| Popis: | We report two cases of Paragonimus westermani infection in a Chinese family in Japan. A 41-year-old husband and his 40-year-old wife were infected with P. westermani after consuming a homemade Chinese traditional "Drunken Crab." They were a family with two children who had lived in Japan for 19 years. The crabs were Eriocheir japonica sent from the Kyusyu area that they had pickled at home with soy sauce and Chinese liquor for 5 days. Their children did not eat any of the crabs. One month after consuming the crabs, the husband came to our outpatient clinic with fever and chest pain and his wife also presented with a persistent cough. Both patients had a high peripheral blood eosinophil count (husband:18,900/μL, wife:10,600/μL) with pulmonary effusion, nodular shadow, and pneumothorax in chest X-ray findings. Paragonimiasis was suspected from the episode of consuming the crabs. No parasite eggs were seen in their sputum and stool samples. A multiple-dot ELISA was performed with the sera to screen for parasitic infections, but the result was only weakly positive for P. westermani antigen in the husband and a slightly positive reaction in the wife. The diagnosis of P. westermani was achieved with the double diffusion Ouchterlony method using P. westermani antigen and P. miyazakii antigen. Praziquantel administration for three days improved the symptoms in both patients. The Ouchterlony method proved useful in diagnosing paragonimiasis in these cases. |
