ABSTRACT

Objective To investigate epidemiological and clinical features of patients with clonorchiasis sinensis infection. Methods The epidemiological, clinical, laboratory and treatment data of clonorchiasis patients in Department of Infectious Diseases, Second Affiliated Hospital, Harbin Medical University from 2002 to 2004 were retrospectively analyzed. Results Sixty-eight point two percent patients had a history of eating raw freshwater fish and shrimp. Patients with occupations as cook, fish stock man, fishing man and fishmonger accounted for 22.6%. The transmission route was not clear in 9.1% of patients. The common clinical manifestations were abdominal pain (60.3%), fatigue (52.3%), diarrhea (33.0%), anorexia (69.3%), jaundice (23.9%), hepatomegaly (59.1%), splenomegaly (8.0%), dizziness (20.9%), fever (5.7%) and biliary colic (14.8%). Twenty-eight point four percent were asymptomatic. Other findings included liver dysfunction (70.4 %) and eosinophile granulocyteosis(69.3 %). Negative rate of stool egg of clonorchis sinensis after treatment with praziquantel or albendazole was 91.9% or 86.5%, respectively. There was no significant difference between the two groups ( χ2 = 0.561, P = 0.454). Conclusions Clinical manifestations of patients with clonorchiasis sinensis are complicated and often accompanied with liver dysfunction. Clonorchiasis sinensis is often misdiagnosed and should be paid much attention.
