Liver abscess as a rare complication of Crohn's disease: a case report.

Pyogenic liver abscess is a rarely seen extraintestinal complication of Crohn's disease. It has different features from other liver abscesses. Its clinical and laboratory findings are not specific and mimic the reactivation of Crohn's disease and diagnosis can be delayed. The radiological methods are very useful in diagnosis and treatment of liver abscess. In this paper, we present a patient with pyogenic liver abscess which developed in the course of Crohn's disease.

[Gas-containing hepatic abscess from an unusual etiology].

Pyogenic hepatic abscesses used to be caused by an abdominal infection. Cholangitis due to stones is the commonest cause, followed by diverticulitis or appendicitis. Most patients presenting with pyogenic liver abscesses have a polymicrobial infection usually with Gram negative aerobic and anaerobic organisms. Escherichia coli or Klebsiella pneumoniae are frequently implicated but they do not usually produce gas into the abscesses. We comment a case of a gas-containing liver abscess after an acute pancreatitis without any risk factor associated.

Staphylococcal liver abscess and acute cholecystitis in a patient with Crohn's disease receiving infliximab.

We present an unusual case of empyema of the gallbladder associated with a pyogenic liver abscess in a patient with Crohn's disease on Infliximab. It manifested by weakness, weight loss, and vague abdominal pain, which eventually localized to the right upper quadrant 4 days prior to admission. Diagnostic evaluation, which included ultrasonography and computed tomography, revealed cholelithiasis, gallbladder wall thickening, and a low-attenuation, complex mass in the left hepatic lobe. Cholecystectomy and open drainage of the liver abscess were successfully performed. There are few reports of intrahepatic abscess associated with Crohn's disease. The relationship between acute cholecystitis and Crohn's disease has also been documented. However, this report documents the unusual complication of pyogenic liver abscess secondary to acute cholecystitis in the unique population of Crohn's disease patients on Infliximab.

[Clinical significance of Klebsiella pneumoniae in liver abscess].

BACKGROUND/AIMS: Klebsiella pneumoniae (K. pneumoniae) has been emerging as the leading cause of liver abscess although the most common pathogen was Escherichia coli in the past. Our study was to clarify the significance of K. pneumoniae as a pathogen of pyogenic liver abscess. METHODS: We reviewed 157 cases of pyogenic liver abscess treated at Yeungnam University Hospital from 1996 to 2001. They were classified into two groups: K. pneumoniae group and non-K. pneumoniae group. The clinical presentations, characteristics of liver abscess, laboratory findings and the results of bacteriological studies were compared. RESULTS: The K. pneumoniae group included 60 (60.6%) cases among 99 cases with positive culture. We found higher incidence of alcoholics (45.0%) or diabetes millitus (35.0%) in K. pneumoniae group. Cryptogenic cause (61.7%) was the most frequent portal entry in K. pneumoniae liver abscess. On the other hand, in non-K. pneumoniae group, the cause of portal entry was usually the secondary (23.1%) following biliary disease (61.5%). Statistically, there was no significant difference in age, sex, symptom, characteristics of abscess, laboratory findings except total bilirubin level between the two groups. CONCLUSIONS: Liver abscess caused by K. pneumoniae has emerged as an important infectious disease with new clinical significance. When clinicians see pyogenic liver abscess in patients with alcoholics or diabetes millitus, K. pneumoniae should be considered first as a cause of liver abscess.

Papillon Lefevre syndrome.

Papillon Lefèvre syndrome is a rare disease characterized by skin lesions caused by palmar-plantar hyperkeratosis, and severe periodontal destruction involving both the primary and permanent dentitions. It is transmitted as an autosomal recessive condition and consanguinity of parents is evident in about one-third of cases. Pyogenic liver abscess is an increasingly recognized complication. We report a new case of this association and review the current literature.

Pyogenic abscesses and parasitic diseases.

Parasitic diseases which during their course in the host switch the immune system from a T helper 1 to a T helper 2 response may be detrimental to the host, contributing to granuloma formation, eosinophilia, hyper-IgE, and increased susceptibility to bacterial and fungal infections. Patients and animals with acute schistosomiasis and hyper-IgE in their serum develop pyogenic liver abscess in the presence of bacteremia caused by Staphylococcus aureus. The Salmonella-S. mansoni association has also been well documented. The association of tropical pyomyositis (pyogenic muscle abscess) and pyogenic liver abscess with Toxocara infection has recently been described in the same context. In tropical countries that may be an interesting explanation for the great morbidity of bacterial diseases. If the association of parasitic infections and pyogenic abscesses and/or fungal diseases are confirmed, there will be a strong case in favor of universal treatment for parasitic diseases to prevent or decrease the morbidity of superinfection with bacteria and fungi.

Neonatal hepatic abscess in preterm infants:a rare entity?

INTRODUCTION AND OBJECTIVE: Neonatal pyogenic hepatic abscess in preterm infants is a rare entity. We present 6 cases of neonatal liver abscesses diagnosed in our hospital as well as an approach that will facilitate the early diagnosis and management of neonatal pyogenic liver abscess based on our case series and review of the literature. MATERIALS AND METHODS: Retrospective review of case records of all 6 patients diagnosed with neonatal liver abscess from January 2000 to December 2002 in KK Women's and Children's Hospital, Singapore. RESULTS: All neonates were premature with gestational ages between 24 and 34 weeks. Persistence of positive blood culture despite appropriate antibiotic treatment in 67% of the cases prompted use of hepatobiliary ultrasounds to detect liver abscess. Surgical drainage of liver abscess was performed in 33% of the cases, with the remainder treated conservatively with appropriate intravenous antibiotics. Half of the infants recovered with resolution of their liver abscess on serial hepatobiliary ultrasound. The other half died of fulminant sepsis. CONCLUSIONS: Neonatal pyogenic liver abscess, though rare, is associated with good outcome if diagnosed promptly and appropriate treatment instituted. In a preterm infant with sepsis, a high index of suspicion is required if there is persistence of positive blood culture despite appropriate antibiotic treatment, and hepatobiliary ultrasound should be done to detect and monitor neonatal liver abscess.

Spontaneous gas-forming liver abscess caused by Salmonella within hepatocellular carcinoma: a case report and review of the literature.

In conclusion, pyogenic liver abscess in hepatocellular carcinoma is unusual. Most of the reported cases occurred after a treatment such as transcatheter arterial embolization or percutaneous ultrasound-guided ethanol injection. Salomonella very rarely causes pyogenic liver abscesses. Only 14 cases have been reported in the English literature since 1911. Salmonella liver abscess occurring within a primary neoplasm is even rarer. There were only two such cases described in patients with hepatocellular carcinoma before. The present case is the third one, but it may be the first case of obvious spontaneous gas-forming liver abscess caused by Salmonella within hepatocellular carcinoma.

Experimental anaerobic liver abscess: observations on treatment.

Various treatment modalities for solitary anaerobic liver abscesses were evaluated in a recently-described rabbit model. In the first phase of the experiment, 35 rabbits with liver abscesses induced with Bacteroides fragilis and Fusobacterium necrophorum were randomized into four groups: surgical drainage alone, drainage plus clindamycin 150 mg IM 8-hourly, clindamycin alone, and untreated controls. Serum clindamycin concentrations in rabbits were similar to those achieved in humans. The survival of rabbits receiving antibiotic chemotherapy alone was significantly better than controls, whereas the survival of those having surgical drainage with or without chemotherapy was not. However, successful surgical drainage was followed by weight gain in surviving rabbits. In the second phase of the experiment 18 rabbits with abscesses were randomized into the same groups. Aspirates of pus from all rabbits receiving clindamycin were sterile by day 7 of treatment, but high bacterial counts were still present in the abscess cavities of control rabbits and of those undergoing drainage alone. These findings illustrate the application of a new model for pyogenic liver abscess in laboratory investigation. Their relevance to management of human pyogenic liver abscesses remains to be assessed.

[Hepatic abscesses: is simple aspiration puncture with echography control an alternative to catheter drainage?].

UNLABELLED: Percutaneous drainage is currently the treatment of choice in liver abscess. The most commonly used technique is catheter placement but this procedure is not free of complications. OBJECTIVE: To analyze the safety and efficacy of needle aspiration in the treatment of liver abscesses. PATIENTS AND METHODS: Non-random, prospective study of nine patients with pyogenic liver abscess who underwent simple needle aspiration with sonographic guidance. RESULTS: In all patients, aspiration identified the etiologic agent. In eight patients (88.9%) the procedure was effective and in the remaining patients, the abscess was finally drained by sonographically guided catheter placement. In five patients, aspiration was successful at the first attempt and only one abscess required more than two attempts. No complications were observed. CONCLUSIONS: In our experience, needle aspiration with sonographic guidance is safe and effective in the treatment of pyogenic liver abscesses. Use of catheters is reserved for cases of rapid reaccumulation of exudate without general improvement in the patient.

Klebsiella and E. coli liver abscess associated with aerobilia: a case report.

Pyogenic liver abscesses are commonly caused by biliary tract infections. We report here a case of liver abscess developed secondary to a biliary-enteric fistula. A 83 year old diabetic woman was admitted because of sepsis due to Klebsiella pneumoniae and E. Coli and with upper right quadrant pain. Six months before admission, a laparoscopic cholecystectomy was performed. The abdominal sonography showed a liver abscess associated with an important aerobilia. The Magnetic Resonance Cholangiography showed a choledocho-colic fistula with an important inflammatory background. There was no evidence of neoplasia or inflammatory bowel disease. The evolution was marked by the development of urinary and bronchial tract infection due to Klebsiella. Septic metastasis are characteristics of Klebsiella liver abscesses. Percutaneous drainage associated with a intravenous antibiotherapy was performed.

Liver abscess caused by an infected ventriculoperitoneal shunt.

Pyogenic liver abscess in Taiwan is most commonly due to Klebsiella pneumoniae infection in diabetic patients, and less frequently due to biliary tract infections. Liver abscess caused by ventriculoperitoneal (VP) shunt is very rare. We report a case of liver abscess caused by methicillin-resistant Staphylococcus aureus (MRSA), which developed as a complication of an infected VP shunt. A 53-year-old woman, who had shad a VP shunt implanted 3 months previously for hydrocephalus due to intracranial hemorrhage, presented with fever off and on, drowsiness and seizure attacks for 1 week. Computed tomography (CT) of the brain showed only mild right-sided hydrocephalus, and was negative for intracranial hemorrhage and intracranial mass. Analysis of cerebrospinal fluid showed significant pleocytosis and hypoglycorrhachia. CT scan of the abdomen disclosed a huge abscess in the right lobe of the liver. Cultures of both the cerebrospinal fluid and aspirated liver abscess isolated MRSA. The patient was treated with intraventricular and intravenous vancomycin, intravenous teicoplanin and oral rifampicin, followed by oral chloramphenicol and rifampicin. Percutaneous drainage of the liver abscess and externalization of the VP shunt were performed. The liver abscess had resolved almost completely on ultrasonography after 2 weeks of therapy. Liver abscess in patients with a VP shunt should be considered a possible abdominal complication of the VP shunt, and may be caused by unusual pathogens. Diagnosis requires CT scan and direct aspiration and culture of the liver abscess. Treatment requires management of both the liver abscess and the infected shunt.

A global emerging disease of Klebsiella pneumoniae liver abscess: is serotype K1 an important factor for complicated endophthalmitis?

BACKGROUND AND AIMS: Over the past two decades in Taiwan, pyogenic liver abscess has usually been caused by a single microorganism, Klebsiella pneumoniae, and is frequently associated with the serious complication of endophthalmitis, especially in diabetic patients. However, the relationship between the clinical presentation and bacterial factors remains unclear. The aim of this study was to investigate the clinical features of patients and the serotype and ribotype of K pneumoniae liver abscess. METHODS: From July 1991 to June 1998, a total of 134 cases of K pneumoniae liver abscess with 248 K pneumoniae isolates from the same patients were collected from two large medical centres in northern Taiwan. Clinical data were collected from medical records. Serotyping and ribotyping were performed using the countercurrent immunoelectrophoresis method and automated Riboprinter. RESULTS: Serotyping revealed that the most common serotypes were K1 (63.4%) and K2 (14.2%). K1 isolates occurred at a significantly higher frequency (p<0.01) than all other serotypes. Among 134 patients, 105 (78.4%) had suffered from diabetes mellitus for 3-15 years. Fourteen patients (10.4%) had metastatic infection to the eye causing septic endophthalmitis. Liver aspirates, and blood and vitreous pus cultures yielded the same serotype of K pneumoniae in all patients. Among patients with septic endophthalmitis, 92.3% (13/14) were diabetic, and 85.7% (12/14) of the isolates belonged to serotype K1. For molecular typing, different degrees of genetic polymorphism among isolates with the same K1 serotype suggested no particular prevalence of any one strain in K pneumoniae liver abscess. CONCLUSION: K pneumoniae serotype K1 was significantly associated with liver abscess and the complication of endophthalmitis, especially in diabetic patients. Physicians should request an immediate report of serotyping and susceptibility test results simultaneously if a diagnosis of pyogenic liver abscess has been made so that early and appropriate management for possible complications will not be delayed. The use of ceftriaxone because of its higher concentration in the aqueous humor is suggested to decrease the chance of septic endophthalmitis.

[A diagnostic approach to hepatic abscess].

BACKGROUND: The non invasive diagnosis of amebic liver abscess allows the use of empirical therapy without the requirement of invasive diagnostic procedures. AIM: To determine the discriminatory capacity of clinical, laboratory and ultrasound studies for the etiological diagnosis of liver abscess. PATIENTS AND METHODS: Sixty one patients were initially included in this prospective study, but 12 did not comply with the inclusion criteria. Of the rest, 29 (59%) had an amebic liver abscess, 16 (33%) had a pyogenic liver abscess and four (8%) had an abscess of mixed etiology. Blood cultures were done in 42 patients. Ultrasound guided needle aspiration was done in 7 patients with amebic liver abscess and 13 patients with non amebic liver abscess. RESULTS: The clinical picture and ultrasound findings were similar in all types of amebic abscess. ELISA test for IgG anti-Entamoeba histolytica antibodies were positive in 100% of patients with amebic liver abscess. Antibodies measured by gel diffusion were positive in 93%. All patients with mixed liver abscess had positive antibodies and some of them positive culture. Blood cultures were positive for anaerobic bacteria in five patients. Cultures of aspirated material were positive in 7 patients (obligate anaerobic bacteria in 3 and facultative anaerobic bacteria in the rest). The most common complications, whatever the etiology, were right pleural effusion and systemic inflammatory response. CONCLUSIONS: A final model of binomial regression analysis revealed that age under 40 years, an hematocrit greater than 35% and an elevation in prothrombin time of less than 1.5 seconds had enough discriminatory capacity for the diagnosis of amoebic liver abscess.

Surgical management of hepatic abscesses.

Amebic and pyogenic hepatic abscesses are rare liver lesions that may require surgical intervention. Amebic liver abscesses are more common in subtropical and tropical climates and in areas with poor sanitation. The majority of pyogenic liver abscesses are caused by infections in the biliary or intestinal tracts. These lesions can be differentiated on clinical grounds and by amebic serology. Ultrasound and computed tomography are the imaging techniques of choice. The initial management of amebic hepatic abscesses is treatment with amebicidal agents. Most patients respond rapidly so that surgery is reserved for patients with complications including secondary bacterial infection, impending rupture, or rupture into the pericardium or peritoneum. Patients with pyogenic hepatic abscesses require a prolonged course of antibiotics and appropriate drainage. Selected solitary abscesses can be managed with percutaneous abscess drainage. Similarly, some abscesses of biliary origin will respond to percutaneous biliary drainage. Surgical drainage has several advantages including: the ability to explore the abdomen for a source, excellent exposure of the entire liver, accurate assessment, sometimes with ultrasound, of the best drainage site, and access to the biliary tree for cholangiography and drainage.

Pyogenic hepatic abscess: a case for open drainage.

A retrospective review of 24 patients treated at the University of Chicago for pyogenic liver abscess from 1979 to 1989 was performed to determine if there is a changing etiology in pyogenic liver abscess and if percutaneous drainage is a reliable treatment alternative to open drainage. Biliary tract disease was the most common cause and presented in 29 per cent of patients. Klebsiella and enterococcus were the most common bacterial organisms cultured in 33 and 29 per cent of patients, respectively. The overall mortality rate was 25 per cent, however, if open drainage, in addition to a definitive procedure such as cholecystectomy or bowel resection was performed, there were no deaths. We therefore recommend the use of percutaneous drainage alone only in selected patients.

Portal vein thrombosis and liver abscess due to Lactococcus lactis.

A 26-year-old man was admitted with fever and abdominal pain. Abdominal ultrasonography and Doppler ultrasound eventually revealed portal vein thrombosis and a pyogenic liver abscess (17x11x11 cm). Lactococcus lactis was isolated from a culture of the abscess material. This organism is not a common pathogen in humans. This is the first published description of portal vein thrombosis and pyogenic liver abscess due to L. lactis.

Gas-forming liver abscess following transcatheter hepatic arterial embolization for an iatrogenic intrahepatic pseudoaneurysm: report of a case.

We herein describe a case of gas-forming pyogenic liver abscess following transcatheter hepatic arterial embolization (THAE) for an iatrogenic intrahepatic pseudoaneurysm in a 74-year-old woman. Hemobilia developed 19 days after percutaneous transhepatic cholangio-drainage was performed for the purpose of percutaneous cholangioscopic lithotripsy for the treatment of post-gastrectomy choledocholithiasis. Celiac arteriography disclosed a saccular aneurysm in the right hepatic artery. The pseudoaneurysm was successfully occluded by THAE with gelatin powder and a stainless steel coil of the Gianturco type. Ten days after successful THAE, abdominal computed tomography revealed a gas-containing cavity, which suggested the presence of a gas-forming abscess, in the posterior hepatic segment, and percutaneous transhepatic abscess drainage was performed. Thus, impaired hepatic perfusion following effective THAE and coexisting cholangitis may play an important role in the development of a gas-forming pyogenic liver abscess.
