Functional Deficiency

5-Methyltetrahydrofolate (5-MTHF) is the predominant form of folate and a strong determinant of homocysteine concentrations. There is evidence that suboptimal 5-MTHF availability is a risk factor for cardiovascular disease independent of homocysteine. The analysis of folates remains challenging and is almost exclusively limited to the reporting of “total” folate rather than individual molecular forms. The purpose of this study was to establish the reference intervals of 5-MTHF in plasma and red cells of healthy adults who had been prescreened to exclude biochemical evidence of functional deficiency of folate and/or vitamin B12. Functional folate and vitamin B12status was assessed by respective plasma measurements of homocysteine and methylmalonic acid in 144 healthy volunteers, aged 19–64 years. After the exclusion of 10 individuals, values for 134 subjects were used to establish the upper reference limits for homocysteine (13 μmol/L females and 15 μmol/L males) and methylmalonic acid (430 nmol/L). Subjects with values below these cutoffs were designated as folate and vitamin B12replete and their plasma and red cell 5-MTHF reference intervals determined,N=126: 6.6–39.9 nmol/L and 223–1041 nmol/L, respectively. The application of these intervals will assist in the evaluation of folate status and facilitate studies to evaluate the relationship of 5-MTHF to disease.

Abstract A Jewish family in which Hb L Ferrara (α247 Asp → Gly β2) occurred is reported. Studies of some of the properties of this hemoglobin demonstrated that its oxygen equilibria, number of readily reactive-SH groups, and spectro-photometric tyrosine titration were indistinguishable from Hb A. Nevertheless, Hb LF was more unstable than Hb A at 55 C. The propositus had accelerated blood destruction although six other heterozygotes for Hb LF did not. A second defect in red cell enzymes or red cell lipids of the propositus was not demonstrable with the technics used but the possibility that the simultaneous occurrence of Hb LF and an otherwise "silent" red cell defect may lead to a hemolytic state remains an attractive explanation. The data provided by this family study did not permit a definite conclusion about the relationship of clinically evident hemolysis in the propositus to the presence of the abnormal hemoglobin.

The Relationship

Abstract Ultrathin sections of erythrocytosis parasitized by B. bacilliformis have been examined by electron microscopy. The study concerns three Oroya Fever patients whose blood smears showed B. bacilliformis predominantly in its coccoid form as parastizing over 70 per cent of the red cells. B. bacilliformis is termed as a bacterium in its structure and appears to lie not only on the host red cells but predominantly within them. Therefore, this organism might have the capacity to penetrate into the red cell. This finding does not change the basic concept regarding the mechanism of the anemia of Oroya Fever.

The Relationship

Abstract The plasma volume, red cell volume, or both were measured in 170 normal, anemic, or polycythemic subjects. For anemic subjects without a serum protein abnormality or splenomegaly, the relationship between hematocrit and red cell volume was linear and predictable. In patients with a serum monoclonal globulin on electrophoresis, the plasma voluem was significantly increased for the hematocrit in 30%, and the total blood volume was increased in 45%. The frequency of an elevated plasma volume was higher in patients with a markedly increased level of monoclonal protein. Reductions of abnormal proteins with chemotherapy were associated with declines in plasma volume. For a specific concentration, the serum viscosity was highest in patients with IgM proteins and lowest in patients with IgG globulins. Marked elevations in viscosity were noted only in sera with macroglobulinemia or with more than 5 g/dl of IgG or IgA globulins.
