Haemolacria or hemolacria is a physical condition that causes a ... Acute haemolacria can occur in fertile women and seems to be induced by hormones, [2] similarly to ...
The successful use of beta blockers supports the theory that the condition is induced by stress and anxiety. However, this etiology is not yet fully established, as the high prevalence of stress and anxiety in the modern era has not changed the incidence of this extremely rare disease, suggesting that other co-abnormalities also play a key role ...
Drug-independent autoantibodies are found in Drug-induced autoimmune hemolytic anemia because of beta-lactamase inhibitors and platinum-based chemotherapeutics. These autoantibodies can sometimes bind and react to red blood cells even in the absence of whatever drug triggered the anemia .
The damage is induced through repetitive mechanical motions such as prolonged marching (march hemoglobinuria) and marathon running. [2] [3] Mechanical damage can also be induced through the chronic condition microangiopathic hemolytic anemia or due to prosthetic heart valves. [1]
AIHA can be classified as warm autoimmune hemolytic anemia or cold autoimmune hemolytic anemia, which includes cold agglutinin disease and paroxysmal cold hemoglobinuria. These classifications are based on the characteristics of the autoantibodies involved in the pathogenesis of the disease.
A 2013 study of over 400,000 people admitted to US hospitals found that 74% developed anemia at some point during their hospital stay. [5] Iatrogenic anemia is of particular concern in intensive care medicine, [6]: 629 because people who are critically ill require frequent blood tests and have a higher risk of developing anemia due to lower hemoglobin levels and impaired production of red ...
There are also risks associated with membrane sweeping. The risks include irregular contractions, bleeding, and in 1 out of every 10 women an amniotic sac rupture, which can lead to a formal induction within 24 hours of the rupture if labor hasn't been induced. [5] The use of intrauterine catheters are also indicated.
The most common antibody isotype involved in warm antibody AIHA is IgG, though sometimes IgA is found. The IgG antibodies attach to a red blood cell, leaving their F C portion exposed with maximal reactivity at 37 °C (versus cold antibody induced hemolytic anemia whose antibodies only bind red blood cells at low body temperatures, typically 28–31 °C).
