Abstract
Adenovirus nephritis (ADVN) is a rare and understudied complication of kidney transplantation. Unlike BK virus nephropathy (BKVN), our knowledge of clinicopathologic manifestations of ADVN remains rudimentary and essentially limited to case reports. To expand on this, we retrospectively studied 11 kidney transplant recipients with ADVN and compared their allograft biopsies to 33 kidney transplant recipients with BKVN using conventional microscopy and the 770 gene Nanostring Banff Human Organ Transplant Profiling Panel. Patients with ADVN had a median age of 44 years, were predominantly male, and developed ADVN at a median of 31 months post-transplantation. Eight patients presented with fever and ten had hematuria. The most common histologic manifestations included granulomas (82%), tubulocentric inflammation (73%), and tubular degenerative changes consistent with acute tubular necrosis (73%). During a median follow-up of 55 months after biopsy, three patients developed allograft failure from subsequent acute rejection. All seven patients with available follow-up PCR showed resolution of viremia at a median of 30 days after diagnosis. Compared to BKVN, ADVN demonstrated more granulomas and less tubulointerstitial scarring. On follow-up, patients with ADVN had more rapid clearance of viral DNA from plasma. Transcriptomic analyses showed that ADVN had increased expression of several pro-inflammatory transcriptomes, mainly related to innate immunity, was associated with increased expression of transcripts with inhibitory effects on inflammatory response and showed higher enrichment with neutrophils, which can cause aggressive but short-lasting damage. Thus, we demonstrate that, despite its association with aggressive neutrophil-rich inflammation, ADVN does not often lead to allograft failure. Hence, preventing subsequent acute rejection following resolution of ADVN may improve allograft survival.

Abstract
Modern immunosuppressive therapy has dramatically reduced the incidence of acute rejection and improved graft survival in kidney transplant patients. However, infectious complications remain an important issue. Amongst the various pathogens, viruses such as adenovirus and polyomavirus BK can directly cause acute or chronic graft dysfunction. Adenovirus mainly causes haemorrhagic cystitis and tubulointerstitial nephritis in kidney transplant patients. While patients show apparent clinical symptoms such as fever, dysuria, gross haematuria, frequency and urgency of urination, and most patients show acute graft dysfunction, these symptoms and graft dysfunction are reversible. Polyomavirus BK infection, however, is asymptomatic but graft outcome is poor if the patient develops tissue-invasive nephropathy confirmed by graft biopsy. Recently, an attempt to create a pathological classification for predicting the clinical course has been made by the Banff Working Group on Polyomavirus Nephropathy. With regards to treatment, the basic strategy is a reduction of calcineurin inhibitor and/or antimetabolites, and the effectiveness of several adjunct treatments has been investigated in several clinical trials. There are other unresolved issues, such as the diagnosis of subsequent acute rejection, the definition of remission, methods of resuming immunosuppression and long-term follow-up. Most of all, development of effective vaccines and novel drug discovery are necessary to prevent the development and progression of BKV-associated nephropathy.

Abstract
Due to the development of organ transplantation and its accompanying immunosuppression, recent years have been marked by the higher incidence of opportunistic viral infections that are of considerable importance among posttransplantation complications. A variety of viral infections, the possibility of their concomitant or subtle course, and the ability to cause life-threatening complications in recipients make relevant the description of existing diagnostic methods. The article summarizes the data available in the literature on the etiology, clinical symptoms, and morphological manifestations of viral infections, such as polyomaviruses, adenoviruses, herpesviruses, including HSV-1, HSV-2, cytomegalovirus (CMV), and Epstein-Barr virus. It describes the principles of differential diagnosis of kidney transplant damage caused by these viruses and that with acute cellular and humoral rejection, which plays an important role due to opposite approaches to treating these diseases.
