- BACKGROUND: Thanks to a successful voluntary vaccination programme, measles, mumps and rubella are rare diseases in Sweden. Coverage among children 18 mo of age has been 99%, but the measles, mumps and rubella vaccination (MMR) has increasingly been questioned among parents. AIM: To study reasons why parents choose not to vaccinate their child against measles, mumps and rubella, and their opinions on vaccines and the diseases themselves. A secondary objective was to compare coverage at 18 mo of age based on parental report with the national statistics based on patient charts. METHODS: The official statistics were compared with patient charts for two birth cohorts in the city of Goteborg, Sweden. Out of these children born in 1995 and 1996, 300 unvaccinated and vaccinated children were identified. Their parents received a postal questionnaire assessing the parent's views on vaccines and childhood diseases. RESULTS: The documented vaccine coverage in this study was higher in 1995 and 1996 than official statistics indicated. The major reason, for both groups, for accepting respectively declining vaccination was strengthening the child's immune system. Parents with children unvaccinated against MMR were also more likely to have declined vaccination against diphtheria, polio, tetanus, Haemophilus influenzae and pertussis. One-third of the parents with a child unvaccinated against MMR had not yet made their final decision 3 y after the vaccine offer. Few parents, both with vaccinated and unvaccinated children, had acquired vaccine information from the Internet. Both groups believed that insufficient time was allocated for vaccine information and discussion at the Child Health Centre. CONCLUSION: Our study indicates that official statistics on MMR vaccination uptake underestimate the number of vaccinated children. Vaccine safety is a major concern for many parents and needs to be addressed by healthcare professionals at institutions offering paediatric vaccinations.

- AIM: To evaluate the efficacy of two different Swedish screening procedures for early detection of congenital cataracts in comparison with no screening. METHODS: Children born between January 1992 and December 1998 in Swedish regions with an established eye-screening routine procedure, diagnosed with congenital cataract, and operated on before 1 y of age, were included in a retrospective study. Age at referral and age at time of the operation were compared between regions using different screening procedures: screening in the maternity wards (Region 1), at the well-baby clinics (Region 2) and one region without any screening (Region 3). RESULTS: Seventy-two children were included in the study. Concerning early diagnosis and surgery, Region 1 differed significantly from Regions 2 and 3, which were more similar and were combined for further analysis. The difference in detected cases was greatest at 21 d of age (55% vs 18%; p < 0.001), but persisted even at 100 d of age (78% vs 64%; p < 0.02). Region 1 screening resulted in more and earlier cases detected than the other two regions (22 vs 15 per 100,000 births). In 72% of all cases, surgery was performed in response to referrals from either the maternity wards (36%), or the well-baby clinics (36%). However, half of the cases from the well-baby clinics were detected too late, i.e. at > 100 d. CONCLUSION: Eye screening in the maternity ward is preferable to well-baby clinic screening and to no screening at all, since it leads to early detection. Screening should also be performed routinely at well-baby clinics within the period when successful treatment is possible.

Specific IgE antibodies to peanut in western Sweden - has the occurrence of peanut allergy increased despite constant consumption?

Tidskriftsartikel (refereegranskat)abstract
- Background: Sensitization to peanut has seldom been investigated in Sweden. Therefore, all IgE-specific tests for peanut during a 5-year period were reviewed to study the relation between the levels of specific IgE antibody to peanut and age, sex, symptoms, and other atopic manifestations. Methods: All serum samples were analyzed for IgE antibodies to peanut in relation to sex, age, clinical reactions, and other food allergens. A subgroup was asked to answer a questionnaire about symptoms and atopic manifestations in relation to IgE antibody levels. Results: During the study period, 2417 tests were made for peanut. There was an increased prevalence of detectable IgE antibodies during the years studied. More than 80 individuals under 2 years of age were sensitized to peanut. In the subgroup, individuals with detectable IgE antibodies reported a shorter reaction time after eating peanuts than individuals with normal IgE antibody levels (P<0.05). Conclusions: The reaction pattern to peanuts in Sweden is similar to that in many other countries despite a reported steady and low consumption. The severity of symptoms was connected to age and IgE antibody level. Patients with normal or low IgE antibody levels were not always free of symptoms even though their risk of allergic symptoms was reduced.

Specific immunoglobulin E antibodies to peanut over time in relation to peanut intake, symptoms and age

- The clinical outcome of peanut allergy and some factors associated with development of peanut allergy remain unsolved. It has not been clarified to what extent peanut intake affects immunoglobulin (IgE) antibody formation in peanut sensitized individuals. The aim of the study was to investigate the development of peanut hypersensitivity in children and adolescents with specific IgE antibodies to peanut, using questionnaires and current serum tests and comparing it to information obtained 5-6 yr earlier, to investigate how peanut intake during this period related to subject age, IgE antibody levels and symptoms and to investigate what information this patient group was given at the time of diagnosis regarding avoidance of peanut related food. All patients with detectable peanut-specific IgE antibodies investigated during 1994-1996 deriving from two allergy laboratories in the western region of Sweden were traced and reinvestigated (n=132). A total of 111 subjects (63 with peanut allergy and 48 peanut sensitized) participated in the questionnaire. Eighty-six of them consented to be enrolled in a further interview and renewed testing of specific IgE antibody to peanut 5 yr later. All tests were done using the Pharmacia CAP system. Increased IgE antibody levels during follow-up was related to age; subjects 0-6 yr at initial test occasion were more likely to have higher IgE antibody class than the older individuals (p=0.018). Exposure to peanut during the study, i.e. 5-6 yr since diagnosis, did not seem to affect the result. During the follow-up period, 29 out of 86 (34%) increased their IgE antibody class. At the second test occasion the remaining subjects had similar (28%) or lowered (38%) levels of IgE antibodies. Exposure to peanut during follow-up was more common in subjects with IgE antibody class 1-3 compared to subjects with high value (> 3) at the initial test (p=0.003). Reported symptoms during follow-up were also more common in subjects with initially high IgE antibody value. Individuals with initially high IgE antibodies to peanut had been given more information about peanut allergy and cross-reacting allergens than other individuals. The subjects over 6 yr of age showed a decrease in peanut-specific IgE class over a 5-yr period. Together with the literature, our result suggest that follow-up and renewed testing is recommended, since there may be a change in IgE antibody classes and clinical sensitivity over time. Even in Sweden, with a low consumption of peanuts, the youngest individuals with peanut sensitization experienced a similar course of events that has been reported in other countries.
