Serum levels of IgE in malignant lymphogranulomatosis.

Serum levels of IgE in malignant lymphogranulomatosis (Hodgkin's disease) were lowered in patients who had been intensively treated, without eosinophilic granulocytes, and in less advanced forms of the disease. High levels were observed in untreated patients with eosinophilic granulocytes in their peripheral blood, and in clinically advanced cases.

[M-component of serum formed by lambda-type Bence-Jones protein].

M-component in the serum composed of free light chains occurs rarely as evidenced by literature. In the investigations of the authors it was demonstrated that three M components obtained from patients with plasmocytoma were composed of free light chains type lambda. High concentration of low-molecular protein in serum was due, probably, to coexistent impairment of renal filtration. It is worth stressing that M component was a lambda-type chain which may explain the pathogenesis of renal failure caused by amyloidosis.

[Disorders in the conversion of fibrinogen to fibrin in patients with multiple myeloma].

A prolonged thrombin clotting time was found in 15 of 85 patients with multiple myeloma. Among those with abnormal clotting time in 9 cases (60.0%) the M protein was classified as IgG-lambda, in 1 (6.6%) as IgA-lambda, in 2 (13.3%) as IgG-kappa, and in 3 (20.3%) as IgA-kappa. There was no correlation between the prolongation of thrombin time and occurrence of bleeding. The reptilase clotting time was parallel to the thrombin time. The addition of calcium chloride partially corrected both clotting times. The isolated M proteins IgG-lambda and IgG-kappa from patients with prolonged thrombin time at the concentration of 25-50 mg/ml inhibited the polymerization of fibrin monomers but had no effect on the amidolytic and proteolytic action of thrombin.

[IgM monoclonal gammopathy in plasmacytic neoplasms].

In 331 patients with the diagnosis of multiple myeloma in 4 cases proliferation of plasma cells was associated with synthesis of a monoclonal IgM. In 3 of these cases coexistence was noted of features typical of multiple myeloma and Waldenström's macroglobulinaemia. In the clinical picture in two of these cases sings of blood hyperviscosity prevailed. These patients showed impairment of plasma clotting factors. The count of T and B cells in blood and the adherence and phagocytic activity of monocytes were not abnormal. The ultrastructural pattern of plasma cells in bone marrow was similar to that observed in classical cases of IgG or IgA multiple myeloma. In one case of lymphoplasmocytic proliferation with leucocytosis over 100 x 10(9)/l immunoelectroscopic examination of bone marrow cells demonstrated a formidable accumulation of the heavy chain of mu immunoglobulin in the cytoplasm of lymphoplasmacytes. In the serum and urine no monoclonal protein was found. In this case compression of vertebral bodies Th7 and L2 occurred.
