Efficacy of empirical Ciprofloxacin or Cefixime plus Metronidazole therapy for the treatment of liver abscess: a randomized control clinical trial. Sci Rep 2024; 14:11430. [PMID: 38769330 PMCID: PMC11106291 DOI: 10.1038/s41598-024-59607-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 04/12/2024] [Indexed: 05/22/2024] Open
Abstract
Liver abscess is a potentially life-threatening medical emergency. Prompt empirical antimicrobial with or without percutaneous aspiration or drainage is therapeutic. The rational for using empirical intravenous broad-spectrum antimicrobials upfront instead of oral Fluoroquinolone or Cephalosporin is contentious. In this double blind randomized control clinical trial 69 participants received Ciprofloxacin (500 mg q 12 hourly) and 71 participants received Cefixime (200 mg q 12 hourly) orally for 2 weeks. Both the group received oral Metronidazole (800 mg q 8 hourly) for 2 weeks and percutaneous drainage or aspiration of the abscess was done as per indication and followed-up for 8 weeks. Out of 140 participants, 89.3% (N = 125) achieved clinical cure, 59 (85.5%) in Ciprofloxacin group and 66 (93%) in Cefixime group (p = 0.154). Mean duration of antimicrobial therapy was 16.2 ± 4.3 days, 15.1 ± 4.5 days in Ciprofloxacin group and 16.0 ± 4.2 days in Cefixime group (p = 0.223). Total 15 (10.7%) participants had treatment failure, 10 (14.5%) in Ciprofloxacin group and 5 (7.0%) in Cefixime group (p = 0.154). The most common reason for treatment failure was need of prolong (> 4 weeks) antimicrobial therapy due to persistent hepatic collection requiring drainage, which was significantly (p = 0.036) higher in Ciprofloxacin (14.5%, N = 10) group, compared to the Cefixime (4.2%, N = 3) group. In conclusion, both, the Ciprofloxacin or Cefixime plus Metronidazole for duration of 2-3 weeks were efficacious as empirical oral antimicrobial regimen along with prompt percutaneous drainage or aspiration for the treatment of uncomplicated liver abscess with similar efficacy. Oral Cefixime was better than Ciprofloxacin in term of lesser chance of treatment failure due to persistent collection which is required to be investigated further in larger clinical trial.Trial registration: clinicaltrials.gov PRS ID: NCT03969758, 31/05/2019.

Amebic liver abscess: An update. World J Hepatol 2024; 16:316-330. [PMID: 38577528 PMCID: PMC10989314 DOI: 10.4254/wjh.v16.i3.316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 01/23/2024] [Accepted: 02/21/2024] [Indexed: 03/27/2024] Open
Abstract
Amebic liver abscess (ALA) is still a common problem in the tropical world, where it affects over three-quarters of patients with liver abscess. It is caused by an anaerobic protozoan Entamoeba hystolytica, which primarily colonises the cecum. It is a non-suppurative infection of the liver consisting primarily of dead hepatocytes and cellular debris. People of the male gender, during their reproductive years, are most prone to ALA, and this appears to be due to a poorly mounted immune response linked to serum testosterone levels. ALA is more common in the right lobe of the liver, is strongly associated with alcohol consumption, and can heal without the need for drainage. While majority of ALA patients have an uncomplicated course, a number of complications have been described, including rupture into abdomino-thoracic structures, biliary fistula, vascular thrombosis, bilio-vascular compression, and secondary bacterial infection. Based on clinico-radiological findings, a classification system for ALA has emerged recently, which can assist clinicians in making treatment decisions. Recent research has revealed the role of venous thrombosis-related ischemia in the severity of ALA. Recent years have seen the development and refinement of newer molecular diagnostic techniques that can greatly aid in overcoming the diagnostic challenge in endemic area where serology-based tests have limited accuracy. Metronidazole has been the drug of choice for ALA patients for many years. However, concerns over the resistance and adverse effects necessitate the creation of new, safe, and potent antiamebic medications. Although the indication of the drainage of uncomplicated ALA has become more clear, high-quality randomised trials are still necessary for robust conclusions. Percutaneous drainage appears to be a viable option for patients with ruptured ALA and diffuse peritonitis, for whom surgery represents a significant risk of mortality. With regard to all of the aforementioned issues, this article intends to present an updated review of ALA.

Clinical characteristics, diagnosis, treatment, and outcome of patients with liver abscess due to Aspergillus spp: a systematic review of published cases. BMC Infect Dis 2024; 24:345. [PMID: 38519916 PMCID: PMC10960385 DOI: 10.1186/s12879-024-09226-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 03/14/2024] [Indexed: 03/25/2024] Open
Abstract
BACKGROUND Aspergillus spp liver abscess is a relatively rare entity and thus far no systematic review has been performed examining patients' demographics, clinical manifestations, diagnosis, management, and outcome. METHODS We performed a systematic review of the literature using MEDLINE and LILACS databases. We searched for articles published in the period from January 1990 to December 24, 2022, to identify patients who developed liver abscesses due to Aspergillus spp. RESULTS Our search yielded 21 patients all of whom had invasive aspergillosis confirmed on liver biopsy. Of these patients 81% were adults, and 60% were males. The majority (86%) of patients were immunocompromised and 95% had symptomatic disease at the time of diagnosis. The most common symptoms were fever (79%), abdominal pain (47%), and constitutional symptoms (weight loss, chills, night sweats, fatigue) (38%). Liver enzymes were elevated in 50%, serum galactomannan was positive in 57%, and fungal blood cultures were positive in only 11%. Co-infection with other pathogens preceded development of apsergillosis in one-third of patients, and the majority of the abscesses (43%) were cryptogenic. In the remaining patients with known source, 28% of patients developed liver abscess through dissemination from the lungs, 19% through the portal vein system, and in 10% liver abscess developed through contiguous spread. The most common imaging modality was abdominal computerized tomography done in 86% of patients. Solitary abscess was present in 52% of patients while 48% had multiple abscesses. Inadequate initial empiric therapy was prescribed in 60% of patients and in 44% of patients definite treatment included combination therapy with two or more antifungal agents. Percutaneous drainage of the abscesses was done in 40% of patients, while 20% required liver resection for the treatment of the abscess. Overall mortality was very high at 38%. CONCLUSION Further studies are urgently needed for a better understanding of pathophysiology of liver aspergillosis and for developement of newer blood markers in order to expedite diagnosis and decrease mortality.

Observational Study of Clinical Profiles and Management of Liver Abscess in Hospitalized Patients: A North Indian Tertiary Care Perspective. Cureus 2024; 16:e54401. [PMID: 38505450 PMCID: PMC10950039 DOI: 10.7759/cureus.54401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/17/2024] [Indexed: 03/21/2024] Open
Abstract
Background Liver abscesses are a significant health concern, necessitating prompt diagnosis and appropriate management. Spontaneous liver abscesses are a frequent reason for hospitalizations in India, particularly in the northern part. By analyzing demographics, symptoms, radiological findings, laboratory parameters, and treatment outcomes, this study will contribute valuable insights to enhance the understanding and management of liver abscesses. Aims and objective To evaluate demographic, clinical, laboratory, and radiological parameters and management options in hospitalized patients with liver abscesses at a tertiary care center. Methods This study retrospectively analyzed prospectively collected data from 150 patients diagnosed with liver abscesses who were admitted to our ward for one year. Data on demographic characteristics, clinical presentation, etiology, radiological findings, laboratory investigations, management strategies, and treatment outcomes were collected. Descriptive statistics and relevant statistical tests were employed for data analysis. Results The study population had a mean age of 40.28±12.72 years, with a male preponderance (136 (90.7%)). Amoebic abscesses (94 (62.7%)) were the most common. Hepatomegaly (144 (96%)), fever (140 (93.3%)), abdominal pain (136 (90.7%)), and anorexia (118 (78.7%)) were the most common symptoms. Ultrasonography revealed solitary abscesses (99 (66%)) to be more common than multiple abscesses (24 (16%)), with a predominant location in the right lobe (128 (85.3%)). Laboratory investigations showed leukocytosis in 121 (80.7%), elevated liver enzymes (95 (63.3%) aspartate aminotransferase (AST) and 80 (53.3%) alanine transaminase (ALT)), elevated alkaline phosphatase (ALP) in 133 (88.7%), and low albumin levels (138 (92%)) in a significant proportion of patients. Single-time needle aspiration (95 (63.3%)), percutaneous drain (36 (24%)), and surgical intervention (4 (2.7%)) were the primary treatment modalities. Serum albumin level (p<0.001) and ALP (p<0.001) were significantly low and high, respectively, in patients with hospital stays ≥10 days. Conclusions This study provides insights into patients with liver abscesses' clinical and laboratory parameters and management strategies. The findings highlight the diverse clinical presentation, varied etiologies, and the importance of radiological imaging and laboratory investigations in diagnosis and management. Tailored treatment strategies based on the patient's condition are crucial for optimizing outcomes.

The impact of liver abscess formation on prognosis of patients with malignant liver tumors after transarterial chemoembolization. Front Oncol 2023; 13:1256012. [PMID: 38023156 PMCID: PMC10661366 DOI: 10.3389/fonc.2023.1256012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 10/23/2023] [Indexed: 12/01/2023] Open
Abstract
Purpose Liver abscess is a rare and serious complication after transarterial chemoembolization (TACE) for liver cancer; however, its impact on the prognosis is unclear. This retrospective study examined the outcomes of patients with liver abscess formation following TACE for malignant liver tumors to elucidate the impact of liver abscess formation on the prognosis of these patients. Methods From January 2017 to January 2022, 1,387 patients with malignant tumors underwent 3,341 sessions of TACE at our hospital. Clinical characteristics of patients at baseline and follow-up were examined, including treatment and outcome of liver abscess, tumor response to the TACE leading to liver abscess, and overall survival time. Results Of 1,387 patients, 15 (1.1%) patients with liver abscess complications after TACE resulted in a total of 16 (0.5%) cases of liver abscess after 3,341 TACE sessions (including one patient with two events). After antibiotic or percutaneous catheter drainage (PCD) treatment, all the infections associated with liver abscesses were controlled. In the PCD group, eight patients died before drainage tube removal, one retained the drainage tube until the end of follow-up, and five underwent drainage tube removal; the mean drainage tube removal time was 149.17 ± 134.19 days. The efficacy of TACE leading to liver abscess was evaluated as partial response (18.75%), stable disease (37.5%), and progressive disease (43.75%). Eleven patients died during the follow-up period owing to causes unrelated to infections caused by liver abscesses. The survival rates at 3 months, 6 months, 1 year, and 5 years were 86.7%, 50.9%, 25.5%, and 17%, respectively. Conclusion Patients with liver abscess formation following TACE for malignant liver tumors experienced prolonged drainage tube removal time after PCD; while this condition did not directly cause death, it indirectly contributed to a poor prognosis in these patients.

Profile of Amoebic vs Pyogenic Liver Abscess and Comparison of Demographical, Clinical, and Laboratory Profiles of these Patients From a Tertiary Care Center in Northern India. J Clin Exp Hepatol 2023; 13:1025-1031. [PMID: 37975052 PMCID: PMC10643512 DOI: 10.1016/j.jceh.2023.07.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 07/03/2023] [Indexed: 11/19/2023] Open
Abstract
Background and objective Amoebic liver abscess (ALA) and pyogenic liver abscesses (PLA) are the most common causes of liver abscess in developing and developed countries, respectively. Although incidence of liver abscess is low, but mortality is high amongst the patients due to delayed diagnosis. The study was done to find out the prevalence of amoebic and PLA among patients of liver abscess. The clinical, personal, and demographical details were also evaluated to find out the risk factor(s) associated with ALA and PLA, respectively. Method A retrospective study was conducted to find the prevalence of amoebic and PLA. Clinical, demographic, personal details were evaluated from hospital records. Laboratory parameters such as total leucocyte count, platelets, bilirubin, ESR (Erythrocyte Sedimentation Rate), hemoglobin, glycosylated hemoglobin (HbA1c), alkaline phosphate (ALP), Aspartate aminotransferase (SGOT/AST), Alanine aminotransferase (SGPT/ALT), serum albumin, bilirubin levels, and procalcitonin were recorded. The Ultrasonography (USG) findings regarding the size, location, volume, and number of abscesses were also analyzed. Results Total of 107 patients of liver abscess were evaluated, and 61.6% of patients were of amoebic etiology, and 25.3% were of pyogenic etiology. Males of 20-60 years of age were predominantly affected with right upper quadrant pain and fever as the most common presentations. ALA patients were found to have solitary abscess in the right lobe involving 6th and 7th segments, with decreased hemoglobin, hyperbilirubinemia, elevated ALP and SGOT, with normal SGPT, and addiction to alcohol. PLA patients had increased HbA1c, increased PCT values, low serum albumin levels, and low platelet-to-white blood cell values. The most common bacteria causing PLA was Escherichia coli (n = 8) followed by Enterobacter cloacae (n = 5). Mortality was seen in 6 patients. Conclusion Liver abscess is found to have relatively high mortality and morbidity. Therefore, early diagnosis is the only method to prevent mortality and morbidity in these patients. Since the presentation is very nonspecific, evaluation of certain risk factors and laboratory parameters can aid in the diagnosis.

Abstract
A liver abscess is a collection of purulent fluid in the liver parenchyma caused by a variety of etiological organisms such as bacteria, protozoa, and in rare occasions fungi. Mycobacterium tuberculosis (MTB) is a frequent and widespread infection in underdeveloped nations such as India, which can manifest in many ways. Tuberculosis mostly affects the lungs, although it can also affect any organ in the body. We are reporting a case of liver abscess caused by MTB infection in order to raise general awareness among physicians about the importance of suspecting and ruling out tuberculosis as a cause of liver abscess. To the best of our knowledge, there have been very few such cases reported from India/the rest of the world.

Abstract
An 18-year-old male developed a huge liver abscess with severe anemia over the course of 2 weeks. Abdominal contrast enhanced computed tomography showed ruptured huge liver abscess in the right liver lobe with signs of active hemorrhage (contrast extravasation). Serology examination confirmed amoeba as the suspected pathogen of cause. Angiography was performed followed by transcatheter arterial embolization to localize and control the hemorrhage. Embolization using a combination of polyvinyl alcohol and gelfoam successfully controlled the active hemorrhage. Exploratory laparotomy was performed to evacuate and debride the huge abscess. Metronidazole was given and showed good results. Huge liver abscess size is a predictor of conservative management failure and requires a gradual step-up intervention. The purpose of this paper is to explain the importance of imaging in detecting liver abscess and active hemorrhage along with the role of interventional radiology in this case.

Pyogenic liver abscesses in liver transplant recipients versus non-transplant population. Outcome and risk factors of patient survival. Clin Transplant 2023:e14966. [PMID: 36943872 DOI: 10.1111/ctr.14966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 02/10/2023] [Accepted: 03/05/2023] [Indexed: 03/23/2023]
Abstract
Pyogenic liver abscess (PLA) is a life-threatening infection in both liver transplant (LT) and non-LT patients. Several risk factors, such as benign and malignant hepatopancreatobiliary diseases and colorectal tumors have been associated with PLA in the non-LT population, and hepatic artery stricture/thrombosis, biliary stricture, and hepaticojejunostomy in the LT patients. The objective of this study is to compare the outcomes of patients with PLA in LT and non-LT patients and to determine the risk factors associated with patient survival. From January 2000 to November 2020, a total of 296 adult patients were diagnosed of PLA in our institution, of whom 26 patients had previously undergone liver transplantation (LTA group), whereas 263 patients corresponded to the non-LTA population. Seven patients with PLA who had undergone previous kidney transplantation were excluded from this retrospective study. Twenty-six patients out of 1503 LT developed PLA (incidence of 1.7%). Median age was significantly higher in non-LTA patients (p = .001). No significant differences were observed in therapy. PLA recurrence was significantly higher in LTA than in non-LTA (34.6% vs. 14.8%; p = .008). In-hospital mortality was greater in the LT group than in the non-LT group (19.2% vs. 9.1% p = .10) and was identified in multivariable analysis as a risk factor for mortality (p = .027). Mortality rate during follow-up did not show significant differences between the groups: 34.6% in LTA patients versus 26.2% in non-LTA patients (p = .10). The most common causes of mortality during follow-up were malignancies, Covid-19 infection, and neurologic disease. 1-, 3-, and 5-year actuarial patient survival rates were 87.0%, 64.1%, and 50.4%, respectively, in patients of LTA group, and 84.5%, 66.5%, and 51.0%, respectively, in patients with liver abscesses in non-LTA population (p = .53). In conclusion, LT was a risk factor for in hospital mortality, but not during long-term follow-up.

Risk factors indicating the need for surgical therapy in patients with pyogenic liver abscesses. Langenbecks Arch Surg 2023; 408:97. [PMID: 36808482 PMCID: PMC9942623 DOI: 10.1007/s00423-023-02837-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Accepted: 02/13/2023] [Indexed: 02/23/2023]
Abstract
BACKGROUND Percutaneous drainage (PD) and antibiotics are the therapy of choice (non-surgical therapy [non-ST]) for pyogenic liver abscesses (PLA), reserving surgical therapy (ST) for PD failure. The aim of this retrospective study was to identify risk factors that indicate the need for ST. METHODS We reviewed the medical charts of all of our institution's adult patients with a diagnosis of PLA between January 2000 and November 2020. A series of 296 patients with PLA was divided into two groups according to the therapy used: ST (n = 41 patients) and non-ST (n = 255). A comparison between groups was performed. RESULTS The overall median age was 68 years. Demographics, clinical history, underlying pathology, and laboratory variables were similar in both groups, except for the duration of PLA symptoms < 10 days and leukocyte count which were significantly higher in the ST group. The in-hospital mortality rate in the ST group was 12.2% vs. 10.2% in the non-ST group (p = 0.783), with biliary sepsis and tumor-related abscesses as the most frequent causes of death. Hospital stay and PLA recurrence were statistically insignificant between groups. One-year actuarial patient survival was 80.2% in the ST group vs. 84.6% in the non-ST (p = 0.625) group. The presence of underlying biliary disease, intra-abdominal tumor, and duration of symptoms for less than 10 days on presentation comprised the risk factors that indicated the need to perform ST. CONCLUSIONS There is little evidence regarding the decision to perform ST, but according to this study, the presence of underlying biliary disease or an intra-abdominal tumor and the duration of PLA symptoms < 10 days upon presentation are risk factors that should sway the surgeons to perform ST instead of PD.

Abstract
In its classic form, amebic liver abscess (ALA) is a mild disease, which responds dramatically to antibiotics and rarely requires drainage. However, the two other forms of the disease, i.e., acute aggressive and chronic indolent usually require drainage. These forms of ALA are frequently reported in endemic areas. The acute aggressive disease is particularly associated with serious complications, such as ruptures, secondary infections, and biliary communications. Laboratory parameters are deranged, with signs of organ failure often present. This form of disease is also associated with a high mortality rate, and early drainage is often required to control the disease severity. In the chronic form, the disease is characterized by low-grade symptoms, mainly pain in the right upper quadrant. Ultrasound and computed tomography (CT) play an important role not only in the diagnosis but also in the assessment of disease severity and identification of the associated complications. Recently, it has been shown that CT imaging morphology can be classified into three patterns, which seem to correlate with the clinical subtypes. Each pattern depicts its own set of distinctive imaging features. In this review, we briefly outline the clinical and imaging features of the three distinct forms of ALA, and discuss the role of percutaneous drainage in the management of ALA.

Caudate lobe amebic abscesses: percutaneous image-guided aspiration or drainage. Abdom Radiol (NY) 2022; 47:1157-1166. [PMID: 34964910 DOI: 10.1007/s00261-021-03395-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 12/17/2021] [Accepted: 12/20/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Amebic liver abscess is the most common type of liver abscess on a worldwide basis, with caudate lobe being a relatively uncommon location for its occurrence. Abscess in caudate lobe of liver is often considered a challenging location for image-guided percutaneous drainage due to its difficult-to-access location along with close relationship with major vessels at porta hepatis. PURPOSE This study aims to demonstrate safety and efficacy of percutaneous drainage for caudate lobe amebic abscess. MATERIALS AND METHODS In this retrospective study, hospital database was electronically searched for patients having caudate lobe amebic abscess that underwent percutaneous catheter drainage/needle aspiration (PCD/PNA) between January 2016 and January 2021. The etiology, risk factors, microbiology, complications, different approaches for PCD/PNA, and their outcome were studied and reported. RESULTS Of 30 patients having caudate lobe amebic abscess treated with PCD/PNA, solitary caudate lobe abscess was seen in 29, whereas one patient had more than one abscesses in caudate lobe. Contained and free intraperitoneal rupture of the abscess were seen in 9 (30%) and one patient, respectively. Ten (32%) patients had associated vascular thrombosis, while 2 patients were found to have abscess-biliary communication. Twenty-six (86.7%) patients were treated with PCD, while remaining 4 (13.3%) with PNA. On Univariate analysis, factors such as volume, multilocularity, and contained rupture of the abscess were found to be significantly increasing the duration of percutaneous drainage (PCD), while only multilocularity (p value 0.007) continued to show statistical significance on Multivariate analysis. Venous thrombosis and duration of catheter drainage were the two factors found to have significant influence on the length of hospital stay on Univariate as well as Multivariate analysis (p value 0.05 and 0.001, respectively). The rates of catheter manipulation were also significantly higher in patients with abscess showing complex internal configuration (heteroechoic contents and/or multilocularity). Technical and clinical success rates of 100% and 96.7% were achieved through percutaneous interventions (PCD/PNA), despite the complex location of abscesses and associated complications, with no incidence of vascular injury. CONCLUSION Liver abscess in caudate lobe can be accessed by different routes for percutaneous drainage, despite being surrounded by large vessels and its deep location, without major complications. Thus, PCD/PNA may be considered as a first-line therapy for the management of caudate lobe amebic abscesses in adjunct to medical therapy.

Abstract
Background Pyogenic liver abscesses (PLAs) represent potentially life‐threatening abdominal conditions that require immediate diagnosis and therapy. European and American incidence figures vary between one and 15 per 100,000 per year. Structured epidemiological data for European countries are not available. Objective To systematically characterize the epidemiology and clinical outcome of PLA in Germany. Methods In representative statutory health insurance data from four million people in 2013–2019, the prevalence and incidence with clinical coding of International Statistical Classification of Diseases and Related Health Problems (ICD)‐10 code K75.0 were selected (n = 1118). Furthermore, demographics, relevant comorbidities, hospitalizations, mortality and complications were determined within one year. Results The incidence of PLA was approximately seven per 100,000. The average age at diagnosis was 66 years; 65% were male. Of these, biliary disease was documented in over 60% and infectious intestinal diseases were found in 21% within the same or previous calendar year. PLA patients had high comorbidity indices. Liver transplant status, malignancies of the liver and biliary system, liver cirrhosis and pancreatitis were strongly associated. Intensive care was documented in 27% of PLA cases. Nine percent died within 12 months, most with an underlying malignant disease. Conclusion Pyogenic liver abscess is a rare disease with high morbidity. Predisposing and risk factors include intestinal and biliary diseases as well as hepatic malignancies. Further research should focus on PLA therapy within prospective surveys and controlled clinical trials.
