Eosinophilic otitis media and comorbid asthma

Purpose of review Eosinophilic otitis media (EOM) is an intractable otitis media characterized by numerous eosinophils infiltrating the middle ear cavity, which is part of the upper airway. EOM shows a high rate of comorbidity with asthma. They are considered to have a ‘one airway, one disease’ relationship. Here, we summarize our current knowledge regarding the characteristics of EOM, EOM's relationship with asthma and the efficacy of optimal treatments for EOM. Recent findings The greater the severity of asthma, the more pronounced the development of EOM. Asthma control is usually inadequate in asthmatics who develop EOM, and appropriate strengthening of asthma inhalation therapy leads to improvement in the EOM. EOM severity can be divided into mild, moderate, and severe. Intratympanic infusion therapy using a topical steroid such as triamcinolone acetone is effective for mild EOM, whereas moderate EOM requires a systemic steroid in addition to triamcinolone acetone, and severe EOM forms granulation tissue that requires surgical removal. Recently, the effectiveness of molecularly targeted drugs is being reported, but more data need to be accumulated. Summary EOM and asthma are closely related. Optimal asthma treatment is important for treating EOM. Treatments commensurate with the severity of EOM are being developed.

Abstract BACKGROUND: Common variable immunodeficiency (CVID) is a heterogeneous group of disorders, characterized by recurrent upper and lower respiratory tract infections and some non-infectious clinical complications. OBJECTIVE: The current study aimed to provide a detailed evaluation of respiratory presentations and complications in a cohort of Iranian patients with CVID. METHODS: The present retrospective cohort study was conducted on 245 CVID patients who were recorded at the Iranian primary immunodeficiency disorders registry network. Respiratory manifestations were evaluated by reviewing clinical ...

Discussion This case demonstrates successful cure of pre-B-ALL complicating XLA by alloSCT with restoration of B-cell development and functional antibody response. We are aware of only one previous case of pre-B-ALL in an XLA patient (21), which suggests that human BTK deficiency in itself does not predispose to pre-B-ALL. However, there are data to suggest that BTK may act as a tumor suppressor, and BTK deficiency may predispose to tumor development following a “second hit.” Mice with a genetic deficiency in Slp65, a gene encoding an adaptor protein that functions together with BTK, have a block in progenito...

Abstract The relationship between otitis media with effusion (OME) and chronic rhinosinusitis with nasal polyposis (CRSwNP) remains unclear. We conducted a cross-sectional study of 80 consecutively presenting patients-42 males and 38 females, aged 15 to 76 years (median: 48)-who were diagnosed with CRSwNP. Our aim was to ascertain the prevalence of OME in CRSwNP patients, to determine whether the severity of CRSwNP affected OME, and to identify risk factors for OME in CRSwNP patients. The severity of CRSwNP was assessed on the basis of nasal symptoms, endoscopic nasal examinations, and Lund-Mackay staging scores. ...

Discussion Angioedema is edema that is non-pitting, self-limited occurring in non-dependent areas usually in an asymmetric distribution usually on the lips, face, hands, feet, genitals and also in the bowel. It usually develops over minutes to hours (often 1-2 hours) with resolution usually within 24-48 hours. Angioedema often occurs with urticaria but 20% of patients may have isolated angioedema. Acute allergic angioedema is often caused by drugs (including antibiotics and non-steroidal anti-inflammatory drugs), foods, infections, insects, various organic substances (i.e. latex, preservatives, formaldehyde, etc.), and oth...

Common variable immune deficiency (CVID) is a primary humoral immunodeficiency of adulthood characterized by reduced levels of at least 2 serum immunoglobulins isotypes and impaired antibody response to polysaccharide antigens. These immunologic defects predispose the patient to recurrent respiratory tract infections, such as recurrent sinusitis, otitis media, bronchitis, and pneumonia.1,2

The objective of this study was to analyze the symptoms and comorbidities of rhinitis, to compare AR to non-allergic rhinitis (NAR), and to reveal the phenotypes and features of AR in a Korean pediatric population. METHODS: Patients under 18 years of age with rhinitis symptoms were recruited from January 2013 to January 2015 by pediatric allergists. We analyzed symptoms, phenotypes, comorbidities, and allergen sensitization in this cross-sectional, multicenter study. RESULTS: Medical records were collected from 11 hospitals. The AR group has 641 (68.3%) patients, with 63.2% of boys and 7.5 (±3.4) years of me...

Conclusion: These characteristic features differ from those of known eosinophilic lung diseases, such as chronic EP, allergic bronchopulmonary mycosis, and eosinophilic granulomatous polyangitis. We would like to propose the concept of LHEA with accompanying SEM.

A 3-year-old girl of Iraqi descent was well until late infancy, when she developed frequent wheezing and recurrent infections, including otitis media, sinusitis, and pneumonia, for which she was treated with monthly oral antibiotics. She was diagnosed as having asthma and treated with bronchodilators, budesonide, and multiple courses of oral steroids. She had a history of mild eczema and red eyes, diagnosed as an allergy by an ophthalmologist. At 2 years of age, tympanostomy tubes were placed.
