Uniparental isodisomy is defined as the inheritance of two copies of the same parental chromosome and can result in defects when it produces homozygosity for a recessive mutation or in the presence of imprinting. We describe the detection of a chromosome 6 uniparental isodisomy in a 9 year old girl, discovered during a search for an HLA identical sib. HLA typing, erythrocyte phenotyping, and ge...

Immunophenotyping of acute leukemia using flow cytometry after density gradient separation (dg-sep) of mononuclear cells is the international gold standard. But destroying red cells by whole blood lysis (wb-lysis) after direct staining has found a broad usage. Both methods revealed congruent results in phenotyping of 26 cases of acute myeloid leukemias by testing CD4, CD7, CD11b, CD11c, CD13, C...
BACKGROUND The downregulation of blood monocyte HLA-DR expression also occurs in tissue infiltrative cells in a context of acute clinical inflammation, especially sepsis. This context favors the development of secondary infections and results from various mechanisms. Little is known about HLA-DR expression on bone marrow (BM) cells of the monocyte lineage, the source of circulating monocytes. T...
Background: Multiple Sclerosis (MS) is an autoimmune disease with impairment in function of central nervous system. Macrophages and dendritic cells play important roles in alleviating or progression of the disease. These cells can cause inflammation and damage to the myelin of nerve cells by realizing of harmful substances when these cells get matured. We studied the effect of Alternaria altern...

BACKGROUND Individuals infected with human immunodeficiency virus (HIV) have increased risk of cardiovascular events. It is unknown whether T cell activation and senescence, 2 immunologic sequelae of HIV infection, are associated with vascular disease among HIV-infected adults. METHODS T cell phenotyping and carotid ultrasound were assessed among 115 HIV-infected women and 43 age- and race/et...
OBJECTIVE Collagenous sprue (CS) is a rare form of small bowel enteropathy characterised by a thickened basement membrane and is, in most of the literature, reported as part of coeliac disease. Multiple treatment strategies are suggested in CS, but there is no standardised therapy. The aim of this series is to describe 4 cases of CS and to propose thioguanine (6-TG) treatment. DESIGN We revie...
The HLA class II (DRB1 and DQB1) associations with sarcoidosis have been studied by several groups but often without consistent results. In this paper, we consider the hypothesis that observed inconsistencies relate to distinct, genetically encoded disease phenotypes which differ in prevalence between centres. We therefore typed HLA-DRB1 and DQB1 in 340 UK, 139 Dutch and 163 Japanese sarcoidosi...
