OBJECTIVES: To study the clinical characteristics and risk factors of pyogenic liver abscess complicated by sepsis in children. METHODS: A retrospective analysis was conducted on the clinical data of 120 children with pyogenic liver abscess admitted from May 2004 to January 2024. According to the presence of sepsis, the children were divided into a sepsis group (82 cases) and a non-sepsis group (38 cases). The clinical characteristics of the two groups were compared, and risk factors associated with the occurrence of sepsis were identified. RESULTS: Among the 120 children with pyogenic liver abscess, 68.3% (82/120) had sepsis. Multivariate logistic regression analysis showed that fever, elevated white blood cell count, and decreased albumin level were closely associated with the occurrence of sepsis (P<0.05). Receiver operating characteristic curve analysis indicated that white blood cell count and albumin levels had significant predictive value for sepsis (P<0.05), and the combination of white blood cell count and albumin level showed higher predictive value for sepsis than the albumin level alone (P<0.05). CONCLUSIONS The clinical manifestations of children with pyogenic liver abscess complicated by sepsis are non-specific. Fever, elevated white blood cell count, and decreased albumin level are risk factors for sepsis in children with pyogenic liver abscess. Clinically, for children with unexplained fever and imaging suggestive of liver abscess, pyogenic liver abscess should be considered. If laboratory tests show elevated white blood cell count and decreased albumin level simultaneously, there should be a high level of suspicion for the development of sepsis.

BACKGROUND/AIMS: Pyogenic liver abscess (PLA) is a life-threatening condition, despite advances in diagnostic technology and strategies for treatment. A strong predictor of mortality in this condition is septic shock. This study describes clinical, biochemical, and radiologic features in patients with PLA with or without septic shock, with the intent of describing risk factors for septic shock. METHODS: Of 358 patients with PLA enrolled, 30 suffered septic shock and the remaining 328 did not. We reviewed the medical records including etiologies, underlying diseases, laboratory, radiologic and microbiologic findings, methods of treatment and treatment outcomes. RESULTS: The case fatality rate was 6.1%. In univariate analysis, the presence of general weakness, mental change, low platelet level, prolonged PT, high BUN level, high creatinine level, low albumin level, high AST level, high CRP level, abscess size >6 cm, the presence of gas-forming abscess, APACHE II score ≥20, and the presence of Klebsiella pneumoniae infection were significantly associated with septic shock. Multivariate analysis showed the presence of mental change (p=0.004), gas-forming abscess (p=0.012), and K. pneumoniae infection (p=0.027) were independent predictors for septic shock. CONCLUSIONS: The presence of mental change, gas-forming abscess, and K. pneumoniae infection were independent predictors for septic shock in patients with PLA.

PURPOSE: The aim of this study was to describe clinical, biochemical, and radiologic features in patients with pyogenic liver abscess and to investigate predictors of septic shock. METHODS: We consecutively included subjects who were diagnosed as pyogenic liver abscess in the emergency department (ED) from January 1st, 2010 to June 30th, 2013. Through review of medical records, clinical, biochemical, and radiologic data were collected. The primary endpoint was septic shock during hospitalization. RESULTS: A total of 228 patients were included, with a mean age of 60.8+/-12.8 years, and 63.2% were men. Among them, 198 patients presented with fever and GCS <15 was observed in 15. Klebsiella spp. was most commonly identified in 33.8%, followed by E. coli and Streptococci spp. in 7% for each. Septic shock occurred in 55 (22.4%) and mortality rate was 1.3%. In univariable logistic regression, GCS <15, systolic BP <90 mmHg, pulse rate > or =120/min, respiratory rate > or = 22/min, body temperature (BT) > or =38degrees C, WBC, platelet, BUN, creatinine, albumin, AST, alkaline phosphatase (ALP), Creactive protein (CRP), abscess size > or =5 cm, and bilobal involvement were significantly associated with septic shock (p<0.05). In multivariate analysis, systolic BP <90 mmHg (OR 95.79, 95% CI: 11.16-822.02), BT > or =38degrees C (OR 1.95, 1.36-2.78), BUN (OR 1.03, 1.01-1.06), ALP (OR 1.003, 1.000-1.005), and abscess size > or =5 cm (OR 2.31, 1.08-4.94) were independent predictors of septic shock. CONCLUSION: Low Systolic Bp, High Bt, Elevated Bun And Alp, And Abscess Size > or =5 Cm Were Independently Associated With Septic Shock In Patients With Pyogenic Liver Abscess.

BACKGROUND/AIMS: Pyogenic liver abscess remains a major diagnostic and therapeutic challenge, despite advances in diagnostic technology and new strategies for treatment. This study was conducted to compare the differences in clinical features and outcomes of pyogenic liver abscess according to age. METHODS: In total, 166 patients were enrolled and included 63 (<65 years old, group I), 62 (65-74 years old, group II), 41 (>75 years old, group III) patients in each group. We reviewed the medical records retrospectively including etiology, underlying diseases, characteristics of the liver abscess, laboratory and microbiologic findings, treatment, and outcome of the patients. RESULTS: Group I had higher prevalence rates of male patients and chronic alcoholics, but lower prevalence rates of biliary disease, hypertension, and malignancy. In laboratory findings, group II had higher incidence of thrombocytopenia, elevated blood urea nitrogen and creatinine. There were no differences in symptoms and microbiologic findings in blood and pus among the three groups. Liver abscesses were more common in right liver in Group I. The lengths of stay and the treatment modalities were similar in three groups. CONCLUSIONS: Although there were differences in sex ratio, etiology, underlying disease among the different age groups, they did not cause difference in treatment and clinical outcome of pyogenic liver abscess. Thus, we recommend active treatments in patients of all age.

BACKGROUND/AIMS: The aim of this study was to evaluate the characteristics of cryptogenic and biliary pyogenic liver abscess by comparing the clinical aspects between the two groups. METHODS: Of 119 patients treated for pyogenic liver abscess from 2000 to 2004, 82 subjects with cryptogenic liver abscess and 21 with biliary abscess were analysed retrospectively. RESULTS: There were no significant differences between the two groups regarding clinical symptoms. The characteristics of abscess were similar except the size of abscess. The size of abscess less than 5 cm in diameter was more common in billiary group than in cryptogenic group (p=0.004). Compare to cryptogenic group, biliary group had more positive culture test from abscess (100% vs. 69%, p=0.006). Especially, E. coli isolated from abscess culture (28% vs. 7%, p=0.014) and blood culcure (23% vs. 4%, p=0.035) were more common in biliary group than in cryptogenic group. There was no difference in mortality between the two groups (biliary vs. cryptogenic: 4.8% vs. 0%, p=0.204). However, the rate of clinical improvement was higher in cryptogenic group than in biliary group (92.7% vs. 66.7%, p=0.001). CONCLUSIONS: Biliary liver abscess had similar clinical characteristics to cryptogenic origin. Biliary liver abscess had smaller abscess size and more positive abscess culture rates than cryptogenic abscess. Improvement rate without complication and recurrence was higher in cryptogenic group than biliary group.
