Exploring the relationship between asthma, its severity and anxiety symptoms in pediatric patients: a case-control study.

BACKGROUND: Asthma is a global health concern, especially among children, and is associated with various underlying mechanisms. Childhood exposure to early life stress and anxiety can potentially exacerbate asthma symptoms and complicate its management. While some studies have suggested the benefits of psychological therapies as adjuncts to medication in asthma management, evidence remains inconsistent, emphasizing the need for rigorous evaluation. METHOD: This case-control study involved 120 children aged 5-15, with 60 children having asthma and 60 healthy controls. Asthma severity was assessed based on EPR3 guidelines, while anxiety symptoms were measured using the Spence Children's Anxiety Scale (SCAS). Demographic data and asthma-related information were collected via questionnaires. Statistical analyses were conducted to explore the relationship between asthma and anxiety. RESULTS: Children with asthma exhibited significantly higher anxiety symptoms compared to those without asthma (p < 0.001). Subdomain analysis revealed elevated scores in separation anxiety (SA; p = 0.025), social phobia (SP; p < 0.001), agoraphobia (p = 0.004), and fears of physical injury (p < 0.001) in children with asthma. Furthermore, increased need for SABA, frequency of nocturnal symptoms, and asthma severity were associated with higher anxiety levels in pediatric asthma patients. CONCLUSIONS: This study highlights a significant association between asthma and heightened anxiety symptoms in children, particularly in domains, such as SA, SP, agoraphobia, and fears related to physical injury. However, limitations include reliance on self-evaluation questionnaires and the observational nature of the study, emphasizing the need for cautious interpretation.

Diagnosis and selection of alternative antibiotics in beta-lactams hypersensitivity reactions: Current recommendations and challenges.

Beta-lactam (BLM) antibiotics, including amino-penicillin and cephalosporins, are typically the first-choice treatment for bacterial infections. However, adverse reactions to these antibiotics are frequently reported, causing non-allergist physicians to select alternative broad-spectrum antibiotics that can have harmful consequences. Patients with unclear histories of hypersensitivity reactions to BLMs should undergo an allergy workup to establish a firm diagnosis, particularly when different drugs are prescribed simultaneously. However, finding the safest, most precise, and cost-effective methods for confirming BLMs hypersensitivity and selecting the most appropriate alternative BLM is uncertain, particularly in severe delayed reactions. This review aims to provide data and recommendations on the availability and validity of skin tests (STs), drug provocation test (DPT) protocols, based on the latest published literature and guideline. To make the process more practical, we focused on cross-reactivity between BLMs and diagnostic tests. There are two main novel aspects of this document: 1) For T-cell-mediated reactions, patient stratification into high, moderate, and low-risk groups based on the mortality and morbidity of adverse drug reactions. 2) For IgE-mediated reactions, stratification of individuals with isolated limited urticarial without anaphylaxis in a low-risk group and removal of the extensive limitation.

Quality of life in children with asthma compared to healthy children: a case-control study.

OBJECTIVE: Asthma is a chronic condition characterized by episodic wheezing, cough, and shortness of breath resulting from airway hyperresponsiveness and inflammation. Over 300 million people are affected worldwide, and its prevalence is increasing by 50% every decade. Assessing the quality of life in children with asthma is fundamental, as consistently poor health-related quality of life is associated with poorly controlled asthma. This study is aimed to evaluate and compare factors associated with HRQOL between healthy controls and children with asthma. METHODS: In the current case-control study, 50 children aged 8-12 years with asthma (cases) enrolled at outpatient hospital clinics by a trained pediatric allergist/immunologist (A.P.) and matched with 50 healthy controls by age and sex. All enrolled subjects were interviewed utilizing the PedsQL questionnaire to assess health-related quality of life; also, patient demographics, including age, sex, and family income status, were obtained from a questionnaire. RESULTS: A total of 100 children comprising 62 males and 38 females with a mean age of 9.63 ± 1.38 years, participated in this study. The average score of children with asthma was 81.63 ± 9.38, and the average score for healthy participants was 89.58 ± 7.91. We found that asthma was associated with a significant drop in health-related quality of life in this sample. CONCLUSIONS: The results indicated that the PedsQL score and its subscales, except social functioning, were significantly higher in children with asthma compared to healthy ones. Also, SABA use, nocturnal symptoms, and asthma severity are negatively related to the health-related quality of life.

Atypical Omenn Syndrome Due to RAG2 Gene Mutation, a Case Report.

Severe Combined Immunodeficiency (SCID), characterized by a profound decrease in both the number and function of T cells, is related to more than 20 different mutations. Recombination-activating gene (RAG) 1 and 2 seem to be two of the most common forms presenting with various manifestations, including typical SCID, Omenn syndrome (OS), atypical SCID (AS), or delayed onset combined immunodeficiency with granulomas. One interesting manifestation in RAG mutation is the change in the immunophenotype over time, even after hematopoietic stem cell transplantation (HSCT). As bone marrow transplantation (BMT) is the only curative treatment of SCID, it is necessary to differentiate between SCID and OS due to the different conditioning regimens (CR). We present a novel case of atypical SCID (SCID manifestations with more than 300 CD3+T cells) caused by RAG 2 gene mutation whose immunophenotype changed to atypical Omenn syndrome (all Omenn syndrome manifestations except rash, eosinophilia, and elevated IgE) over time. Differentiation of leaky SCID, SCID and Omenn syndrome in RAG mutation genes and overlap manifestations is important in treatment plan and prognosis.

Association of childhood croup and increased incidence of airway hyperreactivity in adulthood.

BACKGROUND: Some evidence suggests that childhood croup could be associated with increased incidence of adulthood bronchial reactivity, but its significance is uncertain. The aim of the present study was to evaluate the long-term outcome of early life croup. PATIENTS AND METHODS: This case-control study was conducted in 2010-2012 in Isfahan, Iran. The case group consisted of 164 adolescents with a history of severe croup in early life and an equal number of healthy controls without any history of croup or other chronic or recurrent respiratory diseases. The two groups were compared according to pulmonary function tests and bronchial reactivity (exercise challenge test). Statistical analyses were performed using the SPSS software package, version 20 (SPSS Inc., Chicago, IL, USA). P < 0.05 was considered significant. RESULTS: Baseline spirometric values (forced expiratory volume in 1st s (FEV1), forced volume capacity (FVC), FEV1/FVC, and forced expiratory flow at 25%-75% (FEF25-75) were similar in case and control groups. A reduction in FEV1 and FEF25-75 after exercise challenge test was seen in 9% and 12.8% of patients, respectively, whereas this was reduced in only 4.2% and 6.1% of the controls (P = 0.034 and P = 0.021, respectively). CONCLUSION: Our findings suggest that childhood croup might be a predisposing factor for bronchial hyperreactivity in adulthood. Longitudinal studies are necessary to confirm the clinical significance of these findings.
