Pertussis, also known as whooping cough, is a highly contagious disease, which is most dangerous to infants less than one year old. About half of the babies reported nationally to the Centers for Disease Control and Prevention (CDC) as having the disease are hospitalized. As many as 16/100 babies reported with pertussis get pneumonia, and about 2/100 have convulsions. For those babies reported to have pertussis, about 1/500 has brain problems, some of which can become permanent, and about 1/250 will die because of complications from the disease. Serious illness is less likely in older children and adults. Pertussis vaccine is generally administered in combination with diphtheria and tetanus vaccines, known as DTP vaccine. A primary series of DTP keeps 70-90/100 children from getting pertussis, usually through the elementary school years at least. About half of the children who receive DTP vaccine will not experience any discomfort at all. Some will have minor problems such as soreness, swelling and redness where the shot was given; fever; fussiness; drowsiness; and loss of appetite lasting 1-2 days. Once per 100 to 1000 shots, moderate problems can occur: crying non-stop for 3 hours or more, fever of 105 degrees (F) or higher. For 1 shot in 1750, a child may experience a seizure (convulsions, fits, spasms, twitching, jerking, or staring spells) usually caused by fever, or collapse or fainting (becoming blue, pale, limp, and non-responsive). Very rarely, DTP causes long seizures, decreased consciousness, or coma that usually does not last. Permanent brain damage can very infrequently follow such acute brain problems. There are no tests that can tell in advance if a child will be adversely affected by the DTP vaccine. Definitely the benefits from the DTP vaccine far outweigh the risks for almost all children.

Severe B. pertussis infection in infants is characterized by severe respiratory failure, pulmonary hypertension, leukocytosis, and death. This retrospective case analysis highlights the course and outcome of severe B. pertussis infection treated with extracorporeal membrane oxygenation (ECMO) at a single center. Over the last decade, out of a total caseload of nearly 800 infants and children, 12 infants with severe B. pertussis have been referred for ECMO therapy to our center. All infants with pertussis infection who received ECMO therapy were less than 3 months of age at presentation and unvaccinated. There was a high mortality rate (7 of 12 infants died), which was associated with an elevated neutrophil count at presentation and multiorgan dysfunction characterized by intractable pulmonary hypertension, persistent systemic hypotension, renal insufficiency, and fits. ECMO should be offered to children with pertussis infection and respiratory failure refractory to mechanical ventilation. However, further research is required to determine the optimal management for infants receiving ECMO therapy with this disease.

We present the case of a 6-week-old male infant who had a convulsion due to pertussis pneumonia. He was admitted to our emergency department because of lethargy and hypothermia. He developed a generalized tonic-clonic convulsion, requiring various treatments, including artificial ventilation. A chest CT showed bilateral pneumonia and laboratory data revealed hyponatremia with other features of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Although SIADH has been recognized as a cause of hyponatremia in association with pneumonia, there is little in the literature regarding SIADH caused by pertussis. Hyponatremia caused by SIADH must be considered as a differential diagnosis of seizures in pertussis infection of infants.

The author reviews the use of mixed diphtheria-pertussis-tetanus antigens in the light of the information which has become available in recent years. When diphtheria toxoid and tetanus toxoid, adsorbed or unadsorbed, are added to either plain or adsorbed pertussis vaccine, a satisfactory level of diphtheria antitoxin can be obtained in children over 6 months of age and of tetanus antitoxin in children of any age. As to the duration of immunity, it appears that provided three doses of mixed antigens are given for the primary immunization of children 6 months old a substantial proportion will have effective antitoxin titres three years later, but that with two doses only the antitoxin levels fall more rapidly.Reviewing the evidence, the author considers that mixed antigens will be useful in future immunization campaigns, although he makes it clear that extensive investigations, particularly on the immunizing effect of the pertussis component, must be undertaken before their value can be finally assessed.The reactions to and complications after inoculation with mixed antigens are then discussed, particularly in relation to convulsions, encephalopathy, and poliomyelitis. Finally, the author considers provisional recommendations for the use of mixed antigens, pointing out that the main question in all countries is whether the advantages of giving all three antigens simultaneously to children under 6 month of age, necessary because of the pertussis mortality in the first months of life, outweigh the disadvantages.

We have reviewed evidence of adverse events after exposure to aluminium-containing vaccines against diphtheria, tetanus, and pertussis (DTP), alone or in combination, compared with identical vaccines, either without aluminium or containing aluminium in different concentrations. The study is a systematic review with meta-analysis. We searched the Cochrane Vaccines Field Register, the Cochrane Library, Medline, Embase, Biological Abstracts, Science Citation Index, and the Vaccine Adverse Event Reporting System website for relevant studies. Reference lists of retrieved articles were scanned for further studies. We included randomised and semi-randomised trials and comparative cohort studies if the report gave sufficient information for us to extract aluminium concentration, vaccine composition, and safety outcomes. Two reviewers extracted data in a standard way from all included studies and assessed the methodological quality of the studies. We identified 35 reports of studies and included three randomised trials, four semi-randomised trials, and one cohort study. We did a meta-analysis of data from five studies around two main comparisons (vaccines containing aluminium hydroxide vs no adjuvant in children aged up to 18 months and vaccines containing different types of aluminium vs no adjuvants in children aged 10-16 years). In young children, vaccines with aluminium hydroxide caused significantly more erythema and induration than plain vaccines (odds ratio 1.87 [95% CI 1.57-2.24]) and significantly fewer reactions of all types (0.21 [0.15-0.28]). The frequencies of local reactions of all types, collapse or convulsions, and persistent crying or screaming did not differ between the two cohorts of the trials. In older children, there was no association between exposure to aluminium-containing vaccines and onset of (local) induration, swelling, or a raised temperature, but there was an association with local pain lasting up to 14 days (2.05 [1.25-3.38]). We found no evidence that aluminium salts in vaccines cause any serious or long-lasting adverse events. Despite a lack of good-quality evidence we do not recommend that any further research on this topic is undertaken.

Vaccinations protect to a high degree against infectious diseases, but may cause side effects. In the Netherlands since 1962 the adverse events following immunizations are registered and analysed by the National Institute of Health and Environment (RIVM). Since 1983 a permanent Committee of the Dutch Health Council reviews adverse events reported to the RIVM. With the so-called killed vaccines the side effects are mainly local (redness, swelling, pain) or general (fever, listlessness, irritability, sleep and eating problems). They are seen mainly after DPT-IPV vaccination against diphtheria, pertussis, tetanus and poliomyelitis. Some side effects occur rarely (collapse reactions, discoloured legs, persistent screaming and convulsions) and very rarely serious neurological events are reported. After MMR vaccination against measles, mumps and rubella, cases of arthritis, thrombocytopenia and ataxia are reported sporadically. Usually, they have a spontaneous recovery. During recent years a scala of diseases or symptoms have been associated with vaccination (presumed side effects). Careful and extensive investigations have shown that such hypotheses could not be supported. Examples are allergic diseases as asthma, diabetes mellitus, multiple sclerosis (after hepatitis B vaccination), autism and inflammatory bowel disease (after MMR vaccination) and sudden infant death syndrome. The total number of cases where at least a possible relation between side effects and vaccination is observed--apart from local reactions and moderate general symptoms--is very rare (about 0.25 per 1000 vaccinations) and does not balance the benefits from vaccination. There appears increasing doubt about the use and safety of vaccinations. More research is needed about the motives of people to choose for and against vaccination. The education about vaccination for parents and professionals who are involved with vaccination has to be improved. Internet can play an important role.

In the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), which was conducted from 2003 to 2006, data on acute/infectious and chronic diseases were collected from a population-based sample of 17,641 subjects aged 0 to 17 years. The annual prevalence rates among acute diseases vary widely. Children and adolescents are most frequently affected by acute (infectious) respiratory conditions. 88.5 % of the surveyed children and adolescents experienced at least one episode of common cold within the last 12 months. Among the other acute respiratory infections, bronchitis and tonsillitis were the most frequently encountered conditions with 19.9 % and 18.5 %, respectively. The 12-month prevalence of otitis media and pseudocroup was 11 % and 6.6 %, respectively. 1.5 % of the children and adolescents experienced an episode of pneumonia. Apart from respiratory infections, gastrointestinal infections were very frequently stated as reasons for acute illness. Furthermore, 12.8 % of the children and adolescents experienced a herpetic infection, 7.8 % a conjunctivitis and 4.8 % a urinary tract infection. Lifetime prevalence rates of infectious diseases were as follows: pertussis 8.7 %, measles 7.4 %, mumps 4.0 %, rubella 8.5 %, varicella 70.6 %, scarlet fever 23.5 %. The various chronic somatic diseases in children and adolescents had different lifetime prevalence rates. Most frequently, children and adolescents were affected by obstructive bronchitis (13.3 %), neurodermatitis/atopic eczema (13.2 %) and hay fever (10.7 %). Scoliosis and asthma had been diagnosed by a doctor in 5.2 % and 4.7 % of subjects aged 0-17 years, respectively. The lifetime prevalence rates of the remaining diseases varied between 0.14 % for diabetes mellitus and 3.6 % for convulsions/epileptic fits. For the first time ever, these survey results provide nationwide representative information on the prevalence rates of acute/infectious and chronic diseases in children and adolescents which is based on a population-representative sample.

Whooping cough (pertussis) is a contagious disease caused by Bordetella pertussis that can be prevented by vaccination. The disease is particularly severe in infants who are less than 3 months old, who are not protected against the disease and are often contaminated by their parents. Atypical presentations are frequent and neonatal pertussis is rare. We report a case of malignant whooping cough in a newborn infant probably contaminated by her mother. Diagnosis was suspected clinically because of persistent coughing fits and was confirmed by serology. Treatment was successful. We discuss the diagnostic, therapeutic, and preventive issues of whooping cough in developing countries. In Africa, where complementary investigations such as PCR are seldom accessible, a careful clinical study and the analysis of the absolute rate of lymphocytes could be an alternative for the diagnosis of whooping cough. Vaccination of teenagers and adults is also problematic in poor countries. High-performance new vaccine candidates may contribute to a better control of whooping cough.

We estimated the sensitivity, i.e., the proportion of all cases of adverse events following immunization (AEFIs) reported to the Brazilian passive surveillance for adverse events following immunization (PSAEFI) with the diphtheria-tetanus-whole-cell pertussis-Haemophilus influenzae type b (DTwP/Hib) vaccine, as well as investigating factors associated with AEFIs reporting. During 2003-2004, 8303 AEFIs associated with DTwP-Hib were reported; hypotonic-hyporesponsive episodes (HHEs), fever and convulsions being the most common. Cure without sequel was achieved in 98.4% of the cases. The mean sensitivity of the PSAEFI was 22.3% and 31.6%, respectively, for HHE and convulsions, varying widely among states. Reporting rates correlated positively with the Human Development Index and coverage of adequate prenatal care, correlating negatively with infant mortality rates. Quality of life indicators and the degree of organization of health services are associated with greater PSAEFI sensitivity. In addition to consistently describing the principal AEFIs, PSAEFI showed the DTwP/Hib vaccine to be safe and allayed public fears related to its use.
