[Listeria monocytogenes liver abscess. In a diabetic patient].

Most liver abscesses are caused by Enterobacteriaceae, sometimes associated with anaerobes. Listeriosis is an exceptional cause of liver abscess, usually in a context of disseminated infections. We report the case of a diabetic woman who had liver abscess due to Listeria monocytogenes. The organism was isolated after guided needle aspiration, and there was no other site of infection. The course of the disease gradually moved towards recovery under an antibiotic therapy that was based on sensitivity tests. A search for immunodeficiency proved negative. A review of the literature showed that the rare cases of listerial liver abscess share a common factor, diabetes mellitus, the importance of which has not yet been noticed.

[Liver abscesses as a complication of Crohn's disease].

Liver abscesses were found in two women aged 23 and 34 years who suffered from Crohn's disease. The first patient was seen because of fever and thoracic pain and had been treated with infliximab. The second patient, who was pregnant, presented with abdominal pain that was thought to be due to an exacerbation of her inflammatory bowel disease. Ultrasonography and CT revealed that both patients had large liver abscesses. Both received antibiotic treatment, the first patient underwent drainage of the abscess, and the second underwent puncture twice, resulting in clinical improvements in both patients. In contrast to intra-abdominal abscesses, liver abscesses are rarely seen in patients with Crohn's disease. The clinical presentation can be mistaken for an exacerbation of Crohn's disease, but the diagnosis can be made easily using ultrasonography or CT. Treatment consists of (ultrasound-guided) percutaneous drainage and administration of antibiotics.

[The diagnosis and treatment of liver abscesses].

An analysis of results of treatment of 15 patients with abscesses of the liver of different genesis is given in the article. The ultrasonic method of examination was shown to be highly efficient for diagnosis of liver abscesses. The authors stress the necessity of differential approach to treatment of such patients based on etiopathogenesis of the disease. In most cases the method of choice for treatment of liver abscesses was found to be the percutaneous puncture and drainage under control of echography.

[Sonographic percutaneous drainage of liver abscesses].

13 patients with pyogenic liver abscess and five patients with amoebic abscess underwent percutaneous drainage of the abscesses using the Seldinger (n = 8) or trocar technique (n = 11). The results showed that the trocar method was easier and faster to perform and well tolerated by the patients. No complications were observed despite of one case of transient peritonitis caused by a dislocated catheter. One patient with pyogenic liver abscess died of septic shock. All other patients were successfully treated, using local drainage and systemic antibiotic therapy.

Drug and immuno-diagnostic resistant amoebic liver abscess in Ibadan: an elucidation of a possible mechanism.

A thick fibrous walling of amoebic abscess of the liver is very rare. Using as a basis the case of drug and immunodiagnostic resistant amoebic liver abscess in an adult Nigerian, an account is given of the possible mechanisms for such therapeutic and diagnostic failure. A theory of blood-abscess cavity barrier is postulated and suggested as a mechanism for the constant failure to detect antibodies to E. histolytica in the small percentage of cases of amoebic liver abscess (Morris, Powell and Elsdon-Dew, 1970). A study of the rate of diffusion of amoebic excretion/secretion through a thick fibrous tissue or artificial membrane of comparable properties is strongly advocated.

Influence of a new prophylactic antibiotic therapy on the incidence of liver abscesses after chemoembolization treatment of liver tumors.

Intrahepatic abscess is a complication of transcatheter arterial chemoembolization (TACE) treatment in patients who have a history of biliary reconstructive surgery. This study followed eight patients who underwent chemoembolization after biliary surgery. These patients were divided into two groups. Patients in group one (n = 4) were administered intravenous cephalexin for prophylaxis. Patients in group two (n = 4) were administered bowel preparation and tazobactam/piperacillin. All patients in group one developed hepatic abscesses, which were treated with percutaneous catheter drainage and antibiotics. None of the patients in group two developed abscesses. Aggressive antibiotic prophylaxis with bowel preparation may provide protection against intrahepatic abscesses after chemoembolization in patients who have a history of biliary reconstructive surgery.

Pyogenic liver abscess associated with large colonic tubulovillous adenoma.

Pyogenic liver abscesses usually occur in association with a variety of diseases. Rarely, liver abscess has been reported as the presenting manifestation of colonic tubulovillous adenoma. We report two cases of pyogenic liver abscess without hepatobiliary disease or other obvious etiologies except that one had a history of diabetes mellitus (DM). The pathogen in the patient with DM was Klebsiella pneumonia (KP). In both of the patients, ileus developed about two to three weeks after the diagnosis of liver abscess. Colonoscopy revealed large polypoid tumors with pathological findings of tubulovillous adenoma in both cases. Two lessons were learned from these two cases: (1) an underlying cause should be aggressively investigated in patients with cryptogenic liver abscess; (2) DM could be one of the etiologies but not necessarily the only cause of KP liver abscess.

Pyogenic liver abscess caused by Burkholderia pseudomallei in Taiwan.

Pyogenic liver abscess in Taiwan is a well-known disease entity, commonly associated with a single pathogen, Klebsiella pneumoniae. Melioidosis is an endemic disease in Taiwan that can manifest as multiple abscesses in sites including the liver. We report three cases of liver abscesses caused by Burkholderia pseudomallei. The first patient was a 54-year-old diabetic woman, who presented with liver abscess and a left subphrenic abscess resulting from a ruptured splenic abscess, co-infected with K. pneumoniae and B. pseudomallei. The second patient, a 58-year-old diabetic man, developed bacteremic pneumonia over the left lower lung due to B. pseudomallei with acute respiratory distress syndrome, and relapsed 5 months later with bacteremic abscesses of the liver, spleen, prostate and osteomyelitis, due to lack of compliance with prescribed antibiotic therapy. The third patient was a 61-year-old diabetic man with a history of travel to Thailand, who presented with jaundice and fever of unknown origin. Liver and splenic abscesses due to B. pseudomallei were diagnosed. A high clinical alertness to patients' travel history, underlying diseases, and the presence of concomitant splenic abscess is essential to early detection of the great mimicker, melioidosis. The treatment of choice is intravenous ceftazidime for at least 14 days or more. An adequate duration of maintenance oral therapy, with amoxicillin-clavulanate or trimethoprim-sulfamethoxazole for 12-20 weeks, is necessary to prevent relapse. Liver abscess in Taiwan is most commonly due to K. pneumoniae, but clinicians should keep in mind that this may be a presenting feature of melioidosis.

A nationwide study of the incidence and 30-day mortality rate of pyogenic liver abscess in Denmark, 1977-2002.

BACKGROUND: Pyogenic liver abscess is a life-threatening disease. Accurate data on incidence and prognosis are important, but scarce. AIM: To examine changes in the incidence and 30-day mortality rate of patients with pyogenic liver abscess in Denmark. METHODS: Using nationwide administrative registers, we identified all patients diagnosed with pyogenic liver abscess in Denmark, 1977-2002, and their dates of death. We computed annual standardized incidence and 30-day mortality rates, and used Poisson regression to adjust gender-specific mortality rates for year-by-year differences in age at diagnosis. RESULTS: We identified 1448 patients with pyogenic liver abscess, of whom 54% were men. The crude incidence rate for the entire study period was 11.8 per 1,000,000 for men and 9.7 per 1,000,000 for women. Between 1977 and 2002, the incidence rate increased from 6 to 18 per 1,000,000 for men and from 8 to 12 per 1,000,000 for women. The cumulative 30-day mortality rate was 15% for men and 23% for women. The adjusted 30-day mortality rate decreased from 40% for men and 50% for women to around 10% for both genders. CONCLUSIONS: In this large nationwide study spanning a 26-year period, we found an increasing incidence rate and a decreasing mortality rate of pyogenic liver abscess. We believe that these changes are primarily explained by more sensitive diagnostic tools.

Primary liver abscess due to Klebsiella pneumoniae in Taiwan.

Pyogenic liver abscess is an uncommon complication of intra-abdominal or biliary tract infection and is usually a polymicrobial infection associated with high mortality and high rates of relapse. However, over the past 15 years, we have observed a new clinical syndrome in Taiwan: liver abscesses caused by a single microorganism, Klebsiella pneumoniae. We reviewed 182 cases of pyogenic liver abscess during the period September 1990 to June 1996; 160 of these cases were caused by K. pneumoniae alone, and 22 were polymicrobial. When patients with K. pneumoniae liver abscess were compared with those who had polymicrobial liver abscess, we found higher incidences of diabetes or glucose intolerance (75% vs. 4.5%) and metastatic infections (11.9% vs. 0) and lower rates of intra-abdominal abnormalities (0.6% vs. 95.5%), mortality (11.3% vs. 41%), and relapse (4.4% vs. 41%) in the former group. Liver abscess caused by K. pneumoniae is a new clinical syndrome that has emerged as an important infectious complication in diabetic patients in Taiwan.

Pyogenic liver abscess.

A review of 20 cases of pyogenic liver abscesses seen from 1971 through 1976 is presented. In this five-year interval, no amebic liver abscesses were found. The primary inflammatory processes were evenly divided among those patients with biliary, urinary, and intraperitoneal disease. Intensive antibiotic therapy was less efficient in sterilizing the abscess than the blood stream. The nebulous histories, clinical findings, and routine laboratory studies emphasize the difficulty in establishing an early diagnosis of liver abscess. Radioisotopic scanning of the liver proved to be the most reliable tool not only for the diagnosis but also for monitoring the postoperative course of the drained cavities. The overall mortality of pyogenic liver abscesses was 45% and the greatest mortality occurred in those patients over 40. Closed needle aspiration of pyogenic liver abscess in the elderly poor-risk patient in conjunction with the appropriate antibiotics may offer an acceptable alternative.

Microbiology of liver abscesses and the predictive value of abscess gram stain and associated blood cultures.

Although rare, pyogenic liver abscesses are potentially fatal. We evaluated the predictive value of Gram stain of liver abscess aspirates and temporally associated blood cultures. Gram stains detected bacteria in 79% of the liver abscesses tested. The sensitivity and specificity of Gram stain of the liver abscesses were 90% and 100% for Gram-positive cocci (GPC) and 52% and 94% for Gram-negative bacilli (GNB). The sensitivities of the blood cultures for any GPC and GNB present in the liver abscess were 30% and 39%, respectively. Although, Gram stains and blood cultures offer incomplete detection of the microbial contents of pyogenic liver abscesses, both tests should always accompany liver abscess cultures.

Liver abscesses due to Fusobacterium spp that mimick malignant metastatic liver disease.

A 71-year-old man presented with the clinical and radiological features of metastatic liver disease but subsequently was found to have multiple liver abscesses caused by Fusobacterium necrophorum. At liver biopsy, pus was aspirated and Fusobacterium necrophorum was isolated from the pus. Serial blood cultures and urine cultures were sterile and negative for Fusobacterium spp. The patient made a complete recovery in response to treatment with penicillin and amoxicillin. This case illustrates the importance of liver abscesses as an uncommon but completely treatable differential diagnosis for the radiological appearances of multiple hepatic lesions.

Antibodies to the serine rich Entamoeba histolytica protein (SREHP) prevent amoebic liver abscess in severe combined immunodeficient (SCID) mice.

Amoebic liver abscess caused by Entamoeba histolytica is a major cause of morbidity and mortality worldwide. We used mice with severe combined immunodeficiency (SCID mice) to study the role of antibody in protection from amoebic liver abscess, and to identify protective antigens of E. histolytica. Antisera to recombinant versions of two major surface antigens of E. histolytica, the serine rich E. histolytica protein (SREHP) and the 170 kDa adhesin were used in this study. We found that 100% of SCID mice passively immunized with antiserum to the recombinant SREHP molecule were protected from developing amoebic liver abscess after intrahepatic challenge with virulent E. histolytica trophozoites. In contrast, preimmune serum, antiserum to a portion of the 170 kDa adhesin, and antiserum to the trpE fusion partner of SREHP did not protect SCID mice from amoebic liver abscess. Our study demonstrates that antibodies to a recombinant version of the amoebic SREHP molecule can protect against amoebic liver abscess, and suggest the recombinant SREHP molecule should be considered as a possible vaccine candidate to prevent amoebic liver abscess.

Bacterial liver abscess in children.

From November 1987, 136 children with bacterial liver abscess were encountered. There were 97 males and 39 females and the age ranged from 1-15 years (mean = 8.42 years). The clinical signs and symptoms of liver abscess were confirmed by radiography, ultrasonography, percutaneous transhepatic drainage (PTHD) and radioisotope scanning. 103 children had solitary abscess and the remaining 33 children, multiple abscesses. Of the children with multiple abscesses, 23 had abscesses confined to one lobe of the liver and 10 had involvement of both lobes of the liver. 86 children had culture of liver abscesses done and only 63 (73.2%) yielded positive culture. Staphylococcus aureus and Escherichia coli were the commonest organisms cultured from liver abscesses. 72 cases had drainage of liver abscesses, one of them ended up with hepatic artery ligation. A further 15 cases treated by PTHD survived. Of the remaining 49 cases who had antibiotic therapy, 2 died of septicemia, giving a mortality rate of 1.47%. 36.3% of children with liver abscesses responded to antibiotic therapy. The indication and method for surgical management are discussed. Percutaneous transhepatic drainage (PTHD) of liver abscesses, under the guidance of ultrasonography is found to be safe and effective.

Amebic liver abscess complicated with cardiac tamponade and mediastinal abscess.

Amebic pericarditis is an extremely rare complication of liver abscess and an uncommon etiology of sterile pericardial effusion with cardiac tamponade. The association of mediastinal abscess in this clinical setting has not been reported in the literature. Herein, we describe a case of amebic liver abscess complicated with mediastinal abscess and amebic pericarditis with cardiac tamponade. A 44-year-old man was admitted to our hospital because of shortness of breath for the previous 2 days. Cardiac tamponade was diagnosed and emergency pericardiectomy was performed. Chocolate-like pus was found in the pericardial sac and mediastinal space during surgery. Abdominal computed tomography revealed an ill-defined hypodense lesion over the left lobe of the liver, suggesting a liver abscess. Amebic liver abscess and pericarditis were diagnosed on the basis of a high serum titer of amebic antibodies on hemagglutination test. The patient was treated with metronidazole for 2 weeks and discharged in good condition. This case should alert clinicians to the possibility of amebic pericarditis in patients with cardiac tamponade associated with chocolate-like sterile pus in the pericardium and mediastinum. To establish the diagnosis of amebic pericarditis, one should investigate the presence of a liver abscess, a high serum titer of amebic hemagglutination antibodies, and the presence of Entamoeba histolytica trophozoites in the pericardium or pericardial aspirate.

Case report: amoebic liver abscess complicated by a hepatoduodenal fistula.

Amoebic liver abscess (ALA) is a common extra-intestinal presentation of amoebiasis caused by Entamoeba histolytica. The liver abscess may be complicated by rupture into adjacent structures. Common organs involved include thorax, peritoneum and pericardium. Rupture into the gastrointestinal tract is extremely rare. We report a patient who developed a hepatoduodenal fistula complicating an amoebic liver abscess. Suspicions were raised on finding air in the liver abscess on ultrasound scanning. Diagnosis was confirmed on a water-soluble (Gastrografin) swallow (Fig. 1 a,b). Complications of ALA are associated with a high morbidity and mortality and early diagnosis is important. To our knowledge only one previous case of a hepatoduodenal fistula complicating an ALA with radiological confirmation has been reported.

Mal-positioned umbilical venous catheter causing liver abscess in a preterm infant.

Neonatal liver abscess is uncommon, carries a high mortality and is difficult to diagnose. We report an unusual case of liver abscess in a preterm infant presenting with abdominal distension and suspected gastrointestinal perforation, rather than the more usual features of fever, hepatomegaly, abdominal tenderness, right-sided pleural effusion, and leukocytosis. We discuss current treatments for neonatal liver abscess and argue that in view of the high mortality and difficulty in diagnosis, prevention should be the primary objective. We believe that mal-positioning the umbilical venous catheter in the liver substantially increases the life-threatening risk of this complication, and advocate extreme care in the placement and use of these catheters.
