Linear regression analysis showed that, the absolute counts of total lymphocytes, CD3+, CD4+, CD4+CD38+, CD4+CD28+, were positively associated with formula-fed infants and infant's infections in the first 4 months of age. (cambridge.org)
Total leukocyte and lymphocyte counts diminished after 6 months of DMF therapy. (neurology.org)
Hemoglobin (Hb) = 9 g/dl, - Total leukocyte count = 3 x 109/L, - Platelet count (PC) = 100 x 109/L , - Total bilirubin and/or Alkaline Phosphatase = 2.5 times the institutional upper normal limit. (who.int)

Patients with IgAD are at some increased risk of developing severe reactions after receiving blood products. (medscape.com)
IgA-deficient patients with immunoglobulin E (IgE)-class anti-IgA antibodies are at risk for anaphylaxis if they receive blood or intravenous immunoglobulin, but this situation is extremely rare. (medscape.com)
Peripheral blood samples and radiographic data were collected longitudinally for up to 8 weeks from 158 laboratory-confirmed COVID-19 patients. (medsci.org)
Sequential monitoring showed a sustained increase in lymphocytes counts and significantly decreased levels of IL-6 in severe patients during the disease course. (medsci.org)
One of the investigators (S.S.Z.) obtained lymphocyte subsets on 25 of the patients before and during DMF treatment. (neurology.org)
Blood samples for further analyses were collected from patients in the third and sixth month of immunotherapy. (mdpi.com)
The frequency of CD4+CD25high in the peripheral blood of 62 cancer patients and 15 healthy donors was determined by flow cytometry. (nel.edu)
We provide evidence of an increased pool of CD4+CD25high in the peripheral blood of cancer patients, which may be related to immunosuppression and tumor progress in cancer patients. (nel.edu)
In order to examine the role of NFkappabeta in the pathophysiology of CFS, this study examines the production of NFkappabeta p50 in unstimulated, 10 ng/mL TNF-alpha (tumor necrosis factor alpha) and 50 ng/mL PMA (phorbolmyristate acetate) stimulated peripheral blood lymphocy tes of 18 unmedicated patients with CFS and 18 age-sex matched controls.

BACKGROUND: We have recently reported a strong association between organ specific autoimmune disease and idiopathic chronic cough and have suggested that cough may be caused by airway inflammation secondary to aberrant homing of activated lymphocytes to the lung. (ox.ac.uk)

Leukemia , lymphoma (Hodgkin and non-Hodgkin) and myeloma are the three major categories of blood cancer. (bdbiosciences.com)
