The Finnish leukaemia group: levamisole in maintenance therapy of acute myeloid leukemia in adults.

The Finnish Leukaemia Group has carried out a randomized, multicenter trial to study the effect of levamisole on the remission maintained with 6-mercaptopurine and methotrexate in acute myeloid leukaemia in adults. Levamisole was given on 3 consecutive days every 2 weeks. Twenty-five patients received only chemotherapy, while 26 patients received levamisole as well. The patients receiving levamisole showed significantly better remission duration than those given only chemotherapy (P = 0.033, Mantel's summary chi 2-text). There are four long term survivors in the levamisole group versus none in the chemotherapy group. The remissions have lasted 48-75 months.

Myasthenia gravis and monoclonal IgG gammopathy.

Monoclonal IgG gammopathy of the lambda light-chain type was detected in a 51-year-old woman who had unexplained fever, muscle fatigue, and myalgia. One year later, myasthenia gravis was diagnosed. There was no evidence of myelomatosis or other malignancy. On the assumption that her M-component (gammopathic paraprotein) was related to myasthenia, she was treated with melphalan and cyclophosphamide, but her clinical condition was not improved. Despite therapeutic trials of other agents and a time course of 6 years, the quantity of the M-component remained unchanged. Serum AChR antibody activity was not located in the paraprotein peak. The findings do not support a relationship between the M-component and myasthenia gravis.

Different surface glycoprotein patterns on human T-, B- and leukemic-lymphocytes.

We have labelled the exposed surface glycoproteins of human blood T- and B-lymphocytes and cells from patients with chronic lymphocytic leukemia by the galactose oxidase-tritiated sodium borohydride method. The labelled glycoproteins were separated by polyacrylamide slab gel electrophoresis and visualized by autoradiography. The T- and B-lymphocytes show different and characteristic surface glycoprotein patterns. The surface glycoprotein patterns of the leukemic cells differ from those of normal, non-malignant lymphocytes. A relationship between the altered surface glycoprotein pattern of leukemic cells and the expression of leukemia-associated antigens is discussed.
