BACKGROUND: JC polyomavirus (JCPyV)-associated nephropathy (JCPyVAN) is a severe, but rare complication in adult renal transplant (RTx) recipients. Related data in pediatric patients are scarce. METHODS: Based on the CERTAIN Registry, we therefore performed a multi-center, retrospective study on the JCPyV antibody status, prevalence of JCPyV replication, and its associated disease in 139 pediatric RTx recipients (mean age, 8.5 ± 5.3 years). JCPyV DNA in plasma and/or urine was measured by quantitative PCR at a median time of 3...

Iron deficiency and iron deficiency anemia are highly prevalent among women throughout their lives. Some females are particularly vulnerable to iron deficiency/iron deficiency anemia, including those with heavy menstrual bleeding (HMB) and pregnant/postpartum women. Despite the high prevalence of iron deficiency/iron deficiency anemia in women, the condition is still underdiagnosed and therefore undertreated, with serious clinical consequences. Areas covered: The following review examines the impact of iron deficiency and iron deficiency anemia on clinical outcomes and quality of life in women from adolescence to post-menopause, paying particular attention to guidelines and current recommendations for diagnostic tests and management...

Lithium-Sulfur (Li-S) batteries are mostly known for their high energy density and cost-effectiveness. However, their intrinsic problems hinder their implementation into the marketplace. The most pronounced problems are the parasitic reactions which occur between lithium polysulfides species and lithium metal anode, the volume expansion of sulfur (80%) at the end of discharge and the safety issues which are linked with the use of lithium metal. Herein this work, two approaches are applied to prevent these effects; one approach is the use of Li2 S as cathode material, instead of starting from sulfur powder, both to circumvent the volume expansion of sulfur taking place during discharge and to enable lithium-free anodes cell assembling (i...

Brain and leptomeningeal metastasis (LMM) of non-small cell lung cancer is still associated with poor prognosis. Moreover, the current diagnostic standard for LMM often yields false negative results and the scientific progress in this field is still unsatisfying. We present a case of a 71-year old patient with an isolated LMM. While standard diagnostics could only diagnose a cancer of unknown primary, the use of [68 Ga]-Pentixafor-PET/CT (CXCR4-PET/CT, a radiotracer targeting CXCR4) and a liquid biopsy of the cerebrospinal fluid revealed the primary NSCLC...

BACKGROUND: Infants with a body weight of less than 10 kg are often not considered to be suitable candidates for renal transplantation (RTx). The objective of this study was to evaluate this arbitrary weight threshold for pediatric RTx. METHODS: We conducted a multicenter, retrospective, match-controlled cohort study on infants weighing less than 10 kg at time of engrafting (low-weight group [LWG], n = 38) compared to a matched control group (n = 76) with a body weight of 10-15 kg, using data from the first 2 years post-transplant derived from the CERTAIN Registry...

Turk J Pediatr 2017; 59: 6-12. Methotrexate (MTX) is the most commonly used disease modifying anti-rheumatic drug in juvenile idiopathic arthritis (JIA). We aimed to define predictor factors for response to MTX in Turkish children with oligo- and polyarticular JIA. We reviewed the medical files of 59 oligo- and 57 polyarticular JIA patients seen in the clinic between May 2008 and May 2013 and who received MTX for ≥6 months...

: Thromboembolic events in the pregnant and postpartum patient remain rare but potentially fatal complications. The aim of this section was to analyse the few prospective studies addressing the issue of thromboprophylaxis following a surgical procedure during and immediately after pregnancy, as well as national guidelines, and to propose European guidelines on this specific condition. Thromboprophylaxis is broadly recommended due to the combined risks of surgery and pregnancy or the postpartum period, regardless of the mode of delivery...

BACKGROUND: Because infections constitute a major cause of morbidity and mortality in paediatric renal allograft recipients, avoidance of preventable systemic infections by vaccination before transplantation is of utmost importance. However, data on the completeness of vaccinations and factors associated with incomplete vaccination coverage are scarce. METHODS: Within the framework of the Cooperative European Paediatric Renal Transplant Initiative (CERTAIN), we therefore performed a multi-centre, multi-national, retrospective study investigating the vaccination coverage before transplantation of 254 European children with end-stage renal disease (mean age 10...

Expression of the neonatal splice variant of the voltage-gated sodium channel α-subunit (VGSC) subtype Nav1.5 (nNav1.5), encoded by the gene SCN5A, was shown earlier to be upregulated in human breast cancer (BCa), both in vitro and in vivo. Channel activity promoted BCa invasion of Matrigel® in vitro and metastasis in vivo. Consequently, expression of nNav1.5 has been proposed as a functional biomarker of BCa cells with metastatic potential. Here, we have determined immunohistochemically both nNav1.5 and total VGSC (tVGSC) protein expression in a range of adult human tissues...

Iron deficiency, even in the absence of anemia, can be debilitating, and exacerbate any underlying chronic disease, leading to increased morbidity and mortality. Iron deficiency is frequently concomitant with chronic inflammatory disease; however, iron deficiency treatment is often overlooked, partially due to the heterogeneity among clinical practice guidelines. In the absence of consistent guidance across chronic heart failure, chronic kidney disease and inflammatory bowel disease, we provide practical recommendations for iron deficiency to treating physicians: definition, diagnosis, and disease-specific diagnostic algorithms...

Acyclovir is an antiviral agent widely used in herpetic infections in children. Although acyclovir is generally well tolerated, severe nephrotoxicity has been reported in some cases. In this report, we present a 16-year-old girl who developed acute renal failure due to acyclovir treatment and who needed repetitive hemodialysis. Renal biopsy was performed in order to confirm the diagnosis. A diagnosis of drug-related acute tubulointerstitial nephritis with focal tubular necrosis was made.

INTRODUCTION: Elevated hemoglobin A1c levels in patients with diabetes mellitus have been known as a risk factor for acute kidney injury after coronary artery bypass grafting. However, the relationship between hemoglobin A1c levels in non-diabetics and acute kidney injury is under debate. We aimed to investigate the association of preoperative hemoglobin A1c levels with acute kidney injury in non-diabetic patients undergoing isolated coronary artery bypass grafting. METHODS: 202 non-diabetic patients with normal renal function (serum creatinine <1...

Direct detection of F8 and F9 sequence variants in maternal plasma of hemophilia carriers has been demonstrated by microfluidics digital PCR. Noninvasive prenatal assessment of the most clinically relevant group of sequence variants among patients with hemophilia, namely, those involving int22h -related inversions disrupting the F8 gene, poses additional challenges because of its molecular complexity. We investigated the use of droplet digital PCR (ddPCR) and targeted massively parallel sequencing (MPS) for maternal plasma DNA analysis to noninvasively determine fetal mutational status in pregnancies at risk for hemophilia...

Excessive bleeding at surgery is a feared complication in patients with inherited platelet disorders. However, very few studies have evaluated the frequency of surgical bleeding in these hemorrhagic disorders. We performed a worldwide, multicentric, retrospective study to assess the bleeding complications of surgery, the preventive and therapeutic approaches adopted, and their efficacy in patients with inherited platelet disorders: the Surgery in Platelet disorders And Therapeutic Approach (SPATA) study. We rated the outcome of 829 surgical procedures carried out in 423 patients with well-defined forms of inherited platelet disorders: 238 inherited platelet function disorders and 185 inherited platelet number disorders...

Dyslipidemia contributes to cardiovascular morbidity and mortality in pediatric transplant recipients. Data on prevalence and risk factors in pediatric cohorts are, however, scarce. We therefore determined the prevalence of dyslipidemia in 386 pediatric renal transplant recipients enrolled in the CERTAIN registry. Data were obtained before and during the first year after RTx to analyze possible non-modifiable and modifiable risk factors. The prevalence of dyslipidemia was 95% before engraftment and 88% at 1 year post-transplant...
