HAART
Slide 4
ARV vs. HAART
• ARV: antiretroviral medication refers to the
individual medications that are used to
inhibit the multiplication of retroviruses like
HIV
• HAART: highly active antiretroviral therapy
refers to the treatment regimens
recommended by leading HIV experts to
aggressively suppress viral replication and
progress of HIV disease

Modern (New) Therapies
• HAART: combination of 3 or more of the
following:
• Non-nucleoside reverse transcriptase inhibitors
(NNRTIs)
• Nucleoside reverse transcriptase inhibitors (NRTIs)
• Protease Inhibitors (PIs)
• Therapies to treat opportunistic infections
• Ex: TB treatment, antifungal, antibiotics
• Malaria treatment
• Multivitamin/mineral supplements

Slide 6
Traditional Therapies
• Herbal remedies, teas/infusion, or high-dose
vitamin supplements
• Caution: some may interact with other medicines
or foods
• Ex: Avoid garlic supplements with Saquinavir
• Some therapies may be expensive, replace
food, and can cause liver damage (especially if
combined with other medications)
• Always ask clients what traditional therapies they are
taking

How Can Diet Help with Medications?
• Management of side effects
• Enhance flavour of foods
• Balanced meals help prevent side effects
and promote adherence
• Avoid alcohol use with medications
• Address food security issues with client

Pregnant and Lactating Women
• More food needed during pregnancy and
lactation
• Good nutrition status increases
effectiveness of HAART/medications and
reduces infant low birth weight

Slide 10
Infants and Children on HAART
• Increased nutrition/energy needs
• Greater risk for malnutrition, morbidity
(illness) and mortality (death)
• Closely monitor growth (weight and
height), clinical signs of malnutrition (i.e.
wasting, oedema) and feeding patterns

Common Side Effects from Medicines
•
•
•
•
•
•
•
Nausea, vomiting, diarrhoea
Poor appetite
Changes in taste
Metabolic Changes
Iron Deficiency Anaemia
Liver toxicity
Rash/skin problems

Slide 12
Metabolic Changes
• Lipodystrophy: changes in the way the body
makes, uses and stores fat. Two types:
• Lipoatrophy: loss of subcutaneous fat (fat under the
skin), mostly in arms, legs, buttocks, and face
• Lipohypertrophy: fat accumulation, mostly around the
abdomen, chest, and behind the neck
• Biochemical changes: high blood fat levels, high
blood sugar levels
• Increases risk of heart disease and diabetes

Slide 13
Metabolic Changes
• Associated ARVs
• d4T (stavudine)
• Possibly other NRTIs
• Protease inhibitors and
boosted PIs
• Early prevention, detection,
and treatment are important!
• Look for physical signs of
lipodystrophy/lipoatrophy
• Biochemical monitoring

Dietary Considerations for
Metabolic Changes
• Reduce refined starches (e.g. maize, white
bread, pastas, sugar)
• Increase fibre from whole grains (e.g. oats,
mahangu, brown bread) and fresh fruits
and vegetables
• Eat more “good fats” from foods like oils,
avocado, and nuts and less “bad fats” from
butter and deep fried foods
• Exercise at least 45 minutes a day

Counselling Pre-HAART
•
•
•
•
•
•
What are client’s eating habits?
Number of meals per day?
What are common foods eaten?
Any times when food is not available?
Any recent weight loss? How much?
Any current medications (consider modern and
traditional medicines)?
• What are specific food-medication interactions or
common side effects of proposed ART regimen?

Slide 18
Counselling During HAART
• What is the client’s food-HAART schedule?
• What side effects does the client have?
• Has the client lost weight since beginning
HAART?
• Is the client taking other medications or
traditional therapies?
• If traditional therapies taken: in what form (pill),
what is cost, and do these replace meals?

Food and Medication Table Activity
•
Questions to answer:
1. Is the diet adequate for the medication
regimen this person is taking?
2. What should be changed, if anything?
3. What are some side effects with the
medications?
4. What can you tell the client to do to prevent
or manage potential side effects?

Slide 24
Key Points
1. All persons need to have access to healthy
food, especially those on HIV medications
2. Counsel clients on food effects of their
medications
3. Help clients make a food-medication timetable
4. HIV medications can help a person with HIV
live longer, but not without proper nutrition
