Hospitalizations for Acute Otitis and Sinusitis in Patients Living with HIV: A Retrospective Analysis of a Tertiary Center in Romania. J Clin Med 2024; 13:3346. [PMID: 38893057 PMCID: PMC11172890 DOI: 10.3390/jcm13113346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 05/18/2024] [Accepted: 05/30/2024] [Indexed: 06/21/2024] Open
Abstract
Background/Objectives: Acute or chronic ear, nose and throat (ENT) conditions in people living with HIV can lead to hospitalization and affect their quality of life. The aim of our study was to determine the frequency and characteristics of hospitalizations for acute sinusitis (AS) and acute otitis (AO) in people living with HIV. Methods: We performed a retrospective analysis over the course of six years (from January 2018 to December 2023), assessing all hospitalizations for AS and/or AO occurring in patients living with HIV, at the largest infectious diseases hospital in Romania. Results: We identified a total of 179 cases, among which 149 cases (83.2%) were attributed to AS and 41 cases (22.9%) were due to AO. Among cases of AS, maxillary sinuses were most frequently involved (n = 140/149, 94.0%), and among cases of AO, acute congestive otitis media (n = 14, 34.1%) and acute purulent otitis media (n = 13, 31.7%) were the most common forms. The underlying HIV infection was classified as stage C3 in 57.5% of cases. In 19.6% of cases, it was possible to identify either the trigger or the etiological agent, and the most frequent bacterial pathogens were Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae and Pseudomonas aeruginosa. Conclusions: In conclusion, this study highlights that hospitalizations due to acute sinus and ear involvement are not isolated events in people living with HIV. A prospective follow-up is needed to gain a deeper and more dynamic understanding of how ENT health is affected in people with HIV infection. Furthermore, promoting prevention through vaccination may reduce to a certain extent the burden of ENT infections in this population.

Abstract
INTRODUCTION Complex challenges amongst ageing cohorts of adolescents and adults living with perinatally acquired HIV (PaHIV) may impact on hospitalisation. We report hospitalisation rates and explored predictive factors for hospitalisation in adolescents and adults (10-35 years) living with PaHIV in England. METHOD Retrospective observational cohort study over a three-year period 2016-2019. Data collected included cause and duration of hospitalisation, HIV viral load and CD4 lymphocyte count. The primary outcome was overnight hospitalisation. Patients exited at study end/ transfer of care (TOC)/ loss to follow up (LTFU) or death. Maternity/hospital admissions at other centres were excluded. Admission rates per 100 person-years (95% CI) were calculated by age group. Negative binomial regression with generalized estimating equations was performed. RESULTS 255 patients contributed 689 person-years of follow up. 56% were female and 83% were of a Black, Black British, Caribbean or African ethnicity. At baseline, the median age was 19 years (IQR 16-22). 36 individuals experienced a total of 62 admissions which resulted in 558 overnight stays (median stay was 5 nights). One person died (lymphoma), six had TOC and one was LTFU by the end of the three-year study period. Crude incidence of admission for the whole cohort was 9.0 per 100 PY (6.9-11.6). The respective crude incidence rates were 1.5 PY (0.0-8.2) in those aged 10-14 years and 3.5 PY (1.5-7.0) in the 15-19-year-olds. In those aged 20-24 years it was 14.5 PY (10.1-20.2) and in those >25 years the crude incidence rate was 11.7 PY (6.9-18.5). Factors significantly associated with admission were a CD4 lymphocyte count <200 cells/uL, adjusted IRR 4.0 (1.8-8.8) and a history of a CDC-C diagnosis, adjusted IRR 2.9 (1.6-5.3). 89% admissions were HIV-related: 45% new/current CDC-C diagnoses, 76% due to infection. CONCLUSIONS Hospitalisation rates were four-fold higher in adults (>20 years of age) compared to adolescents (10-19-year-olds). The continuing challenges experienced by PaHIV youth require enhanced multidisciplinary support throughout adulthood.

[PMID: 38166819 PMCID: PMC10762994 DOI: 10.1186/s12879-023-08889-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 12/11/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND In the first reported cases of human immunodeficiency virus (HIV) infection, people living with HIV (PLHIV) suffered weight loss, which was an independent predictor of mortality. Highly active antiretroviral therapy (HAART) has changed this scenario for ideal weight, overweight, and even obesity. However, some PLHIV, even on HAART, continue to lose weight. Thus, the guiding question of the study was: do PLHIV hospitalized using HAART with weight loss have higher mortality than hospitalized PLHIV using HAART without weight loss? METHOD A systematic review and meta-analysis of prospective cohort studies published in English, Spanish, or Portuguese, searched in the MedLine, Embase, and LILACS databases from March 2020, until October 2023, reported by MOOSE. We analyzed the methodological quality and risk of bias using the Joanna Briggs Institute Critical Appraisal Tool for Cohort Studies; used the risk ratio (RR) to calculate the probability of hospitalized PLWH who lost weight dying, applied the random effect model and created the funnel plot. We used the inverse variance test estimated by the Mantel-Haenszel method, considering a 95% confidence interval (CI), heterogeneity (I2), total effect size (Z), and significance value of p < 0.05. We performed a sensitivity analysis with meta-regression and meta-analyses on subgroups to diagnose influence and outliers. The quality of evidence and strength of recommendation were analyzed using the Grading of Recommendations Assessment, Development, and Evaluation system (GRADE). RESULTS We included 10 of the 711 studies identified, totaling 1,637 PLHIV. The studies were from South Africa (1), Canada (1), China (1), Brazil (1), Cameroon (1), Ethiopia (1), Thailand (1), Colombia (1), and Tanzania (2), from 1996 to 2017. The average age of the participants was 33.1 years old, and the male was predominant. The leading causes of hospital admission were related to co-infections, and the average hospitalization time was 20.5 days. The prevalence of death in hospitalized PLHIV using HAART who lost weight was 57.5%, with a 1.5 higher risk of dying (RR: 1.50, 95% CI: 1.03, 2.19, p = 0.04) than hospitalized PLHIV who did not lose weight. CONCLUSION We concluded, with a very low confidence level, that that weight loss significantly increased the risk of death in hospitalized PLWH using HAART.

Abstract
BACKGROUND Understanding demographic disparities in hospitalisation is crucial for the identification of vulnerable populations, interventions, and resource planning. METHODS Data were from the Antiretroviral Therapy Cohort Collaboration (ART-CC) on people living with HIV in Europe and North America, followed up between January, 2007 and December, 2020. We investigated differences in all-cause hospitalisation according to gender and mode of HIV acquisition, ethnicity, and combined geographical origin and ethnicity, in people living with HIV on modern combination antiretroviral therapy (cART). Analyses were performed separately for European and North American cohorts. Hospitalisation rates were assessed using negative binomial multilevel regression, adjusted for age, time since cART intitiaion, and calendar year. FINDINGS Among 23 594 people living with HIV in Europe and 9612 in North America, hospitalisation rates per 100 person-years were 16·2 (95% CI 16·0-16·4) and 13·1 (12·8-13·5). Compared with gay, bisexual, and other men who have sex with men, rates were higher for heterosexual men and women, and much higher for men and women who acquired HIV through injection drug use (adjusted incidence rate ratios ranged from 1·2 to 2·5 in Europe and from 1·2 to 3·3 in North America). In both regions, individuals with geographical origin other than the region of study generally had lower hospitalisation rates compared with those with geographical origin of the study country. In North America, Indigenous people and Black or African American individuals had higher rates than White individuals (adjusted incidence rate ratios 1·9 and 1·2), whereas Asian and Hispanic people living with HIV had somewhat lower rates. In Europe there was a lower rate in Asian individuals compared with White individuals. INTERPRETATION Substantial disparities exist in all-cause hospitalisation between demographic groups of people living with HIV in the current cART era in high-income settings, highlighting the need for targeted support.

Abstract
OBJECTIVE People with HIV infection experience excessive mortality compared with their noninfected counterparts. It is unclear whether the impact of HIV infection on mortality varies by comorbidities or whether sex difference exists in this relationship. This study assessed the effect of newly diagnosed HIV infection on overall mortality among Medicare beneficiaries for both disabled and older adults (≥65 years old) based on their original entitlement. METHODS We constructed a retrospective matched cohort using a 5% nationally representative sample of Medicare beneficiaries between 1996 and 2015. People with incident HIV diagnoses were individually matched to up to three controls based on demographics. Cox proportional hazards models adjusted for baseline demographics and comorbidities were used to assess the effect of HIV status on survival among four disabled groups by sex strata. Within each stratum, interactions between comorbidity variables and HIV status were examined. RESULTS People with HIV, especially older women, had a higher prevalence of baseline comorbidities than controls. HIV--mortality association varied according to sex in older adults (P = 0.004). Comorbidity--HIV interactions were more pronounced in disabled groups (P < 0.0001). People with HIV with more chronic conditions had a less pronounced increase in the risk of death than those with fewer conditions, compared with uninfected controls. CONCLUSION Medicare enrollees with newly diagnosed HIV had more prevalent baseline comorbidities and were at higher risk of death than people without HIV. HIV infection has a more pronounced effect among those with fewer comorbidities. Sex differences in HIV--mortality association exist among older Medicare enrollees.

Causes of hospitalisation among a cohort of people with HIV from a London centre followed from 2011 to 2018. BMC Infect Dis 2021; 21:395. [PMID: 33926373 PMCID: PMC8082756 DOI: 10.1186/s12879-021-06082-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 04/15/2021] [Indexed: 12/12/2022] Open
Abstract
Background We describe the spectrum of ICD-10 classified causes for hospitalisations occurring between 2011 and 2018 in a cohort of people living with HIV (PLHIV). Methods This sub-study includes 798 PLHIV participating in the Antiretroviral, Sexual Transmission Risk and Attitudes (ASTRA) questionnaire study who were recruited from a large London centre. A medical record review identified the occurrence and causes of hospitalisation from the date of questionnaire completion (February–December 2011) until 1 June 2018. Up to five causes were classified by an HIV clinician using the ICD-10 system. Results There were 274 hospitalisations in 153 people (rate = 5.8/100 person-years; 95% CI: 5.1, 6.5). Causes were wide-ranging; the most common were circulatory (16.8%), digestive (13.1%), respiratory (11.7%), infectious diseases (11.0%), injury/poisoning (10.6%), genitourinary diseases (9.9%) and neoplasms (9.1%). A tenth (27/274) of hospitalisations were related to at least one AIDS-defining illness. Median duration of hospitalisation was 5 days (IQR 2–9). At the time of hospitalisation, median CD4 count was high (510 cells/μl; IQR: 315–739), while median CD4 nadir was relatively low (113 cells/μl; IQR: 40–239). At admission, half of individuals (51%) had a previous AIDS-defining illness and 21% had viral load > 50 copies/ml. Individuals admitted for infectious diseases were particularly likely to have unfavourable HIV-related clinical characteristics (low CD4, viral non-suppression, not on antiretroviral therapy (ART), previous AIDS). Conclusions In the modern combination antiretroviral therapy era, the spectrum of causes of hospitalisation in PLHIV in the UK is wide-ranging, highlighting the importance of holistic care for PLHIV, including prevention, early detection and treatment of comorbidities.
