Declining blood CD4(+) T-cell counts mark the progress of simian immunodeficiency virus (SIV) disease in macaques and model the consequences of untreated human immunodeficiency virus infection in humans. However, blood lymphocytes are only a fraction of the recirculating lymphocyte pool, and their numbers are affected by cell synthesis, cell depletion, and distribution among blood and lymphoid ...
Our most recent data indicate differences in the levels of pro-inflammatory cytokines (IL-1β, IL-17, and IL-6) and malondialdehyde (MDA), a stable end-product of lipid peroxidation in the plasma samples between HIV positive individuals with low CD4 T cell counts <200 mm(3) and HIV positive individuals with CD4 T cell counts between 200 and 300 mm(3) (ee). The data lend support and provide valua...
BACKGROUND Recent data suggest that lymphopenia is more prevalent than reported in relapsing-remitting multiple sclerosis (RRMS) patients taking dimethyl fumarate (DMF). OBJECTIVE The objective of this study was to investigate the effect of DMF on lymphocyte subtypes in RRMS patients with and without lymphopenia. METHOD A retrospective study compared lymphocyte subtypes in DMF-treated RRMS ...
BACKGROUND CD4 cell count is a key measure of HIV disease progression, and the basis of successive international guidelines for treatment initiation. CD4 cell dynamics are used in mathematical and econometric models for evaluating public health need and interventions. Here, we estimate rates of CD4 decline, stratified by relevant covariates, in a form that is clinically transparent and can be d...
OBJECTIVE To assess the immunosuppressive effect of R-CHOP in patients with B-cell lymphoma at 2 years. METHODS Parameters of humoral and cell-mediated immunity were assessed in 89 patients with diffuse large B-cell lymphoma or follicular lymphoma before and after 6-8 cycles of R-CHOP-14 or R-CHOP-21 regimen. RESULTS Data on pre- and posttreatment serum IgG (sIgG) levels were available for ...
Prior studies have shown that weight may impact immune cell counts. However, few data exist about the relationship of weight and immune cell counts among HIV-infected patients. We examined documented HIV seroconverters (mean window, 15.7 months) in a prospective U.S. Military HIV Natural History Study (1 January 1986 to 20 January 2010). We estimated the association of the time-updated body mas...
OBJECTIVE Detailed studies of correlation between HIV-M.tb co-infection and hierarchy declines of CD8+/CD4+ T-cell counts and IFN-γ responses have not been done. We conducted case-control studies to address this issue. METHODS 164 HIV-1-infected individuals comprised of HIV-1+ATB, HIV-1+LTB and HIV-1+TB- groups were evaluated. Immune phenotyping and complete blood count (CBC) were employed to...
Infection with human immunodeficiency virus (HIV) is characterized by a progressive depletion of CD4(+) T cells that parallels a dysfunction of the B cell compartment and a disturbed recognition of self-antigens. The relationship between T lymphocyte homeostasis and abnormalities in the selection of self-reactive B cells is not clear as yet. We have therefore compared repertoires of natural ant...
BACKGROUND Low CD4(+) T-cell counts are the main factor leading to clinical progression in human immunodeficiency virus type 1 (HIV-1) infection. We aimed to investigate factors affecting CD4(+) T-cell counts after triple-class virological failure. METHODS We included individuals from the COHERE database who started antiretroviral therapy from 1998 onward and who experienced triple-class viro...
BACKGROUND Strong T cell and antibody responses to human immunodeficiency virus (HIV), low virus production, and some genetic traits have been individually associated with nonprogression of HIV infection, but the best correlate with protection against disease progression remains unknown. METHODS We prospectively followed 66 untreated long-term nonprogressors and analyzed relationships between...
