Data related to graft outcomes following posttransplant lymphoproliferative disease (PTLD) in pediatric kidney transplantation are scarce. Data were analyzed retrospectively from 12 children (8 boys) for three years after diagnosis of PTLD, with a loss of follow-up after 2 years in 2/12. In all cases, intensity of immunosuppressive therapy was reduced, with switch from calcineurin inhibitor to a mammalian target of rapamcyin (mTOR) inhibitor in 6 cases. Nine children were treated with 6 doses of rituximab according to the PED-PTLD-2005 protocol, with additional treatment in one child as per protocol...

BACKGROUND: Treatment for hyperphosphatemia in chronic kidney disease (CKD) involves dietary control of phosphorus intake, dialysis, and treatment with oral phosphate binders, none of which were approved by the Federal Food and Drug Administration in pediatric patients at the time of this study. METHODS: This was a phase 2, multicenter study (NCT01574326) with a 2-week, randomized, placebo-controlled, fixed-dose period (FDP) followed by a 6-month, single-arm, open-label, dose-titration period (DTP), with the aim to evaluate the safety and efficacy of sevelamer carbonate (SC) in hyperphosphatemic pediatric patients with CKD...

BACKGROUND: Tubulointerstitial nephritis (TIN) is an inflammatory disease of unknown pathogenesis. To evaluate a possible role of regulatory T cells (Tregs) in the pathophysiology of TIN with (TINU) and without uveitis, we investigated the presence and quantity of FOXP3(+) T regulatory lymphocytes in diagnostic kidney biopsies from pediatric patients. METHODS: A total of 33 patients (14 TIN and 19 TINU) were enrolled. The quantity of CD4(+), FOXP3(+) and double-positive T cells in formalin-fixed kidney biopsies was determined using double label immunohistochemistry with anti-human CD4 and FOXP3 antibodies...

There is increasing interest in telemedicine among physicians and patients; however, the evidence regarding the quality of care delivered by telemedicine, and telenephrology in particular, compared with in-person care is limited. In this review, different electronic modalities used to deliver nephrology care are reviewed and critiqued, with a focused analysis from the Australian and United States perspectives. Both countries are geographically expansive with significant rural populations where access to nephrology care is limited...

Importance: Conventional methods to diagnose and monitor chronic kidney disease (CKD) in children, such as creatinine level and cystatin C-derived estimated glomerular filtration rate (eGFR) and assessment of proteinuria in spot or timed urine samples, are of limited value in identifying patients at risk of progressive kidney function loss. Serum soluble urokinase receptor (suPAR) levels strongly predict incident CKD stage 3 in adults. Objective: To determine whether elevated suPAR levels are associated with renal disease progression in children with CKD...

Tubuloreticular inclusions (TRIs) are subcellular structures located within the cisternae of endoplasmic reticulum. Formation of TRIs has been linked to the exposure of excess interferon (IFN), either from endogenous or exogenous sources. In renal disease, TRIs have been most commonly associated with systemic lupus erythematosus (SLE), and human immunodeficiency virus-associated nephropathy (HIVAN). Case reports of patients with renal biopsies showing TRIs without underlying SLE or HIV are infrequent in adults, and to our knowledge none have been reported in children...

INTRODUCTION: The most common hereditary kidney condition is autosomal dominant polycystic kidney disease. It is the cause of 5-10% of end-stage renal disease. Its symptoms are generally late-onset, typically leading to development of hypertension and chronic kidney disease. Ultrasonography is the imaging modality of choice in its diagnosis and management. The aim of this study is to determine the diagnostic value of grayscale ultrasound imaging in evaluating disease severity. MATERIALS AND METHODS: The study group consisted of 81 patients diagnosed with autosomal dominant polycystic kidney disease, 35 adults and 46 children...

Chronic kidney disease (CKD) has become a major public health problem in Brazil and worldwide. There are many causes of CKD, being the congenital anomalies of the kidney and urinary tract and the glomerular diseases very common in pediatric patients, while diabetic nephropathy, CKD due to chronic arterial hypertension and glomerular diseases are predominant in adult patients. Many endogenous mediators have been related to the pathophysiology of CKD, being relevant the effects of the renin-angiotensin system (RAS) and the immune-inflammatory mediators including cytokines...

BACKGROUND: Darbepoetin alfa is a commonly prescribed erythropoiesis-stimulating agent (ESA) for correcting anemia in pediatric chronic kidney disease (CKD) patients. However, little information exists on its use in ESA-naïve patients. This study evaluated the efficacy and safety of darbepoetin alfa in pediatric patients initiating ESA therapy. METHODS: One-hundred sixteen pediatric ESA-naïve subjects (aged 1-18 years) with CKD stages 3-5D and hemoglobin (Hb) <10 g/dl from 43 centers in the US, Europe, and Mexico were randomized by age (three groups) and dialysis status (yes vs...

BACKGROUND: The search for risk factors for chronic kidney disease in children with focal segmental glomerulosclerosis (FSGS) is important in defining prognosis and individualized treatment. This study preliminarily investigated whether CD44 immunostaining in glomerular parietal epithelial cells (PECs) is a prognostic marker in pediatric FSGS. METHODS: In this retrospective study, 26 patients with FSGS, biopsied from 1985 to 2010, were evaluated. Immunohistochemistry for CD44 was performed in all cases...

BACKGROUND: Chronic kidney disease-associated mineral bone disorder (CKD-MBD) is common in pediatric kidney disease patients and a risk factor for future cardiovascular disease (CVD). Fibroblast growth factor-23 (FGF23) and Klotho are novel key players in CKD-MBD, and has been suggested to be involved in the development of CVD. METHODS: This prospective cohort study included 74 pediatric patients; 31 with CKD (age range 0.8-18.8 years, glomerular filtration rate (GFR) range 9-68 mL/min/1...

In contrast to adults where hypertension is a leading cause of chronic kidney disease, in pediatrics, hypertension is predominantly a sequela, however, an important one that, like in adults, is likely associated with a more rapid decline in kidney function or progression of chronic kidney disease to end stage. There is a significant issue with unrecognized, or masked, hypertension in childhood chronic kidney disease. Recent evidence and, therefore, guidelines now suggest targeting a blood pressure of <50th percentile for age, sex, and height in children with proteinuria and chronic kidney disease...

Pediatric acute kidney injury is a condition that is underdiagnosed among children seen in the emergency department, and it has been associated with significant morbidity and mortality, including increased risk for chronic kidney disease. The most common etiologies in pediatric patients are now known to be due to hypovolemia, sepsis, shock, and cardiac dysfunction. This issue compares 3 classification systems for the diagnosis and staging of acute kidney injury and reviews the etiologies that lead to kidney injury in children...

Prevalence, clinicopathological features, and outcome of childhood idiopathic steroid-resistant nephrotic syndrome (ISRNS) vary in different countries. We report on these parameters in a single center in Khartoum. We retrospectively reviewed all the records of children with idiopathic nephrotic syndrome (INS) followed up in the pediatric renal unit, Soba Hospital, Khartoum between 2001 and 2012. ISRNS was defined as no remission within four weeks of daily prednisolone at a dose of 60 mg/m2. In 430 children with INS 130 (28%) had SRNS with a mean age of 7...

Multiple groups of patients have been recognized for having high rates of non-responders to the Hepatitis B vaccine including those with HIV, inflammatory bowel disease, and chronic kidney disease. These patients are at increased risk for infection due to both the nature of their underlying diseases and the immunosuppressive drugs they are commonly prescribed. Identification of groups with high non-response rates is essential in order to establish vaccination guidelines and prevent serious infections in already susceptible patients...

Recent studies in adult chronic kidney disease (CKD) suggest that metabolic acidosis is associated with faster decline in estimated glomerular filtration rate (eGFR). Alkali therapies improve the course of kidney disease. Here we investigated the prevalence and determinants of abnormal serum bicarbonate values and whether metabolic acidosis may be deleterious to children with CKD. Associations between follow-up serum bicarbonate levels categorized as under 18, 18 to under 22, and 22 or more mmol/l and CKD outcomes in 704 children in the Cardiovascular Comorbidity in Children with CKD Study, a prospective cohort of pediatric patients with CKD stages 3-5, were studied...

BACKGROUND: Pediatric chronic kidney disease is psychologically, financially, and physically demanding on parents providing care. Parents often feel isolated because of the rarity of the condition, and geographic isolation often compounds this perception in Canada. Many parents seek assistance online for both information and social support. OBJECTIVE: This study examines an online portal, titled "Ability Online," which was designed to provide support and information to a diverse group of parents using chat facilities, bulletin boards, and e-mail...
