The renewal of interest in peritoneal dialysis as a treatment modality for patients with end-stage renal disease was stimulated by the report of Po- povich and his colleagues in 1976 on the technique of CAPD. With the in- troduction of commercial dialysate-containing plastic bags, which mark- edly reduced the incidence of peritonitis, the use of CAPD as a primary treatment modality has increased significantly. At the present time, more than 12% of the patients undergoing dialysis in the United States are utiliz- ing CAPD; however, the use of CAPD among pediatric patients is con- siderably greater. The First International Symposium on CAPD in Children was orga- nized in order to gather together experts with experience in treating chil- dren undergoing CAPD in an attempt to exchange current information on the utilization of this emerging technique in children. Since pediatric pa- tients comprise a small percentage of the CAPD population and since lim- ited data were available concerning specific methodology and complica- tions of CAPD in children, it was hoped that an international symposium would provide a forum for an exchange of experience that would ultimate- ly lead to better adaptation and increased utilization of this technique.

The mechanisms by which animals regulate the volume and composition of their body fluids has long had a particular fascination for students of biology. As a consequence, the subject can lay claim to an impressive record of ground breaking scientific achievements as well as a provocative body of philosophical speculation concerning the role of the system in the origin and evolution of life. Indeed, the entire concept of homeostasis on which so much of o r current biologic thinking is based, derives from Claude Bernard's pioneering exploration of the forces that determine the composition of this 'internal sea'. Other seminal achievements credited to this area of inquiry include the first description of a genetically transmitted human disease (familial neurogenic diabetes insipidus); the first isolation sequencing and synthesis of a peptide hormone (vasopressin and oxytocin); the first demonstration of peptide hormone synthesis by way of a larger protein precursor; the first description of resistance to the biologic actions of a hormone (nephrogenic diabetes insipidus); and the conceptual realization of the unique counter-current mechanism that permits concentration of the urine. This record of far reaching and fundamental advances has been distinguished by many fruitful inter actions between clinical and basic science."

Ethical Problems in Dialysis and Transplantation presents an overview of issues with which nephrologists and decision makers are confronted in their daily practice. The search for a universal system of ethics and theories of justice are addressed. Furthermore the work provides a normative ethical discussion of ways of distributing resources with a view to selection and commercialization. Others chapters discuss a philosophical and religious analysis of stopping treatment and the clinical and ethical aspects of stopping treatment in dialysis. Different views from different countries on the subject of dialysis and transplantation are covered including the views expressed by contributors from India, Africa, Japan, Great Britain and China. The work presents the clinician with a guide to the ethical considerations underlying the treatment of dialysis and renal transplantation patients.

Decoding the significance of proteinuria as an indicator of severity or prognosis in kidney disease is a stimulating challenge to students and practitioners of nephrology. Sir Richard Bright in 1827 associated pro with the disease that bears his name. In the subsequent more teinuria than a century and a half, however, the meaning of the linkage between proteinuria and renal disease remains elusive. Proteinuria is discovered on routine urinalysis in about 10 million Americans, most of whom express no symptoms of kidney disease, each year. From the studies of Robinson (updated in these pages), we know that proteinuria, per se, can be present for 20 years without change in re nal function, as described in orthostatic proteinuria. By contrast, pro teinuria may be the harbinger of swift kidney destruction, rarely cul minating in clinical collapse, a syndrome typifying "malignant proteinuria" as detailed herein by Avram. Although proteinuria is ubiquitous, an orderly management strategy for rational handling of proteinuria of less than nephrotic range is lack ing. Separation of tubular proteinuria and transient proteinuria of fever is now possible routinely. This book provides a record of the contribu tions of investigators and clinicians whose work forms the substrate for production of understanding and, ultimately, marching orders for prac titioners seeking optimized management for their proteinuric patients."

More than half a million people worldwide are now sustained by renal replacement therapy, mainly hemodialysis at a cost exceeding USD 30 billion per year. Each case of ESRD that is delayed or prevented saves funds that may be applied to other aspects of health care. Edited by an internationally renowned nephrologist, Prognosis for Kidney Disorders provides a timely summary of exciting work in progress directed toward renoprotection and of ultimate interdiction of ESRD.
Suitable for researchers and clinicians, Dr. Morrell Michael Avram has collected and commented on promising initiatives likely to enter everyday practice in the immediate future. Suitable for renal trainees, experienced kidney doctors, nurses, nutritionists and cardiologists.

Is the nephrology community facilitating excess cardiovascular deaths in patients with kidney failure and anemia by treating to a subnormal hematocrit? Why have clinicians and nephrologists permitted health insurance companies and the government to decide when anemia therapy should begin in persons with progressive kidney failure? Is iron the only variable that can be manipulated to maximize response to recombinant erythropoietin? Are we using too much intravenous iron in kidney failure patients, and is oral iron supplementation worthless in sustaining iron stores during long-term erythropoietin treatment? When does left ventricular hypertrophy begin to emerge in patients with progressive renal disease and is there convincing evidence that anemia is a significant cause of LVH in this setting? Is darbepoetin alfa, a new novel, long-acting erythropoietin, really superior to recombinant erythropoietin? This book is a compilation of proceedings from a conference in Brooklyn convened to address these and other controversial and unresolved issues in renal anemia management.

Cardiovascular complications are not only responsible for more than half of our patients' mortality, they also represent the bulk of everyday problems in a dialysis unit. Yet, the space allocated to them in the major textbooks covers only 2-8% of their total content. The origins of this book lie in many years of day-to-day care of dialysis patients. It gradually became clear to the author that systematic application of well-known pathophysiological principles could improve patients' conditions beyond expectations. More importantly, it appeared that world literature was mainly concerned with evaluating risk factors and that efforts to improve prognosis were concentrated on urea removal. It is important, therefore, to notice that Volume Control', the central issue of this book, is not incorporated into the Adequacy' concept. While primarily intended for dialysis doctors, the author sincerely hopes that dialysis nurses, who carry the lion's share of day-to-day responsibility for dialysis patients, will also find this book a useful and practical guide to dialysis treatment.

Glomerulonephritis has always been regarded as a complex subject. Different forms o f the disease c a n cause death in a matter o f weeks, nephrotic syndrome which might or might not prove responsive to steroid therapy, or no symptoms a t all. Improved pathological te- niques and criteria have permitted a more accurate diagnosis and prognosis to be established for many patients. With increased und- standing of the immunological mechanisms involved it has become apparent that many patients presenting with a variety of symptoms and signs m a y have glomerulonephritis as their primary pathological process. This book examines the clinical, pathological and aetiological factors involved in the common forms o f glomerulonephritis. Each chapter has been written by a recognized expert in the field and provides information of relevance and practical importance to the average clinician. The developments of the last decade have emp- sized that glomerulonephritis is no longer a matter only for the nephrologist but a subject o n which all clinicians should be well informed.

The behavior of the kidney in normal pregnancy, as well as in complicated pregnancy, is a very interesting, but still in many ways an unknown topic in renal medicine. It is undoubtedly difficult to determine, even in normal women, the behavior of renal hemodynamics throughout gestation, since the fear of impairing a new life (i.e., the fetus's life) will limit, for ethical reasons, the use or the frequent repetition of diagnostic tests on the mother. On the other hand, the study of complicated pregnancy even for diagnostic purposes (for planning adequate treatment), except in a few countries that are known for the advanced health education of the population, has to face serious difficulties. First of all, pregnant women usually seek the help of an obstetrician when gestation is already in an advanced stage. This makes it difficult to determine when and how asymptomatic signs of any disease discovered during pregnancy have first occurred. A second difficulty is that frequently the patient does not know whether a given disease has preceded pregnancy. Pregnancy is a condition of young women, and a young woman frequently has never seen a physician; thus, no urine analysis or blood tests have been performed before the gestation. Not infrequently, even blood pressure has never been measured. This will make it difficult to classify hypertension discovered in late pregnancy as pregnancy-induced hypertension or as chronic hypertension in pregnancy.

aintaining extracellular calcium concentrations within a narrow range is critical for the survival of most vertebrates. PTH, together with vitamin D, responds to hypocalcemia to increase extracellu M lar calcium levels, by acting on bone, kidney and intestine. The recent intro duction of PTH as a major therapeutic agent in osteoporosis has directed renewed interest in this important hormone and in the physiology of the parathyroid gland. The parathyroid is unique in that low serum calcium stimulates PTH secretion. As hypocalcemia persists, there is also an increase in PTH synthesis. Chronic hypocalcemia leads to hypertrophy and hyper plasia of the parathyroid gland together with increased production of the hormone. Phosphate is also a key modulator of PTH secretion, gene expres sion and parathyroid cell proliferation. Understanding the biology of the parathyroid as well as the mecha nisms of associated diseases has taken great strides in recent years. This book summarizes the molecular mechanisms involved in the function of the para thyroid gland. The first chapter reviews the development of the parathyroid gland and the genes involved in this process as identified using genetically manipulated mice. Then the biosynthetic pathway of PTH from gene ex pression to its intracellular processing and the sequences in the gene control ling its transcription as well as those regulating mRNA processing, stability and translation are described."

A large number of chemical agents are known which affect blood and blood-forming organs. The purpose of this volume is to review the sig- nificant advances made over the past several years regarding such chemical agents. The purification, biological action, and therapeutic implications of several widely used hematopoietic growth factors such as interleukin 3 (IL-3 or multi-CSF), granulocyte/macrophage colony stimulating factor (GM-CSF), granulocyte colony stimulating factor (G-CSF), colony stimu- lating factor (CSF-I or M-CSF), thrombopoietin, and erythropoietin are included in this volume. These factors are important in regulating several hematopoietic cell lines such as neutrophils, monocytes, eosinophils, macrophages, megakaryocytes, platelets, and erythrocytes. People are exposed daily to numerous toxic chemical substances present in our environment which produce a suppression of erythropoiesis, myelo- poiesis, lymphocytopoiesis, and megakaryocytopoiesis. Attempts have been made in this volume to assess the therapeutic role of some of the hematopoietic factors such as erythropoietin in the anemia of end stage renal disease, as well as colony stimulating factors in other hematopoietic abnormalities. In addition, some of the chemical factors in our environment which suppress major hematopoietic lineages stimulated by erythropoietin, macrophage colony stimulating factor, granulocyte colony stimulating factor, interleukin I-alpha, interleukin I-beta, and interleukins 2, 3, 4, 5, 6, 7, and 9 are also included. An updating of the mechanism of action of each of these factors on the major hematopoietic lineages is covered.

Secondary forms of hypertension are not uncommon in clinical prac tice, but they are often overlooked or forgotten by clinicians in many fields of medicine. Dr. George Mansoor' s volume on Secondary Hyper tension is an important contribution to the field of clinical hypertension and vascular diseases, since it brings up to date the numerous diagnostic and therapeutic advances in the evaluation for secondary types of hyper tension. In the past, textbooks usually stated that an etiology could be determined in less than 5% of patients presenting with newly diagnosed hypertension. We now know this is far too low a proportion (e.g., pri mary hyperaldosteronism alone may account for hypertension in 5% of patients presenting with chronic elevations in blood pressure). Secondary Hypertension has been thoughtfully organized into chap ters evaluating screening and diagnosis, as well as medical and/or sur gical intervention of the well-known etiologies of secondary hypertension in adults and children. Additional coverage is given to such exogenous or lesser appreciated causes of secondary hypertension as obstructive sleep apnea and drugs. These sections make this book novel because in the past little attention has been paid to the effects of noncar diac drugs that interfere with antihypertensive therapy or to exogenous substances that might induce refractory hypertension."

A special effort was made to recruit contributors among the most important scientific authorities in their respective fields: we are grateful to Drs. Cameron, Lamm, Isemberg, Meyrier, Niaudet, Brynger, Lundgren, Fauchald, Cockburn, Gotch, Kopple, Cheung and Horl for having accepted our invitation. We are also indebted to all other authors who participated in the meeting and submitted their original papers for publication. I.

During recent decades, it has been firmly documented that chlamydiae are com mon and important pathogens in humans and animals. In humans, chlamydiae are known to cause trachoma (which is still one of the major blinding diseases in the world) and are also one of the most common etiological agents of sexually transmitted diseases and the sequelae thereof, such as infertility. In the last few years, it has also become evident that chlamydiae, i.e., the so-called TWAR agents, are common respiratory tract pathogens. Chlamydiae are also important pathogens in birds and lower mammals, in whom they cause a variety of infectious conditions, a spectrum which has in creased every year. Some of these infections occur as zoonoses, e.g., psit tacosis/ornithosis and, as recently discovered, abortion. Know ledge of the molecular biology and immunobiology of chlamydiae has expanded rapidly during recent years. Insight into the pathophysiology of chla mydial infections has also increased, and new methods for the diagnosis of chlamydial infections have been introduced. The importance of establishing control and preventive programs for chla mydial infections has become obvious in order to combat the present chlamydial epidemic. We hope that this book can usefully serve those who want to increase their general knowledge of Chlamydia and that it can act as a handbook and reference source for those involved in chlamydial research as well as for those working with chlamydial infections in medical and veterinary clinical disciplines, includ ing clinical laboratories."

Almost every practising doctor will admit to difficulty in knowing how best to investigate, treat and advise the pregnant patient with renal problems. These doubts and difficulties may be exacerbated if the patient seeks pre-pregnancy advice - would a possible pregnancy cause a deterioration in renal function, what are the risks of the pregnancy for mother and baby? As the general public become more informed on medical matters these questions are being asked more frequently and doctors must be prepared to offer advice which is based on detailed factual knowledge. This book examines some of these increasingly common clinical problems. Each chapter has been written by a recognized expert in the field and provides the type of specific information now expected by discerning patients. The advances in treatment of the last decade clearly indicate that a knowledge of pregnancy and renal disorders is essential for doctors in many branches of medical practice.

When the kidney fails its intended mission to manage the body 's waste products, physicians must perform multi-level and simultaneous adjustments to replicate kidney function. The management of the body 's absorption, reabsorption, utilization and excretion of calcium and phosphate requires constant fine tuning. This book provides an overview of the state-of-the-art clinical and basic science aspects of abnormal calcium and phosphate metabolism and its management.

Over the years, the Belfast Renal Transplant Unit has acquired considerable experience in all aspects of renal transplantation which have led to excellent results. The team working in the Belfast Renal Transplant Unit has built up an outstanding reputation which has become widely known. This volume is a comprehensive, practical reference work for senior medical students and nurses as well as for the established nephrologist and transplantation surgeon. It provides a clear and concise picture of the care needed by patients who are being prepared for renal transplantation or who have recently received a kidney transplant.

Ethical rational, facts, and center techniques for choosing kidney donors all in one volume. This is the first book of its kind, devoted solely to preoperative issues for living kidney donors and those who counsel them. The eight chapters are devoted to vital areas that are comprehensively addressed by experienced professionals. The book presents a unified ethical and factual approach that is essential for all transplant centers to understand. It is a readable and understandable ethical foundation for living kidney donation that is free of jargon. It includes balanced, hard to find factual summaries that are essential for acceptable kidney donor counseling. As transplant centers increasingly turn to living kidney donors, this book is an essential step forward in the field.
The book will appeal to transplant physicians and surgeons, transplant coordinators and social workers, nephrologists who have patients on dialysis or who evaluate potential living kidney donors and to potential living kidney donors and their recipients. As a practical application of medical ethics to an important field, it will be of interest to medical ethicists as well.

Glomerulonephritis is one of the commonest causes of end-stage renal failure worldwide. Although there have been considerable advances in the management of renal failure by dialysis and transplantation, there has been relatively little progress in its prevention. This volume sets out to review current practice in the treatment of glomerulonephritis, which is aimed both at controlling the clinical manifestations, e.g. nephrotic syndrome, and at preventing the progression to renal failure. The term glomerulonephritis covers a wide range of conditions with different immunological, histological and clinical features. This volume therefore starts with reviews of the immunology and pathology of different types of glomerulonephritis. This is followed by detailed consideration of the treatment of the commoner primary and secondary forms of the disease. There are separate chapters on special circumstances, such as glomerulonephritis in pregnancy or following renal transplantation. In each chapter, attempts are made to review the evidence for the effectiveness of treatment, based on controlled trials, immunopathological principles and the authors' considerable experience. Although some aspects of the treatment of glomerulonephritis can be found in the standard texts on renal disease, this volume provides an up-to-date, thoroughly referenced, and practical guide to management. As such, it should be of value to nephrologists and general physicians, including those in training, and to postgraduate students of nephrology.

The aquaporin field has matured at an exceptionally fast pace and we are at the verge to develop serious strategies to therapeutically modulate aquaporin function directly or via regulatory networks. Key prerequisites are available today: i. a considerable (and growing) number of aquaporin crystal structures for the rational design of inhibitory molecules, ii. elaborate molecular dynamics simulation techniques for theoretical analyses of selectivity mechanisms and docking experiments, iii. comprehensive data on aquaporin immunohistochemistry, iv. aquaporin knockout animals for physiological studies, and v. assay systems for compound library screenings. The structure of this volume on aquaporins follows the points laid out above and thus covers the developments from basic research to potential pharmacological use. Situated between pharmacology textbooks and recent scientific papers this book provides a timely overview for readers from the fundamental as well as the applied disciplines.

Kidney Transplantation: A Guide to the Care of Transplant Recipients is an easy to read, up to date, clinical resource written by experts in the field of kidney transplantation. The book explains how donors and recipients are selected for transplantation, how the surgical procedure is performed, and how the experts recognize and treat rejection.

Clearly illustrated chapters show how the immune system works in the setting of transplantation and how immunosuppressive medications prevent rejection of the transplanted kidney; knowledge essential for the proper care of the transplant recipient.

The acute and long-term care of the patient is described from the perspective not only of proper immunosuppressive medication management, but also from the perspective of comorbidities most common to transplanted patients, including cardiovascular disease, diabetes mellitus, infectious diseases, malignancies, and bone disease. Special issues that impact the care of the transplant recipient, such as unusual donor sources, nonadherence and insurability are also addressed in separate chapters.

This comprehensive practical guide to transplant patient care is an essential source for the practicing community nephrologist that cares for transplanted patients, as well as medical and surgical residents and fellows in training.

Clear illustrations as well a therapeutic algorithms complement the text, making this an easy to read, up to date source on the clinical practice of kidney transplantation.
