A pathological deficiency in the oxygen-carrying component of the blood, measured in unit volume concentrations of hemoglobin, red blood cell volume, or red blood cell number.

[New Latin, from Greek anaimiā : an-, without; see a-1 + haima, blood.]


(Pathology) the usual US spelling of anaemia
[C19: from New Latin, from Greek anaimia lack of blood]


(əˈni mi ə)

1. a reduction in the hemoglobin of red blood cells with consequent deficiency of oxygen in the blood, leading to weakness and pallor.
2. a lack of power, vigor, vitality, or colorfulness.
[1800–10; < New Latin < Greek anaimía want of blood. See an-1, -emia]


A condition in which the concentration of red blood cells or the amount of hemoglobin is too low to supply enough oxygen to the tissues of the body. See also sickle cell anemia.

anemic adjective

anemia, anaemia

1. a lack of blood in the body.
2. a low proportion of red cells in the blood. — anemic, anaemic, adj.

In AIHA developing secondary to infection, symptoms generally occur 2-3 weeks after the onset of infection and recover spontaneously in 2-3 weeks (2).
Warm AIHA is generally IgG dependent but can also (rarely) be immunoglobulin M (IgM) or immunoglobulin A (IgA) dependent, or there could also be more than 1 immunoglobulin class present simultaneously (eg, IgM/C3 together with IgG on the RBC membrane).

3 In suspected cases of AIHA, a positive DAT is predictive in 83% of patients, but not all cases of AIHA are DAT positive.
Psoriatic skin disorders have not been previously reported as part of multiple autoimmune syndromes along with AIHA, SLE and vitiligo.
The diagnosis of AIHA was based on the presence of an otherwise unexplained hemoglobin level < 10 g/dL or hematocrit < 30% and a positive direct anti-globulin test (DAT) for either IgG or C3 and the presence of at least one indirect marker of hemolysis: high reticulocyte count, low serum haptoglobin levels, increased serum LDH or bilirubin levels.
Additionally, her chronic AIHA came under control after 1 week of MDMP treatment, hemoglobinuria resolved and the bilirubin level decreased after 3 d of MDMP; the only side effect was a mild cushingoid appearance that regressed after 2 months of the treatment, despite continuation of a relatively low dose of MP (48 mg/d).
Chris Kirk, SGSa[euro](tm)s chief executive, said that the Brazilian company, with all needed accreditations and qualifications including AIHA and Inmetro 17.
5) There have been a few case reports of pSS associated with AIHA and immune mediated thrombocytopenia.
1 had also never heard of AIHA, which might be a worthy article in the future; my best friend lost her cat to this disease who had the same symptom - "just off.
The initial symptoms and laboratory findings of hemolytic anemia, depressed hemoglobin and haptoglobin concentrations, increased lactate dehydrogenase, increased indirect bilirubin, and an IgG-positive result in a direct antiglobulin test were all consistent with those typically indicative of warm antibody AIHA, although the reticulocytosis often also associated with AIHA was not noted (1).
