Resum
OBJECTIVE
To determine Helicobacter pylori presence on antral lavages, adenoids and salival inmunoglobuline A on paediatric patients with chronic rhinosinusitis without nasal polyps (CRSsNP) and adenoid hypertrophy.
METHODS
Adenoid tissue, liquid obtained from antral lavages and saliva from 28 children diagnosed with CRSsNP, from the paediatric otorhinolaryngology practice of "Dr. Domingo Luciani" Hospital was taken and processed by means of polymerase chain reaction (PCR) using cagA, vacA and babA primers, also anatomopathological examination using Giemsa stain of the adenoids, determination of salivary specific secretory inmunoglobuline A (sIgA), socio-economic condition using the Graffar scale and associated gastrointestinal symptoms were assessed.
RESULTS
No evidence of Helicobacter pylori neither in antral lavages liquid nor adenoid tissue was found using PCR and Giemsa stain. sIgA was present in 28.6% of the subjects. The most frequently found symptoms were, diarrhea in 17.9%, distension and abdominal pain in 10.7%, 64.3% of the patients were in working (28.6%) and low middle (35.7%) classes.
CONCLUSIONS
Helicobacter pylori is not present neither in maxillary sinuses nor adenoid tissue of the evaluated patients, sIgA it is a non-invasive method for assessment of immunologic challenge with the bacteria, not the presence of acute or chronic infection.
