13. Pharmacokinetic/pharmacodynamic relationships of FTY720 in kidney transplant recipients
FTY720 is a new and effective immunosuppressive agent, which produces peripheral blood lymphopenia through a lymphocyte homing effect. We investigated the relationship between the dose of FTY720 or blood concentration (pharmacokinetics, PK) and peripheral lymphopenia (pharmacodynamics, PD) in 23 kidney transplant recipients randomized to receive FTY720 (0.25

14. Correlation between cytokine serum levels, number of CD4+ T cells/mm³ and viral load in HIV-1 infected individuals with or without antiretroviral therapy
Seventy-nine HIV-1 infected patients were studied in three groups: Group G1 - 11 patients with no antiretroviral therapy; G2 - 40 patients undergoing antiretroviral therapy, 33 with only two nucleoside reverse transcriptase inhibitors (NRTI), and seven with two NRTI and one protease inhibitor (PI), all with viral load (VL) equal or higher than 80 copies of p

15. Multisite Comparison of CD4 and CD8 T-Lymphocyte Counting by Single- versus Multiple-Platform Methodologies: Evaluation of Beckman Coulter Flow-Count Fluorospheres and the tetraONE System
New analytic methods that permit absolute CD4 and CD8 T-cell determinations to be performed entirely on the flow cytometer have the potential for improving assay precision and accuracy. In a multisite trial, we compared two different single-platform assay methods with a predicate two-color assay in which the absolute lymphocyte count was derived by conventio

16. Hematological reference ranges among healthy Ugandans.
Reference values are essential for the interpretation of hematologic data in clinical practice and research studies. Symptom-free human immunodeficiency virus antibody-negative Ugandan adults (183 subjects, aged 15 to 74 years, 37.7% women and 62.3% men) were studied to establish hematological reference ranges. The central 95% areas under the distribution cu

17. Evaluation of a method for counting absolute numbers of cells with a flow cytometer.
We evaluated a method for performing absolute cell counts of lymphocyte populations with a flow cytometer. In this method, TruCount, test tubes that contain a known number of brightly fluorescent polystyrene beads are provided by the manufacturer. Whole anticoagulated blood is accurately pipetted into the tubes and mixed with fluorochrome-labeled monoclonal

18. Early diagnosis of severe combined immunodeficiency syndrome.
Infants with severe combined immunodeficiency syndrome (SCIDS) have a greatly improved prognosis if diagnosed and treated before they develop overwhelming infection. Clinical and laboratory data on 45 patients with SCIDS were retrospectively reviewed to assess the value of absolute lymphocyte counts in making an early diagnosis. Ninety infants matched for ag

19. Differential white cell counts by frequency distribution analysis of cell volumes
Absolute neutrophil and lymphocyte counts on peripheral blood can be made by analysis of the output from a Coulter particle counter, utilizing the difference in the relative cell volume between these two types of cell. A comparison has been made between the results obtained by volume analysis and those obtained by standard microscopical techniques in 10 norm

20. Normal values for peripheral blood white cell counts in women of four different ethnic origins.
Total and differential white cell counts were studied in 399 women living in the same community in Britain but drawn from four different ethnic groups. The groups were white (northern European), Indian, black (African and West Indian), and Oriental. The total white cell count and absolute neutrophil count were significantly lower in the black group than in e

21. Clinical field site evaluation of the FACSCount for absolute CD3+, CD3+ CD4+, and CD3+ CD8+ cell count determinations in Thailand.
The FACSCount flow cytometer absolute CD3+, CD3+ CD4+, and CD3+ CD8+ cell counts measured at a field site hospital laboratory in Thailand were compared to FACScan absolute counts obtained at a nearby research laboratory. Correlation coefficients for 208 samples were > or = 0.95. The FACSCount was accurate, and it was easier and less expensive to operate than

22. T and CR+ lymphocyte profile in leprosy and the effect of treatment.
Thymus-derived lymphocytes (T lymphocytes) and complement receptor-bearing lymphocytes (CR+ lymphocytes) were estimated by using erythrocyte rosettes and erythrocyte-antibody-complement rosettes as markers in untreated lepromatous and untreated tuberculoid patients and in healthy controls. Treated lepromatous cases were also investigated. Ten cases of untrea

23. Factors associated with Pneumocystis carinii pneumonia in Wegener's granulomatosis.
OBJECTIVE--To determine the factors associated with the occurrence of Pneumocystis carinii pneumonia (PCP) in Wegener's granulomatosis (WG). METHODS--We retrospectively compared a group of 12 patients with WG and PCP (PCP group), with 32 WG patients without PCP followed over the same period in the same centres (control group). RESULTS--The mean delay of onse

24. Reduction of peripheral blood lymphocytes in patients receiving gold therapy for rheumatoid arthritis.
Peripheral blood lymphocytes were monitored prospectively in 10 patients with rheumatoid arthritis (RA) receiving up to 1 g of sodium aurothiomalate. There was a significant fall in the absolute lymphocyte count from a mean +/- SEM of 1956 +/- 190/mm3 (1.956 +/- 0.19 X 10(9)/l) to 1232 +/- 210/mm3 (1.232 +/- 0.21 X 10(9)/l) (p less than 0.01). The number of
