Not the same thing, specifically:
Leukemia is a class of malignant clonal diseases of hematopoietic stem cells that are hematologic malignancies.
- The incidence of leukemia is reported to be the sixth most common overall malignancy in all regions of China.
- Clonal leukemia cells accumulate in the bone marrow and other hematopoietic tissues due to mechanisms such as uncontrolled proliferation, impaired differentiation, and blocked apoptosis, and infiltrate other non-hematopoietic tissues and organs, while inhibiting normal hematopoietic function.
- Clinical manifestations include varying degrees of anemia, bleeding, infectious fever, and enlargement of the liver, spleen, lymph nodes, and skeletal pain.
Sepsis, on the other hand, is an acute systemic infection in which pathogenic or conditionally pathogenic bacteria invade the blood circulation and grow and multiply in the blood, producing toxins.
- If the bacteria that invade the bloodstream are cleared by the body’s defenses and there are no obvious signs of toxemia, it is called bacteremia.
- Sepsis with multiple abscesses of long duration is called septicemia.
- Sepsis, if not rapidly controlled, can progress from the primary site of infection to other parts of the body, causing metastatic abscesses.
- Abscesses can occur on the surface of the brain, leading to meningitis;
- on the pericardium around the heart, causing pericarditis;
- in the lining of the heart, causing endocarditis;
- In the bone marrow, it causes osteomyelitis;
- In the large joints, causing joint pain or arthritis.
- Eventually, abscesses form anywhere in the body due to accumulation of pus, and in severe cases, infectious shock and migratory lesions occur.
As you can see, leukemia and sepsis are two different diseases and should not be confused.
