22 Possible Causes for Fainting Spells, Peripheral T Cells Decreased

  • Essential Hypertension

    RESULTS: Compared with non-H-type hypertensive patients, CD4 T-cell percentage in peripheral blood was significantly decreased in H-type hypertensive patients.[] Because of the increase of Hcy level, CD4 T-cell percentage decreased.[] […] serum creatinine, uric acid, total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were recorded and analyzed with T-cell[]

  • Food Allergy

    This causes low FOXP3 mRNA levels and markedly decreased protein expression in peripheral blood lymphocytes of affected patients.[] […] production of T cells.[] Numbers of CD4( )CD25( )FOXP3( ) regulatory T cells are extremely low, and the CD4( )CD25( ) T cells that are present exhibit little regulatory function.[]

  • Chronic Fatigue Syndrome

    […] ratio, indicating a T H 2 shift. 50 When peripheral blood mononuclear cells from CFS patients are stimulated in culture, increased IL-4 levels accompany a high T H 2/T H 1[] A well-studied and characteristic finding is an attenuated T H 1 response. 47 – 49 Some adolescents with CFS exhibit increased levels of IL-10 and a decreased IFN-γ/IL-10[] […] ratio. 51 Studies revealing decreases in T H 1 and T H 17 inflammatory mediators may begin to provide links to the declining neurocognitive function and depressed psychosocial[]

  • Parkinson's Disease

    Pathogenesis • Escape from regulatory control of Helper T cells directed against these antigens • Defective intraocular T cell regulation of B cellsDecreased helper to[] […] suppressor T cell ratios in aqueous and peripheral blood • Other mechanisms – Anterior chamber associated immune deviation – Auto retinal antibodies – Related to Demyelination[]

  • Rheumatoid Arthritis

    In healthy controls, there was a strong inverse correlation between age and TREC content of the peripheral blood CD4 T-cell pool, reflecting the acknowledged decrease in thymic[] In view of these data, we analyzed the proportion of naive and memory peripheral blood CD4 T cells in a cross-section of healthy controls and RA patients.[] We developed an assay based on real-time PCR to provide an accurate measure of TRECs in peripheral blood.[]

  • Graves Disease

    Notably, HLA-DR14, a known risk factor for GD in Japanese individuals and the decreased regulatory T-cell numbers that were seen in the pediatric case, may affect the early[] Central and peripheral tolerance and Th1 cells appeared to be associated with the pathogenesis of GD in 22qDS.[]

  • HIV Infection

    Highly active antiretroviral therapy results in a decrease in CD8 T cell activation and preferential reconstitution of the peripheral CD4 T cell population with memory rather[] Evans TG, Bonnez W, Soucier HR, Fitzgerald T, Gibbons DC, Reichman RC.[]

  • Viral Meningitis

    Moreover, negative PPD skin reaction and decreased peripheral lymphocyte and active T cell count were observed.[]

  • Guillain-Barré Syndrome

    The percentages of Th1 and Th17 cells in the CD4 T lymphocyte subsets were significantly decreased, whereas the Th2 and Treg cells were increased in patients after treatment[] In the peripheral blood from patients received LPE treatment, the levels of immunoglobulin, complement, monocytes and fibrinogen were significantly reduced.[]

  • Graft-versus-Host-Disease

    These cells induce allogeneic T cell death in response to interferon-γ, resulting in regulatory T cell expansion and immunosuppression.[] The fraction of these CD34 monocytes in peripheral blood inversely correlates with GVHD in patients, suggesting that expanding these cells before transplant may decrease the[]
