ClassiPcation of HIV disease in childrenThere are two diherent classidcation systems in use internationally: the Centres for Disease Control(CDC) and the World Health Organisation (WHO).

These classidcation systems are used for:

• Assessing need for treatment prioritisation• Describing individuals and populations• Surveillance purposes• Research studies (e.g. disease presentation, progression and ehectiveness of treatment)

Both provide valuable prognostic information and aid clinical decision making, including how quickly tostart ART. Both classidcations have several clinical categories/stages and the last one is describing AIDS-dedning conditions (Table 2). Until recently, both had separate classidcations of HIV-related symptomsand conditions for (i) children and (ii) adults and adolescents. In 2014 CDC revised case dednitions andcombined AIDS-dedning conditions for persons of all ages into one.

Table 2. Two classidcations of HIV disease in children

CDC WHO

Clinical categories: Clinical stages:

N: no symptomsA: mild symptomsB: moderateC: severe symptoms / AIDS / HIV infection stage 3

1: no symptoms2: mild symptoms3: advanced symptoms4: severe symptoms / AIDS

Immunological stages: Immunological stages:

1: no/mild impairment2: intermediate3: severe / AIDS

1: no impairment2: mild3: advanced4: severe / AIDS

Paediatric CDC classidcation was drst introduced in 1994. It is widely used in well-resourced countries,where diagnostic tools are readily available. CDC 1994 classidcation subdivided HIV-related clinicalconditions into N, A, B and C categories. CDC C category included severe symptoms and illnesessassociated with late stage of HIV infection (AIDS). CDC now uses a stage system to describe HIV infection:stage 0 is based on a sequence of negative and positive HIV test results indicative of early (primary) HIVinfection (it is an additional stage introduced in 2014), stages 1–3 are categorized on the basis of theCD4+ T-lymphocyte count (Tables 2 and 3). If a person has an AIDS–dedning opportunistic illness, it isconsidered stage 3 regardless of CD4 counts.

WHO has last updated its classidcation in 2007 when in addition to clinical categories immunologicalstages were included. It is widely used in resource-constrained settings (with or without access todiagnostic and laboratory testing).

Abstract

Background: There is limited knowledge about the optimal timing of antiretroviral treat-ment initiation in older children and adolescents.Methods: A total of 20 576 antiretroviral treatment (ART)-naıve patients, aged 1-16 yearsat enrolment, from 19 cohorts in Europe, Southern Africa and West Africa, were included.We compared mortality and growth outcomes for different ART initiation criteria, alignedwith previous and recent World Health Organization criteria, for 5 years of follow-up, ad-justing for all measured baseline and time-dependent confounders using the g-formula.Results: Median (1st;3rd percentile) CD4 count at baseline was 676 cells/mm3 (394; 1037)(children aged ! 1 and < 5 years), 373 (172; 630) (! 5 and < 10 years) and 238 (88; 425)(! 10 and < 16 years). There was a general trend towards lower mortality and bettergrowth with earlier treatment initiation. In children < 10 years old at enrolment, by 5years of follow-up there was lower mortality and a higher mean height-for-age z-scorewith immediate ART initiation versus delaying until CD4 count < 350 cells/mm3 (or CD4%< 15% or weight-for-age z-score < -2) with absolute differences in mortality and height-for-age z-score of 0.3% (95% confidence interval: 0.1%; 0.6%) and -0.08 (-0.09; -0.06) (! 1and < 5 years), and 0.3% (0.04%; 0.5%) and -0.07 (-0.08; -0.05) (! 5 and < 10 years). Inthose aged > 10 years at enrolment we did not find any difference in mortality or growthwith immediate ART initiation, with estimated differences of -0.1% (-0.2%; 0.6%) and -0.03 (-0.05; 0.00), respectively. Growth differences in children aged < 10 years persistedfor treatment thresholds using higher CD4 values. Regular follow-up led to better heightand mortality outcomes.Conclusions: Immediate ART is associated with lower mortality and better growth for upto 5 years in children < 10 years old. Our results on adolescents were inconclusive.

Key words: Antiretroviral treatment, paediatrics, g-formula, causal inference

Key Messages

• We found lower mortality and better growth with immediate versus delayed antiretroviral treatment initiation in chil-

dren < 10 years of age after 5 years of follow-up.

• We showed neither benefits nor harms with immediate treatment initiation in adolescents aged 10-16.

• The best outcomes were observed in European children who attained growth outcomes comparable to HIV-negative

children. The effects for the different ART initiation criteria were similar in Southern Africa, West Africa and Europe.

• Irregular clinic visits led to worse outcomes than with regular follow-up, but the comparative effectiveness of different

ART initiation criteria were not affected.
