Comparison of microscopic examination, rK39, and PCR for visceral leishmaniasis diagnosis in Turkey.

The laboratory diagnosis of visceral leishmaniasis is based on microscopic examination, culture, serological tests, and molecular methods. In this study, we examined 50 blood specimens from suspected visceral leishmaniasis patients by microscopic examination, recombinant antigen dipstick test (rK39), and polymerase chain reaction (PCR) in the University of Cukurova, Faculty of Medicine, Parasitology Department in Turkey. We calculated the sensitivity-specificity and positive-negative predictive values for these diagnostic tests. We found that positive predictive value of microscopy examination, rK39 dipstick test, and PCR were 20%, 24%, and 58% for visceral leishmaniasis, respectively. When we compared polymerase chain reaction, recombinant antigen dipstick test, and microscopic examination for visceral leishmaniasis diagnosis, the polymerase chain reaction is more sensitive (100%) than recombinant antigen dipstick test and microscopy examination.

[Cystic echinococcosis in Turkey from 2001-2005]. / Türkiye'de 2001-2005 Yillari Arasinda Kistik Ekinokokkozis.

Cystic echinococcosis (CE) caused by the metacestode form of Echinococcus granulosus is a major public health problem especially in animal-raising regions of the world. In the present study, CE cases were determined during 2001-2005 by investigating different hospital and health directorship documents and Health Ministry documents, retrospectively. Our results show that there were 2534 (13.13%) cases in the Marmara region; 2114 (16.94%), in the Aegean region; 2578 (16.09%), Mediterranean region; 5404 (38.57%), in the Middle Anatolian region; 428 (5.70%), in the Black Sea region; 844 (6.80%), in the eastern Anatolian region; and 887 (2.75%), in the southeastern Anatolian region making a total of 14,789 CE cases. Finally, it has been determined that the patients were hospitalized for a total of 149,464 days.
