Investigators are now predicting that 75 to 80 per cent of the 1.5 to 2.0 million HIV-positive patients in the United States will develop AIDS. The majority of AIDS patients will experience progressive weight loss and malnutrition prior to their death. Because nutritional therapy has clearly been demonstrated to have a beneficial effect on the clinical course and immunologic status of the critically ill general population, one must not disregard the potential positive benefits of nutritional therapy in the treatment of malnourished ARC/AIDS patients. As a result of the escalating cost of ARC/AIDS medical therapy and the predicted AIDS epidemic, ARC/AIDS nutritional therapy regimens must be simple to administer and cost effective. At SFGH, we have developed specific nutritional screening criteria in an attempt to identify those patients who would most benefit from nutritional therapy. Prior to initiating therapy, we interview each patient, perform a complete physical examination, conduct a thorough nutritional assessment, evaluate their gut function, and calculate their daily caloric and protein requirements. The selection of appropriate oral, enteral, and parenteral diets is crucial in the successful management of these patients. Because all ARC/AIDS patients differ in their nutritional requirements, diet tolerance, and degree of intestinal dysfunction, there is no single nutritional therapy regimen that can be utilized in the treatment of all these patients. Therefore, we recommend special individualized oral diets combined with food supplements and enteral and parenteral diets in the treatment of ARC/AIDS patients.
研究人员目前预测,美国150万至200万艾滋病毒呈阳性的患者中,75%至80%将会发展成艾滋病患者。大多数艾滋病患者在死亡前会经历体重逐渐减轻和营养不良的情况。由于营养疗法已被明确证明对重症普通人群的临床病程和免疫状况有有益影响,因此绝不能忽视营养疗法在治疗营养不良的艾滋病相关综合征/艾滋病患者方面的潜在积极益处。鉴于艾滋病相关综合征/艾滋病药物治疗成本不断攀升以及预计的艾滋病流行情况,艾滋病相关综合征/艾滋病营养治疗方案必须易于实施且具有成本效益。在旧金山综合医院,我们制定了具体的营养筛查标准,试图确定那些将从营养疗法中获益最大的患者。在开始治疗之前,我们会对每位患者进行访谈、进行全面的体格检查、开展彻底的营养评估、评估他们的肠道功能,并计算他们每日的热量和蛋白质需求。选择合适的口服、肠内和肠外饮食对于成功治疗这些患者至关重要。由于所有艾滋病相关综合征/艾滋病患者在营养需求、饮食耐受性和肠道功能障碍程度方面都存在差异,因此没有单一的营养治疗方案可用于治疗所有这些患者。因此,我们建议在治疗艾滋病相关综合征/艾滋病患者时采用特殊的个体化口服饮食,并结合食物补充剂以及肠内和肠外饮食。
