Abstract

In recent years an increase in the rate of detection of HIV and Leishmania co-infections has been reported from many countries especially countries in Southern Europe. Visceral leishmaniasis (VL) is sporadically detected in some parts of Turkey. Although the natural transmission is via sandfly bites, VL may be transmitted by needle sharing of intravenous drug addicts or by blood transfusion in HIV/AIDS patients. The aim of this study was to investigate the presence of specific antibodies against Leishmania infantum, which is the causative agent of VL, in the sera of HIV/AIDS patients. A total of 79 HIV/AIDS patients (61 male, 18 female; mean age: 30±2 years) with confirmed diagnosis by HIV Reference Laboratory of Refik Saydam Hygiene Center between the years of 2004-2006, were included in the study. L.infantum antibodies were searched by fast agglutination screening test (FAST), direct agglutination test (DAT), indirect immunofluorescent antibody test (IFAT) and rK39 dipstick assay. Only one serum sample (1.2%) was found to be seropositive by all of the serological tests (>1/100 by FAST, 1/3200 by DAT, 1/256 by IFAT, and specific bands for L.infantum by rK39 dipstick test), while the remaining samples were negative with all of the methods. The seropositive serum was from a 49 years-old heterosexual male, living on the Mediterranean cost and has had acquired the HIV infection by sexual contact. He has no history of intravenous drug use but he had experienced blood transfusion. Since the seropositive serum sample was collected 2-3 weeks after the transfusion, the transmission of L.infantum was thought to be during blood transfusion, however it could also be acquired via a previous sandfly bite. In conclusion although the rate of L.infantum seropositivity was low in HIV/AIDS patients in our study, the possibility of HN/Leishmania co-infections should be considered.

Özet

Son yıllarda birçok ülkede ve özellikle de Güney Avrupa ülkelerinde HIV ve Leishmania koenfeksiyonlarına rastlanma sıklığında artış olduğu bildirilmektedir. Ülkemizin bazı bölgelerinde sporadik olarak görülen visseral leishmaniasis (VL), doğal olarak tatarcık ısırığı ile bulaşmakla birlikte HIV/AlDS'li hastalarda bulaş, damariçi uyuşturucu bağımlılarında enjektörlerin paylaşılması ve/veya kan transfüzyonu ile de gerçekleşebilmektedir. Bu çalışmada, HIV/AlDS'li hastalarda VL etkeni olan Leishmania infantum'a özgül antikor varlığının araştırılması amaçlanmıştır. Çalışmaya, 2004-2006 yılları arasında Refik Saydam Hıfzıssıhha Merkezi Başkanlığı, HIV Referans Laboratuvarı'nda HIV/AIDS tanısı doğrulanan 79 hastaya (61 erkek, 18 kadın; yaş ortalaması: 30±2 yıl) ait serum örneği dahil edilmiştir. Tüm örneklerde L.infantum antikorları, hızlı aglütinasyon tarama testi (FAST), direk aglütinasyon testi (DAT), indirek floresan antikor testi (IFAT) ve rK39 hızlı tanı testi (dipstick assay) ile araştırılmıştır. Örneklerin sadece birisinde (%1.2) tüm serolojik yöntemlerle pozitiflik saptanmış (FAST ile >1/100, DAT ile 1/3200, IFAT ile 1/256, rK39 testinde L.infantum'a özgül bantlar), diğer örneklerin tamamı tüm yöntemlerle negatif olarak bulunmuştur. Seropozitif örneğin Akdeniz kıyı ilinde yaşayan 49 yaşında heteroseksüel bir erkeğe ait olduğu, HIV enfeksiyonunu cinsel temas yoluyla kazandığı, intravenöz ilaç kullanım öyküsünün bulunmadığı ancak kan transfüzyonu yapıldığı belirlenmiştir. Hastanın seropozitiflik saptanan serumunun kan transfüzyonundan 2-3 hafta sonra alındığı tespit edilmiş ve L.infantum bulaşının tatarcık ısırığı ile olabileceği gibi transfüzyon ile de olabileceği düşünülmüştür. Sonuç olarak, HIV/AlDS'li hastalarda L.infantum seropozitifliğinin düşük bulunmasına rağmen HIV/ Leishmania koenfeksiyonlarının akılda tutulmasının yararlı olduğu kanısına varılmıştır.
