Serial measurements of beta-2-microglobulin in plasma correlates with white blood cell counts and haptocorrin in chronic myeloid leukemia.

The fate of beta-2-microglobulin was investigated in 17 patients with chronic myeloid leukemia by correlation analysis of the plasma concentration and various clinical measurements. The plasma concentration of beta-2-microglobulin correlated individually with white blood cell count, differential counts of band and segmented neutrophils, metamyelocytes and myelocytes, and haptocorrin concentration during the clinical course (p less than 0.002). The neutrophil granulocytes from the differential stage of myelocytes appears to be a major source of beta-2-microglobulin in chronic myeloid leukemia, and our results suggest that beta-microglobulin is is contained within the specific granules or is liberated from the plasma membranes synchronously with degranulation of neutrophils.

Acute promyelocytic leukemia with t(15;17) and t(2;17;15).

Cytogenetic examination in a case of acute promyelocytic leukemia (FAB-M3) demonstrated a stem line with t(15;17) and a side line with t(2;17;15). This observation indicates either clonal evolution from the standard translocation or a de novo complicated translocation. Previous cases with three-way translocations in acute promyelocytic leukemia have been reviewed. Three-way translocations seem to occur with similar frequency in M2 and M3 types of acute myeloid leukemia and in chronic myelocytic leukemia.

Lactic acid concentration and acid-base balance in cerebrospinal fluid: observations of diagnostic importance in non-Hodgkin lymphoma.

Measurements of lactic acid concentration and gas analysis were performed in lumbar cerebrospinal fluid from 36 patients without malignant central nervous system involvement and four patients with meningeal dissemination of non-Hodgkin lymphoma. The upper lactic acid concentration in controls of 2.48 mmol/l was exceeded in all four patients, also in cases with low blast counts and normal protein and glucose content. The pH, pCO2, pO2 and standard bicarbonate concentration in spinal fluid of patients with meningeal dissemination in non-Hodgkin lymphoma did not show significant differences compared with other patients and controls. Determination of the lactic acid concentration in cerebrospinal fluid add information, relevant to the diagnosis of meningeal involvement in non-Hodgkin lymphoma.

Measurement of beta-2-microglobulin in serum and plasma by an enzyme-linked immunosorbent assay (ELISA).

A simple technique for the measurement of beta-2-microglobulin (beta 2M) in serum was developed. The method was designed as a sandwich technique using rabbit anti-human antibodies, employing commercially available reagents in an enzyme linked immunosorbent assay (ELISA). The assay was of high specificity, sensitivity, accuracy and reproducibility. beta 2M in serum was strongly correlated with age (p less than 0.005), but independent of sex. Values in heparin and citrate plasma were significantly lower than in serum (p less than 0.001), whereas values in serum and EDTA plasma were similar. Release of beta 2M from normal blood cells was not observed in vitro before the test procedure. An excellent correlation between the results obtained in the ELISA and a RIA was demonstrated (rS = 0.99, p less than 0.0001).

Measurement of beta-2-microglobulin in human cerebrospinal fluid by ELISA technique.

This study introduces an enzyme-linked immunosorbent assay for measurement of beta-2-microglobulin in human cerebrospinal fluid. The concentration of beta-2-microglobulin in cerebrospinal fluid correlated with the age (p less than 0.001) of a control group of 40 subjects, probably reflecting age-related processes in the central nervous system. The reference interval of beta-2-microglobulin was considered to be 0.62-3.28 mg/1. Results obtained with various CNS disorders demonstrated that estimation of beta-2-microglobulin in cerebrospinal fluid add diagnostic information. The concentration of beta-2-microglobulin may increase without simultaneous aberrations in the content of protein, glucose and white blood cells.

Non-Hodgkin malignant lymphomas and Hodgkin's disease in first-degree relatives. Evidence for a mutual genetic predisposition?

The occurrence of malignant lymphomas in 3 siblings is described. The cases include the first report of Hodgkin's disease and non-Hodgkin malignant lymphoma in dizygotic twins. Another remarkable feature was the development of malignant lymphoma, when the siblings were at the same age. Although a transmissible agent or environmental factors cannot be excluded in this family, our observations may suggest a mutual genetic predisposition in Hodgkin's disease and non-Hodgkin malignant lymphoma.

Progressive multifocal leucoencephalopathy in Hodgkin's disease.

A case of progressive multifocal leucoencephalopathy in a 43-year-old man with Hodgkin's disease is presented. 17 similar cases from the literature are reviewed. Clinical implications of sex-ratio, age-distribution, diagnostic procedures and clinical course are discussed. Special attention is paid to the distribution of cases correlated to the lapse of time between diagnosis of Hodgkin's disease and symptoms of progressive multifocal leucoencephalopathy, indicating progressive multifocal leucoencephalopathy to be either a dormant infection, activated by Hodgkin's disease, or a haphazard complication. Both possibilities could be due to an impaired cell-mediated immune response.

Acute lymphocytic leukaemia with t(4;11): a clinical subentity.

5 cases of ALL are reported with a t(4;11) chromosomal rearrangement, and 31 cases, investigated before therapy, are reviewed. The (4;11) translocation characterizes a subentity of ALL having the following main features, as compared with ALL in general: 1) Excessively poor prognosis, with a median survival of 6 months despite high remission rates. 2) Low median age of 10 months in children. 3) CNS involvement apparently occurs more frequently. 4) Median WBC is 12 times higher in adults and children, median per cent of blasts in blood 1.5 times higher in adults and 1.8 times higher in children. 5) Splenomegaly is present more frequently. 6) Surface markers are non-B, non-T. The incidence of t(4;11) in ALL varies greatly in the series published so far, from 0.04% to 12%.

The carpal tunnel syndrome and amyloidosis. A clinical and histological study.

Twenty-six non-randomized patients with carpal tunnel syndrome are presented. It is documented that three out of four patients may be diagnosed pre-operatively by five or more clinical parameters. All patients were screened for amyloidosis in biopsies from the carpal tunnel. One patient presented amyloid deposits in the transversal carpal ligament. The importance of macro- and microscopic findings in the carpal tunnel inclusive local amyloidosis for the pathogenesis of the carpal tunnel is discussed. It is concluded that provided systemic amyloidosis is not suspected, screening for amyloidosis may have diagnostic interest, however without therapeutic consequences and therefore unnecessary.

Antibodies to common viruses in sera from patients with multiple myeloma.

The results of screening for antibodies against rubella, morbilli, mumps, herpes simplex, rota and Epstein-Barr virus in serum from patients with multiple myeloma are reported. Antibodies against herpes simplex virus were found in all samples, present in high titres in most samples. Antibody titres against the other five viruses were generally low. A possible association of common virus infections and myelomatosis is discussed.

Cancer diagnostic test of Field and Caspary: Part I. Spontaneous aggregation of lymphocytes in saline suspension is blocked by albumin and histone in normals but not in various disease states: the lymphocyte aggregation blocking test.

A blood test is described which is often positive in diverse disease states. In this test washed patient lymphocytes are incubated with histone or albumin. Early aggregation indicates that the patient might have inflammatory, malignant, or other disease, while absence of aggregation is the pattern found in normals. The test is called the lymphocyte aggregation blocking (LAB) test. Positive results when testing cancer patients were 86%, normals 14%, and non-malignant hospitalized patients were 50%. Lymphocyte aggregation was not an active process mediated by added protein. All washed lymphocyte suspensions will aggregate in the test conditions, whether, from normals, cancer or non-cancer patients if no protein is added. Normals' lymphocyte suspensions are prevented from aggregating by the added histone or albumin.
