An earlier report on the Nigerian expanded programme on immunization (EPI), covering 1974-1988, failed to demonstrate a clear-cut impact of the programme. This report attempts to determine the effectiveness of EPI in Borno State, Nigeria. We analysed trends in routine notifications for diphtheria, pertussis, tetanus, tuberculosis, measles, and pneumonia, from 1985 to 1991; data on poliomyelitis were excluded because of poor documentation, while we included data on pneumonia for comparison. We also performed a before (1983-1987) after (1988-1991) comparison in terms of the intensifications of EPI by age-specific strata amongst paediatric hospitalization for all EPI diseases at the University of Maiduguri Teaching Hospital, the sole referral hospital for childhood infectious diseases. Our results show an apparent reduction in morbidity from diphtheria, pertussis, tetanus, measles and pneumonia, and this was particularly prominent following intense vaccinations between 1988 and 1991. The reduction in these EPI diseases and pneumonia occurred despite the prevailing adverse socioeconomic conditions, and the absence of a specific control strategy for pneumonia in Nigeria. On the other hand, in spite of national BCG coverage of about 90% there has been a recent (1989-1991) increase in the registered cases of tuberculosis in infants and older children in Borno State. There is a need to intensify other intervention measures alongside EPI activities.

We studied clinical effects of meropenem (MEPM, SM-7338), a newly developed parenteral carbapenem beta-lactam drug, and following results were obtained. The patients were administered with 16-20 mg/kg of MEPM every 8 hours using 1 hour drip infusion. 1. Clinical effects of MEPM were studied in 10 children with various infectious diseases: 1 with acute bronchitis, and 2 each with acute tonsillitis, acute bronchopneumonia, acute pneumonia, acute urinary infection, and 1 with pertussis pneumonia. The case of pertussis pneumonia later developed bronchiolitis obliterans, hence a steroid and gamma-globulin were used. This case was excluded from the clinical evaluation. The efficacy rate was 100% (9/9), and the bacteriological eradication rate was 100% (6/6). 2. No side effects were noted. Clinical laboratory test values were investigated in 10 patients. There was a case of abnormal laboratory test findings with mild elevations of liver functions such as GOT, GPT, and gamma-GTP. These abnormalities disappeared in 1 week after the end of therapy.

Development of the Japanese acellular pertussis vaccines (APVs) of the 1980s involved six procedural or conceptual features that were discontinuous with the then-accepted views of how pertussis vaccines should be made and tested. These discontinuities were: modification of the standard intracerebral mouse test for protective potency; use of culture supernates, rather than cells, of Bordetella pertussis as the feedstock for antigen purification; use of haemagglutination as a measure of protective antigen(s); identification of pertussis toxin (PT) as the main protective antigen; complete inactivation of the biological activities of PT by formalin; and the use of a single strain of B. pertussis. Several of these discontinuities had long precedence in the pertussis literature, but the original observations had not been incorporated into the mainstream of pertussis vaccinology and were therefore 'premature'. The APVs, purified from culture-supernates, emerged after a long period of unsuccessful research on the split-cell pertussis vaccines, i.e. those derived from the bacterial cells themselves. There is a brief discussion of why APVs have taken so long to obtain acceptance outside Japan, and of how the listed discontinuities may be explicable in terms of antigen processing by the immune system. General lessions, applicable to vaccines for other infectious diseases, may be learned from this account of how APVs have evolved from whole-cell pertussis vaccines.

University students with persistent cough of greater than or equal to 6 days' duration were evaluated for evidence of infection with Bordetella pertussis. Of 130 students studied during a 30-month period, 34 (26%) were found to have evidence of recent infections with B. pertussis. Infection was identified by direct fluorescent antibody assay of a nasopharyngeal specimen in one student and serologically in 33 additional subjects. B. pertussis was not recovered on culture of nasopharyngeal specimens from any subjects. Students with B. pertussis infection were identified in seven of the eight 3-month periods in which students were enrolled during the 30-month investigation, suggesting an endemic rather than epidemic pattern of infection in this university population. Illnesses of students with pertussis were similar to the illnesses of students without pertussis. The findings in this study suggest that adult populations in which endemic illness occurs at a relatively constant rate may be the reservoirs for pertussis outbreaks in susceptible children. Immunization programs in the future will need to employ booster doses for adults if complete control of B. pertussis infection is our goal.

Low immunization rates among US preschool children suggest a need for improved immunization practices. Immunization and encounter records were reviewed to ascertain immunization rates and missed opportunities for vaccine administration among 515 preschool children who were active patients at a hospital-based primary care center serving lower socioeconomic status families in Rochester, NY. The point prevalence at a mean age of 4.4 years for lack of one or more recommended immunizations was 27%; 7% were missing measles-mumps-rubella, 18% were missing Haemophilus influenzae type b, 8% were missing two or more diphtheria-tetanus-pertussis, and 4% were missing two or more oral poliovirus immunizations. A visit was counted as a missed opportunity if an immunization was due but not given. Over the period from birth through age 36 months, 422 (82%) of children missed at least one immunization opportunity. For these 422 children, there was a mean of 7.2 missed opportunities per child. Although 64% of missed opportunities occurred at an acute illness visit, 36% occurred at well-child, administrative, follow-up, or chronic illness visits. Review of 200 medical records randomly selected from all opportunities at acute illness visits found no contraindication in 63% (50% nonfebrile infectious disease, 13% minor noninfectious problems). Findings for random samples of 100 missed diphtheria-tetanus-pertussis opportunities for children aged 2 to 6 months and 100 missed measles-mumps-rubella opportunities for children 15 to 24 months were similar to findings for the sample of all acute illness visits. Emergency department visits, where immunization records were not readily available, accounted for 18% of missed opportunities.(ABSTRACT TRUNCATED AT 250 WORDS)

The therapeutic perspectives of flomoxef, SCE 2787, cefpirome, cefepime, latamoxef, cefotaxime and of piperacillin plus tazobactam were comparatively evaluated by their in vitro activity against 1119 clinical isolates of 83 bacterial species. Escherichia coli, Klebsiella spp. Enterobacter sakazakii, Proteus spp. and Shigella spp. were about equally susceptible to the cephalosporins (MIC90: 0.06 to 0.5 mg/l), while the MIC90 for piperacillin plus tazobactam was between 2 and 16 mg/l. Enterobacter cloacae, Enterobacter aerogenes and Serratia spp. were most susceptible to SCE 2787, cefpirome and cefepime (MIC90: 0.06 to 2 mg/l) followed by latamoxef, cefotaxime, flomoxef and piperacillin plus tazobactam. For Citrobacter spp., Providencia spp. and Yersinia enterocolitica MIC90 were between 0.06 and 0.5 mg/l. Flomoxef was between 2 to 4 log2 less active against these species but more active than piperacillin plus tazobactam (MIC90: 2 and 8 mg/l). Morganella morganii and Hafnia alvei were most susceptible to cefepime, cefpirome and latamoxef (MIC90: 0.13 to 0.5 mg/l) while cefotaxime (MIC90: 8 mg/l) and piperacillin plus tazobactam (MIC90: 8 and greater than 64 mg/l) were the least active compounds. SCE 2787, cefepime and cefpirome were the most potent beta-lactams against the majority of the 13 species of non-fermentative bacilli (NFB) investigated (MIC90: 0.5 to 16 mg/l). The oxacephems were the least active compounds against NFB. Cefepime was the most active of the compounds included against Pseudomonas aeruginosa (MIC90: 16 mg/l). Haemophilus spp., Neisseria gonorrhoeae and Bordetella pertussis were most susceptible to cefotaxime (MIC90: 0.03 to 0.06 mg/l). Latamoxef had the lowest activity of all compounds against gram-positive cocci. Flomoxef was the most active compound against penicillinase producing Staphylococcus aureus and about equally active as the other betalactams against methicillin susceptible staphylococci of other staphylococcal species.(ABSTRACT TRUNCATED AT 250 WORDS)

Researchers analyzed data from the National Child Development Study--a cohort of every child born in England, Scotland, and Wales during the 1st week of March 1953 with follow up studies in 1965, 1969, 1973, and 1980-1981 to examine the relationship between health status and birth order and whether children with low birth orders were less likely to experience illness than those with older siblings. 1st born children tended to have received the needed number of immunizations, but children of higher birth order did not tend to have received them. Further they were more likely to have attended infant welfare and toddler clinics for health care than children of higher birth order. The only childhood contagious disease which demonstrated a social class effect was pertussis. It tended to afflict children from nonmanual homes regardless of birth order. Absences from school lasting between 1 week-1 month of 1st born children were less frequent than for other children. The leading reasons for 1st, 3rd, and later born 11 year old children who experienced such long absences included infectious diseases; bronchitis; ear, nose, and throat complaints; pneumonia; tonsillitis, or viral influenza. After age 15, 1st and 2nd born children were less likely to be absent and, if absent, they tended to only miss 1 week of school. Significantly more 3rd and 4th born children were absent from school for 1 week-3 months. 1st and 2nd born children from more affluent families tended to have early childhood asthma. In conclusion, the health experiences of the later birth orders were different than those of the 1st born. This did not mean, however, that later birth order children were in poorer health than 1st born children.

Bordetella pertussis and the disease whooping cough have mysterious unique features among bacterial infectious diseases. Numerous studies gradually provided information that permitted the development of a pertussis vaccine and the assessment of its potency relative to human efficacy. The advances in the understanding of B. pertussis, its pathogenicity and immunity that led to the development of a pertussis vaccine are presented.

We studied case reports of bacterial meningitis and estimated its incidence per 100,000 in three areas of Osaka Prefecture which differed in population and vaccination schedule for the years of 1987 and 1988. To estimate incidence, we used a simple mathematical method derived from surveillance data for a reported number of exanthem subitum to obtain a coverage constant. With this coverage constant, we estimated the incidence of bacterial meningitis per 100,000 population for each area. In the Toyono area, with a population of about one million, the acellular pertussis vaccine series is started in children of three to six months of age and the incidence of bacterial meningitis per 100,000 was 1.95 in 1987 and 5.35 in 1988. Conversely, in Osaka City and Sakai City, with populations of about 2.6 and 0.8 million, respectively, the vaccine is given to children over two years of age and the incidence of bacterial meningitis per 100,000 was estimated to be 6.25 and 3.23 in 1987 and 14.62 and 1.07 in 1988, respectively. Thirteen cases of bacterial meningitis had been reported by Minoh City Hospital, in the Toyono area, and the Osaka City Infectious Disease Center in 1987 and 1988. Patients were seven males and six females and aged from less than a month to four years old. In six, the causal agent was Haemophilus influenzae type B, in three, Group B streptococcus, in two, Neisseria meningitidis and in one, Listeria monocytogenes. Only one of the thirteen patients had received an acellular pertussis vaccine.(ABSTRACT TRUNCATED AT 250 WORDS)

In October 1984 in Sweden, a phase II trial of Biken acellular Pertussis vaccine was started and in 1986, a phase III trial of the same vaccine was begun. During the phase III trial, there were three cases of deaths out of 1,385 of study children at two, four and ten weeks after the second dose of the vaccine, due to severe invasive bacterial infections such as H. influenzae, Pneumococcus, or Meningococcus infection. A number of arguments arose about the results of the Phase III trial. No one can either prove or disprove the association between invasive bacterial infection and administration of acellular pertussis vaccine. The purpose of this paper is to discuss the side effects of Biken acellular DPT vaccine. The pediatricians inquired about the physical status of the children who received Biken acellular DPT vaccine. During the observation period, three out of 940 infants suffered from infectious diseases. One suffered from measles, the other from varicella and the last from mumps. Our retrospective study did not reveal any severe invasive bacterial infection cases cases such as the ones experienced in Sweden.
