None of the patients had any signs of BKVN on immunohistochemical staining of renal biopsy specimens.COnClusIOn: Failure to detect BKVN in this study may be because BKV causes gradual impairment of renal functions and the sample did not include patients frequently observed to have BKVN in the native kidney.

Abstract

OBJeCtIVe: Although BK virus nephropathy (BKVN) has mostly been reported to occur in transplanted kidneys, there has been a gradual increase in cases of BKVN in the native kidney. This study was directed towards investigating the incidence of BKVN in patients undergoing renal biopsy due to acute kidney injury (AKI) who were also immunosuppressed due to a condition other than organ transplantation.MAterIAl and MethOds: Out of the 1223 patients undergoing renal biopsy for various conditions between January 2001 and January 2013, 52 patients who underwent a biopsy for AKI and were immunosuppressed at the time of the biopsy were included into the study. After renal biopsies of all patients were reevaluated, all biopsy specimens were exposed to immunohistochemical staining for SV40 antibody. results: Of the 52 patients, 29 had primary glomerulonephritis, 18 had secondary glomerulonephritis and 5 had a malignancy. All patients except one case of acute lymphoblastic leukemia and one case of non-Hodgkin lymphoma were immunosuppressed due to immunosuppressive therapy. None of the patients had any signs of BKVN on immunohistochemical staining of renal biopsy specimens.COnClusIOn: Failure to detect BKVN in this study may be because BKV causes gradual impairment of renal functions and the sample did not include patients frequently observed to have BKVN in the native kidney.

Özet

AMAÇ: BK virüs nefropatisi (BKVN) çoğunluğu böbrek nakli olgularında tanımlansa da, öz böbreklerde de giderek artan oranda BKVN olguları tanımlanmaktadır. Çalışmada, akut böbrek yetmezliği nedeniyle böbrek biyopsisi yapılan organ nakli dışında bir nedene bağlı immünsüpresif hastaların renal biyopsi örneklerinde BKVN sıklığını araştırmayı amaçladık.GereÇ ve YÖnteMler: Ocak 2001- Ocak 2013 tarihleri arasında çeşitli nedenlerle böbrek biyopsisi yapılmış 1223 hastadan akut böbrek hasarı nedeniyle biyopsi yapılmış ve biyopsi esnasında immünsüpresif olup çalışmaya uygun olan 52 hasta çalışmaya dahil edildi. Çalışmaya alınan hastaların böbrek biyopsileri tekrar değerlendirilerek ışık mikroskopisinde BKV'ye ait olabilecek değişiklikler arandıktan sonra tüm biyopsi materyallerine SV40 immünhistokimyasal antikor boyaması yapıldı.BulGulAr: Olguların tanısal dağılımı şu şekildeydi; 29 hasta primer glomerülonefrit (GN), 18 hasta sekonder GN ve 5 hasta malignite. Hastaların ikisi (ALL ve NHL olguları) hariç hepsi immünsüpresif tedavi nedeniyle immünsüpresiftiler. Böbrek biyopsilerinde yapılan immün histokimyasal boyamada 52 olgunun hiçbirinde BKVN'ye ait bulguya rastlanmadı ve tüm olgularda SV40 negatif saptandı.sOnuÇ: Sonuç olarak çalışmamızda, akut böbrek hasarı nedeniyle böbrek biyopsisi yapılmış olgularda BKVN'yi saptayamamış olmamız, BKVN'nin böbrek fonksiyonlarında yavaş seyirli bir bozulmaya sebep olmasından veya bu çalışmanın BKV'nin öz böbrek nefropatisinin daha çok izlendiği hastaları içermemesinden kaynaklanmış olabilir.
