Decreased adenosine deaminase activity in peripheral lymphocytes of patients suffering from amebic liver abscess.

Amebic liver abscess (ALA) is associated with a state of transient suppression of cell-mediated immunity (CMI). T4 helper-inducer cell number is reported to be reduced. However, little is known of the reason for such reduction. Adenosine deaminase (ADA), an enzyme of salvage pathway in purine metabolism, is reported to be essential for the normal growth, differentiation and proliferation of T-lymphoid cells. In a pilot study we estimated the ADA levels in the peripheral lymphocytes of ALA patients. It was observed that the mean enzyme level in patients was 223.98 +/- 51.81 as against 405 +/- 38.12 in controls. The significantly low levels (p < 0.05) of enzyme in patients' lymphocytes may possibly explain the reduction of T4 helper-inducer cells reported in these cases. This parameter, if further evaluated, can serve as a differentiation marker between helper and suppressor T-cell subsets.

Sequential intravenous/oral antibiotic vs. continuous intravenous antibiotic in the treatment of pyogenic liver abscess.

AIM: Pyogenic liver abscesses result in substantial morbidity and mortality. Antimicrobial regimens using sequential intravenous/oral therapy may reduce the length of hospital stay. In this retrospective analysis, the efficacy of continuous intravenous antibiotic therapy (group I) vs. sequential intravenous/oral antibiotic therapy (group II) was studied in patients with pyogenic liver abscess. METHODS: One hundred and twelve consecutive patients (55 in group I and 57 in group II) with pyogenic liver abscess were analysed. Clinical response, length of hospital stay and relapse rates were examined. RESULTS: Group II had a significantly shorter duration of intravenous antibiotic treatment (3.2 weeks vs. 5.9 weeks, P < 0.01) and a shorter length of hospital stay (28 days vs. 42 days, P < 0.01) when compared to group I. Oral antibiotics were prescribed for a median duration of 2.9 weeks in group II after discharge. No relapse occurred within 6 weeks after the completion of treatment in both groups. The cost of therapy was significantly lower in group II than in group I by 33%. CONCLUSIONS: A sequential intravenous/oral antibiotic regime is a safe and effective treatment for pyogenic liver abscess. This reduces the cost of therapy and the length of hospital stay.

[Therapeutic options in the treatment of pyogenic liver abscess].

BACKGROUND/AIMS: Pyogenic liver abscess is a rare and life-threatening disease. Our aim is to discuss the aetiology and problems of diagnosis and treatment of this disease, based on our own clinical experience. We present and compare different therapeutic options, i. e. ultrasound-guided percutaneous abscess drainage, CT-guided drainage and open surgical drainage. PATIENTS/METHODS: In a time period of 8 years, 62 patients with pyogenic liver abscesses were treated. The therapeutic procedure used most frequently was ultrasound-guided percutaneous abscess drainage in 41 patients, followed by CT-guided drainage in 13 cases. 8 patients were primarily treated with surgical drainage or liver resection, respectively. RESULTS: With an overall mortality of 9.6 % we achieved an encouraging result. The comparison of mortality between groups treated with ultrasound-guided percutaneous abscess drainage (7.3 %) and CT-guided drainage (7.7 %) revealed no significant prognostic difference. The comparison of local complications and drainage failure between ultrasound-guided percutaneous abscess drainage (2.4 %) and CT-guided drainage (15.4 %), however, showed better results for the ultrasound-guided interventions (1/41 vs. 2/13 patients). Two patients undergoing open surgical drainage died due to an advanced septic shock syndrome. CONCLUSIONS: Our study suggests that ultrasound duplex imaging with percutaneous abscess drainage is a reliable and effective approach for the treatment of pyogenic liver abscess. Based on other studies in the literature and our own results we developed a diagnostic and therapeutic algorithm for the treatment of liver abscesses.

[Percutaneous drainage treatment of primary liver abscesses].

28 primary liver abscesses, including 9 amoebic abscesses, in 24 patients were drained percutaneously. Indication for drainage in amoebic abscesses was imminent rupture and clinical symptoms as pleural effusion, lung atelectasis and pain. 95% of the primary abscesses were cured by percutaneous drainage and systemic antibiotic treatment. There was one recurrence of abscess, which was managed surgically. Reasons for drainage failure were: tumour necrosis and tumour perforation with secondary liver abscess.

Serum ferritin in Nigerian patients with amoebic liver abscess and other tropical infections with liver involvement.

Serum ferritin was measured by immunoradiometric assay in 46 Nigerian patients with amoebic liver abscess and other tropical infections involving the liver, and the values were compared with those in 23 control subjects. Serum ferritin was markedly elevated in 100% of the patients with amoebic liver abscess, acute viral hepatitis and liver tuberculosis. Elevated values were observed in about 77% of patients with cirrhosis, 80% of malaria patients, and only about 30% of patients with early infection of schistosomiasis mansoni. The results support previous data indicating that significant changes in serum ferritin occur in acute and chronic liver disease. Assay of serum ferritin may be a useful complimentary liver function test for the diagnosis and monitoring the treatment provided in amoebic liver abscess.

Haemophilus parainfluenzae and Fusobacterium necrophorum liver abscess: a case report.

Liver abscess is a potentially life-threatening disease. The clinical features of pyogenic liver abscess are variable and probably correlate with a variety of pathogenic microorganisms and underlying diseases that may be involved. The most common pathogen of liver abscess in Taiwan is Klebsiella pneumoniae. Diabetes mellitus and hepatobiliary calculus are major diseases associated with liver abscess. Haemophilus parainfluenzae is a commensal of the upper respiratory tract, but is an uncommon isolate in liver abscess. We describe a 44-year-old man with liver abscess caused by mixed H. parainfluenzae and Fusobacterium necrophorum infection. He received percutaneous liver abscess drainage and intravenous antibiotic therapy for 3 weeks and fully recovered. No recurrence occurred during the follow-up period of 4 months.

Candida (Torulopsis glabrata) liver abscesses eight years after orthotopic liver transplantation.

The authors report the case of a 48-year-old man in whom candida (Torulopsis glabrata) liver abscesses developed 8 years after liver transplantation. After a week of fever, computed tomography and Doppler ultrasonography showed several fluid-filled loculations in the left lobe of the liver and hepatic arterial stenosis. Aspirates from the abscesses contained T. glabrata organisms. This complication probably developed because hepatic arterial stenosis resulted in bile infarcts (bilomas), which were contaminated via the biliary tract with candida from the biliary-enteric anastomosis. Catheter drainage and administration of amphotericin B for 10 weeks permitted successful retransplantation. T. glabrata liver abscesses, a life threatening complication that can occur long after liver transplantation, can be successfully managed by aggressive medical treatment followed by retransplantation.

Sonographic appearances and percutaneous management of primary tuberculous liver abscess.

Primary tuberculous liver abscesses are rare. We report on 3 patients who presented with a nonresolving abscess in the liver. Clinical presentation and sonographic findings in each case were nonspecific. A diagnosis of tuberculosis was established with microbiologic examination of pus in 2 cases and examination of an excised abscess wall in 1 case. Needle aspiration (1 patient) and short-term (72 hours) catheter drainage (1 patient) were unsuccessful, and surgical excision was required in these patients. In the third patient, continuous catheter drainage over 18 days resulted in cure, indicating that long-term catheter drainage with antituberculous chemotherapy may be a viable alternative to surgery in the management of primary tuberculous liver abscess.

Percutaneous aspiration versus open drainage of liver abscess in children.

Liver abscess, though a very grave problem, is rarely seen in infancy and childhood. Affected children are usually immunocompromised and are of poor socioeconomic status. Although liver abscess due to wandering ascarids is rare outside, it is common complication among children of Kashmir. Usual site of abscess is the right lobe of the liver and USG and CT of the abdomen are the main tools of diagnosis. The study was conducted over a period of 10 years from January 1991 to December 2000 and total of 129 cases were studied in the age group of 0-14 years. Diagnosis was made by a detailed clinical examination together with USG and CT of the abdomen. Out of 129 cases, 49 were treated with antibiotics alone, 55 cases were taken for open drainage, and 27 cases were taken for percutaneous aspiration under USG guidance. Percutaneous aspiration failed in five patients who were later taken for open drainage. Open method was found still to be the best modality of management, although percutaneous aspiration is safe and effective but needs lot of expertise.

Liver abscess in patients with cirrhosis of the liver: a 12-year experience.

PURPOSE: Liver abscess is rare in patients with cirrhosis of the liver. The aim of this retrospective study was to investigate the incidence, clinical presentation, causal pathogens, and outcome of liver abscess in cirrhotic patients. METHODS: We collected 21 liver abscess specimens (from 14 male patients and 7 female patients; Child A: B: C, 4: 7: 10) from 22,731 admissions of 6450 cirrhotic patients, from 1986 through 1998. RESULTS: The common clinical symptoms and signs included fever, chills, and abdominal tenderness. The major predisposing factors were biliary tract disease (52%) and diabetes mellitus (48%). The diagnosis rate with abdominal ultrasonography was 79%. Gram-negative aerobes were the predominant pathogens (Klebsiella pneumoniae, 66.7%; Escherichia coli, 23.8%), and occurred in 80% and 69% of blood and pus cultures, respectively, while 38% of cases showed polymicrobial pathogens. The location of the abscess was predominantly in the right lobe (71.4%), and 47.6% of patients had multiple abscesses. Six patients died (all with Child C cirrhosis). The overall mortality rate was 28.6% (6/21). CONCLUSIONS: The incidence of liver abscess in the cirrhotic patients was low, at 0.09% (21/22,731 admissions). The clinical presentations and pathogens were not different from those in noncirrhotic patients, except that in our cirrhotic patients, there was no significant difference in mortality between those with monomicrobial and those with polymicrobial abscess: nor was there a significant difference in mortality between those with single and those with multiple abscesses. The Child C patients were the high-risk group.

Clinical course, treatment, and multivariate analysis of risk factors for pyogenic liver abscess.

BACKGROUND: Pyogenic liver abscess is a threatening condition. The purpose of this study was to audit the clinical behavior and to analyze the risk factors. METHODS: One hundred and thirty-three patients treated in five hospitals during the years 1985 to 1997 were studied. By univariate and multivariate analysis we tried to identify any risk factor associated with complicated clinical course and complicated-related clinical course, and with hospital mortality. RESULTS: Sixty-three patients (47%) were subjected to a percutaneous drainage, 45 (34%) were treated by open surgical drainage, and the remaining 25 cases (19%) received antibiotic therapy alone. Prognostic variables for a complicated clinical course were the presence of shock, low hemoglobin level, elevated prothrombin time, and polymicrobial infection. Shock, distress, low hemoglobin level, increased creatinine, and positive blood culture were significant predictors of a complicated-related clinical course. Concerning mortality, a biliary origin, shock, multiple abscesses, low hemoglobin level, and high concentration of blood urea nitrogen were independent predictors. CONCLUSIONS: Treatment of pyogenic liver abscesses should be tailored to each patient, however, the majority of them can be successfully treated with antibiotics and percutaneous methods. Those with signs of organ failure or septicemia should preferably be managed in the intensive care unit.

Case report: Clostridium septicum infection presenting as liver abscess in a case of choriocarcinoma with liver metastasis.

Clostridium septicum is an anaerobic, gram-positive bacillus. Infection with this organism has a known association with malignant diseases, especially colon and haematological cancers. Clostridium septicum is rarely found to be a pathogen of liver abscess. Herein, we report the case of a female choriocarcinoma patient with liver metastasis in which C. septicum infection presented as a gas-forming liver abscess. This case and previous reports indicate that once C. septicum is identified as a pathogen in liver abscess, metastatic liver tumours should be highly suspected.

Genomic prediction and genome-wide association study for liver abscesses in crossbred beef cattle.

Liver abscesses are a concern in feedlot cattle, and little is known about the role of genetics in their development. This study aimed to estimate genetic parameters and to identify single-nucleotide polymorphisms (SNPs) associated with liver abscesses. Crossbred cattle representing 18 breeds in the U.S. Meat Animal Research Center Germplasm Evaluation Program were phenotyped for liver abscesses at slaughter (n&#x2005;=&#x2005;9,044). Seventeen percent of cattle had liver abscesses. These cattle had genotypes that were imputed to sequence variant genotypes. After filtering and quality control, 340,723 SNPs were used in the analysis. Liver abscess prevalence was modeled with a single-step genomic best linear unbiased prediction (ssGBLUP) threshold model using a Bayesian framework. The model included contemporary group (sex, treatment group, and slaughter date), additive genomic, and residual effects. Genomic heritability was 0.039 (95% highest posterior density&#x2005;=&#x2005;0.005, 0.081), which was very small. To assess prediction quality, a 5-fold random cross-validation structure was used. Method Linear Regression was used to assess accuracy, bias, and dispersion by comparing estimated breeding values (EBV) from full and reduced analyses. Cross-validation metrics showed EBV based on genotypes had 0.05 reliability (SD&#x2005;<&#x2005;0.01) with no bias relative to EBV based on genotypes and phenotypes. For the genome-wide association study, SNP effects were back calculated from the EBV solutions from ssGBLUP. No SNPs were associated with liver abscesses at a Benjamini-Hochberg adjusted 0.05 significance level. Although a large dataset was used, this result was because of the low genomic heritability and imprecise EBV used to calculate SNP effects. Based on these results, environmental factors contribute to most of the variation in liver abscesses. Genetic selection to reduce liver abscesses would be slow because of the low genomic heritability, measurement late in life, and inability to measure breeding animals. A faster approach would be finding additional environmental interventions that maintain animal performance.
