Lecture 11a 24 MARCH 2014 Arthritis and Dermatitis
Osteoarthritis (OA)
-involves swelling of the joints
-overweight – causes wear of cartilaginous surfaces
-such wear results in loss of chondroitin
sulphate and glucosamine which are carbohydrate polymers
Rheumatoid arthritis (RA) -autoimmune attack that in part involves loss of chondroitin sulphate and glucosamine
Nutrition approaches to Arthritis
-appropriate nutrition and exercise may prevent weight gain thus avoiding that cause of osteoarthritis
Nutrition approaches to Arthritisnutraceuticals
-chondroitin sulphate
-glucosamine
-both of these nutraceuticals are meant to replace lost chondroitin sulphate and glucosamine
-both readily available over the
counter (OTC) and are useless
Nutrition approaches to ArthritisNutraceuticals
-fish oils reduce arachidonic derived pro-inflammatory eicosanoids while producing anti-inflammatory eicosanoids in RA but not OA -evening primrose oil, blackcurrant oil, and borage oil reduce arachidonic derived pro-inflammatory eicosanoids while producing anti-inflammatory eicosanoids in RA but not OA -review pathways involved for nutraceutical oils
Class activity-what is the best nutritional approach to arthritis? Why?
Dermatitis
Atopic (eczema)
-skin inflammation that is due to an immune response
-can be due to a food allergy
-solution -avoid food allergen
Dermatitis-nutraceutical
-fish oils reduce arachidonic derived pro-inflammatory eicosanoids while producing anti-inflammatory eicosanoids -evening primrose oil and borage oil reduce arachidonic derived pro-inflammatory eicosanoids while producing anti-inflammatory eicosanoids -as with RA many of these trials include subjects that are on anti-inflammatory prescribed drugs- what is the impact of this?
Dermatitis
Sebborheic (scaly)
-can be due to biotin deficiency
solution: avoid biotin deficiency
- can be due to riboflavin deficiency
solution: avoid riboflavin deficiency
Scaling eczema-like dermatitis
-can be due to linoleic or -linolenic acid deficiency
-this may be a problem with long term TPN
Nutritional remedy for dermatitis (types above) in general
-topical application of retinoids (similar in structure to vitamin A)
-reduces dermatitis
-avoid linoleic or -linolenic acid deficiency
Dermatitis herpetiformis -causes skin lesions pruritic-itching
vesicular-vesicles
papular-solid elevation of the skin - all of these lesions are consistent with
coeliac disease and are relieved by a gluten-free diet
Lecture 11b
24 MARCH 2014 Colitis, Migraine and Respiratory
Colitis
Inflammation of the colon
Diarrhea is an issue since the inflamed colon is incapable of its normal water management function- i.e. removing water from the faeces
Complete bowel rest helps
Ulcerative colitisTreatment Complete resection (removal) of colon
No nutritional implications but may be diarrhea initially
This diarrhea is transient and apparently self-correcting
Evening primrose oil may have some limited success for this type of colitis in terms ofstool consistency but this contradicts self-correcting diarrhea
Diversion colitis
Surgical diversion process by which the distal colon is left intact but without the stool stream
This results in abdominal cramping with mucoid or bloody diarrhea
Infusion of salt solution containing short chain fatty acids(scfa) (2-4 carbon fatty acids) into rectal remnant is a remedial measure but complete reanastomosis is the only complete cure
Migraine
Dural blood vessels become dilated and the pulsatile blood flow through these vessels distends and irritates the highly pain sensitive dura mater
-this would explain the throbbing nature of migraine headaches
-inflammatory component to migraine headache has been proposed
Nutritional management of migraineRiboflavin administration
Metabolites of riboflavin participate in overcoming the mitochondrial defect that that plays a role in migraine pathogenesis Avoiding foods-Certain foods in certain persons trigger migraines -however this is highly individual with one food or group of foods affecting a particular person but not another
Nutritional management of migraine
However dietary restriction of a food or food groups may upset the principles of adequacy, moderation, variety, nutrient density, energy control, and balance
Migraine
Foods contributing to migraine:
Citrus foodsTea(flavonoids)CoffeePorkChocolateMilkNutsVegetablesCola
Migraine
-food components affecting vascular tone and causing migraine (highly individual):
tyramine, phenylalanine, phenolic flavonoids, alcohol, food additives (sodium nitrate, monosodium glutamate), aspartame, caffeine
Migraine
-foods thought to trigger migraines subsequent to hypoglycemia are:
chocolate, cheese, citrus fruits, bananas, nuts, cured meats, dairy products cereals, beans, hot dogs, pizza, food additives coffee, tea, cola drinks, alcoholic drinks such as red wine, beer or whiskey distilled in copper stills
Migraine -solution to all this is trial and error elimination
of foods including meticulous record keeping
Respiratory Acute respiratory failure
Need sufficient energy and protein to support lung function and prevent infections without overtaxing the compromised respiratory system
Fluid and sodium restrictions may be necessary to ease pulmonary edema
Respiratory
Acute respiratory failure
Overfeeding causes increased carbon dioxide which results in additional respiratory requirement-therefore reduce kcal to an appropriate level(energy to support lung function and prevent infections without overtaxing the compromised respiratory system)
Respiratory
Aspiration pneumonia
Potentially lethal lung infection
Nasogastric feeding or gastrostomy or jejunostomy which allows the lower esophageal sphincter to remain closed
-all this helps to reduce aspiration risk
Respiratory
Chronic obstructive pulmonary disease (COPD)
Emphysema and chronic bronchitis are the two most common examples of chronic
obstructive diseases
COPD patients frequently experience:-weight loss, protein energy malnutrition (PEM) and infections due to anorexia
-poor food intake and high energy expenditure both due to laboured respirations
Respiratory Chronic obstructive pulmonary disease addressed by:
Weight loss (caloric restriction combined with appropriate exercise levels)
Malnourishment- gradual re-feeding as tolerated
-easy to eat foods in small meals to improve food tolerance- enteral feeding may help
-need fewer kcal from carbohydrate due to carbon dioxide issue
Avoid overfeeding –carbon dioxide load issue
Respiratory Cystic fibrosisLaboured breathing- increased kcal and protein and do not restrict fat
Enzyme replacements for pancreatic impairment
Multivitamin including fat soluble vitamins
Table salt to overcome electrolyte losses due to sweating
Additional fluids to liquefy thick secretions and prevent dehydration
Maintain appropriate height to weight ratio
Lecture 11c
24 MARCH 2014 Ulcers, Pruritis
Ulcers Generally refers to peptic ulcer-an erosion of top layer of cells from the lining of the esophagus stomach or small intestine Ulcers may also develop in the mouth, upper esophagus and large intestine
Ulcers and NutritionPatient should:
-relax during meals, eating slowly, chewing thoroughly,
-avoid overeating, alcohol, caffeine and caffeine containing beverages, decaffeinated tea and coffee, and except as tolerated pepper-containing and spicy foods Evening primrose has been proposed to help but this proposal is subject to problems such as small subject numbers and poorly controlled studies
Pruritis
-this is itch -can result from liver and kidney disease, cancers, parasites, aging and dry skin, and contact dermatitis
Pruritis and Nutrition -nutritionally address each of diseases generating the pruritis, address life cycle issues (aging and dry skin frequently go together) or address aging or dry skin separately as appropriate -contact dermatitis can be dealt with as per earlier mention of dermatitis -Evening primrose oil has had controversial success in this regard (i.e. pruritis)
