OBJECTIVE: To explore the risk factors for septic shock in patients with solid organ transplantation and complication of bacteremias. METHODS: Clinical data of 98 solid organ transplant cases with complication of bacteremias were retrospectively studied. All episodes of bacteremias met the CDC criteria. Six possible risk factors contributing to septic shock were evaluated by univariate analysis and multivariate logistic regression analysis. RESULTS: Among the 98 patients, 133 times of bacteremias have been reported and 39 patients developed septic shock. Among the 39 patients with septic shock, 43.5%, 38.5%, 15.4% and 2.6% of bacteremias were induced by multiple bacteria, gram-negative bacteria, gram-positive bacteria and fungi, respectively. The lung was the main source of bacteremias (41.8%), followed by intraabdominal/ biliary focus (24.5%). Risk factors for developing septic shock included the bacteremias happened in the 2nd to 8th week post transplant (P=0.014), polymicrobial etiology (P=0.001), intra-abdominal/ biliary focus (P=0.011), and liver transplant (P=0.002). Only bacteremias occurred in the 2nd to 8th week post transplant and polymicrobial etiology were significant risk factors by multivariate analysis. CONCLUSION Risk factors for developing septic shock in bacteremias after SOT are early-onset (the 2nd-8th week post transplant) and polymicrobial etiology.

Morganella morganii is a facultative gram-negative and anaerobic rod. It may be a cause of devastating infections in neonates and immunocompromised hosts. Some bacterial infections such as Clostridium and Vibrio are associated with hemolysis. However, massive hemolysis caused by M. morganii sepsis has not yet been reported. We observed a 59-yr-old man who had chemotherapy-induced neutropenia and was found to have massive hemolysis and metabolic acidosis due to sepsis. He died 6 hr after admission in spite of aggressive treatment. Two sets of blood cultures revealed the growth of M. morganii. We report here that M. morganii sepsis can cause fatal massive hemolysis leading to death.

BACKGROUND: This study was conducted to evaluate the risk factors for infection and clinical outcomes of bacteremic spontaneous bacterial peritonitis (SBP) due to ESBL-producing E. coli and K. pneumoniae, in patients with advanced liver cirrhosis. METHODS: The ESBL production was determined by NCCLS guidelines and/or double-disk synergy tests, on stored E. coli and K. pneumoniae blood isolates collected between 1998 and 2002. Of the patients with advanced liver cirrhosis, 15 case patients, with SBP due to ESBL-producers, were compared with 30 matched controls, with SBP due to non-ESBL-producers. RESULTS: There were no significant differences in age, sex, Child-Pugh scores, or APACHE II scores between the two groups. Significant factors associated with infection by ESBL-producing organisms, according to univariate analysis, were: ICU care, indwelling urinary catheter, central venous catheterization, an invasive procedure within the previous 72 hours, and prior use of antibiotics within the previous 30 days. When assessing the clinical response at 72 hours after the initial antimicrobial therapy, the treatment failure rate was significantly higher in the ESBL group (73.3% vs. 16.7%, p< 0.001). Also, overall 30-day mortality rates were 60% (9/15) in the ESBL groups and 23.3% (7/30) in the control group (p=0.015). CONCLUSION: Among patients with advanced liver cirrhosis, bacteremic SBP due to ESBL-producing E. coli and K. pneumoniae was associated with adverse outcomes, and significantly higher mortality.

We describe a case of septic shock due to Vibrio alginolyticus presenting with fever and bilateral leg pain. Despite intensive management with antibiotics and inotropic agents, the patient died from septic shock 1 day after hospitalization. V. alginolyticus was isolated from both leg wounds and a blood culture. To the best of our knowledge, this is the first reported case of V. alginolyticus bacteremia in Korea.

OBJECTIVETo study the relationship between the degree of fever within 48 hours of admission and the prognosis in children with bacterial bloodstream infection.

METHODSThis study retrospectively analyzed the clinical data of all patients diagnosed with sepsis who were admitted to the pediatric intensive care unit (PICU) of Shengjing Hospital Affiliated to China Medical University between September 2008 and September 2016. The children with bacterial bloodstream infection were classified into 5 groups according to the maximum temperature within 48 hours of admission: <36.5°C group, ≥36.5°C group (normal control), ≥37.5°C group, ≥38.5°C group, and ≥39.5°C group. The mortality was compared between the five groups. Results A total of 213 children with bacterial bloodstream infection were enrolled, consisting of 5 cases in the <36.5°C group, 44 cases in the ≥36.5°C group, 73 cases in the ≥37.5°C group, 69 cases in the ≥38.5°C group, and 22 cases in the ≥39.5°C group. A total of 48 cases died among the 213 patients. A significant difference was observed in the mortality between the five groups (P<0.01). The <36.5°C group and ≥39.5°C group had significantly higher mortality than the normal control group. However, there were no significant differences in the mortality between the ≥37.5°C and ≥38.5°C groups and the normal control group. Conclusions In children with bacterial bloodstream infection, those with a maximum temperature below 36.5°C or above 39.5°C within 48 hours of admission have a significantly increased mortality.
