  57. ncbi Highly active antiretroviral therapy with or without mycophenolate mofetil in treatment-naive HIV-1 patients
    Sanjay U C Sankatsing
    Department of Internal Medicine, Division of Infectious Diseases, Tropical Medicine and AIDS, University of Amsterdam, The Netherlands
    AIDS 18:1925-31. 2004
    ..CONCLUSION: The addition of MMF to a triple class antiretroviral regimen in treatment-naive patients does not significantly increase the plasma HIV-1 RNA decay rate or the decay rate of the latently infected cellular reservoir...
  58. ncbi Pre-seroconversion immune status predicts the rate of CD4 T cell decline following HIV infection
    Liselotte van Asten
    Municipal Health Service, Sanquin Research at CLB and Academic Medical Centre and the Department of Human Retrovirology, Academic Medical Centre, Amsterdam, The Netherlands
    AIDS 18:1885-93. 2004
    ..CONCLUSION: Among IDU, immune status prior to HIV infection as measured by TREC content affects the disease course after HIV seroconversion...
  59. ncbi Establishment of the CD4+ T-cell pool in healthy children and untreated children infected with HIV-1
    Mette D Hazenberg
    Department of Clinical Viro-Immunology, Sanquin Research at CLB, Amsterdam, The Netherlands
    Blood 104:3513-9. 2004
    ..We postulate that in children infected with HIV, similar to adults infected with HIV, continuous activation of naive T cells leads to erosion of the naive T-cell pool and may be a major factor in lowering CD4(+) T-cell numbers...
  60. ncbi Altered EBV viral load setpoint after HIV seroconversion is in accordance with lack of predictive value of EBV load for the occurrence of AIDS-related non-Hodgkin lymphoma
    Erwan R Piriou
    Department of Clinical Viro-Immunology, Sanquin Research at CLB and Landsteiner Laboratory. Department of Human Retrovirology and Department of Hematology, Academic Medical Center, University of Amsterdam, Amsterdam, The Netherlands
    J Immunol 172:6931-7. 2004
    ..These data may thus help to explain the lack of predictive value of EBV load for the occurrence of AIDS-related lymphoma...
  61. ncbi Selective decrease in circulating V alpha 24+V beta 11+ NKT cells during HIV type 1 infection
    Hans J J van der Vliet
    Department of Medical Oncology, Pathology, and Internal Medicine, Free University Medical Center, De Boelelaan 1117, 1081 HV Amsterdam, The Netherlands
    J Immunol 168:1490-5. 2002
    ..In this longitudinal study no evidence was found to support an important role of Valpha24+Vbeta11+ NKT cells in determining the rate of progression during HIV-1 infection...
