Chelation Therapy in the Treatment of Metal Intoxication presents a practical guide to the use of chelation therapy, from its basic chemistry, to available chelating antidotes, and the application of chelating agents. Several metals have long been known to be toxic to humans, and continue to pose great difficulty to treat. These challenges pose particular problems in industrial settings, with lead smelting known to be associated with hemopoietic alterations and paralyses, and the inhalation of mercury vapor in mercury mining being extremely detrimental to the central nervous system. Clinical experience has demonstrated that acute and chronic human intoxications with a range of metals can be treated efficiently by administration of chelating agents. Chelation Therapy in the Treatment of Metal Intoxication describes the chemical and biological principles of chelation in the treatment of these toxic metal compounds, including new chelators such as meso-2,3-dimercaptosuccinic acid (DMSA) and D,L-2,3-dimercapto-1-propanesulfonic acid (DMPS). - Presents all the current findings on the potential for chelation as a therapy for metal intoxication - Presents practical guidelines for selecting the most appropriate chelating agent - Includes coverage on radionuclide exposure and metal storage diseases - Describes the chemical and biological principles of chelation in the treatment of toxic metal compounds

Volume 19, entitled Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic of the series Metal Ions in Life Sciences centers on the role of metal ions in clinical medicine. Metal ions are tightly regulated in human health: while essential to life, they can be toxic as well. Following an introductory chapter briefly discussing several important metal-related drugs and diseases and a chapter about drug development, the focus is fi rst on iron: its essentiality for pathogens and humans as well as its toxicity. Chelation therapy is addressed in the context of thalassemia, its relationship to neurodegenerative diseases and also the risks connected with iron administration are pointed out. A subject of intense debate is the essentiality of chromium and vanadium. For example, chromium(III) compounds are taken as a nutritional supplement by athletes and bodybuilders; in contrast, chromate, Cr(VI), is toxic and a carcinogen for humans. The benefi cial and toxic effects of manganese, cobalt, and copper on humans are discussed. The need for antiparasitic agents is emphasized as well as the clinical aspects of metal-containing antidotes for cyanide poisoning. In addition to the essential and possibly essential ones, also other metal ions play important roles in human health, causing harm (like the metalloid arsenic, lead or cadmium) or being used in diagnosis or treatment of human diseases, like gadolinium, gallium, lithium, gold, silver or platinum. The impact of this vibrant research area on metals in the clinic is provided in 14 stimulating chapters, written by internationally recognized experts from the Americas, Europe and China, and is manifested by approximately 2000 references, and about 90 illustrations and tables. Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic is an essential resource for scientists working in the wide range from pharmacology, enzymology, material sciences, analytical, organic, and inorganic biochemistry all the way through to medicine ... not forgetting that it also provides excellent information for teaching.

Metal chelators are emerging as versatile tool with many medical applications. Their versatility allows them to be used in chelation therapy for treating diseases caused by toxic and heavy metal poisoning, chelating agents are capable of binding to toxic metal ions to form complex structures which are easily excreted from the body removing them from intracellular or extracellular spaces. In addition, metal chelators can also be applied as contrast agents in MRI scanning. Metal Chelation in Medicine provides a clear and timely perspective on the role of chelating agents in the management of metal intoxications and storage diseases. Written by leaders in the field of chelators, this publication is at the cutting-edge of the subject. It covers a broad range of topics such as the use of metal chelators in non-invasive assessment of brain iron overload, and the treatment of systemic iron overload and neurodegenerative diseases. As such it is particularly valuable to clinicians treating metal poisonings and metal storage diseases. However, it is also a useful text for researchers, industry professionals and university students with a specific interest in medicinal chemistry, chelation, metal ions, imaging and non-invasive techniques.

Focusing on the practical use of N-Acetyl-Cysteine (NAC) in medicine, this book provides a comprehensive review of the basic biological and clinical studies documenting its benefits in treating medical disease. NAC is perhaps best known as an antidote for acetaminophen, but its therapeutic effect in a wide range of medical diseases has recently been realized. In addition to its well recognized use in radiological contrast prophylaxis for renal disease and pulmonary disorders, studies have suggested significant promise in psychiatric and neurological disorders such as addiction, Alzheimer’s disease, ataxia, autism, bipolar disorder, depression, epilepsy, neuropathy, obsessive-compulsive disorder, schizophrenia, traumatic brain injury and trichotillomania in addition to promising studies in audiology, cardiology, exercise physiology, gastroenterology, hematology, infectious disease, infertility and ophthalmology. Given the promising studies for a wide range of medical conditions, coupled with a excellent safety profile, the potential for NAC in the treatment of human disease appears considerable. Dr Leonore A Herzenberg from Stanford University, a pioneer of redox physiology and the use of NAC, provides a succinct history of the development of the therapeutic use of NAC for medical disease. This is followed by a series of basic science chapters outlining the role of NAC in important physiological processes, including modulation of dopamine and glutamate neurotransmitter systems, redox and mitochondrial metabolism, apoptosis and inflammation. The last section of the book is dedicated to clinically oriented chapters that comprehensively review the literature on medical disorders in which NAC has been found to be effective, including toxicity and cardiovascular, gastrointestinal, neurological, psychiatric, pulmonary and renal disorders. Each chapter reviews the theoretical biological mechanisms of NAC for the specific diseases reviewed, rates the clinical studies using a standardized criteria in order to provide an objective level of evidence and grade of recommendation for the use of NAC for specific medical conditions and outlines the ongoing clinical trials examining NAC for the treatment of specific diseases. Final chapters review the clinical evidence verifying that specific theoretical biological mechanisms are actually being targeted by NAC in medical disease. Studies on the pharmacology, formulation and potential adverse effects of NAC are also reviewed. A final chapter synthesizes the clinical studies to suggest that the effectiveness of NAC may signal a new basic physiological disorder, glutathione deficiency, which may be an important pathophysiological mechanism of many diseases.
