Early HIV diagnosis enhances quality-adjusted life expectancy of men who have sex with men living with HIV: A population-based cohort study in Taiwan

BackgroundWhether early HIV diagnosis is beneficial for HIV patients themselves remains uncertain, given the stigma and social discrimination associated with an HIV diagnosis. This study aimed to measure the impact of early HIV diagnosis on quality-adjusted life expectancy (QALE) in comparison with late HIV diagnosis, from real-world data in Taiwan under universal access to antiretroviral therapy (ART). MethodsThis population-based cohort study included 14,570 men who have sex with men (MSM) in the national HIV registry and a quasi-random sample (n = 127) of MSM patients to measure quality of life using the EQ-5D health utility instrument. We integrated quality of life data into the extrapolated cohort survival curve to estimate the QALE in patients with early versus late HIV diagnosis (≤30 days before AIDS diagnosis). Loss-of-QALE were estimated by comparing the cohort with age-, sex-, and calendar-year-matched referents simulated from vital statistics. Difference-in-differences was estimated to quantify the effect of early HIV diagnosis. ResultsEarly HIV diagnosis is associated with a loss-of-life expectancy of 3.11 years, with an average health utility of 0.95, in contrast to those diagnosed late (loss-of-life expectancy 8.47 years, with an average health utility of 0.86). After integration of survival and life quality, early HIV diagnosis results in a reduction of loss-of-QALE by 8.28 quality-adjusted life years among MSM living with HIV. ConclusionsUnder universal access to ART, early HIV diagnosis is highly beneficial for people living with HIV themselves, with a net gain of 8.28 healthy life years compared with those diagnosed late.

Tackling late HIV diagnosis: Lessons from the UK in the COVID-19 era.

Late diagnosis of HIV is associated with increased morbidity and mortality, and an increased risk of non-infectious comorbidities. On a societal level, late diagnosis leads to higher treatment and healthcare costs and is a major driver of HIV transmission. Despite improvements in other areas of the HIV care pathway, late diagnosis remains an individual and public health concern globally. To examine the barriers to HIV testing and highlight successful strategies to improve prompt diagnosis. This review describes the prevalence of late diagnosis in the UK and discusses key factors that contribute to late diagnosis, including the effect of the COVID-19 pandemic. Late HIV diagnosis is lower in the UK than in most other European countries. In this review, pilot projects and ongoing initiatives that have reduced late diagnosis in the UK are highlighted; moreover, further strategies for improving prompt diagnosis are suggested. Insufficient testing is the fundamental reason for late HIV diagnosis, with societal, systemic, and individual factors all contributing to inadequate testing. Improving access to testing, removing barriers to health-seeking behaviour, and ensuring all people with HIV indicator conditions are promptly tested are key to reducing the rates of late diagnosis globally.

Developing critical HIV health literacy: insights from interviews with priority migrant communities in Queensland, Australia

In Australia, surveillance data establish that there are higher rates of late HIV diagnoses among heterosexual migrants from Sub-Saharan Africa and new HIV diagnoses among gay and bisexual men (GBM) from Southeast and Northeast Asia and Latin America. Together, these groups are identified as priority migrant communities in current efforts to eliminate HIV transmissions. HIV health literacy is recognised as a key means of improving access to services and health outcomes. This qualitative paper explores critical HIV health literacy among priority migrant communities in Queensland, Australia. To foreground community voices, peer researchers from priority migrant communities participated in the project design, data collection and analysis, with 20 interviews completed. The findings demonstrate how participants’ engagement with HIV health information and services is highly relational and situated within the framework of sexual health and wellbeing. Participants strategically selected where to seek information and who they trusted to help them appraise this information. They further demonstrated reflective capacities in identifying the contextual barriers that inhibit the development of their HIV health literacy. The findings highlight the need for HIV health promotion strategies that embrace a sex positive approach, promote cultural change, and involve collaboration with general practitioners (GPs).

Feasibility of a selective targeted strategy of HIV testing in emergency departments: a before-after study.

The rates of hidden infection and late diagnosis of HIV still remain high in Western countries. Missed diagnostic opportunities represent the key point in changing the course of the epidemic. To evaluate the feasibility and results of implementation of a selective strategy to test for HIV in the emergency department (ED) in patients with six pre-defined medical situations: sexually transmitted infections, herpes zoster, community-acquired pneumonia, mononucleosis syndrome, practice of chemsex (CS) or request of post-exposure prophylaxis. This quasi-experimental longitudinal study evaluated the pre- and post-implementation results of HIV testing in the six aforementioned clinical scenarios. Patients attended 34 Spanish EDs. The intervention was an intensive educational program and pathways to facilitate and track orders and results were designed. We collected and compared pre- and post-implementation ED census and diagnoses, and HIV tests requested and results. The main outcome was adherence to the recommendations. Secondary outcomes were to evaluate the effectiveness of the program by the rate of positive test and the new HIV diagnoses. Differences between first and second periods were assessed. The magnitude of changes (absolute and relative) was expressed with the 95% confidence interval (CI). HIV tests increasing from 7080 (0.42% of ED visits) to 13 436 (relative increase of 75%, 95% CI from 70 to 80%). The six conditions were diagnosed in 15 879 and 16 618 patients, and HIV testing was ordered in 3393 (21%) and 7002 (42%) patients (increase: 97%; 95% CI: 90-104%). HIV testing significantly increased for all conditions except for CS. The positive HIV test rates increased from 0.92 to 1.67%. Detection of persons with undiagnosed HIV increased from 65 to 224, which implied a 220% (95% CI: 143-322%) increase of HIV diagnosis among all ED comers and a 71% (95% CI: 30-125%) increase of positive HIV tests. Implementation of a strategy to test for HIV in selective clinical situations in the ED is feasible and may lead to a substantial increase in HIV testing and diagnoses.

Prevalence, characteristics and challenges of late HIV diagnosis in Germany: an expert narrative review.

We aimed to review the landscape of late HIV diagnosis in Germany and discuss persisting and emerging barriers to earlier diagnosis alongside potential solutions. We searched PubMed for studies informing the prevalence, trends, and factors associated with late HIV diagnosis in Germany. Author opinions were considered alongside relevant data. In Germany, older individuals, heterosexuals, and migrants living with HIV are more likely to be diagnosed late. The rate of late diagnosis in men who have sex with men (MSM), however, continues to decrease. Indicator conditions less often prompt HIV testing in women and non-MSM. During the COVID-19 pandemic, the absolute number of late diagnoses fell in Germany, but the overall proportion increased, probably reflecting lower HIV testing rates. The Ukraine war and subsequent influx of Ukrainians living with HIV may have substantially increased undiagnosed HIV cases in Germany. Improved indicator testing (based on unbiased assessments of patient risk) and universal testing could help reduce late diagnoses. In patients who receive a late HIV diagnosis, rapid treatment initiation with robust ART regimens, and management and prevention of opportunistic infections, are recommended owing to severely compromised immunity and increased risks of morbidity and mortality. Joint efforts are needed to ensure that UNAIDS 95-95-95 2030 goals are met in Germany. These include greater political will, increased funding of education and testing campaigns (from government institutions and the pharmaceutical industry), continued education about HIV testing by HIV experts, and broad testing support for physicians not routinely involved in HIV care.

Trends and factors associated with initiation of HIV treatment among PLHIV in Jamaica, 2015-2019.

Jamaica did not achieve the UNAIDS 90-90-90 targets in 2020. This study aimed to examine trends and factors associated with uptake of HIV treatment among people living with HIV (PLHIV) in Jamaica and to assess the effectiveness of revised treatment guidelines. This secondary analysis used patient-level data from the National Treatment Service Information System. The baseline sample was 8147 PLHIV initiating anti-retroviral treatment (ART) between January 2015-December 2019. Descriptive statistics were used to summarize demographic and clinical variables and the primary outcome timing of ART initiation. Multivariable logistic regression was used to assess factors associated with ART initiation (same day vs 31+ days), using categorical variables for age group, sex and regional health authority. Adjusted odds ratios and 95% confidence intervals are reported. Most persons initiated ART at 31+ days (n = 3666, 45%) after the first clinic date or on the same day (n = 3461, 43%). Same day ART initiation increased from 37% to 51% over 5 years and was significantly associated with males (aOR = 0.82, CI = 0.74-0.92), 2018 (aOR = 0.66, CI = 0.56-0.77), 2019 (aOR = 0.77, CI = 0.65-0.92). late HIV diagnosis (aOR = 0.3, CI = 0.27-0.33) and viral suppression at the first viral load test (aOR = 0.6, CI = 0.53-0.67). ART initiation at 31+days was associated with 2015 (aOR = 1.21, CI = 1.01-1.45) and 2016 (aOR = 1.30, CI = 1.10-1.53) compared to 2017. Our study shows that same day ART initiation increased between 2015-2019, however it remains too low. Same day initiation was associated with the years after Treat All implementation and late initiation before Treat All, providing evidence of the strategy's success. In order to achieve the UNAIDS targets, there is a need to also increase the number of diagnosed PLHIV retained on treatment in Jamaica. Further studies should be conducted to understand important challenges to accessing treatment as well as differentiated care models to improve treatment uptake and retention.

Sex-based epidemiological and immunovirological characteristics of people living with HIV in current follow-up at a tertiary hospital: a comparative retrospective study, Catalonia, Spain, 1982 to 2020.

BackgroundEpidemiological and immunovirological features of people living with HIV (PLWH) can vary by sex.AimTo investigate, particularly according to sex, characteristics of PLWH who consulted a tertiary hospital in Barcelona, Spain, in 1982-2020.MethodsPLWH, still in active follow-up in 2020 were retrospectively analysed by sex, age at diagnosis, age at data extraction (December 2020), birth place, CD4+ cell counts, and virological failure.ResultsIn total, 5,377 PLWH (comprising 828 women; 15%) were included. HIV diagnoses in women appeared to decrease from the 1990s, representing 7.4% (61/828) of new diagnoses in 2015-2020. From 1997, proportions of new HIV diagnoses from patients born in Latin America seemed to increase; moreover, for women born outside of Spain, the median age at diagnosis appeared to become younger than for those born in Spain, with significant differences observed in 2005-2009 and 2010-2014 (31 vs 39 years (p = 0.001), and 32 vs 42 years (p < 0.001) respectively), but not in 2015-2020 (35 vs 42 years; p = 0.254). Among women, proportions of late diagnoses (CD4+ cells/mm3 < 350) were higher than men (significantly in 2015-2020: 62% (32/52) vs 46% (300/656); p = 0.030). Initially, virological failure rates were higher in women than men, but they were similar in 2015-2020 (12% (6/52) vs 8% (55/659); p = 0.431). Women ≥ 50 years old represented 68% (564/828) of women actively followed up in 2020.ConclusionsWomen still have higher rates of late HIV diagnoses than men. Among currently-followed-up women, ≥ 50 year-olds, who need age-adapted care represent a high percentage. Stratifying PLWH by sex matters for HIV prevention and control interventions.

Real-world data in late presentation of HIV infection in Suzhou, China: Results from four consecutive cross-sectional surveys, 2017-2020.

This study aimed to examine the real prevalence of late presentation of HIV infection and to identify factors associated with late HIV presentation among patients with newly diagnosed HIV/AIDS in Suzhou, China. Patients with newly diagnosed HIV/AIDS who registered in national AIDS surveillance system from 2017 to 2020 were included in this study. Late presentation (LP) of HIV infection was defined as HIV diagnosis with a CD4 count < 350 cells/μL or an AIDS-defining event. Multivariable logistic regression analyses were used to identify factors associated with LP. A total of 2,300 patients were enrolled. 1,325 were classified as late presenters, showing a high percentage of 57.6% (95% CI: 54.5-60.7%) and a rise (P = 0.004) over the four-year period. Patients with newly diagnosed HIV/AIDS who were older than 24 years of age (aOR = 1.549, P = 0.001 for 25-39 years; aOR = 2.389, P < 0.001 for 40 years and older), were Suzhou registered residents (aOR = 1.259, P = 0.026), and were from inpatient and outpatient (aOR = 1.935, P < 0.001) were more likely to be late presentation. This study showed a high percentage and a rise of late presentation of HIV infection among patients with newly diagnosed HIV/AIDS in Suzhou, China, which is a challenge for future prevention and control of AIDS. Targeted measures should be urgently implemented to reduce late HIV diagnosis.

Predict the Effects of Dolutegravir (DTG) Plus Lamivudine (3TC) on Immunological Responses in People Living with HIV (PLWHIV).

Immune recovery in people living with HIV (PLWHIV) is a residual aspect of antiretroviral treatment (ART) in most patients, but in a non-negligible proportion of them, the CD4+ lymphocytes count, or CD4/CD8 ratio remains suboptimal. We performed a model of the immune response after 24 weeks of switching to a 2DR with DTG plus 3TC in a retrospective multicenter cohort of undetectable and experienced patients using significant predictor variables associated with the parameters or situations defined as success and failure. Clinical variables studied were CD4+ and CD8+ lymphocyte count, percentage of CD4, and CD4/CD8 ratio. These parameters were assessed at baseline and 24 weeks after the switch. Based on the evolution of each variable, four categories of immune response and four categories of non-immune response were defined. Immune response was defined as CD4+ count > 500 cells/mm3, %CD4 > 30%, CD8+ count < 1000 cells/mm3 and CD4/CD8 ratio ≥ 0.9. Non-response is just the opposite. In our different models of immunological response, the presence of stage of AIDS (p = 0.035, p = 0.065) and current age over 50 years (p = 0.045) are postulated as statistically significative limiting factors in achieving an improvement in CD4, %CD4, CD8, and CD4/CD8 ratio. Late HIV diagnosis (p = 0.156), without statistical significance, enhanced late the previous variables. In contrast, conditions where patients start with CD4 > 500 cells/mm3 (p = 0.054); CD4 > 30% (p = 0.054, p = 0.084); CD8 < 1000 cells/mm3 (p = 0.018), and CD4/CD8 ≥ 0.9 (p = 0.013, p = 0.09) are detected as stimulating or conducive to DTG plus 3TC treatment success. These models represent a proof of concept that could become a valuable tool for clinicians to predict the effects of DTG plus 3TC on immunological responses prior to the switch in undetectable pre-treated PLWHIV with immune dysfunction. The main predictors for immunological failure were late HIV diagnosis, stage of AIDS, and current age over 50 years. In contrast, starting with a normalized immune status was detected as stimulating or conducive to DTG plus 3TC treatment success.

Universal HIV testing and the impact of late diagnosis on disease stage among adults in urban Ethiopia

BackgroundTreatment as prevention evolved into the universal HIV test-and-treat (UTT) strategy, which entails testing to the general population and treatment to every people living with HIV. We investigated universal testing (UT) performance and its determinants in urban Ethiopia and explore magnitude of late diagnosis and its impact on disease stages.MethodWe used data from the Ethiopia Population Based HIV Impact assessment (EPHIA), conducted in 2017/2018 which was a cross-sectional and household-based study. For current analysis, we considered self-report first diagnosis to estimate universal testing irrespective of their serostatus and also consider HIV LAg avidity vs viral load vs plasma antiretroviral drug level algorithm to categorize the late diagnosis. We finally evaluate disease stages using CD4 count and viral load. A 2-level multilevel mixed-effect logistic regression model was employed. The effects of individual-level predictors were quantified by the estimates from the fixed-effect part of the model with p-value < 0.05.ResultData were collected from 18,926 adults among those 29.4% of people living in Urban Ethiopia were never tested for HIV. Never tested females was 26.4% (95% CI = 25.3; 27.5). Never tested among divorced and widowed were 19.4% (95% CI: 17.3; 21.8) and 28.3% (95% CI: 24.6; 32.2), respectively. Never tested among elderly and youth were high (28.3% among 45–54 years old) to (41.2% among 55–64 years old) to 47.8% among 15–24 years old. Overall, late HIV diagnosis among adults in urban Ethiopia was 25.9% (95% CI: 21.7, 30.2). Late diagnosis varies by region ranged from 38.1% in the Gambella to 5.8% in Benishangul Gumuz. Advanced immune suppression (CD4 count < 350 cells/µl) among newly diagnosed long-term infection were significantly higher compared to those who were recently infected which accounted 47.8% (95%CI = 33.2–52.1) and 30.9% (95%CI = 21.3–32.2), respectively. Moreover, Viral load suppression were significantly lower among those who were late diagnosed 26.1% (95%CI = 13.6–33.8) compared to those of newly infected 89.6% (95%CI = 76.2; 93.4).ConclusionWith the aim of UT for high risk and priority population, the low rate of HIV testing among widowed, elderly, young adolescent and women in urban Ethiopia calls for enhanced HIV testing. Moreover, the low HIV testing and high late diagnosis among the high-burden regions calls for region-specific intervention. Advanced disease stages as a result of the high proportion of late diagnosis may impact on fueling community transmission and hinder treatment outcome among PLHIV.

Using Machine Learning to Establish the Concerns of Persons With HIV/AIDS During the COVID-19 Pandemic From Their Tweets

There are millions of People Living with HIV/AIDS (PLWHA) globally and over the years, addressing their concerns has been topical for many stakeholders. It is a well-known and established fact that PLWHA are at increased risk of victimization and stigmatization. Unfortunately, the world experienced an outbreak of the COVID-19 pandemic that has led to strict social measures in many states. Thus, it is the goal of this research to study the impact that the outbreak and its mitigation measures have had on the PLWHA. Specifically, we sought to highlight their concerns from sentiments expressed on social media based on posted tweets. By combining machine learning (ML) techniques such as textual mining and thematic analysis, we determined 14 major themes as factors that are worth exploring. In this work, we originally extracted 2,839,091 tweets related to HIV/AIDS posted from March 2020 to April 2022. After initially doing data cleaning and preprocessing, we performed topic modeling using the Latent Dirichlet Allocation (LDA) topic model to extract 25 topics that are made up of 30 keywords each. The topics were then narrowed into 14 themes. The paper details the negative, positive, and neutral sentiment polarities which we highlight as concerning. These sentiments were determined using the Valence Aware Dictionary and sEntiment Reasoner (VADER) Sentiment Analysis Library with a 90% F1-score compared to TextBlob which showed a 53% F1-score. The research findings highlight issues affecting PLWHA during and post-pandemic such as high cost of medical care, late diagnosis of HIV, limited access to medications, stigmatization and victimization, absence of testing kits in hospitals, and lack of urgency in the development of vaccines or cure for HIV.

Factors associated with HIV testing in people aged ⩾50 years: an integrated qualitative analysis of patients and healthcare providers.

Older people continue to be disproportionately affected by late HIV diagnosis, which results in increased morbidity and mortality. Despite high acceptance of HIV testing generally, older people are less likely to undergo testing than younger people. Two previous studies have been conducted, one focussing on patient-related and one focussing on clinician-related factors associated with HIV testing in older age (⩾50 years). This study is an integrated analysis from two linked studies - one focussed on patients, and one focussed on clinicians - to understand overlap in views and experiences of HIV testing in older age, to outline the clinical implications of the findings, and to highlight potential interventions to improve testing in this group. This qualitative study utilised semi-structured interviews conducted with 20 clinicians who were not HIV care specialists, but who had recently seen an older person prior to their HIV diagnosis, and 20 people who had been diagnosed late with HIV aged 50+. Interviews were audio recorded, transcribed verbatim and thematically analysed. The combined synthesis reported here was planned a priori as part of a sequential design. Seven clinician- and seven patient-related themes were associated with undergoing HIV testing in older age. This article discusses the four themes that were common to both groups: poor knowledge, incorrect symptom attribution, inaccurate perception of risk, and stigma. Both clinician and patient factors associated with testing will have to be addressed in order to increase HIV testing in older people, and reduce the likelihood of late diagnosis. Findings from overlapping themes suggest several areas for intervention: (1) routine screening as part of existing clinical contacts aimed at older people to eliminate the need to attribute symptoms to HIV or assess risk; (2) specific and tailored education materials for clinicians and older people which utilise appropriate modalities; (3) tailored HIV testing services: either specific clinics for older people at existing sexual health services, or dedicated services in primary care.

Molecular Network Analysis Discloses the Limited Contribution to HIV Transmission for Patients with Late HIV Diagnosis in Northeast China

In the “treat all” era, the high rate of late HIV diagnosis (LHD) worldwide remains an impediment to ending the HIV epidemic. In this study, we analyzed LHD in newly diagnosed people living with HIV (PLWH) and its impact on HIV transmission in Northeast China. Sociodemographic information, baseline clinical data, and plasma samples obtained from all newly diagnosed PLWH in Shenyang, the largest city in Northeast China, between 2016 and 2019 were evaluated. Multivariate logistic regression analysis was performed to identify risk factors associated with LHD. A molecular network based on the HIV pol gene was constructed to assess the risk of HIV transmission with LHD. A total of 2882 PLWH, including 882 (30.6%) patients with LHD and 1390 (48.2%) patients with non-LHD, were enrolled. The risk factors for LHD were older age (≥ 30 years: p < .01) and diagnosis in the general population through physical examination (p < .0001). Moreover, the molecular network analysis revealed that the clustering rate (p < .0001), the fraction of individuals with ≥ 4 links (p = .0847), and the fraction of individuals linked to recent HIV infection (p < .0001) for LHD were significantly or marginally significantly lower than those recorded for non-LHD. Our study indicates the major risk factors associated with LHD in Shenyang and their limited contribution to HIV transmission, revealing that the peak of HIV transmission of LHD at diagnosis may have been missed. Early detection, diagnosis, and timely intervention for LHD may prevent HIV transmission.

Impact of COVID-19 on the Belgian HIV epidemic: slowdown of HIV transmission and testing and adaptation of care

BackgroundTo gain insight into the impact of the COVID-19 pandemic and containment measures on the HIV epidemic and services, this study aims to describe HIV trends in 2020 and compare them with previous years.MethodsBelgian national HIV surveillance data 2017–2020 were analysed for trends in HIV testing, HIV diagnoses, VL measurements, ART uptake and PrEP purchase. Descriptive statistics from 2020 are compared to annual averages from 2017 to 2019 (proportional difference, %).ResultsIn 2020, 725 HIV infections were diagnosed in Belgium (− 21.5% compared to 2019). The decline was most pronounced during the first lockdown in April–May but also present in July–December. The number of HIV tests performed decreased by 17.6% in 2020, particularly in March–May and October–December (− 57.5% in April and -25.4% in November 2020 compared to monthly 2017–19 numbers). Diagnosis of acute HIV infections decreased by 47.1% in 2020 (n = 27) compared to 2019 (n = 51). Late HIV diagnoses decreased by 24.7% (95% CI [− 40.7%; -9.7%]) in 2020 compared to 2019. Of patients in care in 2019, 11.8% interrupted HIV care in 2020 compared to 9.1% yearly in the 3 previous years. The number of HIV patients with VL monitoring per month dropped in March–May 2020, whilst proportions of VL suppression and ART coverage remained above 86% and 98.5% respectively in 2020. PrEP purchases, number of purchasers and starters dropped during April–May 2020 (respectively − 45.7%, − 47.4%, − 77.9% in April compared to February 2020).ConclusionsThe significant decrease in HIV diagnoses in Belgium in 2020 coincided with the COVID-19 pandemic and following containment measures, particularly in April–May during the first lockdown. A slowdown of HIV transmission due to reduced HIV risk exposure is suggested by the halving in diagnosis of acute HIV infections in March-December 2020 compared to the previous year, and the adaptive decrease in PrEP use and PrEP initiation from April onwards. Despite a slight increase in HIV care interruptions, the indicators of quality of HIV care remained stable. Access to prevention, testing and care for all people living with HIV and at risk of acquiring HIV is a priority during and after times of pandemic.

Epidemiology, comorbidities at diagnosis and outcomes associated with HIV late diagnosis from 2010 to 2019 in a Belgian reference centre: A retrospective study.

Our objective was to investigate the demographic factors, comorbidities, and outcomes of patients with a late diagnosis (LD) of HIV in a Belgian HIV reference centre. All patients with HIV who presented for care between 2010 and 2019 were included. They were excluded if time between diagnosis and presentation or first CD4 count exceeded 6months or if they had previously received antiretroviral therapy (ART). LD was defined as a CD4 cell count ≤350/mm3 or an AIDS-defining event at diagnosis. Data were retrospectively collected and included data on demographic variables, cardiovascular risk factors, comorbidities at diagnosis, first prescribed ART, and outcomes. Logistic regression was used to determine factors associated with LD. Of 1078 patients, 427 (39.6%) were LD. In multivariable analysis, the following factors were associated with LD: non-homosexual transmission route, being born in Sub-Saharan Africa (SSA), and age ≥35 years. Prevalence at diagnosis of malignancies, diabetes, and cardiovascular diseases did not differ between non-LD and LD, whereas renal impairment was more frequent in LD. In univariable analysis, high-density lipoprotein (HDL) cholesterol <40 mg/dL and estimated glomerular filtration rate <60 ml/min were associated with LD; in multivariable analysis, only HDL cholesterol <40 mg/dL was associated. Patients with LD experienced more adverse events leading to a switch in ART, virological failure, and death during follow-up. LD remains common in our centre, especially in non-homosexual patients and those born in SSA. Although not associated with an important burden of comorbidities at diagnosis, it still results in poorer outcomes, emphasizing the need to expand coverage and access to HIV testing.

Late diagnosis of HIV: An updated consensus definition.

In recent years, HIV testing frequency has increased, resulting in more people being diagnosed during seroconversion with a temporarily low CD4 count. Using the current consensus definition of late HIV presentation ('presenting for care with a CD4 count < 350 cells/μL or an AIDS-defining event, regardless of CD4 count') these individuals would be incorrectly assigned as being diagnosed late. In spring 2022, a European expert group convened to revise the current late HIV presentation consensus definition. A survey on data availability to apply this revised definition was sent to nominated European focal points responsible for HIV surveillance (n=53). Experts agreed that the updated definition should refer to late HIV diagnosis rather than presentation and include the following addition: People with evidence of recent infection should be reclassified as 'not late', with evidence of recent infection considered hierarchically. The individual must have: (i) laboratory evidence of recent infection; (ii) a last negative HIV test within 12 months of diagnosis; or (iii) clinical evidence of acute infection. People with evidence of being previously diagnosed abroad should be excluded. A total of 18 countries responded to the survey; 83% reported capturing CD4 count and/or AIDS at diagnosis through national surveillance, 67% captured last negative test and/or previous HIV diagnosis, 61% captured seroconversion illness at diagnosis and 28% captured incident antibody results. Accurate data on late diagnosis are important to describe the effects of testing programmes. Reclassification of individuals with recent infection will help to better identify populations most at risk of poor HIV outcomes and areas for intervention.

Impact of COVID-19 on HIV late diagnosis in a specialized German centre.

The ongoing COVID-19 pandemic has been impeding HIV diagnosis and treatment worldwide. Data on the impact of COVID-19 on late diagnosis (LD) in Germany are lacking. Here we present novel data of a single-centre German HIV cohort assessing LD during COVID-19. This is a non-interventional, single-centre retrospective cohort assessing the rate of LD comparing HIV diagnoses pre-COVID-19 with those during the COVID-19 pandemic. New diagnoses between 1 January 2019 and 1 February 2020 were classified as pre-COVID-19, and diagnoses between 1 February 2020 and 1 October 2021 were classified as during COVID-19. Between 1 January 2019 and 1 October 2021, 75 patients presented with newly diagnosed HIV infection, 34 pre-COVID-19 and 41 during COVID-19. LD increased to 83% (n=34/41) during COVID-19 versus 59% (n=20/34) pre-COVID-19, and CDC stage C3 rose to 44% (n=18) versus 27%. Hospitalization rate increased to 49% (n=20) during COVID-19 versus 29% pre-COVID-19, and 12% (n=5) presented with HIV-associated neurological disease, whereas none were observed in the pre-COVID-19 group. The incidence of LD (p=0.020), CD4 count < 350 cells/μL (p=0.037) and < 200 cells/μL (p=0.022) were statistically significantly associated with the ongoing COVID-pandemic. An association with HIV transmission risk was borderline significant (p=0.055). Despite comparable annual rates of new HIV diagnoses, LD has been increasing during the COVID-19 pandemic, resulting in more opportunistic infections and higher hospitalization rates, possibly reflecting pandemic-related shortages in HIV testing and care facilities. Maintaining HIV testing opportunities and access to treatment during a pandemic is crucial so as not to impede WHO elimination goals and so as to prevent an increase in AIDS-related morbidity and mortality.

A re-audit of individuals with a late diagnosis of HIV in 2016 and 2019 in Greater Manchester.

New late HIV diagnosis (CD4 count <350cells/mm3) are higher in North West England compared to the UK average. A Greater Manchester-wide audit into individuals diagnosed with late or very late HIV was conducted in 2016 and re-audited in 2019. Our aim was to gain intelligence into key demographics of late diagnosed individuals across Greater Manchester, review opportunities for earlier diagnosis and determine if key recommendations from the 2016 audit were followed. Individuals were identified from locally kept data or HIV and AIDS Reporting System (HARS) data. A retrospective case note review was performed for each patient using data from local notes, General Practice summary of care records and relevant clinical letters. Data was collected for 2019 and compared to 2016 results. In 2016, nine departments contributed data and 104 individuals were identified as having been diagnosed late. In 2019, seven departments contributed data and 65 individuals were identified as having been diagnosed late. In both years, a greater proportion of males diagnosed late were White British and for females Black African. A greater proportion of late diagnosis occurred in men who have sex with men (MSM) and in heterosexual females. In 2019, a greater proportion of patients had an AIDS-defining illness at time of diagnosis. Whilst in 2016, most patients were asymptomatic. Over one third of patients had a clinical indicator disease in their past medical history, which is an increase in proportion from 2016. The proportion of cases where clinicians felt that there had been probable missed opportunities for earlier diagnosis also increased in 2019. There are continued missed opportunities for earlier diagnosis. We recommend targeted interventions for groups at higher risk of late presentation, education in primary/secondary care regarding clinical indicator conditions, a formal review process for all late diagnosed cases, communication with primary/secondary care if missed opportunities are identified and broader HIV testing especially in high prevalence areas.

Re-assessing the late HIV diagnosis surveillance definition in the era of increased and frequent testing.

Late HIV diagnosis (CD4 <350 cells/mm3 ) is a key public health metric. In an era of more frequent testing, the likelihood of HIV diagnosis occurring during seroconversion, when CD4 counts may dip below 350, is greater. We applied a correction, considering markers of recent infection, and re-assessed 1-year mortality following late diagnosis. We used national epidemiological and laboratory surveillance data from all people diagnosed with HIV in England, Wales, and Northern Ireland (EW&NI). Those with a baseline CD4 <350 were reclassified as 'not late' if they had evidence of recent infection (recency test and/or negative test within 24 months). A correction factor (CF) was the number reclassified divided by the number with a CD4 <350. Of the 32 227 people diagnosed with HIV in EW&NI between 2011 and 2019 with a baseline CD4 (81% of total), 46% had a CD4 <350 (uncorrected late diagnosis rate): 34% of gay and bisexual men (GBM), 65% of heterosexual men, and 56% of heterosexual women. Accounting for recency test and/or prior negative tests gave a 'corrected' late diagnosis rate of 39% and corresponding CF of 14%. The CF increased from 10% to 18% during 2011-2015, then plateaued, and was larger among GBM (25%) than heterosexual men and women (6% and 7%, respectively). One-year mortality among people diagnosed late was 329 per 10 000 after reclassification (an increase from 288/10 000). The case-surveillance definition of late diagnosis increasingly overestimates late presentation, the extent of which differs by key populations. Adjustment of late diagnosis is recommended, particularly for frequent testers such as GBM.
