Between 1981 and 1986 Listeria monocytogenes was isolated from blood cultures, CSF, meconium/stools or external swabs from 18 newborn infants of two neonatal intensive care units (ICU) in adjacent pediatric clinics of Dresden. The epidemiological and clinical data of infants and their mothers, as well as microbiological and laboratory, x-ray, EEG and ultrasonic findings, are presented. All infants had an early onset of their disease. Cases were classified as granulomatosis infantiseptica (three cases), sepsis (three cases), meningitis (eight cases) and listerial infection without distinct organ manifestations (four cases), respectively. As far as the predominant symptoms at admission were concerned, no typical clinical signs of neonatal listeriosis could be evaluated. Cases with manifest clinical infections had an overall mortality rate of 21% (3/14) despite the immediate initiation of antibiotic therapy; at discharge, a further five patients showed neurological residuals. Serotyping and phagetyping have proved to be methods for recognition or exclusion of epidemiological relationships.

Lumbar CSF eicosanoids were measured in 11 neonates with perinatal asphyxia and 12 neonates with suspected sepsis. In the asphyxia group low levels of thromboxane B2 and prostaglandin F2a were detected in five neonates, all of which had had a lumbar puncture prior to 4 hours of age. In the group with suspected sepsis two infants had positive blood cultures and one had strep meningitis. CSF eicosanoids were nondetectable in all patients in this second group with the exception of the infant with meningitis. With meningitis CSF eicosanoids were markedly elevated. These findings suggest that lumbar CSF eicosanoids do not appear to be a clinically useful tool. The data further suggest that eicosanoids are involved in the inflammatory response to meningitis.

With the object to determine the utility of C-reactive protein (CRP) in the diagnosis of neonatal sepsis. We proceeded to create the prospective study of cases and controls of newborn included in the study of neonatal sepsis in the Instituto Nacional de Perinatologia. We measured the seric CRP in samples obtained by capillary punction simultaneously with blood culture and/or CSF culture, for bacterial infection criteria. We included 64 newborn divided in two groups: 42 patients were not infected and 22 cases had positive cultures. The results in the uninfected newborn group of CRP were negative to positive dilutions 1:32; with the newborn infected the CRP had values of 1:32 to 1:2048. The probability to find values equal or major to 1:32 in the infected newborn with positive cultures the CRP have values of sensitivity of 91% and specificity of 93% to get this values. We accept that the CRP could be used systematically for the diagnosis of neonatal sepsis, being a simple procedure and accessible for use in the newborn with sepsis suspicion.

8 patients with bone marrow failure after a caesium-137 radiation accident were treated with recombinant human granulocyte-macrophage colony stimulating factor (rHuGM-CSF). The 7 who were evaluable had prompt increases in granulocytes and bone marrow cellularity. 2 patients died of radiation toxicity and haemorrhage and 2 of bacterial sepsis acquired before the start of rHuGM-CSF treatment. 4 patients survive, including 2 who were treated early and never became infected. This therapeutic approach to radiation-induced granulocytopenia may therefore be useful after radiation and nuclear accidents.

In a prospective study during the summer and fall of 1982, enterovirus was isolated from 48 hospitalized children; in 29 (60%) enterovirus was isolated from CSF or blood, and in 19 (40%) only a presumptive diagnosis was established. Blood was positive in 21 (44%) and was the only positive specimen in two children. A presumptive diagnosis was provided within 4 days of admission in 38 (80%) and within 48 hours in 19 (40%) of the children from whom enterovirus was isolated. Viremia was most often detected in febrile infants younger than 3 months of age with a clinical picture simulating bacterial sepsis. The presence of viremia was inversely related to the presence of CSF pleocytosis and to virus isolation from CSF. The diagnosis of diseases caused by enterovirus is more accurate when blood culture is added to CSF stool and throat cultures.

Of 849 CSF cultures done at Hartford Hospital, nine were positive for nonanthrax Bacillus species. Differentiation of true nonanthrax Bacillus species infection from contamination requires careful consideration of the clinical findings, the clinical course, and the laboratory data. In seven patients the nonanthrax Bacillus species represented contamination. In two patients the nonanthrax Bacillus species represented true infection. In one of these infected patients, nonanthrax Bacillus species complicated a cranial gun shot wound. Bacillus cereus meningitis developed in the second patient, a premature infant, following sepsis from a contaminated IV catheter. Nonanthrax Bacillus species, especially B cereus, can be resistant to penicillins and cephalosporins when nonanthrax Bacillus species infections are being treated, susceptibility testing should always be performed.

We evaluated fever in 342 hospitalized infants less than 8 weeks of age. Sixteen infants (5%) had bacteremia or bacterial meningitis. Fifty-two percent of the infants were admitted during the months of July through September. We found no significant relationship between season, sex, height of fever, or erythrocyte sedimentation rate and the recovery of bacteria from the blood or CSF. A WBC less than or equal to 5,000/cu mm or a ratio of immature to total neutrophils greater than or equal to 20% correlated significantly with bacteremia or bacterial meningitis, though the sensitivities of these tests were unacceptably low. Prospectively, of 61 infants whose clinical appearance did not suggest sepsis, none had bacterial pathogens in the blood or CSF, whereas four of 36 infants with a septic appearance did have pathogens. Recent investigations support the initial clinical impression as important in assessing these febrile infants. We found that bacteremia is more likely to occur in infants less than 4 weeks of age (8%) than in the older infants (2.9%).

The results presented in this paper demonstrate that recombinant human granulocyte-colony stimulating factor (rhG-CSF) is a potent myelopoietic growth and differentiation factor in vivo. RhG-CSF was able to shorten the time period of neutrophil recovery in both cyclophosphamide (CY)-induced myelosuppression and following bone marrow transplantation (BMT) in primates. Its ability to significantly shorten the period of chemotherapy-induced bone marrow hypoplasia may allow clinicians to increase the frequency or dosage of chemotherapeutic agents. In addition, the increase in absolute numbers of functionally active neutrophils may have a profound effect on the rate and severity of neutropenia-related sepsis. Furthermore, the activities reported here indicate a potential role for rhG-CSF in the treatment of patients with myelodysplastic syndrome, congenital agranulocytosis, radiation-induced myelosuppression, and after bone marrow transplantation.

We examined the in vivo effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) in primates (cynomolgus monkeys) treated with subcutaneous doses of rhG-CSF for 14-28 d. A dose-dependent increase in the peripheral white blood cells (WBC) was seen, reaching a plateau after 1 wk of rhG-CSF treatment. The elevation of WBC was due to an increase in the absolute neutrophil count. These results demonstrate that rhG-CSF is a potent granulopoietic growth and differentiation factor in vivo. In cyclophosphamide (CY)-induced myelosuppression, rhG-CSF was able to shorten the time period of WBC recovery in two treated monkeys to 1 wk, as compared to more than 4 wk for the control monkey. Its ability to significantly shorten the period of chemotherapy-induced bone marrow hypoplasia may allow clinicians to increase the frequency or dosage of chemotherapeutic agents. In addition, the increase in absolute numbers of functionally active neutrophils may have a profound effect in the rate and severity of neutropenia-related sepsis. Furthermore, the activities reported here indicate a potential role for rhG-CSF in the treatment of patients with myelodysplastic syndrome, congenital agranulocytosis, radiation-induced myelosuppression, and bone marrow transplantation.

Between January of 1983 and December 1984, 11 strains of pneumococci resistant to penicillin were isolated, from a total of 46 strains studied with clinical signification, thus accounting for 23.9%. In nine cases (19.5%) pneumococci showed partial resistance to penicillin and in two strains (4.3%) resistance was total. Pneumococcal disease in our 11 patients was demonstrated by blood culture in 7 cases and by culture of the CSF, in 4. Diagnosis of the patients were as follows: 4 sepsis in immunosuppressed host, 2 bacteremia without an evident focus, 1 pneumonia, 3 meningitis and 1 ventriculitis. Vancomycin and rifampin are the most active in this cases. Some of the new cephalosporins of the third generation (cefotaxime and ceftriaxone) and cefuroxime have a good activity in vitro and a good passage to the CSF.
