Basic and clinical studies of latamoxef (LMOX) were carried out in neonates. In basic study, these neonates consisted of 16 mature babies and 12 premature babies. LMOX was administered at dose of 10 and 20 mg/kg, either as a single intravenous injection or as a 60 minutes intravenous drip infusion. Both the mature babies and the premature babies were divided into 3 subgroups as a function of the number of days after birth (0--3, 4--7 and 8--25 days). A clinical study of LMOX was performed in 12 neonates aged between 0--35 days, consisting 6 males and 6 females. (Purulent meningitis 4 cases, septicemia 1 case, bronchopneumonia 5 cases, pertussis pneumonia 1 case, urinary tract infection 1 case). Serum concentration and urinary excretion 10 mg/kg, one shot intravenous injection In the 3 subgroups of neonates the peak serum concentrations of LMOX were found to range from 14.6 to 28.9 micrograms/ml. Although there was no significant difference, the half-life of the drug became shorter as the age of the neonates increased, these values were 4.46, 3.85 and 3.30 hours, respectively. 10 mg/kg, 60 minutes intravenous drip infusion. As above, the peak LMOX serum concentrations were found to range from 23.7 to 38.9 micrograms/ml, the half-lives of the 3 subgroups were 4.83, 2.48 and 3.01 hours, respectively. And urinary excretions were ranged from 46.0 to 56.5% for 6 hours. 20 mg/kg, one shot intravenous injection The peak serum concentrations were found to range from 31.0--82.5 micrograms/ml, and it was found out 3.29--15.9 micrograms/ml at 8 hours after the injection. There was a tendency for the half-life to be shorter in more mature subjects in 3 subgroups. 20 mg/kg, 60 minutes intravenous drip infusion In the 3 subgroups, the peak concentration was the level existing at the end of the intravenous drip infusion, and that showed a range of 41.8--58.6 micrograms/ml. Half-lives were found out the significant difference to their age, these showed 4.08, 2.31 and 2.52 hours. Cerebrospinal fluid concentrations of LMOX Cerebrospinal fluid concentrations of LMOX were studied in 2 cases at the dose about 50 mg/kg. In 1 case, that's meningitis estimated E. coli organism, the cerebrospinal fluid concentrations of LMOX were found to range from 29.0 to 49.9 micrograms/ml in that acute state. In another case from N. meningitidis, that values were found to range 12.1 to 21.3 micrograms/ml. These cerebrospinal levels were superior value at it's penetration ratio.

In the present study, auditory brainstem responses (ABR) were recorded in 60 high-risk neonates in the intensive care unit selected by the following criteria: Birth-weight less than 2000 g, hyperbilirubinemia requiring phototherapy or exchange transfusion, idiopathic respiratory distress syndrome, artificial ventilation, asphyxia, sepsis or meningitis, intracranial haemorrhage, neurological symptoms and potential ototoxic medication (aminoglycoides, furosemide). The infants tested ranged in gestational age from 27-44 weeks. The ABR testing was performed in a sound-proof room using the Madsen (ERA-74) equipment. Four infants did not reveal responses to 70 dB HL ("nonresponders"), and the total of 10 neonates (16.6%) had abnormal ABR-tests, when the physiological changes related to gestational age and conceptional age (gestational age plus the age after birth) were taken into account. The 10 neonates with abnormal tests were reexamined after discharge, and in six there were no improvement of threshold sensitivity. three of the "nonresponders" were retested several times within the two years after birth (one died at age 18 months of pertussis), and none of them revealed ABR at stimulus intensity of 70 dB HL. They all attend an audiological training program started at age of six months as a consequence of the early diagnosis of impaired auditory function. It is our opinion that a routine ABR-evaluation should be performed on high risk neonates (criteria mentioned above) in the newborn intensive care unit. Retesting of infants with abnormal responses within three months, and several times within the next two years if abnormal responses persist, is important. Transient impairment of auditory functions is not uncommon in these infants. However, the children with persisting hearing impairment should be discovered early to attend an early audiological training program.

An estimated 8 million infants and 2 million children and adults may die from tetanus during the 1990s despite efforts by the World Health Organization (WHO) to eliminate it by 1995. Vaccination to prevent postabortal and maternal tetanus has been neglected. The immunization of preschool children and of pregnant women has omitted adolescent girls, who are therefore at risk. Data collected on 1101 cases of maternal tetanus in developing countries between 1958 and 1990 indicated that 27% were attributed to postabortal and 67% to postpartum sepsis. In southeastern Nigeria where abortion rates are high, a high proportion of girls were also seronegative for tetanus antibodies. Many unvaccinated pregnant women cite the lack of money for obtaining vaccination when obtaining prenatal services. The WHO is promoting vaccination of women of reproductive age by screening their tetanus toxoid status, but adolescents are poorly covered because they are not regular attenders. Expressly targeting girls would be feasible, as it would require 5 injections providing protection for life. Even 4 injections may protect for 20 years if delivered at the end of primary school. Thus a school health service delivering tetanus vaccination may improve the vaccination of adolescent girls. This could be combined with distribution of vitamin A and antihelminthics whereby the response to the vaccine could be improved significantly. In addition, it has also been suggested that a late dose of an acellular pertussis vaccine and a second dose of measles vaccine given in adolescence would reduce the pool of susceptible girls, just as girls have been targeted for rubella vaccination. Implementation of tetanus vaccination would require local schools vaccination days, immunization cards, high potency primary vaccination, and tetanus boosters free of charge with a system to monitor antibody responses.

To estimate the incidence of Haemophilus influenzae type b (Hib) invasive disease in Italian infants we performed a prospective study in a cohort of newborns enrolled for a randomized trial on safety and efficacy of three pertussis vaccines and followed for onset of serious disease or pertussis. The overall cumulative incidence observed in 15,601 children was 51.3/100,000 for all invasive Hib infections and 38.4/100,000 for Hib meningitis, over 27 months of observation. The incidence density of all invasive Hib disease was 28.7/100,000 person-years, while meningitis occurred with an incidence of 21.5/100,000 person-years. Among the eight cases detected, six were meningitis, one sepsis, and one cellulitis. The child with sepsis died. The incidence and epidemiology of invasive Hib disease in Italy are comparable to those reported from other European countries. Cost-benefit analyses are needed for planning Italian vaccination policy.

CS-834 is a prodrug of the carbapenem R-95867, developed by Sankyo Co., Ltd., Tokyo, Japan. To investigate the possibility that CS-834 may be the first carbapenem usable in an oral dosage form, its in vitro antibacterial activity (as R-95867) and in vivo antibacterial activity were compared with those of cefpodoxime proxetil, cefditoren pivoxil, cefdinir, ofloxacin, imipenem, and amoxicillin. R-95867 had high levels of activity against methicillin-susceptible staphylococci and streptococci, including penicillin-resistant Streptococcus pneumoniae, as well as Neisseria gonorrhoeae, Moraxella catarrhalis, the members of the family Enterobacteriaceae (with the exception of Serratia marcescens), Haemophilus influenzae, and Bordetella pertussis; for all these strains, the MICs at which 90% of tested strains are inhibited (MIC90s) were 1.0 microg/ml or less. Against methicillin-resistant staphylococci, enterococci, Serratia marcescens, Burkholderia cepacia, Stenotrophomonas maltophilia, and Acinetobacter calcoaceticus, R-95867 showed activity comparable to or slightly less than that of imipenem, with MIC90s ranging from 2 to >128 microg/ml. The in vivo efficacy of oral CS-834 against experimental mouse septicemia caused by gram-positive and gram-negative bacteria was better than that of comparative drugs. In murine respiratory infection models, the efficacy of CS-834 reflected not only its potent in vitro activity but also the high levels present in the lungs.

Effects of GTP-binding proteins on the activation of secretory phospholipaseA2 (sPLA2) and cytosolic phospholipaseA2 (cPLA2) in rat liver during two different phases of sepsis were studied. Sepsis was induced by cecal ligation and puncture (CLP). Experiments were divided into three groups: control, early sepsis, and late sepsis. Early and late sepsis refers to those animals sacrificed at 9 and 18 h, respectively, after CLP. The results show that in the absence of G-protein modulator, hepatic sPLA2 and cPLA2 activities were activated by 40.8-46 and 91.6-105.8%, respectively, during early and late phases of sepsis. GTPgammaS and fluoroaluminate (AlF4-) stimulated sPLA2 and cPLA2 activities within each experimental group, i.e., control, early sepsis, and late sepsis. The GTPgammaS and AlF4(-)-stimulated sPLA2 and cPLA2 activities remained significantly elevated during early phase (22.3-65.6% increase) and late phase (32.5-109.1% increase) of sepsis. Further analyses demonstrate that cholera toxin significantly stimulated sPLA2 and cPLA2 activities within each experimental group, and that the cholera toxin stimulated sPLA2 and cPLA2 activities remained significantly higher during early phase (23.5-37% increase) and late phase (56.7-70% increase) of sepsis. In contrast, pertussis toxin significantly inhibited sPLA2 and cPLA2 activities within each experimental group, and that the pertussis toxin-inhibited sPLA2 and cPLA2 activities remained significantly higher in early septic (57-68.5% increase) and late septic (34.6-45.5% increase) experiments. These data demonstrate that cholera toxin-sensitive G alpha s and pertussis toxin-sensitive G alpha i were both involved in the activation of sPLA2 and cPLA2 activities in rat liver during the progression of sepsis.

Decreasing of number of cases as well as incidence rate of hepatitis type B and type A, and increasing of pertussis, leptospirosis, encephalitis and some other diseases was noted in Poland in 1997. The biggest percentage of deaths was caused by tuberculosis--43.1%, sepsis--over 21.9% and hepatitis--10.6%. Introduction of ICD-10 as well as strikes of health workers in Poland in 1997 caused undernotification especially of deaths.

A 4-year retrospective study showing that we isolated Bordetella holmesii, but not Bordetella pertussis, from patients with pertussis-like symptoms was performed. From 1995 through 1998, we isolated B. holmesii from 32 nasopharyngeal specimens that had been submitted from patients suspected of having pertussis. Previously, B. holmesii had been associated mainly with septicemia and was not thought to be associated with respiratory illness. A study was undertaken to describe the characteristics of the B. holmesii isolates recovered and why we were successful in detecting the organism in nasopharyngeal specimens. B. holmesii isolates were characterized for drug sensitivities and for genetic relatedness by pulsed-field gel electrophoresis (PFGE). These isolates, an additional strain of B. holmesii isolated from a blood culture and previously confirmed by the Centers for Disease Control and Prevention, Atlanta, Ga., and 14 other clinical isolates of Bordetella spp., including 4 of B. bronchiseptica, 5 of B. parapertussis, and 5 of B. pertussis, were studied. They were all separately inoculated on three Bordet Gengou (BG) selective media containing either 0.625 microgram of oxacillin per ml, 40 microgram of cephalexin per ml, or 2.5 microgram of methicillin per ml, on BG agar with no antibiotic (control), and on charcoal agar (CA) with and without 40 microgram of cephalexin per ml. We found that cephalexin, the antibiotic commonly incorporated in both CA and BG agar for the recovery of Bordetella spp., is inhibitory to the growth of B. holmesii. In addition, the genotypic analysis of the 32 B. holmesii isolates by PFGE following restriction with XbaI and SpeI identified the dominant strains circulating during the study period.

Bordetella bronchiseptica rarely causes disease in man, and is an unusual pathogen in animals. It causes a pertussis-like syndrome, but pneumonia and sepsis have been described in the immunocompromised as well as in the immunocompetent. A 53-year-old man with adult-onset diabetes and healed pulmonary tuberculosis presented with lobar pneumonia and rapidly developed septic shock with adult respiratory distress syndrome. He responded well to the combination of piperacillin-tazobactam.

Klebsiella pneumoniae is a common cause of septicemia and urinary tract infections. The PCR-supported genomic subtractive hybridization was employed to identify genes specifically present in a virulent strain of K. pneumoniae. Analysis of 25 subtracted DNA clones has revealed 19 distinct nucleotide sequences. Two of the sequences were found to be the genes encoding the transposase of Tn3926 and a capsule polysaccharide exporting enzyme. Three sequences displayed moderate homology with bvgAS, which encodes a two-component signal transduction system in Bordetella pertussis. The rest of the sequences did not exhibit homology with any known genes. The distribution of these novel sequences varied greatly in K. pneumoniae clinical isolates, reflecting the heterogeneous nature of the K. pneumoniae population.
