In 2019, the Israeli Ministry of Health joined the World Health Organization initiative to eliminate hepatitis C virus (HCV) (1). The national elimination program included HCV testing among 6 high-risk [...]

Background/Objectives: Mycoplasma genitalium (MG) infections and antibiotic resistance are increasing in prevalence while treatment options are limited. Limited data exist regarding MG resistance in Israel. Our aim was to study the prevalence of MG resistance in a sexually transmitted infection (STI) clinic in Israel. Methods: We performed a single-center retrospective study among patients attending an STI clinic during 2019–2020. MG isolates were tested to detect their resistance to azithromycin and fluoroquinolones (FQs) using commercial kits (Allplex™ MG & AziR Assay, Allplex™ MG & MoxiR Assay). We collected patient data regarding the risk factors for STIs and resistance. A multivariate logistic regression model was used to identify the risk factors for resistance. Results: Of the 142 patients who tested positive for MG, 50 (35.2%) and 22 (15.5%) had resistant mutations to azithromycin and FQ, respectively, and 13 (9.2%) showed resistance to both agents. In a multivariate logistic regression model, men who have sex with men (RR 7.01 95% CI 3.00–16.33) and past STIs (RR 2.33 95% CI 1.01–5.34) were independent risk factors for azithromycin resistance. Conclusions: We found a high prevalence of azithromycin resistance and, to a lesser degree, FQ resistance. These findings may help design the treatment guidelines and support routine resistance testing in high-risk populations. [ABSTRACT FROM AUTHOR]

Aims To outline the demographic, clinical, laboratory characteristics, and treatment outcomes of tuberculosis (TB) patients who used substances. Methods This retrospective cohort study compared 50 TB patients who used substances with a matched random sample of 100 TB patients who did not use substances between 2007 and 2017. Treatment failure was defined as a sputum smear or culture that tested positive after 5 months of treatment, loss to follow-up, unevaluated patients, or death. Results TB patients who used substances were typically younger, experienced homelessness, smokers, and had fewer chronic diseases than those who did not use substances. They also were hospitalized for longer periods, their treatment durations were longer, had higher rates of multidrug resistant strains, increased rates of treatment failure, and higher mortality. Individuals whose treatment failed predominantly originated from the former Soviet Union, experienced homelessness, and had chronic diseases compared with those whose treatment was successful. In the multivariate analysis, homelessness [odds ratios (OR) = 6.7], chronic diseases (OR = 12.4), and substance use (OR = 4.0) were predictors of treatment failures. Conclusions TB patients who used substances were more likely to have treatment failure. Targeted interventions, including early diagnosis and enhanced support during treatment, are essential to achieve treatment success in this vulnerable population, in addition to TB-alcohol/drug collaborative activities.

During a national measles outbreak in 2018–2019, the Tel Aviv District suffered a major upsurge of cases, with 413 patients reported. Among them, 100 (24%) were <1 year, 92 (22%) patients were aged 12 months to 4 years, 47 (11%) were 5–18 years, 169 (41%) were 19–60 years, and 5 (1%) patients were older than 61 years (born before 1957). Among all cases, 230 (56%) were part of the Ultra-Orthodox Jewish community, 55 (13%) were among undocumented African immigrants. Despite high vaccination coverage, sustained measles transmission occurred, due in part to importations and numerous exposures in medical settings by a susceptible birth cohort. The Ultra-Orthodox Jewish community was particularly afflicted due to its condense population, high birth rates, and multiple exposures in crowded religious settings. This outbreak demonstrates the necessity of addressing immunity gaps as well optimal healthcare planning in order to prevent future outbreaks. [ABSTRACT FROM AUTHOR]

Men who have sex with men (MSM) and purchase sex (MPS) are a sub-group potentially at high risk for acquiring and transmitting sexually transmitted infections (STIs). This is a hard-to-reach population resulting in a scarcity of studies covering the issue. This cross-sectional study aimed to assess the association between purchasing sex and high-risk behaviors related to HIV/STI transmission and appraise the STI prevalence among MSM. All MSM who attended the STI clinic in Tel Aviv between 2003 and 2010 were included. Demographics, behavioral, clinical, and laboratory data were compared between MPS and non-MPS to identify high-risk sexual behaviors and STI prevalence associated with purchasing sex. Of the first visits of 2694 MSM who attended the STI clinic during the study period, 151 (5.6%) paid for sex. MPS were more commonly older and married than non-MPS. MPS were more likely to engage in behaviors associated with high risk for HIV/STI transmission, including infrequent condom use during anal sex, substance use during sex, and selling sex themselves. MPS had a higher STI prevalence than non-MPS, although this was not statistically significant (p = 0.05). These findings highlight the need to establish culturally tailored interventions for MPS addressing the potential risks associated with purchasing sex. [ABSTRACT FROM AUTHOR]

Background Highly active antiretroviral therapy (HAART) has changed life-expectancy and mortality trends among people living with HIV/AIDS (PLWHA) since 1996. This retrospective cohort study aimed to assess the mortality epidemiology of PLWHA in Israel and analyze the causes of death. Methods This cohort study included all adult Israeli-citizens PLWHA between 1985 and 2010 and crossed matched with the Civil Registry to identify those who died. Death certificates were classified into AIDS or non-AIDS deaths related-causes. Standardized mortality-ratio (SMR) represented mortality excess. Results Of all 5140 PLWHA who were followed-up for 36 955 person-years, 1066 (20.7%) died. The ratio of AIDS-related deaths to non-AIDS related deaths reduced from 1.2:1 before 1996 to 0.6:1 after 1997, and case-fatality rates reduced from 12.0 to 0.9%, respectively (P < 0.001). SMR were 3.0 (95% CI: 2.3-3.5) for males and 3.9 (95% CI: 3.3-4.5) for females. Fatality cases were more likely older Israeli-born males, co-infected with tuberculosis, reported before 1996 and acquired HIV by druginjection or infected-blood products. Deaths of AIDS-related causes were common among Israeli-born gay men, while non-AIDS deaths were common among those reported after 1997 and drug users. Conclusions Death rates declined since HAART introduction. Yet, SMR remained high, and PLWHA infected by drug-use or blood-products have not enjoyed relative longevity. [ABSTRACT FROM AUTHOR]

This report describes an unusual surge of West Nile fever in Israel in June 2024, during which 125 cases were diagnosed, compared with 4 cases on average during June in previous years (2014-23). Of the cases, 64 (62.1%) had neuroinvasive disease and 12 (9.6%) died; the 2024 case fatality rate was not significantly elevated vs the average rate in 2014-23. The early rise could be related to a temperature increase in spring and early summer of 2024.

Between late 2023 and early 2024, two measles outbreaks occurred in Israel, each caused by importation of measles virus strains of respective B3 and D8 genotypes. In this study, we validate transmission pathways uncovered by epidemiological investigations using a rapid molecular approach, based on complete measles virus genomes. The presented findings support this rapid molecular approach in complementing conventional contact tracing and highlight its potential for informing public health interventions.
