Zur Untersuchung des Einflusses von tubularem HIF auf die renale EPO-Produktion generierte Navid Farsijani ein genetisches Mausmodell, in dem durch tubulare Vhl-Ablation, tubulare Epithelzellen HIF uberexprimieren. Die tubulare Vhl-Ablation fuhrte zu einer prompten Suppression der renalen EPO-Produktion. Anhand weitere konditioneller Mausmodelle zeigt der Autor, dass die Entwicklung der Anamie von HIF-abhangig ist, proximale Tubuluszellen fur die Regulation von EPO im Nephron verantwortlich sind und die tubulare Vhl-Ablation mit einer Reduktion der mitochondrialen Masse sowie einer Erhoehung des kortikalen Gewebssauerstoffpartialdruckes (PtO2) einhergeht. Dies spricht fur eine multi-zellulare Regulation der renalen EPO-Synthese, in der eine Homoeostase zwischen tubularen Epithelzellen und REPC fur eine adaquate EPO-Produktion der Niere notwendig ist. Zudem koennte der EPO-suppressive Effekt von tubularem HIF einen pathophysiologischen Faktor in der Entstehung von renalen Anamien darstellen.

Adenocarcinoma is the predominant malignancy found in the colon and rectum. Colorectal cancer is the third most common cancer diagnosed in the developed world with a high incidence of mortality and morbidity. The average five-year survival rate remains poor at 55%, although the development of new drugs has improved the survival rate of colorectal cancer patients. The prognosis of colorectal cancer remains poor in spite of the development of novel therapeutic strategies. Human colorectal cancer represents a heterogeneous group of diseases, and its molecular classification is increasingly important. Characterization of novel biomarker targets may lead to prolong the survival rate of colorectal cancer. Biomarkers may have a potential role in screening, diagnosis, prognosis and monitoring disease. Mutations in the KRAS gene in ~40% of tumors have been reported to be induced by genetic and epigenetic alterations. This book, comprised of four chapters, introduces recent topics regarding colorectal cancer, and provides recent highlighted information concerning prevention, diagnosis and treatment. This book will be of interest to undergraduate and graduate students, biomedical researchers, and medical doctors focused on the fields of molecular and cellular biology, medical sciences, and clinical challenges.

The first edition of Comorbidities in Chronic Kidney Disease is focused on the main clinical syndromes associated with renal failure. Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are characterized by a wide spectrum of comorbidities, potentially complicating patients clinical outcomes. In this volume, both editor and authors have planned a complete review of the main clinical syndromes associated with renal injury and failure. The first chapter is dedicated to epidemiological aspects of chronic kidney disease, and also introduces risk factors and associated comorbidities. Arterial hypertension and cardiovascular diseases are actually accountable as major risk factors for developing renal disease, and the next chapter is mainly focused on the latest trials in this field. The following chapter is dedicated to pathophysiology, diagnosis and treatment of dyslipidemia and atherosclerosis in patients with declined renal function. The subsequent chapter is exhaustively focused on the clinical features of secondary hyperparathyroidism and the diseases complications on kidneys, bone, vessels and heart, from early laboratory findings to severe vascular and heart valvular calcifications. The section that succeeds reflects on secondary anemia and consequent cardiorenal anemia syndrome with particular attention on the latest treatment schedules. Coronary artery disease is also discussed, especially for those concerned with clinical features and laboratory diagnosis in chronic kidney disease patients with impaired clearance of coronary acute syndrome biomarkers. Cardiorenal syndrome and sudden cardiac death are well-established clinical aspects in CKD patients, and they are discussed both in terms of pathophsysiological and clinical features. The book finally ends with two sections on hepato-renal syndrome and contrast-induced nephropathy (CIN). CIN represents daily challenges for all nephrologists because due to the large amounts of instrumental diagnostic tests and an increasing number of chronic kidney disease patients involved. This volume could be appreciated both by nephrologists and all clinicians involved in chronic patients management due to schematic and practical editing and form.

Kidney cancer is the 10th most common cancer in Europe with overall mortality rates increasing until the late 1980s and early 1990s and thereafter, stabilised. Until recently, renal cell carcinoma (RCC) was thought to represent a monomorphic disease; however, modern genetic characterisation has demonstrated different subtypes with specific cell types and molecular metabolism. Imaging diagnostic methods are basic for staging and for new treatment strategies. Moreover, tumour biopsy has been reintroduced in the diagnostic armamentarium, mainly in patients with small masses but also when disseminated tumours need to be treated with new target therapies. Although TNM stage, Fuhrman grade and Eastern Oncology Group (ECOG) performance status are the most recognised prognostic factor in RCC, active research continues to determine new prognostic factors to classify different risks for death from RCC. Laparoscopy has gained widespread popularity because of a less morbidity and a faster post-operative convalescence. Partial laparoscopic nephrectomy is a demanding operation that can be made depending on the experience of the surgeon, the size or location of the tumour in the kidney. New robotic approaches are being introduced for nephron sparing surgery. Conversely, cardiac bypass can be necessary for resection of tumours with thrombus extending into the inferior vena cava above the level of hepatic veins. With the advent of modern ablative energies (cryotherapy or radiofrequency) for renal tumours in selected patients with percutaneous or laparoscopic techniques, it is now possible to achieve long cancer specific survival with decreased morbidity. A need for standardisation of follow-up after surgery with lifelong protocols has been recognised in last years. Finally, angiogenesis inhibitors have demonstrated a high probability of disease control in patients with metastatic renal carcinomas. Their indication as adjuvant in local advanced tumours as well as the role of nephrectomy in patients with metastatic disease is being evaluated in current clinical trials.

Nephrolithiasis is the third most common diagnosis involving the urinary tract, exceeded only by urinary tract infections and prostate conditions. Uric acid nephrolithiasis accounts for 5-10 % of all kidney stones in the general population in the United States (US) and is noted to be increasing in other parts of the world like Japan, previously known to have a low incidence of this condition. This increase is attributable, at least in part, to westernised eating habits. Other factors which influence development of kidney stones include age, sex and ethnicity. This book discusses in further details, the risk factors, treatment options and ways to prevent nephrolithiasis.

This multi-author book is an important contribution to the fields of nephrology and nephropathology, which is primarily focused on the discussion of the pathogenesis and pathology of nephrotic syndrome. A few primers are available on this subject, but those can be considered as reference works and not suitable for daily or bedside use. The present book has been written with a view to fill this void, at least partially. It is written by many practicing nephrologists and nephropathologists from different parts of the world, in particular, from developing countries. The book not only discusses the etiology and pathology of the disorder but also addresses the new developments and updates on the pathogenesis of nephrotic syndrome, which is the most common clinical manifestation of medical renal disorders in nephrological practice throughout the world. The book is handy and can be used in the office, classroom and by the patient bedside. It will prove very useful for the beginners in the field of nephrology and nephropathology. The book has been written in easy English, and is very well illustrated to enable easy comprehension and assimilation of the knowledge and information contained in it.

Vesicoureteral reflux (VUR) is defined as the retrograde flow of urine from the bladder to the upper urinary tract. It is a common urological entity among children and it is usually diagnosed in the prenatal period or after episodes of febrile urinary tract infection. Reflux can also be found in post-pubertal patients, but it is less common in this population. Pyelonephritis is an upper urinary tract infection involving the kidneys with an incidence in the USA as high as 250.000 cases per year. Most episodes of pyelonephritis are generally considered to be uncomplicated in healthy non pregnant adults. Different risk factors have been identified, such as diabetes, urinary tract obstruction, presence of an indwelling urethral catheter, stent or nephrostomy, functional or anatomic abnormalities of the urinary tract, renal transplantation, immunosuppressive therapy and pregnancy. This book discusses the causes, prevalence and treatment approaches of both VUR and pylonephritis.

Urolithiasis is one of the oldest documented medical ailments with archeological evidence showing that humans have suffered from kidney and bladder stones for centuries. Urolithiasis is a common multifactorial problem with multi-effect on the patients' quality of life and an economic burden on the individual and the health system of the country. Various intrinsic and extrinsic factors are associated with the risk for stone formation. Among intrinsic factors are race, sex, and genetics. Finding the cause of urolithiasis or establishing it early in life will reduce the consequence and complications of kidney stone disease and hence reduction of the cost in the treatment by establishing preventative measures in addition to patient education. Genetic factors play an important role in the etiology of urolithiasis as a polygenic (common) or monogenic (rare) forms, however its knowledge and early diagnosis is important for achieving the goals of reducing patient suffering as well as economic burdens that inevitably follow a diagnosis. This book discusses the symptoms, management and prevention strategies of urolithiasis.

Glomerulonephritis is a term referring to direct injury of the glomeruli with resulting disturbances of normal glomerular function, progressively leading to renal failure. Glomerular diseases are classified as primary, where glomerular damage is the prime disturbance, with extrarenal manifestations as a result of renal impairment, and secondary, following systemic disorders, infections or exposure to certain drugs. Although noteworthy progress has been made in the past years in the symptomatic and specific treatment, therapy of both primary and secondary glomerulonephritis can be challenging. Management of these patients requires early diagnosis, expert knowledge of the immunosuppressive agents and other drugs currently available for the treatment of each glomerulonephritis, consideration of possible adverse reactions to these drugs, alternative therapeutic strategies in cases of hyporesponsiveness or non-responsiveness of the patient to the treatment, and possible relapses of the disease. This book reviews knowledge of the main primary and secondary glomerulonephritis, with emphasis on current therapeutic strategies and practical recommendations. Glomerulonephritis are grouped according the presence or absence of proliferative histological alternations into primary and secondary proliferative and non-proliferative types. Each chapter deals with etiopathogenesis, epidemiology, pathology, clinical manifestations, natural history and therapeutic options of the commonest primary and secondary glomerular diseases, with exception the last chapter that covers inherited diseases with renal involvement. An atlas of the pathology of the glomerular diseases discussed completes this work.

Hemolytic uremic syndrome (HUS) is characterized by the triad non-immune micro-angiopathic hemolytic anaemia, thrombocytopenia and acute renal failure. The disease mainly affects children one to ten years of age. It begins after an incubation period of 4 to 7 days with abrupt onset of bloody diarrhoea and abdominal pain. Two to ten days later, microangiopathy, haemolytic anaemia, thrombocytopenia, and acute renal failure develop. HUS microangiopathy can involve almost any organ, but damage to kidneys and central nervous system cause the most severe clinical problems. This book discusses the symptoms, the treatment options and prognosis of HUS.

Acute kidney injury (AKI), defined as an abrupt decrease in renal function over a period of hours to days, is a common complication among hospitalised patients with different acute diseases. Its incidence has been increasing in recent years and is reported to be very high especially in the acute settings. Since clinical signs and symptoms of acute renal damage are not specific, it is difficult to promptly distinguish AKI at the time of patient presentation. Currently the diagnosis of AKI requires serial assessment of laboratory tests over a period of several days, and is based mainly on the evaluation of serum creatinine (sCr) and decrease in urine output as supported by Risk, Injury, Failure, Loss, and End-Stage Kidney Disease (RIFLE) criteria, Acute Kidney Injury Network (AKIN) criteria, and the recent Kidney Disease: Improving Global Outcomes (KDIGO) practice guidelines for AKI. Such a need for repeated sCr evaluations and monitoring of urinary output for too long time after admission could therefore result in a diagnostic delay. With delays in diagnosis, clinicians miss opportunities to start appropriate treatment to minimise damage, and patients incur more severe AKI with subsequent greater risk of developing progression of renal damage leading to chronic kidney disease (CKD), dialysis and increased risk of severe cardiovascular diseases and death.
