1984

• Male pt, 26 years, HIV since 1983• 185 cm, 54 kg, BMI 15,8 kg/m2, weight loss 30%• Usual weight (<6mo) 74 kg, BMI 21,7 kg/m2

• Referral: diarrhea (15xday / >3 ltr) candidasis in mouth and throat, night sweating, fever, depressed

• Intake: 1 liter yoghurt / day, 3 glasses of tomato juice, 2 liter ORS and some soup

• 18 kcal/kg/ 0,6 g protein/kg bw

Relevant?

Dietary treatment 1984• Nutritional problems:

– disturbed energy balance due to:– Anorexia (depression – treatable)– Swallowing problems (candidasis - treatable)– Diarrhea (untreatable) – Low immunity (untreatable)

• Nutritional intervention:– Restore energy balance if possible

• Future of the patient:– new opportunistic infection– High mortality

Relevant?

2004

• Male pt, 46 years, HIV since ’94• 185 cm, 102 kg, BMI 30, 15 cigarettes/day• Referral: obese, glucose (>15mmol/l) & TG

(>10 mmol/l)• Drugs: 3 dd 4mg Amaryl, 1x30mg Pioglitazon,

1x500mg Metformine 2dd150mg Epivir, 2dd 300mg Abacavir, 4x200mg Efavirenz

• Intake: high on sugar, SFA & alcohol• Activities: low due to depression and tiredness

Relevant?

Dietary treatment 2004

• Nutritional problems:– disturbed energy balance (high intake, low in activities

due to depression)– High TG due to HAART– High glucose due to HAART

• Nutritional intervention:– Low caloric diet (low sugar, high PUFA)

• Future of the patient– Cardiovascular problems due to HAART– lipodistrophy– low mortality

Relevant?

Nutritional goalsHealthy adults

• good nutritional status– good weight: balance

between intake & activities

– 100% DRI Micronutrients

– Good Fluid intake– Good Fiber intake

Prevention diseases!

HIV infected adults• Good nutritional status

– Protect LBM– REE ± increased– Micronutrient need

unknown– HAART influence

No cure!

Relevant?

Relevant?

HIV treatment1. Highly Active Anti Retroviral Therapy

(HAART)– Immunity low

2. Non HAART– Good immunity status, mild infection– End stage– Poor, no access to health care

Relevant?

Is nutritional status relevant to prognosis in HIV?

• HIV infection does not lead invariably to weight loss, but weight loss is a feature of seroconversion illness and opportunistic infections (Palenicek 1995)

• Body composition changes during HIV under HAART are different from starvation in non-HIV (Salomon 2002)

Lactic acidosis

• 0,8 – 1,3 / 1000 HIV pt / year• Drug/nutrient interaction: Stavudine 25pt/y• Mitochondrial dysfunction: increase of

production of lactate from pyruvate• Deplete vit B1 & B2• Liver disease• Treatment: vit B1 & B2 IV

Relevant?

Prevent weight loss in HIV HAART & non-HAART

1. Record weight at each clinic visit2. Control HIV infection and lower virus load3. Investigate and treat secondary infections4. Evaluate and treat nausea, vomiting, and diarrhea5. Examine the oral cavity regularly6. Evaluate for and treat hypogonadism7. Treat alcohol and drug abuse8. Address eating disorders and mental illness9. Provide services to improve access to food10. Stop cigarette use11. Maximize caloric intake (appetite stimulance??)12. Strength training of large muscle groups 13. Consider hormone therapy (anabolic)

100% RDA micronutrients

• Normal absorption: normal needs• Malabsorption: deficiencies• Very few controlled trials on

micronutrients and their optimal use

• Advice: multivitamin & trace element supplementation if nutritional problems are present (malabsorption, low intake)

The relevance of nutrition?Relevant to maintain body cell mass: need for optimum protein intake (1,5 g / kg BW)

Relevant to maintain energy balance: possible to treat immunity status with HAART

Relevant to influence on immunity by using 100% DRI vitamins & trace elements

Relevant to side effects & toxic amounts of:• Vit A, D, niacin, vit B6, vit C, Cu, Fe, Se, Zn etc.
