Relationship of pertussis immunization to the onset of neurologic disorders: a retrospective epidemiologic study.

A retrospective epidemiologic study examining the relationship of the time of onset of neurologic disorders with the time of pertussis immunization in two cohorts of children who received pertussis immunization at different ages is reported. Before April 1970, children in Denmark were vaccinated with diphtheria and tetanus toxoids with pertussis vaccine at 5, 6, 7, and 15 months of age. Since 1970, children were given monovalent pertussis vaccine at 5 and 9 weeks and at 10 months of age. A total of 554 cases of epilepsy with onset between 28 days and 24 months of age were reviewed, 286 from the 1967-1968 period and 268 from the 1972-1973 period. There was no relationship between the age of onset of epilepsy and the scheduled age of administration of pertussis vaccine. A total of 2199 children with febrile seizures were reviewed, 830 from the 1967-1968 period and 1369 from the 1972-1973 period. There was a statistical association between first febrile seizures and the scheduled age of administration of pertussis vaccine (p = 0.004). No relationship between pertussis immunization and the occurrence of central nervous system infections was noted.

Relationship of pertussis immunization to the onset of epilepsy, febrile convulsions and central nervous system infections: a retrospective epidemiologic study.

A change in the pertussis immunization schedule in Denmark allowed a retrospective study examining the relationship of the time of onset of selected neurologic disorders with the time of pertussis immunization in two core cohorts of children. Records of 2,199 children with febrile seizures were reviewed and a significant association between first febrile seizures and the scheduled age of pertussis immunization was noted (p = 0.004). The occurrence of epilepsy and CNS infections did not appear to be related to the time of pertussis immunization.

Effect of eicosa-5, 8, 11, 14-tetraynoic acid on fatty acid composition of selected organs in the rat.

Eicosa-5, 8, 11, 14-tetraynoic acid or archidonic acid or no supplement (controls) was given orally to rats maintained on a fat free diet and the fatty acid composition of total lipids of several organs determined. No changes were noted in the total fatty acid concentrations of the organs examined in the various groups. A decrease in the amount of arachidonic acid, 22:4omega6 and 22:5omega 6 (as percent of total fatty acids), and an increase in the amount of 20:3omega6 and linoleate were observed in total lipids of several organs. In the group receiving the arachidonate supplement, there was less linoleate and 20:3omega 6 and more archidonate than in the controls. Both eicosa-5, 8, 11, 14-tetraynoic acid and arachidonate supplements resulted in a decrease in 20:3omega9 in most organs studied. Generally, the most marked changes were seen in liver but, of the other organs examined (heart, kidney, testis, brain, and adrenals), only the adrenals failed to show any significant differences between the controls and each of the two supplemented groups. Although the experimental conditions preclude conclusive interpretation of the changes observed, it is suggested that eicosa-5, 8, 11, 14-tetraynoic acid was effective in inhibiting the conversion of linoleate to archidonate and the conversion of arachidonate to 22:4 and 22:5.
