'Don't forget the children' - even in a pandemic

Background: BHIVA's 'Don't Forget the Children' and Standards of Care (SoC) documents highlight the importance of routine HIV testing for children of people living with HIV (PLWH). Our HIV service audited child testing in 2008, 2009 and 2010 with 46%, 78% and 82% respectively of children requiring testing having a documented result. Having evolved a child testing pathway and MDT, with dedicated Health Advisor and Paediatric nurse support, we wanted to re-evaluate our child testing performance during the COVID-19 pandemic. Method(s): Newly diagnosed PLWH, 01/08/2020 - 31/12/2021, were identified via our HARS dataset. All 32 identified individuals case notes were reviewed and the relevant auditable outcomes from BHIVA's SoC document used. Result(s): 32/32 (100%) had documented evidence that child testing had been considered within 4 weeks of diagnosis (BHIVA target 95%). 13/32 had a total of 35 children, 29 of whom did not require testing. 20/29 had documented evidence their mother was not living with HIV post childbirth, 9/29 were >18 years and all but 1, not living in the UK, had either tested in sexual health or antenatal settings. 6/35 (17%) children required testing. 6/6 (100%) had a documented test result within 6 months of their parent's diagnosis, 1 of whom tested negative prior to parental diagnosis (BHIVA target 90%). 5/6 tested aged >18 months. 1 child <18 months, whose parent was diagnosed antenatally, awaits final 4th generation testing at 18 months. Conclusion(s): Our service has a robust mechanism in place for asking all newly diagnosed individuals, and those new to our service, about children during their first consultation. Where children without documented evidence of HIV testing are identified our child testing pathway ensures timely investigation and documentation - all child testing was completed within one month of parental diagnosis in this audit sample. Our service surpassed the BHIVA standards for child testing for all new diagnoses during the COVID-19 pandemic. Future planned work includes a re-audit of child testing for those already known to our HIV service. As neither parental status nor child location is static regular enquiry in relation to children needs embedding into routine HIV care. (Table Presented).

Single-centre review of rapid antiretroviral therapy initiation during the COVID-19 pandemic

Background: BHIVA released interim guidance on first line anti-retroviral therapy (ART) initiation during the COVID-19 pandemic, when investigations/follow-up was restricted. Our HIV service didn't restrict follow-up but suspended in-house resistance testing (RT) due to laboratory capacity. Having prescribed 'rapid ART' based on the Northern Algorithm 01/08/2020-01/01/2022 we wanted to evaluate our prescribing during the pandemic. Method(s): All new HIV diagnoses 01/08/2020-31/12/2021 were identified via our HARS dataset. Retrospective casenote review identified ART prescribed, and switches that occurred upon baseline RT availability, to more suitable and/or cost-effective regimes. Result(s): 32 new diagnoses: 11 female, 21 male, median age 41 years (17-81), 10 MSM, 22 Heterosexuals, White British 14, African 9, other 7. Median time to ART initiation 10 days (0-210). Median CD4 count 359 (2-1251), 8 had CD4<200. 7/32 had Primary HIV infection, 5 initiating ART at 1st visit. 30/32 started ART within our service, 1 relocated, 1 initiated abroad. 28/30 started algorithm compliant rapid ART. Of the 2 that delayed, 1 had significant resistance, the other patient choice. 8/30 (27%) 'rapid ART' initiations switched post RT availability. Conclusion(s): All patients initiating ART in our service during the pandemic were algorithm compliant and fulfilled BHIVA recommendations. 7/10 starting Darunavir/ r-based therapy switched to Delstrigo post RT, a more cost-effective STR. Zero patients on Biktarvy switched post RT;implying it's difficult to switch patients from small INSTI-based-STRs. Future work includes comparing our results with other centres and reviewing ART switches post HIV National Prescribing Guide implementation. (Table Presented).

HIV care during the SARS-COV-2 pandemic for Black people with HIV in the UK

Background: The COVID-19 pandemic disproportionally affected black communities but the impact on HIV care in this group remains poorly understood. We evaluated measures of HIV care during the COVID-19 pandemic in the GEN-AFRICA cohort of black people with HIV living in the U.K. Method(s): We evaluated interruptions to HIV care during the COVID-19 pandemic (01/2020-09/2022) in the GENAFRICA cohort at nine UK clinics who provided HIV outcomes for >80% of their participants. We ascertained death, transfers of care, loss to follow up for >12 months, the highest HIV viral load and interruptions to antiretroviral therapy (ART). We evaluated factors associated with the composite outcome of HIV viraemia (viral load >200 c/mL) and/or an ART interruption using logistic regression analysis;factors associated (P<0.1) in univariable analysis were included in the multivariable model. We also summarized reasons for ART interruptions where recorded. Result(s): 2321 participants (mean age 51.3 years;55.8% women;pre-pandemic current/nadir CD4 of 500/204 cells/mm3 and HIV RNA <200 c/mL in 92.3%) were in care on 01/01/2020. Thirty (1.3%) subsequently died, 24 (1.0%) transferred care and 48 (2.1%) became lost to follow up. 523 (22.7%) reported an episode of COVID-19 and 1771 (87.1%) having been vaccinated against SARSCoV- 2. The composite outcome could be evaluated in 2130 (91.8%);259 (11.2%) had a documented HIV VL >200 c/mL, 228 (9.8%) an ART interruption and 325 (14%) had HIV viraemia/ART interruption. In multivariable analysis, older age, a pre-pandemic HIV RNA <200 c/mL and being vaccinated against SARS-CoV-2 were associated with reduced odds of HIV viraemia/ART interruption (Table) while sex, CD4 (current/nadir), comorbid status and having had COVID-19 were not associated. Reasons for ART interruption were available for 52 participants;38% cited domestic logistic reasons, 27% issues related to foreign travel, 19% psychological reasons, 12% lockdown or changes to the daily routine and 4% personal choice. Conclusion(s): During the COVID-19 pandemic, one in seven black people with HIV experienced an ART interruption and/or HIV viraemia. Pre-pandemic measures of suboptimal engagement in care, pandemic restrictions, and wider health beliefs as reflected by COVID-vaccination, contributed to these undesirable HIV outcomes.

Factors associated with severe SARSCOV- 2 infection in people of Black ethnicities living with HIV in the UK

Background: The COVID-19 pandemic has disproportionally affected people of black ethnicities, who have been at greater risk of SARS-CoV-2 acquisition, morbidity and mortality than those of white ethnicity. We describe factors associated with severe COVID-19 infection in the GEN-AFRICA cohort of people of black ethnicities living with HIV in the U.K. Method(s): First reported episodes of COVID-19 up to October 2022 were ascertained by direct questioning and/or medical records review. Pre-pandemic immune-virological and comorbidity status was based on measurements obtained prior to 01/2020 and used to identify risk factors for severe (requiring hospitalisation or resulting in death) COVID-19, using logistic regression Results: COVID-19 status was available for 1806 (72%) of 2503 GEN-AFRICA participants (mean age 49.2 [SD 10.2] years;56% female;80% sub-Saharan African and 14% Caribbean ancestry, median CD4 count 555 [IQR 400-733] cells/mm3;93% undetectable HIV RNA [<200 copies/ mL]);573 (32%) reported a clinical illness consistent with COVID-19;63 (3.5%) experienced severe COVID-19 (hospitalisation 59;death 4). Those who experienced severe COVID-19 were older, more often male, had lower CD4 counts and fewer had undetectable HIV RNA;they more often had prior AIDS, hypertension, diabetes mellitus and chronic kidney disease. Region of ancestry, nadir CD4 count, and obesity were not associated with severe COVID-19. In multivariable analysis, CD4 count <350 cells/mm3, diabetes mellitus and chronic kidney disease were associated with increased odds of severe COVID-19 (Table). Sex and a pre-pandemic HIV RNA were associated with severe disease although this did not reach statistical significance. By October 2022, 1534 (88%) of this sample had received >=1 dose of SARS-CoV-2 vaccine;those who experienced severe COVID-19 were less likely to report vaccination (77% vs. 89%, p=0.01). Conclusion(s): By the end of October 2022, nearly onethird of people of Black ethnicities with HIV in this sample had experienced COVID-19;3.5% had developed severe COVID-19 disease. Pre-pandemic immunovirological and comorbidity status were associated with severe COVID-19. Black populations with less favourable HIV control than observed for GEN-AFRICA participants may have suffered greater COVID-19 morbidity and mortality. (Table Presented).

HIV CARE DURING THE SARS-CoV-2 PANDEMIC IN BLACK PEOPLE WITH HIV IN THE UK
