Evidence for a shift from a type I lymphocyte pattern with HIV disease progression. Hemophilia Growth and Development Study

by

Abstract

Whether a shift from a type I (cell mediated) immune profile occurs with progressive HIV-related immune dysfunction is a matter of heated debate.

We analyzed data for 333 HIV antibody-positive (HIV+) and -negative (HIV-) hemophilic children/adolescents, to examine whether the relationships among immunologic parameters and vaccine-related serology supported a shift with advancing HIV infection.… Read more

Immune and serologic profiles of HIV-infected and noninfected hemophilic children and adolescents. Hemophilia Growth and Development Study Group

by

Abstract

OBJECTIVES: To assess relationships among the effects of HIV on hemophilic children and adolescents’ immunologic parameters and vaccine-related serology.

METHODS: We analyzed data from extensive baseline immunologic evaluations of 207 HIV antibody-positive (HIV+) and 126 HIV antibody-negative (HIV-) hemophilic children and adolescents.… Read more

Transient antibody deficiency and abnormal t-suppressor cells induced by phenytoin

by

Abstract

The lack of normal  B-cell  differentiation in patients with acquired or congenital antibody  deficiency may reflect abnormalities inherent in cells of B-lymphoid  lineage or may  involve abnormalities of regulatory (suppressor) cells. Circulating suppressor T cells,  which interfere with IgM secretion in a plaque-forming-cell assay, have been found in 60 per cent of these patients,  but their role in the pathogenesis of the disease is unclear. … Read more
