Pertussis infection has been suspected to be a potential causal factor in the development of atopic disease because of the effect of pertussis immunization on specific IgE antibodies. Although several studies found a positive association between pertussis infection and atopic disorders, this relationship has not yet been studied in a population stratified by vaccination status. To assess the association between pertussis infection and atopic disorders in pertussis-unvaccinated children and in pertussis-vaccinated children. Using data from a previously conducted study on the relationship between the diphtheria-tetanus-pertussis-(inactivated) poliomyelitis vaccination in the first year of life and atopic disorders, the study population of 1872 8-12 yr old was divided into children pertussis-unvaccinated and children pertussis-vaccinated in the first year of life. Within each group, the association between pertussis infection and atopic disorders (both as reported by the parents) was assessed. In the unvaccinated group, there were no significant associations between pertussis infection and atopic disorders. In the vaccinated group, all associations between pertussis infection and atopic disorders were positive, the associations with asthma [odds ratio (OR) = 2.24, 95% confidence interval (CI(95%)): 1.36-3.70], hay fever (OR = 2.35, CI(95%): 1.46-3.77) and food allergy (OR = 2.68, CI(95%): 1.48-4.85) being significant. There was a positive association between pertussis infection and atopic disorders in the pertussis vaccinated group only. From the present study, it cannot be concluded whether this association is causal or due to reverse causation.

BACKGROUND: Early childhood immunizations have been viewed as promoters of asthma development by stimulating a T(H)2-type immune response or decreasing microbial pressure, which shifts the balance between T(H)1 and T(H)2 immunity. OBJECTIVE: Differing time schedules for childhood immunizations may explain the discrepant findings of an association with asthma reported in observational studies. This research was undertaken to determine whether timing of diphtheria, pertussis, tetanus (DPT) immunization has an effect on the development of childhood asthma by age 7 years. METHODS: This was a retrospective longitudinal study of a cohort of children born in Manitoba in 1995. The complete immunization and health care records of cohort children from birth until age 7 years were available for analysis. The adjusted odds ratio for asthma at age 7 years according to timing of DPT immunization was computed from multivariable logistic regression. RESULTS: Among 11, 531 children who received at least 4 doses of DPT, the risk of asthma was reduced to (1/2) in children whose first dose of DPT was delayed by more than 2 months. The likelihood of asthma in children with delays in all 3 doses was 0.39 (95% CI, 0.18-0.86). CONCLUSION: We found a negative association between delay in administration of the first dose of whole-cell DPT immunization in childhood and the development of asthma; the association was greater with delays in all of the first 3 doses. The mechanism for this phenomenon requires further research.
An anthroposophic lifestyle, where antibiotics, antipyretics, and vaccinations are restricted, was associated with a lower prevalence of atopy in a Swedish study of 295 children ages 5-13. Because this lifestyle includes some factors common decades ago, these results "may help to explain the recent increase in atopy," the investigators said. Atopy, determined by skin prick and blood tests, was 38% lower among children from anthroposophic families. Two-thirds of these children had had the measles, and 63% ate spontaneously fermented vegetables containing live lactobacilli vs. 4.5% of controls. Some infections, such as measles, and higher levels of intestinal lactobaccilli have been associated with less atopy, the authors said (Lancet 353:1485-88, 1999).

"Is infant immunization a risk factor for childhood asthma or allergy?" (Epidemiology, vol. 8, no. 6, November 1997): "Results of the Christchurch Health and Development Study, conducted by a team of New Zealand researchers, found a greater rate of asthma and allergy episodes among immunized children The comparison produced similar results at ages five and 16, and the discrepancy does not appear to result from use of health services, ethnicity, socioeconomic status, or parental atopy or smoking."

"Cases more often than controls reported suffering from asthma and allergies The observed association between asthma and epiglottitis is novel and deserves further investigation."

A new study in the Journal of Manipulative and Physiological Therapeutics1 supports the findings of three previous studies that children who receive diphteria-tetanus-pertussis (DTP) or tetanus vaccines are more likely to have a "history of asthma" or other "allergy-related respiratory symptoms." The study reviewed data from the Third National Health and Nutrition Examination Survey, which was conducted by the National Center for Health Statistics from 1988 to 1994. The survey data included interviews (by proxy with parents) of 13,944 infants, children and adolescents (2 months through 16 years old). http://www.chiroweb.com/archives/18/07/05.html

ABSTRACT: BACKGROUND: Continued surveillance, and detailed investigation of direct and indirect effects of conjugated vaccines and risk factors for invasive H.influenzae serotype B (Hib) disease in the vaccine era are important. METHODS: 143 cases with invasive disease between 1991 and 1993 aged 2-16 years were selected retrospectively from a large incidence trend study. Controls (n = 336) were recruited from local vital registries and matched to cases for age, gender, and residence. Hib vaccination histories among study subjects and their siblings and other sociodemographic variables were obtained by questionnaires completed by the parents of these children. Adjusted odds ratio (OR) estimates were calculated by conditional logistic regression analysis. RESULTS: Most vaccinated subjects had received the Polysaccharide- Diphtheria Toxoid vaccine and estimated vaccine efficacy was high (95%; 95% confidence interval [CI] 60-99%). Also, the results suggested that protection afforded by vaccination against Hib extended to the family members of vaccinated children. School attendance was found to be protective against invasive Hib disease (OR:0.33; CI:1.2-14.4). Cases more often than controls reported suffering from asthma and allergies (OR:4.8; CI:1.2-19.4). CONCLUSIONS: Post-licensure vaccine efficacy is high among children > or = 2 years of age. The observed association between asthma and epiglottitis is novel and deserves further investigation.

ABSTRACT: To determine the efficacy of a mucosal vaccine against nontypeable Haemophilus influenzae (NTHi), mice were immunized nasally, orally, intratracheally, or intraperitoneally with NTHi antigen together with cholera toxin. Antigen-specific IgA antibody titers in nasal washes and the numbers of antigen-specific IgA-producing cells in nasal passages showed the greatest increases in mice immunized nasally. Cytokine analysis showed that interferon-gamma, interleukin (IL)-2, IL-5, IL-6, and IL-10 were induced by nasal immunization, suggesting that Th2- and Th1-type cells were generated. Furthermore, bacterial clearance of a homologous strain of NTHi from the nasal tract was significantly enhanced in the nasal immunization group. These findings suggest that nasal immunization is an effective vaccination regimen for the induction of antigen-specific mucosal immune responses, which reduce the colonization of NTHi in the nasal tract.

levels. Int Arch Allergy Appl Immunol 1980;61(3):352-7 PMID: 6153378 UI:
ABSTRACT: Histidine decarboxylase activity and histamine levels of peritoneal mast cells were enhanced 4 days after intraperitoneal Haemophilus influenzae vaccination of rats. Incubation of the cells with propranolol (3.4 x 10(-4) M) resulted in histamine release and an increased histidine decarboxylase activity. Histidine decarboxylase activity and histamine release were more increased in the presence of propranolol in mast cells obtained from H. influenzae-vaccinated rats. An increased mediator release is also suggested by the increase of the number of peritoneal eosinophils. These data might explain the earlier observed enhanced plasma and lung histamine levels in H. influenzae- vaccinated rats.

vaccination of mice and rats with Haemophilus influenzae and Bordetella pertussis as
models of atopy. Clin Exp Pharmacol Physiol 1979 Mar-Apr;6(2):139-49 PMID: 311260
ABSTRACT: 1. Rats and mice were vaccinated with Haemophilus influenzae in different vaccination schedules whereafter blood eosinophils were counted. In rats a single vaccination resulted in a dose-dependent effect on the blood eosinophil count in a pattern comparable with that after Bordetella pertussis vaccination. In a long-term vaccination schedule (five times a week for 5 weeks) rats developed a constant eosinophilia. In mice a single vaccination resulted in an eosinopenia of a consistent pattern which differed from the response after Bordetella pertussis vaccination; in a long-term vaccination schedule, eosinophilia was evoked for a period of about 13 days. 2. Thirty minutes after an adrenaline injection in vaccinated rats and mice with Haemophilus influenzae, hyperglycaemic and eosinophilic responses were measured. The eosinophilic response after adrenaline was inhibited in both species; the hyperglycaemic response in rats was unaltered, in mice the response was slightly but significantly (P less than 0.05) decreased. 3. The sensitivity to several drugs was tested in mice, 5 days after vaccination with Haemophilus influenzae or Bordetella pertussis. Haemophilus influenzae vaccination reduced the isoprenaline sensitivity and increased the noradrenaline sensitivity. Bordetella pertussis vaccination reduced the isoprenaline sensitivity while the sensitivity to histamine and adrenaline was raised. 4. The Haemophilus influenzae vaccinated experimental animal provides a model that is possibly more related to human atopy than the Bordetella pertussis vaccinated animal.

ABSTRACT: To determine whether Haemophilus influenzae could be a factor in human atopy its effects were studied on the (para-)Sympathic Cyclic nucleotide-histamine axis in rats. Haemophilus influenzae vaccination induced changes in the cholinergic system compatible with higher cyclic GMP levels and enhanced histamine release. The authors suggest an involvement of the cholinergic system in Haemophilus influenzae vaccination effects.

ABSTRACT: Bronchial hyper-reactivity to histamine 4 days following vaccination with the human respiratory pathogen Haemophilus influenzae was tested in two in vivo and one in vitro models. Conscious vaccinated guinea pigs exposed to aerosolized histamine became asphyxial significantly faster than saline-treated controls. Also the bronchoconstriction in anaesthetized guinea pigs as a result of i.v. histamine was significantly potentiated in the H. influenzae pretreated group. Isoprenaline (30 micrograms/kg) partially inhibited the bronchoconstriction. The difference in histamine sensitivity between the two groups however remained. Protection against bronchoconstriction by atropine on the other hand was significantly enhanced in the vaccinated animals. This suggests a hyper-reactivity of the parasympathetic, cholinergic pathways as a result of H. influenzae vaccination.

ABSTRACT: The B. pertussis model of atopy as proposed by Szentivanyi in 1968 has been a starting point for much research involving the pathogenesis of COLD. Moreover, it supplied more insight into the pharmaco-therapeutic approach toward this group of diseases. In this review, it is shown that products of bacteria considered to be a constituent of the normal flora of the human upper respiratory tract, such as H. influenzae, elicit changes in adrenoceptor responsiveness which are compatible with an enhanced tendency toward bronchoconstriction. One of the features of human atopy is enhanced mediator release after appropriate stimuli resulting in bronchoconstriction. This phenomenon can be mimicked in an animal model, the H. influenzae-vaccinated rat or guinea pig; enhanced histamine synthesis and release are found in vivo as well as in vitro. The effects point in the direction of a beta-adrenergic defect which is not only demonstrable in biochemical but also in physiologically oriented parameters. Pulmonary smooth muscle tissue appears to be less responsive to beta-adrenergic agonists and has an enhanced tendency to contract. The view that these changes are indeed the reflection of changes in adrenoceptor systems has been investigated in guinea pigs and rats. In both species impairment of beta-adrenergic systems together with a reduction in the number of beta 2-adrenoceptors was found after vaccination. Also the involvement of other factors, e.g., catecholamines, has been demonstrated. Comparable changes occur within the pulmonary adrenoceptor populations of COLD patients, suggesting disturbed homeostasis in the autonomic nervous system, possibly leading to bronchoconstriction. The question whether a bacterial factor is important in these changes and might induce, sustain or enhance the effects of other factors or even have a role in the pathogenesis of COLD is discussed in this review.

ABSTRACT: The influence of Haemophilus influenzae on anaphylactic mediator release from ovalbumin-sensitized isolated guinea pig lungs was investigated. Lungs from H. influenzae-vaccinated animals released prostaglandins and thromboxanes following a smaller dose of ovalbumin than was effective in non-vaccinated animals. Histamine release was significantly increased in 4 day-vaccinated animals but not 1 or 10 days after vaccination, while bronchoconstriction was potentiated in 1 and in 4 day-vaccinated animals. This increased histamine release was achieved following 2 micrograms ovalbumin. In contrast, doses of 10 micrograms and 1 mg ovalbumin respectively did not affect and decreased histamine release in the vaccinated group. The inhibition of anaphylactic mediator release by an infusion of 6 x 10(-9) M isoprenaline was significantly attenuated by H. influenzae vaccination. These results indicate an increased sensitivity to antigenic challenge and suggest that the functioning of beta-adrenoceptors was decreased as a result of H. influenzae vaccination.

ABSTRACT: The deeper airways of patients with asthmatic bronchitis are often infected with Haemophilus influenzae. Vaccination of guinea pigs with H. influenzae resulted in a significant impairment of the isoproterenol induced relaxation of isolated tracheal spirals by approximately 50% 4 days following vaccination. In the present study we further investigated the effects of some drugs affecting catecholamine release on the H. influenzae induced functional desensitization of tracheal spirals. Benserazide, an inhibitor of dopa-decarboxylase, completely prevented the reduction in isoproterenol-induced relaxation after H. influenzae vaccination, while no effect on relaxation of tracheal spirals from control animals was detected. On the other hand, inhibiting the re-uptake of catecholamines with desipramine did not influence the relaxation in the H. influenzae vaccinated tracheal spirals. Treatment of control animals with desipramine however resulted in a decreased relaxation of the isolated spirals by 40%. One day following vaccination with H. influenzae the level of norepinephrine in lung tissue was significantly elevated by 71%, and in plasma by 77%, while after 4 days no significant effects were observed. The spontaneous release of norepinephrine, epinephrine and dopamine of tracheal incubates was increased at days 1 and 4 following vaccination. The release of catecholamines from minced lung incubates of H. influenzae pretreated guinea pigs did not differ from that of controls. On the basis of these results it may be suggested that catecholamine metabolism is changed in lungs from H. influenzae vaccinated animals. Catecholamines, accordingly may play a role in the desensitization of beta-adrenoceptors by H. influenzae.

ABSTRACT: Haemophilus influenzae is a bacterium that can be isolated from the deeper airways of asthmatic patients. We investigated the effect of vaccination with H. influenzae on alpha and beta adrenoceptor function in guinea-pig tracheal spirals and lung parenchymal strips. The tracheal spirals from H. influenzae-vaccinated animals showed significantly less relaxation to isoproterenol as compared to controls, independent of whether the trachea was maximally contracted with carbachol or only exhibited an intrinsic tone. Furthermore, an increased contractile response to carbachol was observed in these spirals. To isoproterenol in the presence of a beta-2 adrenergic antagonist (H35/25), or to albutamol alone, the tracheal preparations from H. influenzae-vaccinated animals also showed a decreased relaxation. These results suggest involvement of both beta-1 and beta-2 subtype adrenoceptors. On the other hand, lung parenchymal strips from vaccinated guinea-pigs relaxed significntly more to these drugs. This effect was not influenced by H35/25 but could be inhibited by phenoxybenzamine. Histamine-induced contraction did not differ between the groups. These results indicated that H. influenzae causes a partial blockade of the beta adrenoceptors in tracheal spirals and, therefore, may have important implications in asthmatic bronchitis. In contrast, parenchymal lung strips of the H. influenzae-pretreated group showed an increased relaxation.

ABSTRACT: Infections of the deeper respiratory airways can contribute to the progression of chronic asthmatic bronchitis. In the present report a number of microorganisms affecting the number of beta-adrenoceptors in guinea-pig lung homogenates are described. Haemophilus influenzae, Streptococcus pneumoniae, Bordetella pertussis and Escherichia coli O111B4 induced a significant decrease of the number of beta- adrenoceptors (by approximately 20%). Staphylococcus aureus, influenza A virus and Escherichia coli J5 were not active. These data point to a common factor shared by gram-negative bacilli; i.e. endotoxin. Purified endotoxin of E. coli O111B4 also decreased the number of beta- adrenoceptors, while E. coli J5-LPS did not. This suggests that neutral polysaccharides of bacterial cell walls, especially those in the 'O'- antigenic side chain of gram-negative endotoxins may be responsible for the decrease of beta-adrenoceptor number and therefore contribute to the pathogenesis of chronic asthmatic bronchitis. Intact endotoxin seems to be necessary since neither the isolated lipid nor the polysaccharide part of E. coli O111B4 LPS affected the number of beta- adrenoceptors in the lung.
