Metastatic chorioretinal abscess: an unusual complication of pyogenic liver abscess

Endogenous endophthalmitis associated with pyogenic liver abscess caused by Klebsiella pneumoniae: A case report

It is about an exceptional case of endogenous endophthalmitis secondary to a liver abscess due to Klebsiella pneumonia. The patient was a 50-year-old female, who was admitted for fever and right upper quadrant abdominal pain. Abdominal computed tomography showed an abscess measured 8 cm and located in segment 7 of the liver. It was treated by antibiotics and percutaneous transhepatic drainage. Pus sample was positive for Klebsiella pneumoniae. On day 3 after admission, patient complained of a red left eye with decreased vision. The diagnosis of endogenous endophthalmitis was strongly suspected. An Early treatment was initiated with a good evolution. The syndrome Endophthalmitis-hepatic abscess" is an exceptional syndrome rarely reported in the literature. It must evoked in case of hepatic abscess caused by klebsiella pneumonia.

A rare case of caudate lobe liver abscess

Indian subcontinent has high incidence of both amoebic and pyogenic liver abscess. Currently most of the liver abscesses are managed with interventional radiology based percutaneous drainage (either ultrasound or CT guided). Caudate lobe liver abscess is both a rare and at a peculiar location for such intervention as well as carries a high risk of rupture posing a great challenge for the surgeon in planning the appropriate management. In view of viscinity to vascular structures and viscera near liver hilum and difficult approach by laparoscopic technique, open surgical drainage seems to be a feasible option.

A population-based study of pyogenic liver abscess in Korea: Incidence, mortality and temporal trends during 2007-2017.

Although the epidemiology of pyogenic liver abscess (PLA) continues to change, only a few population-based studies have been conducted in Korea. This study investigated the epidemiology and clinical outcomes of PLA patients during a period of 10years. We analysed the Health Insurance Review and Assessment Service data between 2007 and 2017. The data included annual incidence rates, demographic data, underlying diseases, complications and mortality of PLA patients. The annual incidence of PLA for all age groups was 10.9 per 100000 population. The incidence was gradually increased from 5.7 per 100000 in 2007 to 14.4 per 100000 in 2017. In patients with liver abscess, the prevalence of diabetes and malignancy were 37.24% and 26.5% respectively. Metastatic infection was reported in 1.74% of the patients, and endophthalmitis was most common. The mean in-hospital mortality was 9.6%, and there was no significant difference in mortality by year during the observation period. Mortality increased with age and was greatly affected by the underlying diseases, especially cancer. Based on the multivariate analysis results, the mortality of PLA patients was associated with older age, female sex, diabetes, malignancy and chronic kidney disease. The PLA incidence is rapidly increasing in Korea, especially in people with comorbidities. In addition, the causes and risk factors of PLA infections are changing and thus further research on epidemiology, different diagnosis and management approaches is required.

Een geriatrische patiënte met een perirectaal abces, pyleflebitis en multipele pyogene leverabcessen: een gevalsbespreking

A geriatric patient with a perirectal abscess, pylephlebitis and multiple pyogenic liver abscesses: a case-report. In this case study, an 86-year-old patient is presented with fever, anorexia and drowsiness, a very high C-reactive protein (CRP) level and elevated liver enzymes. Given the frailty of the patient, a non-invasive diagnostic approach was chosen. Initially, a pancreatic carcinoma with liver metastases was suspected, but the presence of positive blood cultures raised doubts about the initially suggested diagnosis. Ultimately, a perirectal abscess with Streptococcus intermedius bacteremia, pylephlebitis and multiple liver and pancreatic abscesses were diagnosed. After a course of 9 weeks of antibiotics, the patient's condition improved. The vague complaints in this geriatric patient and the lack of invasive diagnostics pose a challenge for the clinician in recognizing this disease.

Ruptured liver abscess mimicking perforated viscus

Background: Liver abscesses are common in the Emergency Department. A cross-sectional study conducted in Qatar showed pyogenic liver abscesses were more common than amebic abscesses. Spontaneous rupture of pyogenic liver abscess is a rare entity with serious complications. A rupture resulting in peritonitis requires urgent surgical intervention whereas localized abscesses are managed with surgical or image-guided percutaneous drainage in addition to appropriate antibiotics. We report a case of spontaneous rupture of liver abscess presented to our Emergency Department that mimicked perforated hollow viscus. Methods/Case presentation: A 58-year-old male patient presented with fever, generalized weakness, anorexia, and abdominal discomfort for 2 weeks. The patient had a history of Type 2 diabetes mellitus and taking oral hypoglycemics. His initial vital signs revealed a temperature of 38.2°C, heart rate of 104 beats per minute, blood pressure of 150/74 mmHg, respiratory rate of 26 breaths per minute, oxygen saturation of 96% on room air. He appeared sick and dehydrated. Pertinent findings on abdominal examination were epigastric and right upper quadrant tenderness. The laboratory report showed leucocytosis and elevated transaminase. A chest X-ray was ordered and revealed air under the diaphragm . Point of care ultrasound showed a right liver lobe hypoechoic lesion with internal echoes and surrounding free fluid. A computed tomography of the abdomen showed a large hepatic lesion (11.5 x 8.5 x 9 cm), subcapsular in location, containing gas with dependent fluid, suggesting a gas-forming hepatic abscess, with the possibility of rupture and pneumoperitoneum. Results/Findings/Recommendations: The patient was admitted and underwent ultrasound guided drainage of the abscess. His blood and pus culture showed Klebsiella pneumonia and he received Ceftriaxone and Metronidazole intravenously (IV) for 14 days. He was discharged after 15 days with a favorable outcome. Conclusion: To the best of our knowledge, spontaneous liver abscess rupture resulting in pneumoperitoneum is rare. Chest X-ray findings may mimic perforated hollow viscus.

A Case Report: Ruptured of Pyogenic Liver Abscess

Background: Most causative of liver abscess, in about 90% of all cases are pyogenic abscess. One of the rare and dangerous complications of pyogenic liver abscess (PLA) that requires urgent management, even with nonspecific signs and symptoms, is abscess rupture. Case Presentation: A 27-years-old male patient with continuous right upper abdominal pain since a week after the patient fell down the stairs and hit the right side of his stomach against the stairs. Abdominal ultrasound revealed heteroechoic lesion with ill borders, irregular margin, and internal moving echo (+) in the right lobe of the liver, which on color doppler examination showed minimal perilesional vascularization. The patient underwent abdominal computed tomography (CT) scan with contrast four days later with showed rim enhancing semisolid lesion (23-33 HU) with air density (-925 HU) within it in, in the segments V to VIII of the right lobe of the liver partially ruptured in the periphery of segments VI-VII of the liver lobe with pneumoperitoneum and ascites. A week later a laparotomy was performed and the culture of the pus specimen revealed a growth of Escherichia coli. Conclusion: Based on clinical symptoms and imaging, PLA is not without any challenges in diagnosis. The key to avoid misdiagnosis of ruptured PLA are meticulous examination of the clinical and imaging also vigilant monitoring.

Epidemiology of pyogenic liver abscesses in Germany: Analysis of incidence, risk factors and mortality rate based on routine data from statutory health insurance.

BackgroundPyogenic liver abscesses (PLAs) represent potentially life‐threatening abdominal conditions that require immediate diagnosis and therapy. European and American incidence figures vary between one and 15 per 100,000 per year. Structured epidemiological data for European countries are not available.ObjectiveTo systematically characterize the epidemiology and clinical outcome of PLA in Germany.MethodsIn representative statutory health insurance data from four million people in 2013–2019, the prevalence and incidence with clinical coding of International Statistical Classification of Diseases and Related Health Problems (ICD)‐10 code K75.0 were selected (n = 1118). Furthermore, demographics, relevant comorbidities, hospitalizations, mortality and complications were determined within one year.ResultsThe incidence of PLA was approximately seven per 100,000. The average age at diagnosis was 66 years; 65% were male. Of these, biliary disease was documented in over 60% and infectious intestinal diseases were found in 21% within the same or previous calendar year. PLA patients had high comorbidity indices. Liver transplant status, malignancies of the liver and biliary system, liver cirrhosis and pancreatitis were strongly associated. Intensive care was documented in 27% of PLA cases. Nine percent died within 12 months, most with an underlying malignant disease.ConclusionPyogenic liver abscess is a rare disease with high morbidity. Predisposing and risk factors include intestinal and biliary diseases as well as hepatic malignancies. Further research should focus on PLA therapy within prospective surveys and controlled clinical trials.

Anterior abdominal wall abscess secondary to spontaneous rupture of liver abscess in a resource-limited, rural, surgical setting: A case report

Liver abscess continues to be a major surgical burden in low-and mid-low-income countries like India. Spontaneous rupture into the anterior abdominal wall is an uncommon presentation of pyogenic liver abscess. A 53-year-old diabetic female presented with acute pain in the right, upper quadrant of the abdomen. On examination, she had an anterior abdominal wall abscess with tender hepatomegaly. On further evaluation with ultrasonography and plain computed tomography, a diagnosis of liver abscess in the right lobe with rupture into the anterior abdominal wall was made. She was treated successfully in a tribal secondary care hospital with an ultrasound-guided aspiration followed by surgical drainage under local anesthesia. This case report highlights that a considerable number of patients with liver abscess and its complications can be appropriately managed in resource-limited, rural, surgical centers.

Clinical features and etiological analysis for 157 cases of pyogenic liver abscess.

To analyze the clinical features and the pathogenic constituent of patients with pyogenic liver abscess (PLA), and to find the risk factors of the multidrug resistance (MDR) pyogenic liver abscess (MDR-PLA) for effective therapy in the PLA patients. We reviewed the PLA patients with antibiotics susceptibility test, who admitted to Xiangya Hospital of Central South University from Jan. 2010 to Dec. 2019. A total of 157 cases were divided into 2 groups: an MDR-PLA group (n=52) and a non-MDR-PLA group (n=107). The clinical data such as age, symptoms, laboratory and imaging data, and etiological test especially drug sensitivity test of the 2 groups were collected. Logistic regression analysis was performed for the risk factors of MDR-PLA. Anorexia (90.38%) and abdominal pain (63.46%) were more common in the MDR-PLA group than those in the non-MDR-PLA group (P<0.05). The proportions of patients with hepatolithiasis (34.62%) and biliary tract operation (38.62%) were higher in the MDR-PLA group than those in the non-MDR-PLA group (P<0.05). Klebsiellapneumoniae (59.94%) was the most common pathogen, which was sensitive to most of the antibiotics, while Escherichia coli and Enterococcus had lower drug sensitivity than Klebsiella lebsiella pneumoniae. The MDR-Enterococcus was 6.5 times of non-MDR-Enterococcus. And the multidrug resistance Klebsiella pneumoniae was 3.4 times of non-MDR-Klebsiella pneumoniae. Logistic regression analysis showed that hepatolithiasis (OR=4.895, 95% CI 1.455 to 16.463, P=0.001) and biliary tract operation (OR=3.860, 95% CI 1.156 to 12.889, P=0.004) were the risk factors for the MDR-PLA patients. The PLA patients with hepatolithiasis and billary tract operation history and the pathogenic bacterium of Escherichia coli and Enterococcus bacteria should be alerted for MDR bacterial infection.

Prospective study to analyze clinico-epidemiological profile of patients presenting with liver abscess at tertiary care centers

Background: Liver abscess is an ancient disease bothering mankind since ages and continues to be a common health problem in India. Both of its subtypes i.e., amoebic and pyogenic, continues to pose serious challenge to the Indian health care system.Aims and objectives: To determine the demographic profile of patients, to assess type of liver abscess prevalent in the region and to assess etiological factors of the disease.Methods: Study was conducted in two tertiary care and referral hospitals in the Indian national capital region and a govt. hospital in Punjab from 01 July 2016 to 31 December 2019 and the patients were followed up till June 2020 with the last recruited patient getting a six month follow up. Diagnosis was confirmed by sonography and examination of aspirate. Positive routine bacteriological culture of the pus and a positive response to routine antibiotics made up for the pyogenic liver abscess category.Results: Liver abscess commonly affects middle aged males of low socioeconomic status. Diabetics and alcohol (both Indian made foreign liquor and the local country liquor) are biggest risk factors. Majority have raised leukocyte counts while Alkaline phosphatase is the most commonly deranged liver function test marker, raised to more than twice of the normal range in most cases. Right lobe involvement, right sided pleural effusion and raised right hemidiaphragm are seen in plain chest X-ray. Fever and pain abdomen are the most common presenting complaints. USG abdomen is an effective diagnostic modality that also serves to guide intervention procedures.Conclusions: Early diagnosis and timely intervention produces best results.International Journal of Human and Health Sciences Vol. 05 No. 04 October’21 Page: 473-477

Clinical Features and Mortality of Endogenous Panophthalmitis in China: A Six-Year Study

ABSTRACT Purpose To report the clinical features, treatment strategy, and mortality of patients with endogenous panophthalmitis (EP). Methods Fifteen patients (16 eyes) diagnosed with EP from December 2012 to December 2018 were investigated with a standard protocol at a tertiary medical center of the largest eye center in Northern China. Mortality was followed up. Results All participants were Han Chinese. The mean age was 58.3, 62.5% were male, and 93.3% were unilaterally involved. The average number of predisposing factors was 3.0. The top two predisposing factors were diabetes mellitus (DM, 93.3%) and pyogenic liver abscess (PLA, 66.7%). All patients initially presented at an ophthalmic emergency due to severe ocular symptoms. All patients were co-managed by relevant specialists and were admitted to medical or surgical wards instead of the eye center unless the systemic condition was well controlled. Only four eyes were eligible for vitrectomy. The mean follow-up duration was 12.5 months. The mortality rate was 0%. The predominant causative organism was Klebsiella pneumoniae (80.0%), and there were no positive fungal cases. Conclusions EP is a rare, life-threatening disease. DM and PLA could predispose its development. The predominant causative organism was Klebsiella pneumoniae. The interdisciplinary cooperation system of the management of EP may reduce the mortality rate.

Liver Abscess: Complications and Treatment.

Liver Abscess Caused by Fusobacterium nucleatum: A Case Report

Introduction: Pyogenic liver abscess (PLA) is a serious infectious disease of the liver. Pyogenic liver abscess caused by Fusobacterium nucleatum is extremely rare. Here we report the first case of liver abscess caused by F. nucleatum in China. Case Presentation: The case was a 34-year-old female patient admitted to the hospital due to high fever. The diagnosis of liver abscess was confirmed by imaging studies and liver puncture. We finally confirmed the pathogen as F. nucleatum by next-generation sequencing (NGS). After the targeted anti-infective treatment, the patient recovered and discharged. Conclusions: As a new microbial detection method, NGS can still help in clinical practice. In addition, to improve the positive rate of anaerobic bacteria culture, we should pay attention to avoid contact with air in the process of specimen collection when the pathogenic bacteria are suspected to be anaerobic bacteria.

Distribution of type VI secretion system (T6SS) in clinical Klebsiella pneumoniae strains from a Chinese hospital and its potential relationship with virulence and drug resistance

ObjectivesThe type VI secretion system (T6SS) in Klebsiella pneumoniae strains isolated from the bloodstream, intestinal, the pyogenic liver abscess has been reported. Here we aimed to characterize T6SS in 248 Klebsiella pneumoniae isolates with all kinds of specimens from a Chinese hospital and to investigate the potential association of T6SS with virulence and drug resistance. MethodsT6SS genes, capsular serotyping genes, drug resistance genes, and virulence genes were identified by polymerase chain reaction (PCR). Antibiotic susceptibilities were examined by the disk diffusion method. To assess biofilm formation of these clinical Klebsiella pneumoniae isolates, 96-well microtiter plate assays were performed. MLST was used to analyze the genotypes of these Klebsiella pneumoniae isolates. ResultsThe frequency of T6SS genes among the clinical Klebsiella pneumoniae isolates was 72.2%. The T6SS-positive isolates displayed higher resistance to piperacillin-tazobactam, ciprofloxacin, levofloxacin, meropenem than the T6SS-negative isolates (P < 0.05). The T6SS-positive isolates formed significantly more biofilm mass than the T6SS-negative isolates (mean ± standard deviation [SD], 0.3 ± 0.09 vs.0.16 ± 0.06; P < 0.01). Compared to the T6SS-negative isolates, the T6SS-positive isolates had a higher frequency of virulence genes (rmpA, fimH, entB, kfu, ybtS) and the pLVPK-like plasmid (P < 0.05). ConclusionIn conclusion, the prevalence of the type VI secretion system is high in clinical Klebsiella pneumoniae isolates in a Chinese teaching hospital. T6SS-positive strains show higher biofilm-forming activity with high drug resistance and exhibit higher virulence potential.

A case report of pyogenic liver abscess caused by hypervirulent Klebsiella pneumoniae diagnosed by metagenomic next-generation sequencing

A 56-year-old woman with a history of diabetes mellitus presented with high fever but no abdominal pain. An abdominal computed tomography scan showed a large liver abscess. Hypervirulent, string test-positive, rmpA/ampA2-, and iutA-positive Klebsiella pneumoniae was rapidly identified from drainage fluid of the liver abscess using metagenomic next-generation sequencing (mNGS). After intravenous antibiotic therapy and drainage of the abscess, the patient’s condition resolved. This case report highlights the value of mNGS in rapidly and accurately identifying a pathogenic microorganism, which helps reduce the incidence of antimicrobial resistance and enables the targeted use of antibiotics.

Clinical features and development of Sepsis in Klebsiella pneumoniae infected liver abscess patients: a retrospective analysis of 135 cases

BackgroundKlebsiella pneumoniae is a primary pathogen of pyogenic liver abscess (PLA). However, little data are available on combination with sepsis. In this study, we aimed to evaluate the clinical characteristics and prognostic differences of PLA patients with sepsis.MethodsThis retrospective cohort study was conducted to investigate 135 patients with confirmed Klebsiella pneumoniae-caused liver abscesses (KPLA) from a tertiary teaching hospital, from 2013 to 2019. The patients were divided into two groups, KPLA with sepsis and KPLA without sepsis. The demographic characteristics, clinical features as well as laboratory and microbiologic findings were analyzed.ResultsA total of 135 patients with KPLA were analyzed. The mean age of patients was 60.9 ± 12.7 years, and the percentage of men was 59.3%. Among them, 37/135 (27.4%) of patients had sepsis and the mortality rate was 1.5%. The most common symptom was fever (91.1%). KPLA patients with sepsis had a significantly higher proportion of frailty, diarrhea, fatty liver, chronic renal insufficiency, and hepatic dysfunction compared to KPLA patients without sepsis (p < 0.05). Antibiotic therapy and percutaneous drainage were most frequently therapeutic strategy. Furthermore, the incidences of sepsis shock and acute respiratory distress syndrome were higher in the sepsis group compared to the non-sepsis group. As for metastatic infections, the lung was the most common site. In addition, KPLA patients with sepsis showed respiratory symptoms in 11 patients, endophthalmitis in 4 patients, and meningitis in 1 patient.ConclusionOur findings emphasize that KPLA patients combined with or without sepsis have different clinical features, but KPLA patients with sepsis have higher rates of complications and metastatic infections. Taken together, further surveillance and control of septic spread is essential for KPLA patients.

Utility of Acute Physiology and Chronic Health Evaluation (APACHE II) in Predicting Mortality in Patients with Pyogenic Liver Abscess: A Retrospective Study.

Pyogenic liver abscess (PLA) is a major life-threatening disease with varied clinical features. This study aimed to determine predictors of mortality in patients with PLA using criteria determined upon admission. We retrospectively examined the data of 324 hospitalized adults in whom liver abscesses were confirmed using abdominal ultrasound and/or computed tomography. The relationship between various risk factors was assessed using multivariate analysis. A total of 109 (33.6%) patients were admitted to the intensive care unit (ICU). The overall mortality rate was 7.4% and was higher among ICU patients than non-ICU patients (21.1% vs. 0.5%, p < 0.001). PLA patients with an Acute Physiology and Chronic Health Evaluation (APACHE) II score ≥18 had a 19.31-fold increased risk, and those with concomitant infections had a 34.33-fold increased risk of 30-day mortality according to multivariate analysis. The estimated area under the receiver operating characteristic curve for predicting 30-day mortality revealed that APACHE II score ≥18 (sensitivity of 75% and specificity of 84%, p < 0.0001) had better discriminative power than Sequential Organ Failure Assessment (SOFA) ≥6 (sensitivity of 81% and specificity of 66%, p < 0.0001). APACHE II has shown better discrimination ability than SOFA in predicting mortality in PLA patients. To improve outcomes in patients with PLA, future management strategies should focus on high-risk patients.

Importation of Entamoeba histolytica and predominance of Klebsiella pneumoniae in liver abscesses: a 7-year retrospective cohort study from the United Arab Emirates

BackgroundThere is a dearth of information on liver abscesses in the United Arab Emirates. Herein, we describe the clinical features of liver abscesses and determine their incidence rates and clinical outcomes.MethodsWe retrospectively reviewed the clinical charts of adult patients with a primary diagnosis of liver abscess at a major hospital over a 7-year period.ResultsAmongst 45 patients, 82.2% (37/45) had a pyogenic liver abscess (PLA) and 17.8% (8/45) had amoebic liver abscesses (ALA). Overall, patients were young (median age 42 years, IQR 35–52), mostly males (77.8%, 35/45) from the Indian subcontinent (55.6%, 25/45), presented with fever (88.9%, 40/45) and abdominal pain (88.9%, 40/45), and had a solitary abscess on imaging (71.1% (32/45). Crude annual incidence rates were 35.9/100,000 hospital admissions (95% CI 26.2–48.0) and 5.9/100,000 inhabitants (95% CI 4.3–7.9). All ALA patients were from the Indian subcontinent (100%, 8/8). Klebsiella pneumoniae was the most frequent pathogen in PLA (43.2% [16/37], 95% CI 27.1–60.5%). The hospital stay was shorter in ALA (7.5 days, IQR 7–8.5) than in PLA (14 days, IQR 9–17). No deaths were recorded within 30 days of hospitalisation.ConclusionsALA was exclusively seen in migrants from the Indian subcontinent, suggesting importation. Further research to characterise K. pneumoniae isolates and assess potential risk factors is needed.
