018). Our data show an increased risk of vitamin D deficiency or insufficiency in patients with detectable VL and a Black ethnic background. Among cART regimens, boosted PI monotherapy was associated with a lower risk of vitamin D deficiency or insufficiency.
The more favourable vitamin Z-VAD-FMK D status in former IDUs was probably attributable to a higher frequency of outdoor jobs in this group of patients. “
“With the advent of combined antiretroviral therapy (cART), perinatally HIV-infected children are surviving into adolescence and beyond. However, drug resistance mutations (DRMs) compromise viral control, affecting the long-term effectiveness of ART. The aims of this study were to detect and identify DRMs in a HIV-1 infected paediatric cohort. Paired plasma and dried blood spots (DBSs) specimens were obtained from HIV-1 perinatally infected patients attending find more the Jacobi Medical Center, New York, USA. Clinical, virological and immunological data for these patients were analysed. HIV-1 pol sequences were generated from samples to identify DRMs according to the International AIDS Society (IAS) 2011 list. Forty-seven perinatally infected patients were selected, with a median age of 17.7 years, of whom 97.4% were carrying subtype B. They
had a mean viral load of 3143 HIV-1 RNA copies/mL and a mean CD4 count of 486 cells/μL at the time of sampling. Nineteen patients (40.4%) had achieved undetectable viraemia (< 50 copies/mL) and 40.5% had a CD4 count of > 500 cells/μL. Most of the patients (97.9%) had received cART, including protease inhibitor (PI)-based regimens in 59.6% of cases. The DRM prevalence was 54.1, 27.6 and 27.0% for nucleoside reverse transcriptase inhibitors (NRTIs), PIs and nonnucleoside reverse transcriptase inhibitors (NNRTIs), respectively. Almost two-thirds (64.9%) of the patients harboured DRMs to at least one drug class and 5.4% were triple resistant. The mean nucleotide similarity between plasma and DBS sequences was 97.9%. Identical DRM profiles were present in 60%
of plasma−DBS paired sequences. A total of 30 DRMs were detected in plasma and 26 in DBSs, with 23 present in both. Although more perinatally HIV-1-infected children are reaching adulthood as a result of advances Reverse transcriptase in cART, our study cohort presented a high prevalence of resistant viruses, especially viruses resistant to NRTIs. DBS specimens can be used for DRM detection. “
“We recommend adherence and potential barriers to it are assessed and discussed with the patient whenever ART is prescribed or dispensed (GPP). We recommend adherence support should address both perceptual barriers (e.g. beliefs and preferences) and/or practical barriers (e.g. limitations in capacity and resources) to adherence (GPP). Record in patient’s notes of discussion and assessment of adherence and potential barriers to, before starting a new ART regimen and while on ART. Record in patient’s notes of provision or offer of adherence support.
