Autoimmune lymphoproliferative disorders, including autoimmune lymphoproliferative syndrome (ALPS) and Dianzani autoimmune lymphoproliferative disease (DALD), are inherited defects of the Fas apoptotic pathway characterized by lymphoid accumulation and autoimmune manifestations. We report the molecular, clinical, immunologic features and the long-term progress of 31 patients. Four carried Fas g...

BACKGROUND AND PURPOSE Accurate discrimination of orbital lymphoma from benign orbital lymphoproliferative disorders is crucial for treatment planning. We evaluated MR imaging including DWI and contrast-enhanced MR imaging for differentiating orbital lymphoma from benign orbital lymphoproliferative disorders. MATERIALS AND METHODS Forty-seven histopathologically proved orbital lymphoprolifera...

The association between Epstein-Barr virus subtype, human leukocyte antigen class I alleles, and the development of posttransplantation lymphoproliferative disorder was examined in a group of 25 bone marrow transplant recipients. A highly statistically significant correlation was observed between the human leukocyte antigen B51 allele and development of posttransplantation lymphoproliferative d...

background with the advent of highly effective anti-hepatitis c virus (hcv) drugs, efforts to identify infected cases, high-risk groups, and associated risk factors have become the focus of current control measures. objectives to determine the prevalence of the hcv antibody among diabetics and patients with lymphoproliferative disorders (lpd) who presented to the outpatient clinics of a univers...

introduction: quantification of epstein - barr virus (ebv) in peripheral blood mononuclear cells (pbmnc) of allogenic bone marrow transplant (bmt) recipients is important because ebv-associated posttransplant lymphoproliferative disease (ptld) can occur after transplantation due to immunosup-pression therapy. methods: to this end we chose real-time pcr using taqman probe. for the standard curve...

OBJECTIVE To evaluate the immune response in Peruvian children following measles vaccination. METHODS Fifty-five Peruvian children received Schwarz measles vaccine (about 10(3) plaque forming units) at about 9 months of age. Blood samples were taken before vaccination, then twice after vaccination: one sample at between 1 and 4 weeks after vaccination and the final sample 3 months post vaccin...

The practical importance of finding a morphologically benign lymphoid aggregate in the bone marrow of patients without known lymphoproliferative disease was assessed in 786 consecutive patients who had had 951 iliac crest bone marrow biopsies performed. Of these, 430 patients known to have lymphoproliferative disease at the time of biopsy were excluded. Of 356 patients, 86 (aggregate group) had...

BACKGROUND Inherited defects decreasing function of the Fas death receptor cause autoimmune lymphoproliferative syndrome and its variant Dianzani's autoimmune lymphoproliferative disease. Analysis of the lymphocyte transcriptome from a patient with this latter condition detected striking over-expression of osteopontin and tissue inhibitor of metalloproteinases-1. Since previous work on osteopon...
