Two studies were undertaken to investigate the concomitant administration of combined hepatitis A/B vaccine with a diphtheria-tetanus-acellular pertussis-inactivated poliomyelitis vaccine mixed with Haemophilus influenzae vaccine (DTPa-IPV/Hib), or with a measles-mumps-rubella vaccine (MMR), during the second year of life. On completion of the vaccination course, all subjects were seropositive or seroprotected against all antigens except for one subject who was seronegative for anti-PT. Seropositivity and seroprotection rates for all other antibodies were comparable to reference values for each vaccine component, indicating that the immunogenicity of MMR, DTPa-IPV/Hib and combined hepatitis A/B vaccines is not impaired by co-administration. All vaccines were well tolerated.

Hematopoietic stem cell transplant recipients lose immune memory of exposure to infectious agents and vaccines accumulated through a lifetime, and therefore need to be revaccinated. Reimmunization protocols vary greatly among hematopoietic stem cell transplant centers. Diphtheria and tetanus toxoids, pertussis vaccine, Haemophilus influenza type B conjugate, 23-valent pneumococcal polysaccharide, inactivated influenza and polio vaccine and live attenuated measles-mumps-rubella vaccine are the currently recommended vaccines to be included in a vaccination program after hematopoietic stem cell transplant. Other variables, such as stem cell source, new adjuvants, T-cell depleted transplants, nonmyeloablative conditioning and donor immunization have recently been introduced and a constant update of current recommendations are needed. Studies recently published, the use of other vaccines and the perspectives for different vaccination protocols are discussed in this review.

Arthritis caused by infectious agents can be secondary to direct invasion of the joint space or to immune mechanisms (subsequent to or concomitant to an infection). Septic arthritis refers to a situation when bacteria can be cultured in synovial fluid. Arthritis can complicate for example meningococcemia or infection by Neisseria gonorrhoeae or Haemophilus influenzae. Reactive (postinfectious) arthritides are an important diagnostic category within a pediatric rheumatology practice. Yersinia and, less frequently, Salmonella, play an important role in postdiarrheal disorders. The arthritis that can ensue is usually oligoarticular and occurs 1-2 weeks after the enteric infection. Reiter's syndrome, rare in the pediatric age, is characterized by the triad urethritis-conjunctivitis-arthritis. Postviral arthritides can occur after a variety of viral infections, including Parvovirus B19, rubella, and others (e.g. hepatitis B, Epstein-Barr virus, chickenpox, mumps). Especially in patients with acute arthritis, the presence of preceding infections should always be investigated. Although the majority of postinfectious arthritides are self-limiting in nature and do not require specific treatment, conditions such as Lyme borreliosis and rheumatic fever can be associated with significant morbidity, and sometimes can be even lethal.

The objective of this study was to evaluate humoral immunity of allergic respiratory children with chronic/recurrent sinusitis. Twenty-seven allergic respiratory (persistent mild/moderate asthma and persistent allergic rhinitis) children (7-15-year old) with chronic or recurrent sinusitis were evaluated. Patients had symptoms and abnormal computer tomography scan even after two adequate treatments (long-lasting antibiotics, decongestants, and short-term oral corticosteroids). clinical examination, sweat test, total blood cell count, measurement of serum levels of: total and specific IgE, immunoglobulins (G, M, A), IgG subclasses, antibodies to Haemophilus influenza type b (IgG anti-Ps Hib) and pneumococcal serotypes (IgG anti-Ps 1, 3, 5, 6B, 9V, and 14) before and after active immunization (Act-Hib and Pneumo23, Aventis Pasteur SA, Lyon, France), Rubella neutralizing antibody titers and human immunodeficiency virus antibodies. Specific IgE to inhalant allergens higher than class III were observed in 24/27 patients. One patient had IgA plus IgG2 deficiency and other an IgG3 deficiency. Eight and 12 of 27 patients had IgG2 and IgG3 serum levels below 2.5th percentile, respectively. Immunological responses to protein and polysaccharide antigens were normal in all patients. Although our patients have been appropriately treated of their allergic diseases, they persisted with chronic/recurrent sinusitis and 60% of them had a documented osteomeatal complex blockade. In spite of the diagnosis of IgA plus IgG2 deficiency and an isolated IgG3 deficiency, in all patients an adequate response to Ps antigens was observed. Primary and/or secondary humoral immunodeficiency seems not to be the main cause of chronic/recurrent sinusitis in patients with respiratory allergic disease.

Vaccines are responsible for the control of many infectious diseases that were once common in the United States, including polio, measles, diphtheria, pertussis (whooping cough), rubella (German measles), mumps, tetanus, and Haemophilus influenzae type b. National efforts to generate collaboration between federal, state, and local governments and public and private health care providers have resulted in record high levels of vaccination coverage in the United States. The high rate of US vaccinations is paralleled by growing concerns about the safety of their delivery. The variety of substances used in vaccines sometimes causes the development of cutaneous reactions in susceptible adults and children. This article will review adverse cutaneous events consistent with hypersensitivity reactions to the following ingredients in vaccines: aluminum, thimerosal, 2-phenoxyethanol, formaldehyde, and neomycin.

Not many inventions in medical history have influenced our society as much as vaccination. The concept is old and simple. When Edward Jenner published his work on cowpox, "variolation" was quite common. In this procedure, pus of patients with mild smallpox was transferred to healthy individuals. Meanwhile smallpox has been eradicated worldwide. Diseases such as poliomyelitis, diphtheria or tetanus almost disappeared in industrialized countries. The same happened with epiglottitis and meningitis due to Haemophilus influenzae type b (Hib) after vaccination against Hib was introduced in Switzerland in 1990. This success was possible because of routine vaccination. Immunization is a save procedure and adverse events are much lower than complications in the natural course of the prevented diseases. However vaccinations were accused to cause diseases themselves such as asthma, multiple sclerosis, diabetes mellitus, chronic arthritis or autism. Hitherto no large cohort study or case-control-study was able to proof responsibility of vaccines in any of these diseases. Public media are eager to publish early data from surveillance reports or case reports which are descriptive and never a principle of cause and effect. In large controlled trials there was no proof that vaccination causes asthma, hepatitis-B-vaccination causes multiple sclerosis or macrophagic myofasciitis, Hib-vaccination causes diabetes mellitus, rubella-vaccination causes chronic arthritis, measles-mumps-rubella-vaccination causes gait disturbance or thiomersal causes autism. These results are rarely published in newspapers or television. Thus, many caring parents are left with negative ideas about immunization. Looking for the best for their children they withhold vaccination and give way to resurgence of preventable diseases in our communities. This must be prevented. There is more evidence than expected that vaccination is safe and this can and must be told to parents.

Childhood vaccines have had an enormously beneficial impact on human health. Large-scale vaccination programs have controlled diseases associated with high morbidity and mortality such as poliomyelitis, smallpox, diphtheria, tetanus, yellow fever, pertussis, Haemophilus influenzae, Streptococcus pneumoniae, measles, mumps, and rubella. Human papillomavirus (HPV) is a significant source of morbidity and mortality throughout the world. In the United States, HPV is the most common sexually transmitted infection (STI), and sexually active adolescents are at particularly high risk for HPV acquisition. Genetic and epidemiologic studies have clearly demonstrated that HPV infection is a necessary cause of both cervical cancer and genital warts. More than 99% of cervical cancers contain at least one high-risk HPV type, and approximately 70% contain HPV types 16 or 18. Moreover, low-risk HPV types 6 or 11 are responsible for approximately 90% of genital warts and almost all cases of recurrent respiratory papillomatosis. Thus, a vaccine that could prevent HPV acquisition would have the potential to significantly reduce the incidence of both childhood and adult diseases.

A personal view of the evolution of the New Zealand immunisation schedule (from the perspective of someone who has been involved in the decision-making process since 1980) is presented in this article. The rationale behind changes to vaccination strategies to control pertussis, hepatitis B, polio, measles, mumps and rubella, and Haemophilus influenzae type b are presented. Finally brief comment is made on the National Immunisation Register and the likely vaccines to be introduced into the schedule in the foreseeable future.

Intensified chemotherapy regimens resulting in improved survival of children with acute lymphocytic leukemia (ALL) lead to concerns about therapy-induced immune damage reflected by the loss of protection of previous immunizations and the efficacy of (re-)vaccination. The severity of secondary immunodeficiency, however, is not clear and knowledge is based on a limited number of studies. We performed a systematic review on literature concerning vaccination data of children with ALL published since 1980. Eight studies fulfilled the inclusion criteria. Regarding antibody titers after treatment, the number of children who had preserved the defined protection level for antibodies differed widely, ranging from 17 to 98% for diphtheria, 27 to 82% for Bordetella pertussis, 20 to 98% for tetanus, 62 to 100% for poliomyelitis, 35 to 100% for Haemophilus influenzae type B (HiB), 29 to 92% for mumps, 29 to 60% for measles and 72 to 92% for rubella. Most patients however responded to revaccination, demonstrating immunological recovery. Although the designs and results of the included studies varied widely, it can be concluded that cytostatic therapy for ALL in children results in a temporarily reduction of specific antibody levels. Memory is preserved but revaccination may be warranted. This is the first systematic review and the best possible current approximation of chemotherapy-induced immune damage in children after ALL treatment.

The National Immunization Survey (NIS) provides vaccination coverage estimates among children aged 19-35 months for each of the 50 states and selected urban areas. Findings from the 2005 NIS include nationwide increases in coverage with >/=3 and >/=4 doses of pneumococcal conjugate vaccine (PCV) and continued high levels of coverage for the other recommended vaccines and vaccine series. In addition, no racial/ethnic disparities in coverage estimates were observed in the 4:3:1:3:3:1 vaccine series, the recommended series for children aged 19-35 months that includes DTP/DT/DTaP; poliovirus vaccine; measles, mumps, and rubella vaccine (MMR); Haemophilus influenzae type b vaccine; hepatitis B vaccine; and varicella vaccine. An important accomplishment indicated by the 2005 NIS data is the achievement of <50% coverage for the full series of PCV (>/=4 doses) and <80% coverage for >/=3 doses within 5 years after being added to the U.S.-recommended childhood immunization schedule in 2000. This occurred despite shortages of this vaccine during 2001-2004, which might have affected accessibility to PCV.
