Assessment of nutritional, clinical, and immunologic status of HIV-infected, inner-city patients with multiple risk factors.

Abstract

OBJECTIVE:

To evaluate the nutritional, clinical, and immunologic factors associated with human immunodeficiency virus (HIV)-infected, inner-city patients with multiple risk factors.

DESIGN:

Prospective cross-sectional nutrition evaluation of patients with HIV infection.

SETTING:

Patients were interviewed at the outpatient clinic at Mt Sinai Medical Center, New York City, NY.

SUBJECTS:

Our subjects were men and women older than 18 years of age and at all stages of HIV infection (n = 56).

OUTCOME MEASURES:

Anthropometric measurements, history of weight changes (maintenance of preillness body weight or decrease from preillness weight status), 3-day food records, and clinical laboratory tests.

STATISTICAL ANALYSES:

Tests were used to compare patients who were at a stable weight with patients who had lost weight with regard to the anthropometric, dietary, and clinical variables. Spearman's rank correlation coefficient and chi 2 tests were applied to examine correlations between pairs and differences in proportions, respectively.

RESULTS:

Patients were classified into groups according to whether they were at a stable weight (n = 25) or had lost weight (n = 31). All anthropometric measurements, CD4 lymphocytes, and CD8 lymphocytes were significantly lower in the patients who had lost weight. No differences were observed between the groups for absolute lymphocyte count or transferrin, hemoglobin, and albumin levels. The mean energy intake of the 56 patients was 74% of the Recommended Dietary Allowance (RDA). Forty-seven patients (84%) took vitamin and/or mineral supplements within a range of 2% to 50,000% of the RDA. No significant positive correlations were observed between nutrient intake, CD4 cells, and absolute lymphocyte count.

CONCLUSIONS/APPLICATIONS:

All anthropometric measurements, CD4 lymphocytes, and CD8 lymphocytes were notably lower in patients with weight loss. The mean energy intake of the subjects was only 74% of the RDA. Megadoses of vitamin supplements were taken by a large number of patients, but no significant positive effects were observed for absolute lymphocyte count and CD4 cells. Although supplementation of micronutrients may influence the progression of HIV infection, a balanced, nutritious diet may be more beneficial in maintaining or improving the physiologic status of the patients. However, members of a high-risk population may benefit less from HIV-related social services and food or nutrition resources. With the growing number of injection-drug users in the acquired immunodeficiency syndrome population, it will be essential to develop comprehensive strategies to address the interconnected needs for medical and nutrition care. Ensuring that patients have adequate meals during an extended course of treatment in the outpatient clinic or that dietitians have meals available in group settings or through home-delivery service may be the most appropriate nutrition intervention in these high-risk patients.
