[Studies on paragonimiasis in Ko-Hoong County, Korea (Report 1.): An epidemiologic survey for human paragonimiasis by the use of intradermal screening test]

Authors carried out the survey for human paragonimiasis in Ko-Hoong County, Chun-Nam Province, Korea from July to September 1964 by the use of intradermal screening test with Veronal buffered saline antigen. Eight myuns (village) out of 13 myuns of this county were selected for the survey, regarding balanced selection. The number of 2,916 primary school children of high class and 764 residents of all age groups in these areas were examined (total 3,680; male 1,961; female 1,719). The following results were obtained in this survey. 1) As a whole, 20.1 per cent of the examiners showed positive reaction, with sexual difference of 20.9 per cent in male and 19.1 per cent in female. 2) In regional differences of positive rate, the highest rate(50.1 per cent) was showed at Po-Doo myun and lowest rate(3.6 per cent) was showed at Do-Yang myun. 3) In age group, the highest positive rate was showed in 16 to 20 age group (46.7 per cent). 4) In regional comparison of paragonimiasis infectivity of whole nation (province and county), Ko-Hoong County as nearly same as the Hea-Nam County, Chun-Nam Province follows next of Cheju Province, the highest prevalance area of paragonimiasis in Korea, in concentration of prevalence of paragonimiasis.

Retroperitoneal paragonimiasis: a case of ectopic paragonimiasis presenting as periureteral masses.

We describe a case of retroperitoneal paragonimiasis presenting as periureteral masses. CT showed a conglomerate of enhancing nodules with subtle low attenuation in the center at the left iliac fossa and clustered, ring-like, enhancing lesions at the left renal hilum. When a retroperitoneal conglomerate of ring-like, enhancing lesions in association with pleuropulmonary disease suggestive of paragonimiasis can be found in endemic regions or in migrants from those regions, one may expect ectopic-retroperitoneal paragonimiasis.

Pulmonary paragonimiasis misdiagnosed as tuberculosis: with special references on paragonimiasis.

The diagnosis of tuberculosis by X-ray radiogram is often confused with pulmonary carcinoma, bacillary and parasitic infections, and chronic mycosis. A case of pulmonary paragonimiasis misdiagnosed as tuberculosis by X-ray radiogram is reported. With this case, the smears of sputum were rechecked by an inspection technician's discernment, and Paragonimus eggs along with numerous eosinophils and Charcot-Leyden crystals were detected. In suspected cases of tuberculosis, a history of crab-eating plus sputum examinations, image findings, and serodiagnosis are necessary to rule out paragonimiasis.

Endemic human paragonimiasis in Equatorial Guinea. Detection of the existence of endemic human paragonimiasis in Equatorial Guinea as a result of an integrated sanitary programme.

Between February and April 1990 the first five cases of human paragonimiasis, tentatively due to Paragonimus africanus, have been detected in Equatorial Guinea, thanks to the normal activities of the National Schistosomiasis Project and its coordination with the National Tuberculosis Project.

An epidemiological study of pleuropulmonary paragonimiasis among pupils in the peri-urban zone of Kumba town, Meme Division, Cameroon.

BACKGROUND: Paragonimiasis have previously been reported in two zones of the Southwest Province of Cameroon including the Kupe mountain and Mundani foci. The aim of this study was to investigate the presence and epidemiology of paragonimiasis in the peri-urban zone of Kumba, Meme Division, located about 50 km away from the Kupe mountain focus. METHODS: Pupils of several government primary schools in 5 villages around Kumba underwent both parasitologic and clinical investigations in search of signs and symptoms of paragonimiasis. Mycobacterium tuberculosis was also searched for in the differential diagnosis. Freshwater crabs from neighbouring streams in the five villages were dissected in search of paragonimus metacercariae. RESULTS: Out of a total of 1482 pupils examined in all five villages, 309 individuals (147 males and 162 females) were recruited for this study based on the presence of one or more signs or symptoms of paragonimiasis. Eggs of Paragonimus africanus were found in stools and/or sputum of pupils from all five villages, giving an overall paragonimus prevalence of 2.56%. There was no significant difference in the disease prevalence between the villages (Chi2 = 8.36, P = 0.08). The prevalence of Paragonimus africanus eggs amongst pupils with symptoms of paragonimiasis was 12.3% (38 of 309). Males were infected more than females (17.0% versus 8.0%), but the difference was not significant (Chi2 = 5.76, P = 0.16). All the 38 paragonimus egg positive subjects presented with cough, 23 (60.53%) complained of chest pain while 16 (42.11%) had haemoptysis. Stool examinations also detected some intestinal parasites including Ascaris lumbricoides (29.45%), Trichuris trichiura (6.47%), Necator americanus (2.27%), Strongyloides stercoralis (1.62%), Enterobius vermicularis (0.65%), and Entamoeba histolytica (4.53%). No case of M. tuberculosis was noted. Out of a total of 85 dissected crabs (Sudanonautes africanus), 6.02 % were infected with paragonimus metacercariae. CONCLUSION: In addition to the two previously described paragonimiasis foci of Kupe mountain and Mundani, the identification of autochthonous cases of paragonimiasis in the peri-urban zone of Kumba town, makes the South West Province the most endemic zone of paragonimiasis in Cameroon at present.

[A case of Paragonimiasis westermani with pleural effusion eight months after migrating subcutaneous induration of the abdominal wall].

Patients with Paragonimiasis westermani show a typical ring form or nodular shadow on chest X-ray, cough, sputum, and hemosputum. Recently, case reports of Paragonimiasis westermani, accompanied by pneumothorax and pleural effusion, as for Paragonimiasis miyazakii, have been increasing. Paragonimus westermani often causes an ectopic infection in various organs such as the peritoneal cavity, pleural cavity, pericardium, liver, adrenal gland and brain. Cutaneous paragonimiasis is considered one of the typical forms of ectopic infection in its earlier phase, but a few unexpected cases of cutaneous Paragonimiasis westermani have also been reported. A 68-year old man, who had never eaten fresh-water crab or raw sliced meat of wild boar, noticed subcutaneous induration of the abdominal wall. The induration had been gradually moving upwards and to the right from the infraumbilical region for over 20 days, and then disappeared at the right upper lateral abdominal wall. Eight months later, he developed severe pain in the right lower chest, and a chest X-ray showed right pleural effusion. Laboratory examinations revealed eosinophilia (WBC 3940/mm3, eosinophil 9%), elevated ESR, and an elevated serum total IgE level (5517 IU/ml). Ouchterlony's double diffusion test performed with the patient's serum in agarose showed strong bands toward Paragonimus westermani antigen, compared to Paragonimus miyazakii antigen. Immunoelectrophoresis with the patient's serum showed specific bands toward Paragonimus westermani antigen. This patient was finally diagnosed as having Paragonimiasis westermani infection, and he responded to praziquantel administration. The clinical course of this patient appears to be rare in cases of Paragonimiasis westermani infection. The clinical course of this case resembled some cases of Paragonimiasis miyazakii infection.(ABSTRACT TRUNCATED AT 250 WORDS)

Development of enzyme-linked immunosorbent assay for serodiagnosis of human paragonimiasis.

BACKGROUND & OBJECTIVE: Although human paragonimiasis is known to occur in Manipur and Arunachal Pradesh, there is no indigenous immunodiagnostic test available in India. Sputum examination for detection of eggs is less sensitive method for diagnosis of paragonimiasis and unfortunately, the eggs are not always present in the sputum of infected individuals. Due to overlapping clinical manifestations and similarities between X-ray picture in pulmonary paragonimiasis and pulmonary tuberculosis, chances of diagnostic confusion can increase. Therefore, the objective of this study was to develop an ELISA test indigenously for diagnosis of paragonimiasis. METHODS: Somatic (S) and excretory-secretory (ES) antigens of adult trematodes belonging to genus Paragonimus were prepared. Serum samples were collected from 22 confirmed patients of paragonimiasis and from five groups of negative controls. The cut-off points for both types of antigens were calculated using receiver operating characteristic (ROC) curve analysis. The sensitivity, specificity, predictive values and efficiency of the ELISA tests were also calculated. RESULTS: IgG-ELISA test using either S or ES antigens were 100 per cent sensitive yet the utility of S antigen for diagnosis of paragonimiasis seemed to be less reliable because of low specificity (91.3%). On the other hand, ES antigen was more reliable with 100 per cent specificity as no false positive cases were recorded. INTERPRETATION & CONCLUSION: ES antigen can be effectively used for screening large populations for paragonimiasis. In areas where both paragonimiasis and tuberculosis are endemic, suspected subjects should be screened for both the diseases because of chance of mistaken diagnosis. Correct diagnosis will avoid unnecessary costly treatment.
