Overview Of Ketosis In Cattle

(Acetonemia, Ketonemia) By Thomas H. Herdt, DVM, MS, DACVN, DACVIM, Professor, Department of Large Animal Clinical Sciences and Diagnostic Center for Population and Animal Health, Michigan State University Ketosis is a common disease of adult cattle. It typically occurs in dairy cows in early lactation and is most consistently characterized by partial anorexia and depression. Rarely, it occurs in cattle in late gestation, at which time it resembles pregnancy toxemia of ewes (see Pregnancy Toxemia in Ewes and Does). In addition to inappetence, signs of nervous dysfunction, including pica, abnormal licking, incoordination and abnormal gait, bellowing, and aggression, are occasionally seen. The condition is worldwide in distribution but is most common where dairy cows are bred and managed for high production. Etiology and Pathogenesis: The pathogenesis of bovine ketosis is incompletely understood, but it requires the combination of intense adipose mobilization and a high glucose demand. Both of these conditions are present in early lactation, at which time negative energy balance leads to adipose mobilization, and milk synthesis creates a high glucose demand. Adipose mobilization is a Continue reading >>

    This makes no sense. If this hypothesis that fat caused insulin resistance were true, and that lowering dietary fat would increase insulin sensitivity, we would be curing type 2 diabetes with low fat diets. In fact it's ketogenic diets that get people off insulin and diabetic medications.

    Because the muscle tissues become more adept at using BHB, GLUT receptors are down-regulated at the muscle level as a person becomes more keto-adapted. Although we still have much to learn about the keto-adapted state, we know that this occurs more prominently in the muscle tissues than in the gut and brain. This fascinating glucose sparing phenomenon, has been interpreted by some as “worsening insulin resistance.”

    Despite all the success you might have had with the Primal way of life, doubts can still nag at you. Maybe it's something you read, or something someone sa

    Going very low carb – to around or below 10% of calories, or full-blown ketogenic – can induce “physiological” insulin resistance. Physiological insulin resistance is an adaptation, a normal biological reaction to a lack of dietary glucose. As I’ve said in the past, the brain must have glucose. It can use ketones and lactate quite effectively, thus reducing the glucose requirement, but at the end of the day it still requires a portion of glucose. Now, in a low-glucose state, where the body senses that dietary glucose might not be coming anytime soon, peripheral insulin resistance is triggered. This prevents the muscles from taking up “precious” glucose that the brain requires. The brain’s sensitivity to insulin is preserved, allowing it to grab what glucose it needs from the paltry – but sufficient – levels available to it.

Ketosis: What Is Ketosis?

Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to av Continue reading >>

What is CLINICAL PATHWAY? What does CLINICAL PATHWAY mean? CLINICAL PATHWAY meaning - CLINICAL PATHWAY definition - CLINICAL PATHWAY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6Uu... A clinical pathway, also known as care pathway, integrated care pathway, critical pathway, or care map, is one of the main tools used to manage the quality in healthcare concerning the standardisation of care processes. It has been shown that their implementation reduces the variability in clinical practice and improves outcomes. Clinical pathways aim to promote organised and efficient patient care based on evidence-based medicine, and aim to optimise outcomes in settings such as acute care and home care. A single clinical pathway may refer to multiple clinical guidelines on several topics in a well specified context. A clinical pathway is a multidisciplinary management tool based on evidence-based practice for a specific group of patients with a predictable clinical course, in which the different tasks (interventions) by the professionals involved in the patient care are defined, optimized and sequenced either by hour (ED), day (acute care) or visit (homecare). Outcomes are tied to specific interventions. The concept of clinical pathways may have different meanings to different stakeholders. Managed care organizations often view clinical pathways in a similar way as they view care plans, in which the care provided to a patient is definitive and deliberate. Clinical pathways can range in scope from simple medication utilization to a comprehensive treatment plan. Clinical pathways aim for greater standardization of treatment regimens and sequencing as well as improved outcomes, from both a quality of life and a clinical outcomes perspective. Clinical pathways (integrated care pathways) can be seen as an application of process management thinking to the improvement of patient healthcare. An aim is to re-center the focus on the patient's overall journey, rather than the contribution of each specialty or caring function independently. Instead, all are emphasised to be working together, in the same way as a cross-functional team. More than just a guideline or a protocol, a care pathway is typically recorded in a single all-encompassing bedside document that will stand as an indicator of the care a patient is likely to be provided in the course of the pathway going forward; and ultimately as a single unified legal record of the care the patient has received, and the progress of their condition, as the pathway has been undertaken. The pathway design tries to capture the foreseeable actions which will most commonly represent best practice for most patients most of the time, and include prompts for them at the appropriate time in the pathway document to ascertain whether they have been carried out, and whether results have been as expected. In this way results are recorded, and important questions and actions are not overlooked. However, pathways are typically not prescriptive; the patient's journey is an individual one, and an important part of the purpose of the pathway documents is to capture information on "variances", where due to circumstances or clinical judgment different actions have been taken, or different results unfolded. The combined variances for a sufficiently large population of patients are then analysed to identify important or systematic features, which can be used to improve the next iteration of the pathway.

Clinical Diagnosis And Treatment Of Ketosis

Abstract Ketosis afflicts lactating dairy cattle of all ages, increasing during peak production years. It may occur two to three weeks prepartum to four months Postpartum.Common symptoms are diminished appetite, decreased milk, nervousness, profuse salivation, unnatural gait, licking themselves, grasping hard objects and damaging mouth, becoming explosively excited and unmanageable. clinically, animals reveal lack of alertness, eyes lack luster, rumen is hard and partially empty and noisy, feces are abnormally firm, and urine is clear, showing characteristics color responses to the Ross modification of the Rothera test. Stress factors may cause ketosis such as high production indigestion, milk fever, partial starvation, metritis, mastitis, and ovarian cysts Treatment for ketotic animals varies depending on conditions. Intravenous injection of dextrose is the author's standard treatment. Orally administered propylene glycol after initial use of dextrose or glucocorticoids has given excellent results. Intravenous or intramuscular cortisone has given extremely variable results. Intravenous or intramuscular adrenocorticotropin has given excellent results in prolonged ketosis, preceded Continue reading >>

    As usual the conventional wisdom is arse-about with cause/effect, gout etc isn't primarily caused by purine rich or high protein foods upping uric acid, it's the inability to effectively clear out uric acid which eventually form crystals in the joints and stones in the kidneys - which is from a feedback loop of inflammation, and usually there's a catalyst feature which induces it.
    If you are newish to low carb/keto and wondering about the dangers, then uric acid levels can rise substantially in the first 2-4 weeks, but they level out after 6-8 weeks. This is explained in the literature later in this thread, basically what happens is ketones compete for excretion with uric acid, but as you keto-adapt this is no longer a problem.
    The worst thing you can do is go back and forth between keto/carbs whilst you are still adapting. Either stick to it religiously for at least 2 months and adapt properly, or don't bother and save yourself some possible flare-ups.

It's a little rough -- unedited, not fact-checked, etc -- but should give you the general idea. It has some references in it, in the footnotes, but I didn't look to see what form they're in. It should help, though. Meanwhile, Loren Cordain has also written some on gout on his paleolithic diet website. You might look into that. If you post any of this, please credit it appropriately as unpublished from GCBC.

    Best,
    gt (Emphasis Mine)
    Gout and the condition known technically as hyperuricemia, or elevated levels of uric acid, are the most recent examples of this kind of institutional neglect of the potential health effects of fructose, and how pervasive it can be. Gout itself is an interesting example because it is a disease that has gone out of fashion in the last century and yet the latest reports suggest it is not only as prevalent as ever, but becoming more so. Recent surveys suggest that nearly 6 percent of all American men in their fifties suffer from gout, and over ten percent in their seventies. The proportion of women afflicted is considerably less at younger ages but still rises over 3 percent by age 60. Moreover, the prevalence of gout seems to have doubled over the last quarter century, coincident (perhaps not coincidentally) with the reported increase in obesity, and it may have increased five- or even six-fold since the 1950s, although a large portion of that increase may be due to the aging of the population. CKTK
    Until the late 17th century, when the spread of gout reached almost epidemic proportions in Britain, the disease afflicted almost exclusively the nobility, the rich and the educated, and so those who could afford to indulge an excessive appetite for food and alcohol. This made gout the original example of a disease linked to diet and over-consumption, and so, in effect, the original disease of civilization. But once gout became easily treatable, in the early 1960s, with the discovery of the drug allopuranol, clinical investigators and researchers began to lose interest. And the pathology of gout has been understood since the British physician Alfred Garrod, in the mid-19th century, identified uric acid as the causative agent; the idea being that uric acid accumulates in the circulation to the point that it falls out of solution, as a chemist would put it, and so crystallizes into needle-sharp urate crystals. These crystals then lodge in the soft tissues and in the joints of the extremities - classically, the big toe -- and cause inflammation, swelling and an excruciating pain that was described memorably by the 18th century bon vivant Sydney Smith as like walking on one's eyeballs. Because uric acid itself is a breakdown product of protein compounds known as purines - the building blocks of amino acids - and because purines are at their highest concentration in meat, it has been assumed for the past 130-odd years that the primary dietary means of elevating uric acid levels in the blood, and so causing first hyperuricemia and then gout, is an excess of meat consumption.
    The actual evidence, however, has always been less-than-compelling: Just as low cholesterol diets have only a trivial effect on serum cholesterol levels, for instance, and low-salt diets have a clinically insignificant effect on blood pressure, low-purine diets have a negligible effect on uric acid levels. A nearly vegetarian diet, for instance, is likely to drop serum uric acid levels by 10 to 15% percent CKTK compared to a typical American diet, but that's rarely sufficient to return high uric acid levels to normality, and there is little evidence that such diets reliably reduce the incidence of gouty attacks in those afflicted. Thus, purine-free diets are no longer prescribed for the treatment of gout, as the gout specialist Irving Fox noted in 1984, "because of their ineffectiveness" and their "minor influence" on uric acid levels. Moreover, the incident of gout in vegetarians, or mostly vegetarians, has always been significant and "much higher than is generally assumed." (One mid-century estimate, for instance, put the incidence of gout in India among "largely vegetarians and teetotalers" at 7%.) Finally, there's the repeated observation that eating more protein increases the excretion of uric acid from the kidney and, by doing so, decreases the level of uric acid in the blood. This implies that the meat-gout hypothesis is at best debatable; the high protein content of meats should be beneficial, even if the purines are not.
    The alternative hypothesis is suggested by the association between gout and the entire spectrum of diseases of civilization, and between hyperuricemia and the metabolic abnormalities of syndrome x. In the past century, gout has manifested all of the now-familiar patterns, chronologically and geographically, of diseases of civilization, and so those diseases associated with western diets. European physicians in World War I, for instance, reported a reduced incidence of gout in countries undergoing food shortages. In primitive populations eating traditional diets, gout was virtually unknown or at least went virtually unreported (with the conspicuous exception of Albert Schweitzer who says he saw it with surprising frequency.) The earliest documented cases reported in Asia and Africa were in the late 1940s. And even in the 1960s, hospital records from Kenya and Uganda suggested an incidence of gout lower than one in a thousand among the native Africans. Nonetheless, by the late 1970s, uric acid levels in Africa were increasing with westernization and urbanization, while the incidence of both hyperuricemia and gout among South Pacific islanders was reportedly sky-rocketing. By 1975, the New Zealand rheumatologist B.S. Rose, a colleague of Ian Prior's, was describing the native populations of the South Pacific as "one large gouty family."?
    Gout has also been linked to obesity since the Hippocratic era, CKTK and this association is the origin of the assumption that high-living and excessive appetites are the cause. Gouty men have long been reported to suffer higher rates of atherosclerosis and hypertension, while stroke and coronary heart disease are common causes of death. Diabetes is also commonly associated with gout. In 1951, Menard Gertler, working with Paul Dudley White's Coronary Research Project at Harvard, reported that serum uric acid levels rose with weight, and that men who suffered heart attacks were four times as likely to be hyperuricemic as healthy controls. This led to a series of studies in the 1960s, as clinical investigators first linked hyperuricemia to glucose intolerance and high triglycerides, and then later to high insulin levels and insulin resistance. By the 1990s, Gerald Reaven, among others, was reporting that insulin resistance and hyperinsulinemia raised uric acid levels, apparently by decreasing uric acid excretion by the kidney, just as they raised blood pressure by decreasing sodium excretion. "It appears that modulation of serum uric concentration by insulin resistance is exerted at the level of the kidney," Reaven wrote, "the more insulin-resistant an individual, the higher the serum uric acid concentration."
    These observations would suggest that anything that raised insulin levels would in turn raise uric acid levels and might cause gout, which would implicate any high carbohydrate diet with sufficient calories. But this neglects the unique contribution of fructose. The evidence arguing for sugar or fructose as the primary cause of gout is two-fold. First, the distribution of gout in western populations has paralleled the availability of sugar for centuries, and not all refined carbohydrates in this case. It was in the mid-17th century, that gout went from being exclusively a disease of the rich and the nobility to spread downward and outward through British society, reaching near epidemic proportions by the 18th century. Historians refer to this as the "gout wave," and it coincides precisely with the birth and explosive growth of the British sugar industry and the transformation of sugar, in the words of the anthropologist Sydney Mintz, from "a luxury of kings into the kingly luxury of commoners." British per capita sugar consumption in the 17th century was remarkably low by modern standards, a few pounds per capita per year at the turn of the century, but the change in consumption over the next century and a half was unprecedented: between 1650 and 1800, following the British acquisition of Barbados, Jamaica and other "sugar islands", total sugar consumption in England and Wales increased 20- to 25-fold.?
    The second piece of evidence is much less circumstantial: simply put, fructose increases serum levels of uric acid. The "striking increase" in uric acid levels with an infusion of fructose was first reported in the Lancet in the late 1960s by clinicians from Helsinki, Finland, who referred to it as fructose-induced hyperuricemia. This was followed by a series of studies through the late 1980s confirming the existence of the effect and reporting on the variety of mechanisms by which it came about. Fructose, for instance, accelerates the breakdown of a molecule known as ATP, which is the primary source of energy for cellular reactions and is loaded with purines. (ATP stands for adenosine triphosphate; adenosine is a form of adenine, and adenine is a purine.) And so this in turn increases formation of uric acid. Alcohol apparently raises uric acid levels through the same mechanism, although beer also has purines in it. Fructose also stimulates the synthesis of purines directly, and the metabolism of fructose leads to the production of lactic acid, which in turn reduces the excretion of uric acid by the kidney and so raises uric acid concentrations indirectly by that mechanism.
    These mechanistic explanations of how fructose raises uric acid levels were then supported by a genetic connection between fructose metabolism and gout itself. Gout often runs in families, so much so that those clinicians studying gout have always assumed the disease has a strong hereditary component. In 1990, Edwin Seegmiller, one of the few veteran gout researchers in the U.S., and the British geneticist George Radda, who would go onto become director of the Medical Research Counsel, reported that the explanation for this familial association seemed to be a very specific defect in the genes that regulate fructose metabolism. Thus, individuals who inherit this defect will have trouble metabolizing fructose and so will be born with a predisposition to gout. This suggested the possibility, Seegmiller and Radda concluded, that this defect in fructose metabolism was "a fairly common cause of gout."
    As these observations appeared in the literature, the relevant investigators were reasonably clear about the implications: "since serum-uric-acid levels are critical in individuals with gout, fructose might deserve consideration in their diet," noted the Helsinki clinicians in The Lancet in 1967, and so the chronic consequences of high-fructose diets on healthy individuals required further evaluation. Gouty patients should avoid high-fructose or high-sucrose diets, explained Irving Fox in 1984, because "fructose can accelerate rates of uric acid synthesis as well as lead to increased triglyceride production." Although none of these investigators seemed willing to define what precisely constituted a high-fructose or a high-sucrose diet. Was it 50 pounds of sugar a year? 100 pounds? 150 pounds? 300 pounds? And would high-fructose diets induce gout in healthy individuals or would they only exacerbate the problem in those already afflicted? In 1993, the British biochemist Peter Mayes published an article on fructose metabolism in the American Journal of Clinical Nutrition that is now considered the seminal article in the field. (This was in the special issue of the AJCN dedicated to the health effects of fructose.) Mayes reviewed the literature and concluded that high-fructose diets in healthy individuals were indeed likely to cause hyperuricemia, and he implied that gout could be a result, as well, but the studies to address that possibility had simply never been done. "It is clear," Mayes concluded, "that systematic
    investigations in humans are needed to ascertain the precise amounts, both of fructose consumption and of its concentration in the blood, at which deleterious effects such as hyperlipidemia and hyperuricemia occur." Add to this Reaven's research reporting that high insulin levels and insulin resistance will increase uric acid levels, and it suggests, as Mayes had remarked about triglycerides, that sugar (sucrose) and high fructose corn syrup would constitute the worst of all carbohydrates when it comes to uric acid and gout. The fructose would increase uric acid production and decrease uric acid excretion, while the glucose, though its effect on insulin, would also decrease uric acid excretion. Thus, it would be reasonable to assume or at least to speculate that sugar is a likely cause of gout, and that the patterns of sugar consumption explain the appearance and distribution of the disease.
    Maybe so, but this hypothesis has never been seriously considered. Those investigators interested in gout have focused almost exclusively on alcohol and meat consumption, in part because these have historical precedents and because the implication that gouty individuals and particularly obese gouty individuals shy away from meat and alcohol fit in well with the dietary prescriptions of the 1970s onward.
    More than anything, however, this sugar/fructose hypothesis was ignored, once again, because of bad timing. With the discovery and clinical application of allopurinol in the 1960s, those clinical investigators whose laboratories were devoted to studying the mechanisms of gout and purine metabolism - James Wyngaarden's, for instance, at Duke and Edwin Seegmiller's at NIH - began focusing their efforts either on working out the nuances of allipuranol therapy, or to applying the new techniques of molecular biology to the genetics of gout and rare disorders of hyperuricemia or purine metabolism. Nutritional studies were simply not considered worthy of their time, if for no other reason than that allopuranol allowed gout suffers to eat or drink whatever they wanted. "We didn't care so much whether some particular food might do something," says William Kelley, who is a co-author with Wyngaarden of the 1976 textbook, Gout and Hyperuricemia and who started his career in Seegmiller's lab at NIH. "We could take care of the disease."
    This exodus, however, coincided with the emergence of research on fructose-induced hyperuricemia. By the 1980s, when the ability of fructose and sucrose consumption to raise uric acid levels in human subjects was demonstrated repeatedly, the era of basic research on gout had come to an end. The major players had left the field and NIH funding on the subject had dwindled to a trickle. Wyngaarden published his last research paper in 1977 and spent the years 1982 to 1989 as director of the National Institutes of Health. Kelley published his last papers on the genetics of gout in 1989, when he became dean of medicine at the University of Pennsylvania. Irving Fox, who did much of the basic research on fructose- and alcohol-induced hyperuricemia in Kelley's lab, went to work in the biotechnology industry in the early 1990s. Only Edwin Seegmiller remained interested in the etiology of gout, and Seegmiller says that when he applied to the NIH for funding to study the relationship between fructose and gout, after elucidating the genetic connection with Radda in 1990, his grant proposals were rejected on the basis that he was too old and, as an emeritus professor, technically retired. "In the 1950s and 1960s, we had the greatest clinical scientists in the world working on this disease," says Kelley. "By the 1980s and 1990s, there was no one left."
    Meanwhile, the medical journals would occasionally run articles on the clinical management of the gout, but these would concentrate almost exclusively on drug therapy. Discussions of diet would be short, perhaps a few sentences, and confused about the science. On those occasions when the authors would suggest that gouty individuals might benefit from low-purine diets, they would invariably include "sugars" and "sweets" as among the recommended foods with low-purine contents. In a few cases - a 1996 article in the New England Journal of Medicine, for instance -- the articles would also note that fructose consumption would raise uric acid levels, suggesting only that the authors had been unaware of the role of fructose in "sugars" and "sweets." Even when the New England Journal published a report from Walter Willett and his Harvard colleagues in March 2004, this same kind of nutritional illiteracy manifested itself. Willett's article had reported that men with gout seemed to eat more meat than healthy men. But Willett, who by this time was arguably the nation's most influential nutritional epidemiologist, later explained that they had never considered sugar consumption in their analysis because neither he nor his collaborators had been aware of the hyperuricemic effect of fructose. Willett's co-author, Gary Curhan, a nephrologist and gout specialist with a doctorate in epidemiology, said he might have once known that fructose raised uric acid levels, but it had slipped his mind. "My memory is not what it used to be," he said. He also acknowledged, in any case, that he never knew sucrose was half fructose.
    The addenda to this fructose-induced hyperuricemia story may be even more important. When the New England Journal of Medicine published Willett's gout study, it ran an editorial to accompany it written by the University of Florida nephrologist Richard Johnson. Over the past decade, Johnson's research has supported the hypothesis that elevating the uric acid concentration in the circulation also damages the blood vessels leading into the kidneys in such a way as to raise blood pressure directly, and so suggests that fructose consumption will raise blood pressure.
    This is another potentially harmful effect of fructose that post-dates the official reports exonerating sugar in the diet. And it is yet another mechanism by which sugar and high fructose corn syrup could be a particularly unhealthy combination. The glucose in these sugars would raise insulin levels, which in turn would raise blood pressure by inhibiting the kidney's secretion of sodium and by stimulating the sympathetic nervous system, as we discussed in an earlier chapter, and the fructose would do it independently by raising uric acid levels and so damaging the kidney directly. If this were the case, which has never been tested, it would potentially explain the common association of gout and hypertension and even of diabetes and hypertension. Johnson is only now looking into this possibility, however. Unlike Willett and his colleagues, Johnson had long been aware of the ability of fructose to raise uric acid levels, and so was studying that phenomenon in his laboratory. But it was only in the summer of 2004, he explained, three months after his NEJM editorial was published, that he realized that sucrose was half fructose and that his research of the past years was even relevant to sugar.
    ? A decade later, Thomas Benedek described the epidemiology of gout in The Cambridge World History of Human Disease this way: "Worldwide the severity and prevalence of gout have changed paradoxically since the 1940s. In the highly developed countries, as a result of the advent of effective prophylactic drug therapy, the disease is now rarely disabling. Elsewhere, however, it has become more prevalent, predominantly as a result of `improved diets.'"
    ? The economist and historian Ralph Davis estimates that the supply of sugar from the Caribbean into Britain rose from three or four thousand tons a year in the late fifteenth century to over two hundred thousand tons by the 1770s, or an increase of over fifty-fold.

    UNPUBLISHED MATERIAL FROM THE BOOK, GOOD CALORIES, BAD CALORIES BY GARY TAUBES
    The Gary Taubes half-finished article was later published to Tim Ferriss's site:
    http://www.fourhourworkweek.com/blog/2009/10/05/gout/
    Included some recent commentary that I'd not heard of before:
    Quote from: Burton Abrams
    Your gout article rightfully refers to the work of Dr. Richard Johnson, who has moved from U. Fla to U. Col in Denver. His work clearly shows that dietary fructose is processed in the body to produce uric acid, and hence raises the level of uric acid in the blood.
    But there is more to the question of why the high concentration of serum uric acid precipitates as the crystals of monosodium urate (MSU) which cause gout. Consider that most gout attacks originate while the individual is sleeping. Why? The answer is sleep apnea, which is the frequent cessation of breathing for many seconds at a time during sleep. The resulting reduction of oxygen in the blood has three effects, each of which can make MSU precipitation more likely. The first is cell catabolism, in which ATP undergoes a chain of chemical transitions which culminates in the cellular generation of excess uric acid fed into the blood. The second is that the reduced oxygen in the blood makes the blood more acidic (lower pH) so it can hold less uric acid in solution. These two effects are transient, so blood tests taken after awakening misses their peaks. The third effect is long term. Over time the chronic intermittent reduction in oxygen causes gradual reduction of kidney function, so uric acid is removed from the blood more slowly.
    So fructose ingestion raises the uric acid baseline, but sleep apnea causes it to reach an abrupt tipping point which leads to gout. I've told hundreds of gout experts about this physiology, and the only one who already knew about it was Dr. Johnson. Unfortunately, he thought it was common knowledge.
    Dr. Johnson's recent book The Fat Switch is written for general readership. It describes how fructose activates a biological switch in the body to cause it to store fat rather than burn fat. It is an excellent companion to The Four Hour Body.
    Quote from: Burton Adams
    My experience was that when I completely overcame my sleep apnea, my gout attacks ceased immediately and completely. If your Mom's CPAP machine is properly adjusted for her, and if she always uses it whenever she sleeps, I expect that her gout attacks would be greatly mitigated. Unfortunately, many sleep physicians don't recommend total adherence to CPAP usage. I think that is a big disservice to the patient.
    MSU crystals form quickly (minutes), but then dissolve very slowly (months).
    Most gout attacks last for about a week because the immune system places a protein sheath around the crystals so that they are no longer sensed by other immune system cells which activate the gout pain and inflammation. (A gout attack is initiated by the immune system chemically sensing the presence of these crystals, not by the physical fact that these crystals are needle shaped.) So a gout attack can be initiated if the sheath is ruptured, either chemically by an uricosic drug such as allopurinol or physically by undue stress on the affected joint. Sleep apnea may be the reason why the crystals are formed in the first place, but once formed they may initiate multiple gout attacks by these other means.

    So went and found more stuff by him:
    http://www.beatinggout.com/2009/04/gout-and-the-sleep-apnea-connection/
    Quote
    Gout and the Sleep Apnea Connection
    There is a frequently overlooked factor that can cause an acute increase in the concentration of uric acid in the blood as well as increased likelihood of its precipitation as MSU (monosodium urate or uric acid crystals. See, Gout Basics for background). That factor is the reduction of the concentration of oxygen in the blood, which occurs in an individual suffering from sleep apnea.
    Sleep apnea is the repeated cessation of breathing for many seconds at a time during sleep, when the muscles lining the airway relax enough to allow it to close, until the brain jolts them to reopen. The resulting reduction of oxygen in the blood causes the cells in the body to undergo a process of disintegration, which leads to their generation of excess uric acid. Once the uric acid is formed, the process is irreversible, even when breathing restarts. With each apneic period, more and more uric acid is fed into the blood, faster than the kidneys can dispose of it. Furthermore, the increased ratio of carbon dioxide to oxygen in the blood makes the blood more acidic, so that its ability to hold uric acid in solution is reduced and MSU is more likely to precipitate. These processes were described in medical journal literature about twenty years ago, and subsequent literature has confirmed that sleep apnea leads to excess uric acid in the blood and in the urine.
    Thus, sleep apnea hits gout attacks with a double whammy. It feeds more uric acid into the blood plus it reduces the ability of the blood to hold the uric acid in solution so that MSU precipitates. The result is a gout attack that develops while sleeping.
    This dysfunctional blood chemistry begins to resolve after the sleeper awakens, when the apneic periods cease and the kidneys have time to catch up in their removal of uric acid from the blood. Thus, a blood test of uric acid taken several hours after awakening will often measure as normal. The excess uric acid occurs as a flare that the belated blood test never detects.
    The factors for increased risk of developing gout - heredity, overweight, alcohol use, middle or elderly age, male gender, female gender past menopause - are all the same increased risk factors for developing sleep apnea. But those who do not fall into these categories can develop either condition. It's just less likely. I am not overweight, and I never was. Yet I developed both in middle age. Now I have neither.
    Where Are The Data?
    One would think that in the twenty-year period since these physiologic processes were described, gout researchers would have conducted studies to determine what percentage of gout sufferers also have sleep apnea, and in what percentage of those does resolving the sleep apnea cure their gout. It hasn't happened. One can only speculate as to why, and some speculated conclusions may have a very cynical view of gout experts. What has been reported recently is a long list of serious diseases that have been found to have a strong association with elevated uric acid, but with no recognition given that all these diseases have previously been shown to be consequences of sleep apnea.
    I realized the sleep apnea/gout connection over five years ago when resolving my sleep apnea resulted in the complete cessation of my gout attacks. And I know that I am not the only one who has observed that result. Based on my information, my primary care physician has been screening all his gout patients for sleep apnea. He has found that a large majority of them have sleep apnea, when neither he nor they would have otherwise suspected it.
    Why This Is So Important
    The results found by my literature search and by my primary care physician have convinced me the sleep apnea is a major cause of gout attacks. I have the view that all gout sufferers should assume they have sleep apnea as the underlying cause of gout until proven otherwise. That means that all gout sufferers should be screened for sleep apnea, not only to cure their gout, but more importantly to prevent the development of much more serious diseases.
    Resolving gout is important. Even more important is diagnosing and resolving sleep apnea. Gout is very painful, but by itself it is not life threatening. If left untreated, sleep apnea is known to have numerous consequences that are life threatening - heart attack, heart arrhythmias, heart failure, stroke, diabetes, depression, kidney disease, and many other maladies. It is no wonder that this list matches closely the list of associations with hyperuricemia presented in the Is Gout Dangerous? posting on this website, because hyperuricemia is a direct consequence of sleep apnea. A fourteen-year study in Australia of people with sleep apnea who refused treatment concluded that the life expectancy of these people was 18 years shorter that of the general population, a conclusion that stunned even the study's researchers.
    Unfortunately, palliating your gout by using NSAIDs or prescription drugs does nothing to overcome your sleep apnea. It just masks the warning until one or more of the dire consequences of sleep apnea smacks you. In my case it was a transient ischemic attack (ministroke), atrial fibrillation heart arrhythmia, and diabetes, all of which I have recovered from. I was lucky that my sleep apnea consequences turned out to be reversible, but I have to maintain a strict diet to prevent the return of my diabetes.
    There are about 80 times as many people with sleep apnea as there are with gout. Ironically, those of us with gout may be the fortunate ones because we have an early warning of our sleep apnea, but only if we and our doctors know about the connection.

    Update (August 1, 2009):
    A recent study performed in Australia of the medical records of over 16,000 patients diagnosed with obstructive sleep apnea found that gout was present in about 5% of them. Other sources estimate that the prevalence of gout in Australia is .27% of the population. That means that in Australia the likelihood of gout is 19 times higher in people with sleep apnea vs. the general population. Statistics for other first world countries are probably very similar.
