The Effect of Soy Nut Compared to Cowpea Nut on Body Weight, Blood Cells, Inflammatory Markers and Chemotherapy Complications in Children with Acute Lymphoblastic Leukemia: A Randomized Controlled Clinical Trial

Nutritional interventions in children with acute lymphoblastic leukemia undergoing antineoplastic treatment: a systematic review

BACKGROUND

A compromised nutritional status jeopardizes a positive prognosis in acute lymphoblastic leukemia (ALL) patients. In low- and middle-income countries, ~ 50% of children with ALL are malnourished at diagnosis time, and undergoing antineoplastic treatment increases the risk of depleting their nutrient stores. Nutrition interventions are implemented in patients with cancer related malnutrition. We aimed to evaluate the effect of nutrition interventions in children diagnosed with ALL under treatment.

METHODS

Using a predefined protocol, we searched for published or unpublished randomized controlled trials in: Cochrane CENTRAL, MEDLINE, EMBASE, LILACS, and SciELO, and conducted complementary searches. Studies where at least 50% of participants had an ALL diagnosis in children ≤ 18 years, active antineoplastic treatment, and a nutrition intervention were included. Study selection and data extraction were conducted independently by three reviewers, and assessment of the risk of bias by two reviewers. Results were synthesized in both tabular format and narratively.

RESULTS

Twenty-five studies (out of 4097 records) satisfied the inclusion requirements. There was a high risk of bias in eighteen studies. Interventions analyzed were classified by compound/food (n = 14), micronutrient (n = 8), and nutritional support (n = 3). Within each group the interventions and components (dose and time) tested were heterogeneous. In relation to our primary outcomes, none of the studies reported fat-free mass as an outcome. Inflammatory and metabolic markers related to nutritional status and anthropometric measurements were reported in many studies but varied greatly across the studies. For our secondary outcomes, fat mass or total body water were not reported as an outcome in any of the studies. However, some different adverse events were reported in some studies.

CONCLUSIONS

This review highlights the need to conduct high-quality randomized controlled trials for nutrition interventions in children with ALL, based on their limited number and heterogeneous outcomes.

The Effect of Nutritional Support Based on the Dietary Anti-Inflammatory Index on Cancer-Related Fatigue in Lung Cancer Patients Undergoing Chemotherapy

BACKGROUND

Cancer-related fatigue is one of the most common symptoms reported by cancer patients and is considered to be related to inflammation.

OBJECTIVE

This study aimed to explore the effects of nutritional support based on the dietary anti-inflammatory index on cancer-related fatigue in lung cancer patients undergoing chemotherapy.

METHODS

This was a randomized controlled trial with 106 lung cancer patients who were divided into either the anti-inflammatory diet group (n = 53) or the usual diet group (n = 53) for 3 months. The primary outcome was cancer-related fatigue. Secondary outcomes included high sensitivity C-reactive protein (hs-CRP) concentrations, nutritional status, and quality of life. Repeated-measures analysis of variance was used to examine the effectiveness of this intervention.

RESULTS

The anti-inflammatory diet improved fatigue (-1.99 ± 1.78, P < .001), hs-CRP levels (-4.15 [-11.87, -0.58], P < .001), Patient-Generated Subjective Global Assessment (-2.53 ± 3.11, P = .030), and albumin concentrations (2.83 ± 0.59, P < .001) compared with the usual diet after 3 months. Simultaneously, in the repeated-measures analysis of variance, the differences in fatigue ( F = 5.536, P < .001), hs-CRP levels ( F = 6.918, P < .001), and albumin concentrations ( F = 2.727, P = .048) were statistically significant for the group-by-time interaction.

CONCLUSION

The study provided evidence for the positive effect of nutritional support based on the dietary anti-inflammatory index on cancer-related fatigue, hs-CRP levels, nutritional status, and quality of life in lung cancer patients undergoing chemotherapy.

IMPLICATION FOR PRACTICE

With an anti-inflammatory diet, nurses can help these patients improve their overall quality of life.

Effects of soy intake on circulating levels of TNF-α and interleukin-6: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

Pro-inflammatory mediators, including serum tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6), can be used as biomarkers to indicate or monitor disease. This study was designed to ascertain the effects of soy products on TNF-α and IL-6 levels.

METHODS

PubMed, EMBASE, Science Direct, Web of Science, Google Scholar and the Cochrane Central Register of Controlled Trials were searched to November 2019 for RCTs around the effects of soy-based products on TNF-α and IL-6. A random effects model was used to calculate overall effect size.

RESULTS

In total, 29 eligible publications were considered in the present systematic review, of which 25 were included in this meta-analysis. The overall effect of soy products on TNF-α and IL-6 levels failed to reach statistical significance (MD = - 0.07; 95% CI - 0.22-0.09; I² 50.9; MD = 0.03; 95% CI - 0.07-0.14; I² 42.1, respectively). According to a subgroup analysis, natural soy products led to a reduction in TNF-α concentration compared with processed soy products (MD = - 0.32; 95% CI - 0.45 to - 0.19; I² 0.0). Moreover, IL-6 reduction was stronger in participants who were affected by different diseases (MD = - 0.04; 95% CI - 0.07 to - 0.02; I² 0.0).

CONCLUSIONS

A review of RCTs published to November 2019 found that natural soy products are effective in lowering TNF-α levels. While the beneficial effects on reduction of IL-6 appeared stronger in individuals affected by different diseases, this finding cannot be generalized to all individuals affected by different diseases.
