A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem

OBJECTIVE: We studied trends in initial post infection CD4 cell counts and viral load values in patients diagnosed at estimated time of primary infection between 1997 and 2005 in France.

POPULATION AND METHODS: We selected from the French Hospital Database on HIV infection white patients with documented dates of sexually transmitted HIV-1 infection who had a first CD4 cell count (n = 1441) or viral load assay (n = 1402) within 12 months after infection and before any antiretroviral therapy. Chronological trends in initial CD4 cell counts and viral load values were studied by using linear regression analysis.

RESULTS: The initial CD4 cell count declined by an average of 5.76 cells per cubic millimeter per year [95% confidence interval (CI): -11.28 to -0.24 cells/mm3 per year] and compared with 1997 initial viral load increased significantly by a mean of 0.376 log10 copies per milliliter (95% CI: 0.044 to 0.707 log10 copies/mL) in 1999, 0.548 log10 copies per milliliter (95% CI: 0.288 to 0.808 log10 copies/mL) in 2000-2002, and 0.525 log10 copies per milliliter (95% CI: 0.267 to 0.7783 log10 copies/mL) in 2003-2005.

CONCLUSION: We think that lower CD4 cell counts and higher viral loads at a given time post infection suggest a more rapid progression of the disease and therefore an increased HIV pathogenicity.
