One thousand and ten miscellaneous samples collected from infected newborns, were tested at the bacteriology laboratory of A. Royer Children's Hospital from 1983 to 1991. These samples included 471 blood cultures, 114 pus of various origins, 410 cerebrospinal fluids and 15 urines. One bacteria or bacterial soluble antigens were detected in 294 samples (29.2%). Positivity percentage was 29.2% for septicemia, 68.4% for suppurations, 17.8% for meningitidis and 33.3% for urinary tract infections. Altogether, we isolated 156 enterobacteria (53%), 14 Gram negative bacilli (4.7%) and 124 cocci (42.1%) among them 19 streptococci (A, B, C) and 25 pneumococci. Three major species were identified: S. aureus (25.8%), Klebsiella spp (19.7%) and Escherichia coli (14.6%). The most efficient antibiotics against all strains were AKN, CTX, CRO and GEN.

Cyclophosphamide (CTX) 600 mg/m2, carboplatin 280 mg/m2, and cisplatin 50 mg/m2 were administered on day 1 every 4 weeks to 41 previously untreated ovarian cancer patients with residual disease greater than 2.0 cm after primary laparotomy. Of 22 patients with measurable disease treated with up to eight cycles of therapy, the overall clinical response rate was 73% (exact 95% confidence interval [CI], 50% to 89%), with 50% complete response (CR). Six of 11 clinical CR (cCR) patients underwent surgical restaging; three pathologic CRs (pCRs) and three pathologic partial responses (pPRs) with residual disease less than 2.0 cm were documented. Fourteen patients had nonmeasurable but assessable disease; the clinical response rate was 57% (Cl, 29% to 82%) with two (14%) CRs. Second-look surgery was performed in one of the two cCR patients; a pPR was documented. Five patients with nonassessable disease were stable during chemotherapy; two underwent surgery and had pCRs. The median time to treatment failure (TTF) was 14.8 months, and median survival for the 41 patients is 26.7 months. Overall, 37% of the patients had progression-free intervals of at least 2 years, and 27% have survival times in excess of 3 years. Hematologic toxicity was substantial but manageable, with 58% and 66% experiencing a granulocyte nadir less than 500/microL and a platelet nadir less than 50,000/microL, respectively. One treatment-associated fatality occurred as a result of leukopenic sepsis and renal failure in the setting of progressive disease and ureteral obstruction. Mild to moderate nausea and vomiting occurred in most patients, but none experienced severe ototoxicity or peripheral neuropathy. Over all courses, 73% of the projected dose intensity of CTX and carboplatin and 86% of cisplatin were delivered. Since granulocytopenia and thrombocytopenia were dose-limiting, the addition of colony-stimulating factors that support both myeloid and megakaryocyte precursors may permit further dose intensification.

A prospective neoadjuvant trial utilizing chemotherapy (CTX) and radiotherapy (XRT) prior to pancreatectomy was established to determine the feasibility of resection after aggressive pretreatment and its effect on survival. Fifteen patients with pancreatic cancer (14 head, 1 body) and 1 patient with duodenal cancer, (with paraaortic adenopathy), were subjected to combination treatment with infusional 5-FU, bolus injection of mitomycin-C, and XRT (4 patients were treated off the protocol). Patients were restaged 3 wk after XRT, and those deemed resectable underwent a pancreatic resection. Three patients did not undergo exploration after the neoadjuvant therapy, although two of these were deemed resectable by CT scan. The remaining 13 patients underwent exploration and 10 underwent resection. Three did not undergo resection because of extrapancreatic disease, although their primary tumors were resectable. One patient had no residual tumor in the specimen. The others had residual tumor with evidence of necrosis and hyalinization, but all margins were free of tumor. There were two perioperative deaths from sepsis. Of the remaining patients who underwent resection, one died of a myocardial infarction at 9 mo. One patient died with recurrent disease at 19 mo. The remaining patients are alive 40, 32, 11, 11, 10, and 4 mo since diagnosis and are currently free of disease. Aggressive neoadjuvant chemoradiotherapy can be performed safely, allows successful resection, and may yield long-term survival or curve.

Forty-two men with urinary tract infection and benign prostatic hyperplasia were randomized into two groups before transurethral resection. One group (22 patients) received Claforan (cefotaxime) peroperatively and thereafter daily for five days. In the other group (20 patients), Hiprex (methenamine hippurate) was given daily from the day before the operation, for a total of six days. All the bacterial isolates were sensitive to cefotaxime. The efficacy of the medication was clinically and bacteriologically evaluated. Postoperative temperature elevation (greater than 38 degrees C) occurred in one of the 22 patients in the cefotaxime group, and in nine of the 20 in the methenamine hippurate group (p less than 0.05). None of the former group, but two patients in the latter, had septicemia. The difference was not statistically significant. The response to treatment was satisfactory in 13 of the 22 patients in the cefotaxime group, but in only one of the 20 treated with methenamine hippurate (p less than 0.005). Antibiotic treatment is recommended for bacteriuric patients undergoing transurethral prostatic resection.

Patients with malignant astrocytoma continue to respond poorly to chemotherapy and have a dismal prognosis. Cyclophosphamide (CTX) and etoposide demonstrate activity against malignant astrocytoma at standard dosages, with bone marrow suppression as the limiting toxicity. In order to allow dose intensification, minimize leukopenia, and improve efficacy granulocyte colony-stimulating factor (G-CSF) was used in combination with CTX and etoposide. The protocol consisted of CTX (2 mg/m2/d, days 1, 2), etoposide (200-300 mg/m2/d, days 1-3), and G-CSF (5-10 micrograms/d subcutaneously, days 4-18), every 4 weeks. Nine evaluable patients (7 glioblastoma multiforme, 2 anaplastic astrocytoma) were treated, ranging in age from 26-67 (mean 41). One of 9 patients responded (11%) with a partial response (13+ months), 3 had stable disease (33%; 8, 5, 2.5 months), and 5 had progressive disease (3, 2.5, 2, 1.5, 1 months). The median time to progression for responders was 6.5 months, while overall it was 2.5 months. Overall median survival was only 7.0 months. Toxicity was frequent and severe, typically delaying treatment cycles. The most common complications were severe myeolosuppression (9), sepsis (8), rash (6), urinary infection (5), and anorexia (5). Treatment delays caused by infections and other complications occurred often, abrogating the intended dose intensification. The received dose intensity (DI) for CTX was 400-425 mg/m2/week (relative DI 0.41), while for etoposide it was 75 mg/m2/week (relative DI 0.42). In summary, as used in this protocol, dose intensive chemotherapy with CTX, etoposide, and G-CSF does not improve efficacy over standard regimens and results in excessive toxicity.

Acute lung injury and the acute respiratory distress syndrome (ARDS) are significant causes of morbidity and mortality following sepsis and hemorrhage. Increased IL-1beta production in the lung is important in the development of acute inflammatory lung injury. Although neutrophils are an important component of the inflammatory response that characterizes acute lung injury, there is little information to suggest that they are capable of initiating cytokine-mediated immune responses in the lung. To explore the role of neutrophils in the early stages of acute lung injury, we examined IL-1beta production by mouse lung neutrophils after hemorrhage and endotoxemia. There was a significant increase in IL-1beta expression among intraparenchymal pulmonary neutrophil/mononuclear cells (IPNMC) 1 h after hemorrhage or endotoxemia. IL-1beta was detected only in a neutrophil-rich fraction of the IPNMC, but not in T and B lymphocytes positively selected from the IPNMC. Cyclophosphamide (CTX)-treated neutropenic mice expressed significantly less IL-1beta in IPNMC after hemorrhage or endotoxemia compared with CTX-untreated controls. Immunohistochemical analysis of lung sections from mice after hemorrhage or endotoxemia revealed IL-1beta expression in infiltrating neutrophils. These data indicate that IL-1beta-producing neutrophils traffic to the lungs rapidly in response to hemorrhage or endotoxemia and support the concept that proinflammatory cytokine production by lung neutrophils may contribute to the development of lung injury after blood loss and sepsis.

An interim report evaluating the feasibility of myeloablative therapy followed by peripheral blood stem cell (PBSC) autotransplant in patients aged >60 years is presented. In the last 2 years 19 patients >60 years old with several oncological conditions, mostly hematological, underwent PBSC autotransplant either as salvage therapy following relapse or resistance to conventional treatment, or as consolidating therapy as a part of a well defined protocol. There were 13 males and six females; the mean age was 66.9 years (range 61-76 years); nine patients had resistant or relapsed lymphoma, six myeloma, two acute leukemia, one Waldenstrom's disease and one lung cancer. Myeloablative schemes included BEAM exclusively for lymphomas, busulfan and melphalan (Bu-MPH) mainly for myeloma, busulfan and cyclophosphamide (Bu-CTX) for lymphomas and leukemia and VP-16 and CTX for lung cancer. Mobilization of CD34+ cells was achieved in all patients with the combination of high-dose CTX and G-CSF with collections between 2.83 to 19.04 x 10(6)/kg (mean 7.1). All patients engrafted with a median time for recovery of PMN (>0.5 x 10(3)/microl) of 10 days (range 8-12 days) and for PLT (>20 x 10(3)/microl) of 12 days (range 10-17 days). Major responses were obtained in 15 of 16 patients evaluable for response and eight patients entered CR; overall eight patients are in CR, five are alive with disease, five are dead from disease progression and one is dead because of congestive heart failure 7 months following PBSC autotransplant. No early deaths following the procedure occurred; major side-effects were grade I-II mucositis (58%), fever with documented sepsis (10%), pneumonia (5%), cardiac, renal and liver toxicity (5%). Cardiac function was evaluated before and after myeloablative therapy by VEF in all patients; no significant modifications were necessary. In conclusion, our experience demonstrates that myeloablative therapies in older selected patients can be feasible; the feasibility of introducing PBSC autotransplantation following myeloablative therapy as a front-line treatment in patients aged >60 years, needs accurate guide lines for selection of appropriate patients.

A cefotaxime-resistant, ceftazidime-susceptible Escherichia coli isolate was obtained from a patient with sepsis in 1997, from which a beta-lactamase with a pI of 8.1 was cloned. Cephaloridine and cefotaxime relative hydrolysis rates were 167 and 81, respectively (penicillin G rate = 100), whereas ceftazidime hydrolysis was not detected. The nucleotide sequence revealed a bla gene related to that coding for CTX-M-3. Despite 21 nucleotide substitutions, only 2 determined amino acid changes (Ala27Val and Arg38Gln). The amino acid sequence identity between this enzyme, designated CTX-M-10, and the chromosomal beta-lactamase of Kluyvera ascorbata was 81%.

The emergence of resistance to antimicrobial agents within the salmonellas is a worldwide and severe problem. A case of treatment failure due to the emergence of resistance to ceftriaxone in Salmonella enterica serotype Anatum was studied. S. enterica serotype Anatum and Escherichia coli, both of which are susceptible to ceftriaxone, were initially isolated from a diabetic patient hospitalized for the treatment of wound and urinary tract infections. Resistant S. enterica serotype Anatum and E. coli strains were isolated concomitantly 2 weeks after the initiation of ceftriaxone therapy. The patient eventually died of a sepsis caused by the ceftriaxone-resistant salmonella. PCR, nucleotide sequence analysis, and DNA-DNA hybridization identified a bla(CTX-M-3) gene located on a 95.1-kb plasmid from the ceftriaxone-resistant isolates of S. enterica serotype Anatum and E. coli. The plasmid was proved to be conjugative. Molecular fingerprinting showed that the susceptible and resistant strains were genetically indistinguishable. The emergence of resistance to ceftriaxone in S. enterica serotype Anatum was due to the in vivo acquisition of a plasmid containing the bla(CTX-M-3) gene and was the cause for treatment failure in this patient.

Over a 6-year period (1997 to 2002), 56 strains of Proteus mirabilis (12% of the total number of P. mirabilis isolates obtained) resistant to ampicillin, piperacillin, cefazolin and cefoperazone by routine antimicrobial testing method, were isolated in Saitama Medical School Hospital. Of the 56 strains resistant to 4 beta-lactams, 12 strains were studied and were found to produce extended-spectrum beta-lactamases, identified as CTX-M-10 group and Toho-1 group in 8 and 2 strains, respectively. Susceptibility testing showed that 12 strains were resistant to cefotaxime, and cepodoxime, and ceftriaxon but susceptible to ceftazidime. Moreover, all of the beta-lactamases were inhibited by clavulanic acid. Of the 12 strains, one strain showed resistance to cephamycins such as cefoxitin, cefmetazole and cefotetan. Four of the twelve patients had infections caused by ESBL producing P. mirabilis, and eight patients were colonized, as confirmed by clinical and laboratory findings. The infections were urinary tract infections (two episodes), pneumonia (one episode), and sepsis (one episode). These patients had a favorable response to antibiotic therapy including cephalosporin. From these findings, CTX-M-type beta-lactamase producing P. mirabilis strains were confirmed from clinical specimens in our hospital.
