CD4 Trends With Evolving Treatment Initiation Policies Among Children Living With HIV in Zambézia Province, Mozambique, 2012–2018

BACKGROUND: Historically, antiretroviral therapy (ART) initiation was based on CD4 criteria, but this has been replaced with "Test and Start" wherein all people living with HIV are offered ART. We describe the baseline immunologic status among children relative to evolving ART policies in...

Sumario:BACKGROUND: Historically, antiretroviral therapy (ART) initiation was based on CD4 criteria, but this has been replaced with "Test and Start" wherein all people living with HIV are offered ART. We describe the baseline immunologic status among children relative to evolving ART policies in Mozambique. METHODS: This retrospective evaluation was performed using routinely collected data. Children living with HIV (CL aged 5–14 years) with CD4 data in the period of 2012–2018 were included. ART initiation “policy periods” corresponded to implementation of evolving guidelines: in period 1 (2012–2016), ART was recommended for CD4 <350 cells/mm(3); during period 2 (2016–2017), the CD4 threshold increased to <500 cells/mm(3); Test and Start was implemented in period 3 (2017–2018). We described temporal trends in the proportion of children with severe immunodeficiency (CD4 <200 cells/mm(3)) at enrollment and at ART initiation. Multivariable regression models were used to estimate associations with severe immunodeficiency. RESULTS: The cohort included 1815 children with CD4 data at enrollment and 1922 at ART initiation. The proportion of children with severe immunodeficiency decreased over time: 20% at enrollment into care in period 1 vs. 16% in period 3 (P = 0.113) and 21% at ART initiation in period 1 vs. 15% in period 3 (P = 0.004). Children initiating ART in period 3 had lower odds of severe immunodeficiency at ART initiation compared with those in period 1 [adjusted odds ratio (aOR) = 0.67; 95% CI: 0.51 to 0.88]. Older age was associated with severe immunodeficiency at enrollment (aOR = 1.13; 95% CI: 1.06 to 1.20) and at ART initiation (aOR = 1.14; 95% CI: 1.08 to 1.21). CONCLUSIONS: The proportion of children with severe immunodeficiency at ART initiation decreased alongside more inclusive ART initiation guidelines. Earlier treatment of children living with HIV is imperative.
