chronic granulomatous disease represents a group of inherited disorders of phagocytic system wherein recurrent infections are seen at different sites especially in the respiratory system. to determine the clinical spectrum of respiratory manifestations in chronic granulomatous disease patients, in this retrospective study, we used data from iranian primary immunodeficiency registry. the diagnos...

BACKGROUND Respiratory failure is a serious complication that can adversely affect the hospital course and survival of multiply injured patients. Some studies have suggested that delayed surgical stabilization of spine fractures may increase the incidence of respiratory complications. However, the authors of these studies analyzed small sets of patients and did not assess the independent effect...

objective neuromuscular disorders (diseases of the motor unit), can cause respiratory problems such as impaired cough reflex, chest deformity, recurrent pneumonia and acute respiratory failure; these are the worst most common complications of these diseases and the leading cause of death in such patients (1, 2). their management hence, very often, entails admission to the pediatric intensive ca...

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new pandemic virus, a global concern, and has threatened human health. This virus binds to the Angiotensin-Converting Enzyme 2 (ACE2) that is expressed on different cells, especially on the alveolar cells. So the virus can enter the lung cells and causes respiratory syndromes. In Coronavirus Disease 2019 (COVID-19)  that is cause...

Normal carp serum contains inhibitory and stimulatory factors for macrophage and neutrophilic granulocyte respiratory burst activity. As stimulatory factors were only effective in combination with phorbol myristate actetate (PMA) activation, it is concluded that they are probably linked to protein kinase C activation. Both the stimulatory and inhibitory factors are heat stable. Macrophage- and ...

BACKGROUND Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infection in infants. Preterm birth, in addition to several demographic and environmental factors, increases the risk for development of severe RSV infection. The purpose of this study was to describe differences in risk factors and protective factors between preterm birth (up to 35 weeks' gestational age...

Bacterial pathogens are a leading cause of lung infections and contribute to acute exacerbations in patients with chronic respiratory diseases. The innate immune system of the respiratory tract controls and prevents colonization of the lung with bacterial pathogens. Forkhead box transcription factor family O (FOXO) transcription factors are key regulators of cellular metabolism, proliferation, ...
