Who Gets Severe Gynecomastia Among HIV-Infected Children In The UK And Ireland?

There are few data on gynecomastia in HIV-infected children. Within the UK/Ireland's national cohort, 56/1,873 (3%) HIV-infected children had gynecomastia, of which 10 (0.5%) were severe. All 10 had received antiretroviral therapy for a median of 27.5 [21,42] months; 4/10 had received efavirenz, 7/10 and 6/10 stavudine and/or didanosine respectively. Five were non-reversible, despite changing ART, and required breast reduction surgery

Mortality and AIDS-defining events among young people following transition from paediatric to adult HIV care in the UK

OBJECTIVES: To investigate risk of AIDS and mortality after transition from paediatric to adult care in a UK cohort of young people with perinatally acquired HIV. METHODS: Records of people aged ≥ 13 years on 31 December 2015 in the UK paediatric HIV cohort (Collaborative HIV Paediatric Study) were linked to those of adults in the UK Collaborative HIV Cohort (CHIC) cohort. We calculated time from transition to a new AIDS event/death, with follow-up censored at the last visit or 31 December 2015, whichever was the earliest. Cumulative incidence of and risk factors for AIDS/mortality were assessed using Kaplan-Meier and Cox regression. RESULTS: At the final paediatric visit, the 474 participants [51% female, 80% black, 60% born outside the UK, median (interquartile range) age at antiretroviral therapy (ART) initiation = 9 (5-13) years] had a median age of 18 (17-19) years and CD4 count of 471 (280-663) cell/μL; 89% were prescribed ART and 60% overall had a viral load ≤ 400 copies/mL. Over median follow-up in adult care of 3 (2-6) years, 35 (8%) experienced a new AIDS event (n = 25) or death (n = 14) (incidence = 1.8/100 person-years). In multivariable analyses, lower CD4 count at the last paediatric visit [adjusted hazard ratio = 0.8 (95% confidence interval: 0.7-1.0)/100 cells/μL increment] and AIDS diagnosis in paediatric care [2.7 (1.4-5.5)] were associated with a new AIDS event/mortality in adult care. CONCLUSIONS: Young people with perinatally acquired HIV transitioning to adult care with markers of disease progression in paediatric care experienced poorer outcomes in adult care. Increased investment in multidisciplinary specialized services is required to support this population at high risk of morbidity and mortality

Evolution of CD4 T-Cell count with age in a cohort of young people growing up with perinatally acquired HIV

Background: Recent studies have shown a decrease in CD4 count during adolescence in young people with perinatally acquired HIV (PHIV). We examine changes and predictors of CD4 over time in PHIV in the UK and compare to published CD4 data in the general population.// Methods: PHIV followed in the Collaborative HIV Paediatric Study who started antiretroviral therapy (ART) from 2000 onwards were included. Follow-up data from the UK Collaborative HIV Cohort Study were also used. Changes in CD4 count over time from age 10 to 20 years were analysed using mixed effects models. Potential predictors included demographics, age at ART start, nadir CD4 z-score (age-adjusted) in childhood and time-updated viral load.// Results: Of 1,258 PHIV included, 669 (53%) were female, median [IQR] age at ART initiation was 8.3 years [3.5, 12.1] and nadir CD4 z-score was -4.0 [-5.9, -2.5]. In multivariable analysis, mean CD4 count was higher in PHIV who started ART before age 10 and had a nadir CD4 z-score ≥-4 in childhood; these PHIV had a decline in CD4 count after age 10 which was comparable to the general population. Mean CD4 count was lower in PHIV who had started ART before age 10 and had a nadir CD4 z-score <-4 in childhood; for this group the decline in CD4 count after age 10 was steeper over time.// Conclusions: In children, as well as starting ART at an early age, optimising ART to maintain a higher CD4 z-score during childhood may be important to maximize immune reconstitution later in life

Prevalence, incidence, and associated risk factors of tuberculosis in children with HIV living in the UK and Ireland (CHIPS): a cohort study

BACKGROUND: Tuberculosis is the most common serious co-infection in people living with HIV worldwide, but little is known about its incidence in HIV-infected children living in high-resource settings with low tuberculosis prevalence. We aimed to assess the incidence and prevalence of tuberculosis in children with HIV living in the UK and Ireland to understand rates, risk factors, and outcomes of the disease in this group. METHODS: We did an analysis of children enrolled in CHIPS, an observational multicentre cohort of children receiving HIV care in the UK and Ireland. We assessed characteristics and prevalence of tuberculosis at baseline, measured incidence of disease through the follow-up period using the CHIPS database, and calculated associated risk factors in these children with multivariable logistic and Cox regression models. FINDINGS: Between Jan 1, 1996, to Sept 18, 2014, data for 1848 children with 14 761 years of follow-up were reported to CHIPS. 57 (3%) children were diagnosed with tuberculosis: 29 children had tuberculosis at presentation (prevalent tuberculosis) and 29 had the disease diagnosed during follow-up (incident tuberculosis), including one child with recurrent tuberculosis events. Median age at diagnosis was 9 years (IQR 5-12). 25 (43%) children had pulmonary tuberculosis, 24 (41%) had extrapulmonary tuberculosis with or without pulmonary involvement, and the remainder (n=9; 16%) had unspecified-site tuberculosis. The overall incidence rate for the follow-up period was 196 cases per 100 000 person-years (95% CI 137-283). In our multivariable model, tuberculosis at presentation was associated with more severe WHO immunological stage at baseline (odds ratio 0·25, 95% CI 0·08-0·74; p=0·0331; for none vs severe) and being born abroad (odds ratio 0·28, 0·10-0·73; p=0·0036; for UK and Ireland vs abroad). Incident tuberculosis was associated with time-updated more severe WHO immunological stage (hazard ratio 0·15, 95% CI 0·06-0·41; p=0·0056; for none vs severe) and older age at baseline (1·11, 0·47-2·63; p=0·0027; for age >10 years vs 5-9 years). INTERPRETATION: Tuberculosis rates in HIV-infected children in the UK and Ireland were higher than those reported in the general paediatric population. Further study is warranted of tuberculosis screening and preventive treatment for children at high-risk of this disease to avoid morbidity and mortality in this population.

Reactivity of Routine HIV Antibody Tests in Children with Perinatally-Acquired HIV-1 in England: Cross Sectional Analysis

We assessed HIV antibody prevalence in children with perinatally-acquired HIV (PaHIV) in England. 18%(10/55) of those starting combination antiretroviral therapy (cART) <6 months of age were seronegative, and had lower viral load at diagnosis and cART start, and fewer viral rebounds, than 45/55 seropositives. Implications for patient selection for HIV cure research, and interpretation of routine antibody testing, are discussed
