Osteosclerotic myeloma.

A 49-year-old man with an osteosclerotic lesion of a thoracic vertebra had peripheral neuropathy, lymphadenopathy, and elevated serum alkaline phosphatase and monoclonal immunoglobulin levels in the cerebrospinal fluid. These findings, not usually seen in ""classical'' myeloma, have been noted in different combinations in the osteosclerotic variety.

Marked cyclic leukocytosis-leukopenia in chronic myelogenous leukemia.

A spontaneous oscillation of the white blood cell count was observed in a 58 year old man with chronic myelogenous leukemia (CML). Similar cyclic variations were noted in the platelet and reticulocyte counts with no apparent alterations in marrow cellularity to account for such changes. Since direct correlation was noted between white blood cells, platelets, and reticulocyte counts versus spleen size, it suggests that splenic hemopoiesis may be responsible for these cyclic changes. A possible inverse relationship between colony-stimulating factor (CSF) activity and the white blood cell count was noted, suggesting that CSF may be the humoral agent controlling granulocyte production. A direct correlation between the white blood cell count and serum unsaturated vitamin B12 binding capacity (UBBC) and lysozyme was also noted and further supports the concept that the latter two are measures of the granulocyte pool and metabolism. An inverse relationship between CSF activity and the UBBC suggests that these may be two different entities. Finally a modified form of standard chemotherapy may be effective in inducing remission in cases of CML with marked cyclic leukocytosis-leukopenia.

Hb Leslie, an unstable hemoglobin due to deletion of glutaminyl residue beta 131 (H9) occurring in association with beta0-thalassemia, HbC, and HbS.

A new unstable hemoglobin, Hb Leslie, has been observed in three generations of a Georgia family. The propositus, a 42-yr-old black veteran with hemolytic anemia and splenomegaly, has a hemoglobin variant with an electrophoretic mobility similar to that of hemoglobin F. The variant comprises about 85% of the total hemoglobin and was isolated by chromatography. Chemical analysis has identified the abnormality as a deletion of the glutaminyl residue in position 131 (H9) of the beta-chain. Deletion of this critical residue which participates in the alpha1beta1 contact causes decreased stability of the hemoglobin without significant changes in functional properties or morphologic abnormalities in the erythrocyte. Family studies revealed hemoglobin Leslie occurring in combination with beta0-thalassemia, HbS, and HbC. All persons with the various Hb Leslie combinations, including the propositus, have no clinical manifestations other than anemia. In some the anemia is fully compensated. There is no history of drug-associated hemolysis.
