Infectious bronchitis (IB) is a highly contagious disease of the respiratory and urogenital tract of chickens, caused by infectious bronchitis virus (IBV), a member of the family Coronaviridae. The disease is common throughout the world where chickens are produced commercially. PCR on reverse transcribed RNA is a potent technique for the detection of IBV. In comparison with classical detection ...

Background: Acute bronchitis, frequently emerging with the common cold is one of the most frequent causes of primary care consultations. It is a self-limiting disease which poses both high symptom burden to individuals and high financial burden to society. It is largely a viral disease (~50 % rhinovirus infection), but no causal (antiviral) treatment exists. Antibiotics, mucoactive agents, anti...

The present work aims to assess the international variation in the prevalence of chronic bronchitis and its main risk factor, smoking habits, in young adults of 35 centres from 16 countries. Respiratory symptoms and pulmonary function were assessed in 17,966 subjects (20-44 yrs), randomly selected from the general population, in the frame of the European Community Respiratory Health Survey. The...

Chronic bronchitis is common among smokers, often together with recurrent infectious exacerbations. Streptococcus pneumoniae and Haemophilus influenzae are the pathogens traditionally considered most important. N-acetylcysteine (NAC) treatment has been shown to reduce the number of infectious exacerbations in patients with chronic bronchitis. The mechanism behind this is unknown. We attempted t...

BACKGROUND Few studies present prospective data on the incidence of asthma. Its associations with sex and with prior and concurrent hay fever and eczema were examined in a nationally representative sample followed from birth to 23 years of age (British 1958 birth cohort). METHODS Reports of asthma or wheezy bronchitis, hay fever and eczema were obtained by interview of parents of children at ...

Background: Poverty is an important surrogate marker for obstructive airway diseases (OAD). Slum constitutes a habitat wherein various poverty related parameters are perpetually prevalent in the ambience. 1/6th of world population lives in slums yet there is no information regarding their health status in context to asthma and COPD. Aims: We investigated the prevalence of asthma and chronic-bro...

АСТМА ТА АЛЕРГІЯ, No 4 • 2013 Over a billion cases of acute respiratory infections are detected in the world annually,and the prevalence of respiratory diseases in children is 6-fold than in adults [1]. According to official World Health Organization statistics pathology of the respiratory system ranked first in the structure of infant morbidity [2]. The incidence of bronchitis predominates in ...

BACKGROUND Chronic obstructive pulmonary disease (COPD) has been consistently associated with increased risk of lung cancer. However, previous studies have had limited ability to determine whether the association is due to smoking. METHODOLOGY/PRINCIPAL FINDINGS The Environment And Genetics in Lung cancer Etiology (EAGLE) population-based case-control study recruited 2100 cases and 2120 contr...

Research on the association between chronic bronchitis and chronic obstructive pulmonary disease (COPD) exacerbations has led to discordant results. Furthermore, the impact of chronic bronchitis on mortality in COPD subjects is unclear.Within the Rotterdam Study, a population-based cohort study of subjects aged ≥45 years, chronic bronchitis was defined as having a productive cough for ≥3 months...

In the May issue of the Journal, King and Moores1 presented a very nice overview of asthma phenotypes and disorders that mimic asthma. That article was followed by a paper by McCormack and Enright2 that reviewed the process of making a diagnosis of asthma, including a brief overview of the differential diagnosis of asthma. I respectfully submit that missing from both papers is a description of ...
