We report a Laotian patient with pleural paragonimiasis who did not have the usual diagnostic triad for this parasitic disease. He did not have chronic hemoptysis (considered by many to be an "invariable" finding), there were no pulmonary infiltrations, and stool and sputum examinations did not yield Paragonimus ova. The diagnosis was made on the basis of ova found in the pleural fluid. Paragonimiasis pleural effusion did not resolve with bithionol, the drug of choice for pulmonary paragonimiasis, and, as a result, chest tube drainage was required. The difference between pleural paragonimiasis and pulmonary paragonimiasis is that the classic clinical presentation of the latter (hemoptysis, ova in sputum and stools, lung infiltration, etc.) requires an intrapulmonary location on the parasite. A search for ova in the pleural fluid may be the only diagnostic tool for patients suspected of pleural paragonimiasis. With the influx of Southeast Asia refugees, this case report may be of relevance to U.S. physicians involved in the care of patients in whom not all chronic pleuropulmonary diseases are tuberculous.

A Laotian immigrant with persistent cough and hemoptysis was found to have multiple small cavities on chest roentgenogram. Ova of the lung fluke Paragonimus westermani were found in the sputum, and the patient responded to bithionol therapy. Pulmonary paragonimiasis should be considered in the differential diagnosis of cavitary lung disease in Indochinese refugees entering the United States.

A survey was undertaken in the east district of Imphal valley of Manipur, India, using an intradermal test with saline extract of adult Paragonimus westermani as test antigen to find out the prevalence of paragonimiasis and some of the epidemiological factors attributable to it. A total of 3,467 individuals of both sexes aged five years and above were tested. A total of 2934 persons admitted eating crabs and among them 234 were found reactive to Paragonimus antigen. The prevalence rate observed was 6.7 per cent. The proportion of positive reactors (8.0%) among the crab eaters compared to 0.1 per cent among those who did not eat crabs was highly significant (P < 0.01). The difference in the prevalence rates in different age groups and different sexes was also found to be highly significant. The habit of eating raw and or undercooked crabs had significant correlation with skin reactivity. The intradermal test was found to be a good screening test for mass surveys due to its simplicity, low cost, high sensitivity and no known untoward reaction. Four persons among the skin positive reactors presented with cough, pain in the chest, recurrent haemoptysis as major clinical manifestations. Laboratory investigations revealed Paragonimus eggs in the sputum smears, raised erythrocyte sedimentation rate, and high absolute eosinophil count in their blood. Praziquantel, the drug of choice was given at a dose of 25 mg per kg body weight 3 times a day for three consecutive days to each patient for a cure.

The clinical epidemiology of pulmonary paragonimiasis and tuberculosis was investigated in a known endemic municipality of Sorsogon, Philippines. Records of diagnosed tuberculosis patients on treatment and follow up at the local Rural Health Unit over a two year period from 1993 to 1994 were reviewed to provide an overview of pulmonary tuberculosis in the area, specifically to describe the population at risk, the basis for diagnosis and the proportion of case notification who were sputum negative. Patients from the same group of individuals as well as undiagnosed tuberculosis patients with productive cough, fever with chest and/or back pain, or hemoptysis were examined to look into clinical manifestations, duration of symptoms, history of crab-eating and sputum examination results for acid-fast bacilli and Paragonimus. There was difficulty in determining the number of non-responders as the records did not have any provision for the recording of such. Annual tuberculosis case notification rates for the two years (374 and 401 per 100,000 population) were higher than the national figure in 1991 (325 per 100,000 population) indicating that tuberculosis is still a major health problem in the area and tuberculosis control efforts may have to be more aggressive to better contain the disease. Twenty-six out of 160 individuals surveyed were sputum smear positive for Paragonimus. Paragonimiasis rates were not significantly different in the two groups (15.6% vs 16.9%, respectively) indicating that there is a need for routine sputum examination for Paragonimus which is not available at present. Only six patients surveyed were sputum smear positive for acid-fast bacilli. A high index of suspicion is necessary to diagnose paragonimiasis and to be able to differentiate it from tuberculosis. The diagnosis may be suggested by a patient's place of origin being a known endemic area, a long period of chronic cough and the habit of eating raw or insufficiently cooked crabs or crayfish. Laboratories in endemic areas should have the capacity to differentiate between the two infections by being able to provide the routine laboratory procedures necessary for definitive diagnosis and treatment.

Paragonimiasis is a helminthic disease of carnivorous animals. Man is infected accidentally. It has a worldwide distribution but is mainly encountered in Southeast Asia, particularly in Korea. Other endemic areas include Africa and South America. Cerebral paragonimiasis is not rare, but pleuropulmonary manifestations are the most prevalent. They include hemoptysis (frequently rusty-colored), unilateral or bilateral pleural effusions, and pulmonary infiltrates or cavities. This constellation of symptoms often mimics those of tuberculosis. Cerebral and lung involvement has recently been investigated by CT-scan and NMR. The diagnosis is based on the identification of parasite eggs in sputum or feces, and on ELISA serology. The treatment of choice is praziquantel.

A 77-year-old woman was admitted to our hospital with hemoptysis and weight loss. She had eaten 15 raw freshwater crabs about 5 months before the onset of her clinical symptoms. Chest X-ray films obtained on the first admission showed left pleural effusion. After 1 week of chemotherapy with SBTPC, the pleural effusion disappeared. Two months later, the patient was re-admitted with recurrent hemoptysis. Chest X-ray films showed a solitary nodular lesion in the right lung. Eosinophilia and increased serum IgE levels were detected. The solitary nodular lesion moved from the middle to upper field of the right lung during the patient's 3-week stay in the hospital. Serologic tests yielded a conclusive diagnosis of Paragonimiasis miyazakii infection. Praziquantel administration relieved the patient's symptoms.

We encountered seven cases of pulmonary paragonimiasis. All patients were adult males and 6 of 7 cases were over 50-year-old. Except for one case of chronic pleural empyema, 6 patients were referred to the department of surgery because of having a mass lesion on chest roentgenography which was indistinguishable from malignancy. Although 3 patients had mild hemoptysis, none of them showed classical rusty sputum. Only one patient had high level of eosinophilia, whereas others showed normal or marginal level of eosinophilia. Paragonimus eggs were detected in transbronchial lung biopsy specimens from 4 patients. All patients' sera were positive for Paragonimus-specific IgG antibody by immunodiagnosis. Surgical option was undergone only for one patient with chronic pleural empyema which was not cured by repeated chemotherapy. In the present series, we could avoid surgical options due to an erroneous diagnosis. When a pulmonary mass lesion or empyema is detected in patients who live in paragonimiasis endemic areas, paragonimiasis should always be included in the different diagnosis of lung diseases.

Sin Ho is a district of the northern mountainous province of Lai Chau, Vietnam, where the people have the habit of eating undercooked crabs. A study on paragoniamiasis carried out from 1994 to 1995 with 1,642 persons in this endemic area, showed that the rate of eating raw-crab was 72.5%. Crab examination (Ranguna kimboiensis) showed an infection rate of Paragonimus metacercaria of 98.1%. With 624 stool samples examined by Kato technique, the infection rate of Paragonimus in humans was 6.4%. With 338 sputum samples examined by direct and centrifuge methods, the infection rate of Paragonimus was 7.4%. Most of the patients were children (63.2%). The infection rate of Paragonimus in dogs was 18.2 - 33.3%. Adult worms, collected from the dogs in the field and from the cats in laboratory, were identified as Paragonimus heterotremus. The main symptoms of Paragonimus patients were cough and hemoptysis (92%), discontinuously developed (96%), without fever (94%), chest pain (70%), pleural effusion (26%), neurogical symptoms (8%), eosinophilia (88.9%), nodular ring shadows in the lungs, as shown by chest X-ray examination and more in lower lobe, (76.2%). Paragonimiasis patients were treated by (a) Praziquantel 25 mg/kg/day x 3 days; the cure rate was 68.8%. (b) Praziquantel 50 mg/kg/day x 3 days; the cure rate was 75%.

Hemopytsis is commonly encountered in the daily practice of the pulmonary physician. Younger patients with normal chest x-rays frequently have acute or chronic bronchial disease accounting for their complaint. Occasionally parasitic disease is described as an unusual cause for a patient presenting with hemoptysis. Although pulmonary paragonimiasis is unusual in this country, because of the rapid growth in travel as well as immigration, physicians will need to be aware of this disorder.

Paragonimiasis is a zoonosis caused by adult trematodes of the Paragonimus genus. The infection in humans is a result of a complex transmission cycle that includes two obligate intermediate hosts, a snail and a crustacean or a crayfish, and a definitive mammalian host. It has been shown that 9 of the more than 40 species of Paragonimus described affect humans in over 39 countries in Asia, Africa and America. It is estimated that 20.7 million people have paragonimiasis and it is calculated that 195 million people are at risk of being infected. The illness usually is caused once the parasite has settled in the lung at the site of the main clinical symptoms: cough, thoracic pain and hemoptysis. The diagnosis of paragonimiasis is based on the patient's history, the parasitological findings (ova in sputum and in feces), and the result of radiological and immunological tests. In severe cases, the patient may suffer from life-threatening hemoptysis or pneumothorax. Currently, praziquantel is the drug of choice.
