Testing times: detecting HIV in resource-limited settings

29.11.2007
Integrating HIV testing programmes into primary medical care can help achieve early diagnosis of HIV infection, even in relatively poor areas, research published in the online open access journal AIDS Research and Therapy has shown.

Researchers from Harvard Medical School and the non-governmental organisation Partners In Health (PIH, www.pih.org), both based in Boston, USA set out to see if HIV diagnosis was delayed because doctors missed opportunities to test people who were at risk of HIV during clinic visits.

The team works with the Haitian Ministry of Health to improve patients' access to primary care in central Haiti. This includes "provider-initiated HIV testing" (offering patients HIV tests when they visit primary care clinics) and the provision of free HIV treatment if required. The researchers then looked back at records from a single primary care clinic to examine the 'missed opportunities' and delays in diagnosing patients with HIV.

The researchers found few missed opportunities for diagnosis in the clinic - 85% of the first 112 patients found to have HIV were diagnosed on their first visit to the doctor. Patients with HIV who were not diagnosed on their first visit had to wait a median of just 62 days until diagnosis.

In the developing world, much HIV testing is done through maternity clinics or special HIV clinics that perform voluntary counselling and testing (i.e. on request of the individuals themselves) but that often do not provide other medical services or comprehensive HIV treatment. The authors suggest that provider-initiated testing at primary care clinics can be an effective way to identify patients with HIV infection.

They write: "HIV prevention and treatment programs will not achieve success without addressing the urgent need for individuals to be aware of their HIV status in a timely manner and provider-initiated testing can be a successful strategy to address this concern."

About AIDS Research and Therapy
AIDS Research and Therapy is an open access, online journal that publishes peer-reviewed research articles from scientists working to prevent the spread of AIDS. AIDS Research and Therapy aims to publish basic science as well as clinically important research articles that impact on abating the spread of AIDS. This multidisciplinary journal aims to keep scientists and clinicians abreast of the latest research on HIV-1. The ultimate goal of the journal's focus is to lead bench research to bedside practice to combat AIDS. AIDS is spreading at alarming rates in several African and Asian countries. Thus, any development that occurs in combating AIDS should be disseminated as rapidly as possible through the world. Although there are several AIDS-related journals in print, none of them are openly accessible to the world through the Internet. AIDS Research and Therapy will provide an open access journal specifically devoted to HIV-1 and AIDS research.
About BioMed Central
BioMed Central (http://www.biomedcentral.com) is a UK-based independent online publishing house committed to providing open access to peer-reviewed biological and medical research. This commitment is based on the view that immediate free access to research and the ability to freely archive and reuse published information is essential to the rapid and efficient communication of science.

BioMed Central currently publishes over 180 journals across biology and medicine. In addition to open-access original research, BioMed Central also publishes reviews, commentaries and other non-original-research content. Depending on the policies of the individual journal, this content may be open access or provided only to subscribers.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
