![]() In addition, the balance between neutrophils and lymphocytes, indicated by neutrophil to lymphocyte ratio (NLR), is being studied extensively. ![]() The quality and quantity of neutrophils and lymphocytes is crucial for the efficient functioning of the immune system. Immunosuppressive drugs are also used to reduce the activity of immune system. The treatments are often symptomatic, and include the use of analgesics, and anti-inflammatory drugs. SLE is characterized by the development of a butterfly rash on the face along with hair loss, mouth sores, fever and increased sensitivity to sunlight. Hence, a combined state of neutropenia and lymphocytosis may be observed.įelty syndrome involves joint pain and swelling, recurrent infections, fatigue, bone and joint deformities, etc. These cells infiltrate the bone marrow and hamper neutrophil production. Radiation therapy and bone marrow transplant may be advised for certain cases involving the development of secondary cancers.Īutoimmune diseases Certain autoimmune diseases including Felty syndrome (occurs in association with rheumatoid arthritis) and systemic lupus erythematosus (SLE) are characterized by an inflammatory response, and involve an increase in the number of LGLs. Choice of the drug varies with each individual patient. is the general option for reducing the lymphocyte count. Symptomatic treatments along with chemotherapy involving drugs like daunorubicin, fludarabine, rituximab, alemtuzumab, etc. ![]() Night sweats, frequent colds, fatigue, recurring infections, loss of appetite and weight loss are the associated symptoms. For some patients, the lab test may indicate a normal WBC count, and hence a differential count and bone marrow test is essential for the right diagnosis. Such uncontrolled clonal expansion interferes with the normal production and differentiation of neutrophils as well. As a result, the lymphocyte counts in such patients are high. AML, ALL and CLL involve the clonal expansion of progenitor lymphocytes. LGL and T-LGL leukemias arise due to an uncontrolled proliferation of NK cells and cytotoxic T-cells respectively, and are the most common leukemias that cause neutropenia. T-cell large granular lymphocyte (T-LGL) leukemia.Large granular lymphocyte (LGL) leukemia. ![]() Increase in lymphocytes is generally the result of acute bacterial and viral infections, leukemias, lymphomas, ulcerative colitis, and acute-phase reactions (observed as a response to acute stress). NK cells are cytotoxic lymphocytes that bring about the destruction of infected cells in an antibody-dependent as well as antibody-independent processes. The B lymphocytes participate in immune response by antibody production, whereas the T lymphocytes bring about the destruction of pathogens or infected cells with the help of such antibodies. These are categorized as B lymphocytes, T lymphocytes and natural killer (NK) cells or large granular lymphocytes (LGL). Lymphocytes form the primary component of the processes that confer adaptive immunity. Neutropenia results in compromised immunity, and increases the susceptibility to infections. Decreased neutrophils, can be the result of immunosuppressive drugs, antipsychotics, chemotherapy, as also certain viral diseases. Segmented neutrophils circulate in a mature form, and possess a divided or segmented nucleus while banded neutrophils are immature, and have a band-shaped nucleus. They occupy the highest count amongst white blood cells, and are divided into two types, segmented neutrophils (segs or polys) and banded neutrophils (bands). These phagocytic cells provide the first line of defense against foreign bodies and pathogens, and play a major role in activating an immune response against a pathogenic agent. Neutrophils belong to the class polymorphonuclear granulocytes, and have a multilobed nucleus. Abnormally low neutrophil count (neutropenia) as well as a high lymphocyte count (lymphocytosis) can be the result of viral infection or an indication of the adult-onset form of cyclic neutropenia, certain lymphoproliferative disorders like lymphomas and leukemias or certain autoimmune diseases. Abnormal numbers of these cells influence the body’s ability to fight infections. Neutrophils and lymphocytes are types of white blood cells that play an important and unique role in providing immunity against infections.
