To evaluate the nutritional, clinical, and immunologic factors associated with human immunodeficiency virus (HIV)-infected, inner-city patients with multiple risk factors.
Prospective cross-sectional nutrition evaluation of patients with HIV infection.
Patients were interviewed at the outpatient clinic at Mt Sinai Medical Center, New York City, NY.
Our subjects were men and women older than 18 years of age and at all stages of HIV infection (n = 56).
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.
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.
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.
评估与感染人类免疫缺陷病毒(HIV)且有多种危险因素的市中心患者相关的营养、临床和免疫因素。
对HIV感染患者进行前瞻性横断面营养评估。
在纽约市西奈山医学中心门诊对患者进行访谈。
我们的研究对象为年龄超过18岁且处于HIV感染各阶段的男性和女性(n = 56)。
人体测量、体重变化史(维持病前体重或病前体重下降情况)、3天食物记录以及临床实验室检查。
采用检验比较体重稳定的患者与体重减轻的患者在人体测量、饮食和临床变量方面的差异。分别应用Spearman等级相关系数和卡方检验来检验配对之间的相关性和比例差异。
根据体重是否稳定将患者分为两组(体重稳定组,n = 25;体重减轻组,n = 31)。体重减轻的患者所有人体测量指标、CD4淋巴细胞和CD8淋巴细胞均显著降低。两组在绝对淋巴细胞计数、转铁蛋白、血红蛋白和白蛋白水平方面未观察到差异。56例患者的平均能量摄入量为推荐膳食摄入量(RDA)的74%。47例患者(84%)服用了维生素和/或矿物质补充剂,剂量在RDA的2%至50000%之间。在营养素摄入量、CD4细胞和绝对淋巴细胞计数之间未观察到显著的正相关。
结论/应用:体重减轻的患者所有人体测量指标、CD4淋巴细胞和CD8淋巴细胞均明显降低。研究对象的平均能量摄入量仅为RDA的74%。大量患者服用了大剂量维生素补充剂,但在绝对淋巴细胞计数和CD4细胞方面未观察到显著的积极效果。虽然补充微量营养素可能会影响HIV感染的进展,但均衡、营养的饮食可能对维持或改善患者的生理状态更有益。然而,高危人群成员可能从HIV相关社会服务以及食物或营养资源中获益较少。随着获得性免疫缺陷综合征人群中注射吸毒者数量的增加,制定综合策略以满足医疗和营养护理的相互关联需求至关重要。确保患者在门诊长期治疗期间有足够的膳食,或者让营养师在集体环境中提供膳食或通过送货上门服务提供膳食,可能是对这些高危患者最合适的营养干预措施。
