BACKGROUND: Tubuloreticular inclusions (TRIs) are anastomosing networks of microtubules that are frequently found in autoimmune diseases and viral infections. In renal allografts, TRIs have been reported in glomerular endothelial cells in association with viral infections and donor specific antibodies (DSAs), but their presence in peritubular capillaries has not been explored. METHODS: We collected seven cases with TRIs out of 148 consecutive renal allograft biopsies taken from Dec...

Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive disorder that results in irreversible renal damage due to 2,8-dihydroxyadenine (DHA) nephropathy. A 28-year-old man underwent living-related kidney transplantation for chronic kidney disease of unknown etiology. Numerous spherical brownish crystals observed in his urinary sediment on postoperative day 3 and were observed within the tubular lumen of renal allograft biopsy specimens on postoperative day 7. After a genetic diagnosis, febuxostat treatment was started on postoperative day 7, with the dosage gradually increased to 80 mg/day until complete the disappearance of 2,8-DHA crystals...

Since the mid-1980s magnetic resonance imaging (MRI) has been investigated as a non- or minimally invasive tool to probe kidney allograft function. Despite this long-standing interest, MRI still plays a subordinate role in daily practice of transplantation nephrology. With the introduction of new functional MRI techniques, administration of exogenous gadolinium-based contrast agents has often become unnecessary and true non-invasive assessment of allograft function has become possible. This raises the question why application of MRI in the follow-up of kidney transplantation remains restricted, despite promising results...

Chronic allograft injury (CAI) remains one of the biggest challenges in transplantation as it directly affects the long-term allograft survival, an area in which the scientific and transplantation communities have struggled to improve outcomes. Therefore, understanding the mechanisms of CAI is paramount to implement preventive measures and novel therapeutic options. In this review, we will address the latest evidence on CAI, potential etiologies and risk factors including non-adherence, antibody-mediated rejection, recurrence of glomerular disease, BK nephropathy, and calcineurin nephrotoxicity...

Arterial hypertension (HT) plays an important role and is a major factor in the occurrence and progression of chronic graft nephropathy. We evaluated 24-hour blood pressure (BP) profile in kidney transplant patients to identify factors predictive of abnormal circadian BP profile. BP was measured over a period of 24 hours using a noninvasive automatic device (EC-3H / ABPM) in 40 renal transplant patients (mean age = 37.2±12.2 years, M = 30, mean serum creatinine = 2.0±1.4 mg/dl). They were under the triple immunosuppressive therapy (CsA / Ts + Aza / MMF + PDN)...

The introduction of calcineurin inhibitors (CNI) has greatly improved graft survival in the past three decades. However, long-term graft survival is still limited due to chronic allograft injury and side-effects of immunosuppressive medication. Areas covered: The present overview gives an update on pharmacotherapeutic strategies after kidney transplantation. The main focus is on CNI-sparing regimens using co-stimulatory blockade and on new substances on the horizone. Expert opinion: CNI sparing regimens are well-established...

BACKGROUND: Polyomavirus nephropathy (BKVN) is an important cause of chronic allograft dysfunction (CAD). Recipient determinants (male sex, white race, and older age), deceased donation, high-dose immunosuppression, diabetes, delayed graft function (DGF), cytomegalovirus infection, and acute rejection (AR) are risk factors. Reducing immunosuppression is the best strategy in BKVN. The objective of our study was to evaluate CAD progression after therapeutic strategies in BKVN and risk factors for graft loss (GL)...

Reactivation of BK virus in renal allografts causes a destructive chronic infection. This single-center retrospective cohort study describes the evolution of BK virus allograft nephropathy (BKVAN) from 63 kidneys (from 61 patients) using sequential histopathology (454 biopsies, averaging 7.8 ± 2.6 per kidney) followed for 60.1 mo. Uninfected protocol biopsies formulated time-matched control Banff scores (n = 975). Interstitial inflammation occurred in 73% at diagnosis, correlating with viral histopathology (r = 0...

Being a member of the IL-17 family, comprising six structurally related ligands, IL-17A is a cytokine, produced by multiple cell types, such as CD4(+)αβ T cells, γδ T cells, natural killer cells, neutrophils, macrophages, dendritic cells, lymphoid tissue inducer cells, mast cells and plasma cells. IL-17A participates in tissue inflammation by inducing the expression of chemokines, proinflammatory cytokines and matrix metalloproteases. Besides its role in host defence against infectious diseases, IL-17A is involved in different autoimmune and inflammatory diseases...

Kidney transplant is the treatment of choice for end-stage chronic kidney disease. Kidneys generate 1,25-dihydroxyvitamin D (calcitriol) from 25-hydroxyvitamin D (calcidiol) for circulation in the blood to regulate calcium levels. Transplant patients with low calcidiol levels have an increased risk of metabolic and endocrine problems, cardiovascular disease, type 2 diabetes mellitus, poor graft survival, bone disorders, cancer, and mortality rate. The recommended calcidiol level after transplant is at least 30 ng/mL (75 nmol/L), which could require 1000-3000 IU/d vitamin D3 to achieve...

BK nephropathy (BKN) is a common cause of graft dysfunction following kidney transplantation. Minimization of immunosuppressive therapy remains the first line of therapy, but this may lead to rejection and graft loss. In some cases, despite lowering immunosuppression, BK infection can persist, leading to chronic damage and kidney failure. Currently, there is no specific anti-BK viral therapy. Recent in vitro experiments have demonstrated a reduction in BK viral replication when infected cells are treated with the combination of Leflunomide and Everolimus...

PURPOSE: Acute rejection of the kidney allograft remains the most important factor affecting the long-term graft outcome and is a major predictor of development of chronic damage and graft loss. Several studies have shown that early detection and treatment of subclinical rejection episodes may be beneficial for the graft outcome. The role of protocol (surveillance) biopsies and the value of donor specific antibodies (DSA) monitoring are still debatable. METHODS: This is a prospective observational study involving seventeen kidney recipients transplanted in north-eastern part of Poland who underwent "zero", 3-month and 12-month allograft biopsies as well as DSA assessment...
