Slide 2

ObjectivesObjectives

• Define nutrition complications related to HIV and AIDS

• Identify ways to manage nutrition complications


Slide 3

Malnutrition DefinedMalnutrition Defined

• Malnutrition is when:• A person does not eat enough food• A person eats too much of one food group

and not enough of other food groups containing protein, vitamins and minerals

• Malnutrition decreases quality of life and ability to work

• Serious problem for people with HIV and AIDS

Vicious Cycle of Malnutrition and HIVVicious Cycle of Malnutrition and HIV

Poor Nutrition resulting in weight loss,

muscle wasting, weakness, nutrient deficiencies

Increased Nutritional

needsReduced food intake and increased loss of

nutrientsIncreased

vulnerability to infections

e.g. Enteric infections, flu, TB hence Increased HIV

replication, Hastened disease progression Increased

morbidity

Impaired immune system

Poor ability to fight HIV and other infections, Increased oxidative

stress

HIV


Slide 5

Weight Loss and HIVWeight Loss and HIV

• >10% weight loss shown to decrease survival in HIV-positive patients (Wheeler 1998; Tang 2002)

• Weight loss associated with onset of opportunistic infections (Wheeler 1998)


Slide 6

Micronutrients (MN) and HIVMicronutrients (MN) and HIV

• Since beginning of HIV epidemic, MN deficiencies found in HIV+ individuals• Selenium, B12, C lower in HIV+ compared to HIV- healthy

controls • Vitamin A levels lowest in pregnant women in developing

countries, but also in injection drug users• Iron deficiency and overload have deleterious effects on immune

system

• Serum MN levels vary depending on stage of disease and acute phase response therefore difficult to research

• MN supplementation shown in many studies to have effect on morbidity and mortality in adults and children on HAART or not


Slide 7

Causes of MalnutritionCauses of Malnutrition

• Unhealthy eating habits (not choosing nutritious foods and drinks), alcohol or cigarette use

• HIV infection and co-infections• Side effects of medications (weight loss,

diarrhoea, etc)• Food insecurity, poverty• Pregnancy• Metabolic and endocrine changes


Slide 8

Specific Complications with HIV/AIDSSpecific Complications with HIV/AIDS

• Wasting syndrome• Loss of appetite• Nausea and/or

vomiting• Fevers• Diarrhoea or

malabsorption• Tuberculosis

• Sores of the mouth or throat

• Changes in taste • Metabolic or

endocrine changes• Micronutrient

deficiencies


Slide 9

Loss of WeightLoss of Weight

Extremely dangerous due to: • Loss of immune function• Increased risk of infection • Shortened survival

Key interventions:• Prevention of weight

loss and malnutrition

• Identify and treat weight loss early

• Nutrition management

• Weight, height and body mass index (BMI)


Slide 10

Loss of Weight: Loss of Weight: Nutrition ManagementNutrition Management

• Address other symptoms or infections• Evaluate causes, check for parasites• Increase energy intake from food (add

high-energy meals/snacks)• Address food availability issues• Obtain height and weight at each visit • When available, add multivitamin

supplements and/or high calorie protein drinks


Slide 11

Wasting SyndromeWasting Syndrome

• Loss of greater than 10% of body weight, unintentionally, with persistent or chronic diarrhoea or unexplained, persistent fevers for greater than 1 month

• Loss of >10% body weight (measured and unintentional) over preceding 12 months OR loss of 5% body weight in 6 months sustained for 1 year


Slide 12

Nausea and/or VomitingNausea and/or Vomiting

• Nausea: a stomach distress with distaste for food and an urge to vomit

• Caused by medications, HIV, and other infections

• Leads to poor food intake and weight loss• Management:

• Small meals, frequently• Dry foods• Avoid lying down after meal• Drink liquids between or after meal• Assure adherence to medications and, if possible,

take medications with food


Slide 13

FeverFever

• A rise of body temperature above the normal (36.7 degrees Celsius)

• High body temperature leads to high energy use and weight loss

• Need increased energy intake from food

• Need increased fluid intake


Slide 14

Persistent DiarrhoeaPersistent Diarrhoea

• Diarrhoea: 3 or more loose or watery stools in a 24 hour period

• Persistent diarrhoea: diarrhoea that lasts for 2 weeks or more

• Caused by malabsorption, HIV, other infections, and/or medications

• Leads to weight loss, dehydration, malnutrition• Chronic diarrhoea can lead to malabsorption of

medications, leading to suboptimal levels of ART


Slide 15

Nutrition Management of Nutrition Management of Persistent DiarrhoeaPersistent Diarrhoea

• Treat dehydration (ORS, home solution)• Easy-to-digest foods (porridge, rice, bread,

bananas, cooked apples, yoghurt/omaere)• Small meals, frequently• Avoid rough foods like some raw greens or

cabbage; instead cook these until soft and easier to digest

• Avoid fatty foods (with fat malabsorption)• Avoid high sugar foods


Slide 16

Loss of Appetite or AnorexiaLoss of Appetite or Anorexia

• Caused by medications or illness

• Management:• Small, high energy meals, frequently• Eat most when feeling hungry• Add locally available herbs or spices to meals• Exercise


Slide 17

Changes in TasteChanges in Taste

• The loss or change in taste sensation causing less desire to eat food• Mouth often tastes metallic

• Caused by medications or mouth sores• Management

• Maintain oral hygiene • Treat sores• Add herbs/seasonings to foods• If meat is not appealing, encourage other protein

foods like chicken, eggs, fish, beans or milk


Slide 18

Thrush or Sores in the MouthThrush or Sores in the Mouth

• A fungal infection causing painful sores in mouth and throat affecting food intake

• Caused by medications or infections (more persistent with low CD4 level)

• Management:• Maintain oral hygiene: rinse mouth with warm water

plus salt or bicarbonate of soda• Choose soft, mashed foods• Drink liquids with straw• Avoid high acid foods (ex: oranges, tomatoes) • Avoid sugary foods (sugar promotes yeast growth)• Assure adherence to medications


Slide 19

Iron Deficiency and AnaemiaIron Deficiency and Anaemia

• Anaemia has multiple causes• Chronic illness, low serum Fe

• Nutrient deficiency (Fe, folate, B12)

• Hookworm, malaria, malignancy, OI, and AZT use


Slide 20

Iron Deficiency and Anaemia (2)Iron Deficiency and Anaemia (2)

• Iron supplements, especially if anaemia is not iron deficiency related, may be more harmful

• Recommend: multivitamin/mineral (MVM) supplement and encourage iron-rich foods


Slide 21

Vitamin A Deficiency Vitamin A Deficiency and Supplementationand Supplementation

• Vitamin A Deficiency• Most significant in children and post-partum women

• Indications for supplementation:• Preventative vitamin A supplement immediately after

birth to all women and to all children 0-5 years old• Treatment doses for diarrhoea, measles, pneumonia

in children• Unclear if beneficial in addition to MVM for PLWHA;

best taken in MVM


Slide 22

Zinc and SeleniumZinc and Selenium

• Zinc and Selenium• Some research indicates zinc deficiency in

PLWHA on HAART• Selenium supplementation shown to improve

HAART response• Ensure adequate levels in MVM supplement• Zinc supplements (20mg) beneficial in

diarrhoea treatment (but not yet available in state sector in Namibia)


Slide 23

Calcium and Bone ProblemsCalcium and Bone Problems

• HIV and HAART shown to promote bone loss, still under research

• Could lead to early osteoporosis• Encourage calcium and vitamin D-rich foods:

• Milk, cheese, yoghurt• Spinach• Dried fish• Beans, lentils, peas

• Prescribe multivitamin/mineral supplement• Avoid alcohol and excessive caffeine use


Slide 24

Specific Nutrient Considerations Specific Nutrient Considerations with TBwith TB

• Increased calorie intake (10-30% more) • Increase foods rich in protein, vitamins and

minerals to rebuild and heal lung tissues• Increase vitamin B6-rich foods if having skin

irritations or numbness• Beans, brown bread, bananas, potatoes, oilseeds,

unsifted maize, green leafy vegetables

• Increase fermented foods and drinks to increase “good” bacteria, often destroyed by TB medications


Slide 25

Nutrition During IllnessNutrition During Illness

• All people need food at all times – if they are sick or not

• For terminally ill clients, provide extra comfort and hydration

• Assist patients in hospital with eating

• For out-patients, ask about home based care or other support in the home or community


Slide 26

““Nutrition Management”Nutrition Management”

• What does this mean?• “Management” involves counselling,

education and giving nutrition advice• Food is not a cure for HIV, but it can help a

person feel better and live longer• Integrate with other health interventions like

medications, immunisations, etc.


Slide 27

Nutrition CounsellingNutrition Counselling

• Listen to the client

• Each client is different

• Allow client to make decision, but provide guidance

• Consider household/food situation

• Refer for community assistance

• Follow-up
