A high proportion of Cree and other North American Indian children have a chronic cough and many have bronchial wall thickening on radiographs, reminiscent of white children with asthma, mild cystic fibrosis, or immune deficiency. When compared to postmortem studies, radiographs underestimate the degree of bronchial wall thickening present. As compared to white children, Indian children in the first two years of life are more susceptible to recurrent bronchitis and pneumonia, are much more likely to develop pneumonia with rubeola and pertussis, and are more likely to develop chronic lung disease after adenovirus infections. Staphylococcal complications with pneumatocele formation are more common. A greater number acquire pneumonia while in hospital with other medical or surgical problems. Indian children with pneumonia recover more slowly, and some continue to deteriorate even after admission to hospital.

Ninety-seven preterm infants were immunized with diphtheria-tetanus-pertussis (DTP) prior to discharge from hospital. The mean gestational age at birth was 28.1 weeks (range 24-34) and the mean age at immunization was 80.6 days (range 44-257). Nineteen (20%) infants developed apnoea or bradycardia within 24 h of immunization. The infants who developed apnoea and/or bradycardia had a younger gestational age at birth than those who did not (P = 0.03), were artificially ventilated for longer (P = 0.01) and were more likely to have a diagnosis of chronic lung disease (P = 0.006). In the majority of infants these events were not clinically significant. Two infants who developed concurrent upper respiratory tract infections required additional oxygen and one of them was treated with oral theophylline. In general, it is safe practice to immunize preterm infants with DTP unless otherwise contraindicated. However, it is recommended that cardiorespiratory function is monitored after immunization in very preterm infants who had prolonged ventilatory support and/or chronic lung disease.

Immune hypersensitivity to house dust mite antigen (HDM) is a frequent cause of respiratory allergy. The objective of this study was to determine whether exposure to NO2, a common indoor air pollutant, modulates immune responses to HDM and influences immune-mediated lung disease. Brown Norway rats were immunized ip with 100 micrograms semipurified antigen and Bordetella pertussis adjuvant and challenged 2 weeks later with an intratracheal injection of 50 micrograms of a crude antigen preparation. Exposure to 5 ppm NO2 for 3 hr after both immunization and challenge procedures resulted in significantly higher levels of antigen-specific serum IgE, local IgA, IgG, and IgE antibody than air controls, and increased numbers of inflammatory cells in the lungs. Lymphocyte responsiveness to antigen in the spleen and MLN was also significantly higher in NO2-exposed animals. These data show that exposure to a common air pollutant can upregulate specific immune responses and subsequent immune-mediated pulmonary inflammation.

House dust mite (HDM) antigen is one of the most common allergens associated with extrinsic asthma. In a model of allergic lung disease, Brown Norway (BN) rats sensitized to HDM with alum and Bordetella pertussis adjuvants produce high levels of IgE antibody and experience bronchoconstriction, increased airway hyperresponsiveness (AHR) to acetylcholine (ACh), and pulmonary inflammation after antigen challenge. The purpose of this study was to determine whether these asthmatic symptoms could be transferred from sensitized animals to naive recipients via humoral or cellular factors. Syngeneic recipient rats were injected (intraperitoneally with 4 x 10(7) cells (precultured overnight with either HDM or bovine serum albumin [BSA]) from lymph nodes of sensitized or control rats, respectively. Other groups received a tail-vein injection of serum from either HDM-sensitized or control rats. Antigen challenge in rats injected with sensitized cells caused increases in pulmonary inflammation and in AHR, but no changes in immediate bronchoconstriction as compared with control recipients. Antigen challenge in serum recipients resulted in immediate bronchoconstriction but had no effect on AHR or on pulmonary inflammation. These data show that immune-mediated lung inflammation and AHR are promoted by antigen-specific lymphocytes, whereas immediate allergic responses are caused by serum factors.

The main goal of the study was to check the hypothesis that pertussis infection may cause a lung function deterioration in children. Cross sectional study was carried out in 1997 among 992 schoolchildren attending the fourth form of elementary schools in Krakow. In the course of the study the epidemiologic interviews on respiratory health of children and spirometric testing were performed. Spirometric indices (FVC, FEV1 and FEF25-75%) were inversely correlated with allergic diseases, wheezing symptoms and tobacco smoking of mother in pregnancy, however, the effect of the latter variable was of border significance. Socio-economic status of the family and number of infections in lower respiratory tract in children reported over the last year were not related to the lung function level. Children who reported pertussis infection in the past showed significantly lower values of FEV1 and FEF25-75%. The results obtained suggest that pertussis infection may have a detrimental effect on the lung function of preadolescent children. Since these children may be more susceptible to environmental hazards and development of obstructive lung disease, therefore, it is justified to postulate a monitoring of lung function in children after pertussis infection throughout a longer period to detect early lung obstruction and setting up proper prophylactic measures.

Congenital and neonatal viral infections usually display their acute manifestations in highly recognisable ways, for example, congenital rubella, cytomegalovirus (CMV), varicella, human immunodeficiency (HIV) and herpes simplex virus (HSV) infection. By contrast, congenital hepatitis B virus (HBV) infection may go undetected for years. Some of these are preventable, but what is not immediately apparent is that the long-term consequences are being prevented as well. The long-term consequences of congenital and neonatal infections include endocrine, immunological and cardiovascular disease, deafness, visual problems, intellectual handicap and cerebral palsy. With the survival of HIV-infected infants into adulthood the long-term consequences will soon be described. Maternally and neonatally transmitted HBV infection predisposes to carriage, liver cirrhosis and hepatocellular carcinoma in young adults. Neonatal HBV vaccination prevents adult cancer. Acquired viral infections may predispose to subsequent lung disease, malabsorption, fertility problems or neurological disability. In the prevention of acquired rubella, varicella, HBV, influenza, poliovirus, measles and hepatitis A, one should mention the added bonus of preventing secondary cases by preventing transmission from infants and children to other children and adults. Preventing paediatric HSV, HBV and HIV infection in females may even be preventing subsequent transmission to future generations. Turning to paediatric bacterial infections, vaccinating infants and young children against pertussis could not only prevent transmission to older children and adults but also break the cycle, which then transmits from adults back to infants and young children. There is evidence that disease in older age groups, including adults, has been prevented by virtue of herd immunity from paediatric vaccination, e.g. Neisseria meningitidis Group C and Streptococcus pneumoniae. The add-on benefits for other generations, including for adults, arising from the prevention of paediatric infections are considerable.

Morbidity and mortality due to vaccine-preventable diseases are high among persons with underlying medical conditions. Thus, inactivated influenza and pneumococcal polysaccharide vaccines are recommended for individuals with cardiac disease, diabetes mellitus, chronic obstructive pulmonary disease, immunosuppression, and other chronic illnesses. Inactivated influenza vaccine is recommended for pregnant women and for persons with asthma and neuromuscular disease. Palivizumab, a respiratory syncytial virus immunoglobulin preparation, is recommended for certain infants with prematurity and chronic lung disease. Health care workers are at high risk for acquiring and transmitting hepatitis B, pertussis, measles, varicella, and influenza; hence, vaccination against these diseases is recommended. A signed declination is recommended for health care workers who refuse influenza vaccination.

Premature infants have an increased risk of experiencing infectious diseases, some of which are vaccine preventable diseases. Maturation of immune responses begins with exposition to environmental antigens and in premature infants as fast as in term-infants. Premature infants must be vaccinated at 2 months of age, whatever the gestational age. Acellular Pertussis vaccine and pneumococcal conjugate vaccine must be given as early as possible, at two months of age. Immunization schedule in premature infants is the same as in full-term infants : three injections one month apart with a pentavalent vaccine : Diphteria, Tetanus, Poliomyelitis, Pertussis and Haemophilus type b. First injection of hepatitis B vaccine must not be taken in account when this vaccine is given at birth to infants under 2 kg birth weight. Premature infants 6 months of age or older and experiencing chronic lung disease have to be vaccinated against influenza. In all cases, surroundings have to be vaccinated. Apnea and/or bradycardia have been reported within the 48 hours following vaccination in premature infants before 32 weeks of gestational age and justify giving their first injection of vaccine under cardiorespiratory monitoring. These injections will be given before discharge as often as possible.

Mycobacterium bovis Bacillus Calmette-Guerin (BCG) has been shown to down-regulate experimental allergic asthma, a finding that reinforced the hygiene hypothesis. We have previously found that recombinant BCG (rBCG) strain that express the genetically detoxified S1 subunit of pertussis toxin (rBCG-S1PT) exerts an adjuvant effect that enhances Th1 responses against BCG proteins. Here we investigated the effect of this rBCG-S1PT on the classical ovalbumin-induced mouse model of allergic lung disease. We found that rBCG-S1PT was more effective than wild-type BCG in preventing Th2-mediated allergic immune responses. The inhibition of allergic lung disease was not associated with increased concentration of suppressive cytokines or with an increased number of pulmonary regulatory T cells but was positively correlated with the increase in IFN-gamma-producing T cells and T-bet expression in the lung. In addition, an IL-12-dependent mechanism appeared to be important to the inhibition of lung allergic disease. The inhibition of allergic inflammation was found to be restricted to the lung because when allergen challenge was given by the intraperitoneal route, rBCG-S1PT administration failed to inhibit peritoneal allergic inflammation and type 2 cytokine production. Our work offers a nonclassical interpretation for the hygiene hypothesis indicating that attenuation of lung allergy by rBCG could be due to the enhancement of local lung Th1 immunity induced by rBCG-S1PT. Moreover, it highlights the possible use of rBCG strains as multipurpose immunomodulators by inducing specific immunity against microbial products while protecting against allergic asthma.
