Home parenteral nutrition and AIDS

The evolution of AIDS in 25 patients enrolled in a home parenteral nutrition(HPN) programme was analysed retrospectively. All patients were grade 4C or 4D (CDC criteria). All suffered from major gastrointestinal symptoms, 13 had anorexia (< 700 kcal/day) and the overall mean weight loss was 21%. HPN involved administration of an all-in-one nutritional formula (caloric intake = 148% of MREE) which was infused at night through a Broviac type silastic catheter or a subcutaneous infusion port. It was continued until the patient's death or temporary recovery. 19 patients died during PN, 4 showed a temporary stabilisation. The average duration of PN was 180 days (54-358). Because of rehospitalizations for opportunistic infections or PN complications, the mean time spent at home was only 101 days (13-296), or 58.5% of the total duration of PN. 21 patients experienced weight gain and the Karnofsky activity index increased in half the patients. A temporary return to work was possible in only 3 patients. 15 PN related septicaemias were diagnosed for 4400 days of PN (0.34 for 100 days). On the whole, HPN seems to have been beneficial in 13 out of 25 patients, but the criteria for identifying patients who are likely to respond are not clearly established.
