Aplastic anemia is not contagious and has a minor hereditary factor, meaning that if a family member has aplastic anemia, it is generally not inherited by the next generation. The cause of aplastic anemia is still unclear, but possible reasons include: 1. Damage to hematopoietic stem cells. After the hematopoietic stem cells are damaged, it leads to limited stem cell proliferation and reduced hematopoiesis. 2. Damage to the hematopoietic microenvironment. Damage to the hematopoietic microenvironment can lead to changes that disrupt the regeneration of hematopoietic stem cells. 3. Immune factors. Immune factors can cause immune damage, directly damaging hematopoietic stem cells, thereby causing bone marrow regeneration disorders.

Are the liver and kidney functions normal in patients with aplastic anemia?

Patients with aplastic anemia generally have normal liver and kidney functions. However, in certain special circumstances, abnormalities in liver and kidney functions may occur, including: Firstly, the routine treatment for aplastic anemia mainly includes the immunosuppressant cyclosporine and the hematopoietic stimulant androgens. The primary side effect of cyclosporine is renal toxicity. Therefore, during the use of cyclosporine, it is necessary to monitor the concentration of cyclosporine; excessive levels can lead to renal dysfunction. Androgens, including stanozolol and danazol, primarily cause hepatic toxicity; hence, it is necessary to monitor liver and kidney functions during treatment of aplastic anemia. The second factor that may cause liver and kidney function abnormalities is severe anemia. Long-term severe anemia can lead to tissue ischemia and hypoxia in the liver or kidneys, and if prolonged, it can cause abnormalities in liver and kidney functions. (Medication use should be carried out under the guidance of a physician.)

The differences between aplastic anemia and megaloblastic anemia.

Aplastic anemia is a type of bone marrow failure syndrome where patients can present with reduced total blood cells in the peripheral blood, without enlargement of the liver, spleen, or lymph nodes, and an increased ratio of peripheral blood lymphocytes. Bone marrow indicates low regeneration, reduced hematopoietic tissue, and increased non-hematopoietic tissue, with the condition arising from changes in the bone marrow microenvironment leading to a reduction in blood cells. Megaloblastic anemia, also known as nutritional anemia, is primarily caused by a lack of folate and vitamin B12, leading to a red blood cell synthesis disorder and resulting in anemia. Severe megaloblastic anemia can also present with reduced total blood cells. However, the red blood cells typically exhibit macrocytic anemia. In contrast, aplastic anemia generally presents with normocytic anemia.

Can patients with aplastic anemia drink corn silk water?

Patients with aplastic anemia can drink corn silk tea, but corn silk tea has no therapeutic effect on aplastic anemia. Aplastic anemia is caused by various causes and mechanisms leading to bone marrow failure, mainly characterized by decreased bone marrow hematopoietic function, decreased total blood cells, and the resulting anemia, bleeding, and infection syndrome. The pathogenesis of aplastic anemia is not clear, mainly due to immune abnormalities. The treatment is mainly the use of immunosuppressants such as cyclosporine and hematopoietic agents, primarily androgens. Corn silk tea does not have a therapeutic effect on the mechanisms of this disease.

Does aplastic anemia easily cause oral ulcers?

Patients with aplastic anemia are more prone to oral ulcers. Aplastic anemia is a type of bone marrow failure syndrome, where there is a decrease in white blood cells, red blood cells, and platelets in the peripheral blood to various extents. Long-term anemia can lead to mucosal ischemia and hypoxia. The reduction in white blood cells weakens the mucosal barrier's protective function, making it susceptible to bacterial invasion and thus prone to oral ulcers. Additionally, patients with anemia often have poor diets over long periods, leading to a deficiency in various vitamins, which is another reason why they are prone to oral ulcers. If symptoms like joint pain are present along with oral ulcers, further rheumatological and immunological tests should be conducted to rule out rheumatic and immune system diseases.

What medicine is used for aplastic anemia?

Aplastic anemia, whether acute or chronic, primarily uses immunosuppressive agents and hematopoietic stimulants for treatment. Cyclosporine is commonly used clinically among immunosuppressants, while the medicines stimulating bone marrow hematopoiesis mainly include androgens such as danazol and stanozolol. These medications all have associated adverse reactions: immunosuppressants can lead to hypertension, hyperglycemia, impaired liver and kidney function, and gum hypertrophy, while the main adverse reactions of hematopoietic androgens are liver damage. (Please use medications under the guidance of a doctor.)
