Abstract
Paeniclostridium sordellii, an anaerobic bacterium, causes hepatic infections in alcoholics and post-surgery (liver transplantation). While liver and brain abscesses are rare, drainage procedures and targeted antibiotic therapy assisted by early microbiological diagnosis have reduced mortality rates. We report a rare case of pyogenic liver abscess caused by Paeniclostridium sordellii in India, the early diagnosis of which has led to life saving outcome for the patient. Hence, the microbiological diagnosis and comprehensive medical-surgical treatment are vital for preventing mortality in Paeniclostridium sordellii infections.

Sohrabi M, Pirbonyeh N, Alizade Naini M, Rasekhi A, Ayoub A, Hashemizadeh Z, Shahcheraghi F. A challenging case of carbapenem resistant Klebsiella pneumoniae-related pyogenic liver abscess with capsular polysaccharide hyperproduction: a case report. BMC Infect Dis 2024; 24:433. [PMID: 38654215 PMCID: PMC11040961 DOI: 10.1186/s12879-024-09314-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 04/11/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Carbapenem-resistant Klebsiella pneumoniae (CRKP) infections are a major public health problem, necessitating the administration of polymyxin E (colistin) as a last-line antibiotic. Meanwhile, the mortality rate associated with colistin-resistant K. pneumoniae infections is seriously increasing. On the other hand, importance of administration of carbapenems in promoting colistin resistance in K. pneumoniae is unknown. CASE PRESENTATION We report a case of K. pneumoniae-related pyogenic liver abscess in which susceptible K. pneumoniae transformed into carbapenem- and colistin-resistant K. pneumoniae during treatment with imipenem. The case of pyogenic liver abscess was a 50-year-old man with diabetes and liver transplant who was admitted to Abu Ali Sina Hospital in Shiraz. The K. pneumoniae isolate responsible for community-acquired pyogenic liver abscess was isolated and identified. The K. pneumoniae isolate was sensitive to all tested antibiotics except ampicillin in the antimicrobial susceptibility test and was identified as a non-K1/K2 classical K. pneumoniae (cKp) strain. Multilocus sequence typing (MLST) identified the isolate as sequence type 54 (ST54). Based on the patient's request, he was discharged to continue treatment at another center. After two months, he was readmitted due to fever and progressive constitutional symptoms. During treatment with imipenem, the strain acquired blaOXA-48 and showed resistance to carbapenems and was identified as a multidrug resistant (MDR) strain. The minimum inhibitory concentration (MIC) test for colistin was performed by broth microdilution method and the strain was sensitive to colistin (MIC < 2 µg/mL). Meanwhile, on blood agar, the colonies had a sticky consistency and adhered to the culture medium (sticky mucoviscous colonies). Quantitative real-time PCR and biofilm formation assay revealed that the CRKP strain increased capsule wzi gene expression and produced slime in response to imipenem. Finally, K. pneumoniae-related pyogenic liver abscess with resistance to a wide range of antibiotics, including the last-line antibiotics colistin and tigecycline, led to sepsis and death. CONCLUSIONS Based on this information, can we have a theoretical hypothesis that imipenem is a promoter of resistance to carbapenems and colistin in K. pneumoniae? This needs more attention.

Abstract
OBJECTIVES Pyogenic liver abscess (PLA) is a severe and potentially fatal infectious disease. Klebsiella pneumoniae (K. pneumoniae) is the predominant pathogen responsible for PLA. This study aims to investigate the clinical characteristics and prognostic factors of K. pneumoniae-induced pyogenic liver abscess (KP-PLA), particularly those caused by carbapenem-resistant K. pneumoniae (CRKP). METHODS Analyses were performed on PLA patients from January 2010 to December 2021, to investigate the differences of K. pneumoniae from other etiologically infected PLA patients. Univariate and multivariate logistic regression analyses were used to compare prognostic factors between patients with carbapenem-resistant K. pneumoniae PLA (CRKP-PLA) and patients with carbapenem-sensitive K. pneumoniae PLA. RESULTS Univariate analysis demonstrated a significant association between KP-PLA and factors including diabetes mellitus (P < 0.001), cholecystitis and cholelithiasis (P = 0.032), single abscess (P = 0.016), and abscesses with a diameter over 50 mm (P = 0.004). The CRKP group exhibited a higher prevalence of therapeutic interventions before K. pneumoniae infection, including abdominal surgery, mechanical ventilation, sputum suction, tracheal cannula, routine drainage of the abdominal cavity, and peripherally inserted central venous catheters (P < 0.05). Multivariate logistic regression analysis revealed that admission to the intensive care unit was an independent risk factor associated with CRKP-PLA (odds ratio 36; 95% confidence interval 1.77-731.56; P = 0.020). CONCLUSION The KP-PLA patients were significantly associated with diabetes and were more likely to have single abscesses larger than 50 mm. PLA patients with a history of admission to intensive care unit or invasive therapeutic procedures should be given special consideration if combined with CRKP infection.

Abstract
OBJECTIVE To elucidate the molecular mechanisms governing the effect of Tounongsan decoction (, TNS) on the pyogenic liver abscess. METHODS Based on oral bioavailability and drug-likeness, the main active components of TNS were screened using the Traditional Chinese Medicine Systems Pharmacology platform. The GeneCard and UniProt databases were used to establish a database of pyogenic liver abscess targets. The interactive network map of drug-ingredients-target-disease was constructed using Cytoscape software (Version 3.7.2). A protein-protein interaction network was constructed using the STRING database, and the related protein interaction relationships were analyzed. biological process of gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed for the core targets. Finally, a clinical trial was performed to verify the reliability of the network pharmacology. RESULTS Forty active components of TNS decoction were obtained, and 61 potential targets and 11 proteins were identified. Pathways involved in the treatment of pyogenic liver abscess include the phosphatidylinositide 3-kinases-protein kinase B (PI3K-AKT), advanced glycation end products-receptor for advanced glycation end products (AGE-RAGE), and tumor necrosis factor (TNF) signaling pathways. The results of network pharmacology analysis combined with clinical trials validated that TNS decoction could alleviate the inflammatory response of pyogenic liver abscesses by decreasing interleukin 6 (IL-6) levels. CONCLUSIONS TNS decoction has the characteristics of being multi-system, multi-component, and multi-target. Active ingredients in TNS, such as quercetin, kaempferol, fisetin, and β-sitosterol, have strong potential to be candidate drugs for treating pyogenic liver abscesses. The possible mechanism of TSN decoction includes regulating immune and inflammatory responses and reducing IL-6 production to control inflammatory development.

Abstract
Pyogenic liver abscesses are potentially fatal conditions that require prompt treatment with drainage and appropriate antimicrobial therapy. Fusobacterium necrophorum is a gram-negative rod that is found in the oral cavity, gastrointestinal tract and female genital tract. It is an extremely rare cause of liver abscess, particularly in the absence of risk factors or exposures. We describe an unusual case of a cryptogenic F. necrophorum hepatic abscess without a clear source despite extensive investigation in a young, immunocompetent patient without known risk factors or exposures for such an infection.

Abstract
BACKGROUND Out of the context of haematological patients, Candida sp. is rarely retrieved from pyogenic liver abscesses (PLA). OBJECTIVES Our objective was to assess the risk factors for occurrence, and clinical, microbiological characteristics, management and outcome of Candida pyogenic liver abscesses (C-PLA). PATIENTS/METHODS We retrospectively analysed C-PLA cases and compared them to pyogenic liver abscesses exclusively due to bacteria (B-PLA) included in our monocentric database on liver abscesses. Unfavourable course was defined as the occurrence of a primary treatment failure (PTF), recurrence after an initial cure, or death within 3 months after diagnosis. RESULTS Between 2010 and 2018, 15 C-PLA and 292 B-PLA were included. All C-PLA had a biliary origin and were polymicrobial. All patients with C-PLA had at least one comorbidity at risk for Candida infection and 7 (53.3%) presented with sepsis requiring an admission in intensive care unit. Median duration of antifungal treatment was 42 days [24-55]. In multivariate analysis, compared with B-PLA, a medical history of malignancy (OR 4.16; 95%CI 1.15-18.72) or liver abscess (OR 7.39; 95%CI 2.10-26.62), and sepsis with severity criteria (OR 3.52; 95%CI 1.07-11.90) were independently associated with the occurrence of C-PLA. In multivariate analysis, C-PLA was associated with a higher risk of recurrence (HR 3.08; 95%CI 1.38-11.22). CONCLUSION Candida liver abscesses in non-neutropenic is a rare and severe disease. The high rate of recurrence should lead to discuss a more intensive treatment.

Abstract
We report a case of a woman with diabetes mellitus and choledocholithiasis who had a low fever with chills and severe weakness for 7 days. The patient's abdominal tenderness was positive. Computed tomography and magnetic resonance imaging showed a giant abscess in the liver. The production of extended-spectrum β-lactamases by hypervirulent Klebsiella pneumoniae was found in the purulent fluid of the liver by nanopore-based metagenomic third-generation sequencing combined with an antibiotic susceptibility test. The patient recovered after intravenous antibiotic therapy and percutaneous drainage. Patients with a history of diabetes mellitus and choledocholithiasis should be aware of the possibility of pyogenic liver abscesses caused by hypervirulent Klebsiella pneumoniae. To rapidly control the development of this disease, nanopore-based metagenomic third-generation sequencing plays an important role not only in rapidly identifying pathogens, but also in guiding the use of antibiotics.

Abstract
Background Pyogenic liver abscess (LA) is a significant contributor to morbidity and mortality in developing countries like India. The risk factors predisposing to the LA specifically in children are not known. Studies done in the past largely remain inconclusive and have identified only probable causes. The cause of LA in children with no coexisting illness remains unknown. Methodology This prospective observational study was conducted at a tertiary teaching hospital located in New Delhi, India. All children between 2 months and 12 years of age with sonographically confirmed LA presenting to the hospital were included and managed with appropriate intravenous antibiotics and relevant investigations. Results A total of 52 children were included. The mean age was 6 years and 4 months, and the male: female ratio was 1.4:1. Around 50% of the patients were malnourished. Fever, abdominal pain and loss of appetite were the most common symptoms. Nine patients (17%) were managed conservatively, 13 (25%) needed percutaneous needle aspiration and 30 (57.69%) required drainage using a pigtail catheter. Poor socioeconomic status and anaemia were found to be the most commonly associated risk factors. Selective immunoglobulin A (IgA) deficiency was the most common primary immunodeficiency disorder followed by T-cell defect. On multivariate analysis, it was seen that in those with clinical icterus, gamma-glutamyl transferases >350 IU/m, and those with impending rupture, the time to defervescence was significantly different (P = 0.05). Conclusion Poor socioeconomic status causing malnutrition emerged as a significant risk factor for LA in children. Selective IgA deficiency was the most common immunodeficiency seen in a few children. Adopting a conservative approach like aspiration and percutaneous drainage led to lower mortality and good recovery rates.

Abstract
INTRODUCTION This study determined the therapeutic effect of ulinastatin (UTI) on unliquefied pyogenic liver abscesses complicated by septic shock (UPLA-SS). METHODS This was a randomized controlled trial involving patients with UPLA-SS who underwent treatment at our hospital between March 2018 and March 2022. The patients were randomly divided into control (n = 51) and study groups (n = 48). Both groups received routine treatment, but the study group received UTI (200,000 units q8h for >3 days). Differences in liver function, inflammatory indices, and effectiveness between the two groups were recorded. RESULTS Following treatment, the white blood cell count, and lactate, C-reactive protein, procalcitonin, tumor necrosis factor-α, and interleukin-6 levels were significantly decreased in all patients compared to the admission values (p < .05). The study group had a faster decline with respect to the above indices compared to the control group (p < .05). The study group length of intensive care unit stay, fever duration, and vasoactive drug maintenance time were all significantly shorter than the control group (p < .05). The total bilirubin, alanine aminotransferase, and aspartate aminotransferase levels were significantly lower in the study and control groups after treatment compared to before treatment (p < .05); however, the study group had a faster recovery of liver function than the control group (p < .05). The overall mortality rate was 14.14% (14/99); 10.41% of the study group patients died and 17.65% of the control group patients died, but there was no statistically significant difference between the two groups (p > .05). CONCLUSION UTI combined with conventional treatment significantly controlled the infection symptoms, improved organ function, and shortened the treatment time in patients with UPLA-SS.

Abstract
INTRODUCTION Reports of extraintestinal manifestations of Clostridioides difficile (C difficile) infections are rare. The frequency of these infections comprises approximately 0.17% to 0.6% of all C difficile infections. While they are becoming more frequent worldwide, the precise trend is unclear. CASE PRESENTATION An 83-year-old female patient presented with pleuritic chest pain 2 to 3 months after a needle biopsy of her liver abscess confirmed C difficile. She was found to have extension of the liver abscess into the chest cavity, leading to empyema, and was treated with intravenous antimicrobials. DISCUSSION This is the fifth known reported case of C difficile leading to a pyogenic liver abscess and the first case where the C difficile liver abscess was associated with an empyema. While long-term metronidazole is considered effective for managing extra intestinal C difficile infection, our patient was treated with vancomycin and meropenem. CONCLUSION To determine epidemiology and a proper treatment regimen for extraintestinal C difficile infection, a greater accumulation of cases is necessary.

Abstract
Objectives: Liver abscess can develop as a complication of hepatobiliary disease or other intraabdominal infections, but more recently it is associated with primary and secondary liver malignancies and their treatment. The goal of this study was to analyze the epidemiology, etiology and clinical characteristics of pyogenic liver abscess in Oman. The intention was to obtain the information needed for the adequate liver abscess empirical treatment. Methods: This retrospective study took place in a tertiary hospital. Consecutive patients treated for the liver abscess during the five years period, from January 2013 until the end of 2017, were enrolled. Their demographic and clinical data were used to study the characteristics of pyogenic liver abscess in Oman. Results: Fifty-three patients with pyogenic liver abscess were enrolled in the study. They were predominantly male and younger than 60 years. Klebsiella pneumoniae was the most usual bacteria causing the liver abscess. Clinical presentation was unspecific and the abdominal pain and high fever were the most usual symptoms. Conclusion: The majority of pyogenic liver abscesses are caused by K. pneumoniae so the empirical treatment should be started with antibiotic directed against it. Further studies are needed to establish the local role of anaerobic bacteria in pyogenic liver abscess as well as to monitor the presence of hypervirulent K. pneumoniae in Oman.

Abstract
PURPOSE To report a case with unique changes in the retinal nerve fiber layer observed on optical coherence tomography in a 22-year-old patient on chronic linezolid therapy for recurrent pyogenic liver abscesses with underlying chronic granulomatous disease. METHODS History and clinical examination, laboratory evaluation, fluorescein angiography, and optical coherence tomography. RESULTS The patient presented with best-corrected visual acuity of 20/200 in the right eye and 20/125 in the left eye. He had moderate optic disk edema and superotemporal field defects bilaterally. Swept-source optical coherence tomography revealed the presence of retinal nerve fiber layer microcystic spaces. Laboratory tests showed no positive findings except for an elevated lactic acid level. Linezolid-induced optic neuropathy was suspected, and the drug was discontinued. Six weeks after termination of oral linezolid therapy, the optic disk edema and the microcystic spaces in the retinal nerve fiber layer resolved, and the best-corrected visual acuity improved to 20/50 in the right and 20/40 in the left eye, respectively. CONCLUSION Linezolid is a widely used antibiotic with broad-spectrum action. However, chronic use can lead to mitochondrial toxicity that may have protean manifestations. Ocular examination, particularly of the optic nerve and nerve fiber layer using multimodal imaging, is critical in diagnosing such toxicity.

Abstract
Fusobacterium nucleatum is a periodontal commensal and pathogen. In rare cases, these anaerobic gram-negative bacilli have been reported to cause pyogenic liver abscesses (PLAs). We describe a patient who developed a periodontal abscess during the COVID-19 pandemic and was unable to access the restricted General Dental Services at this time. She subsequently developed a F. nucleatum bacteraemia and liver abscess. The non-specific signs and symptoms experienced meant the patient self-isolated due to suspected COVID-19 infection and presentation to hospital was delayed. We also include the results of a literature search of other cases of PLAs attributed to F. nucleatum PLAs often develop insidiously. They require percutaneous drainage and prolonged antimicrobial therapy. Clinicians should be aware of this rare complication of a dentoalveolar infection in a patient who is systemically unwell.

Abstract
Background: Gas-forming pyogenic liver abscess (GFPLA) occurs in 7%-24% of all PLAs and has been associated traditionally with high mortality rates. Studies have suggested that the use of a proactive approach of prompt resuscitation, parenteral antibiotic agents, percutaneous drainage, and a dedicated multi-disciplinary team may improve clinical outcomes. Hence, we aim to investigate whether the clinical outcomes of PLA are determined by gas formation. Methods: This is a retrospective study of patients with PLA from 2007 to 2011. A 1:2 propensity score matching (PSM) analysis was performed using age, co-morbid diabetes mellitus, presence of septic shock, hemoglobin levels, international normalized ratio, creatinine, total bilirubin, positive blood culture and pus culture, and the size of abscess. Baseline demographics, clinical profile, and peri-operative data were compared. Results: There were 213 patients who had PLA: 41 (19.2%) patients had GFPLA and 172 (80.8%) patients had non-GFPLA. The PSM analysis resulted in a total of 108 patients (36 GFPLA and 72 non-GFPLA). Median duration of parenteral antibiotic agents was significantly lower in the GFPLA group (9.5 d vs. 14 d, p = 0.044), but median total duration of antibiotic use was comparable (GFPLA 39 d vs. non-GFPLA 37 d, p = 0.634). Median length of stay (days) did not differ significantly between GFPLA and non-GFPLA (14 vs. 15, p = 0.299). There were no statistically significant differences between GFLPA and non-GFLPA in the need for percutaneous drainage (26/36 (72.2%) vs. 47/72 (65.3%), respectively, p = 0.467) and in-hospital all-cause death (4/36 (11.1%) vs. 7 (9.7%), p = 0.822) Conclusions: Outcomes of GFPLA are comparable to those of non-GFPLA in the era of multi-modal care.

Abstract
PURPOSE To identify the predictors for recovery of pyogenic liver abscess (PLA) patients treated with percutaneous catheter drainage (PCD) and antibiotics, and then develop an effective nomogram to predict the recovery time. MATERIALS AND METHODS The retrospective study included consecutive PLA patients treated with PCD and antibiotics. We defined the overall recovery time (ORT) as the time from the PCD procedure to the time of clinical success or failure. Based on the ORT, its predictors were identified with univariate and multivariate analyses. Then, a nomogram was developed to predict the ORT, and was internally validated by using Harrell's c statistic. RESULTS A total of 116 patients and 142 PCD procedures with a median ORT of 15.0±10.6 days were included. Gas-formation (GF; HR: 0.486 [95% CI 0.312-0.757]; P = 0.001), diabetes mellitus (DM; HR: 0.455 [95% CI 0.303-0.682]; P<0.001), and preinterventional septic shock (PSS; HR: 0.276 [95% CI 0.158-0.483]; P < 0.001) were identified as predictors for the ORT of combination therapy after univariate and multivariate analyses, which indicated a significantly longer ORT than those patients without. The prognostic analyses demonstrated that the more predictors (GF, DM, and PSS) a patient exhibited, the longer ORT for the combination therapy. A nomogram was developed to predict the ORT and revealed high accuracy, with Harrell's c statistic of 0.73. CONCLUSION GF, DM, and PSS were predictors for the recovery of PLA patients treated with PCD and antibiotics. The nomogram was effective in predicting the ORT of combination therapy.

Abstract
Endogenous K. pneumoniae endophthalmitis (EKE) has a higher incidence among East Asians, and the most common infectious source of EKE is pyogenic liver abscess (PLA). We investigate the risk factors for poor visual outcomes in patients with PLA-related EKE. The retrospective medical records of 104 patients (120 eyes) diagnosed with PLA-related EKE between 1996 and 2015. In univariate logistic regression analysis, the risk factors for poor visual outcomes were initial visual acuity (VA) worse than counting fingers (CF) (p < 0.001), eye pain (p = 0.013), hypopyon (p = 0.003), ocular hypertension (p = 0.003), positive intraocular fluids cultures (p < 0.001), subretinal abscess (p = 0.025), unilateral involvement (p = 0.017), delayed ophthalmologic visit (p = 0.022), initially presented with ocular symptoms ahead of systemic symptoms (p < 0.001), and corneal edema (p < 0.001). Intravitreal dexamethasone reduced the requirement of enucleation or evisceration (p = 0.01). The multivariate logistic regression revealed that poor initial VA worse than CF (p = 0.004) and initially presented with ocular symptoms ahead of systemic symptoms (p = 0.007) were the significant independent factors for poor visual outcomes. Early diagnosis and prompt treatment may salvage useful vision in some eyes.

Abstract
This study aimed to analyze the clinical manifestations of patients with pyogenic liver abscess and characteristics of pathogenic that caused their infections, in order to provide guidance for the identification of the pathogens that cause liver abscess and selection of antibiotics for treatment of this disease.In the present study, the clinical characteristics, laboratory results, as well as the species and drug resistance of pathogens in patients with bacterial liver abscesses admitted to our hospital from January 2013 to December 2015 were retrospectively analyzed. The patients were treated by ultrasound or CT-guided percutaneous portal vein catheterization and drainage combined with intravenous infusion of antibiotics (the third-generation cephalosporins, the coformulation of carbapenem and dehydropeptidase-I inhibitors, or the coformulation of tazobactam and piperacillin).A total of 178 patients were diagnosed with liver abscess by B ultrasound or CT. The abscesses mostly occurred in elderly male patients and patients with diabetes mellitus. The major clinical and hematological features were fever (163/178, 91.2%), single focal abscess (146/178, 82.0%), elevated white blood cell count, and percentage of neutrophils (136/178, 76.4%). A total of 102 nonrepetitive strains of bacteria were isolated, including Klebsiella pneumoniae (82 strains, 80.3%), Escherichia coli (8 strains), Pseudomonas aeruginosa (2 strains), Acinetobacter baumannii (1 strain), and Gram-positive cocci (9 strains). Susceptibility to antimicrobial drugs was determined by analyzing the minimum inhibitory concentration, and among the 8 cultured E coli strains, 5 strains that could produce extended-spectrum β-lactamase (ESBLs) were among the most commonly seen nosocomial infections. In the present study, bacterial liver abscesses were mostly community-acquired, and K pneumoniae was highly susceptive to the commonly used antibiotics. Five patients had poor outcomes due to infectious shock or the accompanying liver cancer. In other patients, after treatment, the body temperature and the inflammatory indices, such as the total white blood cell count and C-reactive protein, returned to normal levels, and the area of abscess decreased.Most of the bacterial liver abscesses were caused by K pneumoniae, in which only a few strains exhibited resistance to the commonly used antibiotics. The use of ultrasound- or CT-guided percutaneous drainage combined with antibiotics was an appropriate way to treat the liver abscesses of these patients.

Abstract
Pyogenic liver abscess (PLA) is a potentially life-threatening disease affecting many parts of the world, especially Asia. In this study, we explored the clinical and microbiological characteristics of PLA in Chinese patients.A 5-year (2010-2014) retrospective review of medical records on all PLA patients who were admitted to a tertiary teaching hospital was performed.Among 217 PLA cases who were confirmed cultural positive, Klebsiella pneumonia (K pneumonia) was the most common pathogen (n = 165, 76.0%), followed by Escherichia coli (n = 21, 9.7%). Notably, there is a higher incidence of diabetes mellitus in patients with K pneumoniae-induced PLA (KP-PLA) than that with non-K pneumoniae-induced PLA (non-KP-PLA)(43.0% vs 21.2%, P = .005). However, it was less prevalent for concomitant hepatobiliary disease (20.0% vs 34.6%, P = .039) and history of intraabdominal trauma or surgery (13.3% vs 38.5%, P < .001) in patients with KP-PLA. Although K pneumoniae are sensitive to most common antibiotics (antibiotic resistance rates below 10%), some strains (1.2%) developed resistant to carbapenem. These results confirmed K pneumoniae as the predominant pathogen of PLA in the area in which the study was conducted. More attention should be directed toward monitoring the emergence of carbapenem-resistant K pneumoniae.KP-PLA is frequently diagnosed in patients with metabolic diseases accompanied by serious consequences, and it is therefore prudent to see that they receive sensitivity-directed antibiotic therapy.

Abstract
This retrospective cohort study investigated the feasibility of radiofrequency (RF) ablation as an alternative to surgical intervention in patients with huge multiloculated pyogenic liver abscesses (PLAs).From August 2010 to April 2016, 83 patients with PLA were admitted to Beijing Chao-Yang Hospital, China. Four of these patients had huge multiloculated PLAs and underwent RF ablation plus antibiotics. The inclusion criteria for RF ablation were as follows: multiloculated PLA confirmed by computed tomography (CT) or magnetic resonance imaging (MRI), widest diameter of the PLA ≥5 cm, failure to respond to or not suitable to treatment with percutaneous drainage (PD), and patient refusal of surgery. The safety and effectiveness of RF ablation were initially assessed. All patients were commenced on antibiotics on admission to our hospital. CT-guided percutaneous catheter drainage was attempted in one patient but was unsuccessful. The main organism isolated from cultures of these patients' blood or abscess samples was Klebsiella pneumoniae (3/4). RF ablation was performed as soon as eligibility according to the above criteria was established.RF ablation was technically successful in all 4 study patients, all PLAs being completely eradicated. The median duration of fever after RF ablation was 4.5 days. No abscesses recurred; thus, this strategy for managing PLA was 100% successful (4/4). No procedure-related deaths or major complications occurred. One patient had an asymptomatic right pleural effusion that resolved with conservative treatment including albumin infusion and diuretics.Our preliminary data indicate that RF ablation is a safe, feasible, and effective treatment for huge multiloculated PLAs. It should be considered as an alternative treatment for patients who fail to respond to or not suitable for PD plus antibiotics and refuse surgical intervention.

Abstract
BACKGROUND Etiologic organism is not frequently isolated despite multiple blood and fluid cultures during management of pyogenic liver abscess (PLA). Such culture negative pyogenic liver abscess (CNPLA) is routinely managed by antibiotics targeted to Klebsiella pneumoniae. In this study, we evaluated the outcomes of such clinical practice. METHODS All the patients with CNPLA and Klebsiella pneumoniae PLA (KPPLA) admitted from January 2003 to December 2011 were included in the study. A retrospective review of medical records was performed and demographic, clinical and outcome data were collected. RESULTS A total of 528 patients were treated as CNPLA or KPPLA over the study period. CNPLA presented more commonly with abdominal pain (P=0.024). KPPLA was more common in older age (P=0.029) and was associated with thrombocytopenia (P=0.001), elevated creatinine (P=0.002), bilirubin (P=0.001), alanine aminotransferase (P=0.006) and C-reactive protein level (P=0.036). CNPLA patients tend to have anemia (P=0.015) and smaller abscess (P=0.008). There was no difference in hospital stay (15.7 vs 16.8 days) or mortality (14.0% vs 11.0%). No patients required surgical drainage after initiation of medical therapy. CONCLUSION Despite demographic and clinical differences between CNPLA and KPPLA, overall outcomes are not different.

Abstract
Among the etiologies of pyogenic liver abscess (PLA), bacterial spread from the biliary tract or portal flow is the major cause, while the onset of PLA due to arterial bacterial transmission is rare. We herein report two cases of PLA thought to be caused by arterial transmission from dental disease. In both cases, there was benign biliary stricture as a result of alcoholic chronic pancreatitis, although normal oral flora was detected as the causative bacteria and oral hygiene was poor in both patients. We presumed that the origin of PLA was dental disease and successfully treated the patients with percutaneous drainage, antibiotics and dental procedures.

Abstract
Pyogenic liver abscess is a rare complication of diabetes, usually seen in adults greater than 50 years of age who have had diabetes for many years. We describe an 18-year-old male with type 2 diabetes found to have a pyogenic liver abscess caused by Klebsiella pneumoniae, and show accompanying images from his evaluation for fever of unknown origin (FUO). We conclude that in a child or adolescent with FUO and diabetes, occult pyogenic liver abscess must be considered.
