Leukopenia (from Greek λευκός (leukos) 'white' and πενία (penia) 'deficiency') is a decrease in the number of leukocytes (WBC).Found in the blood, they are the white blood cells, and are the body's primary defense against an infection.
There are also two general causes of cytopenia: autoimmune and refractory. Autoimmune cytopenia is caused by an autoimmune disease when your body produces antibodies to destroy the healthy blood cells. Refractory cytopenia is caused by bone marrow not producing healthy blood cells, and can be a result of cancer.
Reduced red blood cell count (anemia) Less body hair. Gynecomastia (male breast development) Reduced Drive (Low Libido) One of the most common signs of low testosterone is a low drive (aka low ...
Aplastic anemia [2] (AA) [3] is a severe hematologic condition in which the body fails to make blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. [4] Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6]
Lymphocytopenia is commonly caused by a recent infection, such as the common cold or COVID-19. [3]Lymphocytopenia, but not idiopathic CD4+ lymphocytopenia, is associated with corticosteroid use, infections with HIV and other viral, bacterial, and fungal agents, malnutrition, systemic lupus erythematosus, [4] severe stress, [5] intense or prolonged physical exercise (due to cortisol release ...
Megaloblastic anemia caused by vitamin B 12 deficiency is characterized by red blood cells that are larger than normal and are unable to deliver oxygen to the body's organs. [7] [8] The clinical case indicates an altered synthesis of DNA, in which vitamin B 12 is essential for the production and maturation of red blood cells in the bone marrow. [8]
Figure shows normal red blood cells flowing freely in a blood vessel. The inset image shows a cross-section of a normal red blood cell with normal hemoglobin. [34] The causes of anemia may be classified as impaired red blood cell (RBC) production, increased RBC destruction (hemolytic anemia), blood loss and fluid overload (hypervolemia ...
The normal range for hemoglobin is 13.8 to 17.2 grams per deciliter (g/dL) for men and 12.1 to 15.1 g/dL for women. [6] Low hemoglobin indicates anemia but will be normal for LID. [5] Normal serum iron is between 60 and 170 micrograms per deciliter (μg/dL). [7] Normal total iron-binding capacity for both sexes is 240 to 450 μg/dL. [6]
