Implicaciones bioéticas en el tratamiento integral al paciente afectado por enfermedades reumáticas / Bioethical implications in the integral treatment given to patients suffering from rheumatic diseases

La Ética es la parte de la filosofía práctica que se ocupa del hecho moral y de los problemas filosóficos que nacen de la conducta humana, la bioética resulta la rama de la ética que se dedica a proveer los principios para la correcta conducta humana; respecto a la vida. En el proceso de atención a los pacientes con enfermedades reumáticas se emplean variados procedimientos. Las nuevas tecnologías han mejorado notablemente su tratamiento integral; estos adelantos científicos deben ser empleados con la intención fundamental de no producir daño y previo consentimiento informado; por lo que resulta necesario argumentar acerca de las implicaciones bioéticas que resultan del empleo de los avances científico-tecnológicos en el tratamiento a los pacientes con enfermedades reumáticas(AU)

Ethics is the part of Practical Philosophy that deals with moral facts and philosophical problems that have their roots in human behavior. Bioethics is the branch of Ethics devoted to providing the principles for correct human behavior, with respect to life. Various procedures are used when treating patients with rheumatic diseases. New technologies have considerably improved their integral treatment; these scientific advances must be used with the main purpose of causing no harm and with prior informed consent. Therefore, it is necessary to argue on the bioethical implications that turn out from the use of scientific-technological advances in the treatment of patients with rheumatic diseases(AU)

Vitamin D supplementation and disease activity in patients with immune-mediated rheumatic diseases: A systematic review and meta-analysis.

BACKGROUND: Vitamin D serum levels and the presence and activity of rheumatic conditions have been associated. However, many studies are merely observational, and the existent randomized clinical trials were never systematically analyzed. Therefore, this study aims to provide a systematic review and meta-analysis of such a topic. METHODS: MEDLINE, EMBASE, LILACS, COCHRANE, and CINAHL were explored to identify randomized trials that investigated clinical repercussions of vitamin D (or analogs) supplementation for at least 3 months in rheumatic diseases. Standardized clinical and/or laboratorial outcomes related to disease activity were analyzed according to each disease before and after supplementation. RESULTS: Database searches rendered 668 results; 9 were included-5 on rheumatoid arthritis, 3 on systemic lupus erythematosus, and 1 on systemic sclerosis. Seven of the studies were meta-analyzed. After vitamin D supplementation, rheumatoid arthritis recurrence decreased; however, not significantly (risk difference = -0.10, 95% CI = -0.21, 0.00, P = .05). No statistical significance was observed regarding visual analog scale (mean difference = 2.79, 95% CI = -1.87, 7.44, P = .24) and disease activity score28 (mean difference = -0.31, 95% CI = -0.86, 0.25, P = .28). Regarding systemic lupus erythematosus, anti-dsDNA positivity was significantly reduced (risk difference = -0.10, 95% CI = -0.18, -0.03; P = .005). CONCLUSION: Vitamin D supplementation reduced anti-dsDNA positivity on systemic lupus erythematosus and could possibly reduce rheumatoid arthritis recurrence, although novel randomized clinical trials are needed to confirm and extend the benefits of this hormone in immune-mediated rheumatic diseases.

Caquexia reumatológica y otras alteraciones nutricionales en las enfermedades reumatológicas / Rheumatoid cachexia and other nutritional alterations in rheumatologic diseases

Las prevalencia de las alteraciones nutricionales en pacientes con enfermedades reumatológicas varía entre un 4 y un 95%, dependiendo del método empleado para su detección. Inicialmente agrupadas bajo el término de caquexia reumatológica, en la actualidad es posible ampliar el concepto de desnutrición conforme los mecanismos fisiopatológicos que participan, sea desnutrición asociada a procesos inflamatorios crónicos (caquexia), desnutrición asociada a procesos inflamatorios agudos (desnutrición proteico-calórica) y desnutrición asociada a baja ingesta alimentaria. El espectro clínico de la desnutrición asociada a enfermedades reumatológicas varía desde el paciente con bajo peso hasta el paciente con sobrepeso u obesidad, con disminución en la cantidad de masa magra, repercusión funcional, en calidad de vida y pronóstico, como común denominador. Adicionalmente, el incremento asociado en masa grasa aumenta el riesgo para el desarrollo de enfermedad cardiovascular. El manejo integral de las enfermedades reumatológicas debe de incluir aspectos para la prevención, la identificación y el manejo oportunos de las alteraciones nutricionales (AU)

The prevalence of nutritional alterations in rheumatologic diseases ranges from 4 to 95%, depending on the detection method used. Formerly described as the single term rheumatoid cachexia, nutritional alterations can currently be grouped and subdivided based on the physiopathological mechanisms involved: chronic disease-related inflammatory conditions (cachexia), malnutrition associated to acute malnutrition inflammatory conditions (protein-caloric malnutrition) and starvation-related malnutrition. Clinical manifestations of malnutrition associated to rheumatic diseases vary from the patient with low weight or overweight and obesity; with lean body mass depletion as well as functional repercussions, and impact of quality of life as a common denominator. Additionally, the associated increase in body fat mass increases the risk for cardiovascular morbidity. A multidisciplinary approach towards rheumatic diseases should include aspects oriented towards prevention, early identification, diagnosis and correction of nutritional alterations (AU)

The enthesopathy of celiac patients: effects of gluten-free diet.

Celiac disease (CD) is a gluten-sensitive enthesopathy occurring in genetically predisposed individuals that is caused by a permanent intolerance to gluten. The major environmental factor associated with the risk of developing celiac-related complications is persistent exposure to dietary gluten. The aim of this study was to determine the prevalence of lower limb enthesopathy in CD patients at first diagnosis compared with CD patients on a gluten-free diet (GFD). Fifty-five untreated CD patients (group A) and 55 CD patients on a GFD from at least 1 year (group B), matched for age and sex, attending gastroenterology outpatient clinic of the University Federico II of Naples, were enrolled in this study. All patients underwent clinical and ultrasonography examination. Among group A, 27 (49.8 %) patients presented at least one entheseal alteration as compared with 15 patients (27.2 %) of group B (prevalence rate ratio 1.83, I.C. 95 % = 0.48-7.01; p < 0.001). The Glasgow ultrasound enthesitis scoring system (GUESS) was significantly higher in patients of group A than in patients of group B. In conclusion, our study shows that enthesopathy is more frequent in untreated CD subjects with positive anti-tissue transglutaminase antibodies title, as compared to those on GFD and absence of serum anti-tissue transglutaminase antibodies title.

Fasting therapy - an expert panel update of the 2002 consensus guidelines.

Fasting for medical purpose (fasting therapy) has a long tradition in Europe and is established as a defined therapeutic approach in specialized fasting hospitals or within clinical departments for integrative medicine. In 2002, the first guidelines for fasting therapy were published following an expert consensus conference; here we present a revised update elaborated by an expert panel. Historical aspects and definitions, indications, methods, forms, and accompanying procedures of fasting as well as safety and quality criteria of fasting interventions are described. Fasting has shown beneficial effects in various chronic diseases with highest level of evidence for rheumatic diseases. Preliminary clinical and observational data and recently revealed mechanisms of fasting and caloric restriction indicate beneficial effects of fasting also in other chronic conditions such as metabolic diseases, pain syndromes, hypertension, chronic inflammatory diseases, atopic diseases, and psychosomatic disorders. Fasting can also be applied for preventing diseases in healthy subjects. In order to guarantee successful use of fasting and to ensure adherence of all safety and quality standards it is mandatory that all interventions during fasting are guided/accompanied by physicians/therapists trained and certified in fasting therapy.

Vitamin D and autoimmune rheumatologic disorders.

Vitamin D levels depend on many variables, including sun exposure, age, ethnicity, body mass index, use of medications and supplements. A much higher oral vitamin D intake than the current guidelines is necessary to maintain adequate circulating 25(OH)D levels in the absence of UVB radiation of the skin. In addition to the traditional known metabolic activities, vitamin D has been shown to modulate the immune system, and its deficiency has been linked to the development of several autoimmune disorders including type 1 diabetes and multiple sclerosis. Experimental use of vitamin D has revealed a novel role in the immunopathogenesis of autoimmune diseases. Disorders such as systemic lupus erythematosus, rheumatoid arthritis, Behçet's, polymyositis/dermatomyositis and systemic scleroderma have all been associated to some extent to vitamin D deficiency. If vitamin D deficiency occurs at a higher rate in patients with autoimmune disorders, then appropriate supplementation may be indicated.

[Dietary therapy for inflammatory rheumatic diseases]. / Ernährungstherapie entzündlich-rheumatischer Erkrankungen.

Patients suffering from inflammatory rheumatic diseases should be offered an individual dietary counselling, adequate for the specific disease, and concomitant nutrient intolerances or sensitivities, and co-morbidities. Dietary counselling is an important support of pharmacotherapy and should be installed simultaneously with DMARD therapy. Patient suffering from inflammatory rheumatic diseases are enabled by dietary education to support pharmacotherapy, and even contribute to a better long-term outcome. Benefits of nutritional therapy arise not before three month on the diet and intensify within 12 months. Especially initial pharmacotherapy has to be continued. Within one year doses of NSAIDs and glucocorticoids can be lowered by one third on the average.

[Diet in rheumatic disease]. / Ernährung bei rheumatischen Erkrankungen.

The goals of dietary therapy in rheumatic diseases are alleviation of under- and malnutrition, inhibition of inflammation, prophylaxis of osteoporosis, as well as recognition and treatment of nutrient sensitivities or intolerances.Inflammation inhibition in these patients is improved by manipulating the omega-3/omega-6 fatty acids ratio in the diet. Reduction of dietary arachidonic acid is recommended. This polyunsaturated fatty acid is the main precursor of pro-inflammatory mediators which interact with chemokines und cytokines. Simultaneously, intake of anti-inflammatory omega-3 fatty acids is increased. Studies have shown that this dietary regimen results in an amelioration of symptoms in patients with inflammatory rheumatic diseases. Dietary therapy in rheumatic diseases is often complicated by concomitant diseases and physical handicaps necessitating interdisciplinary patient care, consisting of rheumatologists, nutritionists, physiotherapists and ergotherapists. Dietary therapy of rheumatic diseases is an adjuvant therapy that should be initiated after a patient is properly diagnosed.

[The mediterranean diet model in inflammatory rheumatic diseases]. / Il modello nutrizionale mediterraneo nelle malattie reumatiche infiammatorie.

The Mediterranean diet is based on a pattern of eating closely tied to the Mediterranean region, which includes Greece and southern Italy. Essentially, the traditional diet emphasizes foods from plant sources, limited meat consumption, small amounts of wine and olive oil as the main fat source. The beneficial effects of the Mediterranean diet has been proven not only to cardiovascular diseases but also for diabetes, obesity, arthritis and cancer. Its anti-inflammatory and protective properties are linked to the large presence of omega-3 polyunsaturated fatty acids, vitamins, but especially to the constituents of extra virgin olive oil: oleic acid, phenolic compounds olecanthal, a new recently discovered molecule, with natural anti-inflammatory properties. It has been shown that the Mediterranean diet can reduce disease activity, pain and stiffness in patients with inflammatory arthritis and may thus constitute a valuable support for patients suffering from these diseases.

[Role of omega-3 polyunsaturated fatty acids in diet of patients with rheumatic diseases]. / Ruolo degli acidi grassi omega-3 nella dieta dei pazienti affetti da patologie reumatiche infiammatorie.

The beneficial effects of omega-3 polyunsaturated fatty acids have been widely described in the literature in particular those on cardiovascular system. In the last decade there has been an increased interest in the role of these nutrients in the reduction of articular inflammation as well as in the improvement of clinical symptoms in subjects affected by rheumatic diseases, in particular rheumatoid arthritis (RA). Nutritional supplementation with omega-3 may represent an additional therapy to the traditional pharmacological treatment due to the anti-inflammatory properties which characterize this class of lipids: production of alternative eicosanoids, reduction of inflammatory cytokines, reduction of T-lymphocytes activation, reduction of catabolic enzymes activity. The encouraging results of dietetic therapy based on omega-3 in RA are leading researchers to test their effectiveness on patients with other rheumatic conditions such as systemic lupus erythematosus and ankylosing spondylitis. Nutritional therapy based on food rich in omega-3 or on supplementation with fish oil capsules, proved to be a valid support to he treatment of chronic inflammatory rheumatic diseases.

[Metabolic syndrome in inflammatory rheumatic diseases]. / La sindrome metabolica nelle malattie reumatiche infiammatorie.

Toward the end of the last century a better knowledge of cardiovascular (CV) risk factors and their associations led investigators to propose the existence of a unique pathophysiological condition called "metabolic" or "insulin resistance syndrome". Among all, insulin-resistance and compensatory hyperinsulinemia are considered its most important treatment targets. Different definitions have been provided by World Health Organization (WHO) and by The Third Report of The National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP III). In particular, abdominal obesity, hypertension, low HDL cholesterol and hyperglicemia are the most common items used for its definition. The presence of MetS is effective in predicting the future risk of diabetes and coronaropathies. The evidence of a higher CV risk rate among different rheumatic inflammatory diseases has recently been associated with high prevalence of MetS in some cases. Rheumatoid or psoriatic arthritis have the large series among arthritis, whereas systemic lupus erythematosus among connective tissue disorders. This review analyses all most important studies about the evidence of MetS in rheumatic patients and the main clinical and prognostic significance of this relation.

Oxidative stress and nutritional prevention in autoimmune rheumatic diseases.

The hypothesis that oxidative stress favours flogistic and immune processes inducing autoimmune rheumatic diseases (ARDs) and their complications is still under discussion. In this review we take into consideration both the aetiopathological role of the diet in such diseases and the possible efficacy of dietary supports as adjuvants for the usual specific therapies. Moreover, we shall examine the hypothetical pathophysiological role of oxidative stress on ARDs and their complications, the methods for its evaluation and the possibility of intervening on oxidative pathways by means of nutritional modulation. It is possible that in the future we will be able to control connective pathology by associating an immuno-modulating therapy ('re-educating') with natural products having an anti-oxidant activity to current immunosuppressive treatment (which has potentially toxic effects).

Diets, dietary supplements, and nutritional therapies in rheumatic diseases.

Rheumatoid arthritis and many other systemic rheumatic diseases remain illnesses of unknown cause for which current therapy is often inadequate. This leads patients to seek questionable remedies, prominent among which are dietary manipulations. Is there a role for dietary modifications in the routine therapy for patients with rheumatic diseases? This article discusses the relationships between diets, fasting, elemental nutrition, vitamins, minerals, and foods for rheumatic diseases. Known scientific-based evidence for the use, safety, and efficacy of diets and dietary-related practices subscribed by patients with rheumatic diseases are presented. Studies that link diet with arthritis offer the possibility of identifying new therapeutic approaches for selected patients and of developing new insights to disease pathogenesis. Dietary therapy for arthritis, however, is still being investigated.
