【摘要】过敏性紫癜累及肾脏即为紫癜性肾炎，多见于儿童与青少年，成人发病也逐年增多。该病属于免疫介导的血管炎性损伤，临床常伴随蛋白尿、血尿，严重者可影响肾功能。药物治疗是基础，而科学食膳干预，作为非药物手段，能够减少过敏原刺激、减轻肾脏代谢负担，辅助稳定病情，降低复发风险，在慢病综合管理中发挥重要的作用。食膳干预是全程管理的重要组成部分。

【关键词】紫癜性肾炎食膳干预

【论述研讨】

1、规避可疑致敏食物：发病急性期严格管控海鲜、虾蟹、牛羊肉、芒果、菠萝等常见高致敏食材；暂停辛辣刺激、加工腌制食品。个体化排查食物过敏原，减少免疫炎症诱发因素。

2、蛋白质分阶段管控：急性期存在大量蛋白尿时，限制高蛋白摄入，优先选用优质低蛋白食物，如少量鸡蛋蛋白、低脂牛奶；病情缓解稳定后，在肾内科医生指导下逐步调整蛋白总量，避免过量蛋白加重肾小球滤过负担。

3、低盐饮食保护肾脏：限制食盐摄入，减少水钠潴留，减轻水肿与高血压风险，每日根据水肿、血压情况控制盐量，拒绝咸菜、酱品、各类重口味预制菜。

4、食材选择兼顾药食同源：选用性质平和的药食同源食材，兼顾健脾、凉血、利水等食疗思路，规避寒凉峻猛食材。同时兼顾维生素补充，优先选择低致敏新鲜蔬果。

【总结】紫癜性肾炎是免疫相关肾脏疾病，反复发作与饮食、感染等诱因密切相关。科学食膳干预通过控敏、控盐、合理蛋白管理，减少炎症刺激，减轻肾脏负荷，配合规范医疗方案，有助于改善患者整体状态，降低复发概率。把食养纳入紫癜性肾炎全周期健康管理体系，是疾病非药物干预的重要实践方向。

【Abstract】Allergic purpura inflicing the kidney is purpuric nephritis, which is more common inchildren and adolescents, and the incidence of adults is also increasing year by year. The disease is an immune-mediated vasculitis injury, which is often accompanied by proteinuria and haematuria in clinical practice, and severe cases can affect kidney function. Drug treatment is the foundation, and scientific dietary intervention, as a non-drug means, can reduce allergin stimulation, reduce the metabolic burden of the kidney, help stabilise the disease, reduce the risk of recurrence, and play an important role in the comprehensive management of chronic diseases. Diet intervention is an important part of the whole process of management.

【Keyword】Dietal intervention for purpuric nephritis

【Discussion】

1. Avoid suspicious sensitising foodIn the acute stage of the disease, strictly control seafood, shrimp and crab, beef and mutton, mango,pineapple and other common highly sensitive ingredients; suspend spicy and stimulating and processed pickled foods. Individualise the investigation of food allergens to reduce the triggers of immune inflammation.

2. Protein is controlled in stages

When there is a large amount of proteinuria in the acute stage, limit the intake of high protein, and give priority to high-quality low-protein foods, such as a small amount of egg protein and low-fat milk; after the condition is relieved and stabilised, gradually adjust the total amount of protein under the guidance of a nephrologist to avoid excessive protein and aggravate the burden of glomerular filtration.

3. A low-salt diet protects the kidney

Limit salt intake, reduce water and sodium retention, reduce the risk of oedema and hypertension, control the amount of salt daily according to oedema and blood pressure, and refuse pickles, sauces and all kinds of heavy-flavoured pre-cooked dishes.

4. The choice of ingredients takes into account the same origin of medicine and food. Choose medicinal food ingredients of the same origin with peaceful nature, take into account the ideas of food therapy such as strengthening the spleen, cooling the blood, and benefitting water, and avoid cold and fierce ingredients. At the same time, take into account vitamin supplementation, and give priority to low-allergenic fresh fruits and vegetables.

【Summary】Purpura nephritis is an immune-related kidney disease. Repeated attacks are closely related to diet, infection and other triggers. Scientific dietary intervention reduces inflammatory stimulation, reduces kidney load, and cooperates with standardised medical plans, which helps to improve the overall condition of patients and reduce the probability of recurrence through sensitivity control, salt control and reasonable protein management. Integrating diet into the full-cycle health management system of purpuric nephritis is an important practical direction for non-drug

intervention in diseases.
