Do vaccines cause IMHA?
Abstract. Vaccination has been incriminated as a trigger of immune-mediated hemolytic anemia (IMHA) in dogs and in people, but evidence to support this association is lacking. In a controlled retrospective study, idiopathic IMHA was identified in 58 dogs over a 27-month period.
Can vaccines cause hemolytic anemia?
Three cases of AIHA following COVID-19 mRNA vaccination have been reported, 2 with the Moderna vaccine,5,6 and 1 with the Pfizer vaccine. All were associated with symptomatic anemia causing the patient to seek urgent medical care.
What triggers IMHA?
IMHA in dogs and cats can be triggered by different factors including infectious organisms, tumours and even drugs. It is therefore extremely important to inform your vet of any medication that your pet has recently received.
Can the vaccine cause anemia?
Aplastic anemia (AA) is an immune-mediated bone marrow failure syndrome. We report a case of severe AA that arose after the administration of a COVID-19 vaccine (the Pfizer-BioNTech mRNA vaccine), which was treated with allogeneic hematopoietic stem cell transplantation (HSCT).
Is IMHA genetic?
Idiopathic IMHA in dogs is a complex disease influenced by genetics, the immune system, the environment, and more. CHF-funded researchers are tackling this disease from all angles – developing more accurate diagnostic tests and exploring new treatment targets and medications.
Can IMHA be misdiagnosed?
In this case, the misdiagnosis of primary IMHA resulted in a catastrophe consequence, not only due to the known immune-suppressive effects of corticosteroids facilitating bacterial infection but also the high mortality rate associated with this type of infection despite proper therapy.
Does Covid cause severe anemia?
Mortality was higher in SARS-CoV-2 positive patients. In COVID-19, females had lower hemoglobin concentration than males and a higher prevalence of moderate/severe anemia (25% versus 13%, p = 0.032). In most cases, anemia was mild and due to inflammation, sometimes associated with iron and/or vitamin deficiencies.
Does hemolytic anemia go away?
Some types of acquired hemolytic anemia are short-term (temporary) and go away over several months. Other types can become lifelong (chronic). They may go away and come back again over time.
Can autoimmune hemolytic anemia be cured?
Treatment options for AIHA depend on a number of factors. If the anemia is mild, it often passes without treatment. Between 70 and 80 percent of people need no treatment or minimal intervention. However, some people will need medication, surgery, or a blood transfusion.
