Pyogenic liver abscesses in a child spreading to pulmonary and subcutaneous tissues: case report.

Pyogenic liver abscess is a rare and life-threatening disease in children. Our case is noteworthy because of the rapid advancement of liver abscesses without any other systemic disorder. A 16-year-old girl was admitted to the hospital with fatigue, pallor, weight loss and high fever. In physical examination a fluctuating mass was observed under the scapular area and hepatosplenomegaly was found. In computed tomography, three septated cystic lesions which looked like abscesses were demonstrated in the liver. The abscess was drained through percutaneous route. Right pleural empyema with clinical features of adult respiratory distress syndrome appeared after the first day of treatment. Bacteroides sp. was isolated from pus. On the twentieth day of the therapy, control abdominal computed tomography revealed two new abscesses in the liver. They were drained and the antibiotic therapy was continued with ticarcillin-clavulanate, fluconazole and levofloxacin. By the end of the first week of the therapy, the fever of the patient had abated. This therapy was continued for four weeks; 15 days after the end of the therapy there was prominent healing of the liver lesions with only one necrotic remnant 2 cm in diameter on abdominal computed tomography.

Causal bacteria of pyogenic liver abscess.

This is a review of bacteriologic data on 175 patients with pyogenic liver abscesses seen over a period of 8 years at Veterans General Hospital, Taipei, Taiwan. Positive cultures were obtained from liver aspirates in 151 of the 163 patients in which cultures were taken. One hundred and twenty patient specimens grew one isolate and 31 specimens grew two or more isolates. A total of 149 aerobic gram-negative rods, 25 aerobic cocci and 29 anaerobes were isolated. Ninety of the 159 patients from whom blood was taken had positive cultures. In 11 patients, two or more isolates were grown concurrently from the blood. A total of 87 aerobic gram-negative rods, 7 aerobic cocci and 10 anaerobes were isolated. Klebsiella pneumoniae was the most common microorganism, accounting for 50.8% of the cases. Other major pathogens were Escherichia coli (27.4%), anaerobes (15.4%), and viridans streptococci (6.2%).

Pyogenic liver abscess--a tropical centre's experience in management with review of current literature.

AIM OF STUDY: To perform a retrospective study, with the help of literature review, of the management of patients with pyogenic liver abscess in a general hospital. METHOD: A retrospective study of 73 consecutive patients treated atTanTock Seng Hospital between January 1994 and December 1997 was conducted to determine the demographic, clinical, laboratory, radiological and microbiological characteristics of these patients, as well as the management strategies employed. RESULTS: Liver abscess was more common in males, occurring more frequently in the right hepatic lobe. Most patients presented with non-specific clinical and biochemical features. A raised alkaline phosphatase level was the most common biochemical abnormality found in about two-thirds of patients. Ultrasonography was not as sensitive as computed tomographic scans in detecting abscesses. Klebsiella pneumoniae was the most common etiological agent detected in cultures of blood and abscess aspirates. All patients were treated with intravenous antibiotics. Twenty-two (30%) needed percutaneous catheter drainage and five (7%) required surgical management. There was no hospital mortality in our series. Prolonged hospitalisation was associated with advanced age, degree of loculation within the abscess, concomitant diabetes mellitus and Klebsiella septicaemia. CONCLUSION: Pyogenic liver abscesses require a high index of suspicion for early diagnosis. When appropriate therapy in the form of antibiotics in combination with percutaenous drainage or surgery is administered, mortality is very low. However, significant morbidity is still a problem, particularly in the elderly, diabetic patient.

A case of glomerulonephritis in association with pyogenic liver abscess.

Glomerulonephritis associated with visceral abscess is being increasingly recognized. The association of glomerulonephritis with visceral suppuration in the absence of endocarditis was first described by Whitworth and associates. Abscesses were most frequently located in the respiratory tract but have been reported at numerous other sites, including appendix, uterus, aorto-femoral bypass graft and cutaneous wound. This report documents the apparently rare occurrence of glomerulonephritis with acute renal failure in association with pyogenic liver abscess. The need for awareness of glomerulonephritis as a cause of acute renal failure in pyogenic liver abscess is highlighted.

Percutaneous drainage of pyogenic liver abscesses.

This report summarizes the results of percutaneous catheter drainage in 23 cases of primary or secondary pyogenic liver abscess. The overall success rate was 76%. Only three (60%) of five cases of secondary abscess (infected hematoma or infected tumor) were cured with catheter drainage, but 11 (91%) of the last 12 primary pyogenic abscesses were drained successfully. Six patients with abscesses of less than 4 cm in diameter required catheter drainage for less than 72 hr. Although six abscesses in the series appeared septated or multiloculated, only one required more than a single catheter for curative drainage. Diagnostic and technical considerations for successful drainage of hepatic abscesses are discussed. The differential diagnosis includes echinococcal disease and hepatic amebiasis. Therapeutically, specific measures should be taken to ensure proper catheter position to prevent contamination of the subphrenic, perihepatic, and pleural spaces. Percutaneous catheter drainage should be attempted as a first choice of treatment in all pyogenic hepatic abscesses.

Hypervirulent Klebsiella pneumoniae ST23 causing pyogenic liver abscess and metastatic endogenous endophthalmitis in Europe: a case report.

INTRODUCTION AND IMPORTANCE: Pyogenic liver abscess (PLA) has traditionally been considered prevalent in Asia. However, its incidence is increasing in Europe. Klebsiella pneumoniae (Kp) has emerged as the leading causative pathogen, and hypervirulent strains pose a higher risk of invasive disease and metastatic complications, such as endogenous endophthalmitis (EE). CASE PRESENTATION: The case describes a 77-year-old woman who presented with fever and right upper quadrant abdominal pain. She was diagnosed with a second episode of PLA within 3 months, caused by Kp. Despite prompt antimicrobial therapy and percutaneous transhepatic drainage, the patient developed acute vision loss in the left eye during hospitalization. Ophthalmologic assessment confirmed EE secondary to bacteremia. Whole-genome sequencing identified the isolate as hypervirulent Kp (hvKp) sequence type 23 (ST23). While the liver abscess resolved following treatment, the patient sustained permanent loss of vision in the affected eye despite aggressive medical and surgical management. CLINICAL DISCUSSION: This case illustrates the invasive nature of hvKp and its potential for recurrence and metastatic complications. Improved recognition through targeted virulence testing is essential to avoid underdiagnosis. CONCLUSION: This case highlights the aggressive nature of hvKp. Early recognition of systemic and ocular symptoms, prompt ophthalmologic evaluation, and timely source control are essential. Optimal management requires multidisciplinary collaboration and the use of molecular diagnostics, including whole-genome sequencing, to identify hypervirulent lineages and support surveillance.

Clinical significance and mechanism of gas formation of pyogenic liver abscess due to Klebsiella pneumoniae.

We enrolled 22 patients with gas-forming pyogenic liver abscess in a study to assess the mechanism of gas formation. Klebsiella pneumoniae was cultured from specimens from all patients. Gas and pus samples from abscesses revealed four major components: nitrogen, oxygen, carbon dioxide, and hydrogen; this implicates mixed acid fermentation of glucose as the mechanism of gas formation.

Pyogenic liver abscess.

A retrospective study of 18 adults admitted to Meir General Hospital with pyogenic liver abscess during the years 1982-88 was conducted. Our most useful diagnostic tool was ultrasound, which was accurate in all 15 patients in whom it was performed. Only two patients presented with multiple abscesses. Increased alkaline phosphatase was the most predictive laboratory finding, seen in all but one patient. One person was treated conservatively by antibiotics only. In one patient the abscess drained spontaneously into the right thoracic cavity. Initial surgical drainage was done in nine patients and percutaneous catheter drainage in seven. Only one patient died, of septic shock, yielding a mortality rate of 5.5%. The treatment-related complication rate, observed in almost half of the patients, was high. All patients with such complications required repeated drainage, which was achieved surgically in all cases.

Single and multiple pyogenic liver abscesses: clinical course, etiology, and results of treatment.

A total of 483 patients with pyogenic liver abscess during the years 1986 to June 1995 were studied at Chang Gung Memorial Hospital in Kaohsiung: 343 were a single abscess and 140 were multiple abscesses. Males were predominantly affected by this disease. Abdominal pain was more frequent with the single abscess than with multiple abscesses, and jaundice was more frequent with multiple abscesses. Blood levels of alkaline phosphatase, bilirubin, and creatinine and the white blood cell count were significantly higher in patients with multiple abscesses than in those with a single abscess; and the hemoglobin level was higher with single abscesses. The single abscess was usually larger than 5 cm, and the multiple abscesses were usually smaller than 5 cm. The single abscess was always located on the right side (72%) and the multiple abscesses always on the right or both sides. Single abscesses mainly had a cryptogenic origin (58.9%) and multiple abscesses a biliary origin (45.0%). Liver aspirates revealed Klebsiella pneumoniae, Escherichia coli, Streptococcus, Bacteroides, Enterococcus, among others. K. pneumoniae was more often found in a single abscess and E. coli more often in multiple abscesses. Percutaneous catheter drainage and aspiration comprised the main treatment initially, and the failure rate with multiple abscesses was higher than that with single abscesses. Surgical intervention should be considered for multiple abscesses because of the underlying disease. The overall mortality with multiple abscesses (22.1%) was higher than that with a single abscess (12.8%). Partial hepatectomy produced a low mortality rate for both single and multiple abscesses and should be considered in the presence of severe hepatic destruction by an abscess or a stone.

Pyogenic liver abscess caused by Pseudomonas aeruginosa in a previously healthy child: report of one case.

Pyogenic liver abscess (PLA), a very uncommon liver disease in the normal pediatric group is often associated with immunocompromised conditions. Pseudomonas aeruginosa has long been regarded as a relatively rare pathogen of PLA, especially in patients without underlying problems. A previously healthy one-year-and-seven-month-old boy who had symptoms of fever, vomiting and diarrhea got a liver abscess at right hepatic lobe which was confirmed by abdominal ultrasound and computed tomography (CT) diagnoses. Ultrasound-guided percutaneous aspiration of liver abscess was done soon after the confirmation. The culture result of aspirate grew P. aeruginosa. The patient received a 4-week course of adequate antibiotics treatment after the aforementioned aspiration procedure. In addition, a series of ultrasounds were performed to follow the resolution of abscess during the treatment period. The immune function tests of the patient were within normal ranges. Finally, the lesion resolved completely without leaving any complication.

Clinical aspects of pyogenic liver abscess: the University Hospital of the West Indies experience.

Twenty-four cases of pyogenic liver abscess admitted between 1977 and 1986 are presented. A mean age of 43 years (range 5-78) with a 3:1 male:female ratio and 25% mortality were noted. Fever and abdominal pain were encountered in over 80% of cases and anorexia and malaise in over 60%. Hepatomegaly and right upper quadrant tenderness were the commonest signs. Leucocytosis, raised alkaline phosphatase and gamma-glutamyl transpeptidase, and hypoalbuminaemia were each noted in roughly 80% of cases. None of these showed any prognostic significance. Predisposing factors were noted in 11 cases. No cases of associated biliary disease were noted. Multiple, polymicrobial, aerobic and mixed aerobic/anaerobic abscesses were associated with a higher mortality. Patients aged over 50 years or more also had a higher mortality (P less than 0.05). Anaerobic abscesses were often solitary and were associated with a lower mortality (P less than 0.05). Surgical drainage and guided percutaneous drainage showed no difference in morbidity.

Pyogenic liver abscess complicating common bile duct stenosis secondary to chronic calcific pancreatitis. A rare presentation.

Pyogenic liver abscess is a rare presentation of common bile duct stenosis secondary to chronic calcific pancreatitis. Two cases are described in this report; in both cases, biliary obstruction was present in the absence of jaundice. Successful therapy of the abscesses was accomplished with antibiotics alone and without continuous percutaneous drainage or surgical intervention. Definitive therapy should include eventual surgical correction of the biliary obstruction.

Pyogenic liver abscess: a study of forty-four cases in two centres.

44 patients with pyogenic liver abscess, 22 each from Leicester, UK, and Göteborg, Sweden, presenting between 1972 and 1980 have been reviewed. 29 patients were diagnosed prior to specific treatment with 3 deaths (10%); 15 patients were first discovered at autopsy resulting in an overall mortality of 41%. The presentation, pathogenesis, and treatment are discussed in detail. It is concluded that the continuing high mortality of this condition largely relates to the difficulty in establishing the diagnosis. Reduced morbidity (and perhaps mortality) might be achieved with wider use of percutaneous methods of drainage.

Intestinal nematodes, Toxocara infection, and pyogenic liver abscess in children: a possible association.

Eosinophilia and intestinal helminths are frequent in children with pyogenic liver abscess (PLA) diagnosed in Vitória (Brazil). For these reasons we hypothesized that nematode infection with larvae migrating through the tissues (Ascaris, Strongyloides, Ancylostoma, Necator and Toxocara) may be a predisposing factor for PLA in children. We compared the prevalence of intestinal helminth and Toxocara infection between children with PLA and a control group of children with no evidence of PLA at the Children's Hospital N.S. da Glória in Vitória. From October 1996 to February 1998, 13 children with PLA and 110 children with diseases other than PLA provided five stool samples (Hoffman, Baerman and Kato-Katz methods) and one blood sample for anti-Toxocara antibodies (ELISA IgG, with previous adsorption with Ascaris suum antigen). All PLA and comparison children belonged to a low socioeconomic class and lived in similar conditions. The frequency of intestinal nematodes and anti-Toxocara antibodies were significantly higher in PLA patients than in controls (intestinal helminths: 10/13 or 76.9 per cent in PLA cases and 31/110 or 28.1 per cent in controls; OR = 8.94; 95 per cent confidence interval (CI): 1.97 < OR < 50.06; anti-Toxocara antibodies: 9/13 or 69.2 per cent in PLA and 31/110 or 28.1 per cent in controls; OR = 6.59; 95 per cent CI: 1.65 < OR < 31.05). Moreover, the degree of eosinophilia was higher in PLA patients. Malnutrition was present in both groups. Hemoglobin was 9.5 g/dl in PLA patients and 9.7 g/dl in controls; p = 0.900. Serum levels of IgA and IgM were normal or above normal, with no difference between the two groups, but the levels of IgG and IgE were higher in PLA patients. Although there is some missing data in respect to some socioeconomic parameters in affected and comparison groups. these results support the hypothesis that helminth infection with larvae migrating through tissues may be a predisposing factor for PLA in children. Th2 cell activation and downregulation of Th1 cells, induced by helminths, thus reducing the microbicidal activity of phagocytes, as well as the granulomatous reaction around the larvae (mainly of Toxocara sp.) causing the trapping of bacteria in liver, may be possible explanations for the increased risk for PLA in children with intestinal nematodes and/or Toxocara infection.

Elective one-stage abdominal operations after percutaneous catheter drainage of pyogenic liver abscess.

During the past 10 years, 15 patients have had percutaneous catheter drainage (PCD) of pyogenic liver abscesses (PLA) at a major teaching hospital. Five PLA were related to biliary tract disease, two were secondary to colonic diverticulitis, two developed after abdominal surgery, and the remaining were associated with hepatic trauma, gastric ulcer, Crohn's ileitis, and colon cancer. Two abscesses were cryptogenic. Mean diameter of PLA was 8 cm and ranged from 2-14 cm. Three patients had multiple PLA. All patients were initially treated by PCD without major complications. However, one patient required a second PCD after developing a recurrent abscess. Fever and leukocytosis defervesced at a mean 3.6 days and 7 days, respectively, after PCD. Seven of the 15 patients subsequently had one-stage elective abdominal operations for treatment of diseases underlying PLA including two cholecystectomies, two colon resections, one gastrectomy, one ileostomy closure, and one laparotomy for unresectable gall bladder cancer. There were no postoperative complications. These results demonstrate that PLA are best treated by using PCD as primary treatment with surgical drainage reserved for patients who do not respond clinically to PCD. The need for operative treatment in diseases underlying PLA should not deter use of PCD as primary treatment.

[Pyogenic liver abscess: a caseload contribution].

Pyogenic hepatic abscesses have been recognized since the time of Hippocrates, but an understanding of their etiology, bacteriology, diagnosis and treatment is an event of the twentieth century. Fortunately mortality rate has declined due to improvements in diagnosis, intensive care, medical and surgical management. In particular, the use of CT and ultrasound scanning has reduced the incidence of unrecognized and therefore untreated liver abscesses. Considering nine patients operated on for liver abscess, the Authors affirm that laparotomic surgical drainage is still the most effective therapy in the majority of cases.
