What is the reason for the re-emergence of obstructive anaemia?

Restorative obstructive anaemia (Aplastic Anemia, known as AA) is a rare blood disease characterized by the inability of the bone marrow to produce enough new blood cells to reduce the number of red cells, white cells and slabs. The disease can occur at any age, but is most common among young people and middle-aged people. The following are the possible causes of regenerative obstructive anaemia, divided into two categories: congenital and acquired:Pregenital causesCongenital regenerative obstructive anaemia is usually associated with genetic factors that can lead to abnormal functioning of bone marrow stem cells.Genetic diseases:Fanconi Anemia: This is a genetic bone marrow failure syndrome, and patients may carry mutations of genes that cause membrane cell dysfunction.Dyskeratosis Congenita: This is a rare genetic disease that affects bone marrow and the cells of other organizations.Shwachman-Diamund syndrome: This is a genetic disease affecting multiple organs, including bone marrow.Genetic mutation:The mutations of certain genes, such as RUX1, DKC1, ERC1, etc., may result in the non-normal division and maturity of bone marrow stem cells.Reasons for acquiring sexAccess to sexually regenerative obstructive anaemia is usually caused by external factors that can directly damage bone stem cells or the micro-environment of bone marrow.Drugs and chemicals:Drugs: Certain drugs, such as anti-cancer, epilepsy, antibiotics (e.g., Clocin) and non-methrinics (NSAIDs), may lead to bone marrow inhibition.Chemical substances: Long-term exposure to benzene, pesticides, solvents and other harmful chemical substances may damage bone marrow.Radioactivity:Long-term or large doses of exposure to radiation, such as nuclear radiation or medical treatment, may damage bone marrow stem cells.Virus infection:Certain viruses, such as hepatitis B virus, hepatitis C virus, human microvirus B19 and atypical pneumonia virus, may be associated with the occurrence of regenerative obstructive anaemia.Self-immunological diseases:Self-immuno-immuno-diseases can lead to an erroneous attack by the immune system on its own bone marrow stem cells, a situation called regenerative obstructive anaemia induced by immunization.Pregnancy:Although rare, regenerative obstructive anaemia may occur during pregnancy, which may be related to changes in the immune system during pregnancy.Other blood diseases:This is a rare blood disease that can lead to bone marrow failure, for example, in systolic haemoglobin urine (PNH).Incidence mechanismThe mechanism for re-emergence of obstructive anaemia is complex and may involve the following:stem cell damage:The regenerative capacity of bone marrow stem cells may be impaired by genetic factors, drugs, chemicals or radiation.Immunomediate injuries:The immune system may produce its own antibodies for bone marrow stem cells or damage stem cells by means of an immunometric response by cell.Micro-environmental changes in bone marrow:Micro-environments in the bone marrow are essential for stem cell survival and dichotomy, and any factors affecting micro-environments can cause regenerative obstructive anaemia.Cell failure:Marrow stem cells may cause procedural cell deaths (crazy) for various reasons, leading to reduced blood cell formation.Diagnosis and treatmentDiagnosis of regenerative obstructive anaemia usually needs to be determined through blood tests, bone marrow work tests and possible genetic tests. Treatment includes:Supportive treatment: such as blood transfusion, antibiotics and prevention of infection.Immunosuppression treatment: The use of drugs to suppress the immune system to prevent attacks on bone marrow stem cells.Hemogenic growth factors: e.g. erythrocyte-promotive (EPO) and particle-cell concentration irritation factors (G-CSF).Bone marrow transplants: For some patients, bone marrow transplants may be the only cure for regenerative obstructive anaemia.Overall, the causes of regenerative obstructive anaemia are multiple, including genetic and environmental factors. Understanding these reasons helps doctors to develop more effective diagnostic and therapeutic programmes. For patients, timely diagnosis and treatment are essential to improve the prognosis.
