Neutropenic diet(ND) has been hypothesized to decrease the rate of febrile neutropenia(FN) occurring post-chemotherapy for pediatric cancers. Despite widespread use, it has not shown to be of benefit by randomized controlled trials(RCT) in western countries. No RCT has been conducted in India/LMIC to evaluate its efficacy against the standard Indian diet. Forty-two(42) children, aged 3-14 y, with cancer, scheduled to receive strongly myelosuppressive chemotherapy were randomized to receive either neutropenic diet( = 21) or standard Indian diet( = 21) for one chemotherapeutic cycle. FN rate was recorded as the primary outcome while the focus of infection, antibiotic length, the requirement for hospital admission, adherence to diet were the secondary outcomes. The groups were similar in baseline characteristics. Twelve patients (57%) in the neutropenic diet and nine patients(43%) in the standard diet arm developed FN. Patients in ND-arm had significantly higher chance of getting neutropenic enterocolitis(NEC) (33.33% vs 4.76% = 0.044). Mortality (14.29%vs 0%, = 0.23) and requirement for admission (47.6%vs 19.05%, = 0.06), was more in the ND-arm but statistically non-significant. There was no significant difference in antibiotic length. Adherence was similar in both groups (95% vs 98%). Neutropenic diet was not effective in reducing FN rate and was associated with higher rate of NEC when compared to the standard diet.
中性粒细胞减少症饮食(ND)被假设可以降低儿科癌症化疗后发热性中性粒细胞减少症(FN)的发生率。尽管广泛使用,但在西方国家的随机对照试验(RCT)中并未显示其有益。印度/中低收入国家尚未进行 RCT 来评估其对标准印度饮食的疗效。42 名(42 名)年龄在 3-14 岁之间、患有癌症的儿童计划接受强烈骨髓抑制化疗,随机分为接受中性粒细胞减少症饮食(=21)或标准印度饮食(=21)一个化疗周期。FN 发生率作为主要结局,而感染焦点、抗生素使用时间、住院需求、饮食依从性作为次要结局。两组在基线特征上相似。中性粒细胞减少症饮食组中有 12 名患者(57%)和标准饮食组中有 9 名患者(43%)发生 FN。ND 组发生中性粒细胞减少性肠炎(NEC)的几率明显更高(33.33%比 4.76%,=0.044)。死亡率(14.29%比 0%,=0.23)和住院需求(47.6%比 19.05%,=0.06)在 ND 组更高,但统计学上无显著性差异。抗生素使用时间无显著差异。两组的依从性相似(95%比 98%)。与标准饮食相比,中性粒细胞减少症饮食在降低 FN 发生率方面无效,并且与更高的 NEC 发生率相关。
