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.[ncbi.nlm.nih.gov] Because of the increase of Hcy level, CD4 T-cell percentage decreased.[ncbi.nlm.nih.gov] […] serum creatinine, uric acid, total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were recorded and analyzed with T-cell[ncbi.nlm.nih.gov]

  • Food Allergy

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

  • 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[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov] […] 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[ncbi.nlm.nih.gov]

  • 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[slideshare.net] […] suppressor T cell ratios in aqueous and peripheral blood • Other mechanisms – Anterior chamber associated immune deviation – Auto retinal antibodies – Related to Demyelination[slideshare.net]

  • 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[bloodjournal.org] 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.[bloodjournal.org] We developed an assay based on real-time PCR to provide an accurate measure of TRECs in peripheral blood.[bloodjournal.org]

  • 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[ncbi.nlm.nih.gov] Central and peripheral tolerance and Th1 cells appeared to be associated with the pathogenesis of GD in 22qDS.[ncbi.nlm.nih.gov]

  • 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[hivinsite.ucsf.edu] Evans TG, Bonnez W, Soucier HR, Fitzgerald T, Gibbons DC, Reichman RC.[hivinsite.ucsf.edu]

  • Viral Meningitis

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

  • 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[ncbi.nlm.nih.gov] In the peripheral blood from patients received LPE treatment, the levels of immunoglobulin, complement, monocytes and fibrinogen were significantly reduced.[ncbi.nlm.nih.gov]

  • Graft-versus-Host-Disease

    These cells induce allogeneic T cell death in response to interferon-γ, resulting in regulatory T cell expansion and immunosuppression.[stm.sciencemag.org] 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[stm.sciencemag.org]
