In 74 patients with clonorchiasis, the efficacy and safety of praziquantel was evaluated in a two-phase study: a double-blind, randomized controlled trial of praziquantel versus placebo (42 patients) and an open study (32 patients). All but one of the patients were Laotians. The intensity of clonorchiasis was light in 85% (63 of 74) and moderate in 15% (11 of 74) of the patients. Cure based on our established criteria was noted in 67 of 67 patients (100%) treated with praziquantel at a dose of 75 mg/kg per day. In contrast, four patients (20%) in the placebo group, each with light infection, ceased passing eggs and were, according to our established protocol, considered spontaneous cures (P less than 0.0001). Adverse effects of praziquantel were transient and included nausea and vomiting (15%), vertigo (12%), hepatomegaly (4.5%), headache (1.5%), rash (1.5%), and hypotension (1.5%). Of 20 patients who received placebo, 1 (5%) developed transient skin rash, fever, and chills. Clinically minor and transient, but statistically significant, changes in hemoglobin, total protein in serum, and levels of uric acid, cholesterol, and bilirubin in serum were noted. Results of this study showed that praziquantel is safe, well tolerated, and effective and should be considered as the drug of choice for treatment of clonorchiasis. In moderate infections, a second course of praziquantel therapy may be necessary to eliminate infection.

When larvae of C. sinensis reach the biliary system and mature, the flukes provoke pathological changes, both as a result of local trauma and of toxic irritation. The appearances vary with duration and severity of the infestation, but they are sufficiently distinctive and characteristic to allow a classification into four phases as follows; 1st phase, desquamation of epithelial cells, 2nd phase, hyperplasia and desquamation of epithelial cells, 3rd phase, hyperplasia and desquamation of epithelial cells, and adenomatous tissue formation, and 4th phase, marked proliferation of the periductal connective tissue with scattered abortive acini of epithelial cells and fibrosis of the wall of the bile duct. The onset of symptoms and signs is at times gradual, at times sudden. Chill and fever up to 40 degrees C occur during the acute stage, i.e. the period less than a month after parasite invasion. And a few weeks later, the chronic stage follows with the classical clinical features. In general, symptoms and signs can be classified as follows: mild, essentially symptomless, progressive, with irregular appetite, gastrointestinal disturbances, oedema, hepatomegaly, etc., and severe, with a syndrome associated with portal cirrhosis and hypertension. Pathogenic changes and complications are generally restricted to foci, but may eventually affect the whole liver. Calculi, acute suppurative cholangitis, recurrent pyogenic cholangitis, cholecystitis, hepatitis, and acute pancreatitis are important complications. Carcinoma of the liver is often found in association with clonorchiasis, too.

We review asymptomatic splenomegaly in Indochinese refugees and provide recommendations for evaluation of the problem. Prevalence of splenomegaly in newly arrived Indochinese refugees was 2.5%, three times more prevalent in the Hmong than in the non-Hmong refugees. Male Hmong refugees aged 15 to 29 years had the highest prevalence (10%). For the 50 Hmong refugees studied, there was no evidence that their splenomegaly was caused by clonorchiasis, schistosomiasis, tuberculosis, syphillis, lymphoma, tropical splenomegaly syndrome, or clinical malaria. Cases were more likely to have hepatomegaly, hepatitis B surface antigen positivity, and a low mean corpuscular volume than a reference population of Hmong refugees. Malaria antibody titers were elevated in all but one of the 41 cases (98%) tested.

Hypereosinophilic syndrome may cause eosinophil-related tissue damage to various organs. The purpose of this paper is to describe sonographic findings in 13 patients with hypereosinophilia in whom the liver was involved. The diagnosis in these 13 patients was based on liver biopsy in seven patients with bone marrow biopsy in six patients. Eight patients had hypereosinophilic syndrome and five patients had clonorchiasis. All 13 patients had mild to marked hepatomegaly. Seven of 13 patients showed multiple round or oval hypoechoic (n = 6) or variably echogenic (n = 1) lesions measuring 1 to 2 cm with poorly defined margins in both lobes of the liver. Four patients had one or two hypoechoic lesions 3 to 4 cm in size, with geographic pattern and poorly defined margins. Two patients showed diffuse hepatomegaly with increased parenchymal echogenicity. The number of lesions and the extent of diffuse lesions seem to be proportional to the degree of eosinophilia. Hypereosinophilia may produce multiple small focal hepatic lesions or diffuse segmental or lobar echogenic lesions simulating primary or metastatic tumor of the liver.

The authors reported a case of niclofolan intoxication occurred during the trial of clonorchiasis treatment. The case, a 15 years old Korean schoolboy, took niclofolan(Bilevon(R)) of total 473 mg(11 mg/kg) in 11 divided doses during 20 days. And the case suffered from neurologic symptoms such as severe headache, dizziness, nausea, vomiting, blurred vision, papilledema, retinal hemorrhage, an epsiode of seizure attack and elevated intracranial pressure, and hepatotoxic symptoms such as hepatomegaly, increased serum transaminases, and shoulder pain, excessive sweating and weight loss. Therapy was concentrated to the management of the elevated intracranial pressure. Hepatotoxic manifestations subsided within one month. The clinical signs related to elevated intracranial pressure persisted two months. Body weight regained after 2 months. And the symptoms of headache, dizziness and vomiting were complained intermittently until 4 months after onset. However, no subsequent clinical problems related with this episode has been noted until this record.
