Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rapidly spread across the world, killing more than 4 million individuals globally, with 240 million individuals being confirmed by laboratory tests. Among different therapeutic strategies to prevent SARS-CoV-2 infection, vaccines are the most promising approach for curbing the pandemic. They elicit an immune neutralizing response and thus offer… Continue reading Hypertension after anti-COVID-19 vaccination

A Three-Case Series of Thrombotic Deaths in Patients over 50 with Comorbidities Temporally after modRNA COVID-19 Vaccination
Coronavirus disease 2019 (COVID-19) is the most dramatic pandemic of the new millennium; to counteract it, specific vaccines have been launched in record time under emergency use authorization or conditional marketing authorization by virtue of a favorable risk/benefit balance. Among the various technological platforms, there is that exploiting a nucleoside-modified messenger RNA (modRNA), such as… Continue reading A Three-Case Series of Thrombotic Deaths in Patients over 50 with Comorbidities Temporally after modRNA COVID-19 Vaccination
Longitudinal multi-omics analyses link gut microbiome dysbiosis with recurrent urinary tract infections in women
Recurrent urinary tract infections (rUTIs) are a major health burden worldwide, with history of infection being a significant risk factor. While the gut is a known reservoir for uropathogenic bacteria, the role of the microbiota in rUTI remains unclear. We conducted a year-long study of women with (n = 15) and without (n = 16) history of rUTI, from… Continue reading Longitudinal multi-omics analyses link gut microbiome dysbiosis with recurrent urinary tract infections in women
Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave
Cardiovascular adverse conditions are caused by coronavirus disease 2019 (COVID-19) infections and reported as side-effects of the COVID-19 vaccines. Enriching current vaccine safety surveillance systems with additional data sources may improve the understanding of COVID-19 vaccine safety. Using a unique dataset from Israel National Emergency Medical Services (EMS) from 2019 to 2021, the study aims… Continue reading Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave
Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19
Risk of SARS-CoV-2 reinfection among unvaccinated people with prior COVID-19 is a subject of debate.1,2 We performed a survival analysis in a large US population to assess the degree and duration of protection associated with natural immunity in unvaccinated individuals MethodsThis cohort study used data from patients tested for SARS-CoV-2 at 1300 sites of care… Continue reading Rates of COVID-19 Among Unvaccinated Adults With Prior COVID-19
SARS-CoV-2 vaccination can elicit a CD8 T-cell dominant hepatitis
Background & AimsAutoimmune hepatitis episodes have been described following SARS-CoV-2 infection and vaccination but their pathophysiology remains unclear. Here, we report the case of a 52-year-old male, presenting with bimodal episodes of acute hepatitis, each occurring 2-3 weeks after BNT162b2 mRNA vaccination and sought to identify the underlying immune correlates. The patient received first oral… Continue reading SARS-CoV-2 vaccination can elicit a CD8 T-cell dominant hepatitis
SARS-CoV-2 Naturally Acquired Immunity vs. Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: a Retrospective Cohort Study
Background: Waning of protection against infection with SARS-CoV-2 conferred by 2 doses of the BNT162b2 vaccine begins shortly after inoculation and becomes substantial within four months. With that, the impact of prior infection on incident SARS-CoV-2 reinfection is unclear. Therefore, we examined the long-term protection of naturally acquired immunity (protection conferred by previous infection) compared… Continue reading SARS-CoV-2 Naturally Acquired Immunity vs. Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: a Retrospective Cohort Study
Immune-mediated hepatitis with the Moderna vaccine, no longer a coincidence but confirmed
... DiscussionThis case illustrates immune-mediated hepatitis secondary to the Moderna vaccine, which on inadvertent re-exposure led to worsening liver injury with deranged synthetic function. This occurred in a well man with no other medical problems. The onset of jaundice associated with the mRNA vaccine was unusually rapid. This was also illustrated in the other cases… Continue reading Immune-mediated hepatitis with the Moderna vaccine, no longer a coincidence but confirmed
COVID-19 Early Treatment with Non-Steroidal AntiInflammatory Drugs Reduces Hospitalizations andSymptom Duration
BackgroundAt the beginning of the SARS-CoV-2 pandemic we stated that,given the new virus and the little-known disease it caused, in theabsence of Evidence-Based Medicine indications, patients shouldhave been treated with drugs already available, useful to counteractthe pathophysiology of the COVID-19 [1]. Recent literature hasconfirmed that this could be a successful approach, demonstratingthat an early treatment… Continue reading COVID-19 Early Treatment with Non-Steroidal AntiInflammatory Drugs Reduces Hospitalizations andSymptom Duration
