Assessment of risk factors in pyogenic liver abscesses in children.

Background: Pyogenic liver abscess (LA) is a significant contributor to morbidity and mortality in developing countries like India. The risk factors predisposing to the LA specifically in children are not known. Studies done in the past largely remain inconclusive and have identified only probable causes. The cause of LA in children with no coexisting illness remains unknown. Methodology: This prospective observational study was conducted at a tertiary teaching hospital located in New Delhi, India. All children between 2 months and 12 years of age with sonographically confirmed LA presenting to the hospital were included and managed with appropriate intravenous antibiotics and relevant investigations. Results: A total of 52 children were included. The mean age was 6 years and 4 months, and the male: female ratio was 1.4:1. Around 50% of the patients were malnourished. Fever, abdominal pain and loss of appetite were the most common symptoms. Nine patients (17%) were managed conservatively, 13 (25%) needed percutaneous needle aspiration and 30 (57.69%) required drainage using a pigtail catheter. Poor socioeconomic status and anaemia were found to be the most commonly associated risk factors. Selective immunoglobulin A (IgA) deficiency was the most common primary immunodeficiency disorder followed by T-cell defect. On multivariate analysis, it was seen that in those with clinical icterus, gamma-glutamyl transferases >350 IU/m, and those with impending rupture, the time to defervescence was significantly different (P = 0.05). Conclusion: Poor socioeconomic status causing malnutrition emerged as a significant risk factor for LA in children. Selective IgA deficiency was the most common immunodeficiency seen in a few children. Adopting a conservative approach like aspiration and percutaneous drainage led to lower mortality and good recovery rates.

Pyogenic liver abscess: incidence, causality, management and clinical outcomes in a New Zealand cohort.

AIMS: The determinants, management and outcomes of pyogenic liver abscess [PLA] are changing. We aimed to compare these in a New Zealand cohort. METHODS: We have retrospectively reviewed all PLA cases presenting to Christchurch Hospital over 12 months between 2014 and 2015. RESULTS: Twenty-five cases presented over this period. The incidence was 5/100,000. Eighty percent were Caucasian with overall 4:1 male preponderance. Commonest comorbidities were diabetes, hypertension, atrial fibrillation and immunosuppression. Underlying pancreatico-biliary disease featured in 20%, preceding Whipple's or hepatic resection in 24% and inflammatory bowel disease [IBD] in 12%. Commonest complication was septic shock with intensive care unit admission in four cases. The evident cause was recent Whipple's procedure or hepatic resection (24%), pancreatico-biliary (16%), diverticulitis (12%) and active IBD (8%). Cause remained cryptogenic in 28%. The commonest microorganism was Streptococcus intermedius. The management comprised of: antibiotics alone (n=6), needle aspiration (n=2), catheter drainage (n=14), biliary drainage (n=3), surgical drainage (n=2). These interventions were in accordance with current international recommendations. There were no deaths and the mean length of stay was 10.3 days. CONCLUSION: PLA continues to carry significant morbidity. Demographics, including ethnicity, play an important role. Our tertiary centre cohort may account for higher incidence and better clinical outcomes.

Impact of advanced age on inpatients with pyogenic liver abscess in Taiwan: a nationwide claim-based analysis.

BACKGROUND: Pyogenic liver abscess (PLA) is seen as an endemic disease in population of Taiwan. The impact of advanced age on inpatients with PLA remains unclear. METHODS: Data was collected and analyzed from claims of discharges by inpatients with PLA, using the National Health Insurance Research Database of 2007. RESULTS: A total of 2319 subjects and 2651 related discharges were enrolled, including 939 subjects/1077 discharges ≥65 years and 1380 subjects/1574 discharges <65 years. Subjects ≥65 years had significantly higher ratios of females to males, nephropathy, biliary tract diseases, liver cirrhosis and gastroenterological cancers than those <65 years. Hepatic/intra-hepatic duct cancers accounted for the most comorbid gastroenterological cancers. Discharged of subjects ≥65 years had longer hospital stays, more in-hospital death/critical discharge, and a higher ratio of acute low respiratory conditions (ALRC) and urological infections than those of subjects <65 years (p<0.05). The inpatient costs for subjects ≥65 years were significantly higher than those for subjects age<65 years in blood products, hemodialysis and total hospitalization. Co-morbidities, such as nephropathy, biliary tract diseases, liver cirrhosis, gastroenterological cancers, ALRC and urological infections were predictive variables associated with age ≥65 years in patients with PLA, as were being female and in-hospital death/critical discharge. Nephropathy and gastroenterological cancers were predictive variables associated with poor prognosis (in-hospital death/critical discharge) in both PLA patients age < and ≥65 years (p<0.05). Diabetes mellitus featured predominantly, but had no impact on distribution and prognosis. CONCLUSION: Advanced age (≥65 years) had an impact on the aforementioned characteristics and predictive variables in inpatients with PLA. Physicians should pay attention and treat aged PLA patients with greater care, especially those cares with comorbid nephropathy or gastroenterological cancers.

Percutaneous and surgical treatment of pyogenic liver abscesses: observation over a 21-year period in 148 patients.

BACKGROUND: Percutaneous drainage of pyogenic liver abscess has become first-line treatment. In the past surgical drainage was preferred in some centres. AIM: The aim of this retrospective study was to assess the effectiveness of percutaneous treatments and surgical drainage, in terms of treatment success, hospital stay and costs. PATIENTS: Data of 148 patients (90 males; 58 females; mean age, 61 yrs; range, 30-86 yrs) were retrospectively analysed. METHODS: Patients' outcomes, including the length of hospital stay, procedure-related complications, treatment failure and death, were recorded. Multiple logistic regression model was used for statistical analysis. RESULTS: One hundred and four patients (83 with solitary and 21 with multiple abscesses) were treated percutaneously, either by needle aspiration (91 patients) or catheter drainage (13 patients) depending on the abscess's size, and 44 patients (30 with solitary and 14 with multiple abscesses) were treated surgically. There was no statistically significant difference in patients' demographics or abscess characteristics between groups. Hospital stay was longer, and costs were higher in patients treated surgically (p<0.001). There was statistically significant difference in morbidity rate between groups (p<0.001). No death occurred in both groups. CONCLUSIONS: Percutaneous and surgical treatment of pyogenic liver abscesses are both effective, nevertheless percutaneous drainage carries lower morbidity and is cheaper.
