Clinicians Often Fail to Test for HIV After Diagnosing AIDS-Defining Illnesses, U.S. Study Suggests (February 11, 2009)
Judy Chen, M.D., M.S.H.S., presents an analysis of 7,451 patients enrolled in private U.S. health insurance plans. The study found that clinicians frequently fail to even consider the possibility that a patient may be infected with HIV, even though the patient has been diagnosed with a potentially AIDS-defining event for which there often is virtually no other possible cause.

Early Expiration May Be Cause of Unusually High False-Positive Rates on OraQuick Rapid HIV Tests, Study Finds (February 11, 2009)
Experts have long been mystified by the sporadic clusters of false-positive results when using the OraQuick Advance Rapid HIV-1/2 Antibody Test. But Shelley Facente, M.P.H., and other researchers in California may have found the culprit: The tests appear to significantly lose their specificity as they near their expiration date.

High HIV Prevalence Found Among Male Partners of Thai Sex Workers (February 11, 2009)
Using a unique (and highly effective) means of recruitment, Neha Shah, M.D., M.P.H., colleagues discovered HIV prevalence rates of 20% or greater among male clients of female sex workers in Thailand. Among non-paying partners of those sex workers, Shah et al noted only slightly lower prevalence rates -- as well as inconsistent levels of condom use.

HIV on Par With Smoking, Diabetes as Risk Factor for Atherosclerosis, Large Study Finds (February 11, 2009)
Carl Grunfeld, M.D., Ph.D., and Colette Smith present new findings from a pair of massive studies that explore factors associated with cardiovascular risk in HIV-infected patients. Dr. Grunfeld's data suggest that HIV itself is a major risk factor for atherosclerosis -- a far greater risk, in fact, than any that may be posed by the use of antiretrovirals.

Many HIV-Infected Women Do Not Receive Cervical Cancer Screenings Nearly Often Enough, U.S. Study Suggests (February 11, 2009)
Despite the importance of annual cervical cancer screenings for HIV-infected women, 23% of a 2,400-woman nationwide sample reported no Pap smear within the past year, according to data presented by Alexandra Oster, M.D. Three factors were associated with an increased risk of missing a screening: age; CD4 count below 200; and receiving a pelvic exam from someone other than their HIV care provider.

Up to Half of HIV-Infected Patients on Effective HAART Still Ultimately Develop Neurocognitive Impairment, Study Finds (February 11, 2009)
Igor Grant, M.D., presents new data from the CHARTER study indicating that, although the prevalence of dementia is significantly down in the modern treatment era, 40 percent to 50 percent of HIV-infected patients on effective HAART will still eventually develop some form of neurological impairment -- and in most cases, the impairment will impact their day-to-day lives.

5% or More of Perinatally HIV-Infected Adolescents May Be Long-Term Nonprogressors, U.S. Study Suggests (February 10, 2009)
In what may be the first study of its kind, Rohan Hazra, M.D., offers data suggesting that a significant proportion of HIV-infected U.S. adolescents, all of whom were infected with HIV at birth, were able to remain off antiretroviral therapy for at least six months without experiencing any noticeable degree of disease progression.

Antidepressants Can Significantly Reduce Viral Load by Improving Adherence Among Homeless or Marginally Housed Patients, Study Says (February 10, 2009)
Antidepressant use had a small (.8 log) but statistically significant effect on viral load reduction among 418 homeless and marginally housed adults who had initiated HAART, found Alexander Tsai, M.D., Ph.D., et al. However, that benefit vanished after adjusting for adherence, suggesting that improved adherence was the reason behind the viral load reduction, not a biological effect of antidepressant use.

High-Dose Intravenous Immunoglobulin May Reduce Latent HIV Reservoir in Resting CD4+ Cells, Study Suggests (February 10, 2009)
A five-day course of high-dose intravenous immunoglobulin appears to somehow activate replication-competent HIV in the resting CD4+ cells of patients on HAART, ultimately leading to a reduction in those patients' latent HIV reservoirs, according to the results of a nine-patient study presented by Magnus Gisslén, M.D., Ph.D.

Maternal HAART Use During Breastfeeding Can Significantly Reduce Mother-to-Child Transmission Among Women With Low CD4+ Cell Counts, Study Finds (February 10, 2009)
Women with a CD4+ cell count below 250 can reduce their risk of vertical HIV transmission during breastfeeding by taking HAART, according to a study conducted in Malawi by Taha Taha, M.D., Ph.D., and colleagues. However, infant prophylaxis should be discontinued during breastfeeding if the mother is on HAART, Dr. Taha suggested, to avoid potentially dangerous drug levels in the infant.

Peripheral Neuropathy Still Common Among HIV-Infected Patients on HAART; Risk May Increase With Age (February 10, 2009)
A metastudy of ACTG trial participants finds peripheral neuropathy prevalence of greater than 20% among patients initiating HAART -- a proportion that increases as patients age, despite maintaining a CD4+ cell count above 350 and a viral load below 400, and despite declining use of didanosine and stavudine. Study presenter Scott Evans, Ph.D., also notes that neuropathy usually occurred without patients experiencing any pain whatsoever.

Ever Upward: "When to Start" Debate Turns to CD4+ Cell Count of 500 (February 9, 2009)
Dueling studies -- one presented by Mari Kitahata, M.D., the other by Jonathan Sterne, M.D. -- offer strikingly different views on the benefits of HAART initiation at a CD4+ threshold of 500. However, both appear to solidify the wisdom of starting therapy before CD4+ cell count drops below 350.
