Sociobehavioral Risk Factors and Clinical Implications of Late Presentation Among People Living with HIV in the Brazilian Amazon Region.

This study aimed to analyze the prevalence, sociobehavioral factors and clinical-laboratory consequences of late presentation among people living with HIV (PLHIV) in the Brazilian Amazon region. In total, 402 HIV + individuals treated at reference units in Belém city (Pará, Brazil) between 2018 and 2019 were evaluated. Late presentation was defined as a first-collection LTCD4+ count below 350 cells/µL. Sociodemographic, behavioral and clinical data were obtained from questionnaires or medical records. Th1, Th2 and Th17 cytokine profiles were evaluated by flow cytometry. Longitudinal data on viral load, T lymphocytes, and antiretroviral therapy administration were obtained from control and logistic databases. Approximately 52.73% of the participants were late presenters and sought medical care 7-12 + months after their primary HIV diagnosis. Sociobehavioral factors associated with late presentation included illicit drug use for more than 5 years, polyamory, no alcohol consumption, homosexuality, and sexual inactiveness after HIV diagnosis. Clinically, late presentation was associated with coinfection rate; polysymptomatology; high IFN-É£, IL-6 and IL-10 levels; nonresponse to antiretroviral therapy; and virological failure- and tuberculosis coinfection-motivated changes to therapy. In summary, the prevalence of late presentation in Pará in the Brazilian Amazon region is high. Delays in seeking specialized care after a primary HIV diagnosis cause medium/long-term changes in the life expectancy and health of PLHIV.

Multi-level Factors Associated with HIV Late Presentation with Advanced Disease and Delay Time of Diagnosis in South Carolina, 2005-2019.

This study explored individual- and county-level risk factors of late presentation with advanced disease (LPAD) among people with HIV (PWH) and their longer delay time from infection to diagnosis in South Carolina (SC), using SC statewide Enhanced HIV/AIDS Reporting System (eHARS). LPAD was defined as having an AIDS diagnosis within three months of initial HIV diagnosis, and delay time from HIV infection to diagnosis was estimated using CD4 depletion model. 3,733 (41.88%) out of 8,913 adult PWH diagnosed from 2005 to 2019 in SC were LPAD, and the median delay time was 13.04 years. Based on the generalized estimating equations models, PWH who were male (adjusted prevalence ratio [aPR]: 1.22, 95% CI: 1.12 ∼ 1.33), aged 55+ (aPR: 1.76, 95% CI: 1.62 ∼ 1.92), were Black (aPR: 1.09, 95% CI: 1.03 ∼ 1.15) or Hispanic (aPR: 1.42, 95% CI: 1.26 ∼ 1.61), and living in counties with a larger proportion of unemployment individuals (aPR: 1.02, 95% CI: 1.01 ∼ 1.03) were more likely to be LPAD. Among PWH who were LPAD, Hispanic (adjusted beta: 1.17, 95% CI: 0.49 ∼ 1.85) instead of Black (adjusted beta: 0.11, 95% CI: -0.30 ∼ 0.52) individuals had significant longer delay time compared to White individuals. Targeted and sustained interventions are needed for older, male, Hispanic or Black individuals and those living in counties with a higher percentage of unemployment because of their higher risk of LPAD. Additionally, specific attention should be paid to Hispanic individuals due to their longer delay time to diagnosis.

The effect of late presentation on HIV related mortality among adolescents in public hospitals of north showa zone Oromiya, Ethiopia; 2022: a retrospective cohort study.

BACKGROUND: Late human immunodeficiency virus (HIV) diagnosis is the most prominent cause of HIV/AIDS-related mortality and also increases the risk of transmission and spread of the disease in society. Adolescents are the most vulnerable population's age group for HIV infection in several settings, but expanding access to early HIV testing remains a challenge. Consequently, a significant proportion of adolescents are still dying of HIV-related causes, and the current study aimed at assessing the effect of late presentation on HIV-related mortality among adolescents living with HIV. METHODS: An institutional-based retrospective cohort study was conducted from August 21-November 21, 2022, at selected public hospitals in the North Showa Zone of Oromiya, Ethiopia. All adolescents living with HIV who had received no ART and presented for ART follow-up at public hospitals from September 1, 2012, to August 31, 2021, were included in the study. Data entry was done by Epi-data version 3.1.1 software and exported to Stata version 16 for further analysis. Both bi-variable and multivariable analyses were performed using the Cox proportional hazard model to compare the HIV-related mortality of early and late-presented adolescents using an adjusted hazard ratio at a 95% confidence interval (CI). RESULTS: A total of 341 medical records of adolescents were included in the study, contributing an overall incidence rate of 3.15 (95% CI: 2.21-4.26) deaths per 100 person-years of observation throughout the total follow-up period of 1173.98 person-years. Adolescents with late presentation for HIV care had three times the higher hazard of mortality (adjusted hazard ratio (aHR) = 3.00; 95% CI: 1.22-7.37) as compared to those with early presentation for HIV/AIDS care. Adolescents within the age range of 15-19 years old (aHR = 3.56; 95% CI: 1.44-8.77), rural residence (aHR = 2.81; 95% CI: 1.39-5.68), poor adherence to ART (aHR = 3.17; 95% CI: 1.49-6.76), and being anemic (aHR = 3.09; 95% CI: 1.52-6.29) were other independent predictors of HIV-related mortality. CONCLUSION: The study found a substantial link between HIV late presentation to care and mortality among adolescents. Residence, age, antiretroviral therapy (ART) medication adherence, and anemia status were also found to be other independent predictors of HIV-related mortality. To achieve the ultimate aim of lowering mortality among adolescents living with HIV, rigorous emphasis must be placed on early presentation for HIV/AIDS care. In addition, counseling on adherence and prompt diagnosis and treatment of anemia are highly recommended to reduce mortality.

Enhancing indicator condition-guided HIV testing in Taiwan: a nationwide case-control study from 2009 to 2015.

BACKGROUND: Although indicator condition (IC)-guided HIV testing (IC-HIVT) is effective at facilitating timely HIV diagnosis, research on IC categories and the related HIV risk in Taiwan is limited. To improve the adoption and spread of IC-HIVT in Taiwan, this study compared the IC categories of people living with HIV (PLWH) and non-HIV controls and investigated delays in the diagnosis of HIV infection. METHODS: This nationwide, retrospective, 1:10-matched case-control study analyzed data from the Notifiable Diseases Surveillance System and National Health Insurance Research Database to evaluate 42 ICs for the 5-year period preceding a matched HIV diagnostic date from 2009 to 2015. The ICs were divided into category 1 ICs (AIDS-defining opportunistic illnesses [AOIs]), category 2 ICs (diseases associated with impaired immunity or malignancy but not AOIs), category 3 ICs (ICs associated with sexual behaviors), and category 4 ICs (mononucleosis or mononucleosis-like syndrome). Logistic regression was used to evaluate the HIV risk associated with each IC category (at the overall and annual levels) before the index date. Wilcoxon rank-sum test was performed to assess changes in diagnostic delays following an incident IC category by HIV transmission routes. RESULTS: Fourteen thousand three hundred forty-seven PLWH were matched with 143,470 non-HIV controls. The prevalence results for all ICs and category 1-4 ICs were, respectively, 42.59%, 11.16%, 15.68%, 26.48%, and 0.97% among PLWH and 8.73%, 1.05%, 4.53%, 3.69%, and 0.02% among non-HIV controls (all P < 0.001). Each IC category posed a significantly higher risk of HIV infection overall and annually. The median (interquartile range) potential delay in HIV diagnosis was 15 (7-44), 324.5 (36-947), 234 (13-976), and 74 (33-476) days for category 1-4 ICs, respectively. Except for category 1 for men who have sex with men, these values remained stable across 2009-2015, regardless of the HIV transmission route. CONCLUSIONS: Given the ongoing HIV diagnostic delay, IC-HIVT should be upgraded and adapted to each IC category to enhance early HIV diagnosis.

Is the definition of late diagnosis correct?

BACKGROUND: The study analysed 1711 patients of the Hospital for Infectious Diseases in Warsaw diagnosed with HIV infection in 2008-2010 and 2016-2018. Research was conducted examining the changes in CD4 cell counts before starting antiretroviral (ARV) treatment in order to find people who were misclassified as late-diagnosed. METHODS: Patients with late diagnosis were distinguished on the basis of the consensus definition. The Mann-Whitney U-test was used to analyse the change in CD4 cell counts before starting ARV treatment. RESULTS: In the years 2008-2010, the CD4 count was remeasured before starting ARV treatment in 90 late-diagnosed patients. The median change in the CD4 count was 22 cells/µL. In 49 of these, the number of CD4 cells spontaneously increased before the start of treatment. We can suspect that these patients were misclassified as late-diagnosed. CONCLUSIONS: The consensus definition of late diagnosis often leads to overestimation of the number of late-diagnosed patients. The crucial problem is a transient decline in the CD4 lymphocyte count in the acute phase of HIV infection. A potential solution is to introduce serum HIV viral load measurement into the definition.

Late diagnosis of HIV infection in Warsaw: Estimating the scale of the problem and demographic trends.

BACKGROUND: Late diagnosis of a significant number of people with HIV remains a problem. This study analysed 1711 patients from the Hospital for Infectious Diseases in Warsaw who were diagnosed with HIV infection in 2008-2010 and 2016-2018. METHODS: Patients with late diagnosis and advanced disease were distinguished on the basis of the consensus definition. In statistical analysis, non-parametric tests were used to compare the groups: the χ2 test for categorized data and the Mann-Whitney U test for the comparison of continuous variables. RESULTS: There were no statistically significant differences in the percentage of patients with early diagnosis, late diagnosis, advanced disease and patients with an indicator disease between the two analysed periods in the Warsaw centre. A much higher percentage of men than women was found. The dominant route of acquisition among newly diagnosed patients and among late presenters in both periods were men who have sex with men (MSM). The highest percentage of patients with late diagnosis was among heterosexual men and the lowest was among MSM in both periods. CONCLUSIONS: The results of the analysis of patients from the Warsaw centre confirmed that late diagnosis of HIV infection continues to be a problem, with no improvement seen over the analysed periods, although the scale of the problem is smaller than in national and European statistics. MSM and heterosexual men appear to be key groups in need of intensified testing.

Evaluation of the late presentation and associated factors of people living with HIV in Turkey.

To identify the frequency of late presentation and late presentation with advanced disease, and associated factors in people living with HIV (PLHIV). Data from PLHIV diagnosed between 2008 and 2021 were retrospectively analyzed. Time of diagnosis (categorized based on key events affecting HIV care continuum e.g., national strategies, HIV guidelines, COVID-19 pandemic) and characteristics of late presenters (LP: CD4 ≤350 cells/mm³ or an AIDS defining event) and late presenters with advanced disease (LPAD: CD4 <200 cells/mm³) were describe. Associations between dependent (LP, LPAD) and independent variables were assessed using univariate/multivariate regression tests and presented as odds ratios (95% confidential interval). Of 1585 individuals (93.7% men), 42.5% were LPs and 19.3% were LPADs. Most common route of transmission was sex between men (54.3%). Non-LPs were younger (30 vs. 34 and 36 years; p < 0.001) and included more men who have sex with men (60.3% vs. 46.3% and 39.5%; p < 0.001). Factors associated with being LP and LPAD were age >30 years, heterosexual/unknown route of transmission (vs. sex between men), diagnosis in 2008-2013 or 2020-2021, (vs. 2014-2019). With reference to Turkish subjects, migrants from Africa had higher odds of being LPAD. LP is still an important health issue in HIV care. Heterosexuality, older age (>30 years), migration from Africa, and the COVID-19 pandemic are associated with delays in HIV presentation in Turkey. These factors need to be considered when developing and implementing policies to enable earlier diagnosis and treatment of PLHIV to achieve UNAIDS 95-95-95 targets.

Differences in Reasons for Late Presentation to HIV Care in Uganda Among Men and Women.

Late presentation to HIV care, i.e., presenting with < 200 CD4 cells/mL, is associated with higher mortality and worse outcomes. Despite that, a quarter of people living with HIV in Uganda still present late to care. We surveyed Ugandans living with HIV who enrolled in clinic ≤ 90 days prior. We compared groups who presented 'late' with CD4 < 200 and 'early' with CD4 > 350, stratifying by sex. We found men who presented late had higher externalized stigma than early presenters. Thirty-six percent of the entire cohort were depressed. Social support was stronger in late presenters versus early, although weak overall. Social support was inversely correlated with depression, with social support dropping as depression increased. Interventions to improve clinic privacy, reduce stigma, improve social support, and help women disclose their HIV status to male partners are needed to reduce late presentation to HIV care.

Socio-demographic and psycho-social determinants of HIV late presentation in Germany - results from the FindHIV study.

Delayed HIV diagnosis at advanced stages of disease remains common (33%-64%). This analysis of the multi-center FindHIV study including newly diagnosed HIV-infected adults in Germany, focused on the potential role of socio-demographic and psychological factors on late diagnosis (formerly "late presentation", AIDS diagnosis or CD4 cells <350/µL). These data were collected from patient profiles, physician-patient interviews and questionnaires. Participating centers (n = 40) represented the diverse health care settings in HIV care and geographic regions. Of 706 newly diagnosed adults (92% male, median age 39 years) between 2019 and 2020, 55% (388/706) were diagnosed late with a median CD4 cell count of 147/µL; 20% (142/706) presented with AIDS. From the physicians' perspective, earlier diagnosis would have been possible in 45% of participants (late versus non-late presentation 58% versus 29%). The most common physician-perceived reason was an underestimated risk for HIV infection by the patient (37%). In multivariable logistic regression analysis, older age, sexual contacts with both sexes as possible route of HIV transmission, being married, and a poor level of knowledge about HIV treatment were found to be associated with a significantly elevated risk for late presentation. Education, employment status, sexual relations, migration background and personality traits were not.Trial registration: German Clinical Trials Register (DRKS00016351).

Factors associated with delayed reporting for surgical care among patients with surgical acute abdomen attended at Muhimbili National Hospital: Tanzania.

BACKGROUND: Surgical acute abdomen is a sudden onset of severe abdominal symptoms (pain, vomiting, constipation etc.) indicative of a possible life-threatening intra-abdominal pathology, with most cases requiring immediate surgical intervention. Most studies from developing countries have focused on complications related to delayed diagnosis of specific abdominal problems like intestinal obstruction or acute appendicitis and only a few studies have assessed factors related to the delay in patients with acute abdomen. This study focused on the time from the onset of a surgical acute abdomen to presentation to determine factors that led to delayed reporting among these patients at the Muhimbili National Hospital (MNH) and aimed to close the knowledge gap on the incidence, presentation, etiology, and death rates for acute abdomen in Tanzania. METHODS: We conducted a descriptive cross-sectional study at MNH, Tanzania. Patients with a clinical diagnosis of the surgical acute abdomen were consecutively enrolled in the study over a period of 6 months and data on the onset of symptoms, time of presentation to the hospital, and events during the illness were collected. RESULTS: Age was significantly associated with delayed hospital presentation, with older groups presenting later than younger ones. Informal education and being uneducated were factors contributing to delayed presentation, while educated groups presented early, albeit the difference was statistically insignificant (p = 0.121). Patients working in the government sector had the lowest percentage of delayed presentation compared to those in the private sector and self-employed individuals, however, the difference was statistically insignificant. Family and cohabiting individuals showed late presentation (p = 0.03). Deficiencies in health care staff on duty, unfamiliarity with the medical facilities, and low experience in dealing with emergency cases were associated with the factors for delayed surgical care among patients. Delays in the presentation to the hospital increased mortality and morbidity, especially among patients who needed emergency surgical care. CONCLUSION: Delayed reporting for surgical care among patients with surgical acute abdomen in underdeveloped countries like Tanzania is often not due to a single reason. The causes are distributed across several levels including the patient's age and family, deficiency in medical staff on duty and lack of experience in dealing with emergency cases, educational level, working sectors, socioeconomic and sociocultural status of the country.

Factors causing delayed presentations of breast cancer among female patients in Sulaimani Governorate, Kurdistan region, Iraq.

BACKGROUND: Since breast cancer (BC) has the best chance of being effectively treated when it is tiny and has not spread, encouraging early disease detection remains a fundamental goal in improving prognosis. OBJECTIVE: To quantify the magnitude of the delay in BC presentation as well as the contributing factors related to this delay. PATIENTS AND METHODS: Data was collected at the Breast Diseases Treatment Clinic, Shar Teaching Hospital, Sulaimani, Iraq from January 2017 to December 2021 of 429 patients. A validated questionnaire was distributed to women about their demographics, health, and general awareness of the disease. The patient delay was calculated by collecting information on when they initially began experiencing symptoms and when they saw a doctor. We also gleaned information about the tumour's clinicopathological features from the patient's medical records. RESULTS: The participants' ages ranged from 24 to 85 years, with a mean of 49.6 ± 11. Most women were middle-aged (53.8%), from urban areas (80.2%), illiterate (41.7%), married (86.5%), housewives (79.0%), given birth to > 4 children (34%), practised breastfeeding (78.8%), and non-smokers (91.4%). Regarding patients' health behaviours, there were highly significant correlations between early and late presentation (p < 0.001). Concerning the patient's awareness of BC symptoms, there were highly significant correlations between early and late presentation (p < 0.001). In addition, the late presentation was strongly correlated with bilateral BC, lymph node involvement, inflammatory BC, grade III BC, and T4 status. CONCLUSIONS: Our findings shed light on possible causes of late presentation and identified those at risk of delayed consultation. Our communities need to be educated about BC, and encouraging them for early detection decreases the incidence of advanced BC.

Causes of late-presenting developmental dislocation of the hip beyond 12 months of age: A pilot study.

Background & objectives: Developmental dysplasia of the hip (DDH), when detected early, can usually be managed effectively by simple methods. A delayed diagnosis often makes it a complex condition to treat. Late presentation of DDH is fairly common in developing countries, and there is scarcity of literature regarding the epidemiology and reason for late presentation. Through this study, we attempted to identify the reasons for late presentation of DDH in children more than 12 months of age. Methods: Fifty four children with typical DDH and frank dislocation of hip in whom treatment was delayed for 12 months or more were included. Parents were interviewed with a pre-structured questionnaire and data were collected for analysis with Microsoft Excel 2016 and SPSS version 26. Results: Diagnostic delay was the most common reason for late presentation and was observed in 52 children (96.2%). The mean age at diagnosis was 24.7 months. The mean age at treatment was 37.3 months with a mean delay of 12.5 months from diagnosis and 22.1 months from initial suspicion. Physician-related factors contributed 55.3 per cent, while family and social issues accounted for 44.7 per cent of overall reasons for diagnostic and treatment delays. Interpretation & conclusions: Late presentation of DDH in walking age is common. Physician- and family-related factors accounted for most of these cases. Failure or inadequate hip screening at birth by the attending physician is a common reason for late diagnosis. The family members were unaware about the disorder and developed suspicion once child started walking with an abnormal gait.

The effect of selective ultrasound screening on the incidence of late presentation of developmental hip dysplasia-a meta-analysis.

Different screening strategies for developmental dysplasia of the hip (DDH) exist. Despite screening efforts, cases of late presentation continue to occur, often necessitating surgery. This systematic review and meta-analysis assess the effect of newborn selective ultrasound screening for DDH on the incidence of late presentation in infants and children, compared to a universal ultrasound strategy. A systematic search across Medline and EMBASE databases was performed between January 1950 and February 2021. A consensus-based evaluation of abstracts led to retrieval of relevant full text, original articles or systematic reviews in English only. These were assessed according to agreed eligibility criteria, and their reference lists were reviewed to identify additional eligible publications. Following final consensus on included publications, data was extracted, analysed and reported as per PRISMA and Prospero (CRD42021241957) guidelines. The 16 eligible studies consisted of 2 randomised controlled trials and 14 cohort studies, published between 1989 and 2014, with a total of 511,403 participants. In total, 121,470 (23.8%) received a neonatal hip ultrasound, of whom 58,086 and 63,384 were part of a selective or a universal ultrasound screening strategy, respectively. The difference in the proportion of late presentation between the universal and selective strategies was 0.0904 per 1,000 (P = 0.047). The time effect, i.e. the difference between early and late presentation defined respectively, as less than and more than 3 months of age, regardless of screening strategy, was not significant (P = 0.272). Although there was variability in study design and reporting, the quality of the evidence, based on the critical appraisal skills programme appraisal tools, was generally good. Compared to universal ultrasound screening for DDH, selective screening resulted in a slightly higher rate of late presentation. Uniformity in design and reporting of DDH studies and a cost-effectiveness analysis are needed.

Analysis of Perioperative and Long-Term Outcomes Among Presentations of Anomalous Left Coronary Artery from the Pulmonary Artery Diagnosed Beyond Infancy Versus During Infancy.

Anomalous Left Coronary Artery from the Pulmonary Artery (ALCAPA) typically presents in infancy; however, there are cases of patients who survive the infant period and present later in life. We aimed to characterize patients with late ALCAPA diagnoses and to assess perioperative and functional outcomes. A retrospective chart review of patients who underwent ALCAPA repair between 1996 and 2020 at Boston Children's Hospital was performed. This cohort was divided into early ALCAPA (< 1 year) and late ALCAPA (≥ 1 year) groups. Perioperative data were collected. Longitudinal functional assessments were made by echocardiography, exercise stress test, and cardiac magnetic resonance imaging. The median age of the late ALCAPA group was 7.6 years with 25% (6/24) of patients over 18 years. The late ALCAPA group was more likely to present as an incidental finding (63%) and required less preoperative intervention compared to the early group. On preoperative echocardiogram, the late ALCAPA group had less moderate or severe mitral regurgitation (16.7% vs 62%, p < 0.001) or left ventricular dysfunction (16.7% vs 89%, p < 0.001) compared to the early group. Reoperation was uncommon, and both groups demonstrated almost complete resolution of mitral regurgitation and left ventricular dysfunction over time. There are important differences between late and early ALCAPA subtypes. Revascularization results in excellent outcomes in both early and late groups, but long-term surveillance of ALCAPA patients is warranted as they may have functional deficits after repair.

Late diagnosis of HIV: An updated consensus definition.

INTRODUCTION: 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. METHODS: 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). RESULTS: 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. CONCLUSIONS: 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.

Delayed HIV diagnosis during the COVID-19 pandemic in Poland: A call for targeted HIV testing for those under suspicion of SARS-CoV-2.

OBJECTIVES: The aim of this study was to analyse patients newly diagnosed with HIV who were originally admitted to hospitals with suspicion of COVID-19. METHODS: This was a retrospective case series undertaken at four sites. Only adults with new HIV diagnosis and COVID-19 exclusion hospitalized in 2020-2021 were included. Demographic, clinical and laboratory data were collected from medical records. RESULTS: Twenty-five patients were included in the analysis: 19 men (76%), 11 of Ukrainian origin (44%). The median age was 38.5 years (range 25-59). The mode of HIV transmission was heterosexual for 11 (44%) patients, eight (32%) were men who have sex with men and three (12%) were people who inject drugs. The median duration of symptoms prior to hospital presentation was 20.6 days (range 3-90). The median number of SARS-CoV-2 tests per patient was 2.62 (range 1-7). All SARS-CoV-2 tests were negative. Screening for HIV was performed on average on the 18th day of hospitalization (range 1-36 days). Twenty-three patients (92%) were late presenters, 22 (88%) had advanced disease, and 19 (76%) were in the AIDS stage. The median CD4 T-cell count was 72 cells/µL (range 3-382). The rate of positive HIV testing at the two sites where it was available for people with suspected COVID-19 was 0.13% (7/5458 during the study period). CONCLUSIONS: We strongly recommend introducing the HIV screening test in the diagnostic algorithm for every patient suspected of having COVID-19, presenting with clinical and/or radiological pulmonary symptoms.

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

OBJECTIVES: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

Factors associated with late presentation for HIV care in adolescents in Spain.

OBJECTIVE: Late presenters (LP) for HIV care are associated with higher morbidity and mortality rates. Our aim was to describe the characteristics associated with LP among adolescents in Spain. Identification of particular features may help in the design of strategies for improvement. METHODS: Late-presenting adolescents diagnosed at 12-19 years of age and enrolled in the Spanish paediatric and adult HIV/AIDS cohorts (CoRIS-CoRISpe) from 2004 to 2019 were selected. LP were defined as those presenting with CD4 count <350 cells/mm3 or an AIDS-defining event in the 6 months following HIV diagnosis. Confirmed low CD4 count in the next 3 months and before antiretroviral treatment initiation defined confirmed LP (cLP). RESULTS: Of 410 adolescents newly diagnosed with HIV, 303 (73.9%) had available data for assessing late presentation. Of these, 34.7% were LP and 23.7% were cLP. The median CD4 count for cLP was 235 cells/mm3 (interquartile range 122-285). In a multivariable analysis, adolescents at the highest risk of late presentation were early adolescents (age 12-14 years; odds ratio [OR] 6.50; 95% confidence interval [CI] 2.61-18.2), middle adolescents (age 15-17 years; OR 1.85; 95% CI 0.92-3.59), and adolescents born abroad (OR 1.71; 95% CI 0.97-3.00), particularly those of African origin (OR 3.08; 95% CI 1.38-6.79). CONCLUSIONS: One-quarter of adolescents presented late for HIV care in Spain. Early adolescents, middle adolescents, and those born abroad presented a sevenfold, twofold, and twofold higher risk of being cLP, respectively. Enhancing the awareness of HIV risk and the access to care, especially for younger and foreign adolescents, could help reduce late presentation and tackle the adolescent HIV epidemic.

Estimation of the determinants for HIV late presentation using the traditional definition and molecular clock-inferred dates: Evidence that older age, heterosexual risk group and more recent diagnosis are prognostic factors.

OBJECTIVES: HIV late presentation (LP) has been increasing in recent years in Europe. Our aim was to investigate the characteristics of LP in Greece using in addition to the traditional definition for LP, the time interval between HIV infection and diagnosis. METHODS: Our nationwide sample included HIV-1 sequences generated from 6166 people living with HIV (PLWH) in Greece during the period 1999-2015. Our analysis was based on the molecularly inferred HIV-1 infection dates for PLWH infected within local molecular transmission clusters of subtypes A1 and B. RESULTS: Analysis of the determinants of LP was conducted using either CD4 counts or AIDS-defining condition at diagnosis or the time from infection to diagnosis. Older age, heterosexual transmission risk group and more recent diagnosis were associated with increased risk for LP. In contrast to previous studies, people who inject drugs (PWID) had a shorter median time to diagnosis (0.63 years) compared to men who have sex with men (MSM) (1.72 years) and heterosexuals (2.43 years). Using HIV infection dates that provide an unbiased marker for LP compared to CD4 counts at diagnosis, which are age-dependent, we estimated that the time to diagnosis increased gradually with age. Migrants infected regionally do not differ with respect to LP status compared to native Greeks. CONCLUSIONS: We demonstrate that older people and heterosexuals are among those at higher risk for LP; and given the growing number of older people among newly diagnosed cases, tailored interventions are needed in these populations.

Barriers to HIV care in Uganda and implications for universal test-and-treat: a qualitative study.

Achieving universal HIV test-and-treat will require targeted interventions for those with worse outcomes, including advanced HIV. We conducted qualitative, semi-structured interviews with healthcare workers (HCWs) and people living with HIV (PLWH) at 5 HIV clinics in Kampala, Uganda, to understand barriers to care. PLWH enrolled started/restarted on HIV treatment ≤3 months prior. PLWH were grouped as 1) "ART-experienced" or those restarted therapy after ≥12 months off, 2) ART naïve CD4 count <100 cells/uL "late presenters" or 3) ART naïve CD4 count >350 cells/uL "early presenters". In-depth interviews were conducted in Luganda, translated, and transcribed verbatim. Between May and August 2017, 58 PLWH and 20 HCWs were interviewed. High stigma and low social support emerged as themes among all as barriers to care. Alcohol abuse was a barrier for men. Fear of domestic violence and abandonment were barriers for women, limiting disclosure of their HIV status to their male partners. Clinic factors such as rapport with staff, distance, efficiency, and privacy impacted care. Future interventions to decrease delayed ART initiation should target stigma and social support. Assisted disclosure, contact tracing, and alcohol abuse treatment should be implemented. Strengthening client support, reducing wait times, and increasing privacy assurances would improve care-seeking behaviors.
