Over a 4 month period, the medical records of 255 children with an age range of 6 months to 3 years and who had been admitted to the Cherbourg Hospital Department of Pediatrics were prospectively studied. Ninety-nine % had received BCG vaccination but only 71% had a positive skin test. Ninety-two % were vaccinated against diphtheria, tetanus, whooping cough and poliomyelitis and 61% against measles. Seventy-eight % of parents said that they had correctly administered vitamin D, at least up to 18 months of age. Seventy % of children were fed cow's milk during the second half of the first year and at least 35% had at least one hematological sign of iron deficiency. The promotion of routine immunizations as well as vaccination against rubella-mumps-measles seems to be desirable goals. There is a need for the widespread use of adapted milk formulas up to 1 year of age and for systematic iron supplementation of pregnant women and of infants presenting with evidence of iron deficiency or on cow's milk.

Restless legs syndrome (RLS) has been described in association with a number of conditions including iron deficiency, neuropathy and Parkinson's disease. Here we report a patient who developed RLS concurrent with the development of classic post-polio syndrome (PPS), 40 years after recovery from an episode of paralytic poliomyelitis. PPS is still frequently encountered in neurological practice, and clinicians should be aware of the possibility of associated RLS.

Background: Iron deficiency may impair adaptive immunity and is common among African infants at time of vaccination. Whether iron deficiency impairs vaccine response and whether iron supplementation improves humoral vaccine response is uncertain. Methods: We performed two studies in southern coastal Kenya. In a birth cohort study, we followed infants to age 18 mo and assessed whether anemia or iron deficiency at time of vaccination predicted vaccine response to three-valent oral polio, diphtheria-tetanus-whole cell pertussis-Haemophilus influenzae type b vaccine, ten-valent pneumococcal-conjugate vaccine and measles vaccine. Primary outcomes were anti-vaccine-IgG and seroconversion at age 24 wk and 18 mo. In a randomized trial cohort follow-up, children received a micronutrient powder (MNP) with 5 mg iron daily or a MNP without iron for 4 mo starting at age 7.5 mo and received measles vaccine at 9 and 18 mo; primary outcomes were anti-measles IgG, seroconversion and avidity at age 11.5 mo and 4.5 y. Findings: In the birth cohort study, 573 infants were enrolled and 303 completed the study. Controlling for sex, birthweight, anthropometric indices and maternal antibodies, hemoglobin at time of vaccination was the strongest positive predictor of: (A) anti-diphtheria and anti-pertussis-IgG at 24 wk (p = 0.0071, p = 0.0339) and 18 mo (p = 0.0182, p = 0.0360); (B) anti-pertussis filamentous hemagglutinin-IgG at 24 wk (p = 0.0423); and (C) anti-pneumococcus 19 IgG at 18 mo (p = 0.0129). Anemia and serum transferrin receptor at time of vaccination were the strongest predictors of seroconversion against diphtheria (p = 0.0484, p = 0.0439) and pneumococcus 19 at 18 mo (p = 0.0199, p = 0.0327). In the randomized trial, 155 infants were recruited, 127 and 88 were assessed at age 11.5 mo and 4.5 y. Compared to infants that did not receive iron, those who received iron at time of vaccination had higher anti-measles-IgG (p = 0.0415), seroconversion (p = 0.0531) and IgG avidity (p = 0.0425) at 11.5 mo. Interpretation: In Kenyan infants, anemia and iron deficiency at time of vaccination predict decreased response to diphtheria, pertussis and pneumococcal vaccines. Primary response to measles vaccine may be increased by iron supplementation at time of vaccination. These findings argue that correction of iron deficiency during early infancy may improve vaccine response.
