Objectives The aim of the study was to explore factors associated with
CD4 percentage (CD4%) reconstitution following treatment interruptions
(TIs) of antiretroviral therapy (ART). Methods Data from paediatric
HIV-infected cohorts across 17 countries in Europe and Thailand were
pooled. Children on combination ART (cART; at least three drugs from at
least two classes) for > 6 months before TI of >= 30 days while aged
CD4% at restart of ART (r-ART) and in the long term (up to 24 months
after r-ART) following the first TI was modelled using asymptotic
regression. Results In 779 children with at least one TI, the median age
at first TI was 10.1 [interquartile range (IQR) 6.4, 13.6] years and
the mean CD4% was 27.3% [standard deviation (SD) 11.0%]; the median
TI duration was 9.0 (IQR 3.5, 22.5) months. In regression analysis, the
mean CD4% was 19.2% [95% confidence interval (CI) 18.3, 20.1%] at
r-ART, and 27.1% (26.2, 27.9%) in the long term, with half this
increase in the first 6 months. r-ART and long-term CD4% values were
highest in female patients and in children aged TI. Long-term CD4% was
highest in those with a TI lasting 1 to <3 months, those with r-ART
after year 2000 and those with a CD4% nadir >= 25% (all P < 0.001).
The effect of CD4% nadir during the TI differed significantly (P =
0.038) by viral suppression at the start of the TI; in children with
CD4% nadir TI, recovery was better in those virally suppressed prior to
the TI; viral suppression was not associated with recovery in children
with CD4% nadir >= 25%. Conclusions After restart of ART following TI,
most children reconstituted well immunologically. Nevertheless, several
factors predicted better immunological reconstitution, including younger
age and higher nadir CD4% during TI.
