Estimation of the CD4 cells recovery probability following long term HAART in HIV positive patients using a non-homogenous Markov model

Abstract

Introduction: Previous studies found highly active antiretroviral therapy (HAART) to be associated with improved survival among human immunodeficiency virus (HIV) infected peoples. The longer someone’s CD4 cell count remains low, the higher the risk of complications including those due to AIDS events or Opportunistic infections. Therefore, monitoring patients to maintain their high level of immune deficiency is important.
