The 2015 Paediatric European Network for Treatment of AIDS (PENTA) guidelines provide practical recommendations on the management of HIV‐1 infection in children in Europe and are an update to those published in 2009. Aims of treatment have progressed significantly over the last decade, moving far beyond limitation of short‐term morbidity and mortality to optimizing health status for adult life and minimizing the impact of chronic HIV infection on immune system development and health in general. Additionally, there is a greater need for increased awareness and minimization of long‐term drug toxicity. The main updates to the previous guidelines include: an increase in the number of indications for antiretroviral therapy (ART) at all ages (higher CD4 thresholds for consideration of ART initiation and additional clinical indications), revised guidance on first‐ and second‐line ART recommendations, including more recently available drug classes, expanded guidance on management of coinfections (including tuberculosis, hepatitis B and hepatitis C) and additional emphasis on the needs of adolescents as they approach transition to adult services. There is a new section on the current ART ‘pipeline’ of drug development, a comprehensive summary table of currently recommended ART with dosing recommendations. Differences between PENTA and current US and World Health Organization guidelines are highlighted and explained.

“…[6] Other than phase 2 trials under controlled conditions, two other retrospective studies involving treatment-experienced adolescents in Spain receiving RALor ETR-based regimens in combination with other ARVs have found comparable safety and efficacy outcomes. [7,8,[10][11][12] Although GRT is a prerequisite for accessing these medications in the SA public sector, specific indications for resistance testing are not included in the 2014 national guidelines, and access to GRT has not been uniform in the SA public sector. Before 2015, GRT was generally only available to patients with private medical insurance or through research studies or donor-funded access programmes in the public sector.…”

RESEARCHBy 2012, the estimated number of children (0 -14 years of age) receiving antiretroviral therapy (ART) in South Africa (SA) was 140 541, representing an estimated 63% of those requiring treatment. [1,2] As increasing numbers of children are started on first-and second-line ART, the demand for third-line regimens in children and adolescents with treatment failure is likely to increase. It is estimated that currently <1% of people on ART globally are receiving third-line regimens, and it is unknown what proportion of these are children. [3] An unpublished systematic review presented in 2015 assessing second-and third-line ART options for children and adolescents concluded that there is insufficient evidence to directly evaluate alternative second-and third-line ART options for children, and that current recommendations are still based on inference from adult trials.[4] The World Health Organization (WHO) recommends that national programmes should develop policies for third-line ART that should incorporate integrase strand transfer inhibitors (INSTIs), second-generation protease inhibitors (PIs) and secondgeneration non-nucleoside reverse transcriptase inhibitors (NNRTIs) with minimal risk of cross-resistance to previously used regimens. Recommended third-line ART regimens in the WHO 2016 guidelines [5] are: (i) darunavir/ritonavir (DRV/r) plus dolutegravir (DTG) (or raltegravir (RAL)) with or without one to two nucleoside reverse transcriptase inhibitors (NRTIs); (ii) DRV/r plus two NRTIs with or without one NNRTI; or (iii) RAL (or DTG) plus two NRTIs, depending on the preceding first-and second-line ART regimens.Although safety and efficacy of DRV/r, etravirine (ETR) and RAL have been reported in specific age groups of ART-naive and ARTexperienced children and adolescents, there is a paucity of data on treatment-experienced children from resource-constrained settings receiving these drugs as part of routine care. [6][7][8][9][10][11][12][13][14] In addition, DRV/r is not recommended in children <3 years of age owing to toxicity concerns in animal studies, and ETR, a second-generation NNRTI, is not recommended in children <6 years of age owing to lack of safety and efficacy data. Until very recently, DTG was only recommended by the US Food and Drug Administration (FDA) for adolescents >12 years of age and >40 kg body weight.[15] The FDA has recently approved DTG from 6 to <12 years and ≥30 kg in a dose of 35 mg once daily, but suitable formulations that allow for administration of this dose are not yet registered in SA.[16] In SA, DTG has only been approved from 18 years of age. ObjectiveTo describe the characteristics and early outcomes of treatmentexperienced children and adolescents (<20 years of age) in the Western Cape Province of SA who initiated an ART regimen that included one or more of DRV/r, RAL and ETR. Background. There is an increasing need for third-line treatment regimens in HIV-infected children with antiretroviral treatment (ART) failure. Data are limited on darunavir/ritonavir (DRV/r)-, r...

“…In another trial, RAL was evaluated as part of a salvage treatment in a multicenter retrospective study of 19 MDR children and adolescents. After receiving RAL-based therapy, 4/19 (21%) patients achieved an HIV-1 RNA load of (15). In this study, a mild increase in lipids was found, but this was not statistically significant, maybe because of the previous use of other PIs having a worse effect on lipids.…”

Genotype-guided antiretroviral regimens in children with multidrug-resistant HIV-1 infection

et al. 2016

View full text Add to dashboard Cite

Background: Genotyping tests were developed to attenuate the impact of viral resistance. Information about the efficacy in genotype base antiretroviral therapy in children is rare and even more in low-and middle-income countries. Methods: Sixteen children with antiretroviral therapy (ART) failure and triple-class drug-resistant viruses were included in this study. Protease and retrotranscriptase genotypes were available for all patients. Switch of ART regimen was guided by genotyping data. The primary end point was virological suppression (<50 copies/ml) and immunological improvement after 48 wk of treatment with the new ART regimen. results: The median age of the patients was 14.5 y (interquartile range (IQR) 11-16.5). Median HIV-1 RNA viral load was 4.2 log 10 (IQR: 3.4-4.8). The primary end point was found in 11 children (69%), and 13 children (81%) had an HIV-1 RNA viral load <200 copies/ml. Median (IQR) for the baseline CD4 + cell count was 382 cells/μl (281-686 cells/μl), whereas after 48 wk of treatment with the new ART regimen, it was 640 cells/μl (361-936 cells/μl) (P < 0.001). conclusion: Darunavir/ritonavir, raltegravir, and etravirine were well tolerated in the present pediatric population. These drugs provide good options for children exposed to extensive ART. Regimens guided by genotyping data were effective for children who had ART failure and multidrug-resistant HIV-1 infection.i nfants and children who were infected perinatally are now surviving to adulthood with lifelong HIV infection and longterm exposure to combined antiretroviral therapy (ART) (1). Data from the United Kingdom Collaborative HIV Pediatric Study cohort demonstrated that over one-third of children had experienced virological treatment failure and were on a second or subsequent line of therapy at the time of their transition to adult care (2). In the pediatric setting, virological treatment failure occurs most frequently because of poor adherence to ART, and whenever viral replication is inefficiently controlled, virological treatment failure occurs more quickly, allowing the selection of HIV-1 quasispecies resistant to antiretroviral (ARV) drugs (3).Many innate and external factors have been associated with HIV drug resistance mutations in children, such as being infected perinatally, and extremely high viral load during the first steps of the infection, which can take longer to suppress than that in older children or adults, even when they are on fully active ART regimens (4).Interpretation of resistance tests in this context can be complex, particularly in the presence of expanding options for ARV drugs, and treatment decisions should be made with the support of pharmacists and clinicians who have expertise in the field (5).Currently, more than 20 different ARV drugs with six different classes of action have been approved for use in children or adolescents with HIV infection worldwide; most of them are used in Mexico (6).A good level of adherence is particularly difficult during adolescence, especially with a complex regimen ...
