Abstract

The aim of this retrospective study was to compare the results of indirect hemagglutination (IHA) and ELISA-IgG methods for the patients who were prediagnosed as hydatid cyst disease. Serum samples of 487 cases (301 female, 186 male; age range: 14-69 years) which have been sent to the Parasitology Laboratory of Refik Saydam Hygiene Center between the period of 2003 to 2005 were included to the study. Echinococcus granulosus specific antibodies were searched by commercial IHA (Fumouse Laboratories, France) and ELISA-IgG (r-Biopharm, Germany) kits. Of the serum samples, 284 (58.3%) were found negative, and 173 (35.5%) were found positive with both of the methods. Nineteen samples (3.9%) which were detected as negative by IHA, were found positive by ELISA. In 11 samples (2.3%) which were found negative by ELISA, agglutination reaction were observed at the titers of 1/160-1/1280 by IHA. The results were evaluated by Kappa statistical analysis with 95% confidence intervals and the results of IHA and ELISA tests showed high correlation (κ=0.88) by means of the serological diagnosis of hydatid disease. In evaluation of the cases whose sera were positive with both of the methods, no statistical differences was observed in terms of gender (χ2 =0.08, p=0.78), and the highest seropositivity (43.4%) rate was observed in the 40-56 years age group. As a result, although our data indicated a high correlation between ELISA and IHA methods, the use of these tests together will be favorable for the screening of suspected patients in terms of comparability and confidency, in routine laboratories which do not have economical limitations.

Özet

Bu retrospektif çalışmada, Ankara Refik Saydam Hıfzıssıhha Merkezi Başkanlığı Parazitoloji Laboratuvarı’na 2003-2005 yılları arasında gönderilen kist hidatik (KH) ön tanılı hastaların serumlarında indirek hemaglütinasyon testi (IHA) ve ELISA- IgG yöntemi ile alınan sonuçların karşılaştırılması amaçlanmıştır. Çalışmaya alınan 487 olgunun (301 kadın, 186 erkek; yaş aralığı: 14-69 yıl) serum örneğinde Echinococcus granulosus‘a özgül antikorlar, ticari IHA (Fumouse Laboratories, Fransa) ve ELISA- IgG (r-Biopharm, Almanya) kitleri ile çalışılmıştır. Örneklerin 284'ü (%58.3) her iki test ile de negatif, 173´ü (%35.5) ise her iki test ile de pozitif olarak bulunmuş; IHA ile negatif bulunan 19 (%3.9) örnek ELISA ile pozitif olarak saptanmıştır. ELISA ile negatif olarak bulunan 11 (%2.3) örnekte ise, IHA testinde 1/160-1/1280 titrelerde aglütinasyon gözlenmiştir. Kappa istatistiksel analizi ile 95% güvenilirlik aralığında, KH serolojik tanısında ELISA ve IHA testleri ile alınan sonuçlar arasındaki tutarlılığın çok yüksek olduğu bulunmuştur (κ=0.88). Çalışmamızda, her iki test ile de pozitif sonuç alınan olguların cinsiyet dağılımları arasında önemli bir fark saptanmamış (χ2 =0.08, p=0.78), en yüksek seropozitifliğin (%43.4) 40-59 yaş grubunda olduğu izlenmiştir. Sonuç olarak bulgularımız, IHA ve ELISA testleri arasındaki uyumun yüksek olduğunu göstermekle birlikte, rutin hasta taramalarında sonuçların karşılaştırılabilirliği ve güvenirliği açısından ekonomik kısıtlılığı olmayan laboratuvarlarda her iki yöntemin birlikte kullanılmasının uygun olacağı kanısına varılmıştır.
