Objective To investigate the iron regulated locus in Klebsiella pneumoniae isolates from blood culture of liver abscess patients in Sichuan Provincial People’s Hospital. Methods From January to December of 2015, a total of 10 isolates of Klebsiella pneumoniae were collected from blood culture of liver abscess patients from Sichuan Provincial People’s Hospital. The genomic DNA was extracted to identify the genes of iroB, iroC, and iroD by PCR, and data was further analyzed by Graphpad Prism 5 software. Results Among the 10 Klebsiella pneumoniae clinical strains, 9 strains were iroB positive strains, 9 strains were iroC positive strains, and 10 strains were iroD positive strains, 9 strains were iroB/C/D triple positive. Conclusion The current study suggests that the frequency of triple positive of iroB/C/D in Klebsiella pneumoniae is high in isolates from liver abscess patients, the triple positive of iroB/C/D may contribute to liver abscess.
Objective To explore the clinical manifestations, computed tomography features, management and prognosis of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism. Methods The clinical data of patients with Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism admitted to Dongnan Hospital of Xiamen University from January 2012 to January 2017 were retrospectively analyzed. Results There were 8 patients who had Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism. Fever occurred in all patients, respiratory symptoms were noted in 5 patients, abdominal pain occurred in 2 patients, endophthalmitis coexisted in 1 patient, and diabetes mellitus coexisted in 7 patients, with no chest pain or hemoptysis. In biochemical indexes, procalcitonin increased most obviously. Microbiological studies revealed Klebsiella pneumoniae in 8 patients. Chest CT showed peripheral nodules with or without cavities, peripheral wedge-shaped opacities, a feeding vessel sign, pleural effusion, and infiltrative shadow. One patient finally deteriorated to acute respiratory failure, and died due to acute respiratory distress syndrome and/or septic shock. There was one case of spontaneous discharge. A total of 6 patients were improved and cured. Conclusions The clinical manifestation of Klebsiella pneumoniae liver abscess complicated with septic pulmonary embolism is unspecific and misdiagnosis rate is relatively high. The major characteristics of chest CT scan include peripheral nodules with or without cavities, peripheral wedge-shaped opacities and a feeding vessel sign. Diagnosis and differential diagnosis can be made based on these features combined with clinical data and primary disease (liver abscess).
Objective To determine the effectiveness of percutaneous catheter drainage (PCD) and to compare PCD with percutaneous needle aspiration (PNA) in the management of bacterial liver abscess. Methods The medical records of 206 patients with bacterial liver abscess admitted to this hospital between January 1989 and December 2009 were analyzed retrospectively. The outcomes of 96 patients receiving percutaneous treatment including PCD (PCD group, n=56) and PNA (PNA group, n=40) were compared, including the length of hospital stay, rates of procedure-related complications, treatment success, and death. Results There was no statistical difference in patients’ demographics or abscess characteristics between two groups (Pgt;0.05). The morbidity, mortality, and length of hospital stay in the PCD group and the PNA group were 1.79% vs 2.50%， 1.79% vs 2.50%， and (19.2±13.1) d vs (20.2±12.9) d, respectively, and the P values were 1.000, 1.000, and 0.887, respectively. There was statistically significant difference in successful rate between two groups （96.43% vs 75.00%， P=0.002）, but all simple abscesses with diameter of 5 cm or less were successfully managed in both PNA group and PCD group （13/13 vs 16/17， P=1.000）. Conclusions PCD is more effective than PNA in the management of bacterial liver abscess. PNA can be used as a valid alternative for simple abscesses with 5 cm in diameter or smaller.

Rupture is one of main complications of liver abscess. Seventy-seven patients with rupture of liver abscess are reviewed. Liver abscess may freely rupture into adjacent structures or organs or serous cavities and cause vatious complications. The causative factors of rupture of liver abscess in this series were late medical consultation in the course of the disease, delayed treatment due to misdiagnosis, and improper treatment. Measures that prevent rupture of liver abscess include raising clinical awareness of early diagnosis and timely effective drainage. The authors consider that transperitoneal surgical drainage is the best approach. Most patients with rupture of liver abscess should be treated by surgical drainage togather with transomental or transumbilital veno-catheterization for antibiotic infusion. Patients with rupture of liver abscess usually present a poor prognosis and a high mortality rate. The mortality in this group was 35.1%(27/77), which is closely related to the complications of the rupture of liver abscess.
Objective To analyze the treatment and effect of bacterial liver abscess over the past two decades in one single center. Methods The total 198 patients with bacterial liver abscess during the last twenty years were studied retrospectively. They were divided into three groups according time: 1989-1995 group, 1996-2002 group and 2003-2008 group. Gender and age of patient, location, number and size of abscesses, treatment, hospital days, morbidity of complications and mortality among the groups were compared. Results There were 54, 69, 75 cases in 1989-1995, 1996-2002 and 2003-2008 group respectively. No significant differences were found in gender and age of patient, location, number and size of abscess among three groups （Pgt;0.05）. In 1989-1995 group, 35 cases (64.8%) were treated with laparotomy, 8 cases (14.8%) with laparoscope, and 11 cases (20.4%) with percutaneous treatment (needle aspiration or catheter drainage). In 1996-2002 group, 15 cases (21.8%) were treated with laparotomy, 21 cases (30.4%) with laparoscope, 31 cases (44.9%) with percutaneous treatment (needle aspiration or catheter drainage), and 2 cases (2.9%) were treated with antibiotherapy. In 2003-2008 group, 5 cases (6.7%) were treated with laparotomy, 13 cases (17.3%) with laparoscope, 54 cases (72.0%) with percutaneous treatment (needle aspiration or catheter drainage), and 3 cases (4.0%) were treated with antibiotherapy. The constituent ratio of treatment was significantly different among three groups (P＜0.05). The hospital days was (18.5±12.2) d, (16.4±12.8) d and (20.1±14.6) d, the morbidity of complications was 9.3% (5/54), 4.3%(3/69) and 4.0%(3/75), the mortality was 3.7%(2/54), 1.4%(1/69) and 1.3% (1/75) respectively, but there were no significant differences of three indexes among three groups. Conclusion With the development of surgical techniques, effective antibiotic therapy and percutaneous treatment (needle aspiration or catheter drainage) have been the main therapeutic methods, and laparoscopy and laparotomy are necessary supplement.
Objective To formulate an evidence-based treatment plan for a patient with suspected pyogenic liver abscess. Methods Based on the clinical questions raised by a patient with suspected pyogenic liver abscess, we searched The Cochrane Library (Issue 4, 2007), MEDLINE (1996 to January 2008), ACP Journal Club (1991 to January 2008), and Chinese Journal Full-text Database (1994 to January 2008) for systematic reviews, randomized controlled trials (RCTs) and case-control studies. The quality of the included studies was assessed. Results We did not find any systematic reviews or large-scale RCTs involving a comparison between laparoscopic drainage and surgical drainage in the treatment of pyogenic liver abscess. Four clinical retrospective studies closely related to our questions were found and assessed. These studies concluded that laparoscopic drainage for liver abscesses was a safe alternative for patients requiring surgical drainage. Based on the current evidence, as well as our clinical expertise and the patient’s values, laparoscopic drainage was not used for this patient and surgical drainage was applied. The patient was recovered and discharged. Conclusion Current evidence showed that laparoscopic drainage might be effective and safe for liver abscesses but high-quality large-scale randomized controlled trials are still required.
ObjectiveTo compare the clinical features of bacterial liver abscess (BLA) with or without diabetes and provide reference for clinical diagnosis and treatment.MethodsThe clinical data of 312 patients with BLA admitted to Huaian First People’s Hospital of Nanjing Medical University from January 2016 to January 2020 were collected. The differences in the clinical symptoms and signs, results of laboratory, imaging, etiological tests, treatment methods, and outcomes of the patients between with and without diabetes were compared.ResultsA total of 312 patients with BLA were collected, 128 BLA patients with diabetes and 184 BLA patients without diabetes. ① There were no significant differences in gender and age between patients with and without diabetes, but the boby mass index of BLA patients with diabetes was higher than that of the patients without diabetes [(25.54±4.99) kg/m2 versus (23.75±3.92) kg/m2, t=3.546, P<0.001]. ② In terms of etiology, the main cause of BLA was the biliary tract infection [37.18% (116/312)]. The incidence of cryptogenic infections in the BLA patients with diabetes was significantly higher than that of the BLA patients without diabetes [39.06% versus 26.63%, χ2=5.386, P=0.020]. ③ In terms of clinical manifestations, the fever was the main symptom of BLA [97.76% (305/312)]. The incidences of abdominal pain and percussion pain in the liver area of BLA patients with diabetes were significantly lower than those in the BLA patients without diabetes [32.03% versus 51.63%, χ2=11.793, P=0.001; 15.63% versus 30.98%, χ2=9.572, P=0.002]. ④ In terms of laboratory tests, compared with the patients without diabetes, the albumin level was lower [(30.88±5.25) g/L versus (33.67±4.33) g/L, t=–5.139, P<0.001], the procalcitonin level and neutral cell ratio were higher [(44.22±39.56) μg/L versus (36.03±22.73) μg/L, t=2.312, P=0.021; (86.68±7.05)% versus (80.73±8.12)%, t=6.710, P<0.001] in the patients with diabetes. ⑤ In terms of imaging findings, the BLA was mainly single abscesses [77.56% (242/312)] and mainly in the right lobe [66.34% (207/312)]. ⑥ In terms of microbiological examination, the bacterial positive detection rate of all patients was 71.15% (222/312). The main pathogen was Klebsiella pneumoniae [71.62% (159/222)]. The Klebsiella pneumoniae infection rate in the BLA patients with diabetes was higher than that in the BLA patients without diabetes [79.30% versus 66.67%, χ2=4.161, P=0.041]. ⑦ The septic shock occurred in 20 (6.41%) patients with BLA. After treatment of all patients, 4 cases of BLA with diabetes and 2 cases of BLA without diabetes died. The patients who died all came from septic shock.ConclusionsClinical manifestations of BLA patients with diabetes are atypical and main infection is Klebsiella pneumoniae. When BLA combined with septic shock, individual treatment strategy should be chosen basing on actual situation of patient.
