CD4 and tuberculosis: Known risk factors include disseminated and extrapulmonary TB (Breton et al., 2004, Manosuthi et al., 2006, Burman et al., 2007, Namale et al., 2015), short interval between TB treatment and ART initiation (Burman et al., 2007, Namale et al., 2015, Breen et al., 2004, Olalla et al., 2002), vigorous immunological and virological responses to ART (Breton et al., 2004) and low CD4 count prior to ART initiation (Michailidis et al., 2005, Manosuthi et al., 2006, Lawn et al., 2007).
