ABSTRACT
We report an outbreak of Candida auris across multiple healthcare facilities in Israel. For the period of May 2014-May 2022, a total of 209 patients with C. auris infection or colonization were identified. The C. auris incidence rate increased 30-fold in 2021 (p = 0.00015), corresponding in time with surges of COVID-19-related hospitalization. Multilocus sequence typing revealed hospital-level outbreaks with distinct clones. A clade III clone, imported into Israel in 2016, accounted for 48.8% of typed isolates after January 2021 and was more frequently resistant to fluconazole (100% vs. 63%; p = 0.00017) and voriconazole (74% vs. 5.2%; p<0.0001) than were non-clade III isolates. A total of 23% of patients had COVID-19, and 78% received mechanical ventilation. At the hospital level, outbreaks initially involved mechanically ventilated patients in specialized COVID-19 units and then spread sequentially to ventilated non-COVID-19 patients and nonventilated patients.

In a multicenter, nationwide, retrospective study of patients hospitalized with spotted fever group rickettsiosis in Israel during 2010-2019, we identified 42 cases, of which 36 were autochthonous. The most prevalent species was the Rickettsia conorii Israeli tick typhus strain (n = 33, 79%); infection with this species necessitated intensive care for 52% of patients and was associated with a 30% fatality rate. A history of tick bite was rare, found for only 5% of patients; eschar was found in 12%; and leukocytosis was more common than leukopenia. Most (72%) patients resided along the Mediterranean shoreline. For 3 patients, a new Rickettsia variant was identified and had been acquired in eastern, mountainous parts of Israel. One patient had prolonged fever before admission and clinical signs resembling tickborne lymphadenopathy. Our findings suggest that a broad range of Rickettsia species cause spotted fever group rickettsiosis in Israel.

We report a series of 5 case-patients who had Israeli spotted fever, of whom 2 had purpura fulminans and died. Four case-patients were given a diagnosis on the basis of PCR of skin biopsy specimens 3-4 days after treatment with doxycycline; 1 case-patient was given a diagnosis on the basis of seroconversion. Rickettsia spp. from the 2 case-patients who died were sequenced and identified as Rickettsia conorii subsp. israelensis. Purpura fulminans has been described in association with R. rickettsii and R. indica, but rarely with R. conorii subsp. israelensis.

Candida auris and C. haemulonii are closely related, multidrug-resistant emerging fungal pathogens that are not readily distinguishable with phenotypic assays. We studied C. auris and C. haemulonii clinical isolates from 2 hospitals in central Israel. C. auris was isolated in 5 patients with nosocomial bloodstream infection, and C. haemulonii was found as a colonizer of leg wounds at a peripheral vascular disease clinic. Liberal use of topical miconazole and close contact among patients were implicated in C. haemulonii transmission. C. auris exhibited higher thermotolerance, virulence in a mouse infection model, and ATP-dependent drug efflux activity than C. haemulonii. Comparison of ribosomal DNA sequences found that C. auris strains from Israel were phylogenetically distinct from isolates from East Asia, South Africa and Kuwait, whereas C. haemulonii strains from different countries were closely interrelated. Our findings highlight the pathogenicity of C. auris and underscore the need to limit its spread.

BACKGROUND: Rhabdomyolysis is an uncommon complication of hyponatremia, reported previously only in case reports and small retrospective studies, and its underlying mechanism is controversial. Some studies support the hypothesis that the rapid correction of hyponatremia is responsible for rhabdomyolysis, whereas others emphasize the severity of the hyponatremia as a predisposing factor for rhabdomyolysis. OBJECTIVES: To test the association between hyponatremia and rhabdomyolysis and to demonstrate a causal association. METHODS: Hyponatremia was induced by administration of water and desmopressin acetate in rats during 3 days, followed by its rapid correction, using animal models established for the evaluation of central pontine myelinolysis. The plasma creatine phosphokinase levels, a marker for rhabdomyolysis, were monitored, and hematoxylin and eosin sections of the quadriceps and gastrocnemius muscles were evaluated for signs of rhabdomyolysis. RESULTS: The induction of hyponatremia and its correction were accompanied by the previously reported neurological sequelae, including signs of central pontine myelinolysis. However, no increase in plasma creatine phosphokinase levels was found, and histopathological examination of the quadriceps and gastrocnemius muscles revealed no sign of rhabdomyolysis. CONCLUSIONS: The present study, which is the first to test the association between hyponatremia and rhabdomyolysis in an animal model, does not support any causal association between hyponatremia and rhabdomyolysis. Thus, other factors might be necessary for an association between hyponatremia and rhabdomyolysis, such as genetic factors or convulsions that are known to be associated with both hyponatremia and rhabdomyolysis. Further research in this important physiologic and clinical question is needed.

BACKGROUND AND OBJECTIVES: In most areas of the world, urine bacteria have high resistance rates to third-generation cephalosporins, and it is unclear if it is safe to treat stable patients with bacteremic urinary tract infections (UTI) with those antibiotics. There are recommendations that empiric therapy for a suspected UTI should include only antibiotics with resistance rates less than 10%. MATERIALS AND METHODS: In this historical observational single center study, we selected 180 stable internal medicine patients hospitalized between January 2019 and December 2021, with identical bacteria isolated from blood and urine cultures. Charts were reviewed to determine if deaths and readmissions up to 30 days after discharge were due to bacterial resistance to initial antibiotic therapy (BRIAT). RESULTS: The patient's median age was 82 years (1st-3rd quartiles, 73-87 years). A total of 54.4% were female. There were 125 patients treated with ceftriaxone. A total of 38 (30.3%) had BRIAT. Four patients died, but none were because of a delay in appropriate treatment. The median days of hospitalization for all patients was 7 days, and 9 days versus 6 days in those with and without BRIAT. There were no re-hospitalizations for a UTI in patients with BRIAT. CONCLUSIONS: We conclude that, despite high resistance rates, empiric ceftriaxone in stable hospitalized patients with a bacteremic UTI is safe. There was no urosepsis-related mortality during the hospitalization or on follow-up. The treatment of all patients with wider-spectrum antibiotics might have decreased the median hospital stay by only one day. The potential effect would be even lower if all patients with a suspected systemic UTI were treated with wide-spectrum antibiotics, because some patients do not have an infection of the urinary tract. A reassessment of the recommendation that empiric therapy for a suspected systemic urinary tract infection should include only wider-spectrum antibiotics is warranted.
ABSTRACT
Background: Q fever has significant consequences for patients with persistent localized infection. A combination of doxycycline with hydroxychloroquine, for at least 18-24 months, is the first-line therapy. The use of serology as a prognostic marker during therapy is controversial. Methods: A retrospective, observational cohort study in two outpatient clinics in northern Israel. All adults with persistent Q fever (2015-2021) were included in the study. Clinical failure was defined as relapse or death related to Q fever after end of treatment (EOT). Serological cure was defined as phase 1 IgG ≤800 or a four-fold decrease at EOT. Results: Twenty-two patients were included in the study, with a median follow up of 40 months (IQR = 28.5-63.5), and median treatment duration of 28.5 months (IQR = 21.8-50.5). Clinical cure occurred in 18 patients (82%), serological cure in 10 (45%). Phase 1 IgG at presentation was significantly higher in the clinical failure group (median 9600 vs. 3200 in the clinical cure group, p = 0.019), and at 6-12 months after EOT (median 6400 vs. 800 respectively, p = 0.03). Phase 1 IgG levels at 1 year and EOT were similar in both groups. Positive phase 2 IgM after one year of therapy correlated with clinical failure (p = 0.038), but not at EOT or after EOT. Conclusion: Phase 1 IgG levels at presentation, phase 2 IgM at 1 year, and Phase 1 IgG 6-12 months after EOT were associated with clinical failure in patients with persistent Q fever.

Infection might be associated with increased risk of venous thromboembolism (VTE) and arterial thrombosis. Specific hypotheses have been raised regarding the procoagulant response induced by acute cytomegalovirus (CMV) infection. Accordingly, we investigated the 6-month incidence of VTE and/or arterial thrombosis in patients that had been tested positive for CMV-IgM antibodies in a large health maintenance organization. Logistic regression analysis was used to identify independent risk factors for VTE and arterial thrombosis. Among 90,515 patients eligible for the VTE analysis and 90,805 patients eligible for the arterial thrombosis analysis, 6,205 (6.9%) and 6,222 (6.9%) patients were tested positive for CMV-IgM antibodies, respectively. During 6 months of follow-up from index date, the incidence rates per 1,000 capita of VTE among CMV-IgM seropositive and CMV-IgM seronegative patients were 3.06 (19 patients) and 1.36 (115 patients), respectively (odds ratio (OR) 2.25; 95% confidence intervals (95% CI) 1.38-3.66; p = 0.003). CMV-IgM seropositivity was independently associated with VTE appearance (OR 2.49; 95% CI 1.53-4.06; p < 0.0001) following adjustment for age, sex, and other confounders. The incidence rates per 1,000 capita of arterial thrombosis among CMV-IgM seropositive and CMV-IgM seronegative patients were 1.12 (7 patients) and 1.06 (90 patients), respectively (OR 1.06; 95% CI 0.49-2.28; p = 0.840). CMV-IgM seropositivity was not associated with arterial thrombosis. We conclude that acute CMV infection might be associated with an increased short-term VTE risk. To the best of our knowledge, this is the largest study ever to confirm this association.

BACKGROUND: The role of bacterial and viral co-infection in the current COVID-19 pandemic remains elusive. The aim of this study was to describe the rates and features of co-infection on admission of COVID-19 patients, based on molecular and routine laboratory methods. METHODS: A retrospective study of COVID-19 and non-COVID-19 patients undergoing Biofire®, FilmArray® Pneumonia Panel, bioMérieux, and routine cultures during the first 3 days from admission, between June 2019 and March 2021. RESULTS: FilmArray tests were performed in 115 COVID-19 and in 61 non-COVID-19 patients. Most (>99%) COVID-19 patients had moderate-critical illness, 37% required mechanical ventilation. Sputa and endotracheal aspirates were the main samples analyzed. Positive FilmArray tests were found in 60% (70/116) of the tests amongst COVID-19 patients and 62.5% (40/64) amongst non-COVID-19 patients. All 70 cases were positive for bacterial targets, while one concomitant virus (Rhinovirus/Enterovirus) and one Legionella spp. were detected. The most common bacterial targets were Haemophilus influenzae (36%), Staphylococcus aureus (23%), Streptococcus pneumoniae (10%) and Enterobacter cloacae (10%). Correlation between FilmArray and cultures was found in 81% and 44% of negative and positive FA tests, respectively. Positive FilmArray results typically (81%) triggered the administration of antibiotic therapy and negative results resulted in antimicrobials to be withheld in 56% of cases and stopped in 8%. Bacterial cultures of COVID-19 patients were positive in 30/88 (34%) of cases. CONCLUSIONS: Bacterial co-infection is common amongst moderate-critical COVID-19 patients on admission while viral and atypical bacteria were exceedingly rare. Positive FilmArray results could trigger potentially unnecessary antibiotic treatment.KEY POINTWe found high rates of on-admission bacterial co-infection amongst hospitalized moderate to severe COVID-19 patients. Molecular tests (Biofire, FilmArray) and routine microbiological tests revealed 60% and 34% bacterial co-infection, respectively, while viral and fungal co-infections were rare.

BACKGROUND: Accumulated data in the past years suggest that vitamin D deficiency has an adverse effect on cardiovascular (CVD) health and that its prevalence is significantly higher among patients with CVD risk factors, contributing to the pathogenesis of CVD. MATERIALS AND METHODS: This is a cross-sectional analysis of a relatively large database derived from a health care maintenance organization. The population consisted of individuals 18 years and older who had undergone blood tests for vitamin D levels for any reason during 2001-2008. RESULTS: The study population consisted of 34,874 individuals: 26,699 (76·6%) were women at a mean ± SD age of 55 ± 15 and 8175 men (23·4%) aged 55 ± 17. The mean ± SD vitamin D level was 23·2 ± 10·1 and 22·7 ± 9·9 for men and women, respectively. The prevalence of vitamin D deficiency or insufficiency (vitamin D levels < 30 ng mL(-1)) for the entire study population was surprisingly high for men and women (79·2% and 77·5%, respectively). This remained consistent with only little variation when stratified by age. The group with vitamin D < 15 ng mL(-1) vs. the group with vitamin D levels ≥ 30 ng mL(-1) demonstrated a significant (P < 0·031) age-adjusted odds ratios for the presence of hypertension, diabetes mellitus, dyslipidemia, obesity and peripheral vascular disease for women (OR = 1·19; 1·65; 1·13; 2·28; 1·85, respectively), and the presence of all the above except hypertension in men (OR = 1·51; 1·28; 2·06; 1·73, respectively). CONCLUSIONS: Vitamin D deficiency is associated with CVD and other risk factors in this Israeli study population. The prevalence of the deficiency in Israel is similar to the prevalence found in less sunny regions.

Background: The clonal repertoire of community-associated Methicillin-resistant Staphylococcus aureus (CA-MRSA) strains appear to differ between hospitals and geographic locations. We aimed to study the molecular epidemiology of MRSA infections in our regional hospital in Israel. Methods: A retrospective analysis of MRSA isolates from hospitalized patients, which underwent spa typing between 2012 and 2019. Mainly, MRSA-bloodstream isolates were typed. Isolates were grouped into healthcare-associated (HcA) or community-associated (CA). HcA were further divided into hospital-related or long-term care facility- (LTCF-) related. Several representatives underwent SCCmec typing. Results: We analyzed 166 clinical MRSA isolates: 115 (70%) bloodstream, 42 (25%) wounds/abscesses, and 9 (5%) screening isolates. 145 (87%) were HcA, and 21 (13%) were CA. Common (72%) spa types were t002, t032, t008, t001, and t065. Eighty (55%) isolates were attributed to LTCFs and 65 isolates to our hospital, both showing similar spa types distribution. The most prevalent spa type among patients with HcA infection was t002 (50 isolates, 32%), followed by t032, t065, t578, t008, and t001. Most (88/115, 77%) bloodstream infections (BSIs) were HcA, typically occurring in the same facility in which the infection was acquired. In 27 cases (23%), the BSI developed in the community setting, and in half of these cases, a previous healthcare system exposure was evident. Conclusions: The MRSA clonal population in this longitudinal study was stable and consisted mainly of molecular lineages widespread in Europe. SCCmec-IV strains play a major role in causing MRSA infections in the healthcare settings, especially in LTCFs. Community-acquired MRSA BSIs without any previous healthcare exposure are still relatively rare.

INTRODUCTION: Acute Q fever is endemic in Israel, yet the clinical and laboratory picture is poorly defined. METHODS: A retrospective study reviewing the medical records of acute Q fever patients, conducted in a single hospital in the Sharon district, Israel. Serum samples from suspected cases were preliminary tested by a qualitative enzyme immunoassay (EIA). Confirmatory testing at the reference laboratory used an indirect immunofluorescence assay (IFA). Positive cases were defined as fever with at least one other symptom and accepted laboratory criteria such as a single-phase II immunoglobulin G (IgG) antibody titer ≥1:200. Cases not fulfilling these criteria and in which acute Q fever was excluded, served as a control group. RESULTS: Between January 2012 and May 2018, 484 patients tested positive. After confirmatory testing, 65 (13.4%) were positive for acute Q fever (with requisite clinical picture), 171 (35.3%) were definitely not infected, the remaining 248 were excluded because of past/chronic/undetermined infection. The average age was 58 years and 66% were males. Most resided in urban areas with rare animal exposure. Pneumonia was seen in 57% of cases and a combination with headache/hepatitis was highly suggestive of acute Q fever diagnosis. Syncope/presyncope, fall and arthritis were more common in acute Q fever cases. Laboratory indexes were similar to the control group, except for erythrocyte sedimentation rate (ESR) which was more common and higher in the study group. CONCLUSION: Acute Q fever in the Sharon district could be better diagnosed by using a syndromic approach in combination with improved rapid diagnostic testing.

BACKGROUND: The role of bacterial co-infection and superinfection among critically ill COVID-19 patients remains unclear. The aim of this study was to assess the rates and characteristics of pulmonary infections, and associated outcomes of ventilated patients in our facility. METHODS: This was a retrospective study of ventilated COVID-19 patients between March 2020 and March 2021 that underwent BioFire®, FilmArray® Pneumonia Panel, testing. Community-acquired pneumonia (CAP) was defined when identified during the first 72 h of hospitalization, and ventilator-associated pneumonia (VAP) when later. RESULTS: 148 FilmArray tests were obtained from 93 patients. With FilmArray, 17% of patients had CAP (16/93) and 68% had VAP (64/93). Patients with VAP were older than those with CAP or those with no infection (68.5 vs. 57-59 years), had longer length of stay and higher mortality (51% vs. 10%). The most commonly identified FilmArray target organisms were H. influenzae, S. pneumoniae, M. catarrhalis and E. cloacae for CAP and P. aeruginosa and S. aureus for VAP. FilmArray tests had high negative predictive values (99.6%) and lower positive predictive values (~60%). CONCLUSIONS: We found high rates of both CAP and VAP among the critically ill, caused by the typical and expected organisms for both conditions. VAP diagnosis was associated with poor patient outcomes.
ABSTRACT
BACKGROUND AND OBJECTIVES: Coronavirus disease 2019 (COVID-19) is associated with higher morbidity and mortality in patients on maintenance hemodialysis. Patients on dialysis tend to have a reduced immune response to infection or vaccination. We aimed to assess, for the first time to the best of our knowledge, the humoral response following vaccination with the BNT162b2 vaccine in patients on maintenance hemodialysis and the factors associated with it. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The study included 56 patients on maintenance hemodialysis (dialysis group) and a control group composed of 95 health care workers. All participants had received two doses of the BNT162b2 (Pfizer-BioNTech) vaccine. The serology testing was done using Quant II IgG anti-Spike severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) assay by Abbott a median of 30 days after receipt of the second dose of the vaccine. RESULTS: All subjects in the control group developed an antibody response compared with 96% (54 of 56) positive responders in the dialysis group. The IgG levels in the dialysis group (median, 2900; interquartile range, 1128-5651) were significantly lower than in the control group (median, 7401; interquartile range, 3687-15,471). A Mann-Whitney U test indicated that this difference was statistically significant (U=1238; P<0.001). There was a significant inverse correlation of age and IgG levels in both groups. The odds of being in the lower quartile were significantly higher for older individuals (odds ratio, 1.11 per year of age; 95% confidence interval, 1.08 to 1.20; P=0.004) and for the dialysis group compared with the control group (odds ratio, 2.7; 95% confidence interval, 1.13 to 7.51; P=0.05). Within the dialysis group, older age and lower lymphocyte count were associated with antibody response in the lower quartile (odds ratio, 1.22 per 1-year older; 95% confidence interval, 1.13 to 1.68; P=0.03 and odds ratio, 0.83 per 10-e3/µl-higher lymphocyte count; 95% confidence interval, 0.58 to 0.97; P=0.05). CONCLUSIONS: Although most patients on maintenance hemodialysis developed a substantial humoral response following the BNT162b2 vaccine, it was significantly lower than controls. Age was an important factor in the humoral response, regardless of chronic medical conditions.

INTRODUCTION: The epidemiology, clinical features and outcomes of hospitalized adult patients with Influenza A (FluA), Influenza B (FluB) and Respiratory Syncytial Virus (RSV) have not been thoroughly compared. The aim of this study was to describe the differences between these viruses during 3 winter seasons. METHODS: A retrospective observational study was conducted consisting of all the polymerase chain reaction (PCR)-based diagnoses of FluA, FluB and RSV among adults during 2015-2018, in one regional hospital. Epidemiology, clinical symptoms and outcome-related data were comparatively analyzed. RESULTS: Between November 2015 and April 2018, 759 patients were diagnosed with FluA, FluB or RSV. Study cohort included 539 adult patients (306 FluA, 148 FluB and 85 RSV). FluB was predominant during the winter of 2017-18. RSV caused 15.7% of hospitalizations with diagnosed viral infection and in comparison to influenza, had distinct epidemiological, clinical features and outcomes, including older age (74.2 vs 66.2, p = 0.001) and higher rates of co-morbidities; complications including bacterial pneumonia (31 vs 18%, p = 0.02), mechanical ventilation (20 vs 7%, p = 0.001), and viral-related death (13 vs 6.6%, p = 0.04). FluA and FluB had similar epidemiology, clinical symptoms and outcomes, but vaccinated patients were less prone to be hospitalized with FluB as compared with FluA (3 vs 14%, p = 0.001). Paroxysmal atrial fibrillation and falls were common (8.7 and 8.5% respectively). CONCLUSIONS: FluA and FluB had similar epidemiological, clinical features and contributed equally to hospitalization burden and complications. RSV had a major impact on hospitalizations, occurring among the more elderly and sick populations and causing significantly worse outcomes, when compared to influenza patients. Vaccination appeared as a protective factor against hospitalizations with FluB as compared with FluA.

We describe a case report of a 56-year-old male with undiagnosed multiple myeloma who had severe sepsis associated with pneumonia, meningitis, polyarthritis, and osteomyelitis related to invasive "Haemophilus quentini" infection. The genus was misidentified as H. influenzae by the common bacterial identification systems including newly introduced syndromic PCR-based methods. We review the epidemiological, clinical, and laboratory aspects of this rare, cryptic species of Haemophilus.

BACKGROUND: Invasive group A streptococcal (iGAS) infection in the peripartum setting is a rare but devastating disease occasionally occurring as a health care-associated infection (HAI). Current guidelines suggest enhanced surveillance and streptococcal isolate storage after a single case of iGAS, as well as a full epidemiological investigation that includes screening health care workers (HCWs) from several sites after 2 cases. Current guidelines do not recommend routine screening of household members of a patient with iGAS. METHODS: We conducted studies of 3 patients with iGAS puerperal sepsis and related epidemiologic and molecular investigations. RESULTS: Identical GAS emm gene types were found in pharyngeal cultures of 3 asymptomatic spouses of patients with iGAS puerperal sepsis. HCWs screened negative for GAS, and emm typing indicated that other iGAS cases from this hospital were sporadic and not related to the puerperal cases. CONCLUSIONS: The concurrent presence of the same emm type in a household member practically excludes the option of an inadvertent HAI or facility outbreak. Hence, we suggest that screening close family members for asymptomatic GAS carriage should be performed early as a part of infection prevention measures, as doing so would have significant utility in saving time and resources related to a full epidemiological inquiry.

To study the clinical presentation of Chronic Schistosomiasis (CS) in immigrants from East Africa to Israel and the tests that were useful in confirming the diagnosis.A retrospective study of all medical notes pertaining to hospitalized patients who were immigrants from East Africa with a pathological or microscopic confirmation of CS. Literature review was also conducted focusing on diagnosis of schistosomiasis among immigrants from endemic countries.We identified 32 suspected and 11 confirmed cases of CS. Most of the patients (82%) presented with gastrointestinal symptoms. Sensitivity of stool smear, serology and tissue diagnosis (by histopathology or microscopy) were 14%, 100%, 89%, respectively. Patients have undergone extensive diagnostic evaluation with long hospitalization stays (median 10 days, range 4 to 33 days).CS has multiple presentations and is seen in Israel among refugees from Eritrea and Sudan. Most of the manifestations are gastrointestinal, suggestive of infection with Schistosoma mansoni (S. mansoni). Standard diagnostic techniques used in endemic countries, such as microscopy for ova and parasites were unhelpful, necessitating more advanced procedures like colonoscopic or liver biopsy. We propose a diagnostic algorithm for CS in this patient population in order to make an accurate diagnosis and avoid unnecessary invasive procedures.

An unusual case of infective endocarditis and concurrent multiple liver abscesses both caused by Streptococcus anginosus in a splenectomised patient is reported. The microorganism is a very rare cause of endocarditis and its presentation with multiple liver abscesses is highly unusual.
