Detection of pathogenic Entamoeba histolytica DNA in liver abscess fluid by polymerase chain reaction.

A sensitive method for detection of pathogenic Entamoeba histolytica DNA in drained fluids from liver abscess patients, using the polymerase chain reaction (PCR), has been developed. The PCR employs oligonucleotide primers specific for the gene encoding the 30 kDa molecule of pathogenic E. histolytica. Liver abscess fluids (19 samples), from 14 patients with a presumptive amebic liver abscess, were examined microscopically and by the PCR method. Only two of the 19 samples were positive microscopically, whereas all 19 samples tested positive by PCR. This technique can be used to confirm the diagnosis of amebic liver abscess.

Pyogenic liver abscesses in children.

Five children with pyogenic liver abscess were admitted to Institute of Child Health, Kabul during the period 1978 to 1980. All patients were males, and their ages ranged from 4 to 10 years. The clinical picture was characterized by fever, upper abdominal pain, enlarged tender liver with raised right dome of the diaphragm. The abscesses were located in the right lobe of liver in all cases, and they were solitary in three cases. Staphylococcus aureus was the etiologic agent in four cases and Escherichia coli in one. Open surgical drainage coupled with prompt parenteral antibiotic therapy in all cases seem to have favorably influenced the outcome. With a high index of suspicion pyogenic liver abscess in children can be diagnosed clinically without the aid of hepatic radionuclide scanning.

Morganella morganii causing solitary liver abscess complicated by pyopericardium and left pleural effusion in a nondiabetic patient.

Morganella morganii is a rare cause of solitary liver abscess in Taiwan. The complication of pyopericardium and pleural effusion in nondiabetic patient with solitary liver abscess are also rare. We present a case of a 48-year-old nondiabetic woman who experienced with epigastric discomfort 1 month prior to admission. Chills and fever developed 2 weeks before admission. Physical examination on admission revealed engorgement of the jugular vein over the right neck, precordial friction rubs, and tenderness over the right upper quadrant of abdomen. Chest film showed mild cardiomegaly and left pleural effusion. Computed tomography of the abdomen showed liver abscess, left hepatic lobe, pyopericardium, and left pleural effusion. M. morganii was isolated from 2 sets of blood cultures, one set of hepatic pus culture, and one set of pericardial pus culture. After pigtail drainage of liver abscess, pyopericardium for 12 days, and ceftriaxone intravenous administration for 19 days, the patient was discharged in stable condition.

Pyogenic liver abscess: changing epidemiology and prognosis.

We reviewed the clinical features, methods of diagnosis, and outcome of 31 patients with pyogenic liver abscess seen at a private community hospital between 1973 and 1980. Two patient groups emerged. Group 1 consisted of 25 patients who had classical signs and symptoms of primary liver abscess. Group 2 consisted of six patients, most with underlying malignancy, in whom liver abscess(es) occurred as part of a septicemic process involving multiple other sites. The mortality was 0% in group 1 and 100% in group 2. Further analysis of the patients in group 1 revealed that (1) in contrast to findings of older studies, pyogenic liver abscess in now largely a disease of older adults who often have no identifiable predisposing process; (2) newer noninvasive imaging techniques greatly facilitate a firm diagnosis; and (3) the prognosis for such patients has become remarkably good, perhaps because of earlier diagnosis.

A case of hemolytic uremic syndrome associated with emphysematous cholecystitis and a liver abscess.

Hemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. Most cases of HUS are characterized by a prodromal phase of diarrhea and melena, and affect mainly children. Here we report a unique case of adult-onset HUS that was associated with emphysematous cholecystitis and a liver abscess. The patient did not suffer from diarrhea or melena on admission, but abdominal CT scans revealed emphysematous cholecystitis and a liver abscess. Cholecystectomy was performed and the liver abscess was drained. Cultures of the bile and liver abscess contents were negative, but the serum samples had antibodies against Escherichia coli (E. coli) O157. The patient was anuric for 14 days, and underwent hemodialysis that was repeated 15 times and plasma exchanges 6 times. She recovered from acute renal failure but with inadequate urinary concentrating ability as a sequela. Histopathological examination of renal biopsy specimens on the 83rd hospital day revealed almost normal glomeruli and patchy atrophy of tubules with an increase of interstitium. This is a very rare case of HUS associated with emphysematous cholecystitis and a liver abscess successfully treated with aggressive supportive care. It is possible that an infection with verotoxin-producing E. coli O157 caused the disease.

Endoscopic biliary drainage in patients with amebic liver abscess and biliary communication.

BACKGROUND: Percutaneous drainage or surgery is required when amebic liver abscess (ALA) fails to respond to medical management. In some of these patients, non-response may be due to communication of ALA with the biliary tree. This report describes our experience with the use of endoscopic biliary draining in such patients. METHODS: Medical records of patients with ALA undergoing either needle aspiration or percutaneous pigtail drainage were retrieved; the indications for drainage were: abscess volume exceeding 250 mL, a thin rim of tissue (< 1 cm thick) around the abscess, systemic toxic features and failure to improve on medical treatment. Patients with abscess drain output >25 mL/day persisting for 2 weeks or presence of bile in the drain fluid underwent endoscopic biliary drainage. RESULTS: A total of 115 patients with ALA underwent percutaneous treatment. None of the 25 patients with needle aspiration needed any further treatment. Of the 90 who underwent catheter drainage, the catheter could be removed within one week in 77 patients; the remaining 13 patients (median age 42 years, range 24-65; all men) had an abscess-biliary communication. In them, the median catheter output was 88 mL/day (range 45-347) and 54 mL/day (28-177) at 2 days and 2 weeks after catheter placement. The drain fluid contained bile in all 13 patients and in addition contained pus in 10 patients. Eleven patients had a solitary abscess and two had multiple abscesses. Cholangiogram showed biliary communication in all 13 patients. All patients were treated with placement of 10F biliary endoprosthesis or 10F nasobiliary drain. Pigtail catheter was removed within 1 week in 11 of 13 patients. CONCLUSION: In patients with amebic liver abscess communicating with the biliary tree, biliary stenting may hasten clinical recovery and allow early removal of liver abscess catheter drain.

Risk factors for endogenous endophthalmitis secondary to Klebsiella pneumoniae liver abscess.

BACKGROUND: To identify the risk factors for endogenous endophthalmitis secondary to Klebsiella pneumoniae (KP) liver abscess. METHODS: Retrospective chart review of 200 patients with KP liver abscess from 1990 to 2000 was performed. Data variables included age, sex, past history, systemic condition, initial and final visual acuity, slit lamp biomicroscopy, intraocular pressure, fundus, course and treatment. RESULTS: Extrahepatic metastasis developed in 44 patients, including 18 cases (23 eyes) of endophthalmitis. Seventeen eyes had final vision less than counting fingers. Diabetes had significant association with the development of extrahepatic metastasis (p = 0.045) and the poor visual outcome of endophthalmitis (p = 0.022), whereas, neither the initial vision nor vitrectomy was significantly related to the outcome of endophthalmitis. CONCLUSIONS: The visual prognosis of endogenous endophthalmitis secondary to KP liver abscess is generally poor, and diabetes might be a significant risk factor for the poor visual outcome. Even when the initial vision is as bad as light perception only, some eyes can be saved. Both internists and ophthalmologists should be alert enough to detect and treat these patients early.

A case of hepatocolic fistula after percutaneous drainage for a gas-containing pyogenic liver abscess.

We describe a rare case of gas-containing pyogenic liver abscess which penetrated the adjacent colon, forming a hepatocolic fistula, after percutaneous transhepatic abscess drainage (PTAD) had been performed. To the best of our knowledge, this is the first report of hepatocolic fistula associated with a gas-forming liver abscess in a diabetic patient, with radiological and surgical confirmation of the fistula.

Comparison of pyogenic liver abscesses of biliary and cryptogenic origin. An eight-year analysis in a University Hospital.

OBJECTIVES: The aim of this study is to delineate the clinical features of pyogenic liver abscesses of biliary and cryptogenic origin, and to compare the differences in outcome of patients between the two groups. METHODS: We studied 86 patients, aged 19 years or older, with pyogenic liver abscess admitted to Chung Shan Medical University Hospital, Taichung, Taiwan, between January 1996 and December 2003. The demographic data and medical information of the patients were reviewed and recorded. Of the 86 patients, 34 were classified into the biliary group and 52 were classified into the cryptogenic group. RESULTS: Patients with pyogenic liver abscesses of biliary origin had a higher frequency of underlying malignancy and Murphy's sign compared to those with pyogenic liver abscesses of cryptogenic origin. With respect to specific pathogens, Escherichia coli were more prevalent in the biliary group while Klebsiella pneumoniae were more prevalent in the cryptogenic group. Anaerobic isolates were less frequently cultured in the cryptogenic group than in the biliary group. After adjustment for age, sex, and the duration of symptoms before admission, there was no difference in mortality between both groups (biliary vs cryptogenic: 15% vs 8%; adjusted OR, 1.43; 95% CI, 0.24-8.25; p = 0.899). After adjustment for confounders, patients in the biliary group had higher frequencies of time to defervesce >1 week after admission (68% vs 40%; adjusted OR, 3.05; 95% CI, 1.09-9.04, p = 0.030) and hospital stay >3 weeks (47% vs 15%; adjusted OR, 4.34; 95% CI, 1.45-13.91; p = 0.007) than those in the cryptogenic group. CONCLUSIONS: This report highlights that pyogenic liver abscesses of cryptogenic origin had a benign clinical response, which was associated with shorter duration of hospitalisation and time to defervesce after admission, compared to those of biliary origin.

Pyogenic liver abscess: is drainage always possible?

The treatment of pyogenic liver abscess generally involves antibiotic therapy and radiological percutaneous drainage or aspiration. Surgical drainage is rarely advisable. We report a case of multiloculated liver abscess that was not suitable for either percutaneous drainage or open surgical drainage. The only successful approach was a left hepatectomy.

[Clinical analysis of 36 cases with amebic liver abscess].

OBJECTIVE: To investigate the clinical features of amebic liver abscess, the causes of misdignosis and the effect of medical and surgical therapy on patient's prognosis. METHODS: The clinical features of 36 patients with amebic liver abscess admitted from 1982 to 1997 in our hospital were retrospectively reviewed. RESULTS: The major clinical manifestations were: abdominal pain (86.1%), fever (86.1%), hepatomegaly with tenderness (83.3%) and right intercostal tenderness (58.3%). Leukocytosis was observed in 61.1%, and increased of ESR in 88.5% (23/28). Serologies against Entamoeba histolytica were noted in 92.6%. Ultrasonography showed single lesions in 75% and right-lobe involvement in 75%. All patients were treated with metronidazole and 27 patients received treatment with needle aspiration or draining at the same time. After treatment, 10 patients were cured, 25 patients were improved significantly and effective rate was 97.2%. One patient died of hepatic failure. CONCLUSION: Medical therapy alone was excellent for small abscesses, while percutaneous needle aspiration or draining was a successful approach in patients with large abscesses.

Eikenella corrodens liver abscess complicated by endophthalmitis.

A 64-year-old man who presented with sudden, unilateral loss of vision was found to have endophthalmitis associated with a pyogenic liver abscess. The patient was successfully managed with subtotal vitrectomy and percutaneous drainage of the liver abscess. Eikenella corrodens was cultured from the blood and the pus drained from the liver abscess. This is the first reported case of Eikenella corrodens liver abscess complicated by endophthalmitis.

[Results of surgical treatment of liver abscess, with special emphasis of percutaneous puncture and drainage].

Authors present 5 cases of liver abscess treated with US or CT guided percutaneous puncture and/or drainage performed in cooperation of the 2nd Surgical Department and the Radiological Department of the University of Debrecen. They analyse the indications and results of this method. They also include the results of twelve liver abscesses treated surgically. For one or a small number of liver abscesses (Bigger than 5 cm) they prefer percutaneous drainage combined with systematic antibiotic treatment if the condition is not complicated by other surgical diseases, and if the abscesses are accessible for radiological intervention. All patients recovered without recurrence during a one-year follow-up period. The main advantages of this method are smaller trauma and fewer complications.

Detection of circulating antigen in amoebic liver abscess by counter-current immunoelectrophoresis.

Fifty serum samples from patients with amoebic liver abscess and 50 from subjects who had not suffered from the disease (25 from patients with other, chiefly parasitic, infections and 25 from healthy blood donors, staff or students) were tested for circulating amoebic antigen by counter-current immuno-electrophoresis (CIEP). Amoebic antigen was detected in 38 sera (76%) from cases of amoebic liver abscess, but in none of the other sera. Although CIEP is only moderately sensitive, the high specificity suggests that this simple test may be useful in the diagnosis of amoebic liver abscess.

Solitary liver abscess: a continuing medicosurgical problem.

The management problems of 22 patients with solitary liver abscess are reviewed. To achieve earlier diagnosis, and reduce the high mortality rate of this condition (32% in this series), clinicians need to change their data base of the clinical presentation and also to incorporate liver imaging as part of the routine investigation of a patient with pyrexia of uncertain origin. The problems associated with operative diagnosis, and with methods of surgical drainage are discussed. The need for careful bacteriological cultures is emphasized, and the use of the most appropriate antibiotics is described. While in many cases the cause of the liver abscess remains unknown, in Australia the possibility of the abscess being amoebic or an infected hydatid cyst should be kept in mind.

[Liver abscess as a complication of TAE--risk factors and prevention].

Transcatheter hepatic arterial embolization for not only hepatocellular carcinoma but metastatic liver cancers is nowadays prevalent. Gall bladder infarction, cholangitis, peptic ulcers, pancreatitis, and aneurysm are reported as complications of it. But the liver abscess following it is rare. We reviewed three cases of liver abscesses after transcatheter hepatic arterial embolization. Biliary tract congestion and inflammation, and iatrogenic contaminations are supposed to major factors that caused liver abscesses. We think we should refrain from the embolization until biliary tract disorders are resolved and take care not to contaminate the proceeding materials in addition to mixing antibiotics with embolus.
