Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract. Although commonly associated with allergic diseases, it is also rarely associated with autoimmune disorders. This case report describes a 17-year-old Filipino male with eosinophilic gastroenteritis, manifesting as abdominal pain, vomiting and diarrhoea. He had no allergic diseases, but he was previously diagnosed with chronic bullous disease. His symptoms improved with the initiation of corticosteroids. To date, this is the first case report of a patient with eosinophilic gastroenteritis and chronic bullous disease.

Background. Asthma is a complex disorder characterized by variable and recurring symptoms, airflow obstruction, bronchial hyperresponsiveness, and an underlying inflammation. Asthma is one of the most common chronic diseases in the world and its burden of disease is exceedingly high. According to current guidelines, the asthma action plan is a cornerstone in the management and control of asthma exacerbations. Written action plans are now recommended for all children with asthma as part of initial home management of acute wheezing episodes and exacerbations. Translating the written asthma action plan to Filipino and testing it for cultural content validity and reliability will make it useful on a wider scale in our country, help reduce morbidity, and improve asthma control in the Filipino pediatric population. Objectives. To perform content and cultural validation and reliability testing of the Filipino Written Asthma Action Plan (FWAAP). Methods. The Written Asthma Action Plan was translated to Filipino following conventional translational steps: 1) forward translation, 2) back translation, 3) pilot testing and validation, 4) final translated version. We conducted a cross-sectional study and administered the FWAAP during pilot testing among children and caregivers with asthma attending an asthma clinic. Results. We included 31 patients. The participants considered the FWAAP to be relevant to their disease, understandable, concise and useful in the management of asthma. The tool was shown to be highly consistent (Cronbach’s alpha coefficient = 0.9235 showing that the. Seigel and Castellan’s Kappa (Inter-rater or Inter-observer consistency) showed inter-rater agreement of 0.9615 (kappa of 0.7787) and 0.923 (kappa of 0.8846) respectively showing adequate inter-rater agreement. Conclusion. The Filipino asthma action plan is a reliable and valid tool for managing asthma in the home setting.

Background Anaphylaxis is a severe and life-threatening systemic hypersensitivity reaction. The incidence of anaphylaxis has increased significantly in recent years. Objective To identify predictors of serious outcomes among patients with anaphylaxis seen in the national tertiary hospital of the Philippines from 2015 to 2019. Methods Data was collected retrospectively through search of the medical records section and census reports on all patients diagnosed with anaphylaxis seen at the national tertiary hospital from 2015 to 2019. The patients' clinical profile, management, and outcome were extracted. Multiple logistic regression analysis was used to determine the association of clinical characteristics and physicians' management with the development of serious outcomes. Variable selection procedure through backward elimination method was used to determine significant predictors of serious outcomes of anaphylaxis. Data analysis was done using Stata 14 software. Results There were 300 patients with anaphylaxis seen at the Philippine national tertiary hospital from 2015 to 2019. Of the 300 patients, 179 were female (57.9%). The median age of the patients was 26 years old, with an interquartile range of 33 years. Only 75 patients (25%) had a past history of allergic disease. Majority of the patients (70%) had comorbidities. Drugs were the most common trigger of anaphylaxis (81.3%). Antibiotics were the most common type of drugs implicated (27%). Serious outcomes were noted in a total of 31 patients (10.3%). The significant predictors of serious outcomes in anaphylaxis are age (p = 0.034) and cofactors including use of beta-blockers and presence of acute infection (p Conclusion In the Philippine national tertiary hospital, the incidence of anaphylaxis increased by 240% in the past decade. Predictors of serious outcome in anaphylaxis include increased age and presence of cofactors such as beta-blocker use and presence of acute infection.

Allergic diseases, such as asthma, allergic rhinitis, eczema, and food allergy, are preventable diseases. Primary prevention strategies of allergic diseases have been in scrutiny. Effective prevention strategies maybe started prenatally, postnatally, during infancy, and even during childhood. These guidelines have been prepared by the Philippine Society of Allergy, Asthma and Immunology and the Philippine Society for Pediatric Gastroenterology, Hepatology and Nutrition. They aim to provide evidence-based recommendations for the dietary primary prevention of allergic diseases in children. The primary audience of these guidelines is all healthcare practitioners who manage patients with potential allergic conditions. These guidelines are based on an exhaustive review of evidences, mostly systematic reviews, randomized controlled trials, and cohort studies. However, there are still many gaps in the evidence of dietary primary prevention of allergic diseases.

BACKGROUND Atopic dermatitis is the most common chronic skin disease affecting the pediatric population. Probiotics have been proposed to be effective in preventing the development of pediatric atopic dermatitis. Although studies show promise for the use of probiotics, the evidence is still inconclusive due to significant heterogeneity and imprecision. OBJECTIVE To determine the comparative effectiveness of the different types of probiotic strains in preventing the development of atopic dermatitis among pediatric patients. METHODOLOGY A systematic search of Cochrane Library, MEDLINE, TRIP Database, and Centre for Research and Dissemination was conducted. Manual search of the reference lists and search for unpublished articles were also done. All randomized controlled trials available from inception until April 12, 2020, on the use of probiotics in the prevention of atopic dermatitis among children were included. The comparator groups considered are other probiotic strains and placebo. The primary outcome of interest was the development of atopic dermatitis. Two authors independently searched for articles, screened the articles for inclusion, appraised the articles using the Cochrane risk of bias tool version 2, and extracted the data. In case of disagreement, the two authors discussed the source of disagreement until consensus was reached. If consensus was not reached, an independent third party reviewer was consulted. Frequentist network meta-analysis was conducted using STATA 14 software. The ranking probabilities and surface under the cumulative ranking curve (SUCRA) values were obtained to determine ranking of the different probiotic strains based on efficacy and safety data. RESULTS We included 21 original studies represented by 35 records and a total of 5406 children with atopic dermatitis as diagnosed by clinicians or fulfillment of validated diagnostic criteria. All studies were randomized placebo-controlled trials. The top 3 probiotic preparations in terms of efficacy in reducing the risk of atopic dermatitis are Mix8 (Lactobacillus paracasei ST11, Bifidobacterium longum BL999), LP (Lactobacillus paracasei ssp paracasei F19) and Mix3 (Lactobacillus rhamnosus GG, Bifidobacterium animalis ssp lactis Bb-12). Mix8 compared with placebo probably reduces the risk of atopic dermatitis based on low-quality evidence (RR = 0.46, 95% CI 0.25-0.85). Mix3 compared with placebo also probably reduces the risk of atopic dermatitis based on low-quality evidence (RR = 0.50, 95% CI 0.27-0.94). It is uncertain whether LP compared with placebo reduces the risk of atopic dermatitis due to very-low-quality certainty of evidence (RR = 0.49, 95% CI 0.20-1.19). In terms of adverse events, LGG may slightly lead to less adverse events compared with placebo based on low-quality evidence (RR = 0.70, 95% CI 0.32-1.52). Mix4 may slightly lead to more adverse events compared with placebo based on low-quality evidence (RR = 1.06, 95% CI 0.02-51.88). Based on subgroup analysis of studies involving infants, Mix3 compared with placebo probably reduces the risk of atopic dermatitis based on low-quality evidence (RR = 0.46, 95% CI 0.22-0.97). In the subgroup analysis of studies where probiotics were administered to pregnant women and to infants, LRH compared with placebo probably reduces the risk of atopic dermatitis based on moderate-quality evidence (RR = 0.54, 95% CI 0.26-1.11). CONCLUSION Certain probiotic preparations demonstrate efficacy in reducing the risk of developing atopic dermatitis when administered to pregnant women, infants, or both.
