Alimentary and Pharmaceutical Approach to Natural Antimicrobials against Clostridioides difficile Gastrointestinal Infection
Incidence of Clostridioides difficile infection (CDI) has been increasing in recent decades due to different factors, namely (i) extended use of broad-spectrum antibiotics, (ii) transmission within asymptomatic and susceptible patients, and (iii) unbalanced gastrointestinal microbiome and collateral diseases that favor C. difficile gastrointestinal domination and toxin production. Although antibiotic therapies have resulted in successful control of CDI in the last 20 years, the development of novel strategies is urged in order to combat the capability of C. difficile to generate and acquire resistance to conventional treatments and its consequent proliferation. In this regard, vegetable and…
Nitric oxide production is increased in severely obese children and related to markers of oxidative stress and inflammation
Nitric oxide (NO) is the major endothelium-derived relaxing factor. The aim of the present study was to evaluate NO synthesis and metabolism in severely obese children with different degrees of metabolic risk and to ascertain their relation with the parameters of oxidative stress and inflammation.The study involved 60 obese children evaluated with respect to metabolic risk factors (MRFs) (324 MRFs and 28 ≥ 4 MRFs) and 50 normal weight children between 7 and 14 years of age. Nutritional status was assessed by clinical and anthropometric examination. MRFs (serum lipid profile, insulin resistance indexes, blood pressure) in addition to uric acid, homocysteine, leptin, and inflammatory markers …

Elevated advanced oxidation protein products (AOPPs) indicate metabolic risk in severely obese children.
Abstract Background and aims The assessment of oxidative stress may aid in the identification of subsequent metabolic risk in obese children. The objective of this study was to determine whether the plasma level of advanced oxidation protein products, analyzed with a recently proposed modified assay that involves a delipidation step (mAOPPs), was related to metabolic risk factors (MRFs) in severely obese children. Methods and results The plasma levels of mAOPPs were determined by spectrophotometry in 54 severely obese and 44 healthy children. We also measured lipid peroxidation biomarkers (thiobarbituric acid-reactive substances, malondialdehyde, and 8-isoprotane F 2α ) and sulfhydryl group…
Personalized medicine for allergy treatment: Allergen immunotherapy still a unique and unmatched model
International audience; The introduction of personalized medicine (PM) has been a milestone in the history of medical therapy, because it has revolutionized the previous approach of treating the disease with that of treating the patient. It is known today that diseases can occur in different genetic variants, making specific treatments of proven efficacy necessary for a given endotype. Allergic diseases are particularly suitable for PM, because they meet the therapeutic success requirements, including a known molecular mechanism of the disease, a diagnostic tool for such disease, and a treatment blocking the mechanism. The stakes of PM in allergic patients are molecular diagnostics, to dete…

Caenorhabditis elegans as an in vivo model to assess fucoidan bioactivity preventing Helicobacter pylori infection
Currently, Helicobacter pylori is the unique biological carcinogenic agent. The search for antimicrobial alternatives to antibiotics against this pathogen has been categorized as a priority due to the drastic failure associated with current applied antibiotic therapy. The present study assessed the bioactive antimicrobial capability of fucoidan (“Generally Recognized as Safe” approval – European Commission December 2017) from different species of Phaeophyceae algae (Fucus vesiculosus, Undaria pinnatifida, Macrocystis pyrifera) against H. pylori. All the studied fucoidans showed bacteriostatic and bactericidal effects at the studied concentrations [5–100] μg ml−1 and exposure times [0–7 days…
Asthma diagnosis in infants and preschool children: a systematic review of clinical guidelines.
Background and aim: The definition and diagnosis of asthma are the subject of controversy that is particularly intense in the case of individuals in the first years of life, due to reasons such as the difficulty of performing objective pulmonary function tests or the high frequency with which the symptoms subside in the course of childhood. Since there is no consensus regarding the diagnosis of asthma in preschool children, a systematic review has been carried out. Materials and methods: A systematic search was made of the clinical guidelines published in the last 10 years and containing information referred to the concept or diagnosis of asthma in childhood - including the first years of l…

How bilastine is used to treat allergic rhinitis and urticaria in children
Management guidelines for allergic rhinitis and urticaria recommend oral second-generation antihistamines as first-line treatment. The efficacy and safety of bilastine, the newest nonsedating second-generation antihistamine, are well established in adolescents/adults with these allergic conditions. The bilastine development program for pediatric use (2–<12 years) followed EMA-authorized processes. Pharmacokinetic/pharmacodynamic simulation and modeling and a pharmacokinetic study were conducted to identify and confirm the pediatric dose (10 mg/day). A Phase III, multicenter, double-blind, randomized, placebo-controlled, parallel-group study was performed to confirm the safety of bilasti…

Spontaneous pneumomediastinum and subcutaneous emphysema as a complication of asthma in children: case report and literature review
Background:Spontaneous pneumomediastinum (SPM) is an uncommon disorder. It is rarely reported in paediatric patients and may be accompanied by subcutaneous emphysema. It is usually benign and self-limiting, with only supportive therapy being needed, but severe cases may require invasive measures. Asthma exacerbations have classically been described as a cause of SPM. However, detailed descriptions in asthmatic children are scarce. We aimed at improving the current understanding of the features of SPM and subcutaneous emphysema, and outcomes, by means of a case report and a systematic review.Methods:For the systematic review a literature search was performed in PubMed to identify reported ca…

Vitamin D receptor gene ApaI and FokI polymorphisms and its association with inflammation and oxidative stress in vitamin D sufficient Caucasian Spanish children
Background Vitamin D has gone from being just one vitamin to being an important prohormone with multiple effects on different tissue types. The mechanism of action of the active form or calcitriol is mediated by the intracellular vitamin D receptor (VDR). The interaction of the VDR with calcitriol modulates the expression of target genes involved in cell proliferation and cytokine production. Several studies have explored the effects of vitamin D deficiency in inflammatory disorders. Furthermore, some mutations in the VDR can affect its functionality. The focus of this study was to explore associations between VDR single nucleotide polymorphisms (SNPs) and markers of inflammation and oxidat…
Evidence in immunotherapy for paediatric respiratory allergy: Advances and recommendations. Document of the Immunotherapy Working Group of the Spanish Society of Pediatric Clinical Immunology and Allergology (SEICAP)
Allergic respiratory diseases are major health problems in paediatric population due their high level of prevalence and chronicity, and to their relevance in the costs and quality of life. One of the most important risk factors for the development of airway diseases in children and adolescents is atopy. The mainstays for the treatment of these diseases are avoiding allergens, controlling symptoms, and preventing them through sustained desensitization by allergen immunotherapy (AIT). AIT is a treatment option that consists in the administration of increasing amounts of allergens to modify the biological response to them, inducing long-term tolerance even after treatment has ended. This treat…
Impact of adenotonsillectomy on the evolution of inflammatory markers
Background Tonsils are first-line host defence organs against pathogenic agents and participate in local and systemic immunity. Persistent increases in systemic inflammatory responses may contribute to associated morbidity. The aim of this study was to verify the short- and long-term impact of adenotonsillectomy on the evolution of inflammatory markers in 3- to 9-year-old children. Methods A prospective and longitudinal study was conducted over 1 year in 29 children who underwent tonsillectomy due to either chronic tonsillitis or adenotonsillar hypertrophy. Measurements of high-sensitivity C-reactive protein (hs-CRP) levels were taken. Levels of Th1-type cytokines [interleukin-1, interferon…
