Abstract

At present, more than 500,000 foreigner workers, most of them from Asian countries with high parasitic infection rates, are working in Korea. Since investigation into the prevalence of parasitic infections in foreigner workers has not yet been conducted in Korea, the present study was performed to determine the parasitic infection status of foreigner workers living in Cheonan City, Chungcheongnam-do (Chungnam Province) and to plan, on that basis, effective control measures. From October to December 2013, the parasitic infection status of 231 foreigner workers employed at selected Cheonan-si small businesses was investigated by both stool examination and ELISA. A total of 60 individuals (26.0%) were found to be infected with parasites. The stool examination detected 14 positive cases (6.1%), and ELISA revealed 50 positive people (21.6%), for at least a kind of parasitic disease. The most common infection was cysticercosis (8.7%), followed by toxocariasis (7.8%) and clonorchiasis (7.4%). Since it was proved that parasitic infections were prevalent among foreigner workers living in Cheonan City, more comprehensive study is urgently needed in order to understand the nationwide status of parasitic infections in foreigner workers.

House Dust Mite Allergens in Domestic Homes in Cheonan, Korea: Hae-Seon Nam, Robert Siebers, Sun-Hwa Lee, Joon-Soo Park, Yong-Bae Kim, Young-Jin Choi, Sang-Han Lee, Julian Crane; Korean J Parasitol 2008;46(3):187-189.

Abstract

House dust mites produce inhalant allergens of importance to allergic patients. We measured the major group 1 allergens, Der p 1 and Der f 1, from the house dust mites Dermatophagoides pteronyssinus and Dermatophagoides farina, respectively in 100 randomly selected domestic homes from Cheonan, Korea. Dust samples were collected by vacuuming from the living room floor and 1 mattress in each home. Der p 1 and Der f 1 were measured by double monoclonal ELISA. Der p 1 levels were very low, with geometric mean levels for floors and mattresses being 0.11 ?g/g (range: 0.01-4.05) and 0.14 ?g/g (range: 0.01-30.0), respectively. Corresponding levels of Der f 1 were higher, 7.46 ?g/g (range: 0.01-262.9) and 10.2 ?g/g (range: 0.01-230.9) for floors and mattresses, respectively. D. farinae appears to be the dominant house dust mite in Cheonan.

Validity of MAST-CLA for diagnosis of arthropod allergy using receiver operating characteristic (ROC) analysis: Joon-Soo Park, Hae-Seon Nam, Yong-Bae Kim, Young-Jin Choi, Sang-Han Lee, Sung-Ho Kim; Korean J Parasitol 2007;45(3):239-243.

Abstract
PDF

Many allergists are currently focusing on the development of new diagnostic tools, and are attempting to improve both the sensitivity and specificity. A multiple allergen simultaneous test-chemiluminescent assay (MAST-CLA) is one of the most popular diagnostic tools used in the Republic of Korea. However, there remains controversy among allergists with regard to the cut-off point for a positive result. The present study was conducted in order to determine the validity of MAST-CLA as compared with that of the skin prick test, with particular emphasis on arthropod allergens, on the basis of percentage agreement rates and κ-values, and also to suggest the optimal positive cut-off points using receiver operating characteristic (ROC) curves. The study was conducted with 97 subjects (54 men, 43 women). Optimal individual cut-off points were calculated as follows; class II for Dermatophagoides farinae, class I for Dermatophagoides pteronyssinus, and trace for a cockroach mix. These findings suggest that attempting to apply optimal individual cut-off points will be a good way of improving diagnostic tests, particularly MAST-CLA.

Prevalence of arthropod antibodies in Korean patients with allergic rhinitis: Kyu-Yoon Hwang, Joon-Soo Park, Hyun-Cheol Ahn, Hae-Seon Nam; Korean J Parasitol 2001;39(2):197-199.

Abstract
PDF

Arthropod antigens are main causative agents which induce allergic reponses in humans. However, little information is known about the prevalence of specific arthropod allergens in Koreans with allergic diseases. The current study was designed to determine the positive rates of arthropod antibodies by the Korean inhalant panel of MAST-CLA. One hundred sixty patients, who were diagnosed with allergic rhinitis from an out-patient center at the Soonchunhyang University Chunan Hospital, were studied between August 1998 to July 2000. The overall positive rate, at least more than one specific antibody of arthropods such as Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), and cockroach mix (Cm), was 46.9%. Each positive rate of Df, Dp, and Cm was 45.0%, 43.1%, and 8.8%, respectively. A significant agreement among arthropod allergens was observed (Df and Dp: 95.6%, Kappa = 0.911, P < 0.001). Our data supported the fact that arthropods were the most common allergens in Korean patients with allergic rhinitis; however, the MAST-CLA should be modified to increase specificity of arthropod allergens.

Infection status with trematode metacercariae in pond smelts, Hypomesus olidus: Hae-Seon Nam, Woon-Mok Sohn; Korean J Parasitol 2000;38(1):37-39.
Published online March 31, 2000; DOI: https://doi.org/10.3347/kjp.2000.38.1.37

Abstract

Many Koreans usually eat raw pond smelts, Hypomesus olidus, in the winter. This study was performed to evaluate the infection status with trematode metacercariae in pond smelts from January 1998 through February 1999. Among 1,305 fish collected, 459 were purchased from wholesale dealers in Chinchon-gun, Chungchongbuk-do, and the rest of them were caught with a casting net in Soyangho (Lake), Taehoman (Bay) and Paekkokchosuchi (Pond). Seven species of trematode metacercariae including two unidentified ones were detected from 1,305 pond smelts. The number of detected trematode metacercariae according to the species are as follow: Clonorchis sinensis 8, Holostephanus nipponicus 7, Cyathocotyle orientalis 24, Diplostomum sp. 14, and Metorchis orientalis 7. From the above results, it was confirmed that H. olidus plays a role as the second intermediate host of some kinds of trematode including C. sinensis in Korea. Our report shows possible clonorchiasis caused by eating raw pond smelts.
