L-tetramisole. Enhancement of human lymphocyte response to antigen.

The anthelminthic drug L-Tetramisole enhanced in vitro lymphocyte transformation of normal young adults in the presence of PPD, Candida or measles antigen. This enhancement occurred regardless of evident pre-existing immunity to the antigen used. The increase in stimulation obtained by the drug and antigen combined, beyond that by antigen alone, varied between 1-25 and 5-99 for all three antigens in fourteen cell donors. Lymphocyte transformation was induced in seven individuals by the drug alone and suppressed in two. In levamisole dose--response tests, the optimum dose for this in vitro effect in six donors was similar for the three antigens.

Immunity of Epstein-Barr virus in Hodgkin's disease preceded by infectious mononucleosis.

A patient who developed Hodgkin's disease four years after infectious mononucleosis had elevated serum antibody titres to Epstein-Barr virus and delayed hypersensitivity reactions to membrane antigens prepared from fresh autologous spleen, from spleen cells of another Hodgkin's patient, and from cell lines known to carry the Epstein-Barr virus genome. Additional studies in more lymphoma patients will be needed to determine the significance of the reactivity against tumour and virus-associated antigens which has been documented in this patient.

Iron status and pregnancy in a northern Canadian population: relationship to diet and iron supplementation.

To determine the extent of iron deficiency, the prognostic value of prenatal ferritin levels and the desirability of prenatal iron supplementation in the western Canadian arctic, dietary iron intake was determined in 171 women and ferritin levels determined in 121 women during pregnancy, 79 at delivery and 77 postnatally, as well as in 65 of their infants at birth and 74 postnatally. Iron deficiency (ferritin < 15 ng/ml) was present in 34% of women during the first two trimesters, 25% (20/79) at delivery and in 51.7% (15/29) of mothers and 31% (9/29) of infants beyond four months after delivery. Maternal follow-up ferritin levels correlated poorly with dietary iron intake but well with prenatal ferritin levels, which appeared to be good predictors of the effectiveness of supplementation. Mean infant follow-up ferritin levels were 105.6 +/- 115.2 ng/ml with, and 46.7 +/- 63.5 without maternal prenatal supplementation (p = 0.03); maternal, 45.5 +/- 40.9 ng/ml with, and 12.8 +/- 9.2 without (p < 0.001). Measurement of prenatal ferritin levels to determine risk of iron deficiency and routine prenatal iron supplementation are recommended.
