    The increasing rates of acute interstitial nephritis in Australia: a single centre case series.
    BMC Nephrol 2017 Oct 31;18(1):329. Epub 2017 Oct 31.
    Department of Renal Medicine, Royal Brisbane and Women's Hospital, Herston, QLD, 4029, Australia.
    Background: The Australian Institute of Health and Welfare's first report into acute kidney injury demonstrated a significant increase in the incidence of acute-tubulo interstitial nephritis, the ICD-10 code representing both acute interstitial nephritis and pyelonephritis, in women aged less than 55 years. In contrast, recent case series have reported rising rates of drug induced acute interstitial nephritis predominantly among elderly patients. Due to several limitations with the Australian Institute of Health and Welfare report, this new trend requires further investigation to determine if rates of acute interstitial nephritis are truly increasing among younger Australian women.

    Background: To assess whether serum osteoprotegerin (OPG) and/or fetuin-A predict mortality and cardiovascular (CV) morbidity and mortality in hemodialysis patients.

    Methods: Multicenter, observational, prospective study that included 220 hemodialysis patients followed up for up to 6 years. Serum OPG and fetuin-A levels were measured at baseline and their possible association with clinical characteristics, CV risk biomarkers, carotid ultrasonographic findings, as well as their association with overall and CV mortality and CV events were assessed.

    Fibronectin glomerulopathy complicated with persistent cloaca and congenital esophageal atresia: a case report and literature review.
    BMC Nephrol 2017 Sep 6;18(1):288. Epub 2017 Sep 6.
    Kidney Unit, National Fukuoka-Higashi Medical Center, Fukuoka, Japan.
    Background: Fibronectin glomerulopathy is a rare, inherited, autosomal dominant, glomerular disease characterized by proteinuria, microscopic hematuria, hypertension, massive glomerular deposits of fibronectin, and slow progression to end-stage renal failure. Because the incident of fibronectin glomerulopathy is extremely low, the pathophysiology, genetic abnormalities, epidemiology, and mechanisms remain to be elucidated.

    Case Presentation: We report a 21-year-old woman with fibronectin glomerulopathy, who had been diagnosed with persistent cloaca and congenital esophageal atresia at birth. Read More

    Indoleamine 2, 3-dioxygenase (IDO) increases during renal fibrogenesis and its inhibition potentiates TGF-β 1-induced epithelial to mesenchymal transition.
    BMC Nephrol 2017 Sep 6;18(1):287. Epub 2017 Sep 6.
    Postgraduate Program in Medicine, Universidade Nove de Julho (UNINOVE), Rua Vergueiro, 235, 2º subsolo, São Paulo, 01504-001, São Paulo, Brazil.
    Background: Indoleamine 2, 3-dioxygenase (IDO) is an immunomodulatory molecule that has been implicated in several biological processes. Although IDO has been linked with some renal diseases, its role in renal fibrosis is still unclear. Because IDO may be modulated by TGF-β1, a potent fibrogenic molecule, we hypothesized that IDO could be involved in renal fibrosis, especially acting in the TGF-β1-induced tubular epithelial-mesenchymal transition (EMT).

    Bone turnover markers are associated with bone density, but not with fracture in end stage kidney disease: a cross-sectional study.
    BMC Nephrol 2017 Sep 6;18(1):284. Epub 2017 Sep 6.
    Department of Renal Medicine, Aarhus University Hospital, Palle Juul-Jensens Boulevard 99, 8200, Aarhus N, Denmark.
    Background: Fracture risk is increased in chronic kidney disease (CKD), but assessment of bone fragility remains controversial in these patients. This study investigated the associations between bone turnover markers, bone mineral density (BMD), and prevalent fragility fracture in a cohort of kidney transplantation candidates.

    Methods: Volumetric BMD of spine and hip was measured by quantitative computed tomography. Read More

    A chronic hemodialysis patient with isolated pulmonary valve infective endocarditis caused by non-albicans Candida: a rare case and literature review.
    BMC Nephrol 2017 Sep 6;18(1):286. Epub 2017 Sep 6.
    Department of Internal Medicine, Cardinal Tien Hospital An-Kang branch, School of Medicine, Fu-Jen Catholic University, No. 15, Chezi Road., Hsin-Tien District, New Taipei City, 23155, Taiwan, Republic of China.
    Background: Isolated pulmonary valve infective endocarditis caused by Candida is rare in chronic hemodialysis patients. The 2009 Infectious Diseases Society of America guidelines suggest the combined use of surgery and antibiotics to treat candidiasis; however, successful nonsurgical treatment of Candida endocarditis has been reported.

    Case Presentation: A 63-year-old woman with end-stage kidney disease was admitted to our hospital after experiencing disorientation for 5 days. Read More

    Doxycycline treatment in dialysis related amyloidosis: discrepancy between antalgic effect and inflammation, studied with FDG-positron emission tomography: a case report.
    BMC Nephrol 2017 Sep 6;18(1):285. Epub 2017 Sep 6.
    Nuclear Medicine Centre Hospitalier Le Mans, 72000, Le Mans, France.
    Background: No effective treatment is currently available and dialysis related amyloidosis continues to be invalidating in long-term dialysis patients. A recent case series reported reduction of osteoarticular pain on doxycycline treatment, extending the indications of this drug, used in other uncommon forms of amyloidosis, to dialysis patients. Explanations of the antalgic effect were the anti-inflammatory properties and anti-coiling effects of tetracycline. Read More
