Abstract
OBJECTIVE Despite repeated public health interventions, anemia prevalence among children remains a concern. We use an evolutionary medicine perspective to examine the intestinal microbiome as a pathway underlying the efficacy of iron-sulfate treatment. This study explores whether gut microbiota composition differs between anemic children who respond and do not respond to treatment at baseline and posttreatment and if specific microbiota taxa remain associated with response to iron supplementation after controlling for relevant inflammatory and pathogenic variables. METHODS Data come from 49 pre-school-aged anemic children living in San Juan de Lurigancho, Lima, Peru. We tested for differences in alpha and beta diversity using QIIME 2 and performed differential abundance testing in DESeq2 in R. We ran multivariate regression models to assess associations between abundance of specific taxa and response while controlling for relevant variables in Stata 17. RESULTS While we found no evidence for gut microbiota diversity associated with child response to iron treatment, we observed several differential abundance patterns between responders and non-responders at both timepoints. Additionally, we present support for a nonzero relationship between lower relative abundance of Barnesiellaceae and response to iron supplementation in samples collected before and after treatment. CONCLUSION While larger studies and more specific approaches are needed to understand the relationship between microbes and anemia in an epidemiological context, this study suggests that investigating nutritional status and pathogen exposure is key to better understanding the gut microbiome and impact of iron fortification.

Intestinal microbiota dataset revealed by high-throughput sequencing of 16S rRNA in children with anemia in southern Peru. Data Brief 2024; 55:110681. [PMID: 39081489 PMCID: PMC11287011 DOI: 10.1016/j.dib.2024.110681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 06/19/2024] [Accepted: 06/20/2024] [Indexed: 08/02/2024] Open
Abstract
Anemia is the most common hematological disorder affecting humans. In Peru, anemia is a pressing issue that present the most significant concern due to its adverse effects, such as delayed growth and psychomotor development, in addition to a deficiency in cognitive development. Anemia is a significant public health issue in Peru, which has one of the highest prevalence rates in infants in the Latin American and Caribbean (LAC) region, affecting approximately 43.6 % of children under three years nationally as of 2017, with rural areas experiencing a higher prevalence of approximately 53.3 %. In 2019, the prevalence was highest in the Sierra (48.8 %) and Selva regions (44.6 %), whereas the coast had a lower rate of 33.9 % in children under 36 months. Although the composition of the gut microbiota is relatively well described in children, there is little information on the identification of the microbiota in iron-deficiency anemia. There is evidence that diseases or health conditions can change the microbiota, or vice versa. This study aimed to identify the microbiota in children with anemia who did not recover after iron treatment. In a previous study, we found that the phylum Actinobacteria was predominant in the microbiota of children with anemia. These data will be useful for understanding the functionality of the most important bacteria found in each group at the genus or species level, especially the metabolic pathways in which they participate and their links with iron metabolism. Microbial composition data were obtained through next-generation 16S rRNA sequencing (NGS) of stool samples from children with anemia in southern Peru. Numerous studies have underscored the importance of early symbiotic development in infant health and its long-term impact on health. From infancy, modulation of the gut microbiota can promote long-term health. According to the National Institute of Health (NIH), iron-deficiency anemia may cause serious complications, such as fatigue, headaches, restless legs syndrome, heart problems, pregnancy complications, and developmental delays in children. The development of the gut microbiota is regulated by a complex interplay between host and environmental factors. The bidirectional link between the gut microbiota and anemia plays an important role in tracking the gut microbiota and will be useful in understanding the composition of the intestinal microbiota and its implications in anemia, which has now become a public health problem. Our previous study investigated the microbial composition in children with iron-deficiency anemia and revealed the presence of several bacterial groups, including Proteobacteria, Actinobacteria, Firmicutes, and Chloroflexi. In addition, these data may be useful for investigating the association between the intestinal microbiota of children with persistent anemia and those who have recovered.

Abstract
Several strategies, programs and policies have long been developed and implemented to alleviate child malnutrition in sub-Saharan African countries. However, stunting and wasting still persist at an alarming rate, suggesting that alternative strategies are needed to induce faster progress toward the 2030 SDGs targets of reducing malnutrition. Gut microbiota-directed intervention is now being recognized as an unconventional powerful approach to mitigate malnutrition and improve overall child health. In an African setting, manufactured probiotic and synbiotic foods or supplements may not be successful owing to the non-affordability and high attachment of African populations to their food tradition. This review analyses the potential of indigenous fermented cereal-based products including porridges, doughs, beverages, bread- and yoghurt-like products, to be used as microbiota-directed foods for over 6 months children. The discussion includes relevant strategies to effectively enhance the beneficial effects of these products on gut microbiota composition for improved child health and nutrition in sub-Saharan Africa. Characterization of probiotic features and general safety of food processing in sub-Saharan Africa as well as randomized clinical studies are still lacking to fully ascertain the health effects and suitability of these fermented foods in preventing and treating child malnutrition and diarrhea.

Abstract
Sequence variation in the 16S gene is widely used to characterize diverse microbial communities. This was the first pilot study carried out in our region where the pulmonary microbiota of critically ill patients was investigated and analyzed, with the aim of finding a specific profile for these patients that can be used as a diagnostic marker. An study of critical patients mechanically ventilated for non-respiratory indications, in a polyvalent intensive care unit, was carried out; samplee were extracted by endotracheal aspiration and subsequently the microbiota was characterized through Next-Generation Sequencing Technology (NGS). The predominant phyla among the critically ill patients were Proteobacteria, Firmicutes and Bacteroidata. In the surviving patients group, the predominant phyla were Proteobacteria, Bacteroidata and Firmicutes, in the group of deceased patients thy were Firmicutes, Proteobacteria, and Bacteroidata. We found a decrease in commensal bacteria in deceased patients and a progressive increase in in-hospital germs.

Abstract
BACKGROUND Anaemia of chronic disease (ACD) is the second most common type of anaemia and lacks an effective treatment. Patients with anaemia are reported to have altered gut microbial profiles, which may affect erythropoiesis. Here, we investigated the gut microbial features of patients with ACD and determined whether regulating gut microbiota using washed microbiota transplantation (WMT) was effective in treating ACD. METHODS We compared the gut microbiota profile of patients with ACD and healthy controls, evaluated the efficacy of WMT on haematological parameters in the patients, and analysed the alterations in gut microbiota after WMT treatment. RESULTS Patients with ACD had lower gut microbial richness, and differences in microbial composition and function, relative to healthy controls. Additionally, the relative abundances of two butyrate-producing genera Lachnospiraceae NK4A136 group and Butyricicoccus, were positively correlated with the haemoglobin (HGB) level and lower in patients with ACD than controls. WMT significantly increased HGB levels in patients with ACD. After the first, second and third WMT rounds, normal HGB levels were restored in 27.02%, 27.78% and 36.37% (all p < .05) of patients with ACD, respectively. Moreover, WMT significantly increased the abundance of butyrate-producing genera and downregulated gut microbial functions that were upregulated in patients with ACD. CONCLUSIONS Patients with ACD exhibited differences in gut microbial composition and function relative to healthy controls. WMT is an effective treatment for ACD that reshapes gut microbial composition, restores butyrate-producing bacteria and regulates the functions of gut microbiota.
