146 cases of severe sepsis due to gram negative microbials in adult with average age of 54.14. The incidence of community infections(95.2% vs 4.8%). The mortality in general group is 46.6% and in shock group is 72.1%. Many criteria for determining the poor prognosis are: (1) Salmonella spp, Pseudomonas spp, (2) underlying diseases such as HIV/AIDS, Cushing syndrom, (3) Complications (septic shock, acute renal failure and DIC). Effective antibiotic groups to almost Gr(-) organismes include: Cephalosporin III, Oflocet, Amikacin and Netilmicin. The combination of an Aminoglycoside and a Cephalosporin III (or Oflocet or Imipenem) for empirical treatment is usually appropriate.

BACKGROUND: Previous antibiotic exposure may inhibit the growth of microorganisms in blood culture bottles. The authors investigated the frequency of previous antibiotic usage and analyzed the relationships among antibiotic usage, microbiological culture results and mortality of sepsis patients. METHODS: From April to May 2011, all blood cultures requested from inpatients were analyzed according to the admitted ward and antibiotic prescription records. The BacT/Alert 3D system (bioMerieux Inc.) was used with a standard bottle (SA, SN) for blood culture. RESULTS: Of 900 inpatients, 48% had been receiving antimicrobial agents when blood cultures were ordered. This group had a significantly higher mortality rate (36.2%) compared to the patients who had not received antibiotics (11.1%). Gram-negative rod bacteremia (37.1%) and candidemia (100%) resulted in a significantly higher mortality rate compared to Gram-positive cocci bacteremia (16.4%). In the analysis of 21 cases resulting in death, 15 (71.4%) patients died before or on the date when blood culture results were reported. CONCLUSION: Patients who receive antibiotics prior to blood collection may be at a higher risk for mortality. In the present study, Gram-negative rod bacteremia and candidemia cases showed a rapid progression of sepsis as indicated by Gram staining and thus should be regarded seriously.

Candidemia is a major cause of nosocomial morbidity and mortality in neonates. Prompt diagnosis and treatment is crucial. Risk factor analyses have been conducted worldwide, but limited local data are available. This study was conducted to help pediatricians practicing locally decide when to suspect if a neonate has candidemia; therefore, helping them in the judicious use of empirical antifungal therapy. Objective: To determine if there was a difference in the risk factors among neonates with candidemia and those without it, who were admitted at the Neonatal Intensive Care Unit of the Philippine General Hospital from October 2003 to August 2006. Methods: Neonates admitted within the mentioned period, surviving at least on the third day of life, and had at least one blood culture on or after day 3 of life were included in the study. A retrospective review of records was performed to identify the presence or absence of known risk factors for candidemia. The outcome of interest was the presence of candidemia. Each variable was analyzed initially using the bivariate analysis chi-square. Cut-off value for inclusion into multivariate analysis was p<0.25. Multivariate analysis, through backward elimination, was done to narrow down independent variables (p value for retention <0.25). Results: One hundred thirty-eight neonates (69 cases and 69 controls) were included. Based on bivariate analysis, patients exhibiting the following characteristics showed increased risk for candidemia: birth weights of 1250 to 1499g (OR: 3.24; 95% CI: 1.04-10.07) and 1500 to 2449g (OR: 3.84; 95% CI 1.31-11.27); pediatric aging < 28 weeks (OR: 1.42; 95% CI: 1.07-8.5) and 28 to 32 weeks (OR: 1.89; 95% CI: 0.74-4.84); central vascular access (OR: 0.52; 95% CI: 0.26-1.03); prolonged broad-spectrum antibiotic use (OR: 2.0; 95% CI: 0.95-4.2); and increased hospital stay (OR: 0.5; 95% CI: 0.24-1.05). Intralipid use was also associated with candidemia, but was excluded due to insufficient data available. In the multivariate analysis, only patients with birth weights of 1500 to 2449g (OR: 3.65; 95% CI: 1.24-10.77) and 1250 to 1499g (OR: 3.24; 95% CI: 1.04-10.07) qualified. A clinical predictive model in diagnosing candidemia was not possible due to insufficient variables available. Conclusion: Based on the study, infants with lower birth weights (<2500 g) were at most risk for developing subsequent candida infection.

To study the pathogens incidences in cord blood and the efficiency of different detective methods, 60 samples were drawn and reserved from collected and processed cord blood, respectively. The BACTEC 9050 system, improved Martin/thioglycollate broth (22 degrees C) and thioglycollate broth (35 degrees C) were employed to detected bacteria (including fungus) at the same time. Two hundred and six cord blood serum samples were used to detect the HBV DNA and HCV RNA by molecular biology technique, HBsAg, Anti-HBC, Anti-HCV, Anti-HCMV-IgM, HTLV-1, HTLV-2, HIV-1 and HIV-2 by ELISA and RBC agglutination test were used to detect the TPHA. Results showed that using BACTEC 9050 system, the incidence of bacteria and fungus was 3.33% and 0% respectively in collected cord blood; in processed cord blood, the rates increased to 6.67% and 1.67%, respectively. The sensitivity of BACTEC 9050 was higher than that of Martin/thioglycollate broth (22 degrees C/35 degrees C) culture. In 206 serum samples, the positive rate of HBV DNA was 5.8%, HCV RNA was 2.4%, HBsAg was 2.4%, HCMV-IgM was 1.89%, HCV was 2.4% and Anti-HBC was 29.4%. In those samples that Anti-HBC was positive, the positive rate of HBV DNA was 6.7%. It was concluded that the incidences of microbiological contamination in cord blood were high. The routine culture system would lead to false negative results of obligate anaerobes. It was necessary to replace the current culture system with improved system, such as BACTEC 9050 system. The molecular biology technique would make up for the default of ELISA.

BACKGROUND: Catheter-related sepsis (CRS) has become an important cause of nosocomial infections and the major complication with the intravenous central venous catheter (CVC) use. In this paper, we present the culture results of two years from Chonnam National University Hospital on the etiologic agents of CRS. METHODS: We reviewed the culture results for the most recent two years (July 1999 to June 2001) including semiquantitative CVC tip cultures (n=622) and differential quantitative blood cultures (n=149), as well as hospital records to determine clinical correlates of CRS. CRS was defined as a positive blood culture and catheter culture with the same organism in conjunction with a CVC tip >or=15 CFU or a central-to-peripheral blood culture colony count ratio of >or=5 :1. RESULTS: Forty-two (6.8%) of 622 CVC tip cultures and 13 (8.7%) of 149 differential quantitative blood cultures were associated with CRS. A total of 48 (32.0%) of 150 patients with bacteremia or candidemia were confirmed as having CRS, using semiquantitative tip cultures (30.9%, 42 of 136) and/or differential quantitative blood cultures (27.1%, 13 of 48). Twenty-one (48.8%) of 43 candidacies patients were associated with CRS and were more frequent than bacteremia due to Gram-positive cocci (27.3%, 18 of 66), and Gram-negative bacilli (23.1%, 9 of 39)(P<0.05). In 48 cases with proven CRS, Candida parapsilosis (29.2%) and Staphylococcus aureus (25.0%) were the most common etiologic agents, followed by coagulase negative Staphylococcus (10.4%), and Acinetobacter baumannii (8.3%). CONCLUSIONS: In culture proven cases of CRS, C. parapsilosis and S. aureus were the predominant causative organisms, and candidemia was more frequently associated with CRS than was bacteremia.

This study introduced the serum types of p.aeruginosa that found commonly in the septicemia due to the burn. The times of septicemia, relatives factor and evaluate ion of the antibiotic resistance of P. aeruginosa. The results found that the septicemia occurred frequently in the deep wide burn and wet thermal burn. The septicemia was direct proportional with the amount of bacterial/area of burn. The septicemia occurred frequently in the third to fifth days of the burn

The burn related septicaemia were a major complication in burn infection with mortality is very high. Research on 203 patients who suspected burn related septicaemia were given emergency at The National Institute for Burn from June, 1996 to Feb, 1997 suggested that bacterial were found 42/203 (20,72%), bacteria were isolated, that are P. aeruginosa (69,05%), S.aureus (21,43%), mortality of septicaemia patients were 32/42 (76,19%). Among them P. aeruginosa induced 23/32 (71,19%). There are very high correlation between bacteria induced septicaemia and burn infection. Rate of burn septicaemia increase with amount of bacteria in 1 square cm of burn, deep level of burn and large area of burn. Burn septicaemia occurs mostly after 2 weeks.

We investigated the combined effect of glutamine (GLN) and growth hormone (GH) on bacterial translocation (BT) in sepsis. After single intraperitoneal injection of lipopolysaccharide (10 mg/kg), 48 rats were divided randomly into four groups of 12 animals each: the control group received chow orally; the GLN group received chow plus 10% GLN; GH group received chow plus GH; and the GLN/GH group received chow, 10% GLN, and GH. Twenty-four and 96 hr later, rats were sacrificed. Portal blood culture, bacterial colony counts of cultured mesenteric lymph nodes, mucosal thickness, malondialdehyde (MDA), and glutathione (GSH) levels in the gut mucosa were measured. There was no significant change of the rate of portal blood culture between all treatment groups at 24 and 96 hr. At 24 hr, the rats receiving combined treatment of GLN and GH showed lower bacterial colony counts and mucosal MDA levels than the control rats, and higher mucosal GSH levels than the control and GLN-treated rats. At 96 hr, rats treated with both GLN and GH exhibited lower bacterial colony counts and mucosal MDA levels, and higher mucosal thickness and GSH levels than control, GLN, or GH-treated rats. This study suggests that the combination of GLN and GH may synergistically reduce BT over time in sepsis.

Klebsiella pneumonia is an opportunistic pathogen that can lead to severe diseases such as septicemia, pneumonia, urinary and hepatobiliary track infection, in mainly hospitalized, immunocompromised patients. It has been reported to produce cellulitis, ecthyma gangrenosum in cutaneous manifestions, which are more commonly induced by bacteremia and spreading from other internal organs than primary inoculation. Herein, we present a case of a 75-year-old man with aplastic anemia, which progressed to septic shock and secondary cutaneous infection caused by Klebsiella pneumonia, but showed similar skin lesions to systemic fungal infection with dispersed erythematous macules and vesicular change on the center of his erythema.
