Young Africans Suffering Advanced HIV Disease From Delayed Diagnosis

Science Daily - A new study suggests the effects of long-standing,
undiagnosed HIV infection are hanging over a generation of adolescents in
Zimbabwe, causing organ damage, chronic ill health, stunted growth, and
other problems. The research demonstrates the need to reduce barriers to
early testing and admission to care for these adolescents. It appears in the
March 15 issue of Clinical Infectious Diseases, currently available online.

"We suspect that there is a substantial and growing burden of long-standing
HIV infection and AIDS in this age group," said lead author Rashida Ferrand,
MBBS, MRCP, DTMH, "especially in countries where HIV prevalence in pregnant
women has been high for over ten years--giving time for survivors of
mother-to-child transmission to grow up." She and her colleagues from London
and Zimbabwe have recently completed a study of 32 adolescents from the
Connaught Clinic in Harare, Zimbabwe.

Because of the difficulties and expense of obtaining HIV testing and care,
the average delay between the first serious illness to HIV diagnosis was 3.5
years, despite the fact that 75 percent of the parents or guardians
suspected HIV infection. By the time they sought care, many of the patients
had long histories of the types of ill health that suggest HIV infection,
including chronic skin, respiratory, and gastrointestinal symptoms. In
addition, many of the patients' health care providers must have considered
the possibility of an HIV diagnosis, as more than 40 percent of the
participants had taken cotrimoxazole, an antibiotic which the World Health
Organization recommends be given to HIV-infected children to prevent
pneumocystis pneumonia and other infections.

"A delayed diagnosis means that patients present late in the course of HIV
infection," said Dr. Ferrand, "by which time they may already have
significant and irreversible damage to vital organs such as the heart and
lungs, plus an increased risk of serious opportunistic infections with high
mortality." These infections are preventable with antiretroviral therapy
(ART) and cotrimoxazole.

Earlier diagnosis of HIV infection is paramount, as there is a higher risk
of death and disease progression in patients who delay starting treatment
until they have advanced disease. Earlier treatment is also crucial.
Previous studies show treatment is less effective if started in patients who
have advanced disease. The opportunity for "catch-up" growth on ART may be
lost if it is delayed until late adolescence.
"What we are looking at here are the consequences of not having programs to
prevent maternal-to-child transmission of HIV in the 1990s," said Dr.
Ferrand. "We need to deal with these children who have already suffered
terribly from the indirect effects of HIV: orphanhood, impoverishment, and
the psychological trauma of prolonged illness in parents and siblings. More
research into the scope of the problem of late-childhood HIV/AIDS and the
problems faced so stoically by these vulnerable and ignored group of
patients -- medical, socio-economic, and psychosocial -- will help in the
development of policy and practice. And we need to strengthen programs to
prevent maternal-to-child transmission so that we can prevent this problem
in the future."
