Lymphocytosis: mainly seen in the treatment of adrenal cortical hormone, alkylating agent, anti-lymphocyte globulin, as well as radiation injury, immune deficiency, gamma globulin deficiency and so on.
abstract
Total number of adult lymphocytes
The lymphocyte count of normal adults is 1000 ~ 4800/L, and that of children (under 2 years old) is 9500/3000. 1500g/L reached the normal low value at the age of 0/6, and the peripheral blood T cells (helper T CD4 cells) were 65%. The absolute number of T cells decreased, and lymphocytes in most patients decreased, especially CD4 cells.
The average value of CD4 T cells in adult peripheral blood is 1 100/? l(300~ 1300/？ L), the absolute number of CD8 (suppressor) T cells in other major T cell subsets is 600/? l( 100~900/？ l).
etiology
Iatrogenic lymphopenia can be caused by cytotoxic chemotherapy, radiotherapy and injection of lymphocyte globulin. Long-term use of psoralen and ultrasonic radiation can damage T cells in patients with psoriasis. Glucocorticoid can lead to lymphocyte reduction by inducing cell damage.
Systemic diseases related to autoimmunity (such as SLE, rheumatoid arthritis and myasthenia gravis) can cause lymphopenia. Protein's deficiency bowel disease may be accompanied by lymphopenia.
Symptoms, signs and diagnosis
Lymphocytosis generally does not cause symptoms. It is usually the recurrence of other diseases, especially virus, fungus or protozoan infection. The lymphocyte count can be determined. Lymphocyte subsets were detected by multi-parameter flow cytometry, and cells were classified and identified according to their expressed antigen types.
What if the percentage of lymphocytes is low?
1. Check the blood routine again to understand the changes of blood picture; .
2. Do you have any other symptoms besides fever? Check the chest X-ray if necessary.
3. Try traditional Chinese medicine decoction treatment, which may be effective.
This hemogram is suspected to be a virus infection, so the doctor repeatedly treated it with antiviral drugs. One possibility is that the antiviral time is short and there is no complete recurrence; One possibility is that it is complicated with bacterial infection. So check the blood routine.
