Amebiasis is usually contracted in geographic areas where sanitation is poor, but outbreaks can still occur anywhere that drinking water becomes contaminated with sewage. In the majority of persons infected with the parasite, colonization of the intestine is asymptomatic. In others, symptoms of gastrointestinal distress can appear within a week. In rare cases, extra-intestinal amebiasis can cause abscesses in the liver or elsewhere. Many questions about the disease course in different patients remain to be answered. Diagnosis can be made through symptom identification; findings of right-upper-quadrant tenderness, leukocytosis, and an elevated level of alkaline phosphatase; and testing the feces for trophozoites or cysts. Clinicians disagree on whether asymptomatic persons need to be treated, but anyone who is capable of transmitting the disease should be advised of how to avoid exposing others to it.

Thirteen patients with amebic liver abscess and 26 with pyogenic abscess were identified during a 10 year period. All but one patient with an amebic abscess had emigrated or traveled to areas where amebiasis was endemic. Half of the patients in whom pyogenic abscesses developed had debilitating disease and anemia. Factors predisposing to multiple rather than solitary hepatic abscess were biliary tract disease before surgery, cancer, chemotherapy, steroid administration and alcoholism. Elevated levels of alkaline phosphatase and hypoalbuminemia were present in most patients. Three patients with amebic abscess died, two of whom has massive gastrointestinal hemorrhage from associated amebic colitis. No patient with a solitary pyogenic liver abscess died. Fifteen of 16 patients with multiple liver abscesses died. Failure to consider the diagnosis of liver abscess, confusion over interpretation of the scan, failure to operate or provide a timely operation and failure to adequately explore the abdomen or identify all abscesses were factors responsible for eight unnecessary deaths.

The antiamoebic effect of a crude drug formulation against Entamoeba histolytica was studied. In the traditional system of medicine in India, the formulation has been prescribed for intestinal disorders. It comprises of five medicinal herbs, namely, Boerhavia diffusa, Berberis aristata, Tinospora cordifolia, Terminalia chebula and Zingiber officinale. The dried and pulverized plants were extracted in ethanol together and individually. In vitro amoebicidal activity was studied to determine the minimal inhibitory concentration (MIC) values of all the constituent extracts as well as the whole formulation. The formulation had a MIC of 1000 micrograms/ml as compared with 10 micrograms/ml for metronidazole. In experimental caecal amoebiasis in rats the formulation had a curative rate of 89% with the average degree of infection (ADI) reduced to 0.4 in a group dosed with 500 mg/kg per day as compared with ADI of 3.8 for the sham-treated control group of rats. Metronidazole had a cure rate of 89% (ADI = 0.4) at a dose of 100 mg/kg per day and cured the infection completely (ADI = 0) when the dosage was doubled to 200 mg/kg per day. There were varying degrees of inhibition of the following enzyme activities of crude extracts of axenically cultured amoebae: DNase, RNase, aldolase, alkaline phosphatase, acid phosphatase, alpha-amylase and protease.

An ELISA test for the serological diagnosis of amoebic liver abscess (ALA) was standardized and evaluated in sera from three groups of patients: (1) three patients with diagnosis confirmed by isolation of the parasite, (2) thirty seven patients with diagnosis established by clinical findings and ultrasound studies and (3) seven patients whose diagnosis were established by clinical findings and a positive double immunodifusion test. Ninety one serum samples from healthy subjects and 22 from patients with other liver or parasitic diseases were also included in the study. The optimum concentration of Entamoeba histolytica antigen was 1.25 micrograms/ml and optimum dilutions of serum and anti-human IgG -alkaline phosphatase conjugate were 1:400 and 1:4000 respectively. The cut-off point of the ELISA test in this study was an absorbance value of 0.34. The test parameters were: sensitivity = 95.7%, specificity = 100%, positive predictive value = 100% and negative predictive value = 98.2%. The ELISA test was found to be of great use as a diagnostic tool for the establishment of amoebic etiology in patients with clinical supposition of ALA. The test could also be used for seroepidemiological surveys of the prevalence of invasive amoebiasis in a given population, since it allows the processing of a greater number of samples at a lower cost than other serological tests.

In the period of 1989-1995 seven patients with amebic liver abscess were observed in Clinic of Infectious Diseases of Pomeranian Medical School in Szczecin. The diagnosis has been made on the base of epidemiological data, presence of intrahepatic defect by a scanning procedure of liver (ultrasonography, CT, scintigraphy) and positive serologic test for amebiasis. All patients were male of Polish nationality, 29-57 years old, who became ill after travel to Africa or India. Intestinal amebiasis was present only in two cases. Five patients had acute onset of disease and two chronic. The most common complaints included fever, abdominal pain, anorexia. A cough, chest pain, diarrhea or weight lose were less common. At physical examination paleness of skin, subjaundice, abdominal tenderness, hepatomegaly and sometimes pleural effusion have been observed. Laboratory tests revealed high RBS, leucocytosis and mild anemia. Slightly higher serum level of bilirubin, alkaline phosphatase were transient. Trophozoits of Entamoeba histolytica have been found in stool specimens of one only patient. Amebic antibodies tested with indirect hemagglutination (IHA) were present in all cases. Visual technics have shown abscess of 3 to 9 cm in diameter located at right liver lobe. Six patients have been treated with both chemotherapy (metronidazole or/and dehydroemetine) and "skin needle" aspiration. In two cases recrudescence of abscess has been observed after one and three years respectively. These two patients have been undergone second course of treatment with using not only needle aspiration and metronidazole/dehydroemetine but luminal agents as well.

Thin layer immunoassay was carried out to demonstrate antibodies against Clonorchis sinensis in sera from clonorchiasis patients. Saline extract of adult worm was used as antigen. TIA technique was performed as described earlier by Elwing et al. (1976), but agarose was used instead of agar. The antibody titres of sera in 60 clonorchiasis cases were higher than that of 10 healthy and 10 amoebiasis cases, but not different comparing with that of 10 paragonimiasis cases. Antibody titres in clonorchiasis gave no differences according to the age, sex, EPG in feces, eosinophilia degree of blood, level of alkaline phosphatase and transaminase (SGOT, SGPT) in sera. It is suggested that, after evaluation, the TIA might supplement or be used as an alternative to other immunodiagnostic tests already in use for the diagnosis of clonorchiasis.
