Abstract
BACKGROUND The epidemiology of inflammatory bowel disease (IBD) in developing countries may uncover etiopathogenic factors. We investigated IBD prevalence in Brazil by investigating its geographic, spatial, and temporal distribution, and attempted to identify factors associated with its recent increase. METHODS A drug prescription database was queried longitudinally to identify patients and verify population distribution and density, race, urbanicity, sanitation, and Human Development Index. Prevalence was calculated using the number of IBD patients and the population estimated during the same decade. Data were matched to indices using linear regression analyses. RESULTS We identified 162 894 IBD patients, 59% with ulcerative colitis (UC) and 41% with Crohn's disease (CD). The overall prevalence of IBD was 80 per 100 000, with 46 per 100 000 for UC and 36 per 100 000 for CD. Estimated rates adjusted to total population showed that IBD more than triplicated from 2008 to 2017. The distribution of IBD demonstrated a South-to-North gradient that generally followed population apportionment. However, marked regional differences and disease clusters were identified that did not fit with conventionally accepted IBD epidemiological associations, revealing that the rise of IBD was variable. In some areas, loss of biodiversity was associated with high IBD prevalence. CONCLUSIONS When distribution is considered in the context of IBD prevalence, marked regional differences become evident. Despite a background of Westernization, hotspots of IBD are recognized that are not explained by population density, urbanicity, sanitation, or other indices but apparently are explained by biodiversity loss. Thus, the rise of IBD in developing countries is not uniform, but rather is one that varies depending on yet unexplored factors like geoecological conditions.

Zhang S, Sun W. Clinical implications of miR-223 in allergic conjunctivitis and related factors affecting disease recurrence. Clin Immunol 2022; 237:108966. [PMID: 35272010 DOI: 10.1016/j.clim.2022.108966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 02/26/2022] [Accepted: 03/03/2022] [Indexed: 11/03/2022]
Abstract
This study aims to explore the clinical implications of miR-223 in allergic conjunctivitis (AC) and the related factors affecting disease recurrence. 47 AC patients and 58 healthy controls were enrolled to measure miR-223 expression level, serum level of inflammatory mediators, and the correlation between miR-223 and inflammatory mediators. Subsequently, AC patients were followed up for six months to record disease recurrence and explore the risk factors affecting disease recurrence. Compared to the healthy controls, the miR-223 level was lower, while inflammatory cytokines and immunoglobulins levels were higher in AC patients. There was a negative correlation of miR-223 with inflammatory cytokines and immunoglobulins. Also, miR-223 was evidently lower in AC recurrence patients than those without recurrence. Moreover, family history, pet-keeping, and other allergic histories were among the risk factors contributing to AC recurrence. These results indicate that miR-223 plays an important role in the pathology of allergic conjunctivitis.

Cholinergic Urticaria: Clinical Presentation and Natural History in a Tropical Country. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7301652. [PMID: 32596363 PMCID: PMC7273400 DOI: 10.1155/2020/7301652] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 05/06/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND Cholinergic urticaria (CholU) is a subset of chronic inducible urticaria characterized by the recurrent pinpoint-sized wheals that are induced by exercising or increasing core body temperature. Currently, the data of CholU in tropical climate is still limited. OBJECTIVE To investigate the clinical features and natural course of CholU in a tropical country. MATERIALS AND METHODS This retrospective chart review study analyzed the data of CholU patients aged over 18 years who visited Siriraj Urticaria Clinic, Siriraj Hospital, Bangkok, Thailand, between January 2007 and September 2019. Demographic data, clinical presentations, and results of provocation tests and other laboratory investigations were evaluated and compared with other studies reported in temperate zones. RESULTS Sixteen out of 2,175 chronic urticaria patients (0.7%) were diagnosed with CholU. The median age of CholU patients was 28.0 ± 11.7 years with male predominance (56.3%). Three patients (18.8%) had a history of atopy. Fifteen patients (93.8%) were positive to the exercise provocation test. Nonsedating antihistamine drugs were a main treatment (73.8%). Six patients (37.5%) were in remission at the time of the study, with a mean duration 4.3 years. The Kaplan-Meier survival analysis demonstrated that 12.5%, 35.5%, and 67.9% of patients would have disease remission within 1 year, 5 years, and 13 years, respectively. CONCLUSIONS The prevalence of CholU differs in each geographic region and is found to be low in tropical countries with a median duration 4.3 years. The prevalence of atopy and anaphylaxis with CholU is also lower in tropical countries than in temperate.

Investigation of oral atopic diseases: Correlation between geographic tongue and fungiform papillary glossitis. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2020; 122:283-288. [PMID: 32540362 DOI: 10.1016/j.jormas.2020.05.025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 05/15/2020] [Accepted: 05/25/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION The correlation between oral lesions and atopy is not new, but few studies have investigated the prevalence of mucosal changes in diseases within the atopic spectrum, leading to conflicting data. Some studies found a possible relationship between geographic tongue, transient lingual papillitis and atopic diseases. AIM To investigate the frequency of geographic tongue and fungiform papillary glossitis in patients with atopic diseases, and its correlation with serum IgE levels and skin test results. MATERIAL AND METHODS The sample was comprised of participants with atopic diseases paired with participants who received negative puncture skin tests. All were submitted to stomatological and medical evaluations, prick test and oral cytopathological. RESULTS The female sex was more numerous in both groups. Mean age was 21 years. A total of 60 diagnoses of atopic diseases were obtained, with allergic rhinitis being the most prevalent. Fungiform papillary glossitis was the most frequent oral lesion in both groups, while geographic tongue was present in 2 cases (2%) in the test group and 2 (2%) in the control group. Atopic patients with fungiform papillary glossitis presented high serum IgE levels. In atopic patients with geographic tongue, the prick test positively identified extracts of Dermatophagoides pteronyssinus (100%) and Dermatophagoides farinae (100%). CONCLUSION Due to the low frequency of geographic tongue lesions found in the study, it is no possible to conclude if that could be an oral manifestation of atopy. However fungiform papillary glossitis is a common alteration in atopic and non-atopic patients and has a relationship with high IgE serum levels. However, the consolidation of this result requires a larger sample size.

Abstract
BACKGROUND Allergic diseases are recognized as a burden on the public health. They stand as one of the most common chronic diseases, especially in developed countries. Therefore, the objective of this study is to evaluate the association between the development of atopic allergy and the presence of food allergy in children, and food consumption. METHODS This multidisciplinary cross-observational epidemiological study was conducted among 1199 schoolchildren who were recruited in 4th grade and 5th grade (9-11 years old from Marseille). Data were collected by means of a standardized epidemiological questionnaire with a medical assessment focusing on allergic diseases, and questions on lifestyle and child nutrition (FFQ). RESULTS During the last 12 months, prevalence of allergic diseases were shown as follows: 41% of children presented allergic rhinitis symptoms, 24% reported having asthma related symptoms, while 28% suffered of eczema and 7% complained of food allergy. There was a significant association between food allergy and asthma symptoms (P-value<0.001, IC=[2.29-7.69]), eczema (P-value<0.001, IC=[2.37-8.32]) and allergic rhinitis (P-value<0.001, IC=[2.32-8.17]). Regarding dietary habits, the multivariate analysis shows that the consumption of vegetables (ORa=0.72 [0.64-0.74]) and fish (ORa=0.74 [0.50-1.09], ORa=0.66 [0.47-0.94] respectively) are associated decreased risk of developing asthma and allergic rhinitis symptoms, while fruit consumption (ORa=0.68 [0.45-1.03]) is associated with a decrease in eczema symptoms. CONCLUSION This study shows that the presence of a food allergy is strongly associated with allergic diseases. Indeed, the consumption of vegetables, fruits and fish seems to have a protective effect on the occurrence of these diseases.

The Potential Inhibitory Effects of miR-19b on Ocular Inflammation are Mediated Upstream of the JAK/STAT Pathway in a Murine Model of Allergic Conjunctivitis. Invest Ophthalmol Vis Sci 2020; 61:8. [PMID: 32150250 PMCID: PMC7401772 DOI: 10.1167/iovs.61.3.8] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Accepted: 01/05/2020] [Indexed: 01/14/2023] Open
Abstract
Purpose Thymic stromal lymphopoietin (TSLP) is a pro-allergic cytokine that initiates allergic inflammatory reaction between epithelial and dendritic cells (DCs). miR-19b was reported to suppress TSLP expression. The present study aimed to examine miR-19b expression, regulation, and function in allergic conjunctivitis (AC). Methods A murine model of experimental AC was induced in BALB/c mice by short ragweed pollen. The serum, eye balls, conjunctiva, and cervical lymph nodes (CLN) were used for the study. Gene expression was determined by RT-PCR, whereas protein production and activation were evaluated by immunostaining, ELISA, and Western blotting. Results In the murine AC model, miR-19b was aberrantly downregulated, whereas the levels of TSLP and p-STAT3, as well as the number of CD11c+ pSTAT3+ DCs were increased. Moreover, Th2 inflammatory cytokine expression was significantly increased. These severe phenotypes could be counteracted by either applying exogenous miR-19b mimic microRNAs or the JAK/STAT inhibitor CYT387. Moreover, overexpression of miR-19b repressed p-STAT3 expression and the number of CD11c+ cells in AC eye and CLN tissues. Conclusions These findings suggested that miR-19b reduced ocular surface inflammation by inhibiting Stat3 signaling via TSLP downregulation in a murine AC model. Moreover, the present study further demonstrated the clinical potential of applying miR-19b and anti-JAK/STAT therapies in the treatment of AC.

Abstract
PURPOSE OF REVIEW To examine the relationship between otitis media, allergic rhinitis, and age. RECENT FINDINGS Otitis media and allergic rhinitis are prevalent conditions with a controversial relationship. Some data suggest that these entities are significantly associated, either through allergic rhinitis inducing Eustachian tube dysfunction or through allergic pathophysiology simultaneously occurring intranasally and in the ear. Other studies, however, have refuted this relationship. For example, treatment with antihistamines does not reliably improve OME, making causation and association challenging to establish. Age may have an effect on the nature of the relationship between allergic rhinitis and otitis media, by impacting both the individual conditions and their association. Epidemiological, immunological, and adenoidal studies have suggested that differences occur with age, and this review encapsulates the related data and publications. We begin by evaluating how allergic rhinitis and otitis media each are affected by age, then evaluate the role that age may have in the relationship between the two conditions. Adult and pediatric literature are evaluated so as to include the full impact of age across patients' lifespan. Age induces changes in immunity, patterns of inflammation, and susceptibility to both allergic rhinitis and otitis media with effusion. Age may also be an effect modifier which impacts the nature of the relationship between these two conditions. The influence of age on the association between these highly prevalent conditions remains a topic of active study.

Abstract
Paeoniflorin (PF), one of the main effective ingredients from the root of Paeonia lactiflora Pall., was reported to possess antitumor, anti-inflammatory, and antiallergic properties. However, the roles of PF in activated human mast cell line, HMC-1 cells, have not yet been elucidated. Thus, the aim of this study was to examine the antiallergic and anti-inflammatory effects of PF on phorbol-12-myristate 13-acetate plus calcium ionophore (PMACI)-induced human mast cells and to identify the mechanism responsible for these effects. Our results demonstrated that pretreatment with PF effectively attenuated PMACI-induced production of tumor necrosis factor-α and interleukin 1β in HMC-1 cells. In addition, PF significantly suppressed PMACI-induced histamine release and caspase-1 activation in HMC-1 cells. Furthermore, PF prevented the activation of nuclear factor κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways in activated HMC-1 cells. In conclusion, we showed for the first time that PF attenuated the mast cell-mediated allergic inflammatory response through suppressing the NF-κB and MAPK signaling pathways.
