Özet
Amaç: Visseral leishmaniasis (VL) Türkiye'nin de içinde bulunduğu Akdeniz ülkelerinde yaygın olarak görülür ve endemik bölgelerde çocuklar yetişkinlere göre daha büyük risk altındadırlar. VL hastalarında serolojik testler tanı ve/veya izlem açısından hassas olarak kabul edilmektedir. Bu çalışmanın amacı, Türkiye'de çocukluk çağı VL izlemi açısından serolojinin yararlılığını değerlendirmektir. Yöntemler: VL olduğu parazitolojik olarak doğrulanan yirmi çocuktan alınan serumlar IFAT ve ELISA testleriyle çalışıldı. Hastalar; tedavi süresince ve tedavi sonrasında (aralık: 20–500 gün) serolojik ve klinik olarak izlendi. Tüm VL hastaları meglumin antimonat ile tedavi edildi. Bulgular: Başarıyla tedavi edilen VL hastalarında anti-Leishmania antikorlarında keskin bir düşüş, nüks olan üç hastada ise antikorlarda artış tespit edildi. Anlamlı düşük değerler her iki serolojik teknikle tedavi sonrasında gözlendi. Tedavi öncesi ve sonrası ortalama ELISA OD değerleri: sırasıyla 0.78±0.36 (0.26-1.76) ve 0.38±0.24 (0.09-0.83) (p<0.001) idi ve tedavi öncesi ve sonrası (log10 transformed titers) IFAT ortalama değerleri ise sırasıyla 3.02±0.90 (1.81-4.51) ve 2.16±0.75 (1.20-3.90) (p<0.001) olarak saptandı. Sonuç: ELISA ve IFAT testleri; sadece tanı için değil aynı zamanda hızlı ve invaziv olmayan teknikler olarak Çocuk visseral leishmaniasis ilaç tedavisi izleminde de değerlidir.

Objective: Visceral leishmaniasis (VL) is endemic in all Mediterranean countries including Turkey, and children are at greater risk than adults in endemic areas. In VL patients, serological assays are considered to be sensitive for the diagnosis and/or follow up. The aim of this study was to assess the usefulness of serology for following up of childhood VL in Turkey. Methods: Sera obtained from twenty parasitologically confirmed children with VL were tested using IFAT and ELISA. The patients were monitored clinically and serologically (range: 20-500 days) during and after treatment. All VL patients were treated with meglumine antimonate. Results: Anti-Leishmania antibodies in successfully treated VL patients showed a steep decline but, in three patients who had relapsed, an increase was detected. Significantly lower values were observed after treatment with both serological techniques. Mean ELISA optical density values before and after treatment were: 0.78±0.36 (0.26-1.76) and 0.38±0.24 (0.09-0.83) respectively, (p<0.001) and mean IFAT values (log10 transformed titers) before and after treatment were: 3.02±0.90 (1.81-4.51) and 2.16±0.75 (1.20-3.90) respectively, (p<0.001). Conclusion: ELISA and IFAT are valuable not only for diagnosis but also for monitoring of drug therapy in childhood visceral leishmaniasis as rapid and non-invasive techniques.
