Despite the low prevalence of HIV-1 in Israel, continuous waves of immigration may have impacted the local epidemic. We characterized all people diagnosed with HIV-1 in Israel in 2010–2018. The demographics and clinical data of all individuals (n = 3639) newly diagnosed with HIV-1 were retrieved. Subtypes, transmitted drug-resistance mutations (TDRM), and phylogenetic relations, were determined in >50% of them. In 39.1%, HIV-1 transmission was through heterosexual contact; 34.3% were men who have sex with men (MSM); and 10.4% were people who inject drugs. Many (>65%) were immigrants. Israeli-born individuals were mostly (78.3%) MSM, whereas only 9% of those born in Sub-Saharan Africa (SSA), Eastern Europe and Central Asia (EEU/CA), were MSM. The proportion of individuals from SSA decreased through the years 2010–2018 (21.1% in 2010–2012; 16.8% in 2016–2018) whereas those from EEU/CA increased significantly (21% in 2010–2012; 27.8% in 2016–2018, p < 0.001). TDRM were identified in 12.1%; 3.7, 3.3 and 6.6% had protease inhibitors (PI), nucleotide reverse transcriptase inhibitors (NRTI), and non-nucleoside reverse transcriptase inhibitors (NNRTI) TDRM, respectively, with the overall proportion remaining stable in the studied years. None had integrase TDRM. Subtype B was present in 43.9%, subtype A in 25.2% (A6 in 22.8 and A1 in 2.4%) and subtype C in 17.1% of individuals. Most MSM had subtype B. Subtype C carriers formed small clusters (with one unexpected MSM cluster), A1 formed a cluster mainly of locally-born patients with NNRTI mutations, and A6 formed a looser cluster of individuals mainly from EEU. Israelis, <50 years old, carrying A1, had the highest risk for having TDRM. In conclusion, an increase in immigrants from EEU/CA and a decrease in those from SSA characterized the HIV-1 epidemic in 2010–2018. Baseline resistance testing should still be recommended to identify TDRM, and improve surveillance and care.

The aim of this study was to describe the predictors and outcomes of infection with extended-spectrum beta-lactamase (ESBL)-producing bacteria in patients with an acute diabetic foot infection (DFI). The records of patients admitted with acute DFI to a large tertiary hospital during the years 2014-2018 were reviewed. Demographic, clinical, and laboratory data were collected, as well as outcomes regarding amputations and mortality. Only cultures obtained during the first 2 weeks following admission were considered. Cultures were available for 493 patients; 121 (24.5%) included bacteria suspected of being ESBL producers. Patients infected with ESBL-producing bacteria were older, more likely to have peripheral vascular disease (PVD), and had higher SINBAD and Wagner scores upon admission. They were also more likely to have been hospitalized in the recent 6 months. Major amputations were more prevalent in patients with versus without an ESBL-producing bacterial infection (30.6% vs 19.4%; P = 0.010), yet overall amputations and mortality rates were similar. ESBL-producing bacteria are common pathogens in DFI, more prevalent in older patients with PVD, advanced ulcers, and recent hospitalization. They are associated with higher rates of major amputation. These considerations may support the choice of empirical antibiotic therapy in patients admitted with an acute DFI.
Despite the progress in contemporary antiretroviral therapy (ART) and the continuous changes in treatment guidelines, virological failure (VF) is still an ongoing concern. The goal of this study was to assess factors related to VF after first-line ART. A longitudinal cohort retrospective study of individuals on first-line ART diagnosed with HIV-1 in 2010–2018 and followed-up for a median of two years was conducted. Demographics, baseline and longitudinal CD4 counts, treatment regimens, adherence and VF were recorded. The Cox proportional hazards regression and mixed models were used. A cohort of 1130 patients were included. Overall, 80% were males and 62% were Israeli-born individuals. Compared to individuals diagnosed in 2010–2014, when treatment was initiated according to CD4 levels, those diagnosed in 2015–2018 were older and had lower baseline CD4 counts. VF was recorded in 66 (5.8%) patients. Diagnosis with CD4 <200 cells/mmᶟ with AIDS-defining conditions (HR = 2.75, 95%CI:1.52–4.97, p < 0.001) and non-integrase strand transfer inhibitor regimens (non-INSTI, HR = 1.80, 95%CI:1.01–3.24, p = 0.047) increased VF risk. No impact of baseline resistance was observed. We concluded that the early detection of HIV-1 infection and usage of INSTI-based regimens are recommended to reduce VF.

Objectives. Prevalence of hypertension has not been studied in the Ethiopian HIV-infected population, which represents 60% of the patients in our AIDS unit. Our aim was to identify risk factors and characterize the prevalence of hypertension in the population monitored at our unit. Methods. A retrospective chart review categorized subjects according to their blood pressure levels. Hypertension prevalence was determined and stratified according to variables perceived to contribute to elevated blood pressure. Results. The prevalence of hypertension in our study population was significantly higher compared to the general population (53% versus 20%, ) and was associated with known risk factors and not with patients’ viral load and CD4 levels. Ethiopian HIV-infected adults had a prominently higher rate of blood pressure rise over time as compared to non-Ethiopians (). Conclusions. The high prevalence of hypertension in this cohort and the rapid increase in blood pressure in Ethiopians are alarming. We could not attribute high prevalence to HIV-related factors and we presume it is part of the metabolic syndrome. The lifelong cardiovascular risk associated with HIV infection mandates hypertension screening and close monitoring in this population.
Introduction: Although women comprise 33% of the HIV-1-carriers in Israel, they have not previously been considered a risk group requiring special attention. Immigration waves from countries in Africa and in East Europe may have changed the local landscape of women diagnosed with HIV-1. Here, we aimed to assess viral and demographic characteristics of HIV-1-positive women identified in Israel between 2010 and 2018. Methods: All > 16 year-old, HIV-1-infected women, diagnosed in Israel in 2010–2018, (n = 763) registered in the National HIV reference laboratory were included in this cross-sectional study. Demographic and clinical characteristics were extracted from the database. Viral subtypes and transmitted drug resistance mutations (TDRM) were determined in 337 (44.2%) randomly selected samples collected from treatment-naive women. Results: Median age at diagnosis was 38 years. Most (73.3%) women were immigrants from the former Soviet Union (FSU) (41.2%, 314) or sub-Saharan Africa (SSA) (32.2%, 246) and carried subtype A (79.7%) or C (90.3%), respectively. Only 11.4% (87) were Israeli-born women. Over the years, the prevalence of women from SSA decreased while that of women from FSU increased significantly (p < 0.001). The median CD4+ cell count was 263 cells/mm3, and higher (391 cells/mm3) in Israeli-born women. TDRM were identified in 10.4% of the tested samples; 1.8, 3 and 7.1% had protease inhibitors (PI), nucleotide reverse transcriptase inhibitors (NRTI) and non-nucleoside reverse transcriptase inhibitors (NNRTI) TDRM, respectively. The prevalence of women with NNRTI TDRM significantly increased from 4.9% in 2010–2012 to 13.3% in 2016–2018. Israeli-born women had the highest prevalence (16.3%) of NNRTI TDRM (p = 0.014). NRTI A62 (5.6%), NNRTI E138 and K103 (5.6 and 4.2%, respectively) were the most prominent mutated sites. Conclusions: Most HIV-1-positive women diagnosed in Israel in 2010–2018 were immigrants, with the relative ratio of FSU immigrants increasing in recent years. The high proportion of women diagnosed with resistance mutations, particularly, the yearly increase in the frequency of NNRTI mutations, support the national policy of resistance testing at baseline.
In Israel, irregular migrants (IMs) living with human immunodeficiency virus (HIV-1) that have no access to regular health insurance are provided with HIV-1-related health coverage under a public–private partnership (PPP) program initiated by the Ministry of Health in 2014. Here we characterized IMs referred to the PPP in 2019–2024 and used a linear mixed-effects model to follow up their CD4 and HIV-1 viral load (VL) counts for a median period of 16 months. Subtypes, resistance mutations and phylogenetic relationships were determined in all cases with viral failure and in selected cases with available blood remains. A total of 231 of 238 referred to the PPP initiated antiretroviral treatment (ART) with nucleoside reverse transcriptase inhibitors (NRTIs) and either non-nucleoside reverse transcriptase inhibitors (NNRTIs, 61.5%, 142/231) or protease inhibitors (PIs, 38.5%, 89/231). Irrespective of the treatment regimen, all these individuals increased their CD4 and decreased their VL trajectories over time (p < 0.001). However, mixed model analysis revealed two classes of CD4 trajectory patterns. Comparison between these two patterns revealed that Class-1 individuals started with lower initial CD4 counts compared to Class-2 individuals (median of 115 cells/mm3, IQR 70–171 compared to median of 312 cells/mm3, IQR 104–510, p < 0.001) and experienced slower recovery compared to Class-2. Most Class-1 individuals originated from Africa (78% vs. 52%, p = 0.016). Treatment failure was observed in 5.6% of all individuals receiving treatment under the program. Sequencing analysis, enabled in 23% of the treated cohort, revealed that the reverse transcriptases (RT) M184V (13%) and K103N (7.4%) were the most prevalent mutations. Conclusively, while treatment was not consistent with current recommendations for first-line therapy, the virological and immunological response of most patients was favorable and the prevalence of cases with resistance mutations was not higher than that identified in people living with HIV-1 who are covered by the national health insurance. Despite the limitations of the PPP, this program may provide a unique therapeutic opportunity for IMs with HIV-1.
