Identification of viral and bacterial etiologic agents of the Pertussis-like syndrome in children under 5 years old hospitalized

Abstract

Objective: To study the presence of 8 respiratory viruses (Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, Parainfluenza-1, Parainfluenza-2 and Parainfluenza-3) and atypical bacteria (Mycoplasma pneumonia and Chlamydia pneumonia) in samples from Peruvian children under 5 years-old previously analyzed for Bordetella. Pertussis. Methods: A secondary data analysis was performed from a previous cross-sectional study conducted in children with a probable diagnosis of Pertussis from January 2010 to July 2012. All samples were analyzed via Polymerase Chain Reaction (PCR) for the follow ing

Retrospective study of clinical characteristics and viral etiologies of patients with viral pneumonia in Beijing

“…10 However, due to high cost of viral testing, only a few patients with viral pneumonia have a chance to be detected. 11 In addition, the etiology of viral pneumonia may be closely related to many factors such as age, geographic area, season, immune status and medical conditions. 12 In order to identify potential viruses of viral pneumonia, we collected clinical and demographic data for patients with viral pneumonia at general hospitals in Beijing and conducted virus testing and viral load analysis on different respiratory samples.…”

Analysis of Multiple Factors Involved in Pertussis-Like Coughing

“…In Peru, the most common pathogen isolated in laboratory was Adenovirus (49%), followed by B pertussis (41%), Mycoplasma (26%), and Influenza-B (19.8%). 6 In Iran, RSV was the most detected microorganism, and then B pertussis (18%), Adenovirus (16%), Influenza-A (11%), and Mycoplasma (10%). 15 Duration of pertussis-like coughing was associated with many factors, the most significant one being whether or not the pregnant women as well as infants received vaccine.…”

“…This coughing manifested itself as paroxysmal and spasmodic, as in pertussis. 6 In most cases, it was accompanied by multitudinous clinical manifestations, such as inspiratory whoop, apnea, posttussive vomiting, and wheeze. 7,8 Prolonged pertussis-like coughing would bring about numerous complications, including pneumonia, convulsions, cerebral hemorrhage, encephalopathy, and even death.…”
