The objectives of our study were to determine the mortality rates, causes, and risk factors of people living with HIV in the modern antiretroviral therapy era, in a major HIV center in Israel. We retrospectively collected data from 1547 patients treated during 2001–2021. We used the Shapiro–Wilk test, Fisher’s exact test, Student’s t test, and chi-square to compare between patients who died and those who did not, and between patients who died from AIDS-related and non-AIDS-related causes. In total, 206 (13.3%) patients died. The causes of death were AIDS-defining diseases (33.5%), cardiovascular diseases (21.8%), non-AIDS infections (16%), and hepatic disorders (7%). The annual mortality rate was 1.31 ± 0.3%. Despite an increase in age (35 ± 13.2 in 2001, 49 ± 13.6 years in 2021; p < 0.001), the mortality rate decreased (2.12% during 2005–2008, 0.71% during 2018–2021; p = 0.0001). AIDS-defining diseases caused 75% of deaths during 2001–2002, and only 25% during 2019–2021. The proportion of cardiovascular deaths increased (8.3% in 2001–2003, 33.3% in 2019–2021; p < 0.001). Low CD4 and high viral load at diagnosis, male gender, non-MSM HIV acquisition (heterosexual transmission and people who inject drugs), and inability to achieve viral suppression because of non-compliance were risk factors for mortality. Mortality rates decreased during 2001–2021; however, the proportion of non-AIDS deaths increased. Early cardiovascular comorbidity screening and targeted adherence interventions in non-MSM populations and in patients with low CD4 are needed.

Introduction – Gender influences the presentation and progression of various diseases. Studies regarding the impact of gender on the course and outcome of HIV demonstrate conflicting data. Studies may be biased due to socioeconomic status differences between females and males and uneven gender representation, among other factors. In order to minimize the effect of non-biological elements this study cohort compares HIV males and females with similar ethnicity and social class in 2 Israeli AIDS centers. Methods –the study is a retrospective study. The cohort consists 334 females and 223 males diagnosed with HIV during the years 2000-2015. All patients were immigrants from Ethiopia who acquired HIV heterosexually and had a similar socioeconomic status. Data regarding demographics, clinical status, virological (viral load; VL), immunological (CD4) and treatment modalities were collected for each patient. Results - At the time of HIV diagnosis, males were older (43.2 ±13.2 vs. 35.4±11.95 years; p

Introduction: Variants of COVID-19 are responsible for 700 million infections and 7 million deaths worldwide. Vaccinations have high efficiency in preventing infection and secondary benefits of reducing COVID-19 hospital admissions, attenuating disease severity and duration of illness. Conflicting reports were published regarding COVID-19 among PLWH. Objective: The aim of this study was to evaluate COVID-19 morbidity, hospitalization, and the magnitude of immunological response to sequential BNT 162b2 mRNA vaccines in PLWH regarding demographic and clinical factors. Results: Our retrospective study included 784 PLWH who had at least one anti- SARS-CoV-2 antibody test between March 2021 and October 2021. Half of our patients (392) had CD4 cell counts above 500 cells/µL, 40.2% (315) had 200 < CD4 < 500 cells/µL and only 9.8% (77) had CD4 < 200 cells/µL at their last laboratory workup. The mean age was 50.2 ± 12.2 years. About 90% of our patients were given at least two doses of the BNT 162b2 Pfizer vaccines; about 60% received three doses of the vaccine. About a quarter of our patients (27.6%) had COVID-19 infection. Only six patients required hospital admission. All six patients recovered from COVID-19 infection. Titers of COVID-19 antibodies were lower for patients with CD4 cell counts of less than 200 cells/µL in the first, second, and third serological tests with statistical significance. In a multinomial logistic regression, the influence of other factors such as age, sex, and previous COVID-19 infection on first COVID-19 antibody titers was not significant. Conclusions: PLWH are responsive to COVID-19 vaccines. As was expected, patients with higher CD4 cell counts had higher titers of COVID-19 antibodies and lower hospitalization rate. Age, sex, and previous COVID-19 infection did not significantly affect antibody titers according to our study. Larger prospective studies with control groups are needed to further characterize immunologic response to COVID-19 vaccination among PLWH.

Background: Antiretroviral therapy (ART) has transformed HIV into a chronic manageable condition, yet metabolic toxicities including pancreatic enzyme alterations remain concerns. While older ART regimens have been associated with hyperamylasemia, the impact of integrase strand transfer inhibitor (INSTI)-based therapies on serum amylase levels has not been specifically examined. Purpose: This study aimed to compare longitudinal patterns of serum amylase levels between people living with HIV receiving INSTI-based versus NNRTI/PI-based ART regimens. Methods: This retrospective observational study analyzed 99 HIV-positive patients at Kaplan Medical Centre, Israel (2002–2023). Participants received either INSTI-based (n = 49) or NNRTI/PI-based (n = 50) regimens for ≥24 months. Serum amylase, viral load, CD4 counts, and metabolic parameters were measured at baseline, one year, and two years. Repeated-measures ANOVA assessed longitudinal changes. Results: NNRTI/PI-treated patients maintained significantly higher mean amylase levels throughout follow-up (baseline: 122.9 ± 42.1 U/L; two years: 129.6 ± 38.0 U/L) compared to INSTI-treated patients (baseline: 78.7 ± 32.3 U/L; two years: 68.4 ± 23.4 U/L; p < 0.0001 at all timepoints). A significant linear time-by-group interaction (p = 0.037) demonstrated divergent trajectories. No clinical pancreatitis was observed in either treatment group during the follow-up period, and all observed variations in serum amylase were biochemical and asymptomatic. While these findings are reassuring regarding acute pancreatic toxicity, the clinical significance of chronic subclinical enzyme elevations remains uncertain. Conclusion: INSTI-based antiretroviral regimens suggest a favorable pancreatic and metabolic safety profile compared with NNRTI/PI-based therapies.
