Authors’ Contribution All authors recruited patients, collected data, reviewed and approved the paper, and gave approval for submission.
Hematological abnormalities, that is, anemia, leucopenia, and thrombocytopenia, are commonly observed in kidney-transplant patients [1, 2]. Apart from anemia caused by impaired kidney function, most cases of cytopenia are related to viral Inhibitors,Modulators,Libraries infections or to bone-marrow toxicity caused by drugs used at posttransplantation [1�C3].

In cases of cytopenia, viral infection is usually ruled out by searching for the viral genome in blood or in blood-marrow aspirates.

Parvovirus B19 infection is a classic cause of anemia [4], and cytomegalovirus (CMV) is well Inhibitors,Modulators,Libraries known to suppress bone-marrow function [5]. Patients who present with severe cytopenia, and in whom bacterial, viral, and fungal infections have been ruled out, should be assessed for possible toxic causes for these hematology abnormalities. Indeed, several drugs that are frequently Inhibitors,Modulators,Libraries used after transplantation can suppress bone-marrow activity; these include the mycophenolates, azathioprine, the mammalian target of rapamycin inhibitors, (val) ganciclovir, and cotrimoxazole [1�C3].

This toxicity can lead to immunosuppressants being discontinued and, thus, an increased risk of acute rejection [6], or the withdrawal of Inhibitors,Modulators,Libraries prophylactic drugs, which increases the risk of infections [3].

The human polyomavirus, BKV, is associated with severe complications, such Inhibitors,Modulators,Libraries as ureteric stenosis and Inhibitors,Modulators,Libraries polyomavirus-associated nephropathy (PVAN), which often occurs in kidney-transplant Brefeldin_A patients, and polyomavirus-associated Inhibitors,Modulators,Libraries hemorrhagic cystitis, which preferentially affects patients who have received an allogeneic hematopoietic stem-cell transplant [7]. BKV replicates in many cell types, particularly in peripheral blood mononuclear cells and in epithelial urinary cells [7, 8]. AV-951 It has been also demonstrated that BKV has a tropism to vascular endothelial cells [9]. A case of BKV-related hemophagocytic syndrome has been observed in a kidney-transplant patient [10]. Finally, BKV replication has been observed in the bone marrow and in the blood in a kidney-transplant patient [11]. The aim of our study was to search for BKV replication within the bone marrow of kidney-transplant patients presenting with a hematological disorder. 2.
