Sickle Cell Anemia (SCA) is a hereditary hemoglobinopathy characterized by chronic hemolytic anemia, vaso-occlusive events, and a wide range of clinical complications. Malnutrition, often an underexplored aspect of this complex condition, plays a critical role in disease management and overall patient well-being. This publication provides a comprehensive review of the prevalence, impact, and interventions related to malnutrition in individuals with SCA. A thorough literature review reveals the multifaceted challenges faced by SCA patients in maintaining adequate nutrition. The pathophysiology of SCA, involving chronic inflammation, oxidative stress, and hypermetabolism, contributes to increased nutritional requirements and altered dietary patterns. Factors such as reduced appetite, nutrient malabsorption, dietary restrictions, and socioeconomic disparities further exacerbate the risk of malnutrition. Malnutrition is a prevalent issue among individuals with SCA, affecting patients of different age groups and disease severities. Nutritional deficiencies, including vitamins, minerals, and essential nutrients, are common in this population. The impact of malnutrition on disease outcomes is significant, with associations between nutrient status and complications such as pain crises, infections, and impaired quality of life. This paper also reviews nutritional interventions aimed at addressing malnutrition in SCA patients. While dietary counseling, supplementation, and personalized nutrition plans have shown promise in improving nutritional status, challenges such as patient adherence and access to healthcare must be addressed to optimize their effectiveness.
镰状细胞贫血症 (SCA) 是一种遗传性血红蛋白病,其特征为慢性溶血性贫血、血管阻塞事件以及广泛的临床并发症。营养不良是这种复杂疾病中常常被忽视的一个方面,在疾病管理和整体患者健康方面起着关键作用。本出版物全面回顾了 SCA 个体中营养不良的流行率、影响和干预措施。全面的文献回顾揭示了 SCA 患者在维持充足营养方面面临的多方面挑战。SCA 的病理生理学涉及慢性炎症、氧化应激和高代谢,导致营养需求增加和饮食模式改变。食欲下降、营养吸收不良、饮食限制和社会经济差异等因素进一步加剧了营养不良的风险。营养不良是 SCA 个体中的一个普遍问题,影响不同年龄组和疾病严重程度的患者。营养缺乏症,包括维生素、矿物质和必需营养素,在这一人群中很常见。营养不良对疾病结局有显著影响,营养状况与疼痛危机、感染和生活质量受损等并发症之间存在关联。本文还回顾了旨在解决 SCA 患者营养不良问题的营养干预措施。尽管饮食咨询、补充剂和个性化营养计划已显示出改善营养状况的潜力,但必须解决患者依从性和获得医疗保健方面的挑战,以优化其效果。
