Transthyretin is a transport protein that binds with thyroxin and retinol-binding protein (12) buy 160 mg malegra dxt plus overnight delivery. It is another negative acute-phase reactant purchase 160 mg malegra dxt plus with visa, and decreases in response to stress and infection order malegra dxt plus 160 mg visa, but it is also altered by zinc status (12) buy generic malegra dxt plus 160 mg line. The advantages to using transthyretin are its short half-life, which is about 2 days (12,13), making it more sensitive to changes. However, it also has all of the disadvantages that have been described for serum albumin, including lack of specificity and high cost (12). Creatinine is found primarily in the muscles and is sometimes used as an indicator of muscle mass and adequate energy status. Serum creatinine is 22 Part I / Introduction to Rheumatic Diseases and Related Topics affected by disease and diet. A high consumption of muscle meats that contain creatine in the diet may give rise to high serum creatinine. A complete 24-hour urine collection is best, but collecting 24-hour urine samples may be difficult for ambulatory patients. The skeletal muscle mass (in kilograms) is sometimes very roughly estimated with this equation: the 24-hour urinary creatinine (grams per day) is multiplied by 18. Urinary creatinine levels are increased with exercise and with high meat intake (13). Urinary 3-methylhistidine is found only in muscle and is associated with muscle mass. A complete 24-hour urine 3-methylhistidine collection is required to obtain estimates of muscle mass. Calcium Serum calcium levels may be measured using total calcium or ionized calcium tests, but both are tightly controlled and change little in response to diet; hence, they are rarely used for nutritional status assessment. Calcium is primarily transported in the blood either freely or bound with albumin, and it is involved in muscle contraction and blood clotting (13). The regulation of calcium and phosphorus levels in the blood is influenced by vitamin D, calcitonin, and parathyroid hormone (15). Iron There are many types of nutrition-related alterations to red blood cell and hemoglobin synthesis, including iron-deficiency anemia, folate-related anemia, and vitamin B12- deficiency anemia. Other non-nutritional conditions may contribute to microcytic or macrocytic anemias and should be considered when evalu- ating the biomarkers. If anemia of chronic disease is present, increased ferritin levels are not representative of iron-deficient status. For example, individuals with arthritis who are truly iron-deficient may have elevated or normal serum ferritin levels. It is important to evaluate each biochemical test and disease state to determine if iron supplementation is warranted. Hyperglycemia Fasting blood glucose helps to identify abnormal glucose metabolism owing to diabetes or drugs. These tests are particularly important for those with obesity, a family history of heart disease, atherosclerosis, or diabetes. It is important to ensure that individuals fast for 12 hours before the blood draw. Markers of Inammation Many of the acute-phase proteins are used to assess the presence of inflammation. A common medication and nutri- tional interaction is between the anticoagulant, warfarin, and vitamin K, which compete with each other for the same binding site in the coagulation cascade (17). Clinical manifestations occur late and are nonspecific, and may also be related to other conditions or multiple nutrient deficiencies. These signs and symptoms may be caused by a disease, medication, or nutritional deficiency. Comorbidities The presence of other diseases often increases risk for malnutrition. Some diseases have symptoms that may appear similar to those resulting from nutritional deficiencies. Biotin and riboflavin deficiencies include scaly, red rashes on the face and around orifices, which should be not be confused with the facial rash often found on patients with systemic lupus erythematosus. But dietary assessment is difficult and must be done carefully to distinguish under- or malnutrition owing to diet alone (a primary deficiency) from that resulting from other causes (secondary deficiency) (20). Primary deficiency results from inadequate intake, which may be influenced by socioeconomic status and conditions such as alcohol abuse or eating disorders. Secondary nutrient deficiencies result from increased physiological needs, increased nutrient losses in feces and urine, and other causes. In planning interventions it may also be helpful to know about shopping and cooking habits and the frequency of meals consumed away from the home (5). Medications and dietary supplement intakes are important to consider when assessing dietary intake. Some medications provide nutrients, such as antacids containing relatively large amounts of calcium. There may be sources of amino acids, sugar, and vitamins and minerals in other medications as well. Dietary supplement intake of vitamins and minerals and other nutrients should also be included in assessing nutrient intakes. The use of other supplements, especially botanicals, may be helpful in assessing interactions with medications. The individual (or if a child is the patient, the parent or caretaker) is asked about intake over the last 24 hours. Probing is usually done to help the individual remember foods or beverages he or she may have forgotten. Memory aids and tools are used to promote an accurate estimation of portion sizes, including measuring cups and spoons, photographs of food in a known portion size, and food models. The individual should not be led to an assumed or socially acceptable answer; instead, open-ended questions should be asked. Computerized dietary assessment programs are now available for research purposes with a multiple-pass interview style that decreases underreporting (21). In the first pass, the individual recalls food and beverage intake for the designated time period. Finally, in the fourth and final pass, the interviewer questions the consumption of supplements and medications that contain nutrients. The disadvantages include the reliance on memory, thus making it inappropriate for individuals with a poor memory, and the fact that some foods may be forgotten or purposefully omitted (5,21). Because a computerized dietary assessment program is not used, it is also difficult to calculate nutrient intakes. Some simply present a list of common foods and ask the respondent to recall consumption of the food over the past year. This permits a rough estimate of nutrient intake, which may be useful in epidemiological studies in particular. Without adjustments for caloric intakes, intakes are usually grossly overestimated. There may also be biases with underreporting of socially unacceptable items or behaviors such as high-fat foods, alcohol, and so on. Food Records Food records are another method of collecting dietary intake for nutrient analysis. The individual records the brand names, cooking method, and ingredients of mixed dishes in household measurements (21). Forgetting to record intake and inaccurate estimation of volume and weights of foods and beverages are disadvantages to this method (5,21). Environmental assessment includes the identification of physical and social influences on intake. Influences in the Physical Environment on Intake Conditions within the household, access to food shopping and cooking facilities, and other factors may greatly influence intake. For those who have difficulties ambulating, the use of assistive devices should be queried because they can make the process of food preparation much easier. It may also be useful to identify the number of people in the home (5), the person responsible for purchasing and cooking food, and whether there are facilities to store and cook foods properly during periods of illness when the person may be shut in the house (5,22). Other factors to determine include whether a car is available and how far it is to the grocery or convenience store, avail- ability of foods at nearby stores, and the patients ability to commute to and transport food from the store to the home (5). An environment that promotes physical activity also contributes to nutritional status. If necessary, efforts should be made to assist a patient with applications for food assistance programs (e. Family support and frequency of communication and activity with family and friends also need to be assessed because they too can influence dietary intake (18). In scleroderma, the mouth may become small, making it difficult for patients to feed themselves and consume adequate nutrients. Generic Quality-of-Life Indicators Evaluation of quality of life includes assessing physical ability and functional activity as well as the health-related emotional and social implications. Quality-of-life questionnaires are also available specifically for pediatric or adolescent patients. The most common measures include the Childhood Health Questionnaire, Pediatric Quality of Life Inventory Scales, and Quality of My Life Questionnaire (29). Arthritis-Specic Quality of Life Disease-specific quality-of-life questionnaires have been designed for many rheumatoid diseases. Table 1 lists the disease-specific quality-of-life measures for arthritis and related diseases. They are particularly useful because they provide specific information that is directly related to the disease. Indicators of malnutrition also include rheumatoid cachexia, which involves muscle wasting that is often replaced with fat (30). Even with good disease control and adequate caloric intake, skeletal muscle catabolism persists (31,32). Assessment of caloric and protein intake is important because inadequate intakes will further accelerate muscle loss. Muscle wasting also affects functional status and mobility, which may impair food shopping, meal preparation, and cleanup. As a result of the chronic inflammation, anemia of chronic disease is often present (10,11,34). Medication-related effects on biochemical indices of folic acid and iron status are also common. Some medications such as methotrexate also affect calcium and vitamin D status (1719). Dietary and functional assessments should include attention to energy intake and problems related to obtaining, preparing, and eating food. Patients with social support may have a better quality of life, potentially moderating the impact of pain, depression, and physical disability (33). The disease is chronic and characterized by an age of onset before 16 years of joint swelling, heat, and pain and stiffness of unknown origin (10, 11) that occurs for 6 weeks or more (11). Disease characteristics often include inflammation, fever, damage/deformity of joints, and altered bone growth (10). In abnormal bone growth, one bone may be longer than another at times of accelerated growth and later become stunted.
In this second scenario buy 160 mg malegra dxt plus, pathogens that are already present in the area do not necessarily need to be considered 160 mg malegra dxt plus free shipping, while those that are absent would require more attention effective 160 mg malegra dxt plus. In addition 160 mg malegra dxt plus, it is important to assess the presence of toxic substances in the environment (e. Since an assessment of the health risk of each identifed hazard is almost never feasible, it is necessary to select a small number of hazards that appear to have the greatest potential to pose important health risks. Risk must be then completely and rigorously estimated for each selected health hazard, i. The aim is to minimize them as far as possible, but one has to keep in mind that a certain risk will always remain. Yet, especially when dealing with an endangered species, adequate scientifc documentation of the project implementation including individual veterinary records is crucial. Every single individual, alive or dead, is a truly valuable source of information, for the present and for the future. Thus, even if disease risk assessment reveals that there are no diseases of concern in the frame of the translocation project, emphasis should still be placed on extensive sampling and information collection. On the one hand, all procedures, results from physical exams, complementary diagnostic tests and laboratory analysis need to be recorded in detail. Data on pathogens that are apparently not infuencing the health status of the animals should, as far as possible, also be collected in order to learn about the species and about the pathogens. On the other hand, biological samples should be stored for eventual retrospective studies. For example, an apparently emerging pathogen that was not considered at the time of translocation might be detected in the release area several years after translocation. If appropriate samples of the translocated animals have been stored, it will be possible to use them for a retrospective analysis in order to determine whether the translocated animals were already infected with this apparently new pathogen at the time of translocation. Decisions whether or not to proceed with wild animal translocations may be determined by the results of health risk analysis, but they also may be infuenced by a variety of other factors such as political and/or conservation issues. Health risk analysis informs decision makers regarding potential health risks and provides them with options to reduce risk if it is decided to proceed with the translocation (Leighton, 2002). For example, in case of a highly endangered species, it might be very diffcult to capture animals for translocation that are free of any pathogen that could represent a risk for another, widely distributed species in the destination environment. If this risk appears to be rather low, the conservation goals of animal translocation might be of higher priority than the avoidance of introducing pathogens into the destination environment. Furthermore, it is fundamental to differentiate between optimal and minimal or essential requirements. It is always interesting to perform testing for numerous infectious agents in all animals. However, it is necessary to establish clear criteria to decide which are the minimum standards to render an individual acceptable for translocation. The selected key agents should have frst priority, and the tests should be done as soon as possible. Overall, veterinary planning must take into account a number of points, which are summarized in Table 1. A comprehensive checklist for health risk analysis and protocol development is provided by the Offce International des Epizooties and the canadian cooperative Wildlife Health centre (Anonymous). Dental problems, such as fractured teeth with pulp exposure, are common problems in captive non-domestic cats and severe cases could be life-threatening due to a potentially secondary systemic disease (Roelke et al. Once in quarantine, newly arrived individuals might refuse to eat as a result of the stress caused by the changes in their environment (Roelke et al. Freshly killed, whole animals with the abdominal cavity opened can provide an effective feeding stimulus to some cats (Blomqvist et al. Although a minimal duration of 30 days is generally recommended for the quarantine of non domestic cats (Blomqvist et al. There are thorough overviews of common pathogens to be included in the health screening protocols of non domestic cats, and recommended vaccinations and anti-parasitic treatments (Blomqvist et al. Further general information on diseases of non-domestic felids is reported by Terio et al. Recommendations for the design of transport boxes for wild cats are presented in Blomqvist et al. A crated felid should be left in quiet, dimly lit surroundings and the attention of curious bystanders kept to a minimum (Blomqvist et al. Losses of single individuals in small populations can have a signifcant impact on future population characteristics. Furthermore, even if epidemics are considered improbable, they still can play an important role in the long-term viability of a population (Ballou, 1993). Valuable information can be gained from blood samples, faecal samples, and post-mortem material (Blomqvist et al. In order to learn from experiences and to allow for a long-term approach to conservation, documentation is essential (Breitenmoser et al. Hence, all recorded data should be maintained in a database and presented in written reports, ideally in form of internationally available publications. Information such as anaesthesia protocols that are considered safe and effcient, reference data for the species (e.

Rationale for surveillance and prevention of infectious and parasitic disease transmission among free-ranging and captive Florida panthers (Felis concolor coryi). A la hora de manejar este tipo de programas, se debe tener en cuenta que la supervivencia fnal de la poblacin que tratamos de conservar se ve ltimamente infuenciada por cmo la sociedad en general percibe y prioriza el problema de su conservacin y por cmo nos organizamos los profesionales de la conservacin para evitar la extincin de una especie. Resulta crucial tener una visin lo ms completa posible de este contexto social para gestionarlo efcientemente, evitando bloqueos interinstitucionales y confictos destructivos. Aunque el conficto tiende a ser visto como un proceso negativo, si se maneja adecuadamente, puede convertirse en una fuerza creativa de mejora constante de un programa. Para lograr esto, se propone: 1) incentivar el desarrollo de relaciones colaborativas frente a otras ms competitivas entre proyectos e instituciones; 2) incluir a profesionales en gestin de confictos dentro de los programas de conservacin, y 3) fomentar el amplio reparto de recursos no distributivos. Igualmente, se destaca la importancia que los aspectos organizativos pueden tener sobre la recuperacin de una especie amenazada. En este sentido, se propone: 1) desarrollar procesos de planifcacin colaborativa; 2) incentivar la creacin de equipos de trabajo efectivos adecuadamente liderados y con capacidad de trabajo sobre el terreno; 3) evitar que las estructuras de control institucional detengan el desempeo de acciones concretas y necesarias sobre el terreno, y 4) identifcar y minimizar procesos de desplazamiento de objetivos. Finalmente, se hace una llamada a la mltiple y frecuente evaluacin de los programas de recuperacin de especies amenazadas para asegurar su mejora constante y sistemtica. When managing a recovery programme, we need to be aware that the fnal survival of any population of concern will be ultimately determined by how society perceives and prioritises its conservation, and by how professional conservationists organize themselves to avoid its extinction. Any conservation programme of public relevance involves a complex arrangement of stakeholders with distinct identities, perspectives, demands and resources. It is key to achieve a clear picture of this social context in order to manage it effectively, and to avoid inter-institutional gridlocks and destructive confict. Even though confict tends to be perceived as a negative process, when properly managed it can become a creative force, encouraging programme improvement. To achieve this, I propose to: 1) include professionals with experience in confict management within conservation programmes; 2) promote the establishment of collaborative instead of competitive relationships between projects; and 3) encourage the open exchange of non-distributive values. In this regard, I propose to: 1) develop collaborative planning processes; 2) establish on the ground teams with effective leadership and strong capabilities; 3) avoid institutional arrangements focused on process control, which end up hindering actual implementation of necessary actions, and 4) identify and defuse goal displacement processes. There is a fnal call for multiple and regular evaluation of recovery programmes to promote constant and systematic improvement. This has been said in enough places and occasions to astonish any seasoned conservationist. What is most surprising is the wide gap that still remains between accepting the previous proposition and really bringing it into our daily practice. We repeat this and similar phrases, nodding sympathetically when someone proclaims these kind of statements in each 503503 congress or professional meeting and, afterwards, it seems like we almost forget about it. It sounds like a concept that it is always nice to say, but we M dont really need to turn it into actual actions. One might even fnd a certain contradiction in the title of this book, which calls for an interdisciplinary approach to ex situ conservation and then invests most of its space discussing biological aspects focused on husbandry, genetic management, veterinary aspects and reproductive physiology. Does the width and detail of subjects included in the book adequately represent the challenges that will determine the fnal success or any recovery programme? I believe that the answer to this question does not lie in a deliberate effort to ignore pressing and uncomfortable non biological issues, but in our professional training. Through several years of reading books, attending meetings and workshops, we have been taught in a very indirect subtle way, never explicitly that conservation is mostly a biological challenge. When a certain group of subjects are repeatedly taught, discussed and written, they become the only subjects that exist. Such process is best described through what the economist and political scientist Herbet Simon (1983) called bounded rationality: the ability of the human mind to perceive and comprehend our environment through certain flters and approaches that allow us to selectively reject and ignore facts and views that are alien to our personality and education. Thus, it looks like we, conservationists, refuse to explicitly and systematically incorporate most social issues in our professional algorithms. This rejection is carried on even if we hear and read about the importance of such issues or while we might be actually dealing with them most of our time. I think of my present professional situation: I must coordinate two ex situ conservation programmes for locally endangered mammals in Argentina: one for the giant anteater and the other for the pampas deer. Very seldom do I carry out some deer census on the feld or supervise the capture, handling and transport of anteaters; these being the few clearly biological moments of my work. It is clear to me that my biological-scientifc training has been and still is extremely useful to guide my decisions and to help me convince other stakeholders. But it is also true that most of the time I see myself navigating through and trying to manage problems that are essentially non biological and will eventually determine if we achieve our conservation goals. And I do not see myself as an exception among professionals managing ex situ conservation programmes. As an example, the captive Breeding Programme for the Iberian lynx was blocked for years by interpersonal and interinstitutional confict. As a result of such confict, a measurable biological result was obtained: no Iberian lynx were born in captivity. Only when this history of destructive confict was properly managed through the establishment of a consensus policy and a widely respected captive breeding team, we started witnessing the history of biological success so well described in this book. The lesson is simple: social and political problems can be behind the fnal failure or, at least, signifcant delay of many recovery programmes. Hence, my purpose with this chapter is to join my voice to many others (clark et al. To do so, Ill present some themes and recommendations that might guide professionals involved in these programmes. Whenever possible, and in order to ft the chapter within the spirit of this book, I will use examples from the Iberian lynx conservation process, of which I have been an external but passionate witness for more than 10 years. To specialists with a background in natural sciences who are involved in ex situ/in situ conservation programmes: be aware of your conceptual and academic biases your bounded rationality and be sensitive to the need for calling social scientists and professionals to bring their knowledge and expertise into the conservation challenge. To conservation professionals involved in actual management of ex situ and in situ populations: open your mind to a wide transdisciplinary understanding of the challenge at hand and try to set up interdisciplinary teams that can comprehend and handle it in its myriad of biological and social aspects.

Treatment plans for rheumatic diseases vary depending on the type of disease and the patients condition safe 160mg malegra dxt plus. Medications for the treatment of rheumatic diseases are often used to relieve symptoms and prevent further worsening of the disease rather than to cure the disease. Lyme disease, infectious arthritis, and gout are some of the exceptions in which case symptoms of arthritis can be prevented or cured with early intervention and proper medications. Drugnutrient interactions can change both the therapeutic efficacy of medications and the nutritional requirements of patients. Therefore, understanding potential drug and food or nutrient interactions is crucial for maximizing biological effectiveness and minimizing the side effects of medications while ensuring optimal nutritional status of patients. Anticytokine-based therapies have emerged recently and are often used in combi- nation with conventional therapies. Potential drugnutrient interactions are reviewed in relation to these different categories of therapies. Alteration of Pharmacokinetics by Food Foods may interfere with or alter the absorption or metabolism of drugs and cause a change in pharmacokinetics (1). Physicochemical interactions between nutrients and drug components include adsorption, complex formation, precipitation, and change in stability. Physicochemical interaction requires the simultaneous presence of the drug and the food component at the site of interaction. Therefore, timing of medication use in relation to food intake can influence the absorption of the drug. Drugs absorbed only in the upper intestine have a greater potential for reduced absorption when given with food (2). Certain rheumatic disease medications such as methotrexate and penicillamine should be taken in a fasting state to prevent a decrease in absorption (1). Modulation of Biological Mediators of Rheumatic Diseases by Nutrients Nutrients can modulate the course of therapy by their effects on biological mediators of rheumatic diseases such as cytokines and prostaglandins. Nutrients may have their own effect on the symptoms associated with rheumatic diseases, and as such, may influence the dose requirements of drugs. Nutrients may also affect side effects of the drugs to make the medication more or less tolerable. Omega-3 (n-3) fatty acids have been shown to have a significant impact on the production of eicosanoids and proinflammatory cytokines, which play a crucial role in the pathology of rheumatic diseases (3). Change in Nutritional Status by Drugs Drugs can often change the nutrient status of the patient. Drugs can also cause low levels of certain nutrients by interfering with nutrient absorption. Therefore, dietary intake and the nutritional status of patients should be monitored during the course of therapy to ensure adequate intake of nutrients and to prevent nutritional imbalance associated with drug therapy. A lower peak plasma concentration and a delayed absorption of ibuprofen were observed when the drug was administered in a fed state (30 minutes after continental breakfast consumption) compared with a fasting state. When administered with food, the maximum plasma concentration and the area under the plasma level curve of the metabolite of nabumetone increased (10). Although the time to reach maximal plasma concentration was delayed by 1 hour when adminis- tered with a high-fat food, the observed peak plasma concentration was increased by concomitant food intake. Therefore, in patients with arthritis, celecoxib can be given either with or without food. For acute therapy, it may be preferable that celecoxib is given in the fasting state to avoid the food-induced lag time in its absorption (7). Supplementation of n-3 fatty acids results in increased production of prostaglandins and thromboxanes in three series and leukotrienes in five series. Clinical Benefits of n-3 Fatty Acids in Rheumatoid Arthritis Dietary n-3 fatty acids are one of the most extensively studied dietary therapies in relation to rheumatic diseases. They reported that there was no effect of n-3 fatty acids on patient reports of pain, swollen joint count, damage, and patients global assessment. However, in a qualitative analysis of seven studies that assessed the effect of n-3 fatty acids on anti-inflammatory drug or corticosteroid requirements, six demonstrated a reduced requirement for these drugs. At 3 years, 18 patients who consumed either bottled fish-oil juice or fish-oil capsules (71gcapsules twice daily) to provide 4 to 4. In animal models, feeding fish oil was shown to impair host resistance against Listeria monocytogenes (18) and to delay virus clearance in mice infected with influenza virus (19). Greater weight loss and suppression of appetite were observed following influenza infection in mice fed the fish oil diet for 14 days. However, the high level of vitamin E used (300 M) in combination with aspirin in this study makes it hard to extend these findings to clinical practice. In a 62 Part I / Introduction to Rheumatic Diseases and Related Topics double-blind, placebo-controlled, randomized study, Edmonds et al. Vitamin E did not have any effect on joint inflammation assessed by the Ritchie articular index, the duration of morning stiffness, or the number of swollen joints. Vitamin E significantly decreased pain parameters, suggesting some analgesic effects. They also increase the expression of adhesion molecules on the endothelium contributing to the emigration of inflammatory cells and lymphocytes from the systemic circulation (26). These factors contribute to the destruction of cartilage and bone, and the worsening of inflammation. Infliximab is a chimeric monoclonal antibody with mouse Fv1 and human immunoglobulin (Ig)G1, whereas adalimumab is a recombinant human IgG1 monoclonal antibody. Modulation of Proinflammatory Cytokines by n-3 Fatty Acid Supplementation Fish-oil supplementation can modulate inflammation by decreasing the production of proinflammatory cytokines. When nine young healthy subjects consumed 18 g of fish- oil concentrate per day (to provide 2. Twenty weeks after the end of supplementation, the production of both cytokines returned to baseline levels. Even a more modest level of n-3 fatty acid consumption from dietary sources, rather than from a supplement, had a significant impact on the production of proinflammatory cytokines. There is no study available yet in which the interaction between n-3 fatty acids and the efficacy of treatment with infliximab or adalimumab has been investigated. The maximum serum methotrexate concentration was significantly lower after oral administration in the fed state (0. The bioavailability of methotrexate decreased approx 20% when it was administered in the fed state. Folate Status and Supplementation in Methtotrexate Treatment Methotrexante is a known folate antagonist that inhibits dihydrofolate reducatase. It may also influence several other steps in folate metabolism and cause cellular depletion of folate and increased homocysteine levels. A persistent increase in plasma homocysteine concentrations was also observed in patients treated with methotrexate (4,34,35). Toxic effects associated with methotrexate therapy have been reported in 30 to 90% of patients; adverse effects are the main reason for discon- tinuing therapy. A low dose of folate supple- mentation has been reported to reduce the side effects of methotrexate therapy. Folic acid at either dose did not affect the efficacy as judged by joint indices and patient and physician assessment of disease. Folic acid-supplemented groups had significantly lower toxicity scores (duration of toxic events intensity clinical severity factor per 4 weeks in the protocol). Among 28 patients in the placebo group, dietary folate was negatively correlated with toxicity score. Negligible toxic effects were observed when dietary folate intake exceeded 400 g per day. Interaction of Glutamine With Methotrexate Glutamine is another nutrient that has been reported to have a significant inter- action with methotrexate (3840). Animals on a 3% glutamine-supplemented diet for 35 days had a 25% lower mean methotrexate total serum clearance and 65% lower renal methotrexate elimination compared with animals on a control diet (3% glycine diet). An increased methotrexate concentration with glutamine supplementation may increase the risk for methotrexate toxicity if the methotrexate dose is not adjusted. Rheumatic diseases are chronic inflammatory conditions that put patients at higher risk of oxidative stress; therefore, antioxidant nutrient requirements may increase. Methotrexate treatment decreases folate levels and corticosteroid treatment can cause low calcium and zinc status. Symptoms of rheumatic diseases such as pain and joint problems may lower appetites or limit patients from getting access to a variety of fresh ingredients. Concomitant consumption of food with medication can greatly influence absorption and efficacy of drugs. Specific instruction for the timing of medication is important for timely action and maximal absorption of drugs. Folate deficiency is frequently observed in patients with rheumatic disease, especially those treated with methotrexate. Lower folate status can adversely impact toxic effects of methotrexate therapy, resulting in discontinuation of the therapy. Patients should be encouraged to consume a balanced diet to at least meet the recom- mended dietary allowance for folate (400 g per day for adults) to minimize side effects of methotrexate. When it is hard to achieve proper levels of folate from the diet, folate supplementation, at an individually adjusted level, should be considered to provide some protection from toxicity of methotrexate therapy. However, levels or ranges of n-3 fatty acids that provide consistent clinical effects are not well defined.
