Thrombocytopenia is a condition in which there is a lower-than-normal number of platelets in the blood. It may result in easy bruising and excessive bleeding from wounds or bleeding in mucous membranes and other tissues.
Of the 203 million people who have received at least one dose of a covid-19 vaccine, more than 9 million have enrolled in a program to share information about their health since getting the shot.
The current study found that people were at a slightly higher than normal risk of blood clots after receiving Oxford-AstraZeneca and Pfizer vaccines.
A deep look into a nationwide mass vaccination setting in Israel revealed that the BNT162b2 (Pfizer–BioNTech) vaccine is not linked with an elevated risk of a majority of the adverse events under study, with the exception of myocarditis. However, even that potentially severe adverse event is much more pervasive following the infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), found a new study published in the New England Journal of Medicine (NEJM).
Researchers aim to better understand the population-level thrombotic risks post COVID-19 vaccination with both the ChAdOx1-S and BNT162b2 vaccines.
A study published on medRxiv* preprint server reported the over-time changes in the ability of the serum to activate platelets in vitro.
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infected individuals often suffer from thrombocytopenia, a condition associated with low platelet counts. The cytokine thrombopoietin regulates platelet count. Previous studies have reported that thrombocytopenia can increase the coronavirus disease 2019 (COVID-19) mortality rate by about five times.
Oncotarget published "Eltrombopag and its iron chelating properties in pediatric acute myeloid leukemia" which reported that the standard treatment for pediatric AML currently consists in a combination of cytarabine and antracycline.
A study has revealed that adenovirus vector and mRNA-COVID-19 vaccines are associated with an increased risk of thromboembolism and thrombocytopenia.
A new study published on the preprint server medRxiv* presents an analysis of the differences between recorded vaccination side effects vs. early COVID-19 symptoms. The researchers focused on four vaccines, namely, Pfizer-BioNTech (PB) mRNA (BNT162b2) vaccine, based on messenger ribonucleic acid encoding the viral spike protein; the Moderna mRNA (mRNA-1273) vaccine; the Oxford-AstraZeneca (O-AZ) adenovirus-vectored vaccine; and the Janssen adenovirus-vectored Ad26.COV2.S).
Now, a new systematic review has been published in the journal Animals that focuses on the clinical symptoms in felines diagnosed with SARS-CoV-2 worldwide.
Researchers in Germany have provided evidence that a booster shot of a messenger RNA (mRNA)-based coronavirus disease 2019 (COVID-19) vaccine following prime immunization with AstraZeneca’s adenoviral vector-based vaccine is sufficient to achieve high levels of neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
A McMaster University team of researchers recently discovered how, exactly, the COVID-19 vaccines that use adenovirus vectors trigger a rare but sometimes fatal blood clotting reaction called vaccine-induced immune thrombotic thrombocytopenia or VITT.
New research has shown that early testing for blood clots in patients who had received the AstraZeneca/Oxford vaccine led to them being treated successfully, highlighting the need for heightened awareness of the risk among doctors.
A new study, released as a preprint on the medRxiv* server, indicates that pregnant women are more likely to develop severe disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
Vivid photos of the red "COVID arm" rash and reports of facial swelling in patients who have received dermatological fillers after Pfizer-BioNTech or Moderna vaccination for COVID-19 may increase patients' concerns about mRNA vaccine side effects and contribute to vaccine hesitancy.
Healthcare professionals and public health authorities have a central role in discussing vaccination against COVID-19 with their patients.
A new study, which was conducted by Vishala Mishra and Joseph P. Dexter at Madras Medical College, Chennai, India, suggests that the infamous pause in the administration of the Johnson & Johnson (J&J)/Janssen COVID-19 vaccine, advised by the FDA, has left doubt about the veracity of vaccine safety claims. This is a development that may have engendered vaccine hesitancy in a segment of the population.
A recent article published in the journal Frontiers in Tropical Diseases assessed the threat of emerging zoonotic and vector-borne tropical diseases.
Even as a host of vaccines have been rolled out to counter the coronavirus disease 2019 (COVID-19) pandemic, some serious adverse effects have been reported, in the form of thrombocytopenia. A new study in the journal Vaccine reports the results of an evaluation of reported cases of this condition, using data from the Vaccine Adverse Event Reporting System (VAERS).
A team of researchers has conducted a systematic review to identify laboratory factors that can predict the risk of severe and critical COVID-19 as well as associated mortality rates. The team – from institutions in India and the USA – recently published their findings in the Journal of Clinical Medicine Research.
