Benefits of Early Initiation of Treatment in HIV-infected Individuals

 
During the “Reach for the Top: Can We Perfect Current ART?” abstract session held at the 7th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2013), researchers presented evidence showing that initiating antiretroviral therapy (ART) in chronically HIV-1 infected patients before their CD4+ count falls below 500/mm3 leads to better outcomes.
 
In their study “In chronically HIV-1-infected patients long-term antiretroviral therapy initiated above 500 CD4/mm3 achieves better HIV-1 reservoirs' depletion and T cell count restoration,” Laurent Hocqueloux, MD, and colleagues looked at a cohort of chronically infected patients patients being treated with efficient cART who had a normal CD4+ T cell count  (≥900/mm3), a normal CD4/CD8 ratio (>1), and a low HIV-DNA level (<2.3 Logcp/106 PBMC) “according to their nadir CD4+ T cell count prior to starting ART.
 
Patients were stratified according to CD4+ nadir: >500, 350-500, 200-350 and < 200 cells/mm3. They measured total HIV-DNA in PBMC at least once a year before (when possible) and during treatment. They also measured T-cell count (CD4+, CD8+) and PVL every 3-4 months.

A group of international researchers led by Luosheng Li, MD, of the Rolf Luft Research Center for Diabetes and Endocrinology at the Karolinska Institutet, Karolinska University Hospital in Stockholm, Sweden, recently demonstrated that age-dependent decline in insulin secretion (and thus glucose homeostasis) from the beta cell in experimental mice models is associated with subtle changes in Ca2+ dynamics.
For patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), the right treatment can make a world of difference in the management of their condition. A recent study looked at how effective inhaled budesonide and systemic methylprednisolone can be for those patients.
