OBJECTIVES: Melioidosis is associated with extremely high case fatality ratios. The aim of this study was to determine whether detection of abdominal visceral abscesses can facilitate diagnosis of melioidosis in children.

METHODS: We conducted a retrospective analysis of all children who had liver and/or spleen abscesses on abdominal ultrasonography admitted to Bintulu Hospital in Sarawak, Malaysia, from January 2014 until December 2018.

RESULTS: Fifty-three children had liver and/or spleen abscesses. Spleen abscesses were present in 48 (91%) cases; liver abscesses in 15 (28%). Melioidosis was confirmed by culture in 9 (17%) children; small occult splenic abscesses were present in all cases. In 78% of these cases, the lesions were detected before any positive culture (or serology) results were available. Four (8%) children had bacteriologically-confirmed tuberculosis. Two (4%) had Staphylococcus aureus infection. Of the remaining 38 (72%) culture-negative cases, 36 (95%) had clinical and imaging characteristics similar to that of children with culture-confirmed melioidosis and improved with empirical melioidosis antibiotic therapy.

CONCLUSIONS: A large number of children in Bintulu Hospital in Sarawak, Malaysia, were found to have spleen abscesses. Melioidosis was the most common etiology identified in these children. Abdominal ultrasonography is extremely useful in facilitating the diagnosis of pediatric melioidosis.

Independent evaluations of XEh Rapid®, an IgG4-based rapid dipstick test, were performed to assess its diagnostic performance to detect amebic liver abscess (ALA) using 405 samples at seven laboratories in four countries. The test showed high diagnostic specificity (97-100%) when tested with samples from healthy individuals (n = 100) and patients with other diseases (n = 151). The diagnostic sensitivity was tested with a total of 154 samples, and the results were variable. It was high in three laboratories (89-94%), and moderate (72%) and low (38%) in two other laboratories. Challenges and issues faced in the evaluation process are discussed. Nevertheless, XEh Rapid is promising to be developed into a point-of-care test in particular for resource-limited settings, and thus merits further confirmation of its diagnostic sensitivity.

PMID: 1788579

This paper deals with two patients with typhoid fever in whom hepatic manifestations were the dominant and presenting features of the illness. The ability of typhoid hepatitis to simulate other common infectious diseases in this region is highlighted. It is recommended that typhoid hepatitis should be included in the differential diagnosis of patients presenting with fever and jaundice particularly in the tropics.

Entamoeba histolytica is the second major cause of liver abscess disease in humans, particularly in developing countries. Recently, DNA molecular-based methods have been employed to enhance the detection of E. histolytica in either pus or stool specimens. In this study, the results of real-time polymerase chain reaction (PCR) to detect E. histolytica DNA in pus from liver abscess cases were compared with those of indirect hemagglutination assay on the corresponding serum samples. Bacterial cultures were also performed on the pus samples for the diagnosis of pyogenic liver abscess. The real-time PCR detected E. histolytica DNA in 23 of 30 (76.7%) pus samples, when compared with 14 of 30 (46.7%) serum samples in which anti-Entamoeba antibodies were detected by indirect hemagglutination assay and 4 of 30 (13.3%) pus samples that showed bacterial infection by culture. The use of real-time PCR is a promising detection method for diagnosis and epidemiology assessment of amoebic liver abscess.

PMID: 17694959 MyJurnal

Edwardsiella tarda has recently been described as a member of the family Enterobacteriaceae. The genus Edwardsiella contains three species; E. hoshinae, E. ictaluri and E. tarda. Edwardsiella tarda is the only species which has been recognised as pathogenic to humans, especially in those with an underlying disease. The most common presentation is watery diarrhoea. Extra intestinal infections have been reported infrequently. Humans seem to be infected or colonised with Edwardsiella through ingestion or inoculation of a wound. This report is of a patient with multiple liver abscesses due to E. tarda who later developed bacterial peritonitis and septicaemic shock.

Amoebic liver abscess (ALA) is the most frequent clinical presentation of extra-intestinal amoebiasis. The diagnosis of ALA is typically based on the developing clinical symptoms, characteristic changes on radiological imaging and serology. Numerous serological tests have been introduced for the diagnosis of ALA, either detecting circulating amoebic antigens or antibodies. However those tests show some pitfalls in their efficacy and/or the preparation of the tests are costly and tedious. The commercial IHA kit that used crude antigen was reported to be useful in diagnosis of ALA, however high antibody background in endemic areas may cause problems in its interpretation. Thus, discovery of well-defined antigen(s) is urgently needed to improve the weaknesses of current serodiagnostic tests.

International e-Journal of Science, Medicine & Education, 2018;12(1):27-31.

MyJurnal

Amoebiasis is a parasitic infection caused by the
intestinal protozoan Entamoeba histolytica, most
prevalent in developing countries. It results in 40,000 to
100,000 deaths each year from amoebic colitis and extra
intestinal infections. Amoebic liver abscess (ALA)
is the most common extra intestinal site of infection
with an incidence of between 3% and 9% of all cases of
amoebiasis. Ultrasound which has a sensitivity of more
than 90% for detecting ALA is highly recommended
as an initial investigation followed by serological
demonstration of circulating antibodies specific to
Entamoeba histolytica.

PMID: 6253701

We present a study of 288 hepatic resections carried out in Malaysia for the past fifteen years. First, we describe our indications for hepatic resectins which are not limited to hepatic trauma and hepatomas, but also include hepatic abscesses, cysts, intrahepatic calculi and hemangiomas. Second, we give a simplified classification of hepatic resections using accurate terminology. Third, we describe the safety of hepatic resections in our hands which we believe is due to specially designed surgical instruments and the accurate decision making process at surgery. We have had minimum postoperative mortality and no intraoperative deaths so far. Finally, while analysing each indication we have drawn vignettes from our experience for the past fifteen years.

PMID: 6259961

Two hundred eight-eight hepatic resections performed over the past 15 years are discussed. The safety and success achieved are attributed to the original work in Malaysia on the anatomy of the liver and its anomalies, the use of surgical instruments specially designed for hepatic resection, various types of resections devised and studies on aids to liver regeneration after resection. The diversity of the principles and practice of surgery in the Western countries compared with those in Malaysia is illustrated.

Fulltext A study on the usefulness of Techlab Entamoeba histolytica II antigen detection ELISA in the diagnosis of amoebic liver abscess (ALA) at Hospital Universiti Sains Malaysia (HUSM), Kelantan, Malaysia

Zeehaida M, Wan Nor Amilah WA, Amry AR, Hassan S, Sarimah A, Rahmah N

Trop Biomed, 2008 Dec;25(3):209-16.

PMID: 19287359

Amoebic serodiagnosis at Hospital Universiti Sains Malaysia (HUSM), Kelantan employs an indirect haemagglutination assay (IHA) which detects anti-Entamoeba histolytica antibodies in patients' serum samples. In an amoebiasis endemic area such as Kelantan, interpretation of a positive IHA result can be problematic due to the high background antibody levels. The TechLab E. histolytica II ELISA is a commercial kit for detection of specific Gal/GalNAc lectin antigen in stool samples, and has been reported to be able to detect the antigen in serum samples from patients with amoebic liver abscess (ALA). Thus in this study we investigated the usefulness of TechLab E. histolytica II ELISA for diagnosis of ALA by comparing it with IHA. This is a cross sectional study involving 58 suspected ALA patients who were admitted to the surgical ward, HUSM, Kelantan. The diagnosis of ALA was established based on clinical symptoms and signs, ultrasound and/or CT scan results. The serum specimens obtained from the patients were tested with IHA (Dade Behring Diagnostics, Marburg, Germany) and TechLab E. histolytica II ELISA (Techlab, Blacksburg, Virginia, USA) according to the manufacturers' instructions. Of the 58 patients, 72.4% (42) were positive by IHA and only 8.6% (5) were positive by the TechLab E. histolytica II ELISA. Agreement between the IHA and ELISA was poor (kappa value 0.019, p=0.691). There was also no correlation between ELISA results and IHA antibody titers. The TechLab E. histolytica II ELISA was not sensitive in detecting amoebic antigen in samples from ALA patients. In addition the results of the test did not correlate with the IHA anti-E. histolytica antibody titres. Therefore, the TechLab E. histolytica II ELISA was found not to be useful for serological diagnosis of ALA at HUSM.

PMID: 33842136 DOI: 10.7759/cureus.13760

Melioidosis is an infectious disease most commonly found in places with tropical climates. Definitive diagnosis can be confirmed by culture or pathological results of blood or infected organ. However, imaging study is helpful in providing early provisional diagnosis and guiding therapy. Point-of-care ultrasound can be currently performed bedside by non-radiological staff such as emergency physicians or intensivists. We present the case of a pediatric patient who got diagnosed with melioidosis after detection of multiple splenic and hepatic abscesses by point-of-care ultrasound, leading to early diagnosis and appropriate empirical antibiotic selection, resulting in good treatment outcome.

Amoebiasis, caused by Entamoeba histolytica, is one of the leading parasitic infections in the world. This study was aimed at profiling antigenic membrane proteins of a virulent variant of E. histolytica HM-1:IMSS. The membrane proteins were extracted using ProteoExtract® kit (Merck, Darmstadt, Germany) or conventional method, separated using OFFGEL 3100 fractionator (Agilent Technologies, Santa Clara, California), followed by SDS-PAGE and Western blot analysis. Selected antigenic membrane proteins were identified using LC-ESI-MS/MS. Subsequently, the proteins were classified according to their biological processes and predictions were made on membrane and membrane-associated proteins. When the proteins were probed with pooled sera from amoebic liver abscess (ALA) patients, 10 and 15 antigenic proteins with molecular weights 25 to 200 kDa were identified using the ProteoExtract® kit and conventional method, respectively. LC-ESI-MS/MS identified 13 antigenic proteins, and both extraction methods predicted six of them as membrane and membrane-associated proteins. The topmost biological processes which comprised of six proteins were involved in cellular processes.. These antigenic membrane proteins merit further investigations as potential candidates for vaccine studies.

MyJurnal

Hypervirulent Klebsiella pneumoniae strain is a major cause of liver abscess and this bacteria has metastatic properties. This distinct liver abscess syndrome has been increasingly reported in Asia over the past two decades, but is emerging as a global disease. We described an 81-year-old lady, who presented to the emergency department with 1-week prior duration of fever and right eye swelling. She had been admitted for recurrent liver abscess prior to this. Hence, she was initially treated as sepsis secondary to recurrent liver abscess. Meanwhile, she was managed concurrently by ophthalmology team for endophtalmitis. Despite the initiation of treatment with antibiotics, she did not show any improvement and required right eye evisceration to treat the sepsis. Invasive liver abscess syndrome with metastatic endophthalmitis should be screened in patient with Klebsiella liver abscess. They should be monitored for ocular symptoms as early recognition can prohibit delays in treatment, which has debilitating consequences.

PMID: 23959490 MyJurnal

Entamoeba histolytica causes amoebic diarrhoea, colitis and liver abscess (ALA). Diagnosis of ALA is difficult, as most patients do not have simultaneous intestinal amoebic infection. At Hospital Universiti Sains Malaysia (HUSM), diagnosis of ALA relies on a combination of clinical findings, ultrasound examination of the liver and serodiagnosis using a commercial kit. In this study, two in-house indirect ELISAs were developed and evaluated. One of the in-house assays utilises E. histolytica crude soluble antigen (CSA) to detect serum IgG specific to the parasite whereas the other uses E. histolytica ether extract antigen (EEA). Preparation of CSA requires a sonicator to lyse the amoeba whereas EEA was prepared by chemically solubilizing the trophozoites. Based on the cut-off value of mean optical density + 3SD, CSA-ELISA showed 100% (24/24) sensitivity and 93.33% (210/225) specificity; while EEA-ELISA showed 91.67% (22/24) sensitivity and 95.11% (214/225) specificity. In conclusion, both the in-house indirect ELISAs were found to be efficacious for diagnosis of ALA; and the EEA is easier to prepare than the commonly used CSA.
