Serum total IgE (tIgE) is frequently used in the diagnosis of allergic diseases in Mosul city and Iraq. However, neither normal nor elevated levels can exclude or confirm the diagnosis of these diseases. Here, we tried to evaluate the validity of tIgE in the diagnosis of allergic asthma(AS), allergic rhinitis(AR) and atopic dermatitis(AD) in a sample of Mosul population, to set up an optimum cut-off value for diagnosis of these diseases and to study its correlation with different parameters that might affect its level. 38 patients with AS, 27 with AR, 46 with AD and 45 healthy controls were included in this study. tIgE were determined by ELISA and compared between allergic diseases and controls. Blood eosinophilia was ascertained and correlated with tIgE levels. The geometric means of tIgE were 316.87 IU/ml (95% CI: 234.69 to 427.82) in AS, 262.07 IU/ml (95% CI:174.24 to 394.18) in AR and 270.48 IU/ml (95% CI:202.57 to 361.16) in AD compared to 16.90 IU/ml (95% CI:12.32 to 23.18) in healthy controls. tIgE in allergic diseases was significantly increased in comparison to healthy controls ( <.0001). Female gender influenced tIgE in AS, but not in AR or AD. tIgE predominated in younger age groups; however, no significant difference was found between younger and older groups. Optimum values for tIgE with best discriminative accuracy were 77 IU/ml for AS and 81 IU/ml for AR and AD. Eosinophils count appeared to be a useful adjunct, and correlate well with tIgE in the diagnosis of allergic diseases.

Background: Some studies have suggested that the forced expiratory flow between 25 and 75% of vital capacity (FEF) can be used as an early marker of bronchial hyperresponsiveness (BHR) in asthma and allergic rhinitis (AR), but is highly variable. Here, we aimed to assess whether the FEF can be used to diagnose BHR in patients with asthma-like symptoms and AR.

Allergic asthma is a chronic complex airway disease characterized by airway hyperresponsiveness, eosinophilic inflammation, excessive mucus secretion, and airway remodeling, with increasing mortality and incidence globally. The pathogenesis of allergic asthma is influenced by various factors including genetics, environment, and immune responses, making it complex and diverse. Recent studies have found that various cellular functions of mitochondria such as calcium regulation, adenosine triphosphate production, changes in redox potential, and free radical scavenging, are involved in regulating the pathogenesis of asthma.

Introduction: Omalizumab, an anti-IgE monoclonal antibody, is effective in treating antihistamine-refractory chronic spontaneous urticaria (CSU). However, tapering strategies for omalizumab are currently not well-studied, and patients may be treated longer than needed. Here, we present the rationale and design of the EXtending Omalizumab Treatment Intervals in patients with Chronic spontaneous urticaria trial, a multicentre, randomised, open-label, non-inferiority clinical trial.

Background: Patient-reported outcomes (PROs) have become indispensable measures in allergic rhinitis (AR) clinical trials. However, there is currently no scale specifically designed for the Chinese population. This study aimed to develop and validate the patient-reported outcome scale for allergic rhinitis (AR-PRO) to provide a reliable tool for AR patients in China.
