Fascioliasis* ; Humans*

Human fascioliasis has recently been widely found in many regions of Vietnam confirmed by clinical and laboratory examinations. Therapeutic efficacy of the specific treatment drug for this disease - triclabendazole (provided by WHO) - was investigated in a study conducted in the hospital for tropical diseases, Ho Chi Minh city from November 2004 to August 2005. A total number of 53 patients treated with single dose of triclabendazole 10 mg/kg of body weight were found to have good compliance. All clinical symptoms disappeared within 24 hours of drug administration and three days later the patients were allowed to discharge with the good health status: pinky face, no abdominal pain and fever, normal vital signs, and good general status. All the patients were requested to return to hospital for re-checking after three months. However, only 18 of them had followed the request due to the objective reasons. The returned ones were found to have good health state with no resurgent clinical features and normal laboratory findings except for a slow decrease of antibody titer. The remaining patients were followed up via telephone and mails showed good health status. Triclabendazole was found to be a good anti-fascioliasis drug with high safety and efficacy and low side effects, and is recommended to widely use in treatment for fascioliasis.

During two years (2002-2004) a study was conducted in the Northern parts of Vietnam, 35 fascioliasis patients have been determined in 15 provinces. The clinical symptoms found in these patients were pain in the right quadrian of chest 94.3%, fever 60.0%, weight loss 57.1%, indigestion 54.3%, digestive disorder 42.9%, upper abdominal pain 42.9%, allergery 17.1%, out-penetration of adult worm from knee-joints 2.9%. The sub-clinical symptoms detemined by ultrasound images were liver abscesses with mixed echo (100%), eosinophillia in 34 patients (97.1%), Fasciola eggs in stool (25.7%), ELISA (+) with Fasciola gigantica antigen (100%) and almost by title of 1/12,800. Within those patients had been followed, some biochemical index of liver and kidney (GOT, GPT, Creatinin, Ure) were unchanged.

A case of ectopic fascioliasis involving cecum and ascending colon was reported. This case was a 19-year old Korean female who had a history of postprandial aggravation of intermittent abdominal pain of 3 weeks duration. She was presented with an abdominal mass in the right upper quadrant, for which an operation(right hemicolectomy) was performed. Whole cecum and ascending colon showed multifocal tunnel-like necrotizing granulmas with central cavitations. Numerous Charcot-Leyden crystals were seen along tracts of the worm. The lesion was distributed throughout the entire thickness of the wall. Parasitological examination confirmed the worm found in the intestinal wall to be juvenile form of Fasciola species. Possibilities were discussed on the localization of the fluke and the mode of infection of present case.

Parasitic diseases are widely distributed throughout the world. Recently, travel abroad and migration from abroad are increasing in Korea. Therefore, it is necessary to appropriately control imported parasitic disease. The drugs for the treatment of the parasitic diseases that can be imported from abroad are reserved by the government. To guide proper treatment of parasitic diseases, recommended chemotherapy focused on these reserved drugs has been introduced. The diseases reviewed in this article include malaria, babesiosis, toxoplasmosis, leishmaniasis, Chagas disease, African sleeping sickness, filariasis, angiostrongyliasis, and fascioliasis. Because most of the parasitic diseases produce severe illness or fatal results, rapid and accurate diagnosis is important and following fully the recommended therapy is needed. The recommended drug therapy changes from time to time due to various factors, so always recognizing and applying the latest therapy and is very important.

Fascioliasis has not been confirmed as a human disease entity until now in Korea despite of sporadic discovery of ova of Fasciola sp. in human fecal materials being never traced to the confirmation of infection. Almost all of the cases with ova in their stool have been related with consumption of cattle liver whether eaten in raw or processed. The present authors confirmed a human fascioliasis case who was a Korean housewife of 42-year-old living in Seoul, during the exploratory laparotomy. The patient had been healthy until October 1975 when abrupt onset of urticaria, dyspepsia, epigastric discomfort developed. And the fluctuation of these symptoms was followed by epigastric colicky pain attacks from December 4, 1975. A complete worm of Fasciola sp. was removed during the bile-duct exploration with stone forceps in lower half of common bile duct, on January 20, 1976. The patient only agreed that she had eaten some raw liver of cattle on September 1975 but denied any possible sources of infection such as drinking of untreated water, handling of water flower and grass, and eating of raw watercress. The measurements of the removed worm: 35. 61 mm in body length, 14.00 mm in maximum body width(Length/width ratio, 2.54:1), distribution of testes to body length 33.9 per cent , number of branches of ovary 22, the size of intrauterine ova 157.2 x 108. 4 micrometer in average. These findings are not compatible with the classical descriptions of both Fasciola hepatica and F. gigantica, and it was concluded it is so-called Fasciola sp. which is intermediate between two species as proposed by many Japanese workers.

Fascioliasis in cattle is one of the most common and very serious trematode diseases in Korea. In the present study, the enzyme linked immunosorbent assay (ELISA) was applied in the diagnosis of fascioliasis using antigen of Fasciola hepatica, peroxidase of conjugate anti-cattle IgG and orthophenylenediamine as a substrate by micro-method technique of Voller et al. (1976b) and MacLaren (1978) with a slight modification. Results obtained from the present study are as follows: In assay for optimal dilution of stock antigen, the antigen (protein contents; 0.8 mg/ml) was diluted from 1/50 to 1/600 with carbonate buffer (pH 9.6), and then absorbance values were measured with 1/100 diluted sera. The regression equations between the OD values of ELISA and dilution of antigen were log Y=-0.181-0.00127X in infected sera, and log Y= -0.578- 0.000879X in normal sera. The significantly higher (p<0.05) OD value was observed in the former. In assay for optimal dilution of sera, the sera were diluted from 1/25 to 1/400 with in PBS/ Tween 20(pH 7.4), and absorbance values were measured with 1/200 diluted antigen. The regression equation between the OD values of ELISA and dilution of sera were log Y=-0.1540-0.0007238X in infected sera and log Y=-0.4834-0.00116X in normal sera. The former was higher than the latter (p<0.05). In the 27 cases of negative intradermal test, OD values of the ELISA are 0.447 +/- 0.144, the 95 percent confidence interval (Mean+2 x SD) of the values was 0.735, and there was no case over the values. Therefore, the sensitivity of the antigen to diagnose fascioliasis was 100 percent in the negative case. The OD value 0.7 which is designed as a criterion (detection level of positive one) is useful for the performance of the ELISA in fascioliasis. According to the OD value of criterion in the regression equations, the optimal dilutions of stock antigen and serum were 1/250 and 1/100, respectively. In the 58 cases of fascioliasis from which the adult could be found in the bile ducts, the OD value was 0.846+0.224(-0.224). The 75 percent (44 cattle) among them had higher value with compared to the criterion, and the 60 percent (20 cattle) of the cases of proliferative cholangitis of 33 cattle which had been infected previousely with Fasciola sp. is higher than the criterion. Prevalence of fascioliasis was 43.4 percent in the application of the ELISA to 272 cattle which were reared in Jeonbug district.

The authors would record the fifth case of human fascioliasis in Korea, occurring in a 48 year old Korean man who lived in Munkyong, Kyongsangbuk-do. The diagnosis was based on the morphology and measurements of the eggs which were collected in necrotic debris from the tunnel-like ulcerations of the gallbladder wall which was surgically removed for a gall stone. Although we failed to find out the fluke in the specimen, there found an evidence of once presence of Fasciola in the inflamed wall of the gallbladder in this patient.
