PURPOSE OF REVIEW: Tissue hypoxia is present in kidneys from diabetic patients and constitutes a central pathway to diabetic kidney disease (DKD). This review summarizes regulation of hypoxia inducible factor (HIF) and interventions towards the same for treatment of DKD. RECENT FINDINGS: In the hypoxic diabetic kidney, HIF activity and the effects of HIF signaling seem to be cell-specific. In mesangial cells, elevated glucose levels induce HIF activity by a hypoxia-independent mechanism...

Coupled plasma filtration and adsorption (CPFA) is a detoxification system that combines a plasma adsorption circuit and a continuous renal replacement therapy circuit. Its main application is for sepsis and septic shock with or without acute renal failure. Several recent studies have suggested that CPFA can reduce the mortality when the volume of plasma absorbed on the styrenic resin is at least >0.18 L/kg/day. At present, new applications for CPFA are under investigation, also in patients without significant kidney failure...

Experimental or spontaneous genomic mutations of the renin-angiotensin system or its pharmacological inhibition in early life leads to renal abnormalities, including poorly developed renal medulla, papillary atrophy, hydronephrosis, inability to concentrate the urine, polyuria, polydipsia, renal failure, and anemia. At the core of such complex phenotype is the presence of unique vascular abnormalities: the renal arterioles do not branch or elongate properly and they have disorganized, concentric hypertrophy...

There have been few reports on pediatric transfusion-associated circulatory overload (TACO). A 5-year-old boy with neuroblastoma underwent resection of the residual tumor. Because anemia progressed at the end of the operation, transfusion of red cell component was initiated. Ten minutes later, he suddenly developed hypoxemia, tachypnea, and tachycardia. Although elevated blood pressure and bilateral infiltrative shadows on chest X-rays were not observed, TACO was diagnosed based on positive balance during operation and N-terminal pro-brain natriuretic peptide elevation...

BACKGROUND/AIMS: Bleeding is the most common complication after renal biopsy. Although numerous predictors of bleeding have been reported, it remains unclear whether arterial stiffness affects bleeding complications. METHOD: We performed an observational study of the renal biopsies performed in our division over an approximately 6-year period (May 2010 to May 2016). The clinical and laboratory factors were analyzed to reveal the risk factors associated with bleeding, with a focus on anemia (defined as a ≥10% decrease in hemoglobin [Hb] after biopsy)...

Anemia, which is highly prevalent in oncology patients, is one of the most established negative prognostic factors for several gynecologic malignancies. Multiple factors can cause or contribute to the development of anemia in patients with gynecologic cancers; these factors include blood loss (during surgery or directly from the tumor), renal impairment (caused by platinum-based chemotherapy), and marrow dysfunction (from metastases, chemotherapy, and/or radiation therapy). Several peri- and intra-operative strategies can be used to optimize patient management and minimize blood loss related to surgery...

The aim of the present review was to summarize and discuss previous findings concerning renal manifestations of primary mitochondrial disorders (MIDs). A literature review was performed using frequently used databases. The study identified that primary MIDs frequently present as mitochondrial multiorgan disorder syndrome (MIMODS) at onset or in the later course of the MID. Occasionally, the kidneys are affected in MIDs. Renal manifestations of MIDs include renal insufficiency, nephrolithiasis, nephrotic syndrome, renal cysts, renal tubular acidosis, Bartter-like syndrome, Fanconi syndrome, focal segmental glomerulosclerosis, tubulointerstitial nephritis, nephrocalcinosis, and benign or malign neoplasms...

Myeloma cast nephropathy is a major complication of multiple myeloma. Recent evidence has demonstrated that the earlier induction of bortezomib-based chemotherapy with plasma exchange (PE) provides better results for kidney function and patient survival. Due to its non-selectivity, PE with albumin replacement carries the risk of fibrinogen loss, leading to bleeding. We herein report a case of successful treatment of myeloma cast nephropathy using bortezomib-based chemotherapy and selective PE. A 61-year-old woman who had a 20-year history of type II diabetes mellitus was admitted to our hospital for the evaluation of hypercalcemia, severe kidney dysfunction, and anemia...

Acquired coagulation factor deficiency is a rare bleeding disorder caused by the inhibitors to coagulation factors. We report a case of an elderly hemodialysis patient who presented with the intermittent hematuria and anemia, associated with the prolonged activated partial thromboplastin time and prothrombin time. Laboratory examination revealed undetectable factor VIII activity, decreased factor V activity, and the presence of inhibitors to these coagulation factors. The patient was diagnosed to have inhibitors to coagulation factors VIII and V simultaneously...

Complement-mediated atypical hemolytic uremic syndrome (aHUS) is a rare disease associated with high mortality and morbidity. Renal biopsies often indicate thrombotic microangiopathy (TMA). The condition is caused by an excessive activation of the alternative pathway leading to depositions of membrane attack complexes (MAC) on host cells. It may depend on mutations in complement components and regulatory proteins, or the formation of complement-specific antibodies. Mainly, an environmental trigger (e.g. infection) is needed for the excessive response to develop...

Anemia can be related to decreased production or increased loss of erythrocytes, or both, leading to many underlying and often overlapping causes. A largely cereal-based diet with plenty of phytates, polyphenols, and other ligands that inhibit intestinal iron absorption predominated in preindustrial Europe and predominates in present-day developing countries alike. In both situations, we find poor hygienic conditions, which frequently lead to anemia of inflammation. The large number of possible causes and their interaction shows why it is so difficult to mitigate anemia prevalence...

Complement C1q is part of the C1 macromolecular complex that mediates the classical complement activation pathway: a major arm of innate immune defense. C1q is composed of A, B, and C chains that require post-translational prolyl 4-hydroxylation of their N-terminal collagen-like domain to enable the formation of the functional triple helical multimers. The prolyl 4-hydroxylase(s) that hydroxylate C1q have not previously been identified. Recognized prolyl 4-hydroxylases include collagen prolyl-4-hydroxylases (CP4H) and the more recently described prolyl hydroxylase domain (PHD) enzymes that act as oxygen sensors regulating hypoxia-inducible factor (HIF)...
