ABSTRACT

Allergy to natural rubber latex emerged as one of the main allergies at the beginning among some professional groups and the general population. Sensitization and development of latex allergy have been attributed to exposure to products containing residual latex proteins. The prevailing cross-reactivity of latex proteins with other food allergens is of great concern. Numerous purified allergens are currently available, which greatly help in patient management, thus determining their specific profile. We conducted a multicenter study to investigate changes, from the ROC analysis, in the characteristics of patients with latex allergy by measuring its major protein components. Sensitization to latex proteins is crucial because it highlights the cross reactivity to inhalants (pollen) and food (fruit). It is very essential in an accurate and specific clinical setting.

ABSTRACT

OBJECTIVE: From September 2020, a second wave of COVID-19 pandemic started. We aimed at exploring the impact of SARS-CoV-2 infection in IBD patients during the two waves. PATIENTS AND METHODS: All IBD patients with a confirmed diagnosis of SARS-CoV-2 infection were enrolled. They were sorted into two groups (those infected before September 2020, and those from September 2020 to January 2021) and compared by demographic and clinical data. RESULTS: Twenty-five patients (out of about 600 with a follow-up visit) were infected with SARS-CoV-2 (4.1%). Sixteen were male and the mean age was 46.5 ± 14.3 years (range 24-74). Six were smokers and 11 had comorbidities; 2 were on steroids and 17 on immunosuppressants or biologics. Three patients (12%) needed hospitalization and other three patients were treated with azithromycin, steroids and LMWH, all of them during the second wave. No patient died or developed any sequelae. Two subjects were infected during the first wave (0.3 vs. 3.83, p<0.0001). Non-significant differences were found between the two groups. CONCLUSIONS: A higher number of IBD patients were infected during the second wave. No patient developed a severe form of pneumonia, even those treated with immunosuppressants or biologics. No risk factor for hospitalization was found.

ABSTRACT

BACKGROUND: The natural history of prediabetes in older adults remains unknown. OBJECTIVES: To assess the rate at which prediabetes progresses to diabetes, leads to death or reverts to normoglycaemia in older adults and to identify prognostic factors related to different outcomes of prediabetes. METHODS: In the Swedish National Study on Aging and Care-Kungsholmen, 2575 diabetes-free participants aged ≥60 years were examined at baseline and followed for up to 12 years. At each wave, diabetes was diagnosed via medical examination, antidiabetic drug use, medical records or glycated haemoglobin (HbA1c) ≥6.5%. Prediabetes was defined as HbA1c ≥5.7% and normoglycaemia as HbA1c <5.7% in diabetes-free participants. Data were analysed with multinomial logistic regression. RESULTS: At baseline, 918 (36%) individuals had prediabetes. Of them, 204 (22%) reverted to normoglycaemia (3.4/100 person-years, 95% CI 5.6-12.3), 119 (13%) developed diabetes (2.0/100 person-years, 95% CI 1.7-2.4) and 215 (23%) died (13.0/100 person-years, 95% CI 11.4-14.9) during the 12-year follow-up. The rates of reversion, progression and mortality were higher in the first 6-year than in the second 6-year follow-up, albeit not statistically significant. Lower systolic blood pressure (SBP), absence of heart diseases and weight loss promoted the reversion from prediabetes to normoglycaemia, whilst obesity accelerated its progression to diabetes. CONCLUSIONS: During a 12-year follow-up, most of older adults with prediabetes remained stable or reverted to normoglycaemia, whereas only one-third developed diabetes or died. Lower SBP, no heart diseases and weight management may promote reversion to normoglycaemia, suggesting possible strategies for achieving normoglycaemia in older adults with prediabetes.

ABSTRACT

OBJECTIVES AND STUDY: Various degrees of biliary changes are considered to be part of the histological picture of children with pediatrics autoimmune liver disease (AILD), but the literature is scarce and confusing. We aimed to describe the characteristics of children with AILD (autoimmune hepatitis, AIH, and autoimmune sclerosing cholangitis, ASC) focusing on the prevalence and type of biliary abnormalities on initial biopsy to see whether ASC was predictable on histological ground. METHODS: The files of children diagnosed with AILD were reviewed. The Ishak score was used to grade inflammation and fibrosis on biopsy; a biliary score was built to grade bile duct injury. Demographic, laboratory and histological features at diagnosis were reported and compared between the two groups (AIH vs ASC). RESULTS: Forty-one patients were diagnosed with AIH (n = 24), ASC (n = 13) and PSC (n = 4) between 2009 and 2018. Twenty-nine patients [F = 76%, AIH = 20, ASC = 9, median age at diagnosis 11.7 (range 2.2-17.8)] were included in the study; 12 (4 with PSC) were excluded. Prevalence of inflammatory bowel disease was higher in ASC group (56% vs 10% in AIH, p < 0.05). On histology 17% had cirrhosis. The grade of biliopathy with AILD was moderate in 72% and severe in 31%, and overall more prominent in ASC (p = 0.031). The inflammation of the bile ducts was classified as "multifocal" or "diffuse" mainly in ASC patients (89% vs 45% in AIH, p = 0.043). Periductular fibrosis was reported in 52% of AILD patients, with a higher mean score in ASC group (p < 0.05). However, ductular reaction, biliary metaplasia and granulomatous cholangitis were equally reported in AIH and ASC, providing no clear-cut for the distinction of the two entities in the global histological evaluation. CONCLUSIONS: Majority of patients with pediatrics AILD have "moderate" or "severe" features of biliopathy; AIH and ASC are not easily distinguishable on histological ground at diagnosis, and therefore, the cholangiogram remains the only effective tool to differentiate patients with AIH from those with ASC. Further prospective studies are needed to better define histological biliary features in AILD, assess if the biliopathy responds to immunosuppressive treatment and evaluate its impact on long-term outcome.

ABSTRACT

Chocolate and cocoa-based products are among the goods with higher added value. A current trend of the cocoa market is to offer to the consumers high quality cocoa products, namely mono-origin cocoa. However, a reliable analytical method able to trace the geographical origin of cocoa is lacking. In this work we tested the capability of HR MAS 1H NMR combined with chemometrics to assess the geographical origins of 60 fermented and dried cocoa beans of 23 different cocoa producing countries from the three major crop-growing areas (Africa, Central/South America, Asia/Oceania). Metabolic profiling was determined by HR MAS 1H NMR directly on cocoa powder after the method optimization. The same samples were also subjected to extraction and analysis with HR 1H NMR. HR MAS 1H NMR, as 1H NMR analysis, allowed the simultaneous detection of amino acids, polyalcohols, organic acids, sugars, methylxanthines, catechins. Moreover, HR MAS allows the detection of lipids, not present in the aqueous extract utilized for 1H NMR. The data set obtained is therefore representative of all classes of cocoa compounds. Untargeted HR MAS 1H NMR and 1H NMR datasets were utilized as fingerprint of the samples and elaborated with multivariate statistical methods. A targeted quantitative approach of selected metabolites was possible only with HR 1H NMR data, because HR MAS 1H NMR does not give reliable quantitative results. All the approaches adopted showed a discrimination of the cocoa origins. HR MAS presents the advantages to obtain a very rapid picture of the samples, comprising both lipophilic and hydrophilic components, avoiding any sample manipulation.

ABSTRACT

Atopic dermatitis (AD) is a chronic inflammatory skin disease that commonly presents during early childhood. In the last decades the prevalence of AD has increased, especially in western societies. This frequently relapsing inflammatory condition has a strong impact on the quality of life of patients and families. The recent advances in the understanding of this disease have paved the way for the development of new strategies for the prevention and treatment of AD. Among the new therapeutic options, there is increasing interest in the potential benefit of probiotic supplementation. It has been widely demonstrated that the human microbiota plays a fundamental role not only in the maintenance of intestinal homeostasis through the interaction between microorganisms and the innate immune system, but also in the microbiota-mediated development of adaptive immunity. In addition, several studies have demonstrated that probiotics are able to influence the composition of gut microbiota and may exert immunomodulatory effects. According to these promising results, the possible application of probiotics in the therapeutic management of allergic diseases has been investigated in many studies. In particular, a considerable body of literature has been published analyzing the effects of probiotics on patients with AD. In order to shed light on frequently conflicting results, we reviewed the data regarding the application of probiotics in AD, with the aim to provide a state-of-the-art assessment of the most important studies exploring the role of probiotics both in the prevention and treatment of AD.

ABSTRACT

Allergic rhinitis (AR) is one of the most common diseases and represents a global health problem, currently affecting up to 30% of the general population, with a continuously increasing prevalence and significant comorbidities and complications. To date, the mainstay of current treatment strategies of AR includes allergen avoidance, pharmacotherapy and allergen-specific immunotherapy, as defined by Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines for both adults and children. The aim of this review is to provide an update on all emerging and future therapeutic options for the treatment of AR.

ABSTRACT

Walnut consumption has recently become a healthy dietary habit worldwide, due to its positive benefits in reducing cholesterol levels and oxidative stress; this has resulted in an increase in individual consumption, global production and risk of developing sensitization and allergy. In general, clinical manifestations of walnut allergy are frequently severe and systemic potentially life-threatening, leading to anaphylaxis both in the pediatric and adult populations. In light of these findings, we performed a preliminary study considering the walnut native allergen and the recombinant Jug r1 in order to evaluate their role in atopic diseases.

ABSTRACT

UNLABELLED: Allergic sensitization is mediated by immunoglobulin E (IgE) and an increase of their total value is frequently used to complete a correct diagnosis of atopy. Serum IgE may be considered a typical biomarker for the allergic phenotype. The aim of this study was to evaluate total serum IgE, according to sensitizations and to find a cut off to discriminate between atopic and non-atopic subjects. Seven hundred and ninety-five patients were enrolled in this study. Serum levels of total IgE were measured by a fluorescence immunoassay (ImmunoCAP; ThermoFisher, Uppsala, Sweden) while specific IgE levels were measured by immunofluorometric assay (ImmunoCAP; ThermoFisher, Uppsala, Sweden). Both tests were expressed in kU/L, according to manufacturer’s instructions. RESULTS: A difference for total IgE, according to the gender, has been found (p = 0,0012 ) with higher values for males than for females. A correlation has been found between total IgE and specific IgE, even distinguishing the population in sensitized and non-sensitized. A statistically significant difference has been found according to the presence or the absence of sensitization (p less than 0.0001) and also considering mono-sensitized and polysensitized patients (p less than 0.0001). ROC analysis has been performed to define a cut off for total serum IgE, according to sensitization and to the type of sensitization (mono-sensitization or poly-sensitization). Finally multiple regression models have been performed to describe total IgE response (positive or negative) and to predict total IgE values. Since clinical limitations are well known, total IgE provide a useful aid to define atopy, allowing the clinician to carry out further investigations in patients with total IgE values beyond normal limits.

ABSTRACT

AIM: Recurrent respiratory infections (RRI) constitute a social problem for both the pharmaco-economic impact and the burden for the family. Pidotimod is a synthetic immunostimulant. The aim of this study was to evaluate the effects of pidotimod on RRI prevention in children. METHODS: Globally, 100 children (49 males, mean age 4.7 ± 1.2 years) with RRI were enrolled in the study. At baseline, children were randomly assigned to the treatment with pidotimod 400 mg/die or not for two months. Children were visited at baseline, after 30 (T1) and 60 (T2) days, and at follow-up (120 days; T3). Number of children with upper and lower airways symptoms, medications use, school attendance, and paediatric visits for RRI were evaluated. RESULTS: Pidotimod treatment was able of significantly reducing the number of children with upper and lower airways symptoms, and medications use, increasing school attendance, and reducing pediatric visits for RRI. CONCLUSION: This study provided the evidence that pidotimod may be able of preventing RRI in children.

ABSTRACT

Antibiotic therapy, especially in pediatric patients, is often associated with significant modifications of the gut microflora, which can lead to intestinal dysbiosis and influence intestinal physiology and immune system functionality. Herein we report the results from a double blind controlled clinical trial in 77 pediatric patients affected by recurrent airway infections, receiving antibiotic therapy with amoxicillin and clavulanic acid. A group was treated with an oral probiotic preparation composed of Lactobacillus paracasei ssp.paracasei CRL-431, Bifidobacterium BB-12, Streptococcus thermophilus TH-4 and a fructooligosaccharide (FOS) during and after antibiotic therapy for seven days, while the other group received placebo. The study revealed a reduction in the Clostridia population, with a contemporary increase in Bifidobacteria and Lactobacilli in fecal samples in the probiotic group and an increase in the Enterobacteria population in the placebo group. Moreover, there was a decreasing trend in secretory IgA production in the probiotic group. Some relevant, but not statistically significant probiotic supplementation effects were identified.

ABSTRACT

Upper and lower airways may be considered as a unique entity, interested by coexisting inflammatory processes that share common etiopathogenic mechanisms. Previous studies have strongly demonstrated a relationship between rhinosinusitis and asthma. This has led to the introduction of the concept of “United Airways”, which has also been included in the WHO document Allergic Rhinitis and its Impact on Asthma (ARIA); this concept has important consequences also on the treatment of these disorders. To better summarize the evident connection between upper and lower airway disease we decided to describe it as a multilayered construction, each level pointing out more deeply the relationship between these entities.

ABSTRACT

PURPOSE: Lysozyme, obtained from egg white, is a potential food allergen used in the dairy industry to prevent late blowing of the loaf caused by the outgrowth of clostridial spores (Cl. butyricum and Cl. tyrobutyricum) during cheese aging. The aim of this study was to evaluate the possible correlation between egg protein allergy in pediatric age and sensitization to egg lysozyme, used for the preparation of Grana Padano cheese. METHODS: The tolerability of Grana Padano cheese has been evaluated in pediatric patients allergic to egg proteins through an oral provocation test with increasing amounts of cheese containing, or not, lysozyme at 12 and 24 months of aging. RESULTS: When lysozyme-sensitized children received 12-months aged and lysozyme-containing cheese, several immediate and late adverse reactions such as itching, abdominal pain, vomiting, nausea, dermatitis, rhinitis, bronchial asthma, urticaria, and angioedema were seen in 5 out of 21 subjects; only 1 out of 21 children showed an adverse reaction after challenge with 24-months-ripened lysozyme-containing cheese. CONCLUSIONS: There is a possible relationship between the severity of allergic reactions and the lysozyme-specific IgE level in blood. In particular vomiting, hypotension, and abdominal pain were present when IgE level was higher than 7 kU/L. A ripening time of 24 months may reduce allergy problems when lysozyme-containing cheese is given to sensitized subjects, probably due to the hydrolysis of antigenic epitopes during aging.

ABSTRACT

Adenoids removed for airway obstruction and-or recurrent infections have been studied to identify a possible mechanism to explain chronicity. In this regard, macrophages may play a relevant pathogenic role as well as neutrophils during bacterial infections and eosinophils in allergic inflammation. Therefore, this study aimed at investigating some mediators as surrogate markers of inflammation in children who had to undergo to adenoidectomy. Globally, 67 children (25 females, 42 males, mean age 4.9 years), affected by persistent obstruction caused by adenoid hypertrophy were consecutively enrolled into the study. Blood samples were collected from patients and controls to determine serum CD163, Myeloperoxidase (MPO) and ECP. There were significant differences between patients and controls for serum CD163 (p less than 0.0001); MPO (p less than 0.0001); serum ECP (p less than 0.0001). This study demonstrated some risk factors for severe AH: apnoea, recurrent respiratory infections, and high serum CD163 levels.

ABSTRACT

Nasal polyposis is a chronic inflammatory disease affecting the nasal cavity and the paranasal sinuses. It is a relatively common disease, occurring in 1-4 % of the general population, but it is rarely described in the pediatric population. Most of the published series include children presenting with other underlying systemic diseases, mainly cystic fibrosis. The aim of the present study was to describe the characteristics of the patients suffering from nasal polyposis, evaluated at the Pediatric Clinic of the University of Pavia (Italy) over the last 17 years. 56 consecutive pediatric patients referring to our Pediatric Department had a diagnosis of nasal poyposis over the last 17 years. All children underwent allergy evaluation, nasal endoscopy, CT scan of the paranasal sinus, and Functional Endoscopic Sinus Surgery. The mean age of the present cohort was of 11.8 years and most of the patients were male. 50% of the patients presented with unilateral, polyposis, mostly with a diagnosis of antrochoanal polyp. 4 patients presenting with bilateral polyposis suffered from cystic fibrosis. Main symptoms at diagnosis included nasal obstruction, snoring and rhinorrhea 32% of the patients presented at least a positivity to skin prick test, for major inhalant and food allergens. Nasal polyposis in children could represent an alert sign for other underlying systemic diseases. Nasal endoscopy should therefore be prescribed when a diagnosis is suspected. To properly treat a patient presenting with nasal polyposis, it is necessary to integrate medical and surgical skills through a multidisciplinary approach.

ABSTRACT

PTX3 behaves as an acute-phase response protein as its blood levels rapidly and dramatically increase during endotoxic shock, sepsis, and other inflammatory and infectious conditions. Therefore, this study was designed to investigate a possible role of PTX3 in children with Atopic Dermatitis (AD). One-hundred-and-thirty-six patients (37 females, 99 males, mean age 10.4 years) were enrolled in the study. One hundred patients (74%) had only respiratory symptoms (allergic rhinitis and/or bronchial asthma); thirty-six patients (26%) showed dermatitis associated with respiratory allergy (allergic rhinitis and/or bronchial asthma). PTX3 levels were higher in children with AD and there was a significant correlation between serum PTX3 levels and SCORAD index (p-value=0.0001, rho=0.658). Therefore, this study may show that PTX3 might be a reliable marker for the severity of AD in children with respiratory allergy.

ABSTRACT

Hypersensitivity reactions after immunization with tetanus toxoid are occasionally observed in atopic and non-atopic individuals. High IgE levels in infancy may predict subsequent allergy. The aims of this study were: i) to evaluate the role of specific IgE to tetanus toxoid in children in response to tetanus immunization and the possible factors associated with specific IgE levels, and ii) to investigate the correlation between specific IgE levels to tetanus toxoid and the late development of allergy (up to 12 years). Initially, 278 healthy infants (152 males and 126 females, aged 12 months) living in an urban city were screened for serum total IgE and specific IgE to tetanus toxoid, after having obtained informed consent from parents. After 12 years, 151 children could be evaluated. Total IgE summed with tetanus specific IgE were significantly associated with allergy at 12 years. In conclusion, this study demonstrates that serum total IgE and tetanus specific IgE may be predictive of subsequent allergy onset.

ABSTRACT

Sinusitis is frequently associated with asthma. The diagnosis and management of patients with asthma associated with sinusitis are often challenging, though sometimes unsatisfactory. Detection and treatment of sinusitis in asthmatics may lead to a better control of asthma symptoms. Most of the studies regarding the relationship between sinusitis and asthma have been conducted in adults. The aim of the present study was to evaluate the presence of sinusal comorbidity in children with un-controlled asthma both clinically and through nasal endoscopy after the first 6 months of treatment. The present study included 294 consecutive asthmatic children (97 males, mean age 7.3 years). Asthma diagnosis, severity assessment and treatment were performed according to GINA guidelines. Twenty-one patients with non-controlled asthma presented with endoscopic features of sinusitis, but without any clinical sign or symptom. We defined such condition occult sinusitis. Not only overt sinusitis, but also occult sinusitis could be a significant comorbidity in asthmatic patients. For this reason, it may be beneficial to determine the presence of sinus inflammation in children with non-controlled asthma, even when they do not present clinical signs or symptoms of upper airways involvement.
