do not receive appropriate antiretroviral drugs experience immune depression, and may become susceptible to infectious diseases that would otherwise be prevented by childhood immunization. It is therefore important to find out to what extent HIV-infected children are able to generate adequate levels of antibodies following routine childhood immunizations. A paper published online this week in PLoS ONE describes the results of a cross-sectional study carried out amongst 18-36 month-old children born to HIV-infected mothers and living in Central Africa. The study suggested that immuno-suppressed HIV-infected children have a low persistence of antibodies to the vaccines of the Expanded Program on Immunization (EPI, WHO). The study was conducted in Cameroon and the Central African Republic by pediatricians, epidemiologists, bacteriologists and virologists, and coordinated by the Institut Pasteur (Paris, France) through its International Network, particularly the institutes based at the Pasteur Center in Yaoundé and at the Institut Pasteur in Bangui. The researchers found that antibody levels to measles vaccine was particularly low amongst children who were HIV infected, and that antibody levels to vaccine amongst HIV-uninfected children born to HIV-infected mothers were lower than expected. This latter finding raises the possibility that HIV exposure during pregnancy might influence the response to EPI vaccines in the first weeks of life. These results suggest that children living with HIV may need an adapted EPI vaccine schedule. Public Library of Science |

Weighing costs, benefits of HIV treatments Prevention versus treatment? Cost versus efficacy? So go two of the dilemmas looming over Dartmouth's Paul E. Palumbo, M.D., and his fellow researchers in the race to fight HIV and other infectious diseases in the developing world - especially among women and their young children. Adherence to antiretroviral therapy high in children in low income countries Researchers from the Indiana University School of Medicine, the Regenstrief Institute and Moi University School of Medicine are the first to report that adherence to antiretroviral therapy (ART) to fight human immunodeficiency virus (HIV) in children who live in low income countries is as high as or higher than adherence by children living in high income countries. Early cessation of breastfeeding by HIV+ women in poor countries and child survival A new study by researchers from Columbia University's Mailman School of Public Health addresses one of the most challenging issues in infant health and preventing mother-to-child HIV transmission in poor countries. Pneumococcal conjugate vaccines can improve the lives of HIV-infected children An international team of experts has published the first comprehensive review of evidence on pneumococcal conjugate vaccination (PCV) for children with HIV infection. Studies affirm need for influenza and measles vaccinations in HIV-infected patients Two new studies emphasize the importance of delivering measles and influenza vaccines to HIV-infected individuals. Both studies are published in the August 1 issue of The Journal of Infectious Diseases, now available online. Measles Vaccinations Need to be Repeated to Protect HIV-Infected Children HIV-infected children may require repeat measles vaccination for protection, according to new research from the Johns Hopkins Bloomberg School of Public Health and other institutions. Combination anti-retroviral therapies associated with reduced infections in HIV-infected children Since the introduction of highly active antiretroviral therapies, there has been a substantial reduction of opportunistic infections and other infections in HIV-infected children, such as pneumonia and tuberculosis. Zinc Supplements Safe for HIV-Infected Children Zinc-deficient children living in communities where they do not receive adequate amounts of zinc from their diet should be given supplements, even if they are HIV-infected. World Experts Unite in Urgent Effort to Fight Deadly Disease * Up to One Million Child Deaths are Preventable * * New Evidence Shows HIV-Infected Children & Infants are Particularly Vulnerable * Leaders in the fight against disease today emphasized the importance of preventing unnecessary child deaths from Streptococcus pneumoniae - a disease currently responsible for killing between 800,000 and one million children every year, mostly in developing countries. The reaffirmed consensus on the need for new interventions to fight the disease came on the eve of the fourth International Symposium on Pneumococci and Pneumococcal Diseases (ISPPD-4) in Helsinki.
