Epidemiology, Clinical Characteristics and Risk Factors for Severity of Chronic Disseminated Candidiasis in Jerusalem, Israel.

Chronic disseminated candidiasis (CDC) occurs mostly in patients with acute hematologic malignancy and its clinical manifestations derive from immune reconstitution following neutrophil recovery. The aim of this study was to describe epidemiological and clinical characteristics of CDC and define risk factors for disease severity. Demographic and clinical data were collected from medical files of patients with CDC hospitalized in two tertiary medical centers in Jerusalem between 2005 and 2020. Associations between different variables and disease severity were evaluated, as well as characterization of Candida species. The study included 35 patients. CDC incidence slightly increased during study years and the average number of involved organs and disease duration was 3 ± 1.26 and 178 ± 123 days, respectively. Candida grew in blood in less than third of cases and the most common isolated pathogen was Candida tropicalis (50%). Histopathological or microbiological workup in patients who underwent an organ biopsy demonstrated Candida in about half of the patients. Nine months after starting antifungals, 43% of the patients still didn't have resolution of organ lesions in imaging modalities. Factors associated with protracted and extensive disease were prolonged fever prior to CDC and absence of candidemia. A C- Reactive Protein (CRP) cutoff level of 7.18 mg/dL was found to predict extensive disease. In conclusion, CDC incidence is increasing and the number of involved organs is higher than previously described. Clinical factors such as fever duration prior to CDC and absence of candidemia can predict severe course of disease and assist in treatment decisions and follow-up planning.

Acute diabetic foot in post kidney transplantation patients receiving chronic immunosuppression-clinical presentation and outcomes.

AIMS: Data regarding diabetic foot ulcers in patients after solid organ transplantation, particularly kidney transplantation, are limited. Chronic immunosuppression may be associated with impaired wound healing and a higher risk of amputations. In this study, we characterised the clinical presentation and outcomes of patients after kidney transplantation admitted to the diabetic foot unit, compared to non-kidney-transplant patients. MATERIALS AND METHODS: Data on the baseline characteristics, clinical presentation, and outcomes of all patients admitted to the diabetic foot unit of a large tertiary centre between the years 2014 and 2019 were collected. The most recent admission of each patient was considered. Primary outcomes were major amputations and 1 year mortality rate. RESULTS: During the study period, 537 patients were hospitalised, 18 of them were receiving immunosuppressive therapy due to kidney transplantation. Baseline characteristics of the patients were broadly similar, except that smoking was reported by 22.0% of the non-transplant patients and by none of the post-transplant patients (p = 0.01). Post-transplant patients tended to be younger (59.4 ± 11.1 vs. 65.3 ± 12.2; p = 0.07), were more likely to have type-1 diabetes (16.7% vs. 5.2%; p = 0.07) and had lower glucose levels upon admission (9.4 ± 4.3 vs. 12.0 ± 6.4 mmol/L; p = 0.07). Overall, 30% of the patients underwent major amputation, in-patient mortality rate was 9.3%, and 1 year mortality rate was 27.2%. Rates were similar in the post-transplant versus the non-post-transplant patients (p = 0.83, 1.00, 0.59, respectively). CONCLUSIONS: Post-transplant patients did not incur worse outcomes in spite of immunosuppressive therapy. Limb salvage efforts should be pursued in these patients similar to the overall population.

Healthcare-associated Pneumocystis jirovecii Pneumonia (PJP) Infection in HIV-negative Adults: a Multicenter Study.

BACKGROUND: Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited. OBJECTIVES: To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients. METHODS: A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared. RESULTS: Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78-157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7-30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP. CONCLUSIONS: HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered.

Rituximab identified as an independent risk factor for severe PJP: A case-control study.

OBJECTIVE: Pneumocystis jirovecii pneumonia (PJP) was reported among immunosuppressed patients with deficits in cell-mediated immunity and in patients treated with immunomodulatory drugs. The aim of this study was to identify risk-factors for PJP in noninfected HIV patients. METHODS: This retrospective, test negative, case-control study was conducted in six hospitals in Israel, 2006-2016. Cases were hospitalized HIV-negative patients with pneumonia diagnosed as PJP by bronchoalveolar lavage. Controls were similar patients negative for PJP. RESULTS: Seventy-six cases and 159 controls were identified. Median age was 63.7 years, 65% males, 34% had hematological malignancies, 11% inflammatory diseases, 47% used steroids and 9% received antilymphocyte monoclonal antibodies. PJP was independently associated with antilymphocyte monoclonal antibodies (OR 11.47, CI 1.50-87.74), high-dose steroid treatment (OR 4.39, CI 1.52-12.63), lymphopenia (OR 8.13, CI 2.48-26.60), low albumin (OR 0.15, CI 0.40-0.54) and low BMI (OR 0.80, CI 0.68-0.93). CONCLUSION: In conclusion, rituximab, which is prescribed for a wide variety of malignant and inflammatory disorders, was found to be significant risk-factor for PJP. Increased awareness of possible PJP infection in this patient population is warranted.

Association of HIV and syphilis seropositivity with transit stay in urban areas among Ethiopian immigrants to Israel.

BACKGROUND: Ethiopian immigration to Israel was initiated in 1981. Most immigrants were rural dwellers who migrated first to Addis Ababa or Gondar, where they waited for eligibility status from Israel to leave Ethiopia. Soon after arriving in Israel, all immigrants were offered screening tests for human immunodeficiency virus (HIV) and syphilis. OBJECTIVES: To evaluate the association of age, gender, marital status and length of time spent in urban areas in Ethiopia with the prevalence of HIV and syphilis seropositivity. METHODS: All adult Ethiopian immigrants who arrived at the Jerusalem immigration center between 1999 and 2002 and consented to HIV and syphilis screening tests were interviewed. RESULTS: Altogether, 678 immigrants (51% females) were screened; 39 (5.8%) were seropositive for HIV and 33 (4.9%) for syphilis. The length of time the immigrants spent in Ethiopian cities before leaving for Israel was significantly associated with HIV: odds ratio (OR) 2.76, 95% confidence interval (CI) 1.13-6.71, and syphilis seropositivity OR 3.87, 95%CI 1.56-9.62. CONCLUSIONS: The length of transit time Ethiopian immigrants from rural areas spend in Ethiopian cities is significantly associated with HIV and syphilis seropositivity. Efforts should be made to shorten this time in order to reduce the risk of infection

[Assessing cardiovascular risk factors among patients living with HIV/AIDS - survey of patients treated at the Hadassah Aids Center, Hadassah Ein Kerem, Jerusalem].

BACKGROUND: It has recently become evident that people living with HIV/AIDS have an increased cardiovascular risk. The reasons leading to this risk are multifactorial. In this study, we aimed to evaluate the cardiovascular risk (CVR) among patients treated at the Hadassah AIDS Center. MATERIALS AND METHODS: We conducted a cross-sectional study. CVR was calculated using the Framingham risk score (FRS). LDL-cholesterol optimal levels were defined using National Cholesterol Education Program (NCEP) criteria. RESULTS: We analyzed data from 150 patients during 2010. Their median age was 41 years and 60% were male. Nearly 52% of our patients were immigrants from Ethiopia. Most patients (90%) were on antiretroviral therapy (ART). The median time for ART exposure was 6.5 years. Rates of hypertension (HTN) (18.5%), diabetes (5.7%) and smoking (25%) were similar to the rates found in the general Israeli population (15%, 5.7% and 24%, respectively). Smoking was significantly less frequent among patients originating from Ethiopia (8%). Increased CVR (FRS >10%) was observed in 21% of the patients. Significantly lower rates were observed among Ethiopian patients (11%), compared with non-Ethiopians (39%). Increased CVR was correlated with increased age (p<0.05), male gender (p=0.034) and HTN (p=0.002), but not with smoking (p=0.53), change in CD4 (p=0.7) or viral suppression (p=0.64). CONCLUSION: Rates of hypertension, diabetes and smoking among patients living with HIV/AIDS were comparable to those found in the general Israeli population. Significantly lower rates of increased Framingham risk score (>or=10%) were observed among Ethiopian HIV/AIDS patients, than among non-Ethiopians. .

An outbreak of achromobacter xylosoxidans associated with ultrasound gel used during transrectal ultrasound guided prostate biopsy.

PURPOSE: We describe an outbreak of Achromobacter xylosoxidans after transrectal ultrasound guided prostate biopsy at a urology unit at a tertiary care center as well as clinical and microbiological investigation, and intervention. MATERIALS AND METHODS: In September 2008, several days after undergoing transrectal ultrasound guided prostate biopsy, 4 patients were hospitalized with fever. We reviewed the procedure and infection control practices in the urology service. Environmental cultures were obtained from equipment and materials used for the procedure. Isolates were identified by routine laboratory procedures with molecular confirmation and characterized by pulsed field gel electrophoresis. RESULTS: A. xylosoxidans was isolated from the urine of 2 patients, of whom 1 also had a positive blood culture. Review of transrectal ultrasound guided prostate biopsy revealed that the lubricant gel used in the procedure, which the biopsy needle passes through, was held in a plastic container that was repeatedly refilled from a large bag. A. xylosoxidans was isolated from this container. Pulsed field gel electrophoresis showed that the isolates obtained from patients and the gel were identical. CONCLUSIONS: Contaminated lubricant gel was the cause of this outbreak. The practice of repeatedly refilling gel containers with nonsterile gel was replaced by the use of individual sterile gel sachets in each patient. No further cases occurred. During an invasive procedure involving a sterile body site, such as transrectal ultrasound guided prostate biopsy, using sterile gel is essential. Our experience emphasizes the crucial need to review all invasive procedures from an infection control perspective.
