Aim: Supplementation with polymeric formula diet was evaluated as seco
nd step of a nutritional intervention program for malnourished, but ot
herwise clinically stable HIV-infected patients. Patients and Methods:
34 patients with weight loss, without opportunistic infections, diarr
hea or fever, not responding to nutritional counselling as first inter
vention, were included. They were given 1000 kcal per day as polymeric
formula. If further weight loss occurred, dose was increased to 1500
kcal per day. Nutritional status was determined by body weight and bio
electrical impedance. Results: After four weeks, 7/34 patients already
stopped intake. Only 10/34 patients completed three months of treatme
nt. The average intake during three months was 496 +/- 363 kcal/d. Rea
sons for drop-out were intervening clinical deterioration in eight, ea
rly improvement in six, but intolerance or loss to follow-up in ten pa
tients. On average, body weight did not change. Intake of formula diet
and weight changes were not correlated. Conclusion: Oral supplements
are a feasible, cost-effective and safe treatment of malnutrition, but
they are accepted only for short time and in limited amount. To estim
ate efficacy of this treatment, clinical reasons for malnutrition must
be considered. More effective nutritional treatments are needed for c
hronically malnourished HIV infected patients.
