Medullary sponge kidney (MSK) is a cause of nephrocalcinosis, associated with hematuria, renal colic, pyelonephritis. There are rare and atypical MSK cases characterized by chronic severe pain (CP), whose features are unknown, in particular the relationship with the stone disease activity. This study analyzes a cohort of MSK-CP patients belonging to three North-America self-support Facebook groups. Patients had to self-administer an on-line questionnaire (on intensity, progression and MSK-associated conditions, stone-related disease, pain features, drug use), the Brief Pain Inventory, the Fatigue Severity Score, and Wisconsin Quality of Life (WQL) in stone formers questionnaires...

Chronic Kidney Disease affects approximately 10% of the world's adult population: it is within the top 20 causes of death worldwide, and its impact on patients and their families can be devastating. World Kidney Day and International Women's Day in 2018 coincide, thus offering an opportunity to reflect on the importance of women's health and specifically their kidney health, on the community, and the next generations, as well as to strive to be more curious about the unique aspects of kidney disease in women so that we may apply those learnings more broadly...

AIM: To describe the pathological characteristics of the peritumoral non-neoplastic renal parenchyma (NNRP) and to investigate their impact on long-term renal function after partial nephrectomy. MATERIALS AND METHODS: In our institutional robotic partial nephrectomy database, we identified 394 cases with pathological assessment of the NNRP and long-term postoperative renal functional follow-up. The NNRP was classified as normal (healthy renal parenchyma) or abnormal, based on the presence of arteriosclerosis, glomerulosclerosis, interstitial fibrosis, interstitial inflammation, and/or tubulopapillary hyperplasia...

Colchicine is the first-line treatment for familial Mediterranean fever (FMF), preventing both inflammatory attacks as well as the development of amyloidosis in the majority of the patients. However approximately 5-10% of patients are colchicine resistant/intolerant. Side effects of colchicine are more prominent in renal transplant recipients due to interaction with immunosuppressive drugs. Anti-interleukin (IL)-1 drugs (anakinra, canakinumab and rilonacept) have emerged as the most promising drugs in the treatment of colchicine-resistant and/or intolerant FMF...

It is widely thought that patients with end-stage renal disease who remain vocationally active and/or commercially insured following dialysis initiation have better clinical outcomes and higher quality of life than those who do not. However, scientifically robust data are lacking. Here, we examined whether vocational status (active, N = 1848; inactive, N = 10,001) and, separately, insurance status (commercial, N = 4858; Medicare/self-pay, N = 13,329; Medicaid, N = 3528) were associated with clinical outcomes and Kidney Disease Quality of Life (KDQOL) scores among a cohort of patients who initiated dialysis at a large US dialysis organization during 2015-2016...

REVIEW
Orson W Moe, Li Hao Richie Xu
Hyperuricosuric calcium urolithiasis is a condition of mixed calcium oxalate stones characterized by hyperuricosuria either in isolation or in conjunction with other risk factors for calcium oxalate stones such as hypercalciuria, hyperoxaluria, and hypocitraturia. There are three proposed physicochemical models of pathogenesis where urate in its crystalline phase via heterogeneous nucleation, in its colloidal phase via removal of crystallization inhibitors, and in solution via precipitation crystallization, can all increase propensity to calcium oxalate precipitation...

BACKGROUND: Although only high-flow arteriovenous fistulas (AVFs) are postulated to cause high-output cardiac failure (HOCF), there are currently no universally accepted criteria defining a high-flow fistula. METHODS: To verify if vascular access blood flow (Qa) ≥ 2000 ml/min provides an accurate definition of high-flow fistula, we selected 29 consecutive patients with Qa ≥ 2000 ml/min at color-duplex ultrasound examination and assessed them for the presence of cardiac failure symptoms; transthoracic echocardiography was also performed...

Aim of the study was the definition of a predictive model for the initial diagnosis of thrombotic microangiopathies (TMA). We retrospectively collected data on all adult patients admitted to the Gemelli Hospital from 2010 to 2014. ICD-9 codes from primary diagnoses were used for TMA diagnosis. Demographic and laboratory characteristics on admission of patients with TMA were then compared with a random sample of 500 patients with other diagnoses. The prediction model was externally validated in a cohort from another hospital...

BACKGROUND: Cardiovascular calcification (CVC) is a major concern in hemodialysis (HD) and the loss of endogenous modulators of calcification seems involved in the process. Phytate is an endogenous crystallization inhibitor and its low molecular mass and high water solubility make it potentially dialyzable. SNF472 (the hexasodium salt of phytate) is being developed for the treatment of calciphylaxis and CVC in HD patients. We aimed to verify if phytate is lost during dialysis, and evaluate SNF472's behaviour during dialysis...

BACKGROUND: Low birth weight (LBW) is associated with reduced nephron endowment. Clinical-pathologic features of post adaptive focal segmental glomerulosclerosis (FSGS) have been observed in subjects with prematurity and very LBW. METHODS: We aimed to investigate the correlation between LBW and outcome in a cohort of 89 children with idiopathic nephrotic syndrome (NS) (2-12 years-old at onset, followed for > 3 years), of whom 21 with LBW (birth weight < 10th percentile for gestational age, gender, ethnicity, and maternal parity or birth weight < 2500 g)...

CKD-related nutritional therapy (NT) is a crucial cornerstone of CKD patients' treatment, but the role of NT has not been clearly investigated in autosomal dominant polycystic kidney disease (ADPKD). Several clinical studies have focused on new pharmacological approaches to delay cystic disease progression, but there are no data on dietary interventions in ADPKD patients. The aim of this paper is to analyze the evidence from the literature on the impact of five nutritional aspects (water, sodium, phosphorus, protein intake, and net acid load) in CKD-related ADPKD extrapolating-where information is unavailable-from what occurs in CKD non-ADPKD patients Sodium intake restriction could be useful in decreasing the growth rate of cysts...

BACKGROUND: Patients undergoing abdominal aortic aneurysm (AAA) surgery with suprarenal clamping are at high risk for acute kidney injury (AKI) and major cardiac and cerebrovascular events (MACCE). We aimed to assess whether the stroke volume variation (SVV), a measure of hemodynamic instability, is associated with AKI in hypertensive patients undergoing elective AAA surgery with suprarenal clamping. METHODS: In a cohort of 51 hypertensive patients, we performed serial measurements of SVV (n = 459) and serum creatinine (sCr) (n = 255)...

INTRODUCTION: There are numerous reports in the literature describing acute kidney injury in pregnancy (P-AKI) due to various obstetric complications. However, there is a dearth of studies on AKI related to pregnancy-specific disorders from India. We aimed to analyze clinical features and outcome of P-AKI related to pregnancy-specific disorders compared to total pregnancy, in India. METHOD: All pregnant women attending the department of Obstetrics and Gynecology from November 2014 to July 2016 were screened for AKI based on: (1) sudden elevation of serum creatinine ≥ 1 mg/dl; (2) oligoanuria for > 12 h; and (3) need for dialysis...

Sepsis is a serious medical condition that can lead to multi-organ failure and shock, and it is associated with increased mortality. Acute kidney injury (AKI) is a frequent complication of sepsis in critically ill patients, and often requires renal replacement therapy. The pathophysiology of AKI in sepsis has not yet been fully defined. In the past, classic theories were mainly focused on systemic hemodynamic derangements, underscoring the key role of whole kidney hypoperfusion due to reduced renal blood flow...

Systemic lupus erythematosus (SLE) patients clinically presenting with nephrotic syndrome demonstrating minimal change disease (MCD), mesangial proliferation (MsP) or focal segmental glomerulosclerosis (FSGS), while on electronic microscopy, diffuse podocyte foot process effacement in absence of sub-epithelial or sub-endothelial deposition is the only morphological feature and now diagnosed as lupus podocytopathy. Lupus podocytopathy with glomerular morphology of MCD or MsP usually presents with typical nephrotic syndrome and sensitive to glucocorticoid treatment, but the relapse rate could reach up to 90% on maintenance treatment with glucocorticoid alone...

BACKGROUND: Internal jugular vein cannulation has become increasingly widespread. Compared to the left internal jugular vein (LIJV), the right internal jugular vein (RIJV) is the preferred choice for the placement of central venous catheter (CVC) for hemodialysis, mostly due to the major technical difficulties and higher rate of complications of the LIJV approach. We aimed to investigate whether variability in the direction of the LIJV/brachiocephalic vein (BV) axis on the frontal plane could be a decisive factor in determining CVC dysfunctions...

Chronic lymphocytic leukemia (CLL) may induce renal complications, which are becoming increasingly common, but in this context the occurrence of minimal change disease (MCD) remains rare. Monoclonal B lymphocytosis (MBL) is a precursor state of CLL and is currently under recognized. Since MBL is seen as a benign disorder that rarely evolves into CLL, screening for MBL is not standardized and does not require any treatment. When reviewing renal disease associated with MBL, there is very scant data in the literature and to date there is no case describing the association between MBL and MCD...

Acute kidney injury (AKI) is independently associated with significant morbidity and mortality, and is thus an important challenge facing physicians in modern healthcare. This narrative review assesses the impact of strategies employed to tackle AKI following the 2009 NCEPOD report on acute kidney injury (Sterwart et al. Acute kidney injury: adding insult to injury, pp 1-22, 2009). There is scarce and heterogeneous research into hard end points such as mortality and AKI progression for AKI interventions. This review found that e-alerts have varying effects on mortality and AKI progression, but decrease the incidence of contrast-induced AKI...

BACKGROUND: Epstein-Barr virus (EBV) was the first human virus identified to express microRNA (miRNA). To date, 44 mature miRNAs are encoded for within the EBV genome. EBV miRNAs have not been profiled in paediatric renal transplant recipients. In this study, we investigated circulating EBV miRNA profiles as novel biomarkers in paediatric renal transplant patients. METHODS: Forty-two microRNAs encoded within 2 EBV open reading frames (BART and BHRF) were examined in renal transplant recipients who resolved EBV infection (REI) or maintained chronic high viral loads (CHL), and in non-transplant patients with acute infectious mononucleosis (IM)...
