Igs contain unique portions, collectively termed idiotypes (Id), that can be recognized by the immune system. Id expressed by tumor cells in B-cell malignancies can be regarded as tumor-specific antigens and a target for vaccine immunotherapy. We have started a vaccination trial in multiple myeloma (MM) using Id-specific proteins conjugated to keyhole(More)
We report a case of Philadelphia chromosome (Ph) positive thrombocythemia with a complex translocation. G-banding analysis showed the predominant karyotype to be 46,XX,t(9;15;22). Southern blot analysis revealed a rearrangement within the breakpoint cluster region on chromosome 22 similar to findings in chronic myeloid leukemia. These data suggest the(More)
Multiple myeloma (MM) is characterized by the expansion of terminally differentiated plasma cells. It is still uncertain whether the clonogenic fraction is confined to the plasma cell or pre-plasma cell compartment. We examined the immunoglobulin (Ig) rearrangement of myeloma heavily infiltrated bone marrow cells with a probe from the heavy chain J region(More)
PURPOSE Polyclonal IgG, IgA, and IgM immunoglobulins are often decreased in sera of patients with multiple myeloma (MM), whereas very few data are available on polyclonal IgE levels. We have determined IgE levels in a large series of MM patients at diagnosis and subjects with monoclonal gammopathy of undetermined significance (MGUS) and correlated IgE(More)
Retinoic acid has been shown to induce growth inhibition in a variety of cell types including human myeloma cell lines. Bone marrow plasma cells from 31 multiple myeloma (MM) patients were cultured to investigate the activity of 13-cis-retinoic acid (cRA), all-trans-retinoic acid (tRA), interferon-alpha (IFN-alpha), interferon-gamma (IFN-gamma), and(More)
The paper describes a case of mixed cryoglobulinemia with a double serum monoclonal component. The serum immunofixation revealed that a monoclonal component was IgG lambda while the other was positive for antisera anti-IgM, anti-k and anti-lambda even if the EP proved monoclonal. Resuspended cryoglobulins had the same electrophoresis pattern and the same(More)
In this study we investigated serum neopterin levels in 73 multiple myeloma (MM) patients (63 determinations at diagnosis, 58 in remission, and 35 at relapse), in 56 monoclonal gammopathies of undetermined significance (MGUS), and in 70 normal controls. Median neopterin level was 5.3 nmol/l in normal controls, 6.8 nmol/l in MGUS, and 10.7 nmol/l in MM(More)
Recurrent nasal polyposis is one of the most common unsolved problem in clinical rhinology. In the last few years a great number of histopathological, immunohistochemical and immunological studies on nasal polyps have been carried out by several Authors. Notwithstanding this, the aetiology of these formations still remains unknown. Many data suggest that(More)
Long-term bone marrow culture (LTBMC) was evaluated as a purging procedure in the murine plasmocytoma MOPC-315s system. MOPC-315s cells injected in Balb-c mice rapidly proliferate both in marrow and spleen, where macroscopic tumor colonies develop. A linear relationship between the number of injected cells and spleen colonies was observed, consistent with(More)
Pathological modification in secretory IgA values as well as in circadian rhythms were found in tracheotomized patients in both nasal and tracheo-bronchial secretions. The protective role of the mucosal immune system in addition to the frequency of severe infectious respiratory diseases in laryngectomized patients justifies the efforts of clinicians to(More)
