Allergic rhinitis causes major illness and disability worldwide, but it is still underdiagnosed and undertreated. Allergic rhinitis is a risk factor for both the development and for exacerbations of asthma. Up to 30% of patients with rhinitis suffer from asthma, and the majority of patients with asthma suffer from rhinitis. Measurements of allergic status can help to identify risk factors that ...

Results Total 152 patients were included and their average age (SD) were 66.83 years (6.52), 73% women, 78% Caucasian and 22% Hispanic. Arterial hypertension was the most frequent comorbidity (27%), followed by chronic rhino sinusitis (14%), RGE (10%), diabetes (5%) and obesity (5%). Other comorbidities were also searched, but they were only found in a few patients, such as eosinophilia esophag...

Allergic rhinitis affects a fifth of the population in industrialised countries and sleep disturbance has emerged as one of the major impacts of allergic rhinitis on patients. Sleep disturbances and its consequences on daytime sleepiness and fatigue affects the health related quality of life negatively and contributes significantly to patients’suffering and major health economic costs. Experime...

OBJECTIVES The primary aim of this study was to assess whether one can use levels of nasal nitric oxide (nNO) and exhaled nitric oxide (eNO) as a means of evaluation in allergic rhinitis. METHODS We used a chemiluminescence analyzer to measure nNO and eNO in normal controls (n=34) and allergic rhinitis patients (n=35), and compared these measurements with various parameters of clinical sympto...

Allergic rhinitis is associated with elevated serum IgE levels. IgE response is mediated by the high-affinity IgE receptor (FcεRI), which is polymorphic. Studies analyzing the association between allergic rhinitis and FcεRI variants have been conducted with controversial results. The objective of this study is to analyze, in 1,041 individuals, the putative clinical association of allergic rhini...

OBJECTIVE To study if nasal endoscope can be a reliable tool in assessing patients with allergic rhinitis. MATERIALS AND METHODS A prospective study. Patients who were diagnosed with allergic rhinitis underwent a nasal endoscopic examination performed by two physicians blinded to the scoring of each other. A correlation was made among symptom severity, endoscopic findings, and interrater vari...

BACKGROUND Asthma and allergic rhinitis are the two most common chronic disorders in childhood and adolescence. To date, no study has examined the impact of comorbid allergic rhinitis on asthma control in children. OBJECTIVE To examine the prevalence of allergic rhinitis in children with asthma, and the impact of the disease and its treatment on asthma control. METHODS A cross-sectional sur...

Patients with chronic diseases, including chronic respiratory diseases, usually have considerably impaired sleep quality that may increase the frequency of exacerbations and severity of symptoms, lead to difficulty in patient management, and reduce quality of life (QOL). During the last few decades, several studies have shown that, in addition to the classic signs of sneezing, nasal itching, rh...

conclusions our findings did not support the effect of cigarette smoking on spt reactivity to pollen and weeds aeroallergens. however, male were significantly more sensitive than female in terms of sensitivity to some allergens. results the results of this study indicated that 41.4% of patients with allergic rhinitis was smoker with ages ranged from 15 to 70 years. the result of this study also...

allergic rhinitis  (ar) is  an  inflammatory  disorder  of  the  nasal  mucosa  with  high morbidity and prevalence. natural killer (nk) cells might have a role in ar. we aimed to evaluate the changes of the markers and receptors on nk cells in ar patients compared to the non-atopic controls. flow  cytometric  analysis was  used  with  double  staining  of  the  peripheral  blood mononuclear ce...
