ABSTRACT
BACKGROUND: Heart failure is a major cause of morbidity and mortality among older adults. Sacubitril-Valsartan (Sac/Val) has been shown to improve patients' outcomes; however, its safety profile among older adults has not been adequately examined. We therefore aimed to examine its safety profile among this population. METHODS: We conducted a retrospective pharmacovigilance study utilizing the FDA's database of safety reports (FAERS). We employed disproportionality analysis comparing Sac/Val to angiotensin receptor blockers (ARBs). We aim to evaluate the reporting of pre-defined adverse events associated with Sac/Val (hypotension, acute kidney injury (AKI), hyperkalemia and angioedema) in two age groups: adults (< 75 years) and older adults (≥ 75). For each subgroup, we calculated reporting odds ratio (ROR) and compared them by calculating P for interaction. RESULTS: The FAERS database encompassed 18,432 unique reports of Sac/Val. Of them, 12,630 (68.5%) subjects were adults (< 75 years), and 5802 (31.5%) were older adults (≥ 75 years), with a median age (IQR) of 68 (59-77). When compared to ARBs, Sac/Val was associated with higher reporting of hypotension, lower reporting of acute kidney injury (AKI) and hyperkalemia, and similar reporting of angioedema. Notably, we did not observe a significant interaction between the age subgroups and the risk estimates (AKI: Pinteraction = 0.72, hyperkalemia: Pinteraction = 0.94, hypotension: Pinteraction = 0.31, and angioedema: Pinteraction = 0.61). CONCLUSIONS: In this postmarking study, none of the prespecified adverse events was reported more frequently in older adults. These findings provide reassurance for safety use of Sac/Val in older adults.

INTRODUCTION: Extracorporeal photopheresis (ECP) is considered an effective treatment for patients with chronic graft vs host disease (cGVHD) and demonstrates efficacy in ameliorating GVHD. The mechanism by which ECP acts against cGVHD is not fully understood. Preliminary observations have hinted at the potential involvement of neutrophil extracellular traps (NETs) formation in the pathogenesis of cGVHD. We aimed to assess the influence of ECP on the formation of NETs in patients with cGVHD as a potential mechanism in this setting. METHODS: Patients treated with ECP for cGVHD at the Rabin Medical Center were included in this study. Blood samples were obtained at three different time points: before starting an ECP cycle, at the end of the first day of treatment, and 24 h following the initiation of the ECP treatment cycle. Neutrophils were harvested from all blood samples. NET formation was assessed by measurement of NET-bound specific neutrophil elastase activity and by immunofluorescence staining. RESULTS: Six patients (two females and four males) with cGVHD were included in the study. We observed a significant increase in NET formation among all six patients following ECP. Net-bound specific neutrophil elastase activity was elevated from a median value of 2.23 mU/mL (interquartile range [IQR] 2.06-2.47 mU/mL) at baseline to a median value of 13.06 mU/mL (IQR 10.27-15.97 mU/mL) immediately after the treatment and to a peak median value of 14.73 mU/mL (IQR 9.6-22.38 mU/mL) 24 h following the initiation of the ECP cycle. A qualitative assessment of NET formation using immunofluorescence staining has demonstrated markedly increased expression of citrullinated histone H3, a marker of NET formation, following ECP treatment. CONCLUSIONS: Our preliminary data indicate that ECP induces NET formation among patients with cGVHD. The contribution of increased NET formation to the therapeutic effect of cGVHD should be further investigated.
ABSTRACT
INTRODUCTION: We aimed to assess the natural annual trends in the levels of haemoglobin, haematocrit, and mean corpuscular volume (MCV) in a population of adults, together with the influence of different clinical parameters on these trends. METHODS: A retrospective analysis was carried out on data from a large cohort of subjects attending a screening centre in Israel. For each subject, the yearly average change of haemoglobin, haematocrit, and MCV was calculated. Statistical analysis was performed for the whole cohort and for different subgroups. RESULTS: The study included 3,551 subjects. The average annual rates of decline were found to be -0.0550 g/dL (95% confidence interval [CI] -0.0590 g/dL to -0.0503 g/dL) and -0.097% (95% CI -0.112% to -0.083%) for haemoglobin and haematocrit, respectively. An average annual increase in the MCV level by 0.184 fL (95% CI 0.168 fL-0.200 fL) was found. Among men, the rate of decline in haemoglobin was found to be twice as high compared with women -0.06 g/dL versus -0.03 g/dL, respectively (p = 0.0063). In a multivariate analysis, gender remained the only parameter significantly associated with the annual decline of haemoglobin (p = 0.0001). CONCLUSION: An annual average decrease in the levels of haemoglobin and haematocrit together with an annual increase in MCV was found. These changes were more prominent in men.

BACKGROUND: Previous studies have demonstrated an association between proton pump inhibitors (PPI) use and vitamin B12 deficiency. However, data regarding PPI use and elevated serum homocysteine level, an important marker of vitamin B12 deficiency, are scant. METHODS: Data were collected from medical records of subjects examined at a screening center in Israel. Cross sectional analysis was conducted on 25,953 subjects. Levels of vitamin B12 and homocysteine were compared between subjects who consumed PPI medications and those who did not. RESULTS: The mean age of the study population was 45 years and 33% were females. Subjects who received PPI medications had a minor higher vitamin B12 levels (320 pmol/L vs 300 pmol/L, p=0.024). Levels of vitamin B12 remained higher in females receiving PPI medications after performing a stratified analysis according to subjects' gender. Homocysteine levels were higher in subjects receiving PPI medications as compared to those who did not (12.0 µmol/L vs 11.6 0 µmol/L, p<0.001). Levels remained higher in female subjects after performing a stratified analysis according to subjects' sex. There was no statistically significant difference in the prevalence of vitamin B12 deficiency (according to two cutoffs: vitamin B12≤200 or ≤140 pmol/L) as well as the prevalence of hyperhomocysteinemia (defined as homocysteine >15.0 µmol/L) between the two groups. CONCLUSIONS: According to our study, no association was found between PPI medication use and vitamin B12 deficiency or hyperhomocysteinemia. Patients receiving PPI medications had slightly higher levels of vitamin B12 and homocysteine, however these differences were too small to have any clinical relevance.

Chemotherapy-based approaches still constitute an essential feature in the treatment paradigm of adult acute lymphoblastic leukemia (ALL). The German Multicenter Study Group (GMALL) is a well-established protocol for ALL. In this study, we assessed our recent experience with the GMALL 07/2003 protocol reviewing all adult ALL patients who were treated with GMALL in three major centers in Israel during 2007-2020. The analysis comprised 127 patients with a median age of 41 years (range 17-83). Sixty-two were B-ALL (49%), 20 (16%) patients were Philadelphia chromosome positive ALL, and 45 (35%) were T-ALL. The 2-year and 5-year overall survival rates were 71% and 57%, respectively. The 2-year relapse rate was 30% with 2-year and 5-year leukemia-free survival rates of 59% and 50%, respectively. Adolescents and young adults experienced significantly longer overall survival (84 months versus 51 months; p=0.047) as well as leukemia-free survival compared with older patients (66 months versus 54 months, p=0.003; hazard ratio=0.39, 95% confidence interval, 0.19-0.79; p=0.009). T-ALL patients had longer survival compared to B-ALL patients while survival was comparable among Philadelphia chromosome positive patients and Philadelphia chromosome negative patients. An increased number of cytogenetic clones at diagnosis were tightly associated with adverse prognosis (15-month survival for ≥2 clones versus 81 months for normal karyotype; p=0.003). Positive measurable residual disease studies following consolidation were predictive for increased risk of relapse (64% versus 22%; p=0.003) and shorter leukemia-free survival (11 months versus 42 months; p=0.0003). While GMALL is an effective adult regimen, a substantial patient segment still experiences relapse.

BACKGROUND: Emerging data suggest increased arterial thrombosis risk in the months preceding a cancer diagnosis. OBJECTIVES: To assess whether patients without documented vascular risk factors or pre-existing cardiovascular disease have a higher relative risk of cancer 12 months after arterial thrombotic events (ATE), compared to unselected patients. PATIENTS/METHODS: A population-based cohort study of Clalit Health Services (CHS) database included CHS members ≥25 years without prior cancer or ATE (n = 2 804 584). An iterative matching process selected 10 potential controls chronologically for each consecutive exposed, age- and sex-matched (actual controls drawn 1:1 from a lot). Study exposure, ATE, was defined as ischemic stroke, transient ischemic attack, myocardial infarction or systemic arterial thromboembolism during hospitalization. The outcome was newly-diagnosed cancer within 12 months, based on Israeli national cancer registry. Cox proportional hazards multivariate regression calculated hazard ratio (HR) for outcomes, adjusted for cancer risk factors. Analysis also performed for three subgroups: age ≤50 years; no cardiovascular risk factors; no prior cardiovascular disease. RESULTS: The full ATE and matched control cohorts included 43 108 patients. The 12-month cumulative incidence of cancer (95% confidence interval) was 0.020 (0.019-0.022) in the ATE cohort and 0.012 (0.011-0.013) in controls, corresponding to an adjusted HR of 1.665 (1.489-1.862). The relative risk of cancer was high in all subgroups up to a HR of 3.754 (1.912-7.372) in patients without cardiovascular risk factors. CONCLUSION: There is an increased risk of previously undiagnosed cancer at 12 months after ATE, especially in patients without documented vascular risk factors or pre-existent cardiovascular disease.

BACKGROUND: Streptococcus gallolyticus subspecies gallolyticus is a known pathogen that causes infective endocarditis, and most cases involve the left heart valves. We present the first reported case of prosthetic tricuspid valve endocarditis caused by this microorganism. Relevant literature is reviewed. CASE PRESENTATION: A 67-year-old Jewish female with a history of a prosthetic tricuspid valve replacement was admitted to the emergency department because of nonspecific complaints including effort dyspnea, fatigue, and a single episode of transient visual loss and fever. No significant physical findings were observed. Laboratory examinations revealed microangiopathic hemolytic anemia and a few nonspecific abnormalities. Transesophageal echocardiogram demonstrated a vegetation attached to the prosthetic tricuspid valve. The involved tricuspid valve was replaced by a new tissue valve, and Streptococcus gallolyticus subspecies gallolyticus was grown from its culture. Prolonged antibiotic treatment was initiated. CONCLUSIONS: Based on this report and the reviewed literature, Streptococcus gallolyticus should be considered as a rare but potential causative microorganism in prosthetic right-sided valves endocarditis. The patient's atypical presentation emphasizes the need for a high index of suspicion for the diagnosis of infective endocarditis.

OBJECTIVES: Early stages of diabetes are associated with an increased glomerular filtration rate (GFR). Little is known, however, about the change in GFR among patients with impaired fasting glucose (IFG). We aimed to evaluate the yearly decline rate of GFR among IFG patients. METHODS: A retrospective analysis of a large cohort of subjects attending a medical screening center in Israel. Patients with diabetes mellitus and patients with decreased estimated GFR (eGFR) were excluded. We divided the cohort into 2 subgroups; Healthy controls and impaired fasting control subjects. For each group, we calculated the average yearly estimated GFR decline (ΔeGFR). The results were adjusted for age, BMI, hypertension and smoking status. RESULTS: 8176 subjects met the inclusion criteria. The median follow up time was 4.8â¯years (range 2.0 to 13.4). For the whole cohort (men and women), yearly ΔeGFR was -0.68 among healthy controls, andâ¯-â¯0.47 among IFG patients (pâ¯=â¯.003). Among men, average yearly ΔeGFR in healthy controls and IFG patients was -0.7 andâ¯-â¯0.4, respectively (pâ¯=â¯.0002). All results remained significant after adjusting for age, BMI, hypertension, smoking status and level of HDL and triglycerides. In contrast, among IFG women there was no significant difference in ΔeGFR in comparison with healthy women. CONCLUSIONS: Impaired fasting glucose is associated with a decreased rate of GFR reduction compared with healthy subjects. This effect is gender dependent - observed in men but not in women. A mechanism of glomerular hyperfiltration might be involved.
