Abstract

Objective: Haemorrhagic cystitis associated with BK virus (BKV) is a common and life-threatening complication in patients with haematopoietic stem cell transplantation (HSCT). In this study, we aimed to investigate the incidence of BKV infection in children with HSCT. Methods: A total of 21 patients aged 7 months to 16 years followed between July 2014 and July 2015 were included in the study. 19 of the patients received allogeneic HSCT and 2 received autologous HSCT. artus® BK Virus RG PCR Kit (Qiagen GmbH, Hilden, Germany) was used for detection of BKV DNA in urine and blood samples. Results: BKV infection was detected in 10 (47%) of 21 patients. Cystitis due to BKV developed in 4 (19%) of the patients. Haemorrhagic cystitis was observed to appear at a median of 23 days after HSCT. Urinary viral load was found to be >108 copies/µl within the previous week before the development of cystitis, and this finding has been accepted as a prognostic indicator. On the other hand, viral load in blood increased to >104 copies/ µl after 21-28 days from the onset of cystitis. All patients with cystitis were allogeneic HSCT recipients under myeloablative therapy (high-intensity regimen) for conditioning regimen. Conclusions: Screening of HSCT recipients for BKV infection, especially for viruria, is important for establishing the predictive diagnosis of patients at high risk for haemorrhagic cystitis and for better management of their treatment.

Özet

Amaç: Hematopoetik kök hücre transplantasyonu (HKHT) yapılanhastalarda, BK virusu (BKV)’yla ilişkili hemorajik sistit, yaygınve hayatı tehdit eden bir komplikasyondur. Bu çalışmada,HKHT yapılan çocuk hastalardaki BKV infeksiyonu insidansınınaraştırılması amaçlanmıştır.Yöntemler: Çalışmaya Temmuz 2014 ile Temmuz 2015 tarihleriarasında izlenen yaşları 7 ay ve 16 yaş arasında değişen toplam21 hasta dahil edilmiştir. Hastaların 19’una alojenik, 2’sine otologHKHT yapılmıştır. BKV DNA’sının idrar ve kan örneklerindetespiti için artus® BK Virus RG PCR Kit (Qiagen GmbH, Hilden,Almanya) kullanılmıştır.Bulgular: 21 hastanın 10 (%47)’unda BKV infeksiyonu tespitedildi. Hastaların 4 (%19)’ünde BKV’ye bağlı sistit gelişti. Hemorajiksistitin nakilden medyan 23 gün sonra ortaya çıktığıgözlendi. Hemorajik sistit gelişmeden önceki haftada idrardaviral yük >108 kopya/µl bulundu ve prognostik bir gösterge olarakkabul edildi. Buna karşılık kandaki viral yük değerleri sistitinbaşlangıcından 21-28 gün sonra >104 kopya/µl düzeyine yükseldi.Sistit gelişen vakaların tamamı alojenik HKHT yapılan vehazırlık rejiminde myeloablatif tedavi (yüksek yoğunluklu rejim)alan hastalardı.Sonuçlar: HKHT hastalarının BKV infeksiyonu, özellikle virüriyönünden izlenmesi, hemarojik sistit için yüksek risk altındakihastaların prediktif tanısının konulması ve tedavilerinin daha iyiyönetilebilmesi açısından önemlidir.
