The experience using anidulafungin for the treatment of invasive fungal infections in pediatrics is limited. In this article, we describe our experience in 55 children. Anidulafungin was administered intravenously at a loading dose of 3 mg/kg once daily, followed by 1.5 mg/kg every 24 hours over a mean period of 14 days (range: 7-22 days). Patients' median age was 114 months old (interquartile range: 32-168 months old). All patients had underlying diseases. Among patients with bone marrow transplant, the difference in white blood cell count, transaminase levels, and renal function at baseline and at the end of anidulafungin administration was not significant...

Extracellular vesicles, such as exosomes and microvesicles, are host cell-derived packages of information that allow cell-cell communication and enable cells to rid themselves of unwanted substances. The release and uptake of extracellular vesicles has important physiological functions and may also contribute to the development and propagation of inflammatory, vascular, malignant, infectious and neurodegenerative diseases. This Review describes the different types of extracellular vesicles, how they are detected and the mechanisms by which they communicate with cells and transfer information...

Urinary tract infections are a major cause of morbidity and hospitalization after renal transplantation. Patients treated with immunosuppressive drugs suffer not only from common uropathogens but also from opportunistic infections caused by unusual uropathogens. Sterile pyuria is associated with numerous infectious agents including viruses, fungi, and atypical or fastidious organisms. The objective of this study was to investigate the pathogens using real-time multiplex polymerase chain reaction (rtMPCR) assay in sterile pyuria of renal transplant recipients...

BACKGROUND: BK virus (BKV)-associated nephropathy (BKVAN) is often associated with renal graft dysfunction. When renal transplant recipients present with high clinical suspicion for BKVAN (high serum and urine BKV titer with graft dysfunction) but their graft biopsies stain negatively for BKV, non-correlated situations between the two tests often lead to a dilemma about how to treat them. METHODS: This retrospective investigation was conducted to determine how real-time quantitative PCR (qPCR) for BKV, routinely applied to serum and urine, could be helpful in identifying the existing BKV in biopsy tissue stained negatively for BKV...

BACKGROUND: Kidney transplantation is the treatment of choice for patients with end-stage renal disease. The standard surgery uses the recipient's iliac vessels for vascular anastomosis. Thrombosis and/or stenosis of the iliac vein, which are possible complications of multiple vascular access points for dialysis, can be detected intraoperatively, constituting a surgical challenge. An infrequently reported option is the use of the gonadal vein. OBJECTIVES: This study aims to evaluate the outcomes of venous anastomosis in the gonadal vein in patients with iliac vein thrombosis and/or stenosis submitted to kidney transplantation...

BACKGROUND: Chronic refractory hypotension (IDH, intradialytic hypotension) is a rare but serious problem encountered in patients on hemodialysis. Patients with chronic hypotension are often disqualified by transplant teams from renal transplantation. This is due to the possibility of an enormous risk of ischemic complications. CASE PRESENTATION: We describe a 44-year old female patient with severe refractory hypotension (mean BP 60/30 mmHg, the lowest 48/28 mmHg), which appeared after bilateral laparoscopic nephrectomy of the infected kidneys...

Varicella Zoster Virus (VZV) is a well-known virus that belongs to the Herpesviridae family which induces a self-limited disease except in specific cases in particular among stem cell transplant patients. This virus is not known however to trigger atypical Hemolytic Uremic Syndrome (aHUS). Here we report the case of a six-year-old boy who was hospitalized with fever and abdominal pains associated to pruritic and vesicular rash, thrombocytopenia and acute renal failure. He was diagnosed with aHUS precipitated by varicella virus...

Neonates born to transplanted mothers are exposed to immunosuppressive drugs during gestation and have a higher risk of being born prematurely and small for gestational age than the general population. We have prospectively followed up 27 children born to renal transplanted mothers from a single center and 31 healthy children born at term with adequate weight for gestational age. Comparisons of weight and length measurements were made at birth, 1 month (±0.9), 3 months (±1.0), 6 months (±1.0), 9 months (±1...

OBJECTIVES: Valganciclovir 900 mg/day is approved for cytomegalovirus (CMV) prophylaxis, but 450 mg/day is seems also effective. We systematically reviewed the efficacy and safety of low-dose versus high-dose valganciclovir prophylaxis in renal transplantation recipients. METHODS: An electronic search was conducted up to November 29, 2016. The primary outcomes were incidences of CMV, CMV disease, mortality and opportunistic infection. The second outcomes were acute rejection, allograft loss, adverse drug reaction (ADR)...

BACKGROUND: Cytomegalovirus (CMV) establishes a lifelong infection that is efficiently controlled by the immune system; this infection can be reactivated in case of immunosuppression such as following solid organ transplantation. CMV viraemia has been associated with CMV disease, as well as increased mortality and allograft failure. Prophylactic antiviral medication is routinely given to renal transplant recipients, but reactivation during and following cessation of antiviral prophylaxis is known to occur...

In a 24-month, multicenter, single-arm, prospective study, 56 pediatric liver transplant patients with or without basiliximab induction were converted at 1-6 months post-transplant from standard calcineurin inhibitor (CN) therapy (± mycophenolic acid), to everolimus with reduced exposure to CNI (tacrolimus n=50, cyclosporine n=6). Steroid therapy was optional. Recruitment was stopped prematurely due to high rates of PTLD, treatment-related serious infections leading to hospitalization and premature study drug discontinuation...

There are only a few reports of successful use of mammalian target of rapamycin (mTORI) as primary immunosuppression in pediatric heart transplantation. Compared to calcineurin inhibitors, mTORI have less side effects, especially nephrotoxicity, infections and malignancies. A retrospective study was conducted at our institution of all 170 heart transplants from 1995-2015. Nineteen patients were switched from tacrolimus(n=15) or cyclosporin(n=4) to everolimus(n=4) or sirolimus(n=15) due to nephrotoxicity(n=5), malignancy(n=8), EBV viremia/reactive plasmacytic changes(n=5) and immune hemolytic anemia(n=1)...

Herein, we describe a case of early belatacept conversion in a human immunodeficiency virus (HIV)-positive kidney transplant recipient in an effort to improve suboptimal graft function and avoid drug interactions following anti-thymocyte globulin (ATG) administration. We observed improvement in renal function without HIV disease progression or opportunistic infections. Donor-specific antibodies appeared shortly after conversion but cleared without intervention. This case highlights belatacept as a means to improve renal function and avoid significant drug interactions even following ATG induction...

REVIEW
Laura E Baldassari, John W Rose
Daclizumab is a humanized monoclonal antibody directed towards CD25, the alpha subunit of the high-affinity interleukin (IL)-2 receptor. Daclizumab exerts its effects via multiple mechanisms, including reduction of IL-2-mediated lymphocyte activation and upregulation of CD56-bright natural killer cells. Intravenous daclizumab (Zenapax™) was initially approved for prevention of rejection in renal transplant. In subsequent early testing, followed by larger-scale phase II and phase III trials, both intravenous and subcutaneous daclizumab have demonstrated clinical efficacy in the treatment of multiple sclerosis...

Myelodysplasia includes a group of developmental anomalies resulting from defects that occur during neural tube closure. Urological morbidity in patients with myelodysplasia is significant and if not treated appropriately in a timely manner can potentially lead to progressive renal failure, requiring dialysis or transplantation. We report the case of a 13-year old girl with neurogenic bladder who presented chronic renal failure secondary to lipomyelomeningocele with retethering of cord. She was managed with urinary indwelling catheterization until optimization of renal function and then underwent detethering of cord with excision and repair of residual lipomeningomyelocele...

OBJECTIVES: The most common complications after renal transplant are urologic and are a cause of significant morbidity in a vulnerable population. We sought to characterize the timing and predictors of urologic complications after renal transplant using a statewide database. MATERIALS AND METHODS: We queried the New York Statewide Planning and Research Cooperative System database to identify patients who underwent renal transplant from 2005 to 2013. Postoperative complications included hydronephrosis, ureteral stricture, vesicoureteral reflux, nephrolithiasis, and urinary tract infections...
