Depressed PHA transformation and acute leukemia in macroglobulinemia.

Two out of fifty-three patients with macroglobulinemia developed acute leukemia following chemotherapy. The Phytohemagglutinin (PHA) Transformation Index performed prior to the appearance of acute leukemia was found to be markedly depressed in these two patients in comparison with ten other patients with macroglobulinemia. In addition, a clone with monosomy 7 was detected in one of the currently reported patients when the leukemic process became apparent. The cytogenetic analysis was normal in the same patient 48 months earlier, when macroglobulinemia was diagnosed. The low PHA Transformation Index and the chromosomal hypodiploidy are of interest and their clinical significance merits further investigation.

Benign cholestatic jaundice after nephrectomy for pyonephrosis and sepsis.

Severe benign postoperative intrahepatic cholestatic jaundice appeared immediately after nephrectomy in a patient with nephrolithiasis and septicemia. Convalescence was uneventful and no treatment was necessary. This diagnostic possibility should be considered whenever jaundice appears postoperatively for pyonephrosis and septicemia.

HLA antigens in genetic neutropenia of Yemenite Jews.

The HLA antigenic system was studied in Yemenite Jews with genetic neutropenia. No deviation in antigen frequency was observed when compared with matched controls from the same ethnic group. HLA antigen frequency and common haplotypes of the Yemenite Jews were found entirely different from those of the African blacks, known to have the same anomaly.

Pulmonary alveolar proteinosis associated with fanconi's anemia.

A 16-year old patient with Fanconi's anemia developed pre-leukemia and pulmonary infiltration which was found upon autopsy to be pulmonary alveolar proteinosis. The question whether the pulmonary alveolar proteinosis was due to the marked leukopenia and an eventual defective phagocytic ability of the leukocytes is raised.

Prolonged busulfan-induced remissions in chronic myeloid leukemia.

Two prolonged remissions were achieved in a patient with chronic myeloid leukemia by two short courses of busulfan treatment. The first remission lasted for 7 years; the second one lasts already 14 years. In the interval periods no treatment was administered.

De novo synthesis of purine nucleotides and metabolic availability of phosphoribosylpyrophosphate in leukemic leukocytes.

Among normal peripheral blood leukocytes, lymphocytes were found to contain most of the de novo purine synthesizing capacity. The rate of purine synthesis de novo was accelerated in leukocytes from patients with acute and chronic myelocytic leukemias, chronic monocytic leukemia, myelofibrosis and plasma cell leukemia, but was normal in most patients with chronic lymphocytic leukemia. The rate of de novo purine synthesis exhibited positive correlation with the percentage of immature cells in the leukocyte population. The metabolic availability of phosphoribosylpyrophosphate (PRPP) exhibited positive correlation with the state of de novo purine synthesis. These finding suggest that the accelerated rate of de novo purine synthesis and the increased metabolic availability of PRPP are characteristic properties of the immature leukemic granulocyte.

Migration inhibition factor activity in sera of patients with chronic lymphatic leukemia.

Migration inhibition factor (MIF) activity, expressed as a migration index, was studied in the sera of 48 chronic lymphatic leukemia (CLL) patients and 48 healthy controls. MIF activity was detected in the sera of 50% of the CLL patients. The medical condition of patients in advanced clinical stages (III and IV) and with detectable MIF activity was more stable (after 18-mo follow-up) than was that of the patients in advanced stages but without detectable MIF activity. No relationship was found between the clinical stage of the disease, absolute lymphocyte count, and MIF activity.
