Absceso hepático piógeno en pediatría: experiencia en un centro pediátrico de referencia / Pyogenic liver abscess in children: clinical experience in a pediatric reference center

Introduction: Liver abscess is a serious and an uncommon pediatric disease. Objective and Method: Description of 20 pediatric patients with liver abscess admitted in "Ricardo Gutierrez" Children’s Hospital, a Tertiary Reference Center of Buenos Aires, between 2009 and 2015. Results: The hospitalization rate was 35/100.000 admissions. Median age was 5 years old, male/female ratio 4/1. Five patients (25%) had predisposing factors. Median days at diagnosis were 12. Features: Fever 100%, prolonged fever 60%, abdominal pain 50%. The majority had leukocytosis and elevated CRP (median 160 mg/L). Liver enzymes were elevated in only 40% of patients. Ultrasonography detected 90%. A single abscess was observed in 60%; localized at right hepatic lobe, 65%. Purulent material was positive in 12/17 (70%) and bacteremia was present in 3/20 (15%). Wide empirical antibiotic therapy was used. Treatment shift was needed in four patients. The median days of intravenous antibiotics were 30 and the median of total treatment were 53. Surgical procedures were performed in 13/20 (65%). Conclusion: Community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) was the most frequent pathogen, especially in healthy children that associated skin or respiratory illness. Appropriate antibiotic treatment and eventual drainage allows good outcome without sequela or deaths.

Todos los pacientes presentaron fiebre, 60% síndrome febril prolongado y 50% dolor abdominal. La mayoría tenía leucocitosis y PCR elevada (mediana 160 mg/L). Sólo 40% tuvo alteración de pruebas hepáticas. En 90% de los casos el diagnóstico se realizó por ecografía, 65% estaban localizados en el lóbulo derecho; 60% eran lesiones únicas. Hubo aislamiento microbiológico en 12/17 (70%) y en 3/20 (15%) de hemocultivos. Todos recibieron tratamiento antibacteriano empírico de amplio espectro. La mediana de tratamiento antibacteriano intravenoso fue 30 días y en total 53 días. Se realizó drenaje quirúrgico en 13 casos. Todos evolucionaron favorablemente. Conclusión: Staphylococcus aureus resistente a meticilina de la comunidad (SARM-AC) fue el patógeno predominante, especialmente en niños previamente sanos asociados a un foco cutáneo o respiratorio.

Pyogenic liver abscess: diagnostic and therapeutic management / Abscesso hepático piogênico: manejo dos recursos diagnósticos e terapêuticos

ABSTRACT Background: The pyogenic liver abscess has an incidence of 1.1/1,000 habitants. Mortality can reach 100%. The use of less invasive procedures diminish morbidity and hospital stay. Aim: Identify risk factors in patients who underwent percutaneous drainage guided by ultrasound as treatment. Method: Were analyzed 10 patients submitted to the method. Epidemiological characteristics, laboratory markers and imaging exams (ultrasound and CT) were evaluated. Results: The majority of the patients were men with mean age of 50 years old. Liver disease, alcoholism and biliary tract disease were the most common prodromes. Abdominal pain (90%), fever (70%) and jaundice (40%) were the most common clinical manifestations. Mortality of 20% was observed in this series. Hypoalbuminemia and days of hospitalization had a statistically significant positive association with death. Conclusion: The pyogenic liver abscess has subacute evolution which makes the diagnosis difficult. Image exams have high sensitivity in diagnosis, particularly computed tomography. Percutaneous drainage associated with antibiotic therapy is safe and effective therapeutic resource.

RESUMO Racional: O abscesso hepático piogênico tem incidência de 1,1 por 1.000 habitantes com mortalidade podendo chegar a 100%. O uso de recursos menos invasivos diminuem morbimortalidade e tempo de internação hospitalar. Objetivo: Identificar fatores de risco no abscesso hepático piogênico tratado por drenagem percutânea guiada por ultrassom. Método: Total de 10 pacientes foram submetidos ao procedimento. Foram avaliadas características epidemiológicas, marcadores laboratoriais exames de imagem (ultrassom e tomografia). Resultados: Na amostra houve predominância do sexo masculino, com média de idade de 50 anos. Hepatopatia, etilismo e doença da via biliar foram os pródromos mais frequentes. Dor abdominal (90%), febre (70%) e icterícia (40%) foram manifestações clínicas mais comuns. Houve mortalidade de 20% nesta série. Hipoalbuminemia e dias de internação hospitalar tiveram associação positiva com óbito estatisticamente significante. Conclusão: O abscesso hepático piogênico tem evolução subaguda o que dificulta o diagnóstico. Exames de imagem têm sensibilidade alta na propedêutica diagnóstica, notadamente a tomografia computadorizada. A drenagem percutânea, associada à antibioticoterapia, mostrou ser recurso terapêutico seguro e eficaz.

Multiple Pyogenic Liver Abscesses Caused by Microperforation of an Idiopathic Cecal Ulcer / 대한소화기학회지

Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

Prevalence of and risk factors for endogenous endophthalmitis in patients with pyogenic liver abscesses

BACKGROUND/AIMS: Although pyogenic liver abscesses (PLAs) can be successfully treated, the visual prognosis of patients with endogenous endophthalmitis (EE) associated with a PLA is poor. Early diagnosis and prompt intervention may salvage useful vision. Therefore, we investigated risk factors for EE in patients with PLA, to facilitate early diagnosis. METHODS: Data from 626 patients diagnosed with PLA between January 2004 and July 2013 were analyzed retrospectively. Patients were divided into two groups: those with liver abscess-associated endogenous endophthalmitis (LAEE) and non-LAEE. RESULTS: The prevalence of EE in PLA patients was 1.92%. The mean age for all patients (373 males, 59.6%) was 62.8 years. Upon multivariate logistic regression, a liver abscess or another systemic infection (odds ratio [OR], 5.52; p = 0.005), an abscess in the right superior segment (OR, 5.26; p = 0.035), and Klebsiella pneumoniae infection (OR, 3.68; p = 0.039), were risk factors for LAEE. The final visual outcomes of patients with LAEE included no light perception in seven, hand motion only in three, and decreased visual acuity in two. Vitrectomy and early intravitreal injections of antibiotics improved visual acuity and preserved useful vision. CONCLUSIONS: PLA patients with other systemic infections, abscesses in the right superior segment, and K. pneumoniae infection require close monitoring and early intervention to treat LAEE. Intravitreal antibiotic injections or early vitrectomy may salvage useful vision.

Pyogenic liver abscess caused by Gemella morbillorum / Absceso hepático piógeno causado por Gemella morbillorum

Even though Gemella morbillorum infection (GMI) is rare in humans, it may, nevertheless, cause endocarditis, meningitis, brain abscess, pleural empyema, nephritis, mediastinitis, and - occasionally - liver abscess. We are describing the case of a 64-year-old Caucasian male admitted with fever and abdominal pain. Laboratory parameters revealed inflammation signs, and instrumental examinations showed the presence of diverticula in the ascending colon. Abdominal ultrasound (US) and computer tomography (CT) showed two focal lesions in the right liver lobe. One had the characteristics of a simple cyst; the second was hypoechoic with a low density area, possibly containing necrotic material. US-guided needle biopsy was found negative for neoplastic cells, showing purulent infiltrate. Pus culture was found positive for GMI. Systemic antibiotic therapy, coupled with repeated US-guided needle aspiration, induced the resolution of the hepatic abscess. Few cases have been reported of hepatic abscess caused by GMI in immunocompetent non-cirrhotic subjects.

A pesar de que la infección por Gemella morbillorum (GMI, por el término en inglés) es poco común en seres humanos, puede causar endocarditis, meningitis, absceso cerebral, empiema pleural, nefritis, mediastinitis y en ocasiones, absceso hepático. Describimos el caso de un hombre caucásico de 64 años que ingresó con fiebre y dolor abdominal. Los parámetros de laboratorio revelaron signos de inflamación y los exámenes mostraron la presencia de divertículos en el colon ascendente. La ecografía abdominal (US) y la tomografía computarizada (CT) mostró dos lesiones focales en el lóbulo hepático derecho. Una presentó las características de un quiste simple; la segunda fue hipoecóica con una zona de baja densidad, que posiblemente contenía material necrótico. Biopsia con aguja guiada por US dio un resultado negativo para células neoplásicas, mostrando infiltrado purulento. Cultivo de pus fue encontrado positivo para GMI. Una terapia con antibióticos sistémicos, junto con aspiración repetida con aguja guiada por US indujo a la resolución del absceso hepático. Pocos casos se han reportado de absceso hepático causado por GMI en sujetos inmunocompetentes no cirróticos.

Reporte de casos:Se recolectaron los datos de las historias clínicas del HUV de 14 niños menores de 15 años de edad con diagnóstico de primera vez de AH con presencia de la triada clínica diagnostica y confirmados ecográficamente. Se analizaron variables como edad, género, procedencia, signos y síntomas, tiempo de evolución, y paraclínicos de diagnóstico al igual que manejo instaurado; encontrándose edad 8,7 años, con diagnóstico de primera vez, 7 masculinos, 11 procedentes del Valle del Cauca, con un tiempo de evolución entre 2 y 30 días (11,2 días) y una estancia hospitalaria entre 6 y 90 días (21,7 días). Otros síntomas incluyeron vómito en 8/14, anorexia y diarrea en 3/14, tos en 2/14 y cefalea y astenia en 1/10. Presentaron desnutrición aguda 3/7, crónica 3/7 y global 5/7. En 13/14 ecografías abdominales se encontraron AH localizados del lado derecho, siendo únicos en 11/13. Otros paraclínicos evidenciaron: hipoalbuminemia en 5/6, incremento de la VES y PCR en 14/14 y alteración de las pruebas de funcionamiento hepático en 3/7. En 9/14 niños los cultivos del material de drenaje de colección identificaron E.coli, S. viridans, S. epidermidis y P. aureginosa. 2/6 presentaron amibas al examen de heces Conclusión:El AH se debe sospechar clínicamente ante la triada fiebre, hepatomegalia y dolor abdominal de predomino en hipocondrio derecho, corroborar su localización y tipo de presentación con una ecografía abdominal, apoyar su diagnóstico con algunos paraclínicos en sangre y heces, e iniciar su pronto y adecuado manejo médico con antiparasitarios y antibióticos siguiendo una adecuada evolución y así evi tar sus complicaciones que pueden ocasionar mayor morbimortalidad.

Case Report:We collected data from medical records of HUVof 14 children under 15 years of age with first-time diagnosis of liver abscess in the presence of the clinical triad diagnosed and confirmed sonographically. We analyzed variables such as age, gender, signs and symptoms, evolution time, clinical and laboratory data for diagnosis as well as established management; finding age 8.7 years ofage with first time diagnosed, 7 male 11 from the Valle del Cauca, with a time between 2 and 30 days (13.5 days) and hospital stay between 6 and 90 days (21,7 days). Other symptoms included vomiting in 8 /14, anorexia and diarrhea in 3/14, cough in 3/14, and headache and asthenia in 1 / 10. Acute malnutrition showed 3 / 7, chronic 3 / 7, global 5 / 7. The abdominal ultrasounds were located AH on the right, being unique in 11/13. Other paraclinical showed: albumin in 5 / 6, increased ESR and CRP 14/14 and impaired liver function tests in 3 / 7. In 9 / 14 children's material culture collection identified drainage E. coli, S. viridans, S. epidermidis and P. aeruginosa. 3 / 6 presented amoebas to stool examination. Medical management lasted between 10 and 42 days (17.7 days) with antibiotics such as oxacillin, clindamycin, metronidazole, amikacin, ceftriaxone, cefotaxime, ampicillin-sulbactam, piperacillintazobactam, metronidazole being used in 13 / 14. 9 / 10 required surgical drainage guided by ultrasound.Conclusion:The AH should be suspected clinically with the triad fever, hepatomegaly and right upper quadrant abdominal pain, verify their location and type of presentation with an abdominal ultrasound, supporting some paraclinical diagnosis with blood and feces, and initiate a prompt and suitable worming and medical treatment with appropriate antibiotics following developments, thereby avoiding the complications that can lead to increased morbidity and mortality.

Clinical Features of Pyogenic Liver Abscess according to Age Group / 대한소화기학회지

BACKGROUND/AIMS: Pyogenic liver abscess remains a major diagnostic and therapeutic challenge, despite advances in diagnostic technology and new strategies for treatment. This study was conducted to compare the differences in clinical features and outcomes of pyogenic liver abscess according to age. METHODS: In total, 166 patients were enrolled and included 63 (75 years old, group III) patients in each group. We reviewed the medical records retrospectively including etiology, underlying diseases, characteristics of the liver abscess, laboratory and microbiologic findings, treatment, and outcome of the patients. RESULTS: Group I had higher prevalence rates of male patients and chronic alcoholics, but lower prevalence rates of biliary disease, hypertension, and malignancy. In laboratory findings, group II had higher incidence of thrombocytopenia, elevated blood urea nitrogen and creatinine. There were no differences in symptoms and microbiologic findings in blood and pus among the three groups. Liver abscesses were more common in right liver in Group I. The lengths of stay and the treatment modalities were similar in three groups. CONCLUSIONS: Although there were differences in sex ratio, etiology, underlying disease among the different age groups, they did not cause difference in treatment and clinical outcome of pyogenic liver abscess. Thus, we recommend active treatments in patients of all age.

Comparison of Clinical Characteristics between Cryptogenic and Biliary Pyogenic Liver Abscess / 대한소화기학회지

BACKGROUND/AIMS: The aim of this study was to evaluate the characteristics of cryptogenic and biliary pyogenic liver abscess by comparing the clinical aspects between the two groups. METHODS: Of 119 patients treated for pyogenic liver abscess from 2000 to 2004, 82 subjects with cryptogenic liver abscess and 21 with biliary abscess were analysed retrospectively. RESULTS: There were no significant differences between the two groups regarding clinical symptoms. The characteristics of abscess were similar except the size of abscess. The size of abscess less than 5 cm in diameter was more common in billiary group than in cryptogenic group (p=0.004). Compare to cryptogenic group, biliary group had more positive culture test from abscess (100% vs. 69%, p=0.006). Especially, E. coli isolated from abscess culture (28% vs. 7%, p=0.014) and blood culcure (23% vs. 4%, p=0.035) were more common in biliary group than in cryptogenic group. There was no difference in mortality between the two groups (biliary vs. cryptogenic: 4.8% vs. 0%, p=0.204). However, the rate of clinical improvement was higher in cryptogenic group than in biliary group (92.7% vs. 66.7%, p=0.001). CONCLUSIONS: Biliary liver abscess had similar clinical characteristics to cryptogenic origin. Biliary liver abscess had smaller abscess size and more positive abscess culture rates than cryptogenic abscess. Improvement rate without complication and recurrence was higher in cryptogenic group than biliary group.

A Case of Salmonella Liver Abscess / 대한소화기학회지

Liver abscess can be caused by bacterial, parasitic, or fungal infection. Amebic abscesses are more common, but pyogenic abscesses account for three quarters of hepatic abscess in developed countries. Most common pathogens of the pyogenic liver abscess are Escherichia coli, Klebsiella pneumoniae, Bacteroides, Enterococci, Streptococci, and Staphylococci. However, liver abscess caused by Salmonella species has rarely been reported. We experienced a case of Salmonella liver abscess which improved after antibiotic therapy and percutaneous drainage. The patient was 52 years-old man who had an episode of intermittent fever, chills and epigastric pain for 2 weeks. He was diagnosed as liver cirrhosis eight years ago and diabetes three years ago. Salmonella group D, non-typhi was cultured from blood and pus from the liver respectively at the same time. With percutaneous drainage and susceptible antibiotic therapy, liver abscess decreased in size with improvements in fever and abdominal pain.
