Risk of breakthrough infection and hospitalisation after COVID-19 primary vaccination by HIV status in four Italian regions during 2021. BMC Public Health 2024; 24:1569. [PMID: 38862939 PMCID: PMC11165887 DOI: 10.1186/s12889-024-19071-y] [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: 02/29/2024] [Accepted: 06/06/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND As of 2024, vaccination remains the main mitigation measure against COVID-19, but there are contradictory results on whether people living with HIV (PLWH) are less protected by vaccines than people living without HIV (PLWoH). In this study we compared the risk of SARS-CoV-2 infection and COVID-19 hospitalisation following full vaccination in PLWH and PLWoH. METHODS We linked data from the vaccination registry, the COVID-19 surveillance system and from healthcare/pharmacological registries in four Italian regions. We identified PLWH fully vaccinated (14 days post completion of the primary cycle) and matched them at a ratio of 1:4 with PLWoH by week of vaccine administration, age, sex, region of residence and comorbidities. Follow-up started on January 24, 2021, and lasted for a maximum of 234 days. We used the Kaplan-Meier estimator to calculate the cumulative incidence of infection and COVID-19 hospitalisation in both groups, and we compared risks using risk differences and ratios taking PLWoH as the reference group. RESULTS We matched 42,771 PLWH with 171,084 PLWoH. The overall risk of breakthrough infection was similar in both groups with a rate ratio (RR) of 1.10 (95% confidence interval (CI):0.80-1.53). The absolute difference between groups at the end of the study period was 8.28 events per 10,000 person-days in the PLWH group (95%CI:-18.43-40.29). There was a non-significant increase the risk of COVID-19 hospitalisation among PLWH (RR:1.90; 95%CI:0.93-3.32) which corresponds to 6.73 hospitalisations per 10,000 individuals (95%CI: -0.57 to 14.87 per 10,000). CONCLUSIONS Our findings suggest PLWH were not at increased risk of breakthrough SARS-CoV-2 infection or COVID-19 hospitalisation following a primary cycle of mRNA vaccination.

Regional differences in perceived treatments needs and priorities in relation to antiretroviral therapy among people living with HIV in 25 countries. Prev Med 2021; 142:106372. [PMID: 33333128 DOI: 10.1016/j.ypmed.2020.106372] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 09/21/2020] [Accepted: 12/10/2020] [Indexed: 02/06/2023]
Abstract
While geographic differences in HIV burden are well documented, less is known about regional differences in perceived treatment needs. To fill this gap, the 2019 Positive Perspectives study of people living with HIV (PLHIV) was conducted in 25 countries across Northern America, Latin America, the Asian region, Europe (EU/Schengen countries), Russia, Australia, and South Africa (n = 2389). Overall mean duration of HIV was 10.1 (SD = 9.6) years. The perception that HIV had a negative impact on day-to-day life was lowest among participants from South Africa (14.0%[25/179]) and highest among participants from the Asian region (55.2%[127/230]). Most of the regional gap in the perception that HIV had a negative impact on daily life was explained by regional differences in medication-related unmet needs, stigma, demographic factors, and comorbidities. The percentage who felt they understood their treatment was highest among participants from Australia (87.5%[105/120]) and lowest among those from Russia (62.0%[93/150]), the Asian region (62.2%[143/230]), and South Africa (62.6%[112/179]). Among participants from Northern America, Europe, and Latin America, the treatment goals with the largest absolute increase in perceived importance, from time of starting treatment to time of survey among those diagnosed for ≥1 year, were minimizing the long term impact of antiretroviral treatment and keeping the number of medicines in their antiretroviral regimen at a minimum. Tailored approaches to care of PLHIV are needed as different regions have different disease burden and treatment needs. Equitable approaches to HIV care are needed across and within regions to ensure that patients' unmet needs and preferences are addressed to improve their overall wellbeing and health-related quality of life.

Mediterr J Hematol Infect Dis 2020; 12:e2020017. [PMID: 32180912 PMCID: PMC7059746 DOI: 10.4084/mjhid.2020.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Accepted: 02/14/2020] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Despite progress in the prevention and treatment of HIV, persistent issues concerning the evaluation of continuum in care from the serological diagnosis to virologic success remains. Considering the 2020 UNAIDS target 90-90-90 for diagnosis, treatment, and viral suppression of people living with HIV (PLWH), our purpose was to verify if, starting from new diagnoses, the viral suppression rate of our cohort of new PLWH satisfied the second and the third steps. METHODS This retrospective study regards all patients aged ≥15 undergoing HIV test at our clinic between January 2005 and December 2017. We evaluated the second and the third '90 UNAIDS targets and the unclaimed tests, linkage to care, retention in ART, and the viral suppression at 1 and 2 years. Logistic regression (odds ratio, 95% confidence interval) was performed. RESULTS We observed 592 new diagnoses for HIV infection: 61.4% on Italians, 38.5% on foreigners. An antiretroviral treatment was started on 78.8% of the new diagnoses (467/592) (second UNAIDS target), and a viral suppression was obtained at 2 years on 82% of PLWH who had started ART (383/467) (third UNAIDS target), namely only 64.7% of the new diagnoses instead of the hoped-for 81% of the UNAIDS target. Logistic regressions demonstrated that second and third '90 UNAIDS targets were unrelated to sex, nationality, CD4 cells count, HIV-RNA and CDC stage (p>0.05). The age class 25-50 years (OR=2.24; 95% CI = 1.06-4.37; p=0.04) achieves more likely viral suppression when compared with patients <25 years. Considering the continuum of care, 88 (15%) PLWH were lost to engagement in care (55 unclaimed tests and 33 unlinked to care), 37 didn't start ART, 51 were LFTU at 2 years. CONCLUSIONS UNAIDS goal was far to be reached. The main challenges were unreturned tests as well as the retention in ART. Rapid tests for a test-treat strategy and frequent phone communications in the first ART years could facilitate UNAIDS target achievement.

Abstract
Background and aims Late HIV diagnosis is associated with onward HIV transmission, higher morbidity, mortality and healthcare costs. In Italy, more than half of people living with HIV were diagnosed late during the last decade, with a CD4 count < 350 cells/mm3 at diagnosis. We aimed to determine the number and characteristics of people living with undiagnosed HIV infection and low CD4 counts in Italy. Methods Data on newly reported HIV diagnoses from 2012 –2014 were obtained from the national HIV surveillance system. We used the European Centre for Disease Prevention and Control HIV modelling tool to calculate the undiagnosed prevalence and yearly diagnosed fraction (YDF) in people with low CD4 count. Results The estimated annual number undiagnosed HIV infections with low CD4 count was on average 6,028 (95% confidence interval (CI): 4,954–8,043) from 2012–2014. In 2014, most of the undiagnosed people with low CD4 count were men (82.8%), a third acquired HIV through sex between men (MSM) (35.0%), and heterosexual transmission (33.4%), respectively. The prevalence of undiagnosed HIV infection was 11.3 (95% CI: 9.3–14.9) per 100,000 residents ranging from 0.7 to 20.8 between Italian regions. Nationally the prevalence rate was 280.4 (95% CI: 173.3–450.2) per 100,000 MSM, 8.3 (95% CI: 4.9–13.6) per 100,000 heterosexual men, and 3.0 (95% CI: 1.4–5.6) per 100,000 women. The YDF was highest among heterosexual women (27.1%; 95% CI: 16.9–45.2%). Conclusions These findings highlight the importance of improving efforts to identify undiagnosed HIV infections primarily among men, both MSM and heterosexual men.
