ABSTRACT

INTRODUCTION:

There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp) in adenotonsillar tissue.

OBJECTIVE:

A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis.

METHODS:

Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients' serum by using polymerase chain reaction.

RESULTS:

Hp IgG was detected in 57 (89%) patients' serum. A total of seven tissue samples from 64 patients (10.9%) were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism.

CONCLUSION:

This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas. .
RESUMO

INTRODUÇÃO:

Há um debate atual sobre os efeitos da Helicobacter pylori (HpHp) no tecido adenotonsilar.

OBJETIVO:

Conduzimos um estudo clinico para avaliar a existência de Hp nos tecidos adenoideano e/ou adenotonsilar, os quais foram removidos cirurgicamente em decorrência de adenotonsilite crônica.

MÉTODO:

No total, 84 amostras de tecido obtidos de 64 pacientes foram analisadas para o gen fosfoglucosamina mutase para a detecção de Hp. Os casos positivos foram a seguir examinados para o gen associado à citotoxina, relacionado à virulência, usando-se o método de Reação de Polimerase em Cadeia (PCR).

RESULTADOS:

A IgG de Hp foi detectado em 57 (89%) soros de pacientes. Sete amostras de tecido de sessenta e quatro pacientes (10.9%) resultou positivo para o DNA de Hp, das quais cinco eram adenóides e duas eram tecido tonsilar. No PCR todas as amostras foram também positivas para o gen associado à citotoxina, o qual é um determinante de virulência.

CONCLUSÃO:

Esse estudo sugere que as crianças são expostas ao Hp nos primeiros anos de vida nessa província e que o Hp pode ter um papel na patogênese da adenotonsilite crônica, principalmente em áreas endêmicas. .
