Abstract

Objective: Alveolar echinococcosis (AE) is one of the most lethal parasitic zoonoses in the Northern Hemisphere, and early serological detection is important to start treatment and to improve survival. A total of 50 sera samples of patients diagnosed as having various diseases were examined for by two different serological diagnostic methods. Methods: Em2-Em18 ELISA (Bordier Affinity Products, Crissier, Switzerland) and Echinococcus Western Blot immünoglobulin G (IgG) (LDBIO Diagnostics, Lyon, France) were used for analyisis. Results: A high titer of antibodies was found in 9 of 10 patients diagnosed as having AE with Em2-Em18 ELISA, in 2 of 21 patients with cystic echinococcosis, in 1 of 2 patients with fascioliasis and in 1 patient with chronic hepatitis. The Echinococcus Western Blot IgG test, used as a confirmatory test, showed IgG antibody in 85.7% (18/21) of patients with CE, while all serum samples of 10 patients with AE were evaluated as positive. This method yielded an incorrect diagnosis in the patient with chronic hepatitis and in the patient with granulomatous inflammation with caseification. Samples taken from patients with liver-related diseases and other parasitic-related diseases were found to be negative. Conclusion: The serological methods used in the study were found to be important in the early diagnosis of alveolar echinococcosis in the endemic areas, since it could be used in sero-epidemiological studies.

Özet

Amaç: Alveolar ekinokokkoz (AE) kuzey yarım kürenin ölümcül parazitik zoonozlarından biri olup erken tanı konulması vetedaviye başlanması hayatta kalma olasılığını arttırmaktadır. Bu çalışmada, çeşitli hastalıklardan tanı almış 50 hastanın serumörneği iki farklı serolojik tanı yöntemi ile değerlendirilmiştir.Yöntemler: Çalışmada, Em2-Em18 ELISA (Bordier Affinity Products, Crissier, Switzerland) ve Echinococcus Western Blotimmünoglobulin G (IgG) (LDBIO Diagnostics, Lyon, France) yöntemleri kullanılmıştır.Bulgular: Em2-Em18 ELISA ile patolojik olarak AE tanılı 10 hastanın dokuzunda, kistik ekinokokkoz (KE) tanılı 21 hastanınikisinde, 2 fascioliasis tanılı hastanın birinde ve bir kronik hepatitli hastada yüksek titrede antikor saptanmıştır. Doğrulayıcı testolarak kullanılan Echinococcus Western Blot IgG testi ile 10 AE hasta serumunun tamamı pozitif olarak değerlendirilirken KEhastalarının %85,7’sinde (18/21) IgG antikoru saptanmıştır. Hepatit hastasında ve kazeifiye granülomatöz enflamasyon görülenhastada ise bu yöntemle yanlış tanıya rastlanmıştır. Karaciğer ile ilgili hastalıkları olan ve diğer paraziter kaynaklı hastalıkları olanhastalardan alınan örnekler ise negatif olarak saptanmıştır.Sonuç: Çalışmada uygulanan serolojik yöntemler, endemik bölgelerde özellikle AE’nin erken tanısında ve sero-epidemiyolojikçalışmalarda kullanılabilirlik açısından önemli bulunmuştur.
