PURPOSE: Chronic cough in allergic rhinitis (AR) patients is common with multiple etiologies including cough variant asthma (CVA), non-asthmatic eosinophilic bronchitis (NAEB), gastroesophageal reflux-related cough (GERC), and upper airway cough syndrome (UACS). Practical indicators that distinguish these categories are lacking. We aimed to explore the diagnostic value of the fraction of exhaled nitric oxide (FeNO) and forced expiratory flow at 25% and 75% of pulmonary volume (FEF25-75 ) in specifically identifying CVA and NAEB in these patients...

The Mysterious Cough - a Case-Based Proposal of Differential Diagnosis Abstract. Cough is a frequent complaint in the general practice. Avoidance of overdiagnosis and underdiagnosis is essential. In case of acute cough or subacute (<8 week duration), red flags indicate the need for further evaluation, otherwise it is mostly self-limiting. In case of chronic cough (>8 week duration) and normal baseline examination and after cessation of smoking and medication with ACE-I, cough-variant asthma, gastro-esophageal reflux disease and upper airway cough syndrome are the main causes and should be assessed and empirically treated in a systematic manner...

The allergic airway diseases, including chronic rhinosinusitis (CRS), asthma, allergic bronchopulmonary mycosis (ABPM) and many others, comprise a heterogeneous collection of inflammatory disorders affecting the upper and lower airways and lung parenchyma that represent the most common chronic diseases of humanity. In addition to their shared tissue tropism, the allergic airway diseases are characterized by a distinct pattern of inflammation involving the accumulation of eosinophils, type 2 macrophages, innate lymphoid cells type 2 (ILC2), IgE-secreting B cells, and T helper type 2 (Th2) cells in airway tissues, and the prominent production of type 2 cytokines including interleukin (IL-) 33, IL-4, IL-5, IL-13, and many others...

Chronic cough is one of the most common complains for patients seeking medical attention in both general practice and respiratory specialist clinics. Cough variant asthma, eosinophilic bronchitis, upper airway cough syndrome, as well as gastro-esophageal reflux disease are common conditions associated with chronic cough, and cough variant asthma, eosinophilic bronchitis account for a higher proportion of patients with chronic cough in China than in Western countries. An older female predominance has been reported in most Western countries, which may be attributed to a higher cough reflex sensitivity in females, especially those post-menopausal females...

Cough is divided into two categories: acute cough lasting less than 3 weeks, and chronic cough lasting more than 8 weeks. Acute cough is usually triggered by a viral infection of the upper airways. Evidence of treatment effectiveness is low and management of acute cough is complex in clinical practice. Chronic cough is a common reason for consultation in medicine. The most frequent causes are upper airway diseases, gastroesophageal reflux disease, asthma, eosinophilic bronchitis, and drugs. Before investigation, smoking cessation and drug withdrawal must be achieved for 4 to 6 weeks...

Recently, there have been robust changes in our knowledge of the neurophysiology of cough and novel clinical etiologies. Specifically, cough hypersensitivity in adults and protracted bacterial bronchitis (PBB) in children have been increasingly investigated, and differences between chronic cough in children and adults have been widely reported. In young children, postinfectious cough, bronchiectasis, airway malacia, PBB, and asthma appear to be the main causes of cough; however, by adolescence, the causes of cough are more likely to become those common in adults, namely, gastroesophageal reflux, asthma, and upper airway syndrome...

Bronchiectasis has historically been considered to be irreversible dilatation of the airways, but with modern imaging techniques it has been proposed that 'irreversible' be dropped from the definition. The upper limit of normal for the ratio of airway to arterial development increases with age, and a developmental perspective is essential. Bronchiectasis (and persistent bacterial bronchitis, PBB) is a descriptive term and not a diagnosis, and should be the start not the end of the patient's diagnostic journey...

Background/Aims: Inhaled corticosteroids (ICS) are a treatment of choice for eosinophilic airway diseases, but their efficacy for other causes of chronic cough is controversial. Methods: We conducted a prospective observational study to determine the ICS efficacy and clinical predictors of response to ICS in patients with upper airway cough syndrome (UACS) or unexplained chronic cough (UCC). Sixty-eight patients with UACS and 33 patients with UCC (duration of cough ≥ 8 weeks) were treated with ICS: 250 µg of fluticasone propionate or 400 µg of budesonide twice a day at physician's discretion...

INTRODUCTION: Cough is induced by stimulation of structures innervated by the vagus nerve, including the upper and lower airways and distal esophagus. The Arnold nerve reflex describes cough resulting from stimulation of the external auditory canal, which is innervated by the auricular branch of the vagus. We have recently reported the increased prevalence of this reflex in adults, but not children, with chronic cough, relative to healthy adult and pediatric subjects. The prevalence of the Arnold nerve reflex in patients with pulmonary disease but without chronic cough has not been investigated previously...

Bronchiectasis is a clinical and radiological diagnosis associated with cough, sputum production and recurrent respiratory infections. The clinical presentation inevitably overlaps with other respiratory disorders such as asthma and chronic obstructive pulmonary disease (COPD). In addition, 4-72% of patients with severe COPD are found to have radiological bronchiectasis on computed tomography, with similar frequencies (20-30%) now being reported in cohorts with severe or uncontrolled asthma. Co-diagnosis of bronchiectasis with another airway disease is associated with increased lung inflammation, frequent exacerbations, worse lung function and higher mortality...

Chronic cough is a common complaint and a frequent cause of medical consultation. Its management can be difficult. We present here an overview of the current guidelines for the management of chronic cough. Different steps are detailed, including the initial research of an obvious etiology and alert signs that should lead to further investigation of underlying condition. The diagnosis of the most frequent causes: asthma, non-asthmatic eosinophilic bronchitis, gastroesophageal reflux disease and upper airway cough syndrome should be considered, assessed and treated accordingly...

INTRODUCTION: Cough exceeding 3-8 weeks was defined as chronic cough in various guides. Asthma is the most common cause of chronic-specific cough. Causes other than asthma include prolonged bacterial bronchitis and upper airway cough syndrome (UACS). Nitric oxide (NO) causes vascular smooth muscle relaxation, bronchodilation, and oxidant effects via its metabolite, peroxynitrite. An increase in NO results in inflammation, vasodilatation, and bronchial edema. MATERIALS AND METHODS: The study group included 90 patients aged 6-17 years selected from individuals presenting to the Pediatric Immunology and Allergic Diseases Clinic with cough persisting for 4 weeks and 30 other patients representing to the control group...

Chronic cough, that 10-38% outpatients have, is an important cause of morbidity and mortality. This symptom can be seen 3-40% of adult patients and reduces quality of life. 95% patients that cough chronically have one of these three diseases: upper airway cough syndrome, gastroesophageal reflux or asthma. In this review these three diseases and rare causes of chronic cough will be discussed and diagnostic steps will be explained.

Although chronic cough in adults (cough lasting longer than eight weeks) can be caused by many etiologies, four conditions account for most cases: upper airway cough syndrome, gastroesophageal reflux disease/laryngopharyngeal reflux disease, asthma, and nonasthmatic eosinophilic bronchitis. Patients should be evaluated clinically (with spirometry, if indicated), and empiric treatment should be initiated. Other potential causes include angiotensin-converting enzyme inhibitor use, environmental triggers, tobacco use, chronic obstructive pulmonary disease, and obstructive sleep apnea...
